PREFACE 


This  treatise  is  the  outgrowth  of  a  volume,  by  the  author,  entitled  Notes  on 
Obstetrics,  and  used  for  fourteen  years  as  a  text -book  })y  the  junior  and  senior 
classes  at  the  Northwestern  University  Medical  School. 

Throughout  its  pages  the  author  has  constantly  held  in  view  the  needs  of  the 
general  practitioner  and  the  student.  Adequate  space  has  been  allowed  the  purely 
scientific  subjects,  and  their  direct  bearing  on  daily  practice  has  always  been  clearly 
emphasized. 

Diagnosis  has  been  made  a  particular  feature,  and  the  relations  of  obstetric 
conditions  and  accidents  to  general  medicine,  surgery,  and  the  specialties  have  been 
fully  brought  out.  Polemic  discussion  has  been  studiously  avoided,  at  the  risk, 
perhaps,  of  sometimes  being  too  dogmatic. 

In  the  preparation  of  the  volume  the  works  of  the  world's  greatest  authorities 
and  the  recent  literature  have  been  thoroughly  studied,  but  the  opinions  expressed 
are  mainly  the  result  of  the  author's  own  experience  in  hospital,  dispensary',  con- 
sultation, and  private  practice.  TAventy-one  years'  experience  as  a  teacher  of 
physicians,  students,  and  nurses  is  reflected  in  these  pages. 

Lengthy  bibliographies  have  been  avoided,  but  sufficient  recent  references  are 
given  to  enable  the  investigator  to  find  all  the  literature. 

For  the  student,  oAA-ing  to  the  crowded  condition  of  the  modern  medical  curric- 
ulum, brevity  and  system  are  essential,  and  the  underlying  principles  of  the  art 
must  be  brought  out.  The  practitioner  needs  a  wealth  of  detail  and  of  illustration 
to  tell  him  what  to  do  in  a  given  case.  To  accomplish  these  purposes  in  a  single 
volume  two  sizes  of  type  have  been  used.  Less  important  matter  and  details  of 
treatment  have  been  put  in  smaller  tj-pe.  For  the  same  reasons  lengthy  descrip- 
tions of  operations  are  omitted  from  the  text,  antl  put  as  full  explanatory  legends 
under  the  illustrations  depicting  the  successive  steps  of  the  procedure.  By  study- 
ing the  pictures  serially,  the  reader  will  be  better  able  to  follow  the  operation  than 
by  referring  to  them  from  a  distant  text. 

The  subject  matter  is  divided  into  four  parts:  The  Physiology  of  Pregnancy, 
Labor,  and  the  Puerperium;  The  Conduct  of  Pregnancy,  Labor,  and  the  Puer- 
perium;  The  Pathology  of  Pregnancy,  Labor,  and  the  Puerperium;  and  Operative 
Obstetrics.  Such  an  arrangement  allows  the  ea.sy  division  of  the  subject  to  fit  the 
usual  college  curriculum,  the  Physiology'  and  Conduct  of  Pregnancy,  Labor,  and 
the  Puerperium  being  in  the  junior  year,  and  the  Pathology  of  Pregnancy.  Labor, 
and  the  Puerj)erium,  with  Oi)erative  Obstetrics,  in  the  senior  year. 

With  very  few  exceptions  the  illustrations  are  original,  having  been  drawn 
under  the  supervision  of  the  author  from  fresh  specimens,  operations  on  the  living 
and  on  the  manikin,  and  from  original  photographs  taken  by  himself.  To  Bumm's 
matchless  work  the  author  is  indebted  for  many  ideas,  antl  for  these,  as  well  as  for 
permission  to  copy  some  of  his  plates,  the  author  is  profoundly  grateful. 

James  Kelly  Parker  drew  mo.^t  of  the  pictures;  Grace  Amidon  did  all  the  mi- 
croscopic ones;  and  Hermann  Becker,  of  Baltimore,  those  of  the  pelvic  floor  and 
4he  Porro  operation.  The  tireless  labor  these  artists  put  upon  their  work,  which 
has  extended  over  a  i:)eriod  of  eight  years,  is  deeply  appreciated. 
""  The  material  for  the  illustrations  came  mainly  from  the  Chicago  L^ing-in 
Hospital.     The  microscopic  and  wet  prei)arations  were  generously  furnished  by

INTRODUCTION 


Obstetrics  is  that  part  of  the  science  and  art  of  medicine  relating  to  the  func- 
tion of  reproduction.  The  word  obstetrics  probably  comes  from  the  Latin  06  and 
stare,  "to  stand  before,"  "to  protect."  While,  strictly,  it  should  be  ai)i)li('d  to  child- 
birth or  parturition,  usage  justifies  its  application  to  all  the  phases  of  reproduction. 
" Midwifery  "  and  "tocology  "  are  synonyms  for  obstetrics.  The  function  of  repro- 
duction is  a  closed  cycle  of  events,  interposed  in  the  life  of  a  woman,  and  comprises 
five  periods — conception,  pregnancy,  labor,  lactation,  and  involution. 

The  union  of  the  male  element  of  propagation,  the  spermatozoid,  ^^-ith  the 
corresponding  female  element,  the  ovum,  in  the  genital  tract  of  the  woman,  results 
in  the  formation  of  a  cell  which  is  capai)le  of  attaching  itself  to  the  uterine  wall  and 
developing  into  a  fully  matured  individual  resembling  its  parents.  The  fusion  of 
these  two  procreative  elements  is  called  conception.  The  production  of  a  ripe 
human  ovum  requires  about  ten  lunar  months — i.  e.,  pregnancy  lasts  about  two 
hundred  and  eiglity  days,  antl  on  the  completion  of  this  period  the  uterus  expels 
its  contents  into  the  external  world,  the  process  being  called  labor,  or  parturition. 
The  reproductive  cycle  is  continued  by  the  brea.sts  taking  up  the  further  nourish- 
ment of  the  child, — lactation, — and  is  completed  when  the  pelvic  organs,  concerned 
in  the  process,  return  to  their  former  condition.  This  function  is  called  involution. 
This  cycle  may  be  repeated  more  or  less  often  during  the  periotl  of  reproductive 
activity  of  the  woman,  which  extends  from  puberty  to  the  menopause.  One  de- 
mands that  it  should  not  cause  her  death  nor  injure  her  health,  and  that  the  child 
be  born  alive,  well,  and  capable  of  continued  extra-uterine  existence. 

Unfortunately,  this  standard  is  seldom  attained.  The  process  of  reproduction 
is  disturbed  l)y  many  pathogenic  influences  in  all  the  periods  of  the  cycle,  and  many 
permanent  structural  changes  are  inaugurated.  The  study  of  all  these  processes, 
both  normal  and  pathologic,  is  the  science  of  obstetrics;  the  application  of  this 
scientific  knowledge  and  that  derived  from  intelligent  experience  at  the  bedside  of 
the  patient  comprises  the  art. 

In  the  course  of  the  study  of  obstetrics  it  will  be  seen  that  the  function  of  gesta- 
tion affects  every  organ  in  the  woman's  body,  and,  conversely,  all  conditions,  med- 
ical or  surgical,  have  a  more  or  less  direct  influence  on  the  process  going  on  in  the 
uterus.  The  child,  too,  has  its  own  physiology  anil  pathology,  l)oth  medical  and 
surgical.  The  ol)stetrician,  therefore,  must  not  alone  be  well  versed  in  his  j)articular 
science  and  art,  but  he  must  also  be  an  internist,  a  surgeon,  and  a  pediatrist.  The 
borderlands  of  obstetrics,  with  medicine,  surgerj',  and  pediatrics,  are  narrow  and 
intimate.  In  some  universities  the  chairs  of  obstetrics  and  of  g>'necology  are  com- 
bined, it  being  held  that  the  relations  of  the  two  i^ranches  of  medicine  are  so  inti- 
mate that  their  separation  is  artificial  and  impractical.  The  olistetrician  should  not 
be  a  "midwife,"  caring  only  for  actual  i)irths — his  duty  is  to  treat  all  the  disea.ses 
and  accidents  that  have  to  do  with  the  reproductive  function.  Thus  he  must  as 
skilfully  repair  an  old  perineal  laceration  as  a  new  one,  or  treat  .sterility,  a.s  well  as 
the  surgical  complications  of  pueri)eral  infection.  He  nuist  l)e  able  to  remove  a 
ruptured  uterus,  extirpate  ovarian  cysts  complicating  labor,  as  well  as  perform 
cesarean  section. 

While  obstetrics  is  the  most  difficult  and  anluous  of  medical  practice,  it  at  the 


xii  INTRODUCTION 

same  time  is  the  most  satisfying.  Nowhere  can  the  ph3'sician  accomplish  so  much, 
both  in  prevention  of  disease  and  accidents  and  in  treatment  and  operation.  The 
accouchem-  very  often  has  the  positive  conviction  that  without  him  either  mother 
or  child,  or  both,  would  have  perished.  With  the  erection  of  model  maternity 
hospitals,  the  use  of  anesthetics,  and  the  employment  of  sufficient  assistants  for  the 
conduct  of  parturition  the  practice  of  obstetrics  is  being  divested  of  most  of  its  ob- 
jectionable features,  and  with  the  public  there  is  a  growing  sentiment  toward  the 
emploj'ment  of  obstetric  specialists.  These  circumstances  all  tend  to  make  the 
field  of  obstetrics  more  inviting  to  the  ambitious  physician,  and  will  conduce  to 
more  rapid  advance  in  both  its  science  and  art.  The  broader  conception  of  the 
scope  of  obstetrics  referred  to  above  will  also  work  to  the  same  happy  result. 

Statistics  show  that  there  is  need  for  this.  It  is  generally  conceded  that  the 
practice  of  obstetrics  is  on  a  low  plane.  Many  reasons  have  been  advanced  to  ac- 
count for  it,  but  in  my  opinion  the  basic  cause  is  the  prevalence  of  the  notion  that 
childbirth  is  a  normal  function. 

Is  labor  in  the  woman  of  today  a  normal  function?  I  say  it  should  be,  but  is 
not.  Imperfect  as  our  statistics  are,  a  little  more  than  one-half  of  the  area  of  the 
United  States  being  registered,  and  the  returns  from  the  registered  portion  being 
incomplete,  we  know  that  8500  women  annually  die  in  childbirth.  We  can  form  no 
conception  of  the  late  or  postponed  mortality  from  injury  received  during  labor, 
and  diseases  acquired  during  pregnancy  and  the  puerperium,  nor  can  any  one  tell 
how  many  women  die  from  childbirth  but  are  buried  under  another  diagnosis.  I 
feel  perfectly  safe  in  stating  that  over  20,000  women  die  in  the  United  States  every 
year  from  the  direct  and  indirect  effects  of  labor. 

The  immense  amount  of  invalidism  resulting  from  childbirth  is  absolutely  un- 
measurable,  but  we  know  that  annually  hundreds  of  thousands  of  women  flock  to 
our  hospitals  for  the  repair  of  injuries  and  for  relief  from  the  effects  of  diseases  con- 
tracted during  labor.  It  is  safe  to  say  that  50  per  cent,  of  women  who  have  had 
children  bear  the  marks  of  injury,  and  will,  sooner  or  later,  suffer  from  them.  Lacer- 
ation of  the  pelvic  floor,  of  the  supports  of  the  uterus,  bladder,  and  vagina,  occur  in 
every  labor.  This  fact,  easily  proved  clinically  by  any  accoucheur,  recently  was 
demonstrated  by  the  anatomist  Tandler.  The  late  consequences  of  laceration  of 
the  pelvic  floor,  such  as  dislocation  of  the  pelvic  organs,  especially  uterus  and  blad- 
der, infections  of  the  genital  tract,  congestive  conditions  of  the  uterus,  tubes,  and 
ovaries,  cystitis,  ureteritis,  pyelitis,  etc.,  prolapse  of  the  rectum, — indeed,  a  host  of 
diseases,  some  fatal,  and  all  inimical  to  the  enjoyment  of  life, — all  these  conditions 
and  others  that  could  be  named  in  considerable  number  that  follow  even  natural 
delivery  stamp  the  function  of  reproduction  in  w^omen  as  abnormal.  Between  3 
and  5  per  cent,  of  children  die  during  delivery,  and  a  great  many  are  permanently 
crippled  })y  the  forces  of  labor. 

Mauriceau  epigrammatically  called  pregnancy  a  disease  of  nine  months'  dura- 
tion. Sir  James  Y.  Simpson  said  that  "parturition  is  always  physiologic  in  its 
object,  but  not  in  some  of  the  phenomena  and  peculiarities  wiiich  attend  upon  it  in 
civilized  life."  Engelman,  after  comparing  the  labors  of  j^rimitive  and  civilized 
peoples,  says  that  a  simple,  natural  la))or  is  no  longer  possil^le,  and,  further,  "the 
parturient  sufiers  under  the  continuance  of  the  old  prejudice  that  labor  is  a  physio- 
logical act."  Kehrer  said  that  there  was  no  sharp  line  between  physiologic  and 
pathologic  pregnancy.  J.  O.  Polak,  in  1910,  said  that  parturition  is  rapidly  becom- 
ing a  pathologic  phenomenon.  F.  S.  Newell  says  that  we  must  realize  that  "some- 
thing has  gone  wrong  with  this  normal  physiologic  process,"  or  that  the  present 
methods  are  not  efficacious. 

Can  a  function  so  perilous,  that  in  spite  of  the  best  care,  if  kills  thousands  of 
women  everj^  year,  that  leaves  at  least  a  quarter  of  the  women  more  or  less  invalided, 
and  a  majority  with  permanent  anatomic  changes  of  structure,  that  is  always  at- 


INTRODUCTION  XllI 

tended  by  severe  pain  and  tearing  of  tissues,  and  that  kills  3  to  5  per  cent,  of  chil- 
dren—can such  a  function  be  called  normal? 

A  text-book  is  not  the  place  for  an  extended  discussion  of  a  subject  of  this 
kind,  but  the  author  is  convinced  that  not  the  majority,  Init  the  minority,  of  labor 
cases  is  normal,  and  tiiat  not  until  the  pathologic  dignity  of  oljstetrics  is  fully 
recognized  may  we  hope  for  any  considerable  reduction  of  the  mortality  and 
morbidity  of  childbirth.

PART  I 

THE  PHYSIOLOGY  OF  PREGNANCY,  LABOR,  AND 
THE  PUERPERIUM 

SECTION  I 
PHYSIOLOGY   OF    PREGNANCY 


CHAPTER  I 
PUBERTY,  OVULATION,  AND  MENSTRUATION 

Puberty. — At  birth  a  girl  and  a  boy  baby  are  much  ahke.  A  close  study  will 
show  small  differences;  the  boy  weighs,  on  the  average,  one-fourth  of  a  pound  more, 
the  head  is  a  little  harder  and  larger,  absolutely  and  also  relatively  to  the  bodj'; 
a  difference  in  the  pelvis  is  also  discernible :  the  female  pelvis  is  larger  and  shallower 
than  the  male,  and  this  is  also  true  of  the  lower  animals.  More  boys  are  born 
than  girls — 105  to  100,  a  proportion  that  prevails  the  world  over,  and  for  all  the 
years,  but  since  more  boys  die  during  labor — 1  in  16 — and  during  the  first  years  of 
life,  this  proportion  is  reversed,  so  that  later  the  females  preponderate. 

During  the  first  years  the  characteristics  of  the  sexes  gradually  become  more 
marked,  and  as  soon  as  the  child  walks  the  differentiation  becomes  apparent.  The 
girl  develops  mentally  and  physically  earlier  than  the  l)oy,  and  one  can  sooner 
discover  in  her  those  traits  of  the  female  that  distinguish  it  in  later  life.  Sexually, 
the  differences  are  less  marked  until  the  age  of  eight  to  ten  years,  when  in  the  girl 
a  change  begins.  In  the  boy  it  is  noticed  a  few  years  later.  This  change  is  called 
puberty,  or  in  girls,  menarchc  (from  Greek  ijLr]v  apxv),  and  may  l)e  defined  as  that 
period  in  the  life  of  the  individual  when  it  becomes  capal)le  of  reproduction.  The 
changes  are  more  rapid  and  marked  in  the  female — indeed,  her  sexual  life  is  more 
intense  and  plays  a  greater  role  in  her  existence.  INIadame  de  Stael  said:  "L'amour 
n'est  qu'une  episode  de  la  vie  de  I'homme;  c'est  I'histoire  tout  entiere  de  la  femme." 

The  girl  passing  into  womanhood  changes  physically  and  jisychically.  The 
pelvis  enlarges,  the  limbs  round  out  with  fat,  the  neck  grows  more  graceful,  and 
the  angularity  of  the  Ixxly  is  replaced  by  graceful  curves.  Th(^  general  carriage 
of  the  body  is  more  womanly,  and  the  movements  of  the  person  actiuire  dignity. 
The  breasts  enlarge,  become  more  prominent,  fuller,  and  firmer, the  result  of  g^o^^•th 
of  the  gland  tissue  and  the  addition  of  fat;  the  nipple  becomes  more  prominent; 
the  primary  areola  develops.  Only  very  rarely  may  a  drojilet  of  secretion  be 
squeezed  from  the  nipple.  The  skin  shows  marked  changes:  its  activity  is  increased, 
that  of  the  sebaceous  glands  particularly,  so  that  not  infrequently  comedones  ami 
acne  result;  in  brunets  the  pigmentation  deepens,  the  hair  takes  on  more  luxuriant 
growth,  and  it  also  develops  on  the  mons  pubis  and  axilUe;  strite— fine  fines— 
sometimes  appear  on  the  thighs,  and  especially  on  the  ])reasts.  These  striir  are 
due  to  stretching  of  the  skin,  the  connective-tissue  fibers  arranging  themselves  ni 
parallel  lines,  some  of  them  tearing.     They  at  first  appear  as  purplish  lines,  but 


2  PHYSIOLOGY    OF    PREGNANCY 

after  several  years  turn  a  silvery  white.  The  external  genitalia  grow  larger,  darker, 
more  vascular,  have  more  secretion,  and  emit  a  faint  characteristic  odor.  The 
th>Toid  enlarges,  the  larynx  changes,  especially  in  the  male.  In  the  female  the 
voice  also  is  altered,  becoming  fuller,  lower  in  scale,  and  more  melodious.  In 
brunets  the  tendency  is  toward  a  contralto;   in  blondes,  toward  a  soprano,  range. 

The  mind  undergoes  alteration  in  its  three  parts — the  will,  the  intellect,  and 
the  emotions.  The  will,  especially  during  the  change,  becomes  uncertain,  and  the 
girl  loses  to  a  good  extent  her  control  over  it.  Hysteric  manifestations  are  quite 
common.  The  intellect  broadens;  new  perceptions  give  a  grander  conception  of 
life.  The  girl  feels  that  a  great  transformation  is  taking  place  in  her  being,  and 
the  pride  of  womanhood  and  of  anticipated  wife-  and  motherhood  swells  in  her. 
The  emotions  during  the  period  of  change  also  become  unstable:  the  girl  laughs 
and  cries  often  without  reason,  is  happy,  ga}-,  or  sad  and  melancholy  without 
cause.  One  must  watch  these  manifestations — they  may  exceed  the  normal.  The 
inclination  toward  the  male  increases,  while  at  the  same  time  a  sense  of  modesty 
develops. 

This  transformation  is  the  outward  expression  of  the  changes  occurring  in 
the  internal  organs  of  generation.  The  uterus  is  developing  rapidl}'.  The  vagina 
lengthens  and  becomes  rugous,  the  tubes  grow  longer,  the  ovaries  take  on  a  special 
activity,  ova  develop,  the  Graafian  follicles  enlarge — in  short,  ovulation  begins. 
With  ovulation  comes  the  ability  to  reproduce,  but  the  girl  at  puberty  is  unfit  to 
bring  forth  children.  Cases  are  on  record  where  girls  of  ten  and  even  of  nine  years 
bore  children,  the  one  reported  Ijy  Bodd  weighing  3500  giii.  Plato  set  twenty 
years  as  the  best  age  for  the  first  child,  and  Wernich,  from  a  study  of  the  develop- 
ment of  the  children  of  young  women,  decided  on  the  age  of  twenty-three  as  the 
best.  At  this  time  also  the  pelvis  has  achieved  its  full  development;  the  bones 
are  still  somewhat  elastic,  the  joints  supple;  the  coccyx,  particularly,  can  be  pressed 
back,  and  the  pelvic  genital  tract  is  soft  and  elastic. 

The  most  important  sign  of  the  advent  of  puberty  is  the  appearance  of  the 
menses,  or  menstruation.  This  is  a  flow  of  blood  of  several  days'  duration,  recur- 
ring every  four  weeks,  attended  by  local  symptoms  referable  to  the  genitalia  and 
general  symptoms.  This  phenomenon,  again,  is  dependent  upon  or  related 
to  the  changes  going  on  in  the  ovaries,  called  ovulation.  Therefore,  pul)erty  is 
marked  by  the  inauguration  of  two  new  functions, — ovulation  and  menstruation, — 
each  of  which  will  now  be  considered. 


OVULATION 

Ovulation  is  that  process  by  which  an  ovum  ripens  and  is  extruded  from  the 
ovary — that  is,  it  is  the  maturation  of  the  ovum  or  egg  and  expulsion  of  same 
from  the  ovary. 

The  ovary  is  a  densely  filjrous  little  organ,  situated  in  the  pelvis  on  the  posterior  surface  of 
the  broad  ligament,  in  a  shallow  pouch — the  "fossa  ovarica."  It  is  39  mm.  long,  19  mm.  wide, 
and  8  to  13  mm.  thick,  and  weighs  about  5  gm.  The  right  is  usually  larger  than  the  left,  and  is 
more  liable  to  disease,  because  of  the  proximity  of  the  appendix. 

The  organ  is  shaped  like  a  large  almond,  being  attached  to  the  broad  ligament  by  two  layers 
of  the  peritoneum,  between  which  the  vessels  and  nerves  enter  its  substance.  The  outer  end  is 
attached  by  one  of  the  fimbria?  of  the  Fallopian  tube  to  the  tube.  The  ovary  was  first  mentioned 
by  Herophilus  (Alexandria,  300  b.  c),  and  received  its  name  from  Steno,  in  the  seventeenth  cen- 
tury A.  D.  (Fasbender).  The  ovaries  of  different  women  vary  much  in  size  without  apparently 
any  relation  to  fertility.  At  birth  the  ovary  is  relatively  quite  large.  Its  growtli  up  to  maturity 
is  caused  by  the  formation  of  connective  tissue,  vessels,  and  the  enlargement  of  existing  primordial 
follicles.  Corpora  albicantia  and  a  corpus  luteum  were  found  in  the  ovaries  of  new-born  and  very 
young  children  by  Runge.  Many  ova  are  destroyed  before  pul)erty  by  the  constriction  of  the 
fibrous  tissue.  After  the  menopause  the  ovary  shrinks,  and  in  old  women  may  be  as  small  as  a 
navy  bean.  Accessory  ovaries  have  been  found  on  the  broad  ligaments,  and  are  proliably  the 
result  of  faulty  development,  not  of  fetal  inflammation!  A  third  ovary  and  corresponding  tube 
have  been  found,  which  is  interesting  from  several  clinical  and  medicolegal  points  of  view.     The 


PUBERTY,    OVULATION,    AND    MENSTRUATION 


ovary  is  covered  by  a  layer  of  low  columnar,  lusterless  epithelium,  called  the  germinal  epithelium, 
under  which  is  the  tough  tunica  alhuginea.  Beneath  this  are  small  unripe  ova,  while  deeper  down 
are  larger  ova  in  the  process  of  ripening.  These  ova  are  surrounded  by  stroma,  made  up  of  elastic 
fibers,  yellow  and  white,  and  unstriped  muscular  fibers,  all  three  most  abundant  at  the  hilum. 
The  blood-supply  is  abundant,  and  numerous  fine  nerves  form  networks  around  the  foUicIes. 

The  formation  of  ova  begins  early  in  fetal  life.  On  the  posterior  wall  of  the  abdomen  of  the 
embryo,  to  the  inside  of  the  Wolffian  bodies,  two  Hght  streaks  f)f  cclom-peritoneai  epithelium 
appear.  They  are  supported  by  connective  tissue,  and  are  tiie  primary  structures  of  the  future 
ovary  or  testicle.     In  the  somewhat  proliferated  peritoneal  epithelium  (germinal  epithelium  of

vesicular  nucleus,  the  primordial  eggs,  or  ova.  These  may  develop  into  primordial  seminal  cells 
if  the  fetus  is  a  male.  The  germinal  epithelium  proliferates  actively,  as  do  also  the  primordial 
ova,  and  dips  down  into  the  stroma  of  the  ovary,  carrying  with  it  the  ova.  These  groups  of  cells 
are  called  "egg  balls,"  or  the  Pfliiger  "ovarian  tubes."  The  connective  tissue  surrounding  these 
columns  of  epithelial  cells  grows  in  such  a  manner  that  masses  of  germinal  epithelium  containing 
one  or  two  primordial  ova  are  split  off,  until  finally  the  ovaryis  forme<l  completely  of  such  "prim- 
ordial follicles"  and  connective-tissue  stroma.  The  primordial  follicles  develop  into  the  larger 
structures,  which  de  Graaf  discovered  in  1672  and  have  been  nanied  after  him.  The  ova  are 
nearly  all  completed  during  fetal  life;   perhaps  some  are  formed  during  the  first  few  years  of  life.

The  ovarv  of  the  new-born  infant  contains  ovocytes  of  a  number  variously  estmiate«l  at  from  36,000 
to  200.000.  These  are  dosclv  arranged  in  the  periphery  of  the  ovary,  while  toward  the  hihun  are  a 
few  follicles  in  further  advancement;  The  main  function  of  the  ovary  is  to  mature  and  tlischarge 
the  ova  lying  in  the  Graafian  follicles.  Other  functions  are  ascribed  to  the  ovary,  but  their  dis- 
cussion will  be  made  later.  ■  •      i 

When  a  follicle  begins  to  ripen.— and  one  lying  near  the  hihun  usually  undergoes  this  change, 
—it  sinks  toward  the  center  of  the  ovarv.  The  follicle  epithelium  undergoes  a  rapid  prohferation ; 
some  of  the  central  cells  vacuolate  and"dis.solve,  a  fluid  appears  in  the  center  of  the  mass  of  cells,

changes  destined  to  prepare  it  for  the  reception  of  the  male  element  are  going  on  in  the  o^1^m  em- 
bedded in  the  discus  proligerus.  The  ovum  is  a  t^^pical  cell,  and  consists  of  a  cell-wall,  protoplasm, 
deutoplasm,  or  yolk,  which  are  later  in  the  development,  and  a  nucleus,  or  germinal  vesicle,  with 
a  nucleolus  or  germinal  spot.  This  has  ameboid  motion.  During  the  latter  period  of  the  ripening 
the  nucleus  nears  the  surface  and  undergoes  an  unequal  karyokinesis.  After  the  formation  of  the 
chromosome  spindle  one-half  is  extruded  as  a  small  globule,  the  first  polar  cell,  and  comes  to  he 
under  the  zona  pcllucida.  The  remaining  half  of  the  spindle  divides  again,  grows  to  a  complete 
spindle,  splits,  and  the  process  of  extrusion  of  the  second  polar  globule  is  completed  (Fig.  9). 
The  polar  globules  were  discovered  by  Robin,  a  French  histologist,  in  1821-1825.  The  formation 
of  the  polar  globule  has  never  been  observed  in  the  human  ovum,  but  it  occurs  in  all  animals.

The  gerrnmal  vesicle  now  rests,  and  is  called  the  female  pronucleus.  It  is  smaller  than  the  germi- 
nal vesicle  was,  has  a  smaller  germinal  spot  and  no  nuclear  memlarane.  The  reasons  ach'anced 
lor  the  foi-mation  and  extrusion  of  the  polar  globules  are,  first,  that  it  is  an  excretion,  second,  that 
It  leaves  the  ovum  in  an  incomplete  state,  requiring  the  male  element  to  make  it  fertile,  otherwise 
parthenogenesis  might  occur;  third  (Hertwig),  that  the  process  is  necessary  to  reduce  the  number 
ot  chromosomes  of  th(!  female  nucleus.  A  similar  extrusion  of  polar  globules  is  observed  in  the 
tormation  oi  the  niale  pronucleus,  and  thus  both  male  and  female  germinal  vesicles  are  reduced  to 
halt  nuclei,  which,  when  they  unite  in  conception,  restore  the  original  number  of  chromosomes, 
ihus  the  .size  of  the  germinal  vesicle  remains  constant.  Otherwise  in  repeated  generations  it 
would  grow  too  large  for  its  parent  cell,  the  ovum. 


PUBERTY,  OVULATION,  AND  MENSTRUATION  7 

The  completely  matured  ovmii  as  it  is  ex]3elled  from  the  Graafian  follicle 
(Fig.  10)  is  just  visible  to  the  eye  as  a  fine  white  point,  measuring,  naked, 
I  millimeter  in  diameter.  It  is  surrounded  by  100  or  more  epithelial  cells  de- 
rived from  the  membrana  granulosa,  arranged  radially  around  the  ovum,  and 
called  the  corona  radiata;  inside  this  is  the  egg-shell,  oolenmia,  zona  pellucida, 
a  thick  membrane  with  radial  fibrillations,  not  constant  in  all  animals;  next  comes 
a  space,  Avhicli  also  is  not  constant,  the  perivitelline  space  (Xagel),  and  may  be 
only  an  optical  elTect,  or  it  may  occur  after  the  extrusion  of  the  polar  globules; 
the  vitellus,  or  yolk,  with  a  l)road  clear  zone  of  protoplasm  and  a  large  central 
zone  of  dark,  coarsely  granular  deutoplasm;  the  female  pronucleus^which  was 
the  germinal  vesicle;  the  germinal  si)ot;  and  several  small  dark  granules  in 
the  nucleus. 

The  expulsion  of  the  ovum  takes  place  wlien  the  Graafian  fcjllicle  burst.s,  the 
former  having  already  been  loosened  from  its  bed  in  the  cunmlus  ovigerus  by

vacuolization  of  the  cells  of  the  membrana  granulosa.     The  ovum  fimls  its  way 
to  the  tube,  there  to  await  fcrlinzation  by  the  male  element. 

The  Formation  of  the  Corpus  Luteum. — After  the  escape  of  the  ovum  and 
l)art  of  the  li(iuor  folliculi  out  of  th(>  Graafian  follicle  the  walls  of  the  latter  collapse, 
and  any  space  remaining  fills  with  blood  from  ruptured  vessels  of  the  tunica  proi)ria. 
It  is  probable  that  a  little  blood  flows  also  into  the  peritoneal  cavity.  Rarely, 
enough  may  be  lost  to  l)e  of  clinical  importance — even  fatal.  Most  authors  l^elieve 
that  the  membrana  granulosa  disappears,  and  the  cavity  is  invaded  by  connective- 
tissue  cells  from  the  theca,  containing  a  yellow,  refracting  jiigment — lutein.  Bisch- 
off  ])elieved  the  lutein  cells  are  modified  ejiithelial  cells  from  the  membrana 
granulosa,  and  the  latest  work  proves  he  was  correct.  There  is  a  very  active 
production  of  lutein  cells,  which  come  to  lie  in  festoons  around  the  central  blood- 
clot.  The  small  collapsed  follicle  grows  in  the  first  two  weeks  to  the  size  of  a 
l)ean,  and  sliows  the  irregular  yellow  outline  of  lutein  cells  around  the  red  blood- 
clot.      Fibrous  tissue  grows  into  the  lutein  mass  and  the  blood-clot  from  the  i)eriph-

corpus  luteum,  as  it  is  called,  is  the  size  of  a  kidney-bean.  Now  retrogression 
occurs,  the  connective  tissue  replacing  the  lutein  cells,  whereby  the  yellow  color  is

changed  to  silvery  white,  the  corpus  albicans  (Fig.  13) ;    after  several  weeks  more 
the  corpus  luteum  is  represented  only  by  a  small  retracted  scar. 

If  pregnancy  supervenes  on  this  ovulation,  the  great  vascularity  of  the  parts, 
or  some  other  factor  whose  nature  cannot  be  surmised,  causes  an  excessive  growth 
of  the  corpus  luteum.  The  histologic  changes  are  the  same  as  described,  but  they 
are  greater  and  prolonged.    The  full  growth  is  attained  at  the  thirteenth  week,  when

size  until  toward  the  end  of  pregnancy,  when  regressive  changes  begin  which  are 
completed  several  months  after  delivery.  The  large  corpus  luteum  of  pregnancy 
is  sometimes  called  a  true  corpus  luteum.     The  small  cor])us  luteum  of  menstru-

ation  is  sometimes  called  a  false  corpus  luteum.  It  is  usually  possible  to  distin- 
guish one  from  the  other,  but,  as  Hirst  has  shown,  in  the  ovaries  of  two  virgins  in 
which  the  corpus  luteum  of  menstruation  was  almost  exactly  like  a  corj^us  luteum 
of  pregnancy,  one  cannot  always  be  certain.     In  old  women  with  poor  circulation,

according  to  AVilliams,  and  in  others  with  ovarian  affections,  the  corpus  luteum 
presents  pathologic  conditions.  Some  Graafian  follicles  do  not  rupture  after  they 
are  ripe,  and  a  process  of  pseudo-corpus  luteum  formation  occurs  also  in  them.

mucosa  so  that  it  reacts  to  the  stimulation  of  the  ovum  (or,  indeed,  any  foreign 
l^ody),  with  the  production  of  exuberant  decidua  or  maternal  placenta.  Loeb 
also  believes  that  the  same  ferment  inhibits  ovulation  during  pregnancy,  though 


PUBERTY,  OVULATION,  AND  MENSTRUATION

clinical  cxporionce  shows  that  this  is  not  invariable.  It  sccnis  that  tiic  nidation 
and  stability  of  the  pregnancy  are  dependent  on  the  corpus  luteum,  because  removal 
of  the  same  in  the  early  months  usually  causes  abortion.  Later,  pregnancy  is 
less  likely  to  be  interrupted — a  point  of  practical  importance.  The  breast  changes 
in  pregnancy  are  also  due  to  this  ferment  in  the  blood. 

The  ovary  has  other  functions.  The  mighty  changes  in  the  whole  system  of 
the  female  occurring  at  puberty  are  ascribable  to  influences  emanating  from  the 
ovary.  Whether  this  influence  is  spread  partlj'  by  means  of  the  nervous  system, 
or  Avhether  the  newer  theories  of  Halban  and  Frankel  (loc.  cit.)  explain  the  changes, 
is  not  yet  decided.  Halban  transplanted  ovaries  to  various  portions  of  the  body, 
thus  destroj'ing  all  nerve  connections,  and  decided  that  the  puberty  and  men.strual 
changes  in  the  breasts  are  due  to  chemical  substances  prepared  in  the  ovary  and 
set  free  in  the  blood.  That  the  ovary  has  an  internal  secretion  is  now  doubted 
by  few.  The  symptoms  of  the  menopause,  especially  the  exaggerated  phenomena 
in  the  nervous  system  and  in  metabolism,  observed  so  often  after  ca.stration,  and 
the  occasional  relief  obtained  by  the  administration  of  ovarian  extract,  justify 
this  assumption.  Ovarian  extract  reduces  the  coagulability  of  the  blood  and 
lowers  blood-pressure.  In  animals  the  presence  of  an  "interstitial  gland"  in  the 
ovary  has  been  demonstrated.  The  ovarj'  has  an  influence  on  the  formation  of 
bone,  e.  g.,  osteomalacia,  also  on  the  thyroid.  The  most  important  function 
ascribed  to  the  ovary,  next  to  ovulation,  is  the  superinduction  of  menstruation. 

MENSTRUATION 

^Menstruation,  also  called  the  menses,  the  ''periods,"  "catamenia."  "monthly 
sickness,"  "the  monthlies,"  "cleansing,"  "the  flowers,"  may  be  defined  as  a  periodic 
flow  of  blood  from  the  genitals,  recurring  every  four  weeks,  accompanied  by  general

symptoms  of  malaise,  nervous  manifestations,  etc.,  and  local  sj-mptoms  of  pelvic 
congestion.  This  phenomenon  occurs  during  the  normal  reproductive  period  of 
women,  the  menacmc  (Kisch).  which  l)egins  with  puberty,  and  continues  up  to 
about  forty-five  years.  At  this  age,  among  other  changes,  the  i)eriods  cease  and 
the  menopause,  the  climacteric,  or  the  "change  of  life,"  takes  place.

PUBERTY,    OVULATION,    AND    MENSTRUATION  13 

The  menstrual  flow  begins  us  a  whitish  discharge,  hut  soon  becomes  l^loody, 
and  contains  red  and  white  blood-corpuscles,  degenerated,  ciliated,  and  columnar 
epithelium,  vaginal  and  uterine  secretions,  and  many  microorganisms,  some  of  them 
pathogenic. 

The  Anatomy. — When  the  uterus  is  quiescent,  that  is,  between  two  periods,  the  mucous 
membrane  is  tliin  (1  to  2  mm.),  pale,  and  smooth,  the  glands  are  small,  the  .secretion  scant,  the 
arteries  and  veins  not  prominent,  but  on  the  injected  specimen  they  are  seen  to  be  numerous. 
Especially  thick  is  the  capillary  network  just  under  the  epithelium  and  around  the  glands.  The 
cylindric  ciUated  epitlielium  is  continued  into  the  glands.  It  is  higher  in  the  gland  lumina.  The 
connective  tissue  around  the  glantis  contains  many  large  round-cells  with  large  nuclei  (Fig.  17). 
About  ten  days  before  the  appearance;  of  the  menses  the  uterus  becomes  congested,  enlarges, 
grows  softer,  the  endometrium  thickens  to  .5  or  even  7  mm.,  the  connective  tissue  is  infiltrated  with 
serum,  the  capillaries  are  filled  to  bursting,  the  epithehal  cells  enlarge,  and  the  larg(!  round-cells 
in  the  connective  tissue  are  found  to  be  proliferating  rapidly.  The  glands  increase  in  length, 
change  form,  become  complex, 
and    are    filled    with  secretion.

studies  have  provetl  tliat  really  (Ance8tru.m). 

very  few  epithelial  cells  are  cast 
off  in  normal  menstruation.     In 

pathologic  cases  tlie  superficial  layers  may  exfoliate,  and  these  women  often  have  ilysnu-norrhea 
and  are  sterile. 

After  a  few  days  regression  begins,  the  interglandular  cells  in  the  area  of  greatest  congestion 
undergo  a  fatty  degeneration,  as  do  also  a  few  of  the  epithelial  cells.  The  remaining  portions  are 
gradually  regenerated.  The  congestion  subsides,  the  surface  becomes  anemic,  the  exudeil  serum 
and  the  small  hematomata  are  absorbed,  the  endometrium  becomes  thinner,  the  cavity  of  the 
uterus  gradually  reduces  in  size,  and  the  organ  comes  to  rest,  the  process  reciuiring  about  eight 
days.  This  period  of  rest  lasts  onlv  a  few  days,  because  the  preparation  for  the  next  menstruation 
begins  again.  The  changes  described  are  called  the  menstrual  cycle,  and  this  cycle  is  repeated 
every  four  weeks  during  the  menacme,  unless  interrupted  by  pretrnancy.  lactation,  or  some  patho- 
logic condition. 

The  caus(>  of  the  phenomenon  of  men.struation  is  still  unknown.  The  most 
generally  accepted  theory  is  that  an  influence  of  some  sort  emanates  from  the  ovarj' 
during  ovulation,  and,  reaching  the  uterus,  causes  a  severe  congestion  and  the 
changes  above  described   (Bischoff,   1844).     Pfluger  believed  that   the  Graafian 


14  PHYSIOLOGY   OF   PREGNANCY 

follicle,  by  its  gradual  enlargement,  exerted  a  compression  on  the  nerves  in  the 
stroma  of  the  ovary;  this  irritation  of  the  nerves  was  at  first  mild,  but  periodically 
reached  an  acme  of  intensity  which  caused  a  congestion  of  the  blood-vessels  of  the 
pelvis;  that  this  hastened  the  maturation  of  the  ovum  and  the  bursting  of  the 
Graafian  follicle,  on  the  one  hand,  and,  on  the  other,  caused  the  changes  in  the 
endometrium  which  were  described  as  the  anatomic  basis  of  menstruation.  There 
are  many  arguments  for  the  theory  that  ovulation  causes  menstruation— (1)  In 
animals,  copulation  during  heat  causes  conception,  therefore  ovulation  must  occur. 
Heat  in  animals  (oestrus)  is  analogous  to  menstruation.  (2)  At  operations  and  at 
postmortems  on  women  djang  during  the  menstrual  period  fresh  corpora  lutea  or 
fully  developed  follicles  are  almost  always  found.  Bimanual  examination  in  favor- 
able cases  will  often  show  an  enlargement  of  one  ovary,  and  one  may  feel  the 

Graafian  follicle  burst  under 
the  pressure  of  the  fingers. 
In    an   ovarian   hernia  the 
periodic     swelling     of    the 
ovary  has  been    observed. 
(3)  Hyrtl  descril^es  the  case 
of    a   girl    who    died    after 
ight    periods,     where     he 
found  four  corpora  lutea  in 
each  ovary.      (4)    Removal 
of  the  ovaries  causes  cessa- 
tion of  the  menses,  and  in 
cases  of  congenital  absence 
of  the  ovaries  there  are  no 
menses.      (5)     There    must

Ovulation  occurs  before  the 
birth  of  the  child,  during  childhood,  and  after  menstruation  ceases.  Pregnancies  have 
occurred  before  puberty  (see  p.  2) — the  child  may  have  "fruit  before  flowers"  (De 
la  Motte) .  Conception  has  occurred  during  the  prolonged  absence  of  the  menses,  dur- 
ing the  amenorrhea  of  lactation,  and  also  after  the  menopause.  (3)  In  some  animals 
ovulation  occurs  long  before  heat.  (4)  Copulation  has  an  influence  on  ovulation,  as  is 
proved  by  the  fact  that  puberty  occurs  earlier  when  coitus  is  performed  early,  as  in  the 
countries  of  early  marriages ;  (2)  in  rabbits  it  has  l^een  sho-s\Ti  that  copulation  hastens 
the  rupture  of  the  Graafian  follicle,  and  (3)  certain  tortoises  cohabit  two  years  before 
the  eggs  are  fertile.  Nevertheless,  ovulation  is  l)y  no  means  dependent  on  coitus, 
as  virgins  perform  the  function  regularly.  Experiments  on  animals  have  been  made 
by  Frankel,  Bouin,  Ancel,  Loeb,  and  others  to  determine  this  relation.  All  that 
can  reasonably  be  deduced  from  a  study  of  the  facts  is  that  there  is  a  strong  con- 


PUBERTY,    OVULATIOX,    AND    MENSTRUATION  15 

nection  between  the  functions  of  the  ovary  and  of  the  uterus;  tiiat  the  impulses 
leave  the  ovary  and  affect  the  uterus;  that  the  phenomenon  of  menstruation  is, 
probably,  the  result  of  the  stimulation  of  ovulation,  and  that,  while  ovulation  may 
occur  at  any  time,  the  monthly  ovulation  is  the  usual  one,  and  affects  the  uterus, 
therefore  monthly  also. 

It  is  not  necessary  that  the  Graafian  follicle  rupture  to  pnxluce  menstruation. 
The  development  and  regression  alone  suffice.  How  the  influence  of  the  ovary  is 
transmitted  to  the  uterus  is  not  known.  Pfliiger  believed  the  stretching  of  the 
ovary  caused  by  the  growing  (Iraafian  follicle  irritated  the  nerves  of  the  ovary  and 
thus  the  reflex  was  elicited.  Strassman  injected  fluids  into  the  ovaries  of  animals 
and  produced  evidence  of  heat.  Probably  it  is  not  via  the  nervous  system,  though 
nerves  have  been  demonstrated  even  in  the  membrana  granulosa  (Mandl).  Many 
experiments  and  clinical  ob- 
servations point  to  the  ac-  ...„.  vjV/.  -»•.<;'  O"^  ••  U44.-^^

Haiban  has  sought  to  prov( 
that  the  internal  secretion  of 
the  ovaries  causes  the  men- 
struation. He  transplanted 
ovaries  to  distant  parts  of 
the  body  of  monkeys,  and 
a  sort  of  pseudo-menstrua- 
tion continued.  Then  he 
removed  the  ovaries  and

plete literature.  Trans- 
planted portions  of  the

the  stimulation  of  preg- 
nancy (Pfister).  Perhaps 
the  internal  secretion  of  the

We  know,  for  example,  that 

certain  ferments  are  produced  at  one  point  of  the  intestinal  tract,  and  are  carried 

by  the  blood-stream  to  another  ix)int,  and  there  awaken  the  action  of  the  intestinal 

glands. 

Most  recently  the  hypothesis  has  been  advanced  that  menstruation  is  caused 
by  cyclic  biochemical  changes  in  the  blood,  having  to  do  with  the  metabolism 
of  calcium. 

The  object  of  monstruation  ha.'^  also  p:iven  rise  to  much  theorizing-  The  oldc-^t  notion  re- 
garding the  menstrual  discharge  is  that  it  is  the  result  of  a  general  plethora.  The  woman  is  en- 
dowed with  greater  blood-making  powers,  lus  she  must  nourish  the  fetus  also.  If  slie  remains 
sterile,  there  is  no  need  for  this  extra  blood,  and  it  is  thus  gotten  rid  of.  While  by  no  means  accept- 
ing this  theory,  it  is  interesting  to  note  that  in  poorly  nourished  girls,  or  those  of  a  tuberculou." 
type,  nature  withholds  the  menses  for  no  other  reason,  obvioiisly,  than  to  save  the  organism  this 
useless  waste  of  Ijlood.     Another  theory,  little  less  old,  is  that  of  a  purificatiou.     Even  yet  by 


16  PHYSIOLOGY    OF    PREGNANCY 

some  races  women,  while  menstruating,  are  regarded  as  unclean.  The  substances  which  were 
passed  in  the  monthlj-  discharges  were  supposed  to  be  poisons.  Recentlj^  a  southern  writer  said 
that  cases  of  retention  of  the  menses  could  result  in  headache,  neuralgia,  and  rheumatic  pains, 
even  epilepsy.  In  Germany  the  term  "monathche  Reinigung,"  "monthly  cleansing,"  is  still  used. 
Schmoulker  and  Ivieffer  declared  that  the  menstrual  blood  is  an  excretion,  relieving  thus  a  toxemia. 
Charrin  proved  that  the  woman's  blood  is  more  toxic  before  and  during  menstruation.  Turenne 
explained  the  toxemia  of  pregnancy  as  a  menorrhemia,  and  administered  ovarian  extract  as  a 
remedy,  but  has  no  followers. 

Pfliiger  said  the  hemorrhage  prepared  the  mucous  membrane  of  the  uterus  in  the  manner  of 
an  inoculation  surface  for  the  reception  of  the  egg.  Power  said:  "A  woman  menstruates  because 
she  does  not  conceive."  The  mucous  membrane  is  prepared  each  month  for  the  reception  of  the 
fertiUzed  ovum.  Aveling  called  it  "nest  building."  If  conception  does  not  occur,  the  nest  is  not 
needed — the  mucous  membrane  undergoes  regressive  changes  under  the  clinical  picture  of  men- 
struation. We  now  know  that  the  uterus  is  sensitized  for  the  o\aim  by  the  ferment  from  the  corpus 
luteum. 

Tubal  Menstruation. — There  are  reasons  for  believing  that  the  Fallopian  tubes 
also  take  some  part  in  menstruation — first,  because  tubes  fastened  in  the  abdominal 
wall  often  have  periodic  bloody  discharges;  second,  cases  of  hematosalpinx  point 
to  this  action;  and  third,  a  decidua  menstrualis  has  been  found  in  the  tube  (Arendt). 
One  might  argue  against  this  supposition  that  the  blood  regurgitated  from  the 
uterus;  that  in  all  these  cases  the  tube  was  diseased,  which  holds  true  for  the 
first  two  cases,  at  all  events.  The  mucous  membrane  of  the  tubes  may  undergo 
changes  similar  to  those  of  the  endometrium  without  the  escape  of  blood,  as  one 
also  observes  a  marked  congestion  of  the  cervix,  vagina,  and  vulva,  with  increased 
secretion  of  the  glands,  during  menstruation. 


THE  CLINICAL  ASPECTS  OF  MENSTRUATION 

Time  of  Appearance. — In  aljout  2  per  cent,  of  new-born  girls  there  appears  a 
blood^y,  mucoid  discharge  from  the  vagina,  which  lasts  one  to  four  days.  This  is 
called  pseudo-menses,  usually  indicates  nothing  pathologic,  and  requires  no  treat- 
ment unless  prolonged  and  profuse.  Bayer  ascribed'  it  to  the  ovarian  influence  of  the 
mother  transmitted  as  an  internal  secretion  to  the  fetus  by  way  of  the  placenta.  It 
may  be  due  to  ovulation  going  on  at  the  time  of  birth  in  the  mother,  or  even  in  the 
child.  Almost  alwa^'s  this  pseudo-menses  does  not  recur,  but  cases  of  precocious 
menstruation  are  on  record.  Plumb  reports  the  case  of  a  nine-pound  girl  with  genitals 
like  a  fifteen-year-old,  whose  periods  began  six  weeks  after  birth,  and  continued  every 
six  weeks  thereafter.  Cases  of  the  menses  beginning  in  the  third  and  fifth  month, 
with  development  of  the  genitalia  and  with  hair  on  the  pubis  before  the  sixth  year, 
are  on  record.  This  precocit^y  is  sometimes  inherited.  Often,  however,  it  is  the 
evidence  of  disease.  The  author  saw  very  profuse  pseudo-menses  in  two  infants 
that  died  of  cerebral  hemorrhage.  Several  cases  of  precocious  menstruation  had 
hydrocephalus,  sarcoma  of  the  ovary,  tuberculosis,  or  other  disease. 

The  time  of  the  advent  of  puberty  and,  with  it,  the  menses,  varies  according 
to  climate,  environment,  race,  heredity,  condition  of  life,  and  type  of  person. 
Warm  climate  seems  to  bring  on  early  menstruation :  the  Hindus  having  the  menses 
at  twelve  years,  and  English  women  living  in  India  are  affected  likewise.  In 
Greenland  puberty  begins  from  the  seventeenth  to  the  twenty-third  j'ear,  and  some 
of  the  Eskimos  menstruate  onh'  in  summer. 

Races  show  marked  variations.  The  Aryans  and  Slavs  menstruate  late,  the 
Jews  and  most  Orientals  early.  Brunets  and  red-haired  girls  menstruate  early; 
blonds,  late  (Kisch).  Environment  exerts  a  strong  influence.  The  highly  strung 
city-bred  girl  has  early  periods,  the  country  girl,  later;  the  poor  overworked  factory 
girl,  later;  the  girl  reared  in  luxury,  who  has  dances,  sees  plays,  reads  novels,  earl}-. 
Chlorotic  and  tuberculous  girls,  by  a  wise  conservatism  of  nature,  do  not  menstru- 
ate or  do  so  toward  the  twentieth  year.  Indeed,  the  late  or  scant  appearance  of  the 
flow  should  warn  to  a  careful  examination  of  the  patient. 


PUBERTY,    OVULATION,    AND    MENSTRUATION  17 

If  the  mother  menstruated  early,  the  daughter  may  also.  The  same  is  true 
of  the  cessation  of  the  periods. 

Symptoms. — At  the  onset  of  the  menses  the  woman  usually  has  symptoms 
referal)le  to  the  genitaha  and  general  symptoms, -which  are  called  menstrual  molim- 
ina.  Headache,  throljbing  in  character,  malaise,  and  a  feeling  of  lassitude, 
neuralgias,  especially  of  the  face,  chilliness,  flashes  of  heat,  all  these  occur  and  ishow 
the  powerful  effect  of  o^•ulation  on  the  entire  body.  Sexual  desire  is  usually  exag- 
gerated; there  is  increased  sensibility,  both  of  the  skin  and  of  the  mind,  and  in 
those  predisposed,  hysteric  outbreaks  are  common.  The  emunctories  are  more 
active,  and  the  patient  more  likely  to  take  cold  at  this  time.  The  skin  often  emits 
a  slight  odor;  attacks  of  urticaria,  acne,  and  eczema  have  Ijeen  noticed.  The 
eyes  often  have  dark  circles;  occasionally  the  hds  darken  as  well;  hordeolum, 
slight  asthenopia,  muscular  and  neural,  have  been  often  observed  (Berger). 

The  bowels  are  disturbed,  diarrhea  and  tjTnpany  occasionally  occurring,  and 
the  appetite  may  be  capricious.  ^Mild  attacks  of  tonsillitis  are  not  uncommon. 
There  is  pain  in  the  back,  in  the  gi'oins  (ovaries),  sometimes  exaggerated  to  path- 
ologic dysmenorrhea,  irritation  of  the  bladder,  and  slight  polyuria.  The  tempera- 
ture is  raised  a  degree,  the  pulse  is  faster  and  harder,  the  blood-pressure  being 
raised  20  mm.  until  the  bloody  flow  begins.  Then  it  drops  until  the  flow  ceases, 
when  a  slow  rise  is  observed.  The  erjihrocytes  increase  before,  and  diminish 
during,  the  flow.     The  amount  of  urea  excreted  is  decreased,  the  COo  increased. 

The  external  genitalia  are  somewhat  engorged,  darker,  succulent;  the  dis- 
charges from  the  vulva,  vagina,  and  cervix  are  augmented;  indeed,  the  endome- 
trium secretes  freely  only  just  before  and  during  menstruation  (Hirschmann). 
The  cervix  and  vagina  are  more  open;  the  uterus  is  larger  and  softer;  indeed,  the 
whole  pelvis  suffers  from  an  acute  vascular  engorgement.  The  acme  of  the  changes 
is  reached  on  the  first  day,  after  which  the  changes  gradualh'  subside.  The  Ijreasts 
also  enlarge,  become  tender,  and  not  seldom  a  few  drops  of  colostrum  may  be 
squeezed  from  the  nipple.  The  nipples  are  more  erectile  and  darker,  the  findings 
thus  resemljling  those  of  earl}'  pregnancy.  The  thyroid  enlarges  at  puberty,  and 
this  may  be  permanent;  it  also  swells  during  the  period,  but  this  engorgement 
subsides.  A  relation  between  the  ovary  and  the  thyroid  gland  is  apparent  in  more 
than  one  condition. 

The  character  of  the  flow  varies  in  different  women.  It  also  changes  from  day 
to  day.  At  first  it  is  mucoserous,  then  bloody,  then  almost  pure  l)lood,  which  does 
not  coagulate.  The  color  is  dark  maroon,  but  in  chlorotic  girls  it  maj'  be  watery 
or  even  colorless.  It  is  alkaline  in  reaction,  slightly  irritating,  and  has  an  odor 
like  marigold.  This  depends  on  the  constitution  of  the  woman — some  having  a 
fetid  odor — and  the  bacteria  in  the  discharge.  The  menstrual  blood  is  infectious 
for  puerperae.  Clots  normally  arc  not  present.  The  amount  varies  from  four  to 
six  ounces,  but  this,  as  well  as  the  duration  of  the  flow,  is  not  constant  in  the  same 
woman  nor  the  same  in  all  women. 

The  duration  of  the  flow  varies  within  wide  limits,  l)ut  it  usually  lasts  three  to 
seven  daj's.  The  English  and  American  women  flow  three  to  five,  the  French 
five  to  seven,  days.  At  the  Ijeginning  of  puberty  the  flow  is  moderate;  later  more 
profuse  and  prolonged,  especially  after  marriage,  the  result  of  the  physiologic 
stimulation  of  intercourse  or  of  endometritis,  one  of  the  late  effects  of  gonorrhea  or 
childbirth.  Sexual  stimulation  increases  the  flow  and  sometimes  its  frequency. 
Brunets  flow  more  than  blontls;  warm  climates  increase  the  discharge.  The  test 
whether  the  flow  is  normal  or  not  is  the  effect  on  the  woman.  If  she  is  well,  a  short 
flow  or  a  long  flow — even  its  entire  absence — should  give  no  concern. 

Periodicity. — At  least  71  per  cent,  of  women  menstruate  ever>'  twenty-eight 
dajjs,  and  tlie  majority  during  the  new  moon.  If  the  flow  starts  a  day  earlier  or 
later,  it  is  of  no  importance.    There  are  several  types,  as  a  twenty-eight-day  U-pe 


18 


PHYSIOLOGY   OF   PREGNANCY 


(71  per  cent.),  a  twenty-one-day  tj-pe  (2  per  cent.),  a  thirtj^-day  type  (14  per  cent.), 
a  twenty-seven-day  type  (1  per  cent.),  though  some  women  flow  every  six  weeks 
and  are  healthy.  If  one  studies  the  life  of  woman  carefully,  clinicall}^,  and  with 
the  help  of  physical  methods,  one  can  determine  an  el)b  and  flow  in  her  activities, 
mental  and  physical.  This  cyclic  movement,  described  l^y  Goodman  in  1878,  or 
"Wellenbewegung,"  or  periodicity,  reaches  the  highest  point  of  its  tide  just  before 
the  appearance  of  the  menses.  Fig.  20,  from  v.  Ott,  shows  this  graphically.  The 
functions  of  the  body,  reflex  excitability,  the  pulse,  the  blood-pressure,  pulmon- 
ary capacity,  heat  radiation,  temperature,  excretion  of  urea,  muscular  power,  all 
increase  according  to  the  line  in  the  figure,  up  to  within  a  daj'  of  the  menses;  on 
this  day  there  is  an  abrupt  regression,  then  a  gradual  recovery,  which  rebounds 
and  drops  to  normal  about  the  seventh  day  after  menstruation  (Reinl).  This 
periodicity  is  slightly  manifest  in  the  male,  and  recurs  in  five  to  six  weeks'  intervals. 
Perhaps  it  is  the  external  evidence  of  the  formation  of  spermatozoids. 

The  menopause,  the  "change  of  life,"  "the  climacteric,"  "die  Wechseljahre," 
"losing  the  periods,"  takes  place  between  the  fortieth  and  the  fiftieth  year.  Thus 
the  average  lengih  of  the  reproductive  era  of  a  woman's  life  is  about  thirty  years.

Statistics  prove  this  for  nearl}'  all  countries.  The  extremes  are  six  to  fortj^-six 
years.  Krieger  collected  2291  cases,  and  found  the  menses  ceased  in  12  per  cent, 
of  cases  between  the  thirty-sixth  and  the  fortieth  year;  in  26  per  cent,  between  the 
forty-first  and  the  forty-fifth  years;  in  41  per  cent,  of  the  cases  between  the  forty- 
fifth  and  fiftieth  years,  and  15  per  cent,  of  the  cases  from  the  fiftieth  to  the  fifty- 
fifth  years,  the  balance,  7  per  cent.,  being  distributed  before  the  thirty-fifth  and 
after  the  fifty-fifth  years. 

The  climacteric  occurs  earlier  in  sterile  women,  in  cold  than  in  warm  countries, 
in  the  poor  than  in  the  rich,  in  black  than  in  white  women.  If  puberty  is  early, 
menopause  is  late,  the  sexual  function  being  strongly  developed;  but  if  the  repro- 
ductive organs  are  overused  or  diseased,  the  menopause  may  be  earlier.  The  menses 
may  return  after  having  ceased.  Meissner  (quoted  by  Krieger,  loc.  cit.)  tells  of 
this  case:  Menses  at  twenty;  first  child  at  forty-seven;  up  to  sixty  years,  7 
children;  cessation  of  the  menses;  seventy-five  to  ninety-eight  years,  regular 
periods;  five  years  absent;  one  hundred  and  four  years,  menstruation  again;  end  not 
known.  Charpentier,  quoted  l)y  Parvin,  reports  a  case  of  menses  ceasing  at  forty- 
eight,  beginning  again  at  sixty,  then  continuing  for  two  years.     In  all  such  cases 


.      PUBERTY,    OVULATION,    AND    MENSTRUATION  19 

one  should  search  carefully  for  pathologic  conditions,  as  fibroid,  cancer,  atheroma, 
senile  endometritis,  etc.  Pregnancy  has  occurred  after  the  menopause.  In  addi- 
tion to  the  above,  Renaudin  reports  a  case  where,  twelve  years  after  the  menses 
ceased,  a  living  child  was  born.  Kennedy  reports  the  case  of  a  woman  who  had 
five  labors  and  one  abortion  after  the  fiftieth  year. 

Usually  the  advent  of  the  menopause  is  announced  by  alteration,  diminution, 
or  irregularity  of  the  flow.  The  amount  of  blood  diminishes,  mucus  or  serum 
replacing  it.  When  the  flow  becomes  more  profuse  than  usual,  attention  should 
be  directed  more  closely  to  the  woman.  The  cessation  of  the  menses,  especially 
in  nulliparae,  is  often  attended  by  nervous  symptoms,  such  as  loss  of  vasomotor 
control,  flushings  of  the  face  and  the  body,  flashes  of  heat  and  cold,  trembling, 
hyperexcitability,  cerebral  and  spinal  irritability,  indigestion,  constipation,  t}Tn- 
pany,  nosebleed,  bleeding  from  hemorrhoids,  profuse  sweats,  hysteric  manifestations, 
and  many  of  the  symptoms  that  accompany  the  beginning  of  the  function  (Currier). 
The  body  i)uts  on  fat,  which  often  liangs  in  ungainly  masses  on  the  back,  thighs, 
buttocks,  or  abdomen;  hair  often  appears  on  the  face,  and  the  habitus  in  general 
takes  on  a  masculine  type.  All  these  symptoms  are  the  result  of  the  atrophy  of 
the  genitalia.  The  ovaries,  tubes,  uterus,  vagina,  and  vulva  undergo  a  process  of 
senile  involution  and  atrophy.  For  further  information  on  the  changes  of  the 
menopause  the  reader  is  referred  to  Kisch  (loc.  cit.)  and  A.  F.  Currier. 

Vicarious  menstruation  is  a  periodic  discharge  of  blood  from  some  surface 
other  than  the  uterus,  wliich  discharge  is  to  represent  the  monthly  flow,  such  flow 
being  absent  from  the  uterus.  In  the  typical  cases  three  conditions  must  be  ful- 
filled— the  uterine  flow  must  be  absent;  the  periodicity  absolute,  and  the  organ 
from  which  the  vicarious  discharge  comes,  normal.  Such  cases  are  rare,  but  authen- 
tic ones  have  been  reported  (Kisch,  loc.  cit.).  Hemorrhages  have  been  observed 
coming  from  the  nose,  stomach,  lungs,  breasts  or  nipples,  mouth,  gums,  ear,  arms, 
bladder,  conjunctiva,  named  approximately  in  the  order  of  frecjuency.  Sometimes 
the  organ  from  which  the  hemorrhage  comes  is  diseased,  as  ulcer  of  the  stomach, 
tuberculosis  pulmonum,  ulcer  of  the  nasal  septum,  hemorrhoids,  chronic  otitis 
media,  and  in  themselves  would  give  rise  to  a  bleeding  surface,  but  when  the  peri- 
odicity of  the  flow  corresponds  to  that  of  the  menses,  the  latter  being  absent,  we 
still  speak  of  vicarious  menstruation.  Occasionally  the  usual  flow  is  combined  with 
a  blood}'  discharge  from  another  organ.  After  castration  vicarious  menstruation 
has  been  occasionally  observed,  and  during  pregnancy  and  the  amenorrhea  of 
lactation  a  vicarious  flow  may  occur  from  another  part  of  the  body.  The  author 
had  a  case  where,  for  nine  months  after  delivery,  the  patient  had  a  bloody  discharge 
from  the  nipples  lasting  several  days  and  recurring  every  twenty-eight  days.  The 
nipples  were  health}-  and  the  patient  amenorrheic.  These  hemorrhages  are  similar 
to  the  nosel)leeds  observed  during  pregnane}',  the  puerperium,  and  the  menopause. 

Occasionally  one  notices  not  a  bloody  flow,  but  an  increased  discharge  from 
some  organ,  such  as  leukorrhea,  diarrhea,  otorrhea,  salivation,  recurring  periodi- 
cally at  the  time  of  the  menses. 

Midperiod  Suppressed  Menses. — Between  the  periods  some  women  com- 
plain of  menstrual  molimina  without  the  discharge  of  blood.  The  pain  somethnes 
necessitates  rest  in  bed  or  even  an  anodyne.  Fasbender  described  the  s>'mptoms, 
and  Martin  named  it  "]\Iittelschmerz,"  or  pain  l)etween  the  periods.  There  may 
be  a  slight  increase  of  the  leukorrhea  at  this  time.  It  may  have  to  do  with  an 
atjT^ical  ovulation,  or  perhaps  it  is  the  evidence  of  mild  disease  of  the  ovary,  or 
a  specialh'  impressionable  nervous  system.

CONCEPTION 

Conception,  in  its  obstetric  sense,  means  the  union  of  the  male  and  female 
elements  of  procreation,  from  which  union  a  new  being  is  developed.  It  is  the 
means  for  the  propagation  of  the  species,  and  has  variously  been  termed  fecundation, 
impregnation,  fertilization,  incarnation. 

The  ovum  is  the  female  unit,  or  element,  of  procreation,  and,  as  has  been  learned, 
is  prepared  in  the  ovary  for  the  reception  of  the  male  unit,  which  is  the  spermato- 
zoid,  derived  from  the  testicle.  In  the  male  the  testicle  is  the  important  organ  of 
reproduction;  it  is  analogous  to  the  ovary,  and,  like  it,  has  many  organs  accessory 
to  it.  The  testicle  produces  an  internal  secretion,  the  interstitial  cells  of  Leydig 
probably  making  it. 

The  testicle  and  the  ovary  are  developed  in  the  fetus  from  identical  structures — 
the  germinal  folds  along  the  inside  of  the  Wolfhan  bodies.  The  germinal  epithelium 
in  the  one  case  develops  into  Graafian  follicles;  in  the  other  it  lines  the  tubuli 
contorti  of  the  testicle.  The  genesis  of  the  spermatozoids  is  very  similar  to  that 
of  the  ovum.  Whereas  the  spermatozoid  is  destined,  in  a  sort  of  division  of  labor, 
to  be  the  more  active,  aggressive  agent  in  the  function  of  impregnation  and  must 
seek  the  ovum,  by  a  process  of  evolution  it  is  given  a  shape  which  is  capable  of 
rapid  locomotion.  It  is  made  very  small,  being  the  smallest  of  cell  elements, 
having  been  divested  of  all  that  is  not  needed  for  the  performance  of  its  function, 
which  is  to  seek  out  the  female  pronucleus  and  fuse  with  it.  The  ovum,  on  the 
other  hand,  must  possess  the  nourishment  needed  for  the  new  life  until  the  egg  can 
derive  nourishment  from  its  parent.     It  is  the  largest  cell  in  the  body. 

The  spermatozoids  were  considered  animalcule  by  their  discoverers,  J.  Ham 
and  Leuwanhoek  (1677),  but  in  18-iO  Kollicker  and  Lallemand  proved  their  origin 
from  the  epithelial  cells.  Spallanzini,  in  1768,  proved  that  they  were  the  active 
fertilizing  elements  of  the  semen. 

The  spermatozoids  are  developed  in  the  tubuli  contorti,  not  in  the  rete  or  epididymis.  The 
periphery  of  the  tubule  is  covered  by  a  many-layered  epithelium,  similar  in  origin  to  the  germinal 
epithelium  of  the  ovary.  Like  the  latter,  it  can  be  differentiated  into  two  varieties  of  cells,  sper- 
miogones,  or  spermatoblasts,  analogous  to  the  primordial  ova,  and  supporting  cells,  or  Sertoli's 
cells,  analogous  to  the  cells  of  the  primordial  follicles  of  the  ovary.  Different  parts  of  the  tubuli 
are  active  or  quiet,  and  one  may  observe  all  tlie  various  stages  of  spermatozoid  formation  going  on 
in  the  same  testicle  (Hertwig). 

The  spermatogones  di\'ide  into  two  cells  called  spermocytes;  these  again  divide  and  again, 
reducing  at  the  same  time  the  number  of  cln-omosomes;  thus  out  of  two  spermatoblasts  eight 
spermids  develop.  Tlicse  obtain  notuishinciit  from  Sertoli's  cells.  The  nucleus  goes  off  to  one 
side,  and  its  chromatin  forms  the  head  of  th(>  finished  spermatozoid;  the  nucleolus  und  the  centro- 
some  form  the  neck;  the  protoplasm  of  the  cell,  the  tail.  Fig.  22  shows  human  spermatozoids 
under  higli  power.  They  are  .55  micra  long.  The  head  is  a  flattened  ovoid;  the  neck  is  short  and 
granulated;   the  tail  is  long,  ending  in  a  pointed,  unsheathed  prolongation. 

These  organisms  have  great  endurance  and  power  of  locomotion.  By  rapid  undulations  of 
the  tail  forward  progression  is  produced,  an<l  they  travel  ciuickly  all  over  the  genital  tract  of  the 
female.     The  life  tenacity  of  the  spermatozoids  is  remarkable:   one  may  freeze  them,  and  they  be-

least  three  weeks  in  the  Fallopian  tube;  in  the  bat  they  live  for  six  months,  and  in  the  hen  for 
at  least  eighteen  days. 

The  finished  spermatozoids  in  clumps  are  pushed  out  of  the  testicle  into  the  epididymis  l)y 
the  formation  of  sperm-cells  behind,  and  the  small  amount  of  fluid  secreted.  In  the  epi(lidJ^nis 
the  spermatozoids  break  out  of  the  clumps  and  attain  the  power  of  locomotion,  which  is  enhanced 
by  prostatic  .secretion.  Tiie  ciliated  epithelium  of  the  ductuli  efferentes  does  not  wave  and  can- 
not aid  in  the  propulsion  of  the  sp(>rma,  which  now  is  augmented  i)y  the  secretion  of  the  ductus 
epididj'midis.  The  motion  of  the  body  in  walking,  compre.-^sion  of  the  testicle  when  sitting,  the 
contraction  of  the  nuiscular  fibers  of  the  tunica  albuginea,  the  elas- 
ticity of  the  same  when  distended,  have  be<'n  advanced  as  cau.ses  of 
the  movement  of  sperma  out  of  the  testicle  and  epididjTnis.  The 
pa.ssage  of  the  semen  along  the  vas  deferen-s  Ls  accomplished  by  the 
contraction  and  expansion  of  the  vas,  perhaps  peristaltic,  aided  by 
the  ciliated  epithelium.  When  the  .semen  reaches  the  ampulla'  of 
the  vas  deferens,  it  accumulates  here,  awaiting  ejaculation,  ^\'ith

thra.    The  vesicuhe  seminales  are  not  receptacles  for  the  .semen,  but

chemic  influence  or  by  dilution.  The  spermatozoids  from  the  epidiilymis  of  the  dog  have  been 
found  capable  of  fertilization. 

The  semen  i.s  a  thin,  yoUowish-white,  creamy  fhiid,  alkaline,  mucilaginous, 
and  has  an  odor  peculiar  to  itself.  The  odor  is  due  to  a  mixture  of  the  various 
glandular  secretions,  particularly  that  from  the  prostate,  called  spermin.  The 
amount  discharged  varies  from  1  to  10  c.c;  the  average  is  3  c.c,  but  much  larger 
amounts  liave  been  collected.  It  contains  the  spermatozoids.  the  spermatic  cells, 
epithelium,  leukoc\'tes.  and  crystals.  The  number  of  spermatozoids  in  a  given 
ejaculation  is  sometimes  enormous— 227,500,000  in  one  discharge  (Lode).      With-

out  doubt  many  are  killed  by  the  acid  secretions  of  the  vagina.     The  number 
decreases  to  nil  if  cohabitation  is  carried  out  many  times  in  rapid  succession,  but 

regains   the  normal    after  a 
day's  rest. 

The  specific  gravity  of 
the  semen  varies  from  1027 
to  1046;  it  has  90  per  cent, 
water  and  6  per  cent,  mucin, 
the  rest  being  albuminoids, 
fats,  and  salts.  Spermin,  the 
odorous  element  of  the  semen, 
comes  mostly  from  the  pros- 
tate, but  it  has  been  found 
in  other  organs  and  fluids 
(Schreiner),  as  the  blood  of 
leukemia,  the  sputum  of  bron- 
chiectasis, the  testicle,  the 
ovary,  the  pancreas,  the 
spleen,  and  the  thvroid 
(Poehl). 

Copulation. — Concep- 
tion, impregnation,   incarna- 
tion, and    fecundation   must 
be    well    distinguished    from 
copulation,  which  means  the  sexual  union  of  the  male  and  the  female.

PUBERTY,  OVULATION,  AND  MENSTRUATION  23 

The  object  of  the  voluntary  act  of  copulation  is  solely  to  place  the  semen  in 
such  a  location  that  its  living  elements,  the  spermatozoicls,  may  reach  the  ovum. 
The  rest  of  the  function  of  reproduction  is  entirely  involuntary.  The  act  of  copu- 
lation is  not  absolutely  necessary;  if  the  semen  is  injected  into  the  vagina  or  even 
on  the  introitus  vulvae,  conception  may  take  place.  The  union  of  the  spermato- 
zoid  ^\^th  the  ovum  occurs,  in  all  probability,  in  the  outer  end  of  the  Fallopian  tube — 
its  pavilion.  The  freciuency  of  tubal  pregnancies  indicates  this.  That  the  impreg- 
nation may  occur  in  the  ovary  is  proved  by  authentic  ovarian  pregnancies, — indeed, 
several  primary  abdominal  pregnancies,  one  attached  to  the  omentum,  have  been 
reported, — and  that  the  union  of  the  two  elements  may  occur  in  the  uterus  itself 
is  not  impossible. 

How  does  the  ovum  reach  the  tube  from  the  ovary?  The  ovan»'  lies  in  a 
httle  depression, — the  fossa  ovarica  (Fig.  1), — and  is  covered  in  part  ])y  the  mesen- 
tery of  the  tube,  whose  fimbriae  are  in  close  proximit}-.  The  pavilion  of  the  tulje 
opens  outward  in  numerous  projections — the  fimbriae,  the  prolongations  of  the 
longitudinal  foldings  of  the  tube  (Figs.  23  and  24).  These  are  coverefl  with  ciliated 
epithelium.  The  waving  of  the  cilia  being  toward  the  uterus,  a  powerful  aspiratory 
current  is  produced  in  the  peritoneal  fluid  of  the  neighborhood  of  the  end  of  the 
tube.  Experimentally  in  rabbits  Lode  saw  tiny  particles  placed  near  the  tubes 
gradually  sucked  into  the  fimbriated  end.  They  appeared  finally  in  the  vagina. 
It  is  very  questionable  if  the  erection  of  the  tubes  on  the  ovary,  formerly  held,  could 
possibly  occur.  The  tube  is  too  delicate  to  lift  the  hea\y  intestines.  The  ovum 
as  it  appears  on  the  surface  of  the  ovary,  with  its  clump  of  cells  from  the  discus 
proligerus  and  a  few  drops  of  liquor  foUiculi,  is  caught  in  this  current  and  led  to  the 
tube.  Once  in  the  tube,  the  peristaltic  action  of  the  w'all  of  the  latter  ^ill  aid  its 
progression  toward  the  uterus,  aided  by  the  ciliary  wave.  The  length  of  time 
required  for  the  passage  from  ovary  to  uterus  in  the  dog  is  eight  to  ten  days;  the 
mouse,  four  to  five  days;  the  guinea-pig,  seven  days;  the  opossum,  five  days; 
in  the  human,  four  to  eight  days — but  of  this  one  cannot  be  certain.  The  figures 
are  for  the  fertilized  ovum.  The  only  unfertilized  human  ovmn  found  outside  the 
ovary  was  in  the  case  of  Hyrtl,  where,  four  days  after  the  beginning  of  the  jieriotl, 
the  woman,  a  virgin,  died,  and  at  the  microscopic  autopsy  an  uufjuestionable  ovum 
was  found  in  the  interstitial  portion  of  the  tube. 

How  do  the  spermatozoicls  reach  the  ovum  h-ing  in  the  pavilion  of  the  tube? 
There  are  several  theories  which  are  more  or  less  accepted: 

1.  That  the  semen  is  ejaculated  directly  into  the  uterus  is  disproved  by  the  anatomy  of  the 

parts.  .  1       -.I        I 

2.  That  the  penis  acts  as  a  piston,  forcing  the  semen  into  the  uterus,  is  not  plausible.     It 

occurs  onlv  in  pigs. 

3.  That  the  uterus  in  a  state  of  erection,  after  coitus,  relaxes  and  aspirates  up  the  semen, 
which  lies  in  a  pool  in  the  back  of  the  vagina,  into  which  the  cervix  dips.  There  is  some  color  to 
this  view,  but  if  so,  the  uterus  ought  to  suck  up  the  various  germs,  etc.,  existing  in  the  vagina, 
which  is  contradicted  by  the  fact  that  the  uterine  cavity  is  aseptic.  That  the  .<emen  is  held  back 
in  the  vagina  by  contraction  of  the  pelvic  floor  muscles  is  proved.  Owing  to  the  coagulation  of  the 
semen,  the  result  of  the  mixture  of  the  prostatic  with  the  .secretion  of  the  seminal  vesicles,  the  early 
discharge  from  the  vagina  is  hindered.  If  the  pelvic  floor  is  lacerated,  this  retentive  action  is  lost 
and  mav  give  the  cau.se  of  sterility.  •  j  i

6.  The  spermatozoids  get  into  the  uterus  by  their  own  natural  movements.  1  his  is  the 
most  generally  accepted  theory,  and  is  the  most  natural.  The  other  factors  may  help,  but  that 
the  wriggling 'motion  is  sufficient  to  bring  a  spermatozoid  to  the  tul)e  is  .^hown  by  the  numerous 
cases  of'^ fertilization  where  the  .-^emen  has  been  deposited  on  the  external  genitals,  as  in  ca.*es  of 
attempted  rape.  If  the  woman  is  strong  enough  to  resist,  there  is  no  immissio  penis,  and  the 
semen  may  he  discharged  on  the  vulva.  In  cases  of  pin-hole  h>Tnen  or  others,  where  immissio 
penis  is  impossible  or  was  not  permitted,  pregnancy  has  repeate^lly  taken  place,  the  semen  being 
deposited  on  the  vulva.  •     ■      n    r 

The  vaginal  mucus  is  acid  and  kills  the  spermatozoids,  but  that  of  tlie  cervix  is  alkalme, 
wherefore  the  uterus  would  have  a  chemotactic  attraction  for  the  spermatozoids— at  least  they 


24 


PHYSIOLOGY    OF    PREGNANCY 


would  find  conditions  much  more  favorable  to  their  movement.  The  cilia  of  the  tubes  and  uterus 
move  in  the  direction  of  the  internal  os,  and  this,  of  course,  would  hinder  the  upward  progress  of 
the  genoblasts,  but  they  overcome  this.  The  rate  of  travel  of  the  spermatozoids  has  been  variously 
estimated  from  1  to  -i'mm.  a  minute.  Assuming  the  average  rate  to  be  2  mm.,  the  70  mm.  long 
trip  through  the  uterine  cavity  would  require  thirty-five  minutes,  and  the  120  mm.  tube,  60 
minutes  more.  It  is  not  likely  that  the  movement  is  aided  by  antiperistalsis  of  the  tube;  rather 
one  would  imagine  the  lal)yrinthine  formation  of  the  tubal  passage  would  hinder  progress.  Sper- 
matozoids are  found  in  the  tube,  the  pelvic  peritoneum,  in  the  ovary,  witliin  a  few  hours  after 
cohabitation.  They  may  he  for  at  least  three  weeks  (Dlihrssen)  in  the  favorable  conditions  sup- 
pUed  by  the  infundibulum  of  the  Fallopian  tube.  Therefore,  if  there  is  no  ovum  ready  to  be 
fertilized  on  their  arrival  in  the  neighborhood  of  the  ovary,  they  wait  until  one  is  ripened  and 
expelled.  This  fact  is  very  important  in  medicolegal  cases,  where  the  question  of  legitimacy 
arises,  and  for  the  exact  computation  of  the  length  of  pregnancy. 

"When  the  spermatozoid  meets  the  ovum,  its  head  penetrates  the  zona  pellucida, 
which,  according  to  Fol,  of  Geneva,  is  soft.  It  loses  its  tail,  becomes  romid,  is 
surrounded  by  a  halo  of  radiating  lines,  and  progresses  toward  the  female  pronu- 
cleus. Fusion  takes  place.  The  rest  of  the  spermatozoids  die — at  least,  they 
disappear.     Kohlbriigge  says  that,  in  bats,  the  spermatozoids  enter  the  blastula 


CORPUS    LUT  EUM

and  affect  the  ovum,  and  that  they  also  enter  the  mucosa  uteri  and  luiite  Avith  the 
cells.  If  this  is  proved  for  the  human,  it  may  explain  several  phenomena  of  con- 
jugal life.  Millions  die  in  the  acid  vaginal  secretion;  others  are  lost  in  the  intricate 
passages,  but  since  only  one  is  necessary  for  fertilization,  nature  has  provided  in 
the  immense  number  for  all  contingencies. 

The  woman  is  now  pregnant,  the  fertilized  ovum  proceeds  to  the  uterus, 
propelled  by  the  cilia  of  the  tube  and  aided  by  its  peristalsis.  The  uterus  has  been 
prepared  for  the  reception  of  the  egg  (see  anatomic  changes  of  uterine  mucosa 
during  menstruation),  the  egg  attaches  itself  to  the  decidua  menstrualis,  and  the 
development  of  a  new  individual  is  begun.  These  processes  do  not  always  occur 
in  the  exact  order  described ;  observers  have  for  a  long  time  been  aware  that  vari- 
ations occur.  The  spermatozoids  may  pass  out  through  one  Fallopian  tube  and 
fertilize  an  ovum  lying  in  the  closed  uterine  horn  of  the  opposite  side.  This  is 
external  wandering  of  the  spermatozoid  (Fig.  25).  The  ovum  may  wander  from 
the  ovary  of  one  side  into  the  tube  of  the  other,  as  in  a  case  of  extirpation  of  the 
right  tube  and  left  ovary,  the  ovum  crossed  over  and'  entered  the  healthy  tube

a  great  deal  of  reservation,  because  the  permeability  of  the  stump  of  the  tube 
comes  into  question.     The  operations  to  procure  sterility  by  cutting  and  tying

the  tube  have  often  been  failures  becau.se  the  stump  l)ecomes  pervious.  The  only 
sure  method  of  permanently  interrupting  the  connection  between  ovary  and  uterus 
is  to  bury  the  cut  ends  of  the  tube  under  the  peritoneum,  or  to  exsect  the  uterine 
portion  of  the  tube.  Irf  the  above  discussion  accessory  tubes  or  accessory  astia 
of  the  tubes  must  be  corisidered. 


26  PHYSIOLOGY    OF   PREGNANCY 

It  is  easy  enough  to  explain  the  occurrence  of  external  wandering  of  the  ovum. 
The  ovaries  are  movable  organs,  and  by  certain  positions  of  the  parts,  e.  g.,  retrover- 
sion of  the  uterus  vnth.  prolapse  of  the  tubes  into  the  culdesac  of  Douglas,  are  brought 
close  together.  One  could  also  imagine  the  filling  of  the  rectum  and  sigmoid  as 
means  of  displacing  the  tubes.  Pathologic  adhesion  of  the  tubes  and  ovaries  may 
result  in  abnormal  currents  of  serum  created  by  the  cilia  of  the  tubes.  For  internal 
wandering  of  the  human  ovum  there  is  no  proof. 

The  Time  of  Conception. — It  is  important  to  know  the  time  pregnancy  begins, 
but,  unfortunately,  we  are  in  a  position  as  yet  only  to  guess  at  the  exact  date.  The 
knowledge  is  wanted  in  order  to  determine  the  day  of  confinement,  for  practical 
reasons,  for  the  scientific  study  of  the  development  of  the  ovum  in  the  uterus  and 
for  medicolegal  processes  in  the  question  of  legitimacy  of  a  child  or  its  paternity.. 
All  the  points  on  which  such  a  determination  could  rest  are  uncertain,  as:  (1)  The 
date  of  the  fruitful  coitus  (the  woman's  word  must  be  accepted) ;  (2)  the  date  the 
ovum  left  the  ovary,  and  whether  it  was  ripe  or  not ;  (3)  how  long  it  takes  the  ovum 
to  reach  the  tube  and  uterus — all  unknown  factors.  The  oldest  theory,  and  prob- 
ably the  correct  one,  is  that  ovulation  occurred  every  month,  coincident  with 
menstruation,  and  that  the  pregnancy  supervened  directly  after  the  flow  ceased, 
the  ovum  of  that  menstruation  having  been  fertilized.  Pregnancy  being  established, 
the  next  menses  did  not  appear.  As  far  back  as  we  have  authentic  records  the 
women  have  computed  their  time  of  pregnancy  from  their  last  menstruation. 
Experience  has  sho^vn  that  the  most  favorable  time  for  conception  is  just  after 
the  periods  have  ceased,  and  the  next  in  frecjuency,  just  before  the  periods  begin. 
Very  often  a  woman  will  have  one  period  even  after  pregnancy  has  been  established. 
The  newer  theory-,  held  by  Reichert  and  Lowenhardt,  that  it  is  the  ovum  of  the 
first  menses  missed  that  is  fertilized,  has  many  points  in  its  favor.  First,  of  16 
embryos  examined  by  Reichert,  12  showed  that  in  all  probability  they  had  been 
fertilized  about  the  time  the  menstruation  should  have  appeared.  Second,  very 
few  abortions  have  resulted  from  the  freciuent  use  of  the  uterine  sound.  Every 
gynecologist  believes  it  is  safe  to  sound  the  uterus  if  the  woman  has  not  missed  a 
period.  If  so  many  pregnancies  begin  with  the  last  menstruation,  it  should  have 
happened  that  the  young  ovum  has  been  frequently  injured.  On  the  other  side, 
it  must  be  said  that  prol)ably  many  such  abortions  never  w^ere  reported  or  even 
diagnosed;  they  may  have  been  delayed,  and,  further,  the  introduction  of  a  sound 
into  the  pregnant  uterus  does  not  always  cause  abortion.  Third,  the  Jews  are 
among  the  most  prolific  of  races.  The  law  required  their  women  (Leviticus  xv  :  19) 
to  leave  the  bed  of  the  husband  during  and  for  one  week  after  the  period,  at  which 
time  a  purifiying  bath  must  be  taken,  and  only  after  this  could  they  be  considered 
clean.  The  Jewish  women  date  their  pregnancy  from  the  first  night  after  this 
period  of  isolation.  This  might  prove  something  for  the  new  theory,  since  it  is 
not  probable  that  the  ovum  can  live  longer  than  eight  days.  In  the  lower  animals 
it  has  been  observed  that  if  the  ovum  remains  a  short  time  outside  of  the  ovary,  the 
zona  pellucida  becomes  impervious  to  the  spermatozoids. 

It  is  certain  that  conception  may  occur  at  any  time  during  the  reproductive 
life  of  women.  An  ovum  may  be  fertilized  by  spermatozoids  which  have  been 
waiting  for  many  days.  We  know  that  ovulation  occurs  between  the  periods. 
It  is  probable  that  most  conceptions  occur  just  after  and  just  before  the  time  of  the 
menses,  and  these  two  periods  must  be  considered  the  usual  ones.  No  doubt  the 
menses  may  occur  after  conception  has  taken  place.  It  is  customary  to  reckon 
the  length  of  pregnancy  as  of  nine  calendar  months,  or  ten  lunar  months,  two 
hundred  and  eighty  days'  duration,  dating  from  the  first  day  of  the  last  menstrua- 
tion. Clinical  experience  shows  that  most  lal^ors  occur  at  this  time.  If  the  newer 
theory  is  true  for  the  majority  of  cases,  one  will  have  to  conclude  that  the  normal 
length  of  pregnancy  is  two  hundred  and  fifty-two  days,  and  this  is  contradicted 


PUBERTY,    OVULATION,    AND    MENSTRUATION  27 

by  the  length  of  time  occurring  from  the  date  of  a  single  insemination  to  lal)or, 
i.  e.,  two  hundred  and  seventy-two  days,  which  is  the  average  of  a  large  number 
of  authentic  cases. 

Again,  if  the  theory  that  the  ovum  from  the  first  menses  missed  is  fertilized 
is  the  true  theory,  the  majority  of  women  ought  to  have  a  period  of  amenorrhea 
of  three  hundred  and  eight  days  instead  of  two  hundred  and  eighty  days,  during 
which  time  they  considered  themselves  pregnant.  But  we  know  that  in  the  great 
majority  of  the  cases  the  period  of  amenorrhea  is  of  only  two  hundred  and  eighty 
days'  duration.  Therefore  unless  we  are  \villing  to  admit  that  pregnancy  lasts 
only  two  hundred  and  fift\'-two  days,  we  must  concede  that  the  majority  of  con- 
ceptions occur  at  the  time  around  the  last  menses  present. 

The  season  of  the  year  influences  the  nmnber  of  conceptions.  The  months  of 
May  and  June  show  the  most,  perhaps  as  an  analogon  to  the  mating  of  birds  and 
animals.  In  many  countries  Alay,  June,  and  October  are  favorite  months  for 
marriages.  In  country  districts  during  the  harvest-time  there  are  fewer  concep- 
tions. The  body  is  tired  with  hard  work.  After  the  harvest  an  increase  is  notice- 
able. In  countries  where  conscriptions  for  soldiers  take  place,  there  are  many 
conceptions  before  the  time  the  men  leave  for  the  army.  Illegitimate  conceptions 
occur  most  often  during  the  summer  months.  Climate  exerts  an  influence,  too; 
in  the  very  cold  regions  the  frequency  of  conception  is  less;  in  Avarm  zones  the 
contrary  is  true.  Among  the  educated  classes  conception  is  voluntarily  much 
interfered  with,  ])ut  there  are  those  who  believe  that  the  number  of  impregnations 
falls  off  among  them  from  natural  causes.

CHAPTER  II 

DEVELOPMENT  OF  THE  OVUM 

The  union  of  the  spermatozoid  and  the  ripened  ovum  has  never  been  observed 
on  the  higher  animals,  but  Sobotta  has  described  the  phenomenon  as  it  occurs  in 
the  mouse,  and  Wilson  and  Matthews  and  Hertwig,  in  the  sea-urchin.  It  was 
first  observed  by  Barry  in  1838.     The  process  in  all  is  about  the  same,  and  probably

in  the  human  varies  little  from  what  we  observe  in  animals.  The  spermatozoid — 
and  only  one — burrows  with  its  head  into  the  zona  pellucida,  which  rises  in  a  little 
hill — the  ^'■com  cVattraction"  of  Fol — to  meet  it.  This  is  probably  the  result  of 
chemic  action  (Fig.  28).     After  the  head  has  passed  into  the  ovum,  the  tail  dis-

appears  and  the  cell-nKniibrane  thickens,  which  prevents  other  sperinatozoids 
from  entering  the  egg.  The  neck  of  the  si)erniatozoid  becomes  the  centrosome 
(not  present  in  all  species) ;  the  head  swells  up  and  becomes  the  male  pronucleus. 
Both  nuclei  are  made  up  almost  wholly  of  chromatin  fnuclein).  The  i)rotoi)la.sm 
is  arrang(Hl  in  radiating  lines.  The  nuclei  gradually  a])proach  each  other  and  fuse, 
the  chromatin  of  the  two  forming  one  long  convoluted  thread.  The  nucleus  is 
now  capable  of  equal  division;  it  is  the  primary  "segmentation,"  or  "embryonal 
nucleus."  The  centrosome  forms  the  starting-point  of  the  first  karyokinetic 
figure  (Fig.  32). 

When  the  first  division  of  the  embryonic  nucleus  has  been  completed,  each

daughter  nucleus  receives  an  equal  number  of  chromosomes;  then^tore  each  cell 
is  endowed  with  half  paternal  and  half  maternal  qualities  and  attributes.  The 
heredity  of  race,  of  external  form,  of  family  traits,  of  susce])til)ility  to  disease,  and 
in  rare' instances  of  disease  itself,— insanity,— is  transmitted  to  the  new  indiviilual 
through  the  chromatin  of  the  male  and  female  pronuclei.  This  must  have  chemic 
and  structural  qualities  which  are  far  beyond  our  physical  powers  of  discovery, 
since  within  the  microscopic  mass  of  chromatin  are  contained  the  elements  that 
develop  into  millions  of  cells,  of  the  most  diverse  ilescription,  and  carrying  on 
most  varied  functions. 

The  segmentation  nucleus  forms  a  spindle  with  a  centrosome  at  each  end;   the 


30 


PHYSIOLOGY   OF   PREGNANCY 


chromatin  is  arranged  around  the  middle  at  first,  then  it  divides  in  two  equal  parts, 
going  toward  the  ends.  The  achromatic  fibers  of  the  spindle  dissolve  in  the  middle, 
forming  thus  two  nuclei,  and,  while  this  process  goes  on  inside,  the  cell  protoplasm 
outside  divides  also.  The  process  of  karyokinesis  is  now  complete.  Two  cells  are 
formed,  and  thus  the  new  individual  is  begun.  Each  daughter-cell  divides  again 
into  two  and  again  in  geometric  progression  until  a  mass  of  cells  results  (Fig.  36). 
This  mass,  which  resembles  a  blackberry  in  shape,  is  called  the  morula.  All  its 
cells  have  the  same  qualities  as  the  parent  cell,  because  broken  pieces  of  the  morula 
have  l^een  found  to  grow  into  a  complete  embryo  (Driesch) .  These  changes  occur 
inside  the  zona  pellucida,  while  the  ovum  is  passing  down  the  tube.  The  cells  of 
the  corona  radiata  are  lost  during  the  transit  through  the  tube.  When  the  morula 
has  passed  the  uterine  end  of  the  tube,  at  which  time  it  cannot  be  much  more  than 
0.2  mm.  in  diameter,  it  attaches  itself  to  the  wall  of  the  uterus. 

The  next  step  in  the  development  of  the  egg  is  the  blastula  formation.  The 
cells  of  the  morula  multiply  ^^dth  great  rapidity,  and  a  seruni  appears  in  their 
center  which  forces  the  cells  to  arrange  themselves  around  the  periphery  of  the  egg, 
forming  the  blastodermic  vesicle.  The  zona  pellucida  is  stretched,  persisting  a 
varying  length  of  time  after  the  impregnation  of  the  egg. 

The  blastodermic  vesicle  (Fig.  37)  at  first  consists  of  a  single  layer  of  cells,

with,  at  one  pole,  an  accumulation  of  darker  pigmented  cells — the  later  area 
embryonalis.  This  layer  divides  into  two — an  outer,  called  epiblast,  ectoderm,  or 
ectoblast,  and  an  inner,  the  endoblast  or  entoderm,  separated  by  a  space.  The 
egg  is  now  called  a  gastrula  (Fig.  38),  and  a  third  layer  of  cells  develops  between 
the  other  two,  called  the  mesoblast,  or  mesoderm.  This  later  divides  into  two — 
the  splanchopleure  and  the  somatopleure ;  thus  are  we  introduced  to  the  study  of 
embryology,  which  does  not  belong  in  the  pages  of  this  book.  Only  such  points 
as  are  necessary  for  the  consideration  of  the  formation  of  the  fetal  envelops  will 
be  presented. 

The  uterine  mucosa  has  already  been  described.  Under  the  influence  of  the 
corpus  luteum  it  has  been  prepared  for  the  reception  of  the  fertilized  egg.  It  is 
thicker,  velvety,  soft,  spongy,  vascularized,  and  the  glands  are  full  of  clear  secre- 
tion. The  condition  of  the  ovum  as  it  enters  the  uterine  cavity  is  unknown; 
probably  it  is  in  the  blastula  or  gastrula  formation.  Probably  the  zona  pellucida 
has  disappeared,  and  with  it  the  cells  of  the  membrana  granulosa,  the  corona 
radiata. 

One  of  the  earliest  human  eggs  ever  described  is  that  of  Kretz-Peters,  and 
since  the  findings  in  this  egg  are  supported,  in  the  main,  by  those  of  other  human 
ova  (v.  Spee)  and  of  animals  (Hubrecht  and  others),  the  conclusions  drawn  by 
Peters  will  be  generally  accepted  in  the  following  description.     (See  also  Bryce,

uterus,  or,  and  more  probably,  its  epiblastic  cells  eat  their  way  through  the  epithelium, 
and  the  ovum  thus  arrives  in  the  edematous  subepithelial  connective-tissue  stroma. 
The  ovum  does  not  enter  the  mouth  of  a  uterine  gland;  it  does  not  necessarily 
fall  into  one  of  the  uterine  folds,  though  it  is  possible,  but  then  the  changes  that

would  follow  would  not  vary  from  the  usual;  it,  by  a  process  of  arrosion,  burrows 
into  the  endometrium.  This  reacts  to  the  invasion  by  a  local  congestion,  with 
edema,  diapedesis  of  white  and  red  blood-corpuscles,  and  a  thickening  of  the  outer 
layers  of  the  stroma  cells  of  the  nmcous  membrane.     The  spindle-shaped  cells 


32 


PHYSIOLOGY    OF    PREGNANCY 


under  the  epithelium  and  around  the  glands  quickly  form  large  rounded  or  ovoid 
cells  with  a  single  nucleus,  the  decidual  cells.  These  are  much  more  numerous 
near  the  surface,  forming  a  rather  compact  layer.  The  glands  widen  and  undergo 
proliferation  at  the  base,  and  are  filled  with  secretion.  In  olden  times  this  was 
called  the  uterine  milk.  The  decidua  menstruationis  is  being  transformed  into  a 
decidua  graviditatis,  and  the  two  layers,  compacta  and  spongiosa,  are  already 
being  differentiated.  (See  pp.  13  and  14,  under  Menstruation.)  In  the  early 
stages  the  two  may  hardly,  if  at  all,  be  differentiated. 

The  ovum  sinks  into  the  compacta;  the  opening  through  which  it  entered  is 
closed  by  a  mushroom-like  cap,  or  by  the  growth  of  the  lateral  portions  of  the 
decidua  and  epithelium  over  the  tiny  aperture.  The  changes  in  the  human  ovum 
up  to  this  time — about  the  eighth  daj^,  not  as  Peters  would  have  it,  the  third  or 
fourth  day — are  unknown.     In  the  Kretz-Peters  egg,  the  first  fetal  formation  was

already  in  progress,  the  amniotic  cavity  and  chorion  being  completed.  The  epi- 
blast  or  ectoderm — rather,  that  layer  not  concerned  in  the  formation  of  the  embryo — 
grows  into  the  decidua,  and  provides  for  the  nourishment  of  the  egg.  It  is  the 
epithelium  of  the  chorion,  and  is  called  trophoblast,  because  of  its  nutritive  function. 
The  cells  are  irregularly  cubic,  with  a  large  round  or  oval,  slightly  granular  nucleus, 
and  sometimes  with  a  nucleolus.  Possibly  they  secrete  an  enzyme  which  destroys 
the  superficial  cells.  The  trophoblast  grows  into  the  compacta  in  all  directions, 
but  irregularly,  and  when  it  meets  the  dilated  capillaries,  it  pushes  into  them,  the 
(nidotlielium  of  the  latter  l)eing  destroyed,  thus  allowing  the  blood  to  wash  the 
surface  of  the  trophoblast.  This  causes  the  cell  protoplasm  to  swell  up,  the  cells 
to  form  a  homogeneous  mass,  and  the  nuclei  to  alter  and  assume  irregular  forms — 
the  syncytium.  The  trophoblast  forms  a  shell  around  the  egg,  which  lies  free  in 
the  dilated  capillaries  of  the  thickened  mucosa.     The  area  around  the  trophoblast

and  the  growth  of  the  ovum.     In    ?5;  I 

early  fetation  the  uterine  glands     ^  | 

are  filled  with  blood,  and  this  oc- 
curs so  regularly  in  all  the  latest 
specimens  that  it  may  be  consid- 
ered normal.  The  blood  also  flows 
in  tunnels  and  lacunae  formed  in 
the  trophoblast.  We  thus  see  the 
first  act  of  the  formation  of  the 
intervillous  spaces. 

From  the  mesoblastic  laj'er 
of  the  ovum  connective  tissue 
brought  by  the  allantois  and 
carrying  fetal  blood-vessels 
presses  into  the  irregular  in- 
growths of  the  trophoblast  (see 
Plate  I),  and  thus  the  first  villi 
are  formed. 

The  growth  of  the  ovum  is 
favored  by  the  thickening  or 
hyperplasia  of  the  mucous  mem- 
brane, which  is  soon  bulged  out- 
ward toward  the  cavum  uteri  in 
the  form  of  a  hemisphere.  The 
glands  are  separated  from  each 
other  (Fig.  40),  and  arrange  them- 
selves tangentially  to  the  grow- 
ing ovum.  The  layer  of  mucous 
membrane  that  is  pushed  up  in 
the  form  of  a  cover  is  called  the 
decidua  capsularis;  that  portion 
on  which  the  ovum  rests,  the 
decidua  basalis,  and  all  the  rest 
of  the  lining  of  the  uterus,  the 
decidua  vera.  The  term  mem- 
brana  decidua  was  applied  to  u 
supposed  fibrinous  exudation  on 
the  lining  of  the  uterus  during 
pregnancy,  and  named  "decidua," 
or  "caduca,"  because  it  is  cast  off 
during  labor  and  the  puerperium. 

Matthew  Baillie  taught  that  preg- 
nancy caused  an  exudate  to  appear  on 
the  surface  of  the  endonu'triuni,  aii<l 
that  the  ovum  coming  down  the  tul)e 
pushed  this  membrane  ahead  of  it. 
wherefore  this  latter  portion  was  called 
decidua  reflexa.  Since  the  same  kind 
of  membrane  was  found  imder  the 
ovum,  it  was  thought  that  this  was 
formed   later,  therefore,  decidua   sero-  ,     ,      ,.rr  j      rr  •        r.u 

tma.     Wm.  Hunter  (1774)  retained  these  names,  but  described  a  ditterent  mode  of  formation  of  the 
reflexa,  according  to  which  the  ovum  is  surrounded  by  a  reduplication  of  the  decidua  vera,  is  walled

around,  and  covered  over  by  the  growth  of  the  exuberant  decidua.  Another  notion  was  that  the 
ovum  was  caught  between  two  folds  of  the  thickened  decidua  menstrualis.  This  may  be  true  in 
some  cases.  Many  authors  still  retain  the  old  names  reflexa  and  serotina,  but,  according  to 
modern  ideas  of  the  histology  of  the  endometrium,  the  terms  capsularis  and  basaUs,  proposed  by 
His,  are  better. 

The  endometrium  undergoes  many  changes  from  the  lieginning  to  the  end  of 

pregnancy.       The    cervical    mucous

membrane  normally  takes  no  part  in 
the  formation  of  the  decidua.  It 
undergoes  marked  changes  which 
Avill  be  considered  later.  Sometimes 
the  ovum  becomes  attached  in  part 
to  the  cervix,  but  this  is  pathologic 
(placenta  prsevia).  In  the  first  weeks 
the  lining  of  the  uterus  is  hardly  dis- 
tinguishable from  the  membrane  of 
menstruation.  The  marked  prolifer- 
ation of  the  glands,  resulting  even  in 
a  papillary  formation  with  clumped 
epithelium,  which  Opitz  declared 
characteristic  for  pregnancy,  the  vas- 
cularity, the  beginning  formation  of 
decidual  cells,  the  thickening,  all  these 
are  similar,  so  that  no  one  can  positively  identify  a  given  l)it  of  tissue  as  having  come 
from  one  or  the  other  condition.  At  the  end  of  the  third  month  the  decidua  vera  has 
reached  its  greatest  development.  The  membrane  on  the  anterior  and  posterior  walls 
is  thickest,  even  as  much  as  1  cm.,  the  areas  at  the  sides  of  the  uterus,  and  usually  the 
fundus,  are  less  thickened,  and  when  the  lining  is  cast  off,  as  in  al^ortion  at  this  time, 
the  edges  present  a  sieve-like  appearance  from  the  openings  of  the  uterine  glands

pass  to,  and  sometimes  slightly  into,  the  muscularis.  The  glands  pursue  a  straighter 
course  in  the  basilar  portions  of  the  compacta  than  in  the  spongiosa.  The  arteries 
rise  in  spirals  around  the  glands,  up  to  the  surface,  where  they  break  into  capillaries. 
Around  the  insertion  of  the  ovum  the  blood-vessels  are  most  numerous  and  the 
capillaries  most  dilated.  The  veins  here  are  enlarged,  and  open  into  the  inter- 
villous spaces.     The  glands  are  pushed  aside  by  the  growing  ovum  (Fig.  40).

The  decidua  basalis  or  serotina  is  a  portion  of  the  decidua  vera  altered  only  by 
the  superimposed  growing  ovum.  It  has  the  compacta  and  spongiosa,  but  the 
glands  and  blood-vessels,  which  latter  are  enormously  developed,  are  stretched  to 
a  plane  parallel  to  the  wall  of  the  uterus,  and,  at  the  junction  of  the  reflexa,  curve 
in  arches  upward  into  it.  (See  Fig.  40.)  The  jiortion  of  the  basalis  next  to  the 
chorion  or  tro]:)hoblast  is  called  the  trophosphere,  and  will  be  again  consitlered 
under  the  head  of  Placentation.  The  basalis,  of  course,  nmst  grow  rapidly  in  the 
flat  to  keep  up  \\'ith  the  growing  o\'aim,  and  this  it  does  both  l)y  its  outi  hyperplasia 
and  by  the  splitting  of  the  compacta  of  the  neighboring  vera.  The  glands  of  the 
basalis  (or  serotina)  degenerate  early,  and,  owing  to  the  great  and  rajiid  growth 
of  the  area  of  insertion  of  the  ovum  (the  site  of  the  future  placenta),  are  compressed 
into  a  low,  lamellous  layer  of  spong}'  tissue.  The  basalis  shows  productive  as  well 
as  degenerative  changes,  and  they  ^\"ill  also  be  considered  under  Placentation. 

The  decidua  reflexa,  or  capsularis,  is  that  portion  of  the  vera  which  is  stretched 


36  PHYSIOLOGY   OF    PREGNANCY 

over  the  ovum.  It  is  thick  at  the  equatorial  portion  and  thin  at  the  outer  pole. 
This  is  the  point  where  the  egg  buried  itself  in  the  mucosa.  This  point,  which  is 
microscopic,  is  soon  covered  in,  so  that  in  later  stages  it  cannot  be  found.  The 
portions  near  the  base  resemble  the  vera;  the  blood-vessels  are  more  numerous; 
the  veins  larger,  and  the  capillaries  open  into  intervillous  spaces.  The  glands  are 
arranged  tangentially  around  the  ovum,  and  one  finds  glands  opening  obliquely 
on  the  surface  (not  into  the  cavity  of  the  trophosphere) ,  almost  up  to  the  vertex  of 
the  refiexa.  The  tissue  is  soft;  the  decidual  cells  numerous;  also  the  so-called 
syncytial  giant-cells.  The  uterine  epithelium  is  flattened  at  the  vertex,  cuboid  at 
the  sides,  without  cilia,  and  disappears  early.  The  portions  of  the  decidua  near 
the  top  of  the  capsularis  early  assume  a  fibrinous  character,  without  glands,  vessels, 
or  epithelium,  all  these  disappearing  as  the  apex  is  reached. 

As  the  ovum  grows  and  fills  out  the  cavity  of  the  uterus  the  deciduse  undergo 
mam^  and  material  changes.  The  refiexa  is  stretched  over  the  ovum,  and  soon  reaches 
the  opposing  wall  of  the  uterus,  on  which  it  lies,  but  does  not  adhere.     The  uterine 


Fig.  46. — Decidu.^  Vera  at  Term  (low  power). 

cavity  is  completely  obliterated  by  the  fourth  month.  The  refiexa  undergoes 
coagulation  necrosis,  and  is  absorbed  at  the  sixth  month,  though  occasionally 
portions  of  it  can  be  found  on  the  membranes  at  term.  At  the  edges  of  the  placenta 
one  usually  finds  a  thick  layer  of  decidua  in  fibrinous  degeneration,  the  site  of  the 
transition  of  vera  and  basalis  into  refiexa.  This  is  the  closing  ring  of  Nitabuch- 
Winkler. 

The  decidua  vera  grows  rapidly  in  thickness  vmtil  the  end  of  the  third  month; 
from  then  on  it  thins  out  until  at  term  (Fig.  47)  it  is  only  1  mm.  thick  or  in  places 
even  less.  It  must  grow  actively,  also,  because  it  has  not  enough  tissue  to  stretch 
and  cover  the  immense  ovum  at  term.  The  epithelium  is  all  gone  except  in  the 
glands  of  the  lowest  layers  of  the  spongiosa  and  those  between  the  muscle-bundles. 
From  these  remnants  the  new  uterine  mucosa  is  reconstructed.  The  compacta  is 
reduced  to  a  narrow  strip,  and  most  of  the  decidual  and  stroma  cells  are  in  a  process 
of  coagulation  necrosis.  The  glands  of  the  compacta  are  separated  from  each  other, 
while  in  the  spongiosa  they  form  a  thin,  loose,  flattened  network,  and  since  the 


DEVELOPMENT    OF   THE    OVUM  37 

stroma  here  too  is  Ijoginnins  to  degenerate,  separation  of  the  ovum  from  the  uterine 
wall  is  easy.  Nature  is  thus  preparing  the  way  for  the  release  of  the  produet  of 
conception.  The  basalis  undergoes  the  most  marked  transformation,  Ijecause  here 
the  egg  is  inserted  and  the  placenta  is  situated.  Its  structure,  therefore,  is  inti- 
mately associated  with  the  placenta,  and  the  description  of  the  two  will  be  combined. 


PLACENTATION 
We  have  learned  how  the  ovum  attaches  itself  to  the  uterine  mucosa  by 
burrowing  through  the  epithelium  into  the  stroma.  At  this  time  it  probably  ha.s 
passed  the  morula  stage  into  the  blastula  stage,  and  although  it  cannot  be  ])r(jved, 
probably  there  exists  at  this  time  an  outer  epiblastic  layer  with  syncytial  character- 
istics, i.  e.,  a  trophoblast.     At  this  time,  also,  and  certainly  within  a  few  days,  there

exist  the  three  layers  of  the  ovum — tlic  ectoderm,  the  entoderm,  and  the  mesoderm. 
The  amniotic  cavity  also  is  formed,  because  one  of  the  youngest  human  eggs,  Peters', 
whose  age  is  estimated  at  not  over  eight  days,  shows  this.  The  ectoderm  is  split 
by  the  amnion  (Fig.  61),  the  outer  layer  forming  the  trophoblast,  the  inner  layer 
sinking  toward  the  center  of  the  ovum,  and,  with  the  central  mesoderm  and  ento- 
derm, forming  the  embryo.  While  the  troi)hol)last  grows  into  the  decidua  in  all 
directions,  the  mesoblast  grows  out  underneath  it,  and  blood-vessels  with  connective 
tissue  spread  out  in  the  latter,  coming  from  the  abdominal  ]H>dicle  of  the  embryo. 
Thus  we  have  a  condition  represented  in  Fig.  63. 

The  trophoblast  sends  finger-like  jirocesses,  called  villi,  into  the  decidua,  the 
cells  of  which  are  dissolved  and  absorbed,  perhaps  used  in  the  nourishment  of  the 
ovum.  These  villi  are  at  first  solid  masses  of  cells,  and  they  break  into  the  dilated 
and  new-formed  capillaries,  pushing  the  endothelium  before  them,  and  destroying 
it.  The  maternal  blood  now  bathes  the  outside  of  the  trophoblast.  and  by  its 
action  changes  the  superficial  layers  of  epithelium  into  syncytium  (Peters),  and 


38  PHYSIOLOGY    OF    PREGNANCY 

forms  irregular  blood-spaces  or  lacuna?  in  it.  The  lacuna?,  therefore,  are  both 
intravascular  and  extravascular,  /.  e.,  are  both  dilated  capillaries  and  new  spaces 
formed  in  the  trophoblast,  and  they  are  the  beginnings  of  the  intervillous  caverns 
soon  to  be  described. 

The  solid  trophoblastic  processes  or  \'illi  are  invaded  from  the  embryonal  side 
by  mesoblast  carrying  the  blood-vessels,  and  thus  typical  villi  with  an  inner  core 


Syncytium

of  mesoblastic  tissue,  and  a  covering  of  trophoblast,  in  which  two  layers  can  early 
be  distmguished,  are  formed.  The  outer  layer  is  a  strip  of  protoplasm  without 
cell-walls  and  wth  numerous  large  oval  nuclei,  the  svncytium.  In  places  this 
syricytmm  is  massed.  Underneath  is  a  layer  of  low  cuboid  mononucleated  cells, 
which  take  the  stain  better— the  Langhans'  layer.  Langhans,  in  1882,  proved 
that  there  were  two  layers,  and  the  lower  one  is  named  after  him.  Preparations 
fixed  m  Flemmmg's  mixture  show  the  syncytium  to  be  covered  with  cilia.     The 


DEVELOPMENT    OF   THE    OVUM 


39 


funf'tion  of  these  cilia  is  unknown.  In  the  viUi  at  term  tlie  cilia  are  low,  almost 
indistinguishaljle,  and  the  layer  of  Langhaiis  also  lias  nearly  all  disappeared.  The 
stroma  of  the  early  villus  is  made  up  of  a  reticulated  substance,  fibromucoid,  spin- 
dle, or  star-shaped  cells,  separated  by  spaces  resembling  lymph-spaces.  There  are 
also  large  vacuolated  cells,  often  containing  fat-gloljules  distriljuted  through  the 
stroma  (Figs.  48  and  49).  These  cells  probably  are  much  concerned  in  the  bio- 
chemic  changes  occurring  in  the  placenta.  In  the  later  and  more  developed  villi, 
and  in  the  trunks  of  the  villi,  fibrous  tissue  preponderates  in  the  stroma.  In  the 
stroma  lies  a  mesh  of  capillaries,  fed  by  an  arteriole  and  emptied  by  a  venule. 
These  Ijlood-vessels  are  found  as  earh'  as  the  second  week,  and  are  brought  with 
connective  tissue  from  the  abdominal  pedicle  of  the  eml)ryo  connnunicating  with 
the  aorta.     Thus  it  is  seen  that,  from  the  start,  the  circulations  of  the  mother  and

the  fetus  are  distinct  and  do  not  intermingle.  The  blood  of  the  child  circulates 
inside  the  villus;  the  blood  of  the  mother  circulates  outside,  around  the  villus. 
As  the  ovum  grows  the  villi  increase  in  number  and  comjilexity.  They  branch 
again  and  again,  forming  long  tufts,  and  soon  the  whole  surface  of  the  chorion  is 
covered  by  a  thick  fur  of  villi  (Pig.  50).  Those  villi  that  grow  toward  the  refiexa, 
or  capsularis,  find  scant  nourishment,  and,  too,  a  decidua  that  is  being  stretched 
and  undergoing  necrosis,  wherefore  they  also  soon  atrophy  and  disappear.  The 
process  is  started  in  the  fourth  week  and  is  finished  by  the  ninth,  but  .sometimes 
villi  persist  in  the  capsularis,  forming  a  refiexa  placenta.  The  basalis  is  very  richly 
supplied  Avith  blood;  indeed,  its  structure  is  almost  cavernous,  and  the  villi  here 
take  on  luxuriant  growth  (Figs.  51  and  52).  This  is  the  future  placenta  or  chorion 
frondosum.  The  atrophied  chorion  is  called  the  chorion  hrve.  In  the  first  weeks 
of  life  the  ovum  is  firmlv  embedded  in  the  uterine  wall;    then,  owing  to  the  rapid

PHYSIOLOGY    OF   PREGNANCY 


gro^\i:h  of  the  villi  and  their  loose  attachment  (but  still,  attachment)  to  the  dilated, 
newly  formed  blood-vessels,  it  is  possible  easily  to  lift  the  ovmn  out  of  its  bed. 
Early  abortions  then  give  us  specimens  as  in  Figs.  50  and  51.  There  are  in  such 
cases  many  villi  and  pieces  of  villi  still  remaining  adherent  to  the  basalis,  or  serotina. 
These  are  called  anchoring  villi,  because  the  sj'n- 
c>i;ium  on  them  has  bm-rowed  deeper  into  the 
decidua,  and  sometimes  even  has  pierced  into  a 
dilated  vein  at  the  site  of  the  placenta  (Fig.  53). 
The  villi  continue  to  multiply,  growing  into  the 
decidual  base,  which  also  grows  outward  among 
the  tufts  of  the  villi.  These  outgr  :>wths  of  de- 
cidua carry  the  arteries  and  veins  of  the  uterus, 
and  in  the  ripe  placenta  are  represented  only  by 
thin  partitions  between  the  large  lobes  or  coty- 
ledons of  the  placenta.     The  arteries  pursue  a

spiral  course  through  the  uterine  muscle,  the  basalis,  and  the  septa,  while  the  veins 
are  straight.     As  these  vessels  approach  the  placental  site  they  lose  all  their  coats

save  one  layer  of  endothelial  cells,  forming  large  sinuses,  really  not  distinct  vessels, 
between  the  muscular  lamellae  and  in  the  decidua. 

We  have  seen  how  the  villi  come  to  dip  into  the  maternal  blood,  which  flows  in 
lacunae  formed  by  the  dilated  capillaries  and  spaces  in  the  periphery  of  the  tropho-

pression  and  absorption  by  the  trophoblast,  the  compacta  is  nearly  all  destroyed, 
the  villi  lying  against  the  spongiosa  and  a  few  (anchoring  villi)  dipping  into  it.

DEVELOPMENT    OF   THE    OVUM  43 

The  villi  grow  in  the  diroction  of  the  venous  oix'nings  and  away  from  the  arteries, 
the  blood-stream  naturally  swinnning  them  in  this  direetion.  They  stretch  the 
venous  sinuses,  and  by  pressure  necrosis  destroy  the  decidua  compacta  between  the 
veins,  until  only  the  septa  carrying  the  arteries  are  left  (Fig.  o5).  The  capillaries 
and  veins  of  the  compacta  are  developed,  as  the  placenta  grows  large  and  hea\'y, 
into  extensive  caverns  filled  with  the  inextricably  mingled  branclied  trees  of  villi 
floating  in  maternal  blood  (Fig.  54).  These  caverns  are  fed  Ijy  the  arteries  which 
ascend  the  septa  placentae,  and  are  emi:)tied  by  the  veins  of  the  placental  site. 
These  vessels  may  be  easily  seen  on  the  full-term  placenta  (Fig.  56). 

The  maternal  blood  in  the  intervillous  spaces  is  in  constant  circulation.  The 
arteries  in  the  septa  bring  it,  the  veins  on  the  surface  of  the  cotyledons  empty  it, 
into  the  uterine  sinuses.  The  circular  sinus  also  collects  the  Ijlood  from  all  the 
cotyledons,  serving  as  an  anastomosis.  The  movement  of  the  blood  is  aided  by 
uterine  contractions  which  occur  at  intervals  thi'oughout  pregnancy. 

The  placenta  grows  in  the  flat  and  in  tliickness,  and  about  the  fourth  month 
takes  up  one-half  of  the  area  of  the  uterus;    at  the  end  of  i)regnancy  the  i)lac-enta

occupies  one-fourth  to  one-third  of  the  uterine  expanse.  Its  weight  increases  at 
the  rate  of  60  gm.  a  month  until  the  seventh  month,  then  50  gm.,  antl,  in  the  tenth 
month,  less  than  10  gm.  The  growth  of  the  villi  in  the  flat  is  permitted  by  a  split- 
ting of  the  decidua  vera  at  the  periphery  of  the  placenta,  and  at  the  same  time  by 
an  increase  of  the  area  of  the  placental  base  caused  by  the  growth  of  the  uterus. 
When  the  reflexa  unites  definitely  with  the  vera,  there  remains  a  thickened  ring  of 
decidua  at  the  junction  of  the  serotina  and  reflexa,  and  the  villi  of  the  reflexa  atrophy- 
ing, whik;  those  of  the  serotina  grow,  the  latter  spread  out  under  the  attached  ring 
of  decidua  for  a  short  distance.  This  is  exaggerated  when  there  is  a  pathologically 
early  adherence  of  the  deciduse,  or  if  the  natural  splitting  of  the  vera  is  interfered 
\^^th.  A  placenta  marginata  and,  in  marked  instances,  placenta  circumvallata, 
are  thus  produced.  The  ring  of  decidua  is  called  the  decidua  sulx'horialis.  By 
some  it  is  referred  to  as  the  Waldeyer  closing  ring;  by  others,  the  edge  of  the  closing 
plate  of  Winkler.  The  ]ilacenta  is  seen  to  be  composed  of  two  parts— one,  very 
minute  in  quantity,  derived  from  maternal  tissues;  the  other  from  fetal,  both 
inextricably  intergrowTi.

The  two  umbilical  arteries  from  the  child  spread  out  on  the  fetal  surface  of  the 
placenta,  divide  and  redivide,  until  each  cotyledon  is  provided  with  a  branch. 


Decidua  reflexa

These  branches,  which  have  vasa  nutrientia,  split  up  into  numerous  twigs,  and  from 
each  twig  a  bunch  of  villi  hangs.     Each  villus  is  provided  with  an  arteriole  which 

breaks  into  a  convolution  of  intercommunicating 
capillaries.  The  blood  is  gathered  by  a  venule  to 
which  the  venules  of  the  other  villi  are  joined,  until 
large  venous  trunks  are  formed  which  unite  on  the 
fetal  surface  of  the  placenta  to  form  one  large  vein, 
— the  umbilical  vein, — which  passes  in  the  navel- 
string,  the  umbilical  cord,  to  the  child.  The  cir- 
culation in  the  villi  is,  therefore,  absolutely  distinct 
from  that  of  the  intervillous  spaces,  as  was  proved 
by  William  Shippen  in  1761,  and  the  interchange 
of  gases,  water,  and  nourishment  must  take  place 
through  the  villus-wall,  by  osmosis  and  by  the  vital 
action  of  the  cells  themselves,  particularly  the 
latter.  The  villus-wall  consists  of  the  following 
layers,  naming  them  from  within  outward:  endo- 
thelium of  capillary,  reticular  mucoid  stroma, 
Langhans'  layer,  syncytium,  both  of  the  latter 
from  the  fetal  epiblast.  Later  in  pregnancy  Lang- 
hans' layer  disappears  or  thins  out;  the  syncytial 
band  also  grows  narrower,  until,  at  term,  the  villus 
has  only  a  single  layer  of  the  stretched  syncytium 
over  it  (Fig.  60). 

The  Development  of  the  Amnion  and  Umbilical 
Cord. — According  to  the  latest  researches  of  Graf  Spee, 
the  amnion  in  the  human  is  formed  in  a  manner  similar 
to  that  of  many  mammals.  Very  early  a  split  appears  in 
the  epiblast  of  the  germinal  area;  this  fills  with  fluid  and 
forces  the  embryonic  plate  toward  the  center  of  the  egg. 
The  mesoblast  grows  rapidly  and  separates  this,  the  primary 
amniotic  cavity,  from  the  epiblast,  all  over  except  at  the 
area  of  insertion  of  the  abdominal  pedicle,  at  the  same  time 
itself  splitting  into  two  layers — the  somatoplcure,  external; 
the  splanchnopleure,  internal.  A  fluid  appears  in  the  space 
between  them,  which  is  called  the  exocelom,  and  takes  in  almost  the  entire  content  of  the  egg  at  this 
time.  By  the  development  of  the  exocelom  the  entoderm  is  separated  from  the  periphery  of  the  ovum

and  the  vitolline  sac  is  formed.  The  \'itelline  sac  is  developed  on  tlie  abdominal  side  of  the  embryo, 
while  the  amniotic  sac  is  formed  on  its  dorsal  aspect.  The  vitelline  sac,  consisting  of  a  layer  of  endo^ 
blast  and  one  of  mesohlast,  and  containiiiK  albuminoid  matter,  at  first  is  nmch  the  larger"  later  the 
amniotic  cavity  is  larger.  Tlie  vitellus  communicates  broadly  with  the  primitive  intest'inal  tube 
and  has  l)lood-ve.ssels,  the  vasa  ompliaiomcseaterica,  which  convey  the  nourishment  contained  in 
the  vitelline  sac.  The  contiiuicd  dcvcloijinent  of  the  cavity  of  the  aimiion  and  the  closing  in  of 
the  lateral  walls  of  the  eml)ryo  force  the  viteliin(>  sac  to  as.sume  the  shape  of  a  pedunculated  vesicle, 
and  as  its  contents  are  absorbed,  it  shrinks  until,  at  the  end  of  the  si.xth  week,  it  is  represented 
only  by  the  thin  ductus  omphalomesentericus  and  the  umbilical  vesir-le.  These  structures  may 
often  be  found  on  the  full-term  placenta  between  the  chorion  and  airmion,  more  or  le.s.s  di.stant 
from  the  insertion  of  the  cord.  The  vesicle,  which  up  to  the  fom-th  month  mea.sure.s  7  to  10  mm., 
is  then  the  size  of  a  split-pea,  yellow  and  fibrous,  and  shows,  leading  from  it,  lost  in  the  cord,  a 
fine  white  thread,  the  relics  of  the  duct.  Sdiultze's  fold  is  a  dui)lication  of  amnion  (Fig.  0(3)  at 
the  point  where  the  original  oiiiphaloinesenteric  duct  left  the  abdominal  pedicle. 

The  vitelline  circulaticjn  ceases  as  the  sac  shrinks,  and  as  the  embryo  receives  it.s  nourish- 
ment from  the  chorion  frondosum,  through  the  two  veins  and  two  arteries  of  the  abdominal  pedicle.

The  amniotic  cavity  enlarges  rapidly,  and,  coming  around  the  embryo  from  all  sides,  causes  the 
disappearance  of  the  exocclom,  and  forces  the  alidominal  pedicle,  with  its  rudimentary  blind 
allantoic  stalk,  and  the  four  blood-vessels,  and  the  omphalomesenteric  duct  together  into  a  single 
short  peduncle,  the  l)eginning  of  the  umbilical  cord.  This  occurs  in  the  fourth  week,  and  the  am- 
nion completely  fills  the  egg  in  the  second  month,  coming  to  lie  on  the  chorion  throughout  its 
extent.  The  embryo  now  floats  freely  in  the  cavity  of  the  anniion,  surroundeil  by  the  fluiti  there 
produced,  the  liquor  amnii.  and  united  to  the  chorion  frondosum  l)y  the  umbilical  cord.  It  i.s 
nourished  by  the  blood  which  circulates  between  it  anil  the  chorion  frondosum.  The  nutritional 
organs  are  all  formed  as  they  will  continue  throughout  pregnancy,  reciuiring  only  further  enlarge- 
ment to  acconnnodate  the  rapidly  growing  fetus.  (For  further  details  the  reader  is  referred  to 
text-books  on  embryology.  The  al)Ove  flescription  was  necessary  for  the  proper  study  of  the 
clinical  side  of  conditions  met  daily  by  the  obstetric  practitioner.) 

The  placenta  at  term  is  a  cako-liko  organ,  and  wciRhs  about  500  gm.,  the 
proportion  to  the  weight  of  the  chihl  being  as  one  to  ?ix.  Phieenta.s  vary  in  weight, 
size,  thickness,  form,  and  consistence  (Fig.  69).  Phicentas  from  hirge  children  are 
heavier.     In  syphiHtic  eases  the  placenta  is  heavier  than  with  normal  children  of

the  same  size,  and  the  proportion  may  l)e  reduced  to  one  to  three.  A  placenta  may 
be  small  and  thick  or  large  and  thin,  the  usual  thickness  being  13^  to  2  cm.,  and  the 
breadth  15  to  18  cm.  The  form  is  usually  irregularly  round,  but  the  organ  may 
assume  any  shape,  depending  on  its  direction  of  groAA-th  on  the  uterine  wall.  Bilo- 
bate  (the  usual  shape  is  apes),  trilobate,  and  horseshoe  shapes  are  observed,  and

the  placenta  may  be  spread  out  over  a  large  area — placenta  mem])ranacea.  In  ad- 
dition to  a  main  placenta,  there  may  exist  accessory  portions  connected  to  the  former 
by  an  artery  and  vein;  these  are  called  placentse  succenturiatse,  or,  if  very  small, 
placentulse  succenturiatse.  If  no  blood-vessels  can  be  seen,  the  piece  is  termed  a 
placenta  spuria.     These  extra  placentas  are  of  immense  clinical  importance.     The

shape  of  the  placenta  depends  on  the  first  location  of  the  ovum  after  it  enters  the 
uterus.  If  the  ovum  attaches  itself  to  the  center  of  either  the  anterior  or  the 
posterior  wall,  the  placenta  probably  will  be  round  or  oval.  If  it  is  embedded 
near  one  of  the  lateral  angles  of  the  uterus,  the  decidua,  being  tliin  at  this  point, 
offers  poor  nourishment  to  the  villi,  which  then  grow  eccentrically,— either  on  to 
the  fundus  or  on  to  the  other  Avail  of  the  uterus,— a  Ijilobate  or  a  trilobate  placenta 
resulting.  Such  a  division  into  lobes  may  also  result  from  the  pathologic  formation 
of  fibrinous  masses  in  the  placenta.

Some  placentas  are  soft  and  very  vascular;  others  are  harder  and  more  fibrous, 
■without  being  pathologic.  The  tissue  of  the  organ  is  dark  red.  soft,  friable,  but 
interwoven  Avith  tough  fibrous  tissue  and  blood-vessels.  The  maternal  surface — 
that  surface  which  lies  on  the  wall  of  the  uterus— is  covered  with  a  thin,  grayish, 
translucent,  slightl>'  roughened  membrane,  which  cannot  be  peeled  off,  but  tears 
aAvay  from  the  underlying  soft  pulp  of  the  placenta.  This  is  that  part  of  the 
decidua  serotina  callecl  the  compacta,  and  which  normally  separates  from  the 
spongiosa  and  comes  away  with  the  placenta  when  it  leaves  the  uterus.  Tliis

thicker  and  opaque.     At  the  rim  of  the  placenta,  and  extending  a  Httle  under  the 
amnion,  the  decidua  accumulates,  the  closing  ring  of  Waldeyer,  or  the  decidua

subchorialis.  If  you  scrape  into  this  area,  you  will  find  a  large  sinus,  the  circular 
or  marginal  sinus,  and  it  may  be  followed  all  around  the  circumference  of  the  pla- 
centa.    (See  Fig.  55,  p.  42.) 


Fig.  GS. — Normal  Placenta   (Maternal  Surface). 


The  maternal  surface  of  the  organ  is  divided  by  decidual  septa  into  numerous 
lobes  called  cotyledons.     If  one  pushes  the  cotyledons  asunder,  the  septum  is

split,  and  the  arterial  sinuses  which  lead  into  the  intervillous  spaces  are  disclosed. 
(See  Fig.  57,  p.  43.)  Occasionally  a  cotyledon  will  he  sessile  <jn  the  surface  of  the 
placenta,  and  may  be  left  in  the  uterus.  The  most  careful  examination  of  the 
delivered  placenta  will  fail  to  discover  the  absence  of  such  a  piece,  and  serious 
illness  of  the  mother  may  result  from  its  retention,  such  as  hemorrhage  or  sejisis. 

The  fetal  surface  of  the  ]ilacenta  is  covered  by  the  thin,  glistening  amnion, 
through  which  one  sees  the  i)lacental  arteries  and  veins  coming  from  the  cord  and 
branching  in  all  directions  until  the  smallest  twigs  disappear  about  one-fourth  of 
an  inch  from  the  edge  of  the  placenta.  The  surface  is  uneven,  gray,  and  reddish, 
sometimes  dotted  with  whitish  and  yellowish  areas  of  fibrous  tissue.     These  are

called  white  infarcts,  are  very  common,  and  will  be  considered  under  the  pathology' 
of  the  placenta  (p.  551).  The  amnion  may  be  strii>]ied  off  the  fetal  surface  except 
at  the  insertion  of  the  cord.  It  is  attached  only  by  the  jelly  of  \\'harton.  In  rare 
cases  the  anmion  may  be  stripped  off  the  cord  also,  the  jelly  of  Wharton  being 
pn^sent  here  too.  The  chorion  la?ve,  that  portion  of  the  i)erii)hery  of  the  ovum 
which  lay  against  the  decidua  refiexa,  and  in  which  the  villi  have  atrophied,  together 
with  the  amnion,  forms  a  veil-Hke  structure  hanging  from  the  placenta,  and  called 
the  membranes.  The  chorion  is  the  outer  layer,  thicker,  cloudy,  somewhat  opaqu(\ 
and  easilv  torn.  On  its  maternal  surface  are  the  remains  of  the  decidua  vera  an<l 
reflexa,  whicii  can  be  scraped  off  with  the  finger-nail  as  debris.  Early  in  pregnancy

and  in  pathologic  cases  it  is  a  thicker  membrane.  Occasionally  one  sees  blood- 
vessels running  in  the  decidua,  especially  in  the  neighborhood  of  the  placenta. 
The  amnion  is  tougher  and  transparent. 

The  umbilical  cord  is  inserted  about  ,the  middle  of  the  placenta,  but  it  may  be 
found  at  any  point — at  the  edge  (insertio  marginalis)  or  even  in  the  adjacent  mem-

branes  (insertio  velamentosa) .  At  its  insertion  are  occasionally  found  small 
epithelial  amniotic  growths  or  caruncles,  also  the  fold  of  amnion,  carrying  the 
ductus  omphalomesentericus,  Schultze's  fold.  At  some  point  in  the  membranes 
there  is  an  opening  through  which  the  fetus  passed.     This  lies  usually  10  cm.  from

the  edge  of  the  placenta,  showing  that  such  was  the  distance  from  the  internal  os 
of  the  uterus  to  the  edge  of  the  placenta.  The  opening  may  be  close  to  the  edge, 
which  shows  that  the  placenta  lay  near  the  internal  os,  or  even  over  it — placenta 
praevia.  The  placenta  is  situated  usually  on  the  anterior  or  the  posterior  wall  of 
the  uterus,  seldom  over  the  internal  os  (placenta  prsevia),  and  most  rarely  in  the

fundus.  It  may  lap  over  from  one  side  to  the  other.  The  causes  of  particular 
insertions  of  the  placenta  are  unknown.  Endometritis  and  subinvolution  certainly 
have  something  to  do  with  the  location  of  the  placenta  low  in  the  uterus. 

The  umbilical  cord  connects  the  fetus  with  the  placenta,  and  is  the  means  of 
conveyance  of  tlie  fetal  ])lood  to  and  from  the  latter.  It  is  formed  bj-  the  abdominal 
pedicle  of  the  embryo,  as  was  described  on  p.  45.  The  amnion,  as  it  develops, 
surrounds  the  cord,  but  is  not  attached  to  it.     This  occurs  later.     On  cross-section 


Fig.  73. — Placenta  Scccextctiiata. 

the  cord  shows  the  covering  of  amnion  epithelium,  two  arteries  (sometimes  one) 
and  one  vein  (sometimes  two),  the  relics  of  the  om])lialonu'senteric  duct  (often 
lost),  remains  of  the  allantois,  the  jelly  of  Wharton,  which  binds  all  together.  If 
there  is  much  jelly  of  "WTiarton,  we  speak  of  a  fat  cord;  if  little,  of  a  lean  cord. 
The  amnion,  ^\'ith  its  pavement  epithelium,  passes  over  into  the  skin  of  the  fetus 
at  the  navel,  where  there  is  a  sharp  line  of  demarcation  between  them.  A  plexus 
of  capillaries  ascends  the  amnion  for  one-eighth  of  an  inch,  but  there  are  no  blood- 


FlG.    74. RaTTLEDORK    ri.A(j:NT\. 

vessels  in  the  cord  except  those  mentioned.  \'asa  jiropria  do  not  exist  here,  but 
they  do  in  the  vessels  of  the  placenta.  Nerves  were  not  fountl  by  \'irchow  and 
most  searchers,  but  KoUiker  and  Valentine  found  them.  At  first  the  cord  is  very 
short,  but  as  the  child  grows  it  lengthens  until,  at  term,  it  meiisures  about  50  cm. 
This  varies  from  a  few  millimeters  to  300  cm.  A  l(>ngth  of  over  100  cm.  is  ver>- 
rare.  The  spiral  twists  in  the  cord,  of  which  there  may  i)e  several  hundred,  are 
best  explained  bv  the  movements  of  the  child,  ])ut  the  direction  of  the  growth  of 
the  arteries,  and'the  effect  of  the  pumping  action  of  the  fetal  heart,  may  be  partly

causative.     Stowe  found  that  the  tensile  strength  of  the  cord  was  from  8  to  15 
pounds. 

The  umbihcal  arteries  are  continuations  of  the  hypogastric  vessels;  the  vein 
conies  from  the  umbilical  vein.  The  arteries  are  twisted  on  themselves;  they  are 
twisted  around  the  vein,  and  the  vein  is  also  twisted,  and,  as  a  result,  there  seem 
to  be  valves  in  the  vessels,  called  valvules  hobokenii.  The  arteries  usually  anasto- 
mose near  the  placenta.  In  6  per  cent.  (Hyrtl)  only  one  umbilical  artery  exists. 
They  have  a  strong  middle  coat.  The  arteries  and  vein  are  sometimes  curled  into 
nodes  which,  covered  by  the  jelly  of  Wharton,  form  the  so-called  false  knots  on 
the  cord.     True  knots  are  also  found. 

The  Amnion  and  Liquor  Amnii. — The  thin,  transparent,  silvery,  tough  mem- 
brane lining  the  chorion  licve  and  frondosum  (placenta)  is  the  amnion.  Its  forma- 
tion has  already  been  considered.  (See  p.  44.)  Occasionally  a  little  of  the  jelly 
of  Wharton  exists  between  i:iie  two  structures.  The  liquor  amnii  is  produced  by 
the  amnion  at  the  very  earliest  period  of  fetation,  and  at  first  it  is  crystal  clear; 
later  it  becomes  more  opaque.     The  amount  at  full  term  varies  from  500  to  2000  gm., 

depending  on  many  conditions,  one 
of  which  is  the  size  of  tlie  child,  an- 
other multiparity — more  liciuor  in 
each  instance.  Quantities  less  than 
500  gm.  and  more  than  2000  are 
pathologic,  the  former  being  called 
oligohydramnion,  the  latter  poljdiy- 
dramnion.  The  amount  of  the  fluid 
increases  up  to  the  seventh  month; 
from  then  on  it  regularly  decreases 

fV  y"}l'  ]      until,  at  term,  there  is  usually  but 

\^  "}'■■  #'  /      enough  to  fill  out  the  spaces  between 

\  /        the  irregular  contour  of  the  fetus  and 

the  uterine  wall.  It  is  a  clear  fluid, 
more  or  less  milky  from  suspended 
particles  of  vernix  caseosa.  This  is 
the  accumulated  and  exfoliated  epi- 
dermis, sebaceous  matter,  and  lanugo 
from  the  skin  of  the  child.  There  are 
also  some  leukocytes  and  unclassified 
cells.  If  the  fetus  dies,  the  liquor 
amnii  becomes  blood  stained,  and  if 
the  child  is  asphyxiated,  one  finds  it  green  and  thick  from  the  admixture  of  meconium. 
It  has  a  peculiar  sperma-like  odor,  and  a  specific  gravity  varying  from  1006  to  1015, 
which  diminishes  as  pregnancy  advances.  The  reaction  is  faintly  alkaline  or  neutral. 
The  cryoscopic  (freezing)  point  of  the  liquor  amnii  is  slightly  higher  than  that  of 
the  maternal  blood  (A  0.56).  Therefore,  speaking  generally,  the  liquor  is  destined 
to  be  absorbed  (Keim).  Clinically,  one  can  observe  fluctuations  in  the  amount  of 
liquor  amnii.     At  the  seventh  month  a  sudden  increase  may  often  ])e  noted. 

The  chemic  analyses  of  liquor  amnii  vary  considerably.  Prochownik  found

DEVELOPMENT    OF   THE    OVUM  53 

Sandmeyer  examined  tlie  liciuor  aiiinii  witli  a  view  to  detoriiiininK  it.s  food  value,  and  found 
it  contains  an  average  of  U.22  j)er  cent,  of  albuniin.  The  salts  are  in  about  tlie  same  proportion  as 
human  Ijlood-serum,  i.  e.,  O.o  per  cent.,  and  are  the  chlorids,  phosphates,  sulphates,  and  carbonates 
of  .sodium  and  calcium,  with  vvvy  little  pota.s.sium. 

An  important  hnding  is  urea,  which  was  found  })y  Prochownik  as  early  as  tlie  fourtli  week, 
and  whicli  increases  toward  the  end  of  ])n>gnancy  and"  witli  the  size  of  the' fetus.  The  amount 
varies  from  0.02  to  0.4  per  cent.  Ahlfeld,  in  a  case  where  the  bag  of  waters  had  ruptured  thirty- 
one  days  before  labor,  could  find  so  little  urea  in  the  collected  licjuor  anuiii  that  it  could  not  be 
measured.     Barnes  says  that  since  there  is  urea  in  the  egg,  the  fetus  must  excrete  it. 

The  albumins  in  the  liquor  are  serum-albumin,  ghjbulin,  and  an  ovovitellin-like  substance 
(Goenner). 

Bondi  found  pepsin,  a  diastatic  ferment,  a  fat-splitting  ferment,  and  one  like  fibrin-ferment 
in  the  lifjuor  amnii.  These  facts  are  important  in  connection  with  the  maceration  of  fetu.ses  after 
they  die.  In  diabetes  sugar  is  present  in  the  li(iuor.  Normally,  i)acteria  are  not  present,  but 
under  pathologic  conditions  they  may  wander  up  the  cervix  and  through  the  membranes,  or 
through  the  musculature  from  adherent  adjacent  organs,  e.  y.,  inflamed  bladder  and  appendix  or 
decomposing  fibroids. 

The  >Sourcrs  of  the  Liquor  Amtiii. — Xaturalh-,  the  li(}Uor  amnii  comes  ultimately  from  the 
mother,  but  much  discission  has  arisen  as  to  whether  the  fetus  excretes  it,  either  as  urine  or 
tiirougli  the  cord  and  fetal  placenta,  or  whether  it  pa.sses  directly  into  the  cavity  of  the  uterus 
from  tlie  maternal  vessels.  Probably  both  hypotheses  are  true.  In  favor  of  the  fiVst  theory  have 
been  adduced — (1)  Constant  presence  of  urea  in  the  liquor  amnii  (the  fetus  urinates  into  it);  (2) 
the  demonstration  of  urine  in  tlie  l)ladder  of  new-born  children;  (3)  the  occurrence  of  pf)lyhy- 
dramnion  when  the  fetus  has  heart  disea.se,  in  unioval  twins,  and  in  fetal  monsters.  In  the 
latter,  however,  one  must  remember  that  monstrosities  are  frecjuently  caused  by  amnionitis, 
wliich  may  also  cause  the  polj'hydramnion. 

The  theory  that  the  liquor  anmii  is  a  transudate  from  the  maternal  vessels  is  most  plausible. 
(1)  When  pota.s.sium  iodid  is  given  the  mother,  it  will  appear  in  the  liquor  amnii,  but  not  in  the 
fetal  kidney  (Haidlen).  In  diabetes  sugar  appears  in  the  liquor  anmii.  (2)  \\hen  the  mother 
has  heart  disease  or  any  affection  attended  by  dropsies,  one  will  often  find  an  increa.-;e  of  the  fluid. 
(3)  Early  in  pregnancy,  and  when  the  fetus  has  been  dead  for  some  time,  there  is  relatively  too 
much  fluid  in  the  uterus.  (4j  Wohlgemuth  and  Ma.s.sone  experimentally  showed  that  dia.sta.se  in 
the  maternal  blood  ai)pears  in  the  li(iuor  amnii  when  the  fetus  is  dead.  (r>)  Polano  believes  the 
liquor  is  a  secretion  of  the  amniotic  epithelium,  and  since  pathologic  changes  in  the  amnion  have 
been  found  in  cases  of  hydramnion,  color  is  lent  to  this  view.  That  the  fetus  urinates  into  the 
liquor  amnii  is  improbable.  If  urea  was  excreted  in  this  fashion,  more  of  it  should  be  found,  and 
it  is  unreasonable  to  suppose  that  natiu'e  would  have  an  individual  floating  in  and  drinking  its  own 
excreta.  Cohnstein  and  Zuntz  have  proved  that  the  arterial  pressure  in  the  kidney  is  too  low 
even  for  the  protluction  of  urine.  Ahlfeld  pro\('s  almost  conclusively  that  the  fetus  does  not, 
normally,  urinate  into  the  licjuor  amnii;  that  when  tiiis  does  occur,  it  is  accidental,  and  probably 
due  to  some  more  or  less  serious  circulatory  disturbance. 

In  a  ca.se  where  I  administered  methylene-blue  to  the  mother  before  labor  it  was  excreted  by 
the  new-born  cliild  in  the  urine  for  se^•eral  days  after  birth,  but  the  licjuor  anmii  was  not  blue. 

The  Uacs  of  ihe  Liquor  Atnnii. — Tlie  fluid  aroinid  the  child  has  most  important 
functions:  1.  First  it  is  a  food,  which  the  fetus  drinks.  This  is  proved  by — (a)  The 
finding  of  lanugo  in  the  meconium  after  birth,  and  real  swallowing  motions  have 
been  determined  in  the  fetus  during  the  latter  months  of  jiregnancy.  (6)  In  a  case 
of  occlusion  of  the  gullet  the  fetus  was  atrophi(Ml.  (c)  The  liquor  anmii  contains 
albumin  constantly,  and  if  the  fetus  drinks  enough,  it  will  get  a  considerable  amount 
of  albumin. 

2.  It  is  a  water-cushion  taking  up  the  shocks  from  external  injury,  and  allowing 
free  motion  to  the  fetus;  this  jirevents  deformities,  e.  g.,  clul)-foot.  In  ca.>^es  wiiere 
the  liquor  is  very  scant  the  child  is  folded  comjjactly  together,  and  shortening  of  the 
muscles,  wTy-neck,  and  various  distortions  of  the  extremities  result. 

3.  It  prevents  the  amnion  from  adhering  to  the  fetus  and  causing  deformities, 
e.  g.,  harelip,  hcmicephalus,  amputations,  imperfect  closure  of  the  body  cavities, 
all  examples  of  arrest  of  develojiment  due  to  strands  of  anuiion,  called  Simonart's 
bands.  It  preserves  the  cord  from  pressure  ami  renders  the  movements  of  tlie 
child  less  painful  to  the  mother. 

4.  During  labor  it — (a)  Helps  dilate  the  passages  by  forming  a  fluid  wedge  with 
the  membranes,  and  (b),  surrounding  the  fetus  com]il(>tely.  it  distributes,  a.s  all 
fluids  dp,  the  compression  exerted  by  the  contracting  uterus,  equally  in  all  directions, 
and  thus  saves  any  part  of  the  fetus  from  injurious  pressure.  When  the  liquor  amnii 
has  been  discharged,  the  fetus  is  ex-posed  to  this  i)ressure  and  may  succimil)  to  it. 
By  the  same  action  the  placenta  is  held  against  the  uterine  wall,     (c)  It  washes  out

the  vagina  for  the  passage  of  the  child,  and  by  its  shghtly  bactericidal  action,  pre- 
vents infection  of  the  child  and  the  uterine  cavity.  Unfortunately,  this  antiseptic 
action  is  weak.

curve,  of  the  fetus.  It  is  impossible  to  obtain  these  figures  with  scientific  accuracy,  first,  because 
the  exact  date  of  conception  cannot  be  determined  in  any  of  the  cases,  and,  second  the  mdividuals 
vary  in  utero  as  thev  do  after  birth.  A  good  rule,  which  for  practical  purposes  will  suffice  tor  the 
determination  of  the  length  of  the  fetus  at  a  given  period  of  pregnancy,  is  tins:  bquare  the  number

of  the  month,  which  will  give  the  length  of  the  fetus  in  centimeters  until  the  fifth  month.  After 
the  fifth  month  add  to  this  five  each  month;  thus  at  four  months  a  fetus  should  l>e  about  IG  cm. 
long;  at  six  months,  30  cm.  (5X5  +  oj;  at  seven  months  (5X5 +  0  +  0),  and  so  on.  The  length  of 
the  fetus  is  the  safest  guide  in  the  determination  of  its  age.  Children  vary  both  in  length  and 
weight.  Some  babies  grow  faster  than  others,  and  too  their  growth  may  be  interrupted  tempo- 
rarily during  pregnancjj.     rrctjuont  examinations  during  gestation  will  show  this. 

The  Fetus  at  Various  Periods. — The  best  work  on  the  early  human  ovum  was  done  by 
His,  and  from  his  "Atlas  der  Anatomie  menschl.  Embryonen,"  Leipzig,  1882,  the  following  pictures 
are  taken  (Figs.  78  and  79).  His  distinguished  three  periods  in  the  life  of  the  child — the  ovular, 
during  the  first  two  weeks;  embryonal,  the  third,  fourth,  and  fifth  weeks;  and  fetal,  from  that  on 
until  term.  The  ovum  in  the  fir.st  weeks  interests  the  practical  obstetrician  little,  l)ecau.se  it  can 
be  studied  only  with  a  microscope.  It  is  almost  impo.ssible  to  judge  the  age  of  the  little,  shaggy, 
bladder-like  ova  that  are  expelled  in  early  abortions,  liecause  they  are  often  pathologic.  .\s  a 
general  rule,  however,  an  ovum  the  size  of  a  pigeon's  egg  is  four  weeks,  and  one  the  size  of  a  hen's

egg,  six  or  seven  weeks.  After  this  period  the  length  of  the  fetus  from  nape  of  neck  to  sacrum,  and 
still  later  the  total  length,  give  more  certain  conclusions.  .•,•.• 

End  of  the  First  Lunar  Month.— An  embrvo  of  this  period  is  <  •  2  to  9  mm.  lon^,  ha.s  mdications 
of  nose,  eyes,  and  ears.  The  stumps  of  the  extremities  are  fairly  long,  and  show  rudiments  of  fingers 
The  head  and  tail  ends  are  almost  in  contact,  separated  only  by  the  stalk  of  the  vitelhne  sac  and 
the  abdominal  pedicle.  The  visceral  arches  are  distinct;  the  four  heart  cavities  are  developed; 
the  intestinal  canal  is  nearlv  closed,  and  first  indications  of  hver  and  kiiineys  appear. 

End  of  Second  Month.— The  fetus  is  2}  2  cm.  long;  the  branchial  arches  are  nrominent  at  the 
beginning  of  this  period,  but  disappear  at  its  end.  The  ear  appears,  an<l,  later,  the  eyelids.  1  he 
extremities,  at  first  bud-Uke  at  the  end.  show  the  division  into  three  parts:  first,  the  arm,  forearm, 
and  hand;  then  the  thigh,  leg.  and  foot,  and  the  digits  are  more  mark^i.  The  tail-hke  process  has 
di.sappeared.  The  navel  begins  to  clo.-^e;  the  liver  develops,  also  the  abdomen  which  is  not  yet 
quite  closed,  and  the  external  genitals  appear,  but  it  is  impo.ssible  to  determine  the  sex  of  the  fetus, 
since  the  male  and  female  genitaUa  are  developed  from  identical  organs  and  are  differentiated  later. 


56  PHYSIOLOGY    OF    PREGNANCY 

The  \'illi  in  the  decidua  serotina  grow  luxuriantlj^,  forming  the  future  placenta,  the  perma- 
nent fetal  maternal  relations  being  now  fully  established. 

End  of  Third  Month. — The  ovum  is  a  little  larger  than  a  goose-egg,  and  the  fetus  7  to  9  cm. 
long,  weighing  5  gm.  at  the  beginning  and  20  gm.  at  the  end  of  the  month.  The  navel  is  closed, 
the  internal  genitals  differentiated.  The  external  genitals  are  alike  in  the  two  sexes.  At  the 
beginning  of  the  eleventh  week  the  scrotum  closes,  and  the  sex  may  be  determined.  The  intestinal 
canal  is  formed  and  contains  bile  (Zweifel).  The  body  resembles  a  human  being,  though  the  head 
is  still  proportionately  extremely  large.     Centers  of  ossification  are  visible  in  many  of  the  bones. 

End  of  Fourth  Month. — The  fetus  is  10  to  17  cm.  long,  and  weighs  120  gm.  at  the  end  of  this 
period.  Meconium  is  present  and  is  turning  green  (Charpentier).  The  muscles  are  active,  fetal 
movements  being  occasionally  felt  by  the  mother.  The  heart-beat  is  strong  and  has  been  heard. 
The  external  organs  of  sex  can  easily  be  differentiated.  The  skin  is  bright  red,  transparent,  so 
that  all  the  vessels  are  visible.     Lanugo — fine  hair — appears  on  the  skin. 

Fifth  Month. — The  fetus  is  now  from  17  to  26  cm.  long,  and  weighs  250  to  280  gm.  (7  to  9 
ounces).  The  head  is  still  very  large,  being  the  size  of  a  hen's  egg,  but  the  abdomen  is  less  promi- 
nent. The  fetus  is  lean.  The  skin  is  still  red,  but,  owing  to  the  deposition  of  fat,  is  less  trans- 
parent. The  lanugo  is  present  all  over  the  body,  but  on  the  head  there  are  indications  of  hair. 
The  nails  can  be  distinguished.  The  eyelids  are  closed.  Such  a  fetus  may  live  for  five  to  ten 
minutes  -with  strong  heart-beat  and  attempts  at  respiration. 

Sixth  Month. — The  fetus,  at  the  end  of  the  sixth  month,  is  28  to  34  cm.  long  and  weighs 
about  645  gm.  (134  pounds).  Its  body  is  more  in  proportion,  though  still  lean,  the  amount  of  fat 
in  the  skin  being  still  small.  The  skin  is  wrinkled,  and  vernix  caseosa  begins  to  form.  This  is  the 
accumulated,  exfoliated  epithelium  and  sebaceous  secretion.  The  eyebrows  and  lashes  are  formed; 
the  eyelids  are  separated,  and  such  an  infant  born,  may  breathe,  though  superficially,  and  live  for 
several  hours  under  favorable  conditions.  Since  its  respiratory,  digestive,  and  assimilative  organs 
are  undeveloped,  no  artificial  means  will  preserve  these  fetuses  from  congelation  and  starvation. 
Reports  of  the  rearing  of  such  infants  are  to  be  discredited. 

Seventh  Mo/ii/i.— Length,  35  to  38  cm.;  weight,  1000  to  1220  gm.  (around  2}4  pounds). 
The  infant  looks  like  a  dried-up  old  person,  with  red,  wrinkled  skin.  The  wrinkles  fill  out  with 
fat  and  disappear,  but  in  later  life  or  in  illness  they  develop  again  in  the  same  form  and  distribu- 
tion. One  can  often  trace  family  traits  through  these  wrinkles.  The  eyes  are  opened;  the  tes- 
ticles sometimes  have  entered  the  scrotum.  The  cliild  cries  with  a  weak  whine  or  grunt,  but,  since 
the  lungs  are  not  developed,  it  can  seldom  be  kept  alive.  Rarely,  an  infant  at  seven  months  of 
gestation  is  as  far  advanced  as  another  at  eight  months,  and  can,  of  course,  survive.  Those  chil- 
dren of  the  early  part  of  tliis  period  which  the  auihor  has  succeeded  in  raising  have  in  later  years 
not  given  him  much  satisfaction,  haAdng  nearly  all  become  hydrocephalic,  dwarfed,  or  paralytic. 
From  the  twenty-seventh  to  the  twenty-eighth  week  not  a  few  have  been  saved  and  are  growing 
promisingly. 

Eighth  Month. — The  child  is  now  43  cm.  long,  and  weighs  around  1600  gm.  (SH  to  4  pounds). 
The  papillary  membrane  has  disappeared.  The  skin,  though  still  red,  is  not  so  much  wrinkled, 
and  the  child  is  less  lean.  Vernix  caseosa  and  lanugo  are  still  present.  The  testicles  are  usually 
in  the  scrotum.  The  bones  of  the  head  are  soft  and  flexiljle;  o.ssification  begins  in  the  lower 
epiphysis  of  the  femur.  Meconium  is  passed  with  difficulty.  Crying  is  stronger,  but  some- 
times only  a  whimper.  Such  children  may  generally  be  reared,  with  the  aid  of  maternal  milk, 
good  nursing,  and  a  proper  incubator. 

Ninth  Month. — Weight,  about  2.500  gm.  (around  5}4  pounds);  length,  46  to  48  cm.  The 
lanugo  begins  to  disappear  from  the  face  and  abdomen,  the  redness  fades,  the  wrinkles  smooth  out, 
the  panni(;ulus  adiposus  develops,  the  limbs  become  rounded.  The  nails  are  at  the  tips  of  the 
fingers.  Circulatory,  respiratory,  and  digestive  organs  are  now  well  developed,  though  the  child 
requires  good  care  for  a  successful  extra-uterine  existence. 

Tenth  Mordh. — Weight,  3100  gm.  (7  to  73x'2  pounds);  length,  48  to  50  cm.  Ahlfeld  says  the 
fetus  may  lose  a  little  after  the  fortieth  week.  At  the  end  of  this  period  the  child  is  prepared  to 
cope  with  the  factors  of  an  extra-uterine  existence.     It  is  "ripe"  or  "at  full  term." 

The  Fetus  at  Term. — A  fully  developed,  ripe  fetus  presents  the  following  signs 
of  maturity:  length,  50  cm.;  weight,  3200  gm.  (7  to  7}/^  pounds);  the  skin  is 
white  or  pink,  a  fleshy  red  denoting  prematurity;  vernix  caseosa  is  thick  in  the 
creases  and  around  the  shoulders  and  back;  the  hair  is  several  centimeters  long; 
the  lanugo  mostly  gone;  the  finger-nails  are  firm  and  protrude  beyond  the  finger- 
tips and  to  the  tips  of  the  toes ;  the  panniculus  adiposus  is  well  developed ;  the  milia 
and  comedones  around  the  nose  have  usually  disappeared;  the  chest  is  prominent; 
the  mammary  glands  project;  the  navel  is  at  the  middle  of  the  belly,  and  two  or 
three  centimeters  below  the  middle  of  the  body  (higher  in  boys  than  in  girls) ;  the 
testicles  are  in  the  scrotum;  in  girls  the  labia  majora  cover  the  minora;  the  ear 
stands  out  from  the  head,  its  cartilage  being  well  developed;  the  bones  of  the  head 
are  hard,  the  sutures  narrow;  the  circumference  of  the  heg^d  is  equal  to  or  less  than 
that  of  the  shoulders  (Frank) ,  the  voice  is  loud  and  strong^  sucldng  movements  are 
vigorous  and  sustained;   meconium  is  passed  early  and  often.

At  autopsy  one  finds  other  si^ns  of  maturity  in  the  advanced  ossification  of  the 
bones,  e.  g.,  the  ossification  cent(^r  in  the  lower  end  of  the  femur  is  7  to  8  mm.  broad, 
and  the  cerebral  convolutions  resemble  those  of  the  adult  brain,  von  Winckel 
found  the  size  of  the  liver  and  other  organs  a  guide  to  the  age  of  the  fetus.  The 
size  and  develoinnent  of  the  i)lacenta  and  cord  are  unrelial)le  indices  of  maturity. 
Vascularity  of  the  decidua  at  the  border  of  the  placenta  is  usually  a  sign  of  i)re- 
maturity  of  the  ovum,  but  endometritis  must  be  excluded.  Ahlfeld  found  scratch- 
marks  on  the  amnion  made  by  the  fetus  after  its  nails  had  grown  beyond  the  finger- 


FiG.  80.— X-Ray  of  FExrs,  EioHTn   Month.     Length,  4.5  rv.;  Weioht,  li  I'ound.'*,  .s'2  Ounces. 


tips.  This  might  be  useful  in  medicolegal  cases  to  determine,  from  the  secundines, 
if  the  puerpera  had  delivered  a  viable  infant.  (See  v.  Winckel's  Ilandbuch  for  an 
exhaustive  consideration  of  this  subject.) 

Not  any  one  of  all  these  signs  is  absolutely  relial)le.  The  most  certain  is  the 
length  of  the  fetus,  but  even  this  varies  from  48  to  o2  cm.,  while  children  of  55  to 
62  cm.  have  frequently  been  delivered.  The  weight  of  the  fetus  is  e^specially  un- 
certain, as  a  nine  montlis.',  jin^gnancy  may  produce  a  child  of  only  1700  gm.  (3H 
pounds),  while  one  of  eight  months  may  develop  an  infant  of  3840  gm.  (8  pounds). 
Hodge  (1850)  taught  that  well-matured  children  are  sometimes  born  before  full 


58  PHYSIOLOGY    OF    PREGNANCY 

term,  and  Parvin  mentions  a  case  of  an  infant  weighing  7  pounds  delivered  after  less 
than  two  hundred  and  twenty-six  days  of  gestation. 

Some  children  at  term  or  over  term  are  small  and  puny  because  of  general  de- 
biUty  of  the  mother  or  sickness  during  pregnancy.  A  prolonged  febrile  disease,  for 
instance,  typhoid,  during  pregnancy  will  compromise  the  growth  of  the  fetus,  as 
also  w^ll  chronic  diseases,  diabetes,  heart  disease,  tuberculosis,  the  various  anemias, 
and  sjTphilis.  Bright's  disease  is  particularly  unfavorable,  since  the  placenta  is 
frequently  infarcted  (le  placenta  albuminurique)  and  its  nutritional  function  inter- 
fered wdth. 

Diseases  and  abnormal  location  of  the  placenta  restrict  the  growth  of  the  child. 
The  children  in  placenta  prsevia  are  usually  undersized.  Women  with  generally 
contracted  pelves  often  have  small  babies,  thus  giving  evidence  of  a  hereditary 
tendency  to  arrest  in  development.  La  Torre  finds  no  difference  in  size  in  the  chil- 
dren from  women  wdth  contracted  pelves  and  those  with  normal  pelves,  but  his  ob- 
servations were  mainly  on  rachitic  women.  Large  muscular  women  have  large 
babies,  and  the  same  is  true,  to  an  extent,  of  the  father.  The  head  of  the  child 
bears  a  certain  relation  to  that  of  the  father  and  mother.  Fat  women  usually  have 
large  babies.  Women  of  the  better  classes  have  larger  infants  than  the  needy  poor. 
Workers  in  factories  have  small  children,  and  in  some  European  countries  pregnant 
women  are  not  allow^ed  to  work  in  them  during  the  latter  months,  many  being  sent 
to  maternities  to  rest  during  the  period.  Statistics  have  shown  a  distinct  improve- 
ment in  the  general  health  of  the  mothers  and  a  gain  in  the  weight  of  their  infants 
since  this  practice  was  instituted.  Cigarmakers  and  workers  in  lead  and  phosphorus, 
if  abortion  and  premature  labor  do  not  occur,  have  puny  children.  Therapeu- 
tically, we  try  to  influence  the  size  of  the  child  by  dieting  the  mother  during  the 
latter  third  of  pregnancy.  (See  Prochownik's  diet.)  White  children  are  larger 
than  colored,  American  larger  than  European,  boys  larger  than  girls— 3  to  5  ounces. 
Children  born  in  wedlock  are  heavier  than  the  illegitimate;  this  may  be  due  to  the 
attempts  to  produce  abortion  which  many  such  women  make,  to  tight  abdominal 
constriction  practised  to  hide  the  evidence  of  pregnancy,  and  to  the  lack  of  proper 
nutrition  and  care  they  often  suffer. 

The  children  increase  in  size  in  successive  pregnancies,  which  is  due  to  the  better 
development  of  the  mother  which  comes  with  years,  the  more  active  circulation  in 
the  uterus,  and  the  prolongation  of  the  later  pregnancies.  The  first  child  is  likely  to 
be  small  or  thin,  since  it  often  comes  a  few  weeks  before  term ;  the  uterus  is  tense  and 
allows  little  freedom  of  movement,  and  the  health  of  women  in  their  first  pregnancy 
is  usually  not  as  good  as  in  the  subsequent  ones.  The  children  of  later  pregnancies, 
too,  are  better  developed  mentally  than  the  first  born.  Most  great  men  were  later 
children  in  large  families;  for  instance,  Benjamin  Franklin  was  the  seventeenth; 
Napoleon,  the  eighth;  Daniel  Webster,  the  seventh ;  Wagner,  the  seventh ;  Irving, 
the  eleventh;  Coleridge,  the  thirteenth,  child  of  their  parents.  After  the  eighth  or 
ninth  child  a  reduction  in  size  is  often  apparent,  due  to  a  decline  of  the  general 
health.  Children  from  women  after  a  long  period  of  sterility  are  smaller  than  usual, 
and  the  infants  of  young  girls  are  generally  undersized. 

If  the  child  is  carried  over  term,  which  is  not  seldom,  it  overgrows,  the  head 
hardens,  and  the  muscles  and  fat  become  firmer.  (See  the  chapter  on  Prolonged 
Pregnancy.) 

The  evidences  of  life  of  the  fetus  in  utero  form  an  interesting  study.  The  fetal 
heart  can  be  heard;  heart  and  funic  murmurs,  too;  one  can  feel  the  pulsation  of  the 
heart  through  the  alxlominal  w^all — all  of  which  will  be  considered  fully  under  the 
Diagnosis  of  Pregnancy.  The  fetus  moves  its  limbs  and  body  from  the  earliest 
months,  and  the  movements  are  audible  and  palpable  from  the  fifteenth  week. 
Often  one  sees  an  extremity  move  under  the  abdominal  wall,  and  sometimes  the 
legs  kick  out  with  considerable  force.     These  movements  may  be  so  active  that  they 


DEVELOPMENT   OF   THE    OVUM  59 

disturb  the  mother's  sleep  and  require  treatment,  such  as  a  tight  abdominal  binder 
and  a  dose  of  sodium  bromid.  1  he  child  has  periods  of  sleep,  of  rest,  and  of  activity. 
The  mother  may  notice  that  the  fetus  stretches  itself  after  a  period  of  quiet.  The 
author  has  felt  the  child  flex  or  extend  its  head,  withdraw  its  hand  when  the  member 
was  touched,  and  move  out  of  a  strained  i)osition  into  one  more  comfortable.  The 
infant  swallows  the  liquor  amnii  in  large  amounts,  lanugo  and  vernix  ca.seosa  having 
been  found  in  the  meconium.  These  swallowing  motions  have  never  been  diag- 
nosed. The  fetus  also  sucks  its  fingers  in  utero.  Ahlfeld  reports  a  case  where  the 
child's  thumb  was  swollen  at  birth,  and  it  immediately  i^ut  the  swollen  member  in 
its  mouth  and  sucked  it.  In  face  presentation  the  child  will  suck  the  examining 
finger.  One  of  the  most  interesting  phenomena  of  intra-uterine  life  is  fetal  hiccup. 
Hermann  first  described  it,  but  Ahlfeld  has  worked  up  the  subject.  The  author 
has  very  frequently  found  it,  and  many  intelligent  women  have  remarked  and 
correctly  diagnosed  the  phenomenon.  The  movements  are  short,  (|uick  jerks  of  the 
shoulders  and  trunk,  15  to  30  a  minute,  regular,  visible,  audible,  and  ])ali)able  to  the 
observer.  They  reseml^le  hiccups  perfectly  except  the  absence  of  stridor.  The 
author  has  heard  them  as  early  as  the  fifth  month  of  gestation.  They  ma}'  continue 
fifteen  to  twenty  minutes  and  become  very  annoying  to  the  mother,  recurring  at 
more  or  less  frequent  intervals  until  delivery.  In  one  case  the  author  heard  the 
sounds  distinctly  just  before  the  child  was  born,  and  within  a  minute  after  the 
child  was  delivered  it  was  hiccuping  so  loudly  that  it  was  heard  in  the  next  room. 
The  contraction  of  the  diaphragm  has  been  felt  by  the  hand  in  the  uterus  during  the 
operations  of  version  and  extraction,  but  it  was  impossible  to  be  sure  that  the  in- 
fant was  not  suffering  from  aspM-xia  and  was  gasping  for  breath.  The  latter  ex- 
planation of  such  a  movement  is  the  first  one  to  be  thought  of  in  cases  of  this 
nature. 

Another  phenomenon,  not  so  common,  and  more  uncertain  of  diagnosis,  is  the 
respiratory  action  of  the  child  in  utero.  If  one  carefully  observes  the  umbilical 
region  of  a  thin  woman,  pregnant  near  term,  one  ma>'  discover  fine  rising  and 
falUng  movements  of  the  abdommal  wall.  They  occur  CO  to  80  a  minute,  are  inter- 
mittent, and  are  most  pronounced  in  the  region  of  the  child's  chest.  Ahlfeld  has 
studied  these  motions  very  thoroughly,  and  is  convinced  that  they  are  due  to  minute 
excursions  of  the  fetal  chest,  and  he  has  succeeded  in  getting  graphic  tracings  of 
them  with  the  cardiograph,  showing  that  when  the  chest  expands,  the  abdomen  con- 
tracts. As  a  support  to  this  theory  one  may  add  the  daily  observations  of  the  new- 
born child.  Inspection  of  the  chest  will  show,  just  before  the  gasp  that  precedes  the 
first  cr}',  tiny  rapid  inspirations  and  expirations.  These  are  best  observed  on  the 
apneic  child  delivered  by  cesarean  section.  The  motion  in  utero  serves  to  strengthen 
and  prepare  the  diaphragm  and  chest  muscles  for  the  function  of  respiration,  but 
it  is  not  strong  enough  to  suck  liquor  amnii  further  than  the  pharynx,  whence  it 
probably  is  swallowed. 

The  Mental  State  of  the  Fetus  in  Utero.— A  child  shows,  very  shortly  after 
birth,  a  few  evidences  of  mental  action.  It  turns  its  face  toward  the  light ;  it  draws 
the  foot  or  arm  away  from  an  obstructing  object.  The  special  senses  are  all  present ; 
even  if  only  a  few  hours  old  it  makes  a  wry  face  when  a  solution  of  quinin  is  placed 
on  the  tongue;   a  loud  sound  causes  it  to  start;  it  feels  pain,  and  it  sees. 

The  mental  condition  of  the  fetus  in  utero  has  been  the  sul;ject  of  much  specula- 
tion. That  the  child  hcs  in  a  continuous  "dreamless  sleep"  (Parvin)  is  not  prob- 
able. Intelligent  mothers  have  said  they  could  distinguish  periods  of  sleep,  of  rest, 
and  of  activity.  The  child  will  assume  a  more  comfortable  attitude  after  it  is  dis- 
turbed by  external  manijjtilation.  During  lalior  it  will  wriggle  its  head  away  from 
the  examining  finger;  it  will  draw  its  hand  away  from  one's  grasp.  As  Bailly  said, 
it  is  probable  that  a  vague  and  obscure  will  intervenes  in  the  production  of  these 
movements.

CHAPTER  III 
THE  PHYSIOLOGY  OF  THE  FETUS 

This  is  a  now  science,  and  known  facts  arc  few,  tli()uji;h  many  liypotlicscs  have 
been  advanced  and  supported  by  deduction  from  the  study  of  the  lower  animals. 
The  ovum  is  not  a  part  of  its  mother,  but  simply  a  parasite,  possessing;  all  the  func- 
tions of  an  organized  being. . 

In  the  first  days  after  fertilization  the  ovum  prol)a))ly  is  nourished  by  osmosis 
and  imbibition  of  the  fluids  surrounding  it  in  the  tube,  ^^'hcn  it  reaches  the  uterus, 
the  trophoblast  is  already  developed,  and  these  cells  eat  into  the  uterine  mucosa. 
The  immense  development  of  the  decidual  cells  may  be  to  serve  as  nutriment  for  the 
ovTJm,  and  the  same  is  gotten  and  pn^pared  by  the  troj^hoblast.  The  glands  of  the 
uterus  enlarge  enormously,  and  are  filled  with  secretion,  as  is  shown  by  Fig.  41. 
This  secretion  has  fat  from  degenerated  leukocj'tes,  and  was  called  uterine  milk  by 
the  older  writers,  and  their  view  that  it  furnished  nourishment  to  the  ovimi  may 
not  be  Avithout  foundation,  though  in  the  human  placenta  the  villi  do  not  dip  into 
the  glands.  In  earliest  fetation  the  glands  around  the  ovum  contain  blood.  I'litil 
the  placental  circulation  is  established,  the  ovum  very  jirobably  is  nourished  in  the 
two  ways  indicated. 

The  Fetal  Blood. — The  blood  at  term  has  about  the  same  appearance  as  ma- 
ternal blood,  but  has  less  fibrin  and  hemoglo})in  and  more  salts  (Preyer).  It  con- 
tains hemolysin,  which  has  also  ))een  proved  to  pass  through  the  ])lacenta  from  the 
mother.  Its  blood  may  react,  as  does  its  mother's,  to  the  introduction  of  foreign 
albuminoids,  by  the  production  of  antibodies.  It  has  less  complement  than  the 
mother's  blood. 

The  nucleated  red  blood-corpuscles  have  all  disajipeared  at  the  ninth  month. 
The  red  blood-corpuscles  are  more  easily  decomposed  than  the  mother's,  but 
show  increased  resistance  to  hemolysis  by  cobra  toxin.  Boys  have  more  thaii  girls 
(8  per  cent.).  The  fetus  has  a  relative  leukocythemia,  and  the  number  of  leukocN-tes 
in  the  umbilical  vein  is  greater  than  in  the  arteries;  wherefore,  since  the  white  blood- 
corpuscles  cannot  pass  over  from  the  mother,  one  must  conclude  that  they  are 
made  in  the  placenta. 

The  hemorrhagic  and  icteric  tendencies  of  the  new-born  and  its  weakness 
against  infection  show  that  it  has  a  special  blood  pathology,  but  little  is  actually 
known  about  it.  Its  immunities  are  not  yet  developed,  and,  unless  it  receives  anti- 
bodies from  the  mother  via  the  milk,  it  succumbs  easily  to  infections. 

The  Fetal  Circulation.— The  uml)ilical  vesicle  has  imtritive  ])roperties;  it  ac- 
quires a  store  of  nutriment  from  the  mother,  and  supplies  it  to  the  growing  embryo 
through  two  sets  of  vessels — the  om]ihalomesenteric  arteries  and  veins.  This  is  the 
first,  or  "vitelline,"  circulation;  it  is  ])r()minent  for  the  first  twelve  days,  and  dis- 
appears about  the  fifth  we(>k  (Fig.  SI).  With  the  develoiiment  of  the  chorionic  villi 
and  the  vessels  from  the  allantois  the  fetus  is  provitled  with  a  ninv,  ratlier  a  more 
direct,  source  of  nourishment.  The  capillary  system  of  the  allantoic  arteries  and 
veins  rapidly  invades  the  growing  villi,  and  thus  the  osmotic  connection  l)etween  th(> 
maternal  and  fetal  blood  is  soon  established.  Fig.  88  shows  the  vitelline  and  allan- 
toic circulation  existing  side  in-  side.  The  fetal  blood  now  ])a.sses  from  the  iirimitive 
heart  through  the  primitive  aorta,  the  allantoic  arteries,  to  the  caiiillaries  lining  the 
periphery  of  the  ovum,  and  dipping  into  the  chorionic  villi,  returning  through  the 

61 


62 


PHYSIOLOGY    OF    PREGNANCY 


allantoic  veins  to  the  heart  through  the  ducts  of  Cuvier.  As  the  liver  develops  the 
blood  returning  from  the  chorionic  area  through  the  allantoic  veins,  now  the  um- 
bihcal  vein,  traverses  the  liver,  but  soon,  since  the  vessels  of  the  liver  cannot  accom- 
modate the  rapidly  growing  demands  of  the  developing  placental  circulation,  a  by- 
pass is  formed  from  the  umbilical  vein  under  the  liver  to  the  inferior  vena  cava. 
Thus  the  returning  blood  from  the  now  fully  differentiated  placenta  passes,  part 
through  the  liver  with  that  from  the  portal  vein,  and  part  through  the  by-pass,  the 
ductus  venosus  Arantii,  into  the  inferior  vena  cava.     The  circulation  of  the  blood

in  the  fetus  before  birth  is  different  from  that  afterward,  and  at  no  part  of  the  body 
is  purely  arterial  blood  supplied.  This  is  easily  seen  in  children  delivered  by 
cesarean  section;  they  present  a  dull  blue  color,  almost  cyanotic. 

The  blood,  oxygenated  and  cleansed  in  the  placenta,  provided  -wdth  nutritive 
substances  and  water  for  the  fetus,  is  collected  by  the  branches  of  the  uml)ilical 
vein  and  passes  through  the  single  vein  of  large  caliber  to  the  child,  entering  its 
body  at  the  navel,  then  ascending  behind  the  parietal  peritoneum  to  the  liver.  Here 
the  vein  divides,  several  branches  entering  the  liver  directly,  others  anastomosing 


THE    PHYSIOLOGY    OF   THE    FETUS 


C3 


with  the  portal  vein,  while  one  larse  brancli  goes  directly  into  the  vena  cava.  This 
is  the  ductus  venosus  Arantii.  The  blood  oi"  the  vena  cava  ascendens  is,  of  course, 
venous,  and  mingles  with  that  coming  from  the  ductus  venosus,  both  proceeding  to 
the  heart,  which  is  entered  through  the  right  auricle.  Owing  to  a  peculiar  arrange- 
ment of  the  endocardium  a  valve-like  fold  is  thrown  up  near  th(>  oj)eiiing  of  the  cava, 
— the  Eustachian  valve, — which  directs  the  blood-stream  toward  the  septum  of  the 
auricles,  where  an  opening  exists — the  foramen  ovale.  This  comnmnication  be- 
tween the  auricles  permits  the  blood  from  the  ascending  cava,  during  cardiac  diastole, 
to  pass  directly  into  the  left  ventricle.  The  right  auricle  is  filled  by  venous  })loo{l 
coming  down  from  the  superior  vena  cava,  and  a  little  aflmixture  of  arterial  blood 
not  deflected  by  the  valvula  Eustachii.  This  dark  blood  flows  into  the  right  ven- 
tricle (Fig.  84).  When  the  cardiac  systole  occurs  (Fig.  85),  the  blood  (almo.st  ar- 
terial) in  the  left  ventricle  is  forced  into  the  aorta,  its  cranial  branches,  and  do\\Ti  into 
the  trunk.  The  venous  blood  in  the  right  ventricle  passes  up  through  the  ])vil- 
monary  trunk,  which  cUvides  into  three  branches — one  to  each  lung,  and  one  hirge 
division  which  anastomoses  with  the  aorta.     This  Ijy-pass  is  calletl  the  ductus

Botalli,  and  serves  to  relieve  the  functionless  lungs  of  the  excess  of  l)loo(l  that  the 
right  ventricle  throws  out.  One-half  of  the  l)lood  takes  this  short  cut  to  the  aorta. 
The  blood  in  the  arch  of  the  aorta,  tlierefore,  is  ciuite  arterial,  while  that  which  goes 
to  the  trunk  and  extremities  is  mostly  venous.  The  hypogastric — the  former  allan- 
toic— arteries,  leaving  the  external  iliacs  in  the  pelvis,  ascend  alongside  the  bladder 
and  urachus  to  the  navel,  then,  winding  s])irally  around  the  umbilical  vein  in  the 
cord,  reach  the  ])lacenta.  Here  they  split  up  into  arterioles  and  caiiillarics  in  tiie 
viUi.  The  fetal  blood  contained  in  the  placenta  is  constantly  undergoing  the 
changes  that  in  the  adult  occur  in  the  lungs,  the  liver,  the  blood-making  and  other 
organs  of  the  body.  The  jieculiar  distribution  of  the  fresh  blood  in  the  fetus  ac- 
counts for  the  variation  in  the  growth  of  its  organs.  The  liver,  receiving  the  ])lood 
coming  directly  from  the  placenta,  grows  ma.ssively,  and  is  thus  al)le  to  perform  its 
most  important  functions  in  fetal  life.  The  head  receives  the  l)lood  next  in  fn^sh- 
ness,  while  the  trunk  and  extremities  receive  the  poorest  Vilood.  Late  in  pregnancy 
the  opening  of  the  vena  cava  inferior  moves  over  to  the  right  of  the  auricle,  and  the 
foramen  ovale  begins  to  diminish  in  caliber:  thus  the  right  auricle  receives  fre.sh 
blood,  and  more  blood  is  forced  into  the  lungs  and  through  the  ductus  Botalli  into

the  lower  portion  of  the  body.     A  more  equable  distribution  of  nourishment 
effected,  and  greater  symmetry  of  the  body  results. 

After  the  birth  of  the  child  important  changes  in  the  blood-currents  occur. 
With  the  first  inspiration  the  lungs  expand.  The  pulmonary  vessels  are  dilated, 
and  blood  rushes  into  them  from  the  right  ventricle.  Since  the  lungs  now  take  all  the 
supply  from  the  pulmonary  artery,  the  by-pass  to  the  aorta,  the  ductus  arteriosus 
Botalli,  collapses  and  shrinks  up.  It  is  solidly  obliterated  in  a  few  weeks.  The 
aspiration  of  the  right  auricle  and  ventricle  draws  the  blood  from  the  umbilical  vein. 


Fig.  83. — Synchronous  Vitelline  and  Allantoic  Circulations  (schematic). 


This  and  the  influence  of  cokl  air  cause  the  vein  to  collapse.  Tying  the  cord  shuts 
off  permanently  the  supply  of  blood  from  the  vein.  It  collapses,  its  walls  aggluti- 
nate, and  in  a  few  weeks  the  vein  is  ol)literated,  remaining  as  a  cord-like  ligament 
for  the  liver — the  ligamentum  teres.  The  ductus  venosus  Arantii  also  collapses  and 
disappears.  The  pressure  in  the  right  auricle  ceasing,  that  of  the  left  auricle  and 
ventricle  increases,  which  results  in  the  gradual  closure  of  the  foramen  ovale.  This 
opening  sometimes  persists  for  months,  or  may  be  the  cause  of  permanent  and  fatal 
heart  disease.  Children  with  persistent  patent  foramen  ovale  are  cyanotic,  es- 
pecially when  crying  or  on  exertion,  and  are  called  "blue  babies" — morbus  cseru-

leus  The  h^TDOgastric  arteries  contract  and  thrombose.  This  is  due  to  the  fact 
that  the  left  Ventricle,  unassisted  as  formerly  by  the  right  ventricle  via  the  ductus 
Botalli,  cannot  force  the  blood  the  long  distance  through  the  cord  to  the  placenta. 
In  addition,  exposure  to  cold  contracts  the  umbilical  arteries.     The  pulsation  m  the

any  of  the  temporary  fetal  vessels  except  the  hypogastric  arteries.  .      .  ,     . 

Special  Physiology.— The  fetus  in  utero  has  all  the  functions  of  the  mtant, 
respiration,  digestion,  assimilation,  metabolism,  heat-production  and  regulation, 
excretion,  etc.,  but,  owing  to  its  particular  environment,  these  are  all  much  modihed. 
The  placenta  does  several  of  the  vital  functions  of  the  fetus  almost  entirely.     It  is 


THE    PHYSIOLOGY    OF   THE    FETUS  67 

the  lungs  of  the  child;  it  porforms  nearly  all  its  digestion;  it  assimilates  food;  it 
stores  up  glycogen  (Bernard),  and  it  is  the  general  excretory  organ.  (The  decidua 
seems  to  possess  the  glycogenic  power— Zaretzsky.)  Its  functions  should  be  c(jn- 
sidered  a  little  more  in  detail,  though  we  will  have  to  present  nmch  that  is,  at  this 
time,  unfinished,  or  only  partly  proved. 

Respiration. — Zweifel  proved  that  the  umbilical  vein  contains  oxygenated 
blood,  and  the  arteries  venous  blood.  If  the  placenta  becomes  detached  or  the 
cord  compressed,  the  child  dies  from  asphyxia.  These  two  facts  prove  that  the 
fetal  blood  is  su]:)plied  with  oxygen  in  the  placenta.  The  fetus  needs  little  oxygen, 
as  its  combustion  processes  are  slow;  it  moves  little  and  meets  with  no  resistance; 
it  has  no  perspiration  with  evaporation  from  the  skin.  It  loses  no  heat.  Since  this 
is  so,  the  fetus  tolerates  withdrawal  of  its  oxygen  supply- — asphj-xia — very  well  for 
a  time.  As  pregnancy  goes  on  this  toleration  is  lost.  It  is  believed  that  the  fetal 
blood  is  more  and  more  venous  in  the  later  months  of  ])regnancy.  The  process  by 
which  the  fetal  blood,  carried  to  the  placenta,  l)ecomes  oxygenated  is  probably 
analogous  to  the  process  going  on  in  the  lungs.  It  is  not  by  osmosis,  because  the 
oxygen  is  bound  to  the  hemoglobin.  The  vital  oxidizing  power  of  the  placental 
cells,  perhaps  through  the  medium  of  a  ferment,  si)lits  off  the  oxygen  antl  carries  it 
to  the  fetal  red  blood-corpuscles.  The  process  is  similar  to  internal  or  tissue  respira- 
tion, and  perhaps  the  fat  in  the  villi  facilitates  the  change  (Hofbauer). 

Digestion. — In  many  respects  the  villi  of  the  placenta  resemble  the  intestinal 
villi.  In  selective  and  vital  action  they  exceed  the  latter  in  vigor  and  variety  of 
function.  The  placenta  is  a  large  gland,  and  it  proljably  assumes  the  functions 
which  the  adult  glands  later  perform.  The  fetus  needs  albumin,  fat,  carbohydrates, 
water,  and  salts.  Exactly  how  albumin  is  carried  over  from  the  mother's  to  the 
fetus'  blood  is  not  known.  Albumose,  but  not  peptone,  is  found  in  the  placenta. 
Xory  i^rol^ably  the  syncytial  cells  secrete  an  albumin-sjilitting  ferment,  the  proteid 
going  over  into  a  compound  of  lower  t>T3e,  and  the  all)umin  is  then  reformed  inside 
the  fetal  vessels.  Fat,  according  to  Hofbauer,  is  found  in  the  deeper  parts  of  the 
syncytium  and  in  the  vacuolated  cells  in  the  form  of  fine  droplets.  It  comes  from 
the  blood  of  the  mother,  and  in  small  amounts  from  the  glands  of  the  uterus.  In 
cows  and  dogs,  for  example,  the  connection  of  the  villi  with  the  glands  is  intimate, 
and  the  latter  play  an  important  part  in  fetal  nutrition.  Physiologists  are  not  sure 
how  fat  exists  in  the  bloocl,  nor  do  they  know  how  it  passes  over  to  the  fetus.  Emul- 
sified fat  does  not  pass  the  placenta.  Probably  again  here  a  fat-splitting  ferment 
(lipase)  is  in  action,  fatty  acids  and  glycerin  being  formed.  The  analogy  between 
intestinal  and  placental  villi  is  again  strengthened. 

Water  is  readily  absorbed  by  the  villi,  differences  in  the  molecular  concentra- 
tion between  the  two  bloods  accomplishing  the  transfer.  Of  the  metals,  iron  is  one 
of  the  most  important,  and  the  fetus  needs  a  great  deal  of  it.  There  is  no  iron  in  the 
l)lood  plasma  of  the  mother,  therefore  the  red  corpuscles  must  be  used  l)y  the  tro]-)ho- 
blast  to  provide  the  necessary  amount.  Probably  the  syncytium  has  a  cytotoxic  or 
hemolytic  action  on  the  erythrocj'tes,  perhaps  dependent  on  the  transformation  of 
the  lipoid  substances  in  the  covering  of  the  cells  (Overton).  The  red  blood-cor- 
l^uscles  are  destroyed  ])y  the  villi,  and  the  hemoglo])in,  by  complicated  and  not  fully 
understood  biochemical  processes,  is  unmade  and  reformed  in  the  fetal  red  i)looil- 
corpuscles.  Perhaps  this  destruction  of  erythrocytes  accounts  for  some  of  the 
anemia  of  women  in  the  early  months  of  pregnancy.  Mayer,  in  1827,  proved  that 
substances  in  solution  in  the  maternal  blood  pass  on  to  the  fetus  through  the  mem- 
l)rane  separating  fetal  and  maternal  blood,  e.  g.,  salts,  potassium  iodid,  salicylic 
acid,  atropin,  etc.,  and  in  amount  as  they  are  dialyzable.  Ciases  pass  over,  as 
chloroform  and  carbon  choxid;  therefore  the  danger  of  giving  too  much  chloroform. 
Ahlfeld  found  the  liquor  amnii  in  many  cases  of  cesarean  section  stained  with  me- 
conium.    Nicloux  assembled  our  knowledge  on  this  subject  up  to  1909.     Pregnant 


68  PHYSIOLOGY    OF    PREGNANCY 

women  should  avoid  large  gatherings,  or  where  large  coal-stoves  are  used,  as  the 
carbon  monoxid  may  injure  the  fetus. 

The  placenta,  then,  prepares  the  food  for  the  infant,  so  that  it  may  be  immedi- 
ately used  for  its  general  metabolism.  In  addition,  the  intact  placenta  offers  a 
barrier  to  the  passage  of  infection  to  the  fetus.  Only  if  its  walls  are  injured  will  the 
villus  allow  bacteria  to  pass.  (See  Pathology  of  Pregnancy.)  If  bacteria  do  not 
pass,  many  toxins  do,  but  antitoxins,  e.  g.,  diphtheria  and  antitetanus  sermn,  do  not 
pass  over. 

As  another  source  of  nourishment,  mention  must  be  made  of  the  liquor  amnii. 
It  contains  a  slight  amount  of  albumin,  and  the  fetus  drinks  it  in  large  quantities. 
This  is  proved  by  finding  lanugo  in  the  meconium,  and  the  infant  vomiting  the  liquor 
amnii  after  birth.  The  stomach  of  the  fetus  contains  pepsin,  and  the  intestines  a 
trjqDtic  ferment;  therefore  the  function  of  digestion  could  be  carried  on.  AYater  is 
probably  supplied  the  fetus  in  this  manner.  Until  the  second  month  the  fetus  is 
almost  all  water,  has  less  solids  even  than  milk.  At  the  end  of  pregnancy  the  fetus 
is  74  per  cent,  water.  The  liver  is  active,  demonstrated  by  its  preponderating  bulk 
and  the  presence  of  bile  in  the  meconium.  The  meconium  is  a  tarry,  greenish- 
black  substance,  found  in  the  colon  of  the  fetus  in  considerable  quantity  even  before 
the  seventh  month.  It  accumulates  in  the  colon  and,  therefore,  peristalsis  must 
occur  in  the  intestines.  This  has  also  been  demonstrated  experimentalh'.  The 
meconium  becomes  tliicker  in  the  latter  weeks,  since  the  intestine  is  absorptive. 
It  is  composed  of  secretions  of  the  intestinal  canal,  the  solid  particles  swallowed 
with  the  liquor  amnii;  lanugo,  epithelium,  vernix  caseosa,  and  bile,  and,  chemically, 
cholesterin,  bilirubin,  fat,  and  mucin. 

The  Kidneys. — These  are  active  from  the  early  months,  as  Nagel  has  sho^^^l. 
Ahlfeld  denies  that  the  liquor  amnii  contains  urine.  He  says  the  excrementitious 
matters  which  the  kidney  usually  excretes  are  taken  away  through  the  placenta. 
Still,  urea  has  been  found  in  the  liquor  amnii ;  the  bladder  has  been  found  distended, 
even  so  as  to  be  a  hindrance  to  labor;  the  kidneys  are  there,  and,  by  analogj^  with 
other  organs,  must  work.  Urine  is  often  found  in  the  bladder  of  new-born  children. 
They  sometimes  urinate  freely  during  delivery.  Probably  the  action  of  the  kidneys 
before  birth  is  not  constant  nor  considerable — rather,  exceptional.  Ahlf eld's 
arguments  are  very  plausible.  The  child  has  its  own  general  metabolism — internal 
respiration,  anabolism,  catabolism,  heat-production  all  go  on  as  in  the  adult,  but  in 
varjdng  degrees.  The  tissue  changes  are  very  active,  since  growth  is  so  rapid,  but 
the  child  needs  to  produce  very  little  heat,  being  so  well  protected.  Its  temperature 
is  one-half  to  three-fourths  of  a  degree  higher  than  that  of  the  mother.  The  prod- 
ucts of  the  fetal  metabolism  are  carried  to  the  placenta.  Glands  with  internal  se- 
cretion probably  functionate. 

Less  is  known  of  the  excretory  functions  of  the  placenta,  but  such  a  function 
surely  exists,  since  the  fetus  has  very  little  other  outlet  for  its  waste  matters.  Some 
waste  may  accumulate  as  meconium  in  the  intestinal  canal,  and  a  little  more  may  be 
passed  as  urine  or  perspiration.  That  the  mother  can  absorb  materials  from  the 
child  is  proved  by  the  injection  of  a  salt,  as  iodid  of  potassium,  into  the  child,  and 
its  demonstration  in  the  saliva  of  the  mother.  That  substances  will  pass  from  fetus 
to  mother  was  known  to  Harvey.  Carbon  dioxid  passes  from  the  fetus  and  is  ex- 
creted by  the  mother. 

The  amount  of  actual  waste  furjiished  by  the  child  cannot  be  large,  because  its 
nourishment  is  provided  in  a  condition  ready  for  immediate  assimilation  and  con- 
version into  living  protoplasm. 

The  Determination  of  Sex. — It  is  felt  that  there  must  be  a  natural  law  govern- 
ing the  ]:)roduction  of  males  and  females,  because  the  proportion  between  the  two  in 
nearly  all  countries  is  as  105  or  106  is  to  100.  The  males  have  a  higher  death-rate 
in  delivery  and  after,  so  that  among  adults  the  relation  is  reversed.     What  this  law 


THE  PHYSIOLOGY  OF  THE  FETUS  69 

is  no  one  knows,  but  we  have  many  theories,  a  review  of  which  may  be  found  in  the 
hterature  indicated  below  (Cohn,  Dawson,  Morgan,  Rauber). 

Sex  may  be  determined^ — (1)  In  the  ovum  itself;  (2)  at  the  time  of  fertilization 
by  the  spermatozoid;  (3)  by  the  infiuenee  of  external  factors  during  the  first  forma- 
tive period  of  the  embrj^o.  All  the  theories  proposed  may  be  grouped  under  these 
headings. 

That  the  oxiim  itself  carries  the  sex-individuality  is  shown — (a)  By  the  constant 
occurrence  of  one  sex  in  unioval  twins;  (6)  the  embryologic  demonstration  of  sex 
differences  in  even  the  earliest  human  ova;  (c)  the  preponderance  of  monstrosities 
in  the  female  sex;  (d)  in  certain  worms  {Dinophilus  apairis)  one  can  distinguish 
male  and  female  ova;  (e)  the  phenomena  of  parthenogenesis  in  certain  inverte- 
brates. There  is  no  scientific  basis  for  the  supposition  that  the  spermatozoid  has 
any  influence  on  the  S8X  of  the  fetus,  though  recently  Wilson  and  Stevens  have 
sought  to  prove  that  in  certain  insects  the  chromosomes  present  different  arrange- 
ments in  the  spermatocytes,  and  the  resulting  spermatozoids,  therefore,  have  vary- 
ing fertilizing  power  on  the  ovum.  Regarding  the  influence  of  environment,  scien- 
tists differ.  Floss  and  Waldeyer  claimed  that  in  the  lower  forms  of  life,  as  melons, 
cucumbers,  favorable  conditions  produce  females,  and  Fiirst  claims  that  the  larvae 
of  bees,  when  the  nourishment  is  insufficient,  result  in  hermaphrodites.  On  the 
other  hand,  Pfliiger,  Schultze,  and  Heapes  (quoted  by  Ahlfeld,  Igc.  cit.)  have  been 
unable  to  modify  the  sex  of  frogs,  mice,  and  rabbits  by  altering  their  environment. 

]\Iany  conditions  have  ])een  assumed  as  causative  of  sex  distinction,  and  at- 
tempts have  been  made  to  influence  nature,  based  on  these,  usually  false,  assump- 
tions. Hippocrates  and  Galen  believed  that  boys  came  from  the  right  ovary,  girls 
from  the  left,  and  Henke,  in  178G,  advised  coition  on  the  corresponding  side  when 
a  child  of  that  sex  was  desired.  Hofacker  and  Sadler  believed  that  the  father,  if 
older,  would  produce  more  males.  Other  statistics  prove  the  reverse.  It  is  a  fact 
that  old  primiparse  have  a  preponderance  of  boys.  Women  with  contracted  pelves 
have  more  boys,  perhaps  because  they  are  usually  older  when  they  marry. 

Impregnation  of  an  ovum  Ijefore  menstruation  is  said  to  produce  females;  after- 
ward, males  (Thury).     It  may  be  true  of  animals,  but  is  not  in  the  human. 

Janke  claimed  the  w^eaker  party  in  the  sexual  act  produced  the  opposite  sex, 
and  advised  that  either  the  man  or  the  woman  be  at  the  height  of  sexual  potency, 
depending  on  the  sex  desired.  Diising,  from  the  study  of  10,500,000  births,  finds 
more  boys  are  conceived  in  Avinter  than  in  summer,  and  Floss  found  that  women  in 
high  altitudes  give  birth  to  more  sons  than  those  on  the  plains. 

Schenk  believed  that  the  sex  of  the  offspring  depended  on  the  nutrition  of  the 
mother;  if  her  metabolism  is  so  affected  by  conditions  during  pregnancy  that  sugar 
appears  in  the  urine,  the  product  of  conception  will  be  female;  if  the  patient  is  kept 
on  a  diet  that  will  prevent  sugar,  or  reduce  the  carbohydrates  in  the  urine,  the  child 
will  be  a  boy.     Experience  has  proved  the  utter  fallacy  of  this  theory. 

Nature  still  holds  the  secret  of  sex  production,  and  it  is  not  desirable,  even  if 
it  were  possible,  for  man  to  interfere  in  the  matter.

CHAPTER  IV 
CHANGES  DUE  TO  PREGNANCY 

LOCAL  CHANGES 

The  rapidly  growing  ovum  makes  many  demands  on  the  maternal  organism. 
It  requires  a  great  deal  of  room  for  its  development,  and  a  free  blood-supply  for 
its  nourishment;  then,  too,  the  parturient  canal  must  be  prepared,  and  the  means 
pro\nded  for  the  expulsion  of  the  completed  child.  These  are  the  local  requirements : 
there  are,  in  addition,  demands  on  the  organs  of  general  metabolism — the  liver, 
the  kidnej's,  the  ductless  glands,  the  nervous  system,  etc.,  and,  unless  the  proper 
balance  is  maintained,  either  mother  or  child  or  both  will  suffer.  To  meet  these 
requirements  of  the  gTowing  fetus  the  whole  body  of  the  mother  undergoes  certain 
changes,  which  for  the  purpose  of  study  are  divided  into  local  and  general.

Local  Changes. — Xaturall,y  the  uterus  is  most  markedly'  altered.  The  normal 
uterus  of  a  nulligravida  is  a  pear-shaped  organ,  63/2  cm.  long,  2}/2  cm.  thick,  and 
4  cm.  wide,  weighing  42  gm.  In  multiparse  the  uterus  is  l}/2  cm.  long,  5  cm.  wide, 
and  3  cm.  thick,  weighing  65  gm.  It  is  made  up  of  hard,  unstriped  muscle,  covered 
in  part  by  the  peritoneum,  moored  to  the  pelvis  by  eight  so-called  ligaments,  and 
attached  to  the  pelvic  floor  by  means  of  the  vagina. 

During  the  first  half  of  pregnancy  the  uterus  enlarges  as  the  result  of  a  hyper- 
plasia of  its  muscular  substance.     This  is  a  true  eccentric  growi:h,  is  much  more

rapid  than  is  sufficient  to  accommodate  the  growing  ovum,  and  is  not  due  to  expan- 
sion by  the  growing  ovum,  as  the  same  changes  occur  in  the  uterus  even  when  the 
ovum  develops  outside  of  it.  There  are  hypertrophy  and  also  hyperplasia  of  the 
cells.  The  wall  of  the  uterus,  which  was  8  mm.  before  pregnancy,  grows  to  be  25 
mm.  thick  by  the  fourth  month.  After  this  the  decidua  reflexa  comes  to  lie  on  and 
fuse  with  the  decidua  vera,  and  the  development  of  the  uterus  is  coetiual  with  that 
of  the  ovum.     At  no  time  in  pregnancy  does  the  ovum  actively  distend  the  uterus.

Removed  at  time  of  a  cesarean  section. 

In  cases  of  twins  and  polyhydramnion  there  may  be  pathologic  distention  of  the 
uterus.  At  the  end  of  pregnancy  the  uterine  wall  varies  from  4  to  7  mm.  in  thick- 
ness, and  it  is  remarkable  what  muscular  power  this  thin-walled  organ  may  develop. 
The  muscle-filier  of  the  non-pregnant  uterus  is  spindle  shaped,  and  about  50^ 
long.  That  of  the  full-term  pregnant  uterus  is  enormously  enlarged  (200  to  600 /x) 
and  presents  fine  longitudinal  fibrillations  (Figs.  84,  86.  and  87).  The  muscle-fibers 
of  the  cervix  also  undergo  hypertrophy,  but  not  as  much  as  those  of  the  fundus. 


72 


PHYSIOLOGY    OF    PREGNANCY 


Rarely  cross-striated  muscle-fibers  have  been  found  in  the  uterus,  a  phenomenon 
that  may  indicate  metaplasia. 

The  fibro-elastic  tissue  of  the  uterus  is  of  great  importance  in  view  of  the 
functions  of  the  organ  and  its  resistance  to  distention  and  the  stress  of  lal)or. 
Dlihrssen  and  others  have  sho^^^l  that  the  fundus  is  less  rich  in  elastic  tissue  than 
the  cervix,  that  the  fibers  are  most  numerous  in  the  outer  laj'ers  of  the  uterus  and 
around  the  vessels,  from  which  they  probal^ly  arise.     Fieux  states  that  the  muscula-

ture  of  the  cervix  has  disappeared  before  term,  to  be  regenerated  after  labor,  so 
that  at  the  end  of  pregnancy  the  cervix  is  composed  entirely  of  connective  tissue. 
No  one  has  confirmed  this  view. 

The  uterine  connective  tissue  becomes  augmented,  softer,  and  slightly  fibril- 
lated,  permitting  free  motion  between  the  muscle-bundles  and  layers.  How  much 
hyperplasia  exists  is  under  question. 

The  arrangement  of  the  muscle-fibers  has  been  the  object  of  an  immense  amount

of  study,  and  it  is  not  yet  fully  understood.  Bayer  gives  a  full  history  of  the 
subject,  and  his  description,  with  those  of  Helie  and  Chenantais,  will  be  followed. 
In  general  three  layers  may  be  distinguished :  an  outer  thin,  an  inner,  also  thin,  and 
the  middle,  very  thick  and  vascular.  These  layers  are  distinguishable  only  during 
pregnancy.  At  cesarean  sections  one  observes  them,  and  it  is  possible  to  unite 
them  individually  by  suture.  Since  the  uterus  is  the  result  of  the  fusion  of  the  two 
Miillerian  ducts,  we  would  expect  the  tubes  to  play  a  role  in  the  distribution  of  the 


CHANGES  DUE  TO  PREGNANCY  73 

uterine  muscular  fibers,  iiiid  tiiis  is  borne  out  by  various  tlissections.     The  uterine 
ligaments  also  determine  the  direction  of  the  muscular  bundles  (Ivanoff). 

The  outer  layer  of  the  uterus  covers  the  fundus  down  to  the  jioint  where  the 


Fig.  90. — Dissection  of  Uterine  Muscle.     Fundus  (from  Helie  and  Chenantais). 

peritoneum  is  loosely  attached,  and  is  composed  of  the  longitudinal  fibers  of  the 
tubes  (Fig.  88).  It  is  hood-like,  but  does  not  cover  the  sides  of  the  uterus,  where 
the  blood-vessels  enter.  The  fibers  are  more  or  less  longitudinal,  and  interlace  in 
the  middle,  some  crossing  to  the  opposite  side.     The  inner  layer  of  the  longitudinal

fibers  of  the  tube  is  continued  under  the  endometrium,  and  forms  the  looped  bundles 
of  muscle  around  the  tubal  ostia  and  around  the  internal  os.  The  powerful  middle 
layer  is  composed  of  the  circular  fibers  of  the  tube  and  the  radiating  fillers  from  the 
sacro-uterine  ligaments,  the  round  and   the  ovarian  ligaments  (Fig.  89).     These 


74 


PHYSIOLOGY    OF   PREGNANCY 


ligaments,  during  the  development  of  the  uterus  in  pregnancy,  exert  a  marked 
effect  on  the  direction  of  its  growth,  and  during  labor  have  a  decided  influence  in 
the  mechanism  of  the  process. 

As  a  result  of  the  crossing  and  recrossing  of  the  various  muscular  lamellae 
and  bundles,  a  most  complicated  network  results,  and  through  this  network  the 
blood-vessels  of  the  uterus  pursue  their  course.  It  is  easily  seen  that  when  the 
muscle  contracts,  these  vessels  will  be  twisted,  bent,  and  closed.  This  is  what 
normally  occurs  in  the  third  stage  of  labor  after  the  child  is  expelled.  The  lamellar 
structure  of  the  uterus  is  necessary  to  permit  the  distention  of  the  uterus  and  its 
accommodation  to  the  growing  ovum. 

The  muscle-fibers  of  the  cervix  pursue  simpler  courses.  At  the  isthmus  the 
circular  laj^ers  are  prominent,  especially  at  the  insertion  of  the  retractor  fibers  in 
the  rear,  i.  e.,  the  uterosacral  ligaments.     The  plicae  palmatae  are  made  up  of  longi- 


FiG.  92. — Middle  Layer  of  Uterine  Fibers  (from  Helie  and  Chenantais). 


tudinal  fibers.  Externally  the  cervix  shows  a  layer  of  longitudinal  and  oblique 
fibers  which  spread  out  into  the  bladder  through  the  vesico-uterine  ligaments 
and  into  the  bases  of  the  broad  ligaments.  The  portio  vaginalis  presents  an  inner, 
submucous,  circular  layer,  derived  from  the  vagina,  an  outer,  longitudinal,  from  the 
same,  and  a  middle  layer,  vascular  and  not  pronounced,  from  the  similar  layer  of 
the  fundus  compounded  with  the  ligaments  entering  the  cervix.  Reynolds,  in 
1911,  showed  the  clinical  importance  of  these  ligaments. 

The  blood-supply  of  the  uterus  must  be  very  liberal  to  render  possible  the 
immense  changes  in  the  organ.  The  vessels  undergo  hypertrophy  and  probably 
hyperplasia  also.  The  arterial  supply  of  the  uterus  is  derived  mainly  from  the 
uterine,  a  branch  of  the  hypogastric,  the  ovarian  or  spermatic,  a  branch  of  the 
aorta,  and  the  funicular,  a  branch  of  the  vesical,  which  passes  up  the  round  liga- 
ment and  joins  the  ovarian  at  the  fundus  uteri.  The  uterine  artery,  arriving  at 
the  side  of  the  uterus  at  the  level  of  the  cervix,  gives  off  a  large  branch  which  goes 


CHANGES  DUE  TO  PREGNANCY 


75 


down  on  the  vagina  (artoria  oervicovaginalis),  the  main  trunk  aseending  in  the 
broad  ligament  closely  at  the  side  of  the  uterus.  At  the  level  of  the  internal  os 
it  begins  to  give  off  branches  which  cross  through  the  substance  of  the  uterus,  to 
anastomose  with  those  of  the  other  side.  The  trunk,  Avhich  is  sometimes  called  the 
pueqx'ral  artery,  rises,  giving  off  branches  all  the  way,  and  unites  with  the  sper- 
matic or  ovarian  artery.  These  vessels  are  wonderfully  twisted,  even  to  the 
smallest  branches,  and  their  anastomoses  are  frequent  and  full  (Fig.  93).  (See 
also  Kedlich  in  literature.) 

The  veins  are  much  more  developed  than  the  arteries,  and  in  general  follow 
their  course.  They  penetrate  all  the  layers  of  the  uterus,  especially  the  middle, 
anastomose  very  freely,  and  empty  into  the  plexuses  at  the  sides  of  the  uterus  in  the

ovarian  and  broad  ligaments.  The  former  empties  into  the  renal  vein  or  the  cava, 
the  latter  into  the  hypogastric  vein,  and  thence  into  the  internal  iliac.  The  uterine 
veins  have  no  valves. 

Microscopically,  both  arteries  and  veins,  particularly  the  veins,  undergo 
interesting  changes  in  the  uterine  wall.  They  lose  their  outer  coats,  and  come  to 
lie  on  the  muscle-bundles,  with  only  an  intima  or  with  very  little  tunica  media, 
really  forming  large  blood-spaces  called  sinuses.  The  uterus  th\is  seems  to  form 
part  of  the  vascular  system,  and,  as  a  matter  of  fact,  it  follows  vasomotor  impulses, 
for  instance,  the  action  of  ergot  and  adrenalin  and  of  nervous  shocks. 

The  lymphatics  of  the  uterus  enlarge  and  multiply  during  pregnancy,  so  that 
the  full-term  organ  is  well  honeycombed  by  them.     They  begin  as  large  spaces

under  the  endometrium  and  under  the  serosa,  following  the  course  of  the  muscle- 
bundles  and  blood-vessels;  they  anastomose  freely  under  the  serosa,  communicat- 
ing by  stomata  with  the  ]5eritoneal  cavity,  and  empty  into  the  vessels  of  the  broad 
ligament.  The  lymphatics  of  the  corpus  uteri  empty  into  the  lumbar  glands; 
those  of  the  cervix  into  the  pelvic  glands;  those  which  accompany  the  round  liga- 
ment into  the  upper  set  of  deep  inguinal  glands;  those  of  the  lower  vagina  and 
vulva  go  to  the  deep  and  superficial  inguinal  glands,  and  through  these  to  the 
glands  around  the  external  iliac  arteries.     The  large  size  and  great  number  of  the

lymphatics  in  and  around  the  uterus  must  be  noted,  also  the  distribution  of  the 
various  streams  of  lymph,  as  this  is  important  in  the  consideration  of  puerperal 
fever. 

The  nervous  supply  of  the  uterus  is  very  rich,  and  comes  from  both  sympa- 
thetic and  (•(  rcbrospinal  systems.  ^Nlotor  fibers  are  derived  from  the  sympathetic, 
passing  down  from  the  aortic  plexus;  they  are  reinforced  by  fibers  from  the  solar, 
renal,  and  genital  ganglia,  forming  a  large  plexus  above  the  promontory  of  the  sacrum, 
near  the  bifurcation  of  the  aorta,  and  called  the  great  uterine  plexus.  From  here 
the  fibers  pass  on  either  side  of  the  rectum  through  the  hj^pogastric  plexuses  to  the

sides  of  the  uterus,  ])ut  mainly  to  the  great  eervical  ganghon  and  thus  into  the 
uterus.  Cerebrospinal  fibers  coming  from  the  pneumogastrie,  phrenic,  and  splanchnic 
nerves  follow  the  same  course.     Their  function  is  unknown.     The  close  nervous

connection  between  the  uterus  and  the  stomach  and  heart  may  explain  the  reflex 
phenomena  intercurrent  between  these  organs.  Sensory  fibers  come  from  the 
spinal  cord  through  the  sacral  nerves,  being  also  distributed  via  the  great  cervical

ganglion.  That  the  sensory  fibers  come  from  the  spinal  cord  in  this  way  is  sho-^Ti 
by  the  clinical  observation  of  painless  labors  in  paraplegic  women,  and  rendering 
the  labor  painless  by  the  injection  of  cocain  into  the  spinal  canal.  The  region 
supplied  by  the  cauda  is  made  anesthetic.  The  great  cervical  ganglion  (Franken- 
hauser)  is  a  triangular  mass  of  ganglion-cells  and  nerve-fibers  lying  at  the  side  of 
the  cervix  and  upper  vagina,  3^  inch  wide  and  %  inch  long.  During  pregnancy  it 
grows  to  be  2  inches  long  and  13^  inches  wide.  Another  ganglion  exists  on  the 
posterior  wall  of  the  cervix. 

The  nerve-centers  are  less  well  knoA\ni.  One  is  believed  to  exist  in  the  cortex, 
one  in  the  medulla,  in  the  cerebellum,  and  in  the  lumbar  enlargement  of  the  cord, 
because  irritation  at  these  points  causes  uterine  contractions.  There  is  an  indepen- 
dent nerve-center  in  the  uterus,  because  the  organ  acts  even  when  removed  from  the 
body.     Cases  of  paraplegia  are  on  record  where  labor  was  normal  or  even  pre-

cipitate.  The  author  delivered  a  paraplegic  with  forceps  after  the  head  was  visible 
because  of  failure  of  the  abdominal  muscles  to  contract.  This  local  center  is  sup- 
posed to  be  the  great  cervical  ganglion,  but  there  exist  ganglionic  cells  in  the  uterine 
muscle,  and  they  form  occasional  small  plexuses  around  the  blood-vessels  (Bar). 

Changes  in  the  Shape  of  the  Uterus. — Within  two  weeks  after  conception  the 
shape  of  tiie  uterus  begins  to  change.  This  is  first  appreciable  in  the  antero- 
posterior diameter  of  the  corpus.  The  ovum  softens  and  distends  that  part  of  the 
uterus  in  which  it  is  situated.  As  this  is  usually  the  anterior  wall,  we  find  a  bulging 
here  on  one  or  the  other  side  of  the  median  line,  making  the  affected  side  larger, 
thicker,  and  softer,  while  the  other  is  smaller,  thinner,  and  harder,  there  being  a 
groove  between.  These  findings  are  useful  in  the  diagnosis  of  pregnancy.  The 
cervix  softens,  especially  the  supravaginal  portion,  its  acquired  compressibility 
giving  Hegar's  sign  of  pregnancy.     The  junction  of  the  tubes  with  the  uterus  also 


CHANGES    DUE    TO    PREGNANCY 


79 


softens.  These  conditions  are  brought  al)out  especiaUy  by  imbibition  of  the  uterine 
wall  and  the  moval)ihty  of  tlie  outer  lamella  of  the  uterine  muscle  on  the  middle 
coat.  After  the  second  month  one  finds  the  uterus  enlarged  laterally,  and  in  the 
third  month  the  fundus  has  assumed  nearly  a  spheric  form.  The  consistence  of  the 
uterus  at  this  time  is  spong>%  elastic,  and  soft,  like  bread  dough,  and  one  often 
notices  the  organ  harden  under  the  examining  hand — that  is,  it  contracts. 

The  cervix  softens  and  enlarges  up  to  the  fourth  month,  when  it  rcsemljles  a 
large  nipple  hanging  from  the  globular  corpus.  Normally,  the  mucous  membrane 
of  the  cervix  is  not  altered  into  decidua,  and  it  produces  a  thick,  tenacious  mucus, 
which  fills  the  canal,  closing  the  uterine  cavity  from  the  vagina.  This  mucous 
plug  is  constantly'  renewed  from  above  and  prevents  ascending  infection.  After 
the  fifth  month  the  uterus  enlarges  in  the  direction  of  the  fundus,  the  spheric  form 


'^■Vtmi::;/

becoming  ovoid  or  elliptic.  The  location  of  the  tubal  insertion  and  of  the  round 
ligaments  shows  this  change,  at  the  fifth  month  being  near  the  vault  of  the  uterus, 
at  the  ninth  month  being  4  to  6  inches  lower.  During  the  last  weeks  of  pregnancy 
the  lower  part  of  the  uterus  is  developed  to  accommodate  one  pole  of  the  infant, 
the  so-called  lower  uterine  segment  being  formed.  This  completes  the  ovoid  or 
elliptic  formation  of  the  uterus  (Figs.  98,  99,  100,  101,  102). 

The  virgin  uterus  is  shaped  like  a  flattened  pear,  and  has  a  capacity  of  2  c.c. 
or  less;  the  full-term  uterus  resembles  an  immense  gourd,  and  has  a  capacity  of 
4000  to  5000  c.c. 

The  configuration  of  the  uterus  is  affected  by  the  organs  in  the  belly,  the  posi- 
tion and  attitude  of  the  fetus,  the  amount  of  liquor  amnii,  the  location  of  the  pla- 
centa, the  attitude  of  the  mother,  uterine  neoplasms,  adhesions,  etc.     The  spinal 


80 


PHYSIOLOGY    OF   PREGNANCY 


column  presses  into  the  uterus  from  Ijehind;  the  intestines  leave  facets  on  its  walls. 
Since  the  anterior  wall  is  supported  solely  by  the  abdominal  muscles,  it  bulges 
forward  convexly.  The  fetus  kicks  out  the  non-resistant  muscle,  as  may  be  observed 
during  any  abdominal  examination.  In  shoulder  presentation  the  uterine  ovoid 
is  transverse.  A  large  quantity  of  liquor  amnii  makes  the  uterus  spheric  and  tense. 
The  placenta  develops  that  part  of  the  uterus  to  which  it  is  attached,  and,  from  the 
location  and  course  of  the  round  ligaments,  we  make  deductions  as  to  the  seat  of 
the  placenta  (Palm).  If  the  round  ligaments  run  on  the  anterior  surface  of  the 
uterus,  the  placenta  is  located  on  the  posterior  wall;  if  they  are  far  to  the  side, 
the  placenta  is  located  anteriorly  (Figs.  102  and  103). 

We  find,  at  term,  uteri  of  various  shapes — ovoid  and  elliptic,  cordate  and 
asymmetric  (Figs.  104,  105,  106,  107,  108).  Occasionally  the  fundus  presents  a 
shallow  groove  (Fig.  106),  the  uterus  having  an  indication  of  horns — uterus  arcuatus. 


Fio.  99. — Uterus  near  Term. 
From  Professor  Jaggard's  collection.     Note  primary  brow  presentation. 


Sometimes  one  horn  is  developed  more  than  the  other  (Fig.  107).  The  uterus  at 
term,  in  80  per  cent,  of  cases,  is  deviated  to  the  right  side  of  the  abdomen,  and  it 
is  also  twisted  on  itself  from  left  to  right.  This  dextroversion  and  torsion,  which 
are  also  found  in  the  virgin  state,  are  due  to  the  mode  of  formation  of  the  uterus 
from  the  Miillerian  ducts — in  the  fetus  the  left  duct  lies  anterior  to  the  right; 
second,  the  location  of  the  mesenteric  attachment  of  the  sigmoid  on  the  left  side 
of  the  spinal  column;  third,  congenital  asymmetry  of  growth,  which  is  noticeable 
even  in  vegetable  life — for  instance,  trees  and  shrubs;  fourth,  the  full  rectum; 
fifth,  the  general  habit  of  lying  on  the  right  side — the  uterus  falling  over  from  the 
left.  This  dextroversion  of  the  uterus  is  of  considerable  clinical  importance.  In 
abdominal  examinations  the  left  tube  and  ovary  may  be  felt  nearer  the  middle  line, 
and  the  round  ligament  also  is  more  prominent  on  the  left  side.  During  the 
operation  of  cesarean  section  it  is  necessary  to  bring  the  uterus  to  the  middle  line 
before  making  the  incision  for  the  delivery  of  the  child.

is  readily  felt  through  the  anterior  fornix.     The  cervix  is  directed  forward  (Fig.  110). 
As  the  pregnancy  develops  the  uterus  rises  up  in  the  abdomen,  coming  to  lie  against 
its  anterior  wall.     In  primiparce  the  uterus  is  molded  against  the  spinal  column  more

than  in  multiparse,  because  in  the  latter  the  al^dominal  muscles  are  usually  not  so 
strong  and  rigid.  The  intestines  are  forced  upward  and  usually  to  the  left.  No 
intestine  normally  is  found  between  the  uterus  and  the  abdominal  wall.  A  hernia 
is  sometimes  emptied  of  gut  during  pregnancy.     The  colon  retains  its  position.

The  fundus  uteri  at  term  is  about  the  level  of  the  second  lumbar  vertebra.  It 
exerts  no  direct  pressure  on  the  kidneys,  liver,  or  stomach,  and  is,  therefore,  not 
answerable  for  certain  troubles  of  these  organs  ascribed  to  it,  as  nephritis,  icterus, 
intercostal  neuralgia,  hyperemesis.  In  the  latter  three  months  the  lower  pole  of 
the  uterus  lies  on  the  ureters  as  they  cross  the  brim  of  the  pelvis.     Undoubtedly,

Fig.  107. — Asymmetric  Development. 


the  ureters  are  sometimes  occluded  by  the  growing  uterus,  but  it  is  not  by  its 
weight,  because  the  specific  gravity  of  the  organ  is  the  same  as  that  of  the  intestinal 
mass.  Proba])ly  the  ureters  are  bent  or  twisted  during  the  changing  of  the  rela- 
tions of  the  pelvic  viscera. 

The  bladder  during  early  pregnancy  is  a  pelvic  organ.     In  the  la^t  month, 


CHANGES   DUE   TO    PREGNANCY 


83 


pari  passu  with  the  development  of  the  lower  uterine  segment,  the  bladder  is  drawn 
up  from  ]:)(^hind  the  pubis  into  the  abdomen,  generally  to  the  right.  During  labor 
the  uterus  draws  away  from  the  bladder,  Ijut  the  latter,  wh(m  filled,  may  reach 
above  the  navel.  The  urethra  is  stretched  only  when  the  bladder  is  overfilled,  or 
during  labor  when  it  is  out  of  the  true  pelvis.  Often  the  bladder  is  saddle  shaped, 
extending  on  each  side  of  the  pelvis.  It  may  also  be  asymmetric,  with  the  larger 
part  on  the  right. 

The  axis  of  the  uterus  varies  in  its  relation  to  that  of  the  axis  of  the  pelvic 
inlet.  In  primipara?,  standing,  the  two  axes  sometimes  correspond  (Fig.  111).  In 
multiparae  the  lax  abdominal  wall  allows  the  uterus  to  fall  forward.  If  the  recti 
abdominis  are  widely  separated,  the  fundus  falls  between  them,  resulting  in  "pen- 
dulous abdomen,"  or  '^  rupture,"  as  the  women  term  it  (Fig.  113).     When  the  woman

OF  Fetus.

Shows  flexion  over  spinal  column. 


lies  in  the  horizontal  position,  the  uterine  axis  sinks  Ijehind  that  of  the  inlet  (Fig. 
112). 

Up  to  the  seventh  month  the  growth  of  the  uterus  is  fairh-  uniform,  and  we 
may  draw  qualified  conclusions  as  to  the  duration  of  pregnancy  from  the  height 
of  the  fundus  above  the  pubis.  If  the  fundus  reaches  one-third  the  way  to  the 
navel,  the  pregnancy  is  of  four  months;  if  two-thirds,  five  months;  at  the  navel, 
six  months;  one-third  the  distance  to  the  ensiform,  seven  months;  two-thirds, 
eight  months;  at  the  ensiform,  nine  months.  Now  the  uterus  sinks  do^nl  and 
forward,  the  process  being  called  ''lightening,"  and  reaches  the  level  it  had  at  the 
eighth  month.  Naturally,  the  accuracy  of  these  decisions  is  not  great,  being  dis- 
turbed by  the  inconstancy  of  the  location  of  the  navel,  the  elasticit}'  of  the  belly-wall, 
and  so  many  intra-abdominal  conditions,  the  amount  of  liquor  amnii,  the  size  of 
the  child,  its  position,  etc.  Toward  the  end  of  the  last  trimester  the  shape  of  tJhe 
uterus  alters.  It  becomes  longer,  which  is  due  to  the  head  passing  into  the  newh" 
formed  lower  uterine  segment,  a  change  less  observal)le  in  pluripane  until  actual 
labor  begins.     The  formation  of  the  lower  uterine  segment  is  caused  by  several 


84  PHYSIOLOGY    OF   PEEGNANCY 

factors,  and  may  be  part  of  the  process  of  lightening — the  weight  of  the  child,  the 
intermittent  uterine  contractions,  the  action  of  the  round  ligaments,  the  tightness 
of  the  abdominal  wall,  and  this  is  the  reason  that  lightening  is  more  likely  to  be 
found  in  primiparae. 

The  uterus,  owing  to  absorption  of  some  of  the  liquor  amnii,  conforms  a  little 
more  to  the  shape  of  the  child  and  flattens  at  the  fundus. 


Fig.   110. — Utebcs  at  End  of  Third  Month. 
Shows  long  cervix,  sharp  anteflexion,  and  how  the  fundus  sags  heavily  on  bladder. 

Lightening. — Two  to  three  weeks  before  labor  the  uterus  sinks  downward 
and  forward.  The  women  call  this  "settling"  or  "dropping";  the  technical  term 
is  "hghtening."  It  is  due  to  the  gradual  sinking  of  the  child's  head  into  the  true 
pelvis,  and  occurs  only  in  primiparae  with  normal  pelves,  or  multiparse  with  normal 
pelves  and  well-preserved  abdominal  muscles.  Lightening  may  be  simulated  by 
the  sudden  weakening  of  the  abdominal  wall,  which  sometimes  occurs  late  in  preg-

nancy,  and  by  the  absorption  of  tiie  liquor  amnii.  Botli  of  these  conditions  produce 
the  changes  in  the  contour  of  the  belly,  relieve  the  distress  in  breathing,  and  show 
other  symptoms  attendant  on  true  lightening.     The  diffd'cntial  diagnosis  is  easily

made  by  finding  that  the  head  has  not  engaged  and  that  the  changes  in  the  cervix 
about  to  l)e  descril^ed  have  not  taken  place.  When  the  uterus  sinks,  the  intestines 
and  stomach  have  more  room,  the  epigastrium  is  free,  the  chaphragm  regains  more

nearly  its  usual  level,  the  waist-line  sinks  so  that  the  woman  can  fit  her  skirts  better. 
On  the  other  hand,  the  head  presses  upon  the  bladder  and  rectum,  producing  symp- 
toms from  these  organs;  walking  is  rendered  more  difficult,  and  many  pains  of  a 
neuralgic  nature  and  much  distress  referred  to  the  pelvis  are  complained  of. 


86 


PHYSIOLOGY   OF   PREGNANCY 


On  internal  examination  one  finds  the  vault  of  the  pelvis  filled  by  the  head,  and 

the  cervix,  which  before  was  a  prominent  protu- 
berance on  the  lower  uterine  segment  (Fig.  116), 
now  has  been  flattened  out  against  the  head 
so  that  it  can  hardly  be  recognized  as  apart 
from  the  vagina.  Often  too  the  vagina  is  folded 
on  itself  like  a  loose  cuff,  and  this  might  be  mis- 
taken for  the  dilated  os  or  a  stricture  (Fig.  118). 
Sometimes  lightening  occurs  suddenly,  at- 
tended by  more  or  less  regular  labor-pains. 
The  patient  summons  the  physician,  but  labor 
does  not  occur,  and  sometimes  does  not  come  on 
for  two  weeks.  These  cases  are  not  to  be  con- 
founded ^^^th  protracted  gestation  and  post- 
poned labor  (q.  v.).  Lightening  may  occur  as 
early  as  the  seventh  month,  and  the  head  may 
recede  and  enter  again,  or  later  be  prevented 
from  engaging  by  having  overgrown  the  size 
of  the  inlet  in  the  mean  time.  As  a  rule,  how- 
ever, the  phenomenon  indicates  that  that  head 
is  not  too  large  to  go  through  that  particular 
pelvis,  and,  therefore,  is  always  a  welcome  sign. 
If  the  head  remains  very  low  in  the  pelvis  for 
several  weeks,  it  may  be  molded  to  the  pelvic 
floor,  and  be  flattened  on  the  posterior  parietal 
bone,  a  deformity  more  or  less  permanent. 

The  Cervix  and  Lower  Uterine  Segment. — 

The  unimpregnated  uterus  has  two  parts — the 

corpus,  or  body,  and  the  cervix.     Some  authors 

distinguish  a  third  portion — an  "isthmus,"  at  the  junction  of  the  two,  and  many 

points  are  in  favor  of  the  view  that  such  a  zone  exists.     The  cervix  is  about  as  long  as

When  the  uterus  rises  up  into  the  abdomen,  the  cervical  canal  takes  a  more  vertical

early  as  the  fifth  month  the  external  os  is  often  patulous,  and  will  admit  the  finger 
one-half  inch.  This  is  especially  true  if  the  cervix  has  been  lacerated  and  not 
repaired. 

In  the  seventh  month  the  succulence  which  affected  the  cervix  has  pervaded 
the  whole  pehns,  and  the  outlines  of  the  former  are  hard  to  distinguish.  The  cer\'ix 
has  taken  a  position  higher  and  further  l^ack  in  the  pelvic  cavity.  The  external  os 
always  admits  the  finger  in  multiparae,  and  occasionally  in  primipara?.  The  cer- 
vical canal  is  directed  backward,  but  exceptions  are  not  uncommon.     The  author

has  found  it  sometimes  points  forward  and  upward.  The  internal  os  is  usually 
closed  both  in  primiparse  and  in  inultiparse,  though  it  occasionally  admits  the  tip 
of  the  finger  in  the  latter.  The  cervix  begins  now  to  flatten  out  against  the  fetal 
head,  seemingly  to  be  taken  up  and  used  as  part  of  the  uterine  cavity.  This  is  the 
impression  one  receives  from  the  examining  finger,  but  frozen  sections  prove 
that  it  is  not  always  the  case. 

In  the  ninth  month  the  softening  and  succulence  of  the  cer\Tix  and  neighboring 
tissues  are  greatest,  since  the  venous  congestion  is  at  its  height  and  the  uterine  con- 
tractions of  pregnancy  force  a  great  deal  of  serum  into  the  tissues.     Sometimes

described  under  the  heading  of  Lightening  (p.  84).  The  external  os,  even  in 
primiparaj,  now  usually  admits  the  index-finger,  and  in  most  of  the  cases  the  internal 
OS  will  also  allow  the  finger  to  pass.     This  is  especially  true  of  multiparse  in  whom  two

or  even  three  fingers  may  be  inserted.  The  shape  and  size  of  the  external  os  are 
much  affected  by  previous  laceration  or  scar  formation.  One  will  find  many 
individual  differences.     The  author  has  found  the  cervical  canal  in  an  old  primipara

enlarged  at  the  thirt3'-tliird  week  so  that  the  external  os  admitted  the  middle 
finger  and  the  internal  os  was  the  size  of  a  nickel.  While  the  extreme  softening  and 
the  enlargement  of  the  cervical  canal  indicate  that  labor  is  near,  still,  in  view  of 
what  has  been  said,  absolute  reliance  may  not  be  placed  on  these  signs.  In  the 
last  week  or  ten  days  the  uterine  contractions  often  bring  about  a  true  effaccment 
of  the  cervix,  and  use  it  to  form  the  lower  portion  of  the  uterine  cavity,  thus  antici- 
pating part  of  the  first  stage  of  labor.  This  is  called  "insensible  labor"  by  the 
French,  and  is  a  welcome  finding  to  the  obstetrician,  as  it  facilitates  all  operative 
manoeuvers  should  hasty  delivery  be  necessary.  A  cervix  that  remains  long  and 
tightly  closed  up  until  labor  begins  is  not  normal. 

The  location  of  the  cervix  at  full  term  varies.  Rarely  one  finds  it  anteriorly 
or  at  one  side;  most  often  it  is  in  the  middle  of  the  pelvis  (Fig.  120),  and  manj^ 
times  it  is  back  in  the  hollow  of  the  sacrum  (Fig.  121).  If  it  is  high  up  near  the 
sacrum  and  hard  to  reach  with  the  finger,  the  condition  is  pathologic.     In  cases  of 


Fig.  122. — Cervix  near  Pubis. 


antefixed  uteri,  the  cervix  may  be  located  above  the  promontory  in  the  abdominal 
cavity. 

The  relation  of  the  cervix  to  the  lower  uterine  segment  has  been  the  subject 
of  conflicting  theories  since  1746.  Mauriceau  and  Levret  taught  that  from  the 
sixth  month  the  upper  portion  of  the  cervix  was  unfolded  or  effaced,  dra\^^l  up,  and 
used  to  form  part  of  the  uterine  cavity,  until  at  term  only  a  small  part  of  the  cervix 
was  left.  Stoltz,  in  1826,  denied  this,  claiming  that  the  cervix  remained  closed 
until  near  the  advent  of  labor.  Both  opinions  were  based  on  the  results  of  vaginal 
exploration.  Bandl,  in  1876,  as  the  result  of  examination  of  many  uteri,  reaffirmed 
the  old  theory,  while  Schroder,  Ruge,  Leopold,  and  very  many  others  have  sought 
to  prove  that  the  cervix  does  not,  during  pregnancy,  form  part  of  the  uterine  cavity. 
Bayer  has  done  the  most  work  on  the  subject,  and  his  conclusions  are  slowly  gaining 
more  and  more  acceptance.  They  are  supported  by  the  latest  and  best  frozen 
section  by  Bumm  and  Blumreich.  If  one  examines  a  gravida  in  the  last  month  of 
pregnancy,  one  will  often  find  conditions  as  indicated  in  Fig.   123.     The  finger

passes  along  the  cervical  canal,  meets  a  ring  at  Os  I,  generally  termed  the  internal 
OS,  and,  if  this  point  does  not  offer  resistance,  enters  the  ca\aty  of  the  uterus,  finds 
the  membrane  but  lightlj-  adherent  to  the  lower  pole  of  the  same,  and  about  an 
inch  from  the  internal  os,  at  the  level  of  the  pelvic  inlet,  encounters  a  slight  ridge, 
C.R.,  above  which  the  hard,  muscular  uterus  is  felt.  The  portion  from  Os  I  to 
C.R.  has  been  called  the  lower  uterine  segment,  and  its  origin  has  been  much  dis- 
cussed— its  existence  even  been  questioned.  The  old  theory,  supported  by  Mauri- 
ceau,  Bandl,  Bayer,  et  al.,  was  that  the  lower  uterine  seg-ment  was  the  expanded 
upper  portion  of  the  cervix.  The  newer  theory,  supported  b}^  Stoltz,  Schroder, 
Hofmeier,  et  al.,  was  that  the  lower  uterine  segment  came  from  the  uterus  itself, 
its  lower  portion  being  thus  differentiated.  Both  theories  have  this  in  common, 
that  there  is  such  a  zone  as  the  lower  uterine  segment,  and  that  it  is  different  in 
structure  and  formation  from  the  fundus  uteri.  Braune  and  Bumm  claim  that  it  is 
formed  during  labor,  the  cervix  and  uterus  remaining  unchanged  until  pains  begin.

As  Bandl  remarks,  it  is  hardly  to  be  thought  that  so  mighty  an  alteration  could  be 
wrought  in  the  small  cervix  in  the  few  hours  of  labor.  Aschoff  describes  a  portion 
of  the  uterus — an  isthmus — between  the  corpus  and  cervix,  partaking  of  the  char- 
acter of  both,  and  claims  that  this  forms  the  lower  uterine  segment.  The  literature 
on  this  subject  is  immense,  and  on  reading  it  one  is  struck  with  the  lack  of  uni- 
formity^ in  nomenclature,  in  the  lack  of  anatomic  basis  for  the  various  divisions  of 
the  cervix  and  corpus  uteri  graviditatis,  and  with  the  superficiality  of  many  of  the 
examinations  of  the  specimens. 

The  OS  internum  of  the  non-pregnant  uterus  is  easily  determined;  not  so  that 
of  the  pregnant  organ.  Not  the  sharp  edge  of  the  mucous  membrane  of  the  cervix 
at  the  so-called  internal  os;  not  the  firm  attachment  of  the  peritoneum  to  the  uter- 
ine muscle;  not  ^the  location  of  the  circular  vein;  not  the  formation  of  decidua; 
not  the  mucin  reaction  of  the  cervical  glands — distinguishes  cervix  from  corpus,  or 
lower  uterine  segment  from  cervix.     The  most  certain  difference  is  the  distribution

93 


of  the  muscle-fibers,  and  Bayer  has  shown  that  these  alter  their  position  in  quite 
characteristic  fashion  in  the  latter  weeks  of  pregnancy. 

It  is  probable,  in  some  cases,  multiparae  notably,  that  the  mucous  membrane 
and  a  few  layers  of  muscle — mostly  circular — of  the  cervix  remain  unchanged  until 
ver}'  near  the  advent  of  labor  pains.  This  gives  the  sensation  of  a  long  canal  and 
of  a  closed  internal  os,  a  condition  well  knowTi  to  Bandl.  It  is  just  as  probable  that 
the  outer  layers  of  cervical  muscle  are  drawn  up  and  expanded  during  the  latter 
months  of  pregnancy,  to  form  part  of  the  uterine  cavity — the  so-calletl  lower 
uterine  segment.     The  upper  boundary-  of  this  zone  is  the  "contraction  ring,"  or

the  lower  edge  of  the  contracting  muscle  of  the  corpus;  the  lower  Ijoundary  is  the 
so-called  internal  os  of  the  cervix,  the  edge  of  the  cervical  mucous  membrane.  This 
zone  is  sometimes  covered  with  decidua,  but  the  membranes  are  loosely  attached  to 
it,  showing  its  late  formation.  It  has  httle.  if  any,  contractile  power.  The  mov- 
ability  of  the  muscular  layers  on  each  other  permits  the  employment  of  cervical 
fibers  for  the  formation  of  the  lower  uterine  segment.  It  is  probable,  too,  that 
sometimes,  oftener  in  primiparse,  the  cervical  mucous  membrane  is  also  dra^\Ti  up 
into  the  lower  uterine  segment.  In  this  case  one  finds  portions  of  the  plica  palmatse 
spread  out  in  the  lower  uterine  segment,  and  one  may  even  find  the  mucous  mem- 


94  PHYSIOLOGY    OF   PREGNANCY 

brane  changed  into  decidua.  It  is  certain  that  sometimes  the  cervix  remains  un- 
changed, except  to  soften  and  hypertrophy,  and  tightly  closed  until  the  advent  of 
hard  labor.  These  cases  are,  according  to  Bayer,  pathologic,  and  the  author  agrees 
with  him  (Fig.  123). 

That  the  changes  in  the  cervix  during  pregnane}^  are  not  constant  and  typical 
will  not  surprise  him  who  remembers  the  variously  sized  and  shaped  cervices  he 
meets  in  the  routine  of  gvTiecologic  examinations,  and  one  must  agree  with  Bayer 
that  sometimes  the  cervix  unfolds  in  pregnane^'  and  sometimes  it  does  not. 

During  labor  the  differentiation  in  the  uterus  becomes  marked  and  unquestion- 
able. The  corpus  contracts  strongly,  the  lower  uterine  segment  feebly,  the  cervix 
not  at  all;  thus  two  zones  are  formed — an  upper,  contracting,  and  a  lower,  dilating. 
In  the  consideration  of  the  mechanism  of  laljor  this  subject  will  again  come  up. 

Changes  in  the  Physiology  of  the  Uterus. — During  pregnancy  the  uterus  ac- 
quires no  new  functions;  those  it  has,  however,  are  much  developed.  Menstrua- 
tion normally  ceases  during  pregnancy. 

The  sensibility  varies  in  different  women.  Unless  diseased,  the  organ  is  not 
tender.  In  neurotic  patients  the  lightest  palpation,  even  the  fetal  movements, 
evoke  pain.     In  labor  the  uterus  is  more  sensitive. 

Irritability  is  that  property  which  makes  the  uterus  respond  to  external  stimu- 
lation by  contracting.  Pregnancy  develops  this  quality,  but  it  also  varies  in  differ- 
ent women.  In  some  the  ordinary  abdominal  examination  evokes  contractions; 
in  others  most  powerful  external  and  internal  stimuli  produce  little,  if  any,  effect. 
This  is  best  observed  when  we  try  to  bring  on  labor. 

The  dilatability  of  the  uterus  increases  very  much  during  pregnancy,  and  even 
when  the  uterus  seems  well  filled  by  the  ovum  it  can  still  stretch  to  hold  a  con- 
siderable amount  of  extra  fluid.  This  is  shown  by  the  enormous  acute  distention  in 
polyhydramnion  and  in  the  accumulation  of  large  quantities  of  blood  in  cases  of 
abruptio  placentae. 

Contractility  increases  as  pregnancy  advances.  Acting  on  impulses  coming 
through  the  nervous  system,  the  uterus  contracts  and  relaxes.  We  note  this  power 
in  the  unimpregnated  uterus  when  it  expels  clots,  membranes,  or  fibroids.  As  early 
as  the  fifth  week  of  gestation  the  contractions  of  the  uterus  are  perceptible  to  the 
examining  finger.  These  are  painless,  last  twenty  to  thirty  seconds,  sometimes  a 
few  minutes,  and  may  be  observed  to  recur  at  irregular  intervals  up  to  the  advent  of 
labor,  when  they  become  regular,  painful,  and  more  powerful.  The  contractions 
are  involuntary,  but  are  sometimes  affected  by  the  nervous  condition  of  the  woman. 
They  may  continue  postmortem  for  a  brief  period. 

Retractility  is  a  function  of  the  uterine  muscle  not  fully  understood.  It  is 
that  power  which  enables  the  uterine  wall  to  close  down  on  its  diminishing  cavity. 
This  is  brought  about  by  a  microscopic  felting  together  of  the  muscle-fibers  and  a 
superimposition  of  the  muscular  lamellae.  This  power  is  manifested  only  in  parturi- 
tion. A  retracted  uterus  cannot  be  completely  expanded  without  danger  to  its 
structure.  The  property  of  retractility  lies  either  in  the  muscle  itself,  or  it  is  evoked 
through  the  nervous  mechanism — probably  the  latter,  since  it  seems  to  be  affected 
by  the  same  influences  as  contractility. 

Elasticity  is  the  ability  of  the  uterine  wall  to  return  to  a  condition  of  rest  after 
being  distended.     It  must  be  sharply  differentiated  from  retractility. 

The  round  ligaments  are  part  of  the  uterine  muscle,  and  h^^jertrophy  with  it. 
Late  in  pregnancy  they  may  be  as  thick  as  the  little  finger,  and,  owing  to  the  high 
location  of  the  fundus,  they  run  vertically.  When  the  placenta  is  situated  on  the 
posterior  wall,  the  round  ligaments  are  felt  converging  toward  the  fundus  on  the 
anterior  wall  of  the  uterus,  and  when  the  anterior  wall  is  occupied  by  the  placenta, 
the  ligaments  are  pushed  to  the  sides.  The  round  ligaments  contract  synchro- 
nously with  the  uterus,  and  serve  to  moor  the  latter  organ  to  the  pelvis  during  labor. 


CHANGES  DUE  TO  PREGNANCY 


95 


In  pregnancy  no  such  action  is  observable  except  in  pathologic  cases — as  retrover- 
sion. 

The  uterosacral  ligaments  normall>'  vary  much  in  their  development  and  in 
the  place  of  insertion  on  the  uterus.  They  too  are  part  of  the  uterine  musculature 
and  hypertrophy  in  pregnancy.  The  part  played  by  these  ligaments  as  suspensors 
of  the  uterus  has  been  much  exaggerated.  Normally,  they  are  relaxed  and  are  put 
^n  the  stretch  only  when  the  uterus  is  dra^^'n  or  forced  doA\Ti  or  up.  If  the  displace- 
ment is  kept  up,  they  stretch  and  tear.  During  labor,  however,  they  contract  with 
the  uterus,  assisting  to  hold  it  in  the  proper  axis  of  the  pelvis,  and  they  aid  in  the 
dilatation  of  the  lower  uterine  segment  and  cervix. 

The  broad  ligaments  are  also  strengthened  by  the  addition  of  muscular  fibers, 
particularly  around  the  arteries  and  veins.     The  two  peritoneal  layers  are  separated

by  the  development  of  the  uterus,  so  that  a  much  larger  portion  of  this  organ  is  un- 
covered at  the  sides. 

The  pelvic  connective  tissue  loses  its  fat ;  the  unstriped  muscle-fibers  develop 
more  abundantly  in  it ;  the  lymph-spaces  are  larger;  there  is  a  serous  imbil)ition  of 
all  the  tissues,  and  the  whole  pelvis  is  congested  and  more  succulent.  Immense 
veins  develop  in  and  around  the  vagina  and  cervix,  sometimes  to  a  pathologic  ex- 
tent. The  sides  of  the  uterus  may  bulge  with  soft  venous  swellings.  During  labor 
these  may  burst,  forming  hematomata,  and  after  labor  they  may  thrombose  and 
give  rise  to  emboli. 

The  peritoneum  grows  with  the  uterus,  a  true  h>i3erplasia  occurring.  In 
pathologic  cases  the  peritoneum  may  not  grow,  and  tears  result.  After  delivery 
the  peritoneum  lies  wrinjded  in  more  or  less  t^-iDical  directions  on  the  contracted

uterus,  corresponding  to  the  course  of  the  muscle-fibers  (Fig.  125).  "Walker,  in 
1887,  and  Schmorl  call  attention  to  decidua-like  growths  on  the  peritoneum  of 
Douglas'  culdesac,  the  posterior  wall  of  the  uterus,  the  tubes,  ovaries,  and  omentum. 
The  author  has  found  them  on  the  anterior  abdominal  wall  in  cases  of  cesarean 
section.  They  may  be  2  to  3  mm.  thick,  are  just  under  the  endothelium,  raising  it 
up,  resembling  miliary  tubercles,  and  may  be  pedunculated.  They  are  derived 
from  the  connective  tissue,  and  may  be  cystic  or  even  calcareous.  One  finds  these 
structures  from  the  third  to  the  tenth  month,  and  the  remains  persist  for  several 
weeks  after  delivery. 

The  tubes,  which  ordinarily  vary  in  length  from  5  to  19  cm.,  are  stretched  out 
in  pregnancy,  hanging  almost  perpendicularly  at  the  sides  of  the  uterus.  There  is 
no  hypertrophy  of  the  muscle-fibers,  but  much  increased  vascularity  and  succulence. 
A  moderate  decidual  change  of  the  mucous  membrane  has  been  observed  even  with 
intra-uterine  pregnancy.  The  uterine  end  is  usually  closed,  but  the  fimbriated  end 
is  open.  The  patulousness  of  the  tubes  is  closely  associated  with  the  question  of 
the  possibility  of  superfecundation. 

The  ovaries  are  enlarged,  especially  the  one  containing  the  corpus  luteum. 
In  the  early  months  the  corpus  luteum  may  be  palpated — of  course,  onh^  in  favor- 
able cases.  In  the  later  months  one  may  feel  the  ovary  through  the  abdominal 
wall  hanging  on  the  side  of  the  uterus.  The  right  one  is  less  easily  felt.  They  are 
always  quite  tender.  The  microscopic  changes  in  the  ovary  are  edema,  vasculariza- 
tion, decidua-like  formations  under  the  tunica  albuginea.  Ovulation  does  not  in- 
variably cease  during  pregnancy,  as  was  formerly  taught. 

The  vagina  increases  in  length  and  capacity  by  a  real  eccentric  hypertrophy. 
It  becomes  more  distensible,  the  elastic  fibers  increasing  in  amount,  and  the  tissues 
becoming  infiltrated  with  serum.  The  rugse  deepen,  the  papillae  swell,  so  that 
sometimes  they  are  palpable  as  small  granules.  In  pathologic  cases  a  vaginitis 
granulosa  may  develop,  and  in  cases  of  gonorrhea  the  surface  may  feel  like  a  nutmeg- 
grater.  The  veins  enlarge,  the  venules  also,  giving  the  surface  a  deep  wine  color 
(diagnostic  of  pregnancy),  and  this  engorgement  is  attended  by  pronounced  secre- 
tion or  leukorrhea. 

The  upper  portion  of  the  vagina  enlarges  as  pregnancy  advances,  so  that  in  the 
later  months  it  is  usually  possible  to  touch  the  sides  of  the  pelvis  with  the  stretched 
fingers  or  a  dilating  pelvimeter.  When  the  uterus  ascends,  the  vagina  is  drawn  up; 
when  the  head  enters  the  pelvis  in  the  last  month  of  pregnancy,  the  vagina  is  pushed 
down  and  often  thrown  into  the  circular  folds,  which  may  simulate  the  dilating 
cervix  (Fig.  118).  The  anterior  vaginal  wall  and  thickened  urethrovaginal  septum 
may  prolapse  through  the  patulous  vulva.  Similar  changes  are  seen  on  the  vulva — 
softening,  dark  coloration,  varices,  pigmentation,  thickening,  enlargement,  in- 
creased secretion  of  all  its  glands. 

The  pelvic  floor  takes  part  in  the  general  im]3il:)ition  of  the  pelvis.  The  levator 
ani  becomes  less  rigid,  more  distensible.  The  fat  in  the  ischiorectal  fossa  is  partly 
absorbed  by  the  end  of  pregnancy,  but  the  infiltration  with  serum  causes  a  pro- 
nounced swelling  and  sagging  of  the  perineum.  This  sagging  of  the  perineum  below 
a  line  drawn  from  the  under  surface  of  the  pubis  to  the  tip  of  the  sacrum  is  called 
pelvic  floor  projection  (Fig.  126).  Other  conditions  cause  an  increase  of  pelvic  floor 
projection,  such  as  pelvic  tumors,  marked  intra-abdominal  pressure,  but  in  preg- 
nancy it  is  most  manifest,  and  in  cases  of  incarceration  of  the  gravid  uterus  one  meets 
the  greatest  depression  of  the  tissues.  The  pelvic  floor  projection  during  labor  will 
be  considered  later. 

The  bladder  is  much  concerned  in  the  changes  wrought  by  pregnancy.  In  the 
early  months  the  fundus  uteri  lies  upon  it,  but  with  no  greater  weight  than  the  in- 
testines. A  certain  amount  of  traction  is  exerted  by  the  retroposed  cervix  on  the 
neck  of  the  bladder,  and  this,  with  the  congestion  of  the  parts,  explains  the  fre-

quent  urination  complained  of  l:)y  the  women  at  this  period.  Cystoscopically,  the

is  darker,  and  one  experienced  in  the  use  of  the  instrument  may  suspect  the  preg-

nancy  from  the  appearance  of  the  congested  and  newly  vascularized  bladder  mucosa. 
Varicose  veins  in  the  base  of  the  bladder  are  sometimes  found.  In  the  later  months 
they  may  give  rise  to  hemorrhage.  Even  after  the  uterus  has  risen  into  the  abdo- 
men the  bladder  remains  a  pelvic  organ,  unless  distended,  when  it  is  flattened  out

against  the  abdominal  wall.  In  these  cases  the  bladder  assumes  a  saddle  shape, 
extending  up  to  either  side  of  the  uterus — more  toward  the  right.  This  is  determin- 
able by  the  cystoscope  or  by  illuminating  the  filled  bladder  and  ol)serving  the  abdo- 
men in  a  dark  room.  The  area  of  redness  on  the  belly-wall  shows  the  outline  of 
the  bladder.  With  the  development  of  the  lower  uterine  segment  the  attachment 
of  the  bladder  to  the  uterus  is  loosened  and  the  bladder  is  stripped  off  the  wall 
of  the  latter.  In  labor  the  uterus  retracts  still  further  away  from  the  bladder — 
sometimes  so  far  that  the  latter  comes  to  lie  on  the  vagina.  These  facts  were  de- 
termined clinicalh^  in  cases  of  extraperitoneal  cesarean  section.  During  the  latter 
part  of  the  first  stage  of  labor  the  peritoneum  of  the  anterior  culdesac  may  be  partly 
stripped  off  the  bladder.  When  the  head  enters  the  pelvis  in  the  last  month,  it 
may  press  directly  on  the  liladder  or  distort  its  base,  thus  giving  rise  to  the  fre- 
quent urination  so  often  noted.  Perhaps  the  diminished  capacity  of  the  organ 
is  also  causative.  The  bladder,  flattened  between  the  head  and  pelvis,  bulges  out 
at  either  side,  especially  the  right,  when  filling. 

The  ureters  are  enlarged  early  in  pregnancy.  Thickening  is  one  of  the  diag- 
nostic signs.  They  are  displaced  to  the  side  of  the  pelvis,  and  may  be  felt  on  })i- 
manual  examination  as  two  cord-like,  tender  structures,  coursing  between  the  cervix 
and  pelvic  wall.  Late  in  pregnancy  they  may  be  felt  lying  against  the  lower  uterine 
segment  and  the  fetal  head.  Halbertsma  claimed  that  the  ureters  frequently  suffer 
compression  during  the  later  months  of  pregnancy,  and  that  eclampsia  is  due  to  the 
damming  back  of  the  urine.  At  no  time  can  the  uterus  directly  compress  the  ureters, 
and,  further,  the  weight  of  the  uterus  is  not  greater  than  that  of  the  intestinal  mass. 
The  entry  of  the  fetal  head  into  the  pelvis  in  the  last  month  distorts  the  course  of 
the  ureter  or  kinks  or  stretches  it,  and  this  may  interfere  with  the  passage  of  urine. 
Cystoscopically,  the  ureteral  openings  in  the  bladder  appear  elevated,  thickened, 
and  deeply  congested. 

The  pelvic  girdle  is  affected  by  the  changes  of  pregnancy.  The  author  has 
determined  an  actual  increase  of  the  size  of  the  pelvic  cavity.  Measurements  taken 
of  contracted  pelves  before  conception,  and  just  before  labor,  \vill  often  show  this, 
and  women  in  whom  labor  was  predicted  as  impossible  may  have  spontaneous  or 
easy  operative  deliveries.  The  constitution  of  the  pelvic  bones  during  pregnancy 
is  altered  similarly  to  the  pathologic  osteomalacia.  Occasionally  there  is  an  irreg- 
ular deposit  of  extra  bone  under  the  periosteum — the  puerperal  osteophytes  of 
Rokitansky. 

The  pelvic  articulations  undergo  marked  changes.  Hippocrates  knew  that 
they  softened  and  became  looser,  and  he  believed  that  parturition  was  difficult  if 
this  relaxation  did  not  occur.  Perhaps  part  of  the  enlargement  of  the  pelvic  circle 
above  mentioned  is  due  to  the  thickening  of  the  cartilages  of  the  joints.  Normally, 
and  in  man,  there  is  a  slight  movability  of  the  pelvic  joints,  but  in  pregnancy  this  is 
increased  and  during  labor  it  is  greatest.  The  tissues  of  the  joint  imbibe  fluid,  the 
capsule  thickens,  the  vascularity  is  increased,  and  there  is  an  augmentation  of 
synovia.  It  is  to  be  noted  that  these  changes  are  most  marked  in  w^omen  with 
varicose  veins  of  the  pelvis.  The  pubic,  sacrococcygeal,  and  sacro-iliac  joints  are 
affected  in  the  order  named.  In  guinea-pigs  these  changes  are  part  of  the  preg- 
nancy and  parturition,  and  may  be  so  pronounced  that  the  bones  of  the  pubis  may 
separate  so  far  as  to  allow  the  animal's  legs  to  lie  alongside  the  body  on  the  table. 
In  cows  the  "sinking  of  the  rump"  informs  the  veterinarian  that  delivery  is  at  hand. 
In  women  an  actual  enlargement  of  the  pelvis  in  labor  occurs  only  in  very  slight 
degree,  but  the  softening  of  the  joints  allows  free  motion  of  the  bones  and  thus  a 
certain  configuration,  which  facilitates  the  delivery. 

Many  women  in  the  later  months  of  pregnancy  complain  of  pain  in  the  pelvic 
joints,  a  waddling  gait,  and  difficulty  in  walking.  Examination  will  usually  show 
tenderness  over  the  pubes,  and  riding  of  the  two  bones  on  each  other  when  the  pelvis 


CHANGES   DUE   TO    PREGNANCY

is  strongly  rocked  from  siilc  to  side,  or  even  a  groove  showing  a  larger  degree  of 
separation.     (See  Relaxation  and  Rupture  of  the  Pelvic  Joints.) 

The  abdominal  wall  distends  as  the  pregnancy  advances,  and  grows  thinner, 
especially  around  the  navel.  Experiments  by  Kraus  have  shown  that  the  tension  is 
in  the  direction  of  radii  from  the  navel.  In  primiparie  the  abdominal  walls  are 
tenser  antl  sag  less  than  in  women  who  have  borne  children.  Sometimes  the  linea 
alba  gives  way  to  the  strain,  the  recti  muscles  separate,  and  the  pregnant  uterus 
falls  forward  between  them,  covered  only  by  a  thin  layer  of  skin  and  peritoneum. 
This  is  called  "rupture"  by  the  laity.  The  belly  becomes  pendulous,— "re/?/7-e  en 
hesace, " — and  not  seldom  the  condition  gives  rise  to  dystocia.  Any  tendency  to 
hernia  is  aggravated  by  pregnancy,  Ijut,  during  the  period  the  uterus  usually  pushes 
up  and  keeps  away  the 
gut  and  omentum  from 
the  hernial  openings — 
that  is,  unless  these  are 
adherent  to  the  sac. 

In  90  per  cent. 
(Crede),  and  in  practi- 
cally all  cases  of  the 
author,  the  skin  shows 
smooth,  silvery,  or 
pearly  white  or  violet 
broad  lines,  called  striae 
or  lineae  albicantes  gravi- 
darum. The  lines  are 
curved,  irregular,  some- 
times confluent,  and 
show  a  fine  transverse 
fibrillation.  They  are  ar- 
ranged more  or  less  con- 
centrically, but  some- 
times radially  around 
the  navel,  especiall}'  on 
the  lower  abdomen.  Near 
Poupart's  ligament  they 
are  alwaj^s  broader  and 
deeper  in  color.  One  finds 
them  on  the  nates,  the 

thighs,  more  on  the  anterior  aspect,  but  sometimes  on  the  posterior  too,  and  as  far 
down  as  the  knees.  The  breasts  also  show  them,  arranged  radially  to  the  nipple. 
Blonds  are  more  affected  than  brunets,  primiparae  more  than  multiparae,  fat 
women  more  than  lean,  large  women  more  than  small.  The  number  depends  also 
on  the  degree  of  abdominal  distention,  but  there  are  other  factors  in  the  causation 
than  mere  abdominal  distention,  because  in  cases  of  immense  abdominal  enlarge- 
ment due  to  ovarian  tumors  or  ascites  the  striae  are  not  constant.  Formerty  they 
were  considered  positive  proof  of  preexisting  pregnancy,  but  this  is  not  true,  since 
they  occur  in  the  following  conditions:  rapid  accumulation  of  fat  at  any  period,  as 
at  puberty;  they  are  found  in  men  (6  per  cent.);  dropsy  and  ascites;  abdominal 
tumors;  unusually  rapid  gro^\i;h  of  the  long  bones  may  develop  them  at  the  epi- 
physes; after  typhoid  fever.  If  the  lineae  are  marked  and  with  t^-pical  distribution, 
the  presumption  of  previous  pregnancy  is  strong,  but  never  certain.  The  author 
has  seen  striae  on  the  breasts  of  a  virgin.  New  striae  may  appear  among  the  old. 
The  author  has  observed  lineae  gravidarum  in  the  sixth  month.  Histologically,  one 
finds  the  connective  tissue  of  the  cutis  and  subcutis  stretched,  sometimes  torn,  and

PHYSIOLOGY   OF   PREGNANCY 


the  former  rhomboid  arrangement  of  the  fibers  changed  to  a  more  parallel  disposi- 
tion of  the  strands  across  the  striae.  The  elastic  fibers  are  always  torn,  and  the  re- 
tracted ends  found  at  the  edge  of  the  striae.  The  lymph-spaces  are  compressed  and 
arranged  parallel.  Perhaps  this  explains  the  tendency  of  the  lineae  to  become  drop- 
sical. The  papillae  are  flattened,  sometimes  completely,  and  are  also  arranged  in 
transverse  rows.  The  epitlermis  is  thinned.  In  brunets  and  colored  women  there 
is  a  tendency"  to  pigmentation  of  the  striae.  Stratz  says  that  savage  women  do  not 
have  striae,  and  advises  massage  with  oil  as  a  preventive. 

The  Physics  of  the  Abdomen. — The  pressure  in  the  belly  varies  very  little  from 
that  outside,  and  depends  on  the  tonicity  of  the  abdominal  walls.  In  the  relaxed 
horizontal  position  the  abdominal  walls  support  a  pressure  equal  only  to  the  weight 
of  the  viscera,  which,  being  practically  semifluid,  seek  the  lowest  portions  of  the 
cavity.  In  this  position  there  is  a  slight  increase  of  intra-abdominal  pressure  with 
inspiration,  and  a  slight  decrease  during  expiration. 

In  the  erect  position  there  is  a  slight  increase  of  intra-abdominal  pressure  be- 
cause the  muscles  are  on  tension,  and 
this  is  augmented  by  inspiration, 
forced  expiration,  as  by  exercise,  ex- 
pulsive efforts,  defecation,  vomiting, 
])arturition.  The  development  of 
tumors  in  the  bellj^,  as  fibroids,  cysts, 
pregnancy,  increases  intra-abdom- 
..:_^,^_.,  inal  pressure.     In  addition  the  lower 

jtj^BB/^^  portions  of  the  abdomen,  in  the  erect 

,^^^^^^^lBb  '^iH     position,  sustain  the  weight  of  the

^I^^^HJI^^K  -ll     Therefore  intra-abdominal  pressure 

^^^^^^^SF  is  not  the  same  at  all  points.     The 

changes    in    the    pressure    brought 

aliout  l3y  respiration  are  transmitted 

throughout   the    abdomen,  and  are 

evident  on  the  perineum  and  organs 

resting  on  the  pelvic  floor,  uterus,  and 

^^  bladder.     The   organs   in  the  belly

shows  primary  and  secondary  areolae.  pheric  pressurc.     They  are  fastened 

to  the  firm  parietes  by  ligaments 
and  floated  on  each  other,  getting  indirect  support  from  the  abdominal  muscles 
and  pelvic  floor.  In  the  knee-chest  position  the  weight  of  the  liver  and  intestines 
falling  toward  the  chest  produces  a  negative  pressure  in  the  abdomen.  If,  now, 
the  belly,  vagina,  rectum,  and  bladder  are  opened,  air  rushes  in  and  distends  them. 
We  use  this  position  therapeutically. 

The  Breasts.— In  the  embryo  of  six  weeks  there  is  found  a  line  of  cells  running 
from  the  axilla  to  the  groin,  and  called  the  linea  or  crista  lactea.  From  the  chest 
portion  of  this  the  breasts  develop.  Accessory  breasts  and  supernumerary  nipples 
are  almost  always  found  in  this  line  on  either  side,  and  indicate  a  tendency  to  revert 
to  a  lower  order  in  human  development. 

An  ingro^vth  of  epithelial  cells,  which  later  Ijecome  tubulated,  marks  the  site 
of  the  mamma.  In  the  fetus  at  five  months  the  gland  consists  simph'  of  a  collection 
of  ducts  which  open  at  one  spot — the  future  nipple.  This  spot  is  depressed;  thus 
an  inverted  nipple  in  the  adult  is  simply  one  retarded  in  development.  Even  at 
seven  months  the  ducts  are  branched,  and  at  term  they  divide  two  or  three  times. 
These  primitive  ducts  represent  the  future  lol)ules.     Hardly  any  acinous  structure

exists  at  birth,  but  the  tuljulcs  are  capable  of  secreting  milk  and  colostrum  which 
do  not  differ  in  composition  from  those  of  the  mother.  The  gro\\-th  of  the  gland  is 
very  slow  until  puberty.  Then  acini  develop  in  the  primitive  tubules,  each  of 
which  becomes  a  tubuloracemose  gland,  and  thus  the  breast  comes  to  he  made  up 
of  distinct  lobules  embedded  in  a  fat  cushion.  Each  lobe  empties  on  the  surface 
of  the  now  prominent  nipple  by  a  duct.  Before  opening  on  the  nipple  each  duct 
dilates  a  little — the  sinus  lactifcrus.  There  are  15  to  20  ducts.  The  nipple  is  a 
muscular  organ,  and  is  covered  by  delicate  pigmented  skin,  is  quite  vascular,  and  at 
the  base  is  surrounded  by  unstriped  muscle-fibers  which  unite  with  those  of  the 
nipple  itself  and  thus  produce  the  erection  of  the  same.  For  a  varying  distance 
around  the  nipple  the  skin  is  very  delicate,  more  or  less  pigmented,  and  raised  from 
the  fascia  covering  the  mammary  gland  by  soft  connective  tissue  and  fat.     This  is

the  areola.  Embedded  in  this  areola  lie  tiny  milk-glands,  each  opening  on  the  sur- 
face by  a  microscopic  duct,  ^Montgomery's  tubercles.  Sebaceous  and  sweat-glands 
are  also  found. 

With  the  advent  of  pregnancy  the  glands  take  on  renewed  growth,  and  as  early 
as  the  second  month  a  change  may  Ije  noted.  The  breasts  increase  in  size  and  sensi- 
bilit.y;  the  hard,  tense  feel  of  the  virgin  gland  is  lost;  it  softens  and  sags.  The 
lobules  become  more  marked,  due  to  enlargement,  development  of  acini  in  the 
periphery,  and  softening  of  the  connective  tissue  and  fat  around  them.  The 
acinous  formation  on  the  tubules  in  the  center  of  the  gland  is  especially  marked 
during  pregnancy,  there  being  both  In^Dcrplasia  and  hy])ertrophy.  The  veins  en- 
large and  are  seen  as  bluish  streaks,  especially  at  the  perijihery,  and  here  striae  often 
(67  per  cent.)  develop.  Hypertrophy  of  the  lymph-system  is  also  a  feature.  The 
nipple  becomes  more  erectile,  and,  with  the  areola,  l)ccomes  more  deeply  pigmented. 


102 


PHYSIOLOGY   OF   PREGNANCY 


The  base  of  the  areola  becomes  puffy,  raising  the  surface  above  that  of  the  rest  of 
the  gland,  and  the  milk-glands  of  JMontgomery  enlarge  prominently.  Occasionally 
a  droplet  of  secretion  may  be  expressed  from  them.  Around  the  primary  areola, 
especially  in  brunets,  a  secondary  areola,  less  pigmented,  sometimes  develops.  It 
resembles  "dusty  paper  sprinkled  with  drops  of  water."  The  clear  spots  are  due 
to  lack  of  pigment  around  the  openings  of  sweat  and  sebaceous  glands.  From  the 
early  months — and  the  time  varies — a  little  clear,  sticky  fluid  may  be  expressed  from 
the  nipple.  Later  this  is  mixed  with  yellow  material.  It  is  called  colostrum. 
Often  it  oozes  out  and  dries  into  branny  scales  on  the  nipple.  Unless  cleaned  off, 
these  sometimes  decompose  and  give  rise  to  sore  nipples,  even  in  pregnancy. 

The  shape  of  the  l)reast  varies  much  in  women,  and  also  at  different  periods  of 
life.  In  young,  non-pregnant  women  they  sometimes  are  hemispheric  and  promi- 
nent. In  old  women  and  in  the  later  months  of 
pregnancy  they  are  pendulous.  In  some  colored 
races  they  are  like  long  sacs,  and  they  may  be 
thrown  over  the  shoulder,  for  a  child,  carried  on 
the  back,  to  nurse  from.  Some  breasts  are  large, 
others  small,  which  depends  on  the  amount  of 
gland  tissue  and  fat,  of  which  there  is  sometimes 
more  of  one  than  of  the  other.  The  right  breast 
is  sometimes  larger  than  the  left,  and  vice  versa. 
The  mammary  glands  may  be  considered 
modified  skin-glands,  with  a  fetal  origin  similar 
to  the  sebaceous  glands  (Basch).  Sometimes  we 
find  supernmnerary  glands  and  nipples  above  and 
below  the  normal  one.  This  is  called  poljanastia, 
and  is  rare.  Accessory  glands  and  nipples  are  usu- 
ally found  in  a  line  running  from  the  axilla  onto  the 
abdomen — the  crista  lactea  already  referred  to; 
this  and  embryologic  studies  indicate  that  man 
had  at  one  time  a  line  of  glands  similarly  to  some 
of  the  lower  animals.  Up  in  the  axilla  there  is 
often  an  aberrant  piece  of  the  mammary  gland, 
which  sometimes  swells  and  becomes  painful  when 
lactation  starts.  It  is  often  mistaken  for  a  Ijmiph- 
gland.     It  may  enlarge  outside  of  pregnancy. 

When  the  child  is  delivered  and  lactation  be- 
gins, the  breasts  reach  their  highest  development, 
but  we  will  leave  the  consideration  of  this  until 
we  discuss  the  changes  of  the  puerperium.  Star- 
ling believes  that  the  growth  of  the  mammae 
during  pregnancy  is  due  to  the  action  of  a 
"mamma  hormone,"  developed  in  the  growing 
fetus,  carried  to  the  ])reasts  by  the  blood,  and  there  acting  specifically  on  the 
gland-cells.  In  the  Blazek  united  twins,  though  only  one  was  pregnant,  in  l^oth  the 
breasts  were  enlarged  and  secreted  milk.  The  breasts  possess  an  internal  secretion. 
It  may  have  some  relation  to  the  inauguration  of  labor.  Extracts  of  the  mamma 
have  been  employed  therapeutically.

GENERAL  CHANGES  IN  THE  MATERNAL  ORGANS 

Mauriceaii  called  pregnancy  a  disease  of  nine  months'  duration,  and  there  is 
much  truth  in  the  statement.  Generally,  the  pregnant  state  and  labor  are  looked 
upon  as  physiologic,  and  in  perfectly  healthy  women  they  may  be  so.  No  other 
function  of  the  body  is  attended  by  such  dangerous  possibilities  or  is  so  easily  de- 
ranged, so  that  one  must  always  bear  in  mind  how  close  to  the  borderland  of 
pathology  the  obstetric  case  continuously  runs.     (See  Introduction.) 

Pregnant  women  ought  to  feel  as  well  as  during  the  non-pregnant  state.  In  a 
large  percentage  of  the  cases  they  do,  or  even  feel  better,  but  often  this  is  not  so. 
They  are  more  irritable;  their  character  changes;  they  are  less  trustworthy;  they 
are  less  tidy;  they  have  various  aches  and  pains — neuralgia,  toothache,  headache — 
and  innumerable  symptoms,  which  the  doctor  is  called  upon  to  alleviate  during  the 
nine  months.  Sometimes  severe  mental  disturbances  arise.  Every  organ,  every 
tissue  of  the  body,  feels  the  stimulus  of  pregnancy.  The  whole  metabolism  is 
changed  to  meet  the  new  demands  on  the  system,  and  it  has  })een  well  said  that 
"Gestation  tests  the  integrity  of  every  structure  of  the  body"  (R.  Barnes).  If 
there  is  any  latent  disease  in  the  woman,  pregnancy  will  bring  it  to  the  surface. 
This  fact  warns  the  accoucheur  to  study  well  the  constitution  of  his  patient  and  to

The  Blood. — Investigators  are  not  agreed  on  the  changes  which  the  blood 
undergoes  during  pregnancy,  and  it  is  because  the  blood  reacts  differently  to  the 
stimulus  of  pregnancy  in  different  women.  Kiwisch  described  the  condition  of  the 
blood  in  early  pregnancy  as  a  "serous  plethora,"  or  hydremia.  From  external  ap- 
pearances many  women,  especially  those  generally  ill  nourished  or  living  in  poor 
circumstances,  suffer  from  a  condition  of  chloranemia. 

While  in  the  first  few  months  there  may  be  a  slight  reduction  in  the  reds  and 
increase  of  the  whites,  the  system  soon  reacts  to  the  necessities  imposed  by  preg- 
nancy, and  there  is  an  increase  of  the  reds,  also  of  the  whites,  the  latter  out  of  pro- 
portion to  the  reds — the  "physiologic  leukocytosis  of  pregnancy"  of  Yirchow. 
Blumenthal  found  a  leukocytosis  in  the  latter  months  of  pregnancy.  There  is  often 
an  increase  of  the  neutrophile  polynuclears  and  also  of  the  myelocytes,  the  latter 
indicating  the  part  taken  by  the  bone-marrow.  During  labor  there  is  a  marked 
leukocytosis,  especially  of  the  polynuclear  neutrophiles,  values  as  high  as  34,200 
being  obtained,  and  the  eosinophiles  disappear.  The  leukocj'tosis  was  more  marked 
in  cases  of  obstructed  labor.  In  the  main  these  findings  are  confirmed  ijy  the  recent 
work  of  Dietrich,  1911.  The  leukocytosis  is  more  marked  in  primiparse.  Of  the 
many  theories  as  to  its  cause,  that  of  Dietrich  seems  most  plausible,  that  it  is  a 
reaction  against  the  toxins  of  pregnancy. 

The  number  of  reds  at  first  remains  normal  or  is  slightly  increased,  and  there  is 
a  corresponding  increase  of  the  hemoglobin.  Later  the  reds  and  hemoglobin  are 
augmented.  The  alkalinity  of  the  blood  is  slightly  diminished,  but  the  freezing- 
point  remains  the  same  as  in  the  non-pregnant  state  —0.55  to  —0.59.  The 
amount  of  fibrin  and  fibrinogen  increases  from  the  sixth  month  of  ]iregnancy,  and 
may  be  one-third  greater  than  usual.  This  increase  of  lil)rin  is  i-»robabl>'  a  conserva- 
tive act  of  nature  to  prevent  dangerous  loss  of  blood  during  lal)or.  Perhaps  the 
hyperinosis  causes  the  thromboses  sometimes  observed  in  the  veins  of  the  leg  and 
pelvis  even  before  labor.  When  such  thromboses  give  rise  to  emboli,  sudden  death 
may  result.  Rebaudi  says  that  the  blood-platelets  increase  up  to  the  time  of  labor, 
being  1,500,000  per  c.mm.,  then  rapidly  decrease  to  000,000.     Their  agglutinatmg 


104  PHYSIOLOGY   OF   PREGNANCY 

properties  increase  with  the  number,  therefore  the  coagulating  power  of  blood  is 
greatest  just  before  labor. 

The  total  quantity  of  blood  is  augmented,  especially  in  the  last  months,  a  true 
plethora  existing  (Spiegelberg  and  Gsheidlen),  a  fact  recently  (1911)  again  proved 
by  Zuntz.  The  need  for  more  blood  must  be  admitted;  the  addition  of  the  fetus 
and  the  fetal  circulation,  the  development  of  the  uterine  arteries  and  veins,  the  en- 
largement of  the  veins  of  the  lower  extremities,  which  are  sometimes  so  great  that 
they  appear  to  be  veritable  caverns.  It  would  seem  that  they  act  as  reservoirs  and 
provide  for  the  loss  of  blood  at  labor.  Often  the  loss  of  a  quart  at  this  time  creates 
no  symptoms.  The  distended  veins  collapse  after  delivery.  Chauffard,  in  1911, 
found  an  increase  of  the  cholesterin  in  the  blood,  and  at  the  seventh  month  a  true 
cholesterinemia.  Aschoff  believes  this  may  explain  the  formation  of  gall-stones. 
Lipoids  in  the  blood  are  increased.  The  resistance  of  the  reds  to  hemolysis  by 
cobratoxin  is  diminished  (von  Graff,  1912).  The  Wassermann  reaction  becomes 
less  conclusive  during  pregnancy. 

The  blood-making  organs  show  marked  activity.  The  spleen  grows  from  140 
to  180  gm.  The  lumbar  glands  enlarge,  also  the  lymphoid  structures  of  the  endo- 
metrium. The  lymph-glands  all  over  the  body  are  frequently  enlarged  in  preg- 
nancy (Meyer).  The  thyroid  becomes  more  vascular,  often  hypertrophies.  The 
enlargement  is  noticed  after  the  sixth  month,  and  may  disappear  only  partly  after 
delivery.  Lange  claimed  that  the  thyroid  has  an  influence  on  pregnancy  and  espe- 
cial bearing  on  toxemia  and  eclampsia. 

The  ovary  activates  the  thyroid,  sometimes  to  the  point  of  producing  symptoms 
of  Basedow's  disease.  The  parathyroids  are  also  affected.  Compte,  in  1899,  first 
showed  that  the  hj^Dophysis  cerebri  hypertrophied  during  pregnancy,  a  fact  con- 
firmed by  Kohn  in  1910.  An  extract  of  the  pituitary  body,  administered  hypo- 
dermically,  stimulates  uterine  contractions.  Some  of  the  symptoms  and  changes 
in  pregnancy  are  acromegalic  in  nature,  e.  g.,  bones,  features,  hair,  larynx.  The 
interaction  of  the  internal  secretions  of  the  various  glands  is  not  at  all  well  under- 
stood, but  its  study  offers  a  promising  field  of  investigation.  Neu  (1911)  claims 
that  ''adrenalinemia"  exists  in  pregnancy. 

In  the  marrow  of  bones  decided  changes  have  been  noted.  Great  congestion 
and  even  a  transformation  of  fat  marrow  to  blood-forming  marrow  have  been  found. 
On  the  inside  of  the  skull,  along  the  middle  meningeal  artery  and  longitudinal  sinus, 
on  the  pelvic  bones,  and  occasionally  elsewhere,  one  may  find  thin  deposits  of  reddish 
bone  tissue.  They  are  1  to  2  mm.  thick,  and  each  pregnancy  brings  a  new  layer. 
Rokitanskj^  called  them  "puerperal  osteophytes,"  and  believed  they  had  some  work 
to  perform  in  the  blood  making  during  pregnancy.  They  occur  only  in  one-half  of 
the  cases  of  pregnancy  that  go  to  autopsy,  and  are  not  characteristic  because  they 
have  been  found  also  in  syphilis,  tuberculosis,  and  chronic  hydrocephalus. 

The  Circulatory  System. — The  changes  here  are  marked,  the  whole  cardio- 
vascular system  being  affected,  though  not  in  the  same  degree  as  v»^as  formerly 
believed.  Larcher,  in  1857,  described  an  eccentric  hypertrophy  of  the  heart,  es- 
pecially of  the  left  ventricle,  Blot  and  other  French  authors  agreeing  with  him.  A 
mass  of  literature  has  accumulated  on  the  subject.  Later  investigations  (Miiller 
and  Dreysel)  considering  the  weight  of  the  body  with  that  of  the  heart  have  shown 
that  there  is  only  a  slight  if  any  enlargement,  and  that  it  is  proportionate  to  the 
general  increase  of  the  body.  The  arguments  for  accepting  the  theory  of  hyper- 
trophy are,  first,  the  physiologic  need  for  more  work  by  the  heart;  the  increased 
amount  of  blood  to  be  moved ;  the  increased  viscosity  of  the  blood ;  the  addition  of 
the  large  area  of  blood-vessels  of  the  placental  circulation,  and  the  dilated  and  new 
blood-vessels  of  the  uterus;  the  increased  aljdominal  tension;  second,  the  results  of 
postmortem  measurements,  the  majority  of  authors  finding  some  increase  in  weight; 
third,  the  clinical  findings.     There  is  an  increase  in  the  area  of  cardiac  dulness,  but 


CHANGES    DUE   TO    PREGNANCY 


105 


Gerhardt  claims  this  is  duo  to  the  elevation  of  the  diaphragm  and  resulting  leveling 
of  the  heart.  Rontgcn-ray  examination  of  the  chest  in  ]ir('gnancy  (Kraus)  shows 
two  types — one  with  long  thorax,  a  convex  diaphragm,  and  undisturbed  heart, 
another  with  short  thorax,  raised  and  flattened  diaphragm,  and  heart  placed  hori- 
zontally. The  heart  in  all  cases  is  pressed  against  the  anterior  chest-wall,  displacing 
the  lungs;  thus  the  area  of  cardiac  dulness  is  enlarged. 

Many  pregnant  women  have  high  arterial  tension,  or  a  larger  or  more  freriuent 
pulse-beat,  but  there  is  nothing  in  the  pulse  of  pregnant  womcni  that  is  characteristic 
or  different  from  other  women  (Vejas).  Once  in  four  cases  one  hears  a  systolic 
murmur  over  the  base  of  the  heart,  not  transmitted  far,  and  not  always  accompanied

Drawn  from  a  photograph. 

by  accentuation  of  the  second  pulmonary  sound.  It  is  usually  hemic  in  origin,  but 
may  be  due  to  displacement  of  the  heart,  and  almost  always  disappears  shortly  after 
delivery.  One  must  be  slow  to  diagnose  heart  lesions  in  pregnancy,  but  it  is  gen- 
erally admitted  that  the  heart  is  peculiarly  liable  to  chsease  during  gestation,  and 
that  existing  disorders  are  aggravates  1. 

A  frequent  complaint  by  pregnant  women  is  of  fainting  spells.  There  are  also 
attacks  of  palpitation  with  a  sense  of  suffocation.  These  phenomena  are  usually 
due  to  a  disturbed  nervous  system,  hysteria,  tight  lacing,  a  full  stomach,  constipa- 
tion, or  the  toxemia  of  pregnancy. 

Pregnant  women  have  a  marked  tendency  to  develop  varicose  veins  of  the 
lower  half  of  the  body.     Nearly  every  one  has  at  least  one  or  more  phlebectasiae. 


106  PHYSIOLOGY   OF   PREGNANCY 

In  20  per  cent,  of  the  cases  the  varicosities  are  marked.  The  usual  sites  are  the 
legs,  the  vulva,  the  mons,  the  pelvis,  the  rectum,  the  anus,  the  vagina,  the  abdomen, 
the  buttocks,  in  the  order  named.  One  or  more  or  all  the  parts  maj'^  be  involved. 
One  leg,  usually  the  right,  may  exceed  the  other  in  the  size  and  number  of  the  vari- 
cosities. The  surface  veins  are  most  affected.  Of  causes,  several  are  given;  in- 
creased venous  congestion  below  the  diaphragm,  caused  by  the  greater  intra- 
abdominal tension  of  pregnancy;  obstruction  in  the  vena  iliaca  communis,  due  to  the 
rush  of  blood  from  the  enl  arged  vena  hypogastrica;  disturbed  vasomotor  conditions ; 
increase  in  the  total  amount  of  blood,  and  enlargement  of  the  veins  to  acconmiodate 
it;  congenital  anomaly  of  veins  brought  out  by  pregnancy ;  a  toxic  alteration  of  the 
vein-wall.  Predisposing  causes  are:  Thin-walled  veins,  heart  disease,  tight  girdles 
and  garters,  constipation,  carrying  heavy  loads,  frequent  pregnancies.  The  state 
of  pregnancy  undoubtedly  has  mainly  to  do  with  the  development  of  varices,  be- 
cause increased  abdominal  tension  may  exist  without  their  occurrence,  as  in  large 
ovarian  tumors,  ascites,  etc.  Parvin  tells  of  a  patient  who  knew  she  was  pregnant 
as  early  as  four  weeks  by  the  development  of  varicosities  in  the  legs.  Compression 
of  the  cava  by  the  uterus  does  not  cause  stasis  in  the  veins  below,  because  the  specific 
gravity  of  the  uterus  is  about  the  same  as  that  of  the  intestinal  mass.  After  the 
head  has  passed  into  the  pelvis  it  may  compress  the  internal  iliac  and  hypogastric 
veins,  but  one  does  not  often  observe  much  difference  from  this  unless  there  have 
been  marked  varicosities  previously. 

Edema  is  often  associated  with  varices  of  the  legs  and  has  the  same  causes.  It 
may  occur  alone,  and  may  have  other  causes.  Three  kinds  may  be  distinguished — 
the  mechanical,  due  to  the  obstructed  venous  circulation  in  the  abdomen,  which 
disappears  when  the  patient  rests  in  the  horizontal  position;  a  general  pufhness 
affecting  the  hands  and  face,  as  well  as  the  legs,  without  urinarj'  finchngs,  commoner 
in  hydremic  patients,  and  which  disappears  rapidly  after  labor;  a  true  anasarca, 
due  to  toxemia  or  nephritis,  and  always  significant  as  a  precursor  of  eclampsia. 
Possibly  the  latter  two  forms  are  allied.  The  edema  of  the  legs  may  be  enormous ; 
the  labia  majora  may  be  so  infiltrated  as  to  be  translucent  and  as  large  as  the  fist; 
the  sodden  abdominal  wall  may  hang  down  like  a  bag. 

The  lungs  are  displaced  by  the  growing  uterus.  They  retract  to  the  sides,  ex- 
posing more  of  the  heart.  The  thorax  is  lifted  up,  is  expanded  laterally,  and  slightly 
diminished  anteroposteriorly.  Part  of  this  change  is  permanent.  The  diaphragm 
is  pushed  up,  but  in  fat  subjects  its  upper  curve  is  not  convex,  but  flattened  or  even 
slightly  depressed  by  the  heart.  These  changes  are  more  marked  in  primiparse  than 
in  multiparae,  because  of  the  lax  abdominal  wall  in  the  latter.  The  respiration  is  more 
costal  than  abdominal,  because  of  the  restricted  excursion  of  the  diaphragm.  The  vital 
capacity  is  not  decreased,  but  the  respiration  is  more  frequeM — 24  to  26  a  minute. 
More  CO2  is  excreted.  (See  Vejas,  loc.  cit.)  When  lightening  occurs  at  the  end  of 
pregnancy,  the  chest  is  relieved.  Changes  which  some  rhinologists  consider  char- 
acteristic of  pregnancy  have  been  described  as  occurring  in  the  nose  and  throat. 
The  turbinates  are  turgid,  even  to  closure  of  the  nares  or  apposition  against  the 
septum.  Perhaps  these  findings  will  explain  the  deafness  and  ringing  in  the  ears 
some  pregnant  women  have,  or  even  some  of  the  so-called  neuroses  (Freund). 
There  seems  to  be  an  interrelation  between  the  nasal  cavities  and  the  genitalia 
(Fliess).  The  larynx  is  somewhat  congested,  especially  the  false  vocal  cords,  and 
there  is  some  slight  cellular  infiltration  of  the  tissue  (Hofbauer).  Brickner  believes 
otosclerosis  is  peculiarly  unfavorably  affected  by  pregnancy. 

The  Digestive  Tract. — One  of  the  first  symptoms  of  pregnancy  is  the  nausea 
and  vomiting — the  so-called  "morning  sickness."  It  may  be  present  as  early  as 
the  second  week,  but  usually  appears  about  the  fifth,  and  persists  until  the  twelfth 
week,  though  occasionally  it  continues  until  term.  The  patient  is  sick  at  the  stom- 
ach on  rising  or  after  breakfast,  and  vomits  the  meal  or  only  sour  mucus,  being  free 


CHANGES  DUE  TO  PREGNANCY  107 

from  nausea  the  rest  of  the  day.  The  feehng  is  similar  to  sea-sickness,  and  it  is 
aggravated  In-  sudden  motion.  The  vomiting  may  recur  at  the  end  of  pregnancy, 
after  "lightening,"  due  to  the  displacement  of  the  stomach  and  intestines,  bdt 
at  this  time  the  vomiting  may  also  be  due  to  toxemia,  and  mean  that  eclampsia 
threatens.  Should  the  nausea  and  vomiting  persist  the  greater  part  of  the  day,  the 
case  becomes  pathologic.  This  will  be  considered  under  the  subject  Hj-peremesis 
Gravidarum,  p.  343.  ^Morning  sickness  occurs  in  one-third  of  pregnant  women. 
Its  cause  is  obscure;  perliaps  it  is  a  reflex  from  the  uterus,  or  it  may  be  toxemic. 
Primiparae  are  oftener  affected  than  multiparse.  It  occurs  oftener  in  the  higher 
classes  of  society  and  in  the  neurotic. 

The  salivary  secretion  is  increased,  and  when  the  expectoration  is  frothy,  it  is 
called  "cotton  spitting."  In  some  cases  the  patient  is  actually  salivated;  then  the 
case  is  pathologic  and  needs  treatment.  The  teeth  easily  decay,  due  to  the  altera- 
tion of  the  secretions  of  the  mouth,  dentists  say,  but  perhaps,  too,  because  of  the 
demand  of  the  fetus  for  more  calcareous  salts,  or  the  teeth  partake  of  the  general 
changes  exhil^ited  by  the  bony  system.  Loosening  of  the  teeth  may  occur.  Gin- 
givitis to  a  mild  degree  is  also  observed,  but  this  borders  on  the  pathologic.  The 
taste  is  sometimes  perverted,  the  gra\ada  having  a  desire  for  unnatural  things,  as 
chalk,  slate-pencils,  sand,  salt,  etc.  This  sjTnptom  is  called  "pica,"  and  may  be- 
come morbid,  as  in  the  case  of  a  woman  who  craved  a  bite  of  her  husl)and's  arm,  and 
actually  took  it.  It  was  considered  dangerous  to  the  fetus  or  mother  to  oppose 
these  "cravings"  of  pregnant  women,  and  all  sorts  of  devices  were  employed  to  ap- 
pease them.  The  appetite  is  usually  increased  unless  nausea  occurs;  even  then, 
after  the  vomiting,  the  patient  is  hungry.  Some  women  have  a  voracious  appetite 
in  pregnancy,  and  often  satisfy  it  to  their  detriment,  in  the  belief,  fostered  by  many, 
that  they  are  eating  for  two.     Again,  anorexia  is  present  or  the  appetite  is  fickle. 

The  stomach  is  displaced  in  the  later  months  of  gestation,  being  forced  upward, 
backward,  and  to  the  left.  The  wall  is  congested,  and  pours  out  abundant  watery 
secretion.  The  hydrochloric  acid  is  increased,  causing  freciuent  "heartburn." 
Digestion  is  usually  more  active,  and  varies  ^^^th  the  appetite. 

The  liver  is  forced  upward,  backward,  and  to  the  right  in  the  late  months. 
Liver  dulness,  therefore,  must  be  corrected  in  this  period.  Tamier,  in  1857,  de- 
scribed a  fatty  infiltration  around  the  intralobular  veins,  but  this  is  not  constant, 
and  probably  does  not  occur  in  normal  pregnancy.  The  glycogen  in  the  liver  is 
decreased.  There  is  more  bile  present,  and  dilatation  of  the  bile-passages,  also 
ectasis  of  the  central  veins.  IMultinuclear  cells,  presumablj'  from  the  placenta, 
even  portions  of  \dlH,  are  sometimes  found  as  emboli  in  the  liver  vessels.  The  dis- 
turbance of  the  functions  of  the  liver  noted  by  some  authors  is  pathologic,  and  will 
be  considered  under  proper  headings. 

The  intestines  are  also  affected  by  pregnancy.  Constipation  is  almost  the  rule, 
being  due  to  the  displacement  of  the  bowels,  abnormal  innervation,  general  inac- 
tivity of  the  gra\dcla,  interference  by  the  uterine  tumor  wath  bearing-do^\Ti  efforts 
in  defecation.  Hemorrhoids  are  common,  from  the  constipation  and  the  increase 
of  venous  pressure  below  the  diaphragm. 

General  Metabolism. — The  body  weight  increases  in  the  last  three  months, 
according  to  Hecker  and  Gassner:  seventh  month,  2400  gm.;  eighth  month,  1690 
gm.;  ninth  month,  1540  gm.  This  varies  in  relation  to  the  size  of  the  person, 
multiparse  showing  larger  gains  than  primiparse.  The  increase  in  weight  is  due  to — 
(1)  The  fetus  and  secundines;  (2)  increased  assimilation;  (3)  storing  up  of  fat  and 
albumin;  (4)  accumulation  of  water,  especially  in  the  lower  extremities;  (5)  increase 
of  the  amount  of  blood.  A  store  of  potential  energy-  is  laid  up  for  conversion  into 
heat  and  force  during  labor,  and  milk  during  lactation.  The  hips  round  off  and 
become  broad;  the  breasts  have  more  fat.  A  gravida  gains  one-thirteenth  of  her 
body  weight  during  pregnancy.     If  the  fetus  dies,  this  gain  does  not  occur  or  the 


108  PHYSIOLOGY    OF    PREGXAXCY 

patient  may  lose  weight,  and  this  fact  may  be  used  in  the  diagnosis  of  the  death  of 
the  infant. 

The  metaboHsm  in  pregnancy  has  been  studied  ])y  von  Winckel,  IMiotti,  and 
Hahl,  but  httle  is  definitely  known.  The  nitrogen  output  is  decreased,  all)umin 
being  stored  up.  Fat  and  iron  are  also  stored  up.  Carbohydrates  are  rapidly 
transformed,  and  before  labor  carbonic  acid  is  excreted  in  large  amounts. 

]\Iost  women  feel  ])etter  during  pregnancy  than  at  other  times,  but  in  some, 
especially  the  anemic  and  the  neurotic,  a  condition  of  asthenia  develops  in  the  early 
months.  Later  the  nutrition  is  better,  and  the  woman  may  enjoy  a  permanent 
improvement  in  health  from  the  stimulus  of  pregnancy.  On  the  other  hand,  some 
women  suffer  a  permanent  neurasthenia  from  the  strain  of  reproduction. 

The  Urine. — The  quantity  is  usually  increased  about  one-fourth.  This  poly- 
uria explains  in  part  the  frequent  urination  of  pregnant  women.  The  specific 
gravity  is  low,  total  solids  and  urea  output  being  the  same  as  or  slightly  less  than  in 
the  non-pregnant  state.  The  sulphates  and  phosphates  do  not  change;  the  chlorids 
decrease  in  the  last  months.  Albumin  is  found  in  one-third  of  the  cases  of  preg- 
nancy, if  one  uses  the  finest  tests,  as  acetic  acid  and  ferrocyanid  of  potash.  The 
frequency  and  amount  increase  until  labor,  when  fully  50  per  cent,  of  cases  show 
albuminuria.  These  figures  are  from  the"  Han  dbuchderGeburtshilfe,"  vol.  i,  p.  391. 
If  one  uses  the  hot  and  cold  nitric-acid  tests,  which,  for  practical  purposes,  are  suffi- 
cient, one  will  find  al])umin  in  only  3  to  5  per  cent,  of  gravidse  and  30  per  cent,  of 
parturients.  Jaeger  found  albumin  in  70  per  cent,  of  pregnant  women,  and  believes 
it  to  be  frequently  of  lordotic  origin,  or  due  to  a  latent  bacterial  influence.  Many 
times  the  albumin  comes  from  the  urinary  tract  or  from  the  external  genitals.  Renal 
albuminuria,  in  the  experience  of  the  author,  is  rare  in  pregnancy,  and  should  always 
be  looked  on  with  suspicion.  ]\Iild  catarrhs  of  the  bladder,  pyelitis,  and  ureteritis 
are  not  uncommon  in  pregnant  women.  The  highly  congested,  edematous  bladder 
may  permit  the  escape  of  albumin  into  the  urine.  The  role  of  the  ''kidney  of  preg- 
nancy" in  the  production  of  albuminuria  will  be  discussed  under  Toxemia  and 
Eclampsia,  in  the  Pathology  of  Pregnane}',  since  the  author  believes  the  phenomenon 
is  not  normal. 

Sugar  is  occasionally  found  in  the  urine  during  gestation,  and  is  of  two  kinds — 
lactose  and  dextrose.  Lactosuria  occurs  in  16  per  cent,  of  gravidse  (Ney),  is  more 
pronounced  near  labor,  most  pronounced  in  the  first  week  of  the  puerperium  (77 
per  cent.),  and  disappears  after  lactation  is  discontinued,  though  it  may  be  tem- 
porarily augmented  by  the  weaning  process.  It  is  due  to  absorption  of  milk-sugar 
from  the  functionating  breasts,  and  is  not  an  unfavorable  sign,  unless  it  is  large  in 
amount  and  attended  by  signs  of  disturbed  nutrition.  (See  Literature.)  True 
glycosuria,  on  the  other  hand,  is  more  significant,  though  some  authors  describe  a 
''physiologic  diabetes  of  pregnancy."  Alimentary  glycosuria  is  more  likely  to 
occur  during  gestation,  because  of  the  decreased  glycogenic  function  of  the  liver  or 
the  diminished  assimilating  power  for  sugar,  and  one  finds  0.01  per  cent,  of  grape- 
sugar  occasionally,  as  one  does  in  men,  but  with  the  ordinary  tests  employed  by  the 
practitioner  sugar  is  not  regularly  found  in  normal  gravidse.  Its  occurrence  is 
alwaj'S  a  matter  of  grave  concern.  (See  Diabetes  in  Pregnancy,  p.  502.)  Acetone 
in  the  minute  quantities  usually  found  in  women  is  also  determinable  during  preg- 
nancy. It  is  increased  in  amount  during  hard  labor,  during  the  first  days  of  the 
puerperium,  febrile  conditions,  toxemia  and  eclampsia,  syphilis,  ectopic  gestation, 
and  death  of  the  fetus,  but  is  not  pathognomonic  of  this.  Peptone,  according  to 
Fischel,  occurs  in  25  per  cent,  of  gravidse  and  96  per  cent,  of  puerperse.  It  probably 
comes  from  the  absorption  of  the  fatty  degenerated  uterine  tissue  during  involution, 
and  has  no  proved  bearing  on  the  metabolism  of  the  fetus,  the  lochial  discharge,  or 
the  fermentation  processes  of  the  intestine.  It  occurs  in  sepsis,  acute  yellow  atrophy 
of  the  liver,  toxemia,  and  eclampsia.     Bar  claims  that  the  urine  shows  increased

The  Bones.— Reference  has  been  made  to  the  thin,  porous,  soft  bony  deposits 
on  tlie  inner  surface  of  the  cranium— the  puerperal  osteophytes.  Their  function  is 
unknown;  probal)lv  they  have  to  do  with  the  blood  changes  of  pregnancy,  but  it 
has  been  suggested  that  they  have  a  relation  to  the  bony  formation  of  the  fetus.

The  bones  in  pregnancv  show  increased  vascularity,  especially  the  reel  marrow, 
and  to  a  certain  extent  resemble  the  changes  found  in  osteomalacia  Indeed,  a 
phvsiologic  osteomalacia  of  pregnancy  has  been  described  (Hanau).  i^ractures 
unite  well  in  pregnancv,  contrary  to  an  old  notion.  The  joints  of  the  pelvis  soften, 
as  has  been  mentioned  (p.  98).  In  several  cases  of  young  women  the  author  has 
observed  a  rapid  gro^^'th  of  the  pelvic  bones  during  pregnancy,  mcreasing  materially 
the  capacity  of  the  pelvis. 


110  PHYSIOLOGY    OF   PREGNANCY 

The  spinal  column  is  straightened,  the  uterine  tumor,  prominent  in  front, 
changes  the  line  of  direction  of  the  woman's  person.  This  line  of  direction  tends  to 
fall  anterior  to  her  base  of  support.  Therefore  she  throws  her  shoulders  back  and 
straightens  her  neck  and  head.  The  curve  in  the  small  of  the  back  is  exaggerated 
(Figs.  133  and  134),  the  pelvis  being  rotated  slightly  on  the  femora.  These  changes  in 
the  skeletal  dynamics  give  the  patient  a  peculiar  attitude  and  gait  or  strut,  which 
Shakspere  called  the ''pride  of  pregnancy."  With  marked  softening  of  the  pelvic 
joints,  however,  the  patient  has  a  waddling  gait,  l:)ecause  the  innominates  move  on 
each  other.  In  cases  of  pendulous  abdomen  and  with  twins  the  changes  in  the 
attitude  of  the  gravida  are  exaggerated.     (See  La  Pointe.) 

The  skin  is  much  affected  Ijy  pregnancy.  Pigment  is  deposited  in  more  or  less 
tj'pical  regions — the  nipples,  the  vulva,  the  linea  alba,  the  navel,  the  face.     The

pigmentation  of  the  linea  alba  changing  it  to  a  linea  nigra,  of  the  nipples  already 
considered  and  of  the  face  is  most  connnon.  The  forehead,  cheek,  and  nose  are 
covered  with  brown  stains  which  cannot  be  wiped  off.  They,  when  marked,  ap- 
pear like  a  mask,  and  the  condition  has  been  called  "the  mask  of  pregnancy"  (Fig. 
135).  This  deposit  of  pigment  in  the  rete  cutis  occurs  oftener  in  nervous  women 
or  those  suffering  from  uterine  disease.  Occurring  outside  of  pregnancy,  it  is  called 
chloasma  uterinum.  Brunets  are  more  affected  than  blonds.  Women  of  careless 
personal  habits  are  more  prone  to  manifest  this  sign,  lack  of  attention  to  skin  and 
bowels  being  a  factor.  The  actual  cause  of  the  deposits  is  unknown — slow  circula- 
tion in  the  capillaries,  especially  at  the  junction  of  the  embryonal  folds,  hypertrophy 
of  the  suprarenals,  active  destruction  of  the  red  blood-corpuscles,  abnormal  iron 
metabolism,  hepatic  disturbances,  and  neurotic  influences  having  all  been  invoked. 


CHANGES  DUE  TO  PREGNANCY  HI 

According  to  Samuely,  tho  pigmentation  is  due  to  the  action  of  a  ferment,  tyro- 
sinase, on  the  tyrosin  in  th(^  blood  during  exposure  to  sunlight.  Both  the  Blazek 
twins  were  pigmented,  though  only  one  was  pregnant.  A  peculiar  darkening  of 
the  eyelids  has  also  been  noted  in  pregnancy.  It  may  be  due  to  congestion  or  pig- 
ment. This  pigmentation  disappears  mostly  after  labor,  and  especially  when  the 
menses  are  established,  but  some  of  it  may  persist  for  years.  The  vasomotor  con- 
trol of  the  cutaneous  vessels  is  disturbed  during  pregnancy;  thus  one  is  able  to  pro- 
duce red  lines  by  simply  drawing  the  finger  over  the  surface. 

The  sweat  and  sebaceous  glands  increase  in  activity,  requiring  more  care  of  the 
patient  to  prevent  odors.  In  untidy  women  pityriasis  versicolor  is  more  likely  to 
develop.  The  hair  takes  on  increased  growth;  sometimes  a  fine  lanugo  appears 
on  the  face  and  chest.  This  falls  out  later.  The  nails  are  thinner.  The  subcuta- 
neous fat  becomes  thicker,  the  finer  features  of  the  face  coarser;  the  complexion  in 
the  early  months  is  sallow,  in  the  later  months  florid.  Diseases  of  the  skin  are  very 
common  during  pregnancy. 

The  Nervous  System. — Pregnant  women  are  more  impressionable,  subject  to 
varying  moods,  are  hyperexcitable,  and  sometimes  a  change  in  their  character  occurs, 
a  quiet,  sweet-tempered  person  becoming  querulous  and  irritable,  or  vice  versa.  The 
author  has  only  seldom  observed  such  changes  in  any  degree.  In  olden  times  preg- 
nant women  were  considered  morally  irresponsible,  and  the  condition  was  advanced 
in  extenuation  of  crime.  They  are  not  reliable  witnesses,  perception  being  not  so 
acute  and  interpretation  false.  A  tendency  to  melancholia  occasionally  develops, 
and  real  psychoses  are  not  uncommon,  especially  if  there  is  a  family  taint.  These 
symptoms  may  be  the  expression  of  a  toxemia,  as  also  may  be  neuralgias  (espe- 
cially facial,  sciatic,  and  dental),  the  tingling  and  numbness  in  the  extremities, 
headache,  and  disturbances  of  the  special  senses— hemeralopia,  amaurosis,  tinnitus. 
The  exaggerated  reflex  excitability  of  the  nervous  system  is  manifested  by  marked 
skin  and  tendon  reflexes,  even  ankle^clonus,  and  by  visceral  reflexes,  vomiting, 
indigestion.  In  the  early  months  a  tendency  to  sleep,  especially  after  meals,  is 
often  noticed,  and  some  women  use  this  symptom  to  diagnose  the  pregnancy. 
Hysteric  women  suffer  an  exaggeration  of  their  symptoms,  and  in  them  accesses 
of  grand  hysteria  are  more  common. 

A  sort  of  fainting  spell  is  a  frequent  complaint  of  pregnant  women.  It  is  ac- 
companied by  palpitation  or  fluttering  of  the  heart,  sometimes  with  pallor,  and 
occasionally  by  slight  loss  of  consciousness,  resembling  petit  mal.  Unless  due 
to  organic  cardiac  disease,  the  symptom,  though  annoying,  is  not  dangerous.

CHAPTER  V 
THE  LENGTH  OF  PREGNANCY 

It  is  impossible  to  determine  the  time  of  conception,  as  was  shown  on  p.  26, 
even  Avhen  the  date  of  the  fruitful  coition  is  certain.  Labor  occurs  often  as  the 
result  of  some  trauma — a  fright  or  any  disturbance  of  the  woman's  ordinary  course 
of  life.  Since  the  beginning  and  the  end  of  pregnancy  are  indeterminable,  of  course 
we  cannot  estimate  the  exact  length  of  the  period.  As  a  datum  for  the  reckoning 
the  menses  are  absolutely  unreliable,  since  a  woman  may  menstruate  during  the 
first  months  of  pregnancy,  in  which  case  it  would  seem  that  she  bore  a  fully  de- 
veloped infant  after  a  short  gestation,  and,  on  the  other  hand,  a  woman  may  con- 
ceive during  a  period  of  amenorrhea,  thus  giving  the  impression  that  pregnancy  was 
prolonged  to  ten  or  even  eleven  calendar  months.  This  will  explain  those  cases, 
referred  to  in  most  text-books,  of  pregnancy  lasting  three  hundred  and  eighty  to 
four  hundred  days.     (See  Parvin,  Obstetrics,  p.  210.) 

The  most  reliable  datum  from  which  to  estimate  the  beginning  is  the  date  of 
fruitful  coition,  and,  reckoning  from  this  day,  pregnancy  has  been  found  to  vary 
from  two  hundred  and  twenty  to  three  hundred  and  thirty  days,  the  average  being 
two  hundred  and  seventy  days.  In  cows  the  average  length  of  pregnancy  is  two 
hundred  and  eighty-five  days,  but  a  fully  developed  calf  may  be  delivered  any  time 
from  two  hundred  and  forty-one  to  three  hundred  and  twenty-one  days  after  the 
cow  was  covered  (Ahlfeld).  From  time  immemorial  women  have  reckoned  two 
hundred  and  eighty  days,  ten  lunar  months,  or  nine  calendar  months,  from  the  first 
day  of  the  last  period  as  the  length  of  normal  gestation,  and  for  practical  purposes 
this  may  be  accepted,  because  in  the  majority  of  cases  it  holds  true,  but  one  must 
remember  and  admit  the  exceptions.  No  doubt  some  children  require  a  longer 
time  in  the  uterus  for  full  development  than  others.  Some  seeds  in  favorable  soil 
grow  faster  than  others.  The  ^vriter  has  delivered  children  that  were  carried  eight 
months  that  were  as  fully  matured  as  full-term  infants,  and  also  in  one  case,  figiiring 
as  accurately  as  is  ever  possible,  he  delivered  a  child  weighing  three  and  one-half 
pounds  which  was  fully  three  weeks  over  term. 

The  German  laAV  recognizes  the  legitimacy  of  a  child  born  three  hundred  and 
two  days  after  the  death  of  the  husband;  the  French  law,  three  hundred,  and  in 
America,  while  there  is  no  legal  limit,  three  hundred  and  seventeen  clays  was  judi- 
cially allowed  (Schatz).  The  reader  desiring  authorities  in  medicolegal  cases  of 
this  kind  should  consult  v.  Winckel  (ioc.  cit.). 

Without  doubt  pregnancy  may  be  prolonged  and  an  overg^o■v\^l  child  delivered. 
Von  Winckel  found  that  in  2.2  per  cent,  of  children  weighing  more  than  4000  gm. 
(8^  pounds)  the  pregnancy  had  lasted  more  than  three  hundred  and  two  days. 
Ciulla  found  that  in  1  case  of  200  the  pregnancy  lasted  more  than  three  hundred  and 
twenty  days.  Children  that  are  carried  over  term  may  be  larger  in  all  dimensions, 
or  they  may  grow  longer  and  harder  (Bossi).  The  cranial  bones  ossify,  the  bi- 
parietal  chameter  increases,  the  body  becomes  firmer  and  less  pliable;  thus  in  both 
instances  delivery  is  rendered  difficult  and  more  dangerous  to  mother  and  child. 
Children  that  are  being  carried  over  time  not  seldom  die  before  labor.  A  careful 
autops}^  performed  in  a  case  of  this  kind  showed  no  pathologic  changes  except  granu- 
lar degeneration  of  the  epithelium  of  the  kidneys.  In  some  instances  labor  pains 
come  on  at  the  computed  term  of  pregnancv,  but  they  subside  and  a  period  of  three 

112' 


THE  LENGTH  OF  PREGNANCY  113 

or  four  weeks  elapses  until  actual  delivery  occurs.  The  author  considers  it  inad- 
visable to  allow  a  woman  to  continue  far  beyond  the  normal  date  of  term,  and,  in 
the  interest  of  both  child  and  mother,  induces  labor  in  such  cases.  '']\lissed 
labor"  is  a  term  introduced  by  Oldham  to  describe  cases  where  pains  come 
on  when  expected,  but  cease,  the  child  dies,  and  is  carried  in  the  uterus  a  greater  or 
shorter  time,  as,  in  one  case,  eleven  months.  A  dead  ovum  carried  in  the  uterus  is 
not  pregnancy.  Various  factors  may  influence  the  length  of  gestation,  as  the  age  of 
the  woman,  the  sex  of  the  child,  etc.  Young  women  are  likely  to  have  a  shorter 
gestation ;  older  women,  longer.  Women  who  have  been  sterile  for  years  and  old 
primipane  are  likely  to  go  over  term.  AVomen  who  have  delayed  puberty,  dys- 
menorrhea, who  have  long  hard  rigid  cervices,  are  also  likely  to  have  delayed  labor. 
Primiparae,  except  old  ones,  not  seldom  fall  into  labor  a  few  weeks  before  the  date 
set,  the  tense  abdominal  wall  forcing  the  head  into  the  pelvis  against  the  cervix, 
which  evokes  pains.  Subsecjuent  children  are  carried  longer,  until  the  sixth  or 
eighth,  when  the  uterus,  because  of  lack  of  tonus  or  of  pathologic  changes,  expels  the 
product  of  conception  as  soon  as  it  is  ripe.  ]\Iales  are  said  to  be  carried  longer  than 
females.  While  this  is  true  in  animals,  the  author  cannot  confirm  it  from  his  ovm 
experience.  Women  who  are  active  in  the  last  months  of  pregnane^'  are  less  likely 
to  go  over  term  than  the  lazy  ones,  who  take  no  exercise.  One  notices  this  in  hos- 
pital practice.  There  is  a  popular  notion  that  a  gravida  should  exercise  much  dur- 
ing gestation  or  "the  baby  will  be  gro^sTi  to  her  side,"  meaning  that  she  will  have  a 
difficult  labor  from  overgrowth  of  the  infant.  In  summer  women  are  likely  to  give 
birth  earlier  than  in  winter.  Heredity  seems  to  play  a  role.  De  la  Motte  reports 
the  case  of  a  woman  who  had  two  children  at  the  seventh  month.  These  girls  grew 
up,  married,  and  had  children  at  seven  months.  Retzius  describes  an  instance  of  a 
mother  and  her  two  daughters  in  all  of  whom  pregnancy  was  much  prolonged. 

Precocious  and  Late  Pregnancy. — The  earliest  authentic  pregnancy  is  reported 
b}'  Bodd.  The  girl  was  eight  years  and  ten  months  old,  and  delivered  a  child  weigh- 
ing 3500  gm.  (about  73^  pounds),  which  had  hair  on  the  pubis.  Pregnancy  in  girls 
of  twelve  to  fifteen  is  not  rare,  and  experience  shows  that  most  of  the  children  live 
and  that  labor  is  not  always  difficult.  The  pelvis  develops  rapidly  during  preg- 
nancy, and  the  child  is  usually  small,  with  a  soft  head,  which  accounts  for  the  un- 
expected safety  of  these  precocious  labors.  The  latest  pregnancy  on  record  is  the 
one  reported  by  Kennedy.  The  woman  was  sixty-two  years  old,  and  this  was  her 
twenty-second  labor.  The  author  delivered  a  woman  of  fifty-two  years  safely  of  a 
living  infant  weighing  over  seven  pounds.  In  some  of  the  cases  reported  (Strass- 
man)  menstruation  had  been  absent  for  years.

SECTION  II 

PHYSIOLOGY  OF  LABOR 


CHAPTER  \1 
DEFINITION— CAUSES— CLINICAL  COURSE 

Labor  is  a  function  of  the  female  organism  by  which  the  product  of  conception 
is  expelled  from  the  uterus  through  the  vagina  into  the  outside  world,  the  regressive 
metamorphosis  of  the  genitals  started,  and  the  secretion  of  milk  inaugurated.  There 
are  three  essential  points  in  the  definition,  which  excludes  the  extraction  of  the  fetus 
by  any  other  passage,  as  in  cesarean  section.  Synonyms  for  labor  are  delivery, 
parturition,  travail,  childbirth,  accouchement,  confinement. 

Abortion  is  the  interruption  of  pregnancy  before  the  fetus  is  viable,  i.  e.,  capable 
of  extra-uterine  existence,  which  is  after  the  twenty-sixth  week. 

Premature  labor  is  the  interruption  of  pregnancy  after  the  fetus  is  viable,  but 
before  term,  i.  e.,  the  normal  end  of  gestation. 

Miscarriage  is  an  expression  used  by  the  laity  to  signify  the  occurrence  of  a 
premature  interruption  of  the  pregnancy  at  any  time. 

Labor  should  be  a  normal  function  of  the  human  female.  It  is  so  intricate, 
however,  that  a  great  many  irregularities  may  mark  its  course.  The  unhygienic 
surroundings  in  which  women  live,  prior  diseases,  the  tendency  to  laziness,  the  evils 
of  dress,  of  living,  occupation,  heredity,  chronic  endometritis,  salpingitis,  the  evolu- 
tion of  the  head,  i.  e.,  increased  size  of  the  child's  cranium,  due  to  the  increased 
mental  capacities  of  the  race,  all  tend  to  produce  conditions  which  influence  the 
course  of  labor  and  may  make  it  absolutely  impossiljle  in  a  given  case,  or  fraught 
with  great,  even  fatal,  danger. 

We,  therefore,  must  divide  cases  into  two  groups: 

1.  Normal  labor,  or  eutocia. 

2.  Abnormal  (pathologic)  labor,  or  dystocia. 

As  a  matter  of  fact,  a  really  normal  labor  without  the  slightest  irregularity  is 
rare;  almost  always  there  is  some  small  point  that  is  peculiar,  although  it  may  not 
affect  the  course  of  the  lal^or,  and  the  case  may  end  favorably  for  mother  and  child. 
In  general  we  call  those  cases  normal  where  we  do  not  have  to  interfere — where  the 
woman  expels  the  child  and  placenta  herself,  and  she  and  the  child  live.  Strictly 
speaking,  however,  unless  the  woman's  condition  is  exactly  as  good  as  it  was  before 
conception  and  the  child  perfectly  well  and  uninjured,  the  labor  may  not  be  called 
normal.  Such  cases  as  these  are  excessively  rare.  The  boundaries  between  eutocia 
and  dystocia  are  very  narrow,  and  depend  largely  on  the  individual  views  of  the 
obstetrician.  Certain  complications  are  classed  by  some  under  eutocia,  while  by 
others  they  are  called  distinctly  pathologic.  For  example,  I  consider  the  vomiting 
of  pregnancy,  the  kidney  of  pregnancy,  breech  and  face  presentation,  rupture  of 
the  urogenital  septum,  to  be  pathologic  conditions,  while  many  authors  hold  them 
to  be  normal. 

In  the  study  of  the  phenomena  of  parturition  four  factors  must  be  considered : 
(1)  The  powers,  by  which  the  expulsion  of  the  ovum  is  accomplished;   (2)  the  pas-

sages,  which  represent  the  road  and  the  resistances  met;  (3)  the  passengers,  the  child 
and  its  adnexse  (placenta,  etc.);  and  (4)  external  compUcations  which  may  disturb 
the  course  of  the  function.  The  last-named  factor  is  the  pathologic  one,  and  will 
be  omitted  for  the  present.  The  other  tliree  factors  make  uj)  the  study  of  the 
mechanism  of  labor. 

The  Causes  of  Labor. — What  brings  on  labor?  Why  should  the  uterus  which 
has  carried  the  ovum  for  so  many  months,  suddenly  violently  expel  it?  Nature 
certainly  recognizes  the  right  moment  for  the  expulsion,  since  it  is  almost  always 
accomplished  at  a  time  when  the  child  is  best  able  to  carry  on  extra-uterine  existence, 
and  before  it  has  become  too  large  to  pass  safely  through  the  parturient  canal. 
What  the  cause  is  that  sets  the  uterus  in  action  has  been  the  subject  of  much  specula- 
tion and  investigation,  but  nature  still  hides  the  secret.  We  wish  to  know  it,  be- 
cause often  it  is  necessary  to  bring  on  labor  ourselves,  and  experience  has  shown  that 
it  is  wise  to  follow  nature's  methods  in  accomplishing  things.  The  many  theories 
can  only  be  touched  upon. 

1.  The  ovum  is  prepared  for  separation  by  the  degeneration  of  the  decidua  in  the  later 
months  of  pregnancy,  and  the  disappearance  of  the  phicental  septa-,  thus  loosening  the  attachment 
of  the  hvtter  to  the  uterine  waU.  The  ovum,  then,  according  to  Simpson,  Huve,  and  Scanzoni, 
becomes  a  foreign  bod}'.  The  phxcenta  does  not  loosen  its  hving  attachment  to  the  uterine  wall 
until  the  child  is  delivered,  therefore  this  theory  is  untenable. 

2.  Throml)osis  in  the  placental  vessels  causing  increase  of  the  carbon  dioxid  content  of  the 
uterine  blood  has  been  advanced  by  Leopold.  The  thrombosis  is  not  constant,  and  it  too  must  be 
explained. 

3.  BrowTi-Sequard  proved  that  an  increase  of  carbon  dioxid  in  the  blood  will  evoke  uterine 
contractions.  Lack  of  oxygen  ^411  do  the  same.  The  increased  venosity  of  the  fetal  blood,  which 
normally  occurs  in  the  later  months,  due  to  the  narrowing  of  the  ductus  Arantii  and  ductus  Botalli, 
has  also  been  suggested  as  provocative  of  uterine  action — all  not  proved,  but  they  indicate  chemic 
lines  of  study  instead  of  mechanical. 

•4.  Products  of  altered  metabolic  activity  of  the  mother  or  from  the  child,  accumulating  in 
the  maternal  blood,  may  evoke  the  pains,  either  by  way  of  the  uterine  innervation  or  indirectly 
through  the  vasomotor  system.  Schaeffer  believes  that  the  sjTicytium  has  an  influence  in  limiting 
the  passage  of  poisons  from  the  fetus  to  the  mother.  Late  in  pregnancy  the  action  of  the  s^-ncytium 
is  insufficient.  Others  have  referred  to  the  possibiUty  of  fetal  poisons  stimulating  the  uterine 
muscle.  WilUams  found  that  just  before  labor  there  was  diminished  nitrogen  output  in  the  urine, 
with  marked  diuresis,  confirming  the  suspicion  that  metabolic  changes  are  involved  in  the  causation 
of  labor.  It  is  possible  that,  by  working  this  field,  the  active  factor  may  be  discovered.  We  know 
that  diphtheria  antitoxin  sometimes  brings  on  abortion. 

5.  Mauriceau  believed  that  the  excessive  distention  of  the  uterine  wall  resulted  in  labor. 
The  uterine  wah  Is  not  distended  at  term,  therefore  only  in  pathologic  cases,  as  twins, — polyhy- 
dramnion, — could  such  a  force  act. 

6.  The  increased  irritability  of  the  uterus  is  generalh^  acknowledged  to  be  an  important 
factor.  "We  know  that  the  uterus  contracts  from  the  beginning  of  pregnancy,  and  also  that  the 
contractions  become  stronger  and  more  easily  elicited  toward  the  end.  This  marked  irritability 
is  due  to  the  great  increase  in  the  development  of  the  muscular  fibers  and  the  nerves  and  cells  of 
the  cervical  ganglion.  When  the  end  of  pregnancy  is  near,  some  slight  accident  may  make  the 
contractions  stronger,  and  each  contraction  stimulates  the  succeeding  one  until  regularity  is 
estabUshed. 

7.  The  influence  of  the  periodicity  of  menstruation  cannot  be  denied,  though  why  the  final 
effort  of  the  uterus  should  come  at  the  completion  of  the  ten  menstrual  cycles  is  not  understood. 
It  is  not  believed  that  the  ovaries  have  anything  to  do  with  it,  since  labor  can  occur  without  them. 
The  same  is  true  of  the  corpus  luteum,  though  Born  and  Friinkel  have  sought  to  connect  the  two. 
In  some  women,  particularly  those  of  a  nervous  tj^pe,  there  occur,  during  pregnancy,  at  the  time 
of  the  usual  menses,  pecuhar  sensations  and  manifestations  which  show  that  some  influences  are 
at  work.  Neuralgic  pains,  especially  in  the  sacrolumbar  region,  insomnia,  skin  eruptions,  increase 
of  the  varicosities,  vomiting,  nausea,  diarrhea,  constipation,  decreased  urine,  sometimes  albumin, 
uterine  pain,  sometimes  small  hemorrhages,  and  the  tendency  to  abort  are  greater  at  these  periods. 
G.  de  PaoU  studied  these  changes  in  30  women,  and  found  diminished  lung  capacity;  lower  blood- 
pressure;  increased  sensibility  of  the  skin  and  of  the  reflexes;  more  rapid  pulse.  Pathologic  con- 
ditions are  more  common  at  these  periods — for  instance,  eclampsia,  fainting,  hysteria,  pains  in  the 
bones. 

8.  Pressure  of  the  presenting  part  on  the  lower  uterine  segment  on  the  cervix  and  the  nerves 
of  the  great  cervical  and  retrocervical  ganglia,  and  other  plexuses  around  the  cervix  and  upper 
vagina,  is  an  old  (Galen,  Power)  and  favorite  theory,  but  it  will  not  explain  all  cases,  such  as  breech 
and  transverse  presentation  and  the  uterine  contractions  of  extra-uterine  pregnancy.  In  some  cases 
the  head  may  be  deep  in  the  pelvis,  and  pressing  hard  on  the  cervix,  without  evoking  pains.  Still, 
chnical  experience  shows  that  when  the  child  settles  well  into  the  lower  uterine  segment  the  dila- 
tation of  the  cervix  begins,  and  laljor  comes  on.  The  methods  employed  in  inducing  labor  nearly 
all  operate  by  irritations  applied  to  the  nerves  of  this  region,  e.  g.,  the  packing  of  the  cervix  with 


116  PHYSIOLOGY   OF   LABOR 

gauze,  the  application  of  colpeurynters,  bougies,  etc.  One  can  often  bring  on  lal:)or  bj-  passing  the 
finger  around  the  internal  os  and  stretching  it  a  little. 

These  are  the  principal  theories,  of  which  the  most  plausible  are  pressure  of  the  presenting 
part  on  the  gangUa  and  nerves  of  the  lower  uterus  and  cervix,  the  increased  irritabilitj-  of  the  uterus, 
and  changes  in  the  blood  of  the  mother,  fetal  in  origin. 

9.  The  importance  of  accident,  however,  must  not  be  overlooked.  "NMien  everything  is 
ready  for  labor,  the  parts  softened,  the  cervix  begun  to  imfold,  the  uterine  muscle  well  developed 
and  having  attained  a  high  degree  of  irritabiUty,  it  is  easy  to  see  how  some  slight  cause,  mechanical 
or  emotional,  may  suddenly  start  the  uterine  contractions.  As  soon  as  one  contraction  has  oc- 
curred it  seems  to  form  the  irritant  for  another,  or  forces  the  o\aim  against  the  cer\'ix,  stimulating 
the  nerves,  so  abundant  here,  and  thus  labor  is  put  in  progress.  Such  exciting  causes  are  physical 
shocks, — jolts,  running  up  or  down  stairs,  coitus,  diarrhea,  straining  at  stool — mental  shocks, — 
sudden  fright  or  joy,— of  which  there  are  numerous  illustrious  examples.  The  Bible  tells  us  that 
the  wife  of  Phineas,  upon  hearing  that  her  husband  was  killed  in  battle,  went  into  labor.  A 
patient  of  the  author's,  feeling  that  her  labor  was  due,  walked  down  and  up  the  six  flights  of  stairs 
to  her  hotel  apartment.  Pains  came  on  within  a  few  hours.  She  had  a  slight  hemorrhage  behind 
the  placenta.     A  dose  of  castor  oil  or  quinin  will  often  bring  on  labor  at  term. 

!Most  recenth',  the  onset  of  labor  has  been  ascribed  to  an  anaphylactic  process. 
In  1905  I  began  a  series  of  experiments,  seeking  to  prove  that  ferments  circulating 
in  the  blood  of  parturient  horses  could  invoke  labor  in  pregnant  guinea-pigs,  but 
was  unable  to  prosecute  the  research  to  the  end.  The  action  of  other  hormones  in 
affecting  distant  organs  is  proved,  and  it  is  possible  that  serology'  will  finally  clear 
up  the  mystery.  The  action  of  pituitrin  must  be  borne  in  mind.  Experiments  by 
Sauerbruch  and  von  der  Heide  with  rats  show  that  substances  appear  in  the  blood 
in  the  later  weeks  of  pregnancy  which  cause  disease  in  non-pregnant  animals.  Yon 
der  Heide  injected  fetal  blood-serum  into  pregnant  women  at  term  and  evoked 
labor  pains.  He  explained  the  reaction  as  anaphylactic.  There  also  seems  to  be 
some  serologic  relation  between  the  mammjE  and  the  uterus.     (Healy  and  Kastle.) 


THE  CLINICAL  COURSE  OF  LABOR 

It  will  be  simpler  to  study  the  complicated  problems  of  laljor  if,  first,  we  get  a 
clear  picture  of  its  clinical  course;  that  is,  what  may  be  seen  and  felt  while  attending 
a  woman  in  parturition. 

In  most  primiparjfi  and  many  multiparge  there  is  a  prodromal  stage  of 
labor,  but  in  both  the  symptoms  may  be  so  slight  that  they  may  be  unnoticed, 
and  labor,  therefore,  seems  to  come  suddenly.  The  prodromata  are:  (1)  Light- 
ening, with  its  symptoms,  relief  of  pressure  in  the  upper  belly,  and  increase  of 
pressure  in  the  pelvis,  together  "with  a  mucous  discharge  from  the  vagina.  (2) 
False  pains;  in  the  latter  weeks  of  pregnancy  the  patient  is  often  annoyed  by  con- 
tractions of  the  uterus  which  are  painful.  They  occur  especially  at  night,  subsichng 
toward  morning.  The  uterus  contracts  at  intervals  throughout  pregnane}^,  and 
shows  greater  irritability  near  the  end.  This  sign  is  of  value  in  determining  that 
labor  is  at  hand.  Ordinarily,  the  contractions  are  not  painful  until  actual  labor  sets 
in.  False  pains  may  be  simulated  by  gas  in  the  bowels,  constipation,  and  appendi- 
ceal or  gall-stone  colic.  Many  women  complain  of  drawing  sensations  in  the  pelvis 
similar  to  those  experienced  during  menstruation,  sometimes  amounting  to  pain; 
these  are  called  dolores  prsesagientes,  and  often  accomplish  effacement  and  dilata- 
tion of  the  cervix.  (3)  A))out  twenty-four  or  forty-eight  hours  before  labor  there 
is  a  discharge  of  mucus,  often  mixed  with  blood.  It  is  the  plug  which  formerly 
filled  the  cervix,  closing  off  the  uterine  cavity  from  the  vagina.  The  blood  comes 
from  the  surface  left  bare  by  the  separation  of  the  decidua.  It  is  more  or  less  pro- 
fuse, is  important,  and  is  called  the  "show."  If  the  placenta  is  situated  low  in  the 
uterus,  the  show  is  likely  to  be  quite  bloody.  Occasionally  the  show  does  not 
appear  until  labor  has  been  in  progress  some  time.  (4)  An  examination  in  the  last 
three  weeks  of  pregnancy  shows  the  cervix  soft,  shortened,  perhaps  completely 
effaced — in  primiparse  the  external  os  opened  for  one  or  perhaps  two  fingers.  In 
multiparse  the  cervix  will  admit  two  fingers  to  the  meml)ranes.  Exceptionally,  the 
external  os,  as  well  as  the  internal,  remains  tightly  closed  until  labor  begins,  but

this  is  abnormal,  and  is  usually  due  to  cervical  disease.  Occasionally  the  os  is 
dilated  to  admit  two  or  three  fingers — the  "travail  insensible  "  of  the  French.  How- 
ever, it  is  unsafe  to  predict  with  certainty  the  near  approach  of  labor  from  the  patu- 
lousness  of  the  cervix,  though  it  is  quite  probable.  (5)  The  vulva  is  enlarged,  suc- 
culent, and  patulous,  the  pelvic  floor  projection  very  decided. 

The  transition  into  labor  is  usually  very  gradual,  but  we  say  that  labor  has  be- 
gun when  the  contractions  of  the  uterus  become  sensible  to  the  patient^that  is, 
painful;  when  they  recur  at  regular  intervals,  and  when  they  are  effective  in  dilating 
the  cervix  and  os. 

The  process  of  parturition  naturally  divides  itself  into  three  stages  or  periods: 
The  first  stage  extends  from  the  beginning  of  regular  uterine  contractions  until 
the  os  is  completely  dilated  and  flush  with  the  vagina,  thus  completing  the  continu- 
ous channel  called  the  "parturient  canal."     This  is  the  stage  or  period  of  dilatation. 
The  membranes  usually  rupture  at  the  end  of  this  stage — perhaps  during  it.     The 


Fig.   136. — Composite  Picture  Showing  the  Uterus  before  .\n-d  during  Contr.\ction. 


first  stage  does  not  include  the  rupture  of  the  bag  of  waters,  the  time  of  which  is 
very  variable. 

The  second  stage  extends  from  the  end  of  the  first  stage  until  the  expulsion  of 
the  fetus  is  completed.     It  is  the  stage  of  expulsion. 

The  third  stage  extends  from  the  delivery  of  the  child  until  after  the  expulsion 
of  the  placenta  and  membranes  and  contraction  and  retraction  of  the  uterus  are 
completed.     It  is  the  period  of  the  after-birth,  or  the  placental  stage. 

In  the  first  stage,  recurring  regularly  about  fifteen  minutes  apart,  we  notice  the 
uterine  contractions.  These  are  appreciated  by  the  patient  as  pain,  and  have  been, 
therefore,  designated  by  the  various  races  from  time  immemorial  as  "pains," 
"dolores,"  "douleurs," '"Wehen."  No  normal  labor  is  painless,  though  quite  a 
few  such  have  been  oliserved.  Writers  of  all  ages  have  described  labor  as  painful. 
The  Bible  mentions  it  in  numerous  places.  Accounts  of  uncivilized  race.^  dis]irove 
the  claim  made  bv  some  that  with  them  child-bearing  is  painless.  (See  Ploss, 
"Das  Weib  in  der  Xatur  und  Volkerkunde";  Engelman,  "Labor  Among  Primitive 
Peoples.") 


118 


PHYSIOLOGY    OF   LABOR 


Still,  the  severity  of  the  pain  varies.  Some  races,  especially  the  uncivilized, 
have  generallj^  easy  labors,  whereas  the  highly  cultured  woman  has  hard,  painful 
labors.  This  is  true  to  a  certain  extent,  in  our  civilized  country,  in  the  difference 
between  the  poor  and  the  rich.  The  pain  varies  in  different  women,  and  the  ability 
to  stand  pain  varies  in  women,  as  it  does  in  men. 

As  the  labor  progresses  the  pains  gradually  grow  stronger.  Whereas  at  first 
the  patient  just  bends  over  a  little,  shows  a  change  of  countenance,  after  a  few  hours 
she  may  utter  a  cry.  The  cry  is  simply  one  of  pain,  similar  to  that  of  a  severe  tooth- 
ache or  intestinal  colic.  One  observes  much  individual  difference  in  women  regard- 
ing the  pain  of  labor.     Those  of  quiet,  even  temperament  and  strong  will-power

bear  their  sufferings  bravely  and  aid  the  physician  and  nurse,  while  the  nervous, 
hysteric  parturient  cries  out  even  early  in  the  first  stage,  demanding  an  anesthetic 
or  even  delivery,  and  not  seldom  gives  an  otherwise  normal  labor  a  pathologic  trend. 
The  very  first  pains  are  usually  felt  in  the  small  of  the  back,  but  soon  they  draw 
around  to  the  front  and  are  described  as  grinding,  or  like  a  severe  general  intestinal 
colic.  They  often  seem  to  come  in  pairs — a  mild  one  followed  by  a  severe  one. 
They  last  thirty  to  ninety  seconds  or  longer.  The  character  of  the  pain  varies  in 
different  women,  different  lal)ors,  and  different  times  of  one  labor.  They  may  sub- 
side and  recommence  after  hours  or  days  (rare).  The  patient  is  cheerful  between 
pains  or  may  doze.  As  the  pains  grow  stronger  the  intervals  become  shorter — ten, 
eight,  five,  four  minutes.     During  the  pain  one  observes  the  uterus  contract.     This

begins  before  the  pain  is  felt,  and  ends  after  the  painfulness  is  over  (Fig.  136).  The 
uterus  rises  high  in  the  abdomen,  increases  in  diameter  anteriorly  and  posteriorly, 
and  decreases  laterally,  assuming  a  pear  shape.  At  the  same  time  it  becomes 
tender,  tense,  and  the  ligaments  stand  out  sharpl}'.  There  is  a  stage  of  accrement, 
acme,  and  decrement  in  each  ])ain.

4.  The  membranes  are  bulged  out  through  this.

membranes  being  forced  down  into  the  cervix  like  a  bladder,  cause  a  dilatation  of 
the  cervix  from  above  downward,  and  finally  the  full  opening  of  the  ex-ternal  os.  This 


120  PHYSIOLOGY    OF    LABOR 

dilatation  of  the  cervix  by  the  l^ag  of  waters  is  a  verj'  gentle  and  efficient  one. 
The  whole  force  of  the  uterus  is  not  used,  since  the  head  resting  against  the  lower 
uterine  segment  divides  the  cavity  into  two  parts  (Fig.  137).  The  resistance  at 
A-A  diminishes  the  power  of  C-C,  therefore  the  tension  in  G  is  not  so  great  as  in  B. 
Should  the  body  not  press  fast  to  A-A,  allowing  the  fluid  in  B  to  communicate  with 
the  fluid  in  G,  the  tension  in  G  w^ould  equal  that  of  the  space  of  B.  This  occurs  often 
clinically.  During  a  pain  the  tension  in  B  rises;  therefore  also  of  G,  but  to  a  less 
degree;  when  the  pain  passes  away  the  tension  in  both  subsides.  Thus  it  is  seen 
how  the  head  acts  as  a  ball-valve,  and  becomes,  with  the  membranes,  the  gentlest 
possible  method  to  efface  and  dilate  the  cervix.  Compare  this  to  the  rough  dilata- 
tion which  would  occur  were  there  no  bag  of  waters,  and  if  the  head  were  driven 
through  the  cervix  by  uterine  and  abdominal  forces.  This  happens  when  the  bag 
of  waters  ruptures  before  labor,  especially  in  primiparae.  These  are  called  "dry 
labors,"  and  are  usually  long,  tedious,  and  painful.  Operative  interference  is 
oftener  necessary  in  dry  labors.

Effacement  complete.     Dilatation  just  beginning. 

We  have  used  two  terms  which  need  explanation — efTacement  and  dilatation 
of  the  cervix.     At  the  beginning  of  labor  the  cervix  is  shaped  as  in  Fig.  138. 

By,the  action  of  the  uterus,  which  we  will  later  study  more  minutely,  the  muscle- 
fibers  are  drawn  up  into  the  uterine  body,  the  membranes  are  forced,  pouch  like, 
into  the  cervical  canal,  the  two  processes  resulting  in  a  dilatation  of  the  cervix  from 
above  downward.  The  cervix  is  "taken  up,"  it  is  "obliterated,"  it  is  "shortened," 
it  is  "effaced."  The  latter  term  is  the  one  preferred  by  the  author.  When  the 
cervix  is  so  far  taken  up  that  only  the  external  os  remains,  we  say  that  effacement  is 
complete.  Dilatation  now  begins  (Fig.  143).  When  the  external  os  is  opened  so 
wide  that  it  is  flush,  or  nearly  so,  with  the  vagina,  dilatation  is  complete,  and  the 
child  is  now  able  to  pass  through  it  (Fig.  144).  Coincident  with  the  dilatation  the 
cervix  is  drawn  up  into  the  abdomen,  so  that,  when  the  dilatation  is  complete,  the 
external  os  is  high — almost  out  of  the  reach  of  the  finger.  The  bag  of  waters  usually 
ruptures  at  this  point. 

The  comparison  of  the  parturient  passage  to  the  two  fyjnnels,  one  placed  above 
the  other,  is  quite  apt.  The  child  has  to  pass  first  through  the  upper,  the  cervix, 
and,  second,  through  the  lower,  the  pelvic  floor.  Effacemeiit  of  the  cervix  and  dila- 
tation occasionally  occur  simultaneously,  especially  in  multiparse  (Figs.  141  and  142).

chorion  ruptures,  the  amnion  may  project  through  the  partly  dilated  os  like  a  sac 
(Fig.  148).  If  the  head  fits  closely  onto  the  lower  uterine  segment  and  the  mem- 
branes are  firmly  adherent,  no  bag  of  waters  forms,  and  labor  is  usually  delayed  in 
such  cases  (Fig.  149). 

The  best  time  for  the  membranes  to  rupture  is  when  the  cervix  is  completely 
effaced  and  dilated,  but  they  may  break  at  any  stage,  even  before  the  pains  begin, 
(dry  labor) .  If  the  chorion  ruptures  alone,  the  amnion  may  be  pushed  out,  cover- 
ing the  head  of  the  advancing  child,  and  may  be  delivered  with  the  latter.  The 
child  is  said  to  be  born  with  a  "caul"  and  to  be  lucky.  The  caul  must  be  removed 
as  soon  as  the  head  is  born,  to  allow  the  infant  to  breathe. 

The  rupture  of  the  bag  of  waters  usually  takes  place  at  the  height  of  a  strong 
pain,  and  is  oftenest  central,  the  waters  coming  with  a  gush.  Or  the  rupture  may 
take  place  high  up,  and  the  waters  dribble  away  at  each  pain.     Sometimes  an  ac-

cumulation  of  fluid  between  the  two  membranes  occurs,  and  the  chorion  ruptures 
while  the  amnion  remains  intact.     Thus  we  seem  to  have  two  bags  of  water. 

After  the  rupture  of  the  bag  of  waters  there  is  generally  a  short  pause  in  the 
pains.  The  uterus  needs  time  to  accommodate  itself  to  the  diminished  size  of  its 
cavity  and  for  the  retraction  of  its  muscular  lamellae.  A  few  drops  of  blood  may 
now  appear,  coming  from  decidual  separation. 

Coincidentally  with  these  changes  in  the  cervix  the  fetal  body  has  descended 
lower  into  the  pelvis,  the  bag  of  waters  or  the  head  distends  the  vagina  and  may 
reach  the  pelvic  floor.  It  presses  on  the  nerves  of  the  rectum  and  outlet  of  the  pelvis, 
and  the  parturient  feels  like  bearing  down  as  if  at  stool. 

The  Second  Stage  Has  Begun. — The  pains  grow  stronger,  more  frequent, — 
every  three  or  two  minutes, — and  are  changed  in  character,  being  expulsive.  The 
patient  utters  a  peculiar  cry.  She  feels  there  is  a  body  in  the  pelvis  which  she  must 
force  out;    she  closes  the  glottis,  having  fixed  the  chest  in  inspiration,  braces  the

feet  against  the  bed,  and,  by  a  powerful  action  of  the  abdominal  muscles,  drives  the 
head  downward  against  the  perineum.     During  the  contraction  the  uterus  becomes

board-like  in  hardness.  The  parturient  is  working  hard — indeed,  the  process  is 
righth^  called  labor.  Her  pulse  is  high,  the  veins  of  the  neck  stand  out,  the  thyroid 
is  swollen,  the  face  is  turgid,  the  body  bathed  in  sweat. 


Owing  to  the  pressure  of  the  head  on  the  sacral  and  obturator  nerves  as  they 
go  out  of  the  pelvis,  the  patient  complains  of  pains  radiating  into  the  legs  and  to  the

back.  In  general  the  patient  is  more  hopeful,  since  she  can  help  and  feels  that  there 
is  progress  in  the  labor,  whereas  in  the  first  stage  all  she  had  to  do  was  to  bear  the 
suffering. 

The  perineum  soon  begins  to  flatten  out  and  soften.     The  glands  pour  out  a

sensation  is  due  to  the  head  itself  pressing  on  the  rectum.  After  thirty  to  forty- 
minutes  tlie  anus  begins  to  o}wn,  and,  if  the  woman  lias  hemorrhoids,  these  swell  up 
almost  to  bursting.  Soon  the  labia  part  during  the  height  of  a  pain,  allowing  the 
wrinkled  scalp  to  show.  As  the  pain  subsides  the  clastic  pelvic  floor  forces  the  head 
back.  With  the  next  pain  the  perineum  bulges  more,  the  anus  opens  wider,  so  that 
one  may  see  its  anterior  wall,  the  labia  part  further,  and  a  larger  segment  of  the 
scalp  becomes  visil^le.  As  the  pain  disappears  the  head  recedes.  In  the  interval 
between  pains  the  woman  lies  back  exhausted,  or  may  have  a  few  moments'  re- 
freshing sleep.  When  the  resistance  of  the  pelvic  floor  has  been  thus  gradually 
overcome,  the  head  comes  to  rest  in  the  rima  vulvae,  the  nape  of  the  neck  stemming 
under  the  pubis.  Now,  by  a  crowning  effort,  under  great  nervous  exaltation  and 
powerful  abdominal  action,  the  head  is  forced  out,  the  occiput  coming  from  I)ehind 
the  pubis,  the  forehead,  face,  and  chin  rolling  over  the  perineum.     The  woman  feels

as  if  she  is  being  torn  asunder.  After  this  there  is  a  pause  of  a  few  minutes,  when 
the  pains  are  renewed,  the  shoulders  are  delivered,  and  then  generally  the  trunk, 
in  one  long,  hard,  expulsive  effort.  The  child  gasps,  lying  between  the  thighs  of 
the  mother,  and  soon  cries  vigorously.  A  little  blood  and  the  rest  of  the  licjuor  aninii 
and  the  ends  of  the  membrane  are  now  discharged.  The  uterus  contracts  down  into 
a  ball.  The  patient  feels  much  relieved.  She  may  have  a  chill  now,  but  this  is 
considered  physiologic.  It  may  occur  after  the  placenta  is  expelled  and  is  not  con- 
stant. The  cause  of  this  chill  has  been  much  discussed.  The  author  has  seen  fewer 
and  fewer  chills  with  the  perfection  of  the  aseptic  technic  of  labor,  and  is  inclined  to 
believe  they  are  due  to  absorption  of  toxins  from  the  parturient  canal.  Abdominally, 
one  finds  the  uterus  contracted  to  a  ball  the  size  of  a  cocoanut.  It  still  has  the  work 
of  delivering  the  placenta.  The  second  stage  is  ended.  The  physician  severs  the 
cord,  separating  the  child  from  the  placenta,  and  this  act  establishes  the  legal  status 
of  the  child  as  an  individual.

PHYSIOLOGY   OF   LABOR 


The  Third  or  Placental  Stage.— After  from  five  to  twenty  minutes,  devoted  to 
rearrangement  of  its  muscular  lamellse,  the  uterus  begins  to  contract  again.  Some 
blood  usually  appears  externally  with  the  first  pain.  The  uterus  at  first  is  somewhat 
relaxed,  slightly  flattened,  but  during  a  pain  it  becomes  smaller,  harder,  and  glob- 
ular. The  after-pains  are  usually  not  very  painful;  often  the  patient  perceives  only 
a  slight  drawing  sensation,  but  the  accoucheur  can  feel  the  regular  (four  to  five 
minutes)  contractions.  After  a  period  varying  from  a  few  minutes  to  an  hour  or 
more  the  fundus  uteri  rises  high  in  the  abdomen,  generally  under  the  liver,  while

below,  over  the  pubis,  the  abdomen  feels  soft  and  boggy  (Fig.  153).  At  the  same 
time  the  cord  advances  a  few  inches  from  the  vulva.  These  signs  indicate  that  the 
placenta  has  loosened  from  the  uterine  wall  and  has  descended  into  the  lower  uterine 
segment  and  upper  part  of  the  vagina.  When  the  placenta  is  in  the  uterus,  the 
organ  is  large  and  globular.  When  the  placenta  has  been  forced  from  its  bed  into 
the  lower  uterine  segment  and  upper  vagina,  the  uterus  assumes  a  flattened  pear 
shape.  The  flattening  is  from  before  backward  and  the  fundus  is  sharp.  On  the 
anterior  or  posterior  surface  often  a  broad,  shallow  dimple  is  to  be  felt — the  site  of 
the  placenta.     After  a  few  contractions  or,  if  blood  accumulates  in  the  uterus,  its 


DEP^INITION — CAUSES — CLINICAL    COURSE 


129 


shape  again  becomes  more  globular.     The  sharp  fundus  and  the  flat  dimple  are 
other  evidences  that  the  placenta  has  left  the  uterine  cavit}'. 

After  a  period,  if  the  patient  is  let  alone,  varying  from  fifteen  minutes  to  three 
liours  or  longer,  the  placenta  is  spontaneously  expelled  ])y  the  combined  efforts  of 
the  abdominal  muscles  and  the  uterus.  Generally,  the  attendant  does  not  wait  for 
this  termination,  but  completes  the  process  himself.  The  placenta  is  usually  in- 
verted like  an  umbrella,  and  draws  the  membranes  after  it,  peeling  them  off  the 
uterine  wall  (Schultze's  method).  Sometimes  the  placenta  slides  out  without  doub- 
ling up,  the  lower  portion  appearing  first  (Duncan's  method).     With  tlu"  after-

V)irth  a  less  or  greater  quantity  of  blood  is  discharged.  Now  the  uterus  contracts 
down  into  a  hard  lump  in  the  inlet  of  the  pelvis,  extending  to  the  navel.  It  is  of  the 
size  of  a  fetal  head. 

The  third  stage  is  ended.     The  puerperium  has  begun.     The  parturient  has 

become  a  puerpera. 

THE  PAINS 
The  uterine  contractions,  the  most  prominent  symptom  of  labor,  deserve  more 
consideration. 

1.  They  are  involuntary.     The  woman  has  no  control  over  them,  but  they  are 
under  the  domain  of  the  cerebrospinal  system.     A  mental  shock  may  augment  or

PHYSIOLOGY    OF    LABOR 


paralyze  the  uterine  action.  For  instance,  the  aljrupt  entrance  of  a  stranger  may 
"drive  the  pains  away."  In  one  case  of  exceedingly  slow  labor  the  author  expressed 
his  intention  to  insert  a  colpeurynter.  Strong  pains  came  on  at  once  and  delivery 
was  effected  within  an  hour. 

2.  The  action  of  the  uterus  is  not  peristaltic  to  the  degree  that  exists  in  animals. 
The  uterus  may  contract  in  one  portion,  the  hardening  extending  quickly  all  over. 
This  the  author  has  repeatedly  observed  after  delivery  of  the  child  in  cesarean  sec- 
tions. Portions  of  the  uterus  may  contract  while  the  rest  remains  in  a  state  of  re- 
traction— for  instance,  "hour-glass"  contraction;    cornual  contraction.

3.  The  action  of  the  uterus  is  intermittent — that  is,  the  pains  recur  at  intervals. 
This  intermittence  aids  the  circulation  in  the  parts.  During  uterine  systole  the 
blood  in  the  veins  is  forced  toward  the  broad  ligaments;  during  diastole  the  uterus 
becomes  turgid — ^to  be  observed  at  cesarean  sections.  Pelvic  congestion  is  thus 
produced,  and  the  resulting  succulence  of  the  cervix  and  vagina  is  a  strong  factor  in 
their  dilatation.  By  coordinated  action  the  arteries  dilate  and  more  blood  is  brought 
to  the  uterus  (Werth).  The  blood  in  the  uterine  sinuses  would  be  stagnant  were 
it  not  for  these  intermittent  uterine  contractions,  which  much  resemble  the  action 
of  a  local  heart.     The  fetus  is  thus  provided  with  sufficient  oxygen.     In  cases  of

tetanus  uteri  the  child  may  die  of  asphyxia  l^ecause  the  hard,  contracted  uterus  will 
not  allow  enough  blood  to  flow  through  it. 

The  intermittence  provides  for  the  necessary  rest  of  the  muscle,  the  removal  of 
waste,  and  the  proper  application  of  uterine  force  to  the  mechanical  object  of  labor. 
The  uterine  action  is  a  beautiful  example  of  applied  power. 

4.  The  contractions  are  rhythmic,  having  three  phases — increment,  acme,  and 
decrement.  The  increment  is  longer  than  the  acme  and  decrement  (Figs.  155  and 
156).  Schatz  placed  rubV)er  bags  in  the  functionating  uterus  and  registered  the 
pressure  variations  with  a  manometer,  calling  the  apparatus  a  "tokodynamometer." 
His  work  is  classic.    The  pain  lasts  from  sixty  to  ninety  seconds,  the  intervals  from  a 


DEFINITION — CAUSES — CLINICAL    COURSE  131 

few  seconds  to  an  hour,  depending  on  tlie  stage  of  labor  and  individual  characteris- 
tics. Some  pains  are  double.  Sometimes  a  weak  pain  precedes  a  strong  one.  The 
first-stage  pain  differs  from  that  of  the  second  stage.  The  addition  of  the  abdomi- 
nal pressure  alters  the  character  of  the  curve.     (Compare  Figs.  155  and  156.) 

The  contraction  is  well  under  way  before  the  patient  feels  the  pain,  and  con- 
tinues a  short  time  after  the  pain  is  gone.  The  pains  grow  stronger  with  the  in- 
creased frecjuency.  The  educated  hand  laid  on  the  abdomen  can  discovernearly 
all  these  points. 

5.  The  uterine  contractions  are  painful.  No  other  bodily  function  involving 
contraction  of  unstriped  muscle  is  painful,  and  why  these  should  be  is  incompre- 
hensible if  labor  is  to  be  considered  a  normal  function. 

Before  labor  has  actively  begun  the  pains  are  called  dolores  pra?sagientes. 
When  the  os  is  beginning  to  dilate,  they  become  quite  painful,  and  are  called  dolores 
prseparantes.  They  seem  to  have  their  seat  in  different  places — sometimes  in  the 
back,  in  the  pelvis,  again  in  the  abdomen. 

The  first  pains  of  labor  are  felt  in  the  back,  near  the  kichieys,  and  are  called  by 
the  French  women  "pains  of  the  kidneys."  They  may  be  felt  only  as  a  sensation  of 
weakness,  and  the  patient  supports  her  back.  Later  the  pains  are  felt  more  in  the 
pelvis.  In  the  first  stage  the  pain  is  due  to  the  pressure  of  the  presenting  part  on 
the  nerves  of  the  cervix,  to  the  stretching  of  the  same  during  the  dilatation  of  the  os 
by  the  presenting  part  (]\Iadame  Boivin,  who  had  personal  experience),  or  to'  the 
compression  of  the  nerves  in  the  wall  of  the  uterus.  Perhaps  all  three  causes  are 
combined.  The  pains  are  described  by  the  women  as  grinding,  twisting,  or  re- 
sembling severe  abdominal  colic. 

The  pain  in  the  §mall  of  the  back  is  due  to  radiation,  such  as  is  common  in 
pelvic  neuralgias.  The  nerves  involved  are  the  sacral  and  lumbar  plexuses.  The 
pain  caused  by  the  dilatation  of  the  last  fibers  of  the  cervix  is  particularly  acute, 
and  sometimes  a  slight  amount  of  blood  may  show  itself,  indicating  a  tear  in  the 
external  os. 

When  the  head  passes  down  into  the  vagina  and  begins  to  press  on  the  perineum, 
the  pains  are  due  to  the  stretching  of  these  parts  and  are  spoken  of  as  tearing. 

The  patient  now"  bears  down  and  the  pain  cry  is  altered.  She  does  not  com- 
plain so  much,  but  helps  the  labor  along  l^y  pressing  down  with  the  abdominal 
muscles.  When  the  head  goes  through  the  vulva,  the  greatest  anguish  is  felt,  the 
patient  feeling  as  if  she  were  torn  open  (dolores  conquassantes).  The  pain  may  be 
so  great  that  the  patient  faints  or  is  temporarily  insane,  but  both  are  rare. 

These  pains  are  called  dolores  ad  partum.  After  the  birth  of  the  child  the 
uterine  contractions  are  called  after-pains,  or'dolores  ad  secundum  partum.  They 
usually  are  not  so  severe  as  the  others,  but  in  some  patients  they  are  very  painful. 

After  delivery  the  pains  are  called  dolores  post  partum,  or  "after-pains,"  and, 
especially  in  multiparae,  chsturb  the  first  days  of  the  puerperium,  often  requiring 
treatment. 

Painless  labors  do  occur,  but  are  very  rare.  If  not  due  to  disease  of  the  spinal 
cord,  it  is  hard  to  explain  them.  The  women  feel  simply  the  desire  to  strain,  as  at 
stool,  and  delivery  is  usually  quick.  "Christian  Scientists"  claim  to  have  no  pain, 
but  I  have  often  observed  they  present  positive  evidences  of  suffering,  reminding 
one  of  the  stoical  martyrs  in  Rome. 


CHAPTER  VII 
THE  EFFECTS  OF  LABOR  ON  THE  MATERNAL  ORGANISM 

It  is  not  to  be  expected  that  a  process  requiring  so  much  muscular  exercise, 
such  anxiety,  and  accompanied  by  such  pain,  can  be  without  a  strong  influence  on 
the  maternal  organism.  The  patient  eats  little,  sometimes  vomits,  is  usually  rest- 
less, and  does  not  sleep  much  during  labor.  She  may  even  have  had  pain  at  nights 
and  very  little  sleep  for  a  week,  both  of  which  exhaust  her.  A  labor  lasting  a  few 
days  leaves  the  patient  weak  and  completely  tired  out,  but  this  depends  on  the 
length  of  the  labor  and  the  strength  of  the  woman  in  the  first  place. 

The  Duration  of  Labor. — The  length  of  parturition  is  variable,  which  is  true 
also  of  the  same  woman  in  different  labors.  In  the  uncivilized  races  labor  is  some- 
what shorter.  It  is  said  that  some  Indian  women,  while  the  tribe  is  on  the  march, 
feeling  the  pains  of  labor  coming  on,  go  off  to  the  side  in  the  underbrush,  bear  the 
child,  and,  after  expressing  the  after-ljirth,  hurry  to  catch  up  with  the  rest  of  the 
train,  but  this  is  exceptional,  and  later  writers  tell  us  that  obstetric  disease  and 
mortality  are  large  among  the  uncivilized  races. 

In  primiparse  labors  are  longer  than  in  multiparse;  labor  is  shorter  in  warm 
climates,  also  during  summer;  in  poor,  hard-working  women  than  in  the  rich  and 
pampesred;  therefore  shorter  in  the  country  than  in  the  city. 

The  size  of  the  fetus  has  a  great  deal  to  do  with  it^a  large  fetus,  long  labor. 
The  same  holds  true  if  the  fetal  head  is  large  and  hard.  In  young,  strong  primiparse 
labor  is  easier  than  in  old  primiparse,  the  average  in  the  latter  being  twenty-seven 
hours,  but  one  is  often  surprised  to  see  an  easy  labor  in  a  primiparous  patient  over 
forty  years  old.  Labor  is  longer  in  fat  women,  longer  -svdth  boys  than  with  girls, 
because  they  are  larger.  The  lengths  of  the  various  stages  of  labor  are  about  as 
follows:  Primiparse,  first  stage,  sixteen  hours;  second  stage,  one  and  three-quarter 
to  three  hours;  third  stage,  from  a  few  minutes  to  several  hours.  ]Multiparse,  first 
stage,  twelve  hours;  second  stage,  one-quarter  to  one-half  hour;  third  stage,  from 
a  few  minutes  to  several  hours. 

Extremes  are  not  rare.  We  have  had  cases  where  labor  was  completed  in  even 
less  than  one  hour.  Again,  there  are  labors  which  are  slow  from  the  start,  requiring 
days  for  completion.  Labor  may  intermit,  an  interval  of  hours  or  days  occurring 
after  the  pains  have  begun  and  dilatation  of  the  os  has  been  effected.  The  differ- 
ence in  the  lenglh  of  lal)or  in  primiparse  and  multiparse  is  due  to  the  slowness  of 
dilatation  of  the  cervix,  perineum,  and  vulvar  orifice  in  the  former.  In  multiparse, 
o\\ang  to  stretching  by  previous  deliveries,  the  resistances  offered  by  the  soft  parts 
are  less  and  much  more  readily  overcome.  If  many  years  elapse  between  deliveries, 
some  of  the  original  resistance  may  have  been  regained. 

In  1000  labors  at  the  Chicago  Lying-in  Hospital  the  pains  began  as  follows:

The  Temperature. — The  muscular  exertion  during  labor  wotild  raise  the  tem- 
perature if  tlic  loss  of  heat  were  not  so  great.  Perspiration  is  increased,  exposure  of 
the  body  greater,  resi^iration  faster- — all  tend  to  keep  the  woman's  temperature  near 
normal.  Accurate  taking.s  have  shown,  however,  that  there  is  a  slight  rise  during 
labor,  which  is  greatest  right  after  delivery  of  the  child,  and  varies  with  the  usual 
daily  variations,  but  does  not  normally  exceed  1°F.  During  the  pain  the  tempera- 
ture rises  a  little.  The  temperature  is  likely  to  rise  during  a  prolonged  second  stage. 
Overstrain  and  sleeplessness  conduce  to  it  (Adami).  The  author  is  convinced  that 
fever  of  more  than  one  degree  during  labor  is  toxinemic  or  septic  in  origin,  and  comes 
from  the  absorption  of  toxins  or  bacteria  from  the  puerperal  wounds.  H.  ]\Iuller 
came  to  the  same  conclusion.  With  the  perfection  of  an  aseptic  technic  slight  fevers 
in  labor  are  very  rare,  and  the  postpartum,  so-called  "physiologic,"  chill  has  become 
almost  unknown.  The  chill  formerly  was  ascribed  to  exhaustion  of  the  mother,  pro- 
longed exposure  of  her  person,  loss  of  a  source  of  heat,  the  child,  readjustment  of 
the  abdominal  circulatory  conditions,  nervousness,  etc.,  but  the  author  believes 
that  the  chill,  too,  is  due  to  infection  during  labor.  Proof  of  this  is  hard  to  bring, 
but  if  the  other  causes  mentioned  were  real,  the  chill  ought  to  follow  nearly  everj' 
labor,  whereas  statistics  show  that  it  occurs  in  only  20  to  30  per  cent.  In  the 
author's  practice  it  has  almost  disappeared  \\-ith  the  perfection  of  asepsis,  the  use 
of  rubber  gloves,  and  the  restriction  of  the  internal  examinations.  If  not  due  to 
infection,  the  possibilit}'  that  it  might  be  of  an  anaphylactic  nature  is  to  be 
considered. 

The  Circulation. — The  rate  of  the  heart-beat  increases  somewhat  during  labor, 
reaching  100  or  110,  but  between  the  pains  may  be  normal.  The  advent  of  a  pain 
is  heralded  by  a  faster  heart-beat.  In  the  second  stage,  during  the  severe  muscular 
exertion,  the  pulse-rate  increases  a  good  deal,  but  in  the  third  stage,  if  no  hemor- 
rhage be  present,  it  is  usually'  normal.  Any  marked  rapidity  must  put  you  on  your 
guard  against  hemorrhage,  external  or  internal.  Arterial  tension  is  increased  until 
after  the  third  stage  unless  there  is  hemorrhage  or  chloroform  narcosis.  During 
the  pain  the  arterial  tension  is  greater  than  in  the  intervals,  and  a  moderately 
heightened  blood-pressure  continues  a  few  days  into  the  puerperium.  The  edu- 
cated finger  can  determine  these  points,  but  the  newer  instrument,  the  sphygmo- 
manometer, proves  them  scientifically  (Slemons).  In  order  to  make  a  firm  support 
for  the  action  of  the  abdominal  muscles  in  the  second  stage,  the  parturient  fLxes  the 
chest  in  inspiration  and  holds  her  breath.  If  the  bearing-down  efforts  are  very 
hard  and  prolonged,  the  pulmonary  circulation  is  interfered  with,  the  right  heart  is 
congested,  the  blood  cannot  get  into  the  chest,  there  is  marked  turgidity  of  the  veins 
of  the  neck  and  head,  and  from  this  there  sometimes  result  enlargement  of  the  thy- 
roid, which  disappears  postpartum,  edema  of  the  face,  even  tiny  hemorrhages  in 
the  conjunctivae.  These  evidences  of  venous  congestion  are,  in  bad  cases,  found 
also  in  the  brain  (Hodge). 

The  respirations  are  increased  during  the  pains,  but  between  pains  are  nonual. 
Some  nervous  women  hold  the  breath  during  the  pains,  even  in  the  first  stage.  In 
the  second  stage  breathing  is  more  rapid,  irregular,  and  altered  by  the  l)earing-down 
efforts  and  cries  of  pain.  In  the  third  stage  they  are  again  normal,  unless  there  be 
hemorrhage,  when  an  increase  in  number,  or  gasping,  shortness  of  breath,  persistent 
yawning,  shows  that  there  is  something  MTong.

the  temperature.  Too  rapid  breathing  may  produce  acapnia,  a  condition  which 
bears  some  relation  to  shock.  Emphysema  of  the  chest  and  head  may  result  from 
too  powerful  bearing-down  efforts. 

Turgidity  and  swelling  of  the  turbinate  bones  are  usually  observed  during 
labor.  If  the  patient  has  a  nasal  catarrh,  obstruction  of  the  nares  may  result. 
Fliess  associates  this  condition  with  the  uterine  action,  and  claims  that  the  latter 
may  be  influenced  by  treatment  directed  to  the  nose. 

The  Intestinal  Tract. — Anorexia  is  the  rule.  Thirst  is  common.  IMany  women 
vomit  during  labor.  The  old  midwives  say  that  sick  labors  are  easy,  but  the  author 
cannot  confirm  this.  It  was  once  the  custom  to  give  emetics  on  this  theory  to 
relax  the  cervix,  but  the  practice  is  bad.  When  the  head  is  passing  through  the  os, 
the  great  distention  may  cause  reflex  vomiting,  and  some  women  vomit  frequently 
during  the  second  stage.  Persistent  vomiting  at  any  stage  of  labor  should  always 
be  suspected,  and  its  cause  sought  for  carefully.  It  may  indicate  threatened  or 
actual  rupture  of  the  uterus,  eclampsia,  uremia,  internal  hemorrhage,  peritonitis. 
In  the  third  stage  vomiting  almost  never  occurs  normally.  Anesthesia,  especially 
after  operations,  may  cause  it,  but  even  then  it  is  rarely  so  severe  as  in  surgical  cases. 
Persistent  nausea  and  vomiting  after  a  delivery  are  a  significant  symptom,  and  their 
cause  must  be  discovered. 

The  bowels  are  often  loose  at  the  very  beginning  of  labor,  and  borborygmus  is 
often  heard  during  its  progress,  but  the  head  in  the  pelvis  prevents  defecation.  In 
the  second  stage  the  advancing  head  forces  feces  from  the  rectum,  an  occurrence 
annoying  to  the  mother,  and  dangerous,  too,  because,  in  the  manipulations  the 
doctor  makes  he  may  carry  infectious  matter  into  the  parturient  tract.  A  cathartic 
given  in  labor  may  stimulate  the  pains — an  old  remedy  for  inertia  uteri. 

The  mental  condition  of  the  patient  during  the  first  stage  of  labor  usually  does 
not  differ  from  that  of  a  woman  suffering  pain.  In  predisposed  women  it  may  be 
marked  by  hysteric  manifestations.  In  the  second  stage,  especially  at  the  end,  the 
parturient  may  become  delirious  or  even  maniacal  from  the  suffering,  but  this  is 
rare.  Real  fainting  is  also  rare  in  normal  labors.  Whenever  I  have  seen  it,  the 
cause  has  been  hemorrhage  or  shock.  That  a  woman  may  give  birth  during  a  faint 
is  theoretically  certain  and  medicolegally  proved.  This  is  important  from  a  legal 
standpoint,  as  in  cases  of  infanticide.  (For  full  consideration  of  this  subject  see 
Moritz  Freyer.) 

The  woman's  demeanor  is  usually  cheerful,  but  may  be  the  opposite,  she  as- 
serting her  inability  to  bear  the  pain  or  that  she  will  surely  die.  In  the  second 
stage,  when  the  parturient  feels  the  progress  of  the  head,  she  complains  less.  Be- 
tween pains  the  woman  ma}"  doze  or  sleep  soundly. 

When  the  head  enters  the  lower  pelvis,  it  may  compress  the  obturator  or  sacral 
nerves.  Cramps  in  the  leg  are  thus  produced — in  the  anterior  upper  thigh  in  the 
former,  on  the  posterior  surface  of  the  leg  in  the  latter,  instance. 

After  the  child  is  delivered  the  parturient  may  fall  asleep,  which  is  especially 
common  at  the  end  of  prolonged,  exhausting  labors. 

The  Urinary  System. — The  disposition  of  the  bladder  during  labor  varies  in 
different  women.  Usually  the  lower  uterine  segment  in  its  development  pulls 
away  from  the  viscus,  leaving  it  behind  the  pubis,  but  in  some  cases,  where  the  two 
organs  are  more  intimately  adherent,  the  bladder  rises  into  the  abdomen  with  the 
lower  portion  of  the  uterus.  In  either  case  the  full  bladder  distends  the  lower  hypo- 
gastrium,  but  there  is  a  difference  in  the  depth  of  the  anterior  culdesac. 

The  ureters  are  also  drawn  upward  with  the  receding  uterus.  Early  in  labor 
they  may  be  felt  coursing  around  the  cervix  toward  the  brim  of  the  pelvis.  Later 
one  cannot  feel  them.  Frozen  sections  (Tandler)  show  that  they  cross  the  brim 
higher  and  more  anteriorly  than  in  the  non-pregnant  state.  The  urethra  is  length- 
ened, compressed  by  the  head,  and  much  bruised  during  labor.     If  the  head  is  too

135 


long  impacted  in  the  pelvis  the  urethra  and  part  of  the  bladder  may  slough  out, 
leaving  urinary  fistulas. 

In  general  the  kidneys  are  more  active  during  lal)or.  The  polyuria  is  due  to 
the  heightened  arterial  tension  and  stimulation  of  the  kidneys  through  the  sympa- 
thetic from  the  uterus.  In  nervous  or  hysteric  women  the  general  nervous  system 
plays  a  part.  Polyuria  is  usual,  but  not  constant,  some  women  having  less  than 
normal.  The  full  bladder  disturl)s  the  course  of  lal^or,  may  prevent  the  engage- 
ment of  the  head,  and  in  the  third  stage  may  delay  the  exit  of  the  placenta  and 
cause  postpartum  hemorrhage. 

The  specific  gravity  of  the  urine  is  reduced,  urea,  phosphate,  and  sulphate

content  also,  while  the  sodium  chlorid  is  increased  (v.  Winckel).  Albumin  is  found 
in  one-fifth  of  the  cases,  being  three  times  commoner  in  primiparse,  more  freciuent 
in  very  young  and  very  old  parturients,  in  hard  and  prolonged  labors,  after  the 
administration  of  anesthetics,  with  fever  in  labor,  and  in  women  who  have  had  al- 
buminuria tluring  pregnancy.  The  amount  in  normal  cases  does  not  exceed  1/1000 
Esbach.  Larger  quantities  indicate  pathogenic  conditions.  The  cause  of  the 
albuminuria  may  be  sought  in  the  increased  muscular  exertion  of  labor,  the  high 
blood-pressure,  and  perhaps  in  the  deportation  of  placental  villi  (Veit)  under  the 
force  of  the  uterine  contractions.     (See  Eclampsia.) 

Formed  elements,  especially  hyaline  casts,  are  often  found,  even  white  and  red 
blood-corpuscles,  all  three  in  proportion  to  the  albuminuria.     In  general,  it  may  be

said  that  the  urinary  findings  during  labor  bear  only  slightly  less  significance  than 
at  any  other  time  during  pregnancy. 

General  Metabolism.— The  mother  loses  about  one-tenth  of  her  body  weight 
(Baumm  and  Gas.sner).  This  is  made  up  of  the  child,  the  placenta  and  membranes, 
the  liquor  amnii,  blood,  excretions  from  the  skin,  lungs,  kidneys,  etc.     The  average

loss  is  6564  gm.,  of  which  5000  fall  to  the  ovum,  1000  to  the  liquor  amnii,  and  there 
is  a  loss  of  about  400  gm.  of  blood. 

A  marked  leukocytosis  is  found  during  labor,  which,  according  to  Hofl)auer,  is 
due  to  muscular  work,  but  is  more  probably  an  antitoxic  reaction.  The  whites 
vary  from  9  to  34,000.  The  polynuclear  neutrophils  are  increased,  the  eosinophiles 
much  decreased  (Cova). 

Parturition  is  the  only  function  normally  attended  liy  hemorrhage.  Bloodless 
labors  are  rare,  and  are  so  usually  because  the  fetus  has  been  dead  some  weeks. 


THE    EFFECTS    OF   LABOR   ON    THE    MATERNAL    ORGANLSM  137 

The  amount  of  ])loo(l  lost  varies  in  wide  limits  from  a  few  ounces  to  several  quarts. 
Where  the  normal  limit  lies  depends  on  the  individual  patient.  Authorities  differ  as 
to  what  should  be  considered  normal.  Ahlfeld  says  even  1000  gm.  may  be  a 
normal  loss,  but  that  the  average  is  400  gm.  The  amount  of  blood  lost  is  influenced 
by  the  size  of  the  child,  the  area  of  the  placenta,  its  location  in  the  uterus,  the  rajiid- 
ity  of  the  separation  of  the  placenta,  the  strength  of  the  uterine  contraction  and  re- 
traction, the  age  of  the  parturient,  and  the  number  of  children  she  has  borne,  being 
greater  in  multiparse.  The  method  of  conduct  of  the  labor  by  the  medical  attendant 
also  influences  the  blood  loss  and  pathologic  conditions  to  l)e  later  considered.  Xo 
exact  figure  may  be  given  as  to  what  is  a  normal  loss  of  blocxl  in  labor.  The  author 
believes  that  500  gm.  should  be  the  limit  in  ordinary  cases,  and  that  in  small,  anemic, 
or  otherwise  debilitated  women  the  loss  should  not  exceed  150  gm.  Nearly  all  the 
blood  comes  during  and  after  the  third  stage,  either  free  or  contained  in  the  folded 
placenta  as  the  retroplacental  hematoma.  A  little  blood  appears  in  the  "show" 
at  the  beginning  of  the  first  stage;  a  little  more  comes  w4ien  the  last  fibers  of  the 
cervix  are  giving  way;  more  may  appear  when  the  head  bursts  through  the  vulva, 
from  tears  of  the  clitoris  and  outlet.  The  bleeding  now  comes  from  the  placental 
site  and  cervical  and  perineal  lacerations,  and  when  the  placenta  comes,  the  greatest 
discharge  occurs.  The  oozing  after  the  delivery  of  the  placenta  comes  from  the 
placental  site  and  the  puerperal  wounds,  and  in  the  first  two  hours  should  not  exceed 
two  ounces.

CHAPTER  VIII 
THE  EFFECT  OF  LABOR  ON  THE  CHILD'S  ORGANISM 

During  the  last  weeks  of  pregnancy  the  child  is  quieter,  due  to  the  restriction 
of  its  movements  from  lack  of  room.  The  question,  Does  the  child  suffer  pain 
during  delivery?  has  been  answered  both  ways.  It  probably  does.  The  author 
has  felt  the  infant  withdraw  its  hand  after  being  pinched,  and  the  infant,  a  few 
seconds  after  birth,  cries  lustily  when  spanked. 

A  not  small  percentage  of  children  die,  even  in  so-called  normal  labor — esti- 
mated by  various  authors  from  3  to  5  per  cent.  In  Paris  it  is  9  per  cent.  (Cham- 
brelent).     The  shock  of  labor  to  the  infant  must  be  reckoned  with. 

Careful  examination  of  the  fetal  heart  during  labor  shows  that  its  rapidity  is 
much  affected  by  the  pains.  When  the  uterus  begins  to  contract,  the  fetal  pulse 
beats  faster;  during  the  height  of  the  pain  it  is  slow;  as  the  pain  wanes  it  beats  fast 
again,  gradually  slowing  down  to  normal.  These  findings  are  more  pronounced 
after  the  membranes  are  ruptured  and  with  strong  pains.  Sometimes  the  heart  is 
accelerated  by  the  pains.     As  labor  progresses  the  fetal  heart  usually  becomes

slower,  and  as  the  head  passes  through  the  pelvic  floor,  the  slowing  may  be  so  marked 
that  the  attendant  becomes  alarmed.  The  author  has  counted,  during  the  pains, 
a  beat  as  low  as  60  while  the  head  was  being  delivered.  A  consideration  of  the  fetal 
heart-beat  as  an  indication  of  danger  to  the  child  will  be  reserved  for  the  chapter  on 
Asphyxia  Neonatorum.  The  cause  of  these  variations  is  unknown.  Schultze 
ascribes  them  to  stimulation  of  the  vagus  by  the  insufficiently  oxidized  fetal  blood, 
the  uterine  contraction  forcing  the  maternal  blood  out  of  the  placenta.  Kehrer 
believed  that  the  compression  of  the  skull  slowed  the  heart  by  direct  vagus  irritation. 
Probably  both  explanations  apply.  The  slowing  of  the  heart  is  not  constant;  the 
author  has  noticed  that  the  pulse  does  not  vary  much,  in  some  few  labors,  from  the 
beginning  to  the  end.  When  the  child  is  in  danger,  its  heart  beats  verj^  fast,  very 
slowly,  or  irregularly,  yet  occasionally  we  note  these  signs  and  the  child  does 
not  suffer.  The  child  may,  in  pathologic  cases,  make  respiratory  movements 
before  its  delivery.  Even  in  normal  deliveries  close  observation  of  the  head  as  it 
lies  in  the  vulva  will  discover  little  twitchings  that  indicate  attempts  to  inspire,  and 
the  accoucheur  will  find  that  the  infant  has  filled  its  mouth  with  blood  or  mucus 
from  the  vagina.     Von  Winckel  discovered  these  movements  by  examinations  by

the  rectum.  It  is  wise  to  hasten  the  delivery  when  such  action  is  (Hscovered,  be- 
cause the  infant  may  get  foreign  matter  into  the  lungs  or  stomach  and  later  develop 
pulmonary  atelectasis  or  intestinal  infection.  Occasionally  the  infant  will  gasp  and 
cry  as  soon  as  the  head  is  out,  but  usually  the  first  cry  escapes  after  the  body  is  de- 
livered. At  first  the  chest  moves  with  tiny  excursions;  in  a  few  moments  a  deep 
gasp  fills  the  lungs,  then  comes  a  sneeze  or  a  cough,  which  expels  the  mucus  from  the 
throat,  following  which  is  the  lusty  cry  of  the  new-born. 

The  Cause  of  the  First  Respiration. — The  theory  of  Preyer,  that  the  irritation 
of  the  skin  from  the  trauma  of  labor  causes  the  respiration  by  stinuilating  the  respira-

tory  center  reflexly,  is  not  probable.  The  child  in  utero  exists  in  a  state  of  apnea. 
Stimuli  applied  in  this  condition  have  no  effect  on  the  center,  as  is  shown  by  clinical 
experience.  Rough  palpation,  attempts  at  version,  forceps,  do  not  affect  the  child 
in  utero.  Should  the  child,  however,  be  partly  asphyxiated,  the  respiratory  center 
will  react  to  these  stimuli.  The  theory  that  the  exposure  to  cold  when  the  child 
is  born  causes  the  respiration  has  ])een  refuted.  Ahlfeld  delivered  several  children 
into  warm  saline  solution  and  the  respiration  began  as  usual.  Again,  sometimes  a 
half-minute  will  elapse  before  the  first  gasp  occurs,  and  a  reflex  shoukl  l)e  quicker 
than  this.  The  most  accepted  theory  is  that  the  gradual  deoxidation  and  hyper- 
carbonization  of  the  blood  make  the  respiratory  center  more  irritable  (Schwartz). 


140 


PHYSIOLOGY    OF   LABOR 


This  condition  occurs  in  the  latter  months  of  pregnancy,  due  to  the  gradual  narrow- 
ing of  the  ducti  arteriosus  and  venosus.  During  labor  this  partial  asphj'xia  is  in- 
creased. When  the  child's  head  is  born,  the  placenta  is  beginning  to  separate,  and 
when  the  baby  is  delivered,  the  placenta  is  almost  completely  detached.  As  a 
result,  the  fetus  passes  from  a  condition  of  apnea  to  one  of  dyspnea,  the  respiratory 
center  is  irritated,  and  respiration  begins.  The  same  condition  occurs  in  atero 
when  the  placental  circulation  is  cut  off.     A  slightly  asphyxiated  child  responds

promptly  to  external  stimuli,  such  as  cold,  slapping,  friction.  If  the  child  is  rapidly 
delivered,  as  in  cesarean  section,  or  in  nmltipar®  with  a  short  second  stage,  it  may 
come  into  the  world  with  sufficient  oxygen  for  a  short  time;  it  is  in  its  intra-uterine 
condition  of  apnea,  and  a  few  minutes  may  elapse  before  the  respiratory  center  be- 
comes sufficiently  irritated  by  the  increasingly  venous  blood  to  evoke  respiratory 
action. 

The  Changes  in  the  Fetal  Circulation.— ^^lth  the  first  inspiration  the  lungs  ex-

right  ventricle.  There  is  no  blood  to  pass  throuf^h  the  ductus  Botalli.  It,  therefore, 
collapses.  This  may  be  due  to  a  valve-like  formation  at  its  junction  with  the  aorta 
(Strassman)  or  to  a  twisting  of  the  duct,  due  to  the  change  of  position  of  the  heart, 
caused  by  the  filling  of  the  auricles  and  distention  of  the  lungs.  There  is  less  blood 
coming  from  the  ascending  vena  cava,  the  umliilical  vein  contracting;  the  pressure 
in  the  right  auricle  sinks.  The  result  is  an  asj^iration  toward  the  heart  of  the  blood 
in  the  vena  cava  and  umbilical  vein. 

The  distal  ends  of  the  hypogastric  arteries  contract  and  thrombose.     This  is 
due  to  the  fact  that  the  left  ventricle  cannot  send  the  blood  the  long  distance  through

them,  since  it  is  no  longer  assisted  by  the  right  ventricle  through  the  ductus  Botalli. 
Also,  cold  contracts  the  arteries,  which  have  a  powerful  nuiscular  coat.  The  pulsa- 
tion in  the  cord  ceases.  Since  the  pressure  in  the  right  auricle  is  low  and  that  in  the 
left  higher,  the  valve  of  the  foramen  ovale  applies  itself  to  the  septum  auriculorum. 
and  thus  the  two  sides  of  the  heart  become  distinct. 

The  circulation  is  now  just  the  same  as  in  the  adult.  The  ductus  Arantii  and 
ductus  Botalli  grow  smaller  by  contraction  of  their  muscular  fillers  and  the  applica- 
tion of  their  walls  to  each  other.  No  thrombosis  occurs  in  them,  nor  in  the  vein  of  the 
umbilical  cord— only  in  the  arteries.     They  become  obliterated  in  one  or  two  weeks.

The  Plastic  Changes  Wrought  on  the  Fetus. — The  conditions  during  labor  are 
unlike  those  enjoyed  by  the  child  during  pregnancy.  The  contracting  uterus  com- 
presses the  fetus  into  a  definite  shape,  and  gives  it  a  certain  attitude,  both  of  which 


Fig.    163. — Rear   View   op   Skull   Molded   in   O.L.A. 


are  to  facilitate  its  passage  through  the  parturient  canal.  The  legs  are  flexed  on  the 
thighs  and  crossed  over  each  other,  the  thighs  on  the  abdomen;  the  arms  are  folded 
across  the  chest,  the  head  flexed  so  that  the  chin  rests  on  the  sternum  (Fig.  160). 


Fig.   KU. — Side  View  of  Skdll  Molded  in  O.L.A. 


The  pressure  of  the  uterus  on  the  crossed  legs  may  bend  the  tibia  and  fibula,  but  the 
deformity  lasts  only  a  week  or  more. 

The  head  undergoes  marked  changes,  which  vary  with  the  presentation  of  the 
child  for  delivery,  and  are  caused  by  pressure  exerted  by  the  maternal  structures. 


THE    EFFECT    OF    LABOR    ON    THE    CHILD  S    ORGANISM 


143 


In  ordinary  head  presentations,  with  a  moderately  tight  parturient  passage,  the  face 
and  the  forehead  are  flattened,  the  occiput  long  drawn  out  (Fig.  1G2),  the  bones 
overlapped.  Usually  the  occipital  l)one  is  pressed  under  the  two  parietals — the 
frontal  also  somewhat  below  them.  One  parietal  overlaps  the  other,  the  one  that 
lies  against  the  promontory  being  the  one  that  is  depressed  (Figs.  1G3  and  164).  The 
head  offers  thus  a  long  narrow  cylinder  to  the  birth-canal,  instead  of  a  round  ball. 
These  changes  in  shape,  or  "molding,"  are  possible  because  of  the  softness  of  the 
bones  and  the  loose  connection  they  have  with  each  other  at  the  sutures.  When 
this  molding  is  absent,  labor  is  more  difficult.  Some  slight  diminution  in  the  size  of 
the  head  occurs  in  labor,  especially  if  the  p(4vis  is  contracted,  and  it  is  due  to  the 
escape,  under  pressure,  of  the  cerebrospinal  fluid  into  the  spinal  canal.  Necessarily, 
it  is  small  and  cuts  little  figure  in  the  mechanism  of  delivery. 

Along  the  sutures  it  is  not  uncommon  to  find  numerous  small  hemorrhages  in 
and  under  the  dura  mater  and  under  the  external  periosteum.     They  are  due  to  the 


Fig.  165. — Epidural  Hemorrhages  Along  Longitudinal  .Sixrs 


overlapping  of  the  bones,  and  are  most  marked  in  cases  where  the  head  has  been 
forced  through  a  narrow  pelvis  or  compressed  by  the  forceps  (Fig.  165).  On  that 
part  of  the  head  least  sulijected  to  pressure  there  appears  in  long  labors  a  soft,  boggy, 
circumscribed  tumor.  In  vertex  presentations  it  is  formed  on  one  parietal  ])one.  It 
is  caused  by  the  pressure  of  the  uterus  on  the  body  of  the  child  being  greater  than 
that  on  the  portion  which  lies  below  the  girdle  of  resistance — that  is,  through  the 
opening  in  the  cervix  or  the  vagina,  or  even  in  the  vulva  (Fig.  166).  The  action  is 
similar  to  that  occurring  in  a  limb  tightly  gartered — the  ]>lood  cannot  return;  venous 
congestion  with  edema  and  extravasation  of  blood  results.  These  small  hemor- 
rhages persist  long  after  the  edema  is  absorbed,  and  mark  the  site  of  the  tumor  on 
the  head.  The  swelling  is  called  caput  succedaneum,  and  it  occurs  in  and  under 
the  scalp,  not  under  the  periosteum,  in  ordinary  cases.  It  is,  therefore,  movable  on 
the  skull.  It  may  sag  toward  the  side  on  which  the  child  lies  after  delivery,  but  the 
blood  extravasations  will  not  change.  If  the  pressure  has  been  prolonged,  the 
hemorrhagic  infiltration  affects  the  periosteum,  the  bone,  and  corresponding  regions 


144 


PHYSIOLOGY   OF   LABOR 


of  the  meninges.  A  caput  succedaneuni  can  form  Ijefore  the  bag  of  waters  breaks 
because  the  pressure  in  the  bag  is  less  than  that  in  the  general  uterine  cavity,  but  it 
is  rare.  Most  commonly  we  find  the  largest  caput  in  a  contracted  pelvis  with  pro- 
longed and  powerful  pains,  and,  second,  when  the  head  is  arrested  at  the  bony  outlet. 
In  either  of  these  cases,  but  especially  in  the  latter  instance,  the  caput  may  be  visible 
at  the  vulva.  It  may  make  the  attendant  believe  that  the  labor  is  advancing,  when 
in  reality  the  growing  caput  indicates  that  the  head  has  met  an  obstruction  (Fig. 
167).  Thus  it  may  give  warning  of  the  necessity  to  interfere  in  labor.  One  must 
distinguish  between  caput  succedaneum  and  cephalhematoma,  which  is  an  accumu- 
lation of  blood  under  the  periosteum.     (See  Chapter  LXII.) 

The  caput  exaggerates  the  obliquity  of  the  head  produced  by  the  depression  of 
the  parietal  bone  by  the  promontory  of  the  sacrum  or  the  pelvic  floor.     (See  Figs. 


Fig.  166. — Showing  How  a  Caput  is  Formed. 


163  and  164.)  The  caput  is  absorbed  in  twenty-four  to  thirty-six  hours;  the  asym- 
metry of  the  head  produced  by  the  mechanical  factors  in  labor  disappears  by  the 
end  of  a  week,  ])ut  there  often  remains  a  permanent  asymmetrj^  of  the  skull,  called 
that  of  Stadtfelcl,  who  first  described  it.  All  forms  of  growth  have  a  slightly  spiral 
direction.  This  is  true  also  of  the  fetus.  There  is  a  congenital  scoliosis  of  the 
spinal  column.  The  right  parietal  bone  is  pushed  anteriorly  in  a  horizontal  plane, 
appearing  flat,  while  the  left  is  more  convex.  This  asymmetry  is  permanent  and 
has  been  demonstrated  in  the  adult.  The  head  tracings  to  be  seen  in  any  hat-shop 
show  it.  While  the  right  side  is  usually  affected,  the  twisting  may  be  reversed. 
The  asymmetry  of  Stadtfeld  may  be  counteracted  by  the  molding  produced  during 
labor.  After  the  latter  disappears,  the  true  shape  of  the  skull  returns.  In  primi- 
parse  long  compression  of  the  head  by  the  lower  uterine  segment  and  pelvis  results 
in  dolichocephalus,  which  may  be  permanent. 


THE   EFFECT    OF   LABOR   ON   THE    CHILD's   ORGANISM  145 

In  breech  presentations  the  head  may  be  flattened  by  the  pressure  of  the  fundus 
against  it  for  a  long  time.  In  a  tightly  built  primipara  the  flattening  may  begin  in 
the  latter  months  of  pregnancy  and  may  be  permanent.  Sometimes  corresponding 
shortening  of  the  sternocleidomastoid  muscle  results  from  the  strained  attitude  of 
the  child,  and  wry-neck  is  produced. 

Without  doubt  labor  affects  the  fetus  in  more  ways  than  our  present  means  of 


Fia.   107. — Large  Caput  Succedaneum  Showing  Hemorrhages  Into  Skin. 

investigation  disclose.  Perhaps  tiny  hemorrhages  in  the  brain  may  ex])lain  some 
of  the  so-called  congenital  deformities  and  diseases,  for  instance,  strabismus,  ptosis 
palpebrarum,  epilepsy,  persistent  headache,  idiocy. 


THE  PROGNOSIS  OF  LABOR 

In  ideal  labor  there  should  be  no  mortality  of  either  mother  or  child,  but,  un- 
fortunately, we  are  far  from  this  ideal. 

In  the  United  States  of  America,  from  a  registered  area  of  a  little  more  than  one- 
half  of  the  total  area  of  the  country,  over  8000  women  die  annually  in  childbu'th. 
(See  table  below.)      The  number  seems  to  be  gro\ving  all  the  time. 

The  increase  year  by  year  is  explained  by  the  increasing  area  of  registration 
and  the  improvement  in  the  statistical  reports.  Without  doubt  several  thousand 
women  die  in  childbirth  every  year  and  are  buried  under  another  diagnosis.  Hun- 
dreds die  months  and  even  years  after,  but,  nevertheless,  from  the  direct  results  of 
labor,  from  their  injuries,  from  infection,  and  from  operations  undertaken  to  cure 
them.  Then,  too,  the  given  statistics  cover  only  half  of  the  area  of  the  country, 
though  the  most  densely  populated  portion.

These  figures  are  incomplete  because  the  birth  of  still-born  infants  is  not  recorded,  and  the 
mortality  of  the  mothers  following  such  births  is  not  included. 

In  Norway  (Dreyer)  the  mortality  in  1904  was  2.8  per  thousand,  an  improve- 
ment over  1870,  when  it  was  7  per  thousand. 

If  all  deaths  were  reported,  the  mortality  tables  would  be  still  more  alarming. 
At  present  it  is  safe  to  say  that  of  every  200  women  who  l^ecome  pregnant,  one  dies 
before  the  reproductive  function  is  completed. 

In  speaking  of  these  deaths  we  must  distinguish  between  the  preventable  and 
the  unavoidable.  Without  question  the  mortality  of  childbirth  could  be  reduced 
to  one  per  thousand  if  the  public  were  properly  instructed  regarding  the  needful  pre- 
cautions, and  if  the  plwsicians  were  all  capable  of  meeting  obstetric  emergencies, 
and,  most  important,  practised  an  aseptic  technic.  It  will  be  noticed  in  all  the 
statistics  that  nearly  half  the  deaths  were  from  infection. 

There  is  an  unavoidable  mortalitj^  in  childbirth,  and  it  comes  from  disease  of 
the  uterus,  adnexa,  and  pelvis,  and  from  general  affections  aggravated  by  parturi- 
tion, but  it  is  small  compared  with  the  prevent aljle  mortality. 

Labor  shows  a  high  morbidity,  that  is,  the  women  are  sickened  or  injured  in 
the  process  of  reproduction.  The  author  has  never  seen  a  woman  as  anatomically 
perfect  after  delivery  as  she  was  before  pregnancy  occurred.  Many  women  date 
life-long  invalidism  from  a  confinement.  Overdistention  of  the  abdomen  often 
leaves  weakness  of  the  abdominal  wall  and  visceroptosis;  the  urogenital  septum  is 
always  torn,  and  prolapse  of  the  urethra  and  anterior  vaginal  wall  occurs,  the  patu- 
lous vulva  opening  the  way  for  infectious  catarrhs  of  the  bladder  and  of  the  cervix 
and  chronic  metritis;  laceration  or  overstretching  of  the  pelvic  floor  is  an  almost 
invariable  occurrence  in  greater  or  less  degree,  inviting  prolapse  of  the  uterus — 
these  are  some  of  the  inevitable  consequences  of  labor.  If  to  these  be  added  the 
frequent  infections  of  the  uterus  and  adnexa,  the  damage  to  the  soft  parts  from 
operative  deliveries,  disease  of  the  kidneys,  of  the  liver,  etc.,  one  quickly  appreciates 

*  Owing  to  changes  in  classification  for  the  year  1910,  these  figures  may  not  be  compared 
with  those  of  previous  years.

the  high  morbidity  of  the  reproductive  function  in  the  human  female  in  our  day. 
Naturally,  it  is  impossible  to  compile  statistics  as  to  the  freciuenc}'  of  these  affections, 
but  the  records  of  the  hospitals  show  a  continual  stream  of  women  seeking  relief 
from  the  bad  effects  of  childbirth.  Most  of  these  diseases  and  accidents  can,  even 
vnth  our  present  knowledge,  be  prevented,  and  no  field  in  all  preventive  medicine 
promises  greater  results. 

Prognosis  for  the  Infant. — The  highest  mortality  that  befalls  the  human  race 
in  one  day  occurs  on  the  da}'  of  birth.  Schultze  estimates  that  5  per  cent,  of  chil- 
dren are  still-born,  dying  during  labor,  and  1.5  per  cent,  die  shortly  after  birth,  the 
result  of  the  trauma  of  labor.  Brothers  found  that  in  New  York  city,  in  the  four 
years  from  1889  to  1892,  over  16,000  children  were  born  dead  or  died  iimnediately 
after  labor.  In  Chicago  about  2000  children  cUe  annually  from  birth  accidents 
(Evaixs).  In  Paris  9  per  cent.  die.  It  is  safe  to  say  that  in  the  United  States 
75,000  children  die  annually  during  delivery.  Asphj^cia  and  injury  during  labor 
are  frequent  causes  of  fetal  death,  but  a  large  part  of  the  mortality  is  due  to  con- 
genital defects,  s\^philis,  alcoholism  of  the  parents,  and  general  diseases. 

Besides  this  mortality,  the  children  are  frequently  injured  during  delivery, 
either  by  the  natural  powers  or,  and  more  often,  by  operative  procedure.  Hemor- 
rhages into  the  brain,  tentorium  tears,  fracture  of  the  skull,  dislocation  and  fracture 
of  the  vertebrae,  joints,  and  extremities,  often  result  from  the  brutal  deliveries  ren- 
dered necessary  in  cases  of  mechanical  disproportion.  ^Milder  injuries  of  brain, 
nerves,  and  bones  are  very  frequent,  but  are  often  overlooked  until  their  later 
eflfects  become  prominent;  for  example,  Little's  disease  from  injury  to  the  brain  and 
spinal  cord,  chronic  hydrocephalus,  athetosis,  idiocy,  etc. 

One  such  brief  glance  into  the  sul^ject  will  show  the  immensity  of  this  field  of 
preventive  medicine,  and  prove  to  the  reader  that  obstetrics  is  not  one  of  the  minor 
branches  of  medicine,  but  a  specialty  deserving  the  attention  of  the  best  minds  in 
the  profession.

CHAPTER  IX 

THE  MECHANISM  OF  LABOR 

The  details  of  the  wonderful  process  of  parturition,  whose  clinical  manifesta- 
tions we  have  just  considered,  deserve  separate  study.  The  mode  and  manner  by 
which  the  ovum  is  separated  and  extruded  from  the  uterus  comprise  the  mechanism 
of  labor,  and  deserve  the  closest  attention  of  the  practising  obstetrician.     Indeed, 


Fig.   168. — Internal  Uterine  Pressure  (I.U.P.).     Effect  of  Uterine  Contraction. 


without  accurate  knowledge  of  this  mechanism  he  ceases  to  be  a  scientific  practi- 
tioner and  becomes  a  midwife.  The  accoucheur  who  knows  the  science  of  the 
mechanism  of  labor  will  early  recognize  deviations  from  the  normal,  and,  by  some 
simple,  harmless  manipulation,  may  direct  the  course  of  labor  into  the  normal  again. 
He  also  will  be  able  to  deal  with  the  pathologic  mechanisms  with  the  least  possible 
danger  of  injury  to  the  mother  and  child.     The  ignorant  accoucheur,  on  the  other

hand,  will  allow  the  labor  to  go  on  until  positive  obstruction  exists  and  the  hves  of 
parent  and  child  are  placed  in  jeopardy.  Then  he  must  use  brute  force  to  overcome 
mechanical  difficulty,  with  the  almost  invariable  result  of  severe  maternal  injury 
and  frequent  destruction  of  the  child.  Although  a  daily  occurrence,  and  the  object 
of  a  century  of  study  by  the  most  eminent  accoucheurs,  the  intricate  processes  of 
parturition  are  not  all  understood,  and  many  of  them  are  not  yet  satisfactorily 
explained. 

The  subject  falls  naturally  into  the  consideration  of  three  factors:    first,  the 
poicers;   second,  the  passages;   third,  the  passengers.     After  this  the  action  of  the 


Fig.  169. — Action  of  the  Uterine  Ligaments. 


powers  on  the  passengers  in  forcing  them  through  the  prepared  passages  must  be 
studied. 

The  Powers. — The  uterus  is  the  main  driving  engine,  with  the  al)dominal 
muscles  as  a  powerful  auxiliary.  Gravity,  that  is,  the  weight  of  the  child,  is  of 
small  influence,  while  the  elastic  contraction  of  the  vagina  and  iierineal  floor  has 
hardly  anj-  effect  on  the  propulsion  of  the  ovum. 

AVhen  the  uterus  contracts,  it  exerts  equal  pressure  on  its  contents  in  all  direc- 
tions, obejdng  the  law  of  pressure  on  fluids.  If  the  pressure  were  met  all  over  by 
equal  resistances,  it  would  return  to  the  uterine  wall  nullified,  but  since  there  is  a 
weak  spot  in  the  uterine  wall,  the  lower  uterine  segment  and  internal  os.  the  contents 
of  the  uterus  will  all  be  forced  in  this  direction.     The  resultants  of  all  the  forces 


150 


PHYSIOLOGY   OF   LABOR 


applied  to  the  bodies  in  the  uterus  will  point  toward  the  internal  os  (Fig.  168). 
This  hydraulic  pressure  is  the  most  important  factor  in  the  work  of  the  uterus,  but 
other  factors  have  been  invoked.  Lahs  and  Schatz  believed  that  the  uterus,  com- 
pressing the  fetus  from  side  to  side,  lengthened  its  spinal  column,  forcing  the  breech 
against  the  fundus  and  the  head  dowmward  into  the  pelvis.  This  pressure  is  called 
the  fetal  axis  pressure,  and  is  absent  in  polyhydramnion,  and  with  a  small  or  macer- 
ated fetus.  The  change  of  the  C-formed  spinal  column  to  the  straighter  form  results 
in  a  lengthening  of  the  fetal  cylinder  of  10  cm.     Whether  the  uterus  presses  on  the 


Fig.  170. — Action  of  the  Intra-abdominal  Pressure  in  Augmenting  Intra-uterine  Pressure. 
Girdles  of  resistance  indicated  by  white  lines. 


pelvic  extremity  of  the  fetal  axis  and  thus  causes  an  advance  of  the  child  or  not  is 
still  a  disputed  question,  with  the  decision  probably  in  the  negative. 

Intra-uterine  pressure  accomplishes — (1)  The  protrusion  of  the  bag  of  waters; 
(2)  the  dilatation  of  the  lower  uterine  segment  and  cervix;  (3)  it  causes  edema  and 
succulence  of  the  soft  parts — the  so-called  "vital  dilatation";  (4)  the  expulsion  of 
the  fetus  and  placenta. 

The  round,  the  uterosacral,  and  the  broad  ligaments  have  important  func- 
tions. They  are  part  of  the  uterus, — mere  extensions  of  its  muscle-fibers, — 
and  contract  when  it  contracts.     These  bands  serve  to  moor  the  uterus  to  the 


THE    MECHANISM    OF   LABOR  151 

pelvis  and  prevent  too  great  retraction  al)Ove  the  ehild.  Tlie  round  ligaments 
pull  the  fundus  forward  and  ])ring  its  axis  parallel  with  the  axis  of  the  inlet  (Fig. 
169).  The  uterosacral  ligaments  pull  the  cervix  backward  and  downward  and  also 
help  open  up  the  lower  uterine  segment  and  upper  cervix.  All  the  ligaments,  l^y 
the  force  exerted,  increase  the  intra-uterine  pressure  and  help  expel  the  fetus. 

The  abdominal  jiressure  is  a  powerful  auxiliary  in  labor,  and  maj'  substitute 
the  uterine  contraction  more  or  less  completely.  During  the  first  stage  the  ab- 
dominal muscles  do  not,  and  should  not,  take  any  part  in  the  process  of  labor,  but 
in  the  second  stage  they  are  called  upon  to  assist  and  complete  the  work  of  the 
uterine  contractions.  During  an  expulsive  pain  the  woman  closes  the  glottis  and 
makes  a  powerful  Ijearing-down  effort.  She  forces  down  the  diaphragm  and  con- 
tracts the  recti,  the  obliqui,  and  the  muscles  of  the  flanks.  There  is  now  a  great 
increase  of  the  intra-abdominal  pressure,  which,  obeying  the  law,  is  transmitted 
equally  in  all  directions,  the  uterus  receiving  its  share.  It  is  easy  to  see  how  the 
abdominal  pressure  is  simply  added  to  the  intra-uterine  pressure,  resulting  in  in- 
creased general  intra-uterine  pressure  (Fig.  170). 

After  the  dilatation  of  the  cervix  the  abdominal  muscles  alone  are  able  to  expel 
the  child,  and  usually  do  it,  since  the  uterus  by  this  time  has  retracted  so  high  over 
the  fetal  cylinder  and  its  muscle-fibers  are  so  shortened  that  it  has  verj'  little  ex- 
pulsive power. 

In  pathologic  labor  the  abdominal  muscles  are  particularly  useful  in  overcom- 
ing the  abnormal  resistances,  in  preventing  uterine  rupture  by  restraining  the  up- 
ward displacement  of  the  uterus,  and  in  other  ways.  In  the  third  stage  of  labor  the 
placenta  is  expelled  by  the  exertions  of  the  abdominal  wall,  but  only  after  the  pla- 
centa is  separated  and  lies  in  the  lower  uterine  segment  and  vagina. 

The  power  of  the  uterine  contraction  cannot  be  accurately  measured.  Duncan 
tried  to  do  it  by  testing  the  resistance  of  the  fetal  membranes.  The  force  necessary 
to  rupture  them  varies  greatly.  Schatz,  with  his  tokodynamometer,  a  rubl)er  ])ag 
half  filled  with  water,  lying  in  the  uterus,  connected  with  a  manometer,  found  that 
the  uterine  contraction  during  the  first  stage  showed  a  pressure  of  from  17  to  55 
pounds,  and  during  the  second  stage,  when  the  force  of  the  abdominal  muscles  was 
added,  it  was  about  doubled.  Clinically,  the  power  of  the  uterine  contraction  may 
often  be  appreciated.  It  may  crush  the  baby's  head  or  fracture  its  bones.  The 
accoucheur's  hand  in  the  uterus  may  be  squeezed  so  hard  that  it  ])ecomes  insensil)le 
and  paralyzed.  In  rare  cases  tumultuous  action  of  the  uterus  and  abdominal 
muscles  may  eject  the  infant  from  the  vulva  with  much  force.  Probably  the  or- 
dinary amount  of  force  exerted  by  the  uterus  and  abdomen  rarely  exceeds  30  pounds. 

Gravity  plays  but  a  small  role  in  labor.  The  difference  in  specific  gravity  of 
the  fetus  and  its  liquor  amnii  is  not  great.  The  constant  slight  pressure  exerted  by 
the  head  on  the  lower  uterine  segment  may  soften  this  portion  of  the  uterus,  or  it 
may  elicit  stronger  pains.  One  often  observes  that  a  change  of  the  parturient's 
position,  which  l^rings  the  weight  of  the  fetus  onto  the  cervix,  such  as  walking  or 
sitting  up,  will  strengthen  the  uterine  contractions. 


CHAPTER  X 

THE  PASSAGES 

The  fetus  has  to  traverse  a  bent  passage,  which  is  partly  bony  and  partly 
fibrous  and  muscular.  The  bony  portion  is  the  pelvis,  which  is  divided  into  two 
parts  by  a  ridge  called  the  linea  terminalis.  The  upper,  large,  or  false  pelvis  is  of 
little  obstetric  interest.  It  is  made  up  of  the  flaring  iliac  plates  at  the  sides,  the 
spine  behind,  and  the  gap  in  front  over  the  pubis  is  filled  in  by  strong  abdominal

muscles.  The  false  or  upper  pelvis  is  shaped  like  a  flat  funnel,  and  forms  a  support 
for  the  uterus  and  child  during  pregnancy,  directing  the  latter  into  the  true  pelvis 
at  the  proper  time.  The  shape  and  size  of  the  false  pelvis,  too,  give  the  obstetrician 
some  conception  of  the  shape  and  size  of  the  true  pelvis.  (See  p.  234.)  The 
true,  lower,  or  small  pelvis  (pelvis  minor)  is  of  immense  obstetric  importance,  since 
it  supports  the  muscles  of  the  pelvic  floor  and  gives  shape  and  direction  to  the  par-

turient  canal,  itself  forming  part  of  same.  A  plaster  cast  of  a  true  pelvis,  as  first 
made  by  Hodge,  shows  its  cavity  to  have  the  shape  of  a  cylinder  with  a  bluntly 
pointed  exaxial  lower  end.  It  is  very  slightly  curved  anteriorly.  The  entrance 
and  outlet  of  the  true  pelvis  are  smaller  than  the  middle  portion,  and  have,  therefore, 
been  called  straits — the  superior  and  inferior.  The  region  between,  being  large  and 
roomy,  is  called  the  excavation.  Anteriorly,  the  canal  is  short — 4}/^  cm. ;  posteriorly, 
long,  the  length  of  the  sacrum — 121^  cm.  Laterally,  the  pelvic  canal  is  longer,  and 
the  sides  narrow  slightly  from  above  downward,  especially  behind,  near  the  spines 
of  the  ischia,  but  broadening  out  below  at  the  tuberosities.  The  contour  of  the 
canal,  therefore,  varies  much  at  different  levels,  and  it  is  customary  to  d('scril)e  these 
variations  by  means  of  planes  drawn  more  or  less  arbitrarily  through  the  pelvis. 
It  must  l)e  clearly  understood  that  the  so-called  planes  about  to  be  described  are

really  not  such  in  a  mathematic  sense,  but  represent  regions  or  portions  of  the  pelvis, 
and  have  three  dimensions. 

The  plane  of  the  inlet,  brim,  superior  strait,  isthmus,  margin,  or  apertura  pelvis 
superior,  is  bounded  by  the  upper  border  of  the  pubis  in  front,  the  linea  innominata 
or  linea  terminalis  at  the  sides,  and  the  sacral  promontory  behind  (Fig.  172).  This 
plane  is  heart-shaped — that  is,  a  transverse  ellipse  on  which  the  sacrum  intrudes 
behind.  The  depth  of  the  region  of  the  inlet  is  about  2  cm.,  and  represents  the 
distance  from  a  line  drawn  in  the  pubosacral  diameter  to  a  transverse  line  in  the 
lowest  level  of  the  Unea  terminalis.  (See  Fig.  173.)  It  is  deeper  behind  than  near 
the  pubis,  and  varies  very  much  in  all  three  dimensions — that  is,  in  shai)e  and  depth. 
(For  detailed  description  see  chapter  on  Contracted  Pelvis.)  The  inlet  is  a 
very  important  region  of  the  pelvis,  because  contraction  and  distortion  of  the  bones, 
due  to  disease,  are  likely  to  l)e  marked  here,  and,  further,  it  is  an  imjjortant  factor  in 
normal  labor.  Its  diameters  are,  first,  the  anteroposterior,  i^ulwsacral,  or  conjugata 
vera  (C.  V.),  named  by  von  Roederer,  extending  from  the  top  of  the  pubis  to  the 


154 


PHYSIOLOGY   OF   LABOR 


tip  of  the  sacral  promontory,  measuring  113  2  cm.  This  is  the  true  or  anatomic 
conjugate.  The  shortest  anteroposterior  cUameter  is  from  a  point  1  cm.  lower  on 
the  surface  of  the  pubis  to  the  promontory,  and  is  called  the  obstetric  conjugate 
(Michaelis),  because  intimately  concerned  in  the  mechanism  of  labor,  especially  in 
contracted  pelves.  It  measures  11  cm.  in  the  normal  pelvis,  but  may  be  reduced  to 
a  few  centimeters  in  abnormal  pelves.  When  we  speak  of  a  pelvis  of  8  cm.  we 
mean  one  wdth  a  C.  V.  of  8  cm.  It  is  impossible  satisfactorily  to  measure  the  C.  V. 
on  the  living,  though  numerous  instruments  are  vaunted  for  the  purpose.  We  can 
gather  an  approximately  correct  idea  of  its  length  from  the  measurement  of  the 
distance  from  the  under  margin  of  the  pubis  to  the  promontory.     This  diameter  is 


Fig.  173. — The  Regions  op  the  Pelvis. 


called  the  conjugata  diagonalis  (C.  D.),  and  is,  in  normal  pelves,  about  1}4.  cm. 
longer  than  the  C.  V.,  that  is,  about  123^^  cm.  (See  Pelvimetry,  p.  238.)  Trans- 
versely, the  inlet  measures  13  cm.,  while  the  two  obliques  measure  12  and  123^2  re- 
spectively. The  oblique  diameters  are  named  first  and  second,  or,  better,  right  and 
left,  using  the  sacro-iliac  joints  as  the  denominator,  according  to  the  recommenda- 
tion voted  at  the  Congress  at  Washington  in  1887  (Bar).  The  right  oblique  extends 
from  the  right  sacro-iliac  joint  to  the  left  iliopubic  tubercle;  the  left,  between  cor- 
responding points.  They  are  important  diameters,  because  the  head  usually  enters 
the  pelvis  in  one  or  the  other.  Since  most  individuals  step  harder  on  the  right  foot, 
and  since  they  also  have  a  slight  right  scoliosis,  the  right  half  of  the  pelvis  is  a  bit 
flattened,  and  the  left  oblique,  therefore  a  trifle  shorter  than  the  right.     The  inlet

is  encroached  upon  by  the  ihopsoas  muscles  (Fig.  175),  ])ut  probably  not  enough 
usually  to  disturlj  the  mechanism  of  labor.  If  the  child  should  be  large  and  the 
muscle  well  developed,  the  muscle  might  delay  the  engagement  of  the  head.  Pos- 
ture to  relax  the  muscle  would  reheve  the  obstruction. 

The  wide  pelvic  plane  is  one  passing  from  the  middle  of  the  pubis  to  the  junc- 
tion of  the  second  and  third  sacral  vertebra)  (Fig.  176).  It  is  about  the  center  of 
the  region  called  the  ''excavation"  of  the  pelvis,  and  is,  therefore,  sometimes  called 
the  midplane,  this  latter  term  being  much  used  in  operative  obstetrics.     This  plane

is  irregularly  ovoid,  occupying  the  roomiest  portion  of  the  pelvis,  and  with  an 
anteroposterior  diameter  of  IS^  2  cm-  and  a  transverse  of  12}  2  cm. 

The  narrow  pelvic  plane  passes  through  the  apex  of  the  pubic  arch,  the  spines 
of  the  ischia,  and  the  end  of  the  sacrum  (Fig.  177).  This  is  the  smallest  strait  of 
the  pelvis,  and  is  frequently  the  site  of  contracture,  a  fact  which  is  only  lateh'  being 
adequately  appreciated.  This  plane  is  ovoid,  with  the  large  end  anteriorly  and  the 
smaller  end  behind,  formed  l)y  the  sacrosciatic  ligaments.  Owing  to  the  incurvation 
of  the  spines  of  the  ischia  and  the  attachments  of  the  levator  ani  muscle  and  fascia 
the  child,  in  its  passage,  is  crowded  into  the  anterior  portion  of  this  plane.  Its  most 
important  diameter  is  that  between  the  spines — 10}  2  cn^-  An  imaginary  line  dra^^^l 
between  the  spines  of  the  ischia  is  used  to  fletermine  the  descent  of  the  head  into 
the  pelvis.  The  narrow  pelvic  plane  is  important  also  because  it  is  the  beginning 
of  the  bend  of  the  cylindric  birth-canal.     In  labor,  the  head  descends  straight  into 


156 


PHYSIOLOGY    OF   LABOR 


the  pelvis  until  it  reaches  this  plane,  then  begins  to  rotate  and  slide  forward  under 
the  pubis. 

The  plane  of  the  outlet  passes  through  the  arch  of  the  pubis,  the  rami  of  the 
pubes,  the  tuberosities,  and  the  tip  of  the  coccyx.  This  plane  is  the  lower  boundary 
of  the  region  of  the  bony  outlet,  and  is  not  seldom  the  seat  of  contracture.  There 
are  really  two  planes,  roughly  resembling  triangles  bent  at  their  applied  bases  on  the 
tuberosities.  During  labor  the  head  pushes  the  coccjtc  back  (Fig.  174),  bringing 
the  two  parts  more  into  one  plane,  and  at  the  same  time  increasing  the  antero- 
posterior diameter  from  93/^  to  12  em.  The  transverse  diameter  of  this  plane  is 
important — 11  cm. 

The  above  is  a  description  of  the  classic  pelvic  planes  dating  from  the  time  of

Levret  (1770).  Hodge,  of  Philadelphia,  constructed  a  series  of  more  arbitrary 
planes,  all  running  parallel  to  the  inlet  (Fig.  179).  The  first  parallel  is  in  the  inlet; 
the  second  parallel,  called  by  Veit  the  "chief  plane,"  touches  the  arch  of  the  pubis 
and  strikes  the  lower  part  of  the  second  sacral  vertebra;  the  third  cuts  the  spines  of 
the  ischia,  and  the  fourth  goes  through  the  tip  of  the  coccyx  and  represents  the 
pelvic  floor.  The  Hodge  system  never  obtained  general  recognition,  and  one  mod- 
ern author  calls  it  obsolete,  but  Sellheim,  to  whom  we  owe  much  in  the  study  of  the 
mechanism  of  labor,  recently  (1909)  declared  it  the  only  scientific  method  for  the 
study  of  the  pelvis  and  the  mechanism  of  labor,  and  recommended  its  general  adop- 
tion by  teachers  and  writers.     It  is  a  fact  that  the  head  enters  the  pelvis  in  the  axis 


THE    PASSAGES 


157 


of  the  inlet,  passing  successively  through  these  planes,  and,  too,  since  we  can  easily 
determine  the  location  and  direction  of  the  inlet,  it  is  a  simple  matter  to  orient 
one's  self  as  to  the  location  of  the  planes  parallel  to  it.  The  author  has  used  the 
Hodge  system  of  planes  in  his  studies  of  the  mechanism  of  labor,  and  agrees  with 
Sellheim  as  to  their  scientific  worth.  In  the  comparative  study  of  contracted  pelves 
(Hegar)  and  in  gynecologic  diagnosis  they  are  equally  valuable. 


Fig.  176. — Wide  Pelvic  Plane. 

When  tlie  woman  is  in  the  erect  position,  the  inlet  makes  an  angle  of  about  55 
degrees  Avith  the  horizon,  but  this  varies  from  40  degrees  to  100  degrees,  depending 
on  the  rotation  of  the  thighs  and  the  carriage  of  the  shoulders.  This  is  called  the 
inclinatio  pelvis.  A  quick  method  to  determine  if  this  inclination  of  the  pelvis  is 
normal  is  to  see  if  the  anterosuperior  spine  of  the  ilium  and  the  pubis  are  in  a 
vertical  plane.     In  the  lying  position  the  inlet  is  25  degrees  below  the  horizontal. 


Fig.   177. — Narrow  Pelvic  Pl.vne. 


The  cre-sts  of  the  ilium  run  about  parallel  to  the  plane  of  the  inlet.  Formerly,  great 
importance  was  attached  to  the  pelvic  inclination  as  affecting  the  mechanism  of 
labor,  lately  not  much. 

Contrary  to  what  would  l^e  expected,  the  pelvis  is  not  a  solid  and  fixed  bony 
structure.  The  coccyx  is  easily  pressed  back  by  the  advancing  head,  enlarging  the 
outlet  2  to  2.5  cm.     The  pelvic  joints  are  fixed  by  strong  ligaments,  but  during 


158 


PHYSIOLOGY   OF   LABOR 


pregnancy  these  soften  and  allow  a  certain  degree  of  mobility  to  the  bones.     While 
they  do  not  permit  much  actual  enlargement  of  the  pelvic  cavity,  as  believed  the

ancients,  and  as  occurs  in  many  animals,  the  loosening  of  the  joints  allows  the  hip 
bones  to  rotate  on  the  sacrum  when  the  body  is  bent  into  forced  extension  and  flexion. 
Thus,  the  sacrum  being  fixed,  the  pubis  moves  downward  in  forced  extension  of

the  thighs, — Walcher's  position, — enlarging  the  inlet  by  0.5  to  1  cm.  (Fig.  180).  In 
forced  flexion,  the  knees  being  pressed  against  the  abdomen,  the  pubis  is  forced 
up,  the  ossa  innominata  rotate  upward  and  dip  outward,  enlarging  the  outlet  of 
the  pelvis.  These  changes  in  the  shape  of  the  pelvis  are  made  use  of  in  the  con- 
duct of  labor.     (See  Chapter  LVIII.)

THE  SOFT  PARTS 

Fig.  175  shows  the  relation  of  the  psoas  and  iliacus  muscles  to  the  inlet.  It  will 
be  seen  that  they  give  it  a  more  quadrangular  shape;  that  they  encroach  but  little 
on  its  lumen;  and  that  only  in  cases  of  transversely  contracted  pelves  will  they  in- 
terfere in  the  mechanism  of  labor.  The  rectum  lies  on  the  left  side  behind,  and  i^ro- 
jects  into  the  cavity  only  when  filled.  It  may  thus  cause  dystocia.  The  midplane 
is  encroached  on  by  the  obturator  internus  and  behind  by  the  pjTiformis — very 
shghtly,  however.  The  nerves  in  the  pelvis  make  no  obstruction,  antl,  owing  to  the 
projecting  spines  of  the  ischia  and  the  forward  dip  of  the  pelvic  floor,  rarely  are 
subject  to  pressure.  When  they  do  suffer  pressure,  the  parturient  has  pains  running 
down  the  legs  and  up  the  back.  The  peritoneum  and  fat  count  very  little  in  the 
general  configuration  of  the  parturient  canal,  as  was  proved  by  Hodge  with  plaster 
casts.

PHYSIOLOGY   OF   LABOR 


The  cervix  and  the  lower  uterine  segment  have  already  been  considered.  Of 
most  obstetric  interest  is  the  pelvic  floor.  This  consists  of  those  soft  tissues  which 
fill  out  the  irregularly  shaped  outlet  of  the  pelvis.  A  great  many  structures  enter 
into  its  formation — the  pelvic  fascia,  the  levator  ani  and  coccygeus,  the  deep  and 
superficial  transverse  perineal  muscles,  the  constrictor  cunni,  the  urogenital  septum, 
fat  and  skin,  and  the  organs — rectum,  vagina,  and  urethra.  Careful  dissection  and 
embryologic  study  enable  us  to  distinguish  two  diaphragms  in  the  pelvic  floor  (Holl) 
— an  upper  stronger,  a  muscular  system,  modified  from  that  formerly  used  for  the 
tail,  and  a  lower,  weaker,  developed  from  the  sphincter  cloacae,  w^hich  closes  the 
orifices  in  the  pelvic  floor. 

The  diaphragma  pelvis  rectale,  or  proprium,  shortly  referred  to  as  the  pelvic

floor  or  diaphragm,  is  made  up  of  the  levator  ani  and  the  coccygeus,  together  with 
the  pelvic  fascia  above  and  below.  Anteriorly,  the  muscle  is  attached  to  the  back 
of  the  rami  of  the  pubis,  leaving  an  incomplete  space,  21^2  cm.  wide,  behind  the 
symphysis.  It  extends  on  either  side  across  the  opening  of  the  obturator  foramen, 
being  attached  to  the  fascia  covering  the  obturator  internus  muscle  by  the  "white 
line,"  or  arcus  tendineus  musculi  levatoris  ani.  On  vaginal  examination  this  arcus 
tendineus,  or  junction  of  the  fascia  obturatoria,  with  the  fascia  diaphragma  pelvis 
superiora,  can  often  be  felt  by  the  finger.  The  insertion  of  the  muscle  extends  to 
the  spines  of  the  ischia.  From  this  extensive  area  of  insertion  the  muscle-fibers  pass 
downward  and  inward  toward  the  median  line.  Posteriorly,  they  come  together 
on  the  lower  end  of  the  sacrum  and  the  coccyx;  anterior  to  this  they  interlace  in  the 
mecUan  line  behind  the  anus;   next  they  fuse  into  a  sling-like  hammock  under  the

perineal  curve  of  the  rectum;  finally  a  very  few  fibers  meet  between  the  anus  and 
vagina  in  the  perineal  body  (Luschka's  fibers).  Holl  gave  different  portions  of  the 
broad  muscle  special  names.  That  portion  going  from  the  spine  of  the  ischium  to 
the  coccyx  he  called  the  ischiococcj'geus;  that  from  the  arcus  tendineus  to  the 
raplie,  the  iliococcygeus;  that  from  the  posterior  surface  of  the  pubis,  passing  along- 
side the  urethra,  vagina,  and  rectum,  to  meet  its  fellow  in  a  tendinous  raphe  ex- 
tending from  the  tip  of  the  coccyx  toward  the  rectum,  the  pubococcygeus;  and, 
fourth,  a  strong  band  running  from  the  pubis  around  the  lower  part  of  the  rectum, 
sling-like,  the  puborectalis.  A  very  few  of  these  fibers  pass  in  front  of  the  rectum 
into  the  perineal  body;  a  few  attach  to  the  rectum  and  skin  (Fig.  181).  The 
diaphragm  thus  resembles  a  concave  broad  horseshoe,  incomplete  in  front,  leaving 
an  elliptic  opening.  Through  this  elliptic  space  pass  the  urethra,  vagina,  and  rec- 
tum. The  sides  of  the  muscle  slope  together  in  the  middle,  forming  a  V-shaped 
gutter,  leading  down  under  the  arch  of  the  pubis.  Fig.  182  shows  the  distribution 
and  action  of  the  various  portions  of  the  levator  ani  and  the  opposing  action  of  the

sphincter  ani.  When  the  levator  contracts  it  pulls  the  rectum  and  vagina  up  against 
the  pubis;  when  the  sphincter  contracts  it  draws  the  anus  and  the  lowest  portion 
of  the  rectum  backward,  the  result  of  the  two  forces  being  to  bend  the  rectum, 
closing  it  most  effectually'.  On  vaginal  examination  the  pul)ococcygeal  portions 
of  the  levator  can  easily  be  felt  as  two  roundish  i)illars  at  the  sides  of  the  vagina 
and  when  they  contract  the  finger  is  raised  up  to  the  pubis.  Beneath  the  pelvic 
diaphragm  lie  the  ischiorectal  fossic,  the  perineal  body,  the  diaphragma  urogenitale, 
the  vulva,  and  its  glands.  Of  these  we  need  consider  only  the  diaj^hragma  urogeni- 
tale (Fig.  184-),  which  closes  the  hiatus  genitalis.  This  is  a  three-cornered,  musculo- 
fibrous  septum,  fitted  into  the  pul)ic  arch  and  extending  backward  to  the  miterior 
wall  of  the  rectum.  It  is  made  up  of  the  deep  layer  of  the  perineal  fascia,  inclosing 
the  fibers  of  the  musculus  transversus  perinei  profundus  and  the  compressor 
urethrae.  A  few  of  these  fibers  reach  around  the  vagina  and  are  called  the  sphincter 
urogcnitalis  (Kalischer).  On  this  sejitum  lie  the  museuli  bulbocavernosi  (sphincter 
cunni),  the  ischiocavernosi,  and  the  transversi  perinei  superficiales.  These  nuiscles, 
mostly  rudimentary,  center  at  a  point  between  the  rectum  and  the  vagina  called 
11

by  Waldeyer  the  centrum  perineale,  or  centrum  tendineum  perinei  (Holl),  or  perineal 
body.  The  perineal  body  is  a  pyramidal  structure,  lying  between  the  rectum  and 
vagina,  wdth  its  apex  in  the  pelvic  diaphragm.  Its  base  is  the  skin  between  the  anus 
and  the  vulva.  Its  anterior  wall  is  the  vagina  and  fossa  navicularis,  the  posterior 
wall,  the  anus  and  rectum;  at  the  sides  it  broadens  out  into  the  ischiorectal  fossae. 
It  is  composed  of  fat,  fasciae,  the  rear  part  of  the  urogenital  septum,  the  fused  ends 
of  the  transverse  perineal  muscles,  the  bulbocavernosi,  the  anterior  fibers  of  the 
sphincter  ani,  and  the  skin.  It  has  great  obstetric  importance,  but  not  so  much  as 
that  of  the  pelvic  floor,  a  point  frequently  overlooked.     During  labor  the  perineal

body  is  flattened  out,  its  apex  is  pressed  down  and  back,  so  that  its  structures  come 
to  lie  on  the  distended  pelvic  diaphragm. 

The  sphincter  ani  externus  lies  between  the  skin  and  the  pelvic  diaphragm, 
surrounding  the  lower  end  of  the  rectum.  It  is  attached  posteriorly  to  the  coccjtc 
by  the  ligament um  anococcygeus,  and  anteriorly  to  the  centrum  tendineum.  Some 
of  its  fibers  go  circularly  around  the  anus,  some  continue  into  the  bulbocavernosus, 
some  circle  in  the  skin  near  the  anal  margin.  The  sphincter  ani  varies  much  in  size 
in  different  women :  it  may  be  as  thick  as  the  little  finger  and  as  broad  as  the  thumb- 
nail, or  only  half  the  size.     This  is  true  of  all  the  perineal  muscles.

THE  FORMATION  OF  THE  PARTURIENT  CANAL 

Before  it  can  reach  the  external  world,  the  child  has  to  pass  through  three 
rings  the  cervix,  the  opening  in  the  levator  ani  and  the  hiatus  genitalis,  the  %'ulva 
and  perineum.  It  is  forced  like  a  wedge  against  the  resistances  offered  by  these 
structures,  and  the  overcoming  of  these  structures  is  the  main  function  of  the  powers 
of  labor.  Normally,  the  head  is  forced  through  the  cervix  before  it  comes  down 
onto  the  pelvic  floor.  The  dilatation  of  the  diaphragma  urogenitale  occurs  together 
with  the  diaphragma  proprium,  and  together  they  are  made  to  form  a  fibromuscular 
canal  attached  to  the  bony  pelvic  outlet.  How  the  cervix  is  dilated  until  it  is  flush 
with  the  vagina  has  been  described  on  p.  121.  Fig.  185  shows  the  condition  of  the 
parturient  canal  at  the  time  when,  dilatation  being  complete,  the  fetal  head  has 
passed  through  the  cervix  and  come  to  rest  on  the  pelvic  floor.  Now  the  levator 
ani  begins  to  stretch.  It  is  displaced  downward  and  backward  with  all  the  soft 
parts  of  the  pelvic  outlet;  thus  these  structures  suffer  a  displacement  in  an  axial 
direction,  in  addition  to  being  dilated  radially.  This  lengthening  of  the  soft  parts 
is  greater  on  the  posterior  wall  than  on  the  anterior,  being  only  2  or  3  cm.  here, 
while  the  posterior  wall  is  stretched  10  cm.  The  bundles  of  the  levator  ani  are 
separated  and  long  drawn  out  (Figs.  186  and  187),  so  that  they  form,  with  the  pubic 
arch,  a  canal  whose  circumference  is  equal  to  the  head  of  the  child — 33  to  35  cm. 
The  urogenital  septum  lies  flat  on  the  outside  of  the  canal  and  dilates  with  it. 
Since  the  latter  septum  has  little  muscle,  and  connective  tissue  dilates  poorly,  it  is 
the  rule  for  tears  to  occur  in  this  structure  in  all  full-term  labors.  These  tears 
allow  a  sagging  of  the  anterior  vaginal  wall  and  urethra,  producing  the  so-called 


164 


PHYSIOLOGY    OF    LABOR 


"physiologic"  prolapse  of  these  structures.  The  sphincter  ani  is  stretched  from 
side  to  side  as  well  as  from  before  and  backward.  The  anus,  therefore,  gapes 
A\'idely  as  the  head  descends  low,  exposing  the  anterior  wall  of  the  rectum.  The 
rectum  is  flattened  out  against  the  sacrum  and  levator  ani.  Owing  to  the  attach- 
ment of  the  bladder  to  the  lower  part  of  the  uterus  it  is  drawn  up  into  the  abdominal 
cavity  together  with  this  portion  of  the  retracting  organ.  Indeed,  all  the  soft  parts 
behind  the  pubis,  the  ''pubic  segment"  (Barbour),  have  a  tendency  to  retract  up- 
ward, while  those  below,  in  front  of  the  sacrum,  the  "sacral  segment,"  are  pushed 
downward.  Hart  and  Barbour  have  likened  this  action  to  that  of  folding  doors, 
one  being  pulled,  the  other  being  pushed,  to  allow  an  object  to  pass  through  them. 
The  vagina  is  dilated  radially  and  axially,  to  form  a  lining  membrane  for  the  canal.

The  head  has  passed  through  the  cervix  and  come  to  rest  on  the  pelvic  floor. 


When  the  pelvic  floor  tears,  the  vagina  usually  does  also,  but  it  may  not.  These 
submucous  lacerations  of  the  levator  ani  are  difficult  to  recognize  and  hard  to  repair. 

We  may  show  the  shape  of  the  parturient  canal,  as  in  Fig.  188,  but  the  reader 
will  understand  that  it  exists  as  such,  in  its  entirety',  at  no  time  during  labor.  The 
advancing  head  produces  such  a  disposition  of  the  surrounding  structin-cs  only  at 
the  moment  it  is  passing  through  them.  For  the  purpose  of  instruction,  however, 
we  may  illustrate  the  completely  dilated  passages. 

Schroder  divided  the  canal  into  a  contractile  and  a  dilating  portion.  AH 
under  the  contraction  ring  or  internal  os  dilates;  the  uterine  muscle  above  it  con- 
tracts. Since  the  vagina  is  fastened  to  the  pelvic  floor,  contraction  of  the  uterus 
stretches  the  canal  from  this  point  upward,  and  the  advancing  head  pushes  the 
tissues  from  this  point  downward.     This  axial  stretching  of  the  canal,  if  carried

beyond  the  normal,  may  result  in  rupture  of  the  uterus  or  vagina,  and  experience 
shows  that  this  occurs  most  often  in  the  zone  extending  from  the  internal  os  to  the 
vagina.  The  radial  stretching  of  the  canal  is  greatest  when  the  largest  fetal  plane 
is  passing  a  given  point.  After  this  the  elasticity  of  the  walls  of  the  canal  adapts 
them  to  the  reduced  size  of  the  fetal  cylinder.

A  study  of  the  parturient  canal  will  show  that  it  runs  straight  down  until  it 
reaches  the  narrow  pelvic  plane  or  the  third  parallel  of  Hodge,  then  bends  forward  in 
a  sharp  curve  whose  center  is  the  symphysis  pubis.  If  the  passage  uses  the  space 
under  the  arch  of  the  pubis,  the  bend  in  it  is  quite  sharp.     If  the  arch  of  the  pubis  is

forcing  the  pelvic  floor  further  back  toward  the  sacrum,  making  a  more  obtuse  angle 
in  the  parturient  canal.  The  axis  of  the  parturient  canal  is,  therefore,  not  a  curve 
(the  curve  of  Carus),  but  a  straight  line  with  a  bend  at  the  pelvic  floor  and  a  curve 
(Fig.  189).

CHAPTER  XI 

THE  PASSENGERS 

For  the  study  of  the  mechanism  of  labor  a  coasideration  of  the  fetus 
as  a  mechanical  object  is  essential, — more  so  than  has  generally  been  allowed 
— and  we  must  consider  its  size,  shape,  compressibility,  and  pliability.  The  head 
is  larger  and  more  important,  but  the  trunk  takes  no  inconsiderable  part  in  the 
normal  mechanism  of  labor,  and,  when  pathologically  enlarged,  may  give  rise  to 
dystocia  and  even  cause  the  death  of  mother  or  child  or  both.  In  the  fetus  at  term 
the  face  is  small,  the  vault  of  the  cranium  forming  the  major  portion  of  the  head. 
Four  large  squamous  bones  make  up  the  cranial  vault — the  two  parietal,  the  frontal, 
and  the  occipital.  At  the  sides  the  temporal  bones  unite  with  the  parietals.  To 
provide  for  the  molding  necessary  in  the  child' s  passage  through  the  maternal  parts,

and  for  the  rapid  growth  of  the  brain  in  the  first  year  of  life,  these  bones  are  not 
united,  but  the  ossification  halts  at  the  lines  of  impingement,  which  later  become 
the  sutures  of  the  skull.  The  l^ones  are  held  together  by  the  membrane  in  which 
ossification  takes  place — the  chondrocranium.  The  lines  of  impingement  are 
called  sutures,  and  at  the  junctions  of  the  sutures,  owing  to  rounding  of  the  bony 
corners  of  the  separate  bones,  spaces  filled  by  membrane  are  left,  and  these  spaces 
are  termed  fontanels  (fonticuli).  Outside  of  the  configurability  conferred  on  the 
head  by  the  sutures  and  fontanels,  these  spaces  are  of  vital  imjiortance  to  the  jirac- 
tising  accoucheur,  for  by  means  of  them  he  determines  the  relation  of  the  head  to 
the  maternal  pelvis,  studies  the  mechanism  of  labor,  and  guides  his  application  of  the 
obstetric  forceps. 

Between  the  two  parietal  bones  lies  the  sagittal  suture  (Fig.  190) ;  between  the 
parietals  and  occipital,  the  bent  lambdoid  suture;  between  the  frontal  bone  and 
the  parietals,  the  coronary  suture,  while  between  the  two  plates  of  the  frontal  bone 

167 


168  PHYSIOLOGY   OF   LABOR 

lies  the  frontal  suture,  whose  length  varies.  At  the  sides,  where  the  parietal  bones 
touch  the  temporals,  lie  the  lateral  or  temporal  sutures,  of  little  obstetric  importance. 

At  the  junction  of  the  sagittal,  frontal,  and  coronal  sutures  lies  a  lozenge- 
shaped  space,  the  anterior  or  large  fontanel.  Its  size  depends  on  the  degree  of 
ossification  of  the  abutting  bones,  and  its  shape  also,  since  with  advanced  ossifica- 
tion it  becomes  more  square.  Four  sutures  run  into  the  large  fontanel,  which  fact 
distinguishes  it  from  the  others,  and,  of  its  angles,  three  are  obtuse  and  one  acute, 
which  points  enable  us  to  diagnose  the  position  of  the  fetal  head  in  the  pelvis.  The 
shortest,  obtuse  angle  (Fig.  191)  points  toward  the  occiput,  or  posterior  pole  of  the 
head,  the  long  acute  angle,  toward  the  face. 

Behind,  at  the  junction  of  the  sagittal  suture  with  the  lambdoid,  a  small  tri- 
angular space  exists,  called  the  posterior  or  small  fontanel.  It  is  best  to  use  the 
terms  small  and  large  fontanel  to  avoid  confusion  in  the  study  of  the  mechanism  of 
labor.     Three  sutures  enter  the  small  fontanel,  which  during  labor  is  obliterated  as 


Frontal  suture

a  space,  the  three  lines  coming  together  at  a  point  like  the  letter  Y.  The  stem  of 
the  Y  is  the  sagittal  suture  and  runs  toward  the  face. 

Where  the  lateral  sutures  meet  the  ends  of  the  coronary  and  lambdoid,  spaces 
exist  which  are  called  the  lateral  fontanels.  They  are  important  because  they  may 
impose  as  the  other  fontanels  and  lead  to  costly  diagnostic  errors.  The  ear  is  close 
to  the  posterior  lateral  fontanel,  the  bony  orbit  next  to  the  anterior,  and  hereby 
mistakes  are  readily  avoided.  Wormian  l^ones  are  accessory  centers  of  ossification 
which  sometimes  occupy  the  spaces  of  the  fontanels,  but  they  have  no  obstetric 
importance.  In  the  sagittal  suture  occasionally  a  quadrangular  space  is  found 
(Fig.  190),  which  is  most  easily  mistaken  for  the  large  fontanel,  and  may  cause  seri- 
ous errors  in  diagnosis.  It  is  a  false  fontanel.  Confusion  may  be  avoided  by  follow- 
ing the  sagittal  suture  to  its  terminal  fontanels. 

We  (hstinguish  the  regions  of  the  skull  by  particular  names.  The  occiput  is 
that  portion  (Fig.  193)  lying  l^ehind  the  small  fontanel;  the  sinciput  is  that  portion 
lying  anterior  to  the  large  fontanel;    the  bregma,  the  region  of  the  large  fontanel; 


THE   PASSENGERS  169 

the  vertex,  the  region  between  the  two  fontanels  and  extending  to  the  parietal  pro- 
tuberances. In  shape  the  fetal  head  is  irregularly  ovoid — narrow  in  front,  broad 
behind.  The  frontal  bono  is  quite  square,  the  result  of  the  angularity  of  the  frontal 
protuberances,  and  the  ])arietal  bones  have  on  each  sitle  a  ])romincncc  which  is 
more  or  less  sharp — the  parietal  bosses  (tubera  parietalia).  They  mark  the  points 
where  the  head  meets  the  greatest  resistance  in  passing  through  the  pelvis.  No 
inference  may  be  made  regarding  the  shape  of  the  child's  head  by  considering  those 
of  its  parents  because  it  may  resemble  cither  one;  usually,  however,  the  mother 
makes  the  greater  impress.  Certain  vagaries  have  been  noted  in  the  ossification  of 
the  sutures,  which  give  the  skull  peculiar  shapes.  If  the  sagittal  suture  unites  too 
early,  a  scaphocephalus  results:  the  head  is  boat-shaped,  being  as  broad  in  front  as 
behind.  If  the  frontal  suture  ossifies  early,  a  three-cornered  head  results — tri- 
gonocephalus.  In  similar  ways  brachycephalus — short  head — and  dolichocepha- 
lus — long  head — are  produced.  These  various  shai^es  modify  the  mechanism  of 
labor  and  may  ]^roduce  dystocia. 

The  fetal  head  diameters  vary  quite  a  little  within  normal  limits.     For  com-

parison  with  those  of  labor  they  should  be  taken  the  fourth  day  after  l)irth.     The 
measurements  here  given  are  the  averages  of  a  large  nunil)er  of  children  (Jaggard): 

Diameter  bii)arietalis — B.P.,  93-2  cm. 

Diameter  bitein])oralis — Bi.T.,  8  cm. 

Diameter  suboccipitobrefrmaticiis — S.O.B.,  932  C'"- 

Diameter  occipitofrontali.s — O.P".,  11  cm. 

Diameter  occipitomentalis — 0.^1.,  13  cm. 

There  are  many  other  diameters,  but  these  are  the  only  ones  ]:)ractically  neces- 
sary. Two  circumferences  of  the  head  should  be  taken,  the  large  and  the  small,  the 
first  taken  around  the  occipitofrontal  diameter,  the  other  around  the  suboccipito- 
bregmatic.     They  measure  34  and  31  cm.  respectively. 

The  trunk,  while  apparently  larger,  presents  smaller  diameters  to  the  birth- 
canal,  because  it  may  be  compressed  to  assume  cylindric  proportions.  In  some 
children  the  shoulders  are  very  broad,  in  others  relatively  much  smaller  than  the 
head.  Boys  usually  have  larger  heads  at  birth,  and  this  is  also  true  of  the  first 
child,  regardless  of  sex.  The  bisacromial  diameter  of  the  fetus  is  1 1  cm. ;  the  bisiliac, 
9  cm.     The  circumference  of  the  shoulders  is  34  cm. ;  of  the  chest,  32  cm. 

By  "attitude"  is  meant  the  relation  of  the  various  parts  of  the  fetal  body  to 
each  other.     The  normal  attitude  of  the  child,  when  there  is  no  scarcity  of  liquor

chest,  legs  on  the  thighs,  thighs  on  the  abdomen,  and  the  back  of  the  child  is  curved.

In  addition,  there  is  usually  some  lateral  flexure  of  the  head  on  one  shoulder.     (See

cient  space  to  stretch  out,  its  attitude  is  one  of  cramped  flexion.  The  extremities 
are  pressed  into  the  body,  crossing  each  other,  sometimes  even  with  bending  the 
long  bones,  and  shortening  of  the  muscles.  Occasionally  one  finds  decubitus  over 
the  bony  prominences.  Labor  in  such  cases  is  harder  and  is  often  attended  by 
irregular,  anomalous  uterine  action.     (See  Labor  in  Oligohydramnion.) 

Changes  in  the  Fetus  the  Result  of  Labor. — Sellheim's  x-ray  plates  and  Bar- 
bour's frozen  section,  together  with  clinical  studies,  give  us  a  clear  idea  of  the  mold- 
ing of  the  child  during  labor.  The  child  as  a  mechanical  object  for  labor  presents 
two  ovoids  joined  by  a  flexible  shaft,  the  neck.  The  trunk  is  flexible  to  a  certain 
degree,  and  more  flexible  in  certain  directions  than  in  others.  Since  this  jointed 
object  has  to  pass  through  a  bent  canal,  one  can  readily  perceive  that  this  adapta- 
bility will  come  into  play.  The  neck  is  most  readily  extended,  and  extension  is  its 
greatest  movement,  because  the  strong  posterior  neck  muscles  prevent  anj-  great

degree  of  flexion  of  the  chin  onto  the  sternum.  The  child  can  bend  its  dorsal  spine 
best  in  a  lateral  direction,  because  the  arms  and  thighs,  by  pressure  against  the 
trunk  from  the  front,  act  like  splints. 

When  labor  is  well  under  way,  the  frankh'  ovoid  shape  of  the  fetus  is  changed 
into  a  long  cylinder  or  ellipsoid.  The  uterus,  by  its  contractions,  forces  open  the 
lower  uterine  segment  and  cervix.  Its  cavity,  therefore,  lengthens,  its  walls  apply 
themselves  closer  on  the  fetus,  the  extremities  of  the  latter  are  pressed  against  the 
trunk,  the  latter  is  straightened  out,  the  fetus  is  lengthened.  This  lengthening  of 
the  child  is  easily  determined  during  every  normal  labor — one  finds  the  fundus  uteri 
rising  higher  toward  the  ensiform,  while  the  head  advances  through  the  birth-canal. 

Bj'  the  same  forces  the  head  is  flexed  on  the  sternum,  the  shoulders  thrown  up 
under  the  ears,  the  clavicles  standing  almost  vertically,  a  fact  easily  proved  by  ex- 
amination after  the  head  is  delivered.  This  action  fixes  the  head  on  the  trunk,  so 
that  there  is  onlv  one  direction  in  which  the  head  can  bend  readily,  and  that  is  ex-

tension.     The  effect  of  such  a  condition  on  the  mechanism  of  laljor  will  be  studied 
shortly. 

Fehling  proved  that  the  size  of  the  head  can  be  slightly  reduced  under  the 
pressure  of  labor  by  the  escape  of  cerebral  fluid  into  the  spinal  canal.  Perhai)s,  too, 
some  of  the  blood  in  the  brain  may  escape  into  the  cervical  veins.  It  is  questionable, 
however,  if  such  a  small  reduction  as  is  thus  possible  is  of  any  real  influence  in  the 
mechanism  of  labor.  The  configurability  of  the  skull,  on  the  other  hand,  is  of  ut- 
most importance.  Figs.  162,  163,  and  164  show  how  the  head  is  molded  in  the 
most  common  delivery.  When  the  child  comes  in  face  presentation,  other  cranial 
shapes  are  produced.  The  circular  pressure  of  the  uterus  forces  all  the  fetal  tissues 
into  conformation  with  the  cylindric  bore  of  the  birth-canal,  and  one  thus  finds  cross- 
sections  of  the  fetal  ellipsoid  to  show  almost  circular  outlines.  The  reduction  of  the 
bisacromial  diameter  may  be  as  much  as  2  cm.,  depending  on  the  hardness  of  the 
fetal  tissues.  If  the  child  is  overgrown,  it  is  poor  in  water,  and  the  flesh  is  tougher 
and  less  compressible.     Dystocia  is  common  in  these  cases.

PRESENTATIONS  AND  POSITIONS 

Authors  are  not  in  accord  in  classifying  the  various  ways  in  which  the  fetus 
may  present  itself  for  delivery.  Baudelocque  (1775)  described  94  presentations. 
Almost  any  portion  of  the  child's  person  can  present  itself  first  for  delivery, 
and  since  the  attitude  and  position  of  the  child  change  during  labor,  the  difficulties  in 
the  way  of  a  universally  acceptable  classification  are  apparent.  That  accepted  at 
the  Ninth  International  Medical  Congress  at  Washington,  1887,  is  generally  recog- 


FiG.   196. — The  Four  Quadrants  of  the  Pelvis. 

nized  as  the  best,  but  it  is  not  complete  enough.  In  the  terminology,  that  adopted 
by  the  Basle  Congress  has  been  employed. 

Definitions. — By  ^^'presentation"  is  meant  that  portion  of  the  fetus  which  is 
touched  by  the  examining  finger  through  the  cervix,  or,  during  labor,  is  bounded 
by  the  girdle  of  resistance.  According  to  Hodge,  it  is  that  part  felt  by  the  examin- 
ing finger  "toward  the  center  of  the  pelvis."  Much  confusion  will  be  avoided  if 
the  word  presentation  is  adopted  as  here  defined,  and  made  synonymous  Avith  the 
much-used  expression  "presenting  part." 

^^ Position"  is  the  situation  of  the  child  in  the  pelvis,  and  is  determined  by  the 
relation  of  a  given,  arbitrary  point  in  the  presenting  part  to  the  periphery  of  the 
pelvic  planes. 

"  The  point  of  direction"  is  this  arbitrary  point  in  the  presenting  part,  by  which 
we  determine  the  topographic  relation  of  the  presenting  part  to  the  periphery  of 
the  pelvic  planes.     In  occipital  presentation  the  occiput  is  the  point  of  direction; 


THE    PASSENGERS

in  breech  presentation,  tiie  sacrum;   in  shoulder  presentation,  the  scapula;   in  face, 
the  chin,  etc.     The  Germans  use  the  back  as  the  point  of  direction. 

"Attitude"  is  the  relation  of  the  fetal  members  to  each  other;  it  is  habitus  or 
posture.  The  attitude  of  the  fetus  has  much  to  do  wdth  its  presentation,  but  they 
are  not  identical.     Attitude  may  be  disturbed  by  the  arms  leaving  the  chest,  the 


Fig.  197.— O.L.A. 


legs  leaving  the  abdomen  and  prolapsing,  or  the  cord  prolapsing,  the  chin  extending, 
making  the  various  deflexion  presentations,  etc. 

All  terms  as  to  direction  are  referred  to  the  mother  in  the  erect  position.  The 
term  upper  means  the  part  in  the  direction  of  the  fundus  uteri;  lower,  the  part 
nearer  the  vulva;    anterior,  means  the  direction  to  the  front  of  the  mother;    right, 


174 


PHYSIOLOGY   OF   LABOR 


the  right  side  of  the  mother,  etc.— these  terms  having  no  apphcation  to  the  child. 
By  keeping  this  rule  in  mind,  confusion  will  be  avoided. 

For  convenience  of  description  the  pelvis  is  divided  into  four  quadrants — 
an  anterior  left,  an  anterior  right,  a  posterior  right  and  left  (Fig,  196).  The  posi- 
tion of  the  presenting  part  is  defined  according  to  that  ciuadrant  in  which  the  point 
of  direction  lies.     Three  grand  divisions  of  the  presentation  are  recognized:

Cephalic  presentation  and  its  varieties — vertex,  bregmatic,  brow, 
and  face.  The  vertex  is  the  normal,  the  others  are  transitional,  or 
pathologic,  being  due  to  deflexion  of  the  head.  They  are  sometimes 
called  ''deflexion  attitudes." 

Pelvic  or  breech  presentation  and  its  varieties — complete  breech, 
footling,  double  footling,  knee,  double  knee,  and  single  breech. 

Transverse  presentation,  including  shoulder,  arm,  and  any  part  of 
the  trunk. 


THE    PASSENGERS 


175 


In  the  first  two  groups  the  axis  of  the  fetus  Ues  parallel  with  that  of  the  uterus: 
in  the  last  group  it  lies  obliquely,  more  or  less. 

Presentation  has  to  do  with  the  part  of  the  fetus  which  presents  itself  to  the 
parturient  passage  first  for  delivery.  It  is  determined  by  the  attitude  of  the  child 
and  the  relation  of  its  axis  to  that  of  the  birth-canal.  Position,  in  its  technical 
sense,  means  the  relation  of  the  presenting  part  to  the  plane  of  the  pelvis  in  which  it 
lies;    that  is,  to  the  four  quadrants  of  the  pelvis.     Each  presenting  part  may  so 


Fig.   199.— O.D.P. 


occupy  the  pelvis  that  its  point  of  direction  may  lie  in  any  pelvic  diameter;  for 
example,  the  occiput  may  be  to  the  right,  to  the  left,  behind,  in  front,  or  at  any 
intermediate  point,  when  labor  begins.  The  most  common  locations  are  used  for 
teaching.  The  Committee  at  Washington  adopted  four  main  positions.  Six  are 
here  given,  and  other  writers  (Williams,  Farabeuf  and  Varnier)  also  distinguish 
them.  The  Latin  terms  and  abbreviations  are  to  be  ]^referred.  In  the  following 
table  the  positions  are  named  about  in  the  order  of  frequency :

The  back,  side,  or  belly  may  present,  but  these  are  rare,  and  come  readily 
under  the  above  classification. 

One  important  dimension  is  lacking  in  this  presentment.  How  are  we  to  de- 
termine the  distance  the  fetus  has  advanced  down  the  birth-canal  toward  the  vulvar 
outlet?     How  shall  we  convey  the  idea  of  the  location  or  degree  of  advancement  of 


THE    PASSENGERS

the  presenting  part  in  the  birth-canal?  ^Mullor  suggested  the  word  "station"  or 
" static,"  and  used  it  thus,  for  example,  "static  in  aditu,"  presenting  part  in  the  in- 
let, "static  in  exitu,"  at  the  outlet.  Bacon  is  the  only  American  teacher  who  has 
adopted  this  form.  Location  would  be  a  better  word.  The  term  "degree  of  en- 
gagement" was  used  by  Jaggard  and  is  often  employed,  and  the  entry  of  the  head 
into  the  pelvis  he  called  engagement. 

A  head  is  "not  engaged"  when  its  greatest  diameter  is  still  above  the  plane  of

the  inlet.  If  freely  mova])le,  we  call  it  "floating,"  or  "caput  ballitaljile."  A  head  is 
fixed  on  the  inlet  or  "engaging"  when  the  largest  diameter  is  just  al)out  to  pass  the 
inlet—"  caput  mobile."  A  head  is  "engaged "  when  the  largest  diameter  has  passed 
the  plane  of  the  inlet— "caput  ponderosum."  A  head  is  " deeply  engaged "  when 
the  largest  diameter  lies  in  the  narrow  pelvic  plane.  A  head  is  "at  the  outlet" 
when  the  largest  diameter  is  passing  the  bony  outlet.  The  perineum  is  beginning 
to  bulge  at  this  time.  A  head  is  " on  the  perineum "  when  the  largest  diameter  has 
passed  the  bony  outlet  and  the  head  Ijegins  to  show  in  the  vulva.  This  might  be 
called  the  period  of  disengagement.

178  PHYSIOLOGY    OF    LABOR 

A  diagnosis  of  the  mechanical  conditions  of  a  given  labor,  therefore,  requires  a 
statement  of  the  presentation,  the  position  of  the  presentation,  and  the  location  or 
degree  of  engagement  of  the  presenting  part.  The  last  is  of  great  importance,  but 
much  neglected,  and  often  with  fatal  results  to  mother  and  child.

FREQUENCY  OF  THE  PRESENTATIONS  AND  POSITIONS 

Karl  Braun,  in  48,449  cases,  found  vertex  presentations  in  95.9  per  cent.; 
pelvic  presentations,  2.7  per  cent. ;  face,  0.6  per  cent. ;  transverse,  0.7  per  cent.  Of  the 
vertex  presentations,  70  per  cent,  were  O.L.A.,  29  per  cent.  O.D.P.,  and  1  per  cent. 
the  other  two  positions.  Schroder,  from  a  clinical  study  of  over  250,000  cases, 
finds  the  vertex  in  95  per  cent.;  breech  in  3.11  per  cent.;  the  face,  0.6  percent.; 
and  transverse  presentations  in  0.56  per  cent.  Much  labor  has  been  spent  in  com- 
piling these  statistics,  but  their  value  is  not  great,  because  everything  depends  on 
the  time  when  the  diagnosis  is  made.  During  the  last  few  weeks  of  pregnancy  both 
the  presentation  and  the  position  of  the  fetus  maj^  change,  Schroder  claiming  this 
to  occur  in  32  per  cent,  of  the  cases.  The  most  frequent  changes  are  l^reech  and 
shoulder,  to  head.  Ordinarily  the  presentation  is  permanent  after  the  presenting 
part  has  engaged  in  the  pelvis,  but  this  is  not  invariable.  The  author  has  observed 
a  head  which  had  sunk  deep  into  the  excavation  rise  up  into  the  abdomen  again 
before  labor  set  in.  Hippocrates  believed  that  at  the  seventh  month  the  child, 
which  up  to  then  presented  by  the  breech,  turned  a  somersault  (variously  named, 
Culbute,  Inversio  Fetus — Peristrophe)  and  the  head  came  over  the  inlet. 

While  changes  of  the  long  axis  of  the  child  are  not  infrequent,  changes  in  posi- 
tion are  of  almost  daily  occurrence.  Examination  of  the  woman  on  successive  days, 
in  the  morning  and  evening,  will  show  the  back  now  on  one  side,  now  on  the  other. 
Multiparse,  because  of  the  lax  uterine  and  abdominal  walls,  show  the  most  marked 
mobility  of  the  fetus.  During  labor  the  fetus  may  also  alter  its  presentation  and 
position,  particularly  the  latter.  If  the  observer  happens  to  examine  the  patient 
early  in  labor,  he  may  find  an  O.L.P. ;  if  a  few  hours  later,  an  O.L.T.,  and  again  later 
an  O.L.A.,  or  even  an  O.D.A.  Hospital  statistics  differ  from  those  in  private 
practice  because  pathologic  labors  are  sent  to  hospitals.  Figures  from  the  one 
source  show  a  large  percentage  of  abnormal  presentations;  from  the  other,  a  neces- 
sarily smaller  percentage.  The  effect  of  all  these  factors  on  the  value  of  our  statistical 
information  is  evident. 

During  pregnancy  the  child  is  more  movable  and  accommodates  itself  to  the 
varying  position  of  the  mother.  When  she  is  erect,  its  back  falls  forward;  when  on 
the  side,  it  drops  to  the  side  on  which  she  lies.  This  explains  the  frequency  of  O.L.T., 
O.D.T.,  O.D.P.,  and  O.L.P.  in  our  routine  pregnancy  examinations.  One  examiner 
may  diagnose  O.D.A. ,  and  his  follower  O.D.P.,  the  change  having  resulted  from  the 
prolonged  dorsal  position  of  the  mother  and  displacement  l:)y  the  palpating  hand. 

Causes  of  the  Frequency  of  the  Cephalic  Presentations. — Hippocrates  believed 
gravitation  explained  the  predominance  of  head  presentation.  The  heavier  head 
sinks  to  the  lowest  part  of  the  uterus.  This  idea  was  held  until  very  recently,  when 
it  was  shown  that  the  head  is  very  little,  if  any,  heavier  than  the  breech,  and  that 
the  conditions  of  the  uterine  cavity  are  such  that  any  movement,  the  result  of  dif- 
ference in  weight,  would  be  more  than  nullified  by  the  friction  of  the  fetus  on  the 
uterine  wall.  Dubois  believed  the  fetus  instinctively  sought  that  position  which 
was  most  comfortable;  Simpson  referred  the  head  presentation  to  the  reflex  move- 
ments of  the  child  w^hen  it  was  forced  out  of  the  position  in  which  it  could  be  most 
easily  accommodated.     Cohnstein  gives  the  older  theories  in  full. 

The  law  of  accommodation  of  Pajot  explains  it  best.  Where  an  ovoid  l:»ody 
lies  free  in  an  ovoid  container,  the  two  long  axes  tend  to  become  parallel,  which  is 


THE    PASSENGERS 


179 


especially  true  if  the  container  has  contractile  power,  as  has  the  uterus.  The  child, 
as  it  lies  folded  together,  is  ovoid;  the  uterus,  at  the  end  of  pregnancy,  likewise. 
The  uterus  is  not  a  flaccid  sac,  but  has  some  tonus  and  keeps  its  form,  and  further 
it  contracts  frequently  (the  contractions  of  pregnancy).  During  these  contractions 
it  assumes  an  exquisitely  oval  shape,  and  one  can  readily  perceive  how  it  would 
gradually  force  the  contained  fetal  ovoid  to  conform  to  the  shape  of  its  cavity  (Figs. 
201,  202,  and  208).  Even  in  (!arly  pregnancy  the  head  lies  in  the  lower  segment  of 
the  uterus,  and  this  tendency  is  enhanced  by  the  shape  of  the  uterus  growing  more 
ovoid  all  the  time.  After  the  head  is  once  in  the  smaller  end  of  the  ovoid  it  is,  to 
an  extent,  anchored.  The  explanation  of  the  occurrence  of  the  various  positions  of 
the  child  is  easy.  With  the  woman  in  the  erect  posture  the  back  of  the  child 
will  naturally  occupy  the  roomy  anterior  half  of  the  uterus.  Behind,  the  lumbar 
spine  projects  sharply  into  the  uterine  ovoid  (Fig.  204),  and,  when  the  woman  lies 
down,  the  round  heavy  fetal  back  falls  to  one  or  the  other  side  of  it  (Fig.  205). 
Since  the  uterus  has  some  dextrolateral  torsion,  and  since  the  sigmoid  and  rectum 
push  forward  the  left  side  of  the  uterus,  a  cross-section  of  its  cavity  will  appear 
elliptic.     A  glance  at  the  figures  will  show  why  the  back  is  more  likely  to  be  found

in  the  left  anterior  portion  of  th(^  uterus  or  in  the  right  posterior.  The  l)ack  com- 
municates its  forward  or  backward  tendency  to  the  head,  rotating  it  on  an  axial 
diameter  so  as  to  bring  the  occiput  to  the  front  or  rear.  The  left  occipito-anterior 
position  is  over  twice  as  frequent  as  the  right  posterior,  and  this  dispro]:)ortion  be- 
comes greater  until  the  end  of  pregnancy.  During  the  twenty-four  hours  a  wt)man 
remains  twice  as  long  in  the  erect  posture  as  lying  down,  and,  therefore,  the  back  is 
more  likely  to  fall  to  the  front.  This  accounts  for  the  predominance  of  O.L.A. 
We  use  this  knowledge  to  influence  the  mechanism  of  labor.  Other  reasons  for  the 
frequency  of  O.L.A.  have  been  advanced,  as  the  flattening  of  the  right  half  of 
the  pelvis  and  enlargement  of  the  left  half,  the  right  oblique  diameter  of  the  inlet 
being  greater  than  the  left;  the  inclination  of  the  pelvis  to  the  left  side;  the  pres- 
ence of  the  liver  on  the  right  side,  but  they  have  little  influence.  The  location  of  the 
placenta  affects  the  location  of  the  back,  the  latter  usually  lying  opposite  the  former 
(Figs.  204  and  205). 

Abnormal  and  unusual  presentations  are  caused  by  absence  or  inefficiency  of 
the  above-mentioned  factors.  If  the  uterus  is  overdistended,  as  by  polyhydranmion 
or  twins,  its  walls  cannot  grasp  the  fetal  ovoid,  which,  therefore,  is  often  found  pre- 
senting wrongly.  IMultipane  with  flaccid  uterus  and  lax  abdominal  walls  (jicndulous 
belly)  suffer  often  with  malpresentations. 

A  small  or  premature  fetus  is  more  likely  to  present  by  the  l^reech  than  an  over-

growTi  child.  Hydrocephalic  children  and  anencephali  predispose  to  breech  pres- 
entation. Accident  is  a  factor,  as  when  labor  begins  suddenly  or  the  bag  of  waters

CHAPTER  XII 

THE  MECHANISM  OF  LABOR  IN  OCCIPITAL  PRESENTATION 

Although  the  movements  imparted  to  the  child  by  the  powers  of  labor  were 
knowTi  to  the  older  writers,  Baudelocque,  Smellie,  and  others,  and  Xaegele,  in  1819, 
described  them  minutely,  opinion  is  still  divided  as  to  their  causes.  If  the  student 
wishes  to  study  these  movements,  a  multipara  will  offer  better  advantages  than  a 
primipara,  ])ecause,  in  the  latter,  the  head  is  already  engaged  when  labor  Ix'gins. 
The  demands  of  asepsis  restrict  the  frequent  examination  of  the  parturient  which  is 
necessary  for  a  minute  study  of  the  mechanism.     The  use  of  sterile  rubber  gloves

and  extreme  antiseptic  precautions  will  reduce  the  danger  of  infection,  and  a  few 
thorough  examinations  will  give  the  student  a  great  deal  of  information. 

Broadly,  the  mechanism  of  delivery  is  as  follows:  An  object  consisting  of  two 
ovoids  united  by  a  hinge  (i.  e.,  the  head  and  trunk  united  l)y  the  neck)  is  to  be 
forced  through  a  passage,  straight  at  the  beginning  and  sharply  curved  at  its  lower 
end.  We  must  consider  the  manner  of  passage  of  the  head  and  of  the  trunk. 
Each  makes  three  movements — engagement,  or  entry  into  the  pelvis;  rotation,  or 
adaptation  to  the  shape  of  the  pelvis,  and  disengagement,  or  exit  from  the  pelvis. 

Engagement  of  the  Head.— Multipara,  O.L.A.— At  the  beginning  of  labor 
the  head  lies  over  the  inlet,  inclined  but  Uttle  on  either  shoulder.     The  sagittal 

181 


182 


PHYSIOLOGY    OF   LABOR 


suture  lies  about  midway  between  the  promontory  and  the  pubis — perhaps  a  Uttle 
nearer  the  pubis  if  the  promontory  juts  sharply  forward.  The  head  is  then  said  to 
be  synclitic  or  in  synclitism  (Fig.  206).  The  occipitofrontal  plane  lies  parallel  to 
the  region  of  the  inlet.  If  the  woman  has  a  pendulous  belly,  being  a  multipara,  or 
if  the  pelvis  is  contracted,  preventing  a  normal  mechanism,  the  body  of  the  fetus 
falls  forward,  the  sagittal  suture  nears  the  promontory,  the  head  presents  its  an- 
terior parietal  bone  to  the  parturient  canal,  the  parallelism  between  the  occipito- 
frontal plane  of  the  head  and  the  plane  of  the  inlet  is  destroyed,  the  head  is  asyn- 
clitic — it  is  in  anterior  asynclitism.  This  is  often  called  Naegele's  obliquity  (Fig. 
207).  If  the  woman  is  a  primipara,  the  abdominal  walls  holding  the  child  firmly 
against  the  spine,  the  head  may  be  inclined  on  the  inlet  with  the  posterior  parietal 
bone  more  to  the  front,  again  disturl^ing  the  parallelism.     This  is  posterior  asyn-

elitism  (Fig.  208).  Naegele  believed  the  head  usually  entered  the  pelvis  in  anterior 
asynclitism,  but  extended  investigation  has  disproved  this  view.  The  author  has 
usuallj'  found  the  sagittal  suture  about  midway  between  the  promontory'  and  the 
pubis.  Marked  asynclitism  is  pathologic.  (See  p.  696.)  The  sagittal  suture  also 
usually  runs  transversely  across  the  pelvis,  and,  in  a  multipara,  one  finds  the  small 
and  the  large  fontanels  in  the  same  plane  of  the  pelvis.  The  head,  therefore,  usually 
enters  the  inlet  with  its  long  diameter  in  the  transverse  of  the  pelvis;  and  since  the 
two  fontanels  are  about  as  easily  reached  by  the  examining  finger,  we  conclude  that 
the  head  is  not  strongly  flexed  on  the  chest.  Many  authors  dispute  the  former  of 
these  statements,  claiming  that  the  head  enters  the  pelvis  in  one  of  its  oblique  di- 
ameters, especially  th(^  right,  Ijut  the  author,  after  careful  study  of  hundreds  of 
labors,  believes  the  head  enters  transverseh^  in  the  majority  of  cases.  Naegele 
showed  it  entered  either  in  the  oblique  or  in  the  transverse.     Sir  Fielding  Ould,  of 


THE    MECHANISM    OF    LABOR    I\    OCCIPITAL    PRESENTATION 


183 


Dublin,  corrected  the  ancient  notion  that  the  head  entered  the  inlet  with  the 
occiput  to  the  pubis.     Pathologically  it  may  do  so. 

De.'icent. — As  soon  as  the  uterine  contractions  begin,  general  intra-uterine  pres- 
sure tends  to  force  the  fetus  downward,  and  when  the  os  is  completely  dilated,  rapid 
descent  begins.  Descent  of  the  head  is  also  favored  l)y  the  extension  of  the  fetal 
body.     (See  p.  171.) 

One  result  of  descent  is  an  increase  of  the  flexion  of  the  head.  Mechanically 
the  head  acts  like  a  two-armed  lever,  with  the  fulcrum  at  the  junction  of  the  spine 
with  the  occi])ital  condyles.  The  sinciput  and  occiput  meet  equal  resistances  in 
the  birth-canal,  but  the  sincipital  end  of  the  head  lever  is  longer  than  the  occipital 
end,  wherefore  the  sinciput  is  held  back  and  the  occiput  descends.  Any  ellipscjid 
body  passing  through  a  canal,  in  order  to  cause  the  least  resistance,  will  adapt  its 
long  axis  to  the  long  axis  of  the  canal.     The  mechanical  gain  in  flexion  is  that  in-

stead  of  an  occipitofrontal  diameter  of  12  cm.  and  a  circumference  of  35  cm.,  there 
is  presented  to  the  birth-canal  the  suboccipitobregmatic  plane  with  a  diameter  of 
9  cm.  and  a  circumference  of  31  cm.  P'lexion  may  be  marked,  as  occurs  in  generally 
contracted  pelves.  It  may  not  occur  until  the  head  is  well  do\\ni  on  the  pelvic  floor, 
and  thus  labor  may  be  delayed.  Another  result  of  descent  and  flexion  is  the  dis- 
appearance of  asynclitism,  that  is,  the  parallelism  is  restore<l,  ''leveling''  occurs, 
the  sagittal  suture  approaches  the  middle  of  the  pelvis  (Fig.  209) . 

In  pathologic  cases  the  asynclitism  persists  after  engagement  and  may  interfere 
with  the  next  movement,  rotation.  Descent  of  the  head  into  the  pelvis,  or  engage- 
ment, is  one  of  the  most  important  j^henomena  of  labor  presented  to  the  accoucheur 
for  study,  and  clinically  its  importance  is  vital.  A  head  is  engaged  in  the  pelvis 
when  the  biparietal  diameter  has  passed  the  region  of  the  inlet. 

Internal  Rotation. — The  lowest  part  of  the  head  now  nears  the  pelvic  floor  and 


184 


PHYSIOLOGY   OF   LABOR 


a  neAv  movement  is  imparted  to  it.  The  occiput  rotates  from  the  transverse  diam- 
eter into  the  obhque,  and,  finally,  anteroposteriorly.  This  movement  is  called 
internal  anterior  rotation,  and  many  theories  are  advanced  to  explain  it.  One  of 
the  oldest  notions  was  that  the  pelvis  presented  a  long  transverse  diameter  in  the 
inlet  and  a  long  sagittal  diameter  at  the  outlet,  and  that  the  head  had  to  seek  these 
diameters  in  its  passage.  This  is  only  partly  true.  If  one  looks  into  a  pelvis  from 
above,  one  will  see  the  spines  of  the  ischia  projecting  sharply  into  its  lumen.  The 
sides  of  the  pelvis  anterior  to  the  spines  curve  gracefully  dowmward,  forward, 
and  inward.  A  finger  following  the  curve  glides  gently  forward  under  the  pubis. 
Without  doubt  this  portion  of  the  bone  forming  a  part  of  the  lateral  inclined  planes, 
so  important  to  Hodge,  has  some  slight  function  in  anterior  rotation.     Its  action

may  be  likened  to  the  ways  of  a  ferry-boat.  The  levator  ani  hangs  like  a  sling,  or 
trough  or  gutter,  from  the  sides  of  the  pubis,  with  the  direction  of  its  canal  from 
behind  forward.  The  occiput,  sliding  down  the  side  of  the  pelvis,  is  directed  under 
the  pubis,  the  long  diameter  of  the  head  accommodating  itself  to  the  length  of  the 
trough,  according  to  the  law  of  inclined  planes.  Since  the  occiput  is  almost  alwaj'S 
lower  than  the  sinciput,  it  strikes  the  pelvic  floor  first,  and,  therefore,  has  the  greater 
tendency  to  rotate  anteriorly  under  the  pubis  (Fig.  210).  Examination  at  this 
period  of  labor  will  demonstrate  the  action  of  the  pelvic  floor  in  rotating  the  head 
forward.  Experiment — forcing  the  head  through  the  pelvis  of  a  female  cadaver — 
shows  that,  as  long  as  the  integrity  of  the  pelvic  floor  is  m-eserved,  its  action  is  to 
force  the  occiput  forward  (Fig.  211).  In  women  with  olq  lacerations  of  the  pelvic 
floor  anterior  rotation  is  often  delayed  or  absent. 


THE    MECHANISM    OF   LABOR   IN    OCCIPITAL   PRESENTATION

Schroder  and  Olshausen  believe  that  the  rotation  of  the  Imck  is  communicated 
to  the  head.  When  the  uterus  contracts  in  the  second  stage  it  flattens  from  side 
to  side,  and  the  trunk  of  the  chikl  finds  better  lodgment  in  the  anterior  bellying

of  the  uterus.  That  the  back  rotates  to  the  front  is  easilj^  demonstrable  in  most 
labors.  The  flexion  of  the  chin  on  the  sternum  and  the  raising  of  the  shoulders 
against  the  head  tend  to  fix  the  head  and  trunk  so  that  when  the  back  turns,  the 
head  goes  with  it.  One  may  easily  convince  himself  of  this  by  making  the  move- 
ment ^^^th  a  new-born  infant.  After  the  head  has  rotated  and  is  deep  in  the  pelvis, 
the  back  does  not  follow  it  fullj^,  remaining  behind  about  30  degrees  (Schatz). 
In  cases  where  the  back  remains  persistently  behind,  anterior  rotation  does  not 
occur,  and  such  concUtions  are  pathologic.  In  manual  correction  of  occipitopos- 
terior  positions  the  operator  knows  that  unless  he  can  get  the  back  to  the  front, 
rotation  of  the  head  is  incomplete  or  impossible  or  unstable. 

Sellheim,  in  most  elaborate  fashion,  proves  that  the  bod}^  of  the  child  possesses 
qualities  which  determine  its  movements  in  the  birth-canal.  As  was  described 
before,  the  child  during  labor,  in  order  to  present  the  least  resistance  to  the  birth- 
canal,  is  compressed  into  the  shape  of  a  cylinder.  This  fetal  cj'linder  bends  with 
facility  only  in  certain  directions.     The  head  bends  backward,  i.  e.,  deflexes  easily, 


Fig.  212. — Action  of  an  Evenly  Flexible  Cylinder  when  FoRrED  through  a  Curved  Passage. 
The  cylinder  A,  uniformlv  flexible,  in  going  through  the  canal  C,  will  simplv  bend,  the  line  x-y  not  changing  its  relation 

to  C. 


and  this  deflexion  is  aided  b}-  tlie  natural  movements  of  the  child.  The  head 
cannot  be  bent  much  onto  the  chest.  Owing  to  the  pressure  of  the  arms  and  legs 
onto  the  body  and  the  construction  of  the  spinal  column,  the  trunk  cannot  l;)end 
sagittally,  but  may  bend  easily  toward  one  or  the  other  side. 

One  may  readily  see  that  the  fetal  cylinder  will  be  bent  in  its  passage  through 
the  curved  birth-canal,  to  correspond  with  the  curve  of  the  canal.  If  the  child 
were  flexible  evenly  in  all  directions,  a  bending  of  the  cylinder  in  an  anteroposterior 
diameter  would  be  all  that  would  be  necessary.  But  the  bending  of  the  cylinder 
can  occur  only  in  certain  ways — at  the  neck  from  before  behind,  in  the  trunk  from 
one  side  to  the  other,  and  these  two  directions  cross  each  other  at  a  right  angle. 
Therefore,  in  order  for  the  fetal  cylinder  to  pass  through  the  curved  canal,  it  must 
rotate  on  its  long  axis  so  as  to  bring  the  plane  in  which  the  bending  can  most  easily 
occur  to  correspond  v^ith  the  axis  of  the  birth-canal  (Fig.  212).  In  other  words, 
the  child  is  forced  to  rotate  until  that  part  of  its  body  which  can  be  most  easily 
bent,  that  is,  the  nape  of  the  neck,  comes  to  be  adapted  to  the  knee  of  the  canal. 
The  movement  is  similar  to  that  of  pushing  the  foot  into  a  boot  when  the  action  is 


THE    MECHANISM    OF    LABOR    IX    OCCIPITAL    PRESENTATION

started  wrongly — as  the  foot  advances  it  rotates  until  the  eurve  at  the  ankle  corre- 
sponds to  the  curve  of  the  hoot  (Fiji.  21.'^). 

Anterior  rotation  of  the  child  from  all  positions  of  the  pelvis  may  be  explained 
by  this  law  of  the  acconunodation  of  elastic  resistance  to  the  shape  of  the  container 
(Sellheim). 

While  admitting  the  full  i)()wer  of  Sellheim's  arguments  and  proof,  and  agree- 
ing with  him  that  this  law  exj^lains  the  rotation  of  the  head  and  trunk,  the  other 
factors,  esj^ecially  the  construction  of  the  pelvic  gutter  and  the  action  of  the  trunk 
on  the  head,  must  be  also  adequately  evaluated.

The  cylinder  A  has  a  flat  steel  rod  at  X  Y.     This  rod  cannot  bend  on  the  edge,  only 
on  the  flat.     Therefore,  in  order  to  accommodato  itself  to  the  curve  of  C,  it  must  rotate 
the  cylinder  A.     Note  the  direction  of  the  arrows.

Disengagement. — Descent  continues  during  anterior  rotation,  as  also  tloes 
flexion  of  the  head.  Indeed,  flexion  is  exaggerated  by  the  resistance  of  the  peh'ic 
floor,  the  forehead  being  pressed  upward  by  the  resistant  sacrosciatic  ligaments, 
the  tip  of  the  coccyx,  and  the  levator  ani  (Fig.  214).  After  the  forehead  has  pa.^sed 
the  coccyx,  and  the  nape  of  the  neck  has  come  to  lie  under  the  arch  of  the  iiu])is, 
deflexion  of  the  head  Ix-gins.  The  chin  leaves  the  chest,  th(>  occijnit  rises  in  front 
of  the  pubis,  the  forehead  presses  out  the  soft  perineum,  and  the  head  is  delivered  in 
extension  (Fig.  215).  The  causes  of  extension  are  generally  agreed  upon.  The 
head  meets  an  inclined  plane — the  perineum.  The  fetal  axis  }iressure,  or  the  general 
intra-uterine  pressure,  forces  the  trunk  down  upon  the  heatl.  acting  only  on  the 
sincipital  arm  of  the  head  lever,  since  the  occipital  arm  is  untler  the  pubis.     The 


188 


PHYSIOLOGY   OF   LABOR 


parietal  bosses  strike  the  sides  of  the  levator  aiii  near  the  rami  pubis,  and  are  held 
firmly  while  the  forehead  is  driven  down  and  forward  (Fig.  216).  The  perineum  is 
thus  displaced  downward  as  well  as  backward,  a  point  of  importance  in  considering 
lacerations  of  the  pelvic  floor  and  their  repair. 

External  Restitution.— After  the  head  is  delivered  it  slowly  rotates  in  a  direction 
opposite  to  that  taken  in  internal  anterior  rotation;  that  is,  in  O.L.  positions  the 
occiput  turns  to  the  left,  in  O.D.  positions  it  turns  backward  toward  the  right, 
side  of  the  mother.  The  movement  is  called  "external  restitution,"  and  is  due  to 
the  untwisting  of  the  neck  and  to  the  impulse  imparted  to  the  head  by  the  internal 
rotation  of  the  shoulders.  External  restitution  or  rotation  does  not  invariably 
occur,  and  occasionally  the  occiput  turns  in  a  direction  opposite  to  that  which 
was  expected.     This  is  due  to  an  unusual  internal  rotation  of  the  shoulders. 

When  and  where  do  these  various  movements  take  place?     Descent  or  ad-

vancement,  or  translation  (Sellhcimj,  occurs  throughout  the  whole  process,  even 
when  the  head  is  rotating — a  point  to  bear  in  mind  when  imitating  nature's  method, 
as  in  a  forceps  delivery. 

Flexion  takes  place  at  the  inlet  of  the  pelvis,  but  may  not  until  the  head  has 
reached  the  pelvic  floor,  when  flexion  and  rotation  occur  almost  simultaneously. 
It  occurs  toward  the  end  of  the  first  stage  in  primiparse,  and  in  multiparae  in  the 
second  .stage.  The  flexion  is  exaggerated  when  the  head  is  ready  to  disengage  from 
the  bony  outlet  of  the  pelvis,  and  this  occurs  about  the  middle  of  the  second  stage. 

Internal  anterior  rotation  takes  place  in  the  excavation  of  the  pelvis,  just  as 
the  head  comes  to  rest  on  the  pelvic  floor,  and  is  completed  when  the  head  has 
escaped  the  bony  pelvis ;  though  often,  perfect  rotation,  bringing  the  small  fontanel 
absolutely  into  the  median  line,  may  not  occur  at  all,  the  head  being  delivered 
slightly  obliquely.  Absence  of  rotation  can  occur  only  when  the  child  is  small  and 
soft,  or  the  pelvis  very  large,  and  is  pathologic.     Internal  rotation  usually  begins- 


THE   MECHANISM    OF    LABOR   IX    OCCIPITAL    PRESENTATION 


189 


in  primiparae  when  the  first  stage  is  ended  and  is  completed  before  the  second  stage 
is  half  over.     In  multipariE  it  occurs  in  the  second  stage. 

Extension  occurs  after  the  forehead  has  passed  the  bony  outlet,  toward  the  end 
of  the  second  stage  of  both  priniipar«  and  multiparae. 

Mechanism  of  the  Shoulders. — When  the  head  becomes  visible  in  the  vulva, 
the  shoulders  engage  in  the  inlet,  the  bisacromial  diameter  usually  entering  in  the 
oblique  opposite  to  that  in  which  the  head  entered.  In  O.L.A.  one  finds  the  shoul- 
ders in  the  left  oblique;  in  O.L.P.  they  enter  in  the  right  oblique.  In  O.L.A.  the 
anterior  shoulder  rotates  under  the  pubis  from  the  right  side  of  the  pelvis,  its 
direction  of  progression  being  opposed  to  that  which  the  head  underwent ;  while  in 


Fig.  215. — Movement  of  Extension  and  Disengagement. 


O.L.P.  the  anterior  shoulder  follows  the  movement  of  the  head  from  the  left  behind 
to  the  pubis  in  front.  The  movements  imparted  to  the  shoulders  are  engagement, 
rotation,  and  disengagement.  CJeneral  intra-uterine  pressure  forces  the  child  down 
the  parturient  canal,  and  this  action  is  reinforced  b^'  the  direct  pressure  of  the 
uterus  on  the  fetal  body.  The  anterior  shoulder  slides  down  the  lateral  wall  of  the 
pelvis  until  it  reaches  the  pelvic  floor,  then  rotates  under  the  pubis.  Anterior  rota- 
tion of  the  shoulders  is  accomplished  by  the  same  factors  which  operate  on  the  head-— 
the  shape  of  the  pelvic  floor,  the  tlirection  of  the  opening  in  the  pelvis,  and  the  elastic 
resistances  of  the  fetal  ])ody.  Flexion  of  the  child's  trunk  is  necessary  to  accommo- 
date it  to  the  concavity  of  the  pelvic  canal.    The  child's  body  bends  best  laterally, 


190

and,  therefore,  according  to  Sellheim's  law,  the  trunk  will  rotate  until  it  corresponds 
to  the  direction  of  the  curve  of  the  canal  through  which  it  has  to  i)ass  (Fig.  217). 
In  rare  cases  no  rotation  of  the  back  occurs,  the  shoulders  appearing  transversely,

Parietal  bosses  meet  resistance  at  B  B.      There  is  a  tendency  for  A  to  come  down,  which  is  opposed  by  perineal  floor, 

giving  curve  A  A'.

and  sometimes  the  shoulders  rotate  to  the  opposite  obUque,  the  back  appearing  on 
the  other  side  to  that  in  which  it  was  expected,  l^ehvery  of  the  shoulders  is  quite 
typical.  The  anterior  shoulder  stems  behind  the  pubis,  the  posterior  rolls  up  over 
the  perineum,  after  which  the  anterior  shoulder  conies  from  behind  the  pubis. 
If  the  perineum  is  much  torn,  a  reverse  mechanism  occurs.  Often  nature  needs 
a  little  aid  at  this  stage,  and  the  accoucheur  must  imitate  the  natural  modus  of 
delivery.  Trouble  with  the  shoulders  is  rare  unless  they  are  large,  but  lacera- 
tion of  the  perineum  frequently  results  from  carelessness  in  their  delivery,  as 
also  may  fracture  of  the  child's  clavicle — even  Erb's  paralysis.  (See  p.  813.) 
After  the  chest  is  born,  the  rest  of  the  child  follows  without  any  particular  mechan- 
ism. 

Over-rotation. — One  is  occasionally  surprised  to  note  that  a  labor  starting  out 
O.L.A.  becomes,  in  its  course,  an  CD. A.,  and  external  rotation  follows  such  a 
mechanism.  In  these  cases  the  internal  rotation  was  excessive,  carrying  the  occiput 
beyond  the  middle  line  to  the  opposite  side,  or  the  internal  rotation  of  the  shoulders 
was  reversed  or  excessive.  The  explanation  of  the  phenomenon,  after  removing  the 
question  of  error,  is  to  be  found  in  the  laws  governing  the  mechanisms,  and  one

usually  finds  that  the  child  was  .small  or  the  parts  large  and  yielding,  the  factors  in 
the  jiroduction  of  a  ])erfect  mechanism  l)eing  weakened. 

What  One  Observes  of  the  Mechanism  of  Labor  in  O.L.A. — Careful  observa- 
tion of  the  course  of  labor  enables  us  to  closely  follow  the  mechanism,  to  determine, 
at  any  time,  its  rate  of  progress,  and  to  discover  any  \-ariation  from  the  normal. 
It  is  the  knowledge  of  the  mechanism  of  labor  and  the  aljility  to  recognize  and  correct 
abnormal  variations  that  mainly  distinguish  the  real  accoucheur  from  the  blind 
midwife,  male  or  female.  It  will  simplify  and  clarify  this  study  if  the  student 
will  follow  the  described  mechanisms  on  the  manikin  or  with  a  pelvis  and  fetal 
skull.  A])dominal  examination  furnish(>s  most  valual)le  information,  is  less  danger- 
ous to  the  patient,  less  ])ainful,  and  should  always  be  practised  first,  though  it  is 
often  necessary  to  supplement  it  by  internal  or  vaginal  exploration. 

At  the  beginning  of  uterine  contractions  the  uterus  is  more  globular  than  later, 
and  slightly  more  pendulous.  The  head  is  higher  up,  and  movable  al)ove  the  inlet, 
especially  in  multii)ara\  and  the  back  is  usually  far  to  the  side.  When  the  con- 
tractions attain  regularity  and  severity,  the  uterus  leng-thens.  the  head  becomes 
fixed  over  the  inlet,  and  the  back  shows  a  tendency  to  come  to  the  front,  or  go 


192  PHYSIOLOGY    OF   LABOR 

further  back  to  the  side,  the  latter  movement  depending  on  the  position — whether 
an  anterior  or  a  posterior  one.  Fig.  219  shows  the  hands  palpating  the  head  before 
it  engages  in  the  pelvis;  one  sees  how  the  fingers  can  move  the  head  from  side  to 
side  above  the  inlet.  Fig.  220  shows  the  hands  as  they  come  to  rest  on  the  head, 
after  it  has  engaged;  one  hand  feels  the  occiput  deep  in  the  pelvis,  to  the  left, 
behind  the  pubic  ramus;  the  other  hand  finds  the  sharp  forehead  on  the  right  and 
somewhat  behind  the  median  line.     When  flexion  is  marked,  as  in  generally  con-

tracted  pelves,  one  can  hardly  feel  the  occiput,  it  is  so  low  in  the  pelvis,  but  the  fore- 
head is  high  up  and  easily  palpated.  If  one  now  tries,  with  the  two  hands,  to  push 
the  head  from  side  to  side,  it  will  be  found  impossible:  the  head  is  fixed.  As  labor 
goes  on  and  internal  anterior  rotation  occurs,  the  occiput  sinks  behind  the  left  pubic 
ramus  out  of  reach  of  the  external  hand,  and  the  forehead  rises,  then  turns,  dis- 
appearing in  the  right  flank.  When  the  occiput  sinks  beyond  the  reach  of  the  fingers, 
the  head  is  engaged.

The  back  at  first  is  directed  to  the  left  side,  but  as  labor  advances  it  rotates 
to  the  front.  One  can  follow  the  anterior  shoulder  as  it  goes  from  the  left,  behind 
above,  to  the  middle  line  just  over  the  pubis.  The  movement  of  the  back  is  also 
depicted  by  the  course  of  the  fetal  heart-tones.  At  first  the  i)()int  of  their  greatest 
intensity  is  about  the  level  of  the  navel,  on  the  left;  this  point  descends  and  comes 
to  the  median  line  until,  when  the  head  is  on  the  i)erineum,  the  heart  is  best  heard 
just  above  the  pubic  hair  margin. 

On  vaginal  exploration,  early  in  labor,  one  finds  the  cervix  closed  or  admitting 
only  one  or  two  fingers,  which  renders  the   diagnosis   very  difl^cult.     In   primi-

parse  the  head  is  often  engaged;  in  multipara?  it  usually  lies  in  the  inlet,  l)ut  freely 
moval)le,  floating,  or  "caput  ballitabile. "  The  finger  in  the  cervix  comes  upon 
the  soft  bag  of  waters,  and  through  this  feels  the  head.  Lying  across  the  os  is  the 
sagittal  suture,  running  medially  (synclitism)  or  nearer  the  promontory,  or  j^ubis 
(asynclitism),  and  at  the  end  of  the  suture,  in  the  left  anterior  pelvic  quadrant,  the 
finger  finds  the  small  fontanel.  At  the  other  end,  in  the  right  posterior  quaih^ant, 
but  nearly  on  a  level  with  the  small,  lies  the  large  fontanel.  These  findings  indicate 
that  flexion  has  not  yet  occurred.  Flexion  having  taken  place,  one  finds  the  small 
fontanel  lower  in  the  pelvis  and  nearer  its  center,  the  large  fontanel  higher  and

harder  to  reach,  the  sagittal  suture  more  nearly  paralleling  the  axis  of  the  body,  and 
lying  almost  in  the  right  oblique.  That  fontanel  which  is  nearer  the  center  of  the 
pelvis  is  the  lower  one.    Internal  anterior  rotation  occurring,  the  small  fontanel  de-

scends  and  sweeps  around  the  left  anterior  quadrant  of  the  pelvis  until  it  lies  directly 
behind  the  pubis,  the  sagittal  suture  now  running  exactly  in  the  median  line  from 
before  backward  (Figs.  222,  223,  and  224).  Coincident  with  the.se  movements  the 
effacement  and  dilatation  of  the  cervix  have  been  taking  place,  and  usually,  by  the

PHYSIOLOGY   OF   LABOR 


time  the  head  comes  to  rest  in  the  perineal  gutter,  the  os  is  completely  dilated  and 
retracted  above  the  neck.  A  caput  succedaneum  begins  to  form,  and  in  long, 
tedious  labors  may  grow  so  large  that  it  makes  the  landmarks  on  the  skull  hard  to 
find.  Firm  pressure  or  massage  ^^^ll  obviate  the  difficulty.  Of  equal  importance 
to  the  determination  of  the  rotation  is  the  recognition  of  the  degree  of  engagement 
of  the  fetal  head — the  "  station  "  (Miiller) .  It  is  not  so  easy  to  determine  the  degrees 
of  advancement  of  the  head  along  the  birth-canal.  Older  writers  sought  to  decide 
this  point  by  pushing  the  head  up,  and  much  use  was  made  of  the  terms  "caput 


Fig.  227. — ConRSE  of  Fetal  Heart-tones  in  O.D.P. 


ballitabile,  mobile,  and  ponderosum. "  When  the  head  floated  above  the  inlet,  it 
was  called  "caput  ballitabile";  when  it  was  fixed  at  the  inlet,  "caput  mobile";  when 
deep  in  the  pelvis,  "caput  ponderosum."  A  head  that  is  even  visible  at  the  outlet 
may  be  pushed  up  out  of  the  pelvis,  and  a  head  that  is  not  engaged  may  be  fixed  so 
that  it  cannot  be  moved;  therefore,  one  may  not  be  guided  by  the  displaceability. 
The  head  is  engaged  when  its  largest  plane — that  is,  the  one  through  the  parietal 
bosses — has  passed  the  region  of  the  inlet.  How  may  we  determine  that  such  has 
occurred?  We  know  that  the  head  is  engaged  when,  first,  the  most  dependent 
portion  of  the  skull  (not  the  caput  succedaneum)  has  passed  a  line  drawn  between 
the  spines  of  the  ischia;  second,  when  two-thirds  of  the  sacrum  are  covered  by  the 
cranial  prominence,  that  is,  the  sacral  hollow  is  occupied  by  the  head;  third,  when 
the  finger  can  feel  only  one-fourth  of  the  pu])is.     Of  these  three  criteria,  the  one 


THE    MECHANISM    OF    LABOR   IN    OCCIPITAL    PRESENTATION  107 

measuring  the  distance  of  the  head  above  or  below  the  interspinous  line  is  the  most 
valuable  and  reliable. 

Engagement  varies  with  tlie  different  presentations  of  tiie  head.  It  is  ])re- 
vented  l)y  highly  contracted  j^elves,  tumors  blocking  tlie  inlet,  and  l)y  pendulous 
abdomen.  An  al)normally  large  head  engages  with  difficulty;  the  placenta  may  be 
in  the  way,  or  a  large  amount  of  liquor  amnii  (polyhydramnion)  may  confer  great 
mobility  on  the  fetus.  Whenever  the  head  does  not  engage,  the  cause  must  be 
sought  out,  and  one  may  not  operate  until  the  degree  of  engagement  is  positively 
known. 

In  the  occipitodextra  anterior  position,  the  mechanism  of  labor  and  the 
findings  are  the  same  as  in  occipitolseva  anterior,  but  reversed. 


MECHANISM  OF  LABOR  IN  OCCIPITODEXTRA  POSTERIOR  POSITION 

One  essential  difference  exists  in  the  mechanism  of  O.D.P.  as  compared  with 
O.D.A. — the  occiput  has  to  rotate  through  an  arc  of  135  degrees,  three-quarters 
of  a  half-circle,  while  in  O.D.A.  it  rotates  through  an  arc  of  45  degrees,  only  one- 
quarter  of  a  half-circle  (Figs.  225  and  226). 

Engagement  of  the  head  is  slower  because  the  broad  part  of  the  head  is  likely 
to  impinge  on  the  promontory  of  the  sacrum,  and  for  the  same  reason  flexion  is  not 
so  marked,  and  maj''  not  occur  until  the  head  is  well  down  on  the  pelvic  floor.  In- 
ternal anterior  rotation  takes  much  more  time — naturally,  since  the  occiput  has 
three  times  as  far  to  travel.  After  it  has  occurred,  the  mechanisms  of  all  positions 
are  identical.  The  factors  bringing  about  all  the  movements  are  the  same  in 
posterior  positions  as  in  anterior,  and  a  new  one  is  invoked.  It  is  believed  that  the 
shoulder,  striking  on  the  promontory  of  the  sacrum,  prevents  the  back,  and  there- 
fore the  head,  from  rotating  backward.  Sellheim  explains  anterior  rotation  l^y  his 
law  of  adaptabilitj'  of  a  body,  flexible  best  in  one  direction,  being  forced  to  accom- 
modate itself  to  the  curve  of  the  container.  Anterior  rotation  does  not  invariably 
occur — sometimes  the  occiput  rotates  to  the  hollow  of  the  sacrum  (3  per  cent,  of  the 
cases),  but  then  the  labor  is  pathologic.  This  phase  of  the  subject  is  considered  on 
p.  580. 

The  Findings  in  Occipitodextra  Posterior. — AbdominaUij,  the  back  is  felt  to 
the  right  and  posteriorly,  and  the  heart-tones  are  deeper  in  the  flank,  further  from  the 
navel.  During  labor,  both  gradually  come  anteriorly,  sinking  at  the  same  time  (Fig. 
227).  The  shoulder  is  on  the  right  side  of  the  median  line,  and  turns  to  the  front, 
then  to  the  left  side  of  the  center,  as  labor  progresses.  The  forehead,  at  first,  is 
plainly  felt  above  the  left  ramus  of  the  pubis.  It  rises  a  little  higher,  due  to  flexion 
of  the  head,  then  it  sinks  lower  as  the  head  engages;  finally,  it  sweeps  backward, 
around  the  left  half  of  the  pelvis,  disappearing  at  the  side.  The  small  parts,  feet 
and  arms,  are  felt  anteriorly  around  the  umbilicus.  InternaUy,  at  the  l)eginning 
of  labor,  the  head  is  high  up,  the  sagittal  suture  in  the  right  oblique,  the  large  fon- 
tanel in  the  left  side  anteriorly,  the  small  fontanel  high  up,  and  at  the  right  sacro-ihac 
joint.  Flexion  is  less  marked  in  these  cases.  After  descent  is  started  the  flexion 
of  the  head  throws  the  small  fontanel  nearer  the  center  of  the  pelvis,  the  large  fon- 
tanel recedes,  and  the  sagittal  suture  becomes  more  vertical.  Should  flexion  tail, 
the  head  reaches  the  perineum,  the  small  and  large  fontanels  descend  in  nearly  the 
same  plane,  the  sagittal  suture  running  more  or  less  transversely  (Fig.  230).  After 
rotation  is  complete  the  findings  are  the  same  as  in  O.D.A. 

Labor  is  always  longer,  harder,  and  more  painful,  and  effacement  and  dilatation 
of  the  cervix  not  so  complete,  in  occipitoposterior  positions.  In  j^athologic  cases 
the  powersof  labor  may  giveout  before  rotation  is  accomplished,  and  then  w(>  have  a 
condition  knoAA7i  as  "arrest,"  of  which  more  later. 

In  O.L.P.  the  mechanism  of  labor  and  the  findings  are  the  same  as  in  O.D.P., 
l)ut  reversed.

CHAPTER  XIII 
THE  MECHANISM  OF  THE  THIRD  STAGE 

Two  acts  make  up  the  delivery  of  the  placenta:  separation  or  detachment  of 
the  organ  and  its  expulsion. 

It  is  not  probable  that  the  placenta  normally  separates  as  the  trunk  of  the  child 
leaves  the  uterus.  Observations  at  cesarean  sections  show  that  the  placenta  re- 
mains adherent  to  the  uterus  during  the  first  moments  of  retraction  of  the  muscle. 
The  uterine  wall  is  thick  everywhere  but  at  the  placental  site,  which  is  nearly  as 
large  as  it  was  before  delivery  (Fig.  234).  During  the  second  stage  of  labor  the 
placenta  may  shrink  somewhat,  to  accommodate  itself  to  the  diminishing  size  of 


Placenta

its  area  of  attachment,  but  after  the  child  is  out,  the  first  uterine  contraction 
causes  such  a  diminution  of  the  surface  area  that  separation  is  inevital^le.  The 
first  break  in  continuity  allows  a  little  blood  to  escape  between  the  two  organs,  and 
the  next  uterine  contraction  forces  this  blood,  like  a  fluid  wedge,  between  the  layers 
of  the  decidua  serotina,  separating  the  placenta  in  the  smoothest  and  most  perfect 
maimer  from  the  wall  of  the  uterus.  Since  the  placenta  is  more  adherent  at  the 
edges,  the  hemorrhage  behind  it  will  lift  up  the  center,  as  is  depicted  in  Fig.  235. 
This  blood-clot  is  called  the  "  retroplacental  hemotoma,"  and  varies  much  in  size, 
depending  on  the  method  of  extrusion  of  the  placenta.  When  too  brusque  man- 
ipulations are  made  on  the  uterus,  the  edge  of  the  placenta  will  separate  at  one 

199 


200  PHYSIOLOGY    OF    LABOR 

place,  allowing  the  retroplacental  blood  to  escape  externally,  thus  producing  an 
abnormal  mechanism  of  the  third  stage. 

A  third  factor  in  the  separation  of  the  placenta,  but  a  minor  one,  is  the  loss  of 
the  intra-uterine  pressure.  There  is  now  nothing  to  hold  the  placenta  against  the 
wall  of  the  uterus. 

A  fourth  factor,  traction  on  the  placenta  by  a  too  short  cord,- — 35  cm., — or 
one  coiled  around  the  neck  of  the  child,  is  pathologic. 

Expulsion  of  the  placenta  begins  when  the  separation  is  complete,  or  nearly  so. 
The  uterine  contractions  force  the  placenta  against  the  internal  os,  and  finally, 
through  it,  into  the  dilated  cervix  and  upper  vagina.  From  this  point  another  force 
takes  up  the  work — the  abdominal  muscles.  Among  the  savages  and  ignorant 
people  various  methods  of  invoking  the  al)dominal  pressure  are  employed,  as 
coughing,  sneezing,  blowing  into  a  bottle  or  the  fist,  pushing  on  the  belly,  or  sciuat- 
ting,  as  at  stool.  The  accoucheur  directs  his  patient  to  bear  down,  which  failing,  he 
expels  the  placenta  by  pressure  on  the  uterus.     Few  authors  commend  pulling  on

the  cord.     In  pathologic  cases  an  accumulation  of  blood  may  force  the  placenta  out 
of  the  uterus. 

During  the  delivery  of  the  after-birth  one  observes  two  mechanisms:  First, 
the  placenta  turns  inside  out  like  an  umljrella,  the  fetal  surface  comes  out  first,  the 
cord  leading  the  way,  the  membranes  containing  the  retroplacental  hematoma  fol- 
lowing after.  This  is  called  Schultze's  method.  Second,  the  lower  edge  of  the 
placenta  precedes,  the  whole  organ  sliding  down  the  side  of  the  uterus  in  the  vagina. 
This  is  called  Duncan's  method.  In  the  latter  cases  the  retroplacental  hematoma 
is  small,  or  the  edge  of  the  placenta  may  have  been  inserted  low,  near  the  internal 
OS,  or  the  contractions  of  the  uterus  may  have  been  unusually  strong  from  the  start, 
quickly  separating  the  placenta  and  folding  it  together  ready  for  extrusion.  In 
opposite  conditions  we  notice  Schultze's  method.  Although  Baudelocque  described 
both  mechanisms,  they  have  been  assigned  the  above  names,  and  which  is  to  be 
considered  normal  or  more  frequent  for  a  time  occupied  the  discussion  of  authori- 
ties. My  own  observations,  with  the  cervix  exposed  by  broad  retractors,  prove 
that  a  pure  Duncan  method  is  rare,  a  combination  of  the  two  mechanisms  being 
the  rule,  but  that  the  placenta  emerges  from  the  vulva  most  often  like  an  inverted 
umbrella  (Figs.  242  and  245). 


THE    MECHANISM    OF   THE    THIRD    STAGE  201 

The  membranes  are  mechanically  drawn  off  the  wall  of  the  uterus  by  the  de- 
scending placenta,  but  the  firm  contraction  of  the  muscle  also  helps  in  their  separa- 
tion.    They  are  also  detached  in  part  l)y  the  retroplacental  hematoma,  but  when

this  is  extensive,  the  process  is  pathologic.  After  the  placenta  is  outsitle  of  the 
vulva,  the  meml^ranes  follow  to  gentle  traction  the  weight  of  the  placenta,  or  by  their 
own  weight,  if  completely  separated.  Normally,  the  membranes — consisting  of 
the  amnion,  the  chorion,  the  decidua  reflexa,  with  portions  of  the  vera  and  ]iart  of 


Fig.  239.  Fig.  240.  Fig.  241.

the  decidua  serotina — are  exiielled  still  adherent  to  each  other.  Where  the  head 
has  been  delivered  covered  with  a  "caul," — the  amnion, — a  separation  has  occurred 
between  the  chorion  and  amnion,  and  one  finds  the  latter  folded  around  the  cord,

attached  to  the  placenta  only  at  the  insertion  of  the  latter.  In  pathologic  cases 
(see  p.  772),  or  where  too  brisk  manipulations  have  been  carried  out  in  the  third 
stage,  the  placenta  is  dehvered,  leaving  more  or  less  of  the  membranes  still  attached 
to  the  uterus.     These  portions  of  the  secundines  undergo  fatty  degeneration  and

are  cast  off  with  the  decidua  during  the  puerpcrium;    or,  rarely,  they  become  in- 
fected and  cause  puerperal  fever. 

Microscopically,  one  finds  that  the  separation  of  the  placenta  and  meml)ranes 
occurs  in  the  glandular  or  ampullary  layer  of  the  decidua — sometimes  deeper, 
sometimes  more  superficially.    The  soft,  pink,  incomplete  layer  of  tissue  to  be  found

on  tho  maternal  surface  of  the  clujrion  is  dccidua  vera  and  reflexa,  and  one  can  often 
find  l)lood-vessels  in  it.  The  gray,  translucent  covering  of  the  placenta  is  dccidua 
serotina,  and  the  broken-off  veins  and  arteries  of  the  placental  site  can  always  be 
demonstrated  in  it.  These  thin-walled  vessels,  the  glandular  spaces,  and  the  ab- 
sence of  fibrous  tissue  make  the  decidua  a  very  soft  structure,  and,  therefore,  separa- 
tion of  the  secundines  is  very  easy.  One  can  rub  the  decidua  off  the  uterus  with  a 
gauze  sponge.  In  pathologic  cases  the  decidua  serotina  does  not  form,  or  is  ab- 
sorbed early,  and  the  chorionic  villi  burrow  down  into  antl  between  the  muscle-

Hemorrhage  from  the  large  sinuses  of  the  placental  site  is  controlled  by  the 
contraction  and  retraction  of  the  uterine  muscular  fibers  and  lamellae.  They  act 
like  "living  ligatures"  on  the  thin-walled  vessels  coursing  through  the  uterus.  The 
shifting  of  the  layers  of  muscle  and  shortening  of  the  bundles  of  fi])ers  disjilace,  com- 
press, twist,  and  bend  the  thin-walled  vessels,  so  that  they  are  no  longer  pervious. 
Thrombosis  in  the  sinuses  does  not  normally  occur,  but  occasionally  one  finds,  on 
the  surface  left  bare  ])y  the  ])lacenta,  a  few  thrombi  occujning  the  open  mouths  of 
the  vessels.  Thr()ml)Osis  of  the  deeper  placental  site  is  pathogenic — it  may  lead 
to  embolism  and  it  invites  sepsis.

THE  PHYSIOLOGY  OF  THE  PUERPERIUM 


CHAPTER  XIV 
LOCAL  CHANGES 

With  the  completion  of  the  third  stage,  labor  is  ended;  the  puerperal  state 
or  puerperiuni  has  begun;   the  woman  is  a  puerpera. 

The  puerperium  may  be  defined  as  that  period  which  extends  from  the  de- 
livery of  the  ovum  until  the  return  of  the  genitalia  to  the  non-pregnant  is  complete. 
Its  length,  therefore,  is  from  six  to  eight  Aveeks,  though  in  common  usage  the  puer-

])erium  means  the  time  the  woman  is  in  l)ed  after  the  labor.  As  has  l)een  repeatedly 
stated,  a  perfect  restitutio  ad  integrum  never  occurs  after  labor.  The  woman 
carries  the  evidences  of  child-bearing  all  her  life.  The  distinction  between  normal 
and  pathologic  conditions  during  the  puerperium  is  not  easy,  even  with  the  aid  of 
the  thermometer  and  of  bacteriology.     The  rapid  cUsintegration  of  the  uterus,  the

changes  in  the  endometrium,  and  in  the  open  vessels  at  the  placental  site,  are 
closely  akin  to  the  pathologic,  and  would  \h'  called  such  if  they  occurred  at  any  other 
time  or  i)lace.  It  is  the  same  approach  to  the  aljnormal  that  renders  permanent 
structural  disease  so  prone  to  begin  during  the  puerperal  period. 

In  the  physiology  of  pregnancy  we  learned  of  all  the  changes,  local  and 
general,  which  provided  for  the  growth  of  the  child  and  its  exi)ulsion  from  the 
mother.  These  were  progressive  changes.  In  the  physiology  of  the  pucrpcrium 
we  will  study  the  retrogressive  changes,  local  and  general,  which  bring  back  the

•organs  of  the  mother  to  their  original  condition,  and,  second,  those  progressive 
changes  in  the  breasts  which  enable  them  to  carry  further  the  function  liegun  by 
the  uterus— the  nourishment  of  the  child.  The  retrogressive  changes  of  the  geni-

Changes  in  the  Uterus. — Immediately  after  delivery  of  the  placenta  the  uterus 
sinks  below  the  level  of  the  navel  in  strong  anteversion  and  anteflexion,  resting  on 
the  promontory  ])ehind  and  lying  against  the  abdominal  wall  in  front  (Fig.  247). 
Owing  to  its  previous  displacement,  its  ligaments  and  vaginal  attachments  are  so 
loose  that  the  fundus  may  easily  be  moved  to  any  part  of  the  belly, — even  as  high  as

THE    PHYSIOLOGY    OF    THE    PUERPERIUM 


the  liver,  or  may  be  pushed  down  so  that  the  ('er\ix  hangs  out  of  the  vulva.  The 
full  bladder  always  displaces  the  uterus,  and  usually  the  latter  rises  toward  the  right 
side.  The  uterus  now  resembles  a  flattened  pear;  it  is  15  cm.  long,  12  cm.  broad, 
and  8  to  10  cm.  thick,  being  about  as  large  as  a  fetal  head,  and  it  weighs  about  two 
pounds.  On  vaginal  examination  immediately  after  labor  one  can  hardly  outline 
the  cervix,  it  is  so  soft  and  succulent,  hanging  down  from  the  hard  contracted  mus- 
cular fundus  in  folds,  like  a  cuff.  It  is  about  1  cm.  thick  and  6  or  7  cm.  long,  but 
may  be  stretched  to  10  or  11  cm.  The  internal  os  or  contraction  ring  firmly  closes 
the  uterine  cavity  and  marks  the  point  where  the  thick  fundus  goes  into  the  thin

lower  uterine  segment  and  cervix.  Either  a  small  blood-clot  fills  the  cavity  of  the 
uterus  or  the  walls  lie  apposed.  At  the  placental  site  the  uterine  wall  is  thinner 
than  elsewhere  until  a  few  contractions  have  occurred ;  then  it  is  thicker,  and  one 
recognizes  the  location  of  the  placenta  by  the  roughened,  raised  surface.  This 
roughened,  raised  surface  is  normal,  and  must  not  be  mistaken  for  a  piece  of  ad- 
herent placenta.  Measurements  by  Fehling  show  the  thickness  of  the  wall  to 
vary  from  33^  to  5  cm. 

Owing  to  the  development  of  the  elasticity  of  the  vagina  and  pelvic  floor,  and 
the  filling  of  the  rectum  and  l)ladder,  the  uterus  rises  in  the  abdomen  on  the  first 
day  of  the  puerperium;    but  from  then  on  one  observes,  from  day  to  day,  a  steady

While  one  may  follow  the  descent  of  the  uterus  with  the  tape-measure,  for  prac- 
tical purposes  the  rule  of  the  fingers  is  sufficient.  On  the  first  day  the  uterus  is 
seven  or  eight  fingerbreadths  above  the  pubis;  on  the  fifth  day  four  or  five,  and  cor- 
respondingly narrower  acro.ss  the  fundus;  while  by  the  tw(>lfth  day  it  has  sunk  be- 
low the  inlet  so  that  it  is  not  easily  palpable  from  thealulomen  (Figs.  249  and  250). 


208  THE    PHYSIOLOGY    OF    THE    PUEKPERIUM 

After  delivery  the  uterus  weighs  2^  pounds,  or  1000  gui.;  by  the  end  of  the 
first  week  it  has  lost  one-half — 500  gm.;  at  the  end  of  the  second  week  it  weighs 
350  gm.  (about  11  ounces);  while  in  the  eighth  week  it  again  is  the  small  organ  of 
two  ounces,  or  60  gm. 

This  rapid  diminution  of  size  is  brought  about  by  absorption  of  the  tissue-juices 
and  fatty  degeneration  of  the  muscle-fibers.  Sanger  showed  that  th(»  fibers  are 
not  all  nor  fully  destroyed,  but  the  protoi:)lasni  undergoes  cloudy  swelling,  hyaline 
and  fatty  tlegeneration.  The  fat  is  removed  b}^  the  lymph-stream,  by  oxidation, 
by  the  action  of  a  fat -splitting  ferment,  and  partly  by  the  leukocytes.  That  fatty 
degeneration  of  the  muscle  protoplasm  is  not  the  only  method  nature  has  for  re- 
ducing the  uterus  is  indicated  by  the  demonstration  of  glycogen  (Broers)  and  pep- 
tone (Hofmeister)  in  the  muscle.  The  connective-tissue  fibers  also  undergo  hya- 
line fatty  degeneration  and  partial  absorption.  A  multiparous  uterus  is  usually 
thicker  and  more  fibrous.     Little  is  known  of  the  changes  in  the  nerves. 

The  uterine  vessels  are  compressed  by  the  contracting  uterus,  causing  the 
anemia  which  is  the  basal  factor  of  the  changes  described  above,  and  obliterating 
the  vessels  themselves,  with  hyaline  and  fatty  degeneration  of  their  walls  and 
occlusive  groAvth  of  the  endothelium  (E.  Ries).  Thrombosis  occurs  in  the  walls  of 
the  deeper  veins  only  in  pathologic  cases,  but  a  superficial  thrombosis  is  not  ab- 
normal, and  may  occur,  according  to  Leopold,  even  in  the  latter  weeks  of  pregnancj'. 
These  thrombi  are  organized  in  the  usual  manner  during  the  puerperium.  The 
placental  site,  after  the  placenta  has  left  it,  contracts  rapidly,  presenting  a  raised 
and  nodular  surface  about  three  inches  in  diameter;  by  the  fourteenth  day  it  is 
the  size  of  a  silver  dollar,  and  in  six  weeks  may  still  be  recognized  by  its  elevated, 
though  not  roughened,  surface,  which  is  the  size  of  a  quarter. 

The  uterine  serosa,  in  spite  of  its  elasticity,  cannot  follow  the  receding  uterus. 
It  lies  in  fine  ^ATinkles  w^hich  are  well  sho^vn  in  Fig.  125,  p.  95.  They  disappear 
within  a  week.  Their  distinctive  grouping  shows  the  direction  of  the  contraction 
of  the  muscle-fibers. 

The  cervix,  after  labor,  hangs  down  like  a  soft  cuff,  succulent,  bruised,  some- 
times almost  black  Avith  suffused  blood,  edematous,  and  more  or  less  torn.  The 
author  has  never  failed  to  find  more  or  less  injury  to  this  organ,  even  after  natural 
and  easy  labors.  The  serous  infiltration  disappears  rapidly,  and  within  eighteen 
hours  the  cervix  forms,  quickly  shortens,  and  becomes  harder.  On  the  third  day 
two  fingers  still  pass  easily  into  the  uterus;  on  the  twelfth  da,y  one  finger  can  attain 
the  internal  os,  but  cannot  go  through  it;  while  in  the  fourth  week  the  os  is  a  small 
transverse  slit. 

Changes  in  the  Endometrium.— During  pregnancy  the  glandular  layer  of  the 
decidua  vera  and  serotina  undergoes  a  fatty  degeneration.  The  separation  of  the 
placenta  and  membranes  takes  place  in  this  layer;  therefore,  when  the  uterus  is 
emptied,  its  mucous  surface  is  denuded,  the  connective-tissue  spaces  being  ex- 
posed all  over,  and,  at  the  placental  site,  almost  to  the  muscle.  The  interior  of  the 
uterus  is  one  large  w^ound,  with,  at  the  placental  site,  immense  veins,  containing 
superficial  throml)i,  opening  upon  it.  This  condition  explains  the  ease  of  infection 
and  the  severity  of  the  disease  if  it  once  gains  entrance.  An  invasion  of  the  decidua 
by  white  blood-corpuscles  takes  place,  forming  a  layer  of  granulation,  which  sepa- 
rates the  necrosing  parts  of  the  decidua  from  the  healthy.  At  first  the  endome- 
trium varies  from  2  to  5  mm.  in  thickness,  the  surface  is  rough,  with  shreds  of 
degenerating  decidua,  blood-clots,  and  bits  of  fetal  memljrane.  By  the  third  daj^ 
this,  as  the  result  of  fatt}^  degeneration,  has  softened  so  that  it  could  be  wiped  off 
with  the  finger,  but  nature  accomplishes  it  in  a  better  way.  The  granulation  wall 
separates  the  dead  from  the  living  tissues,  the  remaining  decidua  cells,  in  part, 
return  to  their  original  condition,  the  epithelium  from  the  stumps  of  the  glands 
which  lay  unaffected  among  the  muscle-fibers  and  whic^h  now  crowd  closer  together

as  the  uterus  shrinks,  proliferates  rapidly,  grows  out  on  the  surface  of  the  endome- 
trium, and  covers  the  new  mucous  membrane.  Thus  the  lar^^er  j)art  of  the  endo- 
metrium is  cast  off,  regeneration  taking  place  from  the  connective-tissue  basis  of 
the  mucous  membrane  and  from  the  epithelium  of  the  deepest  portions  of  tlie 
utricular  glands  (Fig.  2.")1).  It  closely  resembles  the  healing  of  a  granulating  sur- 
face on  anv  nmcous  membrane.

At  the  placental  site  similar  processes  occur,  with,  in  aildition,  the  thrombosis

slower  tiian  in  tlie  vera. 

Changes  in  the  Vagina  and  External  Genitalia.— .\fter  labor  the  vagina  may 

be  found  swollen,  blue,  bruised,  pouting  into  the  vulva;  but  it  soon  regains  most 

of  its  tonicitv.  though  onlv  after  years  to  a  degree  approaching  normal.     The 

extravasated  blood  is  absorfjed  in  a  week,  the  prolapse  of  the  walls  becomes  less, 

U 


210  THE    PHYSIOLOGY    OF   THE    PUERPERIUM 

though  the  anterior  wall  of  the  vagina  usually  remains  permanently  lower.  The 
elasticity  of  the  perineum  is  reestablished  with  surprising  rapidity;  perineal  tears 
that  looked  large  and  deep  are  small  the  next  day,  but  just  as  important,  however. 
A  peculiar  consistence  of  the  vagina  and  perineum  remains  for  weeks  after  delivery. 
The  tissues  are  distensible  to  only  a  certain  degree,  after  which  they  break  like 
card-board;  the  blood-vessels  are  friable,  and  operations  performed  during  the 
puerperiura  are  likely  to  be  complicated  by  troublesome  capillary  oozing.  Many 
cases  of  rupture  of  the  vagina  sub  coitu  have  been  reported  as  occurring  in  this 
period,  and  bleeding  is  always  a  prominent  sjTiiptom.  The  vagina  and  mucous 
surface  of  the  vulva  have  a  deep-red,  velvety  appearance,  by  which  the  puerperal 
state  can  usually  be  diagnosed. 

The  pelvic  floor,  containing  muscle,  fat,  and  fascia,  is  infiltrated  with  bloody 
serum,  full  of  small  suggillations,  even  some  larger  blood  extravasations.  The 
muscle-fibers  are  often  torn  and  overstretched.  Aljsorption  of  the  blood  and 
serum  quickly  takes  place,  but  many  minute  and  larger  scars  are  left,  which  result 
in  atrophy  and  a  weakened  pelvic  floor. 

The  Puerperal  Wounds. — A  study  of  the  healing  process  of  the  wounds  made 
by  labor  forms  an  essential  part,  of  the  duties  of  the  accoucheur.  The  hymen 
tears  in  every  labor,  and  its  relics  are  found  as  a  row  of  mucous  membrane  tags 
circling  the  vaginal  orifice  and  called  carunculce  myrtijormes.  Around  the  clitoris, 
the  labia  minora,  the  introitus  vaginte,  in  the  vagina,  in  the  cervix — especially  in 
primiparge— occur  larger  or  smaller  lacerations,  bruises,  and  scraped  surfaces. 
These  may  heal  by  apposition  and  primary  union,  or  by  granulation  and  suppura- 
tion. Lacerations  of  the  perineum  occasionally  heal  by  primary  union,  but  usually 
granulate  up  from  the  bottom.  Sometimes  the  skin  unites,  but  the  body  of  the 
perineum,  the  physiologically  important  part,  does  not  unite  well.  Lacerations 
of  the  vagina  usually  heal  readily,  but  with  scar  formation,  which,  if  marked,  will 
distort  the  base  of  the  bladder,  producing  incontinence  of  the  urine,  or  dislocate  the 
uterus,  producing  sterility  and  other  noxious  conditions.  Cervix  tears  occasionally 
unite  by  primary  union.  If  infected  they  do  not,  but  may  give  rise  to  cellulitis  in 
the  adjacent  broad  ligaments,  with  resulting  life-long  invalidism. 

In  the  absence  of  infection  these  wounds  heal  with  very  little  inflammatory 
reaction.  The  surface  is  covered  with  a  light-gray  exudate.  Underneath  this 
pink,  pointed  granulations  appear,  the  surface  cleans  off,  epithelization  rapidly 
occurs,  and  by  the  eighth  day  is  usually  nearly  completed.  Abnormal  wound  repair 
indicates  infection  somewhere  in  the  parturient  canal.  Swelling  of  the  labia, 
edema  around  the  wounds,  which  have  a  reddened,  angry  aspect,  greenish,  yellow- 
ish, even  dark  sloughing  of  the  surface  of  the  wounds,  pain,  fever,  and  illness,  indi- 
cate that  the  normal  process  is  being  interfered  with  by  infection. 

The  Lochia. — Another  striking  phenomenon  of  the  puerperium  is  the  appear- 
ance of  the  lochia,  a  discharge  from  the  genitalia  at  first  blood}',  then  sanguineous, 
then  purulent,  finally  mucoserous,  before  ceasing  entirely,  in  three  to  six  weeks. 
On  the  first  day  the  lochia  are  almost  pure  blood,  normally  not  mixed  with  clots — 
lochia  cruenta  or  rubra.  Clots,  unless  large  and  numerous,  are  not  significant. 
This  flow  is  followed  by  one  of  blood-stained  serum,  which  lasts  a  day  or  so,  after 
which  the  discharge  is  thicker,  of  a  maroon  color  and  creamy  consistence,  with  a 
characteristic  odor — lochia  sanguinolenta.  Gradually  the  bloody  admixture  grows 
less,  the  white  blood-corpuscles  increase,  the  lochia  resemble  cream, — lochia  alba  or 
purulenta, — until  at  the  end  (thirteenth  to  the  seventeenth  day)  there  is  only  a  slight 
mucoserous  discharge. 

The  odor  of  the  lochia  varies  from  day  to  day,  varies  with  the  patient,  some 
women  naturally  possessing  a  peculiar  odor  (even  with  the  menses),  and  with  the 
kind  of  bacteria  present  in  the  vagina.  Normally,  the  odor  is  not  very  offensive, 
being  faded  or  insipid,  like  old  meat,  or  strong,  like  perspiration.     If  the  lochia  are

of  the  severer  types  of  infection.

mucus  from  the  cervix  and  vagina,  and  microorganisms  (Fig.  252). 

Lochia  alba  an^  full  of  decidual  cells — large  mononucleated,  irregular,  round 
or  spindle-sliape(l  i-eils  in  process  of  degeneration,  leukocytes,  "lochiocytes,"  flat  and 
cylindric  epitiielium,  fat  and  <lebris  from  the  uterus  and  the  puerperal  wounds, 
mucus,  cholesterin  crystals,  the  Trichomona's  vaginalis,  and  myriads  of  microorgan- 
isms (Fig.  254). 

The  Bacteriology  of  the  Lochia. — Even  in  normal  puerperse  the  lochia  are  in- 
fectious, as  the  frecjuent  finger  infections  of  nurses  and  the  navel  infections  of 
children  show.  Kehrer  vaccinated  j)ueri)eriP  on  the  thigh  with  their  own  lochia 
and  protlucetl  abscesses.  Likewise,  inoculations  of  animals  with  normal  lochia,  in 
many  cases,  produced  sepsis  and  death.  Doderlein  found  that  the  uterus,  in  the 
first  few  days  after  labor,  was  sterile  in  83  per  cent,  of  250  ca.ses  examined.  In 
the  others  were  found  the  streptococcus,  the  stai)hylococcus,  the  gonococcus, 
and  various  saprophytes,  aerobic  and  anaerobic.  The  vaginal  lochia  also  con- 
tain these  bacteria,  and  in  greater  frequency  and  numl)er  after  the  first  day 
of  the  puerperium.  The  uterus,  from  the  fourth  to  the  seventh  day,  shows  a 
bacterial  flora,  including  the  streptococcus  pyogenes  (Scheib).  In  the  succeeding 
week  tile  uterus  gradually  becomes  aseptic.  The  most  imjwrtant  bacteria  founii 
in  the  lochia  are  the  .streptococcus,  the  staphylococcus,  and  the  bacillus  coli  com- 
munis.    (See  chapter  on  Puerperal  Infection.) 

In  spite  of  very  extensi^■e  study  and  experimentation,  it  is  yet  impossible  to 
distinguish  the  i)athogenic  from  the  non-jiathogenic  streptococcus.  Therefore  the 
streptococcus,  found  in  the  vagina  of  gravida'  and  puerpera*,  must  be  regartled  as 
capable  of  developing  destructive  qualities  if  the  conditions  for  it  are  ripe. 

Since  there  is  no  doubt  of  the  presence  of  these  dangerous  germs  in  the  vagina, 
why  is  it  that  women  do  not  all  develop  fever  or  infection  tluring  the  i)uerperium? 

First,  because  tiie  l)acteria  do  not  wander  U))ward  into  the  uterus,  where  the 
most  extensive  wounded  surface  lies,  until  the  tliird  or  fourth  day,  and  by  this 
time  the  protecting  granulation  wall  is  formed  in  the  endometrium.  The  stream 
of  lochia  from  above  tends  to  wash  them  out.  The  thick,  squamous  epithelium 
of  the  vagina  also  acts  protectingly  against  an  invasion  by  bacteria.  If  a  care- 
less examiner,  or  indeed  any  manii)ulation,  breaks  tiu-ough  this  i)rote(ting  wall  of 
granulations,  the  infection  of  the  underlying  l)lood-and  lymi)h-ves.sels  is  inevital)le. 
Clinical  experience  has  taught  us  the  danger  of  such  interference. 

Second,  because  the  bacteria  are  of  weak  virulence,  or — and  this  is  proliably  a 
complement  to  sucli  a  .statement — the  jiuerj^era  ]ias.ses.ses  natural  inununities 
against  infection.  When  her  general  health  is  broken.— as  by  hemorrhage  or 
edamjisia,  shock  from  operation, — or  if  the  local  resistances  are  lowen-d  from  i^evere 
injury,  the  bacteria  can  develop  their  virulence  and  invade  her  organi.snu  Anal- 
ogously, the  bacterium  coli  communis  in  the  intestine  and  the  bacillus  diphtheria*  in 
the  mouth,  may  live  for  years  without  j^roducing  disease.  Perhaps  part  of  this 
immunity  lies  in  the  presence  of  other  bacteria  in  the  vagina,  and  part  in  the  acid 
reaction  of  the  secretion  (after  the  sixth  day);  but  most  of  it,  probably,  is  in  the 
active  immune  bodies  of  the  living  tissues  themselves  (Stoltz,  Williams). 


212  THE    PHYSIOLOGY    OF   THE    PUERPERIUM 

The  Quantity  of  the  Lw/jm.— Hippocrates  estimated  the  amount  of  the  lochia  to 
be  about  1300  gm.;  later  authors  place  it  at  alwut  500  gm.,  throe-fourths  of 
which  is  discharged  in  the  first  four  days,  ^^'onlen  who  do  not  nurs(^  their  babies 
have  more,  nursing  women  less;  indeed,  in  the  latter,  involution  is  faster  and  more 
perfect.  These  conditions  are  attended  with  increase  of  the  lochia:  Primiparity; 
young  women;  women  who  usually  have  profuse  menses;  Uvins;  large  placenta; 
severe  operative  deliveries,  with  l)ruising  and  injuries  of  the  genitalia;  retention  of 
parts  of  placenta  and  nieml)rane;  too  full  meat  (Uet;  alcoholism;  hemophilia; 
general  atony.     A  strong,  robust  woman  has  more  rapid  rejiarative  processes. 

Source  of  the  Lochia. — The  lochia  are  very  complex,  containing  the  wound  dis- 
charges, a  serosanguineous  exudate  from  all  the  puerperal  wounds,  from  those  of  the 
emlometriura,  the  lacerations  of  the  cervix,  indeed,  of  the  whole  partm-ient  canal. 
A  part  of  the  flow  comes  from  the  utricular  glands,  the  cervical  glands,  the  vaginal 
and  \ailvar  glandular  organs. 

The  amount  and  quality  of  the  lochia  vary  from  day  to  day.  If  the  patient 
sits  up  early,  the  lochia  sanguinolenta  continue  longer  or  are  more  profuse.  Some- 
times the  red  lochia  persist  for  several  weeks,  or  they  may  reappear  on  the  occasion 
of  unusual  exercise;  or  the  lochia  may  cease  as  the  result  of  disease  (infection)  or  of 
obstruction  to  the  flow.  This  almost  always  causes  fever,  which  subsides  when  the 
drainage  is  reestablished.  The  normal  changes  in  the  color  and  consistence  of  the 
lochia  are  interfered  ^^^th  by  infection,  and  one  of  our  best  diagnostic  means  is  the 
investigation  of  the  puerperal  discharges.  The  lochia  contain  a  leukocyte  proteo- 
lA>i:ic  ferment  (Jochman). 

Involution. — All  the  foregoing  changes  are  part  of  the  function  of  involution, 
the  most  prominent  of  which  is  the  reduction  in  size  of  the  uterus.  The  reduction 
in  size  of  tlie  uterus  is  subject  to  man}'  variations.  In  women  who  do  not  nurse, 
the  reduction  in  size  is  slower.  Sepsis  stops  involution  or  slows  it — an  important 
sign.  On  the  other  hand,  involution  offers  a  barrier  to  infection — the  shedding  of 
the  decidua  resembles  the  cleansing  of  a  granulating  surface;  the  lochia  carry  off 
the  germs.     The  tightly  contracted  uterus  does  not  absorb  bacteria  nor  toxins. 

Involution  varies  in  different  women  and  in  the  same  woman  after  different 
confinements.  The  rate  of  decrease  is  not  even,  the  greatest  being  during  the  first 
six  days.  Sometimes  the  process  goes  beyond  the  normal,  the  uterus  at  the  tenth 
VN^eek  being  very  small — 'superinvoluted.  This  superinvolution  is  sometimes  called 
"lactation  atrophy."  It  occurs  only  in  women  who  nurse,  and,  in  such  cases,  the 
periods  do  not  reappear  during  lactation.  The  atrophy  reaches  its  maximum  about 
the  fourth  month.  If  nursing  is  stopped,  the  uterus  is  regenerated  in  six  to  eight 
weeks.  This  phenomenon  is  probably  a  conservative  act  of  nature  agamst  too 
frequent  pregnancies.  If  the  nursing  is  continued  too  long,  actual  atrophy  of  the 
uterus  may  occur.  AVhen  there  are  no  general  sjiiiptoms, — as  pain  in  the  back, 
nervous  disturbances,  anemia,  weakness, — and  if  the  uterus  does  not  grow  too  small, 
the  condition  is  not  abnormal,  and  the  uterus  will  regain  its  size  after  lactation 
ceases;  sometimes,  even  before  this.  Occasionally  (60  per  cent.),  about  the  third 
or  fourth  week,  there  is  a  slight  return  of  l)loody  lochia.  This  is  usually  due  to  too 
much  activity  of  the  j^atient,  and  the  blood  comes  from  the  placental  site;  perhaps 
a  superficial  clot  is  being  exfoliated.  A  piece  of  placenta,  thick  membranes,  sub- 
involution, infection  of  the  endometrium,  fibroids,  and  retroflexion  are  the  com- 
monest causes  of  profuse  and  abnormally  long-continued  lochia,  or  of  a  return  of 
l)loody  discharge.  An  early  return  of  the  menses  occurs  in  43  per  cent,  of  nursing 
women,  but  in  only  26  per  cent,  are  the  periods  regular.  Intervals  of  weeks  and 
months  are  noted,  as  are  also  great  irregularities  in  amount  and  duration.  If 
the  women  do  not  nurse,  the  menses  usually  return  in  six  weeks  and  continue  more 
or  less  regularly.  The  first  menstruation  after  delivery  is  likely  to  be  profuse. 
The  Abdominal  Walls. — In  many  women  the   abdominal  walls  very  slowly 


LOCAL    CHA.N<.K.>  213 

and  iiniK'rfof'tly  regain  tlicir  jjrcvious  elasticity.  In  but  a  few  the  tonus  is  well 
preserved.  A  great  deal  depentls  on  the  amount  of  distention  of  the  ahdonien 
during  gestation  and  the  development  of  gas  in  the  bowels  after  labor,  ^^'earing 
tigiit  corsets  during  pregnancy  predispo.ses  to  weakness  of  the  abdominal  nmscles. 
Attention  to  tiie  bowels  i)()sti)artum,  and  to  the  strengthening  of  the  nm.scles,  will 
aid  in  i)reventing  what  the  women  call  "high  stcjmach."  Sometimes  the  l)elly  is  .so 
weakened  that  the  recti  separate  and  the  uterus  comes  to  lie  between  them,  a 
state  which  the  women  call  ''rupture,"  the  scientific  term  being  diastasis  recti. 

Changes  in  the  Breasts. — These  consist  in  the  establishment  of  the  function  of 
lactation,  whcrelix  the  woman  is  put  in  i)osition  to  continue  the  nourishment  of  her 
offspring. 

Nature  has  made  woman  an  excejjtion  to  the  rule  of  other  mammals.  In  her 
the  secretion  of  milk  does  not  l)egin  until  the  second  or  third  day,  rarely  on  the  first 
day  after  birth.  In  animals  tlie  milk  is  jiresent  in  the  glands  the  first  few  Injurs — 
even  during  labor.  This  delay  is  j)ossil)ly  an  outgrowth  of  civilization,  in  tliat 
the  function  of  reproduction  is  not  allowed  such  full  i)lay  as  formerly,  and  lactaticjn 
especially  has  been  neglectetl  for  generations,  resulting  in  hypoplasia  of  the  glands. 

The  changes  about  to  be  descrilx'd  occur  in  the  brea.sts  after  abortions  from  the 
fourth  month  on,  as  well  as  after  labors  at  term.  On  the  second  day — or,  a.s  is 
usual  in  primipara",  on  the  thiril  day — the  breasts  grow  harder,  the  veins  become 
prominent,  the  whole  organ  fuller  and  heavier;  the  patient  has  the  feeling  that  the 
secretion  of  milk  is  beginning  and  descril)es  a  prickling  or  burning  sensation.  Soon 
the  swelling  reaches  a  considerable  degree,  and  tlie  individual  milk-<lucts  can  be 
felt  :us  hard  strings — the  lobes  of  the  breasts  as  liard  lumps.  The  gland  is  much 
fuller  with  blood  and  feels  hot  to  tlie  touch.  Rarely,  it  becomes  reddenecl  and 
sometimes  there  is  a  bluish  turgescence  of  the  surface.  The  milk  comes  into  the 
breasts  much  more  stormily  in  jjrimiparae;  they  express  it  as  "shooting  in,"  and 
the  distress  caused  is  S(jmetimes  very  .severe. 

The  woman  says  the  breasts  feel  like  two  hot  weights  on  her  chest,  and  if  the 
little  extension  of  the  gland  which  sometimes  lies  in  the  axilla  is  involved,  the  })a- 
tient  keeps  her  arms  outstretched  in  consideraljle  discomfort,  if  not  pain. 

Tlu!se  ])henomena  are  attended  with  a  slight  flow  of  milk  from  the  l)reasts, 
even  if  the  baby  iloes  not  nurse.  At  each  nursing  the  milk  comes  with  greater 
force,  but  after  twenty-four  hours  the  process  is  not  so  active,  though  there  may 
still  l)e  too  nmch  milk  for  a  week,  the  binder  being  always  more  or  less  wet  with  it. 
Les.ser  degrees  of  activity  of  the  breasts  are  connnon,  even  agalactia,  absence  of 
lactation,  Ix'ing  observed.  Even  though  the  l)reasts  show  tumor,  dolor,  calor.  an«l 
rul)or,  the  phenomenon  has  nothing  to  ilo  with  intianuuaticjn;  the  jjatient  has  no 
temperature,  or,  at  most,  one-half  degree  F.  There  is  nothing  that  could  l>e  called 
"milk  fever. " 

In  nuiltiiJane  the  secretion  begins  earlier,  sometimes  even  in  tiie  twelve  hours 
after  labor,  and  the  brea.sts  do  not  take  on  such  sudden  action.  l)Ut  lactati(»n  begins 
more  gradually,  and  seldom  do  the  breasts  swell  .so  that  the  skin  is  stretched  over 
them  tightly,  as  in  primipara*. 

The  enlargement  of  the  brea.sts  is  not  due  wholly  to  milk.  Only  a  small  part, 
of  the  milk  is  formed  l)efore  the  nur.sing,  most  being  made  while  the  child  is  suckling. 
The  di.stention  of  the  breasts  is  due  to  swelling  of  the  gland-cells  and  lymi)hatic 
engorgement — both  preparatory  to  the  formation  of  milk.  As  s<x)n  as  the  child 
liegins  to  nurse  the  gland-cells  break  down  into  fat-glol)ules,  the  cells  pro<luce  the 
milk  i)lasma  from  the  lymi)h  in  the  distended  lymphatics,  and  active  secretion  is 
established  in  a  manner  somewhat  analogous  to  the  action  of  the  parotid  gland. 
Completely  established,  the  milk  secretion  becomes  regular.  The  breasts  fill  up 
and  are  emptied  in  sequence,  which  is  dependent  largely  upon  training.  If  the 
child  is  put  to  the  breast  to  nurse  at  regular  intervals,  the  organ  quickly  accom- 


214  THE    PHYSIOLOGY    OF   THE   PUERPERIUM 

modates  itself  to  the  hours,  and  one  notices  that,  when  the  usual  sequence  is  in- 
terrupted, the  breast  will  begin  to  functionate  at  the  proper  time. 

The  first  milk  that  comes  resembles  the  secretion  that  may  be  pressed  out  of  the 
nij^ple  in  the  latter  jiart  of  pregnancy;  it  is  clear  or  only  slightly  cloudy,  sticky,  eon- 
tains  yellow  streaks,  and  is  called  "colostrum." 

The  colostrum  under  the  microscope  is  seen  to  be  made  up  of  fat-globules,  a 
watery  fluid,  and  the  so-called  colostrum  corjiuscles  (Fig.  255).  The  fat-globules 
are  often  atlherent  by  a  thin  substance  which  is  visible  after  staining  with  certain 
reagents.  The  colostrum  corpuscles  are  round,  ovoid,  or  stellate  cells  which  some- 
times show  ameboid  movement  and  have  one  to  three  nuclei,  which  color  with 
ammonia  carmin.  They  contain  numerous  fine  fat-globules.  Where  they  come 
from  has  lieen  disputenl — they  are  believed  to  be  changed  gland  eiaithelium  or  leu- 
kocN'tes,  mast  cells  which  have  gathered  up  fat-globules.  They  remain  four  to  six 
days,  and  reappear  if  there  is  stasis  or  inflammation.  In  addition,  Ijanphocj'tes  are 
found,  more  or  less  full  of  fat  drops;  indeed,  they  may  be  balled  together  so  that 
they  can  hardly  be  recognized  as  white  blood-cells.  Colostrum  contains  very  little 
if  any  casein,  but  nearly  15  per  cent,  lactalbumin  and  lactoglobulin,  with  much  fat. 
It,  therefore,  has  a  slightly  cathartic  action  on  the  new-born  babe.  One  sometimes 
finds  colostrum  in  the  breasts  during  menstruation,  sexual  excitement,  always 
during  pregnancy,  early  lactation,  and  during  the  weaning  process.  The  colostrum 
at  this  time  helps  the  resorption  of  the  milk. 

Human  milk  is  an  opaque,  slightly  j^ellowish  or  bluish-white  liquid,  with  a 
characteristic  odor  and  sweetish  taste.  Specific  gravity  varies  from  1026  to  1036; 
it  is  neutral  or  alkaline;  its  freezing-point  is  A=  —0.49  to  —0.63.  Microscopic- 
ally, one  sees  innumerable  fine  fat-droplets,  alike  in  size  if  the  milk  is  of  good 
quality,  and  occasionally  a  glandular  epithelial  cell  or  a  leukocyte. 

It  is  still  unsettled  whether  there  is  a  membrane  of  casein  around  the  fat-glob- 
ules or  not.  The  globules  float  in  a  thin,  almost  transparent,  serum  which  con- 
tains albumin.     Sometimes  bacteria  are  present. 

The  composition  of  human  milk  varies  from  day  to  day  and  from  hour  to  hour. 
It  contains  <S73  2  per  cent,  water,  12}/^  per  cent,  solids,  of  which  6.21  per  cent,  is 
milk-sugar,  3.78  per  cent,  fat,  2.29  per  cent,  proteids  (lactoglobulin,  1.26  per  cent., 
and  casein,  1.03  per  cent.),  and  0.71  per  cent,  salts  (Konig).  Of  these  constituents, 
the  fat  is  subject  to  the  greatest  variations,  the  proteids  less,  while  most  constant 
are  the  sugar  and  salts.  In  round  figures,  milk  has  88  per  cent,  water,  2  per  cent, 
proteids,  4  per  cent,  fat,  and  6  per  cent,  sugar.  The  fat  of  the  milk  comes  from  the 
epithelium  lining  the  acini  and  alveoli.  When  the  proper  stimulus  reaches  these 
cells,  which  are  low,  cuboid,  with  one  nucleus,  they  enlarge,  the  nucleus  divides 
in  a  vertical  direction,  the  cell  becomes  columnar,  the  protoplasm  shows  fat-glob- 
ules, esi:)ecially  near  the  lumen  of  the  acinus,  and  finally  the  cell  membrane  breaks, 
setting  free  the  formed  fat.  After  this  process  is  repeated  several  times  the  cell 
itself  is  cast  off,  its  place  being  taken  by  others  made  by  lateral  proliferation  (Figs. 
257  and  258).  It  is  possible,  but  not  proved,  that  the  epithelia  can  select  fat  out  of 
the  circulating  blood,  or  make  it  from  the  carbohydrates  ever  present  in  the  gland. 
The  casein,  since  it  does  not  exist  in  the  blood,  must  be  made  in  the  gland  itself,  as 
also  must  be  milk-sugar  or  lactose.  Bottazzi  found  a  phosphoglycoproteid  in  the 
breast,  and  believes  that  through  the  splitting  of  this,  casein  and  lactose  result.  If 
there  is  stasis  of  milk  in  the  breasts,  lactose  appears  in  the  urine. 

The  fluid  parts  of  the  blood  do  not  reach  the  milk  by  filtration  or  exudation,  but 
are  secreted  from  the  blood  by  special  action  of  the  glandular  epithelium.  One 
must  accord  the  epithelium,  then,  the  most  important  function  of  making  the  milk. 

Enzymes,  or  living  ferments,  are  found  in  the  milk  and  give  it  vital  sustaining 
qualities,  which  are  not  to  be  discovered  or  imitated  by  the  finest  chemistry. 
Breast  milk  is  a  living  secretion,  and  contains  all  the  food  requirements  for  the  in-

fed  artificially.  The  author  has  seen  such  children,  brought  to  the  hospital  in

stronger  bactericidal  power  than  that  of  those  fed  from  the  Iwttle.  The  quantity 
and  quahty  of  the  milk  vary: 

First,  with  the  individual — nervous  women  ar(>  not  as  good  wet-nurses  as  the 
plilegmatic. 

Secontl,  witli  the  race— Japanese,  Jews,  Swedes,  Turks,  gypsies,  and  negresses 
usually  have  abundant  milk. 

Third,  with  development  of  the  body — a  small,  thin  woman  usually  gives 
more  milk  than  a  large,  muscular,  or  fat  woman;  the  same  rule  holding  good  with 
cows.  Nor  does  the  size  of  the  gland  have  much  effect.  The  giand-lolx's  may  be 
less  in  amount  than  the  fat  of  the  organ,  though  usually  a  well-developed  breast 
and  nipple  presage  a  good  milk  supply. 

Fourth,  nutrition  of  the  patient,  to  a  certain  degree — a  woman  in  good 
health  is  more  likely  to  give  sufficient  milk  than  a  sickly  mother,  but,  occasionally; 
one  sees  a  tuberculous  mother  with  a  fat,  healthy  l)al)y. 

Fifth,  age  of  the  patient.  This  has  very  little  influence,  though,  Ijefore  the 
age  of  eighteen  and  after  forty,  the  milk  is  likely  to  suffer  l)oth  in  (juality  and 
in  quantity. 

Sixth,  toward  the  entl  of  lactation  the  milk  gets  poor  in  quality  and  less  in 
quantity,  though  there  are  exceptions. 

Seventh,  the  milk  of  the  two  breasts  varies  in  quantity  and  quality,  and  from 
day  to  day,  and  at  different  times  of  the  day,  and  during  a  single  nursing.  The 
proteids,  fat,  and  sugar  increase  in  amount  with  the  emptying  of  the  breasts. 

Eighth,  hunger  decreases  the  amount  of  the  milk;  fat,  casein,  and  sugar 
decrease,  while  the  amount  of  albumin  increases.  These  facts  were  found  by 
Decaisne  during  the  siege  of  Paris. 

Ninth,  emotions  may  alter  quantity  and  ciuality — it  is  said  that  extreme 
emotional  shock  may  so  alter  the  milk  that  it  will  give  the  child  colic,  diarrhea,  or 
even  convulsions;  that  nervous  shock  may  produce  agalactia  is  well  known. 

Tenth,  menstruation  has  a  distinct  effect  on  the  nursing  child — it  may  have 
colic,  or  cry  agreatdeal,  and  may  pass  green  stools,  vomit,  or  have  diarrhea;  though, 
chemically,  one  can  find  no  alteration  in  the  milk.  The  changes  last  only  a  short 
time. 

Eleventh,  yregnancy — the  milk  gradually  dries  up,  after  becoming  more 
watery.  Very  often  the  nursing  mother  observes  a  change  in  the  nutrition  of  the 
infant  and  ascribes  the  same  to  the  advent  of  a  new^  pregnancy. 

Twelfth,  drugs  often  reappear  in  the  milk.  This  has  been  known  since 
Hippocrates,  in  connection  with  cathartics.  One  may,  in  order  to  purge  the  infant, 
give  the  mother  the  cathartic.  Alcohol  is  said  also  to  pass  over,  and  cases  are  cited 
w^here  the  baby  got  drunk.  Opium  has  caused  narcosis  of  forty-three  hours  in  the 
baby.  Iron,  arsenic,  iodin,  lead,  and  mercury  are  well  know'n  to  pass  over.  Sal- 
varsan  may  thus  be  used  for  the  treatment  of  mother  and  babe. 

Briegcr  has  shown  that  immunizing  doses  of  tetanus  antitoxin  pass  over  to  the 
infant.  The  wTiter  allowed  a  woman  with  diphtheria,  wiio  had  large  doses  of  anti- 
toxin, to  nurse  her  infant.  The  child  did  not  take  diphtheria,  thougli  Hofbauer 
claims  that  the  diphtheria  antitoxin  is  not  transmitted  to  the  child.  Vaccinia  is  not 
believed  to  pass  over.  The  only  drug  wiiich  has  any  effect  on  the  amouiit  of  the 
milk  secreted  is  iodid  of  potash.     It  limits  the  output. 

Thirteenth,  disease  has  an  impoi'tant  effect  on  the  milk.  Diarrheas  cause  a 
diminution;  in  cholera,  sometimes  complete  absence.  In  sepsis  the  milk  some- 
times dries  up,  which  is  a  bad  omen.  Bacteria  can  pass  into  the  milk  in  disease 
(Kehrer).  Tuberculosis,  anthrax,  may  pass  over  without  any  demonstrable  change 
in  the  gland.     In  mastitis  the  milk  may  contain  cocci  and  pus. 

Fourteenth,  irritation  of  the  nipples  causes  an  increase  of  the  secretion.  This 
is  demonstrated  clinically  in  many  W'ays — e.  g.,  by  placing  tiie  baby  to  the  breast

early,  tlio  milk  oomos  oarlior,  and  hy  iisins  the  l)r('ast-pump  too  much  to  "ri'lieve" 
the  breasts,  more  milk  is  jirodueed.  It  is  possible  to  start  lactation  in  a  non- 
puerperal woman,  even  in  young  girls,  by  properly  stimulating  the  brea.sts.  Mas- 
sage of  the  breasts  and  cold  baths  increase  the  milk  supply. 

Fifteenth,  certain  fcjods  are  said  to  increase  tiie  secretion,  as  tomatoes, 
oysters,  anil  gruels.  My  experience  with  them  is  negative.  Li(|uiils  increas*-  tlie 
amount  of  milk,  and  a  rich  supply  of  jjroteids  in  the  diet  .seems  to  augment  the  fat 
content.  Overfeeding,  however,  in  the  author's  experience,  only  occasionally 
improves  the  nursing,  and  then,  temporarily.  Later,  the  mother  puts  on  fat  and 
the  breasts  dry  up.  If  there  is  no  gland  tissue  in  the  breast,  no  aUKJunt  of  stinujla- 
tioii  will  cause  it  to  secrete. 

Certain  foods  are  .said  to  alter  the  milk  to  the  disturbance  of  the  child — e.  y., 
strawberries,  tomatoes,  beans,  and  acid  fruits.  It  does  .seem  that  idiosyncracies, 
pos.se.sse(l  by  the  mother,  also  Ix-come  evident  in  her  offspring. 

Sixteenth,  multiparie  usually  have  more  milk  than  primipara^,  and  women, 
after  normal  labor,  are  less  likely  to  have  disturbed  lactation  than  tho.se  who  have 
had  difficult,  operative  deliveries,  especially  if  attended  with  great  loss  of  blood. 

Seventeenth,  the  amount  of  milk  varies  with  the  demand.  (Ordinarily  the 
breasts  give  (iOO  to  <S()()  gm.  per  tlay.  depending  on  the  needs  of  the  nursling,  but 
Budin  has  recordetl  cashes  where  a  wet -nurse  produced  2oUU  to  2800  gm.  of  milk 
per  ilay,  for  a  long  period,  without  injury. 

If  the  nursing  is  interruptetl  from  any  cause,  it  may  be  resumed,  providing  the 
interval  is  not  too  long.  The  author  has  seen  the  secretion  of  milk  return  after  an 
absence  of  five  weeks,  and  cases  are  recorded  of  its  return  after  months. 

Lactation  has  a  not  unimportant  bearing  on  the  general  condition  of  the  woman. 
A  certain  amount  of  blood  and  fat  must  be  eliminated  after  pregnancy.  Part  of 
these  go  in  the  lochia,  jwrt  in  the  excreta,  and  part  in  the  milk.  If  the  la.st  is  not 
excreted,  the  other  organs  must  remove  the  excess  and,  according  to  Kehrer,  con- 
gestion of  the  genitalia  is  likely  to  occur.  It  is  a  fact  that,  when  the  jjatient  does 
not  nurse,  the  lochia  are  increa.sed,  anil  the  involution  of  the  uterus  is  delayed,  but 
this  is  generally  explained  by  the  absence  of  the  reflex  irritation  which  nursing 
causes  on  the  uterus.  The  act  of  nursing  causes  uterine  contractions  in  the  early 
puerperium,  which  are  a  prominent  symptom,  as  "after-jjains,  "  and  these  favor  the 
rapid  involution  of  the  uterus.  Positiv^e  observations  are  not  on  record,  but,  in 
general,  it  may  be  .said  that  a  woman  recovers  better  from  her  labor  if  she  nurses 
her  offspring.  Lehman  finds  slight  statistical  indications  that  the  neglect  of  lacta- 
tion favors  the  development  of  carcinoma  of  the  breast.

CHAPTER  XV 

GENERAL  CHANGES  IN  THE  PUERPERIUM 

ItIs  surprising  how  little  the  general  condition  of  the  woman  is  affected  by  such 
a  severe  storm  as  is  even  a  normal  labor.  In  the  absence  of  infection,  most 
women  feel  quite  well  during  the  puerperal  period.  The  soreness  of  the  genitalia, 
due  to  the  vulvar  wounds,  disappears  in  a  few  days,  the  soreness  of  the  muscles 
like^^'ise,  and,  even  after  a  few  hours,  the  patient  feels  rested  from  the  severe  exer- 
cise of  delivery.  Women  unused  to  exertion  recover  less  quickly  from  the  strain. 
After  a  difficult  operative  delivery,  however,  and  after  a  severe  hemorrhage,  w^e 
find  the  symptoms  that  would  naturally  go  with  such  conditions,  and  the  occurrence 
of  surgical  shock  must  also  be  mentioned.  A  multijxira  is  likely  to  be  annoyed  by 
after-pains.  These  are  painful  uterine  contractions  which  recur  more  or  less  regu- 
larly for  one,  two,  three,  or  even  six  days.  The  contractions  occur  especially  when 
the  child  nurses,  a  refiex  going  to  the  uterus  from  the  breasts,  or  when  the  uterus  is 
massaged,  but  especially  when  pieces  of  membrane,  of  placenta,  or  blood-clots  have 
been  left  in  the  uterus.  Women  who  have  had  endometritis,  metritis,  frequent 
abortion,  rapidly  successive  labors,  overcUstention  of  the  uterus  by  twins,  poly- 
hydramnion,  or  very  quick  labors,  are  likely  to  suffer  more  with  after-pains. 
Primiparae,  because  the  uterus  remains  in  a  state  of  good  tonus,  are  less  likely  to 
suffer  w^ith  them.  If  these  painful  contractions  reappear  after  they  have  once 
ceased,  it  is  indicative  of  something  wrong  in  the  uterus — either  infection  or 
retained  secundines,  a  fibroid,  etc. 

The  Nervous  System. — Puerperse  are  more  sensitive  to  irritations,  a  fact  which 
was  known  to  the  Romans,  and  they  placed  a  sign  before  her  door,  so  that  she  was 
not  disturbed — even  by  the  tax  collector.  The  reflex  excitability  is  increased. 
Recent  investigations  of  the  knee-jerk  show  that  in  pregnancy  this  reflex  is  more 
active  than  usual,  that  it  is  most  active  in  labor  at  the  height  of  a  pain,  while 
during  the  puerperium  the  excitability  gradually  passes  away.  Puerperse  hear 
more  acutely  and  are  more  sensitive  to  light  and  odors.  Though  many  writers,  and 
most  nurses,  believe  that  a  nervous  shock  can  cause  fever,  the  author  has  never 
observed  an  unequivocal  case  where  such  a  severe  emotional  storm  has  raised  the 
patient's  temperature.     (See  chapter  on  Puerperal  Infection.) 

The  Temperature. — Variations  in  the  temperature  of  puerperal  women  form  a 
most  important  index  of  her  health,  and,  together  with  the  pulse,  give  us  reliable 
information.  Although  attended  by  severe  muscular  exertion,  labor  does  not,  as  a 
rule,  raise  the  temperature  more  than  one-half  degree.  If  the  labor  terminates  in 
the  afternoon,  the  usual  rise,  at  this  time,  may  be  exaggerated;  but  in  normal  cases, 
a  parturient's  temperature  should  not  go  above  100.2°  F.  Even  this  makes  one 
suspicious  of  infection.  The  so-called  "physiologic  chill"  is,  in  the  author's 
opinion,  the  result  of  the  flooding  of  the  system  with  toxins  or  bacteria  from  the 
puerperal  wounds,  or  possibly  alien  proteids,  as  was  told  on  p.  127.  The  temper- 
ature may  rise  one-half  degree  after  labor,  but  falls  to  the  normal  within  twelve 
hours,  and  then  shows  the  physiologic  diurnal  variations,  but  these  do  not  exceed 
1°  F.  Many  authorities  admit  that  a  puerperal  woman  may  normally  have  fever. 
Fehling  considers  every  rise  above  101.1°  F.  jiathoiogic;  Winckel  places  the  limit 
at  100.7°  F.;  Boxall,  of  London,  at  100°  F.;  ^^■illialns'at  100.4°  F.  It  is,  to  a  great 
extent,  arbitrary.     My  own  experience  is  that,  if  the  temperature  rises  above 

218 


GENERAL    CHANGES    IX    THE    I'lEIU'EUIl  M  219 

90.5°  F.,  there  is  almost  always  sonic  cause  for  it — usually,  a  mild  infection.  This, 
then, — 09.0°  V., — is  given  as  the  limit  for  a  puerperium  which  may  lie  calletl  nor- 
mal, but  it  is  not  meant  that  a  woman  showing  a  slightly  higher  fever  must  be 
very  ill  or  in  danger.  In  such  cases  one  is  warned  to  more  careful  asepsis  in  the 
daily  technic  of  delivery  and  a  painstaking  study  into  tiie  cause  of  the  elevation 
in  each  in<lividual  ra^^r. 

Primipane  show  higiicr  temperatures  and  greater  fluctuations  than  nmlti- 
para?,  because  in  them  there  arc  more  wounds  and  greater  possibilities  for  the  al>- 
sorption  of  toxins.  After  hard  ojx'rative  deliveries,  after  many  internal  examina- 
tions, the  temperature  is  often  higher  and  more  lal)ile. 

There  is  no  such  thing  as  "milk  fever"!  Formerly,  in  the  non-ant i.septic  era, 
almost  every  puerpera  had  fever  on  the  third  day.  Since  at  this  time  the  breasts 
become  large  and  hard,  the  fever  was  ascribed  to  the  violent  coming  of  the  milk, 
and  the  real  cause,  tiie  infection  of  the  genitalia,  was  overhjcjked.  With  the  advent 
of  antisepsis  there  has  been  a  great  decrease  in  this  so-called  "milk  fever,''  and  large 
numbers  of  the  best  authorities  deny  its  existence.  Jaggard  .said  he  had  never 
seen  a  case  where  there  was  fever  and  no  other  cause  to  be  found  than  simply  the 
coming  of  the  milk.  I  have  .seen  primipariB  with  the  brea.sts  standing  out  hard  and 
firm,  the  axillary  lolx*  of  the  gland  so  swollen  that  the  patient  had  to  keep  tlie  arms 
from  the  sides,  and  yet  the  temperature  was  98.6°  F.  Infection  of  the  breasts  is 
another  thing.  "Milk  fever"  is  a  misnomer  that  should  be  abolished  from  ob- 
.stetrics.  It  too  often  forms  the  cover  for  severe  puerperal  infections,  and  many 
women  have  lost  their  lives  because  of  neglect  of  the  real  disease. 

The  reason  usually  given  that  the  pueri)eral  woman  should  have  some  fever  is 
this:  The  jjrotlucts  of  the  regressive  metamorj)hosis  of  the  uterus  and  all  the  geni- 
talia being  ab-sorbed,  must  be  oxidized.  This  increased  oxidation  causes  the  in- 
crea.se  in  the  body  heat.  But  nature,  l)y  increasing  the  ])erspiration  and  other 
excretions,  keeps  the  temperature  nearly  normal.  The  slight  rise  of  temjx'rature 
right  after  delivery  is  prol)al)ly  a  mild  infection.  The  older  writers  called  it  fibrin 
ferment  fever. 

The  temperature  of  the  puerperal  woman  is  subject  to  fluctuations  on  slighter 
causes  as  compared  with  the  non-puerperal  woman. 

Con.stijxition  is  said  to  give  rise  to  temperature,  wiiich  goes  down  when  the 
bowels  are  emptied.  This  fever  is  probably  due  to  obstruction  to  the  flow  of  lochia, 
which  is  overcome  when  the  rectum  is  emptietl,  but  may  be  due  to  ai).sorption  from 
the  intestine.  It  is  safest,  as  soon  as  your  puerperse  have  fever,  to  think  of  infection 
first.  A  full  ])ladder  may  act  similarly,  Init  it  is  ^\^se  to  bear  in  mind  the  frequency 
of  ureteropyelitis  in  i)ueri)erio.  While  fever  may  arise  from  the  l)owels.  as  from 
enteritis,  I  have  never  been  fully  convinced  that  constipation  itself  will  cau."<e  it. 

The  PHilse. — In  the  second  stage  of  labor  the  pulse  is  strong,  rapid,  perhajis 
irregular;  l)ut  during  the  third  .stage  it  calms  down  and  is  normal  throughout  this 
time,  unless  there  is  a  .severe  hemorrhage,  when  it  becomes  small  and  fast.  Im- 
mediately after  labor  the  pul.se  is  soft ;  soon  it  has  a  high  tension,  especially  in  nud- 
tipariB,  but  the  l)lood-pre.ssure  then  sinks  slowly  to  below  normal  or  about  normal. 

A  very  high  tension  slow  pulse  must  be  regarded  as  a  warning  of  eclamjisia. 
In  general,  the  i)ulse  during  the  puerperium  runs  from  tiS  to  80,  which  is  al)out 
normal,  though  higher  rates  are  sometimes  found,  even  in  healthy  women. 

A  peculiar  jihenomenon  is  sometimes  ob.scrved  in  healthy  puerpera\  The  pulse- 
rate  may  l)e  as  low  as  40  a  minute,  and  some  observers  have  found  30,  l)ut 
this  is  very  rare.  It  occurs  after  labors  at  term  more  than  after  early  al>ortions; 
in  multipane  more  often  than  in  primiparic;  in  phlegmatic  women  oftener  than  the 
neurotic;  in  lean  oftener  than  fat  women.  The  author  has  found  a  pulse  of  below 
t>9  in  only  10  per  cent,  of  his  cases.  Other  authors  give  Hi. 2  j)er  cent.  (Hemeys) 
and  63  per  cent.  (Olshausen).     The  cause  is  not  known.     Lynch  gives  the  litera- 


220  THE    PHYSIOLOGY    OF   THE   PUERPERIUM 

ture.  There  are  many  theories,  of  which  the  most  phiusible  are:  Fehling's — the 
sudden  diminution  of  the  intra-abdominal  tension  irritates  the  vagus  refiexly; 
Schroder's — the  heart,  which  hypertrophies  during  pregnancy,  now  need  not  W'ork 
so  hard;  Olshausen's — the  fat,  which  is  absorbed  from  the  uterus,  slows  the  heart. 
Further,  the  horizontal  position,  the  quiet  of  the  patient,  the  less  amount  of  food, 
the  great  excretion  of  liquid  in  milk,  lochia,  sweat,  etc.,  may  conduce  to  the  slow 
pulse.  It  is  of  great  prognostic  significance.  A  slow  pulse  indicates  that  every- 
thing is  going  along  nicely. 

A  very  rapid  pulse  in  the  pu(^rperium,  in  the  absence  of  fever,  points  to  hem- 
orrhage, recover}'  from  severe  hemorrhage,  or  some  heart  disease.  Not  seldom  a 
rapid  pulse  draws  attention  to  the  condition  of  the  heart,  but  one  must  be  careful 
in  the  diagnosis  of  heart  disease  during  pregnancy  and  the  puerperium,  because 
murmurs  are  common  (70  per  cent.),  and  a  displaced  heart  simulates  liAioertrophy. 
The  pulse  is  more  labile  during  the  puerperium  than  the  temperature.  It  warns 
much  quicker  of  the  advent  of  sepsis  or  other  puerperal  complication,  but  is  less 
reliable.  It  fluctuates  with  the  after-pains  and  with  any  little  excitement — as 
visitors  and  nursing  the  baljy.  The  usual  relation  between  temperature  and  pulse 
obtains  here  as  elsewhere. 

The  Blood. — There  is  a  decrease  in  the  amount  of  blood  (Sengel),  which  had 
increased  during  pregnancy,  an  evidence  of  the  loss  during  labor  and  especially  if 
delivery  was  accompanied  by  much  hemorrhage.  The  hemoglobin  is  dispropor- 
tionately reduced.  The  lochia,  sweat,  and  other  excreta  tend  to  impoverish  the 
blood  in  the  first  week,  so  that  in  the  first  daj'S  after  lal^or  there  may  be  a  decrease 
of  both  reds  and  whites.  During  labor,  the  leukocyte  count  varies  from  9000  to 
34,000,  w^th  an  average  of  18,000,  the  increase  being  in  the  polynuclear  neutrophiles. 
The  eosinophiles  are  often  absent.  The  reds  vary  from  4,000,000  to  5,500,000. 
After  labor  the  leukoc\'tosis  rapidly  disappears,  even  Avithin  twenty-four  hours,  but 
usually  it  reciuires  several  days  for  the  count  to  come  down  to  the  normal  limits — 
7500  to  15,000,  which  is  somewhat  higher  than  in  the  non-puerperal  state.  The 
normal  proportion  of  the  various  whites  is: 

Neutrophiles GO  to  75  per  cent. 

Lymphocytes ■.  .  .  .  25  per  cent. 

Eosinophiles 2  to    5  per  cent. 

These  proportions  vary  from  day  to  day.  About  the  fifth  day  one  occasionally 
observes  a  slight  eosinophilia,  which  is  more  marked  after  the  birth  of  twins,  of 
macerated  fetuses,  and  in  gonorrheal  cases.  Infection  alters  the  blood-picture. 
(See  p.  852.) 

The  respiration  is  not  much  altered  in  frequency,  but  responds  more  readily 
to  disturbances.  The  chest  being  free,  expands  more  easily  than  during  preg- 
nancy, the  type  of  l)reathing  being  costal  and  diaphragmatic.  The  vital  capacity 
is  increased  after  the  third  day.  On  percussion  one  finds  a  deeper  resonance.  The 
heart  dulness  sinks  a  little. 

The  Skin. — All  the  functions  of  the  skin  are  more  active,  the  sweat-glands 
particularly.  After  labor,  when  the  patient  is  well  covered  up,  she  breaks  out  with 
a  full,  warm  sweat,  but  this  is  rarely  so  profuse  as  to  require  a  change  of  bed-lin(»n. 
It  is  favored  by  the  warm  covers  and  the  administration  of  warm  drinks.  That 
there  is  a  sweating  peculiar  to  puerpera  is  not  true,  but  the  perspiration  has  a 
peculiar  odor,  which  varies  in  health  and  disease.  During  the  lying-in  there  is  a 
tendency  to  perspiration,  especially  in  sleep,  but  it  is  less  in  the  latter  days,  probably 
because  of  the  esta})lishment  of  the  milk  secretion  and  the  free  lochia. 

The  laity  have  great  fear  that  the  patient  takes  cold  at  this  time.  This  is  the 
outgrowth  of  the  old  belief  that  puerperal  fever  comes  from  catching  cold,  a  view

still  lu'ld  lunoiiK  the  midwivos,  and  in  their  jjracticc  it  is  not  unusual  to  find  the 
windows  dosed  and  tiic  patient  covered  with  heavy  blankets,  even  in  summer. 

Ahlfeld  says  that  t  here  is  some  connection  between  the  appearance  of  the  sweat 
niid  the  coiit  i-:icli()ii  and  ret  lact ion  of  the  uterus  after  labor. 

The  Kidneys  and  Urinary  Apparatus.—  Uelieved  suddenly  fnjm  the  increa.sed 
intra-abdominal  pres.sure  by  the  delivery  of  the  chikl,  the  kidneys  bec(tme  active. 
In  the  third  stage  it  is  not  rare  to  find  the  bladtler  full  and  even  overfilled,  making 
an  obstacle  to  the  delivery  of  the  placenta. 

In  the  first  twelve  hours  there  is  usually  retention  of  urine,  which  sometimes 
may  be  enormous  and  cause  ischuria  i)aradoxa.  This  is  due  to  the  laek  of  elasticity 
of  the  bladder,  inability  to  urinate  in  the  horizontal  position,  the  swelling  of  the 
vulva  and  urethra,  kinking  of  the  urethra  (Olshausen),  reflex  spasm  of  the  sphincter 
from  stitches  in  the  perineum,  and  injury  to  the  bladder  trigonum  and  urethral 
orifice,  with  edema.  Still,  ciuite  a  few  puerpcra^  pass  urine  spontaneously.  In 
many  cases  it  is  necessary  to  use  the  catheter.  As  a  rule,  patients  pass  urine  three 
times  daily,  much  less  often  than  in  the  later  months  of  pregnancy. 

(\vstosco])ic  (examination  of  the  bladder  after  labor  shows  the  effect  of  the  bruis- 
ing sustained  during  the  expulsion  (jf  the  child.  The  trigonum  and  urethral  orifice 
are  edematous  and  strewn  with  minute  blood  extravasations.  The  epithelium 
desciuamates  and  lies  on  the  mucous  membrane  as  a  grayish  film.  After  prolonged 
deliveries  and  hard  ojierations,  the  bladder-wall  is  much  crushed,  and  in  the  cysto- 
scope  we  see  the  above  effects  much  more  marked  (Fig.  259).  The  ureteral  orifices 
are  not  easily  found,  but  the  ureters  are  very  easily  i)alpable,  being  usually  somewhat 
enlarged.  The  laceration  of  the  urogenital  septum,  and  of  the  connective  tissue 
around  the  base  of  the  bladder,  allows  the  anterior  wall  of  the  vagina  to  prolapse, 
carrying  the  urethra  and  neck  of  the  bladder  with  it. 

The  urine  collected  just  after  delivery  fn^iuently  contains  a  little  albumin, 
white  blood-corpuscles,  a  few  reds  and  scattered  hyaline  casts.  In  twelve  hours 
the  latter  disappear.  The  amount  of  urine  for  the  first  eight  days  is  300  to  400 
c.c.  more  than  that  of  the  non-pregnant  woman,  but  is  not  much  more  than 
that  of  the  i)regnant  woman  in  the  latter  months  (Kehrer). 

The  s|iecific  gravity  varies  from  1010  to  102"),  according  to  the  amount  of 
urine.  The  urea  varies  from  2.0  per  cent,  to  1.6  per  cent.,  being  highest  on  the  third 
day, the  excess  being  ascribableto  the  increased  metabolism  of  lactation — the  change 
of  the  albuminoids  into  fat.  It  is,  therefore,  less  in  women  who  do  not  nurse.  The 
jjroportion  of  salts,  ph()S])hates,  and  sulphates  does  not  vary  much  from  the  normal 
— l)erhaps  the  salt  outi>ut  is  increased. 

Milk-sugar  occurs  in  SO  per  cent,  of  pueri)eral  urines  (von  Xoorden).  It  is  de- 
rived from  the  breasts.  Blot  first  called  attention  to  this  physiologic  lactosuria.  It 
is  greatest  during  the  establishmentof  lactation, absent  during  its  proper  functionat- 
ing, and  appears  again  during  the  weaning  ])ro('ess.  The  average  is  0.2  per  cent., 
but  this  may  be  increased  to  1  ixTcent.  by  feeding  with  all)umin()ids  and  ctirbohy- 
drates. 

Pejitone  has  been  found  in  the  urine  by  Fischel  from  the  .second  to  the  tenth 
day,  and  is  ascribed  to  the  al):<orption  of  ]iroducts  of  albuminoid  degeneration 
going  on  in  the  uterus.  Albuminuria  occurs  in  40  \)vr  cent,  of  the  cases  of  lal)or,  l>ut 
this  di.sa])pears  before  the  third  day.  If  it  does  not,  or  if  albumin  reappears,  its 
cause  must  be  sought  out.  Nephritis,  pyelitis,  ureteritis,  cystitis,  post- anesthetic 
effects,  eclampsia,  and  sepsis  must  be  considereil.  To  avoid  confusion  from  the 
admixture  of  lochia,  only  catheterized  s])ecimens  may  l)e  used. 

Lactic  acid,  acetone,  pejjsin.  and  toxins  have  been  found  in  the  urine  of  puer- 
perie. 

The  Intestinal  Tract. — The  puerperie  are  very  thirsty  and  drink  much,  but 
the  appetite  usually  is  poor  for  the  first  three  days.     Loss  of  fluids  during  lal)or,  and 


222  THE    PHYSIOLOGY    OF   THE    PUERPERIUM 

in  the  lochia,  urine,  and  sweat,  exphiins  the  thirst.  After  labor,  the  belly  is  flat, 
even  slightly  concave,  but  soon  a  moderate  tympany  appears.  In  thin  women  the 
uterine  tumor,  the  large  and  small  intestines,  with  their  peristalsis,  the  liver,  spleen, 
and  kidneys  are  very  easily  palpable,  and  one  may  use  the  opportunity  for  investiga- 
tion of  these  organs. 

A  moderate  tympany  is  normal  in  the  puerperium;  it  is  due  to  slight  intestinal 
paresis,  and  accompanies  the  usual  constipation.  Rarely  do  the  bowels  move  spon- 
taneously in  the  first  few  days  of  the  puerperium.  The  causes  of  the  obstipation 
are:  The  bowels  usually  have  lieen  emptied  l)y  cathartics  before  labor;  the  woman 
eats  little,  and  the  excretion  of  fluids  is  so  rapid  that  the  intestinal  contents  dry 
up;  the  abdominal  and  perineal  muscles,  because  of  overstretching,  cannot  do  their 
work;  a  patient  usually  has  difficult}'  in  defecating  while  lying  on  the  back;  and 
the  pain  in  the  parts  may  inhibit  the  action. 

Older  writers  believed  that  constipation  could  cause  puerperal  infection.  That 
constipation  alone  may  cause  fever  I  have  some  doubts,  but  in  these  cases  the  fever 
would  come  from  the  intestinal  canal,  not  from  the  genitalia.  A  brisk  purge  may  be 
followed  by  a  fall  of  temperature  in  a  case  of  real  puerperal  infection,  and  one  may 
be  misguided  into  ascribing  the  fever  to  the  intestines,  when,  in  reality,  the  purge 
simply  stirred  up  the  pelvic  circulation,  emptied  the  lower  bowel,  provided  good 
drainage  for  the  lochia,  and  perhaps  increased  the  local  and  general  leukocytosis  so 
that  the  infection  was  taken  care  of.  The  author  does  not  believe  that  constipa- 
tion or  errors  of  diet  (another  popular  fancy  and  fallacy)  can  cause  puerperal 
infection. 

The  weight  of  the  patient  undergoes  marked  changes  in  the  first  months 
after  labor.  According  to  Gassner,  the  average  weight  of  238  women,  on  the 
day  after  labor,  was  124  pounds.  In  the  first  two  weeks  they  lost  about  9 
pounds,  or  8  per  cent,  of  their  weight — Baumm,  6.58  per  cent.  The  loss  is  greater 
in  multiparse,  greater  in  large  women,  and  after  full  term  than  premature  lal^or, 
also  greater  after  twins.  This  loss  of  weight  is  due  to  the  moderate  amount  of 
food  taken  and  the  great  amount  of  excreta — the  sweat,  the  urine,  but  especially 
the  lochia  and  the  milk.  The  women  look  thin,  pale,  and  washed  out  after  getting 
up,  and  need  a  tonic  diet.  The  weight  is  regained  in  four  to  six  weeks,  many  women 
putting  on  excessive  fat.  Nowadays,  since  we  do  not  starve  the  women  so  much  in 
the  puerperium,  these  losses  are  not  so  marked,  but  the  custom  of  feeding  puer- 
perse  very  lightly  still  exists  in  many  places.

SECTION  IV 

THE  HYGIENE  AND  CONDUCT  OF  PREGNANCY  AND  LABOR 


(•ii.\P'n;i{  x\i 

THE  CHILD 

Few  women,  in  roaring  a  daughter,  consider  the  possil)ility  of  her  future  preg- 
nancy and  labor,  and  make  the  attempt  to  prepare  her  for  their  successful  accom- 
plishment. Many  women  believe  that  while  the  child  is  in  utero  it  can  be  influenced 
by  the  mental  ()ccu])ati()n  of  the  mother;  thus,  for  exam])le,  if  she  desires  a  nmsical 
child,  she  should  study  music  assiduously  during  i)regnancy.  Then,  too,  most 
intelligent  mothers  try  to  live  a  hygienic  life  during  gestation  and  do  those  things 
which  seem  to  promise  normal  healthy  offspring.  Some  few  intelligent  parents 
try  to  arrange  the  most  auspicious  circumstances  at  the  time  of  jirocreation  of  their 
children,  but,  beyond  such  desultory  efforts,  very  little  attention  is  ])aid  to  the 
science  of  Eugenics.  Indeed,  to  l)e  well  born  one  must  go  back  many  generations, 
but  it  is  certainly  tlemanded  that  a  beginning  should  be  made  at  once,  to  provide  for 
posterity.  Only  in  the  human  animal  are  the  laws  of  successful  procreation  defied. 
The  influences  of  heredity,  of  disease,  of  character,  of  environment,  are  all  set  at 
naught,  and  the  i)ropagation  of  the  species  left  to  chance,  to  lust,  or  to  convenience. 

Incontestable  evidence  exists  to  prove  that  the  children  of  alcoholics  are  often 
weak,  puny,  imbecile,  or  epileptic.  Insanity,  the  tendency  to  drug  addictions, 
venereal  disease,  hemophilia,  nephritis,  aiul  other  affections,  or  a  predisj^osition  to 
the  same,  are  undoubtedly  transmitted,  and  their  effects  maybe  discovered  even  in 
the  third  generation.  As  far  as  the  obstetrician  is  concerned,  these  facts  carry 
weight  as  matter  to  be  included  in  his  history-taking  in  individual  cases,  for  they 
will  shed  light  on  many  complications  occurring  in  the  course  of  pregnancy  and 
parturition,  and  indicate  what  measures  to  pursue^  in  preventing  and  treating  such 
complications  (Ballantyne).  After  a  girl  is  l)orn,  however,  nuich  may  be  done  to 
correct  an  evil  ancestry  and  to  prevent  diseases  which  would  affect  her  procreative 
ability.  A  well-developed  child  requires  at  least  thirty-six  weeks  of  uterogestation. 
Prematurely  born  girls  not  seldom  show  skeletal  and  genital  infantilism,  the  latter 
causing  dysuKMiorrhea  and  sterility  and  neuroses,  the  former,  contracted  peKns 
with  dystocia  (abnormal  labor).  Another  cause  of  infantilism,  not  generally 
recognized,  is  intestinal  disturbances,  especially  infection,  during  the  first  two  years 
of  life.  Atrophy  of  the  intestinal  glands  leads  to  permanent  hyjiojila-^^tic  changes  in 
the  whole  system.  Since  bottle-fed  children  are  most  likely  to  suffer  from  such 
infections,  th(>  obst<>trician  will,  all  the  more,  seek  to  enforce  breast -feetling,  with  the 
future  of  the  baby  in  view. 

The  new-born  child  is  very  easily  infected,  and  vulvitis  and  vaginitis  not  seldom 
occur.  That  such  may  lead  to  subsecjuent  jK'lvic  disea.>^e  is  beyontl  question. 
Mastitis  in  the  new-l)orn  girl  may  result  in  comjilete  destruction  of  the  mammary 
gland,  with  resulting  agalactia  in  the  puerjierium.  Rachitis  in  very  early  life  is 
not  uncommon,  anil  it  may  distort  the  pelvic  bones.  While  the  resulting  deformity 
only  in  severe  cases  produces  an  absolute  disproportion  between  the  child  and  the 

223 


224  THE  HYGIENE  AND  CONDUCT  OF  PREGNANCY 

pelvis,  milder  degrees  of  pelvic  distortion  cause  abnormalities  in  the  mechanism  of 
labor  which  not  seldom  cost  the  life  of  the  mother  or  the  babe,  and  often  leave 
serious  injury  to  both. 

The  acute  infectious  diseases — scarlatina,  diphtheria,  anterior  poliomyelitis, 
etc. — not  seldom  leave  permanent  traces  on  the  child,  as  nephritis,  hepatitis,  and, 
in  the  last  instance,  paralysis,  with  shortening  of  tlie  leg  and  consequent  distortion 
of  the  pelvis. 

These  few  examples  are  given  to  intlicate  the  scope  of  prophylaxis  in  early  life, 
from  an  ol)stetric  point  of  view,  and  much  can  b(^  done  l)y  a  wise  hygiene  to  preserve 
the  growing  girl  from  the  evils  of  disease,  environment,  and  heredity. 

PUBERTY 

At  this  time,  when  mighty  changes  are  going  on  in  the  internal  and  external 
genitalia,  the  foundation  of  permanent  disease  may  be  laid.  It  is  beyond  question 
that  the  crowding  of  the  child's  mind  with  studies  and  accomplishments,  the  pre- 
mature social  duties,  together  with  inappropriate  reading  and  company,  and  a  lack 
of  outdoor  exercise  and  sports,  tend  to  develop  the  mind  at  the  expense  of  the  body, 
particularly  the  sexual  organs,  which  require  so  much  of  the  girl's  vitality  at  this 
period.  Dysmenorrhea,  hypoplasia  of  tlie  uterus,  later,  chlorosis,  are  some  of 
the  results  of  these  evils.  Early  womanhood  also  requires  proper  hygienic  conduct 
if  one  wishes  to  develop  a  healthy  nervous  system  and  a  normal  reproductive  func- 
tion. Of  transcendent  importance  is  the  proper  instruction  of  the  growing  girl  in 
the  principles  of  sex  and  reproduction.  Only  in  this  way  will  it  be  possible  to  save 
the  girl  from  ignorantly  performing  secret  practices,  e.  g.,  masturbation,  to  restrict 
the  spread  of  venereal  disease,  the  number  of  illegitimate  births  and  criminal  abor- 
tions. It  is  impossible  to  go  deeper  into  this  important  subject  here,  but  that  the 
obstetrician  is  concerned  in  this  matter  goes  without  saying,  and  l^y  wise  counsel, 
at  this  particular  time,  he  may  save  the  girl  from  permanent  invalidism,  even  from 
death  in  childbirth  (Surbled). 

MENSTRUATION 

Unfortunately,  most  women  cannot  take  sufficient  care  of  themselves  during 
this  monthly  illness,  but  many  who  could  do  so  are  very  careless  with  themselves. 
Examples  of  great  neglect  are  common.  Immoderate  dancing,  exposure  to  cold 
with  thin  clothes,  sexual  excitement,  hot  baths  taken  to  bring  on  the  period,  all 
cause  catarrhal  conditions  of  the  uterus,  which  predispose  to  abortion,  adherent 
placenta,  and  postpartum  hemorrhage. 

THE  HUSBAND 

The  part  played  by  the  husband  in  obstetric  complications  has  never  been 
properly  noticed.  If  he  is  unusually  large  and  heavy  boned,  he  may  procreate  chil- 
dren too  large  for  his  wife  to  bear.  Venereal  disease  communicated  to  the  wife  is  so 
common  that  obstetricians  reckon  with  it  all  the  time.  Under  this  heading  may  be 
mentioned  the  local  inflammations  of  the  female  urinary  tract,  cystitis,  ureteritis, 
pyelitis,  surgical  kidney;  vulvitis,  endometritis,  with  adherent  placenta,  postpartum 
hemorrhage,  subinvolution,  etc.;  pyosalpinx  with  gonorrheal  and  streptococcic 
(often  fatal)  peritonitis;  syphilitic  macerated  fetus,  with  maternal  hemophilic  ten- 
dencies; gonorrheal  ophthalmia  of  the  new-born,  and  other  fetal  disease.  These  need 
only  to  be  indicated  to  show  that  the  husband  is  directly  concerned  in  our  discussion. 

Too  frequent  intercourse  during  ]iregnancy  often  causes  abortion,  premature 
labor,  and  even  abruptio  placenta?.  One  inii:)ortant  fact,  and  it  will  be  again  re- 
ferred to,  is  that  coitus  in  the  latter  weeks  of  pregnancy  may  cause  infection  of  the 
uterus,  which  shows  itself  tluring  and  after  deliv(>ry  as  a  sometimes  fatal  puerperal 
fever. 


CHAPTER  XVII 
HYGIENE  OF  PREGNANCY 

Women  call  the  doctor  and  engage  him  for  their  confinement  earlier  now  than 
formerly,  earlier  anuMig  tiie  better  classes  than  tiie  poorer,  earlier  in  tin*  city  than 
the  country,  earlier  in  the  United  States  than  in  most  other  lands.  Many  advan- 
tages arise  from  this,  in  that  it  may  enable  the  doctor  to  learn  the  traits  or  constitu- 
tion of  his  patient,  watch  for  any  symptoms  of  disease,  and  prepare  her  properly  for 
the  labor.     It.  therefore,  should  l>e  encouraged  in  practice. 

Many  and  varied  (luestions  will  be  asked  of  the  accoucheur,  and  it  will  be  found 
convenient  to  supply  each  patient  with  a  folder  containing  instructions  for  her  to 
follow  anil  other  common  information.  In  a  general  way  the  gravida  should  not 
change  her  usual  mode  of  life  unless  the  physician  knows  that  some  of  her  habits 
are  bad. 

Dress. — The  dress  should  be  simple  and  warm.  Even  in  summer  woolen  under- 
clothing is  to  be  worn,  but  of  the  lightest  weight,  and  heavier  in  winter.  This 
rule  must  be  specially  enforced  in  cases  of  nepliritis.  All  the  clothes  should  hang 
from  the  shoulders  by  suspenders  or  corset-waist,  and  hea\y  skirts  not  worn;  better, 
warm  drawers,  closed,  to  prevent  infection  from  street  dust. 

Low-heeled  shoes  with  broad  toes  are  best.  The  pregnant  woman  throws  her 
head  ami  shoulders  back,  in  order  to  keep  her  balance.  This  makes  an  angle  in  the 
small  of  the  back  (see  Fig.  133,  p.  109)  and  gives  the  patient  a  peculiar  gait,  which 
did  not  escape  the  eye  of  Shakespeare,  who  called  it  the  ''pride  of  pregnancy." 
Elevation  of  the  heels  throws  the  body  still  more  forward;  th(>  woman  nmst  throw 
head  and  shoulders  further  back,  which  causes  pain  in  the  loins  and  stretching  of  the 
aijdomen. 

There  .should  l)e  no  circular  constriction  at  any  part  of  the  body,  which  means 
that  corsets,  tight  waistl)ands,  round  garters,  may  not  be  worn.  The  Latin  term 
for  the  condition  of  pregnancy  was  "incincta, "  without  a  girdle,  and  had  refer- 
ence to  the  custom  of  laying  off  the  girdle  as  soon  as  pregnancy  was  determined. 
In  multiparjB  with  a  tendency  to  pendulous  abdomen,  and  in  most  primipara; 
toward  the  end  of  pregnancy,  a  light-weight,  woven  alxlominal  supjiorter  will  be 
foimd  very  comfortable.  Most  women  prefer  one  of  the  maternity  waists  on  the 
market.  The  Patterson  supporter  and  the  Kal)o  Maternity  Corset  are  the  best 
types.  The  corset  is  particularly  injurious  during  jiregnancy,  because  it  forces  the 
uterus  and  child  down  into  the  pelvis  and  against  the  lower  abdominal  wall,  causing 
congestion  of  the  pelvic  veins  and  weakness  of  tlie  abdominal  mu.scles.  Too  tight 
corsets  also,  by  restraining  the  expansion  of  the  uterus,  cause  tleformities  of  the 
child;  for  example,  clul)-foot,  \\Ty-neck.  Women  who  wish  to  conceal  pregnancy 
b}'  tight  lacing  may  do  themselves  or  the  fetus  even  fatal  damage. 

Diet. — Simple,  not  strict,  rules  govern  the  diet.  The  amount  of  meat  and 
broths  should  be  small — not  more  than  four  ounces  of  m(>at  or  its  (Mjuivalent  in  fish 
or  eggs  jier  ilay.  Starches  fried  in  fat  and  rich  jiastry  should  l)e  avoidetl.  Cereals, 
vegetables,  ami  fruits  should  be  eaten,  especially  fruit,  to  loosen  the  bowels.  \\  ater 
is  taken  freely,  at  least  five  full  glasses  daily— sterilized  or  filtered.  Milk  anil, 
especially,  buttermilk  are  commend(Ml.  Alcohol  is  to  be  forl)idden.  first,  because 
of  the  danger.  exaggerate(l  during  pregnancy,  of  contracting  the  liipior  habit ;  sec- 
ond, because  of  its  demonstrable  l)ad  etfect  on  the  offspring,  a  fact  which  wai>  known

226  THE    HYGIENE   AND    CONDUCT   OF   PREGNANCY 

in  Biblical  times.  Samson's  mother  abstained  from  win(>  during  her  pregnancy. 
A  child  begotten  by  a  drunken  father  may  be  dull,  stui)id,  or  tliseased,  an  obser- 
vation made  by  Diogenes. 

Fat  women  may  restrict  the  hquids,  but  never  so  much  that  the  daily  amount 
of  urine  is  reduced  below  32  ounces,  and  a  moderate  general  decrease  of  the  diet 
is  permissible  for  them. 

Coffee  in  moderate  amounts  is  not  forbidden.  Some  popular  books  advise  a 
special  chet  to  reduce  the  l)one  salts  of  the  fetus — a  pernicious  recommendation, 
because  the  mother's  health  will  suffer  before  the  infant  is  affected,  and  in  all 
probability  fetal  rickets  would  result  if  an  effect  were  possible. 

In  general,  a  woman's  ordinary  habits  need  be  little  disturbed.  She  should  not 
overeat,  thinking  she  must  feed  two.  Special  rules  govern  the  diet  in  women  who 
have  contracted  pelves  (Prochownik's  diet),  renal  disease,  or  diabetes. 

The  Bowels. — ^Constipation  is  the  rule  during  pregnancy,  and,  if  neglected,  may 
lead  to  most  serious  consequences.  A  long-standing  habit  cannot  be  cured  at  this 
time,  wherefore  drugs  must,  usually,  be  resorted  to.  The  following  is  the  treatment 
pursued  by  the  author: 

First,  the  patient  should  make  it  an  unfailing  hal)it  to  go  to  stool  at  a  certain 
horn-  each  day.  The  best  time  is  shortly  after  breakfast.  Should  no  movement 
occur — and  straining  is  not  permitted — the  action  of  the  rectum  may  be  provoked  by 
a  glycerin  suppository  or  an  enema.  A  desire  to  go  to  stool  at  any  time  must  not 
be  resisted.  A  sufficient  amount  of  exercise  must  be  taken.  Abdominal  massage 
is  not  permissible  during  gestation. 

Second,  every  morning  just  after  rising  and  every  evening  just  before  re- 
tiring the  patient  should  drink  a  glass  of  cool  water  and  eat  some  fruit — an  apple  or 
an  orange.     Between  meals  water  is  to  be  drunk  freely. 

Third,  her  diet  should  contain  fruit  and  vegetables  in  abundance,  especially 
spinach,  peas,  beans,  barley,  tomatoes,  corn,  and  foods  of  this  kind.  They  give 
something  for  the  bowels  to  act  on,  but  one  cannot  use  so  much  of  them  as  in  the 
non-pregnant  state.  Tea  is  forbidden,  but  coffee  in  moderate  amount  allowed. 
Prunes,  figs,  and  dates  are  to  be  eaten,  with  care  to  chew  them  very  fine,  as  they  may 
cause  indigestion.  A  little  system  in  this  helps  a  great  deal,  probably  by  sug- 
gestion. Let  the  patient  begin  with  one  prune  a  day,  then  one  more  each  day  up  to 
ten  or  fifteen,  gradually  decreasing  the  number  as  the  need  disappears.  Agar  is 
being  given  lately. 

Fourth,  let  the  patient,  every  night  before  retiring,  inject  into  the  rectum 
4  to  6  ounces  of  ordinary  olive  oil,  leaving  it  there  all  night.  In  cases  of  spastic 
constipation  this  is  a  valuable  remedy. 

Fifth,  drugs  are  withheld,  as  far  as  possible,  and  active  cathartics  entirely. 
Cascara,  in  bitter  extract,  administered  in  capsules,  gives  the  best  results,  the  dose 
being  increased  gradually  and  decreased  as  the  desired  effect  is  obtained.  One  may 
alternate,  every  month,  with  a  saline  aperient,  and  of  the  many  on  the  market,  the 
author  has  found  Pluto  water  best.  Medicines  are  discontinued  as  soon  as  the 
patient  is  taught  to  do  without  them.  A  good  prescription  for  atonic  constipation 
attended  Avith  flatulence  is  the  following: 

I|.  Fluidext.  cascarae  sagradae 30 

Tr.  rhei  aromatici 30 

Tr.  nucis  vomica; 20 

Elixir  taraxaci  com.,  N.  F q.  s.  ad  120 

M.  et  S. — A  half  teaspoonful  after  meals,  t.i.d. 

If  the  patient  has  hemorrhoids,  aloes  may  be  substituted  for  the  cascara. 

The  Kidneys. — It  is  generally  conceded  that  the  kidneys  are  the  most  vulner- 
able ])oint  in  the  body  during  pregnancy.     One  surely  obtains  very  valuable  informa-

turn  of  the  general  metaV)olisin  from  the  urine,  ami  its  froquent  examination  is  a 
duty  of  tlic  accfjiiclu'ur.  The  woman  is  directed  to  send  liim  a  f(jur-<junee  l>ottleful 
of  the  morninji?  urine  every  thre<'  weeks  until  the  seventh  month;  then,  every  two 
weeks,  and  if  there  is  any  suspicion  of  nephritis  or  toxemia,  every  day.  She  is  also 
directed  us  often  to  measure  the  amount  passed  in  twenty-four  hcnirs.  Tliis  must 
be  not  h'ss  tlian  50  (nmces.  Tests  are  made  for  alhumin,  suf^ar,  sjx'cific  gravity, 
urea,  and  for  casts.  For  practical  i)urposes,  finer  examinations  are  not  necessary. 
Albumin  is  significant  if  found  by  the  usual  tests.  The  author  has  made  these 
urinalyses  for  years,  and  has  been  rewarded  in  discovering  and  forestalling  many 
cases  of  probable  eclamj^sia  and  toxemia  (see  Eclampsia). 

Exercise. — Violent  exercise,  of  course,  is  to  be  avoide(l.  It  is  n(jt  possil)le  to 
build  up  a  strong  muscular  system  during  i)regnancy.  That  should  have  been 
done  before.  To  be  avoided  are  jolts,  running,  sudden  motions,  lifting  great 
weights,  going  up  and  down  stairs  quickly,  horseback  riding,  cycling,  riding  over 
rougii  roails,  golf,  tennis,  dancing,  and  swimming.  Sea-bathing  is  adopted  by  some 
women  to  bring  on  abortion.  To  be  encouraged  are  walks,  up  t(j  two  miles,  in  the 
sunlight,  preferably  not  at  night,  and  carriage  drives.  Housework  is  desirable, 
unless  too  strenuous. 

Railway  travel,  the  automobile,  and  ocean  voyages  had  better  be  avoided,  and 
if  travel  is  necessary,  the  most  comfortable  accommodations  must  be  secured. 
Much  dei)ends  on  the  individual,  since  many  gravidic  do  the  most  remarkable 
things  and  suffer  nothing,  while  others  miscarry  from  the  slightest  provocation. 
If  a  woman  has  a  known  tendency  to  abort,  she  must  be  ver}'  careful,  and  had 
better  even  go  to  bed  at  the  usual  time  of  her  menstrual  periods.  A  general  mas- 
sage is  often  useful,  care  being  taken  to  avoid  the  breasts,  the  abdomen,  and  varicose 
veins. 

The  patient  may  go  to  the  theater,  but  must  avoid  crowds,  for  fear  of  getting 
into  a  crush.  She  must  avoid  gatherings  in  close  rooms,  especially  with  stove  heat, 
because  the  fetus  is  very  susceptible  to  coal-gas. 

Coitus  During  Pregnancy. — This  is  a  subject  on  which  much  has  been  WTitten, 
and  deservedly,  because  it  is  of  great  importance.  Many  women  have  a  distaste 
for  intercourse  during  this  time;  in  others  the  desire  is  increased,  rarely  to  nJ^npho- 
mania.     There  are  many  reasons  for  forl)idding  coitus  during  gestation: 

First,  the  danger  of  abortion,  which  is  caused  by  the  impact  of  the  penis 
against  the  cervix,  and  the  great  congestion  of  the  parts  during  the  act.  Xo  doubt 
the  frequency  of  miscarriage  in  the  newly  married  is  due  to  this  cause. 

Second,  the  nervous  shock  is  not  well  borne  by  a  woman  whose  nerve  energy 
is  already  overtaxed.  It  aggravates  the  leukorrhea,  and  often  increases  the  nausea 
and  vomiting.  In  some  cases  the  presence  of  the  husbantl  incites  an  attack  of 
vomiting,  and  removal  of  the  patient  from  home  may  be  necessary. 

Third,  animals  do  not  copulate  when  the  female  is  pregnant,  and,  while  the 
hal)its  of  other  animals  do  not  guide  man,  in  many  cases  it  would  be  wise  for  him  to 
follow  their  instincts. 

Fourth,  the  danger  of  infection.  This  is  a  real  tlanger,  the  author  knowing 
t)f  two  cases  where  fatal  sepsis  resulted  from  coitus  just  before  labor,  and  several 
other  cases  where  severe  ))ueri)eral  fever  was  in  all  likelihood  the  result  of  this  per- 
nicious i)ractice.  The  danger,  of  course,  is  greater  in  nuiltii)ane  in  whom  the  cervix 
is  ])atulous. 

Other  reasons  that  have  been  given  are  more  or  less  fanciful — for  exami)le, 
that  it  makes  the  child  sensual,  that  it  weakens  it,  that  the  wife  will  lose  resp)ect  for 
her  hus])and.  The  danger  from  coitus  is  greatest  in  the  first  three  months,  wlien 
usually  the  fact  of  pregnancy  is  not  always  sure,  and  in  the  last  three  months,  when 
the  abdominal  tumor  is  large  and  the  element  of  infection  mori'  prominent.     It  is 


228  THE    HYGIENE   AND    CONDUCT   OF   PREGNANCY 

wise  to  restrict  the  practice  to  the  intervening  months,  or,  better,  advise  against  it 
entirely. 

Pan-in  devotes  some  spare  to  this  subject,  and  refers  to  the  distaste  of  coitus  in  the  wife  as 
one  of  the  signs  of  pregnancy  mentioned  by  Susru-fa.  African  tribes  and  other  savages  forbid  it, 
the  Chinese  and  Indians,  likewise.  Tlie  Tahnud  forbids  it  conditionally.  Swift,  in  his  terrible 
satire  on  the  human  race,  in  "Cnilliver's  Travels  ,\mong  the  Ilouyhnhmns,"  says  that  "this  is 
such  a  degree  of  infamous  brutality  as  no  other  sensitive  creature  arrives  at,"  that  is,  "that  the 
She-yahoo  atlmits  the  male  while  sh(>  is  pregnant." 

*  The  ancicMit  Irans,  Medes.  and  Persians  punished  the  man  heaA-ily  for  such  an  act;  lie  re- 
ceived 2000  lashes  and  was  compelled  to  carrv  oOOO  loads  of  heavy  and  light  wood  to  the  fire, 
sacrifice  1000  small  animals,  kill  1000  snakes,  1000  land  lizards,  2000  water  lizards,  and  3000 
ants,  and  build  30  bridges  over  flowing  water  (Ploss). 

Bathing. — Cold  and  hot  baths,  Turkish  and  Russian,  hot  sitz-baths,  and  ocean 
bathing  are  to  l)e  avoided,  because  of  the  danger  of  exciting  uterine  contractions. 
Tepid  l:)aths,  Anth  cool  spongings,  may  be  taken  freely.  They  aid  the  kidneys  in  the 
work  of  excretion  and  preserve  the  person  from  odor.  During  pregnancy  the  skin 
secretes  more.  Sea-salt  baths  at  home  are  good,  but  if  the  patient  feels  exhausted 
afterward,  they  are  to  be  stopped.  A  light  general  massage  after  the  bath  is  very 
grateful  to  the  patient.  For  the  profuse  sweating  which  is  sometimes  an  annoj'ing 
s^^nptom,  a  bath  followed  In'  a  brisk  rub  vnih  a  ''salt  towel"  is  useful.  A  "salt 
towel"  is  made  bj'  wringing  a  ]:)ath-towel  out  of  a  strong  brine  and  drying  it. 

Among  the  poor  there  is  a  notion  that  bathing  during  pregnancy  is  dangerous. 
Is  it  possible  that  old  experience  discovered  some  harm  in  it?  We  know  that  the 
full  tub-bath,  during  or  near  labor,  may  cause  infection,  through  the  polluted  water 
gaining  entrance  to  the  vagina.  Therefore  the  author  advises  his  patients,  in  the 
latter  weeks  of  pregnancy  and  in  labor,  to  employ  only  the  shower. 

Vaginal  douches,  unless  indicated  by  disease,  are  not  to  be  used.  Only  mild 
antiseptics  may  be  employed,  tepid,  and  given  under  low  pressure,  12  to  18  inches. 
One  of  the  best  medicaments  is  potassium  permanganate,  gr.  v  ad  Oij.  Existing 
gonorrhea  must  be  treated  thoroughly,  to  avoid  conjunctivitis  in  the  new-born  and 
puerperal  accidents  in  the  mother. 

Mental  Occupation. — INIost  women  have  sufficient  to  do  in  their  household, 
and  the  question  of  an  especial  obstetric  literature  does  not  come  up.  Occasionally 
the  accouch(Hir  will  be  asked  to  recommend  a  book  on  the  subject  of  the  care  of  the 
mother  during  pregnancy.  There  are  many  on  the  market,  some  of  the  best  being 
"Wife  and  Mother,"  by  Pye  Henry  Chevasse,  and  one  by  Fry,  on  Maternity.  The 
author  questions  the  wdsdom  of  giving  gravidse  books  which  describe  the  anatomy 
and  physiology  of  the  function.     She  should  be  advised  to  avoid  them. 

Some  women  believe  that,  by  reading  fine  literature,  the  child  Avill  be  intellectual, 
by  studying  music,  musical,  ]>y  practising  the  arts,  artistic.  Since  these  enjoy- 
ments do  no  harm,  but  rather  keep  the  mind  away  from  injurious  thoughts,  the 
woman  may  be  humored  in  the  idea,  though  the  physician  may  express  a  gentle 
disbelief  in  the  notion.     This  l^rings  us  to  the  subject  of — 

Maternal  Impressions. — By  this  term  is  meant  those  impressions  on  the  mind 
or  body  of  the  cliild  in  utero  which  result  from  a  similar  impression  on  the  mind  or 
body  of  the  mother.  The  belief  that  if  a  pregnant  woman  should  see  an  ugly  or 
terrifying  object  it  would  be  reproduced  in  the  offspring  dates  from  remotest  an- 
ti(iuity,  and  is  spread  all  over  the  world,  even  in  darkest  Africa.  The  Biblical  story 
of  Jacob  and  the  ".speckled  and  spotted  kine"  proves  its  existence  in  the  civilized, 
and  the  practices  of  the  savages  in  many  parts  of  the  world  show  that  the  notion 
existed  among  the  uncivilized,  peoples  for  ages  (Ploss).  Novelists  (Goethe,  Scott, 
Dickens,  O.  W.  Holmes,  Shakespeare,  Sterne,  Ha^vthorne)  have  used  the  idea  as  a 
pet  theme,  and  many  names  great  in  nKnlicme  and  allied  sciences  could  be  quoted  in 
its  support.     A  few  are  Van  Swieten,  Boerhaeve,  Morgagni,  Rokitansky,  Burdach, 


HYGIENE    OF   PREGNANCY  229 

Stoltz,  Liebrecht,  Delassus,  Monteggia,  Montgomery,  Tyler  Smith,  Fordyce 
Barker,  Busey,  and  Parvin.  Nevertheless,  most  of  the  later  writers  eall  the  belief 
a  superstition,  absurd  and  harmful.  Blondel  (London,  1727)  fought  against  the 
theory.  It  nmst  be  admitted  that  the  belief  in  the  effect  of  the  nujther's  mental 
state  on  the  infant  cannot  be  proved  by  appeal  to  physical  laws,  l>ut  we  cannot 
always  prove  our  medical  beliefs  in  this  way.  We  admit  the  influences  of  heredity, 
which  we  cannot  as  yet  explain. 

The  arguments  against  the  theory  are,  first,  there  is  no  nervous  connection 
between  the  mother  and  the  fetus.  \'irch(nv  himself  could  find  none.  Second, 
the  child  is  completely  formed  at  the  end  of  the  sixth  week,  a  time  that  pregnancy 
is  usually  not  recognized,  and  in  most  of  the  ca.ses  reported  the  causative  mental 
shock  occurred  much  later  in  gestation.  Third,  all  tlie  monstrosities  observed  in  the 
human  are  found  in  the  lower  animals,  and  in  mucli  greater  number.  Many,  many 
women  see  ugly  or  striking  scenes  during  pregnancy  and  anxiously  ask  the  doctor  if 
the  baby  is  "marked,"  but  their  fears  are  seldom  realized.  It  would  seem  then 
that,  A\nth  our  present  scientific  knowledge,  the  belief  in  the  effect  of  the  mother'.s 
mind  on  the  phy.siad  well-l)eing  of  the  child  is  absolutely  unfounded.  How  can 
we  explain  the  innumerable  ca.ses,  many  reported  by  trustworthy  physicians,  where 
the  deformity  of  the  child  resembled,  in  most  striking  manner,  that  of  the  alleged 
shocking  experience  of  the  mother?  \'er3'  probably  by  coincidence,  if  pure  in- 
vention l^e  excluded. 

That  a  violent  emotion,  experienced  ])y  a  nursing  mother,  can  so  affect  the 
milk  that  the  nursling  gets  sick  from  it,  even  having  convulsions,  is  a  fact  attested 
by  honest  observers.  That  great  mental  excitement  can  produce  abortion  is  a  daily 
experience.  A  patient  of  the  author,  in  her  fifth  month,  was  much  frightened  by  fire 
in  an  adjoining  dwelling  and  aborted.  The  fetus  was  tangled  in  its  cord,  the  left 
leg  being  constricted  in  a  hard  knot.  The  author  performed  the  autopsy  on  an 
otherwise  healthy  but  macerated  fetus  weighing  nine  pounds.  During  a  severe 
thunderstorm,  a  week  previously,  the  mother  had  taken  fright,  the  child's  move- 
ments became  excessively  \4olent,  and  then  ceased.  The  labor  was  normal.  A 
hemorrhage  in  the  placenta,  due  to  circulatory  distur])ance  in  the  uterus,  \v\\\ 
explain  the  first  case,  but  there  was  no  suspicion  of  abruptio  placentte  in  the  second. 
These  facts  show  that  an  impression  on  the  mother's  mind  is  transmitted  to  the 
uterus,  but  they  do  not  explain  how  the  destructive  action  on  the  fetus  is  produced. 
Hemorrhages  into  the  chorion  may  interfere  Anth  the  nutrition  of  the  embryo,  even 
causing  its  death.  Lesser  tlegrees  of  interference  may  alter  the  growth  of  the  em- 
bryo, producing  a  monster,  since  we  know  that  the  various  cells  of  the  morula  are 
endowed  \\ith  unequal  resistance  to  external  influences.  ^Monstrosities  have  been 
produced  by  chemical  action  on  segmenting  eggs  (see  Teratology')-  If  the  emotions 
are  not  purely  nervous,  but  partly  chemical  in  action,  would  it  be  absurd  to  believe 
that  toxins,  produced  by  acute  and  chronic  emotional  contlitions  of  the  mother, 
passed  through  the  placenta,  as  other  chemicals  do,  and,  exerting  a  selective  action, 
as  many  toxias  do,  affected  the  delicate  nerve-cells  of  the  growing  embryo?  We 
know  tliat  physical,  mental,  temperamental,  and  emotional  traits  in  either  parent 
are  transmitted  to  the  offspring.  How  is  the  germ  plasm  affected  in  the  first  place, 
that  it  can  carry  these  delicate  but  permanent  impressions?  The  scope  of  this 
work  does  not  permit  going  deeper  into  the  subject,  nor  have  our  means  of  investi- 
gation been  all  tried  on  its  solution.     Perhaps  modern  biochemistry  will  explain  it. 

The  author  has  not  seen,  in  the  many  cases  of  supposed  maternal  impression 
n^ported  to  him,  even  a  plausible  connection  between  the  nervous  shock  and  the 
tleformity  of  the  cliild,  anil  ha.s  not  the  least  ground  for  believing  that  such  a  tera- 
togenic connection  could  exist.  Nor  have  his  ordinary  observations  discovered 
any  relation  l)etween  the  mind  of  the  mother  and  the  babe  that  could  not  be  ex- 
plained by  the  laws  of  heredity  as  we  at  present  understand  them,  but  that  such  an 


230  THE  HYGIENE  AND  CONDUCT  OF  PREGNANCY 

influence  may  go  from  one  to  the  other  should  not  he  ruled  out  as  absurd  and  in- 
discussable. 

When  the  gravitla  asks  the  (luestion,  "  Could  anything  I  have  done  or  seen  affect 
my  baby?"  a  question  that  is  so  often  put  in  great  trepidation  by  the  expectant 
mother,  the  physician  can  conscientiously  answer,  "No,  in  the  present  state  of  our 
scientific  knowledge  there  is  no  basis  for  such  fears."  He  can  say,  too,  that  a  quiet, 
well-ordered  mind  conduces  to  a  normal  pregnancy  and  healthy  offspring,  which 
Plato,  in  the  Seventh  Book  of  Laws,  recommencUnl. 

Care  of  the  Breasts. — The  breasts  require  care  even  from  early  infancy.  The 
number  of  women  unable  to  nurse  their  babies  is  enormous,  and  the  evil  effects 
are  noticeable  in  our  infant  mortality  tables.  The  number  of  women  able  but  un- 
willing to  nurse  is  small  antl  growing  smaller  every  year.  It  is  a  great  misfortune 
if  a  woman  cannot  nurse  her  infant.  The  prevention  of  mastitis  neonatorum  has 
already  been  mentioned.  Especially  in  the  growing  girl  do  the  mammae  and 
nipples  need  care,  and  when  they  develop  at  puberty,  provision  for  this  gro^^i:h  l^y 
proper  dress  should  be  made.     Pressure  and  injury  must  be  avoided. 

Some  women,  during  pregnancy,  require  some  form  of  bust  supiDorter  to  hold 
up  the  large,  heavy,  pendent  breasts.  This  supporter  often  forms  a  part  of  the 
"maternity  waist."  During  her  bath  the  patient  exercises  care  not  to  hurt  the 
glands.  The  fine,  branny  scales  which  accumulate  on  the  nipple,  if  allowed  to 
remain,  form  moist  crusts  and  lead  to  cracks,  fissures,  blisters,  and  infection.  The 
nipples  should  be  washed  frequenth^  Tidth  a  good  soap,  dried,  and  anointed  with 
solid  albolene,  cocoa-butter,  or  any  sterile  fat.  In  blonds,  red-haired  women,  and 
others  with  tender  nipples  a  lotion  that  is  very  slightly  astringent  may  be  used : 

1$.    Glycerite  of  tannin 15 

Spir.  lavandulse  comp 30 

Aquaj  destil SO 

After  this  has  dried  in,  the  nipples  are  to  be  anointed  with  the  unguent.  No 
strongly  astringent  washes  or  alcohol  may  be  used.  They  harden  the  nipple,  wdiich 
then  cracks  under  the  sucking  efforts  of  the  child.  The  skin  of  the  nipple  must  be 
made  soft  and  pliable. 

Inverted  nipples  (a  reversion  to  an  embryonal  type)  can  seldom  be  improved 
by  treatment.  If  the  nipple  is  undeveloped,  or  pressed  in  by  improper  dress, 
gentle  attempts  may  be  made  to  draw  it  out  with  the  fingers  during  the  last  six 
weeks  of  pregnancy. 

Preservation  of  the  Figure. — Naturally  and  properly,  women  are  desirous  that 
the  function  of  child-bearing  should  not  leave  the  person  in  an  ungainly  shape — 
for  example,  with  protuberant  abdomen.  The  most  common  complaint  is  that  the 
patient  develops  a  "high  stomach"  after  labor. 

It  may  be  remembered  that  the  Roman  w^omen  had  abortions  performed  so 
that  they  need  not  suffer  the  disfigurement  produced  by  child-bearing.  Certain 
changes  in  the  body  are  the  necessary  consequences  of  childbirth,  and  beautify  the 
figure,  although  some  women  do  not  look  at  it  in  this  light.  Such  are  the  rounding 
of  the  hips,  broadening  of  the  bust,  the  more  mature  and  matronly  appearance. 
It  is  natural  for  some  women  to  put  on  fat  after  delivery,  and  nothing  done  before, 
during,  or  after  confinement  will  prevent  it.  An  excessive  accumulation  is,  how- 
ever, amenable  to  the  usual  treatment  for  obesity. 

For  the  prevention  of  "high  stomach"  or  extreme  prominence  of  the  lower  ab- 
domen much  may  be  done.  The  condition  is  caused  by  weakness  of  the  abdominal 
muscles,  or  even  by  a  separation  of  the  recti  muscles — when  the  woman  is  said  to 
have  a  "rupture."  As  the  result  of  either,  the  intestines  fill  with,  gas  and  fall 
forward;  sometimes  the  kidneys  become  movable,  or  even  the  liver  descends.  The 
muscles  give  way  under  the  stretching  produced  by  the  growing  uterus,  and,  of 
course,  will  give  away  sooner  if  there  are  twins  or  an  unusually  large  child,  or  if  the 


HYGIENE    OK    PREGNANCY  231 

walls  are  weak.  If  corsets  arc  worn  (luriiiK  pr('f;:naiicy,  they  add  to  the  strain  on 
the  lower  al)ilonien,  and  thus  favor  muscular  weakness.  Hi^h-heeled  shoes  are 
another  factor.  Overstraining  during  labor  and  inattention  to  the  Ixjwels  after 
labor  are  also  causative.  To  prevent  the  muscular  insufficiency,  one  must  begin 
witli  the  girl.  She  should  develop  herself  as  does  the  boy,  with  active  sports — 
rowing,  swimming,  climbing,  etc.  \\'lien  a  young  woman,  she  should  not  *'lace" 
and  thus  jjaraly/e  the  alxlomen.  Healthy  exercise  of  the  whole  body  shoiild  form 
part  of  her  daily  routine.  The  abdomen  may  need  some  supi)ort  during  the  last 
three  months  of  pregnancy,  which  may  be  obtained  by  one  of  the  matemitj'  corsets 
recommended.  A  special  abdominal  binder  may  sometimes  be  needed,  e.^ipecially  in 
multipanc  with  already  weakened  walls  or  with  twins,  pohln'dramnicjs,  etc.  After 
the  birth  of  the  child  the  nurse  should  see  that  the  bowels  are  regularly  emptied 
and  that  gas  does  not  accumulate  in  the  intestines.  The  binder,  after  labor,  does 
not  prevent  "  high  stomach, "  and  while  the  \\Titer  recommends  it  (.see  Treatment  of 
the  Puerperium),  the  most  benefit  o1)tained  from  it  is  when  tlie  patient  first  leaves 
the  bed.  To  bring  the  abtlominal  walls  back  to  their  original  tonus  the  nurse  may, 
after  the  uterus  has  sunk  into  the  pelvis,  give  them  a  daily  five-minute  ma.ssage. 

To  prevent  the  overstretching  of  the  skin  and  the  forihation  of  the  linea?  or 
striai  gravidarum,  our  efforts  are  not  very  successful,  but  the  \\Titer  recommends 
skin  massage  with  albolene  or  fat.  Several  such  remedies  are  much  vaunted  in

Women  whose  legs  become  swollen  and  full  of  immense  varicose  veins  should 
wear  rubber  stockings.  Varicosities,  when  large  and  extensive,  are  a  congenital 
defect  and  unpreventable. 

General  Instructions. — In  general,  the  obstetric  case  is  to  be  treated  as  a 
major  surgical  case.  The  woman  is  requested  to  report  any  symptom  that  annoys 
her,  especially  headache,  edema  of  the  extremities,  bleeding  from  any  part  of  the 
body,  constipation,  diminished  urine,  nausea  and  vomiting.  It  is  wi.se  for  the 
l)iiysician  to  see  her  occasionally  during  ])regnancy,  and  judge  for  himself  if  her 
condition  is  satisfactory.  Women  comjilain  that  their  accoucheurs  do  not  take 
enough  interest  in  them — a  charge  which  is  true.  Instructions  are  to  be  given 
regarding  the  advent  of  labor,  how  the  patient  may  decide  that  it  is  at  hand,  and 
cortlial  encouragement  should  be  offered  her,  since  she  awaits  the  event  with  much 
anxiety  and  trepidation. 


THE  PREPARATION  FOR  THE  ASEPTIC  CONDUCT  OF  LABOR 
Unless  th(»  woman  is  to  go  to  a  maternity  for  delivery,  the  same  ])reparations 
must  be  made  at  home  as  for  a  major  surgical  operation  at  home.  Thousands  of 
mothers  and  children  die  every  year  because  of  the  lack  of  such  preparation,  and 
of  the  spirit  that  animates  it.  The  principles  of  a.sepsis  and  antisepsis  are  not  com- 
plicated nor  hard  to  apply.  They  are  only  two:  everything  that  is  to  come  in 
contact  with  the  puerjjeral  wounds  nuist  be  absolutely  sterile;  second,  the  external 
genitalia  and  introitus  vaginie  must  be  thoroughly  disinfected.  If  these  two  prin- 
ciples are  deeply  ingrained  in  the  accoucheur's  mind,  the  methods  of  carrying  them 
out  will  suggc^st  themselves.  The  jionderous  and  complicated  system  of  iv^ej^sis 
practised  in  hospitals  is  not  jiossible  nor  necessary  in  the  home;  but,  on  the  other 
hand,  the  ideals  of  asepsis  are  not  met  by  a  basin  of  bichlorid  solution  and  a  roll  of 
ab.sorbent  cotton. 

A  list  of  the  utensils  (a  copy  of  the  author's  lieing  rejiroduced  herewith) — 
dressings,  cottons,  brushes,  etc.^ — needful  for  confinement  is  to  be  supplied  each 
patient,  with  instructions  how  to  j^repare  same,  so  that,  when  the  time  comes, 
everything  is  in  readiness  for  an  aseptic  and  correct  accouchement.  The  nurse 
engaged  for  the  case,  two  weeks  before  the  day  set  for  labor,  goes  to  the  patient's 


232  THE    HYGIENE   AND    CONDUCT    OF    PREGNANCY 

home  and  sterilizes  a  supply  of  towels,  sheets,  cotton  sponges,  gauze,  umbilical 
pads,  vulvar  pads,  and  binders.  The  woman  herself  may  be  instructed  in  these 
matters.  In  the  cities  there  are  nurses  who  make  a  specialty  of  such  preparations. 
Among  the  poorer  classes  the  physician  may  have  to  carry  everything  necessary  for 
an  aseptic  labor  with  him. 

LIST  OF  ARTICLES  NEEDED  FOR  LABOR 

Three  hand-basins  of  granitowarc. 

Two  hand-brushes,  wooden  l)aeks. 

One  new  two-quart  douche-bag. 

An  Ideal  bed-pan. 

Rubber  sheeting  enough  to  cover  the  bed,  and  a  piece  a  yard  square. 

Twenty  yards  bleached  dairy  cloth  or  gauze. 

Two  pounds  of  sterile  absorbent  cotton. 

Five  yards  borated  gauze  in  sealed  jar. 

One  hundred  bichlorid  of  mercury  tablets. 

Four  ounces  of  lysol. 

Four  ounces  of  boric-acid  crystals. 

One  ounce  of  camphorated  oil. 

Four  ounces  of  sohd  albolene. 

A  bundle  of  new  newspapers. 

The  basins,  brushes,  and  douche-bag  are  carefully  sterilized  in  dust-proof  bags. 
One  pound  of  the  cotton  is  made  into  pledgets  or  sponges  of  convenient  size,  packed 
into  glass  jars,  and  sterilized.  The  other  pound  is  made  into  large  \aalvar  pads, 
covered  vrith  gauze.  These  are  sterihzed  in  packages  of  six.  The  newspapers  are 
sterilized  by  steam  vnth  the  pledgets  and  pads,  or  by  baking  in  the  oven,  and  serve 
many  purposes — for  example,  to  WTap  up  basins,  towels,  sheets.  Mason  jars,  etc., 
that  have  been  sterilized  before  labor,  to  place  under  the  patient  during  labor,  and 
to  lay  on  tables  and  chairs  to  avoid  marring  them.  A  sterile  newspaper  ^Tapped 
in  a  sterile  towel  makes  a  good  bed-pad  during  delivery.  After  everything  has  been 
sterilized,  the  packages  are  labeled  and  put  away  in  a  clean  drawer  or  trunk. 
Maternity  outfits  containing  all  the  needed  utensils,  gauzes,  dressings,  pads,  sheets, 
towels,  etc.,  already  sterilized,  and  neatly  packed  in  sealed  containers,  are  sold  by 
surgical  supply  houses.  At  the  time  of  labor  the  accoucheur  finds  things  all  pre- 
pared and  ready,  a  most  comforting  feeling.     Well  prepared  is  half  the  battle. 

RULES  FOR  PREGNANT  WOMEN 
(This  set  of  rules  is  printed  on  the  reverse  side  of  the  slip  gi\'ing  the  Ust  of  articles  needed  for  labor.) 

1.  Consult  your  physician  as  soon  as  you  suspect  pregnancy. 

2.  Dress  warmly,  mth  wool  next  the  skin.  Avoid  circular  constriction  at  any  part  of  the 
body.  As  soon  as  pregnancy  is  determined,  lay  off  corsets;  wear  a  maternity  waist  and  bust 
supporter. 

3.  Take  plenty  of  mild  exercise  in  the  open  air,  especially  walking,  stopping  short  of  fatigue. 
Avoid  \'iolent  motions,  golf,  tennis,  swimming,  long  trolley  or  automobile  rides,  etc. 

4.  Takenohot  or  cold  baths;  in  the  last  two  weeks  no  tub-baths;  use  the  shower  and  spong- 
ing. Take  no  douches  unless  ordered,  and,  especially  in  the  last  month,  allow  nothing  to  touch 
the  internal  genitalia. 

5.  The  bowels  must  move  every  day. 

6.  Eat  your  usual  amount  of  food,  restricting  the  meats  or  their  equivalents,  fish  and  eggs, 
to  four  ounces  a  day.     Drink  freely  of  water,  milk,  and  buttermilk. 

7.  Keep  the  breasts  free  froin  pressure.  Bathe  the  nipples  once  a  week  with  tincture  of 
green  soap  and  anoint  them  daily  with  sterilized  all)olene. 

8.  Send  a  four-ounce  specimen  of  the  morning  urine  for  examination  every  three  weeks; 
after  the  seventh  month,  every  two  weeks. 

9.  During  the  eighth  month  a  careful  examination  must  be  made,  and  near  term  another. 
10.  Report    to    your    physician  when  you  are  troubled  with  nausea,  vomiting,  headache, 

swelUng  of  the  feet  or  eyelids,  or  oth(>r  al)normal  sjTnptoms.     Report  also  any  marked  reduction 
in  the  amount  of  urine,  and  if  there  is  hemorrhage,  however  slight,  from  any  part  of  the  botly. 

IL  When  labor  pains  begin,  or  if  the  waters  break,  or  if  the  show  of  blood-stained  mucus 
appears,  call  your  nurse  and  notify  the  accoucheur. 

The  Physician's  Examinations. — It  is  wise  for  the  accoucheur  to  make  a 
complete  general  and  pelvic  examination  of  every  woman  when  she  engages  him  to

take  care  of  her  during  confinement.  He  may  discover  a  contracted  pelvis,  an  ex- 
tra-uterine prcfiuaney,  an  ovarian  tumor,  (jr  other  condition  which  may  be  removed 
at  tliis  time  safely  for  the  patii-nt,  wliile  if  k-ft  for  cliance  discrjvery,  tlie  favorable 
period  may  have  passed  by.  Further,  he  must  make  sure  that  the  woman  is  preg- 
nant, to  spare  himself  mortifying  surprises.  The  woman  will  not  object  to  the 
examination  if  its  necessity  is  explained.  A  card  or  history  sheet  should  be  filled 
out  at  this  first  visit,  which  should  contain  a  complete  medical  history  of  the  pa- 
tient. This  may  bear  on  the  obstetric  side  of  the  ca.se.  The  card  used  by  the  author 
is  reproduced  on  p.  247,  Fig.  279.  The  urinalyses,  the  results  of  examinations, 
and  items  of  interest  during  the  course  of  pregnancy,  are  recorded  on  the  card. 


Fig,  2C0. — Bacdeujcque-Breiskt  Pelvimeter. 
\'ery  slightly  inixlified  by  the  author. 


Every  week,  at  a  time  set  ajxirt  for  the  purpose,  the  physician  looks  over  these  cards 
and  gets  in  touch  with  the  individual  i)atients.  If,  for  example,  the  record  shows 
that  no  urinalysis  has  been  made  for  a  long  time,  the  patient  should  be  reminded  of 
such  a  necessity. 

When  the  call  to  a  labor  comes,  the  card  should  be  taken  to  the  case.  The 
young  practitioner  is  advised  to  use  the  history  sheet,  reproduced  in  the  Appendix, 
in  the  early  years  of  his  practice.  It  has  not  the  advantage  of  convenience  of  the 
card,  but  it  is  more  detailed  and  more  complete.  It  will  develop  habits  of  thor- 
oughness and  broaden  his  mind.     In  later  vears  he  will  be  too  busv  to  fill  out

detailed  records,  then  the  card  will  afford  liiin  sufficient  space  for  the  inijiortant 
and  necessary  entries.  The  keeping  of  accurate  and  complete  records  is  a  duty 
which  the  physician  owes  his  patient,  his  profession,  and  liimself. 

Some  time  during  the  eighth  month  the  patient  should  be  thoroughly  exam- 
ined. This  examination  is  best  made  in  a  maternity  on  the  delivery  bed,  with  the 
patient  undressed.  It  can  be  conducted  at  the  patient's  home  or  even  at  the  physi- 
cian's office,  though  not  as  thoroughly.  While  the  greatest  attention  is  paid  to  the 
pelvis,  the  heart  and  lungs  should  be  studied,  "\Adth  a  view  to  discover  any  defects 
that  might  jeopardize  the  pregnancy  or  the  patient  in  labor.  The  size  and  con- 
sistence of  the  breasts  and  the  configuration  of  the  nipples  are  studied  with  a  view 
of  determining  the  woman's  ability'  and  fitness  for  lactation.     Far  from  objecting,

the  patient  \v\\\  approve  of  such  care  and  thoroughness  in  the  study  of  her  case,  and 
it  will  give  her  increased  confidence  in  her  accoucheur.  After  the  chest,  including 
the  breasts,  has  been  examined  and  the  information  noted  on  the  history  sheet  or 
card,  the  patient  is  arranged  lengthwise  on  the  bed  or  table,  the  abdomen  bared, 
the  chest  and  extremities  being  appropriately  draped  with  sheets,  and  all  the  in- 
formation that  may  be  gained  by  alxlominal  examination  is  sought  and  recorded. 
One  notes  the  size,  shape,  and  consistence  of  the  uterus,  the  position  and  size  of  the 
fetus,  its  heart-tones,  and  the  presence  of  abdominal  tumors  beside  the  uterus. 
The  external  pelvic  measurements  are  now  taken,  using  a  pelvimeter  (Fig.  260). 
The  following  are  the  most  useful : 

1.   The  distance  between  the  spines  of  the  ilia,  always  taking  the  outer  lip. 
The  distantia  spinarum  iliorum,  or  Sp.  I.  =  26  cm.

2.  The  distance  between  the  crests  of  the  iliu,  taking  the  outur  lip,  the  dis-

3.  Between  the  f^reat  tiDclianters,  distantiu  l)itrochanteriea,  or  Bi.T.  =  3i  cm. 

4.  From  the  depression  under  the  hist  iun»l>ar  spine  to  the  anterior  surface  of

The  author  takes  the  obhques  only  in  cases  where  there  is  scohosis  and  other 
evidence  of  pelvic  asynunetry.  Fig.  262  illustrates  the  manner  of  taking  the 
external  diameters.  Haudelocque's  iliameter  is  i)est  obtained  when  the  patient  is 
erect,  as  in  Fig.  203,  but  one  can  get  it  with  the  imtient  lying  on  the  side,  with  the 
upper  leg  straigiit.  the  lower  drawn  well  up  against  the  belly.  The  jiosterior  branch 
of  the  pelvim(>ter  is  jilaced  in  the  dimple  under  the  last  lumbar  spine.  This  point 
is  one  inch  above  a  line  drawn  between  the  two  posterior  superior  spines.  On  the 
posterior  aspect  of  the  pelvis,  in  wi'll-formed  women,  is  a  diamontl-shaped  depression

THE  HYGIENE  AND  CONDUCT  OF  PREGNANCY 


formed  by  the  dimples  of  the  posterior  superior  spines  of  the  iha,  the  lines  formed 
by  the  gluteal  muscles  and  the  groove  at  the  end  of  the  spine.  It  is  called  the 
rhomboid  of  ^lichaelis,  and  is  seen  on  beautiful  statues — for  example,  the  Capito- 
line  Venus  (Fig.  264).  The  point  for  the  calipers  is  near  the  apex  of  the  rhom])oid. 
Variations  in  the  shape  and  size  of  this  landmark  give  us  valuable  information  in 
deformed  pelves.  Anteriorly,  the  knob  of  the  pelvimeter  comes  to  rest  on  the 
most  prominent  portion  of  the  bony  pubis.  It  is  wise  to  take  Baudelocque's 
diameter  three  times  and  use  the  average  of  the  three  measurements.

Fig.  265. — DeLee's  Intehnal  Pel- 
vimeter. 


The  circumference  is  taken  with  the  tape  lying  Ijetween  the  crests  of  the  iha 
and  the  trochanters  on  each  side,  and  in  a  plane  perpendicular  to  the  long  axis  of 
the  body.  Naturally,  in  fat  women  the  circumference  does  not  give  valuable  in- 
formation. Indeed,  the  value  of  the  external  measurements  is  but  relative.  Only 
marked  deviations  from  the  normal  indicate  a  contraction  of  the  pelvis,  and  one 
must  rely  on  the  internal  examination  for  more  positive  information. 

Baudelocque  believed  that,  by  deducting  8  cm.  from  the  external  conjugate, 
the  length  of  the  vera  could  be  ol)taine(l.  This  is  not  true,  because  the  thickness  of 
the  bones  and  their  conformation,  produce  differences  of  even  53^  cm.  (Skutsch  and

Goenner).  The  author  possesses  a  pelvis  with  an  external  conjugate  of  18  cm.  and 
a  C.V.  of  14  em.,  and  another  with  an  external  conjugate  of  21  cm.  and  a  C\. 
of  9}/2  cm.  If  a  woman  lias  a  conjugata  externa  of  less  than  18  cm.,  the  probabil- 
ities are  strong  that  the  inlet  is  also  narrowed. 

For  the  same  reason  the  other  measurements  are  unreliable.  The  author  has  a 
pelvis  ^^^th  an  intercristous  diameter  of  21  cm.  and  an  internal  transverse  of  13^ 
cm.  The  relation  between  the  interspinous  and  intercristous  diameters  is  of  more 
importance,  for  when  the  interspinous  chameter  is  equal  to,  or  greater  than,  the 
mtercristous,  we  suspect  a  flat  pelvis.  (See  Chapter  LIV.)  The  author  insists  on 
internal  pelvimetry  in  all  cases,  excepting  only  those  women  who  have  had  one  or 
more  large  children  without  the  slightest  difficulty. 

The  internal  measurements  are  taken  wnth  the  hantl  and  a  special  internal 
pelvimeter  (Fig.  265).     These  are  essential:

1.  The  conjugata  diagonalis,  C.T>.  =  i2}/2  cm. 

2.  The  distance  between  the  spines  of  the  ischia,  bispinous,  Bi-sp.  =  ii. 

3.  The  distance  between  the  tuberosities  of  the  ischia,  Bi-isch.  =  ii  cm. 

4.  The  distance  from  the  end  of  the  sacrum  to  the  liganientum  arcuatum 
pubis;  sacropubic,  S.P.  =  ii  cm. 

Of  the  scores  of  instrumental  methods  of  measuring  the  conjugata  vera 
directly,  since  the  first  by  the  elder  Stein  (1772)  up  to  the  latest  by  Biliyky 
(1909),  not  one  has  proved  practical  (Fig.  266).  Their  application  is  too  pain- 
ful and  difficult.  We  still  obtain  our  best  information  by  measuring  the  conju- 
gata diagonalis  and  deducing  from  it  the  length  of  the  C.V.  Even  though 
we  can  measure  the  height  of  the  pubis,  and  thus  know  the  length  of  two  sides 
of  the  triangle,  it  is  impossil^le  to  learn  the  arc  of  any  of  the  angles  of  the  tri- 
angle subtended  by  the  symphysis.  Trigonometry,  therefore,  cannot  help  here — 
we  must  depend  on  estimates.  Examination  of  large  numl^ers  of  pelves  shows  that 
if  one  deducts  13^  cm.  from  the  length  of  the  CD.,  one  obtains  the  length  of  the 
C.V.     If  the  pubis  is  very  high,  6  cm.  or  more  (Fig.  267),  one  must  deduct  2  or  2^

cm.  If  the  upper  border  of  the  pubis  inclines  more  than  usual  toward  the  sacrum 
or  is  very  thick,  or  if  there  is  an  exostosis  of  the  posterior  surface  of  the  synii)hysis, 
both  of  wliicii  last  occur  in  rachitic  pelves,  2  or  even  ii  cm.  may  have  to  be  deducted 
from  the  length  of  the  CD.  (Fig.  2G8j. 

The  transverse  diameter  of  the  pelvis  decrea.ses  from  aijove  downward.  At 
the  level  of  the  inlet  it  measures  12  to  13  cm.;  in  the  region  of  the  spines,  11 
cm.;  anterior  to  the  spines,  11^4  to  12  cm.;  at  the  outlet,  between  the  tuberosities, 
11  cm.  In  practice,  it  is  only  exceptionally  i)ossibl('  to  mea.sure  the  transverse  of 
the  inlet  directly.  When  labor  ha.s  been  in  progress  for  a  time,  the  vagina  becomes 
so  soft  antl  distensible  that  one  can  spread  the  branches  of  the  internal  pelvimeter, 
picturetl  in  Fig.  205,  until  they  touch  both  sides  of  the  pelvis,  enabling  one  to  read 
off  the  measurement  on  the  scale  with  mathemati'-al  accuracy.  Late  in  pregnancy 
it  is  easy  with  this  instrument  to  measure  the  distance  between  the  .><pines  of  the 
ischia.  The  distance  between  the  tuberosities  is  not  so  easily  gotten,  because  of  the 
thick  padding  of  fat  over  the.se  bones.     One  must  adfl  1  to  2  cm.  to  the  mcasure-

ment  obtained  with  the  pelvimeter.  While  the  external  measurements  give  only 
efjuivocal  information,  con.siderable  dependence  may  be  placed  on  internal  men- 
suration, and  this  will  increa.se  with  added  experience. 

Technic  of  the  Internal  Examination. — During  the  early  part  of  the  eighth 
month  is  the  most  fav()ral)le  time  for  pelvic  mensuration  in  general  practice.  Dur- 
ing lal)or  one;  may  have  the  atlvantage  of  anesthesia.  The  patient  must  lie  across 
the  bed  or  on  a  table,  with  the  hijjs  hanging  well  over  the  edge,  to  enable  the  examiner 
to  sink  his  elbow.  Her  person  nmst  be  draped  with  a  sheet,  but  the  genitalia  are  to 
be  exposed.  For  examination,  at  this  period,  the  genitals  need  not  be  shaved,  but 
they  .should  be  wasiicd  with  water  and  soap,  following  this  with  a  liberal  u.^e  of 
anti.septic  solution,  1  :  1500  bichlorid  or  1  per  cent,  lysol.  Rubber  gloves  are  worn 
by  the  author  as  a  precaution  again.st  .syphilitic  infection,  for  the  sake  of  personal 
cleanliness,  to  preserve  the  skin  from  the  corrosive  action  of  antiseptics,  and  to 
render  the  examination  less  jxiinful  to  the  jiatient.  The  internal  pelvimeter  is 
sterilized  by  boiling  in  a  1  jxt  cent,  soda  or  i)orax  solution.  On  insjK'cting  the  vulva,

lacerations,  etc.,  after  which  two  fingers  are  inserted  between  the  -widely  separated 
labia,  deeply  into  the  vagina.  It  is  well  to  study,  in  each  case,  the  topography  of  the 
levator  ani,  which  can  be  easily  done  b>'  pressing  the  fingers  down  on  either  side  of 
the  vagina.  The  powerful  broad,  sling-like  muscle  of  a  primipara  contrasts  strongly 
with  the  thick,  cord-like  muscle  of  a  multipara.  The  condition  of  the  vagina  is 
noted.  If  there  is  a  granular  condition  of  the  mucous  membrane  which  might 
suggest  gonorrhea,  a  smear  should  be  taken  with  a  view  of  preventing  ophthalmia 
neonatorum  and  sepsis  postpartum.     Next,  the  cervix  is  studied  to  learn  whether

it  is  long,  tapir-nose-like,  or  short  and  lj»road;  whether  patulous,  as  in  multiparae,  or 
closed;  whether  normal,  smooth,  and  soft,  or  diseased,  thick,  knobby  (ovula  Na- 
bothi),  catarrhally  inflamed,  or  eroded.  Then  the  lower  part  of  the  uterus  is  pal- 
pated and  the  presence  of  the  head  determined,  at  the  same  time  discovering  any 
tumor  which  may  block  its  entrance  into  the  pelvis.  The  fingers  now  pass  around 
the  bony  walls  of  the  pelvis  to  obtain  a  mind  picture  of  the  capacity  and  configura- 
tion of  the  excavation.  It  requires  years  of  practice  for  the  accoucheur  to  be  able 
to  form  correct  mind  pictures  of  these  things,  but  they  must  be  learned.  The  height 
of  the  pubis,  its  inclination  into  the  inlet,  the  presence  of  an  exostosis  on  its  posterior

hips  are  horizontal,  the  blades  are  spread  in  the  horizontal  plane  until  they  are 
arrested  by  the  Iwny  walls  of  the  pelvis,  and  at  this  instant  the  amount  of  separation 
is  read  off  the  scale.  This  measurement  will  cause  little  pain  if  the  vagina  is  soft 
and  dilatable  (which  is  usual  at  this  time),  and  if  the  examiner  proceeds  slowly  and 
gently.  If  the  vagina  is  diseased,  it  is  more  tender.  Under  no  circumstances  may 
force  be  used,  as  a  tear  of  the  vagina  might  occur.  If  the  blades  easily  spread  to 
10  cm.  and  there  seems  to  l)e  room  beyond,  it  is  not  necessary  to  insist  on  the  full 
measurement.  In  a  contracted  pelvis  it  is  easier  to  obtain  the  distance.  To  take 
the  sacropubic  diameter  from  the  inside  is  not  always  possible  without  anesthesia, 
and  less  often  in  primiparse  in  whom  the  perineum  rises  high.  Fig.  270  shows 
how  it  is  done.  One  knob  is  steadied  by  the  outside  hand  against  the  ligamcntum 
arcuatum  at  the  side  of  the  clitoris,  while  the  other  knob  is  pressed  against  the  end 
of  the  sacrum,  being  guided  into  place  by  the  fingers  in  the  vagina.  One  may  mea- 
sure the  sacropubic  diameter  with 
the  fingers  in  the  same  manner  as  one 
obtains  the  diagonal  conjugate.  Now 
the  instrument  is  removed  and  the 
examiner  takes  the  conjugata  di- 
agonalis  (Fig.  271). 

Sinking  the  elbow  and  resting  it 
against  the  knee,  the  examiner  gently, 
but  wdth  force,  presses  the  middle  fin- 
ger-tip against  the  promontory  of  the 
sacrum.  It  may  be  necessary  to  keep 
up  a  steady  pressure  against  the  peri- 
neum for  several  minutes  before  the 
rigid  muscles  will  relax.  As  soon  as 
the  tip  of  the  promontory  is  felt,  the 
hand  is  raised  against  the  ligamen- 
tum  arcuatum.  A  bit  of  cotton  car- 
ried on  the  index  of  the  other  hand  is 
now  pushed  along  the  index  of  the 
examining  hand  until  it  rests  at  the 
point  where  the  examining  hand  is 
touched  ])y  the  ligamentum  arcu- 
atum. After  making  sure  that  the 
middle  finger-tip  was  actually  resting 
on  the  promontory  at  the  time  the 
bit  of  cotton  reached  the  under  edge 
of  the  pubis,  the  cotton  is  carefully 
steadied  in  its  place  by  the  outside  hand  while  the  internal  hand  is  removed  from 
the  vagina.  With  a  tape-measure  or  any  pelvimeter  one  now  obtains  the  length 
of  the  conjugata  diagonalis  (Fig.  272).  After  guessing  at  the  inclination  of  the 
pubis  and  allowing  for  its  height,  one  deducts  1)^  or  2  or  more  cm.,  and  thus 
approximates  the  length  of  the  C.V. 

Several  methods  may  be  practised  in  obtaining  the  bituberal  or  biischiatic 
diameter.  Schroder  made  marks  on  the  skin  of  the  buttocks  to  show  the  location 
of  the  inner  surface  of  the  tuberosities  and  measured  the  separation  of  the  marks. 
An  assistant  may  measure  the  distance  between  the  two  thumbs  so  placed  on  the 
tubers  that  the  finger-nails  represent  their  inner  surfaces.  Two,  three,  four,  or  five 
knuckles  of  the  hand  may  be  pressed  in  between  the  bones,  and  the  distance  across 
them  later  measured  with  a  tape.  Williams'  pelvimeter  may  be  used  or  the  internal 
pelvimeter  shown  above.  The  closed  knobs  are  inserted  ])etween  the  bones  and 
separated  until  they  are  arrested  (Fig.  273).  It  is  necessary  to  press  the  tissues  well 
against  the  bone  and  to  add  1  to  Ij/^  cm.  to  the  reading  for  the  thickness  of  the  fat.

243 


The  sacropubic  diameter  may  also  be  taken  from  tlie  outside  In-  Breisky's 
method  (Fig.  274).  One  knob  of  the  j)elvimeter  rests  under  the  arch  of  the  pubis, 
the  other  is  pressed  against  the  .sacrococcygeal  joint,  1  cm.  being  deducted  from 
the  reading  to  obtain  the  result. 

Finally,  the  examiner  carefully  palpates  the  accessible  bony  portions  of  the 
pelvis.  The  fingers  of  each  haml  are  laid  on  the  de.scending  rami  of  the  pubis  and

of  the  bones,  asymmetry  of  the  two  sides,  a  i)eak-shaped  pubis  (osteomalacia,  rickets, 
see  Chapter  LIV),  are  thus  discovered  (Fig.  27G).  As  the  last  UKUueuver,  the  hand 
is  laid  flat  on  the  sacrum,  the  middle  finger  pressed  firmly  into  the  genital  crease,  to 
conform  to  the  curve  of  the  bone.  On  removing  the  fixed  hand,  the  external  con- 
figuration of  the  sacrum  can  be  seen  at  a  glance  (Figs.  277  and  27S). 

A  study  of  the  general  makeup  of  the  gravida  will  tell  us  a  great  deal.     Tall, 
muscular  women  seldom  have  contracted  pelves,  ami,  if  they  do,  the  tyi)e  is  usually 


244 


THE    HYGIENE   AND    CONDUCT   OF    PREGNANCY 


masculine.  Short,  petite  women  may  have  generally  contracted  pelves.  A  woman 
that  limps,  or  is  hunchbacked,  or  has  crooked  legs,  may  have  a  distortcnl  pelvis. 
Evidences  of  rickets  should  alwaj^s  be  sought  in  the  rachitic  rosarv,  the  square, 
large  head,  enlargement  of  the  epiphyses,  bow-legs,  curvature  of  the  spine,  etc. 

Much  more  could  be  written  on  pelvic  mensuration,  but  little  that  is  practical.  Rontgen 
photography  (BudinJ  has  failed  to  give  accurate  results,  as  far  as  mensuration  is  concerned,  but  it 
does  give  some  idea  of  the  shape  of  th(>  pelvic  cavity.  (See  Chapter  LIV.)  Cliseometry  is  a  method, 
devised  by  Nt^uman  and  Ehrenfest,  for  taking  the  inclination  of  the  pelvis.  The  cliseometer 
invented  by  them  gives  fairly  satisfactory  readings,  but  the  information  is  of  little  practical  value. 
They  also  devised  an  instrument  liuilt  on  the  lines  of  the  ordinary  pantograph,  with  a  spirit-level 
for  obtaining  accurate  outlines  of  the  entire  pelvic  parietes.  While  the  results  are  usable,  the 
application  of  the  instrument  is  quite  painful  and  complicated,  precluding  its  employment  as  a 
routine.

Method. 


All  this  information  is  to  be  carefullj^  entered  on  the  history  sheet  or  cartl  (Fig. 
280) .  If  the  physician  conducts  his  examination  systematically,  he  will  not  overlook 
any  point  s  and  have  the  disagreeable  necessity  of  putting  the  patient  back  on  the  table. 
On  discovering  anything  unusual  in  the  pelvis,  soft  parts,  or  child,  the  examination 
takes  on  extra  interest,  and  special  attention  will  have  to  be  directed  to  the  part. 
A  discussion  of  tliese  special  subjects  will  be  found  under  the  appropriate  headings. 
A  careful  consideration  of  all  the  information  obtained  enables  the  accoucheur  to 
make  his  diagnosis  of  the  case,  the  prognosis  of  the  labor,  and  any  recommendation 
for  treatment  at  this  time,  all  of  whicli  are  noted  on  the  card.  Too  much  emphasis 
cannot  be  laid  on  the  importance  of  making  a  careful  pelvic  mensurati'm  in  i^reg- 
nancy.  It  may  discover  a  contracted  pelvis  and  permit  us  to  induce  lal)or  while 
the  child  is  small,  or  prepare  for  cesarean  section  or  other  operative  delivery  at  tc^ni. 
It  will  explain  many  anomalies  in  the  mechanism  of  labor,  and  it  will  save  many 
mothers'  and  children's  lives. 

Visit  Before  Labor. — It  is  not  wise  to  allow  tiie  gravida  to  go  into  lal)or  with

one  may  expect  a  boy  with  the  same  slight  degree  of  confidence.  The  patient  is 
advised,  however,  that  the  doctor  is  only  guessing.  There  are  no  other  means  of 
distinguishing  the  sex  before  labor.

The  pliysifiun  satisfies  himself  that  the  woman  is  in  the  best  possible  physical 
condition  to  undergo  tlie  strain  of  delivery,  and  this  is  a  matter  not  lightly  settled.

are  towels,  sheets,  cotton,  basins,  etc.,  all  sterilized,  reaily  for  the  event. 


248  THE  HYGIENE  AND  CONDUCT  OF  PREGNANCY 

At  this  visit,  unless  previously  instructed,  the  woman  is  told  how  to  decide  that 
labor  has  begun,  and  when  to  call  the  accoucheur  and  nurse,  and  what  physician  to 
summon  in  the  event  of  an  emergency,  when  the  regular  attendant  is  not  obtainable. 
She  is  advised  not  to  take  tub-baths,  to  keep  the  bowels  very  free,  to  limit  the  meat 
in  her  diet,  and  to  drink  a  great  deal  of  water. 

The  Engagement  of  the  Nurse. — An  accoucheur's  success  in  obstetrics  depends 
largely  on  the  nurse.  A  careless  nurse  can  vuido  his  best  work.  After  the  diagnosis 
of  the  time  of  labor  is  made,  the  nurse  is  engaged  and  holds  herself  in  readiness  for 
a  call  for  that  time.  The  physician  should  select  the  nurse,  the  woman's  preferences 
in  the  matter  being  consultetl  only  when  they  agree  with  his.  A  good  nurse  possesses 
these  qualifications:  She  should  be  neat,  clean,  strong,  healthy,  and  in  love  with 
her  work;  she  should  be  a  graduate  of  a  training-school  where  she  has  had  special 
obstetric  training,  and  she  should  be  well  acquainted  with  the  methods  of  her 
phj^sician;  she  should  be  s^Tiipathetic  and  agreeable  to  the  patient,  and  withal 
loj'al  to  the  accoucheur;  she  should  not  be  a  tale-bearer,  should  not  quarrel  with 
the  servants  in  the  house,  ])ut  should  be  tactful  in  all  her  actions.  Such  nurses  are 
in  great  demand,  and  it  is  well  for  each  obstetrician  to  have  several,  specially  trained 
for  his  own  needs,  at  his  service.  Unless  the  accoucheur  has  a  staff  of  such  nurses, 
it  is  advisable  for  him,  if  he  wishes  to  avoid  mistakes  and  meddlesome  interference 
on  their  part,  to  provide  a  list  of  printed  instructions  regarding  the  care  of  the 
mother  and  babe  during  labor  and  puerperium.  The  author  refers  his  nurses  to  a 
book  wTitten  by  him,  "Obstetrics  for  Xurses,"  and  thus  avoids  a  great  deal  of  de- 
tailed exjDlanation. 

IXSTRUCTIOXS  FOR  THE  OBSTETRIC  XURSE 

Ten  days  to  two  weeks  Ijefore  the  date  of  expected  labor,  A-isit  the  patient  and  prepare  the 
materials  needed  for  confinement.  See  that  everytliing  on  the  list  of  articles  needed  (p.  232)  is 
at  hand. 

Basins,  bed-pan,  brushes,  douche-bag,  and  all  utensils  are  carefully  sterilized  b}'  steam; 
the  Kelly  pad,  by  soap  and  water  and  soaking  in  1:1000  bichlorid  for  three  hours;  the  douche- 
bag  is  to  be  boiled. 

Prepare  one  dozen  towels,  three  sheets,  two  pairs  very  long  stockings,  or  special  leggings, 
two  pillow-cases,  two  night-gowns,  two  physician's  gowns,  two  quart  Mason  jars  of  gauze  sponges, 
two  quart  Mason  jars  of  cotton  sponges,  two  pads  of  cotton  covered  with  gauze,  one  yard  square, 
one  receiver,  and  sufficient  vuh'ar  pads  and  umbilical  cord  dressings  for  the  mother  and  babe 
during  the  puerperium.  These  are  all  packed  in  appropriateh'  sized  bundles,  securely  covered 
A\'ith  towels  or  newspapers,  distinctly  labeled,  then  sterilized.  All  these  tilings  are  carefully  laid 
away,  protected  from  dust,  for  the  time  of  labor. 

Instruct  the  patient  how  to  determine  when  labor  is  at  hand,  and  what  to  do  imtil  j'ou  or 
the  doctor  arrives. 

DuRiXG  Labor. — When  you  are  called,  see  that  the  accoucheur  is  at  once  notified. 

See  that  there  is  a  supply  of  hot  and  cold  sterile  water. 

Prepare  the  patient  as  follows:  Give  colonic  flushing  of  warm  soapsuds;  shave  genitalia; 
full  shower-bath;  scrub  torso  with  soap  and  water,  pajing  special  attention  to  the  genitaha;  rinse 
and  wa.sh  thoroughlyfrom  ensiform  to  knees  "nith  1:1500  bichlorid.     Put  on  sterile  night-gown. 

Do  not  examine  the  patient  internally  nor  give  vaginal  douches  without  permission. 

Keep  an  accurate  record  of  pulse,  temperature,  and  all  the  o(;currences  during  labor  and  the 
puerperium. 

See  that  the  patient  takes  liglit  nourishment  during  the  first  stage. 

Provide  quiet,  cheer,  and  fresh  air  for  the  patient.     Allow  no  gossip. 

See  that  the  bladder  is  emptied  every  four  and  the  rectum  every  twelve  hours,  asking  the 
accoucheur  for  orders  regarding  them. 

When  the  second  stage  draws  near,  dress  the  bed  and  the  patient  with  the  sterile  articles. 

Be  ready  to  assist  the  accoucheur  in  caring  for  the  feces  wliich  may  escape  from  the  anus 
(basin  of  1:1.500  bichlorid  and  large  cotton  .sponges). 

Have  sterile  scis.sors,  tape,  and  artery  clamp  ready  for  the  cord,  and  gauze  pledgets  for  wiping 
the  eyehds  and  throat.     Antiseptic  f(jr  the  eyes. 

As  soon  as  the  child  is  severed,  wrap  it  warmly  in  the  receiver  and  put  in  a  warm,  safe  place. 
Look  at  it  occasionally  for  hemorrhage  from  tlie  cord  or  choking. 

Receive  the  placenta  in  a  l)asin  covered  with  a  sterile  towel,  and  bo  sure  to  present  it  to  the 
accoucheur  for  his  inspection. 

During  the  Pukupkhium. — Treat  the  genitalia  as  an  open  siji^ical  wound.  Change  the 
pads  when  soiled,  douching  the  external  genitals  with  1:3000  l)icfalorid  each  time.  Giye  no 
vaginal  douches  without  orders.     See  that  the  patient  urinates  witliijh  eight  hours  after  delivery. 

Give  her  one  ounce  of  castor  oil  on  the  morning  of  the  second  day  fitter  delivery.  Get  further 
instructions  from  the  accoucheur.

ANTENATAL  THERAPEUTICS 

Closely  allied  to  the  subject  of  eugenics  is  the  .special  care  of  the  woman  and 
her  babe  during  pregnancy,  with  a  view  of  producing  liealthy  and  mature  offspring. 
All  that  has  beeit  previously  said  in  this  chapter  really  has  this  t)bject:  but  if  one 
bends  his  mind  to  the  matter,  one  will  agree  with  Ballantyne  that  there  exi.sts 
here  a  field  .still  sparsely  .settled,  very  vast,  and  inteni^ely  alluring.  AVe  seek  to  tlis- 
cover  and  counteract  the  effects  on  the  fetus  of  syphilis,  tuberculosis,  hemophilia, 
alcoholism,  and  other  chemical  poi.sons,  lead,  arsenic,  phosphfjrus,  tobacco,  etc. 
We  .seek  to  discern  the  causes  of  abortion  and  premature  labor  and  to  avoid  them; 
also  to  learn  to  cure  those  diseases  which  necessitate  the  artificial  interruption  of 
pregnancy — for  example,  hyperemesis  gravidarum,  chorea,  placenta  pra'via,  etc. 
We  seek  to  trace  the  occurrence  of  fetal  monstrosities,  l)ut  have  not  advancetl  at  all 
in  this  direction,  even  in  the  ca.ses  of  those  women  who  have  such  a  hereditary  dis- 
position. 

In  practice  among  the  well-to-do  the  children  are  larger  and  stronger  than 
among  the  very  poor,  though  the  difference  is  not  as  great  as  one  would  ex]>ect. 
Studies  of  the  factory  workers  in  Europe,  where  the  proi)ortion  of  the  operatives 
that  are  jiregnant  women  is  larger  than  with  us.  have  provetl  that  their  chiklren  are 
more  likely  to  be  premature,  puny,  undersized,  or  weakly.  Certain  cities  have 
arranged  to  give  the  pregnant  woman  a  respite  from  work  for  six  weeks  before 
delivery  an<l  four  weeks  afterward,  and  France,  Italy,  and  Switzerland  are  consider- 
ing l)ills  making  such  relief  from  toil  obligatory.  Austria  and  (lermany  have  pa.'^.«*ed 
such  laws  and  have  rendered  their  apjilication  po.ssible  by  providing  the  financial 
aid  such  women  need  when  they  stop  working.  In  Paris  there  are  homes  for  women 
in  the  last  weeks  of  pregnancy,  and  experience  has  sho\Mi  their  good  effect  upon  the 
new-born  children  and  the  mothers.  But  our  maternities  should  do  this  and  more 
— they  should  !>(>  open  for  the  reception  of  ill  ])regnant  women,  or  those  with  ill 
fetuses,  with  a  view  of  the  thorough  scientific  study  and  investigation  of  the  di.^eascs 
of  gestation  and  of  the  unborn  fetus,  and  the  discovery  of  means  of  prevention,  cure, 
or  amelioration.     This  is  the  "prematernity  "  of  Ballantyne.

CHAPTER  XVIII 
THE  DIAGNOSIS  OF  PREGNANCY 

Certaixty  in  the  diagnosis  of  jiregnancy  cannot  always  ho  attained,  but  a  high 
degree  of  probability  can  be  reached.  This  most  common  condition,  which  any 
matron  thinks  she  could  diagnose  ^^dth  ease,  may,  after  skilful  application  of  all 
the  means  of  investigation,  assisted  by  long  experience,  and  studied  with  a  view  to 
careful  judgment,  escape  discovery  or  be  mistaken  for  something  entirely  different. 
While  we  Avill  admit  that  error  may  not  always  be  avoided,  it  is  also  true  that  l^lun- 
ders  are  more  often  due  to  carelessness  in  making  the  examination,  and  lack  of 
consideration  of  all  the  facts  learned  by  it,  than  to  ignorance.  Socrates  said  that 
in  studying  ourselves,  we  should  ''lay  aside  prejudice,  passion,  and  sloth,"  an  axiom 
which  could  well  apply  to  the  diagnosis  of  pregnancy. 

Sometimes  the  diagnosis  may  be  made  very  quickly,  but  the  accoucheur  is 
warned  to  guard  his  statements,  because  the  people  believe  the  fact  of  pregnancy 
should  be  very  patent  and  will  discredit  the  physician  if  the  event  prove  him  wrong, 
and,  further,  much  depends  on  his  decision.  The  question  of  heritage  of  property, 
of  prosecution  at  law  of  women  accused  of  crime,  of  an  illegitimate  conception, 
whereby  the  fair  name  of  a  woman  may  be  blasted,  of  legitimacy  of  offspring;  the 
proper  treatment  of  disease,  as  tuberculosis,  cancer — all  these  depend  on  the  cor- 
rectness of  his  opinion,  and  mistakes  are  very  disastrous  to  both  mother  and  child. 

The  difficulties  are  greater  in  the  first  four  months,  before  the  fetus  is  large 
enough  so  that  we  can  hear  it  or  feel  it,  but  sometimes  the  question  of  pregnancy  is 
unsettled  until  the  time  for  eventual  delivery. 

In  uncomplicated  cases,  where  only  the  question  of  pregnancy  arises,  the  pa- 
tient is  more  likely  to  be  pronounced  pregnant  when  really  not  so,  but  when  it  is  to 
be  determined  whether  pregnancy  complicates  some  other  pelvic  condition  or  simu- 
lates something  else,  the  pregnancy  is  more  apt  to  be  overlooked.  Thus  in  operat- 
ing for  fibroids  the  surgeon  is  occasionally  surprised  by  finding  a  pregnant  uterus. 

Sources  of  Error. — In  the  early  months  there  is  no  absolute  sign  of  pregnancy. 
The  character  of  a  gravid  uterus  can  be  perfectly  mimicked  by  several  other  condi- 
tions. In  the  later  months  the  positive  signs,  the  fetal  heart-tones  and  movements, 
may  be  absent,  the  child  being  dead  or  the  perception  of  the  movements  being 
interfered  with.  The  patient  herself  may  render  the  examination  nugatory;  she 
may  be  too  fat ;  have,  in  addition  to  pregnancy,  a  tumor,  ascites,  excessive  tympany, 
etc.,  or  she  may  hold  the  abdominal  walls  and  perineum  so  rigid  that  the  accoucheur 
can  feel  nothing  in  the  pelvis.  This  may  be  due  to  nervousness  or  tenderness  in 
the  belly,  or  it  may  be  practised  with  intention  to  deceive.  Another  source  of  error 
is  deliberate  falsifying  by  the  patient.  If  she  is  pregnant,  she  may  desire  to  conceal 
it,  in  order  to  get  the  accoucheur,  unwittingly,  to  produce  abortion,  either  with 
medicine  given  for  amenorrhea  or  by  passing  a  sound  into  the  uterus  for  diagnostic 
purposes.  When  not  gravid,  she  may  desire  a  positive  opinion  of  pregnancy  in 
order  to  perform  blackmail  or  institute  bastardy  proceedings,  or  to  acquire  an  estate, 
as  in  the  case  of  a  widow  being  left  property  on  the  birth  of  a  posthumous  child. 
Under  these  circumstances  she  will  declare  all  the  symptoms  of  pregnancy  to  exist, 
and  may  even  try  to  imitate  the  fetal  movements  ])y  contractions  of  the  abdominal 
walls.  On  the  other  hand,  the  accoucheur  cannot  always  accept  the  statements  of 
the  patient  as  true,  because  she  may  even  delude  herself  into  believing  she  is  preg- 

250 


THK    DIAGNOSIS   OF    PREGNANCY  251 

nant.  When  approachinp;  tlic  menopause,  especially  if  childless,  women  sometimes 
imagine  themselves  pregnant.  The  alxlomen  enlarges,  the  menses  cease,  they  feel 
the  movements  of  the  ehikl,  and  even  go  into  labor,  having  pains.  Pseudocyesis, 
spurious  pregnancy,  "grossesse  nerveuse,"  as  the  disease  is  called,  has  even  baffled 
the  diagnostic  ability  of  the  al)l('st  surgeons  and  accoucheurs. 

For  materials  on  which  to  build  a  diagnosis  of  pregnancy  we  must  review  those 
changes  of  the  maternal  organism  wrought  by  conception  which  were  considered 
in  the  Physiology  of  (lestation,  for  a  minute  study  of  which  the  reader  is  referred 
to  that  chapter.  As  in  the  discussion  of  a  disea.se,  we  divide  the  findings  into  two 
groups — first,  those  wliich  the  patient  tells  of,  called  "symptoms,"  and  tho.se  which 
the  examiner  himself  discovers,  called  "signs."  Symptoms  are  subjective  or 
rational.  Signs  are  objective  or  sensible.  In  general,  in  medicine,  it  is  wi.se  to  ad- 
here to  objectivity,  for  then  the  chances  of  error  are  reduced,  the  .suggestion  element 
of  the  pati(uit  being  removed.  Subj(>ctive  symptoms  have,  therefore,  little  value, 
and  an  opinion  based  on  them,  at  l)est,  is  presum]iti\('.  Objective  signs  have 
greater  value  and  may  allow  a  probable  or  unequivocal  oi)inion  of  pregnancy.  Mont- 
gomery suggested  such  a  division  of  the  proofs  of  pregnancy — presumptive,  probable, 
and  une(iuivocal.  It  is  wise  to  pursue  a  definite  scheme  in  eliciting  the  proofs  of 
pregnancy,  then  to  assign  to  each  one  its  proi)er  valuation,  and  to  compare  it  with 
the  sujij^osed  time  of  conception.  The  order  of  appearance  of  the  various  phenom- 
ena of  gestation,  their  mutual  relations  in  time  and  severity,  and  the  length  of 
their  existence — all  these  give  valuable  information  for  the  determination  of  jireg- 
nancy,  since  irregularities  from  the  tyj^ical  course  should  leatl  to  discovery  of  the 
causative  anomaly.  For  purpose  of  study  and  practice  the  pregnancy  is  divided 
into  three  periods  of  three  months  each,  that  is,  three  trimesters. 


FIRST  TRIMESTER— SUBJECTIVE  SYMPTOMS 
Cessation  of  Menstruation. — This  is  one  of  the  two  really  important  s^inptoms 
of  jiregnancy,  but  to  have  value  it  must  occur  in  a  woman  previously  regular — it 
must  persist  until  the  time  of  examination.  There  may  be  no  pathogenic  cause 
for  the  amenorrhea  and  no  disease  may  result  from  it.  Three  fallacies  untlerlie 
this  symptom: 

A.  Pregnancy  may  occur  without  menstruation:  (a)  As  in  a  girl  before  puberty; 
(6)  during  the  amenorrhea  of  lactation,  or  (c)  amenorrhea  from  other  causes,  as 
heart  (hsease,  tuberculosis,  and  from  no  cause  at  all;  (r/)  after  curetage;  (e) 
after  the  menopause.  Several  cases  are  on  record  where  a  woman  conceived  before 
the  menses  appeared,  conceived  again  during  the  amenorrhea  of  lactation,  and  thus 
the  reproductive  cycle  repeated  itself  several  times  without  the  appearance  of  the 
menses  for  years.  Cases  of  conception  occurring  during  lactation  are  so  frequent 
that  the  popular  idea  of  the  prevcMitive  effect  of  nursing  should  be  dropped.  Preg- 
nancies occurring  two,  even  four,  years  after  the  clinuicteric  have  been  reported. 

B.  Menstruation  may  continue  after  conception.  It  is  not  rare  to  learn  of  a 
woman  having  one  or  two  periods  after  she  is  surely  ])regnant,  but  usually  the 
amount  of  blood  is  small  and  the  character  of  the  flow  otherwi.se  abnormal.  If  the 
conception  occurred  just  l)efore  the  menses  were  due.  there  may  be  an  abortive  men- 
struation at  the  projier  time.  That  a  true  menstrual  How  could  occur  is  possible,  be- 
cause the  two  decidu£E  do  not  fuse  until  the  fifth  month.  Instances  where  a  normal 
menstruation  ]M^rsisted  during  tlie  nine  months  have  hvvn  re]iorted  by  Caruso  and 
Pettey.  The  older  writers  cite  ca.ses  where  the  jieriods  api>eared  only  during  preg- 
nancy. That  the  ovary  continues  to  functionate  during  gestation  is  highly  prol> 
able,  as  cases  of  superfetation  and  of  menstrual  molimina  aiul  autopsies  on  preg- 
nant women  prove.  It  is  wisest,  whenever  such  a  discharge  of  blood  occurs,  to 
consider  it  pathologic  and  to  investigate  carefully,  l)ecause  usually  one  of  the  follow- 


252  THE  HYGIENE  AND  CONDUCT  OF  PREGNANCY 

ing  conditions  is  causative:  al)ortion,  cervical  erosions,  disease  of  the  entlonietrimn, 
uterine  polyp,  fibroids,  rupture  of  a  varix  at  any  point  in  the  cervical,  vaginal,  vul- 
var canal,  extra-uterine  pregnancy,  diseases  of  the  ovum,  as  placenta  previa,  myxo- 
matous degeneration  of  the  chorion,  etc. 

C.  Other  conditions  may  cause  the  amenorrhea:  (a)  Change  of  climate  or 
environment,  noticeable,  for  example,  in  girls  coming  from  Europe.  It  seldom  per- 
sists over  three  months.  (6)  Mental  influence.  Fear  of  conception,  as  occurs  after 
illegitimate  exposure,  may  cause  the  menses  to  cease.  A  strong  emotion  may  do  the 
same,  (c)  Pathologic  conditions,  tuberculosis,  s\^3hilis,  anemia,  exposure  to  cold, 
and  local  tlisease,  atresia  of  the  h^^anen  or  the  vagina,  (d)  Some  women  are  habitu- 
ally irregular,  being  amenorrheic  for  several  months  at  a  time,  without  apparent 
cause  or  any  ill  health.  Occasionall}-  a  long  interval  will  interrupt  the  regular 
periods,  and  the  flow  is  likely  to  be  uncertain  during  lactation  and  the  approach  of 
the  menopause. 

One  is  reasonably  safe  in  regarding  a  woman  who  menstruates  perfectly  nor- 
mally as  not  pregnant,  and  also  one  who  can  conceive  and  is  otherwise  well,  and 
who  suddenly  ceases  to  flow,  as  presumably  with  child. 

The  value  of  this  symptom  is,  therefore,  only  presumptive,  but  it  is  useful  in 
fixing  the  date  of  conception  and  to  determine  the  time  of  labor,  and  must  alwa^'s  be 
noted  for  this  ])ur])ose. 

The  Morning  Sickness,  or  Nausea  and  Vomiting. — Among  the  so-called 
sympathetic  symptoms,  a  tendency  to  nausea,  often  with  vomiting,  occurring  in  the 
early  morning,  must  first  be  mentioned. 

This  usually  begins  after  the  fourth  week,  but  may  show  itself  earlier,  as  in  a 
case  quoted  by  Montgomery,  where,  at  the  end  of  the  week  after  marriage,  the 
patient  felt  squeamish.  If  the  nausea  is  limited  to  a  certain  period  of  the  day, 
mostly  the  morning,  is  not  attended  with  symptoms  of  disease,  comes  on  in  a  woman 
who  can  conceive  and  who  previously  was  well,  it  is  highly  presumptive  of  the  be- 
ginning of  pregnancy. 

About  one-third  of  gravidse  have  nausea  and  vomiting  as  a  marked  symptom; 
one-third  complain  of  it  occasionally  or  as  being  inconsiderable,  and  about  one-third 
are  free  from  them  entirely.  The  nausea  and  vomiting  occur  earlier,  more  constantly, 
and  more  severely  in  primiparse  than  in  multiparse.  They  recur  in  succeeding  preg- 
nancies, though  usually  in  lighter  form.  Women  of  nervous,  high-strung  tempera- 
ments suffer  more  than  those  of  the  lower  and  hard-working  classes.  This  symptom 
is  further  of  value  in  that  its  continuance  renders  probable  the  life  of  the  fetus,  it 
having  been  observed  that  when  the  child  dies  the  vomiting  ceases.  As  we  shall 
see  when  we  come  to  discuss  the  pathology  of  pregnancy,  the  nausea  and  vomiting 
are  probably  of  a  toxemic  nature.  By  the  time  of  quickening  the  stomach  is  usually 
settled.  The  value  of  this  symptom  is  only  presumptive,  because  there  are  so  many 
other  causes  for  stomach  disturbances.  It  seems  that  many  irritations  in  the  pelvis, 
tumors,  pelvic  peritonitis,  salpingitis,  and  appendicitis,  may  cause  them. 

Salivation. — A  slight  increase  of  saliva  is  a  not  infrequent  accompaniment  of 
the  nausea,  and  has  the  same  cause,  probably  a  toxemia.  Dewees  called  it  "cotton 
spitting,"  and,  occurring  in  a  healthy  woman,  unattended  with  foetor  ex  ore  or  other 
sign  of  mercurialization,  it  has  some  slight  value  in  the  diagnosis  of  pregnancy, 
though  it  may  occur  in  other  uterine  conditions  and  hysteria.  There  is  a  gingivitis 
which  occurs  at  this  period,  with  salivation,  loosening  of  the  teeth,  bleeding  from 
the  gums,  etc.,  which  is  distinctlypathologic,  and  will  be  considered  in  the  Pathology 
of  Pregnancy,  as  also  will  the  profuse  salivation,  an  exaggeration  of  the  above 
sjanptom. 

Change  in  disposition,  the  feeling  of  1)eing  pregnant,  various  neuralgias,  and 
other  subjective  symptoms  are  unreliable  in  a  serious  diagnosis,  because  they  can 
all  be  auto-suggested  by  the  patient,  especially  if  she  is  yearning  for  a  child.     How-

ever,  wlifii  an  intclligont  multipara,  having  missed  a  period,  believes  she  is  prog- 
nuiit,  DIM'  iimst  attach  at  least  ijrcsuinptive  vahic  to  the  symptom. 

Irritability  of  the  Bladder  and  Symptoms  of  Pelvic  Congestion.—  The  pregnant 
uterus  does  not  weigh  heavily  on  the  bladder  because  its  specific  gravity  is  about 
the  same  as  that  of  the  intestines,  but  the  anteversion  of  the  fundus  throws  the  cervix 
toward  the  hollow  of  the  saerum  and  stretches  the  ba.se  of  the  bladder,  causing  the 
freciuenoy  of  urination  so  often  mentioned  by  gravidic  in  the  first  trimester.  Later, 
when  the  fundus  comes  to  be  supported  by  the  abtlominal  wall,  the  cause  and  the 
symptom  disappear.  The  softening  of  the  parts  and  the  congestion  of  the  jx-lvis 
lead  to  a  leukorrhea  of  which  the  patient  com])lains  only  if  there  was  previously  some 
catarrh  of  the  organs,  which  catarrh  is  usually  much  aggravated  by  the  pregnancy. 
Tile  value  of  these  two  symjjtoms  is  obviously  only  j^resumptive. 

The  tingling  and  even  shooting  j)ains  in  the  t)reasts,  with  Iheir  enlargement, 
also  serve  to  draw  the  physician's  attention  1o  the  jjossibility  of  pregnancy. 


OBJECTIVE  SIGNS— FIP  ST  TRIMESTER 

The  Breasts. — As  early  as  the  fourth  week  there  may  be  some  enlargement  of 
the  breasts,  and  often  the  patient  notices  a  tingling  or  burning  sensation  in  them. 
The  enlargement  i)rogresses  from  periphery  to  center,  and  c(jntinues  througluMit 
])regnancy,  though  not  evenly.  Linea'  albicantes  or  stria?  gravidarum  ai)i)ear  on 
them,  and  blue  veins  may  be  seen  coursing  under  the  thin  skin,  especially  near  the 
nipple.  The  nlpjile  tlarkens  and  becomes  more  sensitive  and  erectile;  the  primary 
areola  darkens  and  becomes  i)uiTy,  as  if  there  were  air  under  the  skin.  One  nuty 
sometimes  feel  the  sinuses  lactiferi  in  the  areola.  The  tubercles  of  Montgomery 
enlarge,  and  occasionally,  even  in  the  first  trimester,  on  pressure,  a  fine  stream  of 
colostrum  may  be  expressed  from  them.  They  may  connect  with  the  sinuses  lac- 
tiferi. These  tubercles  not  seldom  become  infected  during  pregnancy  or  the  puer- 
periuni.  Around  the  areola,  es])eciaily  in  brunets,  there  often  develops  another 
pigmented  area — the  secondary  areola.  It  is  lighter  in  shade  than  the  ]iigmenta- 
tion  of  the  primary  areola,  and  resembles  dusty  paper  on  which  water  has  been 
sprinkled,  an  eff(H't  due  to  the  absence  of  coloring  around  the  sweat-glands.  The 
nipple  and  prinuu-y  areola  are  often  covered  with  branny  scales,  ma(U' up  of  dried 
sei)aceous  matter  and  ejiithelium.  The  epithelium  of  the  areola  sometimes  ex- 
foliates, carrying  the  i:)igment  with  it,  showing  that  the  latter  is  deposited  in  the 
deeper  epidermal  layers.  Much  of  the  coloring  disappears  after  weaning  of  the 
baby,  but,  especially  in  brunets,  more  or  less  remains  permancnitly. 

Colostrum  may  be  (>xi)ressed  from  tlie  ni])i)le  as  (>arly  as  the  twelfth  week,  but 
it  may  not  be  present  until  after  deliv(>ry.  ( )f  these  hndings,  the  most  signihcant  is 
the  change  in  the  areola,  the  tleeixMied  color,  and  the  puffiness.  All  the  signs  are 
mor(>  marked  in  primipara^,  as  in  multipara?  traces  often  hold  over  from  jm'vious 
l^regnancies.  The  l)reast  signs  have  no  value  in  an  old  multijxira  as  the  brea.-^ts 
are  enlarged  and  often  contain  milk  for  years.  Aside  from  these  fallacies— (1) 
neurotic  women  may  have  tingling  in  the  brea.sts,  enlargement  of  the  areola,  and 
even  colostrum  during  the  menstrual  periods,  (2)  Cases  of  pseudocyesis  may  show 
all  the  signs.  (3)  Prostitutes  and  masturbators  not  seldom  show  the  signs,  es- 
pecially if  they  have  pelvic  disease.  (4)  The  l>rea.st  changes  have  be«>n  ob.served  in 
cas(>s  of  ovarian  cyst,  fibroids,  hematometra.  It  nuist  be  admitted  that  under  these 
circumstances  the  findings  are  not  so  tyi^cal,  but  their  occurrence  in  other  con- 
ditioiis  than  of  pregnancy  lowers  the  value  of  the  sign.  Especially  is  the  jiresence  of 
colostrum  d(>ceptive.  It  occurs  in  neurotic  women,  even  if  unmarried,  and  in  men. 
and  the  lower  animals  not  pregnant.  Cases  are  on  record  where  girls  have  suckled 
infants,  the  brea.st  lieing  stinuilated  by  irritating  iK)ultices  and  suction,  and  men 
have  nursed  chiUlren  (Tanner).     The  value  of  this  sign,  therefore,  is  presumptive,

THE  HYGIENE  AND  CONDUCT  OF  PREGNANCY 


and,  if  the  changes  are  all  marked  and  typical,  which  usually  occurs  about  the  fifth 
month,  the  pregnancy  might  be  said  to  be  proba])I(\  Init  at  this  time  there  are  other 
certain  signs. 

It  serves  to  call  attention  to  the  necessity  of  a  ])elvic  examination.  During 
lactation  a  sudden  diminution  of  the  quantity  and  alteration  of  the  quality  of  the 
milk,  which  usually  produce  effects  on  the  nursling,  are  suggestive  of  the  existence 
of  a  new  })regnancy. 

Bluish  Discoloration  of  the  Vulva,  Vestibule,  and  Vagina.^Jacquemin,  in  183G, 
discovered  this  bluish,  dusky  hue  of  the  vestibule  and  anterior  wall  of  the  vagina, 
but  Chadmck,  in  188G,  emphasized  its  importance.  The  sign  is  named  after  both 
these  men.  It  is  usually  most  marked  around  the  meatus  and  in  the  vestibule, 
extending  up  the  anterior  vaginal  wall,  and  is  likened  to  the  color  of  the  lees  of  wine 


Fig.  287. — Hegak's  Sign.     Usual  Method. 


— that  is,  an  opaque,  bluish  tint  with  a  tendency  to  violet.  It  appears  about  the 
eighth  to  the  twelfth  week,  and  becomes  more  marked  as  pregnancy  advances.  It 
is  more  marked  in  multipara;  than  in  primiparse,  in  women  with  catarrhal  or  other 
cUsease  of  the  genitalia,  and  in  those  with  contracted  pelvis,  especially  if  they  have 
had  previous  hard  deliveries.  It  is  almost  always  present,  but  may  not  appear  until 
very  late,  and  in  rare  cases  not  at  all.  It  often  disappears  if  abortion,  with  hemor- 
rhage, begins  and  if  the  ovum  is  blighted.  Since  the  discoloration  is  essentially  a 
local  venous  congestion,  it  may  be  simulated  by  other  conditions  which  may  cause 
the  latter — for  example,  menstruation,  rapidly  growing  pelvic  tumors  of  all  kinds, 
displacements  of  the  uterus,  residua  of  previous  pelvic  inflammation  which  disturb 
the  pelvic  circulatory  conditions  (parametritis,  scars,  phle])itis,  thrombosis),  and  in 
heart  disease  and  obesity.     All  these  circumstances  detract  from  the  value  of  the 


THE   DIAGNOSIS   OF   PREGNANCY

sign,  leaving  it  only  presumptive.  Attempts  have  been  made  to  diagnose  pregnancy 
with  the  cystoscope,  and  when  all  the  other  pelvic  organs  show  the  non-inflammatory 
congestion  of  ijrcgiiancy,  the  Madder  siiows  it  also. 

Softening  of  the  Cervix  and  Vagina.— The  congestive  hyi>ereniia  of  the  jielvis 
is  early  niauilcsted  by  a  .sollcning  ol  the  vagina  and  the  cervix.  These  may  be 
noted  in  primipara)  in  the  sixth  week,  and  even  earlier,  by  an  acute  observer,  in 
multiparie.  The  upi)er  and  lower  portions  of  the  cervix  soften  first,  and  at  the  same 
time  one  notes  the  succulence  of  the  vagina,  with  an  increase  of  tiie  leukorrheal  dis- 
charge. Goodell  ascribed  much  diagnostic  value  to  this  sign,  saying:  "  If  the  cervix 
feels  as  hard  as  the  cartilage  of  the  nose,  no  pregnancy  exists;  if  it  feels  like  the 
mucous  membrane  of  the  lip,  pregnancy  is  possible."  The  same  fallacies  underlie 
this  sign  as  the  last,  and  its  value,  therefore,  is  only  presumptive.  P'urther,  in  ca.ses 
of  ciu-onic  cervicitis  the  cervix  may  soften  but  little  until  the  last  months  of 
pregnancy. 

Hegar's  sign,  or  softening  and  comjiressibiiity  of  the  istluuus  uteri  and  l(jwer

uterine  segment  (Fig.  287).  On  bimanual  examination  the  isthmus  uteri  is  com- 
pressed between  the  two  fing(>rs  in  the  posterior  forni.x  and  the  abdominal  iiand.  In 
typical  cases  one  can  bring  the  fingers  together  so  that  the  uterine  tissue  between 
seems  reduced  to  the  thinness  of  paper.  In  fat  women,  or  those  in  whom  the  al>- 
dominal  muscles  are  held  rigid,  one  nuiy  elicit  the  sign  with  one  finger  in  the  rectum 
and  the  tiunnb  in  the  vagina  (Fig.  288).  It  may  be  necessary  to  give  ether  and  to 
draw  the  uterus  down  with  a  vulsellum  to  get  the  infornuition.  l>ut  ca.><es  are  rare 
where  such  a  procedure  is  indispensable.  This  sign  is  only  another  evidence  of  the 
softening  of  the  uterine  muscle.  The  succulence  of  the  tissues  is  most  marked  in 
the  lower  uterine  segment  and  ujiper  cervix  (the  istlnnus'),  and  ]iermits  the  pressure, 
exerted  by  tiie  fingers,  to  displace  tiie  ovum  toward  the  fundus  uteri  anil  tt)  slide 
the  various  muscular  lamelUr  away.  In  some  favorable  ca.ses  the  muscle  is  so  soft 
that  it  can  be  raised  in  a  fold  or  ridge.  Hegar's  sign  ajipears  in  multipara?  at  the 
sixth  week,  and  in  primipane  at  the  eighth  week,  but  is  seldom  fully  developed 
until  the  t(>nth  week,  disaj^pearing  when  tiie  uterus  attains  a  size  and  height  which 
make  the  part  inaccessil)le. 


256  THE  HYGIENE  AND  CONDUCT  OF  PREGNANCY 

"VVTien  well  marked  and  typical,  the  sign  is  highly  presumptive  and  one  of  the 
most  reliable  of  the  first  trimester,  hut  that  is  all.  The  author  has  found  the  isthmus 
uteri  soft  and  compressible  in  many  cases  months  after  an  abortion  or  laljor,  in 
congested  uteri,  chronic  pelvic  peritonitis,  and  occasionally  just  before  and  during 
menstruation.  The  findings  may  be  imitated  by  a  retroflexed  uterus,  the  angle  of 
fiexion  being  soft,  and  by  a  fil^roid  in  the  uterine  wall.  Indeed,  the  isthmus  uvdy  be 
so  softened  and  elongated  that  the  cervix  has  l)een  held  for  the  whole  non-pregnant 
uterus  and  the  pregnant  fundus  has  been  tliagnosed  as  a  tumor  of  the  ut(n"us  or 
adnexa.  On  the  other  hand,  even  in  pregnancy,  the  sign  may  be  absent  or  very 
slightly  marked,  or,  oA^'ing  to  fat  or  rigidity  of  the  parts,  it  cannot  be  elicited. 

Changes  in  Form,  Size,  Consistence,  and  Position  of  the  Uterus.— These  have 
been  descril^ed  in  the  Physiology  of  Pregnancy  and  Local  Changes  (p.  77). 

(a)  Form. — The  change  from  the  thin  pear  shape  of  the  \argin  uterus  to  the 
rounded,  plump,  bulbous  form,  is  very  noticeable.  If  the  ovum  nests  very  near  to 
the  entrance  of  one  tube,  that  half  of  the  uterus  will  develop  first  and  give  the  fundus 
great  asymmetry,  and  it  might  lead  to  a  false  diagnosis  of  extra-uterine  or  cornual 
pregnancy  (Fig.  347) .  (See  Ectopic  Pregnancy.)  It  is  called  "  grossesse  angulaire  " 
by  the  French.  In  the  later  development  of  the  ovum  the  symmetry  is  reestab- 
lished. Early  in  pregnancy  one  lateral  half  is  thicker  than  the  other,  or  either  the 
anterior  or  the  posterior  wall  of  the  uterus  is  bulged  outward  more,  these  variations 
being  due  to  the  location  of  the  ovum.  Toward  the  end  of  this  trimester  the  bulg- 
ing of  the  fundus  at  the  sides,  above  the  relatively  small  cervix,  may  he  appreciated 
by  the  finger  placed  in  the  lateral  fornices. 

(6)  Size. — Every  enlargement  of  the  uterus  gives  rise  to  the  suspicion  of  preg- 
nancy, and  steady  increase  in  size  is  one  of  the  most  valuable  signs  we  have,  but  at 
least  two  examinations  are  required,  and  the  examiner  must  be  capable  and  careful. 
The  same  rate  of  growth  is  found  with  no  other  uterine  tumor.  A  phenomenon 
that  has  not  been  explained  is  a  sudden  softening  and  enlargement  of  the  uterus, 
sometimes  asymmetric,  followed,  after  a  short  period,  by  a  return  to  the  original 
conditions.  It  easily  leads  to  errors  in  diagnosis.  If  a  uterus  that  has  shown  the 
usual  gradual  enlargement  of  pregnancy  suddenly  begins  to  grow  too  fast,  one  will 
suspect  a  polyh^'dramnion  or  hydatid  mole;  if  the  growth  is  interrupted  and  reces- 
sion begins,  a  blighted  ovum.  The  accoucheur  carefully  notes  the  size  of  the  uterus 
at  his  first  examination.  Four  weeks  later  he  examines  again,  and  if  the  uterine 
tvmior  corresponds  in  size  to  that  expected  for  pregnancy,  such  a  diagnosis  is  always 
certain.     Hematometra  and  fibroids  do  not  grow  like  this. 

(c)  Consistence. — An  experienced  hand  can  very  often  make  a  diagnosis  of 
early  pregnancy  from  this  one  sign.  A  pregnant  uterus  is  elastic,  spongy,  and  soft, 
resembling  dough.  At  the  site  of  the  ovum  the  corpus  is  a  little  softer  than  the 
empty  part  of  the  uterus,  while  between  lies  a  groove  which  is  quite  soft.  This  last 
phenomenon  is  not  constant  and  hard  to  elicit,  and  the  conditions  must  be  un- 
usually favorable  (Fig.  95).  Braxton  Hicks  called  attention  to  the  intermittent 
uterine  contractions  of  later  pregnancy.  The  author  has  felt  the  uterus  contract 
as  earl}^  as  the  eighth  week,  and  it  may  even  contract  in  spots.  This  sign  ma}'  be 
used  for  diagnosis  (Dickinson). 

(d)  Position. — The  strong  anteversio-flexio  of  the  uterus,  lying  like  a  lump  of 
dough  upon  the  bladder,  serves  to  draw  the  attention  to  a  possible  pregnancy  im- 
mediateh'  on  the  introduction  of  the;  finger  into  the  vagina. 

These  four  signs,  taken  together,  and  l)y  an  experienced  examiner,  arc  suffi- 
cient to  make  a  highly  probable  diagnosis  of  pregnancy. 

General  Considerations. — The  examination  should  be  conducted  systemati- 
cally, all  tlie  points  being  elicited,  not  being  satisfied  with  one  or  two.  The  bowels 
and  bladder  should  he  eni]:»ti('(l,  all  constriction  of  the  abdomen  removed,  with  the 
patient  lying,  appropriately  draped  and  at  ease,  on  a  table.     If  a  definite  order  is 


tup:  diagnosis  of  pregnancy  257 

followed,  none  of  the  signs  will  bo  overlooked,  and  the  accoucheur  will  be  spared  the 
mortifying  necessity  of  reciuesting  the  patient  to  go  back  on  the  table  for  reexamina- 
tion. It  need  not  be  said  that  the  usual  antiseptic  precautions  are  to  be  followed. 
Since  a  positive  diagnosis  in  the  first  trimester  may  be  made  im\y  under  most  favor- 
able circumstances,  the  accoucheur  should  leave  the  answer  doubtful,  rather  than 
to  announce  a  probable  condition  as  certain,  and  request  the  patient  to  return  in 
four  weeks.  In  cases  where  the  reputation  of  the  woman  is  concerned  it  is  best  to 
wait  until  the  jwsitive  signs  of  the  second  trimester  are  present.  If  the  examiner 
suspects  that  the  woman  desires  a  diagnosis  with  a  view  of  going  to  an  abortionist 
for  criminal  purposes,  he  should  withhold  it  entirely  for  several  months,  as  the  pul)lic 
believes  abortion  is  safe  only  in  the  earliest  weeks.  Under  no  circumstances  may  a 
physician  prescribe  a  placebo  to  satisfy  the  woman's  desire  for  an  abortifacient. 

The  biologic  diagnosis  of  pregnancy  has  been  made  jjossible  by  Abderhalden,' 
and  promises  to  be  of  permanent  value.  It  depends  on  the  determination  of  a 
ferment  in  the  blood  of  pregnant  women,  which  will  reduce  placenta-albumen.

CHAPTER  XIX 
SYMPTOMS  AND  SIGNS  OF  THE  SECOND  AND  THIRD  TRIMESTERS 

During  the  second  three  months  of  pregnancy  there  is  usually  a  subsidence  of 
the  s^nnptoms  called  sympathetic, — the  nausea  and  vomiting,  salivation,  neuralgias, 
and  the  irritability  of  the  bladder, — with  an  increase  of  the  mechanical  s^anptoms. 
Menstruation  is  still  absent,  and  a  new  subjective  sjonptom  develops — the  patient 
feels  the  motion  of  the  child. 

Quickening. — About  the  sixteenth  to  the  eighteenth  week  the  woman  begins 
to  feel  something  in  the  abdomen,  entirely  unlike  any  previous  sensation.  It  is 
said  to  resemble  the  fluttering  of  a  tiny  bird  in  the  hand.  It  usually  takes  her  a 
week  to  determine  what  it  is,  and  finally  she  concludes  it  is  the  movement  of  the 
child  within  her.  She  is  usually  beset  with  various  emotions,  especially  if  this  be 
her  nature,  and  immediately  feels  the  full  glory  of  maternity.  "Quickening"  is 
the  term  applied  to  the  first  perception  of  the  active  fetal  movements,  and  is  a  relic 
of  the  barbarous  time  when  the  ovum  was  considered  inanimate  until  it  was  felt. 
The  law  reflected  this  belief  and,  until  recently,  a  woman  could  be  hanged  for  murder 
if  she  had  not  "felt  life,"  or  "quickened,"  and  the  innocent  babe  thus  executed  too. 

Fetal  movements  are  felt  earlier  by  women  who  have  felt  them  before,  and  thus 
have  learned  to  recognize  the  faint  impulses,  and  cases  are  recorded  of  "  feelinglife" 
at  ten  weeks  after  conception.  The  motions  may  not  be  sensible  until  the  sixth  or 
seventh  month,  and  in  rare  instances  not  at  all  throughout  pregnancy.  The  author 
had  one  such  case  where,  in  two  pregnancies,  the  child  was  never  felt  and  was  born 
well  at  term.  The  movements,  which  are  weak  at  first  and  later  stronger,  may  be 
so  vigorous  that  the  patient's  rest  is  disturbed,  or  ihey  may  be  very  sluggish  through- 
out pregnancy.  Rest,  warmth,  and  narcotics  diminish  the  motion;  their  opposites 
increase  them.  A  shock,  physical  or  mental,  may  abolish  the  movements  for  a  time, 
even  if  the  child  is  well.  The  motion  may  also  cease,  without  cause,  for  periods  of 
daj'S  or  weeks.  Hunger  and  fever  at  first  stimulate  the  fetus;  later,  paralyze  it. 
As  a  symptom  of  pregnancy,  the  quickening  is  of  but  presumptive  value,  because  the 
mother,  if  she  desires  offspring,  only  too  easily  imagines  the  sensation.  Fetal  move- 
ments are  declared  in  nearly  every  case  of  pseudocyesis.  IVIontgomery  refers  to  the 
famous  case  of  Queen  Mary,  whose  disappointment  on  learning  that  her  fancied 
fetal  movements  were  only  the  signs  of  a  Ijeginning  dropsy,  caused  her  to  instigate 
terrible  persecutions  of  the  Protestants.  Active  intestinal  peristalsis  gives  the 
patient  the  impression  of  the  movements  of  a  child,  as  also  may  contraction  of  the 
recti  muscles,  a  tumor  in  the  belly  falling  from  side  to  side,  and  contractions  of 
portions  or  all  of  the  uterine  wall  when  there  is  a  fetus,  but  it  is  dead. 

One  may  use  the  symptom  for  diagnosis  in  intelligent  Avomen  who  are  without 
motive  for  deception.  It  may  serve  as  a  sort  of  check  on  the  date  of  the  last  menses, 
in  determining  the  length  of  pregnancy.  In  primipara3,  count  twenty-two  weeks 
ahead  to  find  the  probable  date  of  confinement;  in  a  nuiltipara,  twenty-four  weeks. 

OBJECTIVE  SIGNS— SECOND  TRIMESTER 
Owing  to  the  presence  of  positive  signs,  the  diagnosis  of  pregnancy  may  be 
affirmed  during  this  trimester.     Although  some  authors  assert  that  conditions  exist 
where  one  must  wait  until  the  physiologic  end  of  gestation  arrives  for  a  sure  diagnosis, 
the  writer  has  never  met  such  a  case. 

258 


SYMPTOMS   AND    SIGNS   OF   THE   SECOND    AND   THIRD    TRIMESTERS  259 

The  Intermittent  Uterine  Contractions.— Braxton  Hicks  first  descrilx?d  them, 
and  tlicy  arc  sonu'tiincs  niiuicd  after  him.  As  early  as  tlie  tentli  week  the  whole 
uterus  can  he  felt  to  contract,  assuming  more  of  a  pear  shap<.'  and  then  relaxing, 
without  any  perception  by  the  mother.  The  contractions  recur  at  very  irregular 
intervals — minutes  or  hours  and  perhaps  days.  Parts  of  the  uterine  muscle  may 
also  contract  and  confuse  the  diagnosis.  A  cold  hand,  brusk  manipulation,  the 
active  movementsof  the  child  (B.  Hicks),  bring  on  the  contractions,  and  toward  the 
end  of  pregnancy,  or  when  premature  labor  is  threatening,  the  irritability  of  the 
uterus  is  such  that  even  orilinary  palpation  causes  the  uterus  to  harden.  Nor- 
mally not  felt  by  the  mother,  they  may  be  present  in  the  latt(T  weeks  and  disturb 
her  rest  seriously  as  "false  pains."  These  produce  no  dilatation  of  the  cervix,  and 
thus  are  distinguished  from  true  labor  pains.  A  neurotic  temperament  usually 
explains  the  phenomenon.  It  is  claimed  that  the  virgin  uterus  contracts,  and  we 
know  that  a  non-pregnant  uterus  can  expel  blood-clots,  membranes,  and  fibroid 
tumors.  The  contractions  of  i)regnancy,  therefore,  are  only  the  evidence  of  an 
exaggcTated  normal  functi(jn  of  the  uterine  unstriped  muscular  fibcTS.  The  inter- 
mittent ut(Tine  contractions  have  the  action  of  a  local  heart,  squeezing  the 
blood  out  of  the  sinuses  and  allowing  the  influx  of  new  blood  in  diastole;  second,  the 
pelvic  tissues  and  cervix  are  softened  by  the  local  hyperemia  produced,  and  the  so- 
called  "vital  dilatation"  is  favored;  third,  the  regular  a.ssumption  of  the  uterus 
of  its  proper  pear  form  causes  the  fetus  to  take,  and  keep,  a  position  favorable 
to  lab(jr. 

Soft  fibroids  and  hematometra  may  cause  the  uterus  to  contract,  but  not  in 
tjT^ical  fashion,  and  the  recti  muscles  sometimes  imitate  the  sign;  but  with  these 
eliminated,  the  intermittent  uterine  contractions  become  positive  evidence  of 
pregnancy,  and  are  found  irrespective  of  the  life  or  death  of  the  fetus. 

Active  fetal  movements  felt,  seen,  or  heard  by  the  obstetrician  are  a  certain 
sign  of  i^regnancy,  and,  in  favoral)le  cases,  the  observer  being  skilled,  may  be  de- 
termined as  early  as  the  twelfth  week  (Pinard).  One  may  see  the  slight  shock  of 
the  abdominal  wall,  or  the  passage  of  a  limb  under  it,  and  sometiuK^s  the  motions 
are  so  vigorous  that  they  are  visible  through  the  clothes,  much  to  the  embarrassment 
of  the  mother.  With  the  stethoscope,  one  hears  a  light  tap,  like  that  of  the  fingr-r 
against  the  back  of  the  hand,  held  with  its  palm  against  the  ear.  With  the  hand 
laid  on  the  belly,  one  ]>erceives  a  weak  knock,  or  stroke,  i)ut  sometimes  C|uite  tumul- 
tuous actions  of  the  extremities  and  back.  Fetal  hiccuj)  has  already  been  referred 
to.  Active  intestinal  peristalsis  bears  some  resemblance  to  this  motion,  as  do  also 
partial  uterine  contractions, and, remarkable  as  it  may  seem,  these  movements  have 
l)een  imitated  by  tlie  abdominal  muscles,  so  tiuit  even  painstaking  examiners  have 
been  misled.  The  famous  case  of  Joanna  Southcott,  the  false  prophetess,  who 
thus  carried  on  an  imposture  for  years,  is  one  in  point.  Eliminating  these  sources 
of  error, — and  this  is  very  easy, — the  sign  is  a  positive  one  of  pregnancy  and  of  the 
life  of  the  child. 

Passive  Fetal  Movements. — Owing  to  the  flaccidity  of  the  uterine  wall  and  the 
amount  of  rKpior  amnii.  we  can  give  certain  movements  to  thi'  fetus  which  have  lu'iMi 
called  " ballot tement "  or  ''repercussion."  The  sign  is  best  elicited  with  the  patient 
in  position  for  the  usual  gATiecologic  examination.  Two  fingers  in  the  vagina  give 
the  body,f(>lt  just  above  the  cervix, a  gentle  j^ush;  the  alulominal  hand  feels  it  strike 
th(>  fundus  of  the  uterus,  ami  the  fingcTS  feel  it  come  to  rest  again  on  the  cervix. 
This  is  typical  ballottement  and  is  very  rarely  thus  ol)tained,  one  usually  feeling  the 
body  leave  and  return  to  the  fingers  in  the  vagina.  RejX'rcussion  is  found  from  the 
sixteenth  to  the  thirty-second  week.  Before  this  time  the  fetus  is  too  small  and 
after  it  too  large,  with  too  little  liquor  amnii,  but  one  may  obtain  partial  ballotte- 
ment of  the  head  by  means  of  the  abdominal  examination,  especially  in  l)reech  ca.ses. 
Another  method  of  obtaining  the  sign  is  to  place  the  woman  at  tlie  edge  of  the  bed 


260  THE    HYGIENE    AND    CONDUCT    OF    PREGNANCY 

on  her  side,  allowing  the  uterine  tumor  to  hang  over.  A  stroke  on  the  uterus  from 
below  is  now  given — a  very  uncertain  procedure. 

Ballottement  may  be  simulated  by  an  anteverted  uterus  floating  in  ascitic  fluid, 
a  fibroid  or  ovarian  tumor  with  long  pedicle  in  the  same,  and  a  stone  in  the  bladder. 
It.  therefore,  l^ecomes  a  positive  sign  of  pregnancy  only  when  these  three  are  ex- 
cluded. 

Direct  Palpation  of  the  Fetal  Body. — This  sign  depends  entirely  on  the  skill  of 
the  observer.  On  palpating  an  enlarged  uterus  one  will  feel  a  hard  body  with  parts 
which  resemble  the  head  or  extremities  of  a  fetus,  but  one  must  avoid  hasty  con- 
clusions. 

Fetal  parts  may  be  discovered  as  early  as  the  fourth  month,  and  as  the  child 
grows  more  and  more,  can  be  differentiated,  so  that  later  we  can  distinguish  "large 
parts " — head  and  breech — and  "small  parts " — the  extremities.  Lumps  of  feces  in 
the  sigmoid,  carcinoma  of  the  peritoneum,  sarcoma  of  the  ovaries,  tumors  of  the 
omentum,  fibroids  of  the  uterus,  can  all  assume  shapes  and  positions  which  would 
mislead  a  careless  observer.  The  absence  of  fetal  parts,  in  a  case  of  pregnancy  where 
they  should  be  felt,  will  lead  to  the  suspicion  of  a  blighted  ovum  or  polyhydramnion. 

Auscultatory  Signs. — The  Fetal  Heart-tones. — Mayor,  of  Geneva,  in  1818, 
described  the  fetal  heart-tones,  but  it  is  believed  (Fasbender)  that  they  were  first 
heard  by  Philip  le  Goust,  in  1650.  Lejumeau  de  Kergaradec,  in  1822,  published  a 
monogTaph  on  the  sul)ject  which  is  classic,  and  but  little  has  been  added  to  our 
knowledge  since.  Both  observers  were  listening  to  discover  the  sounds  made  by  the 
fetus  splasliing  in  the  liquor  amnii.  Depaul  heard  the  heart-tones  as  earl}^  as  the 
eleventh  week,  but  usually  one  finds  them  first  in  the  fifth  month  of  gestation, 
though  it  often  requires  close  application  and  favorable  external  conditions,  even 
at  this  tune.  At  first  faint,  the  beat  becomes  stronger  as  the  child  grows  larger. 
Wlien  nearer  to  the  abdominal  wall,  the  sound  is  heard  better,  also  through  a  thin 
wall,  and  when  the  baby's  back  is  directed  anteriorly.  A  large  amount  of  liquor 
amnii,  the  placenta  lying  in  front,  the  uterine  bruit,  rumbling  gas  in  the  bowels,  and 
external  noise  all  easily  extinguish  the  sound. 

The  fetal  heart-tones  resemble  the  tick-tack  of  a  watch  heard  by  the  ear 
through  a  pillow;  tick — short  pause,  tack — long  pause.  The  first  sound  is 
isochronous  with  the  systole  of  the  heart  and  with  the  pulse  in  the  umbilical 
arteries;   the  second  sound  is  due  to  the  closure  of  the  semilunar  valves. 

The  rapidity  of  the  beat  normally  varies  from  120  to  160  per  minute,  the  usual 
range  being  132  to  144.  Mention  has  been  made  of  the  supposed  influence  of  sex, 
and  ex]Derience  does  seem  to  show  that  girls'  hearts  beat  faster  than  boys',  but  the 
knowledge  is  of  little  value  in  practice.  Marked  variations  in  rapidity  of  the  heart- 
beat occur  ^vithout  cause,  the  count  running  up  to  180  even,  and  then  subsiding. 
Fetal  movements  accelerate  the  beat;  palpation  of  the  fetal  body  does  the  same. 
Fever,  fasting,  asphyxia,  and  hemorrhage  increase  the  rapidity  of  the  heart. 
Uterine  contraction,  pressure  on  the  fetal  brain,  slow  it. 

Pestalozza  obtained  a  cardigram  of  the  fetal  heart,  and  the  writer  has  felt 
it  beat  through  the  abdominal  wall  in  a  case  of  face  presentation,  an  experience 
reported  by  others  also. 

Methods  of  E. r  mm  no  Hon. —Th(?  naked  ear,  the  monaural  stothosrope,  and  the  binaural 
stethoscope  all  give  good  results.  One  will  use  the  ear  when  witliout  an  instrument,  and  in  places 
where  rumbling  exterior  noises  interfere,  but  it  is  disagreeable  to  patient  and  examiner.  A  con- 
strained yjosition  should  be  avoided,  because  this  produces  circulatoiy  noises  in  the  middle  ear, 
and  a  smooth  towel  must  always  b(>  laid  between  the  ear  and  the  skin. 

Tiie  monaural  stethoscope  (Fig.  289)  made  of  metal  is  very  useful,  because  it  can  be 
easily  sterilized  (as  with  the  instruments  before  an  operation),  and  pressure  toward  the  fetus 
may  be  made  with  it  by  the  h(>ad,  thus  diminishing  the  thickness  of  the  intervening  structures. 
Best  of  all  is  the  binaural  stethoscope  with  a  large  t)ell.  This  should  be  made  all  of  metal  and 
rubber,  so  that  it  may  be  boiled  with  the  instruments  for  ol)stetric  operations.  During  ausculta- 
tion, nothing  may  touch  the  instnunent  save  the  skin  of  tlu^  patient  and  the  ear  of  the  examiner. 
Pressure  \\ith  the  fingers  causes  a  faiut  hum,  wliich  often  completely  covers  the  sounds.     To

The  fetal  heart -tones  arc  the  iiKJst  reUable  sign  we  have  for  the  diagnosis  of 
pregnancy.  Unless  the  mother's  heart-beat  is  transmitted  to  tlie  lower  al>d(jmen

existence  of  a  cliild  in  the  belly.  By  feelin<;  the  mother's  pn\sv  while  listening 
over  the  uterus,  and  noting  the  ditference,  72  and  140,  and  by  following  the  line  of 
increasing  intensity  of  the  sounds,  the  sign  is  easily  proved. 

The  Fetal  Souffle. — This  is  sometimes  called  the  funic  souffle,  a  name  given  t<i  it 
by  its  discoverer,  Evory  Kemiedy.  in  1833.  It  is  due  to  the  rush  of  blood  through 
the  umbilical  arteries,  and  is  heard  when  they  are  subject  to  j)re.'<sure  or  torsion 
or  tension,  for  example,  coiling  of  the  cord  around  the  neck,  cord  too  short,  betwi'cn 
the  back  of  child  and  abdominal  wall,  and  under  compression  by  the  stethoscojie. 
In  thin  women  the  writer  has  felt  the  cord  coursing  over  the  fetal  back.  In  fetal 
heart  disease  one  hears  cardiac  murnuirs  with  the  usual  fetal  heart-tones.  These 
nun-inurs  may  disappear  after  delivery,  or,  if  the  disease  is  organic,  be  permanent. 

The  fetal  soufHe  is  a  soft,  l)lowing  nuirmur  heard  with  the  first  sound,  but  it

may  he  with  both,  or  even  diastoUc.  It  occurs  in  al)()ut  15  per  cent,  of  pregnant 
women,  being  more  common  during  labor.  When  present,  this  sign  is  diagnostic 
of  pregnancy. 

The  Uterine  Souffle. — Kergaradec,  in  his  paper  (1822),  described  a  sound  which 
he  heard  while  listening  at  the  sides  of  the  uterus,  and  he  ascribed  it  to  the  rushing  of 
blood  through  the  placenta,  caUing  it  the  "placental  souffle."  It  is  a  soft,  blowing 
sound,  synchronous  with  the  maternal  heart,  having  a  rushing  character,  similar 
to  the  bruit  heard  in  an  aneurysm  or  in  the  veins  of  the  neck,  or  like  the  French 
"vous,"  pronounced  in  a  low,  blowing  tone — "voo."  During  uterine  contraction 
it  is  diminished  or  altered  in  quality;   sometimes  both. 

It  is  heard  best  at  the  left  side  of  the  uterus,  low  down,  but  may  be  heard  on 
the  right  side  or  anteriorly — occasionally  all  over  the  uterus,  or  on  both  sides. 

It  may  be  loud,  drowning  the  fetal  heart-tones,  or  soft,  hardly  audible — even 
absent  in  some  (10  per  cent.)  cases.  It  may  be  heard  at  one  time  and  be  absent 
in  the  same  place  later.     It  may  disappear  during  the  examination. 

In  character  it  is  humming,  blowing,  rushing,  sibilant,  or  even  musical.  It 
may  be  continuous  or  intermittent  or  wavy.  It  is  without  shock,  and  is  usually 
single,  but  may  be  both  systolic  and  diastolic.  Sometimes  pressure  with  the  stetho- 
scope intensifies  the  sound  and  alters  its  character,  and  one  may  feel  the  rush  of 
the  blood  at  the  side  of  the  uterus  wdth  the  fingers  as  a  systolic,  fine  vibrant  thriU. 
The  origin  of  the  sound  is  in  the  large  vessels, — arteries  and  veins  in  the  sides  of 
the  uterus, — and  its  similarity  to  the  sound  of  a  varicose  aneurysm  is  striking. 
It  is  not  in  the  placenta  because  it  has  been  heard  after  the  placenta  is  removed, 
and  at  locations  far  from  the  placental  site.  It  seems  loudest  near  the  placental 
site.  There  is  no  sound  by  which  we  can  locate  the  placenta,  though  in  extra- 
uterine pregnancy  a  marked  uterine  souffle  will  serve  to  indicate  the  location  of 
the  ovum  in  the  belly.  The  sound  does  not  come  from  compression  of  the  iHac 
arteries  by  the  uterus,  because  it  is  heard  vnih  the  patient  in  the  knee-chest  posi- 
tion and  before  the  uterus  has  a  chance  to  compress  them. 

Depaul  has  discovered  the  uterine  souffle  as  early  as  the  twelfth  week,  but  most 
observers  have  not  heard  it  until  the  sixteenth  week.  It  is  found  whether  the  fetus 
is  alive  or  dead,  but  usually  diminished  in  the  latter  case. 

As  a  diagnostic  sign  of  pregnancy  its  value  is  only  probable,  because  it  is 
heard  over  all  rapidly  growing  tumors — fibroids,  ovarian  cysts,  even  in  enlarged 
spleen  and  liver,  and  in  cases  of  anemia  and  maternal  heart  disease,  the  cardiac 
murmurs  being  transmitted. 

Changes  in  Form,  Size,  Consistence,  and  Position  of  the  Uterus. — These  have 
already  been  considered  under  the  Physiology  of  Pregnancy.  In  the  diagnosis  of 
pregnancy  the  shape  of  the  uterine  tumor,  its  size  for  the  supposed  length  of 
gestation,  the  consistence  and  location — all  these  are  hardly  imitated  by  any  other 
condition :  the  practised  hand,  with  one  grasp,  can  usually  get  enough  information 
for  a  decision.  Any  doubt  will  be  set  at  rest  by  determining  the  rate  of  growth  of 
the  uterus,  when  examined  at  intervals  of  two  to  four  weeks.  No  other  tumor 
grows  so  rapidly  nor  so  typically.  A  peculiar  phenomenon  that  is  as  yet  unex- 
plained, and  which  may  confuse  the  diagnosis,  is  a  sudden  enlargement  of  the  uterus 
to  the  size  of  one  several  months  longer  pregnant,  and  then,  as  sudden,  a  subsidence 
to  the  natural  size.  It  is  referred  to  by  Buettner  and  Dickinson.  In  the  author's 
case  it  very  materially  complicated  the  diagnosis.  Should  the  uterus  cease  grow- 
ing uniformly,  or  even  get  smaller,  the  ovum  is  probably  blighted. 

These  signs,  together,  give  us  positive  information  of  pregnancy. 

Changes  in  the  Skin. — Pigmentation;  the  mask  of  pregnancy;  the  striae 
gravidarum;  the  changes  in  the  navel — at  first  retracted,  then  pouting,  then  drawn 
up;  the  varicose  veins — all  these  are  significant,  but  have  little  real  diagnostic 
value. 


SYMPTOMS   AND    SIGN'S    OF   THE    SECOND    AND    THIRD    TRIMESTERS  263 

O'Donnoll,  of  Chicago,  in  1911,  demonstrated  an  x-ray  picture  of  a  woman 
six  months  pregnant.  It  is  reproduced  herewith.  Mention  must  be  made  of 
the  .serodiagnosis  of  pregnancy  by  means  (jf  the  epiphanin  and  other  reactions.

SYMPTOMS  AND  SIGNS  OF  THE  THIRD  TRIMESTER 

The  menses  continue  al)sent.  Any  l)loody  siiow  now  is  eitlier  pathologic  or 
means  that  hd)or  is  beginning.  Tlie  morning  siekne.<;s  is  usually  ab.sent.  Its 
persistence  or  reajipearaiice  indicates  the  necessity  for  a  careful  examination  of 
stomach,  liver,  ami  kidneys.  Rarely,  the  vomiting  is  the  result  of  crami)ing  of  the 
stomach  by  the  high  uterus.  Active  fetal  movements  are  a  more  pronounced 
symptom,  and  may  harass  the  mother,  but  the  child  usually  quiets  down  as  labor 
b(>coines  imminent. 

I.  The  painless  uterine  contractions  become  more  and  more  noticeable  as  the 
months  go  bv,  until,  toward  the  end  of  this  trimester,  the  uterus  often  responds  to 


264  THE  HYGIENE  AND  CONDUCT  OF  PREGNANCY 

very  slight  irritants.     In  this  way  the  cervix  antl  pelvic  structures  are  prepared 
for  the  great  dilatation  they  are  al)out  to  undergo. 

2.  The  examiner  now  has  no  troulile  to  find  the  movements  of  the  cliild. 

3.  Ballottement,  or  repercussion,  is  not  obtainable,  unless  there  is  a  great 
deal  of  liquor  amnii  (polyhydramnion),  but  partial  repercussion  is  easily  elicited, 
especially  in  breech  presentations. 

4.  Direct  palpation  of  the  fetal  body  is  plain,  and  toward  the  end  of  the  tri- 
mester is  the  same  as  during  labor.  One  may  now  diagnose  the  presentation  and 
position. 

5.  The  fetal  heart -tones  are  louder  and  more  constant,  and  one  is  more  likely 
to  hear  the  funic  souffle  and  active  fetal  movements. 

6.  The  uterine  bruit  is  more  intense  and  more  distributed. 

7.  The  changes  in  form,  size,  consistence,  and  position  of  the  uterus  are  very 
marked.     These  have  already  been  discussed.     (See  p.  83.) 

8.  The  .r-ray  will  ahvays  disclose  the  fetal  skeleton. 

Only  gross  carelessness  will  explain  a  mistake  in  the  diagnosis  of  pregnancy 
during  this  trimester.  Excessive  fat  in  the  abdominal  wall,  the  presence  of  tumors, 
anasarca,  and  general  peritonitis,  in  the  author's  experience,  have  caused  much 
difficulty,  but  have  not  rendered  a  working  decision  impossible.

Rarely  it  is  impossible  to  make  a  positive  diagnosis  at  the  end  of  the  sixth 
month  of  gestation.  In  the  third  trimester  all  the  signs  become  more  apparent 
and  more  convincing. 

The  Diagnosis  of  Lightening. — When  the  woman  notes,  toward  the  end  of 
pregnancy,  a  subsidence  of  the  symptoms  referable  to  the  upper  alxlomen  and  an 
increase  of  pelvic  symptoms,  and  at  the  same  time  a  change  in  the  configuration 
of  the  b(>lly,  as  is  described  on  p.  86,  it  is  fair  to  assume  that  lightening  has 
occurred. 

If,  on  examination,  one  finds  the  anteversion  of  the  uterus  increased,- — the 
plateau-like  fundus,  the  head  deep  in  the  inlet, — and  on  internal  exi)loration  the 
changes  described  and  illustrated  on  p.  88,  the  diagnosis  is  positive.  A  real 
prognostic  value  attaches  to  this  phenomenon.     It  means  that  the  particular  head 


SYMPTOMS    AND    SIGNS    OF   THP:    SECOND    AND    THIRD    TRIMESTERS  265 

can  pass  the  i)articular  pelvic  inlet,  and  since  the  majority  of  serious  pelvic  de- 
fonnities  are  at  tiie  inlet,  it  j)re(licts  a  successful  delivery.  Linhteninp;  may  be 
absent  in  the  following  conditi(jns:  Contracted  pelvis  and  its  complement— a  large 
fetus;  twin  pregnancy;  polyhydramuion ;  multiparity;  occipitoposterior  posi- 
tions; presence  of  the  placenta  in  the  lower  uterine  segment  (|)lacenta  previa); 
tumors  blocking  the  inlet.  In  priniipara'  the  al)sence  of  lightening  is  v(Ty  signifi- 
cant. 

Diagnosis  of  the  Life  and  Death  of  the  Fetus. — Without  j)ositive  evidence  to 
the  contrary,  a  fetus  is  considered  alive.  While  we  can  easily  a.s.sert  that  the  child 
lives,  we  can  less  readily  bo  sure  that  it  is  dead.  Tlie  heart -tones,  the  fetal  souffle, 
and  active  fetal  movements  determined  l)y  the  accoucheur  are  convincing  that 
the  fetus  lives.  In  a  woman  who  is  healthy  and  feels  perfectly  well  it  is  usually 
safe  to  assume  that  the  child  is  living. 

Symptoms  and  Signs  of  Fetal  Death. — 1.  Cessation  of  fetal  movements  after 
they  have  been  felt.     Presum])tive. 

2.  Languor,  malaise,  ligiit  ciiilliness,  foul  taste  in  the  mouth,  symptoms  which 
arc  due  to  the  absorption  of  toxins  from  the  dead  fetus  and  are  analogous  to  those 
arising  from  degenerating  fibroitls,  are  presumptive  symptoms  only.  The  same  is 
to  be  said  of  the  feeling  of  weight,  or  of  a  body  lying  heavily  in  the  abdomen. 
Sudden  cessation  of  the  nausea  and  vomiting,  in  the  early  months,  is  suggestive  of 
fetal  death. 

3.  If  a  w'oman  gives  a  history  of  losing  several  children  at  a  certain  month  in 
pregnancy  and  now  has  identical  symptoms,  the  information  is  suggestive,  ^^'hen  a 
cau.se  exists  for  anticipating  fetal  death,  the  diagnosis  is  rendered  ea.sier.  Such 
conditions  are  syjihilis,  eclampsia,  nephritis,  high  fever,  cholera,  etc. 

4.  Absence  of  heart-tones.  This  sign  is  of  value  only  after  repeated,  j^ro- 
longed  examinations,  under  most  favorable  conditions  (quiet  room,  proper  posi- 
tion, etc.),  have  failed  to  find  the  heart-tones. 

5.  Cessation  of  growth  of  the  uterus  and  alxlominal  tumor.  A  valuable  sign 
if  controlled  by  examinations  repeated  every  three  weeks.  The  uterus,  insteatl  of 
growing,  gets  smaller,  harder,  and  usually  more  evenly  resistant  all  over;  though, 
occasionally,  it  l)ecomes  irregular,  and  then  making  the  distinction  from  a  fibroid 
is  very  difficult.  The  intermittent  ut(Tine  contractions  an^  more  marked  and  there 
may  be  an  occasional  discharge  of  bloody  or  brownish  muc-us.  Unless  carefully 
coasidered,  this  sign  may  be  fallacious,  because,  sometimes,  the  uterus  apjiarently 
ceases  to  grow  or  even  grows  smaller  for  a  time,  even  with  a  li\'ing  chikl  (one  of 
the  causes  of  placenta  circumvallata),  and,  again,  the  uterus  may  enlarge  after  the 
tleath  of  the  ovum,  as  in  hydatidiform  mole. 

().  The  only  positive  sign  of  fetal  death  is  the  palpation  of  the  softened  and 
macerated  fetal  head,  with  the  bones  freely  movable  on  each  other,  the  scalp 
hanging  like  a  loose  sac.  This  sign  may  be  elicited  through  the  vault  of  the  vagina, 
through  the  cervical  canal,  or,  rarely,  through  the  abdominal  wall.  Maceration  of 
the  fetus  is  usually  so  far  advanced  in  a  week  to  ten  days  that  the  softening  of 
the  skull  may  be  discovered.  On  abdominal  examination  the  uterus  and  fetus  do 
not  have  the  characteristic  feeling  of  elasticity  and  firmness,  but  this  sign  i.s  hard 
to  elicit  and  is  valuable  only  to  an  experienced  accoucheur. 

7.  The  discharge  of  bloody  licjuor  anmii  or  milky  fluid  is  suggestive,  but  one 
must  eliminate  liNdrorrhd'a  gravidarum  and  early  rupture  of  the  anmion  with  .^ub- 
chorionic  development  of  the  ovum. 

8.  The  breasts  cease  to  grow,  becoming  flabby  and  pendent.     Presumptive. 

9.  The  patient  lo.ses  weight,  which  is  significant,  because  she  ought  to  gain  in 
the  last  four  months.

266  THE  HYGIENE  AND  CONDUCT  OF  PREGNANCY 

It  is  not  absolutely  necessary  to  make  a  positive  diagnosis,  since,  if  the  fetus  is 
dead,  delivery  ^vill  soon  occur.  (See  Missed  Abortion,  Chap.  XXXII.)  It  is  usu- 
ally not  necessary  to  induce  labor,  because  no  harm  results,  except  in  the  rarest 
instances.  The  woman  is  instructed  not  to  have  intercourse,  to  take  no  douches, 
etc.,  and  to  report  any  imusual  symptoms. 

Diagnosis  of  Multiparity. — It  sometimes  becomes  necessary,  especially  in 
medicolegal  cases,  to  determine  if  an  existing  pregnancy  is  the  first  one,  or  if  a 
woman  has  previously  borne  a  child.  Such  a  diagnosis  can  usually  be  made  if 
sufficient  care  be  used,  but  if  more  than  five  years  have  elapsed  since  the  birth  of  the 
last  child,  if  it  was  small  or  prematurely  born,  if  it  was  removed  b}'  a  crushing  opera- 
tion or  by  a  cesarean  section,  or  if  the  genitalia  be  ver^'  large,  it  ma}'  be  impossible 
to  come  to  a  positive  decision,  because  the  only  signs  we  have  are  the  relics  of  the 
traumatisms  of  labor. 

1.  The  deep  rupture  of  the  hjTnen  and  perineum.  If  the  perineum  is  torn 
and  the  patient  avers  that  no  operation  on  it  had  been  performed  and  that  she  never 
suffered  local  injur}-  or  had  an  ulcerous  disease,  the  sign  is  positive.  If  the  patient 
wishes  to  hide  the  previous  pregnancy,  she  may  claim  to  have  suffered  injury  in 
some  way.  Rupture  of  the  hymen  alone  is  not  so  certain  a  sign,  since  it  almost 
alwaj's  tears  during  coitus.  Deep  tears,  forming  later  the  carunculse  myrtiformes, 
occur  only  during  labor  or  the  delivery  of  a  large  body,  as  a  fibroid.  The  hjTnen 
may  be  congenitally  absent,  or  it  may  be  so  distensible  that  it  does  not  rupture 
during  delivery.  The  author  saw  only  one  such  case,  with  a  syphilitic  fetus  weighing 
three  pounds. 

2.  Deep  tears  and  scars  in  the  cervix.  In  primiparse  the  cer\4x  is  conic, 
with  a  round  os.  In  multiparse,  owing  to  ine"\atable  greater  or  less  laceration,  the 
portio  vaginalis  is  more  cylindric  or  knob-shaped,  and  the  os  is  a  transverse  slit. 
Even  if  the  laceration  of  the  cervix  is  only  moderate,  one  can  distinguish  two  lips — 
an  anterior  and  a  posterior.  Scars  in  the  cervix  may  result  from  operation,  ulcera- 
tion, and  disease,  congenital  or  acquired.  Prolapsus  uteri  and  eversio  cervicis 
have  been  found  in  infants;  and  chronic  cer\dcitis,  in  virgins,  may  cause  changes 
Avhich  imitate  a  parous  cervix. 

3.  Vaginal  scars  are  often  the  result  of  labor,  but  the}-  ma}'  be  due  to  opera- 
tion, injury,  or  ulcerative  process,  which  not  infrequently  complicates  the  acute 
infectious  diseases,  e.  g.,  measles  and  scarlatina.  The  vagina  of  a  nullipara  is 
rugous,  rough,  and  tight,  the  levator  ani  holcUng  it  well  up  against  the  pubic  arch. 
In  a  multipara  the  reverse  is  true,  but  if  many  years  have  elapsed  since  child- 
birth, a  great  deal  of  the  original  condition  is  reestablished.  The  laceration  of  the 
urogenital  septum  and  of  the  anterior  strands  of  the  levator  ani  is  one  of  the  most 
constant  of  puerperal  injuries. 

4.  The  breasts  are  more  pendulous,  flabby,  with  deeply  pigmented  areolae, 
and  sometimes  colostrum  may  be  expressed  from  the  nipples.  The  fallacies  under- 
lying this  sign  have  already  been  mentioned. 

5.  Striae  gravidarum  may  be  found  on  the  breasts,  abdomen,  and  thighs — 
old,  white,  crinkled,  and  silvery,  mixed  with  the  pinkish  or  purplish  lines  of  a  new 
pregnancy.  Striae  are  found  in  fat  people,  in  girls  as  they  round  out  at  puberty,  in 
some  cases  of  abdominal  tumors,  after  typhoid  fever;  and,  further,  they  are  absent 
in  5  per  cent,  to  10  per  cent,  of  prt^gnancy  cases. 

0.  The  recti  and  abdominal  muscles  are  usually  relaxed  and  stretched  after 
the  woman  has  had  a  full-term  child,  but  the  author  has  seen  several  women  in 
whom  the  abdominal  figure  was  perfect  after  two  or  three  full-term  deliveries. 

In  medicolegal  cases,  therefore,  one  can  seldom  assert  positively  that  preg- 
nancy has,  or  has  not,  taken  place.  Aljortions  and  premature  labor  leave  still 
fewer  traces  behind  them,  and  in  such  instances  the  medical  witness  must  exer- 
cise still  greater  caution. 


SYMPTOMS   AND    SKINS    OF   THE   SECOND    AND   THIUD    TUIMESTERS 


267 


The  Diagnosis  of  the  Time  of  Pregnancy  and  the  Prediction  of  the  Day  of 
Confinement.  Both  physician  and  i)atii'iit  desire  to  know  when  labor  will  occur. 
One  nwiy  wish  to  induce  labor  for  contracted  pelvis  or  to  jjrevent  overgrowth  of 
the  child;  the  other  wishes  to  know  so  that  she  may  arrant*'  her  household  affairs, 
enf!;;i}i;e  the  nurse,  and  st)  forth,  hence  it  is  a  matter  of  some  moment  to  l)e  able  to 
disct)ver  the  exact  day,  or  come  near  it.  Since  the  real  duration  of  i)reKnancy  is 
unknown,  we  can  never  be  sure  of  the  day  when  labor  is  to  be^in.  The  moment  of 
conception  vari(\s,  labor  is  more  or  less  accidental,  and,  finally,  the  leuRth  of  preg- 
nancy varies  in  ditTerent  women  and  in  the  same  woman  in  her  succeeding  preg- 
nancies.     (See  p.  2(».  The  Duration  of  Pregnancy.) 

Dctcrniindtion  from  l)(it(i  (iitrn  hi/  the  Paliint. —  1.  The  date  of  the  fruitful 
coition.  No  reliance  is  to  be  placed  on  the  statement  of  the  patient  that  the 
fruitful  coition  is  distinguished  by  a  peculiar  sensation,  and.  tiierefore.  may  be  used 
in  the  reckoning.  The  date  of  a  single  coitus  is  more  rclial)le.  and  this  may  be 
known,  as  in  cases  of  sudden  death  or  absence  ot"  husliand.  rape,  etc    If  the  monthly

period,  due  within  a  lew  tlays  of  this  date,  remains  absent,  the  probability  that 
conci'ptiou  oi-curnul  about  this  time  is  very  strong.  One  should  count  27.'i  days  from 
the  date  t)f  the  single  coitus  to  di>termine  the  date  of  contineinent.  In  about  one- 
half  of  the  cases  this  dat(>  will  l)e  right  within  seven  <lays. 

2.  The  hist  menstruation.  Xaegele's  rule  is  to  count  l)ack  three  months  from, 
ai\d  add  seven  days  to.  the  date  of  the  first  day  of  the  hust  men.struation;  for  cx- 
ami)lt>,  if  the  pati(>nt  menstruated  last  beginning  March  1st.  December  St h  will  lx» 
the  day  of  labor.  In  about  til)  per  cent,  of  cases  this  metlnxl  is  correct  within  eight 
days. 

3.  Quickening.  It  is  customary  to  count  ahead  twenty-ft>ur  weeks  in  multi- 
pani>  and  twenty-two  weeks  in  priniipara^:  but  in  view  of  what  was  said  regarding 
this  .symptom,  it  is  |)lain  that  no  reliance  at  all  is  t(»  be  plac«>d  on  the  data  ol)tained.

2.  The  determination  of  the  size  of  the  fetus  gives  more  certain  information, 
as  from  this  we  may  guess,  A^ith  a  fair  amount  of  accuracy,  its  age.  Direct  mea- 
surement of  the  length  of  the  fetus  in  the  uterus,  as  practised  by  Ahlfeld  (Fig.  292), 
is  possible,  and,  since  the  length  of  the  child  is  our  best  (but  poor  at  that)  guide  to  its 
age.  we  frequently  make  use  of  this  method.  In  primiparse  one  branch  of  the 
pelvimeter  (sterilized)  is  placed  against  the  head  from  the  vagina,  the  other  branch 
resting  on  the  breech.  In  multiparse,  since  the  head  usually  does  not  enter  the  pel- 
vis until  labor  has  begun,  one  puts  the  first  l)rancli  of  the  pelvimeter  over  the  upper 
border  of  the  pubic  symphj'sis.     By  doubling  the  figure  obtained  and  subtracting 


Fig.  293. — Using  Ferret's  Cephalometer. 
Any  pelvimeter  may  be  used  as  well.     Photograph  at  Chicago  Lying-in  Hospital. 


2  cm.  for  the  thickness  of  the  soft  parts,  one  arri\-es  at  the  length  of  the  fetus  and 
from  this  may  deduce  the  period  of  the  pregnancy. 

Direct  measurement  of  the  fetal  head  has  been  practised,  and  Perret  has  in- 
vented a  cephalometer  for  the  purpose  (Fig.  293).  Such  an  instrimient  is  entirely 
unnecessary,  the  ordinary  pelvimeter  giving  equally  good  results.  One  first  care- 
fully determines  the  position  of  the  head  with  reference  to  the  pelvis,  and  then 
places  the  branches  of  the  pelvimeter  as  nearl}'  as  possiljle  in  the  occipitofrontal 
diameter.  One  to  two  centimeters  must  be  deducted  from  an  ol)lique  measure- 
ment to  obtain  the  biparietal  diameter,  and  another  centimeter  for  the  thickness  of 
the  abdominal  w^all.  Surprisingly  accurate  results  are  obtained,  and  the  value  of 
the  procedure  increases  with  experience.  In  breech  and  shoulder  presentation  the 
head  is  easil}^  measured,  unless  labor  has  })egun,  but  when  the  head  has  engaged,  it' 
can  no  longer  ])e  properly  grasped;  then,  however,  the  measurement  is  not  needed.

prcf^nancy,  83^2  t"i>i.,  al)out  tliirty-ftjur  weeks,  and  1)3  2  ^''"-  ii'"JUt  forty  weeks. 

TIk!  nieasureinent  of  the  fetal  head  is  especially  desirable  in  ca.ses  of  contracted 
pelvis,  where  the  question  of  the  induction  of  premature  labor  arises,  or  of  a  radical 
operation  at  the  time  of  full-term  lalxjr. 

'.i.  Direct  i)alpati()n  of  the  fetal  btjdy.  Loii^  experience  will  enable  the  prac- 
titioner to  guess  quite  accurately  the  size  and  weight  of  the  child  in  utero,  but  even 
if  his  guess  is  correct,  the  information  is  of  little  value,  because  children  may  vary 
so  much  in  size  even  at  identical  periods  of  pregnancy.  The  authcjr  delivered,  on 
the  same  day,  a  child  at  the  eighth  month  of  i)regnancy  which  weighed  eight  pounds, 
and  another,  where  the  mother  was  three  weeks  beyond  lier  reckoning,  which 
weighed  three  and  one-half  pounds.  It  has  also  seemed  that  the  child  has  periods 
of  slower  ami  quicker  growth,  similar  to  those  of  its  extra-uterine  existence.  Again, 
the  child  may  have  a  large  head  and  a  small  trunk,  or  vice  versa.  It  is  clear,  there- 
fore, that  all  estimations  of  the  i)eri(j(l  of  j^regnancy  and  of  the  ])r<)bable  date  of 
confinement,  based  on  the  size  of  the  fetus,  are  unreliable. 

4.  Lightening  before  labor.  It  is  quite  safe  to  expect  the  delivery  to  occur 
within  three  weeks  from  the  time  the  head  settles  into  the  pelvis.  Often  this  oc- 
currence is  attended  by  regular  uterine  contractions  which  may  sinmlat«'  the  real 
pains  of  delivery.  Schatz  has  sought  to  determine  the  time  of  labor  by  a  study  of 
the  periodicity  of  the  false  pains  of  the  latter  months  of  pregnancy,  and  by  deduc- 
tions from  a  study  of  the  variations  in  the  maternal  blood-pressure.  It  has  been 
found  that,  during  pregnancy,  daily  examinations  of  the  blood-pressure  show  regular 
phases  which  seem  to  have  two  types,- — a  twenty-one-day  and  a  twenty-eight-day 
type,  similar  to  the  usual  menstrual  periodicity.  The  false  pains  of  pregnancy 
seem  to  occur  at  the  period  of  the  curve  where  the  blood-pressure  is  highest,  and  it 
has  been  noted,  too,  that  labor  occurs  at  these  periods.  A  determination,  witli  the 
sphygmomanometer,  of  the  blood-pressure  type,  in  the  latter  months  of  pregnancy, 
therefore,  might  give  some  hint  as  to  the  day  on  which  labor  might  l)e  expected. 

5,  The  changes  in  the  lower  uterine  segment  and  cervix,  as  described  in  the 
physiology  of  pregnancy,  give  only  relatively  valuable  information  of  the  proximity 
of  labor,  because  they  have  been  observed  three  to  six  weeks  before  deliAery,  and 
may  remain  absent  until  actual  pains  have  lieen  in  ojieration  some  time.  The  ex- 
tnMw;  sensitiveness  of  the  uterus  to  external  irritation  may  give  a  hint  as  to  the 
nearness  of  labor.

CHAPTER  XX 

THE  CONDUCT  OF  LABOR 

It  is  a  great  satisfaction  to  the  accoucheur  to  go  to  the  home  of  the  parturient 
knowdng  that  everything  for  the  proper  conduct  of  labor  has  been  provided  and  is 
in  readiness.  This  sense  of  satisfaction  is  enhanced  if  he  has  with  him  a  case  or 
satchel  containing  all  the  instruments  and  apparatus,  dressings,  and  medicines 
necessary  for  the  usual  case  of  labor  and  for  the  most  common  complications. 
What  the  accoucheur  will  carry  in  his  obstetric  satchel  will  depend  on  the  condi- 
tions of  his  practice  and  individual  preference.  If  his  patients  are  on  distant  farms, 
he  should  take  with  him  a  complete  obstetric  armamentarium,  which,  though  heavy 


Fig.  29-i. — Autuok's  Obstetric  Satchel.     White  Suit  and  Stethoscope  Taken  Out. 


and  bulky,  is  necessary  if  he  would  give  them  all  the  benefits  of  his  art.  For  a 
to^\Ti  or  city  practice,  the  instruments  for  the  rarer  operations — craniotomy,  liebos- 
teotomy,  etc. — need  not  always  be  carried.  It  is  absolutely  essential  that  the 
physician  be  prepared  for  the  operations  of  perineorrhaphy,  forceps,  and  version, 
and  for  the  complications,  postpartum  hemorrhage  and  asphyxia  neonatorum. 
The  author's  satchel,  for  ordinary  labor  cases,  contains  the  articles  on  the  list  sub- 
joined. For  complicated  cases  a  separate  bag,  containing  everything  for  operations 
from  perineorrhaphy  to  cesarean  section,  is  provided.  It  weighs  50  pounds  and 
is  very  bulky,  but  when  the  parturient  cannot  be  taken  to  the  hospital  operating- 
room,  the  operating-room  must  be  taken  to  the  parturient.

272  THE    HYGIENE   AND    CONDUCT   OF    LABOR 

Basins  and  towels  are  to  be  found  at  the  patient's  house.  If  they  are  not, 
three  one-quart  cream  pans  and  a  package  of  six  sterile  towels  must  be  added  to 
the  above  outfit.  All  these  tilings  can  be  comfortably  packed  into  a  17-inch 
"cabin"  satchel.  The  instruments,  all  but  the  scissors  and  stethoscope,  are 
packed  in  the  pan,  and  are  boiled  in  the  same  just  before  they  are  used.  The  medi- 
cine bottles  are  held  in  two  bags  made  of  ordinary  white  cotton  duck,  washaljle. 
Objection  has  been  made  to  the  leather  satchel  on  the  score  of  its  becoming  infected. 
This  is  possible  if  the  physician  is  careless  and  allows  it  to  become  soiled  with  blood, 
etc.  No  contrivance  can  be  invented  to  take  the  place  of  an  aseptic  conscience. 
B}'  exercising  care  that  the  satchel  is  not  soiled,  by  frequently  cleaning  it  with  a 
cloth  dampened  in  alcohol,  it  may  be  kept  in  a  safe  condition.  The  instruments  are 
boiled  before  using,  and  the  aseptic  articles  are  all  in  hermeticallj'  sealed  bottles. 
WTien  the  satchel  has  been  exposed  to  a  knowm  infected  case,  a  half-ounce  of  forma- 
lin poured  on  a  towel  laid  among  the  bottles,  with  the  lids  closed  for  a  few  hours,

The  methods  for  the  sterilization  and  preparation  of  gloves,  gauze,  etc.,  will 
be  found  in  the  Appendix. 

The  Question  of  Assistance. — A  distinction  between  hospital  and  home 
practice  in  obstetrics  is  gradually  creeping  into  our  scientific  discussions.  Careful 
study  of  existing  conditions  will  convince  any  one  that  the  safest  place  for  the 
parturient  woman  is  the  special,  well-equipped  Ijdng-in  hospital.  Here  are  all 
the  facilities  for  the  aseptic  conduct  of  labor  and  the  puerperium,  here  is  the  danger 
of  child-bed  infection  properly  evaluated,  here  only  are  the  refinements  of  an 
operative  technic  possible,  because  the  operator  has  the  help  of  trained  assistants. 
The  newer  procedures — vaginal  cesarean  section,  hebosteotomy,  cesarean  sec- 
tion and  its  modifications,  the  treatment  of  eclampsia,  ruptured  uterus,  asphyxia 
neonatorum,  the  repair  of  lacerations,  etc.,  all  procedures  which  save  life  and  reduce 
invalidism — can  be  carried  out  immeasurably  so  inuch  better  in  the  maternity 
than  at  home,  that  one  could  wish  every  woman  would  go  to  such  a  hospital  for  her 
confinement.  That  the  obviously  pathologic  case  belongs  in  the  hospital  cannot 
even  be  discussed.  Another  benefit  which  is  not  so  generally  recognized  is  the 
effect  on  the  physician.  The  maternity  relieves  him  of  a  great  deal  of  actual  labor, 
it  saves  him  many  hours  of  tedious  waiting,  it  lightens  the  burden  of  responsibility, 
and  the  knowledge  that  he  is  prepared  for  all  emergencies  gives  him  a  feeling  of 
security  which  reflects  itself  in  his  work.  The  drudgery  inherent  in  obstetric 
practice  is  thus  largely  eliminated,  and  the  field  becomes  more  inviting  to  the  best 
men  of  the  profession.  That  such  a  movement  will  have  a  marked  effect  on  our 
obstetric  mortality  and  morbidity  tables  is  self-evident. 

But  the  vast  majority  of  births  occur  in  the  patients'  homes  and  will  continue 
so  in  our  day,  and  it,  therefore,  becomes  our  duty  to  better  the  conditions  we  are 
forced  to  meet.  The  people  must  not  expect  such  good  results  as  are  obtained  by 
the  accoucheur  in  his  specially  equipped  maternity,  but  it  is  surprising  how  much 
may  be  accomplished,  and  with  simple  means.  The  preparations  and  the  obstetric 
satchel  have  Vjeen  described.  It  is  essential  that  the  accoucheur  have  sufficient 
assistants.  Every  labor  case  should  have  two  physicians.  The  duties  of  the  assis- 
tant are,  first,  to  watch  the  fetal  heart-tones  so  that  if  the  child  should  show  signs 
of  exhaustion  or  asphyxia,  it  be  recognized  in  time,  and  the  frequency  of  still-births 
be  thus  diminished;  second,  to  keep  an  accurate  history  of  the  labor;  third,  to 
care  for  the  patient  during  the  first  stage  while  the  accoucheur  is  attending  to  other 
work,  or  obtaining  the  rest  he  will  need  for  the  proper  conduct  of  the  second  and 
third  stages.  In  this  way  an  impending  convulsion,  or  rupture  of  the  uterus,  or 
internal  hemorrhage  or  any  other  complications  will  be  discovered  early  enough 
for  successful  treatment;  fourth,  to  give  the  anesthetic,  and  assist  at  eventual 
operation;  fifth,  to  care  for  the  baby  or  for  the  third  stage,  if  the  accoucheur  is  busy

with  the  bal)y;  sixth,  to  stay  in  the  h(jus('  an  Injur  or  more  after  delivery  to  handle 
a  possible  postpartum  hemorrhage. 

If  (jl)stetries  is  ever  to  attain  the  dignity  of  surgery, — and  it  should, — if  the 
parturient  woman  is  ever  to  enjoy  the  same  benefits  as  the  surgieal  patient, — and 
she  deserves  them, — the  accoueheur  must  be  given  sufficient  help  and  the  make- 
shift policies  of  obstetric  practice  must  be  abolishetl. 

Response  to  the  Call. — The  pregnant  woman  is  to  1m'  instructed  to  summon 
the  physician  imnifilialcly  when  she  feels  that  lal)or  has  begun,  or  when  she  thinks 
that  something — anj'thing  unusual — has  taken  place,  and  the  physician  should 
respond  at  once.  If  the  call  comes  at  a  time  when  he  cannot  answer,  the  ac- 
coucheur sends  his  associate  or  assistant  to  care  for  the  woman  until  his  arrival. 
In  this  way  a  nialprescntation  of  the  child  or  other  complication  may  berecog- 
nized  early,  at  a  time  favorable  for  its  correction,  the  preparations  for  labor  may  l>e 
made  (if  the  patient  has  no  trained  nurse),  the  bowels  and  l)ladder  properly  cared 
for.  and  the  nervousness  of  the  parturient  allayed. 

Arrived  at  the  case,  the  accoucheur  immediately  begins  to  throw  around  the 
patient  all  the  barriers  against  infection,  and  to  study  all  the  conditions,  with  a 
view  to  prevention  and  cure  of  all  possible  complications.  Part  of  this  .study  is  a 
test  of  the  urine  for  albumin,  which  may  very  suddenly  appear,  and  a  general 
physical  examination. — heart,  lungs,  etc., — unless  the  same  has  already  been  made. 

Asepsis  and  Antisepsis. — These  have  reference  to,  first,  the  physician; 
second,  the  patient;  third,  the  environment,  and  the  .same  minute  attention  to 
detail  is  required  a.s  for  an  abdominal  .section.  It  is  a  question  if  the  uterus  can 
care  for  more  infection  than  the  peritoneum. 

Semmelweis,  in  1847,  called  the  attention  of  the  world  to  the  physician  ns  a 
carriir  of  infection,  and  the  latter's  importance  in  this  role  has  been  recognized 
ever  since — in  fact  it  is  exaggerated,  for  the  public  has  held  him  responsil)le  in 
cases  of  sepsis  when  he  was  not  to  blame.  Cases  of  infection  will  occur  under 
ideal  conditions,  and  we  must  look  for  the  cause  elsewhere  than  in  the  accoucheur 
— probably  in  the  woman  herself,  or  even  in  the  husband.  The  precautions  the 
accoucheur  is  to  take,  as  far  as  his  work  is  concerned,  are  well  recognized  and  ought 
to  be  the  common  property  of  the  profession. 

The  accoucheur  should  be  of  clean  personal  habits,  should  not  soil  his  clothes 
l)V  contact  with  postmortem  tables,  pus-basins,  contagious  disease  ca,ses,  etc.,  etc. 
The  accoucheur  should  not  attend  contagious  diseases,  individual  favoral)le  ex- 
perience to  the  contrary  notwithstanding,  xsd  He  Must  ScRiinLorsLY  Aaoio 
Getting  Infective  ^Iaterial  on  His  Hands. 

This  is  the  key-note  of  subjective  a.sepsis  and  cannot  l)e  sufficiently  i-mphasized. 
All  infected  things — pus,  dressings,  etc. — should  be  handled  with  forceps  and  pvr- 
fect  rul)l)er  gloves.  If  the  skin  of  the  hands  is  once  infect eil,  it  requires  two  days  of 
frequent  scrubbings  to  obtain  relative  cleanliness  again.  X<>  nietli(»(l  of  h.inii  <lis- 
infection  will  do  it  at  one  operation.

274  THE   HYGIENE   AND    CONDUCT   OF   LABOR 

practical  purposes  any  one  of  the  above  methods,  if  conscientiousl}'^  carried  out,  and, 
providing  the  hands  have  not  recently  been  soiled  with  virulent  septic  matter, 
will  prove  safe  to  the  patient. 

For  absolute  assurance  against  carrj'ing  infection  the  accoucheur  should  always 
wear  rubber  gloves  in  his  practice,  and  these  have  the  further  real  advantage  that, 
to  a  great  extent,  they  spare  the  sldn  of  the  hands  from  the  corrosive  action  of 
antiseptics.  The  preservation  of  a  smooth  hand  with  well-groomed  finger-nails  is 
an  essential  item  of  an  aseptic  surgical  technic.  The  author  has  not  observed  any 
difference  in  his  results  since  using  rubber  gloves,  but  he  invariably  uses  them  be- 
cause the  frequent  scrubbings  and  applications  of  corroding  antiseptic  solutions 
were  fast  ruining  the  skin  of  his  hands,  and  making  them  harder  and  harder  to 
sterilize.  Other  advantages  of  the  gloves  are:  they  prevent  the  finger-nails  from 
scratching  the  softened  and  delicate  mucous  membrane;  they  render  the  examina- 
tion less  painful  and  distasteful  to  the  woman — the  gloves  appeal  to  her  sense  of  the 
esthetic;  finally,  beside  preserving  the  hands,  the  gloves  reduce  the  dangers  of  in- 
fection of  the  accoucheur  by  sj^hilis,  pus,  etc. 

Objections  urged  against  the  use  of  rubber  gloves  are:  they  interfere  with  the 
sense  of  touch,  making  diagnosis  more  uncertain;  they  do  not  permit  the  use  of  the 
finger  in  puncturing  the  membranes,  in  tearing  through  the  placenta  where  it  is  pre- 
vial;  and  in  removing  fragments  of  placenta  from  the  uterine  wall  when  such  are 
adherent;  they  interfere  wdth  instrumentation,  rendering  operations  more  diffi- 
cult and  prolonged;  they  are  liable  to  tears  and  punctures  which  then  permit 
perspiration,  accmnulated  in  the  hand,  to  escape  into  the  wound. 

It  is  admitted  that,  at  first,  the  gloves  dull  the  sense  of  touch,  but  practice  soon 
restores  it,  and  one  can  feel  as  well  as  before,  even  though  the  glove  be  moderately 
thick.  One  exception  must  be  made  to  this  statement.  It  may  be  impossible  to 
feel  the  untorn  peritoneum  over  a  ruptured  uterus.  The  removal  of  fragments  of 
placenta  from  the  uterine  wall  is  rendered  possible  by  wrapping  one  or  two  fingers 
of  the  operating  hand  with  gauze.  (See  Fig.  714.)  The  gloves  will  interfere 
very  little  with  instrumentation  if  they  fit  w^ell.  The  makers  will,  for  an  insignifi- 
cant extra  charge,  make  a  glove  from  a  model  of  the  accoucheur's  hands.  This 
specialty  fitted  glove  will  hardly  prolong  an  operation,  and,  further,  it  is  less  likely 
to  be  torn  or  punctured.  The  possibility  of  injury  to  the  gloves  is  the  only  real  ob- 
jection to  their  use,  but  this  is  reducible  to  a  negligible  minimum  by  proper  technic. 
In  the  first  place,  the  accoucheur  must  consider  every  puncture  of  the  glove  an  error 
in  technic,  and  throughout  the  operation  must  strive  to  avoid  it.  After  each  opera- 
tion all  concerned  in  it  should  publicly  test  the  gloves  and  make  note  of  the  number  of 
punctures.  Then,  too,  the  operator  should  dispense,  as  far  as  possible,  with  instru- 
ments that  are  sharp  or  have  teeth — for  example,  fork  retractors,  bullet  forceps, 
tenacula.  The  author,  wdth  this  point  in  mind,  has  had  dull  instruments  made  to 
replace  the  rat-tooth  tissue  forceps,  the  vulsellum  forceps,  and  the  rat-tooth  artery 
forceps.  The  ends  of  the  scissors  are  blunt,  and  points,  where  necessary,  are  pro- 
tected as  much  as  possible.  As  a  result  of  these  and  other  precautions  nearly  every 
labor,  and  many  operations — even  craniotomy — are  performed  without  injury  to 
the  gloves. 

An  important  factor  is  the  use  of  dry  sterile  gloves.  If  the  gloves  are  drawn  on 
over  the  wet  hand,  they  macerate  the  skin,  favor  perspiration,  and,  if  punctured, 
allow'  the  accumulated  secretions  to  escape  readily.  The  dry  glove  has  not  these 
objections.  The  puncture  of  one  finger  does  not  communicate  with  the  others,  and 
the  amount  of  secretion  that  escapes  is  negligible.  Further,  it  is  always  understood 
that  the  hands  are  habitually  kept  from  infection  and  are  carefully  sterilized  before 
putting  on  the  gloves.  Without  gloves,  perspiration  and  scraped-off  epithelium  get 
into  the  wound;  with  intact  gloves,  neither  escapes;  with  a  few  punctures,  only  a 
small  portion  escapes,  and  the  chances  of  infection  certainly  are  less  than  with  the 
bare  hand. 


THE    CONDUCT   OF   LABOR  275 

The  advantaRos,  thoroforo,  of  the  gloves  far  outweigh  the  tlisadvantages,  and 
their  use  eunnot  he  too  heartily  reeoniniended.  (See  Aijpciidix  for  methods  of  ster- 
ilizing and  earing  for  gloves.) 

A\'liite  duck  trousers  and  a  sterile  gown  are  recommended  for  wear  during  nor- 
mal (leliver\'  and  ol)stetric  operations.  For  the  hours  of  waiting,  the  accoucheur  i.s 
cleanly  attired  in  a  white  duck  coat.  Street  dirt  and  contagion  are  thus  kept  from 
the  confinement  bed.  The  head-piece  shown  in  Fig.  780  is  used  by  the  author  in 
all  oi)stetric  operations  and  most  ncjrmal  deliveries.  If  the  accoucheur  is  going  t(j 
lecture  during  sudi  a  procedure,  th<'  head-i)ieco  slujuld  surely  he  worn  to  prevent 
infection  from  droplets  of  saliva  exjK'lled  tluring  speaking. 

Without  douht  the  physician  carries  the  greatest  danger  of  infection  to  the 
confinement  room.  The  germs  in  the  air,  in  the  hed-dothes,  in  the  patient's  gar- 
ments, even  those  of  the  vulva,  may  l)e  the  same  in  name  as  those  he  brings 
■with  him,  but  the  former  are  not  virulent,  as  they  usually  have  been  living  a 
saprophytic  existence.  The  physician  comes  in  daily  contact  with  infectious  dis- 
eases, pus,  and  erysipelas  cases,  and  his  person,  dotlies,  antl  especially  his  hands 
carry  highly  virulent  organisms. 

That  everything  intr(jduc(>d  into  the  vagina  should  be  absolutely  sterile  re- 
quires no  mention.  The  author  does  not  carry  already  sterilized  instruments  to 
the  case  because,  to  insure  ])ermanent  sterility,  the  containers  must  be  hermetically 
sealed,  which  is  impractical.  Gauze  and  sponges  in  glass  jars  can  be  thus  carried. 
Instruments  are  boiled  in  2  per  cent,  soda,  borax,  or  lysol  solution,  in  a  tightly 
covered  vessel,  for  five  minutes  just  before  they  are  to  be  used. 

The  Asepsis  of  the  Patient. — Using  culture-media  very  favorable  to  its  growth, 
Kronig  and  Pankov  have  shown  that  the  streptococcus  pyogenes  exists  in  75 
per  cent,  of  the  vaginas  of  pregnant  women  and  in  nearly  all  jiuerpera^.  Walt  hard 
found  pathogenic  bacteria  in  27  per  cent,  of  the  vaginas  of  i)regnant  women,  and 
these  bacteria  couUl  be  made  virulent  by  proper  cultural  methods.  The  uterus  and 
upper  third  of  the  cervix  are  sterile,  but  the  vagina  is  often,  and  the  vulva  always, 
infected  with  non-pathogenic  and  pathogenic  bacteria.  A\'hy  does  not  everj'  woman 
in  labor  become  infected?  AMiy  does  not  ''autoinfection"  occur  more  often? 
Autoinfectit)a  meaiLS  the  develoi)ment  of  sepsis  during  the  puerperium  from  germs 
which  existed  somewhere  in  the  woman's  person  at  the  time  of  labor.  Its  existence 
was  recognized  by  Semmelweis,  later  denied  by  many  authorities,  but  recently  ad- 
mitted as  possible,  but  of  great  rarity,  by  the  majority  of  students  of  the  subject. 
The  reasons  for  the  rare  appearance  of  infection  are:  the  parturient  has  developed 
immunities  against  the  germs  which  have  made  the  vagina  their  habitat ;  the  proc- 
ess of  lai^or  is  a  continual  scouring  out  from  above,  the  How  of  the  liquor  amnii,  the 
progress  of  the  child  and  the  jilacenta,  the  running  of  l)lood,  all  from  abov(>  down- 
ward, all  oppose  the  upward  wandering  of  the  vaginal  bacteria;  the  vaginal  nuicus 
has  slight  bactericidal  properties;  the  bacteria  have  a  low  virulence  during  labor, 
acquiring  invasive  properties  only  after  the  third  tlay  j)ostpartum,  but  by  this 
time  the  puerperal  wounds  are  covered  by  granulations  which  oi)pose  their  attacks. 

Let  the  natural  innnunities  be  broken  down, — as  by  severe  hemorrhage,  shock, 
eclami)sia,  etc., — or  let  a  new  virulent  bacterium  be  introduced;  let  the  accoucheur 
in  his  manipulations  carry  too  many  of  the  vaginal  bacteria  up  into  the  uterus  (a 
procedure  not  entirely  avoidable),  or  let  him,  by  his  operations,  bruise  and  nuitilate 
the  parts  too  much,  or  let  him  break  up  the  protective  gramilations  above  referred 
to,  and  the  germs  will  rapidly  invade  the  system,  producing  a  disea.-^e  known  as 
''puerperal  infection,"  ti-rmetl  by  the  older  writers  "child-bed  fever." 

The  asejisis  of  the  patient,  tlierefore,  consists  mainly  in  the  preservation  of  Iht 
immunities  by  sustaining  her  strength,  procuring  a  normal  course  of  labor,  avoiding 
the  necessity  for  operative  interference,  and  conducting  these  with  the  lea.>^t  possible 
amount  of  tlamage.     By  restricting  the  internal  examinations  and  conducting  the 


276  THE    HYGIENE   AND    CONDUCT   OF   LABOR 

labor  by  external  examination  and  observation  of  its  course,  we  avoid  carrying  the 
infective  material  present  in  the  vagina  into  the  tissues. 

In  brief,  the  two  main  principles  are :  Limit  the  number  of  the  puerperal 
wounds,  and,  second,  prevent  infection  of  the  necessary  puerperal  wounds. 

How  to  carry  out  these  principles  will  occupy  our  attention  throughout  all  the 
chapters  devoted  to  the  practical  application  of  the  science  of  obstetrics. 

The  Antepartum  Bath. — As  generally  practised,  the  preparatory  bath  given 
in  a  tul)  is  tlang(n-ous,  because  the  wash-water,  with  the  diluted  soil  from  the  body, 
gets  into  the  vagina.  Bacteriologic  proof  is  not  necessary  to  convince  one  of  this 
fact.  Any  woman  who  has  had  children  will  know  that  the  water  of  her  bath  fre- 
quently gains  entrance  to  the  vagina.  Stroganoff  has  shown  that  the  morbidity  of 
the  maternity  in  St.  Petersburg  has  improved  since  the  shower  was  substituted  for 
the  tub-bath,  and  the  author  recommends  the  shower  in  the  antepartum  prepara- 
tion. First,  the  pubic  region  is  carefully  shaved,  as  for  a  gynecologic  operation. 
A  safetj^  razor  is  best  for  this  purpose.  Then  the  whole  body  is  scrubbed  with  soap 
and  water.  In  hospitals  a  shampoo  table  is  used.  The  person  is  then  showered 
with  lukewarm  water,  after  which  the  pudendal  region  is  again  scrubbed  with  soap 
and  hot  water,  using  a  wash-cloth  (no  stiff  brush),  and  paying  especial  attention  to 
the  folds  around  the  clitoris.  Accumulated  smegma  is  removed  with  olive  oil, 
albolene,  or  soft  soap.  After  the  soap  has  been  rinsed  off,  the  region  from  the  ensi- 
form  to  the  knees  is  liberally  sponged  with  1  :  1500  bichlorid  of  mercury,  again 
paying  especial  attention  to  the  pudenda. 

Before  the  bath  is  given,  a  colonic  flushing  of  soapy  water  is  administered,  and 
the  patient  empties  her  bladder.  After  the  bath,  the  patient  is  thoroughly  dried 
with  a  sterile  towel,  dressed  in  sterile  night-dress  and  stockings,  with  clean  slippers 
and  house  dress,  and  conducted  to  the  confinement  room. 

The  Antepartum  Douche. — Since  germs  with  virulent  possibilities  are  natur- 
ally present  in  the  vagina^  of  parturients,  it  would  seem  wise  to  disinfect  the  vagina 
as  we  do  before  gynecologic  operations.  Theoretic  consideration  and  practical 
experience,  however,  show  that  attempts  to  sterilize  the  vagina  before  labor  invite 
the  infections  we  seek  to  avoid.  The  scrubbing  of  the  vagina  and  cervix  robs  the 
mucous  membrane  of  its  protective  mucus  and  epithelium;  the  strong  chemical 
antiseptics  kill  the  delicate  cells  before  they  affect  the  bacteria.  All  that  the  treat- 
ment does  is  to  remove  some  of  the  germs  and  the  secretions,  and  within  a  few  hours 
afterward  the  germs  are  as  numerous  as  before.  The  tissues,  however,  have  sus- 
tained permanent  injury,  and  their  natural  immunities  have  been  reduced.  Ex- 
perience in  the  Leipzig  clinic  under  INIenge,  in  parallel  cases,  treated  with  and  with- 
out vaginal  antisepsis,  has  shown  a  higher  morbidity  in  the  former  class.  If  vaginal 
antisepsis  were  necessary  for  good  results,  the  Chicago  Lying-in  Hospital  and  Dis- 
pensary, under  the  author's  management,  would  show  a  higher  mortality  from  sep- 
sis than  5  deaths  in  L5,000  cases.  In  2  of  these  cases  sexual  intercourse  had  oc- 
curred within  a  few  hours  of  the  deliver}^  of  the  child. 

Further,  it  is  as  little  possible  to  sterilize  the  vagina  as  it  is  to  sterilize  the  skin. 
The  author  does  not  use  antiseptic  vaginal  douches  as  a  routine.  Before  operations, 
just  before  introducing  the  hand  into  the  uterus,  the  vagina  is  liberally  flushed  ^^dth 
I  per  cent,  lysol  solution  from  pledgets  of  cotton  held  in  the  hand,  the  idea  being  to 
reduce  the  amount  of  infectious  matter  unavoidably  carried  into  the  puerperal 
wounds  by  the  manipulations. 

Under  Asepsis  of  the  Patient  may  be  mentioned  abstinence  from  coitus  during 
the  last  month  of  pregnancy.  The  danger  of  such  a  bestial  practice  is  a  real  one,  as 
the  two  cases  just  referred  to  will  indicate.  In  one  of  these  two  cases  the  procedure 
ruptured  the  membranes,  the  infant  was  born  as  the  medical  attendant  entered  the 
room,  and  the  rest  of  the  labor  was  conducted  without  any  internal  examinations 
or  treatment  whatever.

actual  labor  has  commenced.  Suflicicat  provision  must  al>o  havi'  been  made  for 
light,  especially  for  ojHTations  at  night.  The  room  should  be  conveniently  arranged, 
some  thought  having  been  given  to  it.     P^ig.  290  is  an  example. 

The  bed,  preferal)ly  a  narrow  one,  is  moved  away  from  the  wall.  Three  table 
boards  or  shelves  from  a  book-ca.se  are  put  under  the  mattre.ss.  on  top  of  the  spring, 
to  give  it  a  tal»le-like  character,  and  to  ])revent  .sagging  in  the  center.  The  mattre.s.s 
is  covered  with  a  long  rul)l)er  cloth;  over  this  comes  a  sheet ;  at  the  middle  of  the 
bed  is  put  a  small  ruliber  protector,  and  over  this  a  sterile  sheet,  folded  once,  and 
all  securely  j^inned  \\'ith  safety-pins.  If  the  patient  has  no  rubber  sheeting,  the 
mattre.ss  is  covered  with  five  layers  of  clean  newspapers,  and  these  also  substitute 
the  small  rubber  sheet  under  the  buttocks.  Sterile  newspajx^rs  are  ea.>^ily  procured, 
and  they  may  be  used  in  many  places  instead  of  sterile  tow«'ls.     .\  larce  Imndle  may

be  baked  in  the  oven  like  a  loaf  of  bread.  The  dresser,  side-tables,  and  chairs  on 
which  the  solution  basins  arc  laid  are  to  be  covered  with  newspapers. 

To  carry  the  solution  basins,  instrument  tray,  and  pile  of  sterile  towels,  the 
ordinary  sewing-table  serves  admirably,  additional  table  room  being  obtained  by 
means  of  the  ever-present  euchre-table.  The  table  from  the  kitchen  or  a  strong 
library  table  is  used  for  all  o]")erations.  With  a  degree  of  effort  and  forethought  the 
conditions  of  th(>  lying-hi  hospital  deliver^'  room  may  be  successfulh^  imitated. 

The  First  Examination. — On  entering  the  lying-in  chamber  the  accoucheur 
takes  note  of  the  general  appearance  of  the  parturient,  the  frequency  and  strength 
of  the  i^ains,  takes  the  pulse,  and  later  the  temperature.     It  is  not  always  necessary

to  proceed  to  the  examination  at  once:  the  first  few  minutes  may  be  devoted  to 
general  observations  unless  the  indications  point  to  a  quick  delivery.  The  accou- 
cheur then  takes  off  coat  and  cuffs,  rolls  sleeves  alcove  the  elbow,  puts  on  an  apron, 
washes  the  street-dirt  off  his  hands,  cleans  his  finger-nails  carefully,  and  scru])s  his 
hands  and  forearms  vigorously  with  soap  and  hot  running  or  frequent  changes  of 
water  for  five  minutes  by  the  clock.  The  nurse  in  the  mean  time  prepares  the  pa- 
tient for  the  external  examination,  bringing  her  near  the  side  of  the  bed,  uncovering 
the  abdomen,  but  covering  the  limits  and  chest  with  a  sheet  and  a  towel.  The 
physician  dries  and  warms  liis  hands  and  proceeds  with  the  abdominal  exploration. 
Five  questions  must  be  answered:    (1)  Is  the  woman  pregnant?     (2)  How  many 


THE    CONDUCT   OF    LABOR 


279 


children  has  she  had?  (3)  Is  she  at  term?  (4)  Is  she  in  labor?  (5)  Complete 
(liaiiMosis  of  the  case.  The  first  three  (|uestions  will  have  been  answered  by  the 
jjicfiiiancy  examinations  unless  the  physician  is  first  called  durinj^  labor,  but  let  a 
warning  be  sounded  not  U)  take  too  nmch  f(jr  granted,  but  to  proceed  on  the  safe 
grounds  of  a  careful  physical  objective  examination.  Is  the  woman  in  labor?  The 
regular  character  of  the  pains,  the  hardening  of  the  uterus,  the  show,  the  proved 
rupture  of  the  membranes,  and  the  findings  on  internal  examination  will  determine 
this  j)oint;  but  lal)or  may  cease,  even  after  i)artial  or  complete  dilatation  oi  the 
cervix,  and  pregnancy  continue  for  days  or  weeks.  The  pains  cease,  the  os  clcses, 
and  the  incident  is  called  a  "false  alarm."  False  pains  are  painful  uterine  contrac- 
tions occurring  during  the  latter  part  of  pregnancy,  not  followed  by  dilatation  of 
the  cervix  or  the  appearance  of  a  show.     They  often  attend  lightening,  may  (K'cur

at  night,  not  seldom  repeat,  and  ina\'  suuniion  the  pli>sieian  and  nurse  on  a  fruitless 
errand.     A  warm  l)ath  and  an  enema  or  a  dose  of  bromid  will  disi)el  tliem. 

The  diagnosis  of  position  and  presentation  by  abdominal  examination  was  first 
developed  by  Pinard,  and  has  since  l)een  amplihed  by  many  authors.  One  should 
have  a  certain  plan,  which,  if  followed,  will  lead  to  accurate  results  and  prevent 
omis.sions.  After  noting  the  size  and  shape  of  the  uterine  tumor,  the  following  four 
qu(^stions  are  answered:  (1)  Is  the  uterine  ovoid  longitudinal  or  transverse?  (2) 
What  is  over  the  inlet?     (3)  What  is  in  the  fundus?     (4)  Where  is  the  back? 

1.  The  hands  are  laid  on  either  side  of  the  belly,  and  the  uterine  tumor  straight- 
ened between  them,  thus  easily  determining  if  the  fetal  and  uterine  ovoid  lies  paral- 
lel with  the  long  axis  of  the  mother  or  not.  If  it  is  parallel,  the  presentation  is 
either  head  or  breech;  if  not,  we  are  dealing  with  an  oblique  or  a  tran.sverse  presen- 
tation (Fig.  297).

2.  The  two  hands  are  gcnitly  pressed  into  the  inlet  of  the  pelvis  from  the  iliac 
fossae.  If  they  find  a  hard,  Inill-sluiped  body,  it  is  the  head.  If  they  eonie  almost 
together  above  the  inlet,  it  means,  first,  that  the  head  is  very  high,  not  having  begun

to  engage;  or,  second,  that  the  breech  Hes  over  the  inlet  and  is  hkewise  pushed  up; 
or,  third,  that  there  is  no  part  over  the  inlet,  the  shoulder  presenting  and  not  being 
engaged.  If  the  fingers  come  together  on  a  soft,  irregular  body,  it  is  the  breech  in 
the  process  of  engagement  (Fig.  298). 

3.  The  two  hands  are  laid  on  the  fundus  uteri,  the  examiner  now  facing  the 
mother.  In  the  other  manoeuvers  his  back  was  toward  her  face.  Attempting  to 
grasp  the  object  in  the  fundus  between  his  two  hands,  he  determines  its  hardness  and 
shape,  and  differentiates  between  the  hard,  round  head  and  the  softer,  irregular 
breech.     It  is  often  easy  to  feel  the  genital  crease,  the  crests  of  the  ilia,  and  the 


Fig.  301. — Palpating  the  Anterior  Shoulder  in  O.L.T. 


small  extremities  of  the  child  (Fig.  299).  If  he  finds  the  fundus  pushed  to  one  side 
or  full  of  small  parts,  he  suspects  transverse  presentation  or  uterus  unicornis. 

4.  The  location  of  the  back  is  determined  by  laying  the  hands  on  the  belly,  as 
for  the  first  manoeuver,  and  pressing  alternateh'  inward  toward  the  navel  with  them. 
The  back  offers  more  resistance,  allows  the  hand  to  be  pressed  in  less,  and  can  usually 
l)e  felt  as  such. 

Having  thus  mapped  out  the  child,  one  proceeds  to  the  finer  diagnosis  of  the 
position  and  attitude.  The  head  is  studied  first.  Two  hands  press  do^^^lward 
toward  the  linea  innominata.  The  occiput  lies  deeper  in  the  pelvis;  it  is  flatter 
than  the  forehead,  nearer  the  middle  line,  and  harder  to  outline.     The  forehead  is 


282 


THE    HYGIENE   AND    CONDUCT   OF    LABOR 


reached  sooner  by  the  advancing  hand,  is  angular,  further  from  the  middle  line,  and 
easier  outlined.  Having  thus  located  these  two  points,  the  position  of  the  head 
becomes  clear.  The  forehead  cannot  be  distinguished  from  the  occiput  when  the 
head  is  deflexed  in  face  presentation;  but  here  we  have  corrective  means  of  diag- 
nosis. Another  method,  bj'  a  single  grasp  to  palpate  the  head,  is  illustrated  in 
Fig.  300.  An  expert  diagnostician  may  often,  with  this  one  grasp,  diagnose  the 
presentation,  position,  and  degree  of  engagement  of  the  head.  One  determines  the 
position  of  the  head  in  the  pelvis  by  the  relation  of  the  occiput  and  the  forehead  to 
the  inlet.     If  the  forehead  is  felt  to  the  right  side  behind,  and  the  hand,  to  reach  the

Four  fingers  of  the  right  hand  are  laid  in  the  broad  base  of  the  triangle  and  feel  the  side  of  the  fetus. 

the  thigh  is  felt,  and  downward,  the  arm. 


Pushing  upward 


occiput,  sinks  deeply  behind  the  left  ramus  of  the  pubis,  the  position  is  O.L.A.  If 
the  forehead  is  over  the  left  pubic  ramus,  it  is  O.D.P.  Another  method  of  determin- 
ing position  is  by  locating  the  shoulder  (Fig.  301).  One  hand  passes  upward  from 
the  rounding  of  the  head  and  comes  to  rest  on  a  soft  prominence — the  slioulder.  If 
this  is  in  the  median  line  or  to  the  right  of  it,  when  the  back  is  on  the  left  side,  the 
position  is  O.L.A. ;  if  to  the  left  of  the  median  line,  the  position  is  O.L.T.  or  O.L.P., 
and  correspondingly  when  the  back  is  on  the  right  side.  Passing  upward  the  hand 
feels  a  triangular  space  (Fig.  302)  made  by  the  side  of  the  baby's  trunk — the  thigh 
above  and  the  arm  below.     Still  another  method  of  determining  the  position  of  the 


THE   CONDUCT   OF   LABOR 


283 


head  in  the  pelvis  is  the  study  of  the  relation  of  the  feet  to  the  breech  and  the  breech 
to  the  cjuadrants  of  the  fuiwhis  (Fi^-  308).  Careful  study  of  the  subject  has  con- 
vinced the  author  that  the  breech  and  trunk  very  closely  follow  the  movements  of 
the  head,  so  that,  for  example,  if  one  finds  the  breech  in  a  position  which  it  would 
occupy  in  O.L.P.,  the  head  will  lie  in  this  position,  and,  by  definitely  outlining  the 
breech,  one  may  deduce  the  position  of  the  head.  The  fundus  is  marked  out  with  a 
circle  and  divided  into  four  (|uadrants.  If  the  breecli,  with  the  small  parts,  is 
found  in  the  left  antericjr  quadrant ,  tiie  p(jsition  is  occipitolajva  anterior,  O.L.A.; 
if  in  the  rij;ht  posterior  (juadrant,  the  head  lies  O.D.P.

The  Emjiujemcnt  of  the  Presenting  Part. — What  is  tiie  de<;ree  of  engagement? 
Where  does  the  head  stanil? — a  most  important  question,  which  nuist  be  answered 
several  times  in  every  labor.  (1)  Place  the  two  hands  on  the  head,  as  in  Fig.  299, 
and  try  to  move  the  head — or  breech — from  side  to  side.  If  movable,  the  part  is 
not  engaged.  (2)  Note  how  much  of  the  heail  can  be  felt  above  the  inlet,  using  the 
pul)is  as  a  landmark.  If  only  tiie  forehead  is  palpaltle.  and  that  on  (hvp  pressure, 
the  head  is  well  engaged.     Other  information  is  obtained  on  internal  examination. 

The  Location  of  the  Placenta. — In  a  few  instances  this  may  be  discovered  at  this 
time,  though,  excejit  in  ca.ses  of  placenta  pra^via  and  cesarean  section,  the  infonna- 
tion  is  of  little  value.  Tiie  i)lacental  site  has  a  l)oggy  feel,  the  i>arts  underneath  are 
less  sharp,  and  sometimes,  if  tlu^  alxlominal  wall  is  thin,  one  may  see  a  somewhat 
circular  groove  on  the  uterus.     When  the  placenta  is  on  the  anterior  w.tll.  flu-  mund 


284  THE   HYGIENE   AXD    CONDUCT   OF    LABOR 

ligaments  are  pushed  to  the  sides,  and  when  the  organ  occupies  the  posterior  wall, 
the  round  ligaments  converge  on  the  front  of  the  uterus  (Figs.  102  and  103,  y.  81) 
(Leopold  and  Bayer).  There  are  no  auscultatory  signs  which  may  be  used  in 
locating  the  placenta  in  the  uterus. 

The  round  ligaments,  their  course,  thickness,  tenseness,  and  tenderness,  should 
be  studied  and  noted. 

Now  the  pelvis  is  measured,  unless  this  has  been  done  before  labor  (see  p. 
233),  and  an  opinion  is  to  be  formed  of  the  amount  of  resistance  the  child  will 
meet.  This  comprehends  the  palpation  of  the  child  and  the  formation  of  a  mental 
picture  of  its  size,  also  fetal  mensuration.  It  is  a  good  plan  to  write  down  the 
probable  weight  of  the  child,  to  gain  experience  in  estimating. 

The  presence  of  tumors  in  the  uterus  or  abdomen,  ascites,  tympany,  excessive 
or  unusual  tenderness,  should  all  be  noted.  One  may  feel  the  umbilical  cord  cours- 
ing over  the  fetal  back  or  around  its  neck;  also  feel  unusual  fetal  movements,  as 
hiccups  and  gasps;  or  may  determine  a  fetal  anomaly,  as  hydrocephalus,  twins,  etc. 

Auscultation. — It  is  better  to  make  the  diagnosis  of  presentation  and  position 
by  abdominal  palpation,  and  confirm  it  by  locating  the  fetal  heart,  than  to  rely  on 
the  location  of  the  tones  to  give  the  former  information,  because  there  are  vagaries 
in  the  transmission  of  the  heart-sounds  which  may  mislead.  Fig.  221,  p.  194,  shows 
the  location  and  course,  during  labor  in  O.L.A.,  of  the  fetal  heart-tones,  and  Fig.  227 
the  same  in  O.D.P.  As  labor  progresses,  the  child  advancing  and  rotating,  the 
point  of  greatest  intensity  of  the  heart-sounds  comes  anteriorly  and  sinks,  until, 
when  the  head  is  distending  the  perineum,  the  sounds  will  be  best  heard  just  over 
the  pubis.  The  auscultation  of  the  fetal  heart  gives  invaluable  information  as  to 
the  life  and  condition  of  the  child.  Normally,  the  rate  is  120  to  150  a  minute,  and 
the  beat  is  regular  and  rhythmic.  Any  slowing  below  120,  or  increase  above  150, 
is  suspicious  of  danger  threatening  the  infant,  as  also  is  irregularity  of  the  beat  or 
lack  of  the  normal  rhythm.  This  subject  will  again  be  considered  under  the  subject 
of  Asphyxia  Neonatorum.  Suffice  to  say  here  that  the  fetal  heart-tones  must  be 
studied  every  hour  or  two  during  the  first  stage  of  labor,  and  every  fifteen  to  twenty 
minutes,  or  even  continuously,  in  the  second  stage,  for  the  purpose  of  early  dis- 
covering any  danger  which  may  beset  the  infant  in  utero.  One  may  hear  the  funic 
souffle,  especially  if  the  cord  lies  over  the  fetal  back  or  is  coiled  around  the  neck, 
and,  if  it  is  found,  still  greater  caution  is  required. 

Finally,  the  observer  studies  the  uterine  contractions,  noting  their  character, 
frequency,  and  strength.  The  uterus  is  the  engine  of  deliverj^,  and  the  physician, 
as  does  the  engineer,  must  know  the  power  of  the  machine  that  does  the  work.  Too 
little  power,  too  much  power,  great  power  against  great  resistances — all  such  prob- 
lems must  be  solved  by  the  obstetrician  during  his  observations.  The  main  points 
in  the  abdominal  examinations  arc: 

1.  Accurate  diagnosis  of  presentation  and  position. 

2.  Determination  of  the  degree  of  engagement. 

3.  Condition  of  the  child  in  utero. 

4.  Character  of  the  uterine  action. 

5.  Consideration  of  the  pelvic  measurements  and  determination  of  the  size  of 
the  child,  and  the  kind  and  amount  of  resistance  the  latter  will  meet  in  its  passage 
through  the  former. 

The  value  of  the  external  examination  is  that  we  can  get  the  information  quicker, 
earlier,  less  painfully,  and  with  no  detriment  to  the  patient.  A  large  number  of 
labors  can  be  conducted  successfully  without  any  internal  examinations,  and  as  one's 
experience  grows  one  will  be  able  to  do  this  more  and  more.  Still,  expediency  for- 
bids its  exclusive  practice.  For  the  sake  of  asepsis  one  limits  the  internal  examina- 
tions to  an  irreducible  minimum,— a  grateful  change  from  the  meddlesomeness  of 
olden  practices, — and  if  the  accoucheur  has  the  time,  if  the  presentation  and  posi- 


THE   CONDUCT   OF   LABOR 


285 


tion  are  good  and  the  fetal  heart-tones  normal,  it  is  not  necessary  to  make  any 
internals  during  this  stage,  a  practice  that  cannot  Ije  too  highly  commended.  A 
vaginal  examination  is  ma<le,  when  necessary,  to  complete  the  prlvic  measurements; 
to  diagnose  the  j)()sit  ion.  if  such  was  impossible  In-fore;  hut  mainly  to  (h-termine  the 
degree  of  effacement  and  dilatation  of  the  cervix  and  the  progress  of  labor,  and 
as  to  whether  the  accoucheur  is,  or  is  not,  required  to  remain  at  the  lx,*dside  of 
the  parturient. 

Internal  Examination. — The  nurse  is  recjuested  to  dra])*-  the  patient  for  the 
internal  examination  (Fig.  304).  This  is  always  crjnducted  by  sight.  The  ])a- 
tient  lies  on  her  Jjack,  near  the  edge  of  the  bed,  but  with  fat  women,  and  when*  the 
diagnosis  promises  to  be  difficult,  she  is  best  placed  across  the  bed,  or  even  on  a  table, 
in  the  lithotomy  position.  A  sheet  covers  her  jierson,  the  ends  being  twisted  anjund 
the  legs,  leaving  the  genitalia  exposed.  Antiseptic  solutions  are  prei)ared  (jn  a 
table  near  the  bed — 1  :  lOOO  ))ichlori{l  of  mercury  and  1  per  cent,  lysol,  each  basin

genitalia  have  already  been  disinfected,  in  the  primary  preparation  of  the  patient 
the  physician  needs  only  to  liberally  sponge  the  labia  anil  introitus  with  lysol  solu- 
tion, then  with  the  bichlorid,  and  again  with  the  lysol  solution,  leaving  a  piece  of 
cotton  soaked  in  the  latter  lying  in  the  vulvar  canal.  He  now  washes  his  hands 
again  in  the  bichlorid  solution,  dries  and  powders  them,  and  draws  on  his  sterile 
rubber  gloves.  The  talcum  powder,  which  coats  the  gloves  during  sterilization,  is 
washed  otY  in  the  two  antiseptic  solutions,  and  then  two  hngers  of  the  left  hand — 
taking  care  to  touch  nothing  on  the  way — are  carried  to  the  vulva,  removing  the 
bit  of  cotton  left  there.  Then, separating  the  labia  widely  withthe  imlex-aml  middle 
finger  of  the  other  hand,  the  two  fingers  enter  the  vagina,  pa.ssing  at  once  tlivply 
into  the  canal,  after  which  the  labia  are  allowed  to  come  together  on  the  examining 
fingers  (Fig.  oO.")j.  ( Ireat  care  is  to  be  employed  to  avoid  the  anal  region,  the  fingers 
coming  in  contact  only  with  the  mucous  membrane  of  the  introitus  vagina\  and  the 
inside  of  the  two  sterile  fingers  spreading  the  lal)ia.  These  fine  details  are  given 
because  of  the  importance,  from  an  antiseptic  point  of  view,  of  the  internal  examina- 
tion, and  it  being  so  difficult  to  avoid  carrying  infection  from  the  surface  into  the 
vagina  and  uterus. 


286  THE   HYGIENE   AND    CONDUCT    OF    LABOR 

Each  and  every  examination  is  to  be  conducted  with  the  same  care.  Six  points 
are  to  be  determined  during  vaginal  exploration,  and  the  laws  of  asepsis  demand 
that  they  be  made  in  a  certain  order : 

1.  The  Degree  of  Effacement  and  Dilatotion  of  the  Cervix. — The  fingers  pass 
quickly  to  the  cervix,  noting  its  consistence  and  size,  whether  the  external  os  is  open, 
or  the  cervical  canal  shortened  or  effaced.  The  varjang  degrees  of  effacement  and 
dilatation  have  been  described  and  illustrated  on  pp.  119-123.  One  will  speak 
of  the  cervix  being  effaced  and  the  os  admitting  three  or  four  fingers,  or  as  being  the 


ft

size  of  a  quarter,  etc.  The  author  prefers  to  use  metric  terms,  saying  the  os  is  two, 
three,  or  more  centimeters  across. 

Occasionally  one  will  find  the  cervix  partly  effaced,  much  softened,  or  even 
somewhat  dilated,  without  there  having  been  many  uterine  contractions.  This  is 
called  "insensi})le  labor,"  and  is  very  welcome  in  operative  cases. 

2.  Has  the  Bag  of  Waters  Ruptured? — The  answer  is  usually  easy,  but  may 
present  great  difficult}^  If  the  membranes  are  of  watch-crystal  form,  one  feels  a 
tense  membrane,  a  short  distance  below  the  head,  during  a  pain.  In  the  interval 
this  membrane  is  relaxed.     If  the  membranes  are  pressed  tightly  against  the  head

like  a  rap,  it  ma}'  ho  possible,  ])y  j)usliinf;  the  licad  up  a  little,  to  notice  liquor  amnii 
flowing;  ilown  between  the  bag  and  the  head,  and  no  llui<l  will  escape  alongside  the 
fingers.  A  practised  touch  will  be  able  to  distinguish  between  the  smooth  chorion 
or  anniion,  and  the  rough,  hairy  scalp.  An  attempt  to  wrinkle  the  scalj)  with  tlie 
fingers,  or  catch  a  lock  of  hair  between  them,  if  successful,  will  show  that  the 
membranes  are  ru[)tured,  and  the  head,  when  j)ushed  uj).  will  allow  liquor  amnii 
to  flow  into  the  hand.  The  discharge  of  li(|Uor  anmii,  of  vernix  ca.seosa,  or  flakes 
of  meconium  will  clinch  the  diagnosis.  In  doubtful  ca.ses  the  vagina  may  be 
opened  by  broad  specula  or  the  fingers,  and  the  i)resence  of  the  membranes  over 
the  head  determined  by  sight.  The  inig  of  waters  may  rujiture  in  two  i)Iaces — 
the  first  time  high  up,  the  second  over  the  os;  and  there  may  be  two  l)ags,  as  in 
twins,  or  there  may  be  an  accunmlation  of  litjuid  between  the  anmion  and  chorioiL 
'.i.  The  Diagnosis  of  Presentation  and  Position. — If  the  external  examination 
has  Ix'cn  thorough,  little  more  is  t(j  be  learned  fnjm  the  internal,  except  to  confirm 


\

or  correct.  (The  findings  on  internal  examination  have  been  described  on  p.  103, 
to  which  the  reader  is  referred.)  It  is  usually  impo.ssible  to  outline  the  sutures  and 
fontanels  through  the  cervical  wall,  but  tiie  memltranes  do  not  hinder  it  except  liur- 
ing  the  pains.  After  deciding  that  the  hard,  roundish  Ixxly  is  the  head,  and  the 
occipital  part, — not  the  face  or  brow, — the  finger  seeks  the  sagittal  .suture.  If  it  is 
near  the  promontory,  the  head  is  in  Xaegele's  obliquity,  or  anterior  asyndyt ism; 
if  near  the  pubis,  in  posterior  a.syndyti.sm;  if  median,  it  is  s\iu'lytic.  Following 
the  suture,  the  fontanels  are  felt — the  lozenge-shai)e(l  one  is  the  largest,  and  ha.s 
four  sutures  running  to  it;  the  Y-shapetl  one  is  the  smallest,  having  onW  three 
sutures  running  to  it.  The  angle  of  the  Y  points  to  the  face;  the  obtu.se  imgle  of 
the  lozenge  points  back  toward  the  occijiut.     (See  Figs.  101  and  102.) 

Th(>  lateral  fontanels  may  imjiose  as  the  large  or  small,  but  one  always  finds  the 
ear  close  by,  and  the  zygomatic  jirocess  with  the  eilge  of  the  orlnt.  A  false  fontanel 
\y\\\  confuse  the  diagnosis,  and  its  presence  shouKl  always  be  susix«cted  when  the 
findings  are  not  typical.     To  distinguish  the  sagittal  suture  from  the  lambdoid  or 


288  THE    HYGIENE   AND    CONDUCT   OF    LABOR 

coronary,  it  is  to  bo  noted  that  the  latter  two  lie  in  stron<>;ly  curved  planes,  the 
sagittal  lying  in  a  less  arched  surface.  Certainty  in  defining  the  position  of  the 
head  can  almost  always  be  obtained  by  these  means,  but  in  cases  of  doubt  it  is  well 
to  search  for  the  ear.  The  position  of  the  car  vdW  disclose  the  position  of  the  head. 
In  the  second  stage,  after  hard  labor  pains  have  molded  the  head  and  developed  on 
it  a  caput  succedaneum,  the  landmarks  are  obscured,  but  still  discoverable;  and, 
again,  recourse  may  be  had  to  the  ear. 

4.  The  Advancement  of  the  Head  Along  the  Birth-canal. — Again,  the  external 
examination  has  su])i>licd  much  information;  but  in  many  cases  the  degree  of  en- 
gagement can  be  determined  only  by  internal  exploration. 

The  head  is  ''floating"  when  it  is  freely  movable  above  the  inlet.  It  is  ''fixed 
in  the  inlet"  when  moderate  pressure  will  not  dislodge  it,  but  its  parietal  bosses  have 
not  yet  passed  the  region  of  the  inlet. 

The  head  is  "engaged"  when  its  greatest  transverse  plane  has  passed  the  region 
of  the  inlet.  In  occipital  presentation  this  is  the  biparietal  plane,  and  "engage- 
ment" is  sho^\^l  clinically,  first,  by  the  lowest  part  of  the  head  having  reached  the 
interspinous  line  or  passed  it ;  second,  by  the  covering  of  the  sacrum,  two-thirds ; 
third,  by  the  covering  of  the  symphysis,  three-fourths,  by  the  advancing  head. 
The  head  is  in  the  "midplane"  when  the  lowest  part  of  the  vault  lies  between  the 
tuberosities,  and  "at  the  pelvic  outlet"  when  two  parietal  bosses  are  passing  the 
tuberosities.  After  this  the  head  comes  well  do\vn  "on  the  perineum"  and  lies  in 
the  distended  vagina  and  vulva.  By  first  touching  the  top  of  the  head  and  then 
carrying  the  fingers  to  the  bony  wall  of  the  pelvis,  it  is  easy  to  determine  the  rela- 
tion of  one  to  the  other,  especially  if  the  manceuver  is  combined  with  external  palpa- 
tion. Too  great  emphasis  cannot  be  laid  on  the  importance  of  accurately  defining 
the; location  or  "station"  of  the  head  in  the  birth-canal.  Before  operating  this  in- 
formation is  absolutely  essential. 

5.  Abnormal 'dies. — The  finger  now  notes  any  abnormality,  the  presence  of  the 
cord  or  fetal  parts  in  the  vagina,  tumors,  excessive  rigidity  of  the  perineum,  etc. — 
points  which  wall  be  touched  upon  later. 

6.  Internal  Pelvimetry. — Unless  the  pelvis  has  been  carefully  measured  before, 
it  is  done  now,  or  a  previous  examination  supplemented.  Running  the  fingers 
slowly  over  the  bony  walls,  the  general  size  of  the  cavity  is  appreciated,  the  size 
and  sharpness  of  the  ischiatic  spines  determined,  the  sacrum  and  posterior  wall  of 
the  pubis  and  as  much  as  possible  of  the  linea  terminalis  are  palpated ;  finally,  the 
fingers  take  the  conjugata  diagonaUs.     (See  p.  241,  Fig.  271.) 

In  the  first  examination  all  these  six  points  are  to  be  elicited,  and  in  the  order 
named.  By  going  slowly  and  gently  the  patient  is  not  hurt,  and  all  the  required 
information  will  be  gained.  During  a  labor  pain  one  must  he  careful  not  to  rupture 
the  membranes,  but  it  is  justifiable  to  pass  the  finger-tip  lightly  around  the  os  to  see 
how  much  it  opens  during  a  contraction,  how  well  the  bag  of  waters  forms,  and  how 
tense  the  membrane  becomes,  thus  forming  some  idea  of  the  strength  of  the  pains. 
After  this  the  fingers  rest  at  the  side  of  the  pelvis  until  the  pain  has  passed  away. 

Rectal  Examination. — To  avoid  frequent  vaginal  exploration,  with  its  inherent 
dangers,  rectal  exploration  may  be  substituted.  Done  gently,  with,  the  gloved 
index-finger,  the  rectum  will  not  be  injured  and  much  information  elicited.  With  a 
little  practice  it  is  possible  to  determine^  the  degree  of  engagement  of  the  head,  the; 
amount  of  dilatation  of  the  cervix,  and  ^yhether  or  not  the  cord  has  prolapsed. 
Often  position  may  be  made  out.     It  is  to  be  recommended. 

The  accoucheur  now  fills  out  his  history  sheet  or  card. 

The  Prognosis  of  the  Mechaiiism  of  Labor. — After  all  the  above  information  is 
obtained  tlie  various  points  arc  weighed  and  considered.  The  size  and  hardness  of 
the  child  are  balanced  against  the  size  of  the  pelvis,  and  both  comi)ared  with  the 
labor-pains — i.  e.,  the  power  of  the  engine  is  compared  with  the  work  it  has  to  do.

290  THE   HYGIENE   AND    CONDUCT    OF    LABOR 

An  opinion  is  hazarded  as  to  the  probable  mechanism,  and  possible  abnormalities 
of  the  same  studied  in  all  their  ])earings. 

For  his  first  200  cases  the  young  practitioner  liad  best  use  the  full  history 
sheet  reproduced  in  the  Appendix,  as  this  practice  will  best  develop  his  technic  and 
habits  of  carefulness  and  accuracy.  Later,  when  he  has  become  busy,  he  may  use 
the  cards  illustratetl  here  (Figs.  307  and  308),  reserving  the  extensive  history  sheet 
for  special  or  pathologic  cases. 

The  anxious  patient  will  now  put  two  questions  to  the  accoucheur.  One,  "Is 
everything  right?"  should  always  be  answered  in  the  affirmative,  with  a  word  of 
encouragement.  In  the  presence  of  an  anomaly,  the  husband  or  near  relative  must 
be  informed,  for  the  doctor's  o^^^l  protection,  but  the  parturient  should  be  spared 
the  alarm  mitil  it  is  needful  to  interfere,  when  the  conditions  are  to  be  gently,  kindly, 
and  \\ith.  great  tact  explained  to  her. 

The  second  query,  "How  long  will  it  last?"  should  be  answered  with  consum- 
mate care.  If  a  certain  hour  for  the  deliver}'  of  the  child  is  stated,  the  clock  will 
verj'  often  contradict  the  statement,  and  the  parturient  will  lose  faith  and  courage. 
The  ■\\Titer  usually  replies  that  the  length  of  the  labor  will  depend  on  the  strength 
and  frequency  of  the  pains,  but  that  everything  is  in  such  good  order  that  it  matters 
httle  whether  the  labor  lasts  a  little  longer  or  shorter  time. 

The  Attendance  of  the  Physician.— Ideally,  every  labor  case  should  be  con- 
tinuoush'  attended  by  a  physician  from  beginning  to  end.  The  author  enjoj's  this 
privilege,  having  the  interne  to  watch  his  hospital  cases  and  a  private  assistant  to 
stay  with  the  parturient,  in  his  home  practice.  How  great  the  advantages  of  such 
a  plan  are  and  how  comforting  the  practice  is  cannot  be  told.  It  midoubtedly 
saves  the  lives  of  many  mothers  and  children  and  it  certainly  prolongs  the  life  and 
usefulness  of  the  author.  If  the  accoucheur  must  leave  the  house,  he  does  so  only 
after  assuring  liimself  that  the  presentation  and  position  of  the  fetus  are  good,  that 
the  pelvis  and  child  are  normal,  that  the  cervix  is  dilating  naturally,  that  the 
mother  is  not  threatened  Avith  eclampsia,  that  abruptio  placentae  and  placenta 
prsevia  do  not  exist,  and  that  the  infant  is  in  perfect  condition.  The  nurse  is  to 
be  instructed  to  listen  to  the  child's  heart-tones  ever}"  hour,  and  to  report  at  once 
any  unusual  happening.  Only  accurate  observation  of  many  labors  will  give  the 
accoucheur  that  knowledge  which  will  enable  him  to  determine  if  it  is  safe  for  him 
to  leave  the  parturient, — and  when,  and  for  how  long, — and  even  with,  such  knowl- 
edge he  will  occasionalh^  return  to  find  the  child  delivered,  the  pains  having  sud- 
denly become  very  strong.  In  a  primipara  it  is  best  to  remain  in  the  house  after 
the  cervix  admits  three  fingers;  certainly  with  a  multipara;  and,  also,  if  the  pains 
are  very  strong  and  progress  rapid,  or  if  the  woman's  pre\aous  labors  have  been 
quick. 

When  the  physician  does  leave  the  case,  he  must  not  visit  infectious  diseases 
or  touch  pus  while  absent.  It  is  the  physician's  duty,  in  the  absence  of  a  trained 
nurse,  to  provide  sufficient  sterile  water,  towels,  sheets,  etc.,  as  well  as  to  have  in 
readiness  the  materials  for  an  aseptic  reception  of  the  infant. 


(•IlAPTi:ii  XXI 
THE  TREATMENT  OF  THE  FIRST  AND  SECOND  STAGES 

The  Inutincnt  of  the  Jir.st  stage  is  one  of  icalchful  expectaticy.  The  duty  of  the 
accoucheur  is  to  observe  the  efforts  of  nature,  not  to  aid,  until  she  ha.s  proven  herself 
unequal  to  the  ta.sk.  Only  when  nature  fails,  is  art  to  enter.  Nothing  is  .so  repre- 
hensible as  meddlesome  midwifery.  It  has  co.st  thousands  of  valuable  lives. 
Attempts  to  ha.sten  the  dilatation  of  the  cervix,  either  manually,  by  bags,  or  by 
having  the  woman  bear  down,  may  not  be  made.  Premature  bearing-down  effort.s 
of  the  mother  aid  very  little  in  the  first  stage,  and  tire  her  .so  that  she  ha.s  no  .'Strength 
left  for  the  expulsive  work  of  the  second  stage;  further,  it  is  distinctly  harmful, 
since  the  child  is  forced  down  before  the  os  is  dilated,  overstretching  the  broad  liga- 
ments and  laying  the  foundation  for  a  future  prolapsus  uteri.  Li't  the  ])arturient 
walk  around  the  room,  the  admission  of  dust  into  the  vagina  being  guarded  again.st 
by  a  large  sterile  pad  and  a  T-binder.  She  may  rest  at  intervals  on  a  couch,  lying 
on  her  back  or  on  the  side  to  which  the  occiput  is  directed, — for  example,  in  O.L.T. 
on  her  left  side.  This  is  to  favor  rotation.  Freciuent  external  examinations  may 
be  made  to  discover  the  progress  of  labor,  and  the  fetal  heart  tones  should  be  listened 
to  at  least  every  hour.  If  this  were  more  generally  practiced,  intrauterine  a.sphyxia 
would  be  more  often  discovered  early  and  more  children  saved  by  rapid  delivery. 
Eclampsia,  abruptio  placcntay.  rupture  of  the  uterus,  and  the  general  condition  of 
the  mother  must  also  be  in  the  mind  of  the  observant  accoucheur,  the  possibility  of 
the  former,  and  the  changes  in  the  latter  being  constantly  subject  for  thoughtful 
consideration.  Temperature,  pulse,  and  respiration  should  be  taken  and  recorded 
every  four  hours.  If  labor  is  protracted,  the  accoucheur  should  try  to  procure 
some  sleep  for  the  parturient.  Early  in  the  first  stage  morjihin  may  be  given, 
but  not  near  or  during  the  second  stage. 

Diet. — During  the  labor  the  woman  will  refuse  nourishment,  but  she  should  be 
pressed  to  take  liquids  in  order  to  preserv^e  her  strength  for  the  final  ordeal  of  de- 
livery and  the  third  stage.  This  is  imperative  where  the  labor  promises  to  be  pro- 
tractetl.  Postpartum  hemorrhage  is  more  formidable  in  a  weaki-ned  patient. 
Nausea  and  vomiting  are  occasionally  troublesome  and  medicines  have  little  effect 
on  them. 

The  Bowels. — Every  twelve  hours  the  lower  bowel  should  be  evacuated  by  a 
salt  solution  enema,  but  no  enema  should  be  given  if  the  delivery  seems  very  near, 
because  of  the  danger  of  a  flood  of  liquiil  feces  accompanying  the  birth  of  the  infant. 
If  feces  accumulate  in  the  rectum,  obstructing  deliver>',  an  enema  of  one  ounce 
of  Epsom  salts,  two  of  glycerin,  and  three  of  water  may  be  given.  During  lalwr 
both  physician  and  nurse  take  precautions  against  contaminating  the  vulva  with 
fecal  <liscliar^cs. 

The  bladder  shoukl  be  emptied  regularly  every  four  hours,  aided,  if  need  he, 
by  the  catheter.  If  filled,  it  forms  an  obstacle  to  delivery,  delays  rotation  and  pre- 
disposes to  incarceration  of  the  placenta  and  postpartum  hemorrhage  (Fig.  309). 

The  Rupture  of  the  Bag  of  Waters. — \\\\vn  the  accoucheur  judges  this  is 
imminent,  the  patient  is  jnit  to  bed,  lying  on  her  back.  After  it  htus  occurred,  the 
second  internal  examination  may  be  made.  The  author  does  not  always  examine 
if  the  heatl  is  engaged,  if  the  heart-tones  are  good,  and  labor  progressing  satisfac- 
torilv.     The  onlv  knowledge  to  be  gained  is  the  degree  of  dilatation  and  the  posi>ible

prolapse  of  the  cord.  If  required,  a  rectal  examination  may  be  made.  If  the  ex- 
ternal diagnosis  shows  a  posterior  position,  one  may,  durinii;  tlie  internal  examina- 
tion, make  a  tentative  effort  to  correct  it  b}'  combined  mani])ulation.  If  labor  is 
delayed  long  after  the  presumable  dilatation  of  the  cervix,  an  internal  examination 
is  made  to  discover  the  cause,  or  perhaps  to  rupture  the  obstructing  membranes. 
IMultiparae  often  have  very  rapid  deliveries  after  the  membranes  break,  wherefore 
it  is  advisable  to  l)egin  the  sterilization  of  tlie  hands  and  the  general  preparations 
for  the  delivery  earlier  than  in  primiparous  labors.

CONDUCT  OF  THE  SECOND  STAGE 

Bearing-down  pains  do  not  always  indicate  that  the  second  stage  is  begun,  nor 
does  the  rupture  of  the  Ijag  of  waters.  The  latter  may  occur  before  the  pains  start 
and,  again,  not  even  until  after  the  head  is  visible.  An  experienced  attendant,  from 
the  actions  of  the  parturient,  may  usually  decide  that  the  cervix  is  fully  dilated.  A 
few  particularly  sharp  pains,  attended  by  a  show  of  bright  blood,  usually  mchcate 
that  the  head  is  slipping  through  the  cervix.  The  bed  is  prepared  for  dehvers^  by 
being  dressed  with,  sterile  sheets,  the  patient  has  a  pair  of  sterile  leggings  or  hose 
and  a  sterile  night-gown  put  on;  the  table  carrying  the  solution  basins,  sterile  towels, 
sterile  tape,  and  scissors  for  cord  is  drawn  near  to  the  bed,  and  the  operator  prepares 
his  hands  and  puts  on  the  sterile  gown  and  gloves. 

The  patient  often  feels  as  if  the  bowels  are  to  move,  but  she  may  not  go  to  the 
closet;  the  movement,  if  any,  being  made  on  a  sterile  bed-pan.  More  often  the 
sensation  is  due  to  pressure  of  the  head  against  the  rectum.  Fecal  particles  that 
escape  during  the  pressing  efforts  must  be  carefully  gathered  in  sponges  ^^Tung 
out  of  1  :  l.')00  bichlorid,  and  the  anal  region  disinfected  with  the  same  solution. 
The  bladder  is  emptied  by  catheter  if  necessary. 

Four  main  points  are  to  be  considered  during  this  stage:  1.  Asepsis  and  anti- 
sepsis. 2.  Anesthesia.  3.  Protection  of  the  life  of  the  child.  4.  Preservation  of 
the  perineum.  Complications,  as  a})rupti()  placenta,  eclampsia,  ruptura  uteri, 
will  be  considered  under  their  respective  headings. 


THE    THKATMKXT    OK   THE    FIRST   ANT)    SECOND    STAGES  293 

Asepsis  and  antisepsis  luivc  hccii  considered  already,  and  will  be  touched  upon 
in  nearly  e\ery  j)liase  ol  liie  treatment  as  here  laid  down. 

Anesthesia. — Alter  much  experience,  the  author  has  come  to  dispense  with 
anesthetics  in  the  first  stage  of  labor,  except  in  unusual  instances.  A  cheerful, 
hnpefiil  demeanor,  sympathy  and  encouragement  from  the  physician,  will  usually 
help  the  woman  to  bear  the  pangs  of  labor  until  the  second  stage  is  about  to  begin. 
Suggestion,  to  a  certain  extent,  may  be  employed.  When  tlie  head  is  passing 
through  the  cervix  the  pain  is  inten.se,  and  here  a  few  whiffs  of  ether  are  very  helj)ful. 
During  the  .second  stage  the  author  gives  etluT  to  the  "obstetric  degree,"  and  as  the 
head  escapes  from  the  vulva,  the  jx'ricjd  of  greatest  anguish,  the  anesthetic  is  pushed 
to  the  "surgical  degree,"  Init  sto])i)e(l  as  soon  as  the  head  is  born,  the  patient  u.sually 
waking  up  a  few  moments  after  the  child  makes  its  first  cry. 

Women  vary  very  much  in  their  ability  to  stand  pain  and  in  their  demands  for 
anesthetics.  The  author  conducts  many  labors  without  any  narccjtic,  many  with 
}ust  a  few  deej)  inhalations  of  ether  as  the  head  is  born,  and  only  a  few  with  pro- 
long<Ml  anesthesia.  Ojierative  deliveries,  with  a  few  exceptions,  are  done  under 
surgical  anesthesia,  ))ut  perineorrha])hy,  cleaning  out  of  the  ut(Tus,  and  tamiionade 
are  as  often  done  without,  as  with,  narcosis. 

Two  degrees  of  anesthesia  have  been  mentioned.  Obstetric  anesthesia  is  the 
use  of  the  narcotic  only  to  dull  or  relieve  the  pain,  without,  or  with  only  a  very 
brief,  loss  of  consciousness.  Surgical  anesthesia  is  the  abolition  of  consciousness 
and  of  body  rigidity. 

Ohjcdions  to  Anesthetics — Chloroform  and  Ether. — 1.  Without  doubt  the  par- 
turient enjoys  a  slight  inununity  from  the  risks  of  surgical  anesthesia,  and  obstetric 
anesthesia  is  but  little  tlangerous.  It  is  not  true  that  deaths  have  not  occurred 
during  the  latter  form  of  administration,  but  they  are  rare,  and  other  conditions 
have  usually  ])een  present,  as  goiter  and  status  lymjihaticus.  Diseases  of  the  liver 
and  toxemia,  especially  of  the  hepatic  type,  contraindicate  all  anesthetics.  Chloro- 
form is  esp(K'ially  harmful  in  such  cases,  not  seldom  leading  to  acute  yellow  atrophy 
of  the  liver,  a  condition  which  closely  resembles,  if  it  is  not  identical  with,  "second- 
ary chloroform  death." 

2.  Anesthetics  weaken  the  uterine  contractions.  The  clinician  d(jes  not  need 
the  proof  brought  from  the  laboratory.  P^ven  under  the  obstetric  degre«'  the  pains 
aresometimcs  weakened,  are  further  apart,  and,  in  the  writer's  experience,  hemor- 
rhage in  the  third  stage  is  more  profuse, and  contractionandretractionoftheuterine 
nuisclc  often  delayed  or  insufficient.  Ether  acts  thus  to  a  nuich  less  degree.  On 
the  other  hand,  when  contractions  are  tuniultuous  or  irregular  and  too  acutely 
l)ainful,  or  when  the  woman  will  not  bear  down  in  the  second  stage  because  of  the 
pain  in  the  vulva,  an  anesthetic  will  often  calm  and  soothe,  thereby  actually  hasten- 
ing delivery. 

'.i.  The  anesthetic  nu\y  affect  the  child.  Ailministered  for  a  long  time,  as  was 
formerly  the  custom,  the  fetus  could  obtain  sufhcient  of  the  drug  to  be  seriously 
affected  by  it,  investigation  having  shown  that  tluTc  is  an  acute  albuminoid  de- 
generation of  its  vital  organs  during  the  first  days;  but  given  as  here  reconunenih'd, 
the  (hmger  to  the  child  is  very  slight. 

4.  Objections  on  the  score  of  religious  scruples,  that  j^ain  in  labor  is  "i)hysio- 
logic"  and  that  the  mother  will  not  love  her  child  born  without  jjain,  need  no 
connnent. 

5.  Anesthesia,  unless  deep,  in  rare  instances  excites  the  parturient  almost  to 
frenzy,  and  thus  ])laces  her  beyond  control  of  the  will  of  the  accoucheur.  If  her 
etTorts  are  needed  for  the  comj^leticm  of  the  delivery,  as  in  breech  ca.ses.  the  attend- 
ant finds  himself  in  a  dilennna.  Either  he  must  deliver  under  surgical  anesthe.'^ia 
or  wait  until  the  woman  gains  full  consciousness.  The  latter  course  is  recommended 
where  practicable. 


294  THE    HYGIENE    AND    CONDUCT   OF    LABOR 

Choice  of  Atiestheiic. — For  many  years  I  used  chloroform  exclusively  in  my 
obstetric  work,  because  it  was  quicker  in  action,  easier  to  carry,  pleasant er  to  take, 
and  seldom  caused  nausea  and  vomiting.  Its  bad  effect  on  the  pains  was  tolerated 
because  this  could  be  cared  for  satisfactorily.  One  secondary'  chloroform  death  in 
a  normal  case,  and  two  after  eclampsia,  caused  serious  question  in  my  mind,  and 
now  ether  is  used  except  in  rare  and  sj^ecial  instances  (see  Sippel).  Litti^,  after 
reporting  63  chloroform  deaths  (5  obstetric),  condemns  the  drug  unqualifiedly. 
Ether  is  slower  in  action,  more  is  required,  it  is  bulkier,  and  the  woman  often  vomits 
afterward;  but  it  has  proved  itself  safer  in  obstetrics,  as  it  has  in  surgery,  and, 
properly  administered,  one  can  obtain  very  satisfactory  results.  Chloroform  has  a 
serious  defect,  that,  in  the  i:)resence  of  an  open  flame,  it  is  decomposed  into  carbon}-} 
chlorid  and  hydrochloric  acid,  both  of  which  irritate  the  air-passages  of  all  in  the 
room,  making  the  attendants  cough  and  even  fatally  poisoning  them.  The  patient, 
too,  suffers  from  this,  and  perhaps  some  of  the  unexplained  puerperal  deaths  may 
thus  be  cleared  up.  Ether  is  to  be  used  where  it  is  necessary  to  operate  in  the 
presence  of  sepsis,  nephritis,  eclampsia,  cardiac  disease,  goiter,  or  uterine  atony. 
Ether  may  not  be  used  too  close  to  an  open  flame  because  of  the  danger  of  explosion, 
but  I  find  the  fear  of  this  accident  much  exaggerated. 

Indications. — 1.  Great  pain  at  the  end  of  the  first  stage  or  in  the  second  stage. 
2.  Great  excitability  at  these  periods.  3.  Tumultuous  pains  at  an}-  period  of  labor, 
especiall}^  if  the  cervLx  is  not  dilated  or  if  the  head  is  on  the  perineum,  the  idea 
being  to  moderate  the  power  of  the  uterus  and  to  save  it,  the  cervix,  or  the  peri- 
neum from  rupture.  4.  To  preserve  the  perineum  when  the  bearing-down  efforts 
are  too  strong.     5.  To  eliminate  the  inhibition  of  bearing  down  due  to  pain. 

Conditions. — (1)  Labor  must  be  sufficiently  advanced;  ether  is  ver}^  rarely 
given  in  the  first  stage,  best  in  the  second.  (2)  The  pains  must  be  strong  and 
regular,  so  as  to  offset  the  weakening  effect  of  the  drug.  (3)  When  given  simply 
for  the  relief  of  pain,  examination  of  the  patient  must  have  excluded  toxemia, 
hepatic  disease,  goiter,  hemophilia,  and  sepsis.  (4)  In  cases  of  severe  hemorrhage 
special  rules  apply. 

Method  of  Administration. — Obstetric  Degree. — Any  simple  inhaler,  or  even  a 
handkerchief  held  in  the  hand,  will  suffice.  The  open  method  is  preferred,  because 
in  obstetrics  the  carbonization  of  the  blood,  so  common  in  general  anesthesia,  must  be 
avoided  in  the  interests  of  the  child.  When  the  pains  begins,  15  drops  of  ether  are 
poured  on  the  mask,  and  the  patient  takes  deep  breaths  of  the  vapor;  as  the  pain 
increases  a  few  drops  more  are  given;  as  the  pain  subsides,  the  mask  is  removed. 
This  procedure  is  repeated  until  the  head  is  just  about  to  escape  from  the  vulva, 
when  the  ether  is  poured  on  frequently,  and  the  first  stage  of  surgical  anesthesia 
is  reached,  consciousness  is  abolished  for  a  few  minutes,  during  which  time  the 
infant  is  delivered. 

Deep  anesthesia  is  needed  in  obstetric  practice  under  the  same  conditions  as 
in  surgery,  to  produce  unconsciousness  to  pain  and  complete  relaxation.  It  is  to 
be  remembered  that  while  the  parturient  does  possess  some  immunity  from  its 
dangers,  this  safety  has  been  exaggerated,  and  confidence  in  it  has  led  to  the  care- 
less use  of  the  drug,  with  many  resulting  deaths.  If  the  reports  of  deaths  and 
collapse  during  anesthesia  in  midwifery  practice  continue  to  come  in  at  the  same  rate 
as  for  the  last  three  years,  it  will  soon  be  necessary  to  deny  that  the  parturient 
enjoys  any  immunities  from  the  dangers  of  narcosis.  Ether  is  said  to  reduce  the 
phagocytic  power  of  the  blood  ])y  its  fat-solvent  properties,  and  the  introduction 
of  fat  could  perhaps  restore  this  power. 

History. — Narcotic  potions  were  administered  by  the  ancients  in  labor.  Theocritus 
mentions  them  as  given  to  Antigone.  Other  examples  are  cited  by  Simpson.  Sir  .James  Y. 
Simp.son  was  the  first  to  use  ether  in  obstetric  practice  on  January  19,  1847.  He  did  a  version  and 
an  extraction.     In  November  of  the  same  year  he  discovered  the  anesthetic  properties  of  chloro-

form,  and  usofl  it  in  labor  cases  to  tlic  fxciu-sion  of  pther,  and  widoly  advocated  the  practice.  A 
storm  of  adverse  criticism  against  both  anesthetics  broke  loose,  at  h(jnie  and  abroad,  and,  to  our 
minds,  a  curious  anil  ridiculous  ptjlemic  was  waged  between  Simpson  and  his  opponents.  (See 
Obstetric  Memoirs,  Simpson,  vol.  ii,  Anesthetics.)  X.  ('.  Keep,  of  Boston,  was  the  first,  according 
to  ChanninK,  {^)  use  etiier  in  labor  in  .\merica — .Vpril  7.  1S17.  The  u.se  of  an  anesthetic  in  labor 
spread  (luickly,  jjarticularly  after  Victoria,  (^uet-n  of  Knglantl,  in  1.S.53  and  ISoT,  had  enjoyed  its 
benefits.      It  wits  called  the  (Queen's  chloroform,  or  aru.sllir.siii  a  In  nine. 

Other  A m/il/u-tics . — Regional  anesthesia,  invented  by  Corning,  and  elalx)rate<l  by  Bier  and 
TufTier,  the  cocainization  of  the  spinal  cord,  came  and,  fortunatelj-,  (juickly  went.  It  was  too 
dangerous,  heailache,  vcjmiting,  hyperpj'rexia,  tadiycardia,  mu.scular  spasms,  drug  into.xication, 
meningitis,  p«'rii)lieral  necroses,  being  the  evil  effects;  and,  further,  it  w;us  not  uniformly  efficient 
nor  the  effects  sufficiently  lasting.    Some  few  surgeons  still  employ  it,  using  novocain,  stovain,  or 

gantopon,  etc.  Recently  Stoeckel  advised  the  injection  of  the  cocain  into  the  .siicral  canal,  and 
ellheim,  cocainization  of  the  pudic  nerves,  reaching  them  through  vaginal  puncture.  Ixjcal 
anesthetics  have  been  employed,  as  cocain  and  belladonna,  to  the  cer\-ix,  the  perineum,  and  the 
rectum. 

Hypnotism  has  l)een  u-setl  in  hysteric  .subjects  with  reported  good  effects.  .Apfjllo  was  bom 
of  Latoiui  under  such  influence.  The  writer  frequently  u.ses  suggestion  during  labor  to  aid  the 
parturient  to  bear  the  pain,  and  after  labor  gentle  suggestion  will  aid  in  obtaining  the  quiet  and 
restful  sleep  .so  conducive  to  rapid  restoration  of  the  patient's  nerve  ecjuilibrium. 

Scopoldtnin-Morphin  Am.sllusia. — Schneiderlin,  a  neurologist,  in  1899  recommended  the 
employment  of  morphin  combined  with  scopolamin  for  the  production  of  surgical  anesthesia. 
Steinbiichel,  in  l'.KJ2,  first  recommended  its  use  in  labor,  and  now  ciuite  an  extensive  literature 
e.vists  on  the  .subject  (Hatcher).  Greene,  Xewell,  Haipeimy  and  Vrooman,  Ries  in  America, 
Kronig,  flau.ss,  Leopold,  Sir  J.  H.  Croom,  in  Europe,  and  others  have  employe<i  the  combination, 
with  conflicting  results.  My  own  experience  has  been  small  and  not  favorable.  By  administer- 
ing iJ(y  grain  of  scopolamin  and  3"6  grain  morphin  hypodermically,  the  parturient  is  put  into  a 
sort  of  "twiUgiit  sleep"  ('"Dammerschlaf  "),  from  which  she  is  easily  arou.sed,  but  after  which  she 
has  no  recollection  of  pain.  Occasionally  .slightly  larger  do.ses  are  requireil, — as  xItt  and  J4  of  the 
respective  drugs, — but  it  is  better  to  repeat  the  smaller  dose,  if  necessarj',  at  the  end  of  two  hours, 
and  then  less  morphin  is  given.  The  dangers  of  these  drugs  are:  (1)  Asphj-xia  and  narcosis  of  the 
child — two  of  my  cases  gave  me  considerable  difficulty  in  resuscitating  apparently  poi.soned 
children;  (2)  prolongation  of  the  lal)or  and  more  freqvient  necessity  of  forceps.  Others  report  a 
greater  number  of  postpartum  hemorrhages,  occasional  restless  delirium,  even  \-iolence,  and  un- 
certain results.  The  latest  writers,  Lequeu,  Avarff}',  Strassman,  excepting  Xewell,  condemn  the 
drugs  for  general  use  outside  of  hospitals,  where  the  parturient  cannot  bo  closely  watched.  Greene 
and  most  others  restrict  their  emploj-ment  to  nervous  and  unstable  primipane,  and  all  insist  on 
clo.sest  observation  of  both  patient.s — all  of  which  shows  that  the  remedy  is  not  applicable  to  the 
conditions  met  in  ordinary  olistetric  practice. 

Morphin  and  Chloral. — Morphin  is  frequently  tised  during  the  first  stage  of  labor,  alone  or 
combined  with  a  minute  dose  of  atropin,  to  calm  excessive  uterine  action,  to  soothe  the  patient,  or 
to  procure  needed  rest.  For  the  latter  purpose  it  may  be  supplemented  with  bromid  of  soda  per 
rectum.  Morphin  should  not  be  given  toward  the  end  of  the  first  stage  nor  in  the  .second  stage, 
because  experience  has  shown  tiuit  the  fetus  is  then  more  likely  to  be  narcotize<l  and  rendered 
incapable  of  establishing  respiration  after  delivery.  Chloral  should  be  very  sparingly  useil,  ita 
action  being  very  similar  to  that  of  chloroform,  and,  too,  it  irritates  the  kidneys. 

Xitrous  oxid  gas  mixed  with  oxygen  has  been  used  in  labor  at  intervals  since  1878.  It  is 
frequently  administereil  during  pregnancy,  and,  with  apparent  safety,  for  the  extraction  of  teeth. 
Its  exhibition  during  labor  has  not  become  generalized.  The  author  recommends  that  it  be  not 
used  to  introduce  ether  anesthesia  for  obstetric  operations,  since  the  inten.se  carbonization  of  the 
blood,  though  temporary,  might  injuriously  affect  the  child.  Several  cases  of  such  apparent 
action  have  occurred  in  the  author's  experience. 

Preservation  of  the  Life  of  the  Fetus. — An  ofTort  .'^hould  bp  made  to  reduce  the 
infant  mortality  timing  chiitl-l)irth.  The  author  i.s  con\'inced  that  attention  to  the 
child  during  the  second  stage  of  ordinary  labor  ^^^ll  result  in  a  greater  total  sa\nng 
of  life  than  the  application  of  all  tlie  newer  methods  of  operative  delivery — vaginal 
cesarean  section,  hebosteotomy,  and  the  extension  of  the  indications  for  cesarean 
.section  in  contracted  ])elvis.  All  honor  to  these  efforts!  l)ut  a  greater  and  richer 
field  lies  clo.se  at  hand  in  the  practice  of  every  ol)stetric  attendant.  A  continual 
watch  for  the  first  signs  of  asphj'xia  of  the  unborn  child,  and  for  the  syinjitoms  of 
abruption  of  the  j^laccnta  in  the  second  stage,  will  not  .seldom  be  rewartled  l)y  their 
discovery,  and  an  inunediate  delivery  will  save  the  life  of  the  fetus. 

For  the  i)tirpo.«<e  of  frequently  auscultating  tlie  fetal  heart,  during  the  .second 
stage,  the  jiatient  is  allowed  to  lie  on  her  back  imtil  the  perineum  is  well  di.stended, 
anil  then  turned  on  her  side  only  for  the  delivery,  if  the  accoucheur  prefers  deliver^' 
in  this  position.  The  author  delivers  most  women  on  the  back,  in  order  to  be 
able  to  hear  the  fetal  heart  more  satisfactorily. 


296  THE    HYGIENE   AND    COXDrCT   OF   LABOR 

Preservation  of  the  Perineum. — Anatomic  study  of  the  pelvic  floor  after  de- 
hvery  always  .shows  e\ideuces  of  injury  to  all  its  structures.  The  connective 
tissue  is  torn  in  many  places,  the  layers  of  fascia  are  loosened,  the  levator  ani 
muscle  lacerated  more  or  less;  the  urogenital  septum  is  always  rujitured,  the 
perineal  l)ody  frequently,  and  all  the  tissues  are  l^ruised,  showing  larger  or  smaller 
hemorrhages  and  suggillations.  The  later  results  of  these  macroscopic  and  micro- 
scopic injuries  are  shrinking  and  atrophy  of  the  pelvic  diaphragm,  relaxation  of 
same,  prolapse  of  the  urethra,  vagina,  bladder,  uterus — all  depending  on  the  extent 
of  the  traumatism.  In  imjiortance  these  lacerations  vary  very  much.  "Worst 
in  their  effects  are  the  tears  of  the  levator  ani,  the  perineal  ones  being  less  harmful, 
and  yet  it  is  the  prevention  of  perineal  lacerations  that  occupies  so  much  of  the 
accoucheur's  attention.  Our  best  efforts  are  to  be  directed  to  preserve  the  levator 
ani,  but  some  attention  should  be  given  to  the  perineum  itself,  because  it  has 
physiologic  and  jiathologic  dignitj-;  extensive  rupture  of  this  body  may  cause 
sterility,  vaginitis,  cervicitis,  endometritis  from  infection  ascending  through  the 
patulous  introitus;  a  perineal  tear  once  started  may  go  through  the  anus  into  the 
rectum,  causing  that  great  affliction — fecal  incontinence;  fresh  tears  may  form  the 
atria  of  bacterial  invasion;  the  structures  once  torn  can  never  be  perfectly  restored; 
finally,  the  injury  may  often  be  prevented,  and,  if  not  entirely,  it  may  be  limited  to 
a  safe  degree.  The  author  has  found  the  hymen  tears  in  all  cases;  60  per  cent,  of 
primiparse  have  tears  of  the  fourchet — the  so-called  first-degree  laceration;  25 
per  cent,  of  primiparse  and  10  per  cent,  of  multiparse  have  lacerations  extending 
■well  into  the  perineal  body,  and  in  10  per  cent,  the  injury  exposes  the  sphincter 
ani — the  so-called  second  degree.  Only  in  operative  cases  has  a  complete  lacera- 
tion— that  is,  through  the  sphincter  ani — occurred.  These  percentages  are  larger 
than  those  given  in  most  text-books,  the  reason  being  that  the  author,  after  the 
levator  ani  is  well  stretched,  allows  the  head  to  issue  rapidly,  with  a  view  to  sparing 
the  child's  brain  the  traumatism  of  a  prolonged  perineal  "protection."  Without 
doubt  children  suffer  brain  injuries  because  of  the  accoucheur's  anxiety  to  avoid 
perineal  lacerations.  The  excessively  slow  delivery,  too,  has  been  responsible  for 
cases  of  still-birth  from  asphyxia. 

Causation. — Rupture  of  the  perineum  may  not  always  be  prevented,  even  in 
the  best  hands  and  under  the  most  favoral^le  conditions.  The  pelvic  outlet  may  be 
diseased,  as  by  edema,  excessive  deposition  of  fat,  a  white-cell  infiltration  from 
S3^3hilis,  condylomata  lata  and  acuminata,  varicosities,  or  through  lack  of  elas- 
ticity from  scars,  from  previous  operation,  age,  or  constitution.  In  some  women 
otherA\dse  well  the  perineum  tears  like  wet  blotting-paper.  A  narrow  pubic  arch, 
b}'  forcing  the  head  back  into  the  perineum  and  not  allowing  the  occiput  to  crowd 
up  close  to  the  ligamentum  arcuatum,  favors  rupture.  A  vulva  situated  high 
on  the  pubis  is  subject  to  injury.  Necessity  for  rapid  delivery  often  makes  us 
disregard  the  perineum, ''as  in  breech  cases  and  when  the  child  is  threatened  with 
asphyxia.  Delivery  effected  early  in  labor  finds  the  perineum  unprepared  for  the 
rapid  dilatation.  Exit  of  the  head  in  unfavorable  attitudes— face,  brow",  forehead, 
and  in  posterior  rotation  of  the  occiput — frequently  causes  lacerations,  because  the 
most  favorable  circumferences  are  not  presented  to  the  canal.  A  large  child  acts 
in  the  same  way  by  overstretching  the  outlet. 

Treatment. — Prevention  of  perineal  lacerations  naturally  will  ]:)rocced  along 
lines  indicated  above.  Here  only  those  precautions  needful  in  spontaneous  labor 
will  be  described.  How  to  care  for  the  levator  ani  and  perineum  during  forceps 
and  other  operative  deliveries  will  be  given  in  full  in  the  proper  chapters. 

The  levator  ani  and  the  fascia  above  and  below  it,  making  up  the  pelvic  dia- 
phragm, canb(;  spared  serious  injury  only  by  slow^  dilatation.  While  carefully  watching 
the  fetal  heart -tones,  the  ])ati('nt  is  not  allowed  to  bear  down  overmucli  during  the  first 
part  of  the  second  stage.     The  author  does  not  hurry  this  period  of  labor  without

indic-ation.  If  the  pains  and  the  hearingHloun  (110118  are  tumultuous,  the  woman 
is  hiid  oil  iier  side  and  ctlier  given  iis  a  moderator.  While  more  fre(|uent  in  opera- 
tive deliveries,  the  tear  in  the  levat(jr  sometimes  oeeurs  at  the  point  of  its  attach- 
ment to  the  puhie  rami,  under  the  arch  of  the  pubis.  This  accident  may  rarely 
be  recop;nized  before  it  has  occurred,  but  if  it  is,  one  should  inci.se  the  muscle  in  the 
riglit  vaf;;inal  sulcus,  because  the  high  hidden  tear  may  be  impossible  to  .sew  up 
afterward,  but  the  lower  incision  is  accessible  to  the  needle. 

The  principles  of  the  pnjtection  of  the  perineum  are  two:  (1)  Deliver  slowly, 
developing  to  the  ultimate  the  ela.sticity  of  the  pelvic  floor;  (2)  deliver  the  hea<l  in 
forced  flexion,  to  ])re.sent  to  the  parturient  jiassage  the  smallest  circumferences  of 
the  head.  The  first  principle  needs  no  elucidation.  A  hard  body  which  has  to 
overc(jme  the  resistance  offered  by  an  ela.stic  cylinder  will  be  less  likely  to  tear  the 
cylinder  if  forced  through  it  very  slowly.  A  l)rief  study  of  the  mechanism  of  labor 
will  show  the  advantages  of  keeping  the  head  well  flexed  until  the  larger  part  of  it

the  accoucheur  does  not  interfere  by  word  or  act  until  the  scalp  is  visible  to  the

and  dowTiward  displacement  of  the  levator  ani.  \Mien  the  accoucheur  decides 
that  the  head  is  coming  through  too  fast,  he  asks  the  woman  to  cease  bearing  down, 
to  open  her  mouth  and  breathe  tlirough  it  until  the  forces  of  the  effort  is  expended. 

With  each  pain  the  head  is  allowed  to  come  down  to  distend  the  perinemn  a 
little  more.  If  the  pain  is  too  strong,  the  head  may  be  gently  held  back  by  evenly

as  it  docs  under  other  circumstances  of  opposition  to  its  powerful  action.  The 
author  has  seen  all  these  injuries. 

Not  seldom  feces  and  mucus  are  forced  from  the  anal  opening  during  the 
woman's  bearing-do^\^l  efforts.  Since  there  is  real  danger  of  infection  from  this 
source,  the  accoucheur  must  collect  such  discharges  in  large  cotton  sponges  soaked 
in  1 :  1500  bichlorid,  using  care  not  to  soil  his  glove  nor  the  region  around  the  anus. 
This  region,  as  an  additional  precaution,  is  rcsterilized  with  both  antiseptic  solu-

tions.     The  author  has  never  seen  any  harm  from  the  very  liberal  use  of  these 
antiseptics  on  the  vulva  and  perineum. 

In  gentle  fashion  the  head  is  permitted  to  descend  until  its  greatest  periphery 
stands  in  the  distended  vulva.  It  is  now  delivered  in  the  interval  between  pains. 
The  head  is  restrained  at  the  height  of  the  bearing-down  effort,  the  woman  is  asked 
to  breathe  through  her  mouth  or  to  cry  out,  while  the  accoucheur  tucks  the  clitoris 
and  labia  minora  behind  the  occiput  under  the  pubis.  If  the  patient,  in  the  de- 
lirium of  pain,  bears  down  violently,  ether  is  administered.      After  the  pain  has

ceased  tho  \v(^man  is  asked  to  bear  down,  and  during  this  effort  the  distended  per- 
ineum is  slipped  back  over  the  foreiiead  anil  face  under  the  ehin.  A  sterile  towel  is 
tucked  under  the  cliin  and  covers  the  anus,  which  i)revents  infection  of  the  ac- 
coucheur's hands  and  of  the  child's  mouth  by  feces. 

During  this  maiiceuver  the  head  is  maintained  in  a  state  of  flexion,  not  by 
pressure  on  the  forehead  through  the  perineum,  but  by  manipulation  of  the  part  that 
is  accessil)le  to  the  fingers.  A  gentle  attempt  to  lead  the  sul>occipital  regicjn  under 
the  pubis  is  first  made  by  ])ressing  the  head  back  onto  the  perineum  with  the  finger 
on  the  occipital  protuberance,  during  two  or  three  pains.  When  the  head  has 
descended  far  enough  to  give  hold  to  the  fingers,  these  applied  right  at  the  edge  of 
the  frenulum  are  used  to  press  it  up  under  the  arch  of  the  pubis,  and,  as  the  head

finally  rolls  up  onto  the  pul)is,  the  flexion  is  maintained,  as  far  as  possible,  by 
making  pressure  on  the  part  delivered  against  the  l)one  (Figs.  313  and  310). 

As  soon  as  the  face  is  delivered  the  forehead  and  eyelids  are  wiped  with  a  gauze 
sponge  \vrung  dry  out  of  1:1500  bichlorid  solution,  the  mucus  is  squeezed  out  of 
the  nostrils  and  Nuped  out  of  the  mouth  with  the  finger,  covered,  if  need  be,  with  a 
piece  of  soft  linen  or  lintine.  These  details  are  important.  Removal  of  the 
vaginal  secretions  from  the  neighborhood  of  the  eyes  is  to  prevent  ophthalmia 
neonatorum;  the  removal  of  mucus  from  the  nose  and  mouth,  to  prevent  aspiration 
of  the  foreign  matter,  ^^^th  subsequent  intestinal  sepsis,  atelectasis,  and  bronrho- 
pneumonia. 

The  accoucheur  now  feels  for  the  cord  and  notes  if  it  is  around  the  neck,  and  if 


304 


THE   HYGIENE   AND    CONDUCT   OF    LABOR 


it  is  tight,  making  an  obstacle  to  delivery.  If  it  does  this,  it  should  be  clamped  and 
cut.  A  cord  that  is  too  short,  or  relatively  too  short,  may,  unless  cut,  pull  on  the 
placenta  and  cause  anomalies  in  the  third  stage,  or  even  inversion  of  the  uterus. 
If  the  patient  has  been  lying  on  her  side,  she  is  now  gently  turned  onto  the  back 
for  the  delivery  of  the  trunk.  This  procedure  brings  the  upper  limb  over  the  edge 
of  the  bed,  and  it  may  be  allowed  to  rest  on  a  chair,  which  leaves  the  patient  in  the 
oblique  position,  Anth  the  vulva  near  the  side  of  the  bed,  and  very  favorably  placed 
for  dehvery  of  the  shoulders  (Fig.  319).  If  preferred,  the  patient  may  be  moved 
over  to  the  middle,  with  both  legs  resting  in  the  bed,  or  put  across  the  bed. 

Delivery  of  the  Shoulders. — A  tendency  to  hurry  this  part  of  labor  should  l)e 
resisted.  If  the  child's  face  is  normally  blue  and  reacts  to  stimuli,  e.  g.,  rubbing, 
one  mav  wait  for  the  renewed  action  of  the  uterus.     After  a  minute  or  two  another

pain  comes  on  and  the  i)atient  gently  bears  down  until  the  anterior  shoulder  be- 
comes visible  just  behind  the  pubis.  Now  the  accoucheur  lifts  the  child  up  and 
brings  the  posterior  shoulder  over  the  perineum.  If  the  child's  hand  is  accessible, 
the  arm  is  drawn  out  gently.  Then  the  child  is  depressed  as  the  anterior  shoulder 
comes  from  behind  the  pubis,  and  now  the  rest  of  the  body  follows  in  one  long  pain 
without  particular  mechanism.  The  child  must  not  be  dragged  out  of  the  uterus. 
It  is  best  if  the  natural  powers  force  it  out,  the  physician  aiding  the  process  only  by 
directing  the  mechanism,  as  above  indicated.  A  perineum  may  be  torn  by  the 
shoulders  or  a  slight  tear  plowed  deeply  by  them,  and  the  clavicles  may  be  broken, 
or  the  nerves  and  muscles  of  the  neck  overstretched  at  this  stage  of  the  delivery 
unless  proper  care  be  exercised. 

If  the  delivery  of  the  shoulders  is  delayed  too  long,  the  woman  is  asked  to  bear 
down,  failing  which  the  hand  on  the  belly  performs  Kristeller's  expression,  or  the

normal  cases.  The  author  advises  such  interference  only  in  i)atholoKic  cases,  and  as  a  preparation 
for  a  rapid  breech  or  iorcrpn  extraction.  \'ariou.s  instruments  were  design*-*!  to  lift  tlie  head 
away  from  the  perineum,  one  of  the  most  curious  being  a  perineal  horn,  like  one  u.sed  for  jiutting 
on  shoes. 

Soranus  of  Kphesus  (about  110  a.  d.)  first  attempted  to  "support"  the  perineum  with  the 
hand,  a  notion  that  it  ha.s  been  impo.s.sible  to  eradicate  from  the  me<Jical  mind.  ClfXHlell  tri«Hl  to 
"relax  the  i)erineum"  by  pres.sure  fnjm  the  two  sides  toward  the  middle  line.  Various  attempts 
have  been  ma<le  by  .some  accoucheurs  to  lift  the  perineum  forward  with  fingers  intr<j<luce<l  into  the 
anus,  or  by  the  hand  placed  on  the  perineum  from  the  outside.  Others  try  to  strip  the  vulva  back 
over  the  head — all  manteuvers  whicli  fail  in  their  object,  areliarmful  l)«'rau.se  of  injury  to  the  levator 
ani  and  rectum,  and  dangerous  becau.se  of  sei)sis.  Finally,  may  be  nu-ntioned  the  employment  of 
incisions  in  the  perineum  to  avoid  deeper  tears  of  the  structure. 

Episiotomy. — When  a  tear  of  the  perineum  appears  inevitable,  the  question 
arises,  shall  it  be  allowed  to  occur  spontaneously  and  go  in  whatever  direction  it 
may,  or  shall  we  .seek  to  anticipate  it,  or  at  least 
divert  it  away  from  the  sj)liinct(T  into  unimportant 
structures?  Ould,  in  1742,  cut  the  vulvar  outlet 
when  it  offered  too  great  resistance  to  the  escape 
of  the  head.  G.  P.  MichaeHs,  in  1810,  incised  the 
perineum  to  avoid  a  dangerous  tear.  Ritgen  and 
Schultze  made  numerous  small  incisions  in  the 
tense  vulvar  ring.  Scanzoni  recommended  two 
lateral  incisions,  Crede,  one,  directed  from  the 
frenulum  toward  the  tuberosity.  Man}-  accou- 
cheurs perform  the  operation,  preferring  a  clean 
cut  to  the  jagged  tear,  and  claiming  that  the 
lateral  structures  are  less  important  than  the  cen- 
tral portion  of  the  perineum,  and  fearing  that  a 
tear  beginning  in  the  middle  line  only  too  easily 
goes  beyond  control  of  the  attendant  into  the 
sphincter  ani,  even  into  the  rectum.  Episiotomy 
is  the  name  applied  to  the  operation,  which  might 
more  correctly  be  considered  under  the  heading  of 
operative  obstetrics,  but,  owing  to  its  frequency, 
^Nill  be  described  here.  The  incision  is  made  in 
tliree  ways — the  lateral  or  bilateral  (Fig.  322), 
where  the  cut  is  parallel  with  the  long  axis  of  the 
mother's  person;  the  median,  where  tlie  line  lies  in 
the  raphe  (a  method  recently  again  urged  by 
Kiistner)  and  the  mediolateral,  reconanended  by 
Tarnier  and  practised  by  the  author.    One  must  be 

sure  that  he  understands  what  is  expected  of  eijisiotomy.  It  simply  cuts  the  skin,  the 
urogenital  septinn,  with  the  constrictor  cumii  and  transversus  perinei,  and  a  few  of 
the  anterior  fil)ers  of  the  j)uborectal  portion  of  the  levator  ani.  Diihrssen,  in 
1888,  recommended  a  tleeper  ej)isiotomy  or  perineotomy  for  pathologic  ca.st\s,  in 
which  the  incision  went  through  the  levator  ani  into  the  ischiorectal  fossa.  There 
are  special  indications  for  this  extensive  operation,  and  it  is  performed  only  when 
delivery  must  be  effected  before  the  levator  has  had  time  to  stretch  even  a  little. 

The  indications  for  the  u.sual  episiotomy  are:   Resistant   jXTineum,  causing 
tlelay  in  the  e.xit  of  the  head  through  the  vulva;  some  j)ath<ilogic  condition  of  the

may  not  give  the  perineum  time  to  dilate,  and  when  one  sees  that  the  perineum  will 
surely  tear,  to  divert  the  laceration  away  from  the  anus.

It  is  be.st  to  wait  until  the  head  has  stretched  the  levator  ani  well  (which  is 
determined  by  the  opening  of  the  anus  and  the  dislocation  of  the  anus  downward 
and  forward),  and  only  the  resistance  of  the  vulvar  outlet  remains  to  be  overcome. 


THE   TREATMENT   OF   THE    FIRST   AND    SECOND    STAGES  307 

If  at  this  point,  by  vaginal  inspection  or  palpation,  one  discovers  the  beginning  of 
a  tear,  it  is  anticipated  by  episi()t()ni3\  One  blade  of  the  scissors  is  laid  on  the 
vaginal  mucous  membrane,  the  otiier  rests  on  the  skin  of  the  perineal  body,  mid- 
way between  the  anus  and  the  tuberosity  of  the  ischium,  the  cutting  angle  of  the 
scissors  being  at  the  median  raphe  (Fig.  323).  With  the  finger  and  thumb  of  the 
other  hand  tlic  sphincter  is  j^rcssed  out  of  the  bite  of  the  scisscjrs.  The  patient  i.s 
given  a  few  e.\tra-decp  iiilialations  of  ether,  and  with  a  single  fjuick  UKjtion  the  tis.sues 
are  severed.  Hemorrhage  is  stopped  bj'  pressure.  Usually  the  head  issues  quickly 
after  the  incision  is  made,  and  then  the  bleeding  ceases,  but  if  it  does  not,  a  firm 
tampon  will  check  it  until  the  sutures  are  appliccj.  The  imision  is  re[)aired  after 
delivery  of  the  placenta,  in  the  manner  usual  with  ijcriucorriiaphies  (p.  730j. 


THE  CARE  OF  THE  CHILD 

A  warm  sterile  receiver  is  ready  for  the  new-born  individual,  who,  as  soon  as 
born,  is  placed  near  the  vulva,  so  that  the  cord  is  not  tiragged  upon,  yet  far  enough 
away  so  that  he  is  not  soiled  with  the  l)lood,  feces,  etc.,  about  the  anus,  and  aLso 
safe  from  compression  by  the  mother's  person. 

The  first  attention  to  the  child  is  the  \viping  of  the  face  and  eyelids  with  a 
sponge  squeezed  dry  from  a  1:1.500  liichlorid  soluti(jn,  and  rem<nal  of  the  mucus 
from  the  air-jxissages  immediately  after  tiie  head  is  l^orn — points  already  men- 
tioned. 

Tying  the  Cord.— After  waiting  until  the  pulsation  in  the  exposed  umbilical 
cord  has  perceptibly  weakened  or  disappeared,  the  child  is  severed  from  its  mother. 
Until  the  cord  is  severed  the  child  is  still  a  part  of  its  mother  and  has  no  legal  exist- 
ence. With  a  piece  of  linen  bol)l)in,  coarse  silk,  rubl)er  band,  or  any  strong  string 
the  cord  is  ligated  close  to  the  skin  margin  of  the  navel  i}/?  inch),  first  being  sure 
that  there  is  no  umbilical  hernia  which  might  allow  a  loop  of  gut  to  be  caught  in  the 
grasp  of  the  ligature.  Anotiier  ligature  is  placed  a  few  inches  from  the  first,  and, 
protecting  the  child  from  injury,  the  cord  is  severed  with  sterile,  dull,  and  blunt 
scissors  close  to  the  first  ligature.  It  is  important  to  leave  as  little  as  possible  of  the 
cord  to  be  cast  off,  and,  further,  a  short  stump  is  less  Ukely  to  be  dragged  upon  and 
easier  to  dress.  The  short  stump  method  was  practised  by  Mauriceau  and  only 
recently  revived.  The  first  tying  must  be  made  very  secure,  and  security  is  ol>- 
tained  by  tightening  the  knot  slowly  and  interruptedly,  giving  time  for  the  jelly  of 
Wharton  to  escape  from  mider  the  thread,  which  thus  comes  to  constrict  only  the 
vessels. 

During  the  four  or  eight  minutes  while  waiting  to  tie  the  cord  the  child  obtains 
from  40  to  00  gm.  of  the  reserve  l)loo(l  of  tlu'  placenta — a  fact  which  was  first  slumii 
by  Budin.  The  blood  is  pressed  into  the  child  by  the  uterine  contractions,  iiiul  part 
is  aspirated  by  the  expanding  chest.  This  extra  blootl  the  child  needs  in  its  first 
days  of  life,  and  observation  has  shown  that  such  children  lose  less  in  weight  and 
are  less  subject  to  disease.  It  is  an  error,  on  the  other  hand,  to  force  the  bloo<l  of 
the  placenta  into  the  child  by  stripjiing  the  cord  toward  the  child.  This  overloads 
its  blood-vessels,  causes  icterus,  melena,  even  apoplexy.  The  child  never  had  the 
extra  blood  of  the  placenta.  The  practice  of  waiting  until  the  placenta  is  delivered 
before  tying  the  cord  is  not  recommended. 

A  second  ligature  is  applied  to  the  cord  to  ke(>p  the  blood  in  the  jilacenta  iuid 
give  the  uterus  a  firm  body  to  act  on,  to  prevent  the  soiling  of  the  bed  and  patient 
with  blood  which  would  flow  from  the  open  vessels,  and  to  preserve  a  possible  tuin, 
still  in  the  uterus,  from  hemorrhage,  since  the  two  circulations  of  twins  usually 
anastomose. 

The  stumji  and  the  region  of  the  belly  around  it  are  now  wiped  with  1  :  l.')00 
bichlorid  or  pure  alcohol,  a  piece  of  dry  gauze  laid  over  the  wound,  and  the  infant,

wrapped  in  a  sterile  receiver,  is  handed  to  the  nurse,  who  ])uts  it  in  a  safe,  warm 
place,  delt'iiatinu;  a  relative  to  watch  it  and  see  that  it  breathes  naturally. 

The  Care  of  the  Eyes. — ]\Iany  States  have  passed  legislation  making  the  anti- 
septic treatment  of  the  eyes  of  the  new-born  obligatory  on  the  part  of  the  accoucheur. 
Statistics  prove  that  about  33  per  cent,  of  the  cases  of  blindness  admitted  to  the 
institutions  sup]:)orted  by  the  State  have  lost  the  light  of  day  through  the  lack  of 
proper  jjrecaution  at  the  time  of  ])irth.  The  blindness  is  caused  by  a  disease  known 
as  ophthalmia  neonatorum,  which  is  a  purulent  inflammation  of  the  conjunctiva 
and  cornea,  clue,  nine  times  out  of  ten,  to  the  gonococcus  of  Neisser,  The  disease  is 
highly  preventable,  and,  even  in  eleemosynary  lying-in  hospitals,  receiving  large 
numbers  of  patients  with  gonorrheal  vaginitis,  it  has  been  almost  eradicated.  The 
germs  get  into  the  eyes  during  the  passage  of  the  head  through  the  vagina,  or  are 
washed  into  them  b}^  the  attendant,  or  wiped  into  them  by  the  mother.  While 
the  gonococcus  is  usuallj^  causative,  the  pneumococcus,  the  bacillus  of  diphtheria, 
and  other  germs  may  cause  serious  conjunctivitis.  The  child  maj'  be  born  with  the 
disease  already  well  advanced. 

Mode  of  Prevention. — If  the  husljand  or  wife  is  known  to  have  gonorrhea,  the 
vaginal  inflammation  is  to  be  treated  during  pregnancy  b}'  the  usual  methods. 
Douches  of  1 :  1500  potassium  permanganate,  given  under  low  pressure,  and  applica- 
tions of  25  per  cent,  argyrol  tampons  give  good  results.  During  labor  the  vagina- is 
douched  out  every  six  hours  with  1  per  cent,  lysol  solution^ — this  only  in  cases  of  gonor- 
rhea, not  for  the  routine  delivery.  The  bag  of  waters  must  not  be  ruptured,  but  is  to 
be  allowed  to  come  down  and  line  the  vagina  for  the  passage  of  the  head.  It  is  best 
if  the  child  of  such  a  mother  is  delivered  with  a  caul.  During  all  vaginal  examina- 
tions the  eyes  of  the  fetus  (for  example,  in  face  presentation)  must  not  be  touched. 
When  there  is  a  purulent  greenish  vaginal  discharge,  or  if  there  are  condylomata  on 
the  vulva,  the  precautions  are  redoubled,  the  aim  being  to  prevent  all  possibility  of 
maternal  secretions  getting  into  the  conjunctival  sac.  The  same  principle  is  carried 
out  after  the  head  is  born,  the  vaginal  mucus  being  removed  at  once  from  the  neigh- 
borhood of  the  eyes  with  pledgets  A\Tung  dry  from  1  :1500  bichlorid,  and  great  care 
observetl  to  allow  no  reinfection. 

The  nurse  is  instructed  always  to  observe  this  same  care  while  giving  baths, 
and  the  first  cleansing  is  best  made  by  an  albolene  or  lard  rub,  to  remove  the 
vernix  caseosa.  When  gonorrhea  is  present,  oil  rubs  are  substituted  for  the  baths 
entirely.  In  maternity  practice  the  child  and  its  mother  are  rigidly  isolated,  because 
the  disease  is  highly  infectious. 

Active  antisepsis  of  the  eyes  may  not  be  needed  if  the  above  method  is  prac- 
tised, but  it  is  best  to  disinfect  the  eyes  as  an  additional  precaution.  Where  gon- 
orrhea is  suspected  in  either  parent,  the  old  Crede  method  is  used — a  drop  of  2 
per  cent,  silver  nitrate  solution  in  each  eye,  neutralized  immediately  with  salt 
solution. 

As  a  routine,  in  hospital  practice,  the  author  uses  1  per  cent,  nitrate  of  silver 
solution  and  does  not  neutralize  it,  a  practice  also  in  vogue  in  the  New  York 
Lying-in  Hospital,  the  University  of  Pennsylvania  Maternity,  and  the  Manhattan 
Maternity.  The  Johns  Hopkins  Maternity  uses  the  2  per  cent,  solution.  In  his 
private  practice  the  author  invariably  employs  some  antiseptic,  and  at  present  uses 
25  per  cent,  argyrol  solution  with  satisfactory  results. 

Other  antiseptics  have  been  recommended,  as  bichlorid,  boric  acid  (useless), 
acetate  of  silver,  sophol,  etc.,  but  the  author  has  found  no  reason  to  alter  theprac- 
tice  outlined  aljove. 

Some  practitioners  use  the  drops  imm-ediately  after  the  child  is  born,  but  the 
author  prefers  to  wait  until  after  the  third  stage  is  completed,  so  that  he  can  do  the 
Uttle  operation  himself,  under  favora])le  conditions.  Thus  is  assurance  obtained 
that  the  medicine  actually  reaches  the  conjunctival  sac. 


THE   TREATMENT   OF   THE    FIRST   AND    SECOND    STAGES  309 

No  objections  may  be  urgetl  against  this  prophylactic  antiseptic  treatment  of 
the  eyes.  Statistics  prove  conclusively  that  it  reduces  the  frequency  of  i)urulent 
conjunctivitis  to  less  than  y>oi  I  per  cent.  In  the  Chicago  Lying-in  Hospital  only 
one  child  in  the  last  1000  cases  developed  the  di.sease,  and  this  was  verj'  mild.  The 
frequency  of  "silver  catarrh"  under  the  old  Crede  method  has  been  reduced  by  the 
u.se  of  a  1  per  cent.,  instead  of  a  2  per  cent.,  .solution,  and  with  tiie  2')  jxr  cent, 
argyrol  .solution  such  slight  catarrhal  reactions  are  very  rare  and  are  easily  cured. 
The  silver  .solution  mu.st  Ix'  matle  fresh  nearly  every  day,  as  it  is  the  decomi)Osition 
products  which  cau.se  the  conjunctival  irritation. 

The  writer  is  not  certain  that  a  child  would  not  be  able  to  recover  damages  at 
law  from  the  accoucheur  if  it  should  l)e  blinded  at  birth  an^l  it  were  proved  that  the 
attendant  did  not  use  the  recognized  precautions.

■      CHAPTER  XXII 
THE  THIRD  STAGE 

IMoRE  women  die  from  accidents  of  the  third  stage  of  labor  than  during  the 
other  two  combined.  On  a  proper  conduct  of  this  part  of  the  delivery  depend  the 
woman's  freedom  from  postpartum  hemorrhage,  the  expulsion  of  the  secundines 
complete,  the  smooth  convalescence  during  the  puerperium,  and  even  her  health 
later  in  life.  Postpartum  hemorrhage  may  be  directly  fatal,  or  may  leave  the 
woman  permanently  invalided;  retention  of  pieces  of  placenta  may  be  the  cause  of 
puerperal  infections  and  lay  the  foundation  for  ineradicable  disease.  It  is  impor- 
tant, therefore,  that  the  accoucheur  be  familiar  with  the  physiology  of  the  third 
stage,  and  possess  a  good  technic  in  its  conduct.  Baudelocque  distinguished  the 
separation  from  the  expulsion  of  the  after-birth,  and  this  difference  must  always  be 
kept  in  mind.  The  same  general  principle  applies  to  the  treatment  of  this  stage  as 
to  the  others,  the  accoucheur  studies  the  mechanism  as  it  unrolls  under  hand  and 
eye,  watches  the  patient,  and  interferes  only  for  good  reason. 

Mode  of  Conduct. — As  the  child  leaves  the  vagina  the  nurse  or  the  assistant 
follows  clown  the  receding  uterus  "vvdth  the  hand  placed  lightly  upon  it.  After 
delivery  the  accoucheur  himself  guards  the  uterus  through  a  sterile  towel.  No 
massage  of  the  fundus  is  practised:  the  hand  simply  rests  on  it,  noting  its  firmness 
and  the  varying  consistence,  clue  to  contraction  and  relaxation.  When  the  child  has 
been  severed  from  the  mother,  the  accoucheur  resumes  his  watch  over  the  uterus, 
a  warm,  clean,  folded  sheet  is  laid  under  the  patient,  a  sterile  basin  or  bed-pan  is 
pushed  against  the  nates  and  perineum,  taking  care  not  to  push  feces  upward  onto 
the  vulva,  and  the  cord  is  drawn  up  over  the  thigh,  leaving  a  loop  hanging  so  that 
it  just  touches  the  bottom  of  the  basin  (Fig.  325).  The  woman  lies  on  her  back, 
■wdth  the  legs  drawm  up  or  outstretched,  according  to  her  comfort.  The  abdomen  is 
covered,  but  the  basin  must  be  visible,  for  the  accoucheur  wishes  to  see  if  blood 
accumulates  in  it.  If  the  woman  has  been  delivered  on  the  side,  she  is  gently  turned 
on  her  back  for  the  conduct  of  the  third  stage,  taking  care  to  be  certain  that  the 
legs  are  pressed  firmly  together,  and  that  the  uterus  is  very  hard  during  the  move- 
ment— these  precautions  to  avoid  air-embolism,  which  has  occurred  (Braun). 

The  accoucheur  now  sits  or  stands  at  the  side  of  the  patient  (Fig.  325),  and 
studies  the  phenomena  of  the  separation  of  the  placenta,  and,  in  the  absence  of 
hemorrhage  from  the  vulva  or  into  the  uterus,  has  nothing  else  to  do  for  fifteen  to 
thirty  minutes.  The  hand  on  the  uterus  notes  the  frequency  and  strength  of  the 
after-pains;  the  eye  notes  the  amount  of  blood  accumulating  in  the  Imsin.  If  the 
uterus  remains  firm  and  does  not  balloon  out  with  blood;  if  there  is  no  external 
bleeding — nothing  is  done,  but  if  the  uterus  softens  and  fills  up,  or  if  there  is  exter- 
nal hemorrhage,  a  gentle  massage  is  practised.  The  four  fingers  make  circles  on  the 
posterior  wall  of  the  fundus,  while  the  thumb  rests  in  front,  the  motion  resembling 
the  kneading  of  bread.  As  soon  as  the  uterus  becomes  firm  the  oozing  will  cease 
and  the  kneading  may  be  discontinued.  Inspection  of  the  vulva  will  show  whether 
the  hemorrhage  comes  from  some  tear  of  the  vulva  or  clitoris  or  from  a  point  higher 
up  in  the  parturient  canal.  In  pathologic  cases  abnormalities  of  the  separation  of 
the  placenta  cause  hemorrhage,  and  then  the  treatment  of  the  third  stage  has  to  be 
altered.  (See  p.  775.)  The  accoucheur  waits  for  the  signs  that  the  placenta  has 
been  separated  and  has  been  expelled  from  the  uterus  into  the  dilated  lower  uterine 

310 


THE   THIRD    STAGE

segment  and  upper  vagina.  Strong  uterine  contractions  themselves  would  indi- 
cate this  to  the  accoucheur,  Imt  there  are  other  signs:  (1)  The  cord  becomes  Hmp 
and  advances  3  or  4  inches  from  the  vulva  (diagnosed  by  observing  tiic  longer  loop 
in  the  basin) ;  (2)  the  uterus  rises  up  in  the  abdomen,  usually  to  the  right  side,  while 
below,  over  the  pubis,  a  soft,  boggy  mass  appears  (the  placenta);  (3)  the  globular 
uterus  has  flattened  out  from  before  backward,  presents  a  sharp  ridge  at  the  fundus, 
is  more  movable,  smaller,  and  harder;  (4)  a  flat  dimple  is  j)alpable  on  the  fundus. 

These  phenomena  are  apparent  in  ten  to  forty-live  minutes,  depending  on  the 
strengtii  of  the  uterine  c(jntractions.  When  the  placenta  is  surely  out  of  the  cavity 
of  the  uterus,  there  is  no  real  need  of  waiting  longer  for  its  delivery;  indeed,  the 
author  believes  that  it  is  better  practice  to  remove  it  at  this  time,  because  there  is 


Fio.  325. — Gtardino  Utkui-s  Postpakti-m. 
To  show  exact  position  of  the  band,  the  sterile  towol  was  removed. 

less  likelihood  of  blood-clots  forming  in  the  partially  emjitied  parturient  canal. 
On  the  average,  twenty  to  twenty-five  minutes  elapse  before  the  placenta  is  fully 
separated. 

Now  the  attendant  assures  himself  of  three  thing.s — that  the  bladder  is  empty 
(catheterize,  if  necessary);  that  the  uterus  is  in  firm  contraction  (wait  for  an  after- 
pain);  that  the  uterus  is  in  the  median  line  (bring  it  there  by  pressun*  from  the 
sides).  The  woman  is  asked  to  bear  down,  to  see  first  if  she  can  exjx'l  the  ])lacenta 
herself.  If  she  cannot,  the  uterus  is  grasped  in  the  whole  hand  with  the  thumb 
in  front  (Fig.  326)  and  gently  jiushed  without  squeezing  down  onto  the  placenta,  in 
the  axis  of  the  inlet.  The  uterus  is  used  simply  as  a  piston,  as  a  body  through 
which  to  exert  jjressure  on  the  ]>lacenta  lying  in  the  vagina,  and  this  manopuver  is 
calleil  "early  expression" — "early,"  l)ecause  it  anticipates  nature's  exi)ulsion.     As 


312 


THE  HYGIENE  AND  CONDUCT  OF  LABOR 


the  placenta  distends  the  vulva  the  woman  usually  bears  down  and  expels  it  into 
the  basin,  into  which  it  should  be  allowed  to  fall,  dragging  the  membranes  after  it. 
It  is  best  to  allow  the  membranes  to  come  out  of  their  own  weight,  but  if  they 
should  be  adherent  (evidenced  by  the  placenta  not  falling  into  the  basin),  gentle, 
steady  traction  is  made  on  them  without  twisting.  One  grasps  the  meml^ranes 
near  the  vulva  from  above,  to  avoid  contact  ^\'ith  the  suspected  perineal  and  anal 
regions.  If  the  membranes  start  to  tear,  greater  gentleness  is  to  be  used,  and  if 
they  should  break  off,  the  proximal  end  should  be  grasped  with  an  arterj'  forceps. 
Five  minutes'  time  may  be  required  to  remove  the  secundines  in  an  intact  condi- 
tion. Now  the  uterus  is  given  a  brisk  massage,  and  the  patient,  one  dram  of  ergot. 
This  is  not  always  necessary,  but  the  author  has  never  seen  any  harm  from  its  use,

Uterus  is  used  only  as  a  medium  to  exert  pressure  on  placenta. 


and  often  felt  that  the  uterus  got  harder  and  remained  so  more  continuously  when 
it  was  administered.     Ergot  is  never  given  before  the  placenta  is  delivered. 

If  the  first  "early  expression"  does  not  bring  the  after-birth,  a  mistake  has 
been  made  as  to  the  placental  separation,  and  the  attendant  waits  for  more  definite 
signs  to  appear,  when  the  simple  expression  is  repeated.  Unless  the  woman  bleeds, 
there  is  no  danger,  and  one  may  safeh'  wait  even  eight  or  ten  hours.  If,  after  one 
hour,  during  which  time  two,  or  at  most  three,  simple  expressions  have  been 
attempted,  the  placenta  fails  to  come,  a  Crede  expression  is  performed,  since  the 
third  stage  is  pathologic.  Crede's  expression  differs  from  the  simple  form  in  that 
the  uterus,  at  the  same  time  that  it  is  forced  down  into  XHv  pelvis,  is  squeezed  from 
ail  sides,  so  that  its  contents  are  expelled  "like  the  stone  from  a  cherry"  (Fig.  327). 


THE   THIRD   STAGE 


313 


Being  assured  that  the  bladder  is  empty  and  the  uterus  contracted,  the  fundus  is 
grasped  in  the  full  hand  with  the  thumb  in  front,  and,  while  the  fingers  are  pressed 
together,  the  uterus  is  firmly  but  gently  forced  down  in  the  line  of  the  axis  of  the 
pelvis.  One  ('rede  expression  properly  executed  will  almost  always  force  the  pla- 
centa into  the  vagina,  and  now  the  woman  expels  it  or  it  may  be  delivered  by  simph' 
expression.  The  further  treatment  of  such  a  pathologic  thirtl  stage  belongs  in  the 
chapter  on  Postpartum  Hemorrhage,  p.  770.

of  decidua,  and  even  of  pieces  of  placenta  are  more  common;  (c)  the  uterus  is  bruised;   painful 
after-pains  and  puerperal  infection  are  invited. 

Ahlfeld,  in  1S82,  proposed  a  purely  expectant  plan  of  treatment  of  the  tliird  stage.  The 
uterus  is  not  even  touchetl  after  delivery  unless  interference  is  necessary  because  of  very  profuse 
hemorrhage;  the  cord  is  drawn  over  tlie  tiiigh,  a  bed-pan  put  under  the  vulva,  or  the  patient 
is  put  over  a  hole  in  the  mattress,  the  escaping  blood  is  caught  in  a  funnel  leading  to  a  graduated 
vessel  under  the  be<l.  and  the  attendant  sits  at  the  bedside,  watcliing  her  face  and  counting 
her  pulse,- occasionally  taking  note  of  the  amount  of  blood  lost  externally.  If  the  placenta  is  not 
born  spontaneously  in  two  houi-s,  the  woman  is  asked  to  bear  down,  and  if  she  fails  to  expel  it, 
the  placenta  is  expressed  as  already  imlicateil.  .Vs  a  rule,  the  placenta  is  spontaneously  expelled 
in  three  or  four  hours,  but  without  aid  it  might  remain  until  putrefaction  sets  in.  Ahlfeld  claims 
for  his  method  that  tlie  loss  of  blood  is  less  than  with  Credes;  that  the  deciduae  are  usually  ex- 
pelletl  complete;  that  the  tearing  and  retention  of  the  membranes  and  placenta  are  less  frequent; 
that  the  puerperium  is  less  Ukely  to  be  morbid — with  all  of  which  the  author  cannot  agree.  In 
60  consecutive  cases  in  which  this  method  was  tried  the  author  fount!  the  hemorrhage  greater 
than  with  the  method  tirst  described  in  this  chapter,  and  there  was  no  difference  in  the  frequency' 
of  retention  of  pieces  of  membrane  or  ilecidua.  Other  investigators  have  confirmed  these  findings. 
Outsiile  of  the  greater  loss  of  blood,  wiiich  may  signify  much  to  a  small  or  anemic  woman,  the  con- 
stant anxiety  of  the  patient  throughout  the  long  hours  of  waiting,  the  prolongation  of  the  possi- 
bilities of  infection,  and  the  useless  expenditure  of  the  physician's  time,  contlemn  the  method. 
In  Dublin,  since  17S3,  and  in  England,  since  1775  (John  Har^•ie),  a  method  of  treatment  was 
practised  whose  essentials  were  the  guarding  of  the  uterus  with  the  hand  and  the  expression  of  the 
placenta  by  gentle  force  exerted  on  the  fundus  from  the  abdomen  fifteen  to  thirty  minutes  after 
the  child  was  delivered.     The  plan  recommended  by  the  author  is  based  on  the  DubUn  method. 

One  of  the  important  functions  of  the  obstetrician  is  to  save  the  T\-oman's 
blood.  Even  though  the  obstetric  patient  can  lose  enormous  quantities — as  much 
as  three  liters,  according  to  Ahlfeld — without  succumbing  to  hemorrhage,  these 
great  losses  leave  the  woman  debilitated,  anemic,  neurasthenic,  and.  if  not  these,  at 
least  protract  her  recovery  decidedly.  The  author  aims  to  conduct  all  labors  as 
nearly  bloodlessly  as  possible,  and  is  stronglj'  convinced  that  the  women  recuperate 
much  quicker,  suffer  less  infections,  nurse  their  babies  better,  and  altogether  are 
more  healthy  and  vigorous  than  those  who  have  suffered  the  losses  Avhich  are  given 
as  physiologic  in  most  text-books.  Excessive  hemorrhage  is  produced  by  improper 
conduct  of  the  third  stage.  The  accoucheur  should  hurrj-  the  process  of  separation 
of  the  placenta  only  in  the  presence  of  an  inchcation;  rough  massage  of  the  uterus  is 
to  be  avoided,  since  it  mashes  the  soft  placenta  to  a  pulp,  and  a  uterus  that  is  be- 
ha^^ng  well  should  not  be  excited  to  irregular  action.  All  these  conduce  to  re- 
tention of  pieces  of  placenta,  hemorrhage,  and  infection.  The  same  is  true  of  im- 
properly ]>erformed  and  frequent  Crede  expressions. 

Examination  of  the  Placenta. — This  is  a  part  of  a  physician's  work  which  may 
never  be  omitted,  hurried,  nor  delegated  to  another.  A  minute  and  systematic 
inspection  of  the  after-birth  is  made  as  soon  as  it  is  delivered,  while  the  hands  are 
still  sterile  and  the  patient  read}'  for  operation.  If  postponed  until  the  phj'sician 
is  about  to  leave  the  house  and  the  patient  alread}^  comfortably  settled  in  bed,  one  is 
loath  to  disturb  her  and  may  neglect  a  small  piece  of  placenta  which  may  be  found 
wanting,  and  trust  its  removal  to  nature,  when,  if  everything  were  aseptically  pre- 
pared, the  uterus  woukl  be  properly  emptied  of  its  contents,  and  late  hemorrhages, 
poh^pi,  subinvolution,  and  puerperal  infection  thus  avoided.  It  is  well  to  repeat  the 
inspection  of  the  placenta  before  it  is  destroyed.  Some  country  women  make  it  a 
practice  to  preserve  the  placenta  for  five  days,  in  order  that  the  physician  may 
inspect  it  if  fever  develops.  Under  a  good  light,  and  gently  rubbing  the  blood- 
clots  off  the  maternal  surface  with  a  piece  of  cotton  without  producing  new 
injuries,  the  accoucheur  goes  carefully  over  each  cotyledon  separately  and  success- 
ively. Beginning  at  one  point  in  the  periphery,  the  edge  is  followed  all  around  three 
times,  and  if  it  is  smooth  and  even,  in  all  likelihood  nothing  is  missing,  but  the 
center  of  the  placenta  must  also  be  examined  carefully.  A  gray,  smooth,  siiiny 
surface  (the  decidua  serotina)  is  a  positive  indication  that  that  portion  is  not  miss- 
ing, but  a  rough  place  requires  careful  attention.  If  the  torn  and  roughened  sur- 
faces fit  smoothly  without  forcing  the  cotyledons  together;  if  the  broken  and  jagged 
edges  of  the  thin  decidua  serotina  mortise  into  each  other  perfecth',  one  may  decide 


THE   THIRD    STAGE 


315 


that  nothing  is  missing  from  that  point.  Every  roughened  portion  of  the  placenta 
sliould  l)e  washed  with  water,  and  if  tlie  vilH  are  seen  free  and  floating,  one  may  i>e 
certain  that  a  hirger  or  smaller  portion  of  the  organ  lias  remained  attached  to  the 
uterus. 

Turning  the  organ  inside  out,  the  fetal  surface  is  .scrutinized,  the  presence  of 
cysts  noted,  but  especially  the  distribution  of  vessels.  If  the  ve.s.sel.s  all  disapj)ear 
l)efore  they  reach  the  edge,  one  may  ho  fairly  sure  that  a  placenta  succenturiata 
has  not  been  left  l)ehind  If  a  large  vessel  breaks  off  sharply  at  the  edge  of  the 
after-birth,  .search  .should  be  made  for  the  portion  it  supplicfl  (Fig.  320). 

The  membranes  also  mu.st  be  studied.  If  the  opening  through  which  the  infant 
came  is  round  and  complete,  usually  all  the  membranes  are  delivered.  The  empty 
ovum  sac  may  be  filled  with  water.  If  the  membranes  are  in  shreds,  the  parts  may 
be  fitted  togetiier  or  spread  on  a  sterile  towel.     If  torn  from  the  edge  of  the  phi-

Before  being  taken  from  the  bedside,  a  careful  scrutiny  of  the  placenta  is  made,  ail  blood-clots  being  wiped  away  with 
dry  gauze.     Note  posture  of  patient  and  the  fact  that  the  uterus  is  contracting. 


centa,  they  must  be  readju.sted  and  notice  taken  if  like  fits  like  structures.  The 
anmion  is  now  studied  separately  from  the  chorion.  Pieces  of  mi.ssing  chorion 
always  carry  decidua  with  them,  antl  are  especially  important  because  they  may 
also  c:irr>'  a  placenta  succeiit ui'iata  or  ])lacenta  spuria  with  them. 

Discovery  of  the  Absence  of  a  Placenta  Succenturiata. — The  pos.^ibility  of  the 
retention  of  an  extra  placenta  is  invariably  to  be  borne  in  mintl,  especially  since 
even  the  minutest  examination  of  the  delivered  portion  may  fail  to  give  ri.se  to 
suspicion  of  such  an  occurrence.  High  authorities  have  testifietl  to  this  point  in 
court.  Still,  an  investigation  with  this  particular  ol)ject  will  rarely  fail  to  discover 
the  true  conditions. 

If  the  membranes  are  torn  from  the  edge  of  the  placenta,  leaving  the  latter 
jagged,  thick,  and  rough:  if  a  blood-vessel  runs  to  the  edge  of  the  placenta  antl 
breaks  otY  sharply;  if,  with  velamentous  in-sertion  of  the  cord,  not  all  the  vessels 


316  THE    HYGIENE   AND    CONDUCT   OF    LABOR 

are  accounted  for;  if  there  is  an  extra  placenta  on  the  one  cleUvered;  if,  on  hokhng 
the  membranes  up  to  hght,  an  irreguhir  defect  in  the  chorion  is  found,  with  tliick- 
ened  and  vascular  margins:  if  the  phicenta  is  smaller  than  the  size  ot  the  child 
should  demand— one  mav  fe(>l  reasonably  sure  that  a  placenta  succentunata  is 
retained  in  the  uterus.  In  cases  of  real  doubt  the  uterine  cavity  is  to  be  explored. 
So  complete  an  examination  of  the  secundines  requires  all  of  ten  minutes,

during  which  time  the  nurse  guards  the  uterus,  stimulating  it  to  contraction  by

For  experimental  i)ur])os('s  milk  could  be  injected  into  the  placenta  through  the 
vein;  it  woukl  flow  in  a  large  stream  through  the  opening  left  by  the  missing  portion. 

When  to  Invade  the  Uterus. — Properly,  this  question  comes  up  in  the  patho- 
logic part,  but,  owing  to  its  importance,  it  will  bear  frequent  repetition.  The 
invasion  of  the  uterine  cavity  after  parturition  is  a  serious  procedure,  and,  done  as 
it  usually  is,  is  more  dangerous  tlian   most  laparotomies,  done  as  they   usually 


THE    THIRD    STAGE  317 

are.  Done  as  laparotomies  are  usually  done,  the  introduction  of  the  hand  is  not 
dangerous. 

In  his  recommendations  for  general  practice,  therefore,  a  teacher  is  bound  to 
consider  the  conditions  there  met,  and  the  qualifications  and  limitations  of  the 
attendant  physician. 

In  general  practice  it  is  safest  to  leave  the  membranes,  if  retained,  for  nature  to 
dispose  of,  which  she  usually  does — they  come  away  with  the  lochia,  in  pieces  or  as 
a  whole,  by  the  end  of  one  or  two  weeks.  Severe  after-pains,  fetid  lochia,  a  slight 
rise  of  temperature,  a  moderate  bleeding,  often  accompany  this  condition,  but  the 
puerpera  recovers,  though  a  chronic  endometritis  may  remain.  Even  if  all  the 
membranes  are  retained,  the  placenta  being  "decroAvned,"  most  authorities  recom- 
mend non-interference  in  the  absence  of  hemorrhage.  A  missing  piece  of  placenta, 
unless  it  is  larger  than  the  thumb-nail,  or  unless  it  causes  hemorrhage,  is  also  left 
to  the  natural  resources  of  the  woman.  The  hand  may  be  introduced  into  the 
uterus  only  under  the  strictest  indication,  vast  experience  having  shown  that,  under 
the  conditions  in  which  most  of  human  births  occur,  the  woman  is  safer  if  the  above 
rules  are  applied  and  much  trusted  to  nature. 

On  the  other  hand,  where  the  parturient  is  in  an  aseptic  maternity  hospital, 
and  where  the  accoucheur  has  at  his  service  ail  the  accoutrements  of  aseptic  opera- 
tion, he  may  make  the  attempt  to  spare  the  woman  the  ills  that  follow  the  retention 
in  the  uterus  of  membrane,  shreds  of  thick  decidua,  scraps  of  placental  tissue,  and 
iirm  blood-clots.  Persistent  oozing  of  blood,  which  sometimes  causes  decided  gen- 
eral anemia  before  it  ceases  spontaneously,  severe  after-pains,  fetid  lochia,  slight 
saprophytic  infections,  prolonged  lochial  discharge,  persistence  of  lochia  rubra, 
protracted  convalescence,  late  puerperal  hemorrhages,  subinvolution  of  the  uterus, 
which  may  result  in  chronic  metritis,  with  sterility  and  permanent  invalidism,  mild 
parametritis  with  later  shrinking  of  the  uterine  ligaments — all  these  may  be  avoided 
by  leaving  the  uterine  cavity  empty  and  the  walls  smooth  after  delivery.  It  must 
be  again  repeated,  however,  that  unless  the  conditions  for  aseptic  operation  are 
perfect,  the  primary  danger  of  infection  far  outweighs  the  advantages  to  be  gained. 

The  Asepsis  and  Antisepsis  of  the  Second  and  Third  Stages. — Antiseptic 
surgery  has  very  properly  given  way  to  aseptic  surgery.  The  principle  of  aseptic 
surgery  has  been  carried  over  to  obstetrics,  but  a  few  of  the  old  antiseptic  practices 
have  been  and  must  be  retained.  An  example  will  illustrate  this:  A  parturient  is 
ideally  prepared  for  delivery,  with  sterile  night-gown,  sterile  leggings,  sterile  sheets 
and  towels,  all  safely  (?)  pinned  together,  with  a  sterile  towel  under  the  buttocks, 
leaving  only  the  vulvar  orifice  exposed;  the  accoucheur  is  dressed  as  for  a  major 
laparotomy.  What  happens?  The  woman,  in  her  throes  of  pain,  tosses  about, 
disarranging  all  the  sterile  covers;  she  grasps  the  hand  of  the  attendant,  or  puts  her 
hand  over  the  sterile  towels  to  the  vulva;  with  the  pressing  efforts  feces  escape  from 
the  rectum,  and  soil  the  towel  under  her  or  the  towel  at  the  side  of  the  buttock,  and 
with  her  next  motion  these  are  spread  all  over  the  region  about  the  vulva;  the  sec- 
ond stage  drags  on,  one,  two,  or  three  hours,  dust  settles  on  the  extensive  area  of 
sheets,  leggings,  towels,  gloves,  gowns,  basins,  etc.,  which  are  supposed  to  be  sterile. 
How  many  of  these  things  are  really  sterile  when  the  actual  time  of  delivery  ar- 
rives and  may  safely  be  touched?  In  view  of  these  experiences,  and  because 
the  immense  majority  of  confinements  must  be  conducted  without  so  many  con- 
veniences, the  author  practises  and  teaches  a  very  simple  system  of  antisepsis. 
The  bed  is  dressed  with  sterile  sheets;  the  patient  is  in  a  sterile  night-gown;  sterile 
leggings  are  put  on;  a  sterile  towel  lies  under  the  buttocks;  another  covers  the 
belly,  but  nothing  is  draped  near  the  vulva,  and  the  only  towel  which  is  considered 
aseptic,  and  kept  so  by  frequent  changes,  is  the  one  on  the  bell}'.  If  it  is  impossible 
to  obtain  the  sterile  clothes,  clean  ones,  fresh  from  the  laundry,  are  as  good,  for 
they  are  not  touched  anyway  (Fig.  330).     The  accoucheur  must  put  on  a  sterilized

gOTVTi,  which  is  not  considered  sterile  after  it  is  on,  and  use  steriUzed  rubber  gloves, 
but  these  must  be  considered  sterile  and  must  be  kept  so  by  verj^  frequent  dipping 
in  actively  antiseptic  solutions. 

The  inside  of  basins  carrying  antiseptic  solutions,  the  hands  (gloved),  the 
region  innnediately  around  the  vulva,  and  the  towel  on  the  belly  are  the  only  ob- 
jects which  are  considered  sterile,  and  which  the  accoucheur  tries  to  keep  sterile. 
If  feces  issue  from  the  rectum,  thej^  are  caught  in  sponges  wrung  out  of  1 :  1500 
bichlorid,  and  the  region  of  the  anus  washed  with  the  same.     If  the  woman  touches

Only  the  area  of  skin  indicated    by  black  line  is  considered  aseptic.     The  towel  on  the  belly  (shown  folded  to

and  introitus  vaginae  are  frequently  sponged  with  1  per  cent,  lysol  and  1:1500 
bichlorid  solutions.  Since  the  child  is  delivered  "inter  feces  et  urinas,"  the  field 
can  never  be  considered  aseptic.  The  author  has  never  seen  ill  effects  from  the  liberal 
use  of  these  antiseptic  solutions  on  the  introitus  vulva  and  perineum,  and,  since 
investigations  have  proved  that  the  great(>st  danger  of  infection  arises  from  this 
region,  the  above  practice  is  justified.  Expedience  in  his  own  private  and  consulta-

pensary  has  also  convinced  him  that,  if  tiic  region  of  the  vulva  is  kept  aseptic  with 
antiseptic  solutions;  if  the  f^loves  are  kept  sterile  by  fre(|uent  innnersions  in  the 
ssLUUt,  and  if  the  few  objects  that  must  neeessaril^'  he  introduced  into  the  genitalia 
are  ahsolut(?ly  aseptic,  one  can  conduct  the  most  difficult  and  prolonged  obstetric 
manipulations  in  the  dirtiest  hovel  with  brilliant  results. 

Wherever  possible,  naturally  and  in  oi)stetric  operations,  the  precautions  and 
technic  of  the  laparotomy  are  practised. 

When  the  child  is  delivered,  the  hand  follows  the  uterus  thnjugh  the  sterile 
abdominal  towel.  After  the  cord  is  tied  the  accoucheur  rinses  his  gloves  very 
thoroughly  in  l>oth  solutions  (1  :  1500  bichlorid  and  1  per  cent,  lysol),  which  are 
then  made  up  fresh,  with  fresh  pledgets.  For  the  conduct  of  the  third  stage  he 
removes  the  gloves,  sterilizes  the  hands,  and  draws  on  fresh  sterile  gloves.  If 
there  is  no  time  for  this,  tin;  author  washes  his  gloves  with  pure  lysol.  New  gloves 
are  put  on  when  one  has  inadvertently  touched  some  unsterile  object  or  perforated 
the  first  pair.  After  the  ])lacenta  is  delivered  the  vulva  and  j)arts  about  it  are 
sponged  gently  with  1  :  1500  bichlorid,  taking  care  that  nothing  is  washed  into  the 
perineal  wound.  If  one  is  called  to  a  case  of  injury  to  the  perineum,  where  no  prep- 
aration of  the  patient  had  been  previously  made,  it  would  l)e  an  error  of  technic  to 
scrub  the  vulva  with  soap  and  water,  etc.,  and  thus  carry  infection  into  the  wound. 
One  should  treat  such  a  case  as  one  would  a  compound  fracture,  that  is,  clean  well 
around  the  edges,  guarding  carefully  against  carrying  anything  into  the  freshly 
opened  surfaces.  The  contiguous  skin  is  painted  with  tincture  of  iodin  by  some 
operators. 

Examination  of  the  Parts  for  Injuries. — Lacerations  of  the  outlet  may  be  ob- 
served during  tiie  delivery  of  the  child,  but  the  attendant  must  also  inspect  the 
parts  carefully  after  the  thirtl  stage.  Having  sponged  the  Ijlood  away,  the  fingers, 
holding  two  dry  pledgets,  gently,  under  good  light,  separate  the  labia  so  that  a 
perfect  view  of  the  vagina  and  perineum  is  obtained.  Thus  the  kind  and  extent 
of  the  birth  lacerations  are  discovered.  Unless  ther(>  is  hemorrhage,  the  author 
does  not  search  for  cervical  tears  after  spontaneous  deliveries.  In  all  breech,  in 
excessively  rapid,  and  in  all  operative  deliveries  the  author  insists  on  a  careful 
exploration  of  the  whole  parturient  canal,  followed  by  catheterization  and  rectal 
.examination,  to  determine  the  integrity  of  all  the  structures  involved  in  the  labor 
process. 

SUMMARY  OF  THE  CONDUCT  OF  THE  THREE  STAGES 

During  the  First  Stage. — (1)  Asepsis  and  antisepsis.  (2)  Diagnosis  of  the  case. 
(3)  The  prognosis  of  the  nieciianism  of  labor.  (4)  Watchful  (>xpectancv  and  recog- 
nition of  impending  danger  to  mother  and  babe.  (5)  Attention  to  bladder,  bowels, 
and  general  health  of  patient. 

During  the  Second  Stage. — (1)  Asepsis  and  antisepsis.  (2)  R(>lief  of  pain. 
(3)  Protection  of  life  of  infant  and  watching  for  comi)lications  which  threaten  the 
mother.     (4)  The  preservation  of  the  perineum. 

During  the  Third  Stage. — (1)  Prevention  of  postpartum  hemorrhage.  (2) 
Delivery  of  the  placenta.  (3)  Asepsis  and  antisepsis.  (4)  Tying  the  cord.  (5) 
Care  of  the  eyes.  (6)  Examination  of  the  placenta.  (7)  The  search  for  birth 
injuries. 

The  accoucheur  stays  in  the  house  at  least  one  hour  after  the  placenta  is  de- 
livered, time  which  may  be  profitably  employed  watching  the  mother  for  hemor- 
rhage, eclampsia,  etc.,  in  cleaning  instruments  and  packing  satchel  ready  for  the  next 
case,  the  filling  out  of  th<^  history  sheet  or  card  and  birth-certificate,  weighing  and 
measuring  tlu^  baby,  giving  instructions  as  to  after-care,  etc.  Before  leaving  the 
house  the  attendant  must  have  assured  him.self  on  these  seven  points:  (1)  That 
the  uterus  is  in  firm  tonus — that  is,  well  retracted  and  not  inverted;  (2)  that 


320  THE    HYGIENE   AND    CONDUCT   OF    LABOR 

there  is  no  hemorrhage  from  the  vulvar  orifice  and  no  internal  luMnorrhage;  (3) 
that  the  placenta  and  membranes  are  complete;  (4)  that  the  bladder  is  empty; 
(5)  that  all  perineal  tears  are  attended  to;  (())  that  the  child  is  in  good  condition — 
no  hemorrhage  from  the  cord,  and  that  it  breathes  freely;  (7)  that  the  mother  is 
in  good  condition,  with  good  pulse,  no  headache  (eclampsia),  no  vomiting. 

Let  us  pause  here  to  take  a  glance  back  at  the  treatment  of  labor  as  a  whole. 
It  should  be  regarded  as  a  surgical  operation:  it  really  is  such,  and  the  obstetrician 
is  really  a  surgeon.  He  considers  every  labor,  tiierefore,  first,  as  to  the  ability  of 
the  patient  to  stand  the  shock;  second,  he  provides  for  asepsis  and  antisepsis; 
thirtl,  he  carefully  watches  for  and  guards  against  comphcations. 

During  the  labor  the  accoucheur  observes  the  powers  and  estimates  the  resist- 
ances, judges  whether  the  powers  are  suflScient  to  overcome  the  latter;  he  watches 
the  mechanism  of  labor  as  its  various  phases  pass  under  the  eye  and  hand;  he  is 
always  alert  to  any  abnormality  in  the  mechanism,  and  keenly  alive  to  the  possi- 
bility of  some  outside  complication  occurring,  which  may  throw  either  or  both 
patients  into  acute  danger.  Through  all,  he  throws  around  both  patients  the  pro- 
tection from  infection  wliich,  of  recent  years,  has  become  almost  perfect. 

The  conduct  of  lal)or  is  not  a  simple  matter,  safely  intrusted  to  every  one. 
Let  the  people  know  that  having  a  child  is  an  important  affair,  deserving  of  the 
deepest  solicitation  on  the  part  of  the  friends,  needing  the  watchful  attention  of  a 
qualified  practitioner,  and  that  the  care  of  even  a  normal  confinement  is  worthy 
the  dignity  of  the  greatest  surgeon. 


PLACENTA    I'lCEMA  449 

seiitc'd.     i'erhups  tlu'  iiiaiintT  of  (Icvc'loiJincnt  of  the  placenta  pru'via  nuiy  oxjjlaiii 
these  variations  in  tiie  amount  of  heniorrlia}i;e. 

The  orit^in  of  the  hemorrhage  is  fourfold:  From  the  sinuses  of  the  i)laeentai 
site;  from  the  intervillous  spares  of  the  placenta;  from  the  circular  sinus  of  the 
placenta;  rarely,  and  then  only  as  the  result  of  interference,  from  the  villi — that  is, 
the  fetal  blood-vessels.  (Jwing  to  the  development  of  the  isthmus  uteri  and  the 
lower  uterine  sep^ment,  and  the  eonstant  upward  retraction  of  the  fillers  of  the  lower 
portion  of  the  uterus,  the  area  occupied  ]>y  the  jjlaceiita  is  enlarf^ed,  hut  the  pla- 
eental  growth  is  not  in  jjrojjortion.  Durinj^  the  painless  uterine  contractions  of 
pregnancy  the  lower  edge  of  the  placenta,  therefore,  is  likely  to  be  tlisunite<l  from 
the  wall  of  the  uterus,  opening  the  sinuses  and  allowing  maternal  bk)od  io  escape. 
It  is  easy  to  see  why  such  hemorrhage  is  called  unavoidable. 

Other  symptoms  of  ])lacenta  j)ra'via  are  both  inconstant  and  etiuivocal,  as 
pain,  pressure,  and  throbl)ing  in  the  lower  abdomen,  frequent  uriiKilioii,  leukor- 
rhea,  and  "earrjing  the  child  differently." 

Placenta  prsevia  affects  the  course  of  pregnancy,  labor,  and  the  i)uerperiuiM. 
Abortion  is  not  seldom  the  result  of  it,  though  Hofmeier,  in  sixteen  years'  exix-ri- 
ence,  could  not  find  one.  In  several  abortions  the  author  found  indubitable 
evidences  of  low  implantation  of  the  ovum.  Many  cases  of  i)lacenta  j^ra'via  give  a 
history  of  threatened  abortion  in  the  early  months.  Premature  rupture  of  the  bag 
of  waters  is  another  sign  of  low  insertion,  usually  the  marginal,  and  is  due  to  the 
adherence  of  the  membranes  arouiul  the  os,  from  catarrhal  endometritis  or  abnormal 
])lacentation.  Premature  labor  is,  therefore,  conunon.  Doranth  found  full-term 
labor  in  onl}'  32  per  cent.  Some  authors  mention  that  pregnancy  may  go  beyond 
term  in  placenta  praevia  centralis,  but  I  have  had  contrary  experience. 

During  labor  the  low  imj^lantation  of  the  l)ulky  jilacenta  causes  malpositions 
and  maljiresentations,  for  example,  i)reech  and  shoulder;  (lelaye<l  engagement  of 
the  head;  abnormalities  of  rotation;  prolajisus  funis;  weak  jiains — all  these  ])lus 
the  inevitable  hemorrhage  and  the  injuries  so  commonly  inflicted  by  operative  de- 
livery. Air-embolism  because  the  uterine  sinuses  are  so  near  the  external  air,  antl 
rupture  of  the  uterus,  because  the  musculature  is  weakened  by  the  ingrowth  of  the 
]ila('enta,  are  commoner  than  usual. 

Postpartum  hemorrhage  is  very  frequent,  because  the  uterine  wall  is  thin  and 
weak  in  muscle,  which  contracts  tardily,  and  closes  imperfectly  the  large  venous 
sinuses,  also  often  being  unable  to  separate  the  placenta.  Further,  the  j^lacenta  is 
likely  to  be  adherent  because  of  endomc^tritis,  infarction,  ingrowth  of  villi  (jilacenta 
accreta.  Fig.  704),  or  from  infection  during  pregnancy,  the  placenta  being  so  near 
the  septic  vagina.  Did  not  the  uterine  arteries  enter  the  uterus  higher  up  and, 
therefore,  in  the  zone  of  contraction,  many  women  would  bleed  to  death,  because 
the  clotting  in  the  vessels  is  not  sufficient  to  procure  hemostasis.  No  doubt  many 
cases  of  ])()st]^artum  hemorrhage  are  due  to  low  implantation. 

In  the  pucrperium  placenta  prievia  also  makes  trouble:  ((/)  Bits  of  placenta 
may  remain  adherent  and  become  infected;  (b)  from  the  close  proximity  of  the 
placental  site  to  the  septic  vagina,  infection — and  that  of  the  most  dangerous  kind, 
metr()))hlebitis — is  invit(>d;  (r)  subinvolution,  and  (»/)  finally  tln'  woman  has  the 
profound  anemia  to  contend  with. 

These  dangers  beset  the  child:  j)rematurity  and  atelectasis  puhnonum;  a 
much  infarcted  or  ill-tleveloped  jilacenta  causes  the  infant  to  be  puny;  prolapse  of  the 
cord;  comjiression  of  the  insertion  of  same,  and  dislocation  of  the  i)lacenta  during 
delivery,  may  cause  asphyxia;  injury  of  the  placenta  causes  fetal  hem(»rrhage;  an<l 
the  infant  may  suffer  from  the  forceps  or  version,  but  especially  from  the  use  of  its 
boily  as  a  tampon  to  stop  hemorrhagi'^ — the  Braxton-Hicks  method. 

Diagnosis. — A  painless,  causeless,  uterine  hemorrhage    n  the  last  three  months 
of  pregnancy  usually  enables  a  direct  diagnosis  of  placenta  prievia  to  be  made,  but 
29 


450      THE  PATHOLOGY  OF  PREGNANCY,  LABOR,  AND  THE  PUERPERIUM 

the  t'oiiclusion  must  l^e  certified  by  vasinal  examination  and  tlu^  finding  of  placental 
tissue  over  the  internal  os. 

Before  making  the  internal  examination  everything  must  l)e  pre])ared  as  for 
operation,  and  great  gentleness  is  to  be  practised  to  avoid  se])arating  and  tearing 
the  placenta,  the  dangers  being  maternal  and  fetal  bleeding.  It  has  happened  that 
the  mere  insertion  of  the  finger  into  the  cervix  has  provoked  such  alarming  hemor- 
rhage that  treatment  had  to  be  instituted  there  and  then. 

The  peculiar  spongy,  fibrous  feel  of  the  placental  tissue  may  l)e  simulated  by  a 
firm  coagulum,  by  thick  vernix  caseosa  in  matted  hair,  by  a  monstrosity  with  ex- 
posed ^•iscera, — for  example,  anenccphalus, — by  hemorrhage  into  the  fetal  mem- 
branes (which  may  indicate  a  placenta  located  near  by),  and  by  thickened  mem- 
branes. Bogginess  in  the  fornici^s,  the  sensation  of  a  flat  sponge  between  the  head 
and  the  fingers,  pulsating  arteries,  excessive  vascularity,  and  a  low  and  pronounced 
uterine  souffle  are  all  equivocal  signs  of  placenta  prsevia. 

In  the  differential  diagnosis  bleeding  from  varicose  veins,  hemorrhoids,  etc., 
are  easily  excluded,  but  ruptura  uteri,  ectopic  gestation,  and  al)ruptio  placentae 
need  more  care.  (See  p.  441  for  a  table  which  gives  the  differential  points  con- 
cerning the  last  mentioned.)  It  must  be  remembered  that  a  placenta  situated  low 
in  the  uterus  without  being  actually  a  prsevia  may  become  partly  detached  at  its 
lower  pole,  and  the  point  of  bleeding  being  near  the  os,  the  blood  escapes  readilj^, 
not  increasing  intra-uterine  tension  and  not  separating  the  placenta  entirely.  In 
such  instances  the  signs  of  abruptio  may  be  wanting.  Then,  too,  in  the  severest 
cases  of  abruptio  placentie  the  organ  may  prolapse  and  come  to  lie  over  the  os. 

Rupture  of  the  uterus  is  easily  shut  out,  but  one  must  remember  the  tendency 
of  the  uterus  to  rupture  when  the  placenta  is  low. 

Bleeding  from  a  vessel  passing  over  the  os  from  a  velamentous  insertion  of  the 
cord  must  also  i)e  thought  of,  and  also  laceration  of  the  circular  sinus. 

Another  point  to  be  determined  by  the  internal  examination  is  whether  the' 
previal  portion  of  the  placenta  is  central,  lateral,  or  only  marginal — which  is  not 
always  easy.  Sweeping  the  finger  delicately  around  the  internal  os,  the  accoucheur 
notes  where  the  thin  membranes  become  thicker,  then  passing  into  the  thick  pla- 
cental margin.  If  the  student  will  lay  a  placenta  over  a  ring  made  by  his  fingers, 
he  can  practise  the  diagnosis  of  placenta  prsevia  as  on  the  living. 

Prognosis. — Placenta  prsevia  is  a  formidable  complication,  and  annually  sacri- 
fices more  mothers  and  children  than  appear  in  statistics.  These  figures,  collected 
from  many  sources,  will  give  an  idea  of  the  mortality  of  mothers  and  children.

This  ta})le  shows  that,  of  2153  women  with  placenta  pra^via,  16G  died,  a  per- 
centage of  7.7,  which  is  very  much  better  than  fifty  years  ago,  by  grace  of  asepsis 
and  better  obstetric  practice.  The  Berlin  Frauenklinik  showed  3.8  per  cent,  of 
deaths  in  467  cases,  and  Schauta's  Vienna  cHnic,  5.85  per  cent,  in  342  cases.  Kronig 
collected  6569  cases  which  showed  mortalities  of  9.3  per  cent,  and  58.7  per  cent, 
respectively  for  mothers  and  children.  Fiith  collected  72()  cases  from  private 
practice  near  Koblenz,  and  found  hVA  deaths,  19.7  per  cent.,  with  an  infant  mor-

tality  of  48  per  cent.  McPhcrson,  in  2n{)  cases  in  the  New  York  Lyinfi-in  Hosj)ital, 
found  IS  per  cent,  and  57  per  cent.,  hut  in  this  are  included  tlie  nioriWund  ca.ses. 
McDonald  collected  reports  of  8025  cases,  and  found  7.22  per  cent,  and  55.5  per 
cent,  mortalities  for  mothers  and  children  respectively. 

All  the.se  figures  recjuire  careful  .study  before  being  applied  to  an>-  purpcse, 
especially  f(jr  deciding  on  methods  of  treatment,  Ix'cau.se  the  condition  of  the  pa- 
tient, whether  she  was  infected  before  admission  to  treatment,  the  degree  of  the 
prievia,  total  or  partial,  the  jxTiod  of  gestation,  the  amount  of  blood  lost  previously, 
the  manner  of  treatment,  etc.,  nmst  all  be  properly  evaluated — which  is  impcssible. 
One  man's  opinion,  if  he  is  (jualified  by  general  mental  ability  and  clinical  exj)erience 
to  render  an  opinion,  is,  theref(jre,  usually  more  useful  in  dei-iding  on  lines  of  treat- 
ment than  the  largest  statistics.  The  highest  mortality  occurs  in  central  jjlacenta 
prievia;  the  lowest  in  the  marginal  variety,  which  is  true  for  both  mother  and  infant. 

Most  of  the  deaths  in  placenta  pnevia  come  from  hemorrhage,  sepsis,  rupture 
of  the  uterus,  and  air  embolism,  named  in  the  <jr<ler  of  frecjuency.  The  woman 
l)lee(ls  to  death  in  labor  usually  becau.se  her  store  of  blood  has  been  wasted  during 
pregnancy,  or  from  an  injury  inflicted  by  delivery.  Sepsis  is  invited  by  the  proxim- 
ity of  the  suscejitibic  i)lacental  site  to  the  field  of  operation,  and  the  fact  that  ha.sty 
and  many  manipulations  are  necessary  in  the  treatment.  Rupture  of  the  uterus 
is  usually  the  result  of  violence  exerted  by  the  accouclieur,  but  may  occur  from 
tumultuous  uterine  action.  Air-embolism  is  rare,  but  does  occur,  exjieriments  on 
animals  to  the  contrary  notwith-standing.  The  children  die  from  a.sphyxia  through 
dislocation  or  compression  of  the  placenta,  tearing  of  the  placenta  and  fetal  hemor- 
rhage', from  being  used  as  a  ])lug  in  the  Braxton-Hicks  treatment,  further,  from 
prematurity.     Later  methods  of  treatment  have  improved  the  child's  chances. 

The  prognosis  as  to  health  is  also  bad.  Puerperal  infection  is  of  very  fretjuent 
occurrence,  resulting  in  life-long  invalidism;  the  anemia  may  cause  permanent 
changes  in  the  blood-forming  organs  and  in  the  nervous  system,  and  the  woman 
may  be  lianiagecl  In'  the  operations  i>erformed  for  delivery. 

Treatment. — FortunateU',  we  possess  rational  anil  certain  methods  of  treat- 
ment for  this  formidable  accident,  w'hich  cannot  be  said  of  most  other  obstetric 
complications.  In  deciding  on  tiie  course  of  procedure  in  the  individual  ease  many 
factors  must  l)e  considered:  the  surroundings  of  the  ])atient;  the  condition  of  the 
mother  and  that  of  the  child;  the  necessity  for  preserving  it  (Catholic  family);  the 
skill  of  the  accoucheur;  the  degree  of  the  pnevia — whether  j)artial  or  total;  whether 
the  patient  is  in  labor  or  not;  and  the  amount  of  dilatation  of  the  cervix.  From 
his  own  experience,  and  from  thoughtful  consideration  of  the  ]nil>lished  exT^erience 
of  others,  the  author  would  lay  down  these  axioms: 

1.  A  woman  with  i)lacenta  pru'via  should  not  die,  excejit  in  the  very  ran^  in- 
stances of  air-embolism,  hemorrhagic  diathesis,  or  s])ontaneous  rui)ture  of  the  uterus. 

2.  Every  woman  with  placenta  pra^via  should  be  sent  to  a  well-equipped  ma- 
ternity hospital  unless  she  is  able  and  willing  to  ])rovide  the  several  i)hysicians  and 
nurses  necessary  in  her  own  home.  It  is  otherwise  impossible  to  give  th<'  patient 
all  the  benefits  of  our  art. 

3.  With  two  exceptions  every  pregnancy  complicated  with  ])lac<>nta  iirrrvia 
should  be  terminated  as  soon  as  the  diagnosis  is  made.  When  the  bleeding  is  in- 
deed slight,  and  when  the  child  is  very  near  the  border  of  viability,  one  may  tem- 
porize a  few  weeks,  proriding  the  patient  will  reinain  ifi  bed  in  a  gaod  muter nitij  hos- 
pital. Should  the  woman  refuse  to  go  to  the  hospital,  and  al.so  to  allow  the  ac- 
coucheur to  induce  labor  at  her  home,  the  attendant  had  better  droj)  the  case  and 
let  the  jiatient  employ  a  physician  in  whom  the  gambling  instinct  is  better  develo]K'<l. 
A  "fiooding"  may  occur  during  the  night,  and  the  woman  lose  a  fatal  amount  of 
blood  before  aid  can  reach  her.  Dr.  W.  W.  Jaggard  said,  "there  is  no  exi)eciant 
plan  of  treatment  for  ])lacenta  pra'via." 


452      THE  PATHOLOGY  OF  PREGNANCY,  LABOR,  AND  THE  PUERPERIUM 

4.  One  must  distinguish  sharply  between  maternity  and  private  practice, 
measures  which  are  safe  in  the  former  being  im]wssible  in  the  latter.  In  the  ma- 
ternity hospital  one  may  make  a  consistent  effort  to  save  the  life  of  the  child,  but 
at  the  home  one  must  use  that  method  which  will  put  an  immediate  stop  to  the 
hemorrhage,  with,  if  necessary,  less  regard  to  the  child.  Also  the  accoucheur  will 
select  the  procedure  which  he  is  best  able  to  carry  out,  and  nmst  know  all  methods 
of  delivery,  as  well  as  be  able  to  suture  the  cervix  and  perform  vaginal  and  abdom- 
inal hysterectomy,  etc, 

5.  When  labor  has  begun  in  a  case  of  placenta  prsevia,  the  accoucheur  must 
remain  by  the  patient  until  she  is  delivered  and  out  of  danger. 

6.  At  all  times  in  the  treatment  of  these  cases  the  accoucheur  should  heed  this 
warning,  save  blood!  One  can  never  foretell  how  much  of  the  vital  fluid  the  woman 
will  lose  in  the  successive  stages  of  treatment,  nor  does  one  know  what  is  the  par- 
ticular woman's  ability  to  withstand  bleeding.  A  loss  of  a  pint  will  kill  one  woman, 
while  another  will  recover  from  the  loss  of  three  quarts.  Be  not  extravagant  \yith 
her  supply  during  the  first  and  second  stages  of  labor,  because  the  normal  flow  in 
the  third  stage  may  be  a  fatal  drain.  Therefore  if,  on  arrival  at  the  bedside,  the 
accoucheur  finds  the  woman  already  anemic,  it  is  unwise  to  use  uncertain  methods, 
but,  regardless  of  all  else,  the  hemorrhage  must  be  arrested  at  once  and  every 
possible  drop  of  blood  spared. 

During  pregnancy,  before  labor-pains  have  begun,  if  one  has  decided  to  assume 
the  risk  and  to  temporize,  the  woman  should  be  put  to  bed  at  the  first  indication 
of  hemorrhage,  and  she  should  be  in  a  perfectly  appointed  maternity  hospital.  If 
the  hemorrhage  is  free,  a  firm  vaginal  tampon  is  to  be  applied.  In  all  cases  of 
hemorrhage  during  pregnane}'  a  firm  tampon  is  indicated,  in  order  to  limit  the'  loss 
of  blood  to  a  minimum.  If  the  woman  is  to  be  transported  to  a  hospital,  a  provi- 
sional tampon  is  to  be  applied,  as  the  unavoidable  jolting  on  the  way  will  increase 
or  incite  the  bleeding.  The  application  of  a  tampon  to  control  hemorrhage  is  by 
no  means  a  simple  matter.  Unless  the  head  is  engaged  in  the  pelvis,  it  is  impossible 
to  apply  the  tampon  so  firmlj-  that  all  bleeding  will  be  stopped,  and  since  the  head 
rarely  has  sunk  so  low,  one  must  be  content  with  checking  the  fiow\  Dry  sterile 
cotton  is  best  for  the  purpose,  and  the  rules  of  asepsis  must  be  especially  strict. 
Counterpressure  is  to  be  applied  with  a  firm  abdominal  binder,  as  in  Fig.  403. 
Even  an  aseptic  tampon  aseptically  applied  becomes  a  source  of  danger  very  soon, 
and  for  this  reason  it  should  be  removed  in  twelve  hours  and  not  renewed  unless 
absolutely  necessary.  On  the  appearance  of  another  hemorrhage  action  is  de- 
manded— there  is  no  A\'isdom  in  waiting  longer.  It  is  a  wanton  exposure  of  the 
mother  to  innnediate  and  future  danger  for  the  sake  of  an  infant  which  Avill  prob- 
ably succumb  during  delivery  or  shortly  after. 

If  the  patient  is  near  the  ninth  month,  the  child  is  viable  and  well  developed, 
and  on  its  account  there  is  no  reason  for  waiting. 

During  labor  we  have  four  objects  to  accomplish:  First  and  most  urgent,  to 
stop  the  hemorrhage;  second,  to  empty  the  uterus;  third,  to  insure  hemostasis; 
fourth,  to  combat  the  anemia. 

We  must  stop  the  hemorrhage,  then,  first  of  all,  and  it  matters  a  great  deal 
whether  the  patient  has  already  lost  much  or  little  ])lood  when  it  comes  to  the  selec- 
tion of  the  method  of  stanching  the  flow. 

In  cases  of  marginal  placenta  pra^via  the  hemorrhage  usually  begins  toward  the 
end  of  the  second  stage  of  labor  and  is  very  slight.  The  proper  treatment  is  to 
puncture  the  bag  of  waters.  This  method  is  named  after  Puzos,  who  mentioned  it 
(1759),  but  Puzos  knew  nothing  of  the  nature  of  placenta  praevia,  and,  further, 
Mauriccau  ruptured  the  membranes  to  stop  hemorrhage  in  1688.  Both  considered 
detachment  of  the  placenta  the  cause  of  all  the  hemorrhages  during  pregnancy. 

The  puncture  of  the  membranes  allows  the  placenta  to  retract  with  the  receding

of  waters  will  fail  to  arrest  \hv  i\ow.  Such  cases  are  treated  like  central  and  lateral 
implantation. 

The  usual  condition  met  is  a  more  or  less  severe  hemorrluige,  with  the  os  ad- 
mitting two  or  more  fingers.  Pains  may  or  may  not  ])e  present,  ])ut  some  uterine 
action  nmst  have  taken  place  or  the  hemorrhage  and  dilatation  could  not  have 
oecmTed. 

There  are  now  two  methods  of  treatment— Braxton-Hicks'  version  and  met- 
reurysis. Which  one  should  beselected  dependson  several  conditions.  If  the  woman 
hai^  lost  much  blood;  if  the  babe  is  dead  or  dying,  or  if  it  is  very  jiremature,  so 
that  its  chances  are  very  slim;  if  one  has  had  little  experience  with  placenta  pra^via — 
Braxton-Hicks'  version  is  preferable.     Bring  down  one  foot,  make  slight  traction  on 


Fig.  414. — Br.^xton  Hicks'   Version  Completed. 

Breech  acts  as  tampon  and  squeezes  placenta  against  bleeding  vessels.     It  is  essential  for  success  to  be  certain  that

it,  so  that  the  infant's  thigh  compres.ses  the  placenta  against  the  cervix,  thus  sto]> 
ping  the  hemorrhage.  Then  leave  the  case  to  nature.  Do  not  extract  the  child;  do 
not  put  traction  on  the  leg  unless  bleeding  recurs.  If  oozing  commences,  pull 
lightly  on  the  leg.  The  object  of  this  method  is  to  use  the  child's  body  as  a  cer- 
vical tampon  to  .stop  hemorrhage,  and  to  stimulate  pains  until  the  cervix  is  ready 
for  safe  delivery.  Neglect  of  the  above  advice  and  rapid  extraction  have  cost  many 
mothers  their  lives,  and  the  object  sought,  the  saving  of  the  child,  has  usually  been 
frustrated  by  the  attempt  itself. 

In  performing  Braxton-Hicks'  version  these  points  are  to  be  noted.  Puncture  tlie  mem- 
branes at  the  side  of  the  cervix  as  far  from  the  edge  of  tlie  placenta  as  possible  (Fig.  412).  Then, 
di.sregur(ling  the  bleeding,  which  now  conmicnees  and  is  .sometimes  furious,  pass  the  hand  into  the 
vagina, the  two  fingers  through  the  rent  in  the  membranes  alongside  the  head.  The  head  is  gently 
pushed  to  one  .side,  while  the  outside  luuid  pre.s.ses  finst  the  breech,  then  the  foot,  down  in  the  direc- 
tion of  the  inside  fingers.  The  fingers  .seek  the  foot,  and  as  soon  as  this  is  grasped,  it  is  led  down 
into  the  vagina.  It  is  then  very  gently  drawn  out,  the  other  hand  outside  pressing  the  head  up- 
ward toward  the  fundus.     The  secret  in  the  performance  of  Braxton  Hicks'  version  is  complete

anesthetic  may  bo  necessary  for  a  few  moments,  but  :i.s  myim  as  the  fo(jt  is  secured  the  mask  should 
be  removed,  because  anemic  jjatients  do  not  do  well  with  anesthetics. 

If  the  pla(;enta  covers  the  entire  os,  it  is  not  advisable  to  waste  valuable  8econ<ls  in  seeking 
its  edge.     It  is  better  to  bore  through  the  mo.st  accessible  pfjrtion. 

It  happens  occasionally  that  delay  is  cau.sed  in  perf(jrming  the  version  after  the  membranes 
have  been  punctured.  I*erha|)s  (lie  patient  is  imruly  or  rigid,  or  the  bleinling  may  become  so 
great  that  one  fears  for  the  mother's  life.  In  such  ca.ses  the  bleeding  may  b<"  tempfirarily  cliecke<l 
by  grasi)iiig  the  placenta  ami  uterine  wall,  as  in  I'ig.  4l'A.  This  will  give  the  oj)erator  time  to 
collect  himself.  Allot  her  way  is  to  gras|)  the  whole  cervix  with  the  inside  hand,  pn-ss  it  against 
the  head,  while  the  outside  hand  f(»rces  the  whole  uterus  down  into  the  pc-lvis.  We  must  strive  to 
save  blood  every  inch  of  the  way.

After  tlio  version  the  ca.-^e  is  al)solutely  under  eontrol  (Fiji.  111).  If  the  phi- 
centa  is  pressed  flat  against  the  uterine  wall,  the  woman  ean  bleed  no  more,  and 
meastires  may  be  instituted  to  replaee  the  blood  she  luus  lost.  Salt  solution  is

It  is  applical^le  at  all  stages  of  cervic-al  dilatation,  before  the  os  is  sufficiently  open 
to  permit  tlelivery.  It  may  be  used  to  induce  labor,  or  it  may  be  used  when  version 
has  been  tried  and  has  failed.  One  may  dilate  the  cervix  sufficiently  to  proceed 
-svith  inmiediate  delivery,  or  one  may  dilate  sufficiently  for  the  performance  of 
version,  after  which  the  case  may  be  treated  according  to  conditions  as  they 
arise.  The  colpeurynter  (or  metreurynter)  marks  nearly  as  great  an  advance 
in  the  treatment  of  placenta  prsevia  as  did  the  introduction  of  Braxton-Hicks' 
version.  ^Metreurysis  is  used  in  cases  where  the  condition  of  the  mother  and  child 
is  good.  When  the  mother  has  lost  little  blood  and  the  child  is  viable,  we  may 
take  a  reasonable  chance  on  a  little  greater  hemorrhage  for  the  sake  of  the  infant. 


Fig.  41(j. — Filling  Colpeurynter.     (Some  operators  prefer  a  piston  syringe.) 


Several  bags  are  on  the  market.  The  original,  Carl  Braun  colpeurynter,  is  as  good  as  any 
of  the  later  modifications,  and  I  use  it  considerably  (Fig.  795,  p.  911).  Voorhees,  of  New  York, 
made  a  modification  of  the  Champetier  de  Ribes'  inelastic  conic  balloon,  which  is  very  service- 
able, and  sizes  may  be  gotten  large  enough  to  secure  complete  dilatation.  I  use  it  in  cases  in  which 
the  head  is  low  in  the  pehns,  as  its  flat  top  does  not  displace  the  head  much. 

All  preparations  are  made  beforehand.  The  bag  and  the  bulb  syringe  for  filling  arc  steriHzed 
by  boiling  twenty  minutes  in  plain  water.  The  colpeurynter  is  einptied  of  air  first.  This  is 
accomijlished  by  filling  it  with  0.5  per  cent,  lysol  solution,  then  inverting  it  so  that  all  this  tiuid 
runs  out.  A  clamp  is  now  affixed  four  inches  from  tlie  end  of  the  tube.  The  air  is  all  pumped 
out  of  the  bulb  syringe  and  the  nozle  fitted  into  the  end  of  the  tube  of  the  colpeurynter.  For 
greater  security  this  tube  may  be  tied  on  with  tape.  The  bag  is  now  fold(>(l  lengthwise  into  as 
narrow  a  compa.ss  as  possible,  and  then  grasped  by  the  long  uterine  packing  forceps.  The 
whole  apparatus  lies  in  a  basin  of  0.5  per  cent.  Ij'sol  solution,  from  which  it  is  to  be  filled. 

The  membranes  are  now  punctured  as  for  the  performance  of  version,  and,  operating  quickly, 
guided  by  the  two  fingers  in  the  cer\'ix,  the  bag  (Fig.  415)  is  placed  inside  the  uterus  on  top  of  tfie

tube,  and  steadyiiiji  the  eolpeurynter  <jn  the  plarenta,  the  otlx-r  han<l,  by  slow  pressures  on  the  bulb 
of  the  syringe,  inji-cts  the  recjuired  amount  of  lysol  solution  (Kin.  41()).  Fourteen  to  20  ounces  are 
required,  varying  in  individual  cases.  Each  full  compression  of  the  bulb  of  the  .'^yringe  is  ab<iUt 
one  ounce,  and  in  this  way  the  amoimt  may  be  <'stimated.  If  the  child  is  small,  tlie  bail  n«'«Hl  not 
be  fully  distended;  if  the  i)atient  is  at  term,  IS  to  "JO  ounces  are  neede«l.  If  t<K>  much  .S4jluti(jn  is 
injected,  tiie  l)an  will  not  apply  it.self  to  the  placenta,  and  hemorrlunic  will  continue,  utxtn  xn-ing 
which  one  will  allow  a  few  ounces  to  escape  Ihrou^^h  the  tube.  If  t(j(j  lit  tie  is  injected,  thee<j||M'urynter 
will  fall  out  before  the  osissufHciently  (lilated.  One  must  inject  slowly  in  order  not  to  overdistend, 
and  too  rapidly  stretch,  the  lower  uterine  segment.  The  head,  <jf  course,  is  di.splac*"*!  by  the  c-ol- 
peurynter,  but  this  cannot  be  avoided.  Since,  when  the  bap;  is  e.xpelled,  delivery  is  consummate*!, 
little  harm  results  from  displacing  the  head.  After  the  ban  i-s  in  positi<»n  one  reassun'S  him.self  that 
the  placenta  is  underneath  it,  and  not  doubled  up(m  itself,  an<l  withdraws  the  hand  from  the  vajtina. 
Now  the  tube  is  clamped  with  :in  artery  force|)s  an<l  slight  traction  exerted  on  it  (Kijf.  417j.  Only 
sufficient  pressure  is  brought  to  bear  on  the  |)lacenta  and  cervix  as  will  stop  tin-  lu-morrhage.

one  may  insert  a  scale  in  the  lin(>  of  traction,  or  fasten,  by  means  of  a  tape,  a  bottle  containinp 
the  proper  amount  of  water,  and  hanp  it  over  the  foot -board  of  the  be<l. 

I  prefer  to  hook  the  ordinary  baby  scale  into  the  artery  forceps,  or  pull  on  it  myself,  and  thus 

Eersonally  watch  the  traction.  Every  three  or  four  minutes  one  should  relax  the  pull  to  allow 
lood  to  jjet  into  the  cervix.  An  anemic  cervix  will  tear  more  readily  than  one  properly  nourished. 
Pains  usually  come  on  within  an  hour,  and.  while  they  are  irrejrular,  tiny  accomi)Iish  the 
effacement  and  dilatation  of  the  cervix.  After  an  hour  or  .so  the  jiains  become  mon'  regular. 
One  relaxes  the  pull  on  the  baR  durinp  the  pain,  resuming  it  when  the  contraction  is  over.  Atoi(l 
too  jwurrfiil  traction  on  the  hag.  This  may  rupture  the  cervix  and  lower  uterine  .>j<«pment  directly, 
or  it  may  excite  such  powerful  uterine  action  that  this  niptures  the  uterus.  I  have  had  one  .such 
accident.  Indee<l,  the  pains  must  not  be  allowed  to  become  too  strong  in  placenta  previa.  If 
such  a  tlanger  threatens,  stop  jjulling  on  the  bag,  and  if  this  doi-s  not  protluce  the  desired  effert, 
allow  several  ounces  of  fluid  to  escape  from  the  bag. 

The  obstetrician  must  po.s.sc.ss  a  large  fimd  of  patience,  as  he  may  be  required  to  hold  onto 
the  eolpeurynter  for  from  three  to  twelve  hours. 

The  next  jmint  of  importance  in  the  treatment  is  to  determine  the  exact  moment  when  the 
eolpeurynter  pas.ses  through  tlie  cervix.  If  one  neglects  to  note  this,  pidling  on  the  tube  brings 
the  bag  down  onto  the  perineum  and  a  large  quantity  of  blood  accunmlatea  between  it  and  the 


458  THE    PATHOLOGY   OF    PREGNANCY,    LABOR,    AND    THE    PUERPEWUM 

chiKl  (Fig.  41S).  It  is  a  very  serious  loss,  because  one  cannot  control  the  hcniorrha.se  so  well 
after  dilatation  of  the  cervix  as  before,  unless  it  is  possible  to  deliver  at  once.  Sometimes  the  head 
follows  down  and  takes  the  place  of  the  colpeurynter,  tamjioning  the  cervix  securely.  These  are 
fortiuiate  cases,  and  one  has  notliing  to  do  Imt  watch  and  let  nature  take  the  lead.  It  is  advisable, 
as  soon  as  the  head  has  passed  the  c{>rvix,  to  deliver,  because  the  child's  life  is  in  a  rather  ])recarious 
position,  and,  second,  the  placenta  may  s(^parate  and  blood  may  accumulate  in  the  uterine  cavity. 

The  accoucheur  determines  that  the  colpeurynter  is  passing  the  cervix,  first,  by  noting  the 
steady  advancement  of  the  tube;  by  occasional  direct  internal  examination  one  feels  the  cervix 
slipping  over  the  greatest  circumference  of  the  bag;  third,  the  j)atien(  begins  to  bear  down,  and 
the  pain  has  a  sharp,  cutting  character;  fourth,  after  th(>  bag  has  passed  through,  the  pains  cease 
or  are  milder;  fifth,  the  bag  is  expelled — but  the  two  latter  signs  show  delinc]uency  on  the  part  of 
the  accoucheur.  By  the  time  the  bag  comes  to  pass  through  the  cervix,  the  attendant  must  be 
ready  to  deliver  or  to  do  a  version,  as  indicated.  The  time  consumed  in  getting  ready,  after  the 
bag  has  slipped  through  the  os,  may  mean  a  fatal  loss  of  blood. 

If  the  head  does  not  follow  the  metreurynter  into  th(>  i)elvis,  the  operator  withdraws  the  bag 
quickly  from  the  vagina,  emptying  it,  if  necessary,  as  quickly  inserts  his  whole  hand,  and  grasps 
the  cervix  and  placenta  until  he  can  determine  on  the  course  of  procedure.     If  the  head  is  still 


Fig.  4 is. — Bag  has  Passed  the  Cekvix  and  Blood  has  Accumulated  Behixd  It. 

high,  he  tries  to  force  it  down  into  the  pelvis.  This  will  stop  the  hemorrhage  and  allow  the  forceps 
to  be  applied.  If  the  head  does  not  go  into  the  pelvis,  podalic  version  is  to  be  performed.  If 
the  cervix  is  not  sufficiently  dilated  by  the  first  attempt  with  the  colpeurynter,  one  may  reinsert 
it  and  fill  it  with  a  still  larger  amount  of  water, — 20  to  24  ounces, — which  will  dilate  the  os  to  the 
size  of  the  fetal  head. 

The  heart-tones  of  the  child  iiuist  bo  carefully  noted  after  the  vension  is  done 
and  (hiring  the  time  th(^  colpeurynter  is  in  place.  If  the  cord  is  in  the  area  of  the 
placenta  compressed  by  the  breech  or  colpeurynter,  some  asphyxia  of  the  infant  is 
unavoidal)le.  This  may  not  be  fatal,  but  is  very  unwelcome,  the  more  so  because 
we  are  practically  powerless  to  extract  the  child  until  the  cervix  is  dilated.  The 
most  we  can  do  is  to  try,  if  safe,  to  hasten  the  dilatation  of  the  cervix  somewhat. 
This  is  done  by  exertin"-  a  little  more  traction  on  the  breech  or  bag,  say  23/9  ])ounds — 
with,  of  course,  the  precautions  already  emphasized.  If  an  urgent  indication  on 
the  part  of  the  child  for  delivery  should  arise  before  the  cervix  is  sufficiently  dilated, 
it  will  have  to  })e  disregarded.  The  danger  of  haste  is  too  great  for  the  mother. 
An  indication  for  delivery  will  not  arise  on  the  part  of  the  mother,  because  we  can

control  tho  hcmorrhaKo  l)y  the  colpcurynter  or  the  brooch.  Groat  homorrhago  and 
collapse  tlo  not  indicate  rapid  delivery;  on  the  contrary,  the  smUlen  emptying  of 
the  uterus  may  add  to  the  shock  ami  turn  the  delicate  balance  against  the  woman. 
In  suchcasesof  severe  hemorrhage  and  shock  the  (|uick('st  and  most  definitive  means 
of  stopping  the  hemorrhage  is  by  version  and  tamponing  tlie  lower  uterine  segm<'nt 
by  the  breech.  One  then  has  the  case  ai)solutely  under  contnjl,  and  now  the  |)a- 
tient  may  be  stimulated  and  her  blood-loss  replaced  with  saline  soluti(jn. 

Since  there  is  no  heuKjrrhage,  there  is  not  the  shadow  of  a  rea.son  for  hurry. 
These  hours  may  be  employed  in  supplying  tlie  woman  with  fluids,  as  saline  solution 
hypodcrmically,  food,  etc.  The  woman  recovers  frcjm  the  slmck  of  her  first  hem- 
orrhage. The  hours  are  also  useful  for  the  jjreparations  for  delivery.  Xo  detail 
should  be  omitted,  and  everything  must  be  gotten  ready  and  rehearsed  before- 
hand, so  that  when  th(»  delivery  is  to  be  made,  not  an  instant's  delay  need  be 
tolerated.  A  complete  set  of  obstetric  instruments  should  be  sterilized,  especial 
provision  ])eing  made  for  the  treatment  (jf  ]>ostpartum  hemorrhage.  Needles,  long 
needle-holder,  vulsella,  specula,  etc.,  for  sewing  lacerations  of  the  cervix  may  be 
needetl,  as  well  as  gauze  and  long  uterine  packing  forceps  for  tamponing  the  uterus. 
CJood  light  and  a  table  on  which  to  place  the  patient  for  (h'livery  should  be  gotten 
ready,  and  ])r()visi()n  made  for  the  resuscitation  of  the  child — tracheal  catheter, 
hot  bath,  hot  towels,  etc  ,  should  be  at  hand. 

The  nurse  prepares  the  douche-bag  for  giving  a  hot  (120°  F.)  injection  of  sterile 
water,  and  sees  that  there  is  a  supply  of  sterile  solutions,  sponges,  towels,  etc.  As 
a  rule,  the  cervix  may  be  sufficiently  ))repared  to  jiermit  delivery,  but  let  me  again 
sound  the  warning — Bcirarc  of  too  hdsty  extraction  through  a  poorlji  dilated  cervix! 
The  laceration  of  the  highly  vascularizetl  cervix  is  one  of  the  most  formidal)le  acci- 
dents the  accoucheur  could  meet.  The  uteroplacental  sinuses  are  so  superficial  that 
a  tear  }  s  inch  dee])  may  lay  one  open.  The  contraction  and  retraction  of  the  lower 
uterin(>  segment  are  ])oor  at  l)est,  and  poorest  in  jilacenta  i)ra'via,  and  this  means  of 
hemostasis  is  not  strong,  so  that  the  cases  of  fatal  hemorrhage  from  even  tiny  tears 
of  the  placental  site  are  easily  explained.  Slowest  possible  delivery  is  to  be  jirac- 
tised.  If  the  head  is  restrained  by  a  tight  cervix,  the  accoucheur  must  not  use  force 
to  extract  it,  but  nuist  courageously  allow  the  infant  to  die.  The  child  is  so  often 
already  lost  that  this  painful  advice  is  seldom  needed.  An  attemi^t  to  let  air  into 
the  child's  lungs  must  be  made  by  pulling  the  vagina  back  \\ith  a  sjx'culum,  and, 
after  cleansing  the  fauces,  depressing  the  jaw  with  the  fingers,  an  expedient  which 
,was  reconnnended  by  Pugh,  in  17o4,  though  not  in  such  cases. 

Should  placenta  prievia  occur  in  a  primiixira  or  in  others,  and  the  cervix  be 
closed  so  that  one  finger  may  not  be  introduced,  the  case  becomes  more  formidable 
still.  For  such  patients  the  vaginal  tampon  and  the  coljieurynter  have  been  recom- 
mended. There  are  real  objections  to  both  on  the  score  of  sepsis  and  inefficiency. 
Unless  the  head  is  firmly  engaged  in  the  pelvis,  the  tampon  will  not  exert  sufficient 
compression  on  the  cervix  and  i)lacenta  against  the  head  to  check  bleeding  in  this 
manner.  Then  the  external  is  converted  into  an  internal  hemorrhage.  The  same 
is  true  of  the  colpeurJ^lter.  I  have  never  failed  to  pass  the  colpeurynter  into  the 
uterus,  and  I  never  use  the  tampon  except  jirovisionally,  during  the  trans|)ortation 
of  the  i)atient,  or  while  other  i)reparations  are  being  completed.  It  is  for  the.«<e 
cases  that  cesarean  section  has  been  reconnnended. 

Treatment  During  the  Third  .s'/f/f/c— Many  patients  have  been  lost  at  this  point, 
ha\nng  been  skilfully  carried  through  the  two  other  stages.  It  is  neces.sary  to  .save 
blood  with  (>very  m()V(>.  As  soon  as  the  child  is  delivered,  as  in  cesarean  section, 
it  is  hamh'd  to  a  competent  a.ssistant.  the  ojierator  devoting  all  his  attention  to  the 
mother.  Even  a  moderate  hemorrhage  now  demands  the  immediate  removal  of  the 
placenta.  Since  contractitm  ami  retraction  of  the  bed  of  the  placenta  are  imperfect, 
and  especially  since  its  structure  may  be  pathologically  alteretl,  the  delivery  of  the 


460      THE  PATHOLOGY  OF  PREGNANCY,  LABOR,  AND  THE  PUERPERIUM 

placenta  is  slow  and  adherences  may  be  met  with,  some  of  which  are  so  tough  that 
the  finger  cannot  break  them.  As  soon  as  the  placenta  is  removed  the  uterus  usually 
contracts  strongly  antl  Ijleeding  ceases.  Watch  closely,  pulling  open  the  vagina  with 
a  speculum  to  see  if  blood  continues  to  escape  from  the  cervix,  and  if  it  does,  tampon  the 
whole  uterovaginal  tract  firmly.  Waste  no  precious  seconds  on  uncertain  methods 
of  hemostasis,  but  in  the  presence  of  such  urgent  sjnnptoms  use  the  most  radical  and 
definitive  means  we  have.  During  the  ten  to  twenty  seconds  while  waiting  for  the 
gauze  hold  the  uterus  securely  in  forced  anteflexion  (Fig.  718).  (See  Treatment  of 
Postpartum  Hemorrhage,  p.  775.) 

In  placenta  pra?via  a  tiny  laceration  may  give  rise  to  a  fatal  bleeding.  The 
soft,  vascularized  cervix  is  difficult  to  hold  for  suturing,  and  it  may  be  impossible 
to  sew  up  a  laceration  or  to  sew  it  up  quickly  enough  to  save  an  already  exsangui- 
nated woman.  In  suturing  a  laceration  of  the  cervix  it  is  necessary  to  expose  the 
field  thoroughly  liy  Inroad  retractors  (Fig.  689).  The  lips  are  grasped  with  the 
vulsellum  forceps,  and  the  tear  l)rought  within  reach  of  the  needle.  Usually  the 
field  is  so  flooded  with  blood  that  it  is  impossible  to  see  where  to  sew.  A  bullet 
forceps  maj'  be  laid  temporarily  on  each  side  of  the  uterus,  seeking  to  secure  the 
uterine  arteries  in  the  bases  of  the  broad  ligaments  (Henkel).  In  one  such  case  I 
packed  the  uterus  and  the  rent  in  the  broad  ligament  firmly  with  gauze,  thus  stop- 
ping the  furious  flow,  after  which  the  lips  of  the  cer\dx  were  united  over  the  tampon, 
thus  closing  up  the  uterus  entirelj'  (Fig.  725) .  The  vagina  was  snugly  packed  with 
dry  cotton,  to  exert  count erpressure.  The  sutures  were  removed  the  next  day  and 
the  gauze  two  days  later.     The  patient  recovered. 

Before,  during,  and  after  delivery  in  cases  of  placenta  prsevia  it  is  often  neces- 
sary to  treat  the  anemia.  If  the  mother  has  lost  much  blood,  give  her  saline  solu- 
tion under  the  skin,  not  per  rectum,  as  this  interferes  with  the  asepsis  of  the  local 
treatment.  When  the  bowels  are  moving  over  the  field  of  operation,  it  may  be  im- 
possible to  avoid  carrying  the  discharges  into  the  uterus.  Saline  solution  is  to  be 
given  even  if  the  hemorrhage  is  going  on,  as  then  the  patient  does  not  lose  pure 
blood,  but  blood  mixed  with  salt  solution.  We  do  not  wait  for  fainting  to  stop  the 
hemorrhage  in  placenta  prsevia.  The  author  has  administered  a  gallon  of  saline 
solution  under  the  skin  and  it  was  absorbed  as  fast  as  it  could  be  injected,  and,  after 
the  local  treatment  of  the  case  was  completed,  two  quarts  more  per  rectum,  with 
success.     Such  large  amounts  are  seldom  required. 

Other  Methods  of  Treatment. — Accouchement  force,  the  rapid  dilatation  of  the 
cervix,  tearing  and  cutting  it,  if  necessary,  followed  by  the  immediate  delivery  of  the 
child,  has  no  place  in  the  treatment  of  placenta  praevia.  The  author  believes  it  is 
almost  criminal,  and  it  is  opposed  to  all  recognized  principles  of  treatment.  The 
results  condemn  it,  and  Kerr  says,  judging  from  mortalities,  it  is  the  worst  of  all 
methods.  Treub  retracts  his  recommendation  of  it,  saying  that  his  mortality  was 
18.25  per  cent,  for  the  mothers  and  48  per  cent,  for  the  children.  IMiiller  showed 
44  per  cent,  maternal  mortality  and  ()2.7  per  cent,  for  the  children.  Gentle  dilata- 
tion is  wanted,  for  even  the  soft-rubljcr  bag  may  rupture  the  cervix  unless  properly 
handled. 

The  same  may  be  said  of  Bossi's  branched  powerful  steel  dilator  and  of  the 
others  of  the  class. 

Separation  of  the  placenta,  or  its  rcmioval  ])eforc  delivery  of  the  child  (Simpson, 
1840),  is  obsolete.  Miller,  of  Pittsburgh,  ligated  the  uterine  arteries  in  11  cases, 
saving  the  first  and  last  eight  of  them. 

Cesarean  section,  first  performed  by  Tait,  is  gradually  gaining  reluctant  recog- 
nition. Especially  favored  by  American  surgeons  and  gynecologists,  it  was  con- 
demned by  American  and  I^^uropean  obstetricians, — Ehrenfest,  Hirst,  Holmes, 
Schauta,  Hofmeier,  Ahlfeld, — but  very  recently  the  operation  has  begun  to  enjoy 
more,  and  I  think  just,  popularity.     Williams  and  Edgar  give  it  qualified  approval, 


PLACflNTA    I'RiEVIA  461 

Scllhcim,  Kninip;,  Pankov,  P.  Dudley,  Fry,  Donoghuo,  Zinkc.  Kerr,  Laptliorn 
Sniitli,  Bar,  Hccascns  (Madrid)  rcfuimnend  it — of  course,  in  wcll-clioscn  cases.  At 
the  meeting  of  the  American  Gynecologic  Society,  April,  1909,  the  subject  was 
thoroughly  handled,  and  while  the  opinions  were  divided,  a  perusal  of  the  transac- 
tions is  convincing  that  cesarean  section,  in  the  hands  of  the  <'xpert  abdominal 
operator,  is  a  valuable  addition  to  our  treatment.  Cesarean  section  hius  a  general 
mortality  of  4  per  cent,  in  favorable  cases;  it  should  be  no  more  than  this  in  favor- 
able cases  of  placenta  previa,  and  there  is,  in  addition,  the  reduction  of  th(?  infant 
mortality  from  50  to  5  per  cent.  Placenta  ])rapvia,  under  the  usual  methods,  sIkjws 
at  best  4  per  cent,  mortality,  and  its  treatment  entails  great  anxiety,  nmch  loss  of 
time,  and  refjuires  exceptional  ol)stetric  skill  to  save  b(jth  m(4her  and  child.  In 
the  isthmial  variety,  where  the  i)lacenta  is  implanted  squan-ly  over  the  int<'rnal  os 
andliangslike  a  festoon  aboveit,thematernalmortalityis  so  high  that  the  abdominal 
delivery  is  strongly  the  method  of  choice.  Without  going  further  into  the  di.«<cus- 
sion,  I  will  state  my  jjosition:  an  intlication  for  cesarean  section  will  arise  in  cases 
of  central  and  of  partial  placenta  pra^via,  when  the  pregnancy  is  at  or  near  term, 
with  a  living  child,  the  mother  in  good  condition,  the  cervix  being  clo.sed  or  promis- 
ing difficulty  in  dilatation,  conditions  most  common  in  primipara\  A  neces.sary 
recjuirement  also  is  that  the  asej^tic  facilities  of  a  good  maternity  can  be  had,  or 
improvised  at  home,  and  a  man  capable  of  his  task  is  obtainable.  The  ojjport uni- 
ties for  performing  the  abdominal  deliver}'  with  all  these  conditions  filled  will  Ix* 
quite  rare. 

In  the  exigencies  of  general  practice,  and  in  the  usual  l)ad  surroundings  in 
which  these  cases  come  to  the  accoucheur,  it  is  found  that  the  best  method  of  treat- 
ment is  Braxton-Hicks'  version  and  verj-  slow  spontaneous  delivery.  Xe.xt  comes 
the  metreurynter. 

Vaginal  cesarean  section  was  performed  by  Diihrssen  and  is  recommended  by 
Bumm  for  ])lacenta  prirvia.  It  is  condemned  by  most  writers,  among  whom  are 
Kerr,  Spencer,  Peterson,  Newell,  Hofmeier,  Hannes.  I  have  done  it  once  with  suc- 
cess, when  the  placenta  was  low  in  the  uterus  and  had  ])artly  separated,  but  believe 
that  the  operation  is  not  to  be  recommended  in  the  treatment  of  placenta  praevia. 

Very  recently  extraperitoneal,  suprasymphyseal  cesarean  section  has  been  ad- 
vocated for  these  cases  (Sellheim).  The  author  has  no  experience  with  the  opera- 
tion, but  from  ]nil)lished  reports  believes  that  the  indication  will  receive  scant 
recognition.

CHAPTER  XXXV 


MULTIPLE  PREGNANCY 


Placing  this  subject  in  the  pathologj^  of  pn^gnancy  might  eHcit  comment,  but 
the  succeeding  pages,  showing  the  frequency  of  maternal  disease  and  of  fetal  death, 
will  prove  that,  in  the  human  female,  having  more  than  one  offspring  at  a  time  is 
distinctly  abnormal.  It  is  an  atavistic  reversion,  and,  in  general,  such  reversions 
are  abnormal.  Twins  occur,  acconling  to  Guzzoni,  who  studied  over  50,000,000 
births,  once  in  87  cases,  triplets  once  in  7103;  quadruplets  once  in  757,000;  quin- 
tuplets once  in  41,600,000  births.  Over  30  cases  of  quintuplets  have  been  reported. 
^^assali  reports  an  authentic  case  of  sextuplets,  at  Lake  Lugano,  there  being  de- 
livered at  the  fourth  month  two 
female  and  four  male  children 
with  a  total  weight  of  1730  gm. 

The  frequency  of  multiple 
pregnancy  varies  Avith  the  fertil- 
ity of  the  people  (Peuch,  1873), 
and  the  fertility  varies  in  different 
countries  and  at  different  periods; 
thus  in  Ireland  and  Russia  twin 
births  are  commoner  than  in 
France,  where  the  birth-rate  is 
low. 

Multiparse,  especially  those 
giving  birth  frequently,  are  more 
likely  to  have  twins,  and  the  prob- 
ability increases  after  the  age  of 
thirty-three  years  in  both  par- 
ents. A  hereditary  disposition 
is  certain,  and  the  tendency, 
while  usually  transmitted  by 
the  mother,  may  also  be  given 
through  the  father.  It  is  also 
noted  in  the  lower  uniparous  ani- 
mals, for  example,  the  cow  (Dun- 
can) .  Marriage  of  twins  increases 
the  potency  of  the  hereditary  im- 
pulse. Twins  and  triplets  are 
lik(>ly  to  be  repeated  in  the  same 
family.  Cases  of  unusual  fertility  are  not  rar(\  ( Jeisk^r  tells  of  a  woman  physician 
(Mary  Austin)  who,  in  thirty-three  years'  wedlock,  had  13  twin  and  6  triplet  births, 
a  total  of  44  children,  her  sisters  having  41  and  26  children  res]X'ctively  (Strassman). 
Sue  tells  of  a  Parisian  whose  wife  bore  him  21  children  in  seven  years,  and  who 
seduced  a  servant  who  then  delivered  triplets. 

Causation. — (Jenerally,  two  kinds  of  twins  are  distinguished,  those  coming 
from  separate  and  distinct  ova  and  those  from  one  ovum.  Two  eggs  escai)ing  from 
an  ovary  at  the  same  time  may  l)e  fertilized  and  develop  synchronously  in  the  uterus. 
These  eggs  may  even  come  out  of  the  same  Graafian  follicle,  since  such  follicles,

and  ovon  some  containing  tlir('(>  eggs,  havo  frequently  l)een  seen.  Each  ovary  may 
furnish  one  of  the  ova.  When  two  or  more  separate  ova  locate  in  the  uterus,  we 
ha\c  distinct  o\'ular  formations  dcNcloping  side  hy  side  (Fig.  411>).  If  the  ova  locate 
far  fnjni  eacii  other,  tw(j  distinct  placentas  develop;  if  near  each  other,  the  two  i)la- 
centas  fuse,  but  their  circulations  do  not  (Schatz).  Since  in  such  cases  each  cliild 
has  its  own  amnion  and  chorion,  where  the  memhranes  lie  appcjsed  a  septum  will 
he  found  made  up  of  four  layers — an  anmi(jn  and  a  choricjn  for  each  fetus.  ( )cca- 
sionally  decidual  remnants  will  he  found  in  the  septum,  the  relics  of  the  deciduae 
capsulares  or  reflexa'  of  the  early  stages  of  the  develo])ment  of  the  ova.  Theoreti- 
cally, one  might  insist  on  finding  six  layers  in  the  septum  of  tlouble  ovum  twins — 
two  decichue,  two  chorions,  and  two  anmions. 

The  etiology  of  twins  from  one  <)\-uni,  calleil  honiohigous,  or  nionoeliorionic, 
is  still  a  mystery.  Aristotle  knew  that  two  emhrycjs  could  come  from  an  egg  with 
two   yolks,    and    three    embryos 

have  been  found  in  one  egg.    Two  — r — 

nuclei    have    been    found    in    one  "  -_  - --~""^.  _-^ 

yolk,  and  KoUiker,  Stiickcl,  and 
von  Francjue  found  double  ger- 
minal vesicles  in  the  human  egg. 
If  such  an  ovum  is  to  be  fertil- 
ized, two  i^olar  bodies  must  first 
be  extruded,  and  two  spermato- 
zoids  are  needed  for  fertilization, 
which  theoretically  is  iKjt  impos- 
sible, but  then  we  would  have 
two  chorions  developetl  and  the 
findings  would  be  the  same  as  if 
two  difTerent  eggs  had  been  ini- 
j^regnated.  Perhaps  we  shall 
learn  hereafter  that  such  an  (jc- 
currence  has  been  proved.  An- 
other theory  is  that  on  one 
germinal  vesicle  two  primitive 
streaks  develop,  that  is,  double 
gastrulation  occurs.  Two  sper- 
matozoids  entering  tlu'  ovum 
])r(jbably  cannot  protluce  this 
condition,  because  ova  fertilized 
in  this  way  usually  die. 

If  the  two  embryonal  si)ots 
develoj)  close  to  each  other,  it 
is  possible  that  one  amnion  will 

inclo.se  the  two  fetuses;  if  far  fnjm  (>ach  other,  each  fetus  will  have  a  separate 
amnion  ("Fig.  420).  The  older  writers  held  that  always  two  anmions  developed, 
but  that  the  septum  atrophied  and  disai)i)eare(l.  Only  about  40  ca."^es  are  on 
record  of  twins  without  a  septum  between  the  two  sacs,  that  is,  lying  in  one 
amniotic  cavity.  Should  the  separation  of  the  two  embryonal  areas  be  incomplete, 
a  doubl<>  monster  will  result  (Sobotta);  therefore,  according  to  the  th(K)ry  that 
homologous  twins  are  the  result  of  the  fission  of  the  embryonal  area  into  two  i)arts, 
and  their  separate  develoiMnent  into  fully  formed  fetuses,  we  nuist  conclude  that 
double  monsters,  like  the  Siamese  twins,  are  the  result  of  incomplete  fission  and  not 
of  fusion.  A  mon.ster  with  four  legs  would  mean  fis.sion  at  the  lower  pole,  and  one 
with  two  h(>a(ls  fission  at  the  cej^halic  i)ole  of  the  embryonal  area.  It  is  regretai)le 
that  we  have  little  scientific  foundation  for  the.se  plausible  theories.

THE  PATHOLOGY  OF  PRECXANXY,  LABOR,  AND  THE  PUERPERIUM 


Characteristics. — The  placenta  in  iniioval  twins  is  always  single;  there  are 
usually  two  ctn-ds,  l)ut  rarely  only  one  which  ])ifurcates  near  the  fetuses,  and  these 
are  monoaniniotic  ova;  the  blood-vessels  anastomose  on  the  surface  of  the  jilacenta, 
and  also  in  the  villi  themselves,  i)roducing  a  third  or  intermediate  circulation  ])e- 
tween  the  twins.  The  septum  of  the  placenta  never  shows  traces  of  decidua,  and 
only  two  layers,  the  two  amnions,  can  be  found  in  it.  The  children  are  said  to  ho 
very  much  ahke  in  size  and  in  mental  and  physical  characteristics,  but  the  author 
has  not  found  this  to  be  constant.  Unioval  twins  are  rare,  Ahlfeld  in  11.57  cases 
finding  only  15.55  per  cent. 

Triplets  and  even  quadruplets  may  come  all  from  one  ovum,  but  usually  two 
ova  are  concerned,  one  of  which  may  bring  forth  two  fetuses. 

In  length  and  weight  twins  usually  differ  more  or  less,  4  cm.  and  2200  gm. 


Fig.  421. — Acardi.^cus  Amorphcs.     (Northwestern  L^niversity  Medical  School  specimen.) 


being  the  limits  respectively.  Twins  are  usually  smaller  than  single  children,  but 
the  combined  weight  is  greater.  The  same  proportion  of  boys  and  girls  obtains 
with  twins  as  in  general.  Twins  from  one  ovum  are  smaller  than  those  from  two, 
and  the  difference  in  weight  is  not  so  great;  also  they  have  a  higher  mortality  and 
are  more  often  deformed.  The  same  deformity  often  exists  in  both  twins,  as  in 
one  of  the  author's  cases,  double  harelip,  and  one  of  C.  E.  Black,  rudimentary  colon. 
It  is  said  the  tendency  to  this  form  of  twins  is  not  hereditary  (Strassman).  Eclamp- 
sia is  more  common  with  unioval  twins.  Homologous  twins  are  always  of  the  same 
sex.  The  two  circulations  anastomose  in  the  conmion  jilacenta,  artery  to  artery,

who,  therefore,  advised  the  tying  of  the  cord  of  the  first  child  delivered  to  prevent 
the  other  from  bleeding  through  tlu;  open  vessels.     As  a  result  of  this  arrangement

water,  or,  what  is  just  as  good,  sterile  boric-  soluticjn.  L'niess  there  is  s<jine  irrita- 
tion or  infection  of  the  eyes,  they  do  not  need  any  treatment.  The  nurse  is  to  he 
instructed  to  report  at  once  by  telephone  or  messenger  the  first  sign  of  inflannnation 

of  the  (•(ilijlllictiva. 

The  Bowels. — The  author  recommends  the  routine  administration  of  10  droi)s 
of  castor  oil  to  the  infant  on  tlie  day  after  the  day  of  birth.  This  evacuates  the 
meconium  and  any  matters  swallowed  during  delivery,  and  does  nmch  to  prevent 
colic.  Later  an  occasional  repetition  of  the  dose,  and  .salt  solution  colonic  flush- 
ings, given  with  a  funnel  attached  to  a  s(jft-rubl>er  catheter,  will  keep  the  intestinal 
tract  in  order.  Tiie  mouth  and  tongue  are  not  cleansed  unless  re(|uired,  and  then 
with  gentleness,  to  avoid  rubbing  off  the  dc^licate  epithelium.  Wounds  thus  pro- 
duced may  form  the  atrium  of  infection,  esix'cially  at  the  pillars  of  the  fauces 
(Bednar's  aphtha?).  Excoriation  of  the  anal  region  seldom  occurs  with  brea.st- 
feeding,  but  is  usual  with  bottie-feeiling.  Aljsolute  cleanliness  of  the  parts,  fre- 
quent change  of  the  diai)er,  the  invarial)le  use  of  waslied,  well-rinsed,  and  ironed 
diapers,  cool  ablutions,  avoidance  of  friction,  moderate  use  of  du.sting-powders, 
a.s  stearate  of  zinc,  \v\\\  do  much  to  prevent  and  cure  the  intertrigo,  but.  best  of 
all,  will  be  the  jirocuring  of  a  proper  food  for  the  infant. 

Urination.  If  the  infant  does  not  urinate  within  twelve  hours,  the  i)arts  are 
to  be  examined  for  congenital  deformity.  A  tight  prepuce  is  almo.st  never  the  cause. 
Either  the  infant  has  not  had  enough  water  or  food,  or  it  pa.s.ses  water  unobserved 
in  its  l)ath,  or  lias  an  attack  of  renal  congestion,  perhaps  even  nephritis.  In  such 
cases  uric-acid  infarct  is  usually  found.  Sepsis  may  also  cause  aimria,  also  absorj)- 
tion  of  toxins  from  the  bowel  and  all  febrile  affections.  The  treatment  is  on  general 
lines — free  catharsis,  administration  of  much  water,  moderate  use  of  mother's 
milk,  warm  fomentations  over  the  bladder  and  kidneys,  a  sitz-bath,  a  prolonged 
colonic  flushing,  and,  finally,  the  catheter.  The  author  had  one  ca.se  where  a  female 
child,  apparently  healthy,  passed  no  urine  for  three  days.  Catheterization  brought 
a  few  drams  of  thick,  highly  colored  urine,  after  which  the  function  became  normal. 
The  l)rick-dust  .sediment  in  the  urine  and  on  the  diapcT  consists  of  uric-acid  crystals 
or  ammonium  urate.  They  may  cause  pain  during  voiding  and  they  indicate  the 
need  of  more  water. 

The  Feeding. — Eight  to  twelve  hours  after  birth  the  child  is  jiut  to  the  l»reasts, 
as  usually  by  this  time  the  mother  has  rested.  Thereafter,  until  the  milk  comes  in, 
the  infant  nurses  every  four  hours,  and  then  every  three  hours  for  the  first  two  weeks, 
after  which  the  pcTiod  is  lengthened  to  three  and  one-half  hours.  No  attempt  is 
made  to  sterilize  the  child's  mouth  by  washing,  because  it  is  im])ossible  and  harm- 
ful, and  invites  the  infection  it  seeks  to  avoid.  The  nursing  la.sts  ten  to  fifteen 
minutes,  and  the  nurse  mu.st  be  sure  that  the  infant  really  .swallows  the  milk.  It 
is  occasionally  necessary  to  give  water  between  the  feedings,  but  the  nurse  is  tol>e 
advised  of  the  uselessness  and  dangers  of  the  hal)it  of  water-tijipling.  Th<'  child 
really  needs  little  extra  licjuid.  If  the  child  does  not  take  the  breast  willingly,  an 
investigation  may  reveal  a  jioorly  shaped  nipple,  a  too  full  brea.st,  difficult  flow  of 
milk,  milk  that  does  not  agree  with  the  child,  and  which  it  instinctively  refu.ses,  salty 
or  bitt(T  milk,  or,  finally,  there  may  be  none  in  the  breast.  Much  patience  is 
required  to  teach  the  infant  how  to  suck,  and  wide  difT(Tences  exist  in  the  capa- 
bilities of  nurs(»s  to  do  this.  If  there  is  any  doubt  of  the  child  getting  enough 
nourishment,  it  should  be  weighed  before  and  after  each  fee<ling. 

For  the  first  few  days  wat«T.  an  ounce  every  two  hours,  and  the  colo.strum  from 
the  breasts  usually  suffice  for  the  wants  of  the  infant,  but  if  it  should  cry  from 
hunger,  a  dram  of  cream  to  an  ounce  of  water  or  a  vctv  weak  milk  of  "peptogenic 
powder"  may  be  given.  In  ho.spitals  the  infant  may  «)btain  an  occasional  feeding 
from  one  of  the  other  motluTs  until  its  own  mother  has  milk.  The  iM)ssil)ility  of 
the  contagion  of   syphilis  in  maternities  nuist    never  be  forgotten.     The  author

is  very  skeptical  regarding  the  "starvation  fever"  so  often  mentioned  as  occurring 
at  this  period.  Probably  most  of  such  temperatures  are  due  to  infection^intes-

Without  doubt  the  best  food  for  the  infant  comes  from  its  mother's  breasts, 
and  if  she  be  absolutely  unable  to  nurse,  before  employing  artificial  food  a  wet- 
nurse  should  be  obtained.

history  sheet,  the  same  as  for  the  mother. 

General. — \  quiet,  undisturbed,  ordered  life  is  to  be  provided  the  new  indi- 
vidual, as  habits  formed  now  are  permanent.  Plenty  of  fresh  air  is  as  neeessiiry 
for  tlie  infant  as  for  the  adult,  and  without  doubt  most  babies  are  cuddled  too  much. 
It  should  sleep  in  a  room  with  a  temperature  of  from  G8°  to  72°  F.,  and  for  the  first 
few  weeks  its  eyes  should  be  protected  from  bright,  glary  light.  It  is  not  to  be  dis- 
turbed except  for  attentions  to  itself,  and  when  being  lifted,  should  be  guarded 
against  injury.  The  mirse  nnist  be  instructed  not  to  let  the  nursling  get  into  bad 
habits — water-tippling,  jx'ppermint-water  tippling,  whisky  and  water  and  creme-<le- 
menthe  tippling,  sucking  on  the  finger,  nursing-bottle,  or  nipple,  sleeping  with 
mother,  being  taken  up  when  it  (Ties,  (jr  nx-ked,  held,  and  carried  except  when  sick. 
By  propiT  training  the  child  can  be  taught  regular  habits,  t(j  slee|)  all  night  and  be- 
tween nursings,  and  to  cry  only  when  hungry,  uncomfortable,  or  sick. 

During  his  professional  visit  the  physician  pays  some  attention  to  the  infant 
also.  He  must  especially  discover  the  first  signs  of  malnutrition,  because,  unless 
this  is  early  remedied,  structural  changes  occur  in  the  intestinal  mucosa  and  the 
general  system  which  may  leave  an  impress  for  bad  on  the  child's  whole  life.  This 
is  the  reason  the  author  insists  .so  strongly  on  the  wet-nurse  when  the  mother  can- 
not nourish  h(T  offspring.  The  physician  watches  the  physiologic  changes  which 
adapt  the  child  to  extra-uterine  existence,  and  decides  each  day  if  they  are  pro- 
ceeding normally.     The  condition  of  the  navel  claims  his  special  attention. 

Summary  of  the  Care  of  the  Infant 

1.  Asepsis  and  antisepsis  of  the  navel,  eyes,  and  orifices  of  the  body. 

2.  AVatching  for  evidences  of  sickness. 

3.  Attention  to  emunctories — bowels,  kidneys,  and  skin. 

4.  PVeding  and  nutrition. 

5.  The  healing  of  the  navel.

PART  II 

THE  PATHOLOGY  OF  PREGNANCY,  LABOR,  AND  THE 

PUERPERIUM 


CHAPTER  XXVI 
THE  PATHOLOGY  OF  PREGNANCY 

It  would  be  surprising  if  a  function  which  causes  such  marked  general  and  local 
changes  as  gestation  does  should  be  completed  without  the  production  of  conditions 
that  might  be  considered  i)athologic.  Pregnancy  does  not  confer  immunity  against 
any  disease;  on  the  contrary,  it  makes  the  woman  susceptible  to  certain  general 
diseases,  and  almost  always  aggravates  existing  general,  and  especially  local, 
affections.  Only  seldom  do  we  hear  that  patients  feel  better  during  pregnancy: 
the  majority  suffer  more  or  less  discomfort.  Many  conditions  formerly  classed 
as  normal  are  now  called  pathologic. 

The  affections  of  pregnancy  are  broadly  divided  into  those  of  the  mother  and 
those  of  the  ovum.  Of  diseases  of  the  mother,  two  grand  divisions  are  made — 
the  general  and  the  local,  the  latter  taking  in  all  the  affections  of  the  uterus,  decidua, 
vagina,  etc.  Both  general  and  local  diseases  may  be  classified,  first,  as  to  whether 
they  are  only  morbid  exaggerations  of  conditions  natural  to  normal  pregnancy — 
that  is,  they  are  incidental  to  pregnancy,  are  disorders  of  pregnancy;  and,  second, 
as  to  whether  the  diseases  are  accidental  complications,  either  preexistent  or  de- 
veloped during  pregnancy.  The  general  diseases  incident  to  pregnancy  are  most 
likely  to  be  disorders  of  those  functions  most  concerned  by  gestation,  for  example, 
the  general  metabolism,  the  liver  and  kidneys,  the  blood.  Examples  of  accidental 
diseases  are  smallpox,  tuberculosis,  and  syphilis. 

Local  diseases  incident  to  pregnancy  manifest  themselves  in  pathologic  in- 
crease of  the  congestion  of  the  parts,  al^normal  tissue  growth,  deformation  of  the 
uterus,  displacements,  unusual  location  of  the  ovum,  etc.  Of  diseases  of  the  ovum, 
we  must  consider  those  of  the  child  and  those  of  the  fetal  envelops,  the  chorion, 
the  amnion,  the  placenta. 

Most  of  the  diseases  of  the  mother  and  child  have  close  relations- — one  can 
hardly  ))e  ill  without  affecting  tii(^  other.  A  great  many  general  diseases  have  local 
manifestations  in  the  genitalia,  and  many  diseases  accidental  to  pregnancy  aggra- 
vate the  affections  incidental  to  pregnancy.  The  reader  may  thus  appreciate  the 
difficulties  of  making  a  classification  of  them  and  adhering  to  it  in  the  subsequent 
discussion  of  the  subjects.

Naturally,  in  a  work  of  this  size  it  will  be  impossible  to  treut  all  th<'  above 
affections,  nor  will  tiie  scheme  Iktc  given  be  strictly  followed.  I)isea.ses  duplicated 
under  different  headings  will  be  considered  together — for  example,  .syphilis  of  the 
mother,  of  the  child,  of  the  placenta,  and  of  the  decidua  will  be  treated  as  one  sub- 
ject. The  author  also  c(jnsi(l(Ts  it  best  to  treat  a  tlisease  which  atTects  pregnancy, 
labor,  and  the  puerp(Tium  consecutively  in  a  single  chapt(T,  rather  than  to  discu.'^.s 
it,  as  it  influences  each  stage  separately,  in  three  ditlerent  parts  of  the  volume. 


CHAPTER  XXVII 
THE  TOXEMIAS  OF  PREGNANCY 

Toxemia  is  a  term  which  has  obtained  very  general  usage,  though  little  is 
positiveh'  known  about  the  conditions  it  represents.  It  means  that  the  blood 
contains  toxins  or  poisons  of  an  alkaloidal  nature,  leukomains,  or  substances  similar 
to  these.  These  toxins  are  supposed  to  be  the  result  of  deficient  or  abnormal  general 
metabolism,  or  morbid  processes  occurring  in  special  organs,  as  the  liver,  the  kid- 
neys, the  thyroid;  again,  the  poisons  are  supposed  to  come  from  the  fetus  or  the 
placenta,  from  abnormal  chemism  occurring  here.  As  a  result  of  the  deficient 
action  of  some  organs  of  the  l)ody,  for  example,  the  liver,  the  kidneys,  the  thjToid, 
and  perhaps  others  of  the  ductless  glands,  these  poisons  are  retained  in  the  body, 
or  they  are  not  sufficiently  oxicUzed  or  changed  so  as  to  be  rendered  harmless  and 
eliminable  by  the  emunctories. 

Such  is  the  theory,  and  to  explain  whj^  and  how  these  changes  originate  we 
have  other  theories.  Many  authors  believe  that  every  pregnancy  is  attended  by 
an  auto-intoxication,  due  to  the  mighty  changes  in  the  general  metabolism  incident 
to  the  condition,  the  active  chemism  required  for  the  transfer  of  materials  for  the 
growi:h  of  the  fetus,  the  presence  in  the  maternal  blood  of  the  waste  of  the  child, 
the  by-products  of  the  exaggerated  eliminative  action  of  the  special  organs,  liver, 
kidneys,  spleen,  etc. 

The  constitution  of  a  perfectly  healthy  woman  might  meet  all  these  demands 
without  any  external  s>Tnptoms  or  signs  of  disease,  ])ut  such  individuals  are  very 
rare,  and,  therefore,  evidences  of  impaired  function,  of  toxemia,  are  quite  common. 
Predisposing  elements  for  toxemia  are  neurasthenia,  anemia,  vicious  heredity, 
especially  one  of  toxic  neuroses,  antecedent  liver,  kidney,  th}Toid,  intestinal,  or 
other  organic  disease.  Insufficient  internal  secretion  by  the  ovary  has  been  cited 
as  a  cause.  Intestinal  auto-intoxication  is  generally  admitted,  and  perhaps  the 
liver  here  is  at  fault,  not  arresting  nor  elaborating  the  absorbed  poisons  as  it  should. 

Veit  says  the  transportation  and  dissolution  of  s\Tic\'tial  elements  of  the  placenta  produce 
syncytio-toxins,  which,  if  not  properly  met  by  antibodies  in  the  patient's  blood,  act  injuriously. 

Experiments  by  Engelman  and  Frankcl  have  shown  that  the  placenta  contains  thrombo- 
genic  ferments  which  are  rapidly  fatal  to  rabbits,  but  that  when  these  are  neutralized  by  hirudin 
(leech  extract),  the  juice  of  the  placenta  is  non-poisonous. 

Bacterial  action  is  also  said  to  cause  the  toxemia — plausible,  but  lacks  proof.  Albert  be- 
lieves that  endometritis,  infective  in  origin,  produces  toxins  which,  absorbed,  may  cause  toxemia, 
hyperemesis,  and  even  eclampsia.     Some  cases  seem  to  favor  belief  in  this  theory. 

The  name  of  Bouchard  is  most  often  associated  with  these  sttidies  on  autointoxication,  for 
he  has  done  a  great  deal  of  work  on  the  subject.  He  sought  to  prove  a  relation  between  the  toxi- 
city of  the  blood  and  of  the  urine — deficient  excretion  showing  increase  in  the  former.  Animals 
into  which  filtered  urine  of  pregnant  women  was  injected  had  convulsions  and  died,  autopsy  show- 
ing the  .same  conditions  observed  in  the  human. 

Later  experiments  disproved  these  assumptions.  Pinard  and  Bouffe  de  St.  Blaise  ascribed 
the  symptoms  to  a  hepatotoxemia. 

We  have  as  yet  verj'  few  scientific  facts  on  which  to  base  all  these  hypotheses, 
but,  while  desirable  for  practice,  it  is  not  unconditionally  necessary  to  have  every 
theory  proved.  The  general  applicability  is  sometimes  proof  itself.  We  recog- 
nize many  groups  of  symptoms  which  can  Ix'  most  satisfactorily  explained  by  this 
theory  of  toxemia,  and  treatment  directed  in  appropriate  lines  is  successful  in  re- 
lieving the  conditions.  Some  of  the  affections  bear  resemblance  to  certain  phe- 
nomena explained  as  being  anaphylactic.

Symptomatology. — Two  groups  of  symptoins  may  I x*  distinguished — the  mild 
and  the  severe,  liut  trMUsition  forms  an*  common. 

As  mild  toxemias,  many  of  the  minor  complaints  of  pregnancy  may  be  classed. 

The  XervoH.s  .S'j/^/em.— Headache,  dizziness,  In-perexcitability,  lassitutle,  ten- 
dency to  melancholia,  exaggerati(jn  of  reHexes,  nmscular  twitchings,  cramps  in  mus- 
cles, neuralgias,  neuritis,  aljerrations  of  the  special  senses,  as  of  taste  (pica),  of  sight 
(restricted  vision),  and  of  smell. 

The  Skin. — Edema,  pruritus,  pigmentation,  various  eruptions,  for  example, 
herpes,  pruriginoid  lesions,  acne,  red  nose.  Clraver  symptoms  will  he  considered 
later. 

Digestirc  Canal. — Nausea,  vomiting,  constipation,  colic. 

Circulatory  System. — Palpitations,  syncope,  varices,  enlarged  thyroid,  symp- 
toms resembling  "formes  frustes"  of  Ba.sedow's  disease,  anemias. 

Respiratory  N/y.s/cm.— Cough,  asthmatic  attacks. 

Bones. — The  puerperal  osteojihytes,  softening  of  the  bones,  similar  to  osteo- 
malacia, pains  in  the  bones,  perhaps  due  to  alteration  in  the  hematopoietic 
system  (?). 

The  Urinary  System. — The  kidney  of  pregnancy  (Leyden),  albuminuria, 
oliguria,  decreased  urea  output. 

Cleneral  examination  of  the  patients  will  usually  show  the  evidences  of  deficient 
excretion,  pasty  or  muddy  skin,  even  subicterus,  \\-ith  perhaps  an  odor;  drv', 
coated  tongue,  reddened  gums,  pulse  of  low  tension  y  tj-mpany,  tender  liver,  and 
urinary  fincHngs.  Tiie  pathologic  anatomy  of  these  toxemias  has  never  been 
studied  because  they  are  not  fatal.  The  severer  toxemias  have  l)een  much  investi- 
gated, and  we  may  deduce  from  such  findings  the  probable  conditions  in  the  milder 
foruLS. 

The  treatment  of  mild  toxemias  is  symptomatic  and  general,  tlirected  toward 
the  increase  of  elimination,  restriction  of  nitrogenous  food,  antl  hygienic  living. 
Prevention  of  the  graver  toxemias,  the  hint  of  which  is  contained  in  the  milder 
manifestations,  is  important.  If  the  history,  family  or  personal,  points  to  such 
tendency,  closer  supervision  of  the  gravida  is  needed.  The  consistent  examination 
of  the  urine  throughout  pregnancy  and  the  watchfulness  over  the  patient,  fully 
described  under  the  Hygiene  of  Pregnancy,  will  disclose  tiireatening  dangers  if 
the  rules  laid  down  for  the  guidance  of  pregnant  women  have  not  i)revented  such 
disea.se  altogether. 

The  graver  toxemias  of  pregnancy  are  hyiMTcmesis  gravidarum,  eclampsia, 
hepatic  autolysis  (fulminant  to.xemia),  impetigo  herpetiformis,  etc. 

HYPEREMESIS  GRAVIDARUM 

Nausea  and  vomiting  occur,  in  greater  or  less  degree,  in  half  of  all  pregnant 
women,  and  are  considered  normal.  They  may  be  so  marked  as  to  become  serious 
and  deserve  the  appellation  "pernicious,"  leading  not  seldom  to  abortion  or  ileath. 
or  both.  It  is  difficult,  in  a  given  ca.se,  to  tell  when  the  vomiting  pas.ses  from  the 
normal  to  the  patliologic.  The  disease  has  been  called  the  obstinate,  the  uncon- 
trollable, the  incoercil)le.  vomiting  of  i)regnancy.  but  the  term  hyixTemesis  gravi- 
darum, though  a  hybrid,  is  the  one  generally  u.>^ed. 

Soranus,  of  Ephesus  (20  a.  d.).  observed  the  ili.-^ease.  but  Delorme,  in  the 
nineteenth  century,  called  attention  to  the  danger  of  the  affection.  Sinmiond. 
in  1813,  was  the  first  to  interrupt  pregnancy  as  a  theraixnitic  measure,  and  with 
success.  Paul  Dul)ois.  in  1852.  before  the  French  Academy  oi  Medicine,  pre- 
sented a  thesis  on  the  subject  which  is  still  classic.  It  is  said  that  Charlotte  Bronte 
died  of  this  affection. 

Symptoms. —The  disease  usually  begins  in  the  second,   more  rarely  in  the 


344      THE  PATHOLOGY  OF  PREGNANCY,  LABOR,  AND  THE  PUERPERIUM 

fourth,  month,  but  may  appear  in  the  sixth  month,  though  seldom  after  this,  and 
if  it  does,  one  suspects  nepliritis.  It  lasts  from  six  weeks  to  three  months,  but  may 
take  so  ^^olent  a  course  as  to  be  fatal  in  two  weeks.  It  may  also  intermit  for  a 
few  weeks,  then  recur,  growing  better,  then  worse. 

Dubois  distinguished  three  periods  in  the  sickness,  and  while  clinically  the 
lines  of  separation  are  never  sharp,  such  a  division  of  symptoms  is  useful  for  purpose 
o^  descri]:)tion.  At  first  attention  is  not  called  to  the  gravida  because  nausea  and 
vomiting  are  such  frequent  occurrences  in  the  early  months,  but  when  the  intoler- 
ance of  the  stomach  for  all  liquids  and  foods  becomes  apparent  and  the  patient 
loses  her  appetite,  one  is  forced  to  recognize  that  the  state  of  the  gravida  is  serious. 
The  anorexia  may  become  an  actual  loathing  of  food,  and  nausea,  with  retching, 
may  occur  at  the  mere  mention  or  sight  or  smell  of  it.  Emesis  is  caused  by  a  mere 
change  of  position  of  the  pcn'son,  the  entry  of  another  one  into  the  room,  even  ]:)y  the 
sight  of  the  husband.  It  continues  during  the  night,  robbing  the  distressed  woman 
of  sleep,  and  contributing  to  the  exhaustion  caused  by  the  constant  retching. 
Hiccup  may  be  a  troublesome  symptom,  as  may  pyrosis.  Thirst  is  harassing. 
The  patient  complains  of  a  constant  boring  pain  in  the  stomach  and  of  soreness  of 
the  ribs  and  adjoining  muscles.  Salivation  is  occasionally  a  concomitant;  consti- 
pation is  the  rule,  but  sometimes  there  is  diarrhea. 

The  vomit  at  first  is  composed  of  undigested  food,  mucus,  and  a  little  bile, 
later  of  mucus  and  bile;  finally  it  becomes  bloody,  bright,  or  of  coffee-ground  con- 
sistence. In  one  of  the  writer's  cases  the  odor  was  almost  fecal.  The  blood  may 
come  from  the  mouth,  pharynx,  or  stomach,  and  carries  significance  only  if  from  the 
last.  The  urine  is  scanty,  high  colored,  contains  albumin,  casts,  sometimes  blood, 
bile,  acetone,  diacetic  acid,  indican,  and  even  sugar.  It  may  also  show  the  diazo- 
reaction.  The  urea  is  usually  high,  even  4  per  cent.,  but  Williams  believes  that  in 
such  cases  a  large  part  of  the  nitrogen  excretion  is  in  the  form  of  ammonia. 

During  the  second  stage  the  symptoms  become  aggravated,  and  everj'thing  is 
rejected  by  the  stomach;  the  patient  complains  of  intolerable  thirst,  is  extremely 
irritable  and  weak,  has  frequent  fainting  spells,  and  loses  weight  rapidly — in  severe 
cases,  as  much  as  a  pound  a  day. 

Examination  shows  the  skin  pale,  waxy,  sometimes  icteric,  non-resilient, 
shrunken,  the  patient  emaciated  (only  in  the  chronic  cases;  the  toxemic  cases  may 
die  before  emaciation  is  pronounced).  The  heart  and  lungs  usually  are  normal, 
the  pulse-beat  is  rapid, — 100  to  140,  weak,  "the  pulse  of  empty  arteries," — the 
abdomen  is  scaphoid;  one  can  trace  the  aorta  from  the  epigastrium  to  beyond  its 
bifurcation;  great  tenderness  is  elicited  over  the  cardia  and  sometimes  over  the 
liver.  The  irritating  vomit  has  eroded  the  lips  and  lower  face;  the  gums  are  red- 
dened and  covered  with  sordes;  the  tongue  is  red,  dry,  bro^vn  in  the  middle,  and 
cracked,  sometimes  to  bleeding;  the  pharynx  is  dry,  red,  sometimes  infiltrated 
\Aith  minute  hemorrhages;  the  breath  is  fetid,  and  may  have  a  penetrating  or  a 
soft,  fruity  odor.  Fever  of  a  low  grade,  but  continuous,  is  now  determinable, 
and  symptoms  referable  to  the  nervous  system  usher  in  the  third  stage.  In  some 
cases  the  temperature  remains  subnormal  until  just  before  death,  when  there  is 
an  agonal  rise.  Dehydration  of  the  blood — thickening — is  shown  by  the  hyper- 
globulism,  both  reds  and  whites,  and,  when  intense,  may  indicate  the  time  for 
terminating  the  pregnancy  (Dcvraigne). 

Third  Stage. — ^Mental  aberration,  delirium,  headache,  somnolence,  stupor, 
and  coma  occur  invariably.  The  vomiting  usually  ceases,  leading  the  attendants 
to  raise  false  hopes,  but  the  pulse  increases  in  frequency,  the  g(>neral  prostration 
rapidly  augments,  and  the  patient  dies  under  the  clinical  j)icture  of  uncontrollable 
vomiting  and  acute  starvation. 

The  length  of  the  three  stages  varies  very  much — the  first  is  long;  the  second, 
longer;   the  third  is  usually  short,  the  patient  rapidly  going  down,  and  herein  lies 


THE    TOXEMIAS    OF    PREGNANCY  345 

a  warning — not  to  let  tlic  disea-so  progress  to  the  third  stage,  l>ecause  then  even 
tlieraix-utic  abortion  cannot  stay  it;  on  the  contrary,  tlje  interference  may  ha.sten 
the  end.  The  disease  lasts  from  four  to  twelve  weeks,  usually  six  weeks,  hut  it 
may  be  acutelj'  fatal  in  ten  to  fourteen  days.  The  latter  cases  are  of  the 
toxemic  variety. 

During  all  this  disturbance,  local  and  general,  the  fetus  is  usually  alive,  an<l 
if  delivered  at  term,  may  be  large  and  fat.  If  the  vomiting  is  to.xemic,  the  fetus 
is  more  likely  to  suffer,  and  abortion  is  more  apt  to  occur.  The  vomiting  often 
cea.ses  on  the  death  of  the  fetus. 

Causation.- — Curiously,  more  cases  of  this  affection  are  reported  from  the 
United  States  and  France  than  from  Germany  and  England.  Carl  Braun,  in  an 
experience  of  over  150,000  obstetric  cases,  never  observed  one  of  hyperemesis 
that  was  fatal,  but  McClintock  was  able,  with  a  very  moderate  amount  of  search, 
to  collect  50  fatal  cases.  It  is  more  frecjuent  an<l  fatal  in  multipara'  than  in  primi- 
parse.  In  the  author's  19  cases,  12  were  nuiltipara',  and  of  Kcjsenthal's  100  ca.H-s. 
only  33  were  primiparie.  In  discussing  the  cause  of  hypereme.sis,  one  mu.st  not 
lose  sight  of  the  generally  increa.sed  nervous  excitability  of  pregnancy,  which  would 
tend  to  exaggerate  the  action  of  any  irritant  locatetl  at  any  part  of  the  Ixjdy. 
Uncontrollable  vomiting  is  more  common  in  neurotic,  neurasthenic.  an<l  hyst<'ric 
women,  but  it  is  particularly'  likely  to  develop  if  there  is  some  irritant  which  may 
act  on  the  stomach  via  the  nervous  system  or  blood.  A  study  of  my  ca.ses  of  hjper- 
emesis  and  of  milder  gastric  disturbances  shows  four  more  or  less  distinct  cla.'^ses: 
(1)  Those  in  which  the  vomiting  is  a  reflex  from  the  genitalia;  (2)  when  it  is  due 
to  some  disease  of  the  stomach,  some  al)dominal  disorder,  or  abnormal  condition 
of  the  blood;  (3)  where  the  nervous  system  is  at  fault;  (4)  where  the  general 
metabolism  is  disturbed,  the  clinical  picture  being  that  of  a  toxemia. 

1.  The  reflex  theory  of  hyperemesis  explains  many  cases,  and  appropriate 
treatment  often  is  curative.  Owing  to  the  close  nervous  connections  between  the 
genitalia  and  stomach  by  way  of  the  s^Tupathetic  and  vagus,  reflexes  through  this 
arc  are  easy,  as  many  common  examples  show.  Examples  of  peripheral  irritants 
capable  of  causing  the  vomiting  are  excessive  distention  of  the  uterus  (Bretonneau), 
the  ovum  growing  more  rajMdly  than  the  organ  can  bear,  as  in  metritis,  i>oly- 
hydranmion,  hydatid  mole,  twins,  displacement  of  the  uterus  ((Jrailly-Hewitt ), 
acute  anteversions  and  retroversions  and  flexions,  the  nerves  being  pinched  or 
stretched;  under  this  heading  may  be  placed  inflammations  of  the  uterus,  metritis, 
endometritis  (Veit),  tumors  of  the  uterus.  disea.ses  of  the  adne.xa,  pelvic  connective 
tissue,  and  peritoneum;  chronic  cervicitis,  with  or  without  erosions  (Bennett). 
The  plausibility  of  this  cause  is  shown  by  the  good  effect  of  treatment,  since  often 
when  the  pathogeny  is  corrected  the  vomiting  disappears.  Without  doubt  a 
special  predisposition  on  the  part  of  the  gravida  nmst  be  assumed  to  explain  the 
excessive  gastric  reactio!i  to  the  irritant,  because  such  diseases  of  the  genitalia 
often  exist  in  marked  degree  without  causing  vomiting. 

2.  Where  no  lesion  of  the  genitalia  is  discoverable,  i)Ut  other  di.^ea.^',  usually 
attended  by  vomiting,  is  present,  pregnancy  added  to  the  condition  may  make  the 
vomiting  pernicious.  Such  diseases  are  gastric  ulcer,  carcinoma,  chronic  gastritis, 
enteritis,  hehninthiasis.  large  fecal  concretions,  enteroptosis.  tulnTcular  peritonitis, 
gall-stones,  in  fact,  many  intra-abdominal  disorders.  Xasal  disease,  hyjiertroiihied 
turbinates,  .septal  spurs,  apical  and  laryngeal  tuberculosis,  anemia,  chlorosis,  all 
these  have  been  invoked,  and  in  occasional  instances  proved  cau.><ative.  If  not 
actually  causative,  they  may  act  as  predisposition.  Uremia  from  kidney  disea.«<e 
may  cause  vomiting.  l)ut  usually  in  the  last  months  of  i>n'gnancy. 

3.  The  nervous  system  is  frequently  at  fault,  either  with  demon.stral)le  disea.^, 
as  l)rain  softening,  locomotor  ataxia,  tubercle  or  other  tumors,  meningitis,  jxily- 
neuritis, — but  this  may  be  an  efi"ect  of  toxemia, — or  as  the  result  of  functional 


346      THE  PATHOLOGY  OF  PREGNANCY,  LABOR,  AND  THE  PUERPERIUM 

disturbances.  Hypereniesis  is  not  rare  in  hysterics,  but  in  all  probal)ility  most 
cases  may  be  explained  as  a  neurosis,  a  view  prominently  placed  by  Kaltenbach. 
Ahlfeld  and  Oliver  explain  the  vomiting  as  a  cerebral  circulatory  disturbance 
similar  to  sea-sickness.  Much  may  be  said  in  favor  of  Kaltcnbach's  contention,  e.  g., 
the  freciuent  occurrence  of  the  disease  in  neurotic  women,  the  good  effects  of  sug- 
gestive treatment,  and  it  is  more  than  plausible  that  a  neurotic  element  is  the  basal 
cause  of  the  vomiting  in  all  the  conditions  previously  mentioned  under  this  heading. 
Treatment  of  a  displaced  uterus  or  of  a  diseased  cervix,  for  example,  simply  re- 
lieves the  patient  of  the  periijheral  irritant,  l)ut  the  vomiting  ceases  because  the 
mobile  nervous  system  comes  again  into  equilibrium.  In  the  al^sence  of  actual 
local  disease,  pure  suggestion  may  cure  vomiting  in  these  neurotic  cases,  examples  of 
which  are  the  ice-bag  of  Chapman,  a  blister  applied  to  the  spine,  absolute  seclusion 
in  a  dark  room,  electricity,  some  drugs.  A  neurotic  constitution  is  usually  inherited 
from  parents  similarly  afflicted,  or  such  as  are  alcoholic,  insane,  or  debilitated. 
Unusual  stress  of  life  may  develop  it.  If  a  woman  dies  from  neurotic  vomiting, 
the  course  of  the  disease  is  very  chronic,  and  the  clinical  picture  and  pathologic 
findings  are  those  of  starvation. 

4.  Toxemia  best  explains  a  large  number  of  cases  of  hjq^eremesis,  and  the 
clinical  picture  as  well  as  the  pathogeny  seems  to  show  that  there  is  a  distinct  disease 
entity.  Dirmoser  believed  that  an  intestinal  auto-intoxication  causes  the  vomiting, 
a  view  which  is  supported  by  some  cases  in  practice.  That  the  liver  has  to  do  with 
this  disease  has  long  ])een  knoA\ai,  but  the  changes  of  this  organ  have  only  recently 
been  studied.  These  changes  in  the  liver  are  probably  due  to  the  basal  cause  of 
the  toxemia,  the  disturbed  metabolism.  No  one  has  suggested  that  they  may  be 
due  to  an  infection.  Charpentier  relates  a  case  where  the  excessive  vomiting  ceased 
on  the  opening  of  a  peri-urethral  abscess,  and  Goldspohn  one  where  the  removal 
of  a  fetid  placenta  from  the  uterus  effected  a  cure. 

A  neurotic  constitution  may  cause  toxemia. 

Toxins  derived  from  the  solution  of  syncytium,  syncytiotoxin,  are  believed  by 
Veit  and  others  to  cause  hyperemesis,  the  blood  not  furnishing  enough  antitoxin 
to  neutralize  them.  Recently  injections  of  the  serum  of  healthy  gravidas  have 
been  used  as  a  curative  measure — i.  e.,  to  supply  the  deficient  antibodies  to  the 
patient's  blood  (Mayer,  1911).  The  thyroid  gland,  the  adrenals,  defective  corpus 
luteum,  have  all  been  proposed  as  causes  of  the  disturbed  metabolism  (Fieux) . 

Toxemic  vomiting  cases  pursue  a  more  rapid  course,  without  much  emaciation, 
and  death  results  not  from  starvation,  but  from  the  profound  alterations  of  the 
general  metabolism. 

Pathologic  Anatomy. — At  autopsy  on  women  dead  of  hj-peremesis  gravidarum 
the  most  marked  changes  are  found  in  the  liver  and  kidneys.  The  liver  may  be 
slightly  enlarged  in  the  acute  stages,  but  after  the  degeneration  has  progressed 
somewhat,  it  is  smaller.  There  may  be  a  diffuse  hemorrhagic  hepatitis,  with  all 
the  findings  of  acute  yellow  atrophy.  There  may  be  fatty  degeneration  of  only  the 
cells  around  the  central  lobular  veins,  or  extensive  areas  of  necrosis  (Fig.  336). 
Thromboses  may  occur  in  branches  of  the  portal  vein.  Bile  stasis  is  the  rule. 
Hofbauer  says  the  glycerin  is  limited  to  the  periphery  of  the  lobule.  Pinard  claims 
that  slight  changes  of  this  kind  arc  constant  in  pregnane}^,  and  we  should  speak  of 
the  liver  of  pregnancy  as  well  as  of  the  kidney  of  pregnancy. 

The  kidney  suffers  all  the  changes  from  those  of  the  so-called  kidney  of  preg- 
nancy to  an  acute  parenchymatous  nephritis.  Fig.  338  shows  a  marked  fatty 
degeneration  of  the  epithelium  of  the  secreting  tubules.  The  glomeruli  are,  if  at 
all,  but  little  affected.  Hemorrhages  are  often  found,  and  i)ossibly  the  degenera- 
tion may  never  be  fully  corrected. 

The  heart  undergoes  fatty  degeneration  in  the  bad  cases,  as  in  sepsis.  The 
nerves  also  are  quickly  attacked  by  the  circulating  toxins. 


THE    TOXEMIAS    OF    PREGNANCY  o47 

Diagnosis. — First  one  must  dccicU'  when  tiic  vomiting  becomes  serious  enough 
to  be  ciilleil  ])ernieious.  Wiiea  tlie  stomach  rejects  everytinng;  when  the  anorexia 
is  complete  and  the  general  health  is  paliiably  affected,  one  must  conclude  that  the 
so-called  physiologic  vomiting  has  passed  over  into  the  pathologic.  As  (lueniot 
has  shown,  the  diagnosis  is  not  so  simple  as  appears  at  first  glance.  It  consists — 
(a)  Of  the  diagnosis  of  j)regnancv,  which  is  not  so  easy  in  the  first  trimester,  when 
the  ca.ses  usually  present  themselves;  (b)  in  det<'rmining  the  cau.ses  of  vomiting, 
basal  and  adjuvant;  (c)  the  differentiation  of  vomiting  due  to,  or  rendere<i  jxt- 
nicious  l)y,  pregnancy,  from  vomiting  having  no  connection  with  an  existing  preg- 
nancy, such  as  would  occur  in  the  absence  of  pregnancy.  The  diagnosis  (jf  pn-g- 
nancy  is  made  by  the  usual  methods,  and,  owing  to  the  emaciation,  l)imanual 
examination  is  rendered  easier.  A  careful  study  of  the  genital  findings  will  oft<'n 
lead  to  the  discovery  of  a  malposition  of  the  uterus  or  other  pelvic  anomaly  which

may  be  the  adjuvant  cause  of  the  excessive  vomiting — that  is,  the  iieripheral 
irritant.  Stomach,  intestinal,  hepatic,  hemic,  nervous  tlisea.-<es  will  require  the 
careful  general  medical  investigation  which  should  be  a  part  of  the  treatment  of 
all  ca.ses.  An  underlying  neurosis  is  not  always  lightly  a.ssumed.  The  toxic 
forms  of  vomiting  may  not  invariably  l)e  diagnoseil  by  urinary  examination. 
Williams  believes  that  high  annnonia,  even  to  40  jht  cent.,  with  low  urea-nitrogen 
output  in  the  urine,  indicates  a  to.xic  form  of  hyjien^mesis.  but  his  results  have 
not  yet  been  confirmed.  Jaundice,  fever,  rapid  pro.stration,  \nth  cerebral  .symptoms. 
acidosis,  early  all)uminuria,  with  casts,  or  blood,  much  acetone  and  diacetic  acid, 
tenderness  over  the  liver,  l^loody  vomit,  iv)int  to  a  toxemia,  while  the  more  gradual 
development  of  starvation  symptoms  leads  one  to  suspect  a  reflex  or  neurotic  cause 
for  the  vomiting. 

That  the  diagnosis  is  not  simple  is  proved  by  the  mi.«<take  made  by  Trou.sseau, 


348      THE  PATHOLOGY  OF  PREGNANCY,  LABOR,  AND  THE  PUERPERIUM 

where,  after  induction  of  abortion  for  hypereniesis,  the  autopsy  showed  cancer  of 
the  stomach,  and  one  by  Caseaux,  where  a  woman  supposedly  dead  from  vomiting 
of  pregnancy  had  tubercular  peritonitis,  and  the  one  of  Beau,  where  a  tubercular 
meningitis  caused  the  death.  W.  E.  Morgan,  of  Chicago,  relates  the  case  of  a  girl 
who.  in  extremis  from  vomiting,  threw  up  a  ])all  of  cotton  which  she  had  swallowed 
for  the  purpose  of  inducing  abortion.     Prompt  recovery  ensued. 

If  the  premises  are  made  very  broad,  the  patient  submitted  to  a  thorough  and 
complete  physical  examination,  and  sufficient  time  spent  on  the  consideration 
of  the  findings,  a  good  working  diagnosis  can  usually  1)6  made. 

Prognosis. — (Jueniot  colhH'tecl  118  cases,  with  46  deaths.  Statistics  are  un- 
certain because  the  ideas  of  observers  as  to  what  constitutes  hj^jeremesis  differ.

Carl  Braun,  in  an  immense  experience,  never  saw  a  death  from  the  vomiting,  which 
is  a  remarkable  statement,  because  they  do  occur.  The  disease  lasts  ten  days  to 
three  months,  depending  on  the  variety.  Not  seldom,  either  because  of  some  at- 
tempt at  treatment  or  spontaneously,  the  i^atient  suddenly  ceases  to  vomit,  de- 
mands food  and  retains  it,  going  on  to  rapid  recovery — this,  too,  when  the  previous 
condition  was  such  as  to  excite  real  alarm.  More  oft(Mi  the  disease  subsides  slowly, 
or  may  not  be  fully  cured  until  after  delivery.  If  the  fetus  dies  or  abortion  occurs, 
recovery  usually  begins,  but  not  invarialjly,  and,  too,  such  an  occurrence  is  rare, 
the  course  of  the  gestation  being  seldom  affected  by  the  general  disturl)ance.  If 
therapeutic  abortion  is  delayed  too  long,  it  cannot  prevent  death,  rather  may 
precipitate  the   impending  fatal  exhaustion.     The  toxemic  hyperemesis   is  less

350      THE  PATHOLOGY  OF  PREGNANCY,  LABOR,  AND  THE  PUERPERIUM 

combined  with  scale  ])epsin,  of  each  5  grains  thrice  daily  after  eating,  and  sug- 
gestive therapeutics  usually  suffice  to  make  the  gravida  comfortable.  Cognizance 
may  be  taken  of  the  ca]:)ricious  appetites  of  pregnant  women,  and  the  bizarre 
"longings"  may  be  satisfied  when  the  desired  food  is  digestible.  Dewees  roused 
the  patient  early,  gave  hot  coffee  and  crackers,  and  then  had  her  lie  in  bed  an  hour 
or  so,  a  plan  that  is  often  successful.  Coitus  is  to  be  forbidden,  the  wife  being  best 
given  a  separate  room.  The  knee-chest  position  for  ten  minutes  three  times  a 
day,  allowing  air  to  enter  the  vagina,  is  often  helpful.  Dyspepsia  or  symptoms  of 
gastric  disease  are  to  be  treated  on  general  medical  lines,  and  it  is  wise  to  search  for 
and  correct  all  abdominal  conditions  found  to  be  causative  of  hyperemesis. 

As  soon  as  a  given  case  shows  itself  to  be  obstinate  and  threatening,  the  woman 
should  be  put  to  bed,  isolated  as  far  as  possible,  and  a  thoroughly  competent  imrse 
put  in  attendance.  It  may  be  best  to  remove  the  patient  to  a  hospital.  The 
room  should  be  darkened  (ocular  disturbance  sometimes  causes  vomiting),  and  the 
horizontal  position  consequentially  insisted  upon,  even  while  taking  food.  In  one 
chronic  case  much  relief  was  obtained  by  the  patient  living  on  an  open  porch.  The 
bowels  must  lie  emptied  thorough!}'. 

Dietary. — Milk  and  lime-water  or  seltzer,  equal  parts,  ice  cold;  kumiss  or  matzoon;  a  strong 
beef  or  chicken  broth  ser^-ed  in  a  cup  with  salted  wafers;  cold  custard;  rice  and  milk  with  cinna- 
mon; a  sliver  of  white  meat  of  chicken  with  buttered  toast ;  a  strong  oyster  broth;  strained  oyster- 
stew;  toast  and  hot  milk  with  sugar;  ice-cream  and  ices;  soda-fountain  drinks;  cream  soups  with 
wafers.  If  the  stomach  rejects  these,  liquid  diet  is  ordered;  milk,  milk  and  seltzer,  peptonized 
milk  flavored  with  cinnamon  or  nutmeg,  light  broths,  albumin-water,  rice-water,  barlej'-water, 
beef-juice.  Occasionally  food  introduced  with  a  stomach-tube  will  be  retained  when  that  swal- 
lowed is  rejected.     If  the  vomiting  is  toxemic,  the  patient  is  put  on  a  milk  and  water  diet  at  once. 

Should  the  stomach  prove  absolutely  refractory,  rectal  feeding  is  instituted — 
nothing  is  allowed  by  mouth.  Salt  solution  ])y  the  drop  method  containing  dex- 
trose, peptones,  peptonized  milk  and  eggs,  digested  beef,  and  emulsified  fats  may 
be  given.  Underhill  emphasizes  the  need  of  carbohydrates  in  the  economy  during 
h>T)eremesis,  claiming  that  proteids  are  not  so  necessary.  It  has  been  stated  that 
the  lack  of  carbohydrates  causes  the  marked  acetonuria. 

Suggestion  forms  a  large  part  of  the  treatment  of  cases  of  pernicious  vomiting, 
and  without  doubt  many  of  the  measures  here  advocated  depend  on  it  for  their 
success.  The  phj^sician  should  determine  if  the  woman  is  suffering  from  a  neurosis, 
and  then  institute  a  course  of  treatment  with  a  view  to  impressing  her  with  his 
power  to  cure  her.     How  this  is  to  ])e  done  depends  on  individual  circumstances. 

Medical. — There  is  no  specific  for  this  disease,  as  the  host  of  remedies  used 
with  apparent  success  and  disheartening  failure  testifies. 

1.  Local  Anesthetics. — Cocain  hydrochlorid,  %  grain  in  1  ounce  of  water  (has  little  in- 
fluence on  the  bad  nausea  and  vomiting,  but  may  help  to  retain  some  food  for  a  while) ;  menthol, 
3^  to  H  grain  in  water;  volatile  oils — peppermint,  wintergreen — in  small  doses.  Cracked  ice 
swallowed  whole  may  relieve  thirst. 

2.  Mechanical  Drugs. — Bismuth,  cerium  oxalate,  soda-mint  tablets,  milk  of  magnesia,  etc., 
may  be  tried.  Digestive  ferments  do  not  act  so  well  as  in  the  non-pn^gnant  state,  but  pepsin  and 
ingluvin  may  be  tried.  When  chronic  gastritic  or  atonic  dj-speptic  symptoms  appear,  tincture 
of  nux  vomica  and  hydrochloric  acid,  especially  if  an  alcoholic  basis  is  suspected.  Usually,  as 
the  disease  gets  worse,  drugs  are  more  harmful  than  good. 

3.  Depressomotors. — Sodium  bromid  may  be  given  in  30-grain  doses  by  rectum,  and  mor- 
ph\n,}4  grain  hypodermically,  for  temporary  relief.  The  effect  is  apparent,  but  the  drugs  may 
later  increase  the  nausea.  A  hypodermic  of  morphin  may  be  given  just  after  the  feeding  and  it  may 
serve  to  retain  the  meal.  In  some  cases  of  centric  vomiting  alcohol,  in  the  form  of  dry  champagne 
or  brandy,  served  in  cracked  ice,  has  a  good  effect.     If  it  is  retained,  we  may  go  on  witli  other  food. 

4.  External  Remedies. — Ether  spray  and  pressure  on  the  stomach;  warm  flannel  band  or  ad- 
hesive straps  around  the  stomach,  tightly;  fly-blister  to  epigastrium;  Chapman's  ice-bag  (a  long 
cyhndric  ice-bag)  to  the  spine,  or  a  blister  to  the  fifth  or  sixth  cervical  spine.  Electricity  is  of 
little  value,  but  may  be  used  as  a  suggestion.  The  galvanic  current  may  be  employed  or  electric 
radiation  of  the  epigastrium. 

Kaltenbach  has  warmly  recommended  washing  out  the  stomach.  In  certain  hysteric  cases 
it  does  great  good,  and  in  gastroptosis  and  gastritis  may  also  be  useful.  It  is  not  to  be  used 
if  the  patient  is  too  weak,  as  it  is  depressing,  or  if  a  gastric  ulcer  is  suspected. 


THE   TOXEMIAS    OF    PREGNANCY  351 

5.  Disease  of  the  niusopharyiix  is  to  be  trcatcHl.  Temporary  relief  is  occasionally  obtained 
by  spraying  the  nares  with  4  per  cent,  solution  of  cocain. 

(■).  SfiU  solution,  0.7  jM-r  cent.,  injected  subcutaneously,  is  a  valuable  addition  to  our  nie:ins 
for  meeting  the  lo.ss  of  \)i>dy  fluids  from  the  constant  vomiting.  A  (juart  may  be  injected  every 
day  or  a  i)int  .several  times  a  day. 

The  extremities  may  be  wrajjped  in  wet  towels,  and  immctions  of  oil  or  lard  ased,  some  of 
these  being  absorbed.     Bi'd-.sores  must  be  assiduously  prevented. 

The  latest  remedies  for  hj'peremesis  are  suprarenal  extraet,  proposed  hy  Re- 
baudi  in  1909,  and  the  serum  of"  healthy  i)re{<nant  women,  recommended  hy  Fretmd 
in  190!)  anil  hy  Mayer  in  1911.  I  have  used  adrenalin  many  times,  with  success  in 
half  of  the  ca.ses.  Ten  drops  of  the  1 :  1000  .solution  are  ii^iven  three  tinu-s  a  day  hy 
mouth,  or  three  drops  hypodermically.  I  have  not  yet  ased  the  serum.  <jf  which 
20  c.c.  are  injected.     Pituitrin  has  not  yet  been  tried. 

(/i/nccologic  Trcdtmcnt. — Examine  carefullj'  with  the  aid  of  a  speculum,  and 
anythinf^  abnormal  must  be  remedied  if  po.ssible. 

An  anteverted  or  a  retroverted  utertis  is  replaced — in  the  knee-chest  jjosition, 
if  necessary — and  a  pessary  inserted.  In  one  of  the  writer's  cases,  the  wife  of  a 
colicajiue,  an  acutely  anteverted  uterus  was  rai.^^ed  with  a  balloon  pessary,  with 
immediate  ces.sation  of  pronounced  nausea  and  vomiting.  Owin^  to  a  ])in-hoIe 
defect  in  the  bag,  the  air  .slowly  escaped  and  the  symi)toms  firadually  returned, 
to  di.sappear  permanently  when  a  perfect  instrument  was  substituted,  thus  jiroving 
that  the  effect  was  not  due  to  suggestion. 

An  erosi(m  of  tiie  cervix  is  treated  with  10  per  cent,  solution  of  .silver  nitrate — 
indeed,  the  method  should  be  empl<)3'ed  on  empiric  grounds  even  if  the  cervix 
exhibits  no  alteration.  After  irrigation  of  the  vagina  with  sterile  water  a  small 
Fergu.son  speculum  is  introduced  and  the  cervix  engaged  in  its  end.  The  silver 
solution  is  poured  in  and  allowed  to  remain  five  to  ten  minutes  until  the  ti.*!sues  are 
wiiit(Mied,  then  wa.-^hed  out  with  1  per  cent,  salt  solution.  After  two  days  the  treat- 
ment may  l)e  repeated.  Its  rationale  is  not  understood,  but  it  is  oft<'n  efficacious, 
and  Carl  Braun  used  it  as  a  routine  practice.  Bennett,  the  inventor,  used  carbolic 
acitl  and  iodin.  M.  O.  Jones,  of  Chicago,  recommended  the  silver,  but  J.  Marion 
Sims  drew  general  attention  to  the  remedy.  In  one  ca.se  where  the  silver  aiijilica- 
tions  failed  the  author  employed  Bier's  suction  treatment  applied  to  the  cervix. 
The  woman  was  in  desperate  condition,  and  abortion  was  the  next  proceilure,  but 
recovery  ensued  and  the  jjregnancy  went  to  term.  How  much  the  local  treatment 
contributed  to  the  result  is  imcertain.  Copeman,  of  Norwich,  in  187.'i,  in  a  ca.'^e  of 
hyperemesis,  tried  to  induce  abortion  by  dilating  the  cervix  with  his  finger,  but 
failed;  his  patient,  however,  ceased  to  vomit.  Subsequently,  dilatation  of  the 
cervix  became  a  recognized  method  of  treatment,  to  be  employed  before  abortion 
was  induced,  as  a  next  to  the  last  re.sort.     The  author  has  never  u.-^ed  it. 

Ohstcfn'c. — Therai)eutic  abortion  will  cure  most  ca.ses  of  hyixTcmesis  if  done 
early  enough.  It  will  cure  all  ca.ses  of  neurotic  or  reflex  vomiting  unless  the  i)atient 
is  too  near  death  from  starvation  and  exhaustion  to  withstand  the  ojieration. 
Toxemic  vomiting,  being  an  expression  of  a  ])rofounil  systemic  alteration  of  the 
metal)olism,  does  not  resjiond  so  (luickly.  because  the  organs,  especially  the  liver, 
may  have  been  too  much  damaged  l)y  the  j^oisons  circulating  in  the  blood.  Wil- 
liams' advice,  therefore,  to  emi)ty  the  uterus  as  .soon  as  the  vomiting  is  pronounce.  1 
toxemic,  deserves  serious  consideration,  though  one  may  not  always  follow  it. 
In  the  first  i)lace,  a  ]X)sitive  diagnosis  of  toxemia  cannot  always  be  mad«'.  and. 
too,  many  cases  of  toxemic  vomiting  recover  under  the  usual  treatment. 

The  delicate  ])oint  to  determine  is  when  to  emptij  the  uterus,  and  the  general  ai>- 
pearance  of  the  patient  mu.st  decide  it.  Hofbauer  .says  that  if  glycosuria  results  after 
the  ingestion  of  2  ounces  of  levulose,  a  test  of  the  glycoh-tic  power  of  the  organ,  the 
time  is  at  hand,  becau.se  this  j^roves  that  theliverisalreadyattackedbytoxinsandhas 
begun  to  sutler.     Examination  of  the  blood,  showing  intense  concentration  (hyper- 


352      THE  PATHOLOGY  OF  PREGNANCY,  LABOR,  AND  THE  PUERPERIUM 

en'throcj'tosis  and  leukocj-tosis),  may  indicate  the  degree  of  starvation.  Pinard 
says  that  when  the  pulse  remains  above  100  one  should  not  delay  the  operation, 
and  many  accoucheurs  interfere  on  the  apjjearance  of  fever,  hematemesis,  jaundice, 
all)uniinuria,  incllituria,  acetonuria,  indicanuria,  the  diazo-reaction,  or  marked  loss 
of  weight.  Fieux  holds  that  polyneuritis  with  icterus  and  the  appearance  of  bile- 
pigment  in  the  urine  indicate  abortion.  Not  one  but  all  these  facts  must  be  con- 
sidered, together  with  one's  clinical  experience.  The  disease  is  so  treacherous  that 
it  is  better  to  interfere  earlier  rather  than  too  late,  because  often  many  remedies 
are  tried  in  succession,  using  up  much  time  and  then,  when  the  uterus  finally  has 
to  be  emptied,  the  patient  is  in  no  condition  to  stand  the  shock  of  operation.  Con- 
sultation must  alwaj's  be  had,  first,  to  verify  the  diagnosis  and  the  necessity  of  per- 
forming abortion;  second,  to  protect  the  attendant  from  the  imputation  of  criminal 
operation,  and,  third,  to  share  responsibility.  All  appearance  of  secrecy  is  to  be 
avoided,  the  operation  being  performed  in  a  hospital,  if  possible.  In  early  cases  the 
best  way  is  to  dilate  and  curet  the  uterus  in  one  sitting.  Later  in  pregnancy  it  maj-  be 
better  to  dilate  the  uterus,  insert  gauze,  and  complete  the  operation  the  next  day. 
When  great  haste  is  demanded,  anterior  vaginal  hysterotomy  is  the  operation  of  choice. 
Freund,  in  three  cases,  with  much  ado  pretended  to  do  abortion  and  thus  cured  the 
vomiting.  One  could  try  this  drastic  mode  of  suggestive  therapeutics  when  the 
hyperemesis  is  due  to  a  neurosis. 

Hyperemesis  is  sometimes  feigned  so  as  to  mislead  the  accoucheur  into  per- 
forming an  abortion.  The  patient  will  exaggerate  her  symptoms  and  falsify 
statements.     In  all  cases  the  objective  signs  only  should  be  relied  upon. 

Literature  on  hyperemesis  gravidarum  is  to  be  found  in  article  by  Ingraham, 
Jour.  Amer.  Med.  Assoc,  1912,  page  28. 


PTYALISM 

Salivation  is  a  rare  complication  of  pregnancy  It  is  related  to  hyperemesis 
in  that  it  is  probably  caused  reflexly.  Hippocrates  noted  it  in  pregnancy.  It  is 
to  be  cUstinguished  from  the  "cotton  spitting"  described  by  Dewees  as  one  of  the 
signs  of  pregnanc3^ 

Salivation  combined  with  nausea  and  vomiting  frequently'  occurs,  but  may 
occur  alone.  It  usually  begins  in  the  second  month,  and  ceases  about  the  fifth 
or  at  quickening,  presenting  the  same  variations  as  the  vomiting.  It  almost  al- 
ways ceases  with  parturition,  but  has  continued  for  a  few  weeks  thereafter.  It 
usually  occurs  but  once,  but  may  appear  in  successive  pregnancies,  and  may  be 
absent  in  one  and  recur  in  the  next.  The  flow  varies  in  amount,  excessive  quantities 
being  reported — over  two  quarts  a  day.  It  usually  lessens  during  the  night,  but 
may  continue  unabated.  The  saliva  is  very  watery,  tasteless,  odorless,  limpid, 
not  acid;   it  has  little  ptyahn.     The  patient  cannot  swallow  it :   it  nauseates. 

The  drain  of  this  large  amount  of  fluid,  the  absence  of  digestive  power,  and  the 
loss  of  appetite  not  seldom  compromise  the  nutrition  of  the  patient,  and  a  condi- 
tion of  exhaustion  resembling  that  produced  by  incoercible  vomiting  has  proved 
an  indication  for  terminating  the  pregnancy  in  these  cases  (rare).  There  are  few 
changes  in  the  mouth  or  gums.  The  salivary  glands  may  be  a  little  swollen  and 
tender;  the  tongue  is  coated,  with  red  edges;  and  sometimes  a  gastric  catarrh 
exists.  The  patients  feel  miserable,  are  always  thirsty,  have  difficulty  in  talking, 
and  the  chin  may  be  excoriated. 

Ptyalism  has  the  same  causation  as  hyperemesis,  and  occurs  most  often  in 
neurotic  women.     It  may  be  a  familial  characteristic. 

The  diagnosis  is  easy,  since  mercurial  salivation  is  attended  by  fetor  and 
stomatitis.  Montgomery  says  that  ptyalism  may  be  a  symptom  of  hysteria  and 
of  cancer  of  the  uterus. 


THE    TOXKMIAS    OF    I'KEGNANCY  353 

The  trcatinciit  is  i)ursuttl  aluii;;  tlic  same  lines  as  in  liyporomosis.  Of  the  many 
drills  usotl,  sodium  bromid  is  the  Ix'st — 20  grains  thrice  daily.  Pilocarpin  is  less 
efficient,  and  atropin  is  useless  and  dangerous. 


GINGIVITIS 

The  slight  tumefaction  and  hyperemia  of  the  gums  so  often  ol)served  in  preg- 
nancy (■)()  to  00  per  cent.)  may  i)e  aggravated  to  a  severe  affection.  Spongines.s 
of  the  gums,  hemorrhage  into  them  and  from  them,  even  lo(jsening  and  dropping  of 
the  teeth,  occur.  There  is  no  fetor,  no  salivation,  and  then-  is  usuall\-  little  pain 
in  the  parts,  though  ma.sticati(m  is  difficult.     There  is  no  periodontitis. 

Redness  of  the  gingival  margins  and  hypertrophy  are  visible,  and  soiiK-times 
polyjioid  excrescences  of  varying  size,  which  are  subject  to  ulcerati(jn,  apjwar  be- 
tween the  teeth.     The  region  of  the  molars  is  less  affe<-ted. 

( lingivitis  affects  jH-imipara'  and  multipara*  alike,  but  is  more  conmion  in  those 
who  neglect  the  teeth  and  person  antl  in  women  of  poor  health.  It  b<'gins  about 
the  fourth  month,  tlisappears  after  delivery,  but  may  even  apiwar  in  and  \h'  aggra- 
vate(l  by  lactation.  It  may  recur  in  each  pregnancy.  Its  causati(jn  is  obscure. 
Perhai)s  the  altered  buccal  secreti(jns  i)lay  a  role,  or  the  altered  metabolism  of 
pregnancy  (to.xemia?).  The  treatment  is  hygienic;  antiseptic  mout h-wii.shes, 
as  tincture  of  myrrh  in  water,  jjotassium  chlorate,  1  ounce  in  1  pint  of  wat<'r,  milk  of 
magnesia,  cleansing  the  gums  with  a  soft  cloth,  rubbing  precipitated  chalk  into  the 
crevices,  and  iron  and  calcium  tonics,  combined  with  (jutdo(^r  living.  Hemorrhage 
from  the  gums  is  treated  by  a  compress  of  gelatin  or  of  adrenalin,  or  cauterization. 
Polypoid  excrescences  may  be  removed  a  few  weeks  postj)artum  if  they  d(j  not 
shrink  up. 

Toothaclu'  is  a  not  infrecjuent  occurrence  in  ])regnancy,  and  it  is  especially 
troublesome  in  women  subject  to  neuralgia.  Carious  teeth,  also  connnon,  should 
be  cared  for  during  gestation;  even  extraction  untler  gas  should,  if  indicated,  be 
made,  but  exhausting  gold  fillings  had  better  be  postponed,  temporary  cement  or 
inlays  i)eing  insert(>d.  'J'lie  gravida  should  be  given  a  tonic  of  lime  and  h\-]x>- 
phosphiles. 

ECLAMPSIA  AND  ALLIED  CONDITIONS 

One  of  the  most  dangerous  complications  that  may  befall  the  pregnant  woman 
is  convulsions  attended  by  coma.  Naturally,  a  gravida  may  suffer  from  the 
convulsive  seizures  to  which  any  woman  is  liable,  such  as  epil<'j)sy.  hysteria, 
meningitis,  etc.,  but  there  is  a  symptom-complex  i)resented  by  jiregnant  women, 
of  which  convulsions  are  the  most  prominent  manifestation,  to  which  the  t<'nn 
"eclampsia  parturientium"  is  ai)i)lied.  There  are  several  varieties  of  symptom- 
groups  or  syndromes,  some  i)ointing  to  the  liver  as  the  main  seat  of  the  trouble, 
others  pointing  to  the  kidney^,  others  to  both.  Again,  the  convulsions  may  l)e 
absent,  the  condition  being  one  of  failure  of  one  or  the  other  organ.  Under  this 
heading  would  come  the  kidney  of  pregnancy  and  acute  yellow  atrophy  of  the  liver, 
because  the  first  often  l(>ads  to  convulsions,  and  the  other  is  not  seldom  a  terminal 
condition  of  eclampsia. 

It  is  iinj)()ssible  to  classify  thesi>  diseases  l)ecause  the  causes  are  unknown. 
They  all  could  b(>  grouped  under  one  head,  toxicoses  or  toxemia,  if  it  were  known 
that  an  intoxication  of  the  blood  really  lies  at  the  ba.se,  but  this  theory,  while  gen- 
erally believed,  and  indeed  viTy  l>lausibl(^  is  not  po.sitively  proved.  One  would 
then  speak  of  a  nephritic  to.xemia,  a  hepatic  toxemia,  cerebral  toxemia,  depending 
on  which  organ  is  most  affected  by  the  circulating  jjoi.son,  or  whose  symptoms 
dominated  the  clinical  picture  or  postmortem  findings.  At  present  we  group  all 
cases  of  convulsions  and  coma  occurring  in  i)regnant  wt)men,  not  due  to  extraneous 
23 


354      THE  PATHOLOGY  OF  PREGNANCY,  LABOR,  AND  THE  PUERPERIUM 

medical  causes,  as  hysteria,  epileps}',  tubercle  of  the  brain,  etc.,  under  the  term 
eclampsia.  Those  rare  cases  where  the  woman  has  all  the  symptoms  of  eclampsia 
without  con\iilsions  Ave  call  eclampsia  just  the  same.  The  kidney  of  pregnancy  is 
generally  held  to  be  due  to  a  preeclamptic  toxemia  of  very  mild  degree.  The  neph- 
ritis of  pregnancy  is  the  next  step  in  the  gradation  to  the  real  nejihritic  form  of 
eclampsia.  The  liver  is  always  involved  either  primarily  or  secondarily,  and  some 
cases  of  eclampsia  seem  to  be  due  entirely  to  hepatic  inefficiency,  the  renal  changes 
being  secondary,  and  such  cases  are  likely  to  terminate  under  the  clinical  picture 
of  acute  yellow  atroplu'  of  the  liver,  presenting  the  classic  autopsy  findings. 

History. — Hippocrates  mentions  con\njlsions  of  pregnant  women  and  knew  that  they  most 
often  occurred  in  women  who  had  headache  and  a  tendency  to  sleep  (coma).  The  word  eclampsia 
means  to  flash,  or  shine  out,  and  was  introduced  by  Boissier  de  Savages  in  1760  and  Gehler 
in  177G.     More  properly  it  should  be  eclactisma  (Kossman). 

Clinical  Course. — Prodromata. — The  eclamptic  attack  mayoccur  suddenly  with- 
out warning,  but  this  is  not  the  rule — almost  always  there  are  premonitory  symp- 
toms, so  that,  with  ordinary  care,  the  accoucheur  is  not  taken  unawares.  These 
symptoms  are  headache,  dizziness,  a  tendency  to  nervous  excitation  or  to  sleep, 
occasionally  slight  mental  unbalance,  tA\dtchings  in  the  muscles,  cramps  in  the  calves, 
nausea,  vomiting,  pain  in  the  epigastrium,  and  disturbances  of  the  special  senses — 
spots  before  the  eyes, — muscae  volitantes, — bright  lights,  sometimes  colored,  some- 
times described  as  spangles,  dimness  of  vision,  even  complete  l^lindness,  due  to  edema 
or  retinitis  and  sometimes  with  hemorrhages,  photophobia;  ringing  in  the  ears,  even 
deafness,  and  occasionally  anomalies  of  taste  and  smell.  Prodromata  are  present 
from  a  few  hours  to  several  weeks  before  the  actual  outbreak,  and  serve  to  draw 
attention  to  the  condition  of  the  patient. 

These  warnings  should  he  heeded  and  an  exhaustive  examination  of  the  patient 
made.  This  will  usually  show  edema  of  the  feet  and  eyelids,  or  more  or  less  marked 
general  anasarca,  with  pasty  skin,  a  coated  tongue,  fetid  breath,  tenderness  over 
the  pit  of  the  stomach  (the  site  of  the  pain)  and  over  the  liver,  high  pulse  tension 
with  accentuated  second  heart-sound,  intensely  exaggerated  reflexes,  diminished 
urine,  high  specific  gravity,  albumin  with  hyaline  and  granular  casts,  and  low  urea 
output.  Occasionally  the  urinar}-  findings  are  negative,  but  there  is  marked  edema, 
with  or  without  symptoms,  and  sometimes  edema  fails,  but  marked  subjective 
manifestations  are  present.  Rarely  one  observes  a  slight  subicterus.  These  symp- 
toms may  be  called  those  of  preeclamptic  toxemia,  the  eclampsisme  of  the  French, 
and  a  patient  presenting  them  may  be  said  to  be  threatened  with  convulsions. 

The  Attack. — Wherever  the  patient  may  be,  she  falls  to  the  ground  unconscious. 
The  pupils  dilate,  the  eyes  are  turned,  and  the  head  also,  to  one  side;  the  patient 
opens  her  mouth,  then  the  jaw  is  pulled  laterally,  and  there  may  be  a  cry  or  a  sigh. 
The  whole  body  becomes  rigid;  the  features  are  distorted;  the  arms  flexed;  hands 
clinched;  the  feet  inverted;  the  toes  flexed,  and  the  whole  person  drawn  to  one  side 
in  a  tonic  spasm.  This  condition  lasts  for  a  few  seconds,  then  the  jaws  open  and 
close  violently,  the  eyelids  also,  the  twitchings  beginning  in  the  face,  then  usually 
one  arm,  then  the  leg,  and  now  the  whole  body.  This  is  a  violent  clonic  con\Tjlsion, 
which  may  throw  the  patient  out  of  the  bed  against  any  object.  Severe  injuries  can 
result — even  fractures  of  the  skull  or  long  bones;  the  tongue  is  protruded;  the 
teeth  may  chop  it  up.  Foam,  often  tinged  with  blood,  comes  from  the  mouth. 
The  respiration  is  completely  stopped,  the  chest  being  rigitl.  The  pulse  is  high  and 
strong;  later  it  grows  weaker,  })ut  may  be  hard  to  feel  ])ecause  of  the  convulsion. 
In  rare  cases  the  pulse  is  weak  and  the  arterial  tension  low  from  the  start,  a  fact 
Avhich  is  explained  by  degenerative  changes  in  the  heart.  The  blood-shot  eyes 
protrude,  the  face  is  swollen,  the  cyanosis  is  extreme,  the  lips  are  purple — altogether 
the  picture  is  a  horrible  one.  Gradually  the  convulsive  movements  remit,  a  few 
twitches  or  jerks  take  place,  the  patient  lies  quiet,  the  heart  thumping  violently 


THE  TOXEMIAS  OF  PREGNAN'CY  355 

against  the  clu'st-wall.  For  a  few  secontls  the  woman  appears  to  be  dying,  but 
there  is  a  long  sigh,  and  stertorous  breathing  Ijeconies  estabUshed,  coma  super- 
vening. Soon  the  respirations  fjuiet  down.  In  the  favorable  c-a.>ies  tlie  patient 
wakes  up  after  a  short  time  bewildered,  .severely  sore  in  all  the  mu.*<eles.  After 
from  a  few  minutes  to  an  hour  another  fit  oceurs,  or  she  may  have  no  more.  With 
recurring  convulsions  the  intervals  become  shorter  and  the  patient  lies  in  deep 
coma  all  the  time.  Fever  now  begins;  the  pulse-rate  rises.  The  fits  may  occur 
every  five  minutes,  but  usually  the  time  is  twenty  minutes  to  one  hour,  and  they 
may  show  some  regularity  of  recurrence.  ('a.ses  are  on  reccjrd  of  SI  (recovery)  and 
even  104  convulsions  (Olshausen).  These  ca.ses  almost  invariably  die.  The  aver- 
age number  is  from  5  to  15  attacks.  The  convulsion  lasts  from  thirty  seconds  to 
two  minutes,  very  rarely  any  longer,  and  these  are  bad  ca.><es.  Between  the  attacks 
the  patient  may  be  quiet  or  restless,  and  sometimes  there  is  great  jactitation,  with 
wild  and  exiiaustive  delirium.  These  cases  usually  show  signs  of  severe  liver 
involvement. 

Pains  usually  begin  if  the  convulsions  are  at  all  severe,  and  labor  is  often  rapid, 
when  once  bej^un.  Aft<'r  lal)()r  the  ])r()gress  of  the  cases  is  generally  more  favorable, 
but  the  convulsions  may  reccjinmence  as  late  as  the  eighth  day.  ( )f  great  interest 
is  postpartum  eclami)sia.  Wlien  the  convulsions  begin  after  the  deliven,'  ofthe 
child,  or  a  long  time  after  the  death  of  the  fetus,  it  is  probal)le  that  the  poison  was 
retained  some  place  and  finally  was  freed  so  that  it  could  unite  with  the  brain-<-ells 
(Liepman). 

Marked  albuminuria  with  ca.sts  and  blood  are  the  rule  in  true  eclampsia;  occa- 
sionally there  is  anuria.  Cases  of  eclampsia  without  albuminuria  are  due  to  apo- 
plexy, epilepsy,  meningeal  disease,  or  reflex  irritation.  Examination  of  eclamptic 
women  often  shows  tenderness  over  the  liver,  kidneys,  and  stfjmach,  with  greatly 
exaggerated  reflexes,  marked  leukocytosis,  and  often  complete  amaurosis. 

If  the  woman  is  to  get  well,  the  convulsions  grow  less  frec|uent  and  less  severe, 
the  coma  lightens,  the  temperature  goes  down,  the  pulse  slows,  the  cyanosis  dis- 
appears, the  mind  begins  to  clear,  and  after  from  six  hours  to  three  days,  rarely 
as  long  as  a  week,  consciousness  returns.  A  recrudescence  of  the  fever  usually 
means  that  sepsis  is  starting.  Recollection  of  what  hai)iK'ned  from  the  beginning 
is  completely  lost,  and  the  puerpera  may  deny  her  child  when  it  is  presented  to  her. 
This  amnesia  may  extend  as  far  back  as  a  week  before  the  actual  attacks  l)egan, 
anrl  occasionally  there  is  weakness  of  mentality  for  several  months  after  tleliver>'. 
Puerperal  i)sychoses  are  not  unconnnon  as  a  secjuel  to  those  cases  having  had  many 
convulsions,  but  they  usually  offer  a  gootl  prognosis. 

In  rare  instances  the  convulsions  cease  without  interrupting  pregnancy,  and 
the  patient  may  deliver  a  living  cliild  at  t(Tm.  The  author  had  a  ca.<e  where  the 
patient  had  two  attacks  during  j^regnancy,  with  an  interval  «»f  three  weeks,  in  one 
of  which  attacks  the  convulsions  were  so  severe  that  the  jaw  was  dislocated,  and 
yet  a  living  child  was  liorn  at  term.  More  usually  the  attack  kills  the  fetus,  the 
symptoms  al)ate,  and  the  product  of  conception  is  exix'lled  in  due  course  of  time. 

If  the  woman  is  going  to  die,  the  attacks  usually  increase  in  fre<iuency  and 
force,  the  teini)erature  goes  up  to  103°  F..  sometimes  to  lOT^F..  or  it  sinks;  the  pulse 
incretuses,  becomes  weak  and  running.  Signs  of  edema  of  the  lungs  ai)jM'ar,  with 
rattling  and  pule  cyanosis,  even  between  tlu'  convulsions,  or  death  nuiy  take  place 
at  the  height  of  a  convulsion  from  apoplexy  or  heart  j^aralysis.  There  is  anuria 
or  hein()glol)inuria.  or  one  ol)tains  a  few  drams  of  thick,  brownish  urine  from  the 
bladder,  wliicii  solidifies  when  heated. 

Sometimes  the  woman  is  successfully  delivered,  but  the  pulse  does  not  impnne, 
the  coma  deepens,  and  edema  pulmonum  closes  the  scene.  Some  cases  are  bad 
from  the  start,  the  patient  dying  after  one  or  two  convulsions  in  a  few  hours.  Some- 
times there  are  no  lits,  the  jiatient  falling  at  once  into  coma,  and  even  coma  may 


3oG      THE  PATHOLOGY  OF  PREGNANCY,  LABOR,  AND  THE  PUERPERIUM 

fail,  the  patient  dying  of  exhaustion  in  collapse  (Schniid).  As  a  rule,  the  case  ends 
one  way  or  the  other  within  three  days. 

Rarely  the  course  of  the  disease  is  that  of  acute  yellow  atrophy  of  the  liver, 
with  jaundice,  petechia^,  diminished  liver  dulness,  the  urinary  findings,  delirium, 
jactitation,  coma,  exit  us. 

Other  Forms  of  Eclampsia. — Occasionally  after  a  severe  labor  or  during  the 
last  part  of  the  second  stage  the  parturient  will  have  a  single  convulsion  or  a  second 
milder  one,  without  or  with  very  slight  all)uminuria.  This  is  called  eckwipsia 
reflcdorica,  and  is  the  discharge  of  the  overwrought  nervous  system,  ])ut  in  all 
probability  there  is  a  toxemic  element  also. 

An  acute  collapse  after  labor,  simulating  internal  hemorrhage,  embolism,  or 
edema  of  the  brain,  and  attended  by  albuminuria,  is  of  the  same  nature  as  eclampsia, 
and  requires  careful  differcnitiation  from  the  other  conditions. 

Another  form  of  toxemia  occurs,  presenting  all  the  manifestations  of  eclampsia 
without  convulsions.  The  patient  sinks  at  once  into  coma,  which  is  almost  always 
fatal.     Marked  liver  autolysis  is  usually  found  at  autopsy. 

Nephritic  Eclampsia. — Women  with  chronic  nephritis  seldom  have  convulsions 
in  pregnancy  and  labor,  but  they  suffer  from  other  complications — anasarca,  uremia 
(usually  coma),  pulmonary  edema,  cardiac  paralysis,  retinitis  albuminurica, 
cerebral  hemorrhage,  then  with  convulsions,  premature  labor,  abruptio  placentae. 
Convulsions  do  occur  in  chronic  nephritics,  and  then  it  is  hard,  but  usually  possible, 
to  make  the  differential  diagnosis. 

Acute  nephritis  is  more  easily  developed  in  a  pregnant  woman  because  the  kid- 
neys are  carrj-ing  an  increased  burden,  and,  too,  are  often  diseased  through  the 
pregnancy  changes  (the  kidney  of  pregnancy,  Leyden),  and  when  it  does  occur, 
convulsions  almost  always  result.  An  apparently  healthy  gravida,  suddenly, 
after  exposure  to  cold,  after  a  flagrant  error  of  diet  (a  Christmas  dinner,  for  example), 
or  follo\\dng  an  angina,  develops  an  acute  nephritis  with  convulsions.  These  cases 
are  the  ones  which  occur  without  much  warning,  and  may  surprise  the  most  pains- 
taking accoucheur,  and  clinically  they  cannot  be  differentiated  from  true  eclampsia. 

Causation. — Eclampsia  occurs  once  in  about  600  pregnancies,  but  this  varies 
in  different  statistics  and  in  different  localities.  The  cause  of  this  variation  is 
unknown.  Primiparse  are  oftener  (3  to  1)  affected  than  multiparae,  but  in  the  latter 
the  prognosis  is  usually  worse.  It  generally  appears  in  the  last  three  months  of 
pregnancy,  but  may  occur  as  early  as  the  tenth  week  (author's  case).  Fatal  cases 
are  reported  in  the  third,  fourth,  and  fifth  months.  In  about  20  per  cent,  of  the 
cases  the  convulsions  begin  during  pregnancy;  in  60  per  cent,  during  labor,  and  in 
20  per  cent,  after  delivery.  Schroder  had  62,  190,  and  64  cases  respectively.  Pre- 
disposing causes  are  primiparity,  especially  in  advanced  years,  excessive  nervous 
irritability,  prc^vious  disease  of  the  kidneys  or  liver  (scarlatina  or  other  infectious 
disease),  heredity  (Elliott  reports  a  case  where  a  mother  and  four  daughters  died  of 
eclampsia),  twin  pregnancy,  contracted  pelvis,  infantilism. 

In  spite  of  the  enormous  amount  of  study  that  has  been  put  upon  it,  the  real 
cause  of  the  disease  is  unknown.  The  theory  that  has  most  plausibility  is  that  of  a 
toxemia — some  poison  circulating  in  the  blood  which  produces  necrosis  of  the  liver, 
and,  directly  or  indirectly,  degenerative  changes  of  the  Iddneys  and  also  convulsions, 
by  direct  toxic  action  on  the  anterior  cerebral  cortex. 

Where  do  these  toxins  originate?  Many  theories  have  boon  advanced.  HallxTtsma  be- 
lieved that  the  uterus,  by  compressing  the  ureters,  produced  thus  a  urinemia.  This  is  disi)roved 
for  the  majority  of  eclamptics  by  postmortem  examination,  as  it  occurs  in  loss  than  10  p(>r  cent,  of 
the  cases.  Dcloro  suggested  that  bacteria  might  be  the  cause  of  the  toxemia.  Various  bacteria 
were  found  in  the  blood  and  tlie  phicenta  by  Doleris,  Blanc,  and  Favre.  G(>rdes  found  a  bacillus 
which  ilofmeister  proved  to  be  the  common  protons,  and  Cdoy  found  the  Staphylococcus  aureus 
and  albus.  The  froquoncy  of  sepsis  after  ochimpsia,  the  fohrilo  natun>  of  tho  disoaso,  the  fact  that 
it  may  follow  an  attack  of  tonsillitis,  that  it  occurs  oftener  in  cold  and  dami)  weather,  would  argue 
for  an  extraneous  microbic  origin.     Stroganov  states  that  eclampsia  is  an  acute  infectious  disease 


THE  TOXEMIAS  OF  PREGNAN'CY  357 

iiit  rod  need  llin)Uj:h  tin-  luii^'s.  Many  ca.si  s  of  jjroviously  healthy  women,  who,  after  a  few  days  of 
imxlroiiial  symptoms,  develop  eclampsia,  tend  to  make  sueh  a  liypothesis  ven*  prohable.  How- 
ever, Uj)  to  the  |)resent  no  one  lias  been  al)le  to  isolate  a  )ienn  that  eould  he  eonsidered  eausjitive. 
Albert  and  .Miiller  believe  that  the  infection  is  in  the  jjenitals,  and  the  toxins  pro«luced  there,  aa 
from  an  endometritis,  are  absorbed  and  cause  the  <-on\iilsi(jns. 

Bouchard,  in  1SS7,  broke  new  tiround  when,  in  his  "Le^-ons  BUr  les  Anto-intoxieations,"  he 
advanced  the  theory  that  eclampsia  results  from  the  accumulation  of  retained  waste,  which  tlie 
einun<-torii's  faile(l  to  fjet  rid  of.  His  pupil,  Hiviere,  belicvi-d  that  an  overpnwiuction  of  t(ixin8 
occurred  duriiif^  i)re>inancy;  that  this  was  favored  by  liyperenna  of  the  kidneys  and  liver,  and  that 
these  poisons  damajied  tlie  kidneys.  HescMinht  t<j  jirove  the.se  theories  by  determining  the  toxicity 
of  the  blood  and  urine  in  the  eclamptic  and  non-eclamptic  gravida.  Other  authors,  Vollhard, 
Schumacher,  and  Stewart,  disproved  these  theories. 

Then  the  liver  was  accused.  I'inard  and  BoufTe  fie  Saint-Blai.se,  arKU<'<l  that  eclampsia  wjia. 
a  hepatotoxemia  due  to  liver  insuliicieiicy.  .\lilfeld  and  Schmorl  have  found,  in  ca.s<-s  of  typical 
eclampsia,  pathologic:  conditions  which  strongly  resemble  tho.se  of  acute  yellow  atrophy  of  the 
liver. 

Lange  believed  that  the  thyroid  ^land  ha.s  much  to  do  with  eclampsia,  and  by  administorinK 
iodothyrin  he  cured  the  albuminuria  of  the  kidney  of  prejinancy.  Nich(jl.son  and  others  liave  (»!>- 
tained  favorable  results  with  thynjid  extract,  but  the  theory  has  not  awakened  general  interest. 
That  eclamjjsia  may  be  due  to  the  disturbance  of  balance  between  two  organs  with  internal  s<'cre- 
tions  which  should  neutralize  each  other  is  an  attractive  but  abscjiutely  unproved  liyjKjthesis. 
The  parathyroids  (N'a.ssale)  lia\e  been  suji^ested,  the  ovaries  (I'inard),  the  corpus  lutr-um,  an(l 
the  mamma-  (Sellheim),  but  not  yet  the  liyi)()pliysis  cerebri.  The  theory  of  \'eit,  the  dei)ortation 
and  .solution  of  .syncytium,  without  the  production  of  suHicient  antisyncytioto.xin,  remains  still  a 
theory. 

Numerous  investigators  have  tried  to  find  a  to.xin  in  the  placenta,  but  Frankl,  in  summing  up 
their  efforts  and  his  own,  decides  that  there  are  no  toxins  in  the  placenta,  but  that  there  may  be 
f(>rments,  and  .says  that  this  line  of  study  will  more  likely  lead  to  u.seful  results.  (Seeal.so  Holland.) 
Eclampsia  has  been  held  a  form  of  anaphylaxis  due  to  the  introduction  of  a  foreign  protein. 

It  has  long  been  ob.served  that  the  blood  of  eclamptics  contains  an  excess  of  fibrin  (Dienst). 
This  is  probably  not  the  cau.se  of  the  disea.se,  l)ut  is  one  of  th<'  elTects  of  the  common  cause.  The 
same  may  be  .saitl  of  the  high  arterial  ti-nsion  usually  foimd  early  in  the  di.sejuse. 

The  idea  that  the  chiM  ami  placenta  may  be  the  origin  of  the  toxins  is  not  new.  .Vhlfeld 
mentioned  it  in  iSOf,  and  Fehling  and  Collman  support  this  view.  The  autlior  has  flelivered 
disea.sed  children  from  eclamptic  mothers,  and  entertains  no  doubt  but  that  the  fetus  can  sickc-n 
indejiendently  of  the  mother  and  secondtirily  infect  her,  or  after  delivery  continue  ill  and  die.  It 
is  more  than  jirobable  that  certain  ca.ses  of  eclampsia  without  albuminuria  and  other  evidences  of 
renal  disease,  and  ca.ses  of  nephritis  or  toxemia  developing  without  warning  in  previously  healthy 
women,  may  be  found  to  be  due  to  a  di.sea.sed  ovum.  Bouffe  de  Saint-Blaise  in  1SS,S  sawaca.se  of 
eclampsia  in  a  molar  pregnancy,  llitschman  saw  another  in  a  girl  jjregnant  four  and  one-half 
months  with  a  hydatid  mole.  'I'lie.se  may  be  confirmatory  of  the  above,  or  tlu'V  may  mean  that  a 
live  fetus  is  not  necessary  for  the  production  of  the  convulsions.  Eclampsia  may  occur  with  a 
macerated  fetu.s,  though  usually  the  chilil  dies  as  the  result  of  the  toxemia,  and  then  the  condition 
of  the  mother  improv<'S.  Poi.sons  excreted  by  the  fetus  reach  the  general  circulation  witliout 
pa.ssing  through  the  liver,  and  jK-rhaps  the.se  unoxidized  excreta  irritate  the  kidneys,  which  are  not 
able  to  throw  them  olT  in  this  state.  Changes  i<lentical  with  tho.se  found  in  tln'  eclamptic  mother 
have  been  found  in  the  fetus  al.so  dead  of  convulsions  (Bar,  Knapp,  Dienst.  and  DeLe*').  Zwcifel 
h;us  found  sarcolactic  acid  in  the  urine  of  17  eclamptics,  in  the  blood,  and  in  the  fetal  blood.  It  was 
absent  from  the  urine  of  a  case  of  pure  uremia,  but  present  in  the  blood  of  all  children  born  liead 
anil  in  all  the  placenta*  examined.  The.se  experiments  are  in  line  with  the  newer  theories  of  acid 
intoxication.  Zweifel  lias  not  proved  that  the  lactacidemia  is  the  cau.se  of  eclampsia — only  that 
the  lactic  acid  is  present  in  the  urine  of  eclamjjtics.  This  hnding  occurs  also  in  ca.ses  of  as|)hyxia, 
dyspnea,  exhaustion  from  severe  physical  efTort,  .some  febrile  conditions,  ami  poisoning  by  mor- 
phin,  curare,  strychnin,  veratrin,  cocain,  phosphorus,  etc. 

Since  Haver  and  Lever  (1.S4I1)  proved  the  presence  of  albumin  in  the  urine  of  eclamptics,  and 
later  students  found  the  indications  of  a  nephritis  almost  invariably  in  the  urine,  the  idea  gaininl 
ground  that  eclamjjsia  was  allied  to  uremia.  Carl  Braun  .said  the  convulsions  were  dui>  to  acute 
renal  insulHciency.  While  at  autop.sy,  or  in  the  urine,  one  will  rarely  mi.ss  «'vidences  of  nephritis 
(Ingerslev  and  Chari)entier  have  found  2.")()  ca.ses  in  the  literature  without  them),  still  the  weight 
of  clinical  and  postmortem  e\idence  is  against  the  view  that  kidney  ili.sea.s4'  is  the  cau.s*'  of 
eclampsia.     It  is  more  likely  a  result  of  the  action  of  another  cau.se,  and  is  secondary,  not  primar\'. 

Studies  of  the  maternal  metabolism  show  that  tin-re  is  an  all(-ration  in  nitn)genous  catal>- 
olism.  It  has  long  Ix-en  known  that  th(-re  is  a  d<-crea.se  of  the  total  un-a  output,  but  n^c«-nt  stutlif>s 
by  Whitney  and  \\  illiams  show  that  the  amount  of  ammonia  nitrogen  equals  or  even  exccc<is  the 
urea  nitrogen  in  tin-  urim-.  It  is  possible  that  study  of  the-  metabolism  will  lead  us  to  as4jlution  of 
the  probl(-m,  l)ut  nothing  of  great  value  has  y(-t  been  disc-overeil. 

.\mmonium  carbonate  (Spiegelberg),  carbamic  acid  (Ludwig  an«l  Savor),  or  leukoniain.s 
(Ma.ss(-n)  (-in-ulating  in  the  blood  are  mere  theories.  It  would  lead  U3  too  far  to  go  deeper  into 
this  mass  of  hypotheses. 

The  tlu>ory  that  (H'hinipsiia  is  ihir  to  an  into.xicatioii,  is  a  toxoinia.  is  most 
gonerally  accepted,  while  it  is  athiiitted  tliat  the  source  ami  tlie  nature  of  the  jwisons

bacterial  activity  or  from  any  other  source,  it  would  hv\p  our  treatment  immensely, 
but  as  j'Ct  we  are  groping  blindly,  empirically. 

The  Cause  of  the  Convulsion. — Here  again  there  is  nnich  room  for  speculation. 
"Without  doubt  the  ner\'ous  system  of  the  pregnant  woman  is  in  a  state  of  hyper- 
excitability.  This  may  easily  be  determined  l)y  testing  the  exaggerated  reflexes. 
Perhaps  this  is  another  result  of  the  toxemia  of  pregnancy.  Older  writers  classed 
eclampsia  as  a  neurosis  (Dubois),  and,  in  fact,  it  is  more  common  in  neurotic  women. 
Diihrssen  explains  the  convulsions  as  being  due  to  a  spasm  of  the  blood-vessels  of 
the  brain,  the  liver,  or  the  kidneys,  from  an  irritation  proceeding  from  the  uterus.

Spasm  of  the  vessels  of  the  })rain  causing  acute  anemia  and  edema  may  cause  the 
fits,  and  analogy  is  drawn  from  cases  of  epilepsy.  One  need  not  go  far  for  an  ex- 
planation of  the  convulsions  if  the  toxemic  theory  is  proved, — the  toxins  irritate  the 
nerve-centers,  as  do  other  specific  poisons,  strychnin,  tetanus,  etc., — but  the  toxin 
of  eclampsia  has  a  special  affinity  for  the  cortex  of  the  forepart  of  the  brain,  as  is 
shown  by  the  constancy  of  convulsions  and  coma  and  the  mental  symjitoms. 
Individual  convulsions  in  a  case  of  eclampsia  may  be  elicited  l^y  any  external  irri- 
tant, for  example,  jarring  of  the  bed,  slamming  of  doors,  bright  lights,  external  or 
internal  examination,  the  induction  of  labor,  a  hypodermic  injection,  an  enema, 
catheterization,  delivery  of  fetus,  etc.

cially  in  those  cases  which  had  been  given  large  doses  of  chloroform  and  chloral,  a  fact  which  warns 
to  care  in  the  administration  of  these  drugs.     There  may  be  subpericardial  hemorrhages. 

Tliromboses  and  emboU  in  fine  vessels  are  very  common  in  the  lungs,  liver,  kidneys,  brain, 
and  skin;  they  consist  of  Uver-cells,  endothelium,  and  syncj-tium.  The  last  has  no  significance, 
being  found  in  normal  puerpera?.  During  life  the  blood  contains  an  excess  of  fibrin  and  coagulates 
very  quickly,  so  that  often  it  is  impossible  to  perform  venesection  properly.  i\Iicroscoj)ic  findings 
of  the  blood  in  eclampsia  are  not  constant.  The  reds  are  sometimes  increased  (in  one  instance  to 
9,000,000),  which  is  due  to  the  concentration  of  the  blood,  and  there  is  marked  leukocytosis  (40,000), 
e.specially  noted  in  the  multinuclears. 

The  Lungs. — ^Almost  always  congestion  and  edema  are  found,  and  very  often  hemorrhages, 
which  are  usually  under  the  pleune.  Bronchopneumonia  is  not  rarely  found,  due  to  admission  of 
food-particles,  blood,  slime,  etc.,  into  the  air-passages — aspiration  pneumonia.  Septic  pneumonia, 
and,  oftener  in  general  hospitals,  croupous  pneumonia,  may  be  the  cause  of  death.  Gangrene  of 
the  lung  is  sometimes  the  cause  of  death.  Small  arterial  and  venous  thromboses  and  emboli  of 
fat,  liver-cells,  decidual  cells,  and  cells  that  look  like  hypertrophied  nuclei  of  lymphoid  cells  of  the 
bone-marrow,  that  is,  syncji;ium,  are  constant  findings.  These  are  not  characteristic,  occurring 
in  other  conditions. 

The  Fetus. — Bar  and  others  have  found  changes  in  the  child  which  correspond  very  closely 
with  those  in  the  mother,  especially  when  the  child  died  of  convulsions. 

Diagnosis. — Convulsions  and  coma  during  pregnancy  may  come  from  brain 
tumors,  tubercle,  apoplexy,  meningitis,  pneumonia,  epilepsy,  hysteria,  phosphorus, 
strychnin  and  other  poisonings,  uremia,  and  true  eclampsia.  Characteristic  for 
true  eclampsia  are  repeated  convulsions  "wdth  coma,  or  at  least  lethargj^,  between 
them,  early  fever,  and  marked  albuminuria,  with  other  findings  of  renal  involvement. 
The  histor}^  of  the  case  a^III  almost  alwaj's  exclude  poisoning,  but  medicolegallj'  a 
differential  diagnosis  may  occasionally  be  necessary,  and  this  may  not  alwaj^s  be 
possible,  even  at  autopsy,  because,  for  example,  the  liver  in  cases  of  phosphorus 
death  resembles  acute  yellow  atrophy.  Epilepsy  is  eliminated  by  the  history  of 
previous  convulsions,  but  the  first  attack  of  a  permanent  neurosis  maj'  occur  during 
labor,  or,  as  occurred  in  a  case  of  the  author,  epilepsy  maj'  be  inaugurated  by  an 
attack  of  eclampsia,  a  fact  which  was  also  noted  by  Fere.  The  contracted  pupils 
and  diminished  or  absent  reflexes  are  good  points  in  favor  of  epilepsy.  Epileptic 
attacks  seldom  occur  during  pregnancy  and  labor,  and  are  usually  single,  but  the 
status  epilepticus  may  cause  trouble  in  making  the  differential  diagnosis.  Here  the 
slight  or  absent  urinary  findings,  the  late  presence  of  fever,  diminished  reflexes, 
and  the  history  must  help. 

Hysteria  wall  cause  no  trouble  to  an  observer  who  has  seen  both  conditions. 
An  atypical  convulsive  seizure,  lasting  a  long  time,  with  grotesque  motions  and 
spastic  contractions  of  muscle  groups,  retained  consciousness,  and  mobile  pupil, 
without  c^^anosis  or  stertorous  respiration  or  fever,  or  urinary  findings,  serve  to 
make  the  differentiation  easy. 

Organic  disease  of  the  brain  must  be  diagnosed  by  the  usual  medical  methods, 
but  mistakes  are  very  liable  to  occur  in  cases  of  meningitis,  tul^ercle,  and  apoplexy. 
Spinal  puncture  may  be  required.  The  Wassermann  reaction  may  not  be  used  in 
differentiation  because  it  has  been  found  in  8  cases  of  true  eclampsia  bj-  Semon. 
The  treatment  must  be  carried  out  on  obstetric  lines. 

From  uremia  it  is  impossible  to  separate  true  eclampsia  unless  the  preexistence 
of  nephritis  is  known,  but  often  the  general  picture  of  the  case  impresses  the  ob- 
server as  one  of  renal  insufficiency,  and,  again,  another  case  gives  almost  indubitable 
signs  that  the  liver  is  at  fault.  Delirium,  jactitation,  jaundice,  and  petechiie  point 
to  hepatic  involvement.     Treatment  in  all  cases  is  the  same. 

Prognosis. — Over  20  per  cent,  of  women  afflicted  Anth  eclampsia  die,  and  this 
has  been  hardly  affected  bj"  changes  of  treatment  in  the  last  one  hundred  years. 
Wyder  collected  large  statistics,  and  showed  a  general  mortality  of  20  per  cent,  and 
a  mortality  of  10  per  cent,  of  cases  which  developed  in  the  maternities.  The 
prognosis  varies  in  different  countries,  in  different  years,  and  to  a  certain  extent 
with  different  operators.  Statistics  vary  from  5.31  per  cent.  (Stroganov)  to  45.7 
per  cent.    (Buttner)   for  the  mother,  and  from  30  to  42  per  cent,  for  the  child. 


THE   TOXEMIAS    OF    PREGNANCY  30 1 

(Sec  Peterson.)  AMmii  attacked  by  true  eclampsia  multipara*  probaljly  are  no 
more  endangered  tlian  i)riinipara%  hut  since  renal  disease  is  more  common  in  them, 
the  prognosis  is  usually  worse  when  convulsions  cjccur.  Eclampsia  occurring  during 
pregnancy  has  the  highest  mortality,  tluring  labor  less,  and  during  the  puerperium 
the  least,  but  the  experience  of  the  individual  observers  may  be  otherwise,  a-s  in  the 
author's  cases  the  worst  have  In-en  those  where  the  attacks  Ix-gan  postpartum. 

For  the  child  the  chances  are  not  good,  nearly  one-half  of  the  children  djing, 
a  result  that  is  due  to — (Ij  Prematurity;  (2)  toxemia;  0^)  asphyxiation  by  the 
repeated  convulsions  of  the  mother,  with  prolonged  cyanosis;  (4)  drugs  (morphin, 
chloral)  administered  to  the  mother;  (5)  injuries  sustained  during  birth,  especialh' 
forced  ilelivery.     The  child  may  die  of  eclampsia  after  delivery. 

One  nuist,  theiefore,  in  individual  cases  give  a  very  guarded  prognosis,  even  in 
the  apparently  favorable  ones,  because  death  may  occur  in  ccjina  after  one  or  two 
convulsions.  Death  comes  from  exhaustion,  heart  failure,  toxemia  (the  .system 
being  ov(>rwhelmed  by  the  jioison,  such  cases  being  evidenced  by  deep  coma,  with 
few  or  no  convulsions),  eml)olism,  thrombosis  of  the  i)ulm(jnary  artery,  fat  embolism 
of  the  lungs,  hemorrhage  into  the  brain,  pulmonary'  edema,  ccdema  laryngis,  and 
asphyxiation.  Further,  the  patient  is  endangered  by  the  results  and  accidents 
of  severe  operations  undertaken  to  deliver  her,  as  ruptura  uteri,  postpartum  hemor- 
rhage from  cervix  tear,  and  from  sepsis.  Infection  is  a  common  cause  of  death, 
and  eclamptics  show  a  decided  susceptibility  to  it. 

In  individual  cases  the  pulse  is  the  best  index.  If  it  remains  full  and  hard, 
below  120,  there  is  no  immediate  danger,  but  if  fa.ster,  weak,  compressible, 
or  even  running,  the  prognosis  is  bad.  High  fever  is  not  necessarily  a  bad  prog- 
nostic sign  unless  it  runs  above  104°  F.  and  is  going  higher.  Symjjtoms  of  edema 
of  the  lungs,  rattling  in  the  chest,  bloody  froth  from  the  mouth  and  nose,  with 
cyanosis,  are  usually  precursors  of  death,  but  may  respond  to  treatment.  Pro- 
longed and  \nolent  fits  or  freciuently  repeated  attacks  with  short  intervals,  or  both, 
give  a  bad  outlook,  but  recovery  has  occurred  after  <S1  attacks,  though  this  is 
unusual.  When  the  number  exceeds  20,  the  prognosis  gradually  becomes  worse. 
If  the  severity  of  the  symptoms  abates  after  delivery,  the  woman  usually  gets  well. 
Rarely  is  there  a  recurrence  of  the  fits  after  hours  or  days,  and  if  there  is,  recovery' 
is  the  rule.  Such  cases  are  likely  to  show  a  large  numlxT  of  attacks,  for  example: 
Jardine,  207;  Engelman,  200.  It  is  doubtful  if  these  were  true  eclampsia.  Deep 
cyanosis  between  attacks  is  an  unfavorable  symjitom,  as  also  is  extreme  jactitation. 
Anuria  and  intense  albuminuria  are  of  bad  omen,  and  more  hojic  is  justified  as  soon 
as  the  kidneys  show  signs  of  recovery.  Apojilexy  is  almost  always  fatal,  but  some- 
times part  of  the  Ixxly  will  ])e  paretic  or  paralyzed  from  a  focal  edema  which  dis- 
appears during  convalescence. 

After  delivery  the  puerpera  is  not  out  of  danger.  Aspiration  jineumonia  is 
not  rare,  the  result  of  slime,  blood,  food,  etc.,  being  drawn  into  the  lungs  by  the  deep 
stertorous  respiration.  The  tongue  may  be  so  .severely  bitten  during  the  fits  that 
it  may  become  .so  swollen  as  to  ilemand  intubation  or  tracheotomy  to  prevent 
suffocation.  Pneumonia,  too,  may  result  from  t\w  infected  bitten  tongue.  Sepsis 
is  common,  and  usually  runs  a  severe  course,  since  the  kidneys  anti  liver  are  already 
diseased. 

After  delivery  the  all)umin  ([uickly  diminishes  in  amount,  and  may  have  been 
reduced  to  a  trace  by  the  time  the  j)uerpera  leaves  her  bed,  disajipearing  entirely 
in  from  three  to  twelve  weeks.  A  longer  i)ersistence  of  the  urinary  findings  indi- 
cates permanent  damage  to  the  kidney  parench\ina,  and  one  should  l>e  guarded  in 
prognosis.  In  subsequent  pregnancies  albuminuria  and  casts  may  recur,  even 
convulsions  (Diihrssen,  l.o  per  cent.),  but  we  must  decide  that  a  chronic  though 
latent  nephritis  has  existed  in  the  mean  time.  Many  authors  Ix'lieve  that  one  attack 
of  eclampsia  confers  immunity,  but  such  i<  not  the  ease.     Even  the  kidney  df  i)reg-

nancy  may  recur.  It  has  been  held  that  the  kichicy  of  pregnancy  never  left 
permanent  changes  in  the  organs.  This  statement  can  be  neither  questioned  nor 
proved,  because  it  is  never  possible  to  tlemonstrate  al)solutely  that  the  woman  did 
not  carry  into  her  pregnancy  a  latent  nephritis,  dating,  i)erhaps,  from  a  scarlatina 
or  infection  in  infancy. 

Treatment. — Prevention. — One  can  speak  of  rational  i)rophylaxis  only  when  the 
cause  of  disease  is  known.  Since  we  do  not  know  the  causc^  of  eclampsia,  our  treat- 
ment is  all  empiric.  Even  so,  more  can  be  accomplished  by  prevention  than  by 
treatment,  because  after  the  convulsions  have  set  in  the  nervous  balance  is  over- 
thro\\Ti.  We  cannot  prevent  the  action  of  the  primary  cause  of  the  eclampsia, 
but  by  carefully  watching  the  pregnant  woman  we  may  discover  the  first  manifesta- 
tions of  the  action  of  such  noxious  influences,  and  by  appropriate  measures  either 
ward  them  off  entirely  or  interrupt  the  pregnancy  before  the  disease  reaches  a  climax. 
It  is  the  pregnancy  that  favors  the  development  of  eclampsia.  If  we  cannot  pre- 
vent and  cure  eclampsia,  we  can  remove  the  pregnancy.  If  the  earliest  signs  of  the 
impending  catastrophe  can  be  detected,  emptying  the  uterus  will  almost  invariably 
prevent  a  fatal  issue. 

The  prevention,  in  a  general  way,  is  equivalent  to  the  conduct  of  the  hygiene 
of  pregnancy.  Every  pregnant  woman  should  be  considered  a  possible  candidate 
for  eclampsia,  and  all  our  efforts  should  be  directed  to  save  her.  Greater  watch- 
fulness is  imperative  if  the  family  history  presages  trouble,  for  example,  if  the  mother 
had  eclampsia,  if  the  parents  were  neurasthenic,  insane,  or  alcoholic,  these  indicating 
a  hereditary'  instability  of  the  nervous  system  which  may  lead  to  disorders  of 
metabolism,  especially  during  the  crucial  test  of  pregnancy.  The  personal  history 
is  important;  for  example,  if  the  patient  had  eclampsia  or  declared  renal  disease 
before;  if  she  has  had  diseases  which  may  have  damaged  kidneys  or  liver,  especially 
the  acute  infections;  if  she  is  of  a  'H^ilious  type,"  one  is  on  the  lookout. 

If,  in  spite  of  the  hygienic  rules  laid  do^\Ti  for  the  patient,  the  symptoms  of 
toxemia  appear,  or  if  the  urine — which  should  be  examined  as  a  routine  duty 
every  two  weeks  in  the  latter  months  of  pregnancy — shows  evidences  of  deficient 
renal  activity,  the  patient  is  put  on  a  strict  prophylactic  regimen.  Albuminuria  is 
the  most  important  finding,  and,  in  the  author's  experience,  is  never  marked  without 
toxemic  s^Tuptoms.  Diminished  daily  amount  of  urine  and  decrease  of  total  solids 
are  next  in  importance.  Casts,  unless  granular  and  cellular,  are  not  unusual  in  the 
urine,  but  they  may  not  be  numerous  without  exciting  suspicion;  white  and  red 
blood-corpuscles  with  renal  epithelium  show  the  acuteness  of  the  process.  The 
percentage  of  urea  is  not  a  reliable  index  of  the  nearness  of  the  attack,  but  it  is  a 
valuable  adjunct  to  the  diagnosis,  since  when  a  woman  passes  less  than  half  the 
amount  of  urea  considered  normal  and  has  all^uminuria,  we  can  suspect  derange- 
ment of  the  liver  and  kidneys.  If  the  urea  steadily  diminishes  while  the  albumin 
increases,  the  danger  signs  are  unequivocal.  In  suspected  cases  weekly  and  even 
daily  examinations  of  the  urine  are  made.  As  stated  in  the  chapter  on  the 
Hygiene  of  Pregnane}',  all  gravidas  are  requested  to  notify  the  physician  if  any 
untoward  symptoms  arise,  and  the  accoucheur  should  give  these  women  a  large 
amount  of  personal  attention,  because  the  symptoms  will  show  that  trouble  is 
brewing  long  before  the  urine  discloses  the  fact. 

When  the  first  signs  or  symptoms  of  toxemia  occur,  treatment  must  be  at  once 
instituted.  It  will  proceed  along  three  lines:  (1)  The  diet  should  be  so  ordered 
that  just  enough  nitrogenous  matter  is  given  to  sustain  life,  in  the  form  easiest 
assimilated,  and  that  will  leave  the  least  amount  of  waste  and  by-products,  wliich 
throw  extra  w^ork  on  the  liver  and  kidneys.  (2)  The  emunctories  shoukl  be 
stimulated  to  throw  off  the  surcharge  of  poisons  already  in  the  blood.  (3)  Should 
the  above  treatment  not  have  the  needful  effect;  should  the  evidences  of  renal  in- 
sufficiency increase;  or  should  the  signs  of  a  real  nephritis  appear,  the  induction  of 
premature  labor  is  not  only  justifial)le,  but  imperatively  indicated.

diet.  Spiees,  tea,  coffee,  alcoholics,  beef,  v«'al,  muttcjii,  and  jxjrk  are  strictly  fort>idden.  Water  is 
given  in  lar^je  amounts  unless  the  heart  is  already  overloade<l.  Huttermilk.  inatzoon,  anil  kumLss 
are  recommende<l.  My  experience  witli  a  salt-free  diet  hits  be<-n  di.sai)|M)inlinjj.  The  e«lema  was 
somewhat  les-seiu-fl  by  it,  but  the  conilition  of  the  patients  was  not  materially  improve<l. 

(2)  ( >ne  may  increa.se  excretion  by  the  bowels,  the  kidneys,  the  .-kin,  and  the  lun>:s.  A 
bri.sk  .saline  |)urne  is  given  at  the  start,  and  tiie  bowels  are  kept  open  by  s;ilin«>s,  alternating  with 
vegetable  cathartics,  since  continuous  administration  of  the  former  leads  to  anemia  and  headachetJ. 
Water  is  administere<l  morning  and  night  on  an  empty  stomach.  It  is  both  la.xative  and  <liuretir. 
Diuresis  is  favored  by  the  ingestion  of  liciuids,  especially  hot  water  in  large  amounts.  Thi.s,  in 
combination  with  the  milk  <liet,  do<'s  not  fail  to  pnxluce  iMjIyuria.  Huttennilk  is  al.s<j  given,  but 
the  vegetable  diuretics  ami  diuretin  are  not  recommcn<le<l. 

The  skin  is  to  be  kept  free  from  chill  by  woolen  undergarments,  which  should  b«'  worn  even 
in  summer.  If  the  symptoms  of  to.xemia  are  urgent,  hot  wet  j)acks  twice  daily  are  onh-r*"*!.  A 
word  of  warning  here:  patients  with  weak  hearts  may  die  in  such  a  sweat,  for  which  rea.son  <-areful 
watching,  handy  stimulants,  and  oxygen  are  deman<le<l.  Some  authors  condemn  sweating  in  th<se 
cases  and  in  eclampsia,  claiming  that  it  is  too  depressing,  that  it  concentrat<s  tlie  poi.s<)n  in  the 
blood,  and,  on  the  other  liand,  tlie  amount  of  to.xin  removinj  is  inconsiderable.  The  author  mak«>s 
very  little  u.se  of  .sweats.  Jaborandi  is  lieartily  condemne<l,cven  wlu'U  the  patient  is  con.<cious, as  it 
is  dangerous  and  unneces.sary.  Of  drugs,  the  author  uses  few.  Hexamethyleriainin,  5  grains  four 
times  daily,  in  two  ca.ses  .seeme<l  to  do  good,  but  the  author  wi.shes  more  experience  bofon-  recom- 
mending it.      It  was  given  on  the  bacterial  theory  of  toxemia. 

A  valuable  means  for  starting  the  skin  and  kidneys  is  the  .subdemial  injection  of  0.7  jkt  cent, 
salt  .soluticjn.  It  is  used  only  in  the  advance<l  cases,  when  eclampsia  is  threatt-ning  and  riuick 
action  is  nce<led.  Fresh  air  in  abundance  aids  excn-tion  by  the  lungs,  and  the  patient  is 
instructed  to  fill  and  empty  the  lungs  by  very  tleep  breaths  in  fresh  air  ten  times  each  morning  and 
evening. 

When  treatment  faithfully  carried  out  on  the  lines  here  laid  down  ha.'^  failed  to 
produce  sufficient  amelioration  of  the  symptoms,  if  the  evidences  of  renal  insuffi- 
ciency persist  or  grow  worse,  and  especially  if  a  tendency  to  sleep,  twitchiufis.  or 
other  symptoms  of  eclamp.sia  threaten,  the  pregnancy  shouUl  l>e  terminated. 

The  .symptoms  that,  in  my  opinion,  most  surely  indicate  the  near  approach 
of  convulsions  are:  Headache,  occipital  or  frontal;  seeing  colored  lights  or  "span- 
gles"; amaurosis  or  changes  in  the  retina  seen  with  the  ophthalmo.-^cope;  twitch- 
ing of  the  mu.scles;  .somnolence  or  in.somnia;  naus<*a  and  vomiting;  pain  in  the 
epigastrium;  subicterus;  general  edema  of  the  body;  high  arterial  tension  and 
marked  albuminuria.  Rarely  one  or  the  other  .symptom  will  stand  out  very  prom- 
inently, or  .several  may  be  absent.  Marked  leukocytosis  is  al.'^o  .^significant,  and  in 
doubtful  ca.ses  the  permeability  of  the  kidneys  could  be  tested  with  the  ])henol- 
suli)hophthalein  and  other  tcst.s,*  though  thus  far  the  results  are  not  of  any  great 
value. 

How  long  one  should  wait  to  see  the  effects  of  treatiueiit  deix  nils  on  tlu'  imli- 
vidual  case  and  on  the  attendant's  experience,  but  the  final  proof  of  our  deep  ignor- 
ance of  the  nature  of  these  affections  is  brought  by  th«'  fact  that  .«sometim<>s.  wlu-n 
these  patients  go  untreated,  eclamjjsia  tloes  not  occur,  and  wlun  treatment  has 
l^roiluced  apiiarent  cure,  the  convulsions  occasionally  manifest  themselves,  as  in

was  successfully  delivered,  but  three  days  i)ostpartimi  ((.nvulsions  developed 
and  death  ensued.  Eclampsia  is  not  always  a  preventable  disease,  as  Davis  and 
Ed:iar  claim,  a  view  which  is  supporteil  by  Williams.  As  yet  we  have  no  certain 
index  of  impt'n.ling  eclamj^sia— all  we  can  say  is  that  the  gravida  presents  the  syn- 
drome of  a  disease  in  which  convulsions  are  the  usual  termination,  and  that  it  is 
wisest  to  terminate  the  pregnancy,  the  ultimate  cause  of  the  di.-turbance.

cervix  by  packing  it  and  the  lower  uterine  segment  with  gauze  for  from  twelve  to  twenty  hours. 
Pains  are  elicited,  the  tissues  softened,  and  the  chances  of  injiuy  to  tlie  cer\ix  and  danger  to  the 
fetus  diminished.  After  removal  of  the  gauze  the  membranes  are  ininetured,  the  liquor  amnii  is 
allowed  to  drain  off,  and  then  a  colpeurynter  is  inserted,  wliich  evokes  strong  i)ains  and  completes 
the  dilatation,  so  that  when  the  bag  is  expelled  the  cliild  soon  follows.  (See  Induction  of  Labor.) 
After  labor  has  been  inaugurated  it  should  be  terminated  as  soon  as  the  conditions  will  permit,  as 
experience  has  shown  that  eclampsia  is  less  likely  to  occur  postpartum  after  a  quick  deliver}'. 
The  pains  seem  to  elicit  convulsions  in  some  cases,  and  if  eclampsia  is  very  imminent,  it  may  be 
best  to  select  an  operation  which  empties  the  uterus  in  one  sitting.  Accouchement  force  (forced 
delivery  after  rapidly  tlilating  the  cervix  by  steel  dilators,  bags,  or  the  hands,  in  one  sitting)  is  to 
be  condemned,  since  it  is  dang(>rous  to  the  mother  and  fetus.  Deep  lacerations  arc  the  rule,  and 
sometimes  they  extend  into  the  jieritoneal  cavity.  Vaginal  cesarean  section  is  a  better  operation 
in  urgent  cases,  but  sometimes  it  presents  insurmountable  difficulties;  for  example,  the  cervix  will 
not  come  down  b^^  traction  so  that  it  may  be  incised,  but  tears  if  the  attempt  is  forced;  the  broad 
ligaments  may  be  edematous  and  fix  the  uterus  high  in  the  abdomen;  hemorrhage  may  be  so 
■profuse  that  the  field  becomes  dangerous  to  work  in;  even  deep  anterior  and  posterior  incisions 
may  fail  to  produce  sufficient  room  to  deliver  the  child  unmutilated,  because  of  rigidity  of  the  un- 
prepared parts.  If  it  were  possible  to  recognize  beforehand  all  these  difficulties  and  complications, 
the  best  method  of  delivery  would  be  abdominal  cesarean  section.  This  operation  will  rarely  be 
called  for,  because  usually  the  simpler  methods  suffice,  and,  further,  the  abdominal  delivery  has 
shown  a  very  high  mortality.  The  kidnej's  are  much  concerned  in  all  operations  which  open  the 
peritoneal  cavit}',  and  are  likel}^  to  be  severely  affected.  Sepsis  is  much  more  common.  However, 
in  eclampsia  occasionally  a  case  will  occur  where  the  urgency  of  the  sj-mptoms  is  great,  the  cervix 
closed,  high,  hard,  the  patient  a  primipara  with  rigid  vagina  and  perineum,  and  the  abdominal 
dehvery  will  offer  the  easiest  and  safest  solution  of  all  the  difficulties.  Of  course,  a  contracted 
pel\-is,  placenta  prajvia,  or  other  complication  may  alter  the  method  of  procedure. 

The  question  of  anesthesia  deserves  careful  thought.  Formerly  it  was  taught  that  every 
manipulation  should  be  done  under  anesthesia,  because  it  was  feared  that  the  irritation  would 
bring  on  a  con^-ulsion — a  point  emphasized  by  R.  Barnes.  Experience  has  shown  that  anesthetics 
are  particularly  dangerous  in  such  conditions  because  of  their  destructive  action  on  the  kidney,  the 
liver,  and  the  blood.  Ether  is  less  dangerous  than  chloroform,  but  even  this  is  used  only  for  opera- 
tive deliver}'.  The  danger  of  provoking  convulsions  actually  exists,  but  it  is  estimated  to  be  less 
than  the  damage  done  to  liver,  kidneys,  and  blood  by  the  poisonous  narcotics. 

Treatment  of  Eclampsia.  —  AMien  the  pregnant,  parturient,  or  puerperal 
woman  has  had  the  first  convulsion,  the  case  at  once  assumes  a  most  serious 
aspect.  The  nervous  balance  has  been  upset,  and  one  convulsion  is  likely  to 
lead  to  another.  The  mortality  of  eclampsia  is  still  from  20  to  45  per  cent,  for 
the  mother  and  30  to  60  per  cent,  for  the  child.  Such  high  mortalities  rarel}^  ac- 
company surgical  complications,  hence  the  patient  deserves  as  much,  if  not  more, 
consideration  than  does  the  surgical  patient.  She  should  have  at  least  two  physi- 
cians and  one  or  more  good  obstetric  nurses.  If  a  good  maternity  hospital  is  near 
by,  she  should  be  quickly  transported  thither;  if  not,  the  facilities  of  the  maternity 
should  be  closely  imitated  at  home. 

There  are  three  general  plans  of  treatment — two  extremes  and  one  occupying 
a  middle  position.  Duhrssen's  dictum  is — after  the  first  convulsion  put  the  patient 
into  a  deep  sleep  and  deliver  at  once.  The  other  extreme  is,  put  the  patient  to  l:)ed, 
give  narcotics,  stimulate  the  emunctories,  etc.,  and  await  the  natural  termination 
of  pregnancy  and  labor.  Those  accoucheurs  occupying  the  middle  position  use 
the  medical  treatment  more  or  less,  and  hasten  the  labor  only  if  the  patient's  con- 
dition is  evidently  going  from  bad  to  worse. 

Experience  is  accumulating  to  prove  that  the  rapid  emptying  of  the  uterus  in 
deep  narcosis  after  the  first  convulsion  gives  the  best  results.  Carl  Braun  empha- 
sized the  fact  that  the  convulsions  ceased  or  became  less  severe  after  delivery. 
Duhrssen  showed  that  in  93.75  per  cent,  such  a  result  was  found,  and  Olshausen 
showed  85  per  cent.  Seitz  and  Reuben  Peterson  prove  it  conclusively  in  verj-  large 
statistics.  In  the  author's  experience  of  72  cases  the  patients  did  better  after 
early  delivery  so  far  as  the  convulsions  were  concerned,  but  the  proportion  of  actual 
recoveries  was  only  slightly  increased.  Statistics  from  large  material,  however, 
show  a  decided  improvement.  Peterson,  collecting  615  cases  of  early  delivery  (as 
soon  as  possible  after  tlie  first  convulsion),  finds  a  mortality  of  15.9  per  cent.,  and 
compares  this  with  28.9  per  cent.,  the  mortality  in  the  same  maternities  under  so- 
called  conservative  treatment.  Another  table  shows  4  per  cent,  and  31  per  cent, 
respectively.     Another  strong  argument  for  early  dehvery  is  the  larger  number  of

Before  the  scveiitli  nioiitli  all  fhililrcn  die,  and  it  is,  tlien-forc,  n«-e<  ssary  to  onxure  only  enough

If  the  pati«'nt  is  in  a  maternity  in  the  hands  of  a  capable  obstetric  surgeon,  immediate  de- 
livery is  |)ractised,  overcoming  the  resistance  of  the  cervix  and  i)erineum.  In  a  private  home,  with- 
out skille(l  a.><sist ance,  the  accoucheur  had  better  rely  on  medicinal  and  les.s  active  measures — 
I)uncture  of  the  membranes,  the  use  of  the  colpeurynter,  and,  when  only  a  little  of  the  cer\'ix  is 
left,  manual  dilatation. 

If  the  cervix  is  fullv  dilated,  delivery  is  accompli.shed  at  once  l)y  forceps  if  the  head  is  en- 
gaged; by  version  and  immediate  extraction  if  tlie  head  is  above  the  brim.  The  i)ains  in 
eclampsia  are  visually  strong,  and  rapidly  etTaee  and  dilate  the  cervix.  Indeetl,  one  is  sometimes 
surprised  to  find  the  child  dclivfr(<l  under  the  coverlet. 

If  the  cervix  is  efTaceci,  shortened,  taken  uj),  so  that  only  the  thin  e«lge  remains,  this  may  be 
dilated  with  the  fingers,  or  with  any  of  the  metallic  dilators  on  the  market,  or  by  means  of  hydro- 
static bags,  or  the  thin  j)artition  may  be  inci.sed  (Diihrssen's  incisions).  Manual  dilatation  in 
these  instances  is  the  method  of  choice.  After  this,  forceps  or  version  and  extraction  of  the  child, 
depending  on  engagement. 

If  the  cervix  is  tightly  closed,  not  effaced,  the  cervical  canal  long,  the  greatest  diffirulties  are 
met.  Without  doubt  the  vaginal  cesarean  .section,  where  it  can  be  performed,  is  the  best  meth<j<l 
of  delivery  under  these  conditions.  Abdominal  cesarean  .section,  reconmiendiHl  by  Halbertsma 
in  1.SS9,  still  shows  a  high  mortality,  and  while  it  .saves  most  babies,  is  too  grave  an  ri|)eration  to 
be  recommended  except  for  the  worst  ca.ses.  The  authcjr  is  convinced  that  it  has  a  place  in  the 
treatment  of  eclampsia,  and  believes  that  its  field  will  grow  larger  in  time. 

Unless  either  of  these  methods  of  delivery  is  practised,  the  first  local  mterference  to  be  made 
is  the  rupture  of  the  bag  of  waters.  In  many  ca.ses  this  causes  the  convulsions  to  abate,  but  we 
usually  go  ahead  with  other  means  of  effecting  delivery. 

Nianual  dilatation  of  the  clo.secl  cervix  is  an  operation  reqtiiring  from  one  to  three  hours; 
it  is  always  attended  by  laceration  of  the  parts,  which  tears  are  very  often  de<'i),  and  not  seldom 
fatal,  either  from  hemorrhage  or  from  extension  through  the  uterus  into  the  peritoneal  cavity,  or 
from  infection,  and  is,  therefore,  condemned.  The  same  statement  applies  to  the  use  of  Bossi's 
and  other  metal  dilators  when  the  cervix  is  unefTaced. 

Incisions  into  a  closed  cervix  ma}'  not  be  made  unless  the  tjTiical  vaginal  cesarean  section  be 
performed. 

Dilatation  by  bags,  the  colpeurynter  of  Carl  Braun,  the  ineUustic  balloon  of  Chamix^tier 
de  Kibes,  or  its  mollification  b}'  \'oorhees,  can,  in  favorable  ca.s<'s  (soft,  dilatable  cervix),  be 
accomplished  in  one  sitting  under  anesthesia,  lasting  one  to  two  hours,  l)ut  if  the  cersix  is  rigid,  an 
attempt  to  force  it  open  in  this  time  would  fail  if  it  tlid  not  rupture  the  uterus.  In  such  ca.<<>s 
the  patient  must  be  put  to  beil  and  the  action  of  labor-i)ains  awaited.  Only  uterine  action  will 
soften,  efface,  and  safely  dilate  a  hard  cervix.  Infortunately.  rigi<l  cervix  is  a  freijuent  complica- 
tion of  eclamp.sia,  .since  this  conditicm  is  common  in  primipane  and  in  those  of  advance*!  age. 

Often  after  the  bags  have  j)rocured  partial  opening  of  tin-  womb  delivery-  may  Ix"  efTecte<l  by 
vaginal  cesarean  section.  A  rigid  pelvic  floor  must  not  be  overcome  by  brute  force,  since  uncon- 
trollable lacerations  may  result,  and,  too,  the  baby's  head  nuist  not  be  used  as  th«'  forcing  w<Hlge. 
Perineotomy  should  be  done,  the  cut  being  a  bold  one,  through  the  anterior  or  puborectal  iK)rtion 
of  the  levator  ani.     (For  further  jiarticulars  set^  p.  30.5.) 

During  the  delivery  of  eclamptics  extraordinary  precautions  again.st  sep.-is  nujst  be  obs<^rv(-d, 
because  they  are  jiarticuiarly  liable  to  infection,  the  kidneys  and  liver  being  thrown  out  of  inununiz- 
ing  action.  "  In  spite  of  the  most  rigid  precautions  the  author  h:us  s<M'n  fatal  infection  arise.  One 
source  of  trouble  is  feces  streaming  from  the  anus,  th<>  result  of  the  admini.stration  of  cathartics 
anil  enemata  before  delivery.  This  danger  is  .so  great  that  the  author  withholds  such  practice 
until  after  the  uterus  is  emptieil.  If  the  fielil  of  operation  is  constantly  soileil  l)y  di.scharges  from 
the  rectum,  the  anus  should  be  closed  by  a  circular  suture,  which  is  to  be  rcmorcilju^t  before  the  child 
is  (lelircreil. 

What  was  .said  about  anesthetics  in  discussing  prevention  applies  liere.  father  is  recom- 
mended, but  as  little  is  given  as  possible.  .Neither  chloroform  nor  ether  shoultl  be  given  during 
the  attacks,  since  thev  do  no  good,  poi.son  the  patient,  and  overload  the  rtMiin  with  noxious  vai>ors. 
Fattv  heart  is  a  frequent  finding  at  autop.sy  in  tho.se  cjuses  where  chlon)form  hail  b«-«'n  freely  ad- 
ministered. In  the  sixties  chloroform  was  given  continuou.sly  for  hours — once  seventeen  hours, 
by  Simp.son.  Morphin  and  .scojKilamin  have  been  useil,  but  with  indifferent  success.  Recently 
McPherson  recommended  them. 

Hemorrhage  during  delivery,  if  moilerate,  is  not  to  Ix»  checkeil  too  soon,  since  bleeduig  is  one 
of  the  adjuvant  means  of  cure. 

Should  the  perineum  be  torn  during  si>ontaneous  deliver}',  it  may  be  wi.s«T  not  to  give  an 
anesthetic  for  its  repair,  but  to  leave  it  for  future  ojM'ration.  If  the  tear  occurs  in  oix-nitive 
dehvery,  especially  if  a  complete  one,  it  should  be  sutun-*!— at  le:Lst  the  sphincter  .should  b<-  united. 

Adjuvant  Treatment.— FToieciion  against  injury.  Since  the  convulsions  some- 
times show  frightful  vehemence,  the  patient  must  Ix?  quickly  undressed  and  put  to

bed,  surrounded  vath  pillows,  and  watclied  by  a  trained  attendant,  preferably  a 
physician.  False  teeth  should  be  removed.  To  prevent  the  biting  of  the  tongue 
a  simple  device  illustrated  in  Fig.  343  may  be  used.  A  large  wooden  clothespin 
is  wrapped  in  a  thin  handkerchief  and  hung  near  the  head  of  the  bed.  As  the 
attendant  sees  the  attack  approach  it  is  placed  between  the  teeth,  so  that  the 
elasticity  of  the  prongs  takes  up  the  champing  of  the  jaws.  If  the  tongue  is  swollen 
from  injury,  it  may  be  necessary,  to  prevent  asphyxiation,  to  intubate,  using  soft- 
rubber  tubing,  or  to  do  tracheotomy.  Restraint  of  the  movements  should  not  be 
made — all  that  may  ])e  done  is  to  keep  the  w'oman  from  injuring  herself.  Heart 
failure  may  be  induced  by  forcibly  holding  the  patient  still.  For  extreme  and  ex- 
hausting jactitation  morphin  may  be  given,  or,  but  rarely,  an  anesthetic  may  be 
used.  Mucus  in  the  throat  and  mouth  is  to  be  removed  frequently,  but  with  gentle- 
ness, and  it  is  best  for  the  patient  to  lie  on  the  side,  to  allow  the  oral  secretions  free 
escape — an  especially  important  injunction  during  vomiting;  these  precautions 
are  taken  to  prevent  aspiration  pneumonia.  In  the  side  position,  too,  the  swollen 
tongue  falls  forward  and  frees  the  respiration. 

All  irritants  should  be  withheld,  which  means  that  examinations  are  to  be 

omitted,  if  possible,  and  the 
patient  disturbed  only  for  ab- 
solutely necessary  treatment. 
Visitors  should  be  excluded 
from  the  room,  which  should 
]3e  well  darkened,  and  the  at- 
tendants should  move  about 
quietly,  permit  no  loud  talk- 
ing, jarring  the  bed,  etc.  As  in 
tetanus,  these  external  irri- 
tants may  excite  a  convulsion. 
Narcotics . —  Formerly 
chloroform  was  used  for  each 
convulsion,  and  even  contin- 
uously. G.  Veit  introduced  the 
morphin  treatment,  and  von 
Winckel  gave  chloral  in  large 
doses  per  rectum.  Experi- 
ence has  not  sustained  these 
methods,  and,  indeed,  they  are 
only  symptomatic,  since  the  at- 
tacks are  but  a  symptom  of  the 
general  intoxication.  While  the 
frequently  repeated  convulsions  are  a  severe  strain  on  the  heart  and  the  cyanosis 
weakens  both  heart  and  general  system,  still  it  is  the  intoxication  which  is  to  be 
feared,  and  one  should  hesitate  before  adding  other  poisons  to  an  already  overloaded 
circulation.  Without  doubt  chloroform  causes  many  deaths,  by  degenerating  the 
liver,  the  blood,  and  the  heart  muscle  (secondary  chloroform  death) ,  and  morj^hin  in- 
creases the  coma.  The  children  often  die  from  undoubted  morphin  poisoning.  Lum- 
bar anesthesia  has  been  trietl,  but  failed,  and  the  same  result  was  exj^erienccd  with 
lumbar  puncture.  The  author  uses  narcotics  and  anesthetics  as  sparingly  as  possible. 
Elimination. — On  the  theory  that  eclampsia  is  a  toxemia,  one  would  try  to 
get  rid  of  the  poisons  through  the  emunctories.  Experience  has  been  disappoint- 
ing, as,  one  would  expect,  since  the  toxin  is  probably  colloidal,  and  closely  bound 
to  the  nerve-cells.  C'athartics  should  be  withheld  until  the  uterus  is  empty,  be- 
cause of  the  danger  of  infecting  the  operating  field  with  liquid  feces.  After  delivery 
a  full  dose  of  salts,  jalap,  or  castor  oil  is  given,  but  the  patient  is  not  to  be  strongly

purged.  Diapliore'tics,  especially  pilocarpin,  are  t(j  he  eondenined.  Hot  hatlis 
involve  too  much  manipulation,  hut  hot  wet  packs  and  alcohol  sweats  are  recom- 
mended hy  many  authors.  They  should  not  he  used  during  lahor.  hut  afterward 
one  or  two  may  he  given,  though  they  are  tlepressing  and  have  caused  death.  In 
view  of  this  fact,  and  Ix'cause  they  have  not  i)rovcd  of  any  real  value,  the  author 
has  dispensed  with  them.  Another  ol)jection  rai.scd  against  the  jjacks  and  sweats 
is  that  they  concentrate  the  poison  in  the  hlood  and  thus  the  nerve-centers  get  a 
douhle  dose,  while  the  amount  of  poison  thus  eliminated  through  the  skin  is  mininml. 

Medicinal  diuretics  are  too  slow  in  action,  if  they  an-  not  ohjectionahle,  he- 
cause  irritating  to  the  kidneys. 

Diaphoresis  and  diuresis  are  hest  ohtained  i)y  the  free  exhihition  of  liciuids. 
Water  and  lemonade  hy  mouth  and  salt  solution  hypodermically  do  more  to  favor 
the  action  of  the  skin  and  of  the  kidneys  than  any  other  means.  })ut  one  mu.'^t  o\y- 
serve  care  not  to  overload  either  the  stomach  or  the  heart,  accidents  which  the 
author  has  seen  as  the  result  of  overzealousness.  Litjuids  are  administered  to 
unconscious  patients  ])y  stomach-tuhe,  having  due  regard  to  the  amount  given 
and  the  possihility  of  some  of  the  fluid  penetrating  the  bronchial  tubes.  Salt 
solution  is  hest  administered  hypodermically.  a  cpiart  morning  ami  evening.  If 
the  patient  is  very  edematous,  one  should  use  less  water.  The  use  of  salt  does  not 
harmonize  with  some  theories  regarding  edema,  l)ut  practical  experience  shows  its 
value.  Puncture  or  incision  of  the  swollen  limhs  or  swollen  vulva  may  he  indicated, 
under  strict  antiseptic  precautions,  of  course.  Advantageously  combined  with 
hypodermoclysis  is  the  withdrawal  of  hlood. 

Venesection  is  one  of  the  oldest  remedies  for  eclam])sia,  hut  with  the  advent 
of  chloroform  it  lost  its  prestige.  Now  it  is  coming  into  favor  again  as  an  adjuvant, 
antl  hills  fair  to  hokl  a  permanent,  but  secondary,  place  in  treatment.  In  cases  in 
which  the  convulsions  recur  frecjuently  in  spite  of  treatment,  in  which  the  pulse  is 
full  and  strong,  the  face  flushed  or  cyanoti( — in  short,  when  the  picture  might  he 
called  sthenic  or  apoplectic,  hlei'ding  will  tlo  good.  In  ca.ses  of  the  opposite  type 
bleeding  is  a  procedure  of  doubtful  utility.  Stinmlation  is  here  more  tlesirable. 
When  the  evidences  of  cardiac  engorgement  are  jire.sent  and  pulmonary  edema 
threatens,  even  if  the  pulse  is  weak,  l)leeding  with  stimulation  may  tide  the  patient 
over. 

By  withdrawing  a  i)int  of  lilood  one  removes  considerable  poison,  hut  hleeiling 
also  favors  diuresis  and  diaphoresis.  A'enesection  should  l)e  reserved  until  after 
delivery,  since  a  hemorrhage  at  birth  may  make  further  bleeding  unwise.  It  may 
b?  impossil)le  to  get  en(jugh  hlood  from  the  vein,  becau.se  it  clots  so  rapidly  and 
firmly  in  the  incision. 

Oxygen  is  another  adjuvant.  It  siioukl  always  l)e  used  in  the  form  *if  pure 
fresh  air,  anil  a  great  deal  of  it — a  point  frequently  neglected  while  the  oxygen  tank 
stands  in  the  stuffy  room.  Oxygen  is  given  during  the  convulsion  and  right  after 
it,  to  relieve,  as  (luickly  as  jKjssihle,  the  cyanosis,  and  it  is  valuable  also  as  a  heart 
support.  Artificial  respiration  may  he  necessary  to  tide  the  ])atient  over  a  syncope 
following  an  attack,  or  to  improve  the  oxygenation  t-f  the  IjIooiI  between  attacks. 
Part  of  the  coma  is  due  to  hypercarhonization  of  the  blood.  \'eratrum  viride,  first 
used  by  Dr.  Baker,  of  Eufala.  Alabama,  in  1S.')0,  lias  attained  considerable  repute 
in  America  and  Italy  as  a  .<;pecific.  but  large  experience  does  not  sustain  it.  \  era- 
tronc,  an  aseptic  preparation,  is  given  in  10-minim  doses  hy|)odermically  every 
thirty  minutes  until  the  pulse  has  come  ilown  to  00;  then  no  more  is  given  until 
the  pulse  rises  above  00.  In  the  author's  exi>erience  the  drug  has  not  altered  the 
results  either  way,  and  he  seldom  uses  it,  and  then  only  in  the  puerperium. 

Other  remedies,  mentioned  for  the  sake  »»f  completion,  are  thyroid  extract 
(Lange  and  Nicholson);  parathyroid  extract  (Wsale);  alkalis  (Zweifel).  on  the 
theorv  of  acidosis;    amvl  nitrite  (.b-nks);    lumbar  inmcture:    trephining  the  skull; 


368      THE  PATHOLOGY  OF  PREGNANCY,  LABOR,  AND  THE  PUERPERIUM 

amputation  of  the  mamina>  (."^ellheimj ;  injection  of  air  and  oxygen  into  the 
mammae,  as  is  done  for  a  similar  disease  in  cattle  (Gilles) ;  and  renal  decapsula- 
tion (Edebohls).  Both  theory  and  practice  speak  against  the  last  operation. 
Cliirie  collected  30  cases  with  a  mortality  of  46  per  cent.,  and  the  clinical  his- 
tories do  not  show  that  the  decapsulation  improved  the  conditions  ]:)resent  with 
any  regularity,  Littauer  reports  62  cases  with  20  deaths,  which  is  better,  espe- 
cially since  only  the  serious  ones  were  operated.  The  question  of  permanent 
damage  to  the  kidney  from  the  shrinking  of  the  new  connective-tissue  capsule 
requires  solder  consideration.  Dienst  recommentls  hirudin,  an  extract  of  leeches, 
given  intravenously  to  reduce  the  fibrin  content  of  the  blood. 

The  after-treatment  is  on  the  general  lines  just  laid  do^^^l.  Water  is  given  for 
forty-eight  hours,  then  milk  and  water,  or  rice-water  with  strained  gruels,  meat  and 
broths  being  withheld.  Since  tlie  kidneys  now  begin  to  act  freely,  often  140  to 
180  ounces  of  urine  a  day  being  passed,  it  is  well  to  watch  the  bladder  for  over- 
filling. Involuntary  bowel  movements  are  the  rule,  and,  therefore,  the  lochial 
pad  should  be  arranged  so  that  the  feces  do  not  dam  up  into  the  vulva.  Warm- 
water  bags  are  to  be  closely  watched,  because  eclamptics  are  especially  liable  to 
burns  and  necroses.     Sometimes  spontaneous  necroses  resemble  burns. 

Since  the  convulsions  may  recur,  even  after  a  week,  the  puerpera  requires  con- 
stant supervision,  and  especially  if  she  shows  any  signs  of  puerperal  insanity,  such 
cases  not  seldom  making  attempts  at  suicide  or  trying  to  kill  the  child. 

The  temperature  of  the  eclamptic  quickly  subsides,  a  rise  after  such  a  fall 
indicating  sepsis,  pneumonia,  etc.  Nursing  should  not  ])e  allowed  until  the  puerpera 
has  been  fully  conscious  for  several  days  and  the  urine  has  become  nearly  normal, 
and  when  her  strength  permits.  In  a  few  reported  cases  and  one  of  my  o\\ti  it  has 
seemed  that  the  milk  of  the  mother  caused  convulsions  in  the  child.  (See  also 
Goodali.)

CHAPTER  X.WIII 
THE  KIDNEY  OF  PREGNANCY 

Bah.nks  said  that  prcj^iiaiicy  is  the  test  of  bodily  soiindiicss,  and  it  is  Kcnrrally 
admitted  tliat  tlic  kidneys  are:  the  point  of  weakest  resistance  during  this  perio<l. 
\'<)ii  I.eyden  deserihed  certain  changes  in  the  kidney  to  which  he  gave  the  aI)ove 
name,  believing  that  tiiey  occurred  in  a  large  j)ercentage  of  kidneys  in  normal 
j)regnancv.  This  condition  is  sui)posed  t(^  exist  when  the  gravida  shows  edema  and 
albumimiria  in  the  latter  lialf  of  i)regnancv.  The  kidney  is  large,  pale,  soft,  cloudy, 
with  markings  obliterated,  anemic  or  grayish->'ellow  in  color,  and  microscopically 
shows  fatty  changes  in  the  glomeruli  and  tubules,  but  no  infiltration  of  leukocytes 
nor  vascular  changes. 

Slight  albuminuria,  a  moderate  number  of  hyaline  and  granular  casts,  with 
white  blood-corpuscles  and  renal  epithelium,  occur,  according  to  Fischer,  in  oO 
per  cent,  of  the  pregnancies,  but  in  the  author's  experience  such  findings  are 
always  indicative  of  some  compromise  of  the  function  of  tlie  kidnevs. 

In  the  author's  cases  albuminuria  is  always  regarded  with  great  suspici<jn, 
and  if  casts,  especially  granular  or  cellular,  appear,  the  woman  is  consi(l<'re<l  ill 
and  placed  under  treatment.  As  a  rule,  in  these  cases  edema,  la.ssitude,  hea<lache, 
and  neuralgia  accompany  the  urinary  findings.  The  author  consiilers  the  "kid- 
ney of  pregnancy"  only  the  iirst  evidence  of  a  mild  toxemia.  Often  the  symptoms 
become  aggravated — the  albuminuria  increases,  casts,  blood,  and  epithelium  ajjpear, 
the  urine  tliminishes  in  amount,  and  the  case  develops  the  characteristic  a.spect  of 
preeclamptic  toxemia.  Some  writers  call  these  aggravated  fimfings  the  "nephritis 
of  pregnancy,"  claiming  tliat  this  leads  to  eclampsia  or  to  coma.  Clinically,  it  is 
imj)ossible  to  ditYerentiate  these  cases  of  nephritic  t<jxemia  from  real  eclampsia, 
though  occasionally  one  may,  from  the  predominance  of  remd  symptoms,  susinrt 
that  most  of  the  trouble  lies  with  the  kidneys. 

With  our  present  views  the  "kidney  of  iiregnancy"  is  the  result  of  the  intoxica- 
tion of  i)regnancy,  and  the  causation  of  eclamjjsia  would  be  its  causation.  The  kid- 
neys sutYer  in  their  etYort  to  eliminate  toxins  or  undermetaboli/.ed  jjroduct.^  or 
insufficiently  oxidized  proteins  from  the  liver,  or  the  accumulated  excreta  of  the 
fetus.

nosis  from  the  urinary  findings.  In  nephritis  the  amount  of  albumin  may  be  less, 
with  lower  specific  gravity  and  less  coloring-matter.  Zweifcl's  sarcolactic  acid 
test  has  not  been  proved  clinically  useful,  and  the  nitrogen  partition  gives  equivocal 
results.  Since  the  condition  under  consideration  is  the  result  of  a  toxemia,  it  is  not 
surprising  that  pregnancy  is  frequently  interrupted  from  the  same  cause  (13  per 
cent..  Fellner).     The  kidney  of  pregnancy  may  recur. 

The  treatment  is  the  same  as  for  threatened  eclampsia. 

ACUTE  YELLOW  ATROPHY  OF  THE  LIVER 

Closely  allied  to  h^i^eremesis  and  to  eclampsia  is  acute  yellow  atrophy  of  the 
liver — the  icterus  gravis  of  older  writers.  Pregnancy  seems  to  predispose  to  this 
disease,  since  over  half  the  cases  reported  occur  in  pregnant  w^omen.  It  appears 
at  any  period  of  gestation,  during  labor,  or  in  the  puerperium.  Without  doubt 
several  diseases  may  terminate  under  the  clinical  picture  of  acute  yellow  atrophy, 
and  the  author  has  seen  hj-peremesis  gravidarum,  eclampsia,  sepsis  acuta,  and 
chloroform  poisoning  do  so,  also  one  case  of  secondary  sj^philis  in  a  prostitute. 
Other  authors  report  typhoid,  osteomyelitis,  diphtheria,  erysipelas,  phosphorus, 
alcohol,  and  ptomain-poisoning  as  precedent  illnesses.  It  is  sometimes  epidemic. 
The  causation  is  unknown,  and  whether  the  degeneration  of  the  liver  is  due  to  in- 
fection or  to  a  toxicosis  is  still  sub  judice.  Bacteria  (among  others  the  streptococcus, 
Prochaska)  and  Bacterium  coli  (the  author)  have  been  cultivated  from  the  liver, 
but  since  degeneration  and  not  inflammatory  changes  are  predominant,  the  theory 
of  an  intoxication  is  more  plausible. 

Pathology. — At  autopsy  the  liver  is  found  wasted,  perhaps  to  one-half  its 
volume,  soft,  friable,  sometimes  almost  diffluent,  yellowish  streaked,  and  mottled 
with  red.  Rarely  one  finds  an  acute  diffuse  hepatitis  or  the  evidences  of  other 
hepatic  disease,  in  which  case  the  liver  may  even  be  enlarged.  The  liver-cells  have 
undergone  albuminoid  degeneration,  the  nuclei  are  indistinct  or  absent,  and  in  the 
red  portions  the  cells  have  disappeared  entirelj^,  or  are  found  only  at  the  periphery  of 
the  lobules.  Tiny  hemorrhages  are  sometimes  found,  especially  under  the  capsule. 
The  interlobular  connective  tissue  appears  increased  because  the  liver-cells  have 
dropped  away  from  it  and  there  is  a  slight  wandering  in  of  leukocj'tes.  These  prob- 
ably have  to  do  with  the  conversion  and  the  carrying  away  of  the  fatty  degenerated 
parench^ana,  though  it  is  probable  that  a  proteolytic  enzyme  is  also  active.  The 
heart,  the  muscles,  and  the  glands  of  the  bronchi  and  of  the  digestive  tract  are  fatty 
degenerated,  and  all  the  tissues  are  bile  stained.  The  kidneys  are  intensely  in- 
volved, in  one  of  the  author's  cases  the  convoluted  tuliules  being  completely  de- 
generated, but  the  tubuli  recti  and  the  glomeruli  being  unafi'ected.  This  case  showed 
no  inflammatory^  changes,  but  such  are  reported  by  some  authors.  The  spleen 
is  large  and  soft,  similar  to  that  seen  in  the  acute  infectious  diseases. 

Symptoms. — ]\Iuch  variation  exists  in  the  descriptions  given  of  this  affection. 
If  the  hepatic  atrophy  is  a  termination  of  hj-peremesis  or  of  eclampsia,  the  symp- 
toms of  these  disorders  precede.  If  it  follows  the  use  of  chloroform,  the  symptoms 
are  very  acute — may  be  fatal  in  from  six  hours  to  as  many  days.  In  the  "idio- 
pathic" cases  a  prodromal  stage  with  anorexia,  vomiting,  constipation,  headache, 
perhaps  slight  mental  disturbances,  extreme  weakness,  a  tinge  of  icterus,  and  pain 
in  the  epigastrium  exists,  but  its  significance  is  not  recognized.  After  a  few  days 
to  a  few  weeks  symptoms  of  serious  illness  appear,  rarely  with  a  chill  and  high  fever 
(Vinay),  but  usually  suddenly.  Frequent  vomiting,  first  glairy,  then  bilious  and 
bloody,  anorexia,  thirst,  pain  in  the  epigastrium,  acholic  stools,  with  occasional 
hemorrhage,  intense  headache,  restlessness,  later  extreme  and  incessant  jactitation, 
wth  rolling  the  head  to  and  fro  on  the  pillow,  insomnia,  delirium,  sometimes  con- 
vulsions, and  coma  before  death.     In  secondary  chloroform  poisoning  I  have  seen

the  disease  end  fatally  in  six  hours  with  all  the-  characteristic  sj-mptoms  apix^aring 
in  rapid  succession.  AI)orti(jn  usually  takes  place  just  before  deatli,  l»ut  may 
not  occur.     Otherwise  uterine  hemorrhage  is  infre(juent. 

Examination  of  the  patient  shows  extreme  exaggeration  of  reflexes,  general 
icterus,  st^metimes  of  a  lemon,  .sometimes  of  an  orange-y<-llo\v,  tint;  minute  i)e- 
techia'  on  the  trunk  and  extremities,  or  an  erythematous  eruption;  a  slight  cyanosis 
of  the  face,  with  jiuffiness  of  the  features;  a  dry  brown  tongue,  with  S(jrdes;  a 
characteristic  but  indescribable  fa-tor  ex  on — it  resembles  the  fruity  odor  of  st-p.sis, 
but  has  a  slight  pungency;  the  pulse  is  fast,  weak,  and  numbers  120  to  140  l>eats; 
the  respirations  are  dyspneic,  stertorous,  and  later  weak  and  superficial;  the  t«-m- 
I)erature  is  almo.st  always  elevat<'d,— 102°  to  104°  F.,— but  is  rarely  subnormal; 
at  first  contracted,  later  dilated,  pupils  are  seen,  together  with  slight  exophthalmos; 
toward  the  end,  however,  the  eyes  are  sunken;  there  are  extreme  ti-ndernj-ss  over 
the  liver  and  diminution  of  liver  dulness,  which  is  determinable  by  daily  mea.sure- 
ment;  enlargement  of  the  spleen  occurs  (00  per  cent.);  the  urine  is  <liminished, 
containing  l)ile,  albumin,  casts  of  all  kinds,  fatty  renal  epithelium,  blood,  methe- 
moglobin  (Stumpf),  often  leucin  balls  and  tyrosin  crystals,  very  little  urea  (which, 
divided,  shows  a  large  percentage  of  annnonia  nitrogen,  indicating  that  the  liver 
function  is  in  abeyance),  acetone,  diacetic  acid,  indicaii,  albumose,  an<l  peptciue, 
but  sugar  rarely. 

One  or  more  of  these  .symptoms  or  findings  may  be  ab.sent,  but  always,  after 
the  i)rodromal  stage,  there  are  enough  present  to  make  a  positive  diagnosis.  The 
disease  lasts  a  few  hours  or  days  after  the  real  symptoms  appear,  the  most  raj)idly 
fatal  cases  l)eing  those  in  which  the  cereljral  symptoms,  delirium,  and  agitation  are 
worst.  Death  is  due  to  exhaustion  and  intoxication,  the  heart  giving  out  first,  and 
it  occurs  in  <leep  coma. 

Diagnosis. — If  a  pregnant  woman,  after  a  week  or  two  of  lassitude,  headache, 
and  sym])toms  of  gastric  catarrh,  suddenly  develojjs  delirium,  jactitation,  jaundice, 
with  epigastric  tenderness  and  diminution  of  liver  dulness,  the  diagnosis  of  acute 
yellow  atrophy  is  almost  certain.  If  such  .symptoms  appear  after  hN^peremesis, 
eclampsia,  and  sepsis,  the  diagnosis  may  still  be  asserted,  and  differentiation  is  not 
necessary,  since  both  may  be  due  to  the  same  cause,  which  may  be  unknown,  or  at 
least  its  action  not  understood.  The  administration  of  ciiloroform  should  be  con- 
sidered in  th(;  history  taking.  In  those  ca.ses  which  i)egin  with  a  chill  and  high 
fever  the  disease  may  be  an  acute  septicemia  with  this  unusual  clinical  picture. 
Confusion  will  ari.se  only  with  "Inlious"  typhoid,  yellow  fever,  and  phosphorus- 
poisoning,  but  a  can'ful  medical  examination  will  usually  pnjcure  clearness. 

Tiie  prognosis  is  bad.  Recoveries  are  report<'d,  and  while  most  authors  claim 
these  are  mistaken  diagnoses,  the  writer  believes  that  he  has  hatl  a  case  which  sur- 
vived the  disea.se.  The  fetus  is  practically  alwaj's  lost,  through  either  prematurity 
or  toxemia.  It  is  usually  icteric,  but  in  ca.ses  of  simple  maternal  icterus  the  child  is 
not  jaundiced. 

The  treatment  is  symptomatic.  In  hyperemesis  one  should  tenninate  preg- 
nancy as  soon  as  suspicions  are  aroused  that  the  liver  is  l)eginning  to  suffiT.  Indeed, 
in  all  cases  the  pregnancy  should  be  interrupted  as  soon  as  the  diagnosis  is  made, 
unless  the  patient  is  so  si<'k  that  the  interfen-nce  itself  would  jirecipitate  the  «'nd. 
Vaginal  cesarean  section  would  be  the  best  method. 


CHOPEA  GRAVIDARUM 
Another  disease  which  in  all  jirobaltility  is  toxemic  or  infectious  in  origin  is 
chorea  gravidarum.     The  causal  coimection  between  pregnancy  and  chorea  is  ver>' 
certain,   but  predisposition  is  provided  by  heredity  (neurasthenia,  insanity,  al- 
coholism, hysteria).  pre\'ious  chorea  in  infancy,   nervous  shock,  as  fear,   anger, 


372      THE  PATHOLOGY  OF  PREGNANCY,  L.\BOR,  AND  THE  PUERPERIUM 

acute  polyarticular  rheumatism,  endocarditis,  infections  of  various  kinds.  In 
three  cases  observed  bj'  the  author  the  ])icture  was  one  of  toxemia,  and  in  two  of 
them  treatment  on  this  hypothesis  resulted  happily.  In  milder  cases  a  hysteric 
element  may  be  discerned;  indeed,  some  authors  distinguish  a  hysteric  and  an 
idiopathic  form. 

Chorea  during  pregnancy  often  becomes  threatening,  the  movements  at  first 
locahzed,  rapidly  becoming  general,  incessant,  violent,  and  preventing  sleep.  One 
observes  anemia,  exhaustion,  delirium,  perhaps  maniacal,  and  later  torpor,  then 
fever,  coma,  and  death.  Emaciation,  bed-sores,  furunculosis,  cardiac  murmurs, 
and  albuminuria  are  som(^timt>s  found  on  examination.  All  degrees  of  severity  are 
noted.  The  disease  usually  appears  before  the  middle  of  pregnancy,  rarely  in 
labor,  and  still  more  seldom  after;  it  lasts  from  eight  days  to  months,  disappearing, 
as  a  rule,  ^^'ith  the  expulsion  of  the  ovum,  whether  spontaneous  or  induced.  Re- 
covery often  occurs  before  term,  delivery  then  being  natural.  The  child  may  be 
choreic.  The  toxemic  forms  are  acuter  and  seldom  go  to  full  term,  abortion  being 
common.  Primiparae  are  most  affected,  especially  if  younger  than  twenty-five 
years,  but  when  chorea  appears  in  a  multipara  or  recurs  in  a  subsequent  pregnancy, 
it  is  usually  more  serious. 

Tlie  prognosis  is  grave,  20  to  30  per  cent,  of  the  women  and  over  half  of  the 
children  dying,  the  latter  from  prematurit3\  Permanent  mental  disturbances  may 
follow,  as  after  eclampsia.  Death  occurs  from  exhaustion,  inanition,  injury,  de- 
cubitus, sepsis,  endocarditis,  and  toxemia,  shown  by  delirium  and  coma. 

Treatment. — The  general  rules  for  medical  cases  apply  here,  but  in  view  of  the 
danger  of  the  disease  and  its  prol^al^le  cause  (toxemia),  one  should  not  temporize 
too  long,  but  as  soon  as  the  movements  become  marked  the  patient  is  to  be  put  in 
bed  and  placed  on  a  milk-and-water  diet.  Sodium  bromid,  chloral,  even  morphin, 
may  be  administered,  but  the  author  was  able  only  with  hyoscin  to  calm  the  move- 
ments, and  even  this  failed  after  a  few  days.  By  skilful  nursing  the  nutrition  is 
maintained  and  exhaustion  prevented. 

Pregnancy  must  be  terminated  when  it  is  seen  that  the  general  health  has  begun 
to  suffer,  certainly  before  fever  or  delirium  begins.  Curiously,  Wade  saw  recovery 
after  dilatation  of  the  cervix  without  abortion,  as  Copeman  did  in  hyperemesis. 
If  the  uterus  is  emptied  early  enough,  recovery  is  the  rule. 


PRESUMABLE  TOXEMIAS 

Every  physician  meets  conditions  in  pregnancy  which  are  best  explained  by 
calling  them  toxicoses.  Truly  the  expression  means  nothing  definite,  but  the  affec- 
tions present  the  picture  of  intoxications  and  respond  to  appropriate  treatment. 
Asthma  in  a  woman  who  never  had  the  disease  before  may  have  such  a  basis.  Faint- 
ing spells,  acute  collapse,  or  even  sudden  death  may  have  no  other  apparent  cause. 
Such  accidents  strongly  reseml:)le  anaphylactic  phenomena.  Peripheral  neuritis 
may  be  of  septic  origin,  but  well-authenticated  cases  have  been  found  as  a  comph- 
cation  of  an  almost  certain  toxemia, — h^^^peremesis  gravidarum, — as  in  the  case  of 
Soloview,  quoted  by  Vinay.  The  tingling  of  the  hands  and  legs,  with  numbness, 
even  anesthesia  and  paresis,  of  which  many  pregnant  women  complain,  are  ])rol)- 
ably  due  to  affection  of  the  nerves  by  some  circulating  toxin.  The  nerve-trunks 
are  tender  and  sometimes  determinably  enlarged,  especially  the  ulnar.  Since  th( 
symptoms  disappear  quickly  after  dehvery,  the  injury  to  the  nerves  is  sHght,  but 
grave  forms  of  neuritis  and  polyncniritis  do  occur,  either  on  a  toxemic  or  an  infec- 
tious ])asis. 

Psychoses  during  pregnancy  are  usually  toxemic.  A  ])ad  heredity  is  found 
in  nearly  half  of  the  cases,  but  this  does  not  preclude  the  idea  of  a  toxicosis,  because 
we  have  seen  that  such  taint   predisposes  to  other  toxemias,  as  eclampsia  and 


PSYCHOSES    IN    PREGNANCY  373 

hyperempsis.  It  seems  that  disturbed  metabolism  is  more  common  in  women  whose 
nervous  systems  are  not  v(\un[  to  the  strain  lA  pref^nancy.  The  author,  in  tw(j 
instances  of  insanity  in  prej^nancy,  produced  striking  results  with  eliminative  treat- 
ment, thou}i;h  in  one  mental  disease  developed  after  an  afei)rile  puerjK'rium  of  eight 
weeks.  Korsakoff's  psychosis  has  been  observed  in  j)regnancv.  While  usually 
alcoholic  in  origin,  the  syndrome,  polyneuritis  and  ddusictns,  may  apjK-ar  during 
the  early  months  of  gestati(jn,  and  a  toxemia  may  be  inv<jlvcd.  \\'illiams  and  (jthers 
believe  that  most  cases  of  puerj)eral  insanity  are  infectious  in  (origin.  The  fre- 
quency of  insanity  after  puerperal  fevers  is  strongly  suggestive,  but  very  often  the 
psychosis  follows  an  eclami)sia,  a  chorea,  hyiwremesis,  or  a  normal  puerjierium.  and 
other  theories  must  be  inv<jked.  One  might  divide  the  cases  into  infectious,  toxic, 
and  idiopathic  (heredity,  inaniti<jn,  anemic)  p.sycho.'^es.  It  is  more  than  possible 
that  some  of  the  diseases  we  call  toxemias  are  in  reality  infections,  the  causal  bac- 
terium still  ehuling  our  crude  methods  of  investigati<jn. 

Most  authors  do  not  favor  the  induction  of  abortion  or  premature  labor  in  the 
insanity  of  pregnancy,  but  the  writer  believes  that  the  cases  slnjuld  be  treated  just 
as  any  other  toxemia,  unless  the  accoucheur,  after  consultation  with  an  alienist,  is 
convinced  that  the  mental  disease  is  simply  contemporaneous  with  gestation,  with- 
out direct  causal  relation.  So  far  as  the  child  is  concerned,  no  indication  for  abor- 
tion will  lie,  Ix'cause  if  the  psychosis  is  toxemic,  the  condition  is  not  necessarily 
transmitted  to  the  offspring,  and,  further,  we  have  no  right  to  sacrihce  the  child 
on  the  assumption  of  the  possibility  of  its  being  mentally  unfit. 

In  some  neurotic  women  I  have  .seen  the  occurrence  of  pregnancy  produce  a 
degree  of  terror  that  certainly  wa.s  close  to  mania.  During  labor  acute  insanity  is 
sometimes  ob.servetl  in  women  of  poor  nervous  balance,  neuropaths,  hysterics,  when 
the  pain  is  very  severe.  Without  doubt  the  strain  of  labor  is  too  much  for  many 
nervous  systems,  and  the  author  believes  that  prolonged  painful  labor,  without  in- 
fection, will  explain  many  cases  of  puerperal  insanity.  Transitory  mental  aberra- 
tion during  the  agony  of  the  second  stage  is  not  .-seldom  observed,  and  it  njay  l>e 
infanticidal  or  homicidal,  a  point  of  importance  in  medicolegal  cases.  It  is  an 
indication  for  immediate  delivery. 

During  the  puerperium  and  lactation  insanity  is  a  not  infrequent  di.'iea.'^e, 
statistics  of  the  asylums  showing  from  10  to  18  per  cent,  of  female  inmates  affected 
at  this  time.  Puerperal  infection,  mastitis,  eclampsia  and  allied  toxemias.  ix)st- 
partum  and  other  hemorrhages,  especially  if  grafted  on  a  batl  heredity,  exhausting 
lal)or,  the  drain  of  lactation,  are  the  most  common  causes.  The  attack  may  be 
developi'd  by  a  violent  psychic  .^hock,  such  as  death  of  husband  or  chiltl. 

Melancholia  witii  suicidal  intent  was  the  most  common  form  in  the  author's 
cases,  but  mania  with  infanticidal  tendencies  was  also  observi-d.  \'inay  says  that 
the  maniacal  forms  are  most  frequent.  The  prognosis  is  fair,  the  majority  of  the 
cases  recovering  in  from  six  weeks  to  six  months.  The  treatment  is  along  general 
lines. 

Neuritis. — Pain  in  the  nerves,  especially  the  trigeminal,  the  ulnar,  and  the 
sciatic,  is  I'rcciuently  noted  in  jiregnancy,  and  is  generally  treated  as  a  neuralgia, 
but  often  prickling  .sensations,  numbness,  and  slight  paralysis  of  the  meml)er  or 
members  show  that  the  nerve  is  more  ileeply  involved — that  a  neuritis  exists.  Poly- 
neuritis with  marked  jxiralyses,  even  atrojihy,  has  been  ob.-^erved.  and  has  l)een 
ascribed  to  toxemia.  The  degeneration  of  special  nerves  in  hyix-remesis  gravidarum 
has  been  mentioned.  Not  rarely  jiregnant  women  comjilain  of  nund>ne."<s  and 
pricking  of  the  fingers,  with  lack  of  i)ower  in  the  hands,  and  examination  shows  the 
members  to  be  puffy,  slightly  cyanosed.  with  diminished  tactile  sensibility,  and 
occasionally  tenclerness  of  the  ulnar  nerve  is  discovered.  The  nerves  of  the  sjxH-ial 
senses  may  be  involved— neuritis  optica,  auditoria.  etc.  {q.  v.),  and  the  pregnancy 
may  have  to  be  terminated  to  prevent  perman«nit  blinilness  or  <lo.afn.ss.     After

delivery  the  symptoms  rai)i(lly  subside,  having  l)een  pr()l)al)ly  toxemic.  Treat- 
ment is  along  these  lines. 

Puerperal  neuritis  is  of  the  same  nature,  though  Bar  calls  it  septic.  Mono- 
plegias after  delivery  are  probably  septic.  They  are  usually  radial  or  culwtal, 
Mobius  believing  that  these  nerves  are  points  of  predilection  in  puerperal  infections. 
Sciatic  neuritis  is  particularly  intense  when  a  puerpera  is  affected.  Occasionally 
paralysis  and  atrojihy  r(>sult.  While  some  of  the  cases  are  acute  and  heal  rapidly, 
many  pursue  a  course  of  months,  and  recovery  may  be  incomplete.  When  the  con- 
nective tissue  of  the  pelvis  is  inflamed,  the  nerves  of  the  sacral  plexus  not  seldom 
are  also  involved,  with  peripheral  muscular  and  sensory  disturbances.  Recovery 
occurs  after  the  infiammatorj^  process  has  sul)sided,  ])ut  scar  formation  may  render 
it  incomplete. 

Injury  to  the  nerves  in  the  pelvis  by  the  forceps  may  result  in  peripheral  neu- 
ritis or  paralysis,  but  the  prognosis  is  good.  The  differential  diagnosis  is  on  general 
lines — here  need  only  be  mentioned  the  rupture  of  the  symphysis  pubis,  where  the 
pseudoparaplegia,  with  abduction  of  the  thighs,  at  first  glance,  might  cause  con- 
fusion. The  findings  over  the  pubis  and  the  results  of  the  neurologic  examination 
will  always  clear  the  cUagnosis.  Treatment  of  neuritis  is  given  in  text-books  on 
internal  medicine.  For  toxemic  polyneuritis  it  may  be  necessary  to  induce  labor, 
especially  if  vital  nerves — phrenic,  pneumogastric,  or  the  nerves  of  the  special 
senses — begin  to  show  the  least  involvement. 


BLOOD  DISEASES 

Older  writers  spoke  of  the  condition  of  the  blood  during  pregnancy  as  being  one  of  chlor- 
anemia.  Later  studies  show  that  in  healthy  women,  rather,  there  is  an  increase  of  the  reds,  of  the 
hemoglobin,  of  the  fibrin,  and  of  the  white  blood-corpuscles.  Anemia  in  the  early  months,  how- 
ever, is  not  uncommon,  especially  if  the  woman  was  chlorotic  as  a  girl.  It  is  probable  that  the 
fetus  obtains  its  iron  from  the  maternal  red  blood-corpuscles,  and  this  maj^  explain  the  anemia  of 
the  early  months,  the  blood-forming  organs  not  being  equal  to  their  added  tasks.  The  author 
frequently  gives  iron,  arsenic,  and  mercury  in  combination  during  pregnancy,  wdth  success  in 
anemic  states.  Chlorosis  is  a  not  infrequent  cause  of  abortion  which  tonic  treatment  may  pre- 
vent. Chlorotic  women  stand  hemorrhage  very  poorly,  a  loss  which  may  be  insignificant  for 
another  being  fatal  to  them,  and,  besides,  they  show  a  tendency  to  bleed — a  point  of  great  im- 
portance in  the  treatment  of  the  third  stage.  Chlorosis,  wliich  is  often  a  sign  of  general  infantil- 
ism, may  cause  atonia  uteri  during  the  second  and  third  stages  of  labor,  and  one  may  find  a 
generally  contracted  pelvis  too. 

Pernicious  anemia  seems  to  be  favored  by  frequent  child-bearing,  especialh'  if  the  woman 
is  otherwise  weak  or  anemic.  Hemorrhage  favors  the  disease,  and  it  may  follow  an  infection; 
indeed,  a  careful  diagnosis  is  necessary  to  shut  out  tuberculosis,  cancer,  helminthiasis,  chronic 
gastritis,  intestinal  infections,  and  other  conditions  which  cause  secondary  anemia.  A  toxemia 
would  cause  the  disease,  but,  although  this  theory  has  been  advanced,  no  proof  is  shown.  The 
same  causes  are  said  to  excite  leukemia  wliich  may  occur  during  pregnane}',  but  it  is  doubtful 
if  there  is  any  special  relation  between  the  two.  If  there  were,  one  should  meet  the  disease  oftener. 
The  prognosis  is  bad  in  both  these  affections,  and  the  pregnancy  should  be  terminated  as  soon  as 
the  diagnosis  is  made,  though  often  neither  child  nor  mother  is  much  benefited  by  the  interference. 

Labor  may  occur  naturally  in  these  conditions  without  any  particular  tendency  to  hemor- 
rhage, but  sudden  exhaustion,  with  coma  and  a'dema  pulmonum,  has  been  frequently  noted  to 
follow  a  few  hours  after  delivery.     Ijcukemia  does  not  pass  over  to  the  fetus. 

Hemophilia  is  rare  during  the  reproductive  period.  Contrary  to  most  writers,  the  author 
believes  that  fatal  cases  of  hemophilia  can  occur  during  delivery.  Hemophiliacs  may  have  profuse 
menses,  and  may  bleed  to  death  from  defloration;  they  abort  fre(|ucntly,  and  may  have  post- 
partum hemorrhage  or  late  bleedings  in  the  puerperium.  Hemophilia,  or  at  least  a  hemorrhagic 
diathesis,  can  occur  in  a  woman  who  has  no  family  history  of  it,  and  in  whom  the  bleeding  tendency 
has  not  been  in  evidence  in  previous  deliveries,  abortions,  or  menstruations.  The  author  is  con- 
vinced that  a  temporary  hemorrhagic  diathesis  can  occur  during  pregnancy,  its  basis  being  a  la- 
tent hemophiha,  syphilis,  malaria,  intoxication  by  chemical  or  hemolytic  poisons,  a  toxemia,  or  a 
sep.sis.  It  is  a  generally  admitted  fact  that  toxemia  disposes  to  hemorrhage.  The  hemorrhagic 
types  of  eclampsia,  hyperemesis,  etc.,  are  particularly  fatal.  The  blood  in  the  cases  observed  by 
the  writer  was  lake-colored,  like  port  wine,  the  clots  small,  soft,  and  black.  Suggillations,  pe- 
techia;, and  bloody  infiltration  around  the  vulva,  vagina,  and  cervix  and  the  hypodermic  punctures 
betrayed  the  fact  of  a  dissolution  of  the  blood. 

In  one  case  of  ha;matoma  vulva;  (p.  743)  the  woman  had  a  gingivitis  with  hemorrhages  and 
other  toxemic  symptoms  which  gave  almost  the  clinical  picture  of  scurvy.  It  is  more  than  possible 
that  a  toxemia  or  infection  lies  at  the  bottom  of  these  diseases.  This  subject  is  an  inviting  field 
for  investigation. 


BLOOD    DISEASES    IN    PREGNANCY  375 

So  far  as  treatment  is  concerned,  if  the  condition  is  recoKnizc*!  during  pregnancy,  the  attempt 
should  be  made,  by  general  tonic  remedies,  to  upbuild  the  patient's  slrennth.  Iron,  mercur>', 
and  arsenic  have  given  the  author  good  results.  Calcium  chlorid  and  gelatin  are  supik^hhI  to 
increase;  the  clotting  power  of  the  blood,  ami  may  be  ailministere<|  for  a  few  days  Ix-fore,  during, 
and  after  labor.  The  author  could  not  convince  himself  that  any  effect  wa.s  obtained,  a  view  also 
held  by  Holiertsoii.  The  use  of  a  heterogene<jus  serum,  as  that  of  the  h(»rs<',  has  Ixn-n  advocatetl 
in  cases  of  obstinate  hemorrhage,  as  al.so  luis  been  human  wrum,  and  the  results  with  the  latt<T 
certainly  enc(nirage  trial.  TIk;  object  is  to  supply  the  mis.sing  thrombin,  thromlxjgen,  and 
thrombokina.se. 

TIh- author  has  had  two  ca.ses  of  polyglobulism,  a  syndrome  with  enlarged  spleen,  intense 
cyanosis,  hypererjMhrocytosis.  The  spleens  in  both  patients  reache<l  the  brim  of  the  pelvis;  one 
woman  had  .S,()1M),()()0  reds  and  (><),()()<)  whites,  clubbed  hngers,  rheimiatic  pains,  anc!  general  as- 
thenia. One  was  sterile  after  having  had  two  children  before  the  flisexs*'  aiJiwared;  one  had  two 
still-born  macerated  children,  then,  imder  iron,  arsenic,  an<l  mercury  treatment,  a  live  child  with- 
out trouble,  followed  by  sterility.  Tiie  pregnancy  seemed  to  aggravate  the  general  conditions  very 
nmch. 

SKIN  DISEASES  IN  PREGNANCY 

A  close  relation  e.xists  Ix'tween  the  skin  and  the  ehanK<'s  in  the  general  metab- 
olism clue  to  pregnancy.  Virciiow  antl  Xeu.s.ser  believed  that  there  is  some  relati<jn 
between  the  ovaries  and  the  skin.  Of  the  milder  manifestations  of  the  disturl)ed 
nutrition  of  the  intcKument  may  be  mentioned  tlie  pigmentation,  hy]><'ridrosis, 
edema,  falling  of  the  hair,  cracking  of  tiie  nails,  erythema,  acne,  etc.  While  most 
skin  diseases  are  aggravated  or  even  developed,  some  are  cured  by  the  advent  of 
pregnancy.  Pregnant  women  may  have  all  the  dermatoses  that  other  women  liave, 
and,  since  the  reaction  is  usually  more  severe,  it  is  probable  that  many  of  the  affec- 
tions hitherto  designated  as  gestational  are  really  merely  coincident.  The  latest 
and  most  complete  exposition  of  the  subject  is  given  by  Scheuer. 

Pruritus  is  an  affection,  perhaps  neurotic,  perhaps  toxemic,  u.sually  localized 
on  tiie  vulva,  .sometimes  general,  which  begins  in  the  middle  or  end  of  pregnancy,  and 
may  rarely  reach  such  an  intensity  as  to  demand  the  emptying  of  the  uterus.  Dia- 
betes should  always  be  looked  for.  Xi^urastiienic  and  hysteric  wom<'n  more  often 
have  the  itciiing.  (lenital  i)ruritus  is  often  a  .><ymptom  of  varicose  veins,  edema, 
vulvitis,  vaginitis,  cervicitis,  with  leukorrheal  discharge,  and  in  the.se  ca.ses  the  skin 
of  the  vulva  is  thickened,  red,  and  shiny.  Mycosis  vulvie  is  not  infrequent  in 
multipane.  Lack  of  cleanliness  is  another  cau.se  of  itching.  I^czema  and  other 
dermatoses  must,  of  course,  l)e  .nought.  The  pruritus  is  usually  worse  at  night  and 
in  summer  becau.se  of  the  warmth,  and  the  patients  lose  sleep.  After  delivery  re- 
covery promptly  ensues.  Subsequent  pregnancy  usually  shows  recurrence.  In  one 
ca.se  the  author  found  evidences  of  renal  inefficiency,  and  the  woman  had  a  i^rurigi- 
noid  eruption  on  the  arms,  legs,  back,  siioulders,  and  chest.  Bcsnier  called  this 
form  of  prurittis  "prurigo  gestationis."  He  describes  an  itchy  eruption  of  tiny  jiajv 
ules  closely  grouped,  especially  on  the  l)acks  of  hands  and  feet.  ai)iK'aring  usually 
after  the  third  month,  recurring  in  successive  pregnancies,  and  disapiM-aring  after 
delivery.  Usually  the  skin  is  normal  in  aj)i)earance  except  for  scratch-marks.  The 
treatment  is  general  and  local.  If  iliabetic,  the  usual  treatment;  if  to.xemic  or 
neurotic,  appropriate  remedies  will  l)e  employed.  Sodium  bromid  in  2t)-grain  doses 
often  produces  sleep.  A  bland  diet,  without  condiments,  spices,  ami  alcoholics, 
and  one  with  little  protein, is  i)rescribed— in  short, general  hygienic  conduct.  Baths 
may  be  tried,  but  the  author  has  iiad  little  success  with  tluMii.  Very  light  clothing, 
with  linen  next  to  the  skin,  is  good.  For  local  use  on  the  skin  the  author  Iv^  had 
success  with  this  lotion:

For  pruritus  vidvie  the  author  has  u.^ed  with  varying  success  the  following 
applications:  Chloral  hydrate,  o  to  20  gm.  per  liter;   bichlorid  of  mercury,  1  :  1000; 


376      THE  PATHOLOGY  OF  PREGNANCY,  LABOR,  AND  THE  PUERPERIUM 

carbolic  acid,  2  per  cent,  solution;  essence  of  peppermint,  4  gm.  per  liter;  an  oint- 
ment consisting  of  ichthyol,  2  per  cent.;  menthol,  0.5  per  cent.;  ointment  of  rose- 
water,  a  sufficient  quantity;  or,  carbolic  acid,  0.5  per  cent.;  menthol,  1  per  cent.; 
zinc-oxid  ointment  and  ointment  of  rose-water,  of  each,  a  sufficient  quantity. 

The  washes  and  ointments  are  to  be  applied  cold,  after  cleansing  the  parts 
thoroughly  with  tar-soap  and  water,  using  much  soap.  In  cases  of  mycosis  vulvae 
the  white  patches  are  to  be  painted  with  10  per  cent,  silver  nitrate,  and  the  patient 
given  a  dusting-powder  of  boric  acid.  This  smarts  a  good  deal,  ])ut  is  helpful. 
For  irritating  discharges  the  best  results  have  been  obtained  with  daily  potassium 
permanganate  douches,  1  :  3000,  followed  b}'  one  of  essence  of  peppermint,  a  tea- 
spoonful  to  a  quart  of  cool  water. 

Excessive  pigmentation  cannot  be  combated  during  gestation.  If  the  mask  of 
pregnancy  does  not  disappear  within  six  months  after  delivery,  the  parts  may  be 
rubbed  wdth  pure  lemon-juice  morning  and  evening,  which,  failing  to  remove  the 
stains,  a  treatment  with  bichlorid  of  mercury  may  be  recommended,  under  the  care 
of  a  good  dermatologist. 

Excessive  hirsuties,  very  rare  in  pregnane}',  usually  disappears  of  itself. 

Brickner  describes  a  disease  which  he  calls  fibroma  molluscum  gravidarum. 
The  forehead,  chest,  shoulders,  arms,  and  hands,  in  the  order  named,  present  pedun- 
culate, pinkish,  warty  excrescences,  in  size  from  a  pin-head  to  a  bean,  which  drop 
off  before  or  surely  after  labor,  A  tendency  to  warts  is  known  to  exist  in  preg- 
nancy, but  no  one  has  described  this  disease.  The  writer  has  seen  five  cases  of  it, 
but  in  none  was  the  eruption  so  generalized  as  in  Brickner's.  Treatment  is  symp- 
tomatic. 

Edema. — ]\Iore  than  half  of  all  pregnant  women  show  some  edema  of  the  feet, 
the  hands,  or  the  face.  Often  this  is  an  elastic  puffiness  which  does  not  pit.  The 
cause  of  this  is  not  known.  A  real  anasarca,  with  exudation  of  serum  in  the  tissues, 
is  usually  due  to  toxemia,  renal  or  hepatic,  and  is  produced  by  the  alteration  of  the 
constitution  of  the  blood  or  capillaries  or  both.  It  is  present  in  the  morning  in 
the  feet,  hands,  and  eyelids,  sometimes  disappearing  by  night. 

Edema  which  grows  worse  during  the  day  is  usually  due  to  mechanical  causes 
— varicose  veins,  tight  garters,  cardiac  disease,  and  obstruction  to  the  abdomi- 
nal circulation  (twin  pregnancy,  pendulous  belly,  abdominal  constriction).  The 
accoucheur  is  warned  not  to  conclude  lightly  that  an  edema  is  mechanical  or  of  no 
significance  because  the  urinary  findings  are  negative.  A  nephritis  may  exist 
without  albuminuria,  and  eclampsia  may  occur  with  no  other  warning  than  the 
anasarca. 

The  treatment  is  plain  when  the  cause  is  discovered.  General  obstetric  hy- 
giene usually  suflaces.  (See  p.  225,  The  Conduct  of  Pregnancy.)  It  has  been  sug- 
gested that  the  amount  of  salt  in  the  food  be  curtailed,  but  the  author  has  not  seen 
constant  improvement  under  this  regimen.  Rest  in  bed  with  milk-and-water  diet 
is  one  of  the  best  means  we  have.  Excessive  edema  is  always  pathologic,  and  usu- 
ally preeclamptic,  and,  therefore,  treatment  directed  against  the  toxemia  is  indi- 
cated. Puncture  of  the  swollen  tissues  should  not  be  done  unless  the  patient  is  in 
labor  and  soon  to  be  delivered,  because  of  the  danger  of  infection  from  the  prolonged 
drainage  and,  of  course,  extreme  antisepsis  will  be  observed. 

Special  skin  diseases,  described  by  writers  as  due  to  pregnancj^  are  very  rare. 
Herpes  gestationis  is  a  form  of  herpes  which  appears  during  pregnancy,  especially  on 
the  arms,  legs,  face,  and  chest,  in  the  order  named,  passes  through  the  usual  states 
of  grouped  vesicles,  small  bullae,  pustules,  and  crusts — is  of  chronic  nature,  and 
liable  to  recurrence  in  subsequent  pregnancies.  Very  probably  other  affections, 
for  example,  erythema  multiforme  and  dermatitis  herptj^ormis,  have  been  called 
herpes  gestationis.  'P 

Impetigo  herpetiformis  (Hebra),  on  the  other  hand,'*is  a  serious  disease  (mor-

tality,  so  per  cent.),  sufficiently  cliaracteristic  to  l»e  called  a  gestational  affection, 
thouf^h  it  is  rare  in  America.  The  following  is  a  (le.scrii)tion  of  the  autlior's  typical 
caae  treated  in  conjunction  with  Dr.  Josef  Zeisler: 

A  quinfipiira,  iifiod  thirty-.st'vcii,  hiwi  the  iliscasc  in  Ikt  third  |»r(>:naii<-y  and  niiwarric*!.  hut

eral weakness,  voinitinn,  diarrhea,  instininia,  pain  in  the  lejjs,  and  an  eruption  wliieli  Ix-gan  on  the 
inside  of  the  tliijihs  and  has  sh)\vly  spread  all  over  the  legs,  trunk,  ami  arm.-*.  (•rou|>s  of  pustul<t«,

genital  region  the  crusts  an<l  excoriated  skin  proiluced  a  n<l,  fetid,  oo/ing,  Lkt-ding  surface.  The 
mouth  was  early  .iffectel,  showing  gray  j)la(|in  s. 

The  general  condition  of  the  woman  is  po(»r,  hut  she  has  no  fever, —  contrarj'  to  Kaposi, — a 
pulse  of  ahout  KM),  and  there  i.s  slight  icterus.  At  eight  months  the  woman  al>orle<l,  whereuixm  the 
eruption  rapidly  ilisappeared  and  lln'  woman  c|uickly  rec<»vercd.  Tlie  cliild  hhowed  no  eruption. 
Hacteriologic  examination  of  the  jiustules  and  of  the  hlood  was  negative.  I'olyuria  was  pn-s<*nt, 
with  a  trace  of  alhumin,  diminished  urea,  no  sugar,  no  j)ei)tones  or  indicaii,  and  no  casts. 

The  cause  of  impetigo  herpetiformis  is  unknown-  an  infection  or  a  toxemia  ap- 
pears pr()l)able.  Wolff-Eisner  believe  it  is  of  an  anaphylactic  nature,  the  foreign 
protein  coming  from  the  uterus.  Mayer  believes  it  is  a  toxemia,  anil  that  the 
system  does  not  react  with  sufficient  antitoxin.  He  therefore  injected  20  c.c.  of 
the  blood-serum  of  a  healthy  graviila  to  supply  the  antitoxin.  Result,  cure  in  three 
cases.  Treatment  is  palliative,  but  the  author,  having  ol).served  the  rapid  subsi- 
dence of  the  disease  following  the  expulsion  of  the  fetus,  if  rapid  amelioration  did  not 
follow  Mayer's  treatment,  would  induce  labor. 

During  the  puerperium  the  author  has  obsers'ed  the  following  skin  diseases: 
Sudamina;  acne;  furunculosis;  erythema  multifonne;  pityriasis  versicolor;  drug 
erui:)tions;  urticaria  from  too  free  use  of  cresylic  acid  preparations;  eczema  from 
bichlorid.  which  in  one  ca.se  l)ecaine  a  generalized  eruption  with  high  fever,  and  was 
erroneously  called  by  the  attending  physician  an  erysipelas.  Septic  eruptions  will 
be  discussed  under  Puerperal  Infections.

CHAPTER  XXIX 
LOCAL  DISEASES  INCIDENT  TO  PREGNANCY 

Varicosities. — \'arices  of  the  logs  or  of  the  vulva  or  hemorrhoids  are  found  in  a 
majority  of  pregnant  women.  While  marked  varicosities  are  present  in  only  20 
per  cent,  of  gravidiB,  a  few  dilated  veins  are  an  almost  constant  accompaniment  of 
gestation.  The  veins  of  the  ankles,  legs,  thighs,  vulva,  vagina,  rectum,  and  broad 
ligaments  are  affected,  in  frequency  and  degree,  according  to  the  order  given,  but 
one  or  the  other  form  may  be  alone  present  or  predominant.  Fine  venous  networks 
or  large  paquets  of  tortuous  veins,  resembling  bunches  of  angle-worms,  are  observed. 
The  vulvar  hps  may  be  enlarged  and  spongy  (Fig.  132).  They  resemble  varicoceles 
and  cause  much  the  same  distress.  Edema  often  attends  varicosities.  The  patient 
complains  of  pain,  fatigue,  burning,  itching,  and  a  feeling  of  tension  in  the  affected 
parts.  In  some  cases  the  veins  are  so  dilated  and  the  legs  so  edematous  and  painful 
that  the  patient  can  hardly  walk.  After  the  deliver}^  of  the  child  the  varicosities 
collapse,  and  they  almost  always  disappear  in  three  weeks.  The  causes  of  varicose 
veins  are  not  knoAvn,  but  pregnancy  surely  has  much  to  do  with  developing  them. 
Women  who  are  much  on  their  feet  and  have  to  work  hard,  multiparse  with  pendu- 
lous belly,  women  with  heart  disease,  are  most  afflicted,  and  a  special  disposition 
can  also  be  observed.  This  may  be  congenital.  Frequent  pregnancies  and  tight 
abdominal  bands  and  garters  also  favor  them.  Varicosities  are  not  due  to  pressure 
of  the  gravid  uterus  on  the  veins  of  the  pelvis,  because  this  is  impossible,  nor  to 
increased  intra-abdominal  tension,  because  this  seldom  exists  to  such  a  degree. 
That  there  is  some  obstruction  to  the  return  circulation  from  the  legs  is  highly 
probable,  but  there  must  be  some  change  in  the  vessel-wall  or  of  the  blood  which 
predisposes  to  venectasis  during  pregnancy.  Toxemia  again  has  been  suggested, 
also  a  vasodilating  ferment  from  the  corpus  luteum.  It  may  be  the  same  condition 
which  causes  the  pelvic  vessels  to  enlarge  and  dilate  with  the  progress  of  pregnancy. 
That  some  such  relation  exists  is  proved  by  the  fact  that  in  some  women  the  veins 
enlarge  as  soon  as  conception  occurs,  and  that  they  collapse  if  the  fetus  dies  in  utero. 
With  other  abdominal  tumors  varicose  veins  of  the  legs  are  rarely  observed,  and 
this  point  may  ])e  used  in  the  differential  diagnosis.  A  woman  w^as  sent  to  the 
author  from  a  neighboring  city  for  her  accouchement.  She  was  suffering  from 
carcinoma  of  the  ovaries  with  immense  abdominal  distention.  There  were  no 
varicosities,  but  the  patient  said  she  had  had  such  in  all  her  six  pregnancies. 

Varicosities,  beyond  the  pain  they  produce,  are  dangerous  because  they  may 
ulcerate,  become  infected  (phlebitis  and  periphlebitis),  may  thrombose,  sometimes 
give  rise  to  emboli,  and  may  burst,  allowing  fatal  hemorrhage.  Vaginal,  vulvar, 
and  broad-ligament  varices  may  rupture  also  into  the  connective  tissue,  causing 
hematomata,  which  may  be  fatal  from  internal  hemorrhage,  or,  becoming  infected, 
from  sepsis.  During  labor  vaginal  and  vulvar  varicosities  not  seldom  are  torn,  re- 
quiring quick  diagnosis  and  immediate  suture  or  firm  tamponade,  because  the  bleed- 
ing is  profuse.  Differential  diagnosis  from  placenta  prsevia,  abruptio  placentae, 
and  atony  of  the  uterus  must  be  made,  which  is  done  by  inspection  and  finding 
the  bleeding  vessel.  A  hematoma  occurring  during  labor  may  obstruct  the  de- 
livery of  the  fetus.  Treatment  consists  in  opening  and  packing  the  cavity  until 
the  cervix  is  dilated,  then  removal  of  the  jxicking,  delivery,  followed  l)y  repacking 
the  cavity  of  the  hematoma  and  the  uterovaginal  tract.     Occasionally  a  varix  of

Clotting,  occurring  in  broad-ligament  varices,  may  lead  to  cnd)oli,  which  may 
break  off  during  labor,  and  this  warns  to  gentleness  in  handling  the  uterus  during 
the  third  stage  or  during  the  pucrperium, 

Trvat>ncnt.—\  hemorrhage  from  a  varicosity  is  easily  controlled  by  pressure 
or  suture.  The  patient  must  be  instructed  to  avoid  injuring  and  infecting  the 
superficial  veins  by  scratching  them  or  knocking  against  things;  to  avoid  coitus  if 
the  varices  are  vulvar  or  vaginal,  and  she  should  be  taught  how  to  st(jp  hemorrhage 
while  waiting  for  help  if  one  of  them  shoukl  bleed.  Phlebitis  and  periphlebitis 
are  treated  by  rest  in  bed,  moderate  elevation  of  tlie  leg,  and  wet  boric-acitl  drcKs- 
ings.  Rest  must  be  enjoined  for  three  weeks,  or  until  it  is  judged  that  the  throm- 
bosis is  complete  and  the  thrombus  firndy  organized -this  to  avoid  the  danger  of 
embolism,  Supi)urating  thrombi  of  the  legs  ar(>  to  be  drained.  Little  can  be  done 
to  improve  the  bad  cases  of  varicosities  during  pregnancy.  A  rubber  stocking  or 
flannel  bandage  may  be  worn,  and  the  feet  held  elevated  whenever  possible,  ^iore 
comfort  is  gotten  from  the  api)lication  of  adhesive  .-strips  ])laced  spirally  around  the 
limbs  while  the  woman  is  recumbent.  They  divide  and  support  the  coluiim  of 
blood. 

Hemorrhoids  occasionally  are  very  obstinate  and  annoying  to  the  pregnant 
woman,  who  perhaps  is  not  alTected  with  them  under  other  conditions.  Hemor- 
rhages, fissures,  with  exuberant  granulations,  or  extrusion  and  gangrene,  may  occur. 
Operation  is  not  to  be  made  during  gestation,  but  the  usual  treatment  may  be  pur- 
sued. During  labor  the  hemorrhoids  come  out,  swell  up,  and  may  bleed.  They 
predispose  to  lacerations  of  the  perineum.  An  attempt  should  be  made  to  replace 
and  retain  them  with  a  pad.  Some  accoucheurs  use  this  opportunity  to  remove  the 
masses,  but  pnjljably  it  is  best  to  wait  until  the  jiueriierium  is  over.  Postj)artum, 
hemorrhoids  often  cause  a  great  deal  of  distress.  If  the  piles  are  internal,  they  may 
be  replacetl,  under  ether  if  necessary;  if  external,  no  such  attempt  may  be  made, 
but  the  hips  should  be  elevated  and  cold  applied  to  the  parts.  If  there  is  a  hemor- 
rhage into  one  or  the  other  pile,  it  may  be  incised  under  local  anesthesia  and  the 
clot  turned  out.

Relaxation  of  the  Pelvic  Joints. — The  ancients  believed  tiiat  the  pelvic  l)ones 
separated  during  delivery  and  labor  thus  was  rendereil  i)ossible.  Later  this  vit'w 
was  dropped,  and  cases  where  such  .spjiaration  occurred  were  called  abnonnal.  In 
cows  the  sacro-iliac  joints  soften,  and  in  guin(vi-i)igs  all  the  joints.  esjM'cially  the 
pubis,  soften  and  enlarge,  allowing  wide  latitude  of  motion.  In  the  human  tiiere 
is  no  doubt  but  that  the  joints  soften,  thicken,  and  thus  enlarge  the  cavity  of  the 
pelvis.     The  bones  become  more  movable  on  each  other  and  thus  ix^rmit  the  pelvis 


380      THE  PATHOLOGY  OF  PREGNANCY,  LABOR,  AND  THE  PUERPERIUM 

to  accommodate  itself  to  the  mechanism  of  hil)or.  Matthews  Duncan  proved  tliis. 
The  mobihty  in  the  joints  renders  the  Walcher  position  effective  in  enlarging  the 
inlet,  and,  by  placing  the  parturient  in  the  exaggerated  lithotomy  position,  through 
the  same  conditions,  some  enlargement  of  the  bony  outlet  is  produced.  That  a 
small  pelvic  cavity  enlarges  during  pregnancy  the  author  is  convinced,  and  that 
the  tilting  (or  "nutation")  of  the  sacrum  favore  the  passage  of  the  fetus  is  another 
cHiiically  demonstrated  fact. 

When  the  softening  of  the  pubic  and  other  joints  becomes  marked,  s^Tnptoms 
resembling  arthritis  are  produced,  as  follows:  Pain  in  and  about  the  pelvis,  referred 
to  the  site  of  the  joints,  and  especially  to  the  particular  one  involved;  difficulty  in 
locomotion;  easy  tiring,  with  a  general  sense  of  weakness;  inal)ility  to  rise  from  a 
sitting  posture  without  raising  the  trunk  on  the  hands  or  outside  assistance;  relief 
by  w^alking,  but  soon  followed  by  pain  in  the  pelvis,  necessitating  rest;  the  condition 
is  worse  in  the  morning,  better  in  the  day,  and  w^orse  again  in  the  evening;  pain 
reflected  up  and  down  the  nerve-trunks  of  the  pelvis,  simulating  neuralgia,  or  even 
pains  in  the  hj'pogastrium,  simulating  abdominal  disorders.  When  the  patient  is 
bedridden,  the  case  is  decidedly  pathologic.  On  examination  no  cause  for  the  sjaiip- 
toms  can  be  found  until  the  condition  of  the  pelvic  joints  is  discovered.  The  ten- 
derness of  the  pubic  cartilage  is  the  most  prominent  finding.  The  sides  of  the  joint 
are  painless,  but  pressure  directly  over  the  middle  evokes  lively  expressions  of 
suffering.  Then  the  groove  may  be  found  over  the  pubis  or  with  the  finger  in  the 
vagina.  By  rocking  the  pelvis  one  can  feel  the  bones  ride  on  each  other,  especially 
plainly  if  the  woman  is  examined  while  erect  and  stands  first  on  one  foot  and  then 
on  the  other.  Deep  pressure  over  the  sacro-iliac  joints  elicits  pain,  but  not  over 
the  cocc\Tc.  The  gait  is  peculiar,  waddling — ''  like  a  duck,"  as  one  woman  expressed 
it.  A  distinct  rising  and  falling  of  the  crests  of  the  ilia  can  be  seen,  which  is  not  all 
due  to  the  tilting  of  the  pelvis.  The  distress  in  walking  may  sometimes  be  a  real 
pain,  referred  to  the  affected  joint  or  joints.  The  affection  occurs  in  the  latter  half 
of  pregnancy,  in  multiparae  more  than  in  primiparae,  is  often  combined  with  varicose 
veins,  the  joints  under  these  conditions  seeming  to  partake  of  the  general  imbibition 
of  the  tissues  of  the  pelvis;  it  often  recurs  in  successive  pregnancies. 

During  labor,  if  the  sacro-iliac  s%-iichondrosis  is  loose,  the  ilimn  may  be  dis- 
located on  the  sacrum,  a  condition  which  was  noted  bj'  ^Madame  Lachapelle.  A 
case  of  this  kind  is  reported  by  Bates,  of  Denver.  The  joint  may  rupture  during 
operative  or  even  natural  delivery.  After  delivery  the  solidity  of  the  pelvis  is  rapidly 
restored,  unless  the  synchondroses  were  injured,  in  which  case  the  patient  may  be 
bedridden  for  weeks  or  months.  IMilder  cases  of  injury  to  the  sacro-iliac  joints  are 
undouljtedly  commoner  than  is  generally  believed.  Such  injury  explains  many  of 
the  prolonged  backaches  and  neurasthenic  states  following  parturition.  An  ortho- 
pedist should  be  drawni  in  consultation  in  such  cases. 

How  closely  this  condition  is  related  to  osteomalacia  has  not  yet  been  dis- 
covered. It  bears  some  resemblance.  The  diagnosis  is  easy  if  the  disease  is  borne 
in  mind.  Neuritis  and  paraplegia  seldom  need  consideration,  but  are  easily  elimi- 
nated. The  prognosis  is  good,  but  the  possibility  of  rupture  of  the  symphysis 
should  be  remembered,  (See  Chapter  on  Ruptura  Sjnnphysis.)  During  preg- 
nancy curative  treatment  is  impossible.  External  applications,  rest  in  the  hori- 
zontal position,  and  general  hygiene  are  prescriljed.  A  tight  girdle  (Osgood's 
brace)  or  adhesive  straps  may  be  tried.

An  ovum  may  be  fertilized  and  remain  at  any  point  of  its  passage  from  the

after  jiartial  sal|iingectomy.  Pregnancy  may  occur  in  a  closed  accessory  honi  of 
the  uterus  and  on  the  fimbria  ovarica  of  tiie  Fallopian  tube.  In  the  latter  instaiu-e 
one  speaks  of  a  tubo-ovarian  form.  As  the  ovum  di.stends  its  container  other  struc- 
tures are  encroached  uj)()n.  adhesions  form  between  them,  and  the  primary  toix)g- 
raphy  of  the  gestation  is  modified.  When  the  tubal  wall  bursts,  the  fetus  escap-

of  tui)o-abdominal  pregnancy;  if  the  rupture  occurs  in  the  lower  portion  of  the 
tube,  between  the  folds  of  the  broad  ligament,  an  intraligamentous  sac  is  forme<l; 
if  the  sac  which  is  formed  in  an  interstitial  pregnancy  bursts  into  the  uterus  (rare), 
we  speak  of  tubo-uterine:  if  the  ovarial  pregnancy  goes  toward  term,  it  ahiiost 
always  becomes  ovario-alxlominal— the.se  are  all  secondary  forms,  and  clinically,  as 
well  as  anatomically,  hard  to  distinguish  from  each  other.

ject  was  frequently  noted,  and  recently,  since  operative  interference  has  Viecome 
coniinon,  an  enormous  literature  has  accumulated  (Wertli). 

Extra-uterine  pregnancy  is  quite  frecjuent,  and  occurs  also  in  the  lower  animals 
— the  ape,  cow,  sheep,  bitch,  ancl  hare.  Many  cases  of  rupture  of  the  sac,  or  tubal 
abortion,  and  spontaneous  recovery  undoubtedly  occur,  and  pass  under  the  diag- 
nosis of  appendicitis  or  alxlominal  colic.  "Prostitute^s'  colic"  is  surely  often  of 
this  nature.  It  is  more  frequent  in  city  than  in  country  practice;  oftener  after 
the  thirtieth  year — frequently  after  a  long  period  of  relative  sterility;  and  in  women 
who  have  had  an  antecedent  pelvic  disease.  Repetitions  of  the  accident  in  the 
same  tube  and  in  the  other  tube  have  been  reported,  and  intra-uterine  and  extra- 
uterine gestation  may  coexist. 

The  actual  causes  are  unkno\\ai,  but  the  following  have  been  advanced,  with 
more  or  less  plausibility,  in  the  order  named:  (1)  Salpingitis;  (2)  pelvic  adhesions; 
(3)  infantile  tubes  with  lack  of  cilia;  (4)  external  wandering  of  the  ovum;  (5) 
diverticula  and  accessory  tubes;  (6)  decidual  reaction  of  the  tubes;  (7)  disease  of 
the  corpus  luteum  (Frankel  and  Opitz). 

Salpingitis  may  act  either  by  the  loss  of  the  cilia,  which  should  favor  the  mo- 
tion of  the  ovum  to  the  uterus,  or  by  gluing  the  folds  of  the  mucosa  tubse  together 
and  forming  blind  pouches  in  which  the  ovum  is  caught,  or  by  occluding  the  tube 
through  the  kinks  or  swelling.  Gonorrhea  is  a  frequent  antecedent,  but  puerperal 
infections  and  other  inflammations  are  also  found.  Pelvic  adhesions  may  bind 
the  tubes  and  ovaries  down  and  compress  the  lumen  of  the  tube,  or  prevent  the 
escape  of  the  ovum  from  the  neighborhood  of  the  ovary.  Infantile  tubes  are  much 
convoluted  (Freund),  and  perhaps  have  little  propelling  power.  In  cases  of  ex- 
ternal wandering  of  the  ovum  it  may  have  grown  so  large  that  it  is  unable  to  pass 
the  lumen  of  the  tube,  and  during  the  long  journey  the  trophoblast  has  had  time 
to  develop,  so  that  it  can  attach  itself  anywhere,  or  perhaps  the  slow  motion  im- 
parted to  the  ovum  by  the  weakened  or  undeveloped  or  adherent  tube  gives  it  time 
to  become  fixed.     Much  of  the  above  is  purely  theoretic. 


PATHOLOGY 

Tubal  Pregnancy. — This  is  by  far  the  most  common  form.  Whether  the  ovum 
rests  in  the  ampulla,  the  median,  isthmic,  or  the  interstitial  portion  of  the  tube,  the 
course  is  the  same,  the  trophoblast  producing  cytolysis  of  the  cells  of  the  tubal 
mucosa,  and  the  ovum  then  burrowing  into  the  wall  of  the  tube,  in  a  way  distinctly 
analogous  to  that  of  pregnancy  in  the  normal  uterus.  A  decidua  may  or  may  not 
he  formed,  but  usually  one  finds  islands  of  decidual  reaction  in  ancl  near  the  im- 
plantation of  the  ovum,  and  even  in  the  other  tube.  As  the  ovum  grows  it  bulges 
the  wall  of  the  tube  inward,  occluding  its  lumen,  the  cells  of  the  opposing  surfaces 
necrose,  and  the  capsularis,  if  there  is  one,  fuses  with  the  opposite  side  of  the  tube. 
The  villi  erode  their  way  into  the  blood-vessels  and  between  the  muscular  fibers. 
Conditions  in  the  wall  of  the  tube  are  so  different  from  those  in  the  thick  decidua 
of  the  uterus  that  the  dangers  of  tubal  pregnancy  are  easily  grasped.  In  the  uterus 
the  ovum  develops  in  the  thick  decidua  and  in  a  mucous  membrane  capable  of  strong 
decidual  reaction,  which  membrane  might  really  be  considered  a  protective  wall 
against  the  advancing  army  of  villi.  The  blood-vessels  are  small,  and  the  muscle  of 
the  uterus  is  physically  adapted  to  stretching  and  hypertroi:)hy.  On  the  other 
hand,  in  the  tube  there  is  little  or  no  decidua,  and  the  advancing  villi  rapidly  eat 
their  way  into  the  muscle-fibers  and  into  the  blood-vessels.  These  latter  are  large, 
and  the  muscle  of  the  tube  is  not  so  capable  of  hypertrophy  and  stretching.  Indeed, 
in  the  tube  the  ovum  acts  like  a  rapidly  growing  destructive  neoplasm. 

The  ovum  may  be  arrested  between  two  folds  of  the  redundant  tubal  nmcous 
membrane,  or  it  may  attach  itself  to  the  top  of  a  fold  (Werth).     Minute  differences 


EXTRA-UTERIXE    PREGNANCY  383 

in  the  early  development  of  the  ovum  result  here,  hut  they  are  of  no  clinical  im- 
portance. In  either  case  the  f^rowiiiK  ovum  distends  the  tube  to  the  point  of  rup- 
ture. Some  hypertrophy  of  the  tuhe  occurs  in  ail  cases,  and  in  rare  ones  the  tui>e 
grows  until  term  without  rupture,  these  being  the  instances  where  it  has  Ixvn  aup- 
posed  that  muscle-fibers  could  develop  in  an  adventitious  sac. 

Usually  the  hypertrophy  of  the  muscle  of  tin-  tube  is  insufficient  to  accommo- 
date the  ('Kg,  and  the  fibei-s  at  the  jjiacental  site  being  separated  ami  destroyed  by 
the  erosive  action  of  the  villi,  a  weak  spot  here  results.  Any  traumatism,  as  "strain- 
ing at  stool,  a  jar,  coitus,  a  bimanual  examination,  causes  a  slight  hemorrhage 
at  this  .site,  with  a  rupture,  or  the  tube  bursts  from  ovcrdistention  of  the  thimied 
necrosed  wall,  and  the  villi  lie  free  in  the  peritoneum.  Bleeding  naturally  results  from 
each  of  these  occurrences.  If  the  site  of  the  rupture  was  on  the  free  portion  of  the 
tube,  the  hemorrhage  takes  place  into  the  peritoneal  cavity,  a  hematocele  fonning 
in  the  pelvis.  When  the  tube  bursts  into  the  broad  ligament,  a  hematoma  develops 
there.  Rupture  of  the  tube  is  the  usual  termination  of  isthmic  and  of  interstitial 
pregnancy,  aiul  it  almost  always  occurs  in  the  second  and  third  months. 

When  the  ovum  is  in  the  ampulla,  the  gestation  sac,  in  developing,  may  point 
in  the  direction  of  the  fimbriated  end  of  the  tube,  and  a  process  known  as  tubal 
abortion  is  the  usual  termination. 

The  course  of  tubal  al)ortion  resembles  that  of  uterine  abortion  very  closely— a 
hemorrhage  occurs  in  the  decidua  serotina,  loosening  the  ovum  from  its  bed.     The

blood  and  tiie  ovum  now  fill  the  overdistended  tube.  The  bag  of  waters  may  ruj>- 
ture  and  the  fetus  escape  among  the  clots  in  the  lumen  of  the  tube.  Blooti  oozes 
through  the  fimbriated  end  of  the  tube  and  clots  around  it,  slowly  forming  a  hemato- 
cele in  the  lower  pelvis.  The  ovum  and  clots  are  gradually  extruded  tiirough  the 
open  end  of  the  tut)e  into  the  jieritoueal  cavity,  and  they  are  all  finally  absorbed, 
unless  the  hemorrhage  has  been  so  great  as  to  demand  surgical  interference  (Fig. 
345).  If  the  extrusion  does  not  take  place  or  is  not  awaited,  the  hemorrhagt^s  into 
the  tube  destroy  the  ovum  and  it  becomes  converted  into  a  mola  carnosa.  very  like 
those  often  found  in  the  uterus  (Figs.  34G  and  347).  In  these  early  moles  it  is  rare 
to  find  the  little  fetus — it  has  been  destroyed  or  even  absorbed.  Unh-s-s  (»ne  finds 
the  fetus  or  tlemonstrates  villi,  the  diagnosis  of  ectopic  gestation  may  not  l>e 
made.  In  molar  formation  also  a  slight  amount  of  blood  may  ooze  into  the  ix*lvis 
and  bind  the  tube  to  neighboring  structures. 

Hematocele. — \'ery  soon  after  the  bhtod  touches  the  peritoneal  surface  it  clots, 
and  the  peritoneal  surface  also  throws  out  a  layer  of  fibrin.  .Vdhesions  are  thus 
(juickly  formed  between  the  tube  and  the  neighboring  organs,  and  the  l»h)o<I  is  en- 
capsulated. This  is  a  hematocele,  and  the  sac  is  composed  of  tiie  fibrin  mentioned, 
the  neighl)oring  organs,  mainly  intestines,  bound  together  by  adhesions.  When  a 
new  bleeding  occurs  from  the  end  of  the  tube,  the  newly  formed  sac  is  overdistended 
and  may  rupture,  the  process  of  adhesive  reaction  being  continued  a  shorter  or 
longer  ilistance,  in  the  direction  of  least  resistance.     Another  hemorrhage  causes  a

THE  PATHOLOGY  OF  PREGNANCY,  LABOR,  AND  THE  PUERPERIUM 


repetition  of  the  process,  and  the  woman  may  die  from  the  repeated  losses  of  blood. 
This  slow  hematocele  formation  is  the  rule  in  tuljal  al)ortion  and  tul)al  mole,  but  it 
may  occur  \\'ith  a  slow  rupture  of  the  tube  as  well. 

When  the  tube  bursts,  it  usually  does  so  suddenly,  and  a  profuse  intraperitoneal 
hemorrhage  results.  If  the  woman  does  not  die  from  shock  and  the  anemia,  this 
mass  of  blood,  too,  is  walled  off  and  a  large  hematocele  forms.  This  condition  is 
found  in  isthmic  and  in  interstitial  pregnancies.  Rupture  of  the  tube  may  occur 
in  any  part  of  its  periphery.  Sometimes  the  perforation  is  minute,  the  villi  seem- 
ing to  have  actually  eaten  a  hole  through  the  wall. 

Hematoma. — When  the  ru])ture  of  the  tube  takes  place  into  the  broad  liga- 
ment, the  two  folds  are  torn  asunder  by  the  blood,  and  one  finds  a  mass   lateral  to

the  uterus,  extending  varial)ly  to  the  wall  of  the  pelvis,  under  the  round  ligament, 
even  up  into  the  iliac  fossa. 

The  fetus  does  not  always  die.  Sometimes  the  rupture  occurs  at  a  point  in  the 
periphery  of  the  ovum  which  does  not  affect  the  placental  site,  and  then  the  embrj'o 
escapes  into  the  peritoneal  cavity  or  between  the  folds  of  the  broad  ligament  and 
continues  its  development.  These  are  secondar}'  abdominal  pregnancies.  Secon- 
dary abdominal  pregnancy  may  also  result  when  the  tube,  not  rupturing,  but  im- 
mensel}'  thinned,  forms  one  layer  of  a  sac,  which  in  the  main  is  composed  of  lamel- 
lated  fibrin  and  adherent  intestines  and  omentum.  Such  sacs  may  be  readily  pedun- 
culated at  operation.  If  the  fibers  of  the  tube  grow  and  are  very  slowly  distracted, 
the  pregnancy  may  also  develo]i  into,  and  ])etween  the  folds  of,  the  broad  ligament, 
without  the  violent  symptoms  of  rupture.  Still,  in  all  forms  there  may  he  late 
rupture  of  the  sac. 

Interstitial  pregnancy  (Fig.  348)  has  the  same  terminations  as  tubal,  that  is,

rupture,  mole,  and  abortion,  the  latter  oceurrinK  into  the  uterus  (rare).  The  comer 
of  the  uterus  is  developed,  distorting  the  rest  of  the  or^an.  Rupture  is  o{  late  oc- 
currence, because  the  uterine  wall  is  capable  of  more  hypertrophy  than  the  tubal, 
and  the  ovum  may  die,  or  it  may  develop  to  maturity  in  the  broad  ligament.  The 
gestation  sac  may  grow  into  the  uterus  and  then  continue  a.s  a  normal  pregnancy. 
(See  Angular  Pregnancy.)  Such  a  diagnosis  is  expcjsed  to  nrnch  question,  but  ca^es 
notinfreciuentlyoccur  where  this  explanation  of  the  phenomenciu  seems  very  probable. 
Ampullary  gestation  pursues  the  same  course  as  the  others,  but  alnjrtion  la  the 
usual  termination,  because  the  open  end  of  the  tul)e  is  near  by.  The  ovum  may 
be  inserted  on  the  fimbria  ovarica,  and  in  such  an  event  the  pregnancy  is  ahn<ist 
entirely  abdominal,  antl  the  sac  is  made  up  of  lamellated  fibrin  and  adherent  in-

testines,  uterus,  ovary,  and  omentum.     The  placenta  spreads  out  over  the  tul)e, 
ovary,  pelvic  wall,  and  back  of  the  uterus.     It  may  be  attached  to  the  omentum. 

Ovarian  Pregnancy. — This  is  one  of  the  rarest  fomis,  but  its  occurrence  is 
provetl,  there  Ixiug  mer  30  cases  on  record.  Xorris,  Young,  and  Shea  give  a  resume 
of  20  or  more  authentic  cases,  with  the  literature.  It  is  not  easy  to  decide  that  a 
given  case  is  truly  ovarian  in  origin,  Ix'cause  the  sac  (juickly  makes  adhesions  to  the 
tube  or  uterus,  or  a  jiregnancy  on  the  fimbria  ovarica  may  tear  lo(»se  from  its  at- 
tachment or  grow  over  onto  the  ovary,  and  one  cannot  decide  if  the  ItM-ation  of 
placental  tissue  on  the  latter  is  primary  or  secondary.  To  establish  the  anatomic 
certainty  of  an  ovarian  pregnancy  all  that  is  necessary  is  to  prove  that  "the  tul>e, 
inclu(hng  the  fiml)ria  ovarica  (excluding  also  gestation  in  an  accessory  tul)c),  is 
absolutely  free  from  any  part  in  the  formation  of  the  fetal  .sac"  (Werth).  Werth 
evidently  considers  primary  abdominal  j)regnancy  so  rare  that  it  need  not  be  con- 
sidereil. 


386      THE  PATHOLOGY  OF  PREGNANCY,  LABOR,  AND  THE  PUERPERIUM 

Ovarian  pregnancy  pursues  the  same  course  as  tul)al.  The  impregnation  of  the 
ovum  by  the  spermatozoid  takes  place  before  the  former  leaves  the  ovary,  and  if 
the  ovum  was  deepl}'  located  in  the  ovary,  the  sac  is  evenly  covered  by  ovarian 
stroma;  if  it  was  superficial,  the  fetal  sac  grows  out  into  the  peritoneal  cavity.  In 
both  cases  the  pregnancy  is  pedunculated  and  easily  removed,  though  it  does  con- 
tract adhesions  with  the  surrounding  structures.  If  the  ovum  was  near  the  liiluni, 
the  gestation-sac  may  become  intraligamentous,  spreading  the  utero-ovarian  liga- 
ment apart,  and  showing  the  tube  stretched  over  its  exterior,  as  occurs  on  a  cystic 
tumor  of  the  ovary  in  a  similar  location.  Rupture  of  the  sac,  with  hematocele,  is 
the  usual  termination,  with  or  without  death  of  the  fetus,  but  molar  formation  is 
also  observed.  One  may  not  say  a  hematoma  found  in  the  ovary  is  always  the  result 
of  a  pregnancy,  unless  chorionic  villi  or  parts  of  a  fetus  be  demonstrated  in  it. 
Rupture  of  a  Graafian  follicle  is  sometimes  attended  by  free,  even  threatening, 
hemorrhage,  and  hemorrhagic  ovarian  cysts  or  twisted  ovarian  tumors  may  cause 
pelvic  hemorrhage.  A  differential  diagnosis  of  such  accidents  from  ectopic  gesta- 
tion cannot  be  positively  made  before  operation. 

Later  Course. — If  a  tubal  pregnancy  terminates  by  abortion,  the  extruded 
"mass  of  clots  with  the  embryo  are  rapidly  absorbed.  Tubal  moles  also  disappear 
in  the  same  way,  but  more  slowly,  and  subsequent  permea])ility  of  the  tube  is 
established.  If,  in  rupture,  the  placenta  became  detached,  torn,  or  disorganized 
by  blood-clots,  the  fetus  dies,  and,  unless  advanced  beyond  the  eighth  week,  the 
little  body  is  absorbed.  The  blood-masses  slowly  shrink,  harden,  and  are  dissolved 
by  leukocytic  and  ferment  action,  disappearing  in  a  longer  or  shorter  time,  depend- 
ing on  their  size. 

If  the  child  escapes  alive,  it  may  continue  its  development  among  the  intestines 
or  in  the  broad  ligament,  i.  e.,  secondary  abdominal  pregnancy.  In  either  case  it 
may  have  escaped  inside  an  intact  amniotic  sac  or  naked.  A  new  sac  now  forms, 
made  up  of  fibrin,  adherent  intestines,  omentum,  uterus,  broad  ligament,  etc.,  de- 
pending on  the  location  in  which  the  fetus  happens  to  l^e.  In  the  structure  of  the 
sac  no  traces  of  the  original  container,  tulje  or  ovary,  will  be  found,  except  at  one 
place,  the  site  of  the  rupture. 

If  rupture  of  the  container  does  not  take  place,  ])ut  the  tul)e  or  the  ovary  dis- 
tends, accommodating  the  growing  ovum,  a  large  pelveo-abdominal  sac  is  formed 
which  becomes  adherent  to  all  the  surfaces  it  touches — pelvic  wall,  uterus,  bladder, 
rectum,  intestine,  omentum,  liver,  spleen,  stomach.  This  sac  in  structure  shows  the 
tissue  of  the  original  site  of  implantation  of  the  ovum,  such  as  tube,  ovary,  together 
with  lamellated  fibrin,  muscular  fillers  from  neighlioring  organs,  especially  the  broad 
ligament  and  the  peritoneum,  to  which  it  at  first  adhered.  The  sac  varies  in  thick- 
ness from  1  mm.  to  several  centimeters,  depending  on  the  amount  of  fibrin. 

The  placenta  is  spread  out  over  the  tissues  adjacent  to  its  first  point  of  develop- 
ment, is  usually  thin,  but  otherwise  like  a  uterine  placenta.  The  blood-vessels  in 
the  neighborhood  of  the  placenta  are  enormously  dilated,  and  many  new  ones  are 
formed — this  especially  when  the  omentum  is  used  to  help  nourish  the  placenta. 
In  one  of  the  writer's  cases  the  newly  formed  blood-vc^ssels  in  the  omentum  were  as 
large  as  crows'  quills,  had  very  thin  walls,  tore  easily,  and  were  innumerably  dis- 
tributed over  the  sac. 

In  one  or  the  other  of  these  fashions  the  secondary  abdominal  pregnancy 
may  go  to  term.  Spurious  la])or  now  sets  in,  the  child  dies  as  the  result  of  hemor- 
rhage into,  or  dislocation  of,  the  placenta,  or  may  not  die  until  later,  and  nature  tries 
to  get  rid  of  the  foreign  body.  The  contractions  of  the  uterus  expel  the  decidua, 
and  usually  the  attendant  hemorrhage  is  slight.  At  any  period  of  pregnancy  the 
sac  may  rupture,  or  the  child  may  die  and  the  changes  al)out  to  be  described  may 
be  inaugurated.  Spurious  labor  with  expulsion  of  the  uterine  decidua  may  follow 
the  death  of  the  child  at  any  time.     There  is  always  a  degree  of  peritonitis  in  ectopic 


EXTRA-UTERINE    PREGNAN'CY  :i87 

gestati<jn  with  hemorrhage,  and  this,  aceording  to  Dudgeon  and  Sargent,  is  due  to 
the  Stui)liylococcus  alWus,  and  is  a  conservative  process.  Jaundice  is  also  frequent 
from  al>sorption  of  more  Ijlood-pigment  than  the  hver  can  take  care  of. 

After  the  death  of  the  fetus  it  first  becomes  macerated,  as  in  intra-uterine  preg- 
nancy, tlH'ii  the  hfjuor  amnii  is  absorbed,  the  sac  lays  itself  onto  the  bo<ly,  a  zone  of 
granulations  fills  the  interspaces,  and  the  soft  parts  of  the  fetus  are  abs<jrb<'d,  i.  e., 
it  is  skeletonized.  By  way  of  the  blood,  or  by  pa.ssing  througli  the  intervening 
wall  from  contiguous  structures,  especially  the  l>owel,  infecti(jn  may  gain  entry  to 
the  mass,  and  it  suppurates,  the  pus  finding  its  way  out  through  tli<'  bladder,  the 
rectum,  or,  least  (jften,  the  vagina  or  abdominal  wall.  (Edema  bullosum  can  Ik? 
seen  in  the  bladder  when  the  i)erf(jrati(jn  into  this  organ  Ix-gins.  Through  the  fistula 
are  pa.ssed,  first,  the  broken-down  fluid  placenta,  then  the  soft  parts  of  the  fetus, 
and  finally  the  separate  bones,  by  a  process  of  suppuration  which  may  last  months 
or  years,  and  which  the  patient  may  not  survive.  Sometimes,  even  after  months, 
the  woman  dies  from  hemorrhage  due  to  rupture  of  the  sac,  sometimes  from  peri- 
tonitis, but  rarely,  since  firm  atlhesions  have  walled  oi\  the  ilanger-zone. 

Another  termination  after  death  of  the  fetus  is  mummification,  the  child  dr>'ing 
up,  and  in  this  state  it  may  be  found  years  after.  Absorption  of  the  water  of  the 
fetus  takes  place,  and  it  is  surj)rising  how  well  its  tissues  are  j)reserved.  Calcium 
salts  are  tleposited  in  the  sac  around  the  fetus,  ami  if  these  are  abundant,  the  child 
is  inca.sed  Ijy  a  shell  or  even  partly  calcified  itself — lilholcclyphos,  or  lUhopedioii 
("stone  child").  Wagner  had  a  case  where  a  munmiified  fetus  was  carried  for 
twenty-nine  years,  and  \'irchow  one  for  twenty-<'ight  years.  Smith  descrilx's  a 
calcified  fetus  which  was  removed  from  a  woman  ninety-f(jur  years  old  sixty 
years  after  conception.  There  are  many  ca.ses  on  record.  Suppuration  may  occur 
at  any  time  even  after  calcification  is  marked. 

Changes  in  the  Uterus. — In  response  to  the  stimulus  of  pregnancy  (what  it  is, 
we  do  not  know),  the  uterus  hypertroi)hies  as  if  it  were  carrying  the  ovum  itself. 
It  enlarges  to  the  size  of  a  three  months'  pregnancy,  its  walls  are  thick,  and  it  ex- 
hibits intermittent  contractions.  A  decidua  develops  in  it,  and  this  maj'  lx>  as 
much  as  1  cm.  in  thickness,  presenting  all  the  characters  of  an  intra-uterine  preg- 
nancy decidua,  except  that  it  contains  no  chorionic  rilli.  At  the  time  of  spurious  labor 
or  spurious  abortion  the  decidua  is  cast  off,  either  in  one  piece,  as  a  ciust  of  the  uterine 
cavity,  or  in  large  shreds  or  ))!a(iues,  sometimes  accomj>anied  by  fetor. 

Combined  extra-  and  intra-uterine  pregnancy  is  not  very  rare,  Weil>el,  in  IIK).'), 
having  collected  oviT  119  cases.  Double  tubal  gestation  has  Ix'en  observed,  also 
two  gestation-sacs  in  one  tulx\  Twins,  and  even  trijjlets,  have  In-en  found  in  one 
sac.  Fa'tus  ])apyraceus  may  also  occur  in  combined  gestations,  as  well  as  in  twin 
ectopic  gestation. 

Extra-  and  intra-uterine  jMcgnancy  offers  a  very  serious  prognosis.  Alnjrtion 
of  the  uterine  ovum  ])recedes  or  follows  the  rupture  of  the  ectopic  sac,  Init  death 
from  internal  hemorrhage  may  occur  bi-fore  al)ortion  takes  place.  Rarely  the  woman 
goes  to  term,  and  then  labor  is  usually  siK)ntaneous,  but  <leath  frecjuently  follows 
from  internal  hemorrhage  or  sepsis  starting  from  tlu'  abdominal  mass.  The  extra- 
uterine fetus  rarely  obstructs  the  passage  of  the  intra-uterine.  If  the  ectopic  preg- 
nancy is  successfully  removed,  the  patient  may  go  to  term  with  the  otUvr  tme 
normally. 

Repeated  extra-uterine  pregnancies,  after  months  or  years,  an'  n()t  seldtuu  ol>-

CLINICAL  COURSE 
Rarely  ilo  the  first  months  of  an  ectopic  gestation  pass  witliout  symptoms  which 
direct  attention  to  the  pelvis  as  the  seat  of  troul)le.     Once  in  a  while  a  woman,  pre- 


388      THE  PATHOLOGY  OF  PREGNANCY,  LABOR,  AND  THE  PUERPERIUM 

viously  perfectly  well,  has  sutklen  symptoms  of  internal  hemorrhage  and  may  die 
from  the  same  even  before  a  diagnosis  can  be  made.  Medicolegally,  the  question 
of  foul  play  may  have  to  be  settled  in  such  instances. 

Usually  the  patient  misses  a  period  and  has  the  ordinary  concomitant  s^^nptoms 
of  early  pregnancy,  but  soon  complains  of  pains  in  the  lower  abdomen,  especiall}'^ 
on  the  affected  side — cramp-like,  due  to  uterine  and  tubal  contractions.  There 
may  be  mild  pelveoperitonitie  symptoms.  After  a  few  weeks  irregular  bloody 
vaginal  discharges  appear,  which  the  attending  physician  believes  indicate  a  tlireat- 
eiiing  abortion.  On  the  occasion  of  a  jar,  a  strain,  coitus,  or  an  examination  a 
sudden  severe  pain  is  felt  on  one  side,  the  patiejit  feels  faint  or  dizzy,  and  may  vomit 
or  be  nauseated.  Sj'mptoms  of  shock  ma}^  appear,  and  the  shock  may  be  due  to 
the  sudden  distention  of  the  tube,  to  irritation  of  the  peritoneum  by  blood,  or  to  the 
great  loss  of  blood.  The  pains  continuing,  a  piece  or  all  of  the  uterine  decidua  is 
discharged.  A  careless  attendant  will  now  conclude  that  the  abortion  has  taken 
place.  These  sjanptoms  may  indicate  that  a  hemorrhage  has  occurred  in  the  tube, 
or  through  it  into  the  belly,  or  that  a  rupture  of  the  tube  has  taken  place.  Rarely 
is  the  first  hemorrhage  so  severe  that  the  patient  dies — clotting  occurs  at  the  site 
of  rupture  and  the  blood  is  absorljed,  the  acute  s^inptoms  subsiding  in  two  or  three 
days,  the  whole  process  terminating  in  three  to  six  weeks.  Again,  because  the  clot 
is  disturbed  or  the  blood-pressure  raised,  the  hemorrhage  recommences  in  a  few 
hours  or  daj's, — almost  never  after  weeks, — and  the  patient  maj^  die  from  a  slower 
anemia  or  from  a  second  or  third  severe  hemorrhage.  Tubal  mole  seems  to  cause 
repeated  hemorrhages,  the  hematocele  sac  breaking  at  different  points,  fresh  ad- 
hesions forming,  and  new  additions  to  the  sac  being  made.  If  the  case  is  not  treated, 
nature  often  works  a  cure,  the  sac  being  bound  off  by  firm  adhesions  and  the  clots 
being  slowly  absorbed.  Nowadays,  however,  most  cases  are  operated  on.  In 
rare  cases  the  pain  may  be  referred  to  another  part  of  the  abdomen — the  gall- 
bladder, for  instance,  and  sometimes  intestinal  sj^mptoms,  like  an  enteritis, 
predominate.     Pyosalpinx  may  complicate  ectopic  gestation. 

The  symptoms  of  rupture  of  the  sac  are  pain  on  the  affected  side,  sometimes 
excruciating  and  sudden,  soon  spreading  all  over  the  lower  abdomen;  nausea,  some- 
times vomiting,  sometimes  diarrhea,  plus  evidences  of  hemorrhage  and  shock. 
That  shock  plays  a  real  part  in  the  sj^nptoms  is  certain,  because  the  author  has 
found  severe  prostration  ^\dthout  enough  blood-loss  to  explain  it.  The  striking 
pallor  with  slight  cyanosis  about  the  lips,  pearly  conjunctivae,  yawning  and  sighing, 
fast,  small  pulse,  and  extreme  weakness  reveal  the  fact  of  blood-loss.  Rarely  the 
pulse  is  slow — even  46,  but  feeble. 

Internal  examination,  if  the  blood  is  still  fluid,  will  usually  reveal  only  a  large 
uterus;  later,  when  the  blood  has  clotted  and  the  hematocele  is  forming,  one  can 
outline  the  mass  in  the  culdesac.  Under  particularly  favorable  circumstances  the 
finger  may  feel  a  soft  bulging  downward  of  the  culdesac  earlier.  When  the 
rupture  has  taken  place  into  the  broad  ligament,  a  hematoma  forming  here,  the 
pain  is  most  intense,  and  shock  overbalances  the  anemia,  because  of  the  tearing 
asunder  of  the  folds  of  the  peritoneum.  Internal  examination  will  always  disclose 
a  firm  mass  on  one  side  of  the  uterus. 

If  the  rupture  or  the  tubal  abortion  occurs  more  gradually,  the  sjnmptoms  are 
proportionately  less  stormy,  and  the  true  condition  may  not  be  discovered. 

If,  after  the  escape  of  the  ovum  into  the  peritoneal  cavity  or  into  the  broad 
ligament,  it  continues  to  develop,  sjanptoms  of  peritoneal  irritation  arise — pain, 
soreness,  nausea,  vomiting,  diarrhea  and  constipation  (sometimes  hemorrhages 
from  the  bowel),  bladder  disturbance,  loss  of  strength,  and  invalidism.  The  signs 
and  symptoms  of  pregnancy  continue,  fetal  movements  are  more  pronounced,  are 
painful,  and  may  distress  the  patient,  and  the  signs  of  tumor  in  the  belly  grow  with 
the  weeks.     This  tumor  may  be  asymmetric  or  median.     If  the  fetus  dies,  the  symp- 


EXTRA-UTERIXE    PREGXANCY  389 

toms  of  i)r('giiaii(y  disappear,  while  those  usually  iiiad*'  by  a  macerating  neoplasm 
become  noticeable,  evidently  due  to  a  toxemia.  Subfebrile  temperatures,  rapid 
pulse,  anorexia,  coated  tongue,  loss  of  weight,  and  invalidism  are  almost  always  in 
evidence.  Sui)icterus,  even  marked  jaundice,  is  often  a  striking  symptom.  Icterus 
with  fever  denotes  beginning  deconijxjsition  of  the  sac  and  contents.  Now  the 
patient  gets  really  sick,  since  an  abilominal  abscess  is  forming,  and  she  may  die  of 
sepsis,  of  peritonitis,  or  of  exhaustion  and  hectic,  from  prohjnged  suppuration,  the 
product  of  conception  being  gradually  expelled  through  a  fistula  into  the  bladder, 
the  rectum,  vagina,  or  belly-wall. 

If  the  sac  goes  on  io  litliojx'dion  formation,  involution  of  the  uterus  o<'curs,  the 
irritation  of  the  peritoneum  subsides,  and  the  patient  may  forget  that  she  was  preg- 
nant, and  may  even  have  children  normally.  Cases  are  on  record  where  an  extra- 
uterine tmnor,  offering  an  obstacle  to  delivery,  was  found  to  be  a  calcified  fetus. 

Hui)ture  of  the  sac  and  suppuration  may  occur  at  any  time  during  pregnancy, 
a  point  of  practical  imi)ortance  in  treatment.  The  symptoms  and  anatomic  course 
of  a  pregnancy  in  a  rudimentary  horn  of  the  uterus  are  .so  similar  to  those  of  ectopic 
gestation  that  the.se  subjects  should  be  considered  together. 


DIAGNOSIS 

Before  rupture  of  the  tuV)e  or  a  heniorriiag*'  into  it  the  diagnosis  of  ectopic 
gestation  has  hardly  ever  been  made,  because  the  tube  is  as  soft  as  an  intestinal  loop. 
Kanavel  reports  a  case  of  a  woman  who  had  ect(j|}ic  gestation  once  before,  diag- 
nosing a  recurrence  after  going  over  her  period  one  week,  and  operation  jjroved  she 
was  right.  Miller,  of  Pittsburgh,  discovered  a  mass  in  a  tube  which  he  had  palpated 
a  few  wwks  previously,  when  it  was  empty,  and  proved  the  ectopic  ])regnancy  by 
operati(^n.  .-Vlmost  all  the  ca.^es,  however,  where  such  a  diagnosis  has  been  rep<jrted 
were  tul)al  abortions  in  progress  or  tubal  moles.  Tul)al  mole  is  often  diagnosed. 
In  the  early  part  of  pregnancy  the  diagnosis  must  decide  if  an  ex-tra-uterine  tumor 
is  an  ovum  or  not,  and  during  the  latter  half  one  mu.st  decide  if  the  ovum  is  extra- 
uterine or  intra-uterine.  No  pelvic  condition  gives  rise  to  more  diagnostic  errors. 
The  author  has  seen  such  mistakes  made  by  every  gynecologist  and  surgeon  in  the 
city,  including  himself.  In  the  majority  of  cases  the  patient  will  give  a  hi.story  of 
previous  pelvic  inflammation,  either  gonorrheal  or  pueri>cral,  and  often  a  periotl  of 
sterility  elapses  before  the  aberrant  concejition. 

Direct  Diagnosis— First  Trimester. — When  a  woman  in  thereproductiveyx'rifKl, 
after  some  irregularity  of  tin-  menses,  such  as  going  over  the  jiroper  time  a  few  days 
or  having  only  a  small  amount,  or  even  a  more  profu.^e  flow,  complains  of  cramping 
pains  in  the  lower  abdomen,  mostly  unilateral,  ^^•ith  irregular  uterine  hemorrhage, 
the  suspicion  of  ectopic  pregnancy  is  aroused.  If,  suddenly,  an  excruciating  i^'lvic 
pain  occurs,  with  dizziness,  faintness,  or  collapse,  the  tliagnosis  is  almost  certain, 
and  is  confirmed  by  finding  an  extra-uterine  tumor  or  the  discharge  of  a  uterine 
decidua.  The  direct  diagnosis  of  fluid  blood  in  the  peritoneal  cavity  is  seldom  easy. 
A  sense  of  soft  resistance  is  found  in  the  i)osterior  vaginal  fornix,  but  the  utenis  is 
not  disi)laced;  indeed,  in  one  case  the  author  found  it  raised  uj)  in  the  s<'a  of  I)1<khI. 
Puncture  of  the  fornix  with  a  long  shan>  needle  may  rev«al  the  blocMl.  but  it  usually 
is  not  necessary  for  the  diagnosis.  Percussion  of  the  flanks  in  not  one  of  the  author's 
cases  gave  dulness,  even  though  a  quart  or  more  of  bUKnl  was  removed  at  operation. 
After  twenty-four  to  forty-<'ight  hours  the  l)lood-<lots  Ix'come  reailily  palpable  and 
now  displace  the  uterus— tiiat  is.  a  hematocele  forms.  When  the  di.scharge  of 
blood  is  slower,  a  peritubal  hematocele  forms,  which  increases  from  day  to  day.  and 
one  can  trace  the  advance  of  the  process  with  the  finger  by  succe.s.sive  examinations. 
The  hematocele  may  be  retro-uterine.  I)efore  the  uterus,  at  the  side.  lx»fore  or  lie-

toma  can  more  easily  l)e  diagnosed  from  the  stormy  beginning  and  the  firm,  tender 
tumor  at  the  side  of  the  uterus,  displacing  it  to  the  side  and  upward. 

Warning!  In  all  cases  where  the  history  of  the  patient  gives  only  a  hint  of  the 
possibility  of  an  extra-uterine  gestation,  the  examination  must  be  conducted  vdth 
the  utmost  gentleness  to  avoid  rupturing  the  sac.  The  author  witnessed  an  almost 
fatal  intraperitoneal  hemorrhage  on  the  examination  table. 

Direct  Diagnosis — After  First  Trimester. — AVhen  a  pregnant  woman  complains 
of  irregular  bloody  discharges  from  the  uterus,  excessively  painful  fetal  movements 
very  low  in  the  pelvis,  alxlominal  juiins  antl  distress,  with  intestinal  symi)toms  and 
invalidism,  one  may  strongly  suspect  an  ectopic  fetus.  The  demonstration  of  the 
enlarged  empty  uterus  alongside  the  fetal  sac  confirms  the  suspicion. 

The  direct  chagnosis  of  the  life  of  the  ovum  can  usually  be  made,  and  is  based 
on — (1)  The  absence  or  mildness  of  the  symptoms  of  rupture  of  the  tube  during  the 
second  and  third  months;  (2)  the  continuation  of  the  symptoms  of  pregnancy — 
nausea,  mammary  signs,  fetal  movements,  fetal  heart,  etc.;  (3)  the  presence  of  a 
loud  uterine  souffle  (in  ectopic  gestation,  contrary  to  normal,  this  sign  is  of  value  for 
determining  the  location  of  the  placenta);  (4)  the  absence  of  symptoms  of  toxemia 
and  of  suppuration;  (5)  the  continuation  of  the  gro^^'th  and  of  the  softening  of  the 
uterus  and  of  the  vagina;    (6)  the  gradually  increasing  size  of  the  abdominal  tumor. 

Differential  Diagnosis. — Only  the  most  common  difficulties  in  diagnosis  can 
be  consideretl,  and  these  will  be  given  in  the  order  of  frequency : 

Abortion  Ectopic  Pregnancy 

1.  Onset    quiet,    w^ith    gradually    intensifj'ing       1.  Onset    stormy,    with    irregular  and  colicky

resembhng  labor.  localized  on  one  side. 

2.  External  hemorrhage  profuse  or  moderate,       2.  External  hemorrhage  slight  or  absent  and

villi.

uterus  and  empty  pelvis. 

Before  every  curetage  for  abortion  it  is  wise  to  make  a  careful  bimanual  ex- 
amination to  rule  out  extra-uterine  pregnancy,  and  should  collapse  come  on  after 
such  an  operation,  strong  suspicion  of  rupture  of  an  ectopic  sac  must  be  entertained. 
Perforation  of  the  uterus  and  rupture  of  a  pus-sac,  or  other  abdominal  hollow  organ, 
give  the  same  sjinptoms,  and  it  may  be  necessary  to  open  the  belly  to  find  out  the 
true  conditions. 

If  infection  of  a  hematocele  or  of  a  hematoma  sets  in,  the  condition  cannot  be 
differentiated  from  a  pyosalpinx,  a  pelvic  cellulitis,  or  perimetritis,  unless  operation 
shows  the  hemorrhagic  nature  of  the  pelvic  tumor.  Jaundice  is  an  important  sign, 
since  it  usually  accompanies  a  degenerating  blood-clot.  Treatment  is  on  general 
principles  of  pelvic  infections. 

In  the  early  months  confusion  is  often  caused  Ijy  a  long  cervix  softened  at  its 
upper  part,  which  allows  the  fundus  to  bend  backward  or  to  the  side.  The  cervix  is 
hard,  is  held  to  be  the  uterus,  and  the  fundus  is  thought  to  be  the  ectopic  sac. 
By  straightening  out  the  uterus  the  diagnosis  may  be  made  certain,  ])ut  before 
attempting  to  do  so  the  presence  of  an  eccyesis  must  be  ruled  out.  Or  the  preg- 
nancy is  situated  in  one  horn  of  the  uterus  and  distends  this  side,  the  rest  remain- 
ing hard.  This  is  an  ''angular  pregnancy,"  "grossesse  angulaire,"  and  is  not  sel- 
dom the  cause  of  error  (Fig.  349).

392      THE  PATHOLOGY  OF  PREGNANCY,  LABOR,  AND  THE  PUERPERIUM 

Pregnancy  in  the  uterus,  complicated  by  ovarian  or  other  cystic  pelvic  tumors, 
may  give  rise  to  a  diagnosis  of  ectopic  gestation,  especially  since  the  accoucheur 
fears  the  danger  of  overlooking  the  latter  and  wishes  to  operate  on  this  account. 
The  mistake  is  pardonable  because  usually,  in  either  case,  the  abdomen  would  have 
to  be  opened.  Adnexa  tumors,  pyosalpinx,  hydrosalpinx,  and  ovarian  cyst  may 
be  mistaken  for  ectopic  sacs.  The  main  point  in  the  diagnosis  is  the  finding  of  the 
unchanged  uterus  alongside  the  tumor  and  the  absence  of  the  symptoms  and  signs  of 
pregnancy.  On  the  other  hand,  the  presence  of  the  early  signs  and  sjanptoms  of 
pregnancy  does  not  speak  against  an  extra-uterine  tumor  being  a  new-growth  or

inflammatory,  because  milk  in  the  breasts,  subjective  symptoms,  softening  and 
discoloration  of  the  cervix  and  vagina  occur  in  many  of  the  latter  pathologic  condi- 
tions— indeed,  even  under  normal  circumstances.  The  author  has  seen  colostrum 
run  in  fine  streams  from  the  nipple  of  a  nullipara  thirty-eight  years  old,  and  has 
expressed  milk  from  the  breasts  of  a  woman  eight  years  after  her  last  child. 

Pyosalpinx  cannot  always  be  differentiated  from  tubal  gestation,  and  they  may 
coexist.  The  presence  of  fever, leukocytosis  (the  polynuclear  nc^utrophiles), excessive 
tenderness,  evidences  of  acute  or  recent  gonorrhea,  and  l)ilateral  tumor  usually 
settle  the  diagnosis,  but   they  may  all  occur  in  extra-uterine  pregnancy.     If  by

mistake  the  Ik'IIv  is  opened  and  an  acute  pyosalpinx  found,  it  is  wiser  not  to  attempt 
its  removal  at  this  time,  because  such  operations  have  a  higii  primary  mortality. 

In  rare  instances  the  differential  diagnosis  of  rupture  of  a  gestation-sac  with 
collapse  must  be  made  from  rupture  of  a  pus-tube,  the  twisting  (jf  an  (jvarian  tumor, 
bursting  of  an  app<'ndiceal  abscess,  of  the  gall-bladder,  i)erforati(ni  of  the  stomach 
or  duodeimm,  nephrolithiasis,  ureteral  stone,  rupture  of  tin-  -picnic  artery,  but  the 
scope  of  this  work  forbitls  going  so  far  into  the  subject. 

Acute  appendicitis  has  not  seldom  been  mistaken  ioi  rxiru-uterine  pregnancy, 
and  when  real  pregnancy  co-exists,  the  differential  diagnosis  cannot  always  be  made.

In  all  ca.ses  where  the  diagnosis  is  uncertain  the  patient  should  be  put  in  a  well- 
equipped  hospital,  there  to  rest  in  bed  until  developments  occur  which  shed  enough 
light  to  allow  a  positive  statement.  Whenever  an  anesthetic  is  to  be  given  for 
the  examination  the  patient  likewise  must  be  in  a  hospital,  to  be  ready  for  immediate 
laparotomy  if  the  sac  should  be  burst  by  the  manipulations.

The  author  has  never  founil  it  necessary  to  use  a  souiul  or  t<»  curet  tiie  uterus 
to  make  a  diagnosis.  In  one  instance  the  patulous  cervix  invited  the  finger,  which

employed  when  all  other  means  fail  and  a  diagnosis  must  l>e  maile.  Further,  the 
information  obtained  is  not  always  unequivocal.  If  the  curet  brings  decidua  and 
no  villi,  the  condition  may  Ix?  either  intra-uterine  or  extra-uterine  pregnancy,  or 


394      THE  PATHOLOGY  OF  PREGNANCY,  LABOR,  AND  THE  PUERPERIUM 

both  (v.  Ott)  or  neither — only  a  dysnienorrheal  nieiubrane.  A  large,  thick,  rough 
decidual  membrane  expelled  from  the  uterus,  giving  a  more  or  less  complete  cast 
of  the  cavity,  without  chorionic  villi,  is  almost  pathognomonic  of  ectopic  gestation. 
It  may  be  expelled  after  the  operation. 

Skiagraphy  has  ])een  used  to  aid  the  diagnosis,  but  has  not  been  very  satis- 
factory as  yet,  for  obvious  reasons.  In  the  late  months  the  .r-ray  will  be  helpful. 
A  lithopedion  would  show  well,  but  it  could  not  be  differentiated  from  a  calcareous 
fibroid  unless  the  outline  of  the  fetal  bones  were  discernible. 

In  the  later  months  the  diagnosis  is  mainly  concerned  with  differentiating 
whether  a  given  fetus  is  intra-  or  extra-uterine.  These  points  will  aid  the  decision: 
History  of  unusual  occurrences;  of  rupture  in  the  early  months;  pelvic  peritoneal 
s\anptoms;  invalidism;  painful  fetal  movements  located  in  one  place  all  the  time; 
continual  pain  and  alxlominal  distress;  irregular  hemorrhage  and  discharge  of 
decidua;  finding  the  empty  uterus  alongside  the  tumor;  fetal  movements  active 
and  very  superficial,  seeming  to  be  almost  beneath  the  skin;  same  of  the  fetal  body, 
but  it  is  not  easy  to  make  out  the  presentation,  etc.;  heart-tones  exceptionally 
strongly  audible,  but  sometimes  not  to  be  heard  at  all;  sac  exhibits  no  contractions; 
round  ligaments  are  not  palpable  on  the  sac,  as  they  are  on  the  sides  of  the 
uterus;  the  tumor  is  not  symmetric  and  easily  definable,  like  a  pregnant  uterus; 
the  examination  is  painful  and  unsatisfactory. 

PROGNOSIS 

Naturally,  it  is  impossil^le  to  give  satisfactory  figures  in  such  a  multicolored 
disease  as  this.  Without  doul^t  the  outlook  has  i)een  painted  too  dark,  for  very 
many  ectopic  ova  die,  are  expelled  from  the  tul^e  as  abortions  or  by  rupture,  and 
the  patients  recover  without  a  diagnosis  having  been  made.  Many  women  recover 
under  expectant  treatment,  but,  of  course,  all  the  children  die.  In  the  cases  which 
go  to  term  the  fetus  is  usually  deformed  or  not  viable.  Sittner  collected  179  cases 
and  finds  that,  from  the  condition  of  the  fetuses,  one  may  allow  the  pregnancy  to 
go  on  unless  the  symptoms  of  the  mother  are  threatening.  Most  authorities  find 
the  opposite  concUtions.  Fifty  per  cent,  of  the  fetuses  are  deformed,  accorchng  to 
von  Winckel — the  head  in  75  per  cent.;  the  pelvic  end  in  50  per  cent.;  the  arms  in 
40  per  cent.  Pressure  l)y  neighl)oring  organs  causes  compression,  decubitus,  im- 
pressions, infractions,  etc.,  of  the  body,  and  disease  also,  as  hydrocephalus,  menin- 
gocele, cranioschisis.  These  are  due  to  amnionitis,  insufficient  liquor  amnii,  and 
cramping.  Amniotic  bands  and  velamentous  insertion  of  the  cord  are  common, 
and  the  placenta  may  be  thick  and  hard,  or  infiltrated  "with  hemorrhages. 

It  is  interesting  to  note  that  polyhydramnion  can  occur  in  extra-uterine  gesta- 
tion, though  oligohydramnion  is  the  rule  and  accounts  for  the  frequent  fetal  de- 
formities. Hydatid  mole  and  chorio-epithelioma  have  also  been  observed.  Hy- 
peremesis  gravidarum  and  eclampsia  may  enter  as  complications  (Pinard,  Spiegel- 
berg,  Horwitz). 

Schauta  found  75  recoveries  and  166  deaths  in  241  cases  treated  expectantly, 
and  quotes  Veit  as  saying  the  mortality  of  ectopic  gestation  with  hematocele  is 
25  to  28  per  cent.     Death  results  from  hemorrhage,  shock,  or  sepsis. 

The  prognosis  as  to  health  is  also  bad,  because  the  condition  leaves  peritonitic 
adhesions,  which  often  result  in  sterility;  if  untreated,  decomposition  and  abscess 
cause  hectic  fever,  invalidism,  etc. 

TREATMENT 
There  is  no  expectant  treatment  for  a  growing  ectopic  gestation.     The  "ex- 
plosive body"  (Werth)  must  be  removed  from  the  abdomen  as  soon  as  possible.     If 
the  diagnosis  is  made  Ix'fore  rupture  of  the  sac,  or  during  a  tubal  abortion,  the  indi- 


EXTRA-UTERINE    PREGNANX'Y  395 

cation  is  to  rcniovo  the  ovum,  prcfcrahly  l)y  lai)ur(jtomy.     Under  such  circum- 
stances the  operation  is  easy,  resembUng  an  ordinary  salpingectomy. 

If  the  pregnancy  is  advanced  Ijcyond  the  fcjurtli  iiKjnth,  th«'  fetus  having  con- 
siderable size,  the  adhesions  of  the  sac  to  neighlxjring  organs  being  extensive  and 
firmer,  and,  most  important,  tiie  vascular  connections  of  the  sac,  especially  the 
placental  region,  i)eing  nnicli  greater,  the  operation  becomes  more  and  more  for- 
midable. In  spite  of  Sittner's  statistics,  therefore,  it  is  best  to  interfere  as  early  a.s 
possible,  and  not  to  wait  for  the  child  to  be  viable.  Excej)tionally,  or  through 
religious  scruples,  the  i)atient  may  demand  delay  to  save  the  child,  and  in  this  ev<'nt 
she  must  be  put  in  a  hospital  to  await  the  time  of  (jjxration.  At  the  end  of  preg- 
nancy it  is  recommended  to  wait  for  the  fetus  to  die  and  ojx'rate  wven  to  twenty 
days  thereafter,  the  object  being  to  permit  thrombosis  of  the  ])lacental  ves.s<-ls  and 
the  consequent  diminution  of  the  blood-supply  to  the  ])arts  (Litzman).  This  ad- 
vice is  seldom  followed  by  experienced  abdominal  surgeons,  an<l  the  results  of  im- 
mediate operation  compare  very  favorably  witli  those  of  the  waiting  jKjlicy. 

The  operation  should  be  undertaken  only  by  one  skille*!  in  abdominal  Hirfjcrj-,  because 
complications,  hemorrhage,  injury  to  intestine,  ureters,  etr.,  are  ver>-  eomnion.  If  tlie'j)regnaney 
ia  intraligamentous  ()r  tubal,  without  many  adhesions,  it  is  often  poK<iblc  to  p<'<iun<ul:ite  ilic  tumor 
as  one  does  an  ovarian  cyst,  after  tj-ing  the  ovarian  vessels  at  the  brim  and  ciamjiinn  the  broad 
ligament  at  the  uterus.  The  plae(>nta,  together  with  the  eae,  may  then,  little  by  little,  be  (li.s.'^ectod 
olT  the  floor  of  the  pelvis,  clamping  and  tying  the  ve.ssels.  The  bleeding  areas  are  drie<l  by  suture, 
cautery,  packing,  or  .sewing  the  peritoneum  over  them.  When  the  i)lacenta  is  attaehtnl  to  the 
rectimi,  the  sigmoid,  the  small  intestine,  or  the  omentum,  one  will  come  upon  innumerable  large 
and  small  blood-vessels  running  from  these  organs  onto  the  sac.  These  blood-vep.«els  are  so  thin 
walle(l  that  they  seem  to  have  only  two  layers  of  cells,  for  they  break  under  thi-  lightest  touch, 
and  the  field  is  instantly  flooded  with  blood.  It  may  be  neces.sary  in  such  a  e:iw  to  oj)en  the  .sac, 
remove  the  child  and  as  much  of  the  sac  and  placenta  as  is  s;ife,  leaving  the  rest,  but  .«<wing  the 
edges  of  the  sac  to  the  abdominal  wall  after  firmly  j)acking  it.  Wliile  it  i.«  mof-t  desirable  to  remove 
the  whole  ovum,  this  way  may  le:id  more  surely  to  success.  The  remnants  or  the  whole  of  the 
placenta  separate  and  are  discharged  by  suppuration  in  the  course  of  four  to  si.xteen  weeks.  Wh<'n 
the  placenta  is  on  the  anterior  alidominal  wall,  the  primary  hemorrhage  is  great,  but  it  may  be 
checked  by  pres.sure  or  compression  of  the  aorta  high  above  the  bifurcation,  as  has  been  done  bv 
the  author  at  cesarean  sections.  In  one  of  tlie  author's  ca.'ies  tlu-  hemorrhage  from  vascular  ad- 
hesions absolutely  frustrated  all  attempts  at  hemostasis  by  a  skilful  surg(on  ;md  hims<-lf.  The 
placenta  was  adherent  to  the  omentum  and  gut,  the  former  being  simply  a  mesh  of  brittle  arteries 
and  veins.  In  a  similar  ca.se  Momburg's  belt  might  po.^jsibly  be  tri<Hl.  Several  cas«-s  have  Ixt-n 
operated  by  simply  removing  the  fetus  and  cord,  sewing  up  the  Ric,  and  lea\ing  it  for  later  ab- 
sorption.    The  results  do  not  recommend  the  procedure. 

Treatment  of  Rupture  and  Tubal  Abortion. — Since  the  diflerential  diagnosis 
may  not  l>e  i)()ssible,  both  conditions  are  treated  alike.  There  seems  no  doubt  but 
that  the  best  treatment,  as  soon  as  the  tliagnosis  of  ru])ture  of  the  sac  with  intra- 
peritoneal hemorrhage  ha.s  been  made,  is  to  ojx'n  the  In'lly  and  remove  the  pregnant 
organ.  Salt  solution  is  given  l)y  h^-iiodermoclysis,  and  the  belly  quickly  ojx-ned. 
The  author  us(>s  ether  anesthesia.  Blood  may  shoot  uj)  several  inches  from  the  in- 
cision. Onv  grasp  locates  the  uterus;  it  is  ptdled  uj)  into  tin-  womul,  and  a  <lamp 
put  on  the  broatl  ligament  of  the  atfected  side.  Another  gra.-^j)  brings  the  sac  into 
view,  and  a  clamp  is  put  on  its  pelvic  side.  Fresh  bleeding  is  thus  checktHl.  and  the 
removal  of  the  sac  is  now  undertaken  deliberately.  A  search  is  made  for  the  fetus, 
which  is  usually  found  very  near  to  the  site  of  rui)ture.  Tin-  largest  clots  are 
scooped  out,  but  no  time  is  wasted  in  the  peritoneal  toilet,  and  the  belly  is  raj^idly 
closed.  Salt  solution  is  given  continuously  under  the  brea.^ts  throughout  the  opera- 
tion and  after  it,  not  intravenously,  except  in  very  critical  ca.ses. 

If  one  is  callecl  to  a  ca.se  when  the  jirimary  hemorrhage  has  cea.'^nl,  the  patient 
recovering  from  the  shock,  one  may  wait  a  few  days,  but  must  be  ready  to  operate 
on  the  first  sus]iicion  of  renewed  hcMuorrhage.  Preparations  must  be  made  at  home 
or  the  woman  sent  to  a  hos])ital.     My  own  prefi'nnce  is  for  immediate  operation. 

If  a  hematocele  forms,  which  is  ea.sily  determined  by  the  hardening  and  form- 
ing of  the  pelvic  blood-mass,  one  may  remove  same  by  laparotomy,  l)v  vaginal  inci-

sion  and  drainage,  or  may  allow  it  to  become  absorljed.  Fehling  thus  treated  91 
cases  successfully.  The  patient  must  be  kept  under  hospital  observation  until  the 
mass  is  very  hard  and  firm — that  is,  until  it  is  certain  that  the  fetus  is  dead  and  that 
there  is  no  danger  of  further  hemorrhage.  She  should  stay  in  bed  until  absorjition 
is  about  completed.  Al^sorption  takes  four  weeks  to  four  months,  dep(>nding  on  the 
size  of  the  blood-tum.or.  While  most  small  hematoceles  become  absorbed,  the  large 
ones  are  very  slow,  and  if  they  do  not  rupture,  allowing  renewed  bleeding  w^hich 
demands  operation,  they  not  seldom  suppurate,  in  either  case  causing  i:)rolonged 
invalidism  and  leaving  permanent  damage  in  the  pelvis  and  consequent  sterility. 
This  is  especially  true  if  the  fetus  had  attained  some  size.     Such  patients  do  better

With,  operation,  and  the  author  prefers  the  abdominal  to  the  vaginal  method  (Fig. 
352),  since  it  gives  better  control  of  all  eventualities. 

If  a  hematocele  forms  but  the  pains  continue,  and  especially  if  the  ]iatient  has 
fainting  spells,  one  should  d(H;ide  that  hemorrhage  is  recurring  and  operate  at  once. 
Should  the  temperature,  chills,  rapid  pulse,  pain,  and  peritonitic  symptoms  point 
to  infection  of  the  ge.station-sac,  it  must  be  drained  as  soon  as  possible.  Suppurat- 
ing hematoceles  are  broadly  opened  through  the  posterior  culdesac  as  one  does  a 
pelvic  abscess,  and  a  soft-ru})ber  tulx^  inserted,  without  any  attempt  to  remove  clots 
and  without  irrigation.  If  tlu;  prc^gnancy  is  further  advanced,  but  accessible  from 
below,  the  same  method  is  employed.  If  it  is  already  an  abdominal  pregnancy, 
the  belly  is  to  be  opened,  the  sac  sewed  to  the  edges  of  the  incision  and  opened  the 
next  day  with  the  cautery,  thus  avoiding  infecting  the  general  peritoneum.  Its 
septic  contents  are  removed  piecemeal  and  slowly,  requiring  days  or  weeks.

CHAPTER  XXXT 
DISPLACEMENTS  OF  THE  UTERUS 

ANTEFLEXION  AND  ANTEVERSION 

Normally,  the  uterus  is  anteverted,  and  during  tlie  first  months  of  pregnancy 
this  anteversion  is  increased,  the  fundus  lying  heavily  on  the  bladder  (Fig.  110,  p. 
84).  Pregnancy  occurring  in  an  anteflexed  uterus  displaces  the  fundus  downward, 
also  pressing  on  the  bladder  and  diminishing  its  capacity,  but  in  both  instances  the 
uterus  is  soon  directed  upward  into  the  abdomen  by  the  obtusely  placed  pubis,  and 
incarceration  does  not  occur  unless  adhesion  or  neoplasmlockstheorganin  the  pelvis. 
Anterior  displacements,  according  to  Graill}'  Hewitt,  cause  hyperemesis  gravidarum, 
and  proper  treatment  is  curative.     In  rare  cases  this  is  true. 

Late  in  pregnancy  the  uterus  always  becomes  anteverted,  owing  to  the  dis- 
tention of  the  anterior  abdominal  wall.  When  this  becomes  pathologic,  we  call  it 
pendulous  abdomen  (venter  propendens,  ventre  en  besace,  Hangebauch),  and  in 
advanced  cases  the  fundus  may  be  inverted,  pointing  downward,  and  hanging  be- 
tween the  knees.  In  primiparse  pendulous  belly  is  very  rare,  and  usually  indicates 
the  existence  of  a  contracted  pelvis,  twins,  or  some  condition  preventing  engagement 
of  the  fetal  head.  Occasionally,  about  the  eighth  month,  the  belly-wall  gives  way 
suddenly,  the  uterus  falling  forward.  Striae  gravidarum  are  usually  present  in 
great  numbers  in  these  cases.  One  would  naturally  expect  pendulous  abdomen  to 
be  absent  in  athletic  women  and  common  in  those  of  indolent  habit,  but  the  author's 
experience  shows  that  both  are  equally  affected.  It  is  probable  that  a  congenital 
weakness  of  the  abdominal  plates  may  exist  and  be  causative  of  pendulous  belly, 
as  well  as  enteroptosis.  iVIultiparae  suffer  more  commonly  from  this  affection,  and 
it  increases  with  the  number  of  children.  The  other  factors  are  contracted  pelvis, 
increased  inclination  of  the  pelvis,  kyphosis,  lordosis,  spondylolisthesis,  very  large 
fetus,  twins,  polyhydramnion,  frequent  child-bearing,  and  tumors  complicating 
pregnancy.  Improper  habits  also  cause  weakening  of  the  alxlominal  supports;  such 
are  constipation,  wearing  ill-fitting  corsets  or  high-heeled  shoes,  carrying  children 
or  weights  on  the  protuberant  belly. 

During  pregnancy  pendulous  abdomen  causes  a  sense  of  weight  and  distention, 
dragging  pains  in  the  loins,  in  the  belly,  and  at  the  costal  insertions  of  the  recti,  often 
frequency  of  urination,  intertrigo  of  the  lower  abdomen  and  thighs,  occasionally 
varices  and  edema  of  the  vulva.  The  diastasis  of  the  recti,  which  by  the  laity  is 
called  "rupture,"  may  be  so  marked  that  the  uterus  falls  forward,  covered  only  by 
the  peritoneum,  a  thin  layer  of  fascia,  and  the  skin,  allowing  the  surface  and  the 
contents  of  the  uterus  to  be  f(^lt  with  startling  distinctness,  and  sometimes  even 
the  color  of  the  organ  showing  through — hernia  uteri  gravidi  abdominalis.  In  such 
cases  locomotion  may  be  hindered. 

During  labor  pendulous  abdomen  may  cause  serious  dystocia.  The  uterus  is 
thrown  so  far  forward  that  its  axis  forms  an  acute  angle  with  the  pelvic  axis;  the 
cervix  is  pulled  up  into  the  hollow  of  the  sacrum,  sometimes  even  alcove  the  promon- 
tory; dilatation  is  delayed,  and  the  posterior  uterine  wall  is  overstretched.  This, 
together  with  obstructed  labor  because  of  malposition  of  the  fetus  and  disturbed 
mechanism,  invites  rupture  of  the  uterus.  Malpresentations,  such  as  shoulder 
and  breech,  are  common  in  these  cases,  because  the  head,  in  spite  of  strong  pains, 
cannot  get  down  into  the  pelvis.     Malpositions,  especially  anterior  parietal  bone

presentation,  are  especially  prone  to  (jccur,  as  can  \n'  seen  in  Fig.  353.  Prolapse 
of  the  cord  and  extremities  may  also  cause  dystocia,  and,  o\\  in^i;  t<j  the  peculiar  shajHi 
of  the  uterine  tumor,  diagnosis  is  difficult.  In  the  child  facial  paralysis  has  Ix'en 
observed  from  pressure  of  the  neck  against  the  pubis,  and  the  autiior  found  shorten- 
ing of  the  sternocleidomastoid  nmscle,  with  temporary  torticollis,  as  the  result  of 
the  extreme  lateriflcxion  (jf  the  fetal  neck.  Should  the  shortened  muscle  tear  dur- 
ing spontaneous  labor  or  operative  delivery  and  i)ecome  inllamed,  a  iM'rmanent  wry- 
neck may  result.  The  child  is  exposed  to  all  the  dangers  of  the  abncjrmal  mech- 
anism of  labor,  and  the  fetal  mortality  is,  therefore,  higher. 

Treatment.     Prevention  aceom])lislies  a  good  deal.     The  corset  shouhi  Ik-  re-

the  latter  months  of  pregnancy  the  abdomen  shouUl  Ix*  supported  by  a  properly 
fitting  binder.  ]\Iost  of  the  "maternity  corsets"  on  the  market  exert  pre.'ssure  on 
the  fundus  in  a  downward  direction,  wlu-n  the  i)roiK'r  action  is  one  of  supjiort  from 
below.  The  ordinary  surgical  bimler  with  straps  over  the  shoulders  meets  tin-  in<li- 
cations  best,  the  principk'  being  well  shown  in  Un-  supporter  illii>t  r;it..l  by  Hirst 
(Fig.  354).

port after  getting  out  of  bed;  (e)  bj'  systematic  gymnastics  and  massage  of  the 
abdominal  muscles. 

In  cases  of  fully  developed  pendulous  belly  during  pregnancy  the  binder  here 
illustrated  should  be  worn  as  soon  as  the  uterus  rises  out  of  the  pelvis;   th(^  patient

should  lie  much  on  the  l^ack,  and  the  physician  should  examine  her  in  the  last  weeks 
to  discover  a  malpresentation. 

During  labor  the  binder  should  l)e  worn,  or  the  uterus  may  be  pulled  up  by  a 
towel  slung  over  the  shoulders  and  held  in  place  by  another  around  the  belly.  In 
some  cases  it  is  best  for  the  attendant  to  push  the  pendent  fundus  upward  during 
every  pain  until  the  head  enters  the  pelvis.  The  author  has  often  accomplished 
engagement  by  letting  the  patient  squat  in  an  aboriginal  attitude  (Fig.  355).  This 
procedure  is  also  recommended  by  King.     The  thighs  force  the  uterus  up,  and  the

As  u  rule,  after  tlie  lieud  engages  labor  proceeds  rapidly,  hut  sometimes  the  widely 
separate(l  recti  cannot  obtain  a  purchase  on  tiie  uterus  witli  its  contents,  and  delay 
in  the  second  stage  arises  (jr  rotati(jn  stops.  Unless  fcjrceps  are  applied,  the  uterus 
may  rupture.  The  exaggerated  lithotomy  position  (Fig.  405),  which  is  the  squat- 
ting position  with  the  patient  on  the  hack,  is  especially  useful  at  this  stage  of  lahor, 
and  should  always  he  tried  before  resorting  to  forceps.  After  delivery  of  the  head 
the  anterior  shoulder  may  stem  on  the  pul)is  and  cause  delay—  the  bctdy  of  the  child 
is  to  be  liftetl  up  by  a  hand  j lulling  up  the  abdomen,      in  breech  presentations,  as

ANTEFIXATION  OF  THE  UTERUS 
While  the  furor  for  the  operative  treatment  of  retrodisplacements  oi  tiie  uterus 
is  steadily  subsiding,  enough  has  been  done  to  provide  a  new  and  not  infre(|uent 
form  of  dystocia.  The  uterus  has  been  fastened  to  the  alHlominal  wall  by  fixation 
or  .susp(>nsion;  to  the  bladder — vesicofixation:  to  the  vagina — vaginofixation;  and 
even  under  the  bladder  in  the  vagina— the  Wat kin.s- Wert heim  op«Tation.  Furth<T. 
its  ligaments  have  been  shortened,  folded,  or  transplanted — indeed,  the  very  mul-

402      THE  PATHOLOGY  OF  PREGNANCY,  LABOR,  AND  THE  PUERPERIUM 

The  Alexander  and  allied  operations,  wliere  the  ligaments  are  shortened  or 
transplanted,  as  in  that  of  Andrews  (sewn  behind  the  uterus),  usually  give  little 
real  trouble  during  pregnancy  and  labor.  Abortion  is  slightly  more  frequent,  and 
abdominal  pain,  from  the  tugging  of  the  uterus  at  its  shortened  ligaments,  is  usually 
complained  of.  The  round  ligaments  grow  during  pregnancy,  and  after  it  undergo 
involution  as  ordinarily.  Often  the  result  of  the  operation  is  impaired  by  the 
changes  Avrought  by  gestation.  Onlj'  symptomatic  treatment  can  be  employed  for 
the  disturbances  during  pregnancy. 

Ventrofixation  and  ventrosuspension  (often  the  former  results  when  the  latter  is 
intended)  and  adhesion  of  the  uterus  to  the  abdominal  wall  following  celiotomy  not 
seldom  cause  serious  dystocia.  Lindfors,  in  68  cases  of  labor,  found  the  cervix  was 
high  in  27,  transverse  presentation  in  31,  and  trouble  in  third  stage  in  10.  There 
were  30  versions,  13  cesarean  sections,  10  high  forceps,  5  embryotomies,  5  tampo- 
nades for  postpartum  hemorrhage,  and  many  other  operations  necessar3^  There 
were  3  deaths.  It  is  claimed  by  Lindfors,  if  the  operation  is  properly  performed, 
there  is  almost  no  danger  of  trouljle  with  succeeding  pregnancies.  In  146  cases 
collected  by  Lapthorn  Smith  there  was  trouble  36  times — 10  abortions  and  3  deaths. 
In  my  own  experience  these  have  occurred :  Abortion,  shoulder  and  breech  presen- 
tation, obstructed  labor  requiring  cesarean  section,  placenta  prsevia,  inertia  uteri 
and  its  sequences,  retention  of  placenta,  postpartum  hemorrhage. 

Pain  in  the  scar  is  common,  and  occasionally  h^13eremesis  may  require  inter- 
ference during  pregnanc3^  Williams  quotes  Andrews'  collection  of  395  cases,  and 
adds  36  cases  of  cesarean  section.  Dickinson  reports  2  deaths — one  from  rupture 
of  the  uterus  and  one  from  late  shock  after  cesarean  section. 

The  frequency  of  abortion,  difficult  labor,  postpartum  hemorrhage,  and  the 
necessity  for  capital  operations  to  overcome  obstruction  should  forbid  the  practice 
of  ventral  fixation  in  child-bearing  women,  an  opinion  also  held  by  Cragin  and  Polak. 

Much  depends  on  the  site  of  the  fixation  scar.  If  in  the  fundus,  the  worst  forms 
of  dystocia  occur.  Then  the  anterior  wall  can  take  little  part  in  the  dilatation  of 
the  uterus.  It  hypertropliies  and  forms  a  roof  over  the  inlet,  while  the  posterior 
wall  thins  and  stretches  to  form  the  cavity  of  the  uterus.  The  cervix  is  thus  pushed 
toward  the  sacrum  by  the"  growing  anterior  wall,  and  pulled  up  out  of  the  pelvis  by 
the  tugging  of  the  posterior  uterine  wall.  One  may  find  the  external  os  on  the 
promontory  or  above  it,  and  the  internal  os  up  on  the  lumbar  spine.  More  or  less 
as>anmetry  is  the  rule,  the  fundus  stretching  to  one  side.  One  finds  the  tubes, 
ovaries,  and  round  ligaments  more  or  less  parallel  wdth  Poupart's  ligaments. 

Vaginofixation  caused  such  serious  dystocia  that  its  performance  on  child- 
bearing  women  was  very  soon  abandoned.  Now,  unless  the  tubes  are  resected, 
insuring  sterility,  it  is  very,  seldom  practised.  Uniting  the  round  ligaments  instead 
of  the  fundus  to  the  vagina  is  open  to  the  same  objections. 

Since  the  fundus  in  this  operation  is  attached  to  the  relatively  immobile  vagina, 
the  cervix  points  to  the  sacrum,  and  the  same  conditions  will  arise  as  in  ventro- 
fixation, only  more  exaggerated.  The  pelvic  inlet  is  roofed  over  by  the  hypertro- 
phied  anterior  cervical  and  uterine  wall;  the  os  is  high  up  in  the  abdominal  cavity, 
and  can  be  traversed  by  the  finger  only  after  the  whole  hand  has  been  passed  into 
the  vagina;  the  bladder  is  entirely  an  abdominal  organ;  the  posterior  wall  of  the 
uterus,  having  constituted  almost  solel}^  the  available  uterine  wall,  is  much  thinned; 
the  round  ligaments,  tul)es,  and  ovaries  converge  to  a  common  point  just  behind  the 
pubis  (Fig.  356).  Alxlominally,  one  finds  a  triangular  ut(»rine  tumor  with  the  broad 
base  at  the  inlet,  and  can  feel  the  round  ligaments  as  they  converge  toward  the 
pubis.     Sometimes  the  scar  is  visibly  retracted. 

During  pregnancy,  which  is  not  common  after  the  operation,  the  uterus  tugs 
at  its  false  attachments  and  may  break  them,  which  is  more  likely  in  abdominal 
fixations.     This  process  causes  much  pain  and  symptoms  of  peritoneal  irritation.

Abortion  occurs  in  one-fourth  of  the  cases  and  annoying  bladder  837nptoms  are  the 
rule.     Labor  often  conies  (jn  prematurely. 

Labor  is  complicated  by  premature  rupture  of  the  bag  of  waters  and  prolapse 
of  the  cord;  abnormal  presentation,  usually  shcjulder;  slow,  weak  pains,  or  strong 
but  inefhcient  pains,  l)ecau.se  of  the  vault  of  tin-  vagina  being  obstructed  by  the 
thick  septum;  postpartum  hemorrhage.  All  manipulations  are  rendered  laborious 
because  the  uterine  cavity  is  difficult  of  access,  since  the  hand  has  to  pass  a  crooked

canal  and  then  operate  over  the  border  of  a  ledge.     Even  the  lateral  p(>>ture  docs 
not  facilitate  the  operative  procedures  very  nuich. 

Treatment. — A  woman  who  has  had  an  operation  fixing  the  uterus  in  an  al>- 
normal  location  requires  careful  watching  during  ])regnancy.  Annoying  symptoms 
can  be  only  partly  relieved.  Threatened  abortion  requires  rest  in  UhI  and  opiates; 
if  the  abortion  otcurs,  the  accoucheur  must  see  that  the  uterus  is  absolutely  empty, 
and  that  the  drainage  of  its  cavity  is  good.     As  the  woman  nears  term  frequent 


404      THE  PATHOLOGY  OF  PREGNANCY,  LABOR,  AND  THE  PUERPERIUM 

examinations  should  be  made  to  determine  the  behavior  of  the  cervix.  If  it  is 
pushed  backward,  upward,  and  hi<2;her  into  the  abdominal  cavity,  trouble  in  labor 
will  surely  arise,  and  appropriate  measures  should  l)e  instituted.  Such  a  course  of 
pregnancy  after  ventral  operation  may  indicate  reopening  the  belly  and  release  of 
the  adherent  fundus,  allowing  gestation  to  go  to  term.  After  vaginofixation  such 
an  operation  would  be  imjjracticable.  If  the  woman  goes  into  labor,  a  (|uick  de- 
termination is  to  be  made  as  to  how  much  an  obstruction  the  cervico-uterovaginal 
septum  will  make.  If  the  hand  can  pull  the  cervix  down  and  easily'  bring  it  into 
the  axis  of  the  pelvis,  it  is  probable  that  nature  A\all  succeed  alone  or,  by  means  of 
the  metreur^aiter,  version,  forceps,  etc.,  the  case  can  be  successfully  terminated 
with  ordinary  methods;  but  if  the  cer\'ix  is  long,  high  above  the  promontory',  and 
hard  to  pull  down,  a  cutting  operation  will  usually  be  necessary. 

In  ventrofixations  either  a  vaginal  or  an  abdominal  cesarean  section  may  be 
selected,  but  the  former  is  quite  difficult  of  execution,  because  of  the  inaccessibility 
of  the  cervix.  In  cases  where  a  t^'jDical  vaginofixation  has  been  done  with  the  usual 
stripping  of  the  bladder  from  the  anterior  cervical  and  uterine  wall,  the  septum 
may  safely  be  split  medially  from  the  external  os  almost  to  the  pubis,  without  danger 
of  injuring  any  organ.  Since  one  seldom  knows  what  operation  has  been  done,  it  is 
wisest  to  open  the  abdomen  in  these  bad  cases.  In  infected  cases  a  Porro  operation 
is  indicated,  and  it  is  usually  technically  difficult,  because  of  the  extensive  adhesions, 
the  immense  varicosities  in  the  broad  ligaments,  and  the  abnormal  location  of  the 
bladder  and  blood-vessels.  A  word  of  warning  is  given  to  the  operator  attempting 
to  deliver  from  below,  to  remember  how  thin  the  posterior  wall  of  the  uterus  is, 
and  that  the  whole  organ  is  fixed  on  the  pelvis,  for  which  reason  rupture  is  to  be 
feared.  In  performing  version,  access  to  the  parts  which  lie  in  the  anterior  pocket 
above  the  ledge  separating  the  uterine  cavity  from  the  vagina  may  be  obtained  by 
turning  the  patient  on  her  side  and  the  operator  inserting  the  hand  from  behind. 
After  delivery,  either  vaginally  or  abdominally,  provision  for  uterine  drainage  must 
be  made  bj'  gauze  or  tul)e,  because  the  fundus  may  be  lower  than  the  cervix,  and 
the  lochia  may  accumulate  in  the  anterior  pocket. 


POSTERIOR  DISPLACEMENTS 

Retroversion  and  retroflexion  are  rare  in  nullipara?,  and  when  they  do  occur, 
usually  cause  sterility,  but  in  women  who  have  borne  children  both  displacements 
are  common,  and  less  often  are  the  cause  of  acquired  sterility. 

Causation. — While  the  pregnant  uterus  may  become  retroflexed  or  retroverted 
as  the  result  of  a  sudden  increase  of  the  intra-abdominal  pressure  when  the  bladder 
is  full,  for  example,  through  cough,  fall,  straining,  it  is  usual  that  the  pregnancy 
occurs  in  a  uterus  already  displaced. 

As  a  rule,  the  uterus  slowly  draws  itself  up  out  of  the  pelvis — that  is,  sponta- 
neous restitution  occurs.  Sometimes,  because  of  adhesions  binding  the  fundus  in 
the  pelvis,  or  because  of  shrinking  and  inflammatory  thickening  of  the  muscle  and 
serosa  at  the  angle  of  the  flexion,  or  because  of  tumors  or  a  prominent  sacrum,  which 
interfere,  spontaneous  restitution  is  hindered  and  the  retroflexion  becomes  estab- 
lished. It  is  impossible  to  guess  at  the  frecjuency  of  the  condition,  because  surely 
many  pregnancies  occur  in  retrodisplaced  utm  and  terminate  unobserved,  by  the 
rising  of  the  organ  in  the  abdomen  or  by  abortion. 

Clinical  Course. — Unless  the  displacement  of  the  uterus  is  complicated  by 
adhesions,  no  symptoms  are  complained  of  until  the  uterus  begins  to  press  on  the 
neck  of  the  bladder.  Sometimes  there  is  a  sensation  of  fulness  in  the  pelvis,  with 
bearing  do\vn,  or  pains  radiating  from  the  sacral  and  lumbar  plexuses.  At  the  end 
of  the  third  month  bladder  symptoms  appear — frequent  desire  to  urinate,  great 
pain,  and  the  necessity  to  strain  to  pass  water,  the  feeling  that  the  viscus  has  not

pat  ion  and  diarrhea  are  occasionally  noted.  Decided  symptoms  occur  long  before 
the  room  in  the  pelvis  is  entirely  filled  hy  the  growing  uterus,  and  usually  bring  the 
patient  to  the  physician.  Rarely  the  woman  waits  until  the  uterus  is  tightly 
wedged  in  the  pelvis.  As  a  rule,  the  sjTiiptoms  begin  in  the  third  month  and  the 
case  is  terminated  by  the  fifth,  but  sometimes  the  pregnancy  has  proceeded  to  the 
eighth  month,  and  in  partial  retroflexion,  to  term. 

Four  terminations  of  these  cases  are  possible:  (1)  Spontaneous  rectification; 
(2)  abortion;    (3)  partial  restitution;   (4)  incarceration. 

1.  Spontaneous  rectification  is  the  rule  about  the  third  or  fourth  month,  the 
fundus  rising  past  the  promontory  and  falling  forward.  Contraction  of  the  mus- 
cular fibers  of  the  anterior  uterine  wall,  aided  by  the  round  ligaments,  accomplishes

Fig.  360. — Retroflexio  Uteri. 
A  retroflexed  uterus  had  been  pushed  up  out  of  the  pelvis  by  means  of  a  colpeurynter  in  the  fourth  month,  and  the 
pregnancy  proceeded  to  term.      Labor  was  normal,  but  because  of  hemorrhage  the  placenta  had  to  be  removed,  which 
was  difficult  on  account  of  its  inaccessible  location.     The  flexion  of  the  uterus  had  persisted  throughout. 


this,  and  it  is  favored  by  putting  the  patient  to  bed,  thus  relieving  the  displaced 
uterus  of  the  abdominal  pressure.  The  change  usually  requires  some  days  or  weeks, 
but  may  occur  rapidly  in  twenty-four  hours  or  between  two  examinations.  Pelvic 
adhesions  may  delay  the  restitution,  but  usually  the  adhesions,  even  when  exten- 
sive, are  stretched,  torn,  and  even  absorbed.  If  the  adhesions  are  too  strong,  or 
if  the  changes  in  the  structure  of  the  uterine  wall  are  permanent,  the  uterus  is  dis- 
torted in  the  direction  of  the  attachment  of  its  wall,  which  portion  is  draw^l  out 
sac-like,  the  balance  of  the  uterus  dilating  to  accommodate  the  ovum.  Fig.  361 
shows  such  a  case.  Spontaneous  cure  is  commoner  in  retroflexion  than  in  retro- 
version, because  in  the  former  the  corpus  has  a  firm  body  to  ])ull  against — the  cervix. 
2.  Abortion  is  a  frequent  termination  of  retroflexed  pregnant  uteri;  indeed, 
habitual  early  abortion  is  often  caused  by  this  malposition.     The  lack  of  room  does

not  cause  the  abortion,  hut  the  uterine  action  is  started  by  disturbance  in  the  uterine 
and  pelvic  circakiti(Mi,  l)y  chronic  <'ndouietritis  the  result  of  the  couKestiiJu,  with 
iH'Hiorriuit^es  in  the  dccidua,  and  by  chnjuic  nu'tritis,  whicii  pcriiaps  was  the  original 
cause  of  the  displacement.  ( )wiiiK  t(j  the  strong  contractions  during  the  course  of 
abortion,  the  uterus  usually  rises  in  the  abdomen,  thus  hiding  the  cause  of  all  the 
trouble,  but  aiding  the  emptying  of  the  ovum  and  the  lochial  discharges.  Rarely — 
and  in  these  cases  there  are  adhesions — the  drainage  of  the  uterus  is  incomplete 
because  the  fundus  is  lower  than  the  cervix. 

3.  Incomplete  restitution  may  result  in  a  condition  known  a.s  retroflexio  uteri 
partialis.  This  term  is  applied  t(^  those  ca.ses  where  part  of  the  fundus  is  retained 
in  the  pelvis,  the  anterior  wall  expanding  in  the  abdomen  to  form  the  (num  con- 
tainer.    Many  forms  of  the  uterus  are  jjossible.     (See  Figs.  359-361.)     They  are

due  to  inveterate  adhesions,  tumors,  or  to  changes  in  the  uterine  muscle  or  s<Tosa 
at  the  point  of  the  flexion. 

These  cases  may  terminate  normally  at  term,  the  deformity  anil  ilislocati«)n  of 
the  cervix  being  finally  overcome.  Abortion  or  premature  lal)or  may  occur,  or 
incarceration  which  demands  early  interference,  and  if  at  term,  oix^ration. 

A  condition  known  as  sacciform  dilntation  of  (he  ulvrus  may  be  confountied  with 
partial  restitution.  The  cervix  is  found  lu'hind  or  abov<'  the  jnibis;  the  culdesac 
is  tilletl  with  i)art  of  tlu^  tlilated  cervix  or  the  lower  uterine  segment  (Fig.  301). 
It  is  usually  a  simple  matter,  by  means  of  the  finger  or  the  vul.*<<>lla,  to  pull  the 
cervix  to  the  median  line,  and  th(Mi  comjilete  delivery  in  the  natural  or  ordinary 
operative  method,  but  Dejiaul,  who  wrote  a  good  pafwr  on  the  sul>ject.  was  unable 
in  his  ca.se  to  find  the  os,  and  the  patient  died  undelivered,  though  he  had  made  an 
opening  through  the  posterior  uterine  wall. 

4.  Incarceration  of  the  growing  uterus  in  the  pelvis  is  the  most  serious  outcome, 
and  the  symjitoms  which  demand  interference  come  from  the  bladder.  This 
organ  cannot  be  emptied  properly,  becomes  enormously  distended,  reaching  even

to  the  ensifonn,  and  becomes  inflamed.  The  cause  of  the  retention  of  the  urine 
is  compression  and  cUstraction  of  the  urethra,  and  sometimes  edema  of  the  neck  of 
the  bladder  from  the  intense  congestion.  Ischuria  jiaradoxa,  or  constant  th-i])hhng, 
may  excoriate  the  parts,  especially  if,  in  addition,  the  uterus  becomes  infected  and 
a  septic  serous  discharge  issues  therefrom.  Uremia  may  occur  when  the  urine 
dams  back  into  the  kidneys,  l)ut,  curiously  enough,  eclampsia  has  not  been  ol^served, 
though  Halbertsma  says  that  compression  of  the  ureters  is  a  cause  of  eclampsia. 
If  the  retention  of  the  urine  is  of  slow  development,  the  bladder  hypertrophies, 
but  in  all  cases  of  any  standing,   with  or  without  catheterization,  cystitis  and

ammoniacal  decomposition  develop.  Hemorrhages  into  the  wall  and  into  the  bladder 
have  been  noted.  The  bladder  may  rupture  into  the  peritoneal  cavity,  with  acutest 
peritonitis  and  death,  or  into  the  connective  tissue  with  septic  urinarj'  infiltration, 
which  is  almost  always  fatal.  Or  the  bladder-wall  becomes  necrotic,  in  part  or 
wholly,  the  intestines  adhere  to  its  outside,  and  if  the  blatlder-wall  is  removed  or 
broken  by  sloughing,  the  urine  accumulates  in  a  new  sac  formed  by  the  adherent 
structures.  This  usually  ruptures  and  causes  general  peritonitis.  Gangrene  and 
separation  of  all  or  part  of  the  mucosa  are  not  necessarily  fatal,  because,  if  the  uterus 
is  emptied,  the  slough  may  l)e  expelled  through  the  urethra.  The  cause  of"  the 
gangrene  is  infection  of  the  necrotic  mucosa,  and  the  germs — usually  Bacterium

mucosa,  with  urinary  extravasation  between  the  layers,  has  been  given  as  a  cause 
of  tiie  necrosis.      Deatli  may  result  from  urinary  .sepsis  (Fig.  'M'>2). 

The  bladder  chums  our  chief  interest,  but  the  bowel  sometimes  shows  symp- 
toms, such  as  tympany,  constipation,  and  vomiting.  Occasionally  a  mucous  diar- 
rhea occurs.     Ileus  is  exceedingly  rare. 

Incarceration  of  the  uterus  may  lead  to  abortion  or  to  sejjtic  infection  of  the 
uterine  contents,  th(>  bacteria  passing  through  from  the  bladder,  or  ui)ward  from

do  not  wait  for  it  in  practice. 

Diagnosis. — This  is  .seldom  difricult  if  a  careful  examination  is  made.  An>'  j^ng- 
nant  woman  giving  a  history  of  dysuria  or  dribbling  urine  should  be  examined  for 
retroflexio  uteri.  Abdominally,  one  sees  and  feels  the  distended  bladder  as  an  elastic 
tumor  giving  a  good  wave  of  fluctuation.  If  the  bladder-wall  is  hyix'rtrophied.  the 
tumor  may  be  hard,  .\fter  catheterization,  which  is  invariably  necessary,  the 
changed  abdomen  is  striking.  \'aginally,  one  finds  the  cervix  pn-s.^ed  upward 
against  the  pul)is  or  even  alujve  the  j)ubis,  while  the  culdesac  is  filled  with  a  soft 
tumor  which  bulges  into  the  vagina  and  may  even  (late)  distend  the  perineum. 

The  ditYerential  diagnosis  must  be  made  from  extra-uterine  pregnancy,  fibroitl 
on  the  ])osterior  wall,  and  incarcerated  ovarian  tumor.  Concerning  ectopic  gesta- 
tion, the  reader  is  referred  to  the  appropriate  chapter,  buf  here  the  warning  may  be

culdesac  is  ne(Ml(>d  to  settle  the  existence  of  a  neoplasm  in  tln^  p<'lvis,  but  if  the  wo- 
man is  pregnant  and  a  neoplasm  co-exists,  the  diagnosis  is  formitlable. 


410  THE    PATHOLOGY   OF   PREGNANCY,    LABOR,    AND    THE    PUERPERIUM 

Retroflexio  Uteri  Gravidi  Pregnancy  with  Ovarian  Tumor 

1.  Svmptoms  of  incarceration  early.  1.  Absent  or  very  late. 

2.  Bladder  symptoms  pronounced.  2.  Absent  or  inconsiderable. 

3.  Tumor  in  question  symmetric  and  soft  all       3.  Usually    asymmetric,    hard,    and    tense    all 

over.  over  or  in  places. 

4.  There  is  no  other  tumor  above  the  pelvis.  4.  Often  can  feel   the  pregnant   uterus  above 

inlet  and  to  one  side. 

5.  Mo\'ing  the  cervix  imparls  an  impulse  to      5.  The  upper  tumor  (the  uterus)  can  be  moved 

the  tumor.  independently  of  the  tumor. 

6.  The    fornices    are    flattened,    at    least    not       6.  The  fornices  are  drawn  up  high,  sometimes 

drawn  up.  even  above  the  pubis. 

7.  The  tumor  in  the  culdesac  may  contract.  7.  Never. 

8.  May  distinguish  fetal  parts.  8.  Never. 

9.  May  outline  the  round  ligaments  per  rectum.  9.  Not  positive  (in  one  case  strands  simulated 

these). 

Incarceration  of  a  pregnant  horn  of  a  double  uterus  and  partial  retroflexion 
of  the  uterus  both  give  diagnostic  problems  which  may  not  be  solved  except  by 
laparotomy,  and  countless  mistakes  have  been  made. 

Diihrssen,  among  others,  emphasizes  the  differences  between  the  clinical  course 
and  diagnostic  findings  in  retrofle.xion  and  those  of  retroversion,  but  practically 
the  two  conditions  are  the  same.  Retroversion  may,  as  pregnancy  goes  on,  be- 
come a  flexion;  retroversion  produces  symptoms  of  incarceration  later  because 
the  cervix,  pointing  toward  the  abdominal  cavity,  can  develop  in  this  direction; 
retroversion  is  less  likely  to  reduce  itself  and  is  harder  to  correct  artificially.  In 
retroversion  one  finds  the  cervix  pointing  toward  the  navel;  in  retroflexion  the 
cervix  points  toward  the  cocc^^x,  and  one  feels  the  angle  between  it  and  the  fundus. 

Prognosis. — Most  cases  of  retrodisplacement  terminate  by  spontaneous  re- 
duction or  respond  easily  to  art,  and  nowadaj^s,  when  women  consult  the  physician 
so  readily,  a  neglected  case  is  a  rarity.  Gottschalk,  quoted  by  Diihrssen,  collected 
67  cases  of  death  in  which  were  16  cases  of  uremia  and  exhaustion,  7  of  sepsis, 
18  of  peritonitis,  11  of  rupture  of  the  bladder,  3  of  pyemia,  2  of  rupture  of  the 
peritoneum  and  vagina,  5  errors  of  art,  1  ileus,  and  4  unkno-v^Ti.  The  danger  of 
rupture  of  the  bladder  occurs  both  from  overdistention  and  from  brusk  attempts 
to  replace  the  uterus;  the  bladder  has  been  punctured  by  the  catheter  and  severe 
hemorrhage  into  it  may  result  from  too  rapid  withdrawal  of  the  urine.  The  uterus 
may  be  torn  by  attempts  to  replace  it,  but  the  greatest  source  of  danger  is  reten- 
tion of  urine,  with  cystitis,  gangrene,  or  ascending  infection,  etc. 

Treatment. — If  the  condition  is  discovered  very  early,  one  may  wait  a  while 
to  see  what  nature  will  accomplish.  A  gentle  attempt  to  replace  the  uterus  may  be 
made  at  the  first  examination,  and  if  successful,  a  hard-rubber  pessary  is  introduced, 
to  be  worn  until  the  end  of  the  fourth  month.  Otherwise  the  patient  is  instructed 
to  take  the  knee-chest  position  three  times  a  day,  and  to  sleep  on  the  side,  with  the 
buttocks  slightly  elevated.  If,  after  three  weeks,  the  condition  is  unchanged  or 
worse,  the  woman  is  put  to  bed,  and  a  determined  effort  for  cure  is  made. 

First,  the  bladder  must  be  emptied  and  kept  empty.  When  the  uterus  is 
incarcerated  this  is  not  so  easily  done,  because  the  urethra  is  very  long,  flattened, 
distorted,  edematous,  or  the  bladder  itself  divided  into  two  compartments,  only 
one  of  which  is  accessible  to  the  catheter.  Care  must  he  taken  to  avoid  producing 
a  false  passage,  and  a  soft  catheter  is  the  best  instrument.  It  may  be  necessary 
for  the  physician,  not  the  nurse,  to  use  a  silver  male  catheter.  Aids  to  catheteriza- 
tion are:  Sims  or  knee-chest  position;  using  the  right  sized  catheter— No.  12  to 
No.  15  French  scale;  pushing  up  the  fundus  or  pushing  back  the  cervix  with  two 
fingers  in  the  vagina;  pulling  down  the  cervix  with  a  vulsellum  (not  recommended 
by  author);  allowing  warm,  sterile  olive  oil  to  flow  through  catheter  while  being 
inserted;  extreme  gentleness  and  much  patience.  If  the  retention  has  been  great 
and  prolonged,  all  the  urine  should  not  be  withdrawn  in  one  sitting,  and  the  rate 
of  flow  must  be  very  slow.     After  an  interval  of  three  hours  the  bladder  may  be

complctoij'  emptied,  the  reiisoas  f(jr  this  advice  Ix-ing  that  the  sudden  relief  of  so 
iinineiise  an  alKloiiiinal  distention  and  peritoneal  stretching  may  cause  shock,  and 
the  blood  rushing  into  the  anemic  mucous  membrane  of  the  bladder  may  produce 
a  hemorriiage  in  it. 

Hy  saline  cathartics  and  glycerin  cn(>mata,  using  small  anunints  of  licjuid, 
the  i)o\vels  are  kept  free  and  tympany  prevented. 

Reposition  of  the  uterus  is  usually  easily  accomplished  after  the  bladder  is 
emptied,  and  it  is  aided  by  employing  the  knee-chest  position,  by  i)ulliiig  the  c<*rvi,\ 
down  with  a  vulscllum  (the  instrument  shown  in  l-'ig.  (j!)()  is  better),  and  pushing  the 
fundus  upward  and  to  the  side.  The  fundus  sIkjuM  be  brought  to  slip  alongside 
and  avoitl  the  promontory,  by  pressure  with  two  fingers  in  the  vagina  or  one  in  the

because  of  too  violent  numipulations.  Even  after  reposition  1  (ladder  necrosis  may 
occur  the  damage  having  alreatly  been  done.. 

If  manipulation  will  not  restore  the  uterus,  one  may  temporize  a  short  time, 
employing  the  following  measures:  {(i)  Knee-chest  position  every  four  hours  for 
fifteen  minutes,  with  continuous  rest  in  bed  on  the  side,  with  the  hips  elevated, 
and  frequent  emjitying  of  the  bladtler  and  rectum.  In  the  absence  of  .symptoms 
of  cystitis,  and  without  retention,  one  may  wait.  Urotropin,  5  grains,  medicinal 
methylene-blue,  1  grain,  are  to  be  given  four  times  daily  in  these  ca.^it^s;  (/>)  a  col- 
peurynter  with  Ki  ounces  of  water  is  jilaced  in  the  vagina,  and  the  foot  of  the  U'd 
elevated  18  inches.     Some  authors  recommend  mercury  to  fill  the  eolix»urynter. 


412      THE  PATHOLOGY  OF  PREGNANCY,  LABOR,  AND  THE  PUERPERIUM 

One  may  continue  these  gentle  efforts  for  several  weeks  until  successful,  but 
must  not  delay  until  cystitis  or  aggravation  of  the  condition  indicates  their  futility. 
Laparotomy  has  frequently  been  done  and  the  uterus  easily  raised,  the  adhesions 
being  broken  up,  or— and  this  seems  to  have  ])een  overlooked — simply  by  allowing 
air  to  get  under  the  retroverted  fundus.  The  belly  is  opened  in  the  interests  of  the 
child,  and  is  permissible  only  when  the  bladder  is  not  gangrenous,  and  in  the  ab- 
sence of  symptoms  of  acute  peritonitis — this  because  the  protective  adhesions 
around  a  gangrenous  bladder  may  be  ruptured,  or  the  softened  uterus  may  tear.

The  incision  is  to  be  begun  high,  at  or  above  the  navel,  and  then  enlarged  downward 
after  being  assured  that  the  bladder  is  not  in  the  way. 

If  conditions  are  not  right  for  laparotomy,  the  uterus  must  be  emptied,  but,  owing 
to  the  inaccessible  cervix,  this  may  be  difficult.  A  sharply  curved  sound  or  male 
bougie  may  enable  one  to  puncture  the  membranes,  and  during  the  resulting  con- 
tractions the  uterus  will  lift  itself  up  and  empty  itself,  or  permit  the  accoucheur 
to  do  it.  If  one  cannot  reach  the  os,  the  puncture  may  be  made  through  the  bulging 
posterior  uterine  wall,  using  an  aspirating  needle  ancl  syringe.  In  one  case  Bumm 
drew  off  enough  liquor  amnii  to  allow  the  replacement  of  the  uterus,  and  abortion 
did  not  follow. 

Posterior  hysterotomy,  with  removal  of  the  whole  ovum  in  one  sitting,  may  also 
be  done,  and  reference  to  Fig.  361  will  show  that  it  is  not  always  necessary  to  open 


DISPLACEMENTS   OF  THE    UTERUS

the  peritoneal  cavity.  If  this  operation  is  attempted  and  the  culdesac  opened, 
one  should  try  to  replace  the  uterus  by  conibinetl  manipulation  before  incising  it. 
If  successful,  the  pregnancy  may  go  to  term.  To  i)n'vent  recurrence  the  vagina  is 
tampone(l  for  several  ilays  and  then  a  large  Sniitli  pessary  worn  until  the  uterus 
is  too  large;  to  fall  back. 

Clangrene  of  the  bladder  is  diagnosed  by  the  discharge  of  foul  urine,  with 
flocculi  of  pus  and  shreds  of  membrane,  in  the  presence  of  se|)tic  fever,  ("ysto- 
scopically,  very  little  can  be  seen,  but  the  severe  cystitis  and  localized  necnjses  with 
hemorriiages  may  be  found  before  gangrene  has  set  in.  As  soon  as  the  diagnosis 
of  gangrenous  cystitis  is  made  the  ijladder  is  to  be  widely  opened  from  the  vagina, 
loose  pieces  of  tissue  removed,  and  freest  drainage  provided.     Urotropin,  alternat  ing

with  salol,  is  administeri'd,  o  to  8  grains  four  times  a  day.  Urinary  infiltration 
of  the  perivesical  spaces  is  to  l)e  sharply  watcheil  for,  antl  on  its  discovery  the  whole 
region  immediately  and  broadly  inci.sed,  al)ove  or  below  the  pul)is,  or  l)oth,  and 
the  freest  possible  drainage  established.  It  is  unsafe  to  open  the  uterus  or  iiuluce 
abortion  after  gangri'ne  of  the  bladder  has  begun  l)ecause  of  sepsis;  therefore  it 
is  best  to  drain  the  l)hukler  and  await  developments.  The  uterus  may  be  replace- 
able after  a  few  weeks,  or  more  safely  attacked  after  the  bladder  lias  cleansed 
itself  somewhat.  When  the  uterus  has  become  infected,  it  must  be  emptied,  or, 
if  this  is  impossible,  extirpated.  Nowadays  these  neglecteil  cases  areextn'mtly 
rare,  because  the  women  consult  the  jihysician  earlier. 

Partial  retroflexion  of  the  graviil  uterus  retjuires  treatment   on   similar  lines 
if  threatening  symptoms  arise.     At  term,  if  it   is  impossible  to  bring  the  cervix 


414  THE    PATHOLOGY   OF   PREGNANCY,    LABOR,    AND   THE   PUERPERIUM 

into  the  axis  of  the  pelvis,  one  may  have  to  deliver  through  the  posterior  cervical 
wall  or  do  an  abdominal  cesarean  section. 

Distortion  of  the  uterus,  by  its  adherence  to  the  abdominal  wall,  to  the  sides 
of  the  pelvis,  the  rectum,  etc.,  may  give  rise  to  serious  dj'stocia,  as  has  been  seen 
in  the  instance  of  antcfixations.  Figs.  363  and  3G7  give  diagrams  of  two  cases 
recently  under  the  care  of  the  author,  and  the  brief  histories  indicate  the  commoner 
complications  and  treatment. 

PROLAPSE  OF  THE  PREGNANT  UTERUS 

Procidentia  may  occur  in  the  very  early  months,  and  unless  replaced  leads  to  abortion,  but 
Wimmer  reports  a  case  of  a  six  months'  gestation  outside  the  vulva,  and  this,  according  to  Braun 
Fernwald,  is  the  only  authentic  one  on  record  where  the  pregnancy  was  so  far  advanced.  Relax- 
ation and  prolapse  of  the  vagina,  with  partial  prolapse  of  the  uterus  outside  the  vulva,  are  not  very 
rare.  They  may  occur  during  pregnancy  as  the  result  of  severe  trauma,  because  a  tendency  to  pro- 
lapse existed  before,  or  a  prolapsed  uterus  may  become  pregnant.     (See  Findley.) 

Spontaneous  retraction  of  the  prolapsed  portion  usually  occurs,  and  after  the  fourth  month 


FiQ.  370. — Hypertrophic,  Edematous,  and  Prol.\psed  Cervix  in  Pregnancy. 
Diagram  of  internal  findings  of  Fig.  369. 

the  tendency  to  fall  disappears;  indeed,  the  patient  may  feel  better  during  pregnancy  than  at 
other  times,  since  the  uterus  is  in  place.  If  spontaneous  reduction  does  not  take  place,  it  is  a 
simple  matter  to  return  the  womb  and  hold  it  in  position  by  tampons  or  an  air  pessary  until  it  is 
too  large  to  come  down.  Ulcerations  of  the  cervix  are  to  be  cauterized  with  10  per  cent,  silver  nit- 
rate and  all  infections  cured  before  labor  starts  in.  Rest  in  bed,  1:  3000  permanganate  douches 
three  times  daily,  and  roborant  diet  will  accomplish  this. 

An  irreplaceable,  completely  prolapsed  uterus  is  to  be  emptied. 

Extrusion  of  cystocele  and  rectocele  during  pregnancy  is  a  very  annoying  condition,  the 
exposed  parts  sometimes  being  eroded,  usually  varicose,  and  occasionally  inflamed.  Pruritus 
may  be  obstinate,  and  the  author  has  observed  several  cases  of  mycosis  \'ulva}  under  these  condi- 
tions.    Rest  in  the  horizontal  position  is  to  be  advised,  also  extreme  cleanliness. 

Eversion  of  the  vaginal  walls  occurs  in  multipara;  in  the  second  stage,  during  the  strong 
bearing-down  efforts,  especially  if  the  cervix  is  rigid  and  does  not  retract  above  the  head  (Fig. 
368).  The  cervix  may  appear  outside  the  vulva  as  far  as  one  or  even  eight  inches,  and  will  not 
go  back  under  pressure.  Delivery  is  more  or  less  difficult,  depending  on  the  degree,  but  usually 
possible,  though  many  of  the  children  die.  If  labor  has  to  bo  operative,  two  assistants  should 
hold  back  the  edges  of  the  cervix  and  the  everted  vagina  with  specula  while  the  delivery  is  being 
effected. 

Hirst  collected  27  cases  of  vaginal  enterocele,  to  which  the  author  can  add  one,  occurring  in  the 
service  of  the  Chicago  Lying-in  Hospital  Dispensary.  Here  the  hernial  opening  in  the  posterior 
culdesac  was  2H  inches  across,  but  the  coils  of  the  intestine  could  be  very  (>asily  replaced.  The 
treatment  of  cystocele  and  rectocele  during  labor  is  symptomatic,  the  parts  being  replaced  as 
much  as  possible  and  held  back  with  the  fingers  so  that  the  advancing  head  can  slip  through  the 
space  thus  pro\-ided. 

Hypertrophic  elongation  of  the  cervix  rarely  complicates  labor.  Conception  is  hindered 
and  dysmenorrhea  usually  calls  for  treatment,  the  cases  seldom  coming  to  the  accoucheur  until

of  the  cervix  was  dry,  cracked,  and  partly  eroded.     It  was  disinfected,  replaced,  and  retained  by  a

tampon;  the  prolapse  did  not  recur,  and  labor  was  normal.  Williams  refers  the  condition  to  an 
angioneurosis,  but  in  most  of  the  ctises  a  history  of  injury  hiis  been  obtained. 

During  labor,  when  the  head  is  arrest itl  high  up,  the  cervix  becomes  swollen  and  may  pro-

tenderly  pushtni  up  and  held  in  position  during  the  pains.  Soon  the  head  slips  down  p:»st  it. 
During  forceps  delivery  it  must  be  held  back  with  two  fingers  during  each  traction.  It  may

CHAPTER  XXXII 
ABORTION  AND  PREMATURE  LABOR 

It  is  said  that  almost  half  of  the  child-bearing  women  have  had  a  miscarriage 
before  the  thirty-fifth  year.  Hegar  said  that  there  is  one  abortion  to  eight  labors, 
but  in  all  probability  it  is  more  frequent  than  this.  In  the  author's  private  obstet- 
ric practice  24  per  cent,  of  the  women  gave  a  history  of  abortion,  which  is  probably 
below  the  actual.  A  specialist's  practice  does  not  represent  the  ordinary  run  of 
cases,  because  so  many  of  his  patients  are  primiparse  or  women  who  have  had  difH- 
cult  confinements  or  miscarriages  before. 

Stumpf  and  Franz  collected  large  statistics,  but  they  are  of  ciuestionable  value, 
as,  indeed,  are  nearly  all  statistics,  because  one  cannot  get  complete  information. 
Hospital  figures  do  not  represent  the  conditions  of  private  practice,  because  compli- 
cated cases  are  sent  to  the  hospital,  and  statistics  from  both  sources  are,  therefore, 
invalidated.  Further,  many  abortions  occur  in  the  first  weeks  and  pass  under  the 
diagnosis  of  delayed  or  profuse  menstruation.  Finally,  very  many  abortions  are 
deliberately  concealed.  In  general,  regarding  abortion  it  may  be  said  that  it 
occurs  more  frequently  in  multiparse  than  in  primiparse,  perhaps  because  there  are 
more  multiparse,  but  probably  also  for  other  reasons;  oftener  in  the  city  than  in  the 
country,  because  of  the  prevalence  of  gonorrhea,  the  easy  accessibility  of  the  abor- 
tionist, etc.;  oftener  among  the  lower  classes — but  criminal  abortion  is  probably 
more  frequent  in  the  educated  classes;  more  frequent  in  the  first  three  months  of 
gestation,  and,  of  the  three,  commonest  during  the  third  month;  more  frequent 
after  the  thirtieth  year.     Race,  civil  state,  and  color  seem  to  have  no  influence. 

The  reasons  for  the  more  frequent  occurrence  of  abortion  from  the  eighth  to 
the  twelfth  week  are :  The  ovum  is  not  strongly  attached,  and  is  weak  and  suscepti- 
ble to  outward  influences;  marked  changes  are  going  on  in  its  circulation;  since 
the  woman  is  not  sure  of  her  pregnancy,  she  takes  no  care  of  herself;  the  women  con- 
sider it  no  crime  to  get  rid  of  the  ovum  before  "quickening,"  and  think  abortion 
not  dangerous  in  the  early  months. 

Much  disagreement  exists  regarding  nomenclature.  Miscarriage  is  a  term 
used  by  the  laity  for  every  interruption  of  pregnancy  before  term,  and  the  word 
"abortion"  is  resented  as  implying  a  criminal  process.  In  scientific  description 
it  is  best  to  drop  the  former  and  retain  the  latter.  "Immature  labor"  has  been 
used  to  designate  the  interruption  of  pregnancy  from  the  sixteenth  to  the  twenty- 
eighth  week,  and  "premature  labor"  from  then  on,  the  term  abortion  being  limited 
to  the  period  before  the  sixteenth  week.  The  author  agrees  with  those  writers  who 
apply  the  word  abortion  to  all  interruptions  of  pregnancy  before  the  child  is  vial)le, 
that  is,  before  the  twenty-sixth  to  the  twenty-eighth  week,  and  the  expression 
premature  labor  to  those  terminations  of  gestation  after  the  child  is  vial)le,  l)ut  before 
term. 

Causation. — A  study  of  the  etiology  of  abortion  has  very  great  importance 
as  an  aid  to  science,  of  treatment,  of  the  prevention  of  subsequent  accidents,  and 
medicolegally.  Therefore  in  all  cases  the  accoucheur  should  search  carefully 
for  the  underlying  cause  and  make  a  note  of  all  his  findings. 

A  classification  of  the  causes  must  be  arbitrary,  since  they  are  very  numerous 
and  interact  on  each  other.     They  are  fetal,  maternal,  and  paternal.

Fetdl. — Death  of  the  fetus  always  hriiiKs  <ni  alxjrliuii,  and  every  fatal  anomaly 
of  the  fetal  body  or  its  appendages  is,  therefore,  an  etiologic  factor.

How  (Iocs  the  death  of  th<^  fetus  cause  ahortion?  (1)  The  ovum  does  iic^t  he- 
conie  a  foreign  body  and  stimulate  the  uterus  to  elTeet  its  expulsion,  hecau.se  the 
vascular  connections  may  he  kejjt  up  for  months  and  the  ehori(m  he  so  well  nour- 
ished that  it  grows.  If  the  ovum  is  destroyed,  this  explanation  would  hold.  (2) 
When  the  fetus  dies,  the  stimulation  of  the  gro^\i:h  of  the  ovum  cea.ses  and  the  altera- 
tion of  the  endometrial  reflex  l)rin<<;s  on  al)ortion — i)urely  hyj^othetic.  (3)  The  fetus 
may  develop  a  hormone,  wiiicii,  reaching  the  blood,  inhibits  uterine  action,  failing 
which,  al)ortion  results;  the  corpus  luteum  does  not  grow  after  fetal  tleath,  and  its 
restraining  influence  is  lost — hy]wthetic. 

Between  the  death  of  the  fetus  and  its  exjiulsion  a  period  varying  from  a  few 
hours  to  days,  Aveeks,  or  months  may  elapse.  This  is  called  nn'sscil  abortion. 
Pieces  of  ]ilacenta  may  remain  in  the  uterus  as  long  as  nine  months  (author)  and 
eleven  months  (Playfair).     Ries  found  villi  sixteen  years  after. 

Maternal  Causes. — Chronic  endometritis  is  the  most  frequent  cau.se  of  aI)or1i{m. 
and  esjiecially  of  the  habitual  early  interruption  of  pregnancy.  It  acts  by  predis- 
posing to  hemorrhages  in  the  decidua  which  kill  the  fetus  or  .stimulate  uterine  con- 
tractions; by  rendering  the  uterus  irritable  and  intolerant  of  the  oviun;  by  raising 
barriers  against  the  growth  of  the  placenta;  In'  not  allowing  the  ovum  to  obtain 
a  solid  nitlus  or  a  well-located  one  (placenta  pncvia).  Endometritis  deciduie 
glandularis  produces  a  condition  called  hijdrorrlura  graridaruni,  attende(l  by  the  sud- 
den periodic  discharge  of  accmnulated  secretions,  and  on  one  of  such  occasions  the 
uterus  may  be  urged  to  action.  Acute  gonorrhea  and  jjeri-uterine  infection,  for 
example,  saljMngitis  or  appendicitis,  occasionally  interrujit  gestation. 

Chronic  metritis  is  the  ustial  accompaniment  of  endometritis,  and  renders  the 
wom))  still  more  intolerant  of  gestation — the  "irritable*  uterus"  of  the  «)lder  writers. 
The  uterine  muscle  cannot  hyjiertrophy  and  expand  as  it  should. 

^Malformations  and  diseases  of  the  uterus,  infantili.sm,  single  or  ilouble-horned 
uteri,  fibroids,  ]ioly])i,  lacerations  of  the  cervix,  especially  with  coincident  cervicitis 
and  endometritis,  amjiutated  cervix — all  are  sometimes  causative.  Hetrtdiexion 
and  retroversion  have  already  been  referred  to  as  frc(|U(Mit  cau.ses  of  abortion; 
indeed,  sometimes  when  abortion  is  thfe.ifeiied  repl.ieement  of  tlu'  uterus  allows 
the  gestation  to  go  to  term. 

Acute  infectious  diseases  of  tlie  moiii<  r  oiicn  cause  abortion,  as  was  said, 
through  tlu>  disease  j^a.ssing  over  and  killing  the  fetus,  but  they  act  also  by  causing 
an  endometritis  which  shows  a  strong  tendency  to  become  hemorrhagic.  The 
suilden  rise  of  temperature  may  stinuilate  the  uterus  to  action,  as  also  may  the

hypercarbonization  of  the  blood  in  those  diseases  which  are  attended  by  cyanosis — 
for  example,  pneumonia.  Hemolysis  also  affects  the  fetus  through  the  anemia 
of  the  mother. 

Sepsis  should  be  added  to  the  list  of  infectious  diseases.  It  gains  entrance  to 
the  uterus  during  pregnancy  and  kills  the  ovum  primarily  or  secondarily.  In  cows 
epidemic  abortion  sometimes  occurs,  and  the  pathogenic  organisms  have  been  de- 
tected on  the  penis  of  the  bull  which  had  served  the  sick  animals  (Wallace). 

Maternal  sj^philis  is  a  frequent  cause  of  abortion,  either  by  passing  over  to  the 
child  or  by  destroying  it  through  changes  in  the  decidua. 

Trauma  or  xdolence  is  very  frequently  advanced  by  the  patient  to  explain  the 
accident,  but  unless  it  is  applied  to  the  uterus  direct,  we  must  assume  that  one  of 
the  predisposing  causes — endometritis,  etc. — is  really  active.  A  special  predisposi- 
tion must  exist  to  explain  those  cases  where  a  slight  jar,  a  misstep,  a  nervous  shock, 
an  automobile  ride,  and  other  mild  occurrences  bring  on  abortion.  On  the  other 
hand,  the  severest  injuries,  mental  and  physical,  are  sometimes  inflicted  on  the 
gravida  ^\athout  disturbing  the  uterus.  Thomas  quotes  a  case  where  a  pregnant 
woman  jumped  from  an  upper  "^dndow,  falling  through  a  shed  onto  a  stone  flagging, 
but  carried  through  to  term,  and  reports  another  where  a  heedless  boy  threw  a 
dead,  bleeding  black  snake  around  his  sister's  neck,  and  in  spite  of  the  fact  that  she 
suffered  from  hysteric  syncope  and  convulsions  for  several  days,  the  pregnancy,  then 
at  four  months,  went  to  term.  The  child  was  not  "marked."  Excessive  coitus 
is  a  frequent  cause  of  abortion  in  the  newly  married.  Operations  come  under  the 
heading  of  trauma,  and,  unless  some  predisposition  exists,  usually  do  not  affect 
the  pregnancy.  The  author  has  removed  fibroids  from  the  pregnant  uterus,  in 
one  case  exposing  the  chorion,  and  has  amputated  the  cervix,  without  inciting  con- 
tractions. On  the  other  hand,  a  slight  operation  on  a  distant  organ  may  result  in 
miscarriage.  Ovarian  tumors  have  repeatedly  been  extirpated  safely  (66  per  cent, 
of  cases),  as  have  also  breast  and  other  tumors.  It  is  usually  the  shock  and  the 
sepsis  which  bring  on  the  alDortion.  Appendicitis  cases  are  especially  prone,  prob- 
ably because  of  the  infection.  Removal  of  both  ovaries  during  pregnancy  has 
brought  out  the  fact  that  they  are  not  needed  for  labor,  because  the  pregnancy  and 
parturition  have  so  often  proceeded  naturally.  It  seems  that  double  ovariotomy 
in  the  early  months  is  more  dangerous  to  gestation  than  later,  and  the  fact  is  ex- 
plained on  the  theory  that  the  secretion  of  the  corpus  luteum  is  necessary  for  the 
growth  of  the  ovum  and  uterus.  Criminal  traumatism,  for  example,  puncture  of 
the  ovum,  insertion  of  catheters,  etc.,  does  not  come  under  this  heading,  nor  does 
the  administration  of  drugs — sabine,  ergot,  cantharides,  which  have  to  be  given  in 
poisonous  doses  to  be  effective  in  emptying  the  uterus. 

Anesthesia  may  cause  death  of  the  fetus  if  too  prolonged  or  attended  by  great 
cyanosis,  as  is  the  continuous  nitrous  oxid  method.  Extraction  of  teeth  under 
brief  nitrous  oxid  gas  anesthesia  is  allowable,  a  dentist  in  this  city  who  has  ad- 
ministered it  over  12,000  times  having  assured  the  author  that  he  has  never  thus 
caused  an  al)ortion. 

It  is  necessary,  especially  in  medicolegal  cases,  to  decide  whether,  in  a  given 
instance,  the  accused  injury  really  caused  the  abortion,  and  this  point  can  seldom 
be  determined.  As  criteria  may  be  mentioned:  the  ovum  must  be  macroscopically 
and  microscopically  healthy,  and  show  no  other  cause  for  its  expulsion,  and  the 
death  of  the  ovum  and  its  expulsion  nmst  be  proved  to  have  occurred  very  shortly 
after  the  traumatism. 

Paternal  Causes. — Without  doubt  some  men  produce  a  sperma  which  is  too 
weak  to  give  the  ovum  the  necessary  generative  impulse.  Observation  of  many 
cases  of  male  sterility  has  convinced  the  author  of  the  truth  of  this  statement,  and 
examination  of  the  semen  in  these  instances  has  shown  a  paucity  of  spermatozoids, 
or  such  as  were  short-lived  or  inactive.     Syphilis,  tuberculosis,  general  paresis, 


ABORTION    AND    PREMATURE    LABOR 


419 


general  delnlity,  perhaps  fnjiii  excessive  coitus  or  from  alcoholism,  will  i)roduce 
such  conditions.     It  is  said  that  abortion  is  frecjuent  in  cows  that  were  covered  In' 
a  sexually  exhausted  hull.     A  man  with  a  purulent  di.scharge  in  tjic  scnicn  may 
cause  an  infection  in  the  uterus,  with  septic 
al)ortion.     Men  workers  in  lead,  j)hosphorus, 
mercury,  etc.,  are  not  .seldom  sterile.     It  is  a 
well-estal)lished  fact  that  x-ray  operators  l)e- 
come  sterile,  antl  it  would  be  interesting  to  dis- 
cover if  their  total  sterility  is  preceded  by  a 
series  of  abortions  in  their  wives. 

Premature  Idbor  is  i)roduced  by  the  same 
factors  that  bring  on  abortion,  but  syphilis 
plays  the  most  conmion  role  here,  it  being  esti- 
mated that  from  50  to  80  per  cent,  of  the  cases 
are  thus  caused.  Next  comes  nephritis,  witii 
placental  iiemorrhages  or  infarcts.  Twins  often 
come  prematurely  because  of  the  lack  of  room 
in  the  uterus,  and  any  tumor  in  the  abdomen 
which  is  large  enough  may  interfere  with  the 
development  of  the  uterus. 

Habitual  abortion  means  that  successive  pregnancies  are  interrupted,  usually 
at  the  same  period  of  development. 

Syphilis  is  usually  found  as  the  active  factor,  and   more  especially  in  mi.s- 
carriages  of  the  later  months.     Each  successive  abortion  occurs  at  a  lat<'r  p<'riod

in  the  later  inonths,  and  it  is  not  seldom  combined  with  uterine  displacement. 
Each  abortion  aggravates  the  endometritis,  a  "vicious  circle"  being  established. 

Nephritis,  diabetes,  or  constitutional  disorder  should  always  be  searched  for 
in  these  cases.  The  influence  of  the  father  may  not  be  forgotten.  He  may  not 
be  capable  of  procreating  a  viable  child.  Chronic  lead-poisoning  is  well  known  to 
have  such  an  effect,  and  probably  other  j^oisons  hav(^  similar  action.  Finally, 
there  is  a  class  of  cases  where  none  of  the  preceding  conditions  can  be  found,  yet 
the  woman  cannot  carry  a  child  through  to  term.     "With  improved  diagnosis — e.  g.,

Chapter  LXXV,  Induced  Labor.) 

Mechanism.— As  in  the  description  of  the  mechanism  of  labor,  in  abortion  we 
also  discuss  three  factors — the  powers,  the  passages,  and  the  passengers.  Uterine 
action  accomplishes  nearly  all  the  work  of  abortion  except  th(>  expulsion  of  the 
loosened  ovum  from  the  vagina,  which  the  abdominal  muscles  do.  The  bony 
passages  practically  never  come  into  consideration,  and  the  soft  parts  very  seldom, 
but  the  ovum  plays  an  important  part.  In  the  first  two  months  the  decidua  is 
thick,  vascular,  and  friable,  the  ovum  small,  soft,  and  compressible.  It  requires 
considerable  effort  by  the  uterus  to  separate  and  expel  the  former,  while  the  little 
ovum  slips  out  unobserved.  From  the  eighth  to  the  twentieth  week  the  placenta 
plays  the  main  role;   it  is  relatively  large,  separates  with  difficulty,  especially  from

the  utciiiK'  cornua,  and  suili  ninoval  is  usually  attended  by  profuse  hemorrhage. 
After  the  twentieth  week  tlie  fetus  is  the  most  important  passenger,  and  the  char- 
acter of  the  labor  resembles  more  and  more  that  at  term.  Separation  of  the  ovum 
occurs  in  the  spongy  layer  of  the  decidua,  antl  since  the  regressive  changes— the 
necrosis — have  not  progressed  far,  this  is  often  incomplete,  and  pieces  of  membraije 
or  placenta  are  likely  to  be  retained,  especially  in  the  tubal  corners.     One  may, 

therefore,   distinguish    three    fairly   well- 
defined  periods: 

First  Periofl.^ln  the  first  si.\  to 
eight  weeks  the  whole  ovum  is  usually 
born,  covered  by  the  (h*cidua,  and  it  is 
often  possible  to  reconstruct  the  condi- 
tions which  existed  in  tlie  uterus,  jis  in

with  portions  of  the  decidua.  Whenever  the  ovum  alone,  covered  l)y  the  shaggy 
coat  of  villi,  is  e.xjjelled,  one  nmst  conclude  that  the  decitUue  still  remain  in  the 
uterus,  and  will  require  another  effort  of  nature,  which  is  often  attended  by  pro- 
fu.se  hemorrhage.  In  a  few  cases  the  decitluir  ili.s.solve  anil  come  away  in  pieces  in 
the  lochia.  Shoukl  the  (>xternal  os,  as  in  j)rimii)ara',  offer  resistance  and  not  dilate, 
the  ovum  is  arrested  in  the  distended  cervix,  the  internal  os  cl<).«<ing.  This  was  called 
cervical  i>regnancy  by  Rokitansky,  but  a  better  term  is  cervical  abortion  (Fig.  37G). 
Simple  dilatation  of  the  constricted  os  is  sufficient  to  lilx*rate  the  ovum.  True 
ccrvical-i-<thmial  pregnancy  occurs  (Devraigne). 


422 


THE  PATHOLOGY  OF  PREGNANCY,  LABOR,  AND  THE  PUERPERIUM 


Second  Period. — Several  courses  are  taken  Ijy  the  abortive  process  during  the 
third  and  fourth  months.  First  the  whole  ovum  is  expelled — the  fetus  in  an  intact 
sac  and  a  large  part  of  the  decidua  covering  it.  This  may  be  called  the  typical 
course,  and  offers  the  best  prognosis  for  the  mother,  since  hemorrhage  is  usually 
mild,  interference  is  seldom  necessary,  and  the  remains  of  the  decidua  come  away 
Avith  the  lochia. 

Second,  the  membranes  rupture,  the  fetus  is  extruded,  the  cervix  closes,  and 
the  uterus  has  to  make  a  second  effort  to  expel  the  secundines  (Figs.  377  and  378). 
During  the  interval,  ownng  to  partial  separation  of  the  placenta,  hemorrhage  is 
profuse,  infection  of  the  placenta  may  occur,  and  interference  of  some  sort  is  usually 
necessary,  all  of  which  cause  a  worse  prognosis. 

Thirdly,  the  decidua  reflexa  and  the  chorion  break,  allowing  the  fetus  in  the  amni- 
otic sac  to  escape.  A  beautiful  specimen  is  here  shown  (Fig.  379).  The  accoucheur 
must  remember  that  the  uterus  still  contains  the  placenta,  chorion,  and  deciduse. 

In  abortion  the  uterine  contractions  act  the  same  as  in  labor,  and  dilatation  of 


Decidua

Fig.  380. — Beginning  Abortion  at  Sixth  Week. 


the  cervix  is  produced  in  the  same  way,  but,  owing  to  the  vascularity  of  the  decidua, 
hemorrhage  occurs  as  soon  as  the  contractions  begin,  because  the  decidua  loosens 
from  the  uterine  wall.  This  separation  l)egins  at  the  cervix,  proceeds  to  the  fundus 
(Fig.  380),  being  latest  in  the  tubal  corners.  Hemorrhages  into  the  decidua  and 
into  the  ovum  occur  and  aid  in  the  separation.  Upon  the  delivery  of  its  contents 
the  uterus  contracts  clown  on  itself  and  involution  begins.  This  is  slow^er  and  more 
likely  to  be  incomplete  after  abortion  than  after  labor  at  term.  After-pains  are 
sometimes  observed,  and  milk  not  rarely  appears  in  the  breasts.  In  abortion, 
even  before  the  fifth  month  of  gestation,  there  may  be  considerable  engorgement  of 
the  mammae. 

Abortion  after  the  fifth  month  is  really  a  labor  in  miniature,  and  needs  no 
further  description.  Breech  and  alniormal  presentations  are  commoner,  and  the 
whole  ovum  is  not  seldom  extruded  intact.  Expulsion  of  an  unliroken  ovum  is 
very  rare  in  the  last  months  of  pregnanc.y. 

Symptoms. — Clinically,  we  speak  of  three  forms  of  abortion, — threatened,  in 
progress  or  inevitable,  and  incomplete  abortion, — but  four  classic  symptoms    are 


•  ABORTION   AND    PREMATURE    LABOR  423 

present  with  all.  These  are:  uterine  pain,  uterine  liemorrhage,  softening  and 
(Ulataticm  of  the  cervix,  presentation  or  expulsion  of  all  or  parts  of  the  ovum. 

Threatened  abortion  is  indicated  by  a  bloody  discharge  from  the  uterus,  and 
sometimes  by  slight  drawing  paiiLS  in  the  back  and  pelvis,  similar  to  menstrual 
sensations.  The  blood  may  come  with  a  gush  or  ooze,  or  appear  as  a  brownish, 
flaky  mucus.  Piim  may  be  a  slight  symptom,  or  there  may  be  only  a  sen.se  of  weight 
in  the  pelvis.  On  vaginal  examination  the  uterus  may  feel  harder  than  nonnal, 
which  is  because  it  is  contracting.  Softening  and  dilatation  of  the  cervix  .seldom 
occur  in  threatened  abortion,  but  the  author  has  had  .several  ca.ses  where  the  cervix 
opened  so  that  the  finger  felt  the  lower  jiole  of  the  ovum,  and  yet,  after  subsidence 
of  the  .symptoms,  the  pregnancy  went  to  term.  An  abortion  may  appear  threaten- 
ing for  hours,  days,  or  even  months,  and  yet  pregnancy  go  to  full  term.  Again, 
suddenly,  profuse  hemorrhage  occurs,  pains  set  in,  and  the  process  becomes  in- 
evitable. 

Abortion  in  ])rogress  i)resents  the  same  symptoms,  but  the  hemorrhage  is 
greater,  the  pains  stronger  ami  more  regular,  resembling  tho.se  of  labor.  Softening 
antl  dilatation  of  the  cervix  proceed  from  above  downward,  and  the  shortening  of 
the  neck  of  the  womb  is  easily  followed  by  the  fmger  in  the  vaginal  fornices,  or,  when 
the  OS  is  opened,  inside  the  cervix,  at  which  time  also  the  ovum  or  the  edges  of  the 
separated  decidua  may  be  felt.  The  sjniiptoms  vary,  of  course,  with  the  mechan- 
ism of  the  abortion. 

If  the  whole  ovum  is  expelled  complete  in  one  effort  of  the  utenis,  the  hemor- 
rhage is  usually  moderate,  antl  the  pains  cea.se  as  soon  as  the  ovum  escapes  from  the 
cervix.  In  nuilti])arie,  because  of  the  open  cervix,  the  al)ortion  is  easier  and 
quicker  than  in  primipara).  If  the  decidua  remains,  it  is  dissolved  and  comes  away 
in  the  profuse  lochial  tlischarge,  sometimes  giving  it  an  offensive  odor,  but  seldom 
causing  fever,  though  it  may  leave  behind  a  chronic  thickening  of  the  endometrium. 

If  the  membranes  brc'uk,  the  fetus  escaping  naked  or  clothed  only  in  its  anmion, 
the  remainder  is  expelled  after  minutes  or  hours,  or,  becau.se  of  the  profuse  hemor- 
rhage which  usually  occurs,  or  the  fever  which  results  from  decomposition  of  the 
mass,  the  accoucheur  has  to  interfere  and  clean  out  the  uterus.  Hemorrhage  and 
pains  may  cease  in  the  interval,  during  which  time  the  case  is  called  one  of  incom- 
plete abortion. 

Incomplete  abortiun  means  that  the  process  has  started,  but  that  the  uterus  is 
not  entirely  rid  of  its  contents.  This  does  not  include  the  retention  in  the  uterus 
of  a  whole  but  dead  ovum — which  is  "missed  aliortion."  Incomplete  abortion  is 
a  dangerous  condition,  liecause  of  its  innnediate  and  remote  bad  sequels':  (a) 
The  cervix  partly  closes  after  the  escape  of  the  fetus,  and  the  placenta,  membranes, 
and  thick  decidua  gradually  break  do\Mi  and  are  discharged  in  the  lochia.  In 
these  cases  the  lochia  are  profuse  and  bloody,  sometimes  with  an  odor,  and  continue 
thus  until  the  la.st  vestige  is  removed.  Chronic  endometritis  is  almost  always  the 
final  result  of  such  a  process  (Fig.  381).  (6)  A  compli-te  interval  of  rest  may  Ije 
noted  until,  after  hours,  days,  or  even  months,  the  uterus  suddenly  exju'ls  its  con- 
tents, (c)  Decomposition  sets  in,  the  pieces  .soften  and  are  exfoliated,  a  layer  of 
granulations  separating  the  live  from  the  dead  tissue,  or  the  bacteria  lireak  through 
this  l)arrier,  sepsis  and  sometimes  d(>ath  resulting,  (d)  A  placental  polyp  is  formed, 
the  attached  portion  of  the  i)lacenta  being  well  nourished,  layers  of  fibrin  being 
deposited  antl  organi/.etl  on  the  outside  until  a  iKMlunculated  tumor  is  created, 
which  may  protrutle  from  the  cervix.  Syncjiioma  malignuin  is  not  .so  conmion 
in  these  cases  as  in  hydatid  moles. 

Diagnosis.— Tluratencfl  Ahoriion.—li  the  fact  of  normal  i)regnancy  is  known, 
uterine  hemorrhage  and  uterine  jxiins  signify  that  interrui)tion  of  gestation  threatens. 
It  is  not  easy  to  diagnose  early  jiregnancy  when  the  uterus  is  contract  nig.  because 
then  it  simulates  other  conditions,  for  example,  fibroid,  chronic  metritis,  ectopic 


424  THE    PATHOLOGY    OF    PREGNANCY,    LABOR,    AND    THE    Pn-:RPKR1UM 

ovum.  On  l)inianual  examination  the  large,  contracting  and  relaxing  uterus,  the 
beginning  softening  and  shortening  of  the  cervix,  and  the  bloody  discharge  show 
that  some  abnormal  process  is  going  on.  The  rule  is  to  treat  every  case  of  hemor- 
rhage, after  a  period  of  amenorrhea  occurring  in  a  woman  capable  of  reproduction," 
as  one  of  abortion. 

Differential  diagnosis  must  be  made  from  ectopic  gestation,  hemorrhage  from 
cervical  erosions  (not  rare),  varices  (very  rare),  hydrorrhoca  gravidarum,  and,  in 
addition,  all  the  conditions  not  associated  with  pregnancy,  for  example,  neoplasms 
and  malpositions.  AVhen  pregnancy  and  threatened  miscarriage  are  associated 
with  a  neoplasm,  truly  complicated  conditions  are  presented  for  differentiation. 

Inevitable  abortion  is  more  easil}'  determined — the  cervix  is  shortened  or  even 
dilated,  allowing  the  finger  to  feel  the  ovum,  and  pieces  of  the  decidua  or  of  the  ovum 
are  expelled;  hemorrhage  is  more  profuse,  the  bag  of  waters  ruptures,  and  painful 
uterine  contractions  are  usualh'  present.  These  signs  enable  us  to  saj'  that  an 
abortion  is  inevitable,  but  in  rare  instances  the  cervix  may  close,  the  hemorrhage 
ceasing,  and  pregnancy  goes  on  to  term.  The  discharge  of  decidua  is  usually  con- 
sidered positive  evidence  of  an  unavoidable  abortion,  but  the  author  had  one  case 
of  double  uterus  where  the  decidua  was  discharged  from  one  side,  the  other  being 
pregnant.  The  rupture  of  the  membranes  may  be  simulated  by  hydrorrha^a  gravi- 
darum, or  graviditas  exochorialis  (q.  v.  p.  518).  After  pregnane}^  is  determined 
the  cUfferential  diagnosis  in  abortion  has  to  deal  only  A\dth  ectopic  gestation,  and  the 
latter  must  always  be  taken  into  consideration.  Rarely  the  extrusion  of  a  fibroid 
or  a  poh^j  simulates  an  abortion. 

Incomplete  Abortion. — Is  the  uterus  empty?  Here  the  history  of  the  passage 
of  the  fetus  or  of  portions  of  the  placenta  may  be  useful,  but  unless  the  parts  have 
been  seen  by  competent  eyes,  the  information  must  be  questioned.  We  decide 
that  something  is  left  in  the  uterus  when  a  woman  who  has  had  an  abortion  con- 
tinues to  have  irregular  hemorrhages,  with  or  without  pains,  or  discharges  blood}' 
lochia,  with  occasional  clots  or  bits  of  tissue,  for  a  long  time.  Examination  will 
reveal  a  large,  soft,  subinvoluted  uterus,  which  sometimes  contracts,  with  a  succu- 
lent, patulous  cervix  through  which  the  finger  feels  shreds  of  decidua,  placenta,  or 
clots.  Microscopic  examination  of  discharged  or  cureted  pieces  of  tissue  maj'  show 
chorionic  villi.  In  some  cases  the  diagnosis  as  to  whether  the  uterus  is  empty  or 
not  may  be  impossible  without  a  curetage.  The  differential  diagnosis  must  be 
made  from  subinvolution,  endometritis  post-abortum,  ectopic  gestation,  fibroids, 
polypi,  and  occasionally  even  the  diagnosis  of  a  previously  existing  pregnancy 
comes  up.  Even  the  microscope  may  fail  to  settle  the  question.  The  cureted 
material  may  show  large  and  convoluted  uterine  glands  (Opitz),  but  these  are  not 
pathognomonic.  Hyaline  degeneration  of  the  uterine  vessels  gives  more  positive 
information. 

Prognosis. — Few  women  die  from  hemorrhage  during  abortion  because,  if 
the  bleeding  is  marked,  the  patient  faints  and  clotting  stops  the  small  blood-vessels. 
It  is  much  different  at  term.  If  the  hemorrhage  is  long  continued,  the  unavoidable 
small  loss  during  the  abortion  may  prove  fatal.  Death  is  usually  due  to  infection 
introduced  from  without,  for  example,  by  the  criminal  abortionist  or  by  the  phy- 
sician through  a  lack  of  asepsis.  It  must  be  remem})ered  that  coitus  can  cause 
infection  of  the  uterus,  which  results  in  abortion,  and  may  be  followed  by  fatal 
septicemia.  It  is  usual,  however,  in  cases  of  septic  abortion,  to  suppose  that  an 
abortionist  has  been  at  work.  If  the  uterus  has  been  perforated  and  sepsis  results, 
death  is  the  more  common  termination. 

The  prognosis  as  to  health  is  worse  than  after  la])or  at  full  term.  Involution 
is  slower,  lasting  several  months,  and  if  infection  has  occurred,  the  uterus  may  never 
be  normal  again,  })ut  remains  the  seat  of  chronic  metritis  and  endometritis.  Endo- 
metritis post-abortum  (Fig.  381),  characterized  by  the  prolonged  persistence  of

groups  of  decidual  cells  and  liyix*rtrophy  of  the  mucrjsa,  is  a  frequent  sequel  of 
al)ortion,  as  is  also  pelvic  jx-ritonitis  or  cellulitis.  In  after  years  women  who  liave 
had  one  or  several  abortioiLs  come  to  the  gj^necologist  complaining  of  l)ackache, 
sterility,  and  leukorrhea,  and  the  examination  shows  a  large,  hard  uterus.  hy|)er- 
trophied  cervix,  a  retroversion  or  retroflexion,  thickening  of  the  hroad  ligaments, 
antl  tenderness  along  the  sacro-uterine  folds.  Such  women  may  l»e  iiiv:iliil>  fur 
life  or  refjuire  capital  operations  in  order  to  be  cured. 

Treatment. — Threatened  Abortion. — It  is  inadvi.sal)le  to  examine  a  womuii 
threatened  l)y  abortion  Ix'cause  of  the  danger  of  aggravating  the  uterine  contrac- 
tions or  causing  hemorrhages  to  separate  more  of  the  decidua  and  <jvum;  therefore 
it  is  done  only  when  a  diagnosis  nmst  be  made,  and  then  with  the  greatest  gentle- 
ness. Rest  in  bed  is  the  l)est  treatment,  and  mijrphin  may  be  given  to  procure 
ai)Solute  quiet  of  patient  and  uterus.  Laudanum  in  2()-minim  dos<'s  [x-r  rectum 
every  four  hours  will  usually  sufhce,  but  it  may  Ijc  necessary  to  give  more,  watching

bleeding  recommences  every  time  the  patient  Ix'comes  at  all  active,  the  alwrtion 
is  in(witable,  a  mole  having  probably  been  formed.  One  may  not  allow  rt»peated 
hemorrhages  to  debilitate  the  woman.  The  author,  in  several  ciuses  of  placenta 
pra?via  near  term,  has  ol)tained  a  iii.>;tory  of  hemorrhages  in  early  pregnancy. 

Inevitable  Abortion. — Much  difterence  exists  in  the  treatment  of  al>ortion  in 
progress  as  practised  by  diflferent  authors,  and,  indeetl,  no  one  plan  will  apply  to 
all  cases.  A  method  that  is  i(h>al  for  the  first  twc'lve  weeks  must  l>e  modified  to- 
ward the  end  of  the  fifth  and  sixth  months,  and  again  difTerent  conditions  an'  pre- 
sented for  treatment,  as  may  l)e  seen  l>y  reverting  to  the  pages  on  the  Mechanism 
of  Abortion.  The  ideal  treatment  wouUl  l)e  "watchful  exjx'ctancy,"  meeting  the 
indications  as  they  arise,  similarly  to  our  contluct  during  labor,  but  exixnliency  may 
demand  more  active  interference.  The  patient  may  live  far  removed  from  meilical 
help,  or  the  physician  cannot  remain  at  the  Ix'dside  during  tin-  prolonged  ccmr^' 
sometimes  days — of  some  abortions;  moreover,  nothing  would  Ix,*  gained  by  it, 
since  the  child  is  alwavs  lost. 


426 


THE  PATHOLOGY  OF  PREGNANCY,  LABOR,  AND  THE  PUERPERIUM 


If  the  hemorrhage  is  continuous,  whether  profuse  or  not,  the  cervix  and  vagina 
are  to  be  tamponed.  Objections  to  the  tampon  on  the  score  of  its  inviting  sepsis, 
being  painful,  and  causing  retention  of  urine  are  of  little  weight.  The  author 
treats,  indirectly,  through  the  Chicago  Lying-in  Hospital  Dispensary',  hundreds 
of  abortions  each  3'ear,  and  jiractises  the  treatment  here  recommended  with  uni- 
form success. 

Technic. — Everything  needed  is  arranged  near  the  binl  or  table,  so  that  the  operator,  who 
usually  has  little  assistance,  may  wait  on  himself.  The  patient  is  asked  to  emptj'  the  bladder, 
or  she  is  catheterized  before  the  tampon  is  inserted.  The  genital  region  is  shaved,  as  for  any 
gATieeologic  operation,  scrubbed  with  soap  and  warm  water,  and  then  thoroughly  washed  with 
1:1000  bichlorid.  Lately,  painting  with  tincture  of  iodin  is  recommended.  The  accoucheur 
sterihzes  his  hands,  draws  on  sterile  rubber  gloves,  and  washes  the  vagina  and  cer^^x  gently  but 
thoroughly  with  1  per  cent,  h'sol  solution.  For  the  tamponade  the  dorsal,  Sims'  lateral,  or  knee- 
chest  position  may  be  used:  the  former  is  the  usual,  the  last  a  very  good  one  if  short  of  help. 
\Mienever  possible  the  author  uses  a  table  for  such  work.  A  perineal  retractor,  long  dressing 
forceps,  scissors,  and  catheter  are  the  only  instruments  needed.     First  the  cervix  is  packed  with 


Fig.  382. — Cehvix  Packed  with  Gauze  and  Vagina  with  Cotton  in  the  Treatment  of  Abortion. 


a  strip  of  narrow,  plain,  sterilized  gauze,  which  extends  up  into  the  uterus  (Fig.  382).  Then 
the  vault  of  the  vagina  is  filled  with  pieces  of  dry,  thoroughly  sterile  cotton,  or  the  same,  squeezed 
dry  out  of  a  0..5  per  cent,  lysol  solution.  After  one  layer  of  cotton  is  placed  around  the  cervix 
it  is  firmly  tamped  into  the  fornices  and  the  second  layer  then  put  in,  the  packing  and  tamping 
into  place  being  executed  by  two  fingers.  The  upper  two-thirds  of  the  vagina  are  thus  tightly 
and  evenly  plugged,  but  the  lower  third  needs  only  a  loose  pack,  which  is  good  too  because  it 
reUeves  the  urethra  from  pressure.  A  gauze  pad  is  laid  against  the  AOiIva,  a  T-binder  applied,  mak- 
ing moderate  counterpressure,  and  the  patient  put  to  bed.  A  properly  apphed  tampon  will  stop 
hemorrhage  absolutely,  and  every  practitioner  ought  to  be  able  to  insert  it.  Often  the  author 
has  removed  a  "tampon"  con.sisting  of  three  to  six  lumps  of  cotton  pulled  off  a  roll  and  placed 
in  the  vagina,  without  any  attempt  at  aseptic  preparation  of  the  parts. 

The  tampon  is  allowed  to  remain  for  from  sixteen  to  twentj^-four  hours, 
and  is  not  removed,  even  if  the  temperature  rises.  During  the  interval  pains  almost 
always  supervene,  which  means  that  the  uterus  is  trying  to  expel  its  contents.  No 
medicine  should  be  given  to  allay  this  pain,  nor  does  the  author  use  ergot,  which  is 
recommended  by  some.  Often  the  pains  cease  suddenly,  and  one  surmises  that  the 
uterus  has  emptied  itself  above  the  tampon.  A  convenient  hour  is  selected  for  the 
removal  of  the  tampon,  but  preparations  should  have  been  made  for  curetage  under 


ABORTION    AND    PREMATLRE    LABOR 


427 


anesthesia  if  this  should  Ije  fountl  necessary.     Often  the  entire  ovum  is  found  lying 
on  the  tampon,  its  separation  having  been  aided  by  the  damming  back  of  the  blood, 


Fio.  3.>;i. — Ai  riioii'a    I  tkkink  (."itiet.

and   its  expulsion   having  l^een   accomplished   by   the  uterine   contractions.     All 
tiiat  is  needed  in  such  cases  is  to  go  over  the  uterus  lightly  with  a  half-sharp  curet, 


Fio.  3M. — Ccrbtage  wrni  Finder. 


to  make  certain  that   pieces  are  not   retained — especially  in  the  tubal  comers. 
Some  authors  advise  against  this  curetage,  but  the  writer  cKk's  it  in  all  cases,  lie- 


428 


THE  PATHOLOGY  OF  PREGNANCY,  LABOR,  AND  THE  PUERPERIUM 


lieving  that  the  patients  make  quicker  and  completer  recoveries  when  the  uterus 
is  left  absolutely  smooth  and  clean.  Without  doubt  much  damage  is  caused  by  the 
curet  in  the  hands  of  an  unskilful  practitioner,  but  this  is  no  reason  for  condemning 
it — rather  should  we  seek  to  qualify  the  practitioner  to  use  all  safe  means  for  the 
patient's  benefit. 

If,  when  the  packing  is  removed,  the  cervix  be  found  still  closed,  it  is  best  to 
tampon  again  and  empty  the  uterus  on  the  following  day.  Forcible  dilatation  of  the 
cervix  is  an  unsafe  operation,  and  one  the  author  avoids  whenever  possible. 

For  cleaning  the  uterus  the  finger  excels  all  instruments,  and  should  be  used  to 
dilate  the  cervix,  if  this  is  needed;  but  sometimes  it  may  be  necessary  to  resort  to  steel 
dilators,  either  of  the  glove-stretcher  pattern,  a  Goodell  or  Bossi,  or  the  bougies  of 


Fig.  385. — Squeezing  out  the  Loosened  Contents  of  the  Uterus  by  Bimanual  Compression. 


Hegar.  All  are  dangerous,  and  even  in  the  hands  of  experts  have  time  and  again 
ruptured  the  uterus,  with  fatal  results.  Some  authors  still  recommend  laminaria 
tents,  but  the  writer,  in  all  his  experience,  has  never  used  one.  Packing  the  uterus 
and  cervix  with  gauze  softens  and  dilates  the  parts  sufficiently  to  allow  all  necessary 
operating. 

When  the  cervix  is  open  to  admit  one  finger,  the  uterus  is  to  be  emptied,  pref- 
erably under  ether  anesthesia.  If  the  ovum  protrudes  through  the  os,  it  may  be 
grasped  by  the  fingers  or  a  polypus  forceps  and  withdrawn  from  the  uterus;  then 
the  uterine  cavity  is  revised  bj^  the  finger,  and  rough  places  smoothed  over  with  the 
curet  (Fig.  383).  If  the  ovum  is  still  in  the  uterus,  it  is  completely  loosened  by  the 
finger  aided  by  the  outside  hand  (Fig.  384).  After  it  is  freed  from  all  its  attach- 
ments, combined  pressure  by  the  two  hands  may  squeeze  it  out  into  the  vagina

grasped  In'  an  ovum  forceps  (Figs.  380  and  387)  and  gently  withdrawn.  Exces.»<ive 
care  is  to  be  observed,  first,  to  make  sure  that  the  ovum  is  really  floating  free  in  the 
cavity  of  the  uterus,  and,  second,  to  be  absolutely  certain  that  the  forceps  do  not 
bite  into  the  uterine  wall.  The  latter  accident  has  happene»l  repeatedly  and  the 
operator  been  stagg<'rcd  to  find  omentum  or  intestine  in  the  grasp  of  the  instrument. 
This  accident  may  be  avoided  by  first  separating  the  ovum  by  the  finger,  inserting 
the  forcei)S  under  the  guidance  of  the  finger,  and  then  rotating  the  blades  of  the

forceps  during  the  act  of  closing  them,  a  little  trick  which  the  author  has  attempted 
to  illustrate  in  Fig.  389;  on  the  least  suspicion  that  more  resistance  is  encountered 
than  is  to  be  expected  the  instrument  must  be  released.  After  the  main  portion  of 
the  ovum  is  removed,  the  fingi'r  is  inserted  and  the  enilometrium  .scraped  clean  and 
smooth.  Since  rubber  gloves  are  ased,  we  lose  the  assistance  of  the  hnger-nail. 
If  the  cervix  is  large  enough,  the  finger  is  covered  with  gauze,  and  thus  the  thick 
decidua  may  be  rubbed  off,  but  usually  in  early  abortions  it  is  necessary  to  use  the 
curet.  In  using  th(>  curet  th<'  uterus  is  to  be  pulled  down  by  means  of  a  vul.M-llum 
forceps  (Fig.  392).     This  straightens  the  canal  and  brings  the  organ  within  n-acli.

plishod,  and  dilatation  of  tlic  cervix  to  admit  one  finger  is  usually  sufficient.  After 
this  period  the  fetus  is  larger  and  more  dilatation  is  reciuired,  for  which  reason  the 
tampon  should  he  used  to  jirocure  it,  or  a  small  colpeurynter  is  employed.  Again 
the  author  warns  against  rai)id  dilatation  with  steel  divulsors.  If,  at  the  time  of 
operation,  the  cervix  is  not  large  encnigh  t(j  deliver  the  fetus  entire,  it  may  he  de- 
livered after  morcellement.  A\'ith  the  fingers  in  the  uterus  a  foot  is  drawn  down, 
and  with  scissors  the  body  is  split  along  the  spine,  grasping  successively  higher  por- 
tions of  the  trunk.  Heed  is  j)aid  to  the  sharp  little  hones,  and  all  attention  con- 
centrated on  preventing  injury  to  the  cervix.  With  a  sharjj-pcjinted  scis.sors  the 
skull  is  punctured,  and  the  head  sfjueezed  flat  with  the  ovum  forceps  and  delivered. 
If,  inadvertently,  the  trunk  is  i)ulle(l  olT  the  head,  the  oj)erat(jr  may  have  not  a  little 
trouble  in  engaging  the  round,  floating  body  in  the  grasp  of  the  onuuj  f(jrceps.

Fig.  387  shows  a  good  instrument  to  use  in  this  emergency — an  old-fashioned  stone 
forceps;  the  i)lades  are  openeil  in  the  uterus,  and  the  head  pressed  into  them  by  the 
abdominal  hand.  A  better  way,  in  difficult  ca.^es,  when  the  cervix  is  very  long, 
thick,  and  hard,  is  to  nuike  a  transverse  incision  in  the  vagina  at  its  junction  with 
the  cervix,  push  the  bhuUler  from  the  anterior  wall,  and  incise  the  uterus,  as  in 
vaginal  cesarean  s(>ction.  Any  one  who  has  attempted  to  remove  a  five  months' 
fetus  through  a  long,  hard,  closed  cervix  will  appreciate  its  difficulties.

especially  true  in  septic  cases.     The  placental  site  feels  nnif^h,  and  the  fissures  in  it  allow  the 
finger  or  curet  to  enter  the  mucosa  (Fig.  395),  giving  the  impression  that  there  is   a   piece  of 

placenta  still  adherent.  Thus  the  o{)erator  is  mis- 
guided, and  soon  ])erforates  into  the  ])eritoneal 
cavity.  If  the  utiTUs  is  soft,  the  curet  may  be 
punched  through  its  wall,  especially  if  the  oper- 
ator uses  force  on  the  upstroke.  Branched  or 
bougie  dilators  may  rupture  the  cervi.x  and  lower 
uterine  segment,  and  the  polypus  or  ovum  forceps 
may  grasp  and  tear  off  the  inverted  uterine  wall,  as 
in  Fig.  390.  All  these  accidents  may  be  avoided  by 
using  the  fingers,  where  ])ossible,  and  by  observance 
of  the  rules  for  their  j)rev(>ntion.  If  a  perforation 
occurs,  the  cas(^  immediately  assumes  a  serious 
aspect  and  requires  most  careful  consideration. 
Should  there  be  the  least  suspicion  of  injur}'  to 
the  bowel  or  the  omentum,  the  belly  is  to  be  opened 
immediately,  the  damage,  if  anj',  repaired,  the 
uterus  opened,  cleansed,  and  sutured,  after  which 
it  is  drained  through  the  vagina.  In  the  assurance 
that  the  viscera  have  not  been  hurt,  vaginal  anter- 
ior hysterotomy  is  to  be  performed,  the  uterine 
cavity  emptied,  the  rent  lightly  packed  with 
gauze,  leading  this  into  the  vagina,  and  then  the 
uterus  closed  as  after  vaginal  cesarean  section. 
This  method  is  safer  than  to  attempt  to  curet  the 
uterus  and  to  try  to  avoid  the  site  of  injury.  There 
is  always  the  danger  of  enlarging  the  perforation 
and  of  injuring  the  bowel  in  thus  operating  blindly. 
A  single  perforation  of  the  uterus  may  be  treated 
by  packing,  though  the  accoucheur  always  takes  a 
little  risk  here  if  the  finger  cannot  confirm  the  diag- 
nosis of  the  extent  of  the  damage. 

In  clean  cases  the  above  treatment  will  almost 
always  save  the  patient,  but  if  the  abortion  was  septic,  especially  if  the  infection  was  streptococcic, 
a  uterine  perforation  is  usually  fatal.  For  this  reason  immediate  extirpation  of  the  uterus  is  the 
best  treatment  for  such  an  accident — vaginally,  if  there  is  positivelj'  no  injury  to  the  bowel; 
otherwise  abdominally,  with  the 
needed  repair  of  the  viscera.  Should 
the  radical  operation  be  impossible, 
the  contents  of  the  uterus  must  be 
removed,  after  vaginal  hysterotomy, 
if  necessary;  then  the  uterus  and  the 
pehns  are  to  be  broadly  drained. 
After-treatment  consists  of  sitting 
the  patient  up  in  bed  to  insure  drain- 
age and  the  free  administration  of 
saline  solution  per  rectum.  The 
uterine  gauze  is  removed  in  thirty- 
six  hours;  that  in  the  culdesac  of 
Douglas  in  sixty  hours,  being  re- 
placed or  not,  depending  on  the 
patient's  condition.  It  is  wise  to 
discover,  before  treating  an  abortion 
case,  whether  any  one  has  passed  in- 
struments into  the  uterus,  because 
a  perforation  may  have  thus  been 
made,  which  later  is  laid  at  the  door 
of  the  honest  practitioner. 

Acute  Dilatation  of  the  Uterus. 
— Occasionally,  while  cureting  a 
uterus,  the  curet  slips  far  beyond  a 
normal  depth  and  the  operator  fears 
he  has  perforated  the  organ.  Ex- 
amination shows  no  pimcture,  and 
the  conclusion  must  be  drawn  that 
the  uterus  dilated  suddenly,  or  that 
the  instrument  passed  into  the  tube. 
The  author  has  observed  two  cases 

where  the  uterus  seemed  to  dilate  enormously  during  early  pregnancy,  ;i  ]>henomenon  also  ob- 
served by  Biittner,  of  Geneva. 

Incomplete  Operation. — Rarc^ly  the  accoucheur  may  be  unable  to  empty  the  uterus  com- 
pletely, which  occurs  more  commonly  after  the  fourth  month.  The  cervix  offers  miexpcn-ted  re- 
sistance, or  the  morcellation  of  the  fetus  is  impossible  and  preparations  have  not  been  made  for

a  ruttiriK  opcnition.  Whctlicr  tin-  case  is  clean  or  not,  the  hkkIo  of  proccvlurc  here  is  to  pack  the 
uterus  lirnily  with  \vc;ik  iodin  nauze.  Usually  pains  start  up,  ami  after  twentj'-four  hours, 
on  rcinovin«  the  jjackinti,  tin-  remnants  of  the  ovum  crjine  with  it.  UuriiiK  the  ojx-ration  of  mor- 
cellation  the  pieces  of  fetus,  placenta,  etc.,  ilelivered  should  he  spread  on  a  towel  and  titled  to- 
gether, thus  removing  all  douht  as  to  how  much  remains  in  the  uterus. 

lOxtra-uterine  pregiiancy  nmst  be  thought  of  bef<jre  every  cun-tage,  and  a  careful  bimanual 
examination  made  to  eliminate  it.  Such  an  operation  on  the  uteru.s  would  almost  surely 
caus(*  rupture  of  the  sjic.  Indeed,  it  is  nece.ssiiry  to  make  a  careful  bimaimal  e.vatnination  as  a 
routine  practice  before  operating,  to  di.scover  the  existence  of  adnexa  tumors,  for  j-xample,  preg- 
nancy, pus-tubes,  appendicitis,  and  to  deternune  the  position  and  mobility  of  the  uterus. 

Incomplete  Abortion. — After  the  diagnosis  of  material  remaining  in  the  uterus 
ha.s  heen  made,  the  hest  treatment  is  its  removal,  witlujut  trii.sting  entirely  tonature's 
elTort.s.  Two  courses  are  atlvised:  one,  inmu-diate  ciirelage,  dilating  the  uterus 
if  necessary;  the  other,  packing  the  uterine  cavity,  tampon  of  the  vagina,  and  wait- 
ing for  the  contractions  of  the  uterus  to  expel  its  contents.  The  author  recommends 
the  latter  course  for  general  practice.  If  the  patient  is  in  a  good  maternity  hospital, 
and  on  the  first  examination  the  cervix  is  found  soft  and  open  for  the  finger,  the 
uterus  may  be  cleared  of  its  contents  at  once  and  the  case  thus  definitively  emleil. 
After  the  tamponade  of  the  uterovaginal  tract  the  treatment  is  the  same  as  that  given 
under  Abortion  in  Progress. 

Septic  Abortion. — When  the  cavity  of  an  aborting  uterus  becomes  infected,  we 
speak  of  septic  abortion.  ]\Iost  of  such  cases  are  the  result  of  criminal  interference 
by  midwives  or  other  abortionists,  but  sometimes  the  woman  herself  jjasses  instru- 
ments into  the  cervix  or  injects  fluids  of  some  kind — usually  irritating  antiseptics. 
Thomas  tells  of  a  phN'sician's  wife  who  had  pushed  an  umbrella  rib  up  through  her 
diaphragm.  The  author  had  a  case  where  the  belly  was  fountl  full  of  milk,  whi<-h 
the  unfortunate  woman  had  injectetl  into  the  uterus.  The  iliagnosis  in  such  in- 
stances is  very  difficult,  because  the  patient  generally  denies  the  facts.  A  thorough 
physical  examination  of  the  whole  body  will  not  fail  to  locate  the  trouble  in  the 
genitalia,  and  then  the  demonstration  of  gestation  will  clinch  the  diagnosis.  The 
signs  aiul  sNinptoms  of  infection  will  l)e  considered  under  Puerperal  Fever. 

Schottmiiller,  in  100  cases  of  septic  abort  if)n.  found  the  following  bacteria: 

Streptococcus  putridus 29  times 

Staphylococcus 26 

Bacterium  coli 19 

Streptococcus  vaginalis S     '" 

Streptococcus  erysipclatis 6      " 

Bacterium  phlegmonis  emphysematosic  (Friinkel) .5      " 

Bacterium  coli  hemolyticum once 

Gonococcus " 

Streptococcus  viriilans .  .  " 

Bacillus  paratj'phus  B " 

The  Streptococcus  putridus  could  be  frequently  demonstrated  in  the  bloo<l,  even  in  those 
cases  where  th(^  process  w:\s  believed,  from  clinical  manifestations,  to  be  purely  local,  i.  <.,  a 
sapremia,  and  it  also  caused  violent  salpingitis  and  fatal  peritonitis. 

Formerly  the  accepted  treatment  for  septic  al)ortion  wa.s  the  immediate  empty- 
ing ofthcuterus,  dilating  the  cervix,  if  necessary,  but  I  am  now  pursuing  a  more 
expectant  course,  trusting  much  to  nature,  it  having  l^een  shown  that  the  inevit- 
able traumatism  is  often  fatal,  a  superficial  and  not  dangerous  infection  being 
converted  into  one  with  strongly  invasive  characters.  A  chill  and  high  fever  often 
follow  curetage  in  septic  abortion,  being  the  expression  of  the  tUHuling  of  the  sys- 
tem with  l)acteria  and  toxins.  In  cases  of  putrid  infection  the  temiK-rature  soon 
becomes  normal,  but  if  the  pus  cocci  are  present,  esixn-ially  an  invasive  strepto- 
coccus, the  woman  b(>comes  very  sick  and  recovers,  if  at  all,  nnich  more  slowly.  If 
we  knew  that  this  was  the  kind  of  infection  we  had  to  deal  with,  extirpation  of  the 
uterus  would  be  better  treatment  than  curetage.  but,  unfortimately.  science  does 
not  yet  permit  us  to  prove  this  in  time  for  action.  (See  Pueri^eral  Infection.) 
Parametritis,  perimetritis,  even  general  sepsis  oftener  follow  such  dra.'stic  inter- 
ference than  the  slower  methods.  The  author  is  not  alone  in  this  matter.  Ries  and

43-i      THE  PATHOLOGY  OF  PREGNANCY,  LABOR,  AND  THE  PUERPERIUM 

Watkins,  of  Chicago,  and  Winter,  of  Konigsberg,  recently  published  the  same  views. 
Veterinarians  have  long  been  aware  of  the  dangers  of  forcibly  cleaning  out  the 
septic  uterus. 

When  the  diagnosis  of  septic  abortion  is  made,  a  careful  history  as  to  its  cause 
is  obtained.  The  physician  must  explain  to  the  ])atient  the  danger  of  making  false 
statements  or  of  hiding  th(>  truth.  If  there  is  reason  to  l)elieve  that  she  or  an  abor- 
tionist has  passed  an  instrument  through  the  uterus,  and  if  there  are  symptoms  of 
peritonitis,  the  belly  had  better  be  opened  at  once.  Next  to  be  decided  is  whether 
there  is  anything  in  the  uterus.  The  history,  uterine  contractions,  continued  ])leed- 
ing,  and  the  findings  on  vaginal  examination,  the  large  uterus,  open  cervix,  and 
protruding  masses  will  settle  this  point.     In  cases  of  doubt  leave  the  uterus  alone. 

Where  the  uterus  is  full  of  decomposing  ovular  and  blood  masses,  bleeding 
usually  commands  their  removal,  and  this  must  be  done  in  the  gentlest  possible 
manner.  The  uterus  and  vagina  are  evenly  filled  with  sterile  gauze  by  means  of 
the  tubular  packer,  without  anesthesia.  At  the  end  of  twcntj^-four  hours  the  gauze 
is  removed,  and  often  the  contents  of  the  uterus  come  with  it.  If  not,  the  uterus 
may  be  tamponed  again.  Pituitrin  and  ergot  may  be  administered.  Onl}-  after 
the  septic  symptoms  have  subsided  may  the  placental  masses  be  removed  by  the 
finger  or  ovum  forceps.  Before  and  after  uterine  interference  in  septic  cases  the 
author  uses  a  douche  of  1  per  cent,  lysol  solution,  and  when  the  uterus  is  emptied, 
a  light  drain  of  gauze  is  left  in  for  from  ten  to  twelve  hours.  This  absorbs  the 
blood,  and,  when  removed,  brings  away  shreds  of  membrane,  leaving  the  uterus 
perfectly  dry.  In  septic  cases  the  finger  should  supplant  the  curet.  After  the 
primary-  cleansing  of  the  uterine  cavity  no  local  interference  with  the  reparative 
processes  of  nature  is  allowed  unless  an  al^scess  forms  or  other  surgical  indica- 
tions arise. 

In  the  absence  of  hemorrhage  the  expulsion  of  the  retained  fragments  is  to  be 
left  to  nature,  unless  very  special  reasons  exist  for  entering  the  uterus. 

Summary  of  the  Treatment  of  Abortion. — 1.  Threatened  abortion — Rest  in  bed 
and  opiates. 

2.  Abortion  in  progress — (a)  If  the  hemorrhage  is  marked,  pack  the  cervix  with 
gauze  and  the  vagina  with  cotton;  (6)  next  daj-  remove  the  tampon;  if  the  ovum  is 
delivered,  empty  the  uterus  with  finger  and  curet;  (c)  if  the  ovum  is  not  delivered 
and  the  cervix  fulh'  dilated,  remove  the  ovum  by  traction,  expression,  or  by  the  fingers, 
then  revise  the  uterus  with  finger;    (rf)  if  the  cervix  is  still  closed,  tampon  again. 

3.  Incomplete  abortion:  (a)  If  the  cervix  is  open,  empty  the  uterus  at  once; 
(b)  if  closed,  pack  the  uterine  cavity  with  gauze  and  the  vagina  with  cotton;  (c) 
next  day  remove  the  same  and  treat  as  No.  2. 

4.  Septic  abortion:  Treat  as  abortion  in  progress  with  hemorrhage,  procure 
complete  dilatation  by  packing,  and  drain  the  uterus  with  gauze;  avoid  the  curet. 

Habitual  Abortion. — Even  if  the  cause  can  be  found,  it  is  not  always  possible 
to  prevent  the  frequent  recurrence  of  abortion.  Endometritis,  retroflexion,  lacera- 
tion of  the  cervix,  and,  in  the  later  months  of  this  period,  syphilis,  are  the  most 
common  causes,  and,  if  successfully  cured  before  pregnancy,  may  allow  the  same  to 
be  completed.  Treatment  of  the  husband  in  some  instances  is  successful.  During 
gestation  only  syphilis  and  the  displacements  may  be  treated.  Rest  in  bed  during 
the  time  when  the  abortions  usually  occur,  and  at  the  times  of  the  customary  men- 
strual periods,  care  in  exercise,  abstention  from  coitus,  and  alterative  tonics — 
iron,  arsenic,  and  mercury — are  recommended.  On  theoretic  grounds,  corpus 
luteum  extract  might  be  useful. 

Changes  in  the  Ovum  After  the  Death  of  the  Fetus. — If  ihp  fetus  dies  in  the  early  weeks, 
the  chorion  and  the  decidua,  which  are  nourished  l)y  inalernal  l)lood,  may  go  on  growing,  but 
hemorrhages — apoplexies — are  very  common  in  the  decidua,  and  one  causes  another  until  tlie 
whole  periphery  of  the  ovum  is  invaded.  The  caxity  of  the  amnion  is  crowded  togeth(»r,  or  the 
blood  may,  in  rare  cases,  break  into  the  ovum  it.s(>lf.  This  is  called  a  "blood  mole"  (Fig.  390). 
Or  the  membranes  may  undergo  an  eccentric  hypertrophy  and  the  amniotic  cavity  grows  larger,

ealiecl  a  "fleshy  mole."  These  moles  usually  eause  repeated  greater  or  smaller  hemorrluiges  until 
finally  the  uterus  e.vpels  them  or  the  attendant  interfere.s. 

Hreus  (h'-scrihed  a  mole  in  which  the  amni(jtic  cavity  was  invad(xl  hy  smaller  or  larger  sul>- 
chorial  liemorrhages,  calling  it  a  tuheroas  subchorial  hemalonia.  Taussig  guve  it  the  name  of 
hematoma  mole  (Fig.  'Ml).  In  .some  unexijlaine<l  citses  the  phu-enta  may  continue  to  grow  after 
fetal  death,  and  an  enlargement  of  the  amniotic  cavity  has  also  l>e<-n  f(jund  hy  the  author. 

Later  in  pregnancy,  after  the  fetus  ha.s  attaiiu-d  .some  hulk,  changes  similar  to  those  of  a  dead 
ectopic  fetus  are  olwerved,  and  it  may  he  days,  montks,  or  years  before  the-  ovum  is  e.\fM'lle<i. 
These  are  ca.scs  of  "inis.sed  abortion."  a  term  first  u.sed  by  Oldham.  (1)  Maceration  is  most  conj- 
n)on,  the  fetus  imbibing  the  dissolved  blood-pigments — fotus  sanguinoh-ntis.  Its  ti.ssu«-s  are  .«oft, 
the  joints  loo.se,  especially  the  cranial,  the  brain  is  liciuefied,  the  skin  flabby,  the  e[)idermis  missing 
in  large  patches,  exposing  the  deep-red  corium,  and  thec(»rd  thick  ami  bloo<"l-staine<l;  the  placenta, 
which  may  go  on  growing  even  after  fetal  death  anil  may  attain  remarkable  siz<'.  is  large,  pale, 
and  .soft.  It  is  imj)ossible  to  decide  from  the.se  changes  how  long  the  fetas  has  be«'n  tlead,  U'caU-se 
sometimes,  even  after  many  days,  little  alteration  of  the  tissues  is  found,  and  again  the  disintegra- 
tion occins  rapidly— due  to  the  presence  of  enzymes  in  the  li(iuor  anmii.  (2)  Mummification 
occurs  more  rarely.  The  fetus  dries  up,  becomes  leathery,  and  may  give  considerable  trouble  in 
removal  by  morcellatioii.  The  li(juor 
umtiii  is  al)sorbed,  or  represented  by 
u  thick  yellow  or  greenish  paste,  the 
placenta  being  u  tough  white  in- 
farct ed  nuus.s.  This  condition  occurs 
oftenest  with  twins  when  one  of  the 
fetu-ses  dies  in  the  early  months  and 
i.s  pre.s.sed  against  the  uterine  wall  by 
the  growing  twin — fcetus  compressu.- 
or  papyraceus  ( Fig.  422  on  p.  4G."> 
shows  the  condition).  (3)  Litho- 
p)edion  formation.  This  is  excep- 
tional in  the  uteru.s  it.self.  (4)  .Sep- 
tic infection  of  the  uterine  contents  is 
common  in  orilinary  but  not  in  cases 
of  "mis.sed  abortion,"  imle.ss  instru- 
mental interference  has  been  prac- 
tised or  coitus  has  been  coiitiiuieil. 
Even  after  months  septic  infection 
may  occur. 

Missed  abortion  seldom  gives 
niarketl  symptoms.  The  sympa- 
thetic .symptoms  of  pregnancy,  nau- 
sea,etc. .usually  cease  with  the  death 
of  the  fetus;  the  breast  and  pelvic 
organs  retrogress;  the  uterus  stops 
growing  and  a.ssunies  a  jM-culiar  noi^- 
resilient  consistence,  with  freciuent 
contractions  (minus  paim.  and  a 
brownish,  sometimes  fetid,  discharge 
appears.  Cieneral  .symptoms  of 
malaise,  lo.ss  of  flesh,  anorexia,  chilli- 
ness, and  afternoon  temperature  are 

due  to  begiiniing  decomposition  of  the  ovum  and  demand  interference.  The  diagnasLs  of  mi.s.sod 
abortion  is  made  on  two  bimaiuia!  examinations  with  an  interval  of  a  month  between  them.  The 
uterus  grows  smaller,  not  larger,  harder,  not  .>iofter.  It  is  best  to  wait  two  months  before  chx-iding 
that  the  ovum  is  deatl,  beiause  .■sometimes,  normally,  the  uterus  does  not  grow  regularly,  and  again 
a  hydatitl  mole  may  cau.se  an  excessive  enlargement  of  tlu-  uterine  tumor.  From  the  history  one 
learns  that  the  periods  have  been  absent  for  several  months,  that  a  slight  blee«ling.  with  or  with- 
out pains,  had  occurretl.  since  which  time  the  symptoms  of  pregnani-y  had  retrogr«'s.<e«l. 

These  points  are  very  aseful  in  the  ditTerential  diagnosis  which  Ikls  to  be  made  from  fibroid. 
After  one  is  a.ssured  that  the  ovum  is  dead,  the  uterus  hail  best  be  emptie«l.  The  indolence  of  the 
uterus  in  such  ca.ses  is  sometimes  remarkable,  the  author  having  not  .succchiUmI  in  days  of  etTort  in 
getting  reg)ilar  pains  start eil.  and  having  finally  to  inci.-^e  the  cervix  to  be  able  to  clean  out  the  uterine 
cavity.     Hemorrhage  after  the  curetage  is  the  rule,  and  a  firm  uterine  tampon  is  usually  n-tiuire*!. 

Di.-i.solution  of  a  very  early  fetus  and  resorption,  with  regeneration  of  the  ihvidua  without  ex- 
foliation of  the  .same.  h:us  bin-n  report efl,  but  such  an  occurrence  is  extremely  rare,  and  in  all  prol)a- 
bility  often  is  an  error  of  diagnosis,  the  fetal  and  decidual  structun's  having  escajxil  unob-M-rvwl. 

Medicolegal  Aspects  of  Abortion. — When  the  accoucheur  Ikls  to  deal  with  a  criminal 
abortion,  he  should  always  lia\e  iiiunsel.  or  put  the  patient  in  a  hospital,  avoiding  all  apix-anince 
of  secrecy.  This  would  excite  the  suspicion  of  connivance  at  the  de<i|.  While  it  is  impossible  to 
do  so.  it  would  be  best  for  every  one  concernivl  if  every  ca.se  of  criminal  al>ort ion  were  re|>ortc-vl 
to  the  police  autlu)rities.  Certainly  if  the  patient  dies  the  coroner  nuist  be  notifie<l.  any  «»ther 
course,  as  signing  a  certificate  giving  a  fictitious  cau.s«>  of  death.  Ix-ing  not  alone  reprehen.Mble, 
but  very  hazardous.  An  antemortem  statement  :i.s  to  whom  to  blame  for  the  woman's  condition 
is  very  ilesirable,  even  though  the  physician  may  not  use  it.     The  physician  should  obtain  an

accurate  history,  keep  full  records  of  his  findings  and  the  course  of  the  disease,  and  in  holding;  an 
autopsy  on  such  a  case  the  minutest  details  of  the  conditions  found  in  the  pelvis  must  be  observed 
and  noted  carefully  in  duplicate,  especial  s(>arch  being  maile  for  evidence  of  injury. 

The  accoucheur  is  often  called  to  testify  as  expert  in  acciilent  cases,  the  woman  suing  for 
damages  on  the  grountl  that  an  injury  interrupted  her  i)rcgnancy.  The  abortion  must  follow  very 
shortly  on  the  alleged  injury,  or  tiie  death  of  the  ovum  nuist  be  shown  to  have  very  soon  followed 
it,  and  the  ovum  must  be  otherwise  normal,  and  the  woman  i)resent  none  of  the  recognized  causes 
of  abortion,  for  the  medical  witness  to  be  able  to  assert  for  or  against  the  plaintiff.  Indeed,  in 
these  actions  the  witness  can  usually  only  say  that  it  is  or  is  not  probable  that  the  abortion  was 
caused  by  the  accused  injury. 

The  diagnosis  of  a  previous  abortion  may  need  to  b(>  made,  a  subject  which  was  discussed 
under  the  Diagnosis  of  the  Puerperium. 


Fig.  397. — Hematoma  Mole  (Specimen  of  Chicago  Lying-in  Hospital). 

Premature  labor  is  a  labor  in  miniature,  and  hardly  requires  separate  discus- 
sion. Abnormal  presentations  are  more  frequent  than  at  term,  the  breech  present- 
ing thrice  as  often.  Shoulder  presentation  is  also  common,  but  usually  nature 
terminates  the  case  by  either  spontaneous  rectification  or  evolution.  (See  Chapter 
L.)  Special  regard  must  be  paid  to  the  child,  because,  owing  to  its  delicacy,  it 
may  be  injured  during  birth.  Cephalic  presentation  is  the  best  for  premature 
babies,  a  fact  always  to  be  ])orne  in  mind  in  operative  deliveries  before  term;  in- 
deed, the  indication  for  operation  must  be  strict  in  such  cases.  Arrangements  are 
to  be  made  beforehand  to  receive  the  weak  infant  into  a  warm  atmosphere — an 
incubator,  if  possible.     Shock  is  a  vital  factor  with  them. 

Anomalies  in  the  separation  and  expulsion  of  the  placenta  are  perhaps  a  little 
more  common  than  at  term,  and  the  accoucheur  must  see  that  the  uterus  is  thor- 
oughly emptied  and  in  firm  contraction.  Involution  is  slower  than  at  term.  Ergot 
is  to  be  given  for  ten  days  postpartum.

rilAPTKR  XXXIII 
ABRUPTIO  PLACENTAE 

Up  to  1()G4  all  iicmorrlui^cs  occurring  during  prognancy  were  considered  as 
due  to  prenuiture  detaciiincnt  of  the  placenta  from  its  suj)posefl  invariahle  site,  the 
fundus  uteri.  At  this  time  Paul  Portal  proved  that  the  placenta  (-(juld  he  attached 
to  th(>  cervix  at  the  internal  os.  Risl)y,  in  177o.  (iiffcrentiated  hetween  ca-ses  of 
detachment  (^f  the  ])lacenta  situated  alxn-e  the  zone  of  the  dilatation  of  the  uterus 
and  those  l)elo\v  that  zone.  He  said  that  in  the  latter  cla.ss  of  patients,  owing  to  the 
fact  that  the  placenta  must  necessarily  separate  to  allow  the  passage  of  the  child, 
hemorrhage  was  "unavoidable,"  while  in  the  former  the  hemorrhage  is  only  "acci- 
dental" to  the  separation  of  the  ))lacenta.  "Accidental  hemorrhage,"  a  term  still 
in  use,  especially  by  British  authors,  means  the  premature  separation  of  the  nor- 
mally implanted  placenta.  "Unavoidable  hemorrhage"  is  a  tenn  seldom  used, 
but  it  means  placenta  previa,  the  develoi)ment  of  the  placenta  in  the  zone  oi  dilata- 
tion. The  author  suggests  the  term  ''abruptio  placeuUr"  to  take  the  place  of  the 
cumbersome,  generally  used  term,  and  to  go  with  the  short  and  exi)ressive  "pla- 
centa pra'via."  Abruption  of  the  placenta  means  a  forcible  tearing  up  of  the  organ 
from  its  normal  site,  and  in  reality  is  an  abortion  at  or  near  tenn.  Clinically,  it  is 
usually  easy  to  differentiate  between  ]:)lacenta  jinevia  and  abruptio  placentic,  but 
the  author  is  convinced  tiiat  many  of  the  mihler  cases  of  accidental  hemorrhage  are 
due  to  the  detachment  of  the  placenta  situated  low  in  the  uterus,  but  just  al>ove 
the  upper  boundary  of  the  zone  of  dilatation.  The  case  partakes  then  of  the  char- 
acteristics of  both  conditions. 

Abruptio  placenta^,  if  one  includes  the  milder  ca.s('s,  occurs  oftener  than  is 
generally  believed.  Comjilete  sejiaration  (jf  the  iiighly  situated  placenta  is  rare, 
and  probably  occurs  much  less  often  than  once  in  .")00  ca.ses.  In  over  15,000  con- 
finements at  the  Chicago  Lying-in  Hc^sjiital  there  were  only  12  ca.ses  of  complete 
placental  detachment  with  threatening  internal  hemorrhage,  but  there  were,  in 
addition,  31  cases  of  partial  detachment,  the  placenta  showing  a  firm  antepartum 
clot,  and  tiie  clinical  course  of  labor  having  been  distinctly  i)athologic.  Accidental 
hemorrhage  occurs  oftenest  at  the  onset  of  or  during  labor  at  term,  but  it  may  occur 
during  the  last  twelve  weeks  of  pregnancy. 

Causation. — Two  general  causes  are  distinguishable:  (a)  Disea.ses  of  the  pla- 
centa and  of  the  decidua,  and  (h)  traumatism.  In  all  pr<)bal)ility  the  traumas  usu- 
ally accused  act  on  a  diseju^^ed  organ,  and  only  thus  are  efTective,  because  the  healthy 
Uterus  often  tolerates  all  kinds  of  insults — kicks,  blows,  etc. — without  any  reaction. 

Of  the  diseases,  chronic  endometritis  plays  the  most  important  role,  and  it 
may  l)e  gonorrheal,  ^^'int(•r  ])ointed  out  the  fnniuency  of  nephritis  in  abruptio 
placentie;  Feiiling  had  already  shown  the  coincid(>nce  of  placental  infarcts  and 
hemorrhages  in  chronic  nephritis  (the  j)lacenta  all)uminuri(iue  of  the  French).  In 
58  cases  collected  by  Hofmeier  nephritis  was  shown  in  S.i.  CJottschalk  suggests 
that  the  endometrial  changes  and  the  nephritis,  or  the  kidney  of  ]iregnancy,  may 
be  interrelated,  /.  c,  a  toxicosis.  negen<*ration  of  the  decidiia,  myometritis,  syphilis 
of  the  jilacenta,  acute  infectious  diseases  with  de<'idual  hemorrhages,  have  also  l)een 
found.  Basedow's  disea.se  and  arterial  sclerosis  have  been  given  as  causes,  and 
even  a  severe  mental  shock,  through  disturbance  of  the  local  circulation. 

In  the  presence  of  one  of  the  above  conditions  even  a  slight  trauma  may  cause  a

THE  PATHOLOGY  OF  PREGNANCY,  LABOR,  AND  THE  PUERPERIUM 


separation  of  the  placenta,  and  a  hemorrhage  having  been  once  started,  the  blood 
works  its  way  between  the  soft  layers  of  decidua  and  completes  the  abruption.  A 
jar,  turning  suddenly  in  bed,  coitus,  a  IjIow  or  kick  on  the  al)domen,  the  action  of  a 
purge,  severe  coughing,  have  all  been  assigned.  In  Holmes'  collection  of  200  cases 
from  the  literature  accident  was  given  in  67. 

During  labor  several  accidents  may  cause  detachment  of  the  placenta,  as 
sudden  emptying  of  a  large  polyhydramnion,  the  loosening  of  the  placenta  which 
sometimes  follows  the  delivery  of  the  first  twin,  the  retraction  of  the  uterus  above 
the  child,  stopped  in  its  progress  Iw  an  obstruction  in  the  pelvis,  the  opc^ration  of 
version,  when  the  uterine  wall  is  stretched  and  distortetl  by  the  rotation  of  the  child, 
during  delivery  of  the  trunk  in  breech 
presentation,  and,  finally,  traction  ex- 
erted on  the  placenta  by  a  cord  actually 
or  relatively  too  short.

cealed"  Hemorrhage. 


Fig.  399.— Abruptio  Placent.i;;  Combined  Internal  and 
External  Hemorrhage. 


Pathology. — Separation  of  the  placenta  is  always  accompanied  by  marked 
hemorrhage  unless  the  fetus  has  been  dead  long  enough  to  allow  thrombosis  to 
occur  in  the  uterine  sinuses.  Since  the;  full  uterus  cannot  retract  over  its  contents, 
the  sinuses  remain  open  and  the  cavity  of  the  uterus  is  exposed  to  the  full  force  of 
the  arterial  circulation.  The  blood  may  pursue  four  directions:  First  (Fig.  398), 
and  most  rarely,  it  may  })ulge  out  the  uterine  wall  toward  the  abdominal  cavity  and 
})ulge  into  the  cavity  of  the  ovum,  the  edges  of  the  placenta  remaining  attach(Hl  to 
the  uterus;    second,  it  may  dissect  up  the  membranes  all  the  way  round,  severing

almijst  all  the  connections  of  tlic  ovum;  tiiinl,  it  may  l)rcak  into  the  licjuor  amnii, 
and  finally  it  may  seek  a  direct  passage  outward  from  the  edge  of  tlie  placenta  under 
the  membranes  through  the  cervix  into  the  vagina  (Fig.  399;  The  first  three  varie- 
ties are  called  "concealed  hemorrhage,"  and  usually  are  the  most  serious,  hut  in  all 
cases  the  exit  of  the  blood  may  be  blocked  by  the  head  or  membranes  or  a  firm  clot 
plugging  the  cervix.  The  uterus  may  be  immensely  distended  by  the  blood,  the 
author  in  one  case  removing  almo-st  three  pints  of  clots  posti)artum.  Madame 
Boivin  believed  that  the  uterus  at  term  could  not  dilate  sufficiently  to  allow  any 
considerable  hemorrhage,  but  experience  has  jiroved  that  a  fatal  intra-uterine 
hemorrliage  may  occur  without  a  dro])  of  blood  showing  externally.     A  few  reports

are  on  record  wh<'re  the  ])lacenta.  fallen  from  itssitt",  has  come  to  lie  over  the  internal 
OS — prolapsus  placenta'  (Fig.  401).  Most  of  these  cases  were  i)r()bably  i)lacenta 
pr£Evia,  but  a  real  prolap.se  of  the  placenta  occurs,  and  it  makes  a  great  <leal  of  dilTer- 
ence  in  the  treatment.  In  300  cases  collected  by  Holmes  and  Clooilell  193  showed 
external  hemorrhage.  In  all  the  author's  cases  external  hemorrhage  followed  the 
internal,  so  that  th(>  rule  is  that  the  bleeding  in  abrupt io  placentip  is  first  internal 
or  concealed,  then  combined,  external  and  internal.  The  mildest  cas«'  and.  for- 
tiniately,  the  most  common,  is  the  purely  external  hemorrhage  (Fig.  400).  With- 
out doubt  small  hemorrhages  under  the  placenta  occur  frequently  during  the  latter 
weeks  of  pregnancy,  and  organize  without  producing  alarming  symptoms,  hut  are 
discovered  by  the  watchful  accoucheur  in  tlie  evidences  on  the  delivered  placenta;

for  example,  infarcts  aiitl  hard  old,  almost  completely  fibrinous  clots,  adherent  to  or 
incorporated  in  the  membranes  or  decidua.  By  reverting  to  the  history  of  a  slight 
trauma,  a  sudden  pain  in  the  belly,  perhaps  a  slight  bloody  show,  the  connection  is 
made  clear.  The  placenta  in  cases  of  abruption  may  show  the  evidences  of  several 
hemorrhages  or  red  infarcts  of  varying  dates;  it  may  be  torn  or  compressed  by  the 
clots  (Fig.  402),  or  it  may  show  no  signs  save  a  large  retroplacental  hematoma  sim- 
ilar to  tliat  which  occurs  in  the  third  stage  of  labor. 

Symptoms. — With  the  exception  of  the  mild  cases  just  mentioned,  al^ruptio 
placentcB  declares  itself  in  stormy  fashion,  and  medical  aid  is  summoned  early. 
The  severity  of  the  s^niiptoms  depends  on  the  amount  of  hemorrhage,  and  this 
usually  depends  on  the  degree  of  separation.     When  traumatism  is  the  cause,  a

history  of  same  is  given,  but  the  symptoms  may  not  come  on  for  hours  or  even  days 
afterward.  Sudden  severe  pain  in  the  belly,  often  at  the  site  of  the  placenta,  of  a 
tearing  character  at  first,  later  a  dull,  tense  ache,  interrupted  by  colics — these  are 
the  usual  symptoms.  Occasionally  nausea  or  vomiting  occurs.  Now  the  s^-mptoms 
of  acute  anemia  supervene,  and  soon  those  of  shock,  from  sudden  distention  of  the 
uterus,  are  added.  Dizziness,  faintness,  shortness  of  breath,  precordial  anxiety  and 
oppression,  appear  in  order;  the  woman  yawns  or  sighs  frequently,  and  complains 
of  ringing  in  the  ears,  spots  before  the  eyes,  that  she  sees  everything  l)lack,  and  is 
harassed  by  great  thirst.  Later  she  lies  apathetic  on  the  bed  or  may  faint.  This 
loss  of  consciousness  may  last  a  few  moments  to  a  half-hour,  and  is  replaced  by 
restlessness,  jactitation,  or  even  delirium.  Cramps  in  me  legs,  excessive  thirst, 
vomiting,  unconsciousness,  delirium,  convulsive  twitchings,  involuntary  evacua-

tions,  coimi,  death — this  is  the  usual  order  of  the  symptoms  if  the  bleeding  is  not 
stopped.  The  ol)server  will  ncjte  the  inereasing  prostration,  the  growing  pallor  of 
the  skin,  the  white  eheeks  and  gums,  the  sunken  eyes,  the  pearly  conjunctiva',  the 
cold  extremities  and  face,  often  with  an  icy  sweat,  and  in  ca«es  of  shock  an  addi- 
tional tinge  of  cyanosis  about  the  lips.  The  pulse  at  the  very  beginning  may  be 
bounding  and  not  accelerated,  thus  deceiving  the  accoucheur  as  t<j  the  gravity  of 
the  situation.  In  .shock  more  than  in  pure  hemorrhage  the  pulse  at  first  is  likely 
to  be  rapid,  .small,  and  compressible.  Later,  the  bleeding  keeping  u]),  the  hold  of 
the  arterial  walls  on  the  rapidly  diminishing  blood-stream  becomes  insufficient,  and 
the  heart  has  to  pump  faster  to  keep  the  small  amount  of  blood  in  circulation.  In 
some  instances  the  i)ul.se  wi'akens  and  grows  more  rajjid  jxiri  pfi.s.su  with  the  loss  of 
blood.  The  i)ul.se,  therefore,  is  not  always  a  sure  index  as  t(j  what  is  going  on  in 
the  circulatory  system. 

Very  soon  blood  or  serum,  expressed  from  the  intra-uterine  clots,  appears  ex- 
ternally, but  the  amount  of  blood  is  entirely  disproportionate  to  the  gravity  (jf  the 
symptoms.  Examination  of  the  belly  will  siiow  that  the  uterus  is  larger  than  cor- 
responds to  the  given  period  of  jiregnancy,  that  it  ha.s  a  board-like  consistence, 
making  it  impossil^le  to  outline  the  fetus.  An  accessory  tumor,  that  is,  the  sub- 
placental  hematoma,  is  .seUlom  found.  In  all  the  author's  ca.ses,  including  those  of 
external  liemorrhage,  tiie  uterus  was  very  ten.se  and  hard,  but  .some  writers  mention 
a  boggy  and  even  atonic  consistence.  One  would  expect  the  board-like  uterus  in 
the  concealed  cases  and  the  relaxed  uterus  where  the  blood  finds  ready  exit.  Tense- 
ness of  the  belly-wall  because  of  the  distended  uterus  and  the  jiain  is  another  finding. 
The  woman  says  that  the  child  is  not  felt,  but  that  it  was  subject  to  violent  move- 
ments at  the  onset  of  the  accitleiit.  Very  seldom  can  the  fetal  heart  be  heard,  and 
under  such  conditions  a  i)artial  se])aration  of  the  placenta  nmst  be  a.ssumed. 

Labor  usually  comes  on  at  once,  and,  if  the  contractions  of  the  uterus  are  strong 
ami  the  os  dilates  cjuickly,  the  case  terminates  spontaneously — safely  for  the  mother, 
but  almost  invarial)ly  fatally  for  the  infant.  ]\Iore  often  the  woman  dies  unde- 
livered— of  shock  and  hemorrhage — unless  metlical  aid  is  rendered.  Should  the 
detachment  occur  during  delivery,  the  paiiLS  take  on  .strong  expulsive  action  and 
the  child  is  delivered  very  soon,  often  living,  or,  the  accident  having  been  recog- 
nized and  the  conditions  being  favora))le,  the  accoucheur  nuiy  save  both  by  timely 
ojx'rative  interference.  Ra{)id  delivery  of  the  second  twin  and  forcej)s  in  the  second 
stage  are  examples  of  such  operations.  After  the  delivery  the  placenta  and  ma.s.ses 
of  clot  and  fluid  blood  rush  out  of  the  uterus,  and  atony  i)ostj)artum  is  a  frequent 
complication,  due  to  ovcrdistention  and  myometrial  disea.se. 

Diagnosis. — Acute  abdominal  ])ain,  referred  usually  to  one  side  of  the  uterus, 
sudden  increase  of  the  size  of  the  uterus,  with  tension  of  the  abdominal  wall,  .^^oon 
external  hemorrhage,  absence  of  the  fetal  heart-tones,  with  the  general  symptoms 
of  increasing  anemia  and  deepening  shock,  constitute  the  foundation  for  the  direct 
diagnosis.  In  the  difVerential  diagnosis  jilacenta  pra*via.  rupture  of  the  uterus, 
and  extra-uterine  jiregnancy  most  fretiuently  come  uj).  l)Ut  on  rare  occasions  one 
may  have  to  eliminate  other  non-obstetric  accidents,  as  gall-stone  colic,  rupture  of 
an  appendiceal  abscess,  or  gall-bladder  and  intra-abdominal  injuries.

Rupture  of  the  uterus  is  often  complicated  with  detachment  of  the  placenta, 
and,  too,  it  is  possible  that  an  al^ruption  may  tear  the  uterine  wall  or  the  peritoneal 
covering  of  the  uterus.     The  symptoms  of  the  two  conditions,  therefore,  mingle:

1.  Usually  during  pregnanc3^  1.  Usually  during  labor,  unless  from  external 

violence. 

2.  Uterus  enlarged,  tense,  symmetric.  2.  Uterus  small,  at  one  side,  with  neighboring

3.  Uterus  contracting.  3.  No  uterine  pains.

5.  Xo  tear  palpable.  5.  May  feel  the  rent  and  sometimes  the  gut. 

AVith  a  history  of  violent  injury  it  may  be  necessary  to  open  the  abdomen  for 
both  diagnosis  and  treatment. 

Ectopic  gestation  is  indicated  by  the  history,  the  finding  of  the  empty  uterus 
alongside  the  eccentric  and  asymmetric  tumor,  and  the  absence  of  contractions  in 
the  tumor. 

Prognosis. — Goodcll,  in  his  106  cases,  found  54  maternal  and  100  fetal  deaths, 
])ut  he  collected  only  the  critical  ones,  mostly  of  concealed  hemorrhage.  Later 
writers  include  the  mild  and  more  common  abruptions,  and  the  mortality  is  cor- 
respondingly less.  Still,  the  accident  is  one  of  the  gravest  with  which  the  obstet- 
rician has  to  deal,  and  it  is  safe  to  say  that  one-half  of  the  women  and  95  per  cent, 
of  the  babies  in  complete  detachments  with  concealed  hemorrhage  will  die,  while  a 
larger  j^iroj^ortion  will  l)e  saved  with  partial  detachment  and  under  skilful  treatment. 

Treatment. — Divides  itself  into  detachment  occurring  during  labor  and  that 
before  dilatation  of  the  cervix  is  begun. 

If  a  woman  having  apparently  a  normal  labor  suddenly  begins  to  bleed,  one 
thinks  at  once  of  premature  detachment  of  the  placenta,  low  insertion  of  the  pla- 
centa, laceration  of  the  cervix,  and  rupture  of  the  uterus.  An  internal  examination 
will  tell  whether  the  bleeding  comes  from  the  last  fibers  of  the  cervix  giving  way  to 
the  passage  of  the  head  or  from  placenta  prsevia.  Sometimes  the  placenta  may  be 
low  in  the  uterus,  but  out  of  reach  of  the  fingers,  and  here  the  membranes  should  be 
ruptured,  which  is  good  treatment  also  for  detachment  of  the  placenta — at  this 
stage  of  labor — because,  in  the  first  instance,  the  hemorrhage  will  cease  at  once, 
and,  in  the  second,  labor  will  be  so  much  facilitated  that  the  danger  quickly  passes. 
If  the  hemorrhage  continues,  and  especially  if  the  fetal  heart-tones  become  irregular 
or  slow,  a  diagnosis  of  abruption  is  now  made,  and  the  child  should  be  delivered 
without  delay.  If  the  placenta  separates  after  the  first  twin  is  born  or  after  the 
emptying  of  polyhydramnion,  or  during  the  operation  of  version  or  extraction, 
rapid  delivery  is  indicated. 


ABRUPTIO    I'LArKNT.E  443 

Hard  aiul  iJiccisc  rules  cannot  be  laid  d(j\vn  for  the  treatment  of  detachment 
of  the  placenta  during  i)r('y;uancy,  a.s  we  are  able  to  do  for  placenta  pra?via.  Three 
ol)jects  mast  be  accomplislicd:  the  uterus  nmst  be  emptied,  the  hemorrhage  stopped, 
and  the  anemia  relieved.  The  best  treatment  is  that  which  emi)tics  the  uti-rus 
(luickcst  and  with  tiie  least  danK»'r  to  tlu-  mother,  and,  since  the  child  is  almost 
invariably  lost,  Init  little  attenticjn  is  jjaid  to  it. 

The  indication  being  for  immediate  delivery,  the  condition  of  the  cervix  will 
decide  which  method  shall  be  chosen.  If  the  cervix  is  soft  and  partly  ojM'n.the 
dilatation  may  be  c-ompleted  manually  and  forceps  or  version  done,  (Icjx-iuliiiK  on 
the  ('n<:;a}z;eiu(Mit  of  the  head.  When  the  child  is  dead,  craniotomy  takes  the  place 
of  forceps.  If  the  cervix  admits  only  two  fingers  and  is  only  partly  efTaced,  the 
bag  of  waters  is  to  be  punctured,  a  colpeurynter  is  to  be  inserted  in  the  uterus,  filled 
with  eight  ounces  of  sterile  water,  the  vagina  is  to  be  tamponed  as  tightly  as  p<»ssible 
with  dry  stiTiie  cotton,  and  then  a  Idndcr  put  on,  with  as  nuich  counter-compression 
as  the  patient  can  stand.  This  is  obtained  with  a  Spanish  windla.«<s  (Fig.  Aii'.i). 
Ergot  is  administered, — 30  drops  of  the  tluidextract  every  two  hours, — this  Ix'ing 
the  only  condition  in  which  the  author  advises  the  use  of  the  drug  when  the  ovum  is

still  in  the  uterus.  Latterly  1  have  used  i)ituitrin  to  .stimulate  the  pains.  The  wo- 
man is  watchetl  very  doseh',  and  in  the  mean  time  all  preparations  are  completed 
for  eventual  operation,  for  the  treatment  of  jiostpartum  lu-morrhage  and  anemia. 
After  th(!  accoucheur  considers  the  dilatation  sufliciently  advanced,  tlu*  tamjxm  is 
removed,  the  cervix  dilatetl  manually  or  incised,  and  delivery  accomplished. 

Should  the  cervix  be  tightly  clo.sed  and  an  internal  hemorrhage  Im'  going  on, 
the  ca.sc  is  truly  formidable.  Its  gravity  nmst  be  explained  to  the  family  and 
counsel  always  obtained.  The  treatment  is  similar  to  that  just  descrilied.  In  all 
Cii.ses  the  accoucheur  should  be  j)repared  for  all  kinds  of  operative  deliveries  and  for 
postpartum  hemorrhage,  becau.se  atony  of  the  uterus  is  comnmn  .ind,  further,  the 
woman  can  ill  afford  to  lose  blood  at  this  late  jieriod. 

Should  the  membranes  be  puncture*!?  Smellie.  Denman.  Baudelocque, 
Merriman,  Blundell.  Kamsbotham.  and  Kerr  (for  mild  ca.«<es)  recommend  it;  Att- 
hill,  Hicks,  Hamilton,  Burns,  and  Wit  (unless  after  complete  dilatation)  deny  its 
value.  Letting  the  licjuor  anmii  escape  may  give  nxim  in  the  uterus  for  more  blooti 
to  fill,  or  increase  the  shock  by  emptying  the  uterus,  or  interfen*  with  the  mechan- 
ism of  cervical  ililatation.     The.><e  are  theoretic  objections  which  do  not  hold  in 


444  THE    PATHOLOGY   OF   PREGNANCY,    L.\BOR,    AND    THE    PUERPERIUM 

practice,  since  experience  has  shown  that  the  pains  grow  stronger  and  more  efficient; 
that  the  hemorrhage  is  not  increased,  and  that  suljsequent  operative  procedures 
are  not  rendered  difficult  by  letting  the  liquor  amnii  drain  away.  If  the  tampon  is 
to  be  used  w'ithout  the  colpeurynter,  the  membranes  may  not  be  opened. 

If  the  patient  is  in  competent  hands  and  the  surroundings  permit  it,  cesarean 
section,  eventually  the  Porro  operation  if  postpartum  bleeding  is  too  prof  use,  should 
be  performed  when  the  cervix  is  tightly  closed.  Duquet  collected  five  cases,  Kerr 
had  two,  Couvelaire,  one.  Vaginal  cesarean  section,  especiall}'  under  these  cir- 
cumstances, requires  more  skill  and  assistance,  but  may  be  employed  in  selected 
cases.  The  author  has  done  it  thrice  with  success,  and  in  none  of  the  cases  w'as  it 
necessary  to  extirpate  the  uterus  because  of  intractable  hemorrhage. 

If  the  woman  is  in  deep  shock,  the  question  of  any  operative  delivery  must  be 
carefully  debated.  It  may  be  wiser  to  pack  the  vagina  and  put  on  tight  counter- 
compression  until  the  w'oman's  condition  improves,  and  the  time  may  be  utilized 
in  giving  saline  solution  and  stimulants.  When  the  accoucheur  is  convinced  that 
the  bleeding  keeps  up,  operation  is  imperative. 

Rapid  dilatation  by  means  of  a  Bossi  dilator  is  dangerous  and  unsatisfactory.  The  tampon, 
packing  the  vagina  so  full  that  it  almost  fills  the  pelvis,  combined  with  powerful  counterpressure 
by  means  of  an  abdominal  binder,  is  very  highly  recommended  by  the  Dublin  School  for  cases  of 
abruption  with  external  hemorrhage.  Accouchement  force,  the  rapid,  ruthless  dilatation  of  the 
cervix  and  immediate  delivery,  is  to  be  condemned  as  dangerous  and  unsuccessful.  The  women 
often  bleed  to  death  from  the  lacerations  inflicted.  Craniotomy  should  be  used  in  all  cases  when 
the  child  is  dead,  to  reduce  the  amount  of  dilatation  necessary  for  delivery. 

Rupture  of  the  circular  sinus  of  the  placenta,  allo^^dng  maternal  blood  to  escape 
externally,  is  a  rare  accident,  and  one  which  can  hardly  be  diagnosed.  Even  after 
delivery  of  the  placenta  and  the  demonstration  of  the  opening  in  the  sinus  one  may 
not  assert  such  a  diagnosis  because  these  openings  are  found  on  normal  placentas. 
Treatment  is  the  same  as  for  premature  detachment  of  the  placenta.     (See  Budin.)

PLACENTA  PREVIA 

Placenta  iinrvia  is  tlic  (Icvclopiucnt  of  tlic  placcntii  in  part  or  wholly  within 
tiic  zone  of  (lilatatioii  of  tiic  uterus.  That  the  placenta  may  !•<'  found  over  the  os 
was  known  since  Hipjxjcrates'  time,  and  is  mentioned  by  Mauriceau,  Deventer, 
Pup;h,  and  many  others,  hut  they  believed  that  it  had  i)rolapsed  from  its  normal 
fundal  insertion.  Paul  Portal,  in  l(j()4,  stated  j)ositively  that  the  ])lacenta  may  Im- 
imi)lanted  over  the  os,  and  (JitTard,  Roederer,  Levn-t,  and  especially  Smellie,  em-

disunited  from  the  uterine  surface,  that  bleeding  should  occur.  Schaller,  in  1709, 
was  the  first  to  demonstrate  postmortem  the  attachment  of  the  placenta  over  the 
internal  os. 

The  placenta  may  attach  itself  to  any  portion  of  the  uterus,  the  f undal  inser- 
tion being  the  rarest  of  all,  the  posterior  wall  being  the  most  common  site,  next  the 
anterior  wall,  then  the  sides,  and  next  to  the  last  in  frequency  the  lower  uterine

segment — the  isthmus  uteri.  The  lower  edge  of  the  placenta  must  be  at  least  10 
cm.  from  the  internal  os,  and  well  above  the  upper  border  of  the  isthmus  uteri,  to 
be  normal.  When  the  inferior  border  lies  just  at  the  isthmus  uteri,  we  speak  of 
low  insertion  of  the  placenta;  when  this  edge  just  reaches  the  internal  os,  it  is 
called  placenta  prsevia  marginalis  (Fig.  405) ;  when  only  part  of  the  opening  of  the 
cervix  is  covered,  we  speak  of  placenta  prsevia  lateralis  or  partialis  (Fig.  406),  and 


Fig.  407. — Placenta  Pr.evi.^  Totalis  or  Centralis. 


Fig.  408. — Placexta  Pr.evia  Cervicalis. 


when  the  os  is  completely  roofed  over,  placenta  prsevia  centralis  or  totalis  (Fig. 
407).  Since  in  the  last  class  of  cases  the  placenta  lies  almost  entirely  in  the  isthmus 
uteri,  this  might  be  called  placenta  isthmialis.  All  these  terms  are  relative  because 
of  changes  in  the  digital  findings  produced  by  the  dilatation  of  the  uterus — for  ex- 
ample, a  marginalis,  after  the  cervix  is  open,  may  become  a  lateralis,  and  a  placenta 
that  seemed  to  cover  all  the  cervix  with  two  fingers'  dilatation  subsequently  may 
cover  only  half  of  the  opening. 


PLACENTA    PILEVIA 


447 


Causation. — Placenta  pra?via  is  said  to  occur  ten  tinios  as  frctiuontly  in  niulti- 
parrc  as  in  ])riini|)ara',  and  in  general  once  in  lOOO  cases,  liut  no  weight  is  to  l)e 
placed  on  the  statistics,  since  the  figures  given  hy  various  authors  vary  from  1  to 
loOO  to  1  to  300.  Central  placenta  praivia  occurs  in  less  than  one-fifth  of  the  ca.st»s, 
and  iuulti|)aric  are  especially  i)rone  to  the  deeper  varieties,  and  the  tendency  to  the 
low  insertion  increases  with  nmltii)arity  and  age. 

Pre(lis|)osing  causes  are  chronic  endometritis,  nuiltiparity.  <'siM'cially  when 
the  children  come  in  rajjid  succession,  subinv(jlution,  and  twin  j)regnancies. 
These  conilitions  are  likely  to  be  associated.  The  author  in  nearly  all  his  cases 
of  placenta  pran'ia  has  obtained  a  history  of  abortion,  of  slow  recovery  from 
previous  confinement,  of  manual  removal  of  the  placenta  in  j)revious  labor,  of 
recurrent  placenta  ])ra'via  and  other  evidences  of  a  disea.sed  endcjuictrium,  and 
the  findings  on  the  placenta  often  confirm  the  endometritis  as  the  predisposing 
factor — for  examj)le,  white  infarcts,  very  thick  serotina,  adherent  jilacenta. 

The  acting  causes  ar(^— (o)  Primary  low  insertion  of  the  ovum  near  the  int<'rnal 
OS  or  on  its  edge;    (/>)  the  development  of  placenta  m  the  rcflexa  and  its  coming  to

lie  over  the  os  (Ilofmeier  and  Kaltenbach).  Owing.  iH'rhai).^  to  an  endometritis, 
to  lack  of  the  cilia,  or  to  some  unknown  anomaly  of  the  ovum  itself,  the  egg  slijis 
down  the  uterine  cavity  and  does  not  succeed  in  attaching  itself  until  it  reaches  the 
neigiil)orhood  of  the  interntil  os. 

How  the  placenta  grows  over  the  internal  os  has  given  rise  to  much  discussion. 
All  investigators  agree  that  the  ovum  must  be  in.>;erted  low  in  the  uterus.  Since 
the  ovum  burrows  into  the  muco.sa  and  then,  in  its  gro\\ih,  splits  the  decidua  in  all 
directions,  it  is  easy  to  see  how  part  of  the  j^lacenta  could  come  to  cover  the  internal 
OS  (Fig.  410).  The  decidua  vera  and  reflexa  are  carried  across  the  narrow  cervical 
slit  and  come  to  lie  in  apposition  with  the  vera  of  the  opposit«>  side,  where  fusion  may 
or  may  not  occur.  If  the  ovum  splits  the  decidual  membrane  circularly  around  the 
OS,  the  remaining  minute  hole  is  easily  bridged  over,  and  a  horseshoe-shaixKi  or  a 
plnccntn  fenestrnta  n>sults.  The  downward  splitting  (tf  the  decidua  may  not  Im? 
arrested  at  the  internal  os.  In  rare  ca.>^es  the  cervical  mucous  membrane  is  capai>le 
of  forming  decidua.  and  in  this  the  development  of  the  jilactMita  goes  on,  the  villi 
in  their  gro^^'th  reaching  even  to  the  external  os,  as  in  the  author's  ca.«*e  (Fig.  408)

and  in  those  of  von  AVeiss  and  Goodman.  There  are  seven  cases  on  record 
(Ahlfeld,  Wytler,  Devraigne).  The  union  of  placenta  and  cervix  was  very  intimate, 
and  required  actual  digging  out  of  the  placenta  with  the  finger-nail. 

Hofmeier  believed  many  placentae  prseviae  are  due  to  the  development  of  the 
^^lli  in  the  reflexa  (Fig.  411).  Owing  to  peculiar  nutritional  conditions,  the  chorion 
laeve  does  not  atrophy,  but  the  villi  tlevelop  in  the  reflexa  and  this  surface  later  lie- 
comes  applied  to  the  vera  on  the  opposite  wall  of  the  uterus. 

Placenta?  that  have  been  placentae  praevise  exhibit  great  variety  of  form,  two 
having  already  been  mentioned.  Sometimes  there  is  a  tongue  of  tough,  fibrous 
placental  tissue  which  has  overlaid  the  os;  sometimes  the  edge  of  the  os  is  encirck^d 
by  this  placental  tissue,  more  or  less  infarcted.     Occasionally — and  this  in  the  isth- 

mial  variet}'' — the  placenta  hangs  across 
the  lower  uterine  segment  like  a  festoon. 
These  are  the  most  serious. 

Sjrmptoms.— Hemorrhage  is  the  first 
and  most  constant  symptom,  occurring  in 
the  last  three  months  of  pregnane^'- — most 
frequently  in  the  eighth.  Usually  no  cause 
is  assignable,  the  patient  waking  from 
sleep  to  find  herself  in  a  lake  of  blood,  or, 
on  arising  from  the  toilet,  sees  fluid  and 
clotted  blood  in  the  vessel.  A  painless, 
causeless,  uterine  hemorrhage  in  the  third 
trimester  of  pregnancy  is  almost  pathogno- 
nionic  of  placenta  prccvia.  The  first  hemor- 
rhage may  vary  from  a  few  drops,  hardly 
a  stain  on  the  linen,  to  a  profuse  "flood- 
ing," which  may  be  fatal  at  once,  but  usu- 
ally a  few  ounces  are  lost  as  the  initial 
symptom.  Each  succeeding  hemorrhage 
is  greater,  and  unless  treated,  a  high  grade 
of  anemia  is  developed.  The  accoucheur 
must  not  be  misled  by  apparent  recovery: 
this  is  never  complete  during  pregnancy— 
the  blood  is  only  "patched  up";  the  sys- 
tem is  not  in  a  condition  to  withstand  a 
new  drain,  one  that  is  inevitable  at  labor. 
Some  of  the  worst  cases  of  spanemia  are 
produced  by  a  condition  called  still icidiiwi 
sanguinis,  which  is  a  continuous  but  very  slight  dribbling  of  blood,  hardly  com- 
manding the  notice  of  the  accoucheur,  but  slowly  undermining  the  woman's  con- 
stitution.    Labor  usually  comes  on  after  the  second  or  third  hemorrhage. 

In  central  insertion  of  the  placenta  the  bleeding  usually  occurs  earlier  than  in 
the  other  varieties,  but  exceptions  are  noted,  the  cervix  remaining  closed  and  there 
being  no  hemorrhage  until  full-term  labor  begins.  Such  cases  have  weak  pains 
and  are,  therefore,  unfavorable.  In  partial  placenta  praevia  the  pains  of  pregnancy 
are  usually  present;  hemorrhage  is,  therefore,  more  constant;  the  cervix  softens 
and  dilates,  and  treatment  during  labor  is  facilitated.  Marginal  placenta  praevia 
may  not  cause  hemorrhage  until  the  very  beginning  of  labor,  or  even  towartl  the 
end  of  the  first  stage,  and  then  it  is  slight.  One  may  suspect  the  type  of  placenta 
praevia  from  the  above  symptoms,  but  exceptions  to  the  rules  are  verj^  common,  the 
author  having  met  a  severe  and  almost  fatal  hemorrhage  from  a  marginal  insertion 
and  another  case  of  mild  bleeding  in  a  complete  placenta  previa.  Ahlfeld  and  Kdgar 
lost  patients  from  one  profuse  hemorrhage,  and  only  an  edge  of  the  placenta  pre-

sentcd.  Perhaps  tlie  manner  of  development  of  tlie  placenta  pra>via  may  exi)lain 
these  variations  in  the  amount  of  hemorrhafic 

The  orif^in  of  tlie  liciiiorriuitic  is  fourfohl:  Fnjiij  tlie  sinuses  of  the  placental 
site;  from  the  intervillous  spaces  of  the  jjlacenta;  fr<im  the  circular  sinus  of  the 
placenta;  rarely,  and  then  only  as  the  result  of  interference,  from  the  villi — that  is, 
the  fetal  blood-vessels.  Owing  to  the  development  of  the  isthmus  uteri  antl  the 
lower  uterine  sep:inent,  antl  the  constant  upward  retraction  of  the  fibers  of  the  lower 
l)ortion  of  the  uterus,  the  area  occupied  by  the  i)lacenta  is  cnlarncil,  but  the  i)la- 
cental  j^rowth  is  not  in  i)roportion.  During  the  ])ainless  ut<'rine  contractions  of 
prefj;nancy  the  lower  edge  of  the  placenta,  tiierefore,  is  likely  to  ix-  <lisunite<l  from 
the  wall  of  the  uterus,  opening  the  sinuses  and  allowing  maternal  bloo<l  to  escajK*. 
It  is  easy  to  see  why  such  heniorrliage  is  called  unavoidal)le. 

Other  symptoms  of  i^laccnta  pru'via  are  both  inconstant  and  ccpiivocal,  as 
jiain,  i)ressure,  and  throbbing  in  tiie  lower  abdomen,  frc(|U('nt  urination.  Icukor- 
rhea,  and  "carrj'ing  the  child  dilferently." 

Placenta  previa  affects  the  course  of  pregnancy,  lal)or,  and  the  puerperium. 
Abortion  is  nc^t  seldom  the  result  of  it,  th<jugh  liofmeier,  in  sixteen  years'  exjM'ri- 
ence,  could  not  find  one.  In  several  ai)ortions  the  author  found  indul»itai)le 
evidences  of  low  implantation  of  the  ovum.  Many  ea.ses  of  placenta  pnevia  give  a 
history  of  threatened  abortion  in  the  early  months.  Premature  rupture  of  the  bag 
of  waters  is  another  sign  of  low  insertion,  usually  the  marginal,  and  is  due  to  the 
adherence  of  the  mem])ranes  around  the  os,  from  catarrhal  endometritis  or  abn<»rmal 
l^lacentation.  Premature  lal)or  is,  therefore,  connnon.  Doranth  fcjund  full-term 
labor  in  onlj'  32  per  cent.  Some  authors  mention  that  ]>regnancy  may  go  Ix'yond 
term  in  placenta  previa  centralis,  but  I  have  had  contrary  experience. 

During  labor  the  low  implantation  of  the  bulky  placenta  cau.ses  malpositions 
and  mali)resentations,  for  examj^le,  breech  and  shoulder;  delayed  engagem<'nt  of 
the  head;  al)normalities  of  rotation;  prolapsus  funis;  weak  ])ains — all  these  plus 
the  inevitable  hemorrhage  and  the  injuries  so  commonly  inflicted  by  operative  tk'- 
livery.  Air-embolism  because  the  uterine  sinuses  are  so  near  the  external  air,  and 
rupture  of  the  uterus,  because  the  musculature  is  weakened  by  the  ingrowth  of  the 
l)lacenta,  are  conunoner  than  usual. 

Postpartum  hemorrhage  is  very  frequent,  because  the  uterine  wall  is  thin  and 
weak  in  muscle,  which  contracts  tardily,  and  closes  imperfectly  the  large  venous 
simises,  also  often  being  unable  to  sejxirate  the  placenta.  Further,  the  placenta  is 
likely  to  be  adherent  because  of  endometritis,  infarction,  ingrowth  of  villi  (plac«-nta 
accreta.  Fig.  704),  or  from  infection  during  pregnancy,  the  placenta  lu-ing  so  near 
the  septic  vagina.  Did  not  the  uterine  arteries  enter  the  uterus  higher  uj)  and, 
therefore,  in  the  zone  of  contraction,  raanj'  women  would  bleed  to  death,  because 
the  clotting  in  tlie  vessels  is  not  sufficient  to  procure  hemost:Lsis.  No  (.U)ubt  many 
cases  of  ])(jsti)artum  hemorrhage  are  due  to  low  imi)laMtation. 

In  the  puerjierium  placenta  pnevia  also  makes  trouble:  («/)  Bits  of  i)lacenta 
may  remain  adherent  and  become  infected;  (6)  from  the  clo.se  proximity  of  the 
l)lacental  site  to  the  septic  vagina,  infection — antl  that  of  the  mo.st  tlangerous  kind, 
metrophlebitis — is  invited;  (c)  subinvolution,  and  (</)  finally  the  wt)man  has  the 
profound  anemia  to  ct)ntentl  with. 

These  tlangers  l)e.set  the  chiltl:  prematurity  antl  atelectasis  pulmonuin;  a 
much  infarct ed  or  ill-tlevelopetl  placenta  causes  the  infant  to  be  puny ;  prolapse  t)f  the 
ct)rd;  ctnni^ression  of  the  insertion  of  same,  antl  dislocation  of  the  placenta  tluring 
tlelivery,  may  cause  asjihyxia;  injury  of  the  platrnta  causes  fetal  hemorrhage;  and 
the  infant  may  suffer  from  the  forceps  or  version,  but  esiwcially  from  the  use  of  its 
body  as  a  tampon  to  stop  hemorrhage — the  Braxttm-Hicks  metlu»d. 

Diagnosis. — A  painless,  causeless,  uterine  hemt)rrhage  n  the  last  three  months 
of  pregnancy  usually  enables  a  tlirect  tliagnosis  of  placenta  pnevia  to  be  matle,  but

450      THE  PATHOLOGY  OF  PREGNANCY,  LABOR,  AND  THE  PUERPERIUM 

the  conclusion  must  be  certified  by  vaginal  examination  and  the  finding  of  placental 
tissue  over  the  internal  os. 

Before  making  the  internal  examination  everything  must  be  prepared  as  for 
operation,  and  great  gentleness  is  to  be  practised  to  avoid  separating  and  tearing 
the  placenta,  the  dangers  being  maternal  and  fetal  bleeding.  It  has  happened  that 
the  mere  insertion  of  the  finger  into  the  cervix  has  provoked  such  alarming  hemor- 
rhage that  treatment  had  to  be  instituted  there  and  then. 

The  peculiar  spongy,  fil)rous  feel  of  the  placental  tissue  ma}'  be  simulated  by  a 
firm  coagulum,  by  thick  vcrnix  caseosa  in  matted  hair,  by  a  monstrosity'  with  ex- 
posed viscera, — for  example,  anenccphalus, — by  hemorrhage  into  the  fetal  mem- 
branes (which  ma}'  indicate  a  placenta  located  near  by),  and  by  thickened  mem- 
branes. Bogginess  in  the  fornices,  the  sensation  of  a  flat  sponge  between  the  head 
and  the  fingers,  pulsating  arteries,  excessive  vascularity,  and  a  low  and  pronounced 
uterine  souffle  are  all  equivocal  signs  of  placenta  prsevia. 

In  the  differential  diagnosis  bleeding  from  varicose  veins,  hemorrhoids,  etc., 
are  easily  excluded,  but  ruptura  uteri,  ectopic  gestation,  and  abruptio  placentae 
need  more  care.  (See  p.  441  for  a  table  which  gives  the  differential  points  con- 
cerning the  last  mentioned.)  It  must  be  remembered  that  a  placenta  situated  low 
in  the  uterus  without  being  actually  a  prsevia  may  become  partly  detached  at  its 
lower  pole,  and  the  point  of  bleeding  being  near  the  os,  the  blood  escapes  readily, 
not  increasing  intra-uterine  tension  and  not  separating  the  placenta  entirely.  In 
such  instances  the  signs  of  abruptio  may  be  wanting.  Then,  too,  in  the  severest 
cases  of  abruptio  placentae  the  organ  may  prolapse  and  come  to  lie  over  the  os. 

Rupture  of  the  uterus  is  easily  shut  out,  but  one  must  remember  the  tendency 
of  the  uterus  to  rupture  w^hen  the  placenta  is  low. 

Bleeding  from  a  vessel  passing  over  the  os  from  a  velamentous  insertion  of  the 
cord  must  also  be  thought  of,  and  also  laceration  of  the  circular  sinus. 

Another  point  to  be  determined  l^y  the  internal  examination  is  whether  the 
previal  portion  of  the  placenta  is  central,  lateral,  or  only  marginal — which  is  not 
always  easy.  Sweeping  the  finger  delicately  around  the  internal  os,  the  accoucheur 
notes  where  the  thin  membranes  become  thicker,  then  passing  into  the  thick  pla- 
cental margin.  If  the  student  will  lay  a  placenta  over  a  ring  made  by  his  fingers, 
he  can  practise  the  diagnosis  of  placenta  praevia  as  on  the  living. 

Prognosis.^ — Placenta  praevia  is  a  formidable  complication,  and  annually  sacri- 
fices more  mothers  and  children  than  appear  in  statistics.  These  figures,  collected 
from  many  sources,  will  give  an  idea  of  the  mortality  of  mothers  and  children.

This  table  shows  that,  of  21r>^  women  with  placenta  praevia,  16G  died,  a  per- 
centage of  7.7,  which  is  very  much  better  than  fifty  years  ago,  by  grace  of  asepsis 
and  better  obstetric  practice.  The  Berlin  Frauenklinik  showed  3.8  per  cent,  of 
deaths  in  467  cases,  and  Schauta's  Vienna  clinic,  5.85  per  cent,  in  342  cases.  Kronig 
collected  6569  cases  which  showed  mortalities  of  9.3  per  cent,  and  58.7  per  cent, 
respectively  for  mothers  and  children.  Fiith  collected  726  cases  from  private 
practice  near  Koblenz,  and  found  143  deaths,  19.7  per  cent.,  with  an  infant  mor-

tality  of  48  per  cent.  McPherson,  in  250  ca-scs  in  tin-  New  York  LyiiiK-in  Hcjspital, 
found  18  jjcr  cent,  and  57  per  cent.,  hut  in  this  arc  in(  ludcd  the  niorihund  cases. 
McDonald  collected  reports  of  8G25  cases,  and  found  7.22  \ht  cent,  and  55.5  p«'r 
cent,  mortalities  for  mothers  and  children  respectively. 

All  these  figures  require  careful  study  before  heing  applied  to  any  jiurix^H', 
especially  for  deciding  on  methods  of  treatment,  hecau.se  the  condition  of  the  i)a- 
tient.  whether  she  was  infecte(l  before  admi.ssic^n  to  treatment,  tin*  degree  of  the 
pra'via,  total  or  partial,  the  period  of  gestation,  the  amount  of  blood  lo.st  previously, 
the  manner  of  treatment,  etc.,  must  all  be  properly  evaiuateti—  which  is  imixj.ssible. 
One  man's  opinion,  if  he  is  (|ualified  by  general  mental  ability  and  clinical  experience 
to  render  an  opinion,  is,  tiiereforc,  usually  more  useful  in  de<'iding  on  lines  of  treat- 
ment than  the  largest  statistics.  The  iiighest  mortality  occurs  in  central  placenta 
prievia;  the  lowest  in  the  marginal  variety,  which  is  true  for  both  mother  and  infant. 

Most  otthe  deaths  in  placenta  pra*via  come  from  hemorrhage,  sepsis,  rupture 
of  the  uterus,  and  air  embolism,  named  in  the  order  of  fre(|uency.  The  W(»man 
bleeds  to  death  in  lal)or  usually  l)ecau.se  her  st(jre  of  blood  has  lu-en  wasted  during 
pregnancy,  or  from  an  injury  inflicted  by  delivery.  Sepsis  is  invited  by  the  pro.xim- 
ity  of  the  su-sceptible  j)lacental  site  to  the  field  of  operation,  and  the  fact  that  ha.'^ty 
and  many  manipulations  are  necessary  in  the  treatment.  Rupture  of  the  uterus 
is  usually  the  result  of  violence  exerted  l)y  the  accoucheur,  but  may  (x-cur  from 
tumultuous  uterine  action.  Air-embolism  is  rare,  but  does  occur,  ex])eriments  on 
animals  to  the  contrary  notwithstanding,  l^he  children  die  from  asphyxia  through 
dislocation  or  compression  of  tiie  i)lacenta,  tearing  of  the  placenta  and  fetal  hemor- 
rhage, from  being  usetl  as  a  plug  in  the  Bra.xton-Hicks  treatment,  further,  from 
prematurity.     Later  methods  of  treatment  have  imjmn-ed  the  child's  chances. 

The  prognosis  as  to  health  is  also  l)ad.  Puerperal  infection  is  of  very  fre(iuent 
occurrence,  resulting  in  life-long  invalidism;  the  anemia  may  cause  permanent 
changes  in  the  blood-forming  organs  and  in  the  nervous  .sy.stem,  and  the  woman 
may  l)e  damaged  by  the  ojierations  j)erformed  for  delivery. 

Treatment. — Fortunately,  we  po.ssess  rational  ami  certain  methods  of  treat- 
ment for  this  formidable  accident,  which  cannot  be  saitl  of  most  other  obstetric 
complications.  In  deciding  on  the  course  of  procedure  in  the  individual  cai^e  many 
factors  must  be  considered:  the  surrountlings  of  the  jiatient;  the  condition  of  the 
mother  and  that  of  the  child;  the  necessity  for  jireserving  it  (Catholic  family);  the 
skill  of  the  accoucheur;  the  degree  of  tiie  i)ra>via— whetlier  partial  or  total;  whether 
the  patient  is  in  labor  or  not;  and  the  amount  of  dilatation  of  the  cervix.  From 
his  own  experience,  and  from  thoughtful  consideration  of  the  publishetl  experience 
of  others,  the  author  would  lay  down  these  axioms: 

1.  A  woman  with  ])lacenta  i)ra'via  should  not  die,  except  in  the  very  rare  in- 
stances of  air-embolism,  hemorrhagic  diathesis,  or  spontaneous  rupture  of  the  uterus. 

2.  Every  woman  with  placenta  jirania  should  l)e  sent  to  a  well-<'(]uipiKHl  ma- 
ternity hospital  unless  she  is  able  and  willing  to  i)rovide  the  several  physicians  and 
nurses  necessary  in  her  own  home.  It  is  othersNise  imixjssible  to  give  the  patient 
all  the  benefits  of  our  art. 

3.  With  two  exceptions  every  pregnancy  complicated  with  plac<nta  previa 
shoukl  be  terminated  as  soon  as  the  diagnosis  is  made.  When  the  bkn'tling  is  in- 
deed slight,  and  when  tiie  child  is  very  near  the  lH)rder  of  viability,  one  may  tem- 
porize a  few  weeks,  proridinii  the  patient  will  remain  in  betl  in  a  qikhI  maternity  hos- 
pital. Should  the  woman  refuse  to  go  to  tlu*  hospital,  and  also  to  allow  the  ac- 
coucheur to  induce  lal)or  at  her  home,  the  attendant  had  l>etter  droji  the  case  and 
let  the  patient  employ  a  physician  in  whom  the  gambling  instinct  is  l>etter  develojKHl. 
A  "flooding"  may  occur  during  the  night,  and  the  woman  lose  a  fatal  amount  of 
blood  before  aid  can  reach  her.  Dr.  \\'.  \\'.  .laggard  said,  "there  is  no  e.xi>ectant 
plan  of  treatment  for  placenta  pnevia." 


452      THE  PATHOLOGY  OF  PREGNANCY,  LABOR,  AND  THE  PUERPERIUM 

4.  One  must  distinguisli  sharpl}^  between  maternity  and  jirivate  practice, 
measures  which  are  safe  in  tlie  former  being  impossible  in  the  latter.  In  the  ma- 
ternity hospital  one  may  make  a  consistent  effort  to  save  th(»  life  of  the  child,  but 
at  the  home  one  must  use  that  method  which  A\ill  put  an  immediate  stop  to  the 
hemorrhage,  with,  if  necessary,  less  regard  to  the  child.  Also  the  accoucheur  will 
select  the  procedure  which  he  is  best  able  to  carry  out,  and  must  know  all  methods 
of  delivery,  as  well  as  l)e  able  to  suture  the  cervix  and  perform  vaginal  and  abdom- 
inal hysterectoni}',  etc. 

5.  When  labor  has  begun  in  a  case  of  placenta  praevia,  the  accoucheur  must 
remain  by  the  patient  until  she  is  delivered  and  out  of  danger. 

6.  At  all  times  in  the  treatment  of  these  cases  the  accoucheur  should  heed  this 
warning,  save  blood!  One  can  never  foretell  how  much  of  the  vital  fluid  the  woman 
will  lose  in  the  successive  stages  of  treatment,  nor  does  one  know  what  is  the  par- 
ticular woman's  ability  to  's\dthstand  bleeding.  A  loss  of  a  pint  will  kill  one  woman, 
while  another  will  recover  from  the  loss  of  three  quarts.  Be  not  extravagant  with 
her  supply  during  the  first  and  second  stages  of  labor,  because  the  normal  flow  in 
the  third  stage  may  be  a  fatal  drain.  Therefore  if,  on  arrival  at  the  bedside,  the 
accoucheur  finds  the  woman  already  anemic,  it  is  unwise  to  use  uncertain  methods, 
but,  regardless  of  all  else,  the  hemorrhage  must  be  arrested  at  once  and  every 
possible  drop  of  blood  spared. 

During  pregnancy,  before  labor-pains  have  begun,  if  one  has  decided  to  assume 
the  risk  and  to  temporize,  the  woman  should  be  put  to  bed  at  the  first  indication 
of  hemorrhage,  and  she  should  be  in  a  perfectly  appointed  maternity  hospital.  If 
the  hemorrhage  is  free,  a  firm  vaginal  tampon  is  to  be  applied.  In  all  cases  of 
hemorrhage  during  prt'gnancy  a  firm  tampon  is  indicated,  in  order  to  limit  the  loss 
of  blood  to  a  minimum.  If  the  woman  is  to  be  transported  to  a  hospital,  a  provi- 
sional tampon  is  to  be  applied,  as  the  unavoidable  jolting  on  the  way  will  increase 
or  incite  the  bleeding.  The  application  of  a  tampon  to  control  hemorrhage  is  by 
no  means  a  simple  matter.  Unless  the  head  is  engaged  in  the  pelvis,  it  is  impossil)le 
to  apply  the  tampon  so  firmly  that  all  lileeding  will  l)e  stopped,  and  since  the  head 
rarely  has  sunk  so  low,  one  must  be  content  with  checking  the  flow.  Dry  sterile 
cotton  is  best  for  the  purpose,  and  the  rules  of  asepsis  must  be  especially  strict. 
Counterpressure  is  to  be  applied  "with  a  firm  abdominal  binder,  as  in  Fig.  403. 
Even  an  aseptic  tampon  aseptically  applied  becomes  a  source  of  danger  verj'  soon, 
and  for  this  reason  it  should  l^e  removed  in  twelve  hours  and  not  renewed  unless 
absolutely  necessary.  On  the  appearance  of  another  hemorrhage  action  is  de- 
manded— ^there  is  no  wisdom  in  waiting  longer.  It  is  a  wanton  exposure  of  the 
mother  to  immediate  and  future  danger  for  the  sake  of  an  infant  which  will  prob- 
ably succumb  during  delivery  or  shortly  after. 

If  the  patient  is  near  the  ninth  month,  the  child  is  viable  and  well  developed, 
and  on  its  account  there  is  no  reason  for  waiting. 

During  labor  we  have  four  objects  to  accomplish:  First  and  most  urgent,  to 
stop  the  heinorrhage;  second,  to  empty  the  uterus;  third,  to  insure  hemostasis; 
fourth,  to  combat  the  anemia. 

We  must  stop  the  hemorrhage,  then,  first  of  all,  and  it  matters  a  great  deal 
whether  the  patient  has  already  lost  much  or  little  blood  wh(ni  it  comes  to  the  selec- 
tion of  the  method  of  stanching  the  flow. 

In  cases  of  marginal  plac(nita  praevia  the  hemorrhage  usually  l)cgins  toward  the 
end  of  the  second  stage  of  lal)or  and  is  very  slight.  The  proper  treatnunit  is  to 
puncture  the  bag  of  waters.  This  method  is  named  after  Puzos,  who  mentioned  it 
(1759),  but  Puzos  knew  nothing  of  the  nature  of  placenta  previa,  and,  further, 
Mauriceau  ruptured  the  membranes  to  stop  hemorrhage  in  1688.  Both  considered 
detachment  of  the  placenta  the  cause  of  all  the  hemoi-rhag(\s  during  ])regnan('y.

of  waters  will  fail  to  arrest  the  flow.  Such  cases  are  treated  like  central  and  lateral 
implantation. 

The  usual  condition  met  is  a  more  or  less  severe  hemorrhage,  with  the  os  ad- 
mitting two  or  more  fingers.  Pains  may  or  may  not  be  present,  Ijut  some  uterine 
action  must  have  taken  place  or  the  hemorrhage  and  dilatation  could  not  have 
oe^'urred. 

There  are  now  two  methods  of  treatment — Braxton-Hicks'  version  and  met- 
reurysis. Which  oneshouUl  beselected  dependson  several  conditions.  If  the  woman 
has  lost  much  blood;  if  the  babe  is  dead  or  dying,  or  if  it  is  very  ])remature,  so 
that  its  chances  are  very  slim;  if  one  has  had  littleexperiencewith  placenta  praevia — 
Braxton-Hicks'  version  is  preferable.     Bring  down  one  foot,  make  slight  traction  on

Breech  acts  as  tampon  and  squeezes  placenta  against  bleeding  vessels.     It  is  e.ssential  for  success  to  be  certain  that

it,  so  that  the  infant's  thigh  compresses  the  placenta  against  the  cervix,  thus  stop- 
ping the  hemorrhage.  Then  leave  the  case  to  nature.  Do  not  extract  the  child;  do 
not  put  traction  on  the  leg  unless  bleeding  recurs.  If  oozing  commences,  pull 
lightly  on  the  leg.  The  object  of  this  method  is  to  use  the  child's  bod}'  as  a  cer- 
vical tampon  to  stop  hemorrhage,  and  to  stimulate  pains  until  the  cervix  is  ready 
for  safe  delivery.  Neglect  of  the  above  ad\'ice  and  rapid  extraction  have  cost  many 
mothers  their  lives,  and  the  object  sought,  the  saving  of  the  child,  has  usuall}'  been 
frustrated  by  the  attempt  itself. 

In  porforming  Braxton-Hicks'  version  these  points  arc  to  be  noted.  Puncture  the  mem- 
branes at  the  side  of  the  cervix  a.s  far  from  the  edge  of  the  placenta  as  possible  (Fig.  412).  Then, 
disregarding  the  bleeding,  which  now  commences  and  is  sometimes  furious,  pass  the  hand  into  the 
vagina, the  two  fingers  through  the  rent  in  the  membranes  alongside  the  head.  The  head  is  gently 
])ushe<l  to  one  side,  while  the  outside  hand  presses  first  the  breech,  then  the  foot,  down  in  the  direc- 
tion of  the  inside  fingers.  The  fingers  seek  the  foot,  and  as  soon  as  this  is  grasped,  it  is  led  down 
into  the  vagina.  It  is  then  very  gently  drawn  out,  the  other  hand  outside  pressing  the  head  up- 
ward toward  the  fundus.     The  secret  in  the  jierformance  of  Braxton  Hicks'  version  is  complete

be  removed,  because  anemic  patients  do  not  do  well  with  anesthetics.

It  is  applicable  at  all  stages  of  cervical  dilatation,  before  the  os  is  sufficiently  open 
to  permit  delivery.  It  may  be  used  to  induce  labor,  or  it  may  be  used  when  version 
has  been  tried  and  has  failed.  One  may  dilate  the  cervix  sufficiently  to  proceed 
with  immediate  delivery,  or  one  may  dilate  sufficiently  for  the  p(n-formance  of 
version,  after  which  the  case  may  be  treated  according  to  conditions  as  they 
arise.  The  colpeurynter  (or  metreurjTiter)  marks  nearly  as  great  an  advance 
in  the  treatment  of  placenta  prsevia  as  did  the  introduction  of  Braxton-Hicks' 
version.  ]\Ietreurysis  is  used  in  cases  where  the  condition  of  the  mother  and  child 
is  gootl.  When  the  mother  has  lost  little  blood  antl  the  child  is  viable,  we  may 
take  a  reasonable  chance  on  a  little  greater  hemorrhage  for  the  sake  of  the  infant. 


Fig.  416. — Filling  Colpeurynter.     (Some  operators  prefer  a  piston  .sjTinge.) 

Sovoral  bases  are  on  the  market.  The  oi-iginal,  Carl  Braiin  colpeurynter,  is  as  <j;ood  as  any 
of  the  later  modification.s,  and  I  use  it  considerably  (Fig.  795,  p.  9ilj.  Voorhees,  of  New  York, 
made  a  modification  of  the  Champeticr  de  Ribes'  inelastic  conic  balloon,  which  is  very  service- 
able, and  sizes  may  be  gotten  large  enough  to  secure  complete  dilatation.  I  use  it  in  cases  in  which 
the  head  is  low  in  the  pelvis,  as  its  flat  top  does  not  displace  the  head  much. 

All  preparations  are  made  beforehand.  The  bag  and  the  bulb  syringe  for  filling  are  sterilized 
by  boiling  twenty  minutes  in  plain  water.  The  colpfnuynter  is  emptied  of  air  first.  This  is 
accomplished  by  filling  it  with  0..5  per  cent,  lysol  solution,  then  inverting  it  so  that  all  this  tiuid 
runs  out.  A  clamp  is  now  affixed  four  inches  from  the  end  of  the  tube.  The  air  is  all  pumped 
out  of  the  bulb  syringe  and  the  nozle  fitted  into  the  end  of  the  tube  of  1h(>  colfx'urynter.  For 
greater  security  this  tube  may  be  lied  on  with  tape.  The  bag  is  now  folded  len<!;thwise  into  as 
narrow  a  compass  as  possible,  and  then  grasped  by  the  long  uterine  packing  forceps.  The 
whole  apparatus  lies  in  a  basin  of  0.5  per  cent,  lysol  solution,  from  which  it  is  to  be  filled. 

The  membranes  are  now  punctured  as  for  the  jierformance  of  vc^rsion,  and,  op(>rating  quickly, 
guided  by  llie  two  fingers  in  the  cervix,  the  bag  (Fig.  415)  is  placed  inside  the  uterus  on  top  of  the

This  accomplished,  the  accoucheur  .seats  himself  at  the  bedside  and  maintains  slight  traction  on

chikl  (Fig.  41S).  It  is  a  very  serious  loss,  because  one  cannot  control  the  hemorrhage  so  well 
after  dilatation  of  the  cervix  as  before,  unless  it  is  possible  to  deliver  at  once.  Sometimes  the  head 
follows  down  and  takes  the  place  of  the  colpeurynter,  tamponing  the  cervi.x  securety.  These  are 
fortunate  cases,  and  one  has  nothing  to  do  but  watcli  and  let  nature  take  the  lead.  It  is  advisable, 
as  soon  as  the  head  has  passed  the  cer\-ix,  to  deliver,  because  the  child's  life  is  in  a  rather  precarious 
position,  and,  second,  the  placenta  may  separate  and  blood  may  accumulate  in  the  uterine  ca\'ity. 

The  accoucheur  determines  that  the  colpeurynter  is  passing  the  cervix,  first,  by  noting  the 
steady  advancement  of  tlie  tube;  by  occasional  direct  internal  examination  one  feels  the  cervix 
shpping  over  the  greatest  circumference  of  the  bag;  third,  the  patient  begins  to  bear  down,  and 
the  pain  has  a  sharp,  cutting  character;  fourth,  after  the  bag  has  passed  through,  the  pains  cease 
or  are  milder;  fifth,  the  bag  is  expelled — but  the  two  latter  signs  show  delinquency  on  the  part  of 
the  accoucheur.  By  the  time  the  bag  comes  to  pass  through  the  cer^^x,  the  attendant  must  be 
ready  to  deliver  or  to  do  a  version,  as  indicated.  The  time  consumed  in  getting  ready,  after  the 
bag  has  slipped  through  the  os,  may  mean  a  fatal  loss  of  blood. 

If  the  head  does  not  follow  the  metreurynter  into  the  pelvis,  the  operator  withdraws  the  bag 
quickly  from  the  vagina,  emptying  it,  if  necessary,  as  ([uickly  inserts  his  whole  hand,  and  grasps 
the  cervix  and  placenta  mitil  he  can  determine  on  the  course  of  procedure.     If  the  head  is  still

high,  he  tries  to  force  it  down  into  the  pelvis.  This  will  stop  the  hemorrhage  and  allow  the  forceps 
to  be  applied.  If  the  head  does  not  go  into  the  pelvis,  podalic  version  is  to  be  performed.  If 
the  cervix  is  not  sufficiently  dilated  by  the  first  attempt  with  the  colpemynter,  one  may  reinsert 
it  and  fill  it  with  a  still  larger  amount  of  water, — 20  to  24  ounces, — which  will  dilate  the  os  to  the 
size  of  the  fetal  head. 

The  heart-tones  of  the  child  must  be  carefully  noted  after  the  version  is  done 
and  during  the  time  the  colpeurynter  is  in  place.  If  the  cord  is  in  the  area  of  the 
placenta  compressed  by  the  breech  or  colpeurynter,  some  asphyxia  of  the  infant  is 
unavoidable.  This  may  not  be  fatal,  but  is  very  unwelcome,  the  more  so  because 
we  are  practically  powerless  to  extract  the  child  until  the  cervix  is  dilated.  The 
most  we  can  do  is  to  try,  if  safe,  to  hasten  the  dilatation  of  the  cervix  somewhat. 
This  is  done  by  exerting  a  little  more  traction  on  the  ])reech  or  l^ag,  say  2}-4,  pounds — 
\\ith,  of  course,  the  precautions  already  emphasized.  If  an  urgent  indication  on 
the  part  of  the  child  for  delivery  should  arise  before  the  cervix  is  sufficiently  dilated, 
it  will  have  to  be  disregarded.  The  danger  of  haste  is  too  great  for  the  motlier. 
An  indication  for  delivery  will  not  arise  on  the  part  of  the  mother,  jjecause  we  can

water,  and  sees  that  there  is  a  supply  of  sterile  solutions,  s|)onges,  towels,  etc.  As 
a  rule,  the  cervix  may  1m'  sufficiently  jirepared  to  ]>ermit  delivery,  but  let  me  again 
sound  the  warning — Beware  of  tuo  ha.sty  extraction  throiujli  a  poorhj  dilated  cervix! 
The  laceration  of  the  highly  vascularized  cervix  is  one  of  the  mo.st  formidable  acci- 
dents the  accouclieur  could  meet.  The  uteroplacental  sinuses  are  .so  superficial  that 
a  tear  }  s  hich  deej)  may  lay  one  open.  The  contraction  and  retraction  of  the  lower 
uterine  segment  are  poor  at  best,  and  poorest  in  placenta  i)r;evia.  and  this  means  of 
hemostasis  is  not  .strong,  so  that  the  cases  of  fatal  hemorrhage  from  even  tiny  tears 
of  the  placental  site  are  easily  explained.  Slowest  possible  delivery  is  to  Jx?  prac- 
tised. If  the  head  is  restrained  by  a  tight  cervix,  the  accoucheur  must  not  u.<e  force 
to  extract  it,  but  nuist  courage(nisly  all(»w  the  infant  to  die.  The  child  is  so  often 
already  lost  that  this  painful  advice  is  seldom  needed.  An  attempt  to  let  air  into 
the  child's  lungs  must  l)e  made  by  pulling  the  vagina  back  \\ith  a  sjM'culum.  and, 
after  cleansing  the  fauces,  depressing  the  jaw  with  the  fingers,  an  exiH'dient  which 
WcOS  reconnnended  by  Pugh,  in  17")4,  though  not  in  such  ca.><es. 

Should  ])lacenta  pnevia  occur  in  a  jjrimipara  or  in  others,  ami  the  cervix  be 
closed  .so  that  one  finger  may  not  be  introduced,  the  ca.'^e  becomes  more  formidable 
still.  For  such  patients  the  vaginal  tamix)n  and  the  coliMuirynter  have  U-en  recom- 
mended. There  are  real  objections  to  l)oth  on  the  score  of  .sepsis  and  ineffici»*ncy. 
Unless  the  head  is  firmly  engaged  ii\  the  jielvis.  the  tamp<m  will  not  exert  siifficient 
comi)res.sion  on  the  cervix  and  placenta  against  the  head  to  check  l)l«'«>ding  in  this 
manner.  Then  the  external  is  converted  into  an  internal  hemorrhage.  The  .>*ame 
is  true  of  the  colpeurynter.  I  have  never  failed  to  jvi.-^s  the  coljx'urynter  into  the 
uterus,  and  I  never  use  the  tamixni  excej^t  j^rovisionally.  during  the  transiM)rtation 
of  the  patient,  or  while  other  jireiiarations  are  being  completed.  It  is  for  these 
causes  that  cesarean  section  has  been  reconnnended. 

Treatment  During  the  Third  Stage.— Many  patients  have  Won  lost  at  this  iH)int. 
having  been  skilfully  carried  through  the  two  other  stages.  It  is  nece.s.<ary  to  s:ive 
blood  with  every  move.  As  .soon  as  the  child  is  deliven>d.  jis  in  ce.<*arean  s<'ction. 
it  is  handed  to  a  competent  a.«*sistant.  the  op<Tator  devoting  all  his  attention  t«)  the 
mother.  Even  a  moderate  hemorrhage  now  demands  the  inunediate  removal  of  the 
placenta.  Since  contraction  and  retraction  of  the  IhhI  of  the  plac<'nta  are  imfxTfect, 
and  especially  since  its  structure  may  be  pathologically  altered,  the  delivery  of  the 


400  THE    PATHOLOGY    OF    PREGXAXCY,    LABOR,    AND    THE    PUERPERIUM 

l)la(*eiita  is  slow  and  adherences  may  l)o  met  with,  some  of  which  are  so  tougii  that 
the  finger  cannot  break  them.  As  soon  as  the  placenta  is  removed  the  uterus  usually 
contracts  strongly  and  bleeding  ceases,  AVatch  closely,  jyidling  open  the  vagina  icith 
a  speculufn  to  see  if  blood  continues  to  escape  from  the  cervix,  and  if  it  does,  tampon  the 
whole  uterovaginal  tract  firmly.  Tl'a.s/e  no  precious  seconds  on  uncertain  methods 
of  hemostasis,  but  in  the  presence  of  such  urgent  symptoms  use  the  most  radical  and 
definitive  means  we  have.  During  the  ten  to  twenty  seconds  while  waiting  for  the 
gauze  hold  the  uterus  securely  in  forced  anteflexion  (Fig.  718).  (See  Treatment  of 
Postpartum  Hemorrhage,  p.  775.) 

In  placenta  previa  a  tiny  laceration  may  give  rise  to  a  fatal  bleeding.  The 
soft,  vascularized  cervix  is  difficult  to  hold  for  suturing,  and  it  ma}'  he  impossible 
to  sew  up  a  laceration  or  to  sew  it  up  quickly  enough  to  save  an  already  exsangui- 
nated woman.  In  suturing  a  laceration  of  the  cervix  it  is  necessary  to  expose  the 
field  thoroughly  by  broad  retractors  (Fig.  689).  The  lips  are  grasped  with  the 
vulsellum  forceps,  and  the  tear  j^rought  within  reach  of  the  needle.  Usually  the 
field  is  so  flooded  with  blood  that  it  is  impossil)le  to  see  where  to  sew.  A  bullet 
forceps  may  be  laid  temporarily  on  each  side  of  the  uterus,  seeking  to  secure  the 
uterine  arteries  in  the  bases  of  the  broad  ligaments  (lienkel).  In  one  such  case  I 
packed  the  uterus  and  the  rent  in  the  broad  ligament  firmly  with  gauze,  thus  stop- 
ping the  furious  flow,  after  which  the  lips  of  the  cer\'ix  were  united  over  the  tampon, 
thus  closing  up  the  uterus  entirely  (Fig.  725) .  The  vagina  was  snugly  packed  with 
dry  cotton,  to  exert  counterpressure.  The  sutures  were  removed  the  next  day  and 
the  gauze  two  days  later.     The  patient  recovered. 

Before,  during,  and  after  delivery  in  cases  of  placenta  prsevia  it  is  often  neces- 
sary to  treat  the  anemia.  If  the  mother  has  lost  much  blood,  give  her  saline  solu- 
tion under  the  skin,  not  per  rectum,  as  this  interferes  with  the  asepsis  of  the  local 
treatment.  When  the  bowels  are  moving  over  the  field  of  operation,  it  may  be  im- 
possible to  avoid  carrying  the  discharges  into  the  uterus.  Saline  solution  is  to  be 
given  even  if  the  hemorrhage  is  going  on,  as  then  the  patient  does  not  lose  pure 
blood,  but  blood  mixed  with  salt  solution.  We  do  not  wait  for  fainting  to  stop  the 
hemorrhage  in  placenta  prsevia.  The  author  has  administered  a  gallon  of  saline 
solution  under  the  sldn  and  it  was  absorbed  as  fast  as  it  could  be  injected,  and,  after 
the  local  treatment  of  the  case  was  completed,  two  quarts  more  per  rectum,  with 
success.     Such  large  amounts  are  seldom  required. 

Other  Methods  of  Treatment. — Accouchement  force,  the  rapid  dilatation  of  the 
cervix,  tearing  and  cutting  it,  if  necessary,  followed  by  the  immediate  delivery  of  the 
child,  has  no  place  in  the  treatment  of  placenta  prsevia.  The  author  believes  it  is 
almost  criminal,  and  it  is  opposed  to  all  recognized  principles  of  treatment.  The 
results  condemn  it,  and  Kerr  says,  judging  from  mortalities,  it  is  the  worst  of  all 
methods.  Treub  retracts  his  recommendation  of  it,  saying  that  his  mortality  was 
18.25  per  cent,  for  the  mothers  and  48  per  cent,  for  the  children.  IMiiller  showed 
44  per  cent,  maternal  mortality  and  ()2.7  per  cent,  for  the  children.  Gentle  dilata- 
tion is  wanted,  for  even  the  soft-rubl^er  bag  may  rupture  the  C(n-vix  unless  properly 
handled. 

The  same  may  be  said  of  Bossi's  branched  ]iowerful  steel  dilator  and  of  the 
others  of  the  class. 

Separation  of  the  placenta,  or  its  r(>moval  Ijcfore  delivery  of  tlie  child  (Simpson, 
1840),  is  obsolete.  ]\Iiller,  of  Pittsburgh,  ligated  the  uterine  arteries  in  11  cases, 
saving  the  first  and  last  eight  of  them. 

Cesarean  section,  first  performed  by  Tait,  is  gradually  gaining  reluctant  recog- 
nition. Especially  favored  by  American  surgeons  and  gynecologists,  it  was  con- 
demned by  American  and  European  obstetricians, — Ehrenfest,  Hirst,  Holmes, 
Schauta,  Hofmeier,  Ahlfeld, — but  very  recently  the  operation  has  b(>gun  to  enjoy 
more,  and  I  think  just,  popularity.     Williams  and  Edgar  give  it  qualified  approval,

Siiiitli,  Bar,  Rccasciis  (Madrid)  rccoiimicnd  it — (jf  cours*'.  in  wcli-clKjscn  cases.  At 
tlic  uu'ctinf?  of  the  Aiuerieaii  (lyneeoloKie  Society,  April,  IIMJ'J,  the  .subject  was 
thoroughly  handled,  and  while  the  opinioiLS  were  divided,  a  perusal  of  the  transac- 
tions is  convincing  that  cesarean  section,  in  the  hands  of  the  expert  abdominal 
operator,  is  a  \aluai)le  addition  to  our  treatment.  Cesarean  section  has  a  genj-ral 
mortality  of  4  jier  cent,  in  favoral)le  cases;  it  siiould  he  no  more  than  this  in  favor- 
able cases  of  placenta  prievia,  and  there  is,  in  addition,  the  reduction  of  the  infant 
mortality  from  50  to  5  per  cent.  Placenta  praevia,  un<ler  the  usual  methwls,  shows 
at  best  4  per  cent,  mortality,  and  its  treatment  entails  great  anxir-ty,  much  loss  of 
time,  and  retjuires  exceptional  ol)stetric  skill  to  save  both  mother  and  child.  In 
the  isthmial  variety,  where  the  j)lacenta  is  imi)lanted  s(|Uarely  over  the  int<'rnal  os 
andhangslike  a  festoon  aboveit,thematernalmortalityis  .so  highthat  the  alxlominal 
delivery  is  strongly  the  method  of  choice,  \\ithout  going  furth«'r  into  the  di.scu.s- 
sion,  I  will  state  my  ])osition:  an  indication  for  <'esarean  section  will  arise  in  ca.s<»s 
of  central  and  of  partial  i:)laceuta  ])ra'via,  wiien  the  pregnancy  is  at  or  near  tenn, 
with  a  living  child,  the  mother  in  good  contlition,  the  cervix  being  closed  or  promis- 
ing difficulty  in  dilatation,  contlitions  most  connnon  in  primiparie.  A  necessary 
re(iuirement  also  is  that  the  aseptic  facilities  of  a  good  maternity  can  be  had,  or 
improvised  at  home,  and  a  man  cai)al)le  of  his  task  is  obtainable.  TIk-  opjxirtuni- 
ties  for  ])erforming  the  abdominal  delivery  with  ail  these  conditions  filled  will  Im- 
(luite  rare. 

In  the  exigencies'of  general  jiractice,  and  in  the  usual  bad  surroimdings  in 
which  the.se  cases  come  to  the  accouclieur,  it  is  found  that  the  best  method  <»f  treat- 
ment is  Ikaxton-Hicks'  version  and  very  slow  spontaneous  delivery.  Next  comes 
the  metreurynter. 

\'aginal  cesarean  section  was  performed  by  Diihrssen  and  is  recommended  by 
Bumm  for  placenta  pra^via.  It  is  condemned  by  most  writers,  among  whom  are 
Kerr,  Spencer,  Peterson,  Xewell,  Ilofmeier,  Ilannes.  I  have  done  it  once  with  suc- 
cess, when  the  ])lacenta  was  low  in  the  uterus  and  had  i)artly  sei)arate<l,  l»ut  believe 
that  the  operation  is  not  to  be  reconnneniled  in  the  treatment  of  placenta  pra'via. 

Very  recently  extraperitoneal,  suprasjiiiphyseal  cesarean  section  has  been  ad- 
vocated for  these  cases  (Sellhcim).  The  author  has  no  experience  with  the  oj>era- 
tion,  l)ut  from  i)ublished  reports  believes  that  the  indication  will  receive  scant 
recognition.

CHAPTER  XXXV 


MULTIPLE  PREGNANCY 


Placing  this  su])ject  in  the  pathology  of  pregnancy  might  ehcit  comment,  but 
the  succeechng  pages,  sho^^^ng  the  frequency  of  maternal  disease  and  of  fetal  death, 
will  prove  that,  in  the  human  female,  having  more  than  one  offspring  at  a  time  is 
distinctly  abnormal.  It  is  an  ata\'istic  reversion,  and,  in  general,  such  reversions 
are  abnormal.  Twins  occur,  according  to  Guzzoni,  who  studied  over  50,000,000 
births,  once  in  87  cases,  triplets  once  in  7103;  quadruplets  once  in  757,000;  quin- 
tuplets once  in  41,600,000  births.  Over  30  cases  of  quintuplets  have  been  reported. 
Vassali  reports  an  authentic  case  of  sextuplets,  at  Lake  Lugano,  there  being  de- 
livered at  the  fourth  month  two 
female  and  four  male  children 
with  a  total  weight  of  1730  gm. 

The  frequency  of  multiple 
pregnancy  varies  with  the  fertil- 
ity of  the  people  (Peuch,  1873), 
and  the  fertility  varies  in  different 
countries  and  at  different  periods; 
thus  in  Ireland  and  Russia  twin 
births  are  commoner  than  in 
France,  where  the  birth-rate  is 
low. 

Multiparae,  especially  those 
giving  birth  frequenth',  are  more 
likely  to  have  twins,  and  the  prob- 
ability increases  after  the  age  of 
thirty-three  3'ears  in  both  par- 
ents. A  hereditary  disposition 
is  certain,  and  the  tendency, 
while  usually  transmitted  by 
the  mother,  may  also  be  given 
through  the  father.  It  is  also 
noted  in  the  lower  uniparous  ani- 
mals, for  example,  the  cow  (Dun- 
can) .  Marriage  of  twins  increases 
the  potency  of  the  hereditary  im- 
pulse. Twins  and  triplets  are 
likely  to  be  repeated  in  the  same 
family.  Cases  of  unusual  fertility  are  not  rare.  Geisler  tells  of  a  woman  physician 
(Mary  Austin)  who,  in  thirty-three  years'  wedlock,  had  13  twin  and  6  triplet  births, 
a  total  of  44  children,  her  sisters  having  41  and  26  children  respectively  (Strassman). 
Sue  tells  of  a  Parisian  whose  wife  bore  him  21  children  in  seven  years,  and  who 
seduced  a  servant  who  then  delivered  triplets. 

Causation. — Generally,  two  kinds  of  twins  are  distinguished,  those  coming 
from  separate  and  distinct  ova  and  those  from  one  ovum.  Two  eggs  escaping  from 
an  ovary  at  the  same  time  may  be  fertilized  and  develop  synchronously  in  the  uterus. 
These  eggs  may  even  come  out  of  the  same  Graafian  follicle,  since  such  follicles,

and  even  some  containing  three  eggs,  have  fnciucntly  heen  seen.  Each  ovary  may 
furnisli  one  of  the  ova.  When  t\v(j  or  more  separate  ova  locate  in  the  uterus,  we 
have(hstinct  (jvular  formati(jns  deveiopiiigside  hy  side  (Fig.  419).  If  tlieova  locate 
far  from  each  other,  two  distinct  placenta.s  develop;  if  near  each  other,  the  two  pla- 
centas fu.se,  but  their  circulations  tlo  not  (Schatz).  Since  in  such  ca.ses  each  child 
lias  its  own  amnion  and  chorion,  where  the  membranes  lie  apjxjsed  a  septum  will 
be  found  made  up  of  four  layers — an  amnion  and  a  chorion  for  each  fetus.  Ocea- 
sionally  decidual  remnants  will  be  found  in  the  se|)tum,  the  relics  of  the  decidua* 
caixsulares  or  reflexa?  of  the  early  stages  of  the  development  of  the  ova.  Theoreti- 
cally, one  might  in.si.st  on  finding  six  layers  in  the  septum  of  dcjuble  ovum  twin.s— 
two  decidual,  two  chorions,  and  two  anmions. 

The  etiology  of  twins  from  one  ovum,  called  homologous,  or  monoeh(jrionic, 
is  still  a  mystery.  Aristotle  knew  that  two  embr3os  could  come  from  an  egg  with 
two  yolks,  antl  three  eml)ryos 
have  been  found  in  one  egg.  Two 
nuclei  have  been  found  in  one 
yolk,  and  Kolliker,  Stockel,  and 
von  Franciue  found  double  ger- 
minal vesicles  in  the  hmnan  egg. 
If  such  an  ovum  is  to  be  fertil- 
ized, two  ])olar  l)odies  must  first 
be  extruded,  and  two  spermato- 
zoiils  are  needed  for  fertilization, 
which  theoretically  is  not  imjios- 
sible,  but  then  we  would  have 
two  chorions  develoix'd  and  the 
fintlings  would  be  the  same  as  if 
two  different  eggs  had  been  im- 
jiregnated.  Perhaps  we  shall 
learn  hereafter  that  such  an  oc- 
currence has  been  proved.  An- 
other theory  is  that  on  one 
germinal  vesicle  two  primitive 
streaks  develop,  that  is,  double 
gastrulation  occurs.  Two  sper- 
matozoids  entering  the  ovum 
probably  cannot  produce  this 
condition,  because  ova  fertilized 
in  this  way  usually  die. 

If  the  two  embryonal  spots 
develop  close  to  each  other,  it 
is  possible  that  one  amnion  will 

inclose  the  two  fetu.ses;  if  far  from  each  other,  each  fetus  will  ha\e  a  sej)arate 
amnion  (Fig.  420).  The  older  writers  held  that  always  two  anmions  dev«'loped, 
but  that  the  septum  atrophied  and  disappeared.  Only  about  40  ca.ses  are  on 
record  of  twins  without  a  .septum  between  the  two  sacs,  that  is,  lying  in  one 
amniotic  cavity.  Should  the  separation  of  the  two  embryonal  areas  lx»  incomplete, 
a  (loul)le  mcmster  will  result  (Sol)otta);  therefore,  according  to  the  theory  that 
homologous  twins  are  the  result  of  the  fission  of  the  embryonal  area  into  two  parts, 
and  their  .separate  development  into  fully  formed  fetuses,  we  nnist  conclude  that 
double  monsters,  like  the  Siamese  twins,  are  the  result  of  incomplete  li.ssion  and  not 
of  fusion.  A  monster  with  four  legs  would  mean  fission  at  the  lower  ix)Ie,  and  one 
with  two  heads  fission  at  the  cephalic  i>ole  of  the  (Mnbryonal  area.  It  is  regretahle 
that  we  have  little  .seientihc  foundation  for  the.se  i)lausible  theori<-s.

THE    PATHOLOGY   OF    PREGNANCY,    LABOR,    AND    THE   PUERPERIUM 


Characteristics. — The  i)lat'enta  in  uniovnl  twins  is  ahva^'s  single;  there  are 
usually  two  cords,  but  rarely  only  one  which  bifurcates  near  the  f(^tuses,  and  these 
are  monoamniotic  ova;  the  blood-vessels  anastomose  on  the  surface  of  the  placenta, 
and  also  in  the  villi  themselves,  producing  a  third  or  intermediate  circulation  be- 
tween the  t^^^ns.  The  septum  of  the  placenta  never  shows  traces  of  decidua,  and 
only  two  layers,  the  two  amnions,  can  be  found  in  it.  The  children  are  said  to  be 
very  much  alike  in  size  and  in  mental  and  physical  characteristics,  Init  the  author 
has  not  found  this  to  be  constant.  Unioval  twins  are  rare,  Ahlfeld  in  1157  cases 
finding  only  15.55  per  cent. 

Triplets  and  even  quadruplets  may  come  all  from  one  ovum,  but  usually  two 
ova  are  concerned,  one  of  which  may  bring  forth  two  fetuses. 

In  length  and  weight  twins  usually  differ  more  or  less,  4  cm.  and  2200  gm. 


Fig.  421. — Acardiacus  Amouphds.     (Northwestern  University  Medical  School  specimen.) 


being  the  limits  respectively.  Twins  are  usually  smaller  than  single  children,  but 
the  combined  weight  is  greater.  The  same  ]ir()portion  of  boys  and  girls  obtains 
with  twins  as  in  general.  Twins  from  one  ovum  are  smaller  than  those  from  two, 
and  the  difference  in  weight  is  not  so  great ;  also  they  have  a  higher  mortality  and 
are  more  often  deformed.  The  same  deformity  often  exists  in  both  twins,  as  in 
one  of  the  author's  cases,  double  harelip,  and  one  of  C.  E.  Black,  rudimentary  colon. 
It  is  said  the  tendency  to  this  form  of  twins  is  not  hereditary  (Strassman).  Eclamp- 
sia is  more  common  with  unioval  twins.  Homologous  twins  are  always  of  the  same 
sex.  The  two  circulations  anastomose  in  the  common  placenta,  artery  to  artery, 
vein  to  vein,  and  artery  to  vein  through  the  third  circulation,  the  intercommunicat- 
ing villus  tree.  The  anastomosis  of  the  two  blood  systems  was  known  to  Portal, 
who,  therefore,  advised  the  tying  of  the  cord  of  the  first  child  delivered  to  prevent 
the  other  from  bleeding  through  the  open  vessels.     As  a  result  of  this  arrangement

many  anomalies  arise  out  of  the  unctiual  distrihution  and  .size  of  tlie  placental 
vessels  and  unequal  nutritional  eonditions.  The  heart  of  one  child,  because  of  its 
better  nourishment,  may  overpower  that  of  the  other  throunh  the  aniistomotic 
vessels.  If  this  occurs  at  an  early  period,  the  weaker  heart  dilates  into  a  tortuous 
vessel,  the  fetus  remains  undeveloped  and  becomes  a  parasite  on  its  stronger  brother 
(Fig.  421).  It  is  called  an  acardiacus.  If  one  fetus  dies  after  being  fully  developed 
and  is  long  retained  in  the  uterus,  it  is  changed  into  a  fa'tus  compre.ssu.s  (Fig.  422). 
Sometimes  the  stronger  fetus  causes  a  polyhydranmion,  according  to  Stra.s>^man, 
because  its  hypertrophied  heart  and  kidneys  produce  more  urine,  while  the  weaker 
suffers  from  oligohydramnion.  Polyhydranmion  is  so  common  with  twins  that 
when  it  is  discovered,  the  existence  of  tlie  latter  is  to  be  su.spected.  If  the  twins  lie 
in  one  amniotic  cavity,  the  two  umbilical  cords  may  be  twisted,  causing  the  death 
of  one  or  both  fetuses. 

Dichorionic  or  double-ovum  twins  are  also  subject  to  abnormalities.  One 
fetus  may  die  and  be  expelled,  the  other  gciing  normally  to  term.  The  author  de- 
livered a  woman  at  term  of  twins,  and  she  stated  that  five  months  previcnisly  she 
had  had,  in  New  York  city,  an 
abortion  of  four  months.  Again 
the  dead  fetus  may  l)e  retained, 
and  the  lifjuor  amnii  l)eing  ab- 
sorbed, it  is  flattenetl  against 
the  wall  of  the  uterus,  a  dry, 
shrunken  mass  (Fig.  422).  It 
may  present  i)efore  the  normal 
fetus,  giving  rise  to  diagnostic 
errors,  and  it  may  be  lost  in  the 
uterus  after  delivery  of  the  pla- 
centa and  cause  ])uerperal  infec- 
tion and  late  hemorrhages.  The 
placenta  of  the  compressed  fetus 
is  white,  hard,  fibrous,  infarcted, 
and  demarked  sharply  fn^m  that  of  tlie  normal  fetus,  and  this  finding  on  the 
placenta  will  arouse  the  suspicion  of  the  accoucheur  that  another  fetus  has  l)een 
retained  in  utero. 

Superfetalion  is  the  nesting  of  a  second  fetus  in  the  uterus  already  oceupie<l  by  one  in  the 
process  of  development.  Its  oeeurrcnce  has  been  held  possible  by  .Vincrican  and  Kn-neh  auth<»rs, 
while  the  English  and  German  writers  usually  deny  it.  .\  iloublc  uterus  may  earry  a  child  in 
each  (•()mi)artnient,  as  in  the  ca.-ics  (luotc*!  by  Ham.><b()tham — one,  where  a  woman,  live  months 
an<l  sixteen  days  after  tlie  deli\'ery  of  a  li\ing  seven  months'  child,  deli\(reil  another  of  full 
development,  and  another  where  two  well-formed,  fully  developeii  boys  were  boni  thn-*-  months) 
apart.  These  cases  should  not  be  called  superfetalion.  Since  the  decidua  reflexa  does  not 
unite  with  the  vera  until  the  middle  of  the  fourth  month,  and  since  ovulation  occurs  during 
pregnancy,  theoretically  superfetation  is  po.<.sible,  but  in  most  in.stances  caimot  l)e  nroveii.  Dif- 
ferences in  the  size  of  the  fetu.«es  may  be  explaine<l  by  une(jual  devi-lopment,  but  I-.T.  .\ndn«ws, 
Harry,  and  the  author  have  .seen  specimens  which  prove  the  occurrence  of  suiH-rfetation  in  the 
human  female.  Dr.  Zimmerman,  of  Cameron,  Illinois,  found  a  healthy  ovinn  of  four  w«i'k!», 
together  with  a  healthy  fetus  of  ten  we<'ks,  in  an  abort «h1  niikss.  .\  .s|H'cimen  Wius  shown  to  the

Sui>erfiTunilalion  is  the  impregnation  of  two  difTerent  ova,  abt)Ut  the  same  time,  by  .spcnna 
from  different  fathers.  Its  occurrence  in  animals  is  i)rove<l,  but  though  dnul)t«><l  for  the  hum.an, 
is  possible.  .\  negro  woman  gave  birth  to  a  black  and  a  mulatto  child,  .ifter  inten-ours*-  with  a

heads  are  apposed,  they  may  be  faceted.  In  one  of  tlie  author's  cases  the  flatten- 
ing of  the  foreheads  of  the  eliildren  was  noticeable  after  several  years. 

If  one  placenta  lies  above  the  other,  it  is  not  rare  U>  find  the  lower  edge  of  the 
common  placenta  near  or  over  the  internal  os.  Placenta  pra-via  with  twins  en- 
dangers three  lives.  Transverse  and  breech  presentations  are  favored  by  the  low 
implantation  of  the  connnon  placenta. 

Owing  to  the  shape  of  the  uterus,  the  child  lying  in  its  left  half  usually  is  lower 
and  jiresents  and  is  deliv^ered  first.  The  uterine  muscle  now  has  a  chance  to  shorten 
and  get  a  better  grip  on  its  contents.  Another  bag  of  waters  f<jrms,  rui)tures,  and 
the  second  fetus  is  extruded,  usually  more  (|uickly  than  the  first,  because  the  nmscle 
is  stronger  and  there  is  no  resistance  from  tlie  scjft  ])arts.  The  interval  l»etween  the 
deliveries  varies  from  a  few  minutes  to  forty-four  days  (C'arscjn).  Reference  has 
alreadv  been  made  to  the  al:)ortion  of  one  twin  while  the  other  was  carried  to  term.

It  is  impossible  to  show  by  figures  the  natural  interval  iM'tween  the  two  births,  lx»- 
cause,  as  a  rule,  the  accoucheur  ha.stens  the  seconil  delivcTy.  Isually  the  siu-ond 
child  follows  the  first  after  thirty  to  forty  minutes.  In  one  of  the  author's  cases 
the  head  of  the  second  followed  the  feet  of  the  first. 

Now,  tlie  uterus  contracts  firmly  down  on  the  placenta,  and  in  a  small  majority 
of  cases  the  tiiird  stage  is  natural.  Hemorrhage,  however,  is  more  jmtfus<'  and  the 
after-pains  are  harder. 

Diagnosis  of  Twins. — \'(  ry  rarely  has  the  diagnosis  of  triplets  been  made  before 
delivery.  Pinard,  of  Paris,  and  Fletdu  r  Hell,  among  others,  did  it.  Twins  may 
almost  always  l)e  diagnosed  during  pregnancy  if  the  examiner  is  sufficiently  atten- 
tive. Extremely  large  and  glol)ular  belly,  rajiid  growih  of  the  uterus,  marke<l 
edema,  albuminuria,  motion  felt  all  over  the  abdomen,  excite  the  interest  of  the 
accoucheur  and  warn  to  greater  care.     The  diagnostic  |)oints  are:

THE  PATHOLOGY  OF  PREGNANCY,  LABOR.  AND  THE  PUERPERIUM 


1.  A  sulcus  felt  in  the  fundus  or  down  the  front  of  the  uterus.  This  may  occur 
in  uterus  arcuatus  or  distorted  uteri,  or  even  in  ordinary  labor,  and  may  be  absent 
in  twins. 

2.  Unusually  large  and  globular  uterus,  IMust  eliminate  hj'dramnion  and 
large  child. 

3.  Palpation  of  three  large  parts — two  heads  and  one  breech  or  two  breeches 
and  one  head.  Make  no  diagnosis  on  the  multiplicity  of  small  i)arts, — the  extremi- 
ties,^because  the  child  can  place  these  in  many  locations. 

4.  AMien  one  head  is  in  the  pelvis  and  the  distance  from  this  to  the  other  large 
part  in  the  funtlus  is  too  great  to  be  the  length  of  one  fetus,  for  example,  over  30  cm. 


Fig.  425. — Twins  Side  by  Side. 

5.  Auscultation  of  two  sets  of  fetal  heart-tones,  with  these  characteristics: 
(1)  Both  asynchronous  with  the  maternal  pulse;  (2)  they  must  be  asynchronous 
with  each  other,  the  difference  being  more  than  eight  beats;  (3)  there  must  be  a 
free  zone  between  the  two  areas  of  greatest  intensity.  It  is  best  for  two  qualified 
observers  to  listen  at  the  same  time;  in  doulitful  cases  it  is  well  to  use  a  stop-watch 
and  take  the  average  of  many  counts,  and  during  the  examination  the  patient  may 
not  change  her  position  (Fig.  426) . 


If  one  fhild  is  dead,  this  method  loaves  us  in  doubt ;  apain  the  two  hearts  may  beat  syn- 
chronou.sly  for  a  time.  The  author  in  one  sueh  ease  irritated  the  infant  until  it  nioveil,  which 
accelerated  the  heart-beat.  A  child  with  straif^htened  spine,  as  in  the  military  attitude,  may  have 
heart-tones  audible  on  both  sides  of  the  uterus,  or  the  placenta  may  divide  the  area  of  audibility. 
Hearing  two  loud  uterine  souffles  is  not  conclusive,  nor  is  hearing  one  fetal  souffle  and  one  fetal 
heart-sound.  During  labor  one  may  hear  normal  heart-tones  and  feel  a  pulseless  cord  in  the 
vagina,  but  oven  this  is  not  positive,  because  the  cord  may  l)e  compressed  temporarily  while  the 
heart  goes  on  beating.     Of  course,  such  a  condition  .soon  kills  the  infant.

S.   Palpation  of  two  large  parts  by  the  vaginal  examination. 

\).  The  .r-ray  may  now  be  used,  and  its  demonstration  of  two  fetuses  is  positive. 
Edling,  of  Malmoe,  showed  three  in  one  case. 

If  the  diagnosis  is  made  during  pregnancy,  it  is  best  not  to  tell  the  mother,  but 
to  ac(iuaint  the  father  with  the  facts,  to  save  the  one  from  fear  ami  worry  an<l  yet  to 
protect  the  accoucheur  from  the  imputation  of  ignorance.  After  the  delivery  (jf 
one  child  the  diagnosis  that  another 
remains  in  the  uterus  is  easily  made 
by  one  grasp  of  the  fundus. 

Differential  Diagnosis.-  In  the 
early  months  the  jiresence  of  twins 
may,  by  distorting  the  uterus,  give 
rise  to  the  suspicion  of  ectopic  gesta- 
tion. The  differential  diagnosis  of 
simultaneous  extra-  and  intra-uter- 
ine  pregnancy  from  ordinary  twins  is 
possible  only  to  a  keen  and  exjxT- 
ienced  obstetric  hand,  and  even  un- 
der most  favorable  circumstances  is 
rarely  made  before  ojx'ration. 

Polyhydramnion  often  com])li- 
cates  twins,  and  one  needs  to  shut 
out  ovarian  tumor  in  these  instances. 
(See  p.  .502.) 

Fil)roid  tumors  complicating 
pregnancy  may  simulate  ])lural  ges- 
tation to  perfection.  The  absence 
of  two  heart-beats  ujjon  repeated 
examinations;  the  inini()l)ility  of  the 
supposed  large  and  small  parts;  their 
constancy  of  location;  the  history  of 
fibroid — usually  allow  prompt  differ- 
entiation. After  delivery  the  ri])roi(ls 
may  lead  to  error  unless  the  cavity  of 
the  uterus  is  explored. 

Prognosis. — As  was  said  at  the  beginning  of  this  chapter,  plural  gestation  is 
not  normal.  Th(>  disturbances  of  j)regnancy  are  more  connnon,  and  their  fatality 
increased,  this  luring  esix'cially  true  of  the  toxemias  resulting  in  eclami)sia.  Heart 
disease  comjilicating  twin  ])regnancy  is  very  sitIous,  and  usually  indicates  the  induc- 
tion of  premature  labor.  In  one  of  the  author's  ca.ses  the  ana.-^arca  was  tremendous, 
hydropleura  and  li>-dropericardium  developing,  the  patient  having  hemoptysis  and 
dying  of  acute  edema  of  the  lungs.  Owing  to  the  longer  labors  and  the  more  fre- 
quent necessity  for  ojierative  deliveries,  sepsis  is  more  likely  to  occur,  and  the  opera- 
tive traumatisms  must  also  be  reckoned  in.  Postpartum  hemorrhage  occurs  nftener, 
and  it,  with  the  danger  of  infection  from  the  usual  metluHls  of  combating  it.  nuist 
also  be  included. 

For  the  child  the  jirognosis  is  serious.  Since  the  majority  of  twin  births  are 
premature,  many  infants  die  of  atelecta.«<is  and  general  del)ility.  .\  certain  numl)er 
of  the  second  children  are  lost  during  the  interval  after  the  tirst  is  lM)rn.  from  abrujv 
tion  of  the  common  jilacenta.  and  not  a  few  die  during  ojxTative  (h'livcries.     After

birth  the  mother  maj'  be  too  ill  or  too  weak  i)roperly  to  eare  for  them,  or  she  may 
have  insufficient  milk,  and  these,  coupled  with  congenital  debility,  explain  the  high 
mortality  in  the  first  year  of  life.  Ahlfeld  }:»laces  it  at  75  per  cent.,  but  the  author 
thinks  this  is  too  high.  Triplets  and  quadruplets,  of  course,  offer  much  higher 
mortalities. 

Many  mothers  ask  if  twin  children  are  mentalh'  and  phj'sically  as  strong  as 
those  of  single  birth.     The  author  has  carefully  studied  his  cases  and  other  twins, 


Fig,  427. — Interlocked  Twins, 


and  finds  that  all  depends  on  the  degree  of  prematurity.     "Where  the  children  were 
fully  developed,  no  difTerence  could  be  noted. 

Treatment. — During  pregnancy,  a  pluriparient  woman  requires  greater  watch- 
fulness, especially  regarding  her  kidneys  and  circulation.  Should  she  abort,  the 
accoucheur  must  see  that  the  uterus  is  empty.  Although  cases  are  on  record  of  the 
successful  carrying  of  the  second  fetus  to  term,  the  frequency  of  infection  of  the 
partially  emptied  uterine  cavity  is  so  great  that  the  danger  should  not  be  assumed 
on  so  slim  a  chance  of  saving  the  child.  During  labor  "watchful  expectancy"  is 
practised.  One  must  not  be  deceived  by  the  false  pains  of  the  latter  weeks  into  as- 
suming that  labor  has  actually  begun.  Wait,  if  possible,  for  complete  dilatation 
before  rupturing  the  bag  of  waters.  With  frequent  auscultation  the  accoucheur 
watches  the  welfare  of  the  two  children.     It  is  wise  not  to  let  the  first  stage  drag  on 


MULTIPLE    PREGNANCY

too  long,  because  inroads  on  the  parturient's  strength  may  be  regretted  in  the  third 
stage,  when  hemorrhage  may  set  in.  Preparations  for  operative  delivery  and  for 
the  treatment  of  a  pathologic  third  stage  must  be  complete. 

After  the  first  infant  is  delivered  a  careful  ext<rnal  and  internal  examination 
will  enable  the  accoucheur  to  decide  on  tlie  ])n)i)er  treatment.  The  cord  should  be 
clami)e(l  or  tied  on  its  placental  end.  Should  the  cord  of  the  second  child  prolapse — 
.should  the  shoulder  present,  immediate  action  is  required— in  short,  any  abnor- 
mality is  to  be  rectified.  The  delivery  (jf  the  second  twin  by  versicjn  an«l  extraction 
or  forceps,  or  even  simple  Ivristeller  exprcasiou,  is  usually  easy,  because  the  soft

parts  have  been  prepared  by  the  transit  of  the  first  infant.  If  the  heart-tones  are 
normal, — and  one  should  listen  constantly. — if  there  is  neith(>r  external  nor  internal 
hemorrhage,  one  may  safely  wait  for  twenty  minutes  before  rujituring  the  s(>contl  bag 
of  waters.  This  interval  allows  the  uterus  to  gather  strength  for  the  expulsion  of 
the  second  child,  and  is  also  a  safeguard  against  po.><tpartum  hemorrhage. 

Owing  to  the  overdistention  of  the  uterus,  contraction  and  retraction  of  its 
muscle  are  j>oor  and  the  tendency  to  postpartum  hemorrhage  is  augmented.  Accu- 
rate control  of  the  funtlus  and  gentle  ma.<sage  are  indicated,  and  expression  of  the 
placenta  is  usually  needed  earlier  than  in  single  lalmrs.  Ergot  should  lx»  given  as  soon 
as  the  placentas  are  born,  and  repeated  in  smaller  dost\s  for  a  week  or  more,  Ix'cause 


472      THE  PATHOLOGY  OF  PREGNANCY,  LABOR,  AND  THE  PUERPERIUM 

involution  of  the  uterus  is  slower.  The  aeeoueheur  should  remain  in  the  house 
several  hours  to  be  certain  that  no  relaxation  of  the  uterus  may  occur,  and  to  dis- 
cover any  tendency  to  post])artum  eclampsia. 

Anomalies  of  Plural  Births. — (1)  Pathologic  presentations — shoulder,  breech,  brow,  face, 
anterior  parietal  bone,  etc. — occur  in  a  goodly  percentage  of  cases,  and  are  treated  on  general 
principles. 

(2)  The  part  presenting  may  change  several  times  before  one  finally  engages  and  is  delivered. 
A\'atch  for  pathogenic  delay,  then  interfere. 

(3)  The  bag  of  waters  of  the  .second  cMld  may  rupture  before  that  of  the  first,  or  the  two 
may  rupture  at  one  time.  No  treatment  is  necessary  in  the  first  instance  unless  the  cord  of  the 
second  child  prolapses  before  the  presenting  part  of  the  second  is  delivered.  If  conditions  for 
extraction  are  filled,  deliver  both  children,  otherwise  replace  the  cord. 

(4)  Rarely  the  placenta  of  the  first  twin  is  delivered  before  the  second  is  born.  If  the 
placenta  is  independent  of  the  other,  no  harm  results  from  this,  but  if  the  two  are  united,  the 
necessary  abruption  of  the  placenta  of  the  second  child  will  be  fatal  to  it  unless  it  is  delivered 
at  once.  The  signs  of  asphyxia  and  external  hemorrhage  apprise  the  accoucheur  as  to  what  is 
going  on.     Rapid  delivery  of  the  second  child  will  save  it,  and  also  preserve  the  mother. 

(5)  The  transit  of  the  first  child  may  alter  the  position  of  the  second,  for  example,  from 
longitudinal  to  transverse,  from  vertex  to  face.     Treatment  is  on  general  lines. 

(6)  Interlocking  or  collision  may  occur.  The  two  heads  may  try  to  enter  the  pelvis  at  the 
same  time,  or  one  head  enters,  while  the  second  head,  caught  in  the  neck  of  the  first  twin, 
attempts  to  enter  with  it  (Fig.  427).  If  the  children  are  small,  such  a  mechanism  is  possible. 
Or  the  head  of  the  second  fetus  enters  the  pelvis  after  the  first  one,  presenting  by  the  breech,  has 
been  delivered  as  far  as  the  neck  (Fig.  428).  The  second  child,  coming  as  a  breech,  may  straddle 
the  first  in  shoulder  presentation,  or  four  extremities  may  present,  the  two  breeches  entering  the 
inlet  at  once. 

Delay  in  the  delivery  of  twins  should  always  excite  the  suspicion  of  locking, 
and  an  examination  with  the  whole  hand,  in  narcosis,  if  needed,  is  to  be  made. 
IMuch  can  be  accomplished  by  manipulation,  especially  if  the  uterus  is  paralyzed 
by  deep  anesthesia,  and  the  children  may  be  disentangled,  one  of  them  being  led 
into  the  pelvis.  Should  interlocking,  as  in  Fig.  428,  occur,  a  deep  episiotomy  is 
done,  to  avoid  complete  laceration  of  the  perineum,  the  whole  hand  inserted,  and 
the  second  head  pushed  up  and  out  of  the  pelvis.  If  the  heads  are  small,  such  a 
procedure  is  possible;  if  not,  one  should  decapitate  the  first  child  cjuickly  and  push 
its  head  up  into  the  uterus,  then  deliver  the  second  with  forceps.  In  such  a  case 
Lobenstine  did  a  cesarean  section  and  saved  both  twnns  and  mother.  Forceps  or 
the  cranioclast  may  be  applied  to  the  second  child,  delivering  it  first,  but  one  should 
attempt  to  save  at  least  one  of  the  children  bj'  disentangling  them  under  deep 
anesthesia.     If  the  first  one  is  dead,  there  is  no  occasion  for  hurry.

PROLONGED  PREGNANCY  AND  MISSED  LABOR 

Reference  lias  Ix'cn  made  to  jJi-cjlunKcd  pregnancy  (p.  112i,anfl  hero  will 
be  considered  tiie  ])atliologif  siile.  Lalior  ofca-sionally  In-giiLs  at  tiie  projxT  iK'riod, 
some  degree  of  dilatation  is  attained,  but  for  some  reason  the  pains  cease  and  ges- 
tation continues  for  from  two  to  four  weeks,  when  the  uterus  again  is  set  in  action 
and  delivery  is  accomplished.  This  occurrence  must  n(jt  l>e  confounded  with  the 
jxiins  and  changes  in  tiie  cervix  which  sometimes  <jccur  at  "ligiitening."  When 
the  child  is  thus  carried  over  term,  it  undergoes  certain  alterations;  the  length  in- 
creases disproportionately  to  the  weight,  the  head  enlarges,  and  the  bones  harden, 
the  parietal  l)osses  becoming  prominent  and  pointed.  The  body  is  less  fat  and  is 
firmer  in  consistence;  the  si)inal  column  is  harder  and  less  flexible.  In  some  ca.se.s 
the  fetus  is  overgrown  in  every  way.  ( )ligoliydranmion,  with  its  conse(iuences,  may 
occur.  The  child  may  die  without  other  cause  ajjparently  than  Ix'ing  overriiH", 
and  this  fact  is  known  and  appreciated  even  ]>y  the  laity. 

During  labor  I  have  observed  these  anomalies: 

1.  Lack  of  cephalic  molding,  from  the  extreme  ossification;  high  arrest  of  head; 
prolonged  and  fruitless  labor;  forceps — hard  extraction;  extensive  injuries;  still- 
births. 

2.  Occipitoposterior  positions,  absent  rotation,  etc. 

3.  Deflexion  attitudes — military  attitude,  forehead,  brow,  and  even  face  pres- 
entations and  their  seciuela?. 

4.  More  or  less  disproportion  between  the  size  of  the  passage  and  the  pas.senger, 
prolonged  lal)or,  and  operative  interference. 

Many  irregularities  in  the  labor  apart  from  the  above  have  l>een  observed. 
Some  of  these  are  indirectly  caused  by,  or  indirectly  influence,  the  mechanical 
factors  in  labor.  The  pains  are  ai)t  to  be  irregular,  intermittent,  and  inetTectual. 
Occasionally,  on  the  other  hand,  they  are  tunmltuous  and  (juickly  deliver  the  chiltl, 
j)erhaps  precipitately,  injuring  it  or  the  mother.  The  writer  had  one  case  of  com- 
l)lete  spontaneous  rupture  of  the  uterus  where  the  pregnancy  was  prolonged  anil 
labor  rapid.  This  is  the  exception.  Weak  jniins  are  the  rule.  It  is  possible  that 
a  fatty  degeneration  of  the  uterine  muscle  occurs  in  the.se  weeks  of  jirokjuged  i)reg- 
nancy  (Bossi).  This  invites  traumatic  rupture  or  produces  inertia,  necessitating  the 
use  of  forceps.  The  lack  of  strong  uterine  contractions  leaves  the  cervix  and 
vagina  without  the  softening  ami  succulence  neces.sary  for  the  .safe  dilatation,  and, 
therefore,  hu'erations  of  the  parts  are  fre(|Uent  and  all  operative  intervention  is 
rendered  Ial)orious.  The  same  inertia  is  carriinl  over  into  the  third  stage,  and 
postpartum  hemorrhage  caps  the  climax  to  the  succession  of  complications. 

While  these  accidents  are  by  no  means  the  rule  in  women  going  over  time,  they 
occur  so  often  that  the  cjue.stion  of  methodically  inducing  lal«)r  at  the  normal  «'nd 
of  gestation  deserves  grave  consideration. 

Prolonged  labor  is  a  peculiar  comlition.  Pains  l>egin,  the  cervix  becomes  ef- 
faced and  ojK'ns,  the  show  appears,  even  the  bag  of  waters  may  rupture,  but  deliwry 
does  not  occur.  I  have  seen  the  os  open  to  the  size  of  the  i>alm,  but  retract  and 
pregnancy  continue.  However,  intermittent  pains  (ledan*  that  the  woman  is  in 
labor.  In  a  ca.se  sent  to  tlu'  author  from  South  Dakota  the  woman  had  In^-n  in 
actutU  labor  for  eight  weeks  and  came  to  the  maternity  in  a  typhoidal  condition. 

473 


474  THE    PATHOLOGY    OF    PREGNANCY,    LABOR,    AND    THE    PUERPERIUM 

Dilatation  with  tlio  colpoiirynter,  cervical  incisions,  and  forceps  procured  a  43^ 
pound  emaciated  infant  which  survived.  The  process  was  repeated  in  a  subse- 
quent prepiancy.  Occasionally  labor  may  be  completely  interrupted  and  resumed 
at  a  later  i^eriod — perhaps  at  the  end  of  a  menstrual  cycle. 

The  causes  for  these  conditions  are  unkno^^^l — ])erhaps  some  disease  of  the 
uterine  muscle  or  of  the  nerves  of  the  uterus  should  be  invoked.  I  have  noticed 
that  my  cases  go  over  term  in  groups,  and  that  other  practitioners  are  having  the 
same  trouble  aljout  the  same  time.  This  fact  Bossi  also  mentions,  and  he  found 
that  the  condition  recurred  and  was  hereditary.  Old  primipara?,  women  who  have 
had  dysmenorrhea,  and  in  whom  the  pelvis  is  of  masculine  type,  seem  oftenest 
affected.  Fibroids  have  been  noted  in  several  cases.  A  peculiar  circumstance  in 
these  patients  is  that,  when  fever  begins,  which  is  not  unusual,  especially  if  the  bag 
of  waters  is  ruptured  and  the  vaginal  l^acteria  have  gained  access  to  the  uterus,  the 
pains  Ijegin  or  become  stronger,  and  deliver}^  is  completed  rapidly.  After  delivery 
the  t(Mnp(>rature  rapidly  becomes  normal. 

Treatment. — The  author  does  not  consider  it  good  practice  to  allow  gestation 
to  continue  long  after  its  natural  term  has  passed,  and,  likewise,  it  is  not  safe  to 
permit  a  protracted  labor  to  wear  out  the  woman's  strength,  as  it  is  ]:)ound  to  do  in 
time,  through  loss  of  sleep,  much  suffering,  and  anxiety.  If  labor  does  not  set  in 
on  the  day  which,  after  careful  computation,  has  been  set  for  it,  the  accoucheur 
makes  a  careful  examination  of  the  gravida.  Since  the  fingers  are  to  be  passed  into 
the  uterus,  the  preparations  of  the  patient  and  for  the  patient  should  be  identical 
with  those  of  actual  labor,  that  is,  shaving,  disinfection,  rubl^er  gloves,  etc.  The 
accoucheur  determines  the  size  of  the  infant,  using  cephalometry,  the  degree  of 
engagement  of  the  presenting  part,  and  the  state  of  the  cervix.  When  convinced 
that  the  end  of  normal  pregnancy  is  reached,  he  informs  the  woman  that  unless 
pains  begin  \\dthin  a  week  it  will  be  deemed  wise  to  inaugurate  labor.  This  is  best 
done  by  packing  the  lower  uterine  segment  and  the  cervix  with  gauze  (p.  1016). 
Pains  are  usually  easily  set  up,  because  the  irritability  of  the  uterus  has  been  de- 
veloped; indeed,  the  ease  with  which  uterine  contractions  are  elicited  indicates  the 
nearness  of  the  gestation  to  term.  Very  often  just  sweeping  the  fingers  around  the 
internal  os  and  slightly  separating  the  membranes  set  labor  in  progress.  Gill 
Wylie  recommended  a  dose  of  castor  oil  and  10  grains  of  quinin.  Pituitrin  has 
recently  been  used,  10  minims  hypodermically  every  four  hours.  The  injection 
of  the  blood-serum  of  new-born  infants  for  inducing  labor  is  now  being  experimented 
with.     The  serology  of  pregnancy  deserves  further  study. 

Missed  Labor. — This  is  a  term  applied  by  Oldham  to  the  retention  of  a  fetus, 
dead,  near  term,  in  the  uterus.  Missed  labor  often  occurs  in  cows  and  sheep. 
An  attempt  may  or  may  not  have  been  made  by  the  uterus  to  expel  its  contents. 
The  condition  is  similar  to  the  one  just  considered,  except  in  the  death  of  the  child, 
which  is  often  inexplicable,  and  is  the  same  as  ''missed  abortion"  (p.  435),  only  oc- 
curring later  in  pregnancy.  The  reason  for  the  failure  of  the  uterus  to  expel  the 
dead  product  of  conception  has  been  placed  in  a  rigid  cervix,  for  example,  cancer, 
scars,  hypertrophy,  a  diseased  uterus,  myomata,  muscular  degeneration,  cornual 
pregnancy,  peritonitis  "svith  adhesions,  and  nervous  disease.  After  the  fetus  dies 
it  mummifies  and  shrinks  up,  its  liciuor  is  absorbed,  and  the  uterus  applies  itself 
closely  to  the  body.  A  lithopedion  may  form,  as  in  extra-uterine  gestation,  or  in- 
fection, with  purulent  disintegration  and  extrusion  of  the  bones  of  the  skeleton 
through  the  cervix,  or  by  ulceration  through  neighboring  cavities — a  termination 
which  is  excessively  rare.  Usually  art  interferes  and  empties  the  uterus.  In 
Menzies'  case  the  dead  ovum  was  carried  to  the  seventeenth  month,  and  in  Hening's 
case,  eight  months  after  term. 

Symptoms. — One  finds  the  same  symptoms  here  as  in  missed  abortion  {q.  v.), 
but  exaggerated.     The  woman  complains  of  the  feeling  of  a  dead  and  heavy  mass 


PROLOXOED    PREGNANCY   AND    MISSED    LABOR  475 

in  the  belly,  and  n(jtos  the  absence  of  fetal  movements.  Pains  of  a  parturient 
character  occasional!}'  occur,  commonly  at  the  time  of  the  customary  menstrual 
periods,  and  it  is  at  such  tinu's  that  labor  often  sets  in. 

Exaniinati(jn  shows  a  closed  cervix,  anfl  a  thin-walle(l,  torpid  uterus,  of  hard 
consistence,  entirely  lacking  the  spongy  softness  characteristic  of  normal  preg- 
nancy. The  diagnosis  is  easy.  Since  the  question  of  pregnancy  is  .seldom  un<-er- 
tain,  all  that  is  needed  is  to  prove  that  the  .synunetric  tumor  is  the  uterus  and  that 
it  does  not  grow.  ( )ii  p.  2(i5  are  the  points  for  tlie  determination  of  the  life  or  death 
of  the  fetus. 

Treatment. — If  the  child  is  dead,  the  bag  of  waters  intact,  and  the  patient  not 
ill,  it  is  advised  to  wait  for  the  time  of  a  monthly  period  or  two  to  see  if  nature  will 
not  start  the  pains  and  empty  the  uterus.  In  the  interval  the  woman  must  bo 
enjoined  not  to  have  intercourse  nor  to  take  douches.  Some  authors  advise  the 
emptying  of  the  uterus  when  the  diagnosis  of  missed  lal)or  is  positive,  and  with  the.se 
I  agree,  because  the  uterine  contents  may  become  infected  while  waiting  and  this 
rentiers  an  otherwise  safe  operation  extremely  hazardous.  The  torpidity  of  the 
uterine  muscle  in  these  cases  is  sometimes  astonishing — one  may  u.se  all  sorts  of 
local  irritants — gauze,  colpeurynters,  etc. — for  days  without  evoking  pains.  It  is, 
therefore,  the  author's  practice  to  incise  the  cervix  or  do  vaginal  cesarean  .section 
if  the  uterus  proves  refractory  after  forty-eight  hours'  trial.  Since  the  fetus  is 
dead,  craniotomy  and  morccllation  are  indicateil  to  save  tlie  maternal  S(jft  parts 
from  injury.  If  the  mass  is  already  infected,  the  ca.se  is  treatetl  as  a  septic  al)ortion, 
with  tamjKjn  and  morcellation.  If  the  fetus  is  of  considerable  bulk,  laparotomy 
and  complete  extirpation  of  the  uterus  might  be  simpler  than  the  attemjjt  to  remove 
the  mass  from  below.  If  the  vaginal  route  seems  better,  one  should  not  try  to  re- 
move everything  at  one  sitting,  but  l)y  means  of  tamponing  and  morcellation  the 
cervix  is  kept  open,  drainage  provided,  and  the  fetus  and  the  secundines  gotten  rid 
of  safel\'  and  witliout  injury  to  the  uterus. 

Graviditas  Exochorialis. — Among  the  rare  conditions  met  with  is  the  di'veloi>- 
ment  of  the  fetus  in  the  uterus,  but  outside  of  the  amniotic  cavity.  In  such  ca.ses 
the  membranes  shrink  up,  the  lifjuor  amnii  continually  eseajies,  sometimes  in  large 
amounts,  and  the  fetus  may  show  the  results  of  oligohydranmion — contractures, 
clul)-feet  and  arms,  decubitus,  etc.  The  differential  diagnosis  must  be  made  from 
hydrorrhoca  graviilarum  {q.  v.).     Abortion  is  fretpient.

CHAPTER  XXXVII 

DISEASES  ACCIDENTAL  TO  PREGNANCY 

A  PREGNANT  womaii  is  not  immune  to  any  disease  which  may  affect  her  in  the 
non-pregnant  state,  and,  contrary  to  the  old  notion,  she  is  more  susceptible  to  some. 
Pregnancy  in  general  aggravates  the  diseases  which  occur,  and  in  turn  the  gesta- 
tion is  endangered  by  them.  Abortion  or  premature  labor  occurs  with  varying 
frequenc}'  in  all  the  infectious  chseases,  and  also  often  complicates  the  course  of 
constitutional,  circulatory,  respiratory,  alimentary,  and  kidney  affections.  It  is 
ob^^ously  impossible,  in  a  book  of  this  size,  thoroughly  to  consider  all  the  maladies 
from  which  a  pregnant  woman  might  suffer.  Only  the  salient  points  of  large  groups, 
and  especially  important  features  of  individual  diseases,  will  receive  mention. 
The  reciprocal  influences  of  pregnancy  upon  the  disease  and  of  the  disease  upon 
pregnancy  will  be  studied  in  turn. 

THE  ACUTE  INFECTIOUS  DISEASES 

Typhoid,  typhus,  measles,  scarlatina,  variola,  erysipelas,  diphtheria,  cholera, 
malaria,  influenza,  pneumonia — all  occur  in  pregnancy,  and  most  of  them  have  a 
very  deleterious  effect  on  both  mother  and  fetus.  The  action  of  these  diseases  is 
twofold:  first,  they  endanger  the  woman  through  hj^^erpyrexia,  increased  toxemia, 
the  accompanying  nephritis,  and  through  the  tendency  to  become  hemorrhagic. 
Profuse  menorrhagias  are  often  noted,  some  of  which  may  be  early  abortions,  and 
a  differential  diagnosis  may  have  to  be  made  from  several  conditions.  For  ex- 
ample, a  young  woman  was  sent  to  the  author  with  a  diagnosis  of  septic  abortion 
with  profuse  hemorrhage.  She  was  in  the  first  week  of  typhoid,  with  epistaxis 
uterina,  and  was  a  ''virgo  intacta." 

Women  who  have  had  an  exhaustive  siege  of  disease  are  in  poor  condition  to 
withstand  the  pain,  shock,  and  hemorrhage  of  abortion  or  labor,  and  collapse  may 
come  on  in  the  third  stage.  This  is  especially  true  when  the  lungs  or  heart  are  much 
involved.  Finally,  some  of  the  above-mentioned  diseases  lead  directly  to  puerperal 
sepsis,  either  by  blood  or  regional  transmission  of  the  bacteria,  or  by  so  reducing  the 
immunities  of  the  patient  that  infection  easily  gains  foothold.  Examples  of  these 
are  variola  (infection  from  the  pustules),  typhoid  (the  streptococci  from  Peyer's 
patches,  and  even  the  typhoid  bacilli  themselves),  influenza  (direct),  erysipelas 
(direct),  scarlatina  (from  the  throat),  pneumonia  (direct),  diphtheria  (direct),  etc. 

Second,  these  diseases  interrupt  pregnancy,  which  is  due  to  a  not  infrequently 
accompanying  hemorrhagic  endometritis  and  to  the  death  of  the  fetus.  Fetal 
death  is  brought  about  in  various  ways : 

(a)  The  fetus  may  die  from  insolation.  Nornially,  the  temperature  of  the  fetus  is  one- 
half  a  degree  higher  than  that  of  the  mother,  and  since  it  has  its  own  heat-regulating  system, 
it  can  take  care  of  the  ordinary  changes,  but  when  the  mother  is  hyperpyretic,  the  child  cannot 
do  so  because  it  has  not  the  means  to  discharge  heat,  as  by  evaporation,  for  example.  High 
temperature,  especially  a  sudden  rise,  is,  therefore,  less  well  borne.  Runge  and  Dore  showed  that 
a  gradual  rise  to  104°  F.  is  fairly  well  borne,  and  unless  continued  thus  for  a  long  period,  is  usually 
survived  by  the  infant.  The  movements  and  the  heart -tones  are  at  first  increas(>d,  later  slowed, 
and  death  occurs.  Rabbits  will  stand  a  very  gradual  rise  to  109°  F.,  but  if  it  is  sudden,  it  is 
always  fatal.  Krummaker  reported  a  case  of  hysteric  fever  with  sudden  rises  of  109.4°  F.  at 
intervals  for  seven  days  without  effect  on  the  child. 

(b)  Pregnancy  is  interrupted  by  the  hot  blood  circulating  through  the  uterus.  This  is 
not  improbable,  because  heat  applied  to  the  abdomen  and  by  hot  douches  causes  the  uterus  to 
contract,  and  clinical  experience  in  delayed  labors  shows  that  when  the  temperature  rises,  as 
from  sepsis,  the  pains  grow  stronger.

the  toxins  which  it  receives  from  the  maternal  circulation.  The  villus-wall  ofTers  no  hindrance 
to  the  passage  of  the  toxins,  which,  liki-  other  i)oisons,  strychnin  and  [xitassium  io-iid,  are  known 
to  p)  throufih,  as  also  do  antitoxins,  for  example,  dijihtlieria.  'J'he  villus  is  no  barrier  t(j  the  pa.ss;ine 
of  the  bacteria — they  either  pass  through  directly  or  after  destroyinu  the  wall,  and  lesionn  of  the 
latter  are  not  h:ird  to  'find.  The.se  infections  have  been  demonstratfHJ  in  the  fetus:  variola. 
mea.->les,  .scarlatina,  typhoid  (the  author  in  ISyi),  diolera,  jjueumonia,  bubonic  jjIaKiie,  erysijx-lasi 
I)us  infect icms,  anthrax,  tuberculosis,  .syphilis,  febris  recurrens,  malaria.  It  is  remarkable  that 
in  some  of  the  di.sea.ses  the  child  is  not  at  all  affect (h1,  and  the  author  has  had  c;is<-s  where  tlie  child 
alone  was  ill,  the  mother  remaining  free.     Others  have  noted  such  an  <j<-currence  in  srnulliK>x. 

Typhoid. — It  i.s  said  tliat  typhoid  is  rare  in  prcRiiancy.  Frcund  found  42  casps 
in  '.Vll'l  t\  j)iioiils,  ^vhit•h  i.s  not  cxcc.s.sivi'ly  rare  when  all  the  facts  are  eon.sjdered. 
The  Eherth  bacillu.s  and  the  Widal  reaction  have  been  found  in  the  fetal  l)lood, 
especially  in  the  latter  months  of  gestation.  Pregnancy  is  int(Truj)ted  in  two-thirds 
of  the  cases,  especially  in  the  early  months.  Children  of  the  later  months  almost 
always  die  after  birth.  Hemorrliast'  is  usually  not  jirofu.se,  but  the  accouclieur  is 
warned  to  prevent  all  bleeding  because  of  the  exhaustion  of  the  patient.  The  .soft 
parts  are  very  ea.sily  torn,  but  bleed  little.  Union  was  good  in  the  author's  three 
ca.ses.  The  mortality  is  higher  tlian  in  uncomplicated  ty])h(jid.  In  the  puerjx'rimn 
the  ditVerential  tliagnosis  is  most  imi)ortant,  since  the  feviT  is  usually  astTilwd  to 
l)uerjx'ral  sepsis.  The  gradual  ri.se  of  fever,  the  absence  of  chills,  the  slow  pulse, 
the  tendency  to  apathy,  not  excitement,  the  early  splenic  tumor,  the  stool,  the  ro.se- 
ola,  and  the  negative  findings  on  the  genitalia  usually  enable  the  lirojjer  course  to  be 
taken,  ])ut  one  should  always  try  the  Widal  reaction,  and,  if  necessary,  make  a 
culture  from  the  blood.  A  typhoiil  puerperal  infection  is  not  impossible,  and  ty- 
phoid may  be  combined  with  putrefactive  and  purulent  infections. 

Variola. — In  the  majority  of  ca.ses  of  smallpox  abortion  or  premature  labor 
occurs,  anil  the  child  almost  always  dies.  It  may  l)e  i)orn  j)ock-marked.  as  was  the 
accoucheur  Mauriceau,  or  in  the  (Tuptive  stage.  Confluent  and  liemorrhagic 
variola  are  more  connnon  in  gravitUe,  ami  the  mortality  is,  therefore,  much  higluT 
(Vinay,  30  per  cent.).  Sepsis  may  arise  from  the  pustules,  and  after  recovery  from 
the  smallpox  a  recrudescence  of  the  fever  may  occur  from  the  r(\soriition  of  toxic 
material  from  the  fetus,  which  disai^jiears  when  the  utcTUs  is  emjitied.  Hemorrhage 
during  lal)or  is  greater.  \'aginal  examination  and  intra-uterine  manij>idations  are 
to  be  avoided,  as  far  as  possible,  becau.se  of  the  danger  of  introilucing  infection. 

Vaccination  during  the  disease  not  always  protects  the  child,  which  may  be 
infected  during  delivery  or  afterward  (i.solation  for  the  healthy  child).  \'accination 
of  the  child  should  be  done  inunediately  on  delivery,  but  it  usually  do(\s  not  i>rotect. 
Women  who  have  been  vaccinated  or  who  have  had  variola  during  pregnancy  give 
i)irth  to  children  which  later  are  immune  to  vaccination  and  smallix)x  (Kollock  and 
Sawyer).  On  the  other  hand,  vaccination  of  the  mother  sometimes  has  no  protec- 
tive influence  on  tlu'  child.  Franklin  rei>orts  a  case  wIktc  the  father  had  smalljxjx; 
the  mothtT.  vacc-inated,  remained  well,  but  the  child  was  born  dead  of  smallpox, 
which  shows  that  the  child  received  the  contagion  through  its  healthy  mother. 

Scarlatina. — Pregnant  women  seldom  get  real  scarlatina  (Hallantyne).  but 
erythemnta  which  resemble  it,  due  to  sepsis,  are  not  uncommon,  e.sixM'ially  in  the 
l)uerperiinn.  Tiie  relations  of  scarlet  fever  to  sepsis  are  not  y»'t  decided  uixm.  and 
will  not  be  until  the  exciting  cau.se  of  scarlatina  is  known,  btit  i)r<)bably  the  strepto- 
coccus has  sometliing  to  do  with  both  di.seases  when  a  connection  U'twe<Mi  the  two 
is  suspected.  The  author  knows  of  many  in.stances  of  labor  occurring  in  the  same 
room  with  children  sutTering  from  scarlet  fev(T  and  has  .s«'en  no  trouble  ari.se  there- 
from.    Of  course,  jjrecautions  wc  re  taken.  l)Ut  these  could  not  always  l)o  complete, 


478      THE  PATHOLOGY  OF  PREGNANCY,  LABOR,  AND  THE  PUERPERIUM 

and  often  were  largelj'  neglected.  The  mortality  of  scarlatina  in  the  puerperium  is 
given  as  from  5  to  52  per  cent.,  and  the  frequency  of  puerperal  ulcers,  parametritis, 
and  puerperal  infection  in  general  as  complications  is  emphasized  (Tornery). 

In  the  puerperium,  unless  an  epidemic  of  scarlet  fever  is  raging,  it  is  best  to 
consider  the  scarlatiniform  cruj^tion  as  due  to  infection,  unless  the  other  character- 
istics of  the  case  stamp  it  cUstinctly  as  scarlet  fever. 

Measles. — Fellner  collected  30  cases  from  the  literature.  Measles  is  a  serious 
complication  of  pregnancy,  as  it  generally  is  in  adults.  Gestation  was  interrupted 
in  55  per  cent.;  the  general  mortality  was  15  per  cent.;  during  the  puerperium  two 
of  three  women  died.  Sepsis  explains  the  high  mortality.  The  children  are  usually 
affected  by  the  disease  and  show  the  eruption,  as  the  one  of  Clarus  did  when  re- 
moved by  cesarean  section  from  the  dead  body  of  its  mother.  In  the  service  of  the 
Cliicago  L}ang-in  Hospital  Dispensary  many  of  the  puerperse  are  exposed  to  this 
contagion  from  their  sick  children,  but  in  no  case  has  measles  developed,  which 
shows  that  even  the  imperfect  isolation  possible  in  the  homes  of  the  poor  will  suffice 
to  protect.  In  one  of  ni}^  cases  the  child  developed  tji^ical  measles  on  the  tenth 
day,  the  mother  being  free. 

Cholera. — In  the  Hamburg  epidemic  of  1892,  57  per  cent,  of  pregnant  women 
affected  by  cholera  asiatica  died  (Schiitz).  Aljortion  was  very  frequent  because  of 
hemorrhagic  endometritis.  The  disease  usualh'  is  not,  but  may  be,  transmitted  to 
the  child. 

Erysipelas. — When  this  disease  attacks  any  other  portion  of  the  body  than  the 
genitalia,  it  seems  to  be  less  dangerous,  but  many  records  are  at  hand  to  show  that 
puerperal  infection  may  result  in  such  cases.  The  author  delivered  a  woman  suffer- 
ing from  facial  erN'sipelas;  shortly  after  birth  the  vulva  became  red,  and  she  died 
under  the  picture  of  acute  sepsis.  At  the  autopsy,  from  the  very  little  clear  peri- 
toneal fluid,  a  pure  culture  of  Streptococcus  pyogenes  was  recovered.  The  identity 
of  the  Streptococcus  erysipelatis  of  Fehleisen  with  the  streptococcus  of  pus  is  under 
chscussion.  (See  Puerperal  Sepsis.)  Pregnane}'  is  not  often  interrupted  by  ery- 
sipelas, and  frequently  the  children  are  delivered  alive,  but  they  may  have  the  dis- 
ease.  The  mortality  is  increased.    Late  literature  on  the  subject  is  scarce  (Lebedeff) . 

Sepsis. — Under  puerperal  infections  the  usual  forms  of  sepsis  will  be  considered 
at  length.  Here  might  briefly  be  mentioned  infections  of  distant  portions  of  the 
bod}^,  for  example,  mastoiditis,  frontal  and  other  sinusitis,  tonsillitis,  abscesses, 
cellulitis,  anthrax,  and  tetanus.  These  diseases  are  usually  aggravated  by  preg- 
nancy, and  their  bacteria  may  be  transmitted  by  way  of  the  blood-stream  to  the 
uterus  and  the  fetus.  It  is  possible,  too,  that  direct  transference  of  the  virus  may  be 
effected  by  the  woman  herself  with  her  fingers.  A  local  infection  of  the  uterus  and 
fetus  may  occur  at  any  period  of  gestation  and  cause  abortion.  The  author  is 
convinced  that  coitus  in  the  latter  weeks  often  causes  labor  to  set  in,  and  may  be 
followed  by  serious  puerperal  infection. 

Malaria. — ]\Iilcl  cases  of  malaria  exert  little  influence  on  gestation.  Severe 
cases  may  interrupt  pregnane}'  through  fever  or  cachexia.  Labor  may  change  the 
type  from  tertian  to  cjuoticUan.  Williams  could  not  find  the  plasmodium  in  15  in- 
fants when  it  had  been  demonstrated  in  their  mothers,  yet  Bodenhauser  reports  a 
case  of  such  transmission,  and  fetuses  have  been  delivered  with  enlarged  spleen  and 
pigmentation.  During  labor  an  attack  may  occur.  Uterine  action  is  torpid. 
Hemorrhages  have  been  noted  postpartum.  The  author  had  a  case  of  hem()])]iilia 
which  seemed  to  be  malarial  in  origin.  Lardier  speaks  of  hemorrhage  in  labor,  and 
Legeois  and  Barker  of  bleeding  later  in  the  puerperium.  Postpartum  malaria 
seems  to  be  a  little  more  serious  than  usual,  l)ut  its  chief  interest  is  in  the  diagnosis. 
Practitioners  in  malarious  regions  find  many  times  that  an  outbreak  of  malaria 
occurs  in  the  pu(»rperium  in  a  manner  similar  to  that  of  a  fresh  attack  after  an 
operation.  In  such  cases  puerperal  infection  is  to  be  excluded  and  the  plasmodium 
demonstrated.     Quinin  is  to  be  administered  whenever  indicated  (Fry,  Deale). 


DISEASES   ACCIDENTAL   TO    PREGNANCY  479 

Influenza. — Owinf;  to  the  variations  in  the  severity  (jf  influenzal  epidemics  and 
pandemics,  and  the  difficulty  of  difTerentiatiuK  the  milder  cases  from  ordinary 
catarrhal  affections, the  reports  of  oi)servers  difTer  as  totheefTect  of  la  ^rippeon  preg- 
nancy. The  Kii'^tro-iiitestinal  f(jrm  of  la  Krij)pe  in  pref;;naiicy  is  ncjt  always  att<'nded 
hy  hyperpyrexia.  The  excessive  vomiting  may  raise  the  suspicion  of  hyperemesis 
{^raviilarum.  In  the  nervous  forms  eclampsia  should  he  thought  of,  though  these 
varieties  are  vcryunusual  ingravid  women.  The  respiratory  grip  is  themost  serious 
in  pregnancy,  and  if  attended  with  marked  toxemia,  may  lead  to  its  interruption, 
usually  through  uterine  hemorrhage  and  endometritis.  The  severe  cough,  dyspnea, 
and  insonmia  are  exhausting.  During  labor  the  uterus  is  tender  and  inactive,  and 
operative  interference  oftener  indicated.  In  the  puerperium  influenza  is  not  rarely 
the  cau.se  of  fever,  and  it  is  frequently  difficult  to  decide  if  there  is  not,  in  addition, 
a  i)ucri)eral  infection.  Streptococcic  invasion  of  the  uterus  after  la  grippe  is  not 
unknown.  Stoltz  found  decomposition  of  the  lochia  in  .jO  i)er  cent.  Suijinvolution 
is  connnon,  and  lactation  retarded.  Pneumonia,  pleurisy,  meningitis,  and  sinus 
suppurations  occur  with  double  the  frequency  of  the  normal  state.  Rarely  is  the 
fetus  affected,  excepting  in  tho.se  epidemics  attended  by  high  mortality  and  a  large 
percentage  of  abortions.  The  treatment  is  along  general  lines.  Labor  is  not  to  be 
inducet-l  unless  cyanosis,  dysjmea,  or  threatening  resjjiratory  or  cardiac  failure  indi- 
cate it.  The  bag  of  waters  is  to  be  ruptured,  a  colpeurynter  to  be  applied,  and  as 
soon  as  the  cervix  will  permit  it,  extraction  is  to  be  efTected.  The  jiatient  slujuld  not 
l)e  allowed  to  lal)or  long  nor  to  bear  down  much — both  are  exhausting.  Prepara- 
tions similar  to  those  for  treating  heart  disease  are  to  be  made  (Moller). 

Pneumonia. — Pneumonia  must  be  consideretl  one  of  the  specific  infections, 
with  localization  in  the  lungs,  and  it  acts  in  many  ways  like  most  of  the  diseases 
described  in  this  chapter.  Pregnancy  is  interrupted  in  more  than  half  of  the  ca.ses, 
especially  if  it  already  is  in  the  latter  months.  Cyanosis  and  dyspnea  are  more 
marked,  especially  in  the  last  few  weeks,  when  the  excursions  of  the  diaphragm  are 
restricted  by  the  large  uterus,  and  particularly  if  the  al)domen  is  tymjianitic. 
Cardiac  collapse  is  earlier  and  more  frequent;  indeed,  pregnancy  and  pneumonia 
are  a  dangerous  combination.  Vinay  collected  cases  which  showetl  a  maternal 
mortality  of  OS  j)er  cent,  when  ])regnancy  was  interrupted,  and  of  1.")  jn-r  cent,  when 
it  went  on  undisturbed.  Pneumonia  may  affect  the  fetus,  and  its  chances  generally 
are  not  good,  though  Fellner  quotes  19  ca.ses  of  Schauta's  clinic,  with  only  1  death. 
One  should  not  induce  labor  except  for  threatening  symptoms  of  cardiac  or  respira- 
tory collapse,  the  same  rules  guiding  here  as  were  mentioned  under  Influenza.  The 
rapid  nu'thods  of  emptying  the  uterus  are  to  be  selected. 

Pneumonia  in  the  ])ueri)erium  may  be  due  to  the  pneumococcus,  may  result 
from  the  anesthetic  (bronchopneumonia),  or  be  hypostatic  or  enibolic.  The  la.^t  two 
forms  appear  in  septic  cases — the  one  from  cachexia  and  the  other  from  embolism 
from  infected  pelvic  veins  {q.  v.).  Other  manifestations  of  jmeumococcus  invasion 
are:  Pleurisy,  pericarditis,  endocarditis,  meningitis,  otitis  media,  sinus  infections, 
endometritis,  and  ophthalmia  neonatorum,  besitles  other  fetal  infections. 

For  further  information  on  all  these  subjects  see  Friinkl-Hochwart  and  v.

CHAPTER  XXXVIII 
THE  CHRONIC  INFECTIOUS  DISEASES 

Pulmonary  tuberculosis  has  a  marked  influence  on  the  woman  during  the  per- 
formance of  the  reprotUiotive  function.  In  the  advanced  cases  menstruation  is 
usually  suppressed,  which  may  be  looked  upon  as  the  conservative  effort  of  nature, 
as  the  result  of  extreme  cachexia  with  atrophy  of  the  ovaries,  or  local  tubercular 
disease  of  the  genitaha.  In  beginning  tuberculosis  amenorrhea  or  scanty  menses 
may  be  noted,  and  since  the  girl  may  be  chlorotic,  a  difficult  diagnostic  problem  may 
present  itself — chlorosis  or  tuberculosis,  or  both.  Every  chlorotic  girl's  lungs  should 
be  carefully  examined.     A  leukorrhea  may  substitute  the  menses  in  such  cases. 

Sterility,  fortunately,  is  not  rare  in  tubercular  men  and  women,  but  only  in  ad- 
vanced cachectic  individuals.  Pregnancy  does  not  confer  immunity  on  women 
against  the  disease,  as  was  once  held;  on  the  contrary,  conception  may  arouse  a 
latent  affection,  or  even  develop  it  in  an  individual  who  only  displayed  a  tendency 
to  become  tubercular.  An  existing  pulmonary  disease  is  apparently  benefited  by 
pregnancy,  the  gravida  developing  red  cheeks,  a  lively  expression  of  countenance, 
\v\th.  clear  eyes,  and  even  rarely  putting  on  fat,  but,  withal,  the  consolidation  is 
making  rapid  progress,  and  after  delivery  caseous  degeneration  will  occur  more 
rapidly  than  l:)efore.  Ordinarily,  the  disease  makes  deep  inroads  during  gestation, 
and  the  author  has  noticed  this  occur  especially  if  the  woman  also  suffers  from  hy- 
peremesis.  If  a  dormant  tuberculosis  awakens  in  pregnancy  or  a  new  infection 
occurs,  the  course  of  the  disease  is  apt  to  be  more  rapid,  being  usually  of  the  more 
florid  t}T3e,  the  tendency  to  fever  greater,  and  emaciation  more  marked.  Hemop- 
tysis occurs  in  50  per  cent,  of  the  cases.  Tuljcrculosis  of  the  larynx,  heart  disease, 
and  nephritis  aggravate  the  pulmonary  condition  decidedly.  The  chronic  ulcera- 
tive varieties  of  tuberculosis  do  not  usually  produce  such  marked  symptoms  during 
pregnancy,  the  author  having  seen  such  women  have  children  repeated^,  without 
greater  aggravation  of  the  disease  than  one  would  expect  under  other  circum- 
stances. 

The  puerperium  also  has  a  deleterious  influence  on  the  disease.  Owing  to  the 
changes  in  the  lungs  and  heart  and  the  drain  on  the  system  caused  by  pregnancy  and 
labor,  especially  if  there  has  been  much  hemorrhage,  the  caseous  deposits  soften 
and  rapidly  break  down,  hectic  develops,  and  the  course  of  the  affection  goes  down- 
ward fast.  If  the  patient  has  tuberculous  laryngitis  in  addition,  she  rarely  survives 
the  puerperium  (Kiittner,  90  per  cent,  mortality). 

Pregnancy  is  rarely  interrupted,  and  then  the  infection  is  usually  very  florid, 
and  resembles  a  pneumonia  more  than  a  typical  tuljcrculosis. 

During  labor  the  degree  of  involvement  of  the  lungs  will  determine  how  much 
trouble  will  be  met.  Mild  cases  go  through  it  without  causing  anxiety.  Advanced 
cases  are  harassed  by  dyspnea,  cough,  occasionally  hemoptysis,  and  threatened  by 
cardiac  collapse,  oedema  pulmonum,  pneumothorax,  and,  rarely,  a  spread  of  the 
infection  into  general  miliary  tuljcrculosis.  Labor  is  slower,  and  the  second  stage 
is  prolonged  and  critical.  During  the  puerperium  fever  is  common;  a  l^ronchitis 
is  often  added  to  the  other  troubles,  but,  in  the  author's  experience,  sepsis  has  not 
been  more  frequent.     The  differential  diagnosis  from  sepsis  is  easy. 

Tuberculosis  has  decided  immediate  and  remote  influence  on  the  child.  Birch- 
Hirschfeld  (1891)  first  demonstrated  tuberculosis  in  the  fetus,  and  Schmorl  showed 

480 


THE    CHRONIC    INFECTIOUS    DISEASES  481 

it  in  tiic  ijlucontii  in  .')()  por  cent,  of  the  cases,  though  Hardy,  in  1834,  mentions  it. 
Bar  and  Kcnon  found  tulx-rclc  bacilH  in  the  blood  of  the  umhiHcal  cord  in  2  of  5 
cases.  Placental  tuberculous  foci  usually  precede  fetal  disease,  but  without  d(jubt 
the  bacilli^may  pass  directly  to  the  fetus  through  the  walls  of  tin'  villi.  Cong<'nital 
tuberculosis  was  held  impossible  for  years  and  by  many,  but  it  (jc<-urs.  and  probably 
more  fre([uently  than  is  generally  known.  Friedman  injected  weak  suspensi(jns  of 
tuljcrcle  bacilli  into  the  vaginas  of  recently  imj)regnated  guinea-i)igs  and  pnjduced 
fetal  tul)erculosis.  By  men,  through  dirty  habits,  or  from  genital  tubercular  foci, 
the  bacilli  could  be  introduced  with  the  semen.  Baumgarten  held  that  the  dis<'ase 
was  inherited,  the  germs  developing  at  a  later  period,  l)ut  i)robal)ly  a  weakness  of 
the  constitution,  a  tendency  to  tiie  malady,  is  inherited,  and  the  environment  of  the 
child  aiul  the  numerous  opportunities  for  infection  are  the  exciting  cau.ses. 

The  children  of  tubercular  women  may  be  large  and  robust,  especially  if  the 
disease  is  of  the  chronic  type.  Puny  children  also  are  born,  and  many  die  in  the 
first  weeks  or  months.  The  autiior  knew  a  family  in  which  six  children  died  con- 
secutively of  tubercular  meningitis.  It  is  jjossible  that  the  child  becomes  tuber- 
culous through  the  mother's  milk. 

Treatment. — Women  with  tuberculosis  should  not  marry — first,  because  this 
aggravates  their  own  disease;  second,  they  may  infect  the  luisband;  and,  third, 
they  ])roj)agate  tuberculous  children.     The  same  is  to  be  said  of  the  husband. 

If  the  tuberculosis  is  latent,  or  if  the  candidates  possess  only  the  hereditary 
taint,  the  question  is  more  difficult,  but  it  is  only  exceptionally  that  the  doctor's 
advice  is  asked.  Knowing  the  tendency  for  a  latent  tuberculosis  to  break  out  in 
pregnancy,  marriage  is  to  be  forbidden.  If  the  woman  marries,  she  should  avoid 
conception.  Finally,  if  she  conceives,  she  should  not  nurse  the  baby.  The  disease 
makes  great  progress  during  the  puerperium,  especially  if  the  woman  nurses.  The 
tuberculin  tests  may  be  made  on  gravida?. 

During  pregnancy  the  recognized  medical  treatment  is  carried  out.  Should 
the  ])regnancy  be  interrupted  because  the  mother  has  pulmonary  tuberculosis? 
Opinions  differ,  three  positions  V)eing  held:  one,  that  pregnancy  be  always  inter- 
rupted as  a  curative  measure;  another,  that  it  be  never  interrupted,  and  the  third, 
that  the  cases  be  individually  treated  and  the  gestation  brought  to  an  end  only 
when  certain  symptoms  indicate  it.  I  am  inclined  to  a  more  active  treatment.  If 
tuberculosis  of  the  lungs  is  manifest  in  early  pregnancy;  if  there  are  fever,  wa.^ting, 
hemoptysis,  and  advancing  consolidation, — that  is,  the  process  seems  to  Ix?  florid, — 
abortion  should  l)e  induced  without  delay.  Trembley,  of  Saranac  Lake,  induces 
abortion  in  the  early  months  in  all  cases,  ami  says  that  the  mortality  and  p«Tcentage 
of  relajises  are  practically  nil  when  abortit)n  is  induced  before  the  end  of  the  third 
month.  If  the  i)rocess  seems  very  chronic,  esjK'cially  if  the  patient  comes  in  the 
second  half  of  pregnancy,  it  is  ju.stifiable  to  wait  and  watch  do.sely.  If  the  preg- 
nancy is  near  the  period  of  viability,  one  may  tide  the  woman  over  a  few  weeks  for 
the  sake  of  the  child,  or  even  allow  her  to  go  to  term,  dej)ending  on  her  condition. 
Urgent  sym])toms  of  cardiac  nature,  persistent  hemoptysis,  and  ilys|)nea  may  re- 
quire the  emjitying  of  the  uterus.  C"omi)licating  nej>hritis,  heart  di.xea.-^*'.  and  con- 
tracted pelvis,  which  is  said  to  be  more  frequent  in  the  tuberculous,  will  give  earlier 
indication  for  interfiTcnce.  Tul)ercuk)sis  with  hNi^^emesis  makes  the  indication  for 
immediate  abortion. 

Laryngeal  tuberculosis  in  the  early  months  is  a  positive  indication  f(»r  abortion; 
in  the  later  months  one  may  temporize,  unless  oi)structed  breathing  forces  the 
hand.  Be  ready  to  do  tracheotomy.  In  tuberculous  cases  anesthetics  are  used 
only  when  very  nec(>ssary.  Abortion  may  be  done  in  two  sittings:  the  first, 
for  packing  the  uterine  cavity  with  gauze.  aft<T  opening  the  ovum,  and  the  sec- 
ontl  on  the  day  following,  for  removing  the  contents  (»f  the  uterus,  unless  these 
have  come  away  spontaneously.  Premature  labor  is  performed  by  ruot wring  the

membranes  and  metreurj'sis,  unless  great  urgency  necessitates  more  rapid  operating, 
when  vaginal  cesarean  section  may  be  done.  Bumm  recommends  extirpation  of  the 
uterus  at  this  opportunity,  and  others  tying  off  the  tubes  to  procure  sterility.  Dur- 
ing labor  the  general  course  is  expectancy,  but  armed  for  all  emergencies.  The 
heart  has  been  poisoned  so  long,  a  subcyanotic  condition  of  the  blood  has  existed  so 
long,  that  the  cardiac  muscle  is  likel}'  to  be  diseased;  therefore  to  it  we  give  our 
main  attention.  As  soon  as  dilatation  is  complete  and  the  head  on  the  perineum, 
forceps  are  to  be  applied,  unless  the  woman's  condition  is  so  good  that  interference  is 
unnecessary.  The  hemorrhage  of  the  third  stage  is  to  be  limited.  The  author  has 
used  ether  in  these  cases  with  no  worse  effects  than  follow  chloroform.  In  the 
puerperium  one  should  keep  up  the  heart  A^th  caffein,  strychnin,  and  digitalis, 
but  especially  good  are  fresh  air  and  full  diet.  Lactation  is  forbidden,  and  the  child 
should  be  removed  from  the  environment  in  which  it  was  born  unless  the  parents 
are  intelligent  enough  to  carry  out  the  necessary  precautions  for  its  safety.  The 
woman  should  be  instructed  how  to  avoid  pregnancy  in  the  future.  Something 
must  be  done  until  the  woman  is  cured  of  her  tuberculosis,  so  that  she  may  safely 
go  through  a  confinement,  because  every  accoucheur  recoils  with  horror  from  the 
task  of  repeatedly  doing  abortions  on  these  tuberculous  women.     (See  Bacon.) 

Syphilis. — Obstetricians  should  constantly  be  on  the  alert  for  this  protean 
disease.  Its  baneful  action  is  often  discovered  when  least  expected,  and  it  spreads 
its  blight  on  all  three  individuals  concerned  in  the  propagation  of  the  species,  even 
being  transmitted  to  the  second  generation.  Ricord  says  that  in  Paris  one  in  eight 
is  s\'philitic,  and  while  in  America  the  conditions  are  better,  the  disease  is  not  rare, 
and  in  its  lesser  manifestations  quite  common,  though  often  not  diagnosed.  First 
maternal  s^-philis,  then  paternal,  will  be  considered. 

Effects  of  Pregnancy  on  Syphilis. — If  a  woman  acquires  lues  at  the  same  time 
that  she  is  impregnated,  or  if  she  conceives  while  still  in  the  florid  stage,  the  disease 
assumes  graver  forms  than  in  the  non-pregnant.  The  chancre  is  larger  than  usual, 
hypertrophies,  is  more  moist,  vascular,  and  soft,  and  shows  a  tendency  to  ulcerate 
or  become  phagedenic.  It  lasts  longer,  and  may  often  be  found  even  after  twelve 
weeks.  Secondaries  develop  sooner  and  are  more  marked,  especially  those  on  the 
genitalia,  because  of  the  natural  succulence  of  the  parts.  The  exanthem  is  very 
wide-spread;  the  papules  are  likely  to  be  large,  and  pustular  forms  are  commoner. 
More  enlargement  of  the  glands  is  observed,  and  they  tend  more  to  suppuration. 
Eroded  papules  are  very  numerous  on  the  vulva  (Fournier) ;  "they  develop  with  a 
singular  exuberance,  take  on  quickly  a  granulating  condition,  hypertrophy,  and 
often  constitute  veritable  tumors,  which  invade  and  deform  the  entire  vulva. 
Further,  they  are  always  more  rebellious  to  treatment,  being  reabsorbed  slowly  and 
with  difficulty.  The  ulcerating  s;^T)hilids  are  very  frequent  in  pregnant  women,  are 
livid,  purple,  and  excavated,  which  condition  is  increased  by  the  general  tumidity 
of  the  parts.     They  persist  longer  and  have  a  tendency  to  become  phagedenic." 

Pregnancy  aggravates  the  general  symptoms  of  sj-philis,  the  anemia  is  more 
profound,  fever  more  common  and  a  little  higher,  digestive  troubles  are  marked, 
neuralgias,  headache,  insomnia,  and  bone  pains  all  exaggerated.  Neuralgias  be- 
ginning shortly  after  marriage  may  serve  to  draw  attention  to  the  infection.  Ter- 
tiary syphilis  is  less  affected  by  the  advent  of  pregnancy,  though  sometimes  it  may 
awaken  the  disease  which  was  thought  to  have  been  cured. 

Effects  of  Maternal  Syphilis  on  the  Pregnancy. — Luetic  women  are  often  sterile, 
perhaps  because  the  ovarian  function  is  suspendcnl  in  a  manner  similar  to  that  of  the 
testicle  in  syphilitic  men.  There  is  a  sj'philitic  endometritis  which  may  explain 
some  cases.  The  actual  effects  on  the  pregnancy  may  vary  with  the  age  of  the 
sj-philis  and  the  success  of  the  treatment,  because  if  the  patient  has  been  success- 
fully treated,  she  may  bear  healthy  children. 

If  the  syphilis  is  more  recent,  the  fetus  dies  and  abortion  occurs.     The  subse- 


THE    CHHONIC    INFECTIOUS    DISEASES  483 

quent  pregnancies  terminate  tiie  same  way,  l)Ut  each  one  later,  until  a  living  but 
sy])hiliti('  fetus  is  l)orn.  and  finally  a  living,  api)arfntly  well,  child  at  term.  This 
may  develop  syphilis  within  two  months  (lues  ccjugenita  tarda)  or  after  years  (lues 
hereditaria  tartla).  This  course  of  events  may  l)e  interrupted  by  vigorous  treat- 
ment of  both  parents.  Rarely  luetic  children  are  born  of  ajjparently  sound  par- 
ents. Engman  suggests  that  in  such  ca.ses  the  mother  may  Ix'  a  ''spirochete 
carrier." 

Still  more  rarely  apparently  healthy  children  are  born  of  syi)hilitic  mothers. 
Why  the  placenta  does  not  allow  the  virus  access  to  the  fetus  is  not  kncjwn,  n(jr  is  the 
manner  of  infection  of  the  fetus  settled — whether  it  is  jjrimarily  ovular  or  lat<'r  by 
placental  transmission.  Spirocheta'  have  been  found  in  the  ova  in  the  ovary  of 
the  fetus.  Ruge  says  that  83  per  cent,  of  repeatetl  abortions  are  due  to  sj-philis. 
Late  abortion — fifth  to  seventh  months — ami  early  premature  labor — seventh  to 
eighth  months — are  characteristic  of  syphilis.  Hydrocephalus,  spina  bifida,  de- 
formities in  the  nervous  system,  polydactylia,  etc.,  are  often  due  t(j  syphilis 
(Rudaux,  Rosinski). 

If  the  woman  acquires  syphilis  at  the  time  of  conception,  early  alx>rtion  is  the 
rule,  unless  thorough  treatment  is  given  at  the  start,  and  even  then  the  child  is  often 
lost.  If  the  sy])liilis  is  contracted  during  ])regnancy,  Ixjth  parents  having  been  well 
at  the  time  of  impregnation,  that  is,  post-conce])tional  inf<'ction,  abortion  is  the 
rule  in  the  early  months,  l)ut  if  the  disease  wa.s  acciuired  in  the  latter  months,  the 
child  may  escape,  the  placenta  olTering  a  barrier  to  the  virus.  In  such  instances 
the  child  may  be  immune  (Profeta's  law).  Later  studies  show  that  these  infants 
have  a  positive  Wassermann  reaction.  In  more  than  half  the  cases  the  fetus  ac- 
quires the  disease  tiirough  the  jilacenta,  even  in  the  last  month  (Finger),  or  even 
during  its  transit  through  the  birth-canal. 

Interruption  of  gestation  is  the  commonest  symptom,  and  von  Winckel  found 
Gl  jx'r  cent,  fetal  mortality.  It  is  said  that  eclampsia  is  not  more  conunon,  but 
the  author  had  three  women  showing  marked  alljuminuria  while  carrying  syjihilitic 
fetuses.  Labor  may  be  influenced  by  syphilis.  The  pains  may  be  weak  and  prog- 
ress slow.  Abnormal  presentations  are  common,  because  the  children  are  usually 
macerated.  A  chancre  on  the  cervix  may  imix^de  delivery,  as  also  may  an  indura- 
tion in  the  secondary  .stage  (Rlandin),  which  may  necessitate  incisions,  craniot- 
omy, even  cesarean  section.  Friability  of  the  perineum  was  very  pronounced  in 
three  of  my  cases,  the  head  bursting  through  the  vulva,  tearing  it  in  all  directions 
like  wet  paper.  Condylomata  lata  vulva?  conduce  to  such  lacerations.  Postpar- 
tum hemorrhage  is  usually  not  greater,  l)ut  the  author  had  one  ca.<e  of  hemophilic 
diathesis  in  a  syphilitic  prostitute  which  made  some  such  relation  seem  jjlausible. 
Ordinarily,  if  the  fetus  has  been  dead  long,  throml)osis  of  the  placental  site  occurs. 

In  the  puerperium  sepsis  is  not  commoner  than  usual;  the  pueriK»ral  wounds, 
unless  primarily  infected,  heal  nicely,  esix>cially  if  sjx^cific  treatment  is  given. 

I'ntvrtud  syphilis  has  also  a  bad  effect  on  gestation,  and  its  action  is  hard  to 
understand.  When  the  husband  has  florid  primary  or  secondary  syphilis  and  in- 
fects his  wif(>  at  the  time  of  imi)regnation,  it  is  imj)ossible  to  .sej^arate  the  results. 
Abortion  is  the  rule.  The  commonest  cases  are  those  where  the  husband  has  l>een 
treated  more  or  less  successfully  for  syi>hilis  before  marriage.  The  limit  of  safety, 
that  is,  the  time  re(iuired  Ix'fore  he  can  procreate  healthy  ofTspring.  is  varit)usly 
given  as  from  two  to  twelve  years,  but  much  dei>ends  on  the  success  of  the  treat- 
ment. Even  if  at  the  time  of  coitus  he  has  no  infective  lesions,  the  child  is  usually 
syphilitic,  or  it  maj-^  show  signs  of  the  disease  later  in  life.  If  the  father  was  cureil, 
it  will  remain  well.  If  the  lues  is  more  rect'ut  or  uncured,  the  child  dies,  macerates, 
and  ]iremature  lal)or  takes  jilact',  with  a  re|H>tition  of  such  an  occurrence  in  subs*^- 
quent  jiregnancies  until  the  virus  is  removed  by  time  or  medicines. 

How  do  the  spirochetal  reach  the  ovum?     They  are  three  times  larger  f haii  flic

head  of  the  spermatozoid,  and  surely  this  tiny  organism  could  hardly  carry  such  a 
load;  therefore  they  are  carried  by  the  semen.  Experience  and  experiment  have 
shown  that  s>T)hilis  can  thus  be  conveyed  (Bab),  but  it  is  more  likely  that  the 
mother  becomes  syphilitic  and  the  spirochetae  settle  in  the  ovum  and    decidua

from  the  blood.     Xoguchi,  by  cultivating  the  spirocheta',  ha.s  provccl  the  spccificitv 
of  the  organism  for  syphilis. 

A  woman  carrying  a  child  leutic  ex  patre,  as  a  rule,  becomes  iinniuiif  to  syj)hilis. 
(Abraham  CoUes'  law,  Dublin,  1837.)  We  know  now,  from  the  results  (jf  the  study 
of  the  women  and  infants  with  the  Wassermann  blood-test,  that  the  mothers  are 
innnune  because  they  are  really  syi)hilitic.  CoUes'  law  is  thus  up.set,  and  WolfT's 
dictum  of  1879  confirmed.  A  mother  carrying  an  ex  patre  syphilitic  fetus  some- 
times develops  actual  lesions  Avhich  may  be  secondary  and  tertiary,  or  even  only 
tertiary — the  "s^-philis  by  conception."  The  virus  has  ])assed  from  the  fetus 
through  the  placental  wall  to  the  mother.  It  is  certain  that  the  spirillum  of  relaps- 
ing fever  may  pass  the  placenta  ami  infect  the  child,  and,  therefore,  it  is  fair  to 
argue  that  the  Spirochseta  pallida  may  infect  the  mother  by  a  reverse  process.

arteries,  and  to  a  less  extent  the  umbilical  vein,  are  much  thickcnt^l,  even  obliterat«-<i,  a  fact 
which  may  be  usixl  for  diagnosis.  The  spiroeheta;  are  rare  in  the  plarvnta,  but  have  lje<-n  found 
in  the  liver,  spleen,  testicle,  ovary,  skin,  eye,  etc.  The  fetal  bl(j<j<l  shows  a  m(jnonuel«-ar  lympho-

The  diaphysis  breaks  off  easily.  Similar  changes  occur  in  congenital  rachitis,  but  a  glance 
at  Fig.  4.3.")  will  enable  a  differentiation  to  be  made. 

Syphilis  has  been  invoked  to  explain  many  diseases  of  the  new-bom,  for  example,  icterus 
gravis,  hemorrhagic  diathesis,  hyilrocejjhalus,  congenital  deformities,  cystic  kidneys,  athrep.sia. 
Perhaj)s  the  discovery  of  the  spiroeheta  and  the  various  serum  reactions  may  bring  "light  in  these 
and  other  conditions. 

Treatment. — Sj^Dhilis  is  to  ])e  thoroughly  treated  as  soon  as  discovered,  and 
in  the  u.sual  manner,  regardle.ss  of  pregnancy.  In.stituted  earlj',  abortion  may  l)e 
prevented.  Salvarsan  and  inunctions  seem  to  give  the  best  results.  Habitual 
abortion  after  the  fifth  month,  or  premature  labor,  when  due  to  syphilis,  indicate 
anti.sy])hilitic  treatment  of  both  parents.  In  doul)tful  ca.<;es,  too,  this  advice  may 
be  given.  It  is  the  author's  practice  to  give  women  with  such  a  hi.story,  during  preg-

X liming. — (July  its  mother  may  nurse  the  infant,  becatLse  the  chikl  is  almost 
invariably  di.seased,  even  if  it  shows  no  evidences  of  lues.  Latterly  cases  are  being 
published  in  which  a  luetic  mother  infected  her  previously  healthy  child;  but  these 
ca.ses  are  rare.  The  milk  of  a  luetic  woman  is  infectious.  If  the  chiUl  is  .syphilitic

nurse.  It  is  criminal,  though  the  law  allows  only  damages  from  a  civil  suit.  In 
hospitals  and  in  maternities  the  authorities  must  be  on  guard  constantly  for  this 
danger.  Only  after  most  careful  investigation,  including  the  ."^erum  reaction,  has 
shown  that  the  baby  and  the  wet-nurse  are  healthy  may  nursing  Ik*  allowed.  In 
general,  in  maternities,  the  j^hysicians  antl  nurses  should  constantly  watch  for  the

has  escaped  infection  (Zeisler,  Zeit). 

DISEASES  OF  THE  CIRCULATORY  SYSTEM 
The  Heart. — There  is  no  doulit  that  the  heart  regularly  suffers  an  alteration 
as  the  result  of  gestation.     It  hypertrophies,  it  tlilates,  or  does  both,  and  \ii<  liow 
foimd  .slight  evidences  of  fatty  degeneration. 

In  tlie  routine  examination  of  the  hearts  of  pregnant  women  the  auliiur.  in  a 
majority  of  the  ca.-^es,  has  found  .systolic  murmurs  at  the  l)a.se  and  accentuation  of 
the  second  aortic  sound,  occasionally  a  presystolic  murmur,  and  displacement  of  the 
ape.\-beat  to  the  left.  It  was  not  always  ea.sy  to  eliminate  actual  vitium  conlis. 
Several  real  heart  thseases  were  chseovered,  which,  without  such  a  routine  c.xamina-

tion,  would  surely  have  passed  through  labor  without  being  noticed,  l)ecause  they 
produced  no  trouble  whatever.  Heart  disease  in  labor  is  certainly  often  overlooked. 
•  The  Effect  of  Pregnancy  on  Heart  Disease. — A  normal  health}^  heart  easily  satis- 
fies all  the  extra  demands  made  on  it  by  gestation  and  labor.  Even  a  diseased  heart, 
if  compensation  is  good,  often  sustains  the  additional  strain  without  laboring  hard. 

Pregnancy,  therefore,  in  mild  heart  cases,  in  young,  otherwise  healthy  women, 
does  not  seem  to  exert  a  very  harmful  influence  on  the  disease,  but  it  has  seemed  to 
the  author  that  these  women  develop  cUscompensation  and  die  sooner  than  other 
women,  and  men  with  similar  cardiac  disease.  Naturally,  it  is  hard  to  collect 
statistics  on  this  point.  If  the  disease  is  advanced;  if  the  heart  is  in  unstable 
equilibrium,  and  especially  if  myocarditic  or  fatty  degeneration  has  occurred,  the 
danger  of  broken  compensation  with  its  pernicious  sequelae  is  present.  Pregnancy 
predisposes  to  an  acute  exacerbation  of  chronic  endocarditis,  especially  if  the  latter 
be  not  too  old,  and  with  this  sometimes  a  fatty  degeneration  of  the  papillary  muscles, 
which  has  a  bad  effect  on  the  compensation.  The  congestion  of  the  venous  system 
leads  to  kidney  and  hepatic  disturbances;  the  pulmonary  congestion  leads  to 
dyspnea  and  carbonic-acid  narcosis,  and  the  high  position  of  the  diaphragm,  with 
the  slight  decrease  of  vital  capacity,  augments  the  respiratory  difficulty  and  cyanosis. 
Transudations  in  the  pleurae  may  cause  compression  of  the  lungs,  hypostatic  pneu- 
monia, and  oedema  pulmonum,  and  hemoptysis  may  also  be  a  complication.  Edema 
of  the  extremities,  ascites,  dyspnea,  attacks  of  suffocation,  dry  cough,  palpitation, 
insomnia,  albuminuria^all  these  show  that  the  compensation  is  broken  and  warn 
the  accoucheur  of  impending  danger. 

During  Labor. — There  is  danger  from  not  fully  compensated  hearts,  and,  too, 
an  apparently'  competent  heart  may  suddenly  prove  default.  Without  doulit  some 
of  the  cases  of  sudden  death  during  labor  are  due  to  an  unrecognized  vitium  cordis. 
I  have  seen  two  cases  of  acute  dilatation  of  an  apparently  normal  heart,  but  prob- 
ably unsuspected  myocardial  disease  was  present.  Even  a  strong  heart  may  not 
be  able  to  stand  the  strain  of  an  unduly  prolonged  second  stage. 

Uterine  action  increases  the  arterial  tension,  and  straining — bearing  dowTi — 
increases  both  arterial  and  venous  pressure.  In  themselves  these  are  not  very 
dangerous;  it  is  the  fluctuation  of  the  blood-pressure  incident  to  labor  which  is 
hard  on  the  heart.  Symptoms  of  a  laboring  organ  appear,  or  the  heart  may  sud- 
denl}'  give  way  to  the  strain,  and  c^^anosis,  collapse,  oedema  pulmonum,  and  death 
ensue.  If  the  heart  holds  out  until  the  baby  is  born,  the  balance  of  the  circulation 
may  be  established  rapidly,  or,  in  not  a  few  cases,  sudden  death  in  collapse  may 
occur.  In  one  of  the  cases  seen  by  the  author  in  consultation  the  fatal  collapse 
occurred  three  hours  after  delivery. 

Di  the  yuerperium  some  of  the  patients  that  recover  from  the  strain  of  labor 
grow  worse,  and  die  from  embolism  of  the  brain  or  lungs,  cardiac  thrombosis, 
recurring  endocarditis,  degeneration  of  the  heart  muscle,  and  aggravation  of  the 
existing  disease.  Sepsis  in  the  puerperium  favors  acute  endocarditis,  or  may 
cause  exacerbations  of  an  old  affection. 

Valvular  lesions  are  less  affected  by  gestation  than  the  myocardial  diseases,  a 
point  which  Angus  MacDonald,  Berry  Hart,  and  others  have  emphasized.  This 
table  is  compiled  from  statistics  of  Fellner,  Porak,  and  Vinay,  and  shows  the 
relative  frequency  of  the  several  affections.

DISEASES    OF   THE    CIKCULATORY    SYSTEM  489 

A  second  class  of  cases  is  composed  of  those  that  d<*veloj)(hirin|^  j)regiiancy  and 
the  puerperiuni.  It  was  once  thought  tliat  a  siil)acute  endocarditis  was  pecuhar  to 
Ijresnuncy,  Ijut  tliis  is  not  considered  any  longer.  Acute  endocarditis  may  occur 
during  i)reji;nancy.  Acute  myocartUtis  and  fatty  defeneration  may  occur  duriuK 
gestation.  I)ut  they  are  more  hkely  in  tiic  puerpcrium,  as  evidences  of  a  septic  \)U)v- 
ess,  though  tiiey  may  (K-cur  alone.  Brown  atrophy  has  been  found  in  many  cases 
of  sepsis.  P'atty  degeneration  of  the  heart  may  follow  severe  hi-morrhages,  es- 
pecially if  repeated,  also  i)rolonged  and  hard  labor,  j)rotracted  chlonjform  narcosis, 
and  there  has  been  observed  an  acute  general  fatty  degeneration  similar  to  liuhl's 
disease  of  the  new-born.  Heart  cases  are  aggravated  by  the  comj)licati(»ns  of  preg- 
nancy, for  exami)le,  twins,  jjolyhytlranmion,  contracted  j)el\is.  1iiberculo>is.  tox- 
emia, nejihritis,  etc. 

Effects  of  the  Heart  Disease  on  Pregnancy. — Sterility  is  not  comm(»n  in  W(»men 
witli  cardiac  lesions  unless  in  advanced  stages.  Profuse  menstruation  has  l»een 
noted.  Abortion  and  i)remature  lalK)r,  es])ecially  the  latter,  occur  in  ca.ses  of  dis- 
compensation,  in  from  20  to  40  per  cent.,  and  still-births  in  29  to  70  per  cent.,  giving 
the  figures  collected  from  various  sources  by  Fellner.  Labor  is  often  slow,  the  pains 
not  good,  and  ojK'rative  interference  connnoner.  It  is  said  that  i>ostpartum  hemor- 
rhage is  fre(iuent,  but  I  have  not  found  it  so.  Its  gravity  in  heart  cases  is 
variously  gaged,  some  authors  even  considering  it  beneficial.  Placenta  margin- 
ata  is  conunon.  Heart  disease  has  no  i)articular  influence  on  the  i)ueri)eral  proc- 
esses.    The  lochia  are  somewhat  profuse  and  i)rolonged,  and  lactation  is  imjx'rfect. 

Pnxjnosis. — Since  many  women  with  cardiac  disease  ])ass  through  ])regnancy 
and  lal)or  with  the  contlition  unknown,  it  is  necessary  to  receive  the  published  ac- 
counts with  caution.  Published  statistics  of  mortality  are,  34,  Gl,  GO,  55,  48,  49, 
12,  G,  31,  and  85  per  cent.,  and  these  surely  present  a  dark  j)icture  of  the  gravity  of 
cardioi)atliy  in  ])regnancy,  but  Fellner,  who  collected  the  above,  calls  attention  to 
the  fact  tiiat  these  are  only  the  bad  cases,  and  that  the  many  mild  ones  are  not  re- 
jjorted,  and  supports  the  statement  with  the  figures  of  Schauta's  clinic,  which  showed 
a  mortality  of  G.3  per  cent.,  and,  if  he  reckonetl  in  those  ca.ses  wherethe  vitium  was 
accitlentally  iliscovered,  it  would  be  only  0.9  per  cent.  Nevertheless,  my  own  ex- 
perience has  taught  me  to  fear  the  comjilication  of  heart  disease  with  jiregnancy.  for 
even  though  one  finally  brings  the  patient  through  alive,  the  dangers  that  tlireaten 
at  ever}'  step  are  very  disquieting,  and  when  accidents  occur,  they  re<iuire  the 
promptest  and  most  skilful  treatment.  Mitral  stenosis  is  generally  considered  the 
worst  of  the  valvular  diseases,  so  far  as  ]iregnancv  is  concerned,  especially  when 
comjilicated  ])y  myodegeneration,  which  makes  all  cases  very  serious.  Everything 
dei)ends  on  tlu*  compi'usation.  In  uncomi)ensated  heart  disea.se  many  children  die 
from  prematurity,  abruptio  placentie,  disease  of  the  jilacenta,  and  iLsi)hyxia,  be- 
cause of  the  imperfectly  aerateil  maternal  blood  and  carbonic  acid  narcosis. 

Trcdtmcnt. — A  woman  with  uncomjx'nsated  heart  disease  should  not  marry,  anil 
if  marrii'd,  should  not  conceive,  and  if  siie  has  a  baby,  should  nurse  it  «inl>-  in  i)art. 
If  the  woman  is  otherwise  healthy,  that  is,  has  good  lungs,  liver,  kidneys,  etc..  and 
her  heart  is  carrying  its  burden  well,  she  may  marry,  and  if  she  nuich  desires  it, 
have  children,  but  the  dangers  are  to  be  explained  to  both  husband  and  wife. 
Rarely  is  the  physician  consulted  until  ])regnancy  has  occurred.  In  itself.  In-art 
disease  is  no  indication  for  abortion,  yet  if  a  woman  with  chronic  discompensation, 
with  myodegeneration,  with  liver  or  kidney  insufficiency,  becomes  pregnant,  it 
may  be  necessary  to  emjity  the  uterus  very  early,  becausi'  we  know  she  will  not  l>e 
able  to  go  through  the  jirocess  safely.  Kxpi'ctancy  is  the  rule,  but  the  woman  must 
be  under  medical  surveillance.  Patients  with  heart  lesions  should  take  a  small 
amount  of  outdoor  exercise  (>ach  day.  should  not  oven'XtTt  nor  get  excite«l.  should 
avoid  crowds,  overeating, and  alcohol — in  short,  should  pursue  a  (|uiet, normal  ctmrse 
of  life.     On  th(>  first  signs  of  discomi>ensation  they  should  rest  in  bed  a  few  days 


•490  THE    PATHOLOGY   OF    PREGNANCY,    LABOR,    AND    THE    PUERPERIUM 

under  restricted  fluids  and  simplified  diet.  If  the  heart  needs  help,  digitalis 
in  small  doses  may  be  useful.  For  suffocative  attacks  morphin  hypodermically — 
in  short,  the  usual  treatment — is  to  be  given.  Should  the  symptoms  aggravate 
and  the  heart  begin  to  show  its  overstrain,  labor  is  to  be  induced.  I  am  aware  that 
many  authors  oppose  this  on  the  ground  that  labor  is  usually  the  cause  of  colhipse, 
and  that  the  deaths  often  occur  in  the  early  j)ueri)erium,  but  this  reasoning  has 
always  seemed  to  me  peculiar.  The  pregnancy  is  evidently  aggravating  the  lesion, 
the  heart  is  pro\ing  default,  the  woman  must  go  through  her  labor  sooner  or  later, 
and  if  she  is  getting  worse  in  spite  of  treatment,  she  will  be  less  and  less  able  to 
withstand  the  strain  the  longer  the  interference  is  decayed.  The  urgency  of  the 
sjT^nptoms  A^T.11  decide  the  choice  of  method.  In  cases  of  imminent  danger  puncture 
the  bag  of  waters,  and  as  soon  as  preparations  can  be  made,  empty  the  uterus  by 
vaginal  cesarean  section.  If  there  is  no  occasion  for  great  hurry,  pack  the  cervix 
and  lower  uterine  segment  with  gauze.  If  no  pains  are  set  up,  remove  in  twenty- 
four  hours,  puncture  the  memljranes,  and  put  in  a  small-sized  colpeurynter.  A 
woman  ■\\dth  heart  disease  should  never  be  allowed  to  go  beyond  term. 

During  labor  all  heart  cases  require  close  scrutiny,  even  if  there  is  good  com- 
pensation. Labor  must  be  so  conducted  that  collapse  in  the  third  stage  and  sudden 
death  later  in  the  puerperium  are  rendered  impossible — a  task  of  no  small  difficulty. 
Preparations  for  all  eventualities  must  be  made  beforehand — plenty  of  assistants, 
oxygen,  salt  solution,  venesection  instruments,  hypodermic  syringe  with  stimu- 
lants— in  short,  the  facilities  of  a  well-equipped  maternity.  All  the  instruments  for 
operative  delivery  are  to  be  held,  sterilized,  ready  for  instant  use.  "Watch  the  effect 
of  the  pains  on  the  heart,  such  as  cyanosis,  flagging,  or  irregular  pulse.  Dyspnea 
between  pains  is  suggestive.  Digitalis  may  be  given  during  labor.  "When  dilata- 
tion is  complete,  puncture  the  membranes,  but  let  the  water  escape  slowly.  As  the 
head  comes  down  on  the  perineum  watch  the  effect  of  the  bearing-down  efforts  on 
the  heart.  Even  if  the  dyspnea  is  not  very  marked  nor  the  cyanosis  very  deep;  if 
cough  sets  in;  if  the  pulse  begins  to  drop  beats;  if  it  gets  very  rapid— 108  to  130; 
if  the  bearing-down  efforts  do  not  produce  regular  and  decided  advancement  of  the 
child,  extract  at  once.  Do  not  wait  for  actual  edema  of  the  lungs  or  actual  cardiac 
failure  to  spur  you  to  action,  because  in  such  cases,  even  if  you  do  save  the  patient, 
the  time  that  the  circulation  has  been  in  abeyance  has  perhaps  allowed  a  clot  to  form 
in  the  heart,  or  the  overstrain  of  the  muscle  has  caused  a  hemorrhage  in  the  myo- 
cardium, and,  later  in  the  puerperium,  death  may  occur  from  embolism  or  cardiac 
rupture.  Extraction  is  done  by  forceps  or  by  the  breech,  depending  on  conditions, 
but  the  actual  delivery  is  to  be  executed  slowly,  and  two  strong  hands  must  follow 
down  the  uterus,  so  that  the  intra-abdominal  pressure  is  not  reduced  too  quickly, 
since  the  rush  of  blood  into  the  dilated  veins  of  the  abdomen  would  tend  to  leave  the 
enlarged  heart  empty.  Some  authors  recommend  that  the  woman  be  allowed  to 
bleed  freely  in  the  third  stage.  I  do  not  believe  it  is  wise,  and  permit  it  only  in  cases 
of  mitral  stenosis,  and  where  the  pulmonarj^  circulation  is  evidently'  overloaded. 
Delivery  of  the  placenta  should  not  be  hastened.  Ergot  may,  if  necessary,  be 
given  after  the  third  stage.  Ether  is  the  anesthetic  of  choice,  a  professional  an- 
esthetizer  being  employed,  if  possible,  since  this  will  enable  the  accoucheur  to  give 
all  his  attention  to  the  delivery  of  the  child.  In  myodcgeneratio  cordis  it  is  best 
to  give  no  anesthetic,  and  I  have  been  surprised  to  see  how  much  could  be  accom- 
plished by  encouragement  and  suggestion. 

Should  collapse  occur  at  any  time  during  the  first  stage,  it  nmst  be  combated 
instantly,  for  reasons  above  given,  and  labor  should  be  completed  by  bimanual  dila- 
tation, cervical  incisions,  or  even  the  vaginal  cesarean  section.  When  the  fetus  is 
dead,  craniotomy'  is  to  be  done,  "While  doing  these,  or  after  delivery,  give  hypo- 
dermically .30  minims  of  camphorated  oil,  then  30  minims  of  tincture  of  digitalis  (or 
1  c.c.  of  digalen  intravenously),  oxygen  by  inhalation,  and  6  ounces  of  strong  black

coffee  per  rectum.  A  very  lijfht  iilnloiniiial  binder  is  applied,  <jr  a  sand-hap;  laid  on 
the  belly.  For  a'dema  puhnonuni  the  same  treatment  is  given.  \'enesection  may 
be  useful  when  the  heart  is  overenmorged,  8  to  12  ounces  being  withdrawn.  Thougli 
used  in  otiier  iieurt  ca.ses,  I  iuive  never  found  it  neces.sary  under  the.se  circumstances. 
Salt  solution  is  not  to  Ijc  given  in  these  cases  unless  complicated  by  severe  hemor- 
rhage. Since  the  most  critical  period  is  ju.st  after  delivery,  a  physician  should  re- 
main near  the  patient  for  at  least  twelve  hours.  In  the  pueri)erium  ab.solute  rest, 
with  the  body  horizontal,  the  head  a  little  raised,  and  the  exhibition  of  the  u.sual 
remedies,  are  advi.sed.  Nursing  is  to  be  prohibiteil  only  in  bad  cas<'s,  Ijut  it  is 
always  best  to  substitute  i)art  of  the  feeding  to  prevent  too  great  a  drain  on  the 
woman's  resources. 

Basedow's  Disease. — Palpitation  of  the  heart  is  ncjt  infrequent  during  gesta- 
tion, cau.sed  by  indigestion,  toxemia,  exercise,  or  by  a  i)ure  neurosis.  I  have  seen 
not  a  few  cases  wiiere,  during  i)regnancy,  tachycaniia,  nervousness,  struma,  and 
slight  exoplithalmos  have  raised  strong  suspicions  of  Basedow's  disease,  but  the 
symptoms  disappeared  later.  These  may  be  toxemic  in  nature.  Indeed,  many 
cases  of  true  Graves'  lUsease  show  symptoms  which  we  find  in  the  pregnancy  to.x- 
emias.  On  the  other  hand,  clinically  tyjiical  (Iraves'  disease  occurs  during  gesta- 
tion, antl  perhaps  more  frecjuently  than  the  literature  would  indicate.  It  seems  to 
the  author  that  pregnancy  brings  out  the  latent  afifection,  but  rarely  causes  serious 
aggravation  of  the  symptoms  unless  toxemic  conditions  are  added  as  a  complication. 
Sometimes  pregnancy  ameliorates  the  symptoms,  the  fetus  taking  uj)  the  excess  of 
thyroid  secretion.  Kepeated  pregnancies  usually  have  a  bad  effect.  Hirst  had  a 
patient  in  whom  the  disease  recurred  in  three  successive  jiregnancies.  Labor  does 
not  produce  serious  trouble,  except  in  the  advanced  cases,  and  then  the  conditions 
are  the  same,  and  one  treats  them  the  same  as  heart  lesions.  The  pueqierium  exerts 
no  special  influence,  though  sometimes  the  cour.se  of  the  disease  continues  downwartl 
during  this  time. 

Amenorrhea  and  sterility  are  common  in  women  suffering  from  exophthalmic 
goiter,  because  of  the  atrophy  of  the  uterus  and  ovaries.  Pregnancy,  however,  has 
occurred  during  the  amenorrhea.  Abortion  is  not  usual  unless  the  cardiac  di.s- 
compensation  is  marked.  In  bail  cases  death  of  fetus  and  premature  labor  may 
occur.  Labor  is  uninfluenced  by  the  disease,  but  it  is  said  that  abrupt io  placentie 
and  postpartum  hemorrhage  are  more  frequent  (White).  Hj-perinvolution  is 
common.  Lactation  is  likely  to  be  imperfect,  and  only  few  cases  show  oversupi)ly 
of  milk.  The  fetus  is  usually  healthy.  Thyroid  secretion  jia.sses  over  to  the  child 
in  the  milk.  Graves'  disease  is  exceedingly  rare  in  infants,  only  one  ca.se  at  four 
weeks  being  on  record. 

The  treatment  of  the  disease  is  the  same  as  if  the  woman  were  not  i)regnant.  and, 
in  general,  what  was  said  of  the  care  of  heart  ca.ses  in  pregnancy  applies  here.  Abor- 
tion may  be  required  if  the  heart  proves  default  early,  and  especially  if  toxemic 
symptoms  predominate,  though  pi'rliajjs  ligation  of  the  upper  i)oles  of  the  gland,  or 
partial  removal,  might  hold  the  disease  in  check  until  pregnancy  has  been  com- 
pleted. Late  in  pregnancy  the  symptoms  may  demand  interference,  l)ut  emptying 
the  uterus  does  not  produce  the  same  relief  as  in  pure  heart  ca.ses,  U'cause  the  tox- 
emia and  hyperthyroidism  i)ersist.  The  slower  methods  of  tlelivery  are  to  1m'  pre- 
ferred unless  lai)or  drags  on,  when  cervical  incisions  or  vaginal  cesarean  section  may 
be  needed.  Pregnancy  shouki  never  be  allowed  to  go  Ix'vond  term.  Mt)r|>hin,  n'st 
in  bed,  and  an  ice-bag  over  the  heart  are  used  to  calm  tlie  cardiac  action.  Ktlier  is 
the  best  anesthetic. 

Phlebitis,  periphlebitis,  thrombosis  of  the  heart  and  of  the  veins  of  the  legs,  all 
of  which  may  occur  tluring  pregnancy,  will  I)e  considrn-d  under  the  Puerjxral 
Diseases. 


492  THE    PATHOLOGY   OF   PREGXANCY,    LABOR,    AND    THE    PUERPERIUM 


DISEASES  OF  THE  ALIMENTARY  TRACT 

Mild  disturbances  of  the  intestinal  tract  are  very  common  during  gestation. 
Nausea  and  vomiting  have  already  been  discussed,  and,  under  the  Hygiene  of  Preg- 
nancy, the  treatment  of  constipation  has  been  considered. 

Gastric  and  intestinal  indigestion  are  of  frequent  occurrence,  and  yield  very 
slowly  to  the  usual  remedies.  For  the  acidity  of  the  stomach  soda-mint  tablets, 
milk  of  magnesia,  or  efiervescent  jihosphate  of  soda,  may  ])e  used.  In  a  few  cases 
slowly  sucking  pure  rock-candj'  or  chewing  salted  nuts  until  fine  has  been  helpful. 
Sodium  bicarbonate  and  magnesia  usta  are  also  useful  for  the  "heartburn."  For 
the  colicky  pains  a  dose  of  Rochelle  salts  combined  with  proper  dieting  does  the 
most  good,  but  it  may  be  necessary  to  give  a  sedative — sodium  l)romid,  15 
grains  thrice  daily  in  syrup  of  red  raspberry,  after  meals.  It  may  not  always  be 
eas}'  to  differentiate  between  intestinal  and  uterine  or  tubal  colic  (ectopic  gestation). 
Bimanual  examination  will  clear  the  diagnosis.  Colics  due  to  intestinal  adhesions, 
resulting  from  the  so  common  abdominal  operations  of  today,  are  verj'  rebellious 
to  treatment. 

Flatulence  causes  colic,  and  may  itself  be  very  annoying.  Proper  diet  and 
movement  of  the  bowels,  with  5  grains  of  salol  and  15  grains  of  charcoal  three  times 
a  day,  will  usually  give  relief.  Diarrhea  as  a  special  symptom  is  rare.  I  have  fre- 
quently ol>served  it  as  a  prodrome  of  labor.     Treat  according  to  cause. 

Toothache  and  dental  caries  are  common,  perhaps  as  the  result  of  a  mild  form 
of  osteomalacia,  to  which  reference  has  already  been  made.  So  common  is  dental 
caries  that  there  is  an  old  saying — ''for  every  child  a  tooth."  Neuralgia  of  the 
teeth  is  also  noted  in  gestation,  and  is  usually  due  to  an  infected  cavity  or  sinus 
disease.  Before  teeth  are  extracted  the  patient  is  to  be  examined  by  a  surgeon 
capable  of  detecting  these  obscure  causes.  Dental  neuralgia  ma}'  indicate  the 
toxemia  of  pregnancy.  Teeth  that  are  hopelessly  diseased  and  infected  are  to  be 
removed,  and  experience  proves  that  nitrous  oxid  gas  may  safely  be  used.  It  is 
more  than  possible  that  some  obscure  puerperal  infections  have  their  ultimate  origin 
in  abscessed  teeth. 

Jaundice. — Hepatic  insufficiency  is  now  fully  recognized  as  a  cause  of  many  of 
the  disorders  incident  to  pregnancy,  under  which  heading  they  are  considered. 
Icterus  gravis  gravidarum,  or  acute  yellow  atrophy  of  the  liver,  has  been  described. 
Epidemics  of  infectious  jaundice  have  been  observed,  and  when  pregnant  women 
are  affected,  they  show  a  high  mortality.  Catarrhal  jaundice  is  rare  in  gesta- 
tion. In  the  service  of  the  Chicago  Lying-in  Hospital,  now  over  15,000  cases,  it 
occurred  but  five  times.  No  special  significance  attaches  to  catarrhal  jaundice, 
except  to  call  our  attention  to  the  liver  and  to  the  necessity  of  making  sure  that  it  is 
only  a  simple  affair  with  which  we  have  to  deal.  In  ectopic  pregnancy  jaundice 
sometimes  appears.  Jaundice  occurring  just  before  or  during  labor  is  verj'  signifi- 
cant. (See  Acute  Yellow  Atrophy.)  Jaundice  may  be  observed  after  delivery 
when  general  anesthesia  has  been  used,  especially  after  chloroform.  One  should 
think  of  late  chloroform  poisoning,  that  is,  liver  autolysis.  The  child  delivered 
from  a  jaundiced  mother  is  not  icteric. 

Gall-stones. — It  seems  that  pregnancy  is  a  factor  in  the  development  of  gall- 
stones, and  it  is  not  rare  that  the  gravida  has  attacks  of  biliary  colic.  These  seldom 
occur  before  the  fifth  month,  and  jaundice,  with  chills  and  fever,  is  more  common 
than  in  the  non-pregnant  state.  Lal^or  may  cause  pain  in  the  full  gall-])ladder,  and 
the  latter  maj^  be  easily  palpated  during  the  third  stage.  In  the  pueii^erium 
attacks  of  gall-stones  are  infrequent.  I  have  observed  two  cases,  in  one  of  which 
the  symptoms  were  very  stormy,  with  intense  pain,  collapse  and  vomiting,  so  that 
suspicion  of  the  rupture  of  an  abdominal  viscus  could  well  be  entertained.  Opera- 
tion should  be  postponed,  if  possible,   until  after  delivery,  at   least  as  late  in 


DISEASES    OF    THE    ALIMENTARY    TRACT  493 

pregnancy  as  possible,  hecause  premature  labor  may  occur  and  the  child  be  lost. 
However,  the  later  operation  is  made  technically  difficult  by  the  large  uterine 
tum(jr.  Only  that  operation  should  be  done  which  will  (juickest  remove  dangerous 
conditions  (Peterson). 

Cholecystitis  may  complicate  pregnancy,  labor  frupturc),  and  the  puerperium. 
The  symptoms  are  (juite  stormy  and  jaundice  common.  It  is  better  to  wait  until 
after  delivery  for  the  operation,  if  po.ssible,  but  in  the  presence  of  a  strict  indication, 
for  example,  a  large  empyema,  one  may  have  to  drain  the  .sac  before  labor.  In  one 
ca.se  the  author  had  to  make  a  differential  diagnosis  between  puerix-ral  infecticjn 
and  pus  in  the  gall-bhuldcr  icf.  Vinebcrg).  Ab.scnce  <jf  local  evid«'nces  (jf  pucrp<Tal 
disease,  signs  of  local  jn'ritonitis  in  the  upper  abdomen,  with  appropriate  history, 
usually  indicate  the  exact  .source  of  the  trouble. 

Appendicitis. — Many  pregnant  women  complain  of  pain  in  the  region  of  the 
appendix,  and  it  is  possible  that  the  rising  uterus  draws  on  C(jmplicating  peritoneal 
adhesions.  Wcjmen  who  have  had  appendix  operaticjns  alnujst  always  comi)lain 
of  dragging  i)ains,  especially  from  the  fifth  to  the  eighth  months.  Primary  ai>- 
pendicitis  is  very  rare,  but  recurrent  disease  is  not  rare  during  gestation,  the  latter 
being  usually  the  catarrhal  variety,  and  seldom  causing  real  trouble. 

Perfcjration  antl  sujii^urative  peritonitis  are  very  nmch  m<jre  serious  than  out- 
side of  pregnancy,  because — (1)  Protective  adhesions  are  less  likely  to  be  formed; 

(2)  the  inflammation  is  more  stormy,  owing  to  the  inten.se  vascularity  of  the  parts; 

(3)  thrombosis  and  phlebitis  are  commoner;  (4)  suppuration  takes  place  higher  in 
the  abdomen  (true  of  late  pregnancy),  which  portion  is  recognized  to  be  less  re- 
sistant ;  (oj  drainage  is  less  free,  owing  to  the  large  uterus  near  by,  and  the  absces.>;es 
burrow  deeply  in  all  directions;  (6)  tympany  compromises  the  respiration  sooner, 
and  (7)  obstructive  symptoms  arise  earlier.  The  mortality,  according  to  Schmid, 
who  collected  486  cases,  is  verj'  high.  Appendicitis  offers  a  better  outlook  the  earlier 
in  pregnancy  it  occurs  and  the  sooner  it  is  recognized.  During  lal)or  the  contract- 
ing uterus  may  rupture  the  pus-sac  or  tear  an  adherent  or  perforating  appendix, 
with  resulting  general  peritonitis,  which  may  be  mistaken  for  sepsis  suljpartu. 
This  danger  is  greatest  during  the  third  stage  and  during  the  first  few  days  of  the 
puerperium,  at  w'hich  times  the  uterine  fundus  makes  its  greatest  excursions.  In 
the  puerperium  acute  appendicitis  is  easily  mistaken  fi^r  an  infection  of  the  tubes 
or  broad  ligament,  and,  indeed,  they  may  coexist.  The  puerperal  processes  ag- 
gravate the  appendiceal  disease. 

The  effects  of  perforative  appendicitis  on  the  pregnancy  are  al.so  marked,  abor- 
tion, premature  labor,  infection  of  the  uterine  contents,  and  death  of  X\\v  new-lMjrn 
child  being  noted  in  the  majority  of  cases.  This  might  all  be  forestalled  by  early 
operative  removal  of  the  infective  focus.  Labor  is  very  painful;  the  shock  of  it  is 
greater,  and  because  of  the  diseased  uterine  muscle  (contiguous  to  an  abscess)  weak 
l^ains  in  all  three  stages  are  ol)served.  Manual  removal  of  the  placenta  is  more 
often  needed,  and  such  brusk  manipulations  spread  the  pus.  On  the  jnieri)eriuni 
the  worst  influence  is  shown  when  the  disea.<ed  ai)i)endix  forms  adhesions  to  the 
tube  or  the  uterus,  direct  transmission  of  the  infection  being  thus  effected,  either 
through  the  walls  of  the  applied  organs  or  along  the  surface — rarely  through  the 
blood.  A  parametritis  may  also  be  caused  by  the  infection  creeping  through  ('la(h)'s 
ligament.  The  relics  of  apjx'ndicitis  may  anchor  the  uterus  in  an  unfavoral)le 
position,  may  occlude  the  tube,  producing  sterility  or  favoring  ectopic  gestation. 
On  the  other  hand,  I  am  convinced  that  tubal  infections  cau.se  apixMulicitis.  The 
frequency  of  appentlicitis  in  newly  married  women  is  striking,  and  the  gonococcus 
was  found  by  J.  H.  Hess  in  tiie  pus  from  an  api>endix. 

The  diagnosis  of  appendicitis  should  present  no  sjiecial  difficulties  if  only  the 
possil.nlity  of  its  occurrence  be  kept  in  miiul.  Kctojjic  gestation  (7.  v.)  and  twi.>it«Hl 
ovarian  tumor  come  up  for  consitleration,  but  most  mistakes  are  made  with  are- 


494      THE  PATHOLOGY  OF  PREGNANCY,  LABOR,  AND  THE  PUERPERIUM 

teritis  and  ureteral  stone  {q.  v.).  In  the  puerperium  sepsis  must  always  be  thought 
of,  and  only  a  laparotomy  may  explain  the  equivocal  symptoms.  A  worse  prog- 
nosis is  to  be  made  than  usual  because  nearly  40  per  cent,  of  perforated  appendix 
peritonitis  eases  die. 

As  yet  it  is  possible  to  lay  downi  rules  for  only  a  few  of  the  conditions  pre- 
sented for  treatment.  Recurrent  appendicitis  should  be  cured  before  pregnancy 
occurs.  A  woman  M-ith  only  a  historj'  of  appendicitis  should  not  be  operated  during 
pregnancy  unless  a  recurrence  takes  place.  A  mild  attack  should  always  indicate 
operation  in  the  first  five  months.  Only  perforative  disease  should  be  operated 
in  the  last  four  months,  and  then  as  soon  as  diagnosed,  but  in  cases  of  doubt  opera- 
tion is  the  safer  course.  The  incision  is  made  a  little  higher  than  ordinarilj',  and 
drainage  should  be  liberal.  Every  effort  should  be  made  to  prevent  premature 
labor.  Should  abortion  occur,  it  should  be  allowed  to  run  as  natural  a  course  as 
possible,  the  tampon  and  even  prolonged  expectancy  being  employed.  IManual 
curetage  is  to  be  replaced  by  instrumental  should  the  uterus  not  empty  itself.  The 
reason  for  this  is  evident — the  outside  hand  may  break  the  protective  adhesions 
around  the  abscess.  During  labor  the  same  rule  applies,  and  if  manual  removal  of 
the  placenta  is  necessary,  the  dangers  of  spreading  the  abdominal  infection  should 
be  borne  in  mind.  Xo  doul^t,  too,  genital  infection  is  favored  by  all  intra-uterine 
manipulations.  If  abortion  is  impending  at  the  time  of  operation,  the  uterus  should 
first  be  emptied,  and  then  drainage  of  the  abdomen  carried  out.  The  question  of 
emptying  the  uterus  artificially  before  operating  on  the  appendix  has  been  raised; 
even  cesarean  section  has  been  proposed  if  the  woman  is  near  term.  When  one  con- 
siders the  high  mortality  of  suppurative  peritonitis  at  or  near  term,  perhaps  it  would 
be  best,  in  the  interests  of  the  two  individuals,  to  remove  the  appendix  and  do  a 
Porro  cesarean  section  at  the  same  time.  I  believe,  in  cases  where  the  uterus  is 
opened  in  the  presence  of  pelvic  infection,  as  from  ruptured  appendix,  pus-tube,  or 
infected  tumors,  it  is  best  to  amputate  the  bulky  organ  and  drain  the  whole  pelvis 
freely  from  below.  If  the  operation  removed  an  acutely  inflamed  appendix  without 
adhesions  or  abscess,  it  is  not  advisable  to  empty  the  uterus  from  below  at  once, 
because  pregnancy  may  go  on  without  further  trouble,  and  if  a  walled-off  abscess 
has  formed,  it  is  dangerous  to  do  so,  because  during  labor  the  adhesions  always 
break.  With  free  drainage  and  the  use  of  opium  one  may  tide  the  woman  along  for 
several  days  and  thus  allow  the  sac  to  get  firm  and  the  amount  of  pus  in  it  to  be  re- 
duced. Obstetric  interference  may  thus  be  delayed  until  the  abscess  cavity  is 
granulating  safely  (Hilton,  Rudaux,  Babler,  Abrahams,  McArthur). 

Ileus,  a  rare  complication,  may  be  due  to  the  same  causes  which  produce  it 
outside  of  pregnancy,  or  may  be  due  to  compression  or  torsion  of  the  gut  by  the 
growing  uterus.  Naturall}',  the  gut  must  be  abnormally  adherent  for  this  to  take 
place.  In  one  of  the  author's  cases  an  old  appendicitis  was  responsible  for  the  ad- 
hesions, and  the  uterus  at  term  dragged  on  the  intestine,  producing  severe  pain  in 
the  right  iliac  fossa  and  almost  complete  obstruction — induction  of  labor,  recovery. 
If  the  ileus  is  due  to  a  complicating  suppurative  peritonitis,  premature  laljor  is  the 
rule  and  death  very  common  (Gauchery).  Treatment  is  the  same  as  in  surgical 
practice,  except  in  those  cases,  as  the  one  mentioned,  where  it  is  reasonable  to  be- 
lieve that  the  growing  uterus  is  the  acting  cause  of  the  obstruction ;  then  the  uterus 
is  to  be  emptied.  Ileus  after  delivery  may  be  due  to  the  trauma  of  labor,  to  ob- 
struction of  the  bowel  by  the  large  uterus  incarcerated  in  the  pelvis. 

Hernia  is  not  seldom  met  by  the  accoucheur.  Unless  the  gut  is  adherent,  the 
growing  uterus  pushes  the  contents  of  the  sac  out  and  away  from  the  hernial  open- 
ing, and  makes  a  temporary  cure,  but  the  ring  is  enlarged  by  tho  distraction  of  its 
pillars,  and  the  hernia  is  worse  in  the  puerperium,  though  incarceration  is  rare. 
Adherent  gut  may  be  incarcerated,  twisted,  or  stretched  even  to  the  production  of 
ileus.     During  labor  the  opening  is  usually  closed  by  the  large  uterus,  and  even  dur-

ing  strong  bearing-* lown  efforts  tin-  rupture  does  not  enlarge.  I  saw,  however,  an 
inguinal  hernia  (leveloj)  during  strong  expulsive  effort.  Treatment  of  hernia  is 
the  .same  as  at  any  other  time  when  threatening  symptoms  occur.  During  labor 
it  is  not  wi.se  to  allow  too  strong  effort  if  one  .sees  the  hernial  tumor  enlarging.  For- 
ceps should  be  applied  soon  after  the  dilatation  is  complete.  It  is  not  safe  t(j  hold 
the  gut  back  during  the  strong  exjjulsive  straining.  rml)ilical  and  j)ost-<jperative 
hernias  are  usually  permanently  enlarged  by  pregnancy,  and  traction  on  adherent 
omentum  often  causes  i)ain  (Manleyj.

CHAPTER  XXXIX 
DISEASES  OF  THE  URINARY  SYSTEM 

Nephritis. — Internists  distinguish  the  following  principal  forms  of  renal  dis- 
ease: Acute  nephritis,  chronic  nephritis,  of  which  there  are  two  grand  divisions,  the 
parenchymatous,  with  its  three  forms,  large  white  kidney,  large  red  kidney,  and  the 
secondary  contracted  kidney;  and  the  chronic  interstitial  or  primary  contracted 
kidney,  which  is  accompanied  by  cardiac  hypertrophy  and  a  general  arteriosclero- 
sis. The  accoucheur,  in  addition  to  these,  must  consider  the  kidney  of  pregnancy, 
its  aggravated  form,  the  so-called  pregnancy  nephritis,  and  the  kidney  changes 
which  are  part  of  eclampsia.  Since  even  the  internists  are  not  in  perfect  accord 
regarding  the  classification  of  their  physical  findings  and  admit  that  the  various 
recognized  varieties  of  disease  may  be  associated  or  correlated,  it  is  not  to  be  ex- 
pected that  the  accoucheur  will  be  able  absolutely  to  identify  the  many  conditions 
presented  to  him  for  treatment. 

The  kidney  of  pregnancy  and  the  kidney  in  eclampsia  have  already  been  con- 
sidered in  the  chapters  devoted  to  Incidental  Diseases.  Here  will  be  discussed 
the  accidental  complication  of  pregnancy  with  renal  disease.  Although  only  one- 
quarter  to  one-fifth  of  nephritics  develop  convulsions — perhaps  eclampsia — in 
pregnancy,  the  association  of  the  two  conditions  is  always  fraught  with  grave 
dangers  to  mother  and  child. 

Primary  acute  nephritis  may  develop  during  gestation  from  the  same  causes 
which  operate  outside  of  it,  for  example,  exposure  to  cold,  chemical  poisons,  pto- 
mainemia,  scarlatina,  angina,  and  septic  affections.  Antecedent  septic  processes 
make  the  kidney  more  vulnerable,  which  tendency  is  aggravated  by  pregnancy. 
Acute  nephritis  cannot  be  clinically  differentiated  from  the  "pregnancy  nephritis" 
which  often  leads  up  to  eclampsia,  and,  therefore,  will  not  be  further  discussed  here. 
(See  Eclampsia.) 

Chronic  'parenchymatous  nephritis  is  always  unfavorably  affected  ])y  the  advent 
of  gestation,  and  an  acute  exacerbation  is  almost  always  observed.  It  begins  to 
show  in  the  early  months,  contrary  to  the  renal  disease  incidental  to  pregnancy. 
Puffiness  of  the  eyelids  and  of  the  ocular  conjunctiva  and  general  anasarca  are  marked 
and  do  not  disappear  in  the  recumbent  position.  The  edema  aff"ects  the  legs,  which 
may  be  elephantiasic,  and  the  vulva,  which  may  be  transformed  into  two  immense, 
white,  translucent,  watery,  glistening  tumors.  Hydroperitoneum,  hydropleura, 
oedema  pulmonum  may  occur;  pallor,  a  waxy,  pasty  skin,  high  pulse  tension,  even 
in  this  form,  are  to  be  noted.  Headache,  neuralgias,  epigastric  pain,  disorders  of 
the  special  senses,  especially  amaurosis,  nausea,  and  vomiting  are  found,  but  not  so 
marked  nor  so  common  as  in  preeclamptic  toxemia.  Retinitis  allnnninurica  is  very 
serious,  and  may  leave  permanent  ])lindness.  Convulsions  occur,  but  in  less  than 
one-third  of  the  cases.  The  urinary  findings  are  similar  to  those  of  preeclamptic  tox- 
emic nephritis^albumin,  hyaline,  granular,  cellular  casts,  renal  epithelium,  white 
and  finally  red  blood-corpuscles.  Urea  is  diminished,  the  total  solids  reduced, 
the  daily  amount  of  urine  much  less  than  normal. 

Labor  has  a  noxious  influence  on  the  nephritis,  and  often  produces  alarming 
symptoms — oedema  pulmonum,  collapse,  which  may  simulate  pulmonary  or  cere- 
bral embolism,  apoplexy,  and  suppression  of  urine.     Anemia  is  badly  Ijorne  by

DISEASES   OF   THE    URINAUY    SYSTEM  497 

nephritics.  If  jiiicsthetics  aro  given,  and  if  the  lalnir  is  protracted  and  exhaus- 
ting, real  (Uiinagc  may  he  done  to  tiie  kidneys. 

The  puerperal  processes  do  not  exert  a  good  influence  either — sepsis  is  com- 
moner and  nephritics  do  not  bear  infection  well.  While  the  urine  usually  rapidly 
clears  up  after  delivery,  the  restitution  of  the  kidneys  is  never  complete,  pennanent 
structural  damage  having  been  wrought,  and  the  action  of  repeate<l  pregnancies  is 
so  bad  that  death  is  hastened. 

Chronic  intermit  it  ial  nephritis  is  more  frecjuent  than  the  parenchymatcjus,  and  is 
characterized  by  polyuria  of  low  specific  gravit}',  with  little  urea  and  small  amount 
of  albumin,  few  casts,  ami  these  usually  of  the  hyaline  variety.  It  is  accomi)anied 
by  high  arterial  tension  (200  to  210  nun.),  thickening  of  the  vessels,  and  hypertro- 
phy of  the  heart.  The  elYects  of  this  f(jrm  usually  a])pear  later  in  the  pregnancy, 
but  the  sj'mptoms  of  urinemia  already  mentioned  occur  with  almost  ecjual  fre- 
quency, and  especially  in  the  later  months,  the  distinctions  between  the  various 
forms  become  blurred.  Retinitis,  apoplexy,  and  heart  collapse  are  njore  fre(|uent 
with  cirrhotic  kidney,  and  c(jnvulsions  less  fre(|uent. 

All  forms  of  nephritis  have  a  very  bad  influence  on  the  j)regnancv,  abortion  and 
premature  labor  being  common  (00  per  cent.,  Ilofmeier);  Seitz  fcjund  that  only 
from  20  to  30  per  cent,  of  the  children  survived.  One  of  the  causes  of  habitual 
death  of  the  fetus  and  abortion  and  premature  labor  is  chronic  nephritis.  Labor  in 
nephritics  is  slow:  the  uterus  is  indolent;  tlie  edema  of  the  vulva  i)redisposes  to 
perineal  lacerations,  and  in  one  case  of  the  author's  the  edema  of  the  pelvic  struc- 
tures prevented  the  heail  from  engaging  in  the  pelvis.  Even  after  the  delivery, 
which  was  very  laborious,  the  cervix  could  not  be  drawn  down  to  the  vulva  as  usual, 
Ijecause  it  was  anchored  up  high  by  the  infiltrated  broad  ligaments.  Abru|itio 
placentie  is  not  infreciuent.  Pcjstpartum  hemorrhage  is  common  becau.se  of  atony 
of  the  uterus.  Involution  is  slower.  Many  of  the  children  are  bom  dead  and 
more  or  less  macerated.  The  death  of  the  fetus  is  caused  by — (1)  The  hemorrhages, 
the  white  infarcts,  and  tlie  sclerosis  of  the  blood-vess<'ls  of  the  placenta,  which  cut 
off  the  fetal  circulation  and  are  frequently  found  (SO  jier  cent.),  f^imjjson  and 
Fehling  called  attention  to  these  facts,  and  the  French  call  the  condition  "placenta 
albuminurique"  (Fig.  488).  (2)  By  the  frequent  abruption  of  the  placenta  in 
labor.  (3)  By  the  accumulation  of  toxins  in  the  blood  which  alter  the  villi,  making 
them  unfit  for  the  function  of  nourishing  the  child,  or  in  the  decidu:r,  making  their 
blood-vessels  brittle  and  thrombotic,  and  themselves  liable  to  sej)aration  (a  degen- 
erative endometritis);  in  the  first  instance  death  of  the  fetus  occurs;  in  the  latter, 
hemorrhages  into  and  separation  of  the  decidua  with  abortion  result.  (4)  The 
fetus  is  poisoned  by  the  toxins  wliich  ])ass  over  from  thi'  mother,  (o)  Edamjisia 
may  interrupt  the  jiregnancy. 

The  children  of  nejihritics  are  usually  puny  anil  pale;  they  thrive  jxtorly  at 
first,  and  nuiy  show  all)uminuria  with  ca.sts.  Infarcts  and  hemorrhages  may  so 
retluce  the  functionating  area  of  the  placenta  that  the  fetus  does  not  receive  enough 
food — it  starves  in  utero.     The  jilacenta  may  be  edematous. 

Didgnosis. — The  discovery  of  albumin  in  the  urine  at  one  of  the  routine  <>xam- 
inations  leads  at  once  to  a  minute  investigation  of  the  cause.  It  is  an  error  of  art 
to  be  surprised  into  making  a  urinalysis  by  the  symjitoms  of  nephritis.  The  author 
is  very  skeptical  about  the  so-called  physiologic  albuminuria.s— most  often  a  slum- 
bering disease  is  at  the  bottom.  Before  tleciding  that  the  kidneys  are  afTected  one 
must  eliminate  cystitis,  ureteritis,  and  congestive  ct»nditions.  It  is  usually  im- 
possible to  differentiate  the  various  forms  of  nej)hritis  during  gestation,  because  the 
urinary  and  clinical  pictun^s  are  blurred,  but  it  is  not  (>s.sential  for  treatment. 

Prognosis. — Both  mother  and  child  are  seriously  jeojiardized  by  chronic  neph- 
ritis, the  mortalities  b«'ing  about  30  and  70  per  cent,  respectively.  Care  mu.st  l»e 
exercised  in  promising  a  cure  by  the  induction  of  abortion  or  pn-mature  labor,  l)e-

cause  the  condition  may  not  be  the  simple  kithiey  of  pregnancy,  but  a  real  latent 
nephritis  which  has  been  awakened  into  activity.  The  main  dangers  of  nephritis 
are  edema  of  the  lungs,  hydropericardium,  hydropleura,  enormous  anasarca,  retin- 
itis, which  may  lead  to  permanent  ))lindncss,  apo])lexy,  eclampsia,  and  acute  heart 
collapse.     A  combination  \yith  heart  disease  is  very  fatal. 

Treatment. — Women  with  chronic  nephritis  should  not  marry,  and  if  married, 
should  not  conceive.  If  a  woman  had  eclampsia  or  symptoms  of  renal  inefficiency 
in  her  first  pregnancy,  a  second  sliould  not  be  allowed  until  tlu;  evidences  of  renal 
disease  have  remained  al:)sent  for  at  least  a  year.  Should  pregnancy  occur  with 
diseased  kidneys,  redoubled  watchfulness  is  required. 

(a)  Nephritis  is  Discovered  After  the  Twenty-eighth  Week. — While  a  cure  cannot 
be  effected  during  gestation,  most  authors  advise  that  the  patient  l^e  tided  along  to 
term  if  possible,  but  to  induce  premature  labor  in  the  presence  of  threatening  symp- 
toms. The  details  of  the  medical  treatment  have  been  fully  given  in  the  chapter 
on  Eclampsia,  to  which  the  reader  is  referred.  Here  the  imminence  of  convulsions 
or  coma  decides  the  question  of  the  induction  of  labor,  but  in  nephritis  other  dangers 
may  indicate  interference.  Retinitis  albuminurica  is  a  positive  indication  for  the 
immediate  termination  of  gestation.  Immense  anasarca  and  a  laboring  heart,  which 
do  not  respond  to  treatment,  also  are  good  reasons;  then  the  dangers  which  threaten 
the  child  must  be  considered — abruptio  placentae  and  hemorrhages  into  it,  though 
t  o  discover  these  accidents  in  time  to  save  the  infant  is  not  always  possible.  For 
this  reason,  and  because  our  knowledge  of  nephritis  is  so  uncertain  and  our  reliance 
on  treatment  so  insecure,  I  usually  interrupt  pregnancy  as  a  matter  of  principle 
when  the  child  has  fully  passed  the  period  of  viability.  The  exceptions,  of  course, 
are  those  cases  where  very  satisfactory  improvement  ensues  under  treatment. 
The  usual  methods  of  inducing  labor  are  employed,  but  in  critical  cases  vaginal 
cesarean  section  may  be  indicated. 

(5)  Nephritis  is  Discovered  Before  the  Child  is  Viable. — Some  authorities  (Schro- 
der, Fehling,  Billings,  Tyson,  Edwards,  Schauta,  and  others)  recommend  the  induc- 
tion of  abortion,  holding  that  the  injury  to  the  kidneys  which  is  inevitable  before 
the  child  becomes  via]3le,  and,  too,  the  poor  chances  of  the  fetus  in  any  case,  make 
the  continuance  of  the  pregnancy  precarious  and  useless.  With  these  opinions 
mine  agrees,  but  if  the  woman  is  near  the  period  of  viability,  I  try  to  tide  her  along 
a  few  weeks  to  give  the  child  a  better  chance  for  its  life.  Of  course,  the  gravida 
must  stay  in  bed  under  rigid  treatment,  and  a  careful  daily  urinalysis  must  be  made. 
In  the  early  months  the  pregnancy  is  interrupted  on  the  first  indication  of  trouble, 
and,  too,  if  the  disease  of  the  kidneys,  while  not  retrogressing,  remains  stationary 
under  treatment.  Experience  has  shown  that  these  cases  always  grow  worse  and 
require  interference  before  viability  of  the  child,  and  it  is,  therefore,  injudicious  to 
wait,  because  the  kidneys  ^vill  suffer  irreparable  damage  in  the  mean  time. 

During  labor  nephritics  require  special  care.  It  is  -svise  to  watch  the  heart 
action  closely  and  be  prepared  for  the  same  emergencies  that  occur  with  heart 
lesions.  It  may  be  necessary  to  puncture  the  swollen  labia  vulvae  (antiseptically, 
of  course)  to  allow  delivery.  In  the  puerperium  the  usual  treatment  is  kept  up. 
Nursing  is  to  be  permitted  only  if  the  puerpera  is  in  good  condition  and  the  renal 
symptoms  disappearing.      (See  Friinkl-Hochwart  and  von  Noorden,  Fellner.) 

Pyelitis  and  Ureteritis. — A  not  infrequent  complication  of  pregnancy  is  in- 
flammation of  the  kidney  pelvis  and  the  ureters.  Rayer,  in  1840,  first  descril^ed  the 
disease,  and  Reblaub,  in  1893,  reported  several  cases  at  the  Congress  of  the  French 
surgeons.  Bacteriuria  is  found  in  about  15  per  cent,  of  pregnant  women.  The 
ureters,  particularly  the  right,  have  been  found  dilated  and  filled  with  urine  in 
about  two-thirds  of  the  gravidas  coming  to  autopsy.  This  is  caused  by  torsion, 
stretching,  or  kinking  of  the  ureters,  due  to  the  enlargement  and  dislocation  of  the 
pelvic  organs,  but  not  to  compression,  since  the  specific  gravity  of  the  pregnant 


DISEL\SES    OF    TlIK    ritlNAKY    SVSTK.M  499 

uterus  is  about  equal  to  that  of  the  iiitcstiiial  mass.  'I'hc  pressure  in  the  i>elvis  of 
tiie  kidney  is  only  10  mm.  H^;,  so  that  shji;ht  eau.scs  may  stop  the  How  of  the  urine 
in  tiie  ureter.  Owinj;  to  the  stasis  of  tiie  urine  and  the  hacteriuria,  a  pyelo-ureteri- 
tis  is  easily  set  up,  but  infeetion  ean  reaeh  the  parts  also  throuKh  the  bhjod.  through 
the  lymi)h-stream  from  eontiguous  structures,  for  example,  the  appendix,  the  eolon, 
and  1)V  ascending  from  the  bladder.  The  bacterium  most  <jftcn  found  is  tin*  eolon 
bacillus, but  the  streptococcus, the  stapiiyl(jcoccus,the  Pn^teus  vul^jaris.  pneumococ- 
cus,  liacillus  typhosus,  B.  paratyphosus  (Williamson),  and,  frefjuently,  according 
to  Vineberg,  the  gonocoecus,  may  be  associated,  or  even  the  actual  cause.  Preg- 
nancy may  develop  the  disease,  or  may  aggravate  a  jjreexistent  inflammation  which 
may  have  starte(l  in  childhood  or  at  tiic  defloration  ( Wildbol/. ).  Two  varieties 
are  found  in  i)ractice — the  acute  and  the  subacute. 

In  the  acute  cases  there  are  chill,  fever,  pain  in  the  back  and  along  the  ureter, 
and  the  symptoms  of  cystitis — dysuria,  frequent  urination,  vesical  tenesmus,  etc. 
Rarely  all  symptoms  are  al)sent,  the  disease  being  accidentally  discovered  by 
urinalysis.  On  palpation  the  kidney  is  sometimes  enlarged  ami  always  tender;  on 
vaginal  examination  the  base  of  the  bladder  is  sensitive,  the  un'ter  usually  easily 
palpable,  thickened,  and  acutely  jxiinful  to  touch.  At  first  there  may  Ix-  sup- 
pression, but  soon  the  urine  is  increased  in  amount,  is  cloudy,  contains  at  first 
little,  later  nuicii,  pus,  albumin,  characteristic  epithelium,  and  swarms  with  bac- 
teria. If  the  kidney  structure  itself  is  involved. — and  tlu'se  cases  are  usually  mixed 
streptococcus  and  Bacterium  coli  infections, — the  general  symptoms  take  on  a 
septic  nature,  such  as  repeated  chills,  with  irregular  high  fever  and  evidences  of 
severe  illness,  while  locally  a  pyonephrosis  may  deveh^p.  One  or  both  ureters  may 
be  involved,  but  the  disease  is  more  frecjuently  right-sided.  Stone  in  the  kidney  or 
ureter  gives  the  same  sympt(jms  as  occur  outside  of  pregnancy. 

Suppression  (?f  urine  in  the  course  of  ureteropyelitis  may  be  either  renal  or 
ureteral,  in  the  former  case  due  to  infiaiumatory  congestion,  in  the  latter  to  block- 
ing of  the  ureter.  The  diagnosis  of  blocking  of  the  ureter  is  not  ea.sy.  Renal  colic, 
intermittent  i)olyuria  with  discharges  of  pus  and  relief  of  pain,  the  results  of  cathe- 
terization of  the  ureters,  access  of  fever  at  the  time  ])us  is  ab.sent  from  the  urine, 
— all  are  suggestive.  The  phenolsulphoi^hthalein  t«'st  is  more  useful  in  these 
surgical  renal  affections  than  in  nephritis. 

When  the  infection  is  subacute,  the  symjjtoms  are  milder;  frequent  urination 
and  evidences  of  cystitis  may  exist  for  several  weeks  before  the  jiain  in  the  ureter 
and  the  kidney  shows  the  ascending  involvement  of  the  latter.  In  both  ca.sj'sthe 
tendency  is  towartl  cure,  reciuiring  two  to  eight  weeks,  and  recovery  may  l>e  com- 
plete during  pregnancy  or  almost  certainly  after  delivery.  Recurrences  are  in- 
frecjuent.  One  observes  the  affection  most  freciuently  about  th<'  fifth  month  and 
again  near  term.  Renal  calculi  may  be  an  additional  comjilication.  In  the  puer- 
perium  acute  pyelitis  also  occurs,  and  may  give  rise  {o  suspicion  of  ])uerperal  in- 
fection, and  it  is  possil)le  that  the  infected  urine  flowing  over  the  genital  wounds 
may  cause  sepsis.  .\  jncloureteritis  which  apparently  healed  during  pregnancy 
may  ligiit  up  in  the  jiuerperiuni. 

Didfinofiis. — On  the  direct,  the  sym|)toms  enmnerated  plus  the  urin«'  findings 
will  usually  suffice.  I  have  fre(iuently  noted  the  jiresence  in  the  urine  of  swollen 
and  transparent  mononuclear  leukocytes,  the  nucleus  hanging  on  the  side  of  the 
clear  protojilasm.  In  the  ditTeri-ntial  diagnosis  appendicitis,  calculi,  and  i)ueriMr:iI 
infection  are  to  be  considered.

Treatment. — Acute  cases.  Rest  in  bed,  milk,  buttermilk,  and  water  diet; 
hexamethylenamin,  8  grains,  with  methylene-blue,  1  grain,  four  times  daily  until 
the  acute  symptoms  have  subsided,  then  bland  diet,  with  little  meat.  If  the  uro- 
tropin  should  cause  hematuria  or  disturb  the  stomach,  salol  may  be  substituted. 
For  the  subacute  cases  the  same  treatment  for  a  few  days,  then  more  freedom  and 
food.  The  knee-chest  position,  assumed  thrice  daily,  for  ten  minutes  each  time, 
and  the  elevated  Sims'  posture  (Fig.  557)  while  in  bed,  are  strong  adjuvants,  often 
actually  curative.  To  aid  posture  in  relieving  the  stagnation  of  the  urine  a  balloon 
pessary  may  })e  placed  in  the  vagina  to  lift  the  uterus  out  of  the  pelvis,  and  hot 
vaginal  douches  may  be  given.  Water  is  to  be  freely  administered  by  mouth,  per 
rectum,  and  hypodermically.  Ureteral  catheterization,  washing  out  the  pelvis  of 
the  kidney,  with  or  without  the  instillation  of  antiseptics,  has  l)een  so  succes.sful 
that  it  should  be  given  a  trial  before  radical  measures  are  instituted.     Israel,  Rov- 


DISEASES   OF   THE   URINARY   SYSTEM  501 

sing,  and  others  do  not  fully  approve  of  ureteral  catheterization.  X'accine  therapy 
had  Ix'ttcr  Ix'  postponed  until  after  delivery  unless  tiie  dise:i>e  proves  rebellious. 

It  is  almost  never  necessary  to  incise  the  kidneys  (pyonephrosi.s),  and  ran'ly 
needful  to  induce  hihor.  In  very  bad  cases  the  latter  may  be  done  iK'cause  recovery 
ensues  when  the  uterus  is  emptied.  A  .stone  in  the  ureteral  opening  may  sometimes 
be  seen  and  extracted  cystoscopically,  and  such  an  examination  should  always 
precede  any  operative  interference.  Pus  in  and  annmd  the  kidney  is  to  In*  treat<'d 
on  surgical  principles. 

Bacteriuria. — In  1895  the  author  found  a  pure  culture  of  Streptococcus  pyo- 
genes lonji;us  in  the  urine;  of  an  apparently  healthy  gravida  of  the  ninth  month. 
This  woman  had  an  operative  delivery,  and  developed  d(juble  phlegma-^^ia  alba 
dolens  on  the  tenth  day  of  the  puerperium.  Another  patient  sutTering  from  sepsis 
in  1S9()  showed  enormous  ma.sses  of  a  streptodiploccjccus  in  the  urine  and  in  the 
lochia.  Petruschki  in  1898  first  showed  that  living  typhoid  l)acilli  could  Ik-  found 
in  the  urine  months  after  convalescence.  Weicliselbaum  (cited  liy  Waltliard, 
loc.  cit.)  showed  the  streptococcus  in  the  urine  in  a  ca.se  of  sepsis. 

Alilberg  found  l)acteriuria  in  15  per  cent,  of  pregnant  women.  Murray  found 
the  Bacterium  coli  in  the  urine  in  44.5  per  cent,  of  g\'necologic  ca.ses  before,  and  in  93 
per  cent,  after,  operation.  It  would  be  interesting  to  discover  what  p<Tcentage  of 
eclamptics  and  nephritics  show  bacteria  in  the  urine.  Without  doubt  the  healthy 
kidney  can  and  does  excrete  bact<Tia,  and  it  is  more  than  probaljle  that  it  may  suffer 
injury  in  its  task.  Cloudiness  of  the  urine  is  often  due  to  l)acteria,  and  it  is  the 
author's  practice  to  give  such  ca.ses  urotropin  or  salol  until  the  condition  is  U't- 
tered.  It  is  not  unlikely  that  many  in.stances  of  puerperal  infection  will  1k'  trace- 
able to  infected  urine.  During  obstetric  oj)erations  one  should  not  allow  the  urine 
to  drip  over  the  field,  and  if  it  does,  the  parts  should  be  washed  with  antiseptic 
solutions. 

Cystitis  occurs  as  the  result  of  retroflexio  uteri  gravidi,  but  it  may  appear  alone, 
from  the  usual  causes,  aggravated  l)y  the  va.scularity  of  gestation.  Mihl  cystitis 
of  the  trigonum  is  common  and  jiroduces  fre(iuent  urination.  Diagnosis  and  treat- 
ment are  on  general  i)rinciples.  Hemorrhage  into  the  blad<ler  from  vesical  vari- 
cosities, hematuria  from  other  causes,  sometimes  apparently  none  other  than  gesta- 
tion, arc  observed  rarely.     (See  Venus,  Burnett,  Kolischer.  (Ipitz.  Cumston.)

DISEASES  OF  METABOLISM— DISEASES  OF  THE  EYE,  EAR,  NOSE, 

AND  THROAT 

DISEASES  OF  METABOLISM 

Diabetes. — Sugar  is  found  in  the  urine  in  about  5  per  cent,  of  gravidse,  but  it  is 
almost  always  milk-sugar  or  lactose,  and  when  proved  such,  requires  no  further 
attention.  True  glycosuria  is  very  rare,  unless  the  minute  traces  which  are  dis- 
coverable vnth  fine  reagents  are  considered,  and  when  it  is  found,  is  always  of  serious 
moment.  Alimentary  glycosuria  is  more  easily  produced  in  pregnancy  than  in  the 
normal  state,  a  point  which  must  be  considered  in  evaluating  the  discovery  of 
mellituria.  Transient  glycosuria,  sometimes  to  the  amount  of  2  or  even  3  per  cent., 
may  occur  in  the  latter  weeks  of  gestation,  accompanied  by  mild  sjinptoms  of 
diabetes.  Many  authors  hold  these  cases  as  of  no  real  significance,  since  recovery 
takes  place  after  delivery,  but  the  author  believes  that  they  are  really  the  first 
warnings  of  underlying  disease,  and  that  the  after-history  of  the  women  will  show 
the  same.  Habitual  death  of  the  child  in  pregnancy  and  after  labor  is  sometimes 
found  in  such  women,  and  in  two  of  my  cases  a  clear  hereditary  tendency  W' as  proved. 
True  diabetes  is  rare,  for  reasons  soon  to  be  given. 

Effects  of  Diabetes  on  Pregnancy. — Sterility  is  common,  Lecorche,  of  114  cases, 
finding  only  7  gestations.  This  is  due  to  atrophy  of  the  uterus  and  ovaries,  which 
also  explains  the  frequent  amenorrhea.  Abortion  and  premature  labor  occur  in  33 
per  cent,  of  the  pregnancies,  the  fetuses  usually  being  macerated.  The  children,  if 
the  pregnancy  goes  to  term,  often  die  shortly  after  birth,  the  total  mortality  being 
66  per  cent.  Sugar  is  sometimes  found  in  the  liquor  amnii,  and  if  germs  gain  access 
to  it  during  labor  (Bacterium  coli),  decomposition  sets  in  and  gas  forms^ — physome- 
tra.  The  infant  may  have  glycosuria.  Polyhydramnion  is  frequent,  and  over- 
growth of  the  child,  perhaps  edema,  has  rarely  been  noted.  Labor  in  diabetics  is 
not  very  different  from  the  normal.  Hemorrhage  is  not  a  prominent  symptom,  nor 
does  the  puerperium  show  anything  unusual.  Sepsis  is  not  more  freciuent — indeed, 
it  seems  as  if  they  are  a  little  more  resistant  to  infection. 

Effects  of  the  Pregnancy  on  the  Diabetes. — Without  doubt  pregnancy  has  a  bad 
effect  on  the  course  of  the  disease.  It  may  develop  a  latent  diabetes,  there  being 
cases  where  severe  symptoms  appeared  only  during  successive  pregnancies,  and 
others  where  the  disease  grew  progressively  worse  each  time.  Since  the  carbo- 
hydrate metabolism  of  the  liver  is  at  fault  in  diabetes  and  the  liver  is  overburdened 
during  gestation,  acute  hepatic  insufficiency  is  easily  explained.  The  acidosis  of 
hyperemesis  gravidarum — of  eclampsia- — is  on  the  same  basis.  I'nless  treatment 
is  instituted,  the  sugar  in  the  urine  increases,  the  malnutrition  becomes  marked, 
and  the  nervous  system,  which,  as  usual  in  pregnancy,  suffers  first  from  bad  in- 
fluences, begins  to  show  signs  of  intoxication.  Coma  occurs  in  30  per  cent,  of  the 
cases,  and  is  almost  always  fatal.  It  may  l)e  brought  on  by  a  very  slight  shock  in 
pregnancy,  but  more  often  during  and  just  after  labor.  Delivery  seems  to  have  even 
a  worse  effect  than  most  surgical  operations,  causing  collapse,  coma,  or  sudden 
death.  Bronchitis  has  been  often  noted  in  the  puerperium,  and  this  has  been  found 
to  eventuate  in  tuberculosis. 

Diagnosis  consists  in  determining  whether  the  case  is  one  of  true  diabetes, 
lactosuria,  alimentary  glycosuria,  or  transient  glycosuria  (alwavs  to  be  viewed  with 

502 


DISEASES    OF   METABOLISM  503 

suspicion).  A  real  diabetes  will  be  diagnosed  when  the  classic  symptoms  are 
present — grape-sugar  in  the  urine,  polyuria,  thirst,  and  malnutrition,  and  especi- 
ally if  the  urine  shows  large  amounts  of  sugar,  acetone,  diacetic  and  beta- 
oxybutyric  acids. 

Prognosis. — True  diabetes  has  a  very  bad  prognosis,  OfTergeld  finding  over  50 
per  cent,  mortality,  of  which  30  per  cent,  died  in  coma,  the  others  of  tuberculosis  or 
coma,  within  two  and  one-lialf  years.  The  ca.ses  of  glycosuria  (0.5  to  2  jxt  cent, 
sugar)  without  symptoms  of  malnutrition  or  of  markeil  acidosis  ofTcr  a  better  |)r(jg- 
nosis,  but  mu.st  be  watched.  Albuminuria  is  an  ominous  complication.  Of  the 
chiklren,  51  per  cent,  were  stillborn,  10  per  cent,  died  within  a  few  tlays  after  birth, 
and  5  per  cent,  more  before  six  months,  from  hydrocephalus  and  diabetes. 

Treatment. — In  all  ca.ses  the  usual  medical  treatment  is  to  be  employed.  Ali- 
mentary and  transient  glycosuria  need  no  other  consideration. 

(a)  Before  the  Child  is  Viable. — If  a  woman  comes  under  treatment  with  a 
history  of  diabetes,  and  the  examination  of  the  urine  in  the  first  months  shows  grape- 
sugar,  it  is  best  to  terminate  the  pregnancy  at  once.  The  attemi)t  to  carry  the 
patient  up  to  term  or  even  to  viability  of  the  child  is  too  perilou.s^either  the  shock 
of  tlelivery  brings  on  coma,  or  some  other  nervous  shock  iloes  it,  or  the  di.sea.se 
aggravates  dangerously,  and,  too  often,  the  child  dies  in  utero.  If  the  pregnancy  is 
near  viability  and  the  sj'inptoms  respond  to  medical  treatment,  one  may  try  to  tide 
the  woman  along  with  a  view  to  improving  the  child's  chances,  even  though  this 
hope  is  only  too  often  illusory — the  child  dies  either  before  or  after  delivery.  Klein- 
wiichter  says  we  should  not  consider  the  child  at  all. 

(6)  After  Viability  of  the  Child. — Since  some  cases  of  simple  glycosuria  occur 
at  this  time,  and  since  any  interference  or  even  natural  labor  may  evoke  a  terminal 
complication,  most  authorities  advise  waiting,  with  medical  treatment,  and  the 
induction  of  premature  labor  only  when  threatening  .symptoms  ari.se.  Williams — 
and  in  this  I  agree — advises  tlie  induction  of  premature  labor  in  all  cases  when  the 
sugar-content  of  the  urine  does  not  diminish  under  appropriate  treatment,  and  es- 
pecially if  ominous  conditions  are  found;  such  are  a  history  of  aggravation  in 
previous  pregnancies,  ])olyhydramnion,  acitlosis,  albuminuria,  acetonuria,  advanc- 
ing malnutrition  (determined  by  the  scale),  and  progressive  weakness.  Coma  in- 
dicates the  emptying  of  the  uterus,  but  the  child  is  almost  always  dead.  If  abor- 
tion or  premature  labor  is  to  be  induced,  no  anesthetic  is  to  l)e  employed,  and  the 
operation  is  done  with  the  least  possiblephysical  and  jisychic  shock.  If  an  anesthetic 
must  be  given,  use  ether.  Ergot  may  i)e  used  only  if  very  necessary.  Nursing  is 
not  to  be  permitted.     Further  child-bearing  is  prohibited  (Duncan,  Schade). 

Obesity. — Fat  women  are  often  ament)rrheic  and  sterile.  Amenorrheic  and 
sterile  women  are  often  fat.  Probably  the  cau.ses  of  the  two  conditions  are  similar, 
being  ])erha])s  due  to  anomalies  of  the  tluctless  glands.  Pregnancy  usually  cau.-*es 
deposition  of  fat  about  the  middle  of  the  boily,  and  many  women  put  on  fat  during 
and  alter  the  puerperium.  A  combination  of  obesity  with  infantile  pt^lvis  is  not 
rare.  Obesity,  when  extreme,  may  cause  abortion,  ami  in  some  instances  puny  chil- 
dren have  been  noted.  Edema  of  the  feet  anil  abdomen  is  often  noted.  Dys|>- 
nea  is  freciuently  a  troublesome  .symptom,  and  in  labor  the  heart  must  be  consi<l- 
eretl  like  that  of  myocarditis.  Rupture  of  the  uterus  is  favored  by  fatty  infiltration 
of  the  muscle-fibers.  Postpartum  hemorrhage  is  a  little  more  fnnpu'nt,  and 
manual  removal  of  the  placenta  oftener  necessar>',  l>ecau.se  the  thick  U'lly-wall 
prevents  a  good  ('red6  grasp  for  the  expression.  In  only  one  ca.<e  has  the  author 
noticed  that  the  fat  of  the  pelvis  obstructed  the  delivery,  and  this  was  at  the  outlet. 
Perineal  tears  are  more  common, and,  owingto  the  pre.sence  of  eczema  intertrigo  and 
the  locking  in  of  the  lochia,  the  union  of  the  wound  is  not  so  successful.  Operative 
procedures  are  very  lal^orious,  and  obesity  complicated  with  a  very  large  fetus  is  a 
formiilable  atYair.     In  general,  it  is  best  not  to  prescribe  active  antifat  treatment 


504      THE  PATHOLOGY  OF  PREGNANCY,  LABOR,  AND  THE  PUERPERIUM 

during  pregnancy,  but  where  the  obesity,  or  the  condition  underlying  it,  is  the  cause 
of  frequent  abortion  or  sterihty,  one  should  seek  to  establish  normal  conditions. 

Osteomalacia,  malacosteon,  mollities  ossiiim,  or  softening  of  the  bones,  is  a  disease 
which  is  verj'  rare  in  this  country,  being  found  principally  in  Italy,  the  Rhine  Valley,  certain 
places  along  the  Danube  River,  and  in  Flanders,  though  no  country  is  entirely  exempt.  In 
America  but  few  cases  are  reported,  mostly  importations — Hirst,  3;  Williams,  3;  and  the  author 
had  1  case,  an  Italian  woman  who  brought  her  illness  from  Naples.  In  pathology  the  disease 
consists  of  an  osteomyelitis  and  osteitis  progressing  from  the  marrow  along  the  Haversian  canals 
outward,  even  to  the  periosteum.  An  ab.sor]:)tion  of  the  lime-salts  of  the  bone  takes  place,  and 
later  the  spaces  are  filled  with  an  osteoid  substance  growing  in  from  the  marrow.  As  a  result  the 
bones  become  very  much  lighter  in  weight,  softer,  and  sometimes  so  flexible  that  a  pelvis  so 
affected  has  been  called  a  "rubber  pelvis."  The  calcium  and  phosphates  absorbed  from  the  bones 
are  excreted,  probably  through  the  urine  and  feces.  The  bones  themselves  are  very  vascular, 
reddish  yellow  or  brown,  and  in  advanced  cases  the  periosteum  remains  as  a  sac  filled  with  marrow 
and  fat.  If  a  cure  results,  bone  salts  are  again  deposited  in  the  osteoid  substance,  and  the  skeleton 
grows  very  hea\'3%  but  the  deformities  remain.  The  pelvis,  the  vertebra;,  the  ribs,  and  lastly 
the  long  bones  are  affected  in  order. 


Fig.  437. — Willard's  Case  of  Osteomalacia.     Porro  Cesarean  at  Five  Months. 

Osteomalacia  is  a  disease  of  adults,  but  a  case  occurring  in  a  girl  of  eleven  is  on  record.     A ; 
similar  disease  occurs  in  men  and  in  the  lower  animals.     It  bears  some  resemblance  to  rachitis. » 
Multiparae  are  much  oftener  affected  than  primipane,  and  frecjuent  child-bearing  seems  to  be ' 
an  active  factor.     It  occurs  most  often  in  women  of  the  lower  classes  of  poor  nutrition  and  unhy- 
gienic mode  of  life.    The  actual  cause  of  the  disease  is  unknown,  only  one  of  the  numerous  theories 
— that  of  Fehling — being  at  all  plausible.     Fehling  holds  that  the  abnormal  metabolism  of  the 
bones  is  due  to  a  trophoneurosis,  a  reflex  from  ovaries  in  a  state  of  hyperacti\dty,  and  the  almost 
uniform  success  of  castration  as  a  cure  gives  a  strong  basis  for  the  theory,     von  Velitz  found 
hyaline  degeneration  of  the  vessels  of  the  ovaries,  but  this  is  not  pathognomonic.     Since  we  know 
more  about  the  internal  secretions  of  the  ductless  glands,  and  since  the  ovaries  have  been  proved 
to  have  something  to  do  with  the  mitrition  and  growth  of  the  bones,  it  seems  more  probable  that 
the  cause  of  osteomalacia  may  be  foimd  by  search  along  these  lines.     Of  interest  are  the  experi- 
ments of  Sant-Agnese,  who  inserted  bits  of  rib  removed  from  osteomalacic  women  into  rats,  and 
found  bone  changes,  and  c-onstantly  the  Dij^lococcus  osteomalaciie  hominis  of  Morpurgo. 

Symptoms  usually  first  appear  during  pregnancy — pain  in  the  back  and  legs,  tenderness 
of  the  bones,  difficulty  in  locomotion,  a  waddling,  twisting  gait,  intention  tremor,  contracture  of 
the  adductors  of  the  thighs  and  of  the  levator  ani,  and,  since  the  weight  of  the  trunk  bears  hea\aly 
on  the  pelvis,  the  sacrum  and  innominates  are  (listorted,  the  inlet  narrowed,  and  the  stature  of 
the  woman  shortened.  Enrroacliincnt  f)f  the  bones  on  tlie  thoracic  cavity  causes  dyspnea  and 
cyanosis.  Softening  and  .separation  of  the  joints,  especially  thejx'lvic,  have  been  frequently  noted. 
After  delivery,  which  may  be  spontaneous,  recovery  takes  y)]ac(',,  but  since  these  women  are 
remarkably  fertile,  usually  a  new  pregnancy  soon  begins,  and  wit  li  t  he  recurrence  of  worse  symptoms.

bearing  on  the.se  two  conditions. 

Trciittnenl. — ^Phosphorus,  lime,  rod-liver  oil,  and  abundant  nourishment  are  always  to  be 
administered,  and  if  the  dis"a.'<e  is  rapirlly  pronressine,  the  ovaries  may  be  n-movcij.  Bf)ss  recom-

osleomalacic  .symptoms,  lime  and  i)hosphates  are  administ«'re<i  (Schnell). 


DISEASES  OF  THE  EYE,  EAR,  NOSE,  AND  THROAT 

The  Eye. — Even  the  ancients  know  that  sepsis  and  severe  hemorrhages  in  the 
pucrpciituii  could  produce  bUndness  and  stra})ismus,  and  a  connection  seemed  to 
Ik'  e.'<tal)li.^he(l  Ix'twccu  the  genitals  and  the  eyes  for  many  aHVctions  of  th<'  latter, 
hut  even  yet  the  exact  mode  of  interaction  i.^  obscure.  Many  theories  were  in- 
voked, as  reflex  action  from  the  genitalia,  retention  of  jjoi.-^ons  which  should  be 
eliminated  in  the  menstrual  blood  (Charrin  and  Roclie),  which  is  a  disinterment  of 
the  "purification"  theory  of  menstruation;  hysteria  and  neuroses,  tlemineraliza- 
tion  of  the  blood,  toxemia,  abnormal  or  insufficient  inteiTial  secretion  of  certain 
organs,  especially  the  ovaries.  It  is  ])robal)le  that  several  of  these  liypotheses  may 
explain  the  numerous  ocular  manifestations  which  seem  to  bear  relation  to  gesta- 
tion. 

During  pregnancy  excessive  jiigmentation  of  the  eyelids  is  sometimes  noted  in 
neurotic  women.  Tanner  s])eaks  of  a  chromidrosis.  Ulcer  of  the  cornea,  cho- 
roiditis, and  glaucoma  may  begin  or  l)e  aggravateil,  and  a  few  pregnant  women 
complain  of  scotomata  and  dyschromatopsia.  Thi.s  may  l)e  due  to  an  optic  neuritis, 
which  occurs  also  in  the  jiuerjierium,  may  be  a.s.sociated  with,  and  probably  is 
similar  to.  tho  iiolyneuritis  of  i)regnancv.  Since  atrophy  of  the  o\A\v  nerve  may 
result,  the  pregnancy  should  be  interrupted.  \\'eakness  of  accommodation  and 
muscular  asthenopia  are  not  very  rare,  and  may  require  temporary  treatment. 
Hemeralopia  has  sometimes  been  found  to  precede  the  amaurosis  of  toxemia. 
Retinal  hemorrhage  and  abruptio  retime  are  serious  comjilications,  usually  re(|uir- 
ing  interference.  Teillas  ol).<erve<l  four  gravida*  recover  completely  from  retinal 
hemorrhages. 

Preeclamptic  toxemia  and  renal  disease  sometimes  produce  an  acute  amauro- 
sis, already  referred  to.  which  usually  is  tran-sitory,  disapp«'aring  more  or  le.ss  com- 
pletely when  the  uterus  is  emptied.  It  may  occur  with  po.stparttun  eelamjisia 
also  or  indejM'ndently.  The  blindness  often  precedes  the  convulsions  or  coma  for 
several  days,  and  is  of  great  jirognostic  imi)t)rtance.  ( )i)hthalmoscopically.  nothing 
is  to  be  seen  on  the  retina.  It  lasts  two  to  six  days  after  consciousness  n-tums.  but 
may  leave  iinpaire<l  vision.  It  is  due.  according  to  Berger  and  I.cM'wy.  to  a  poi.son- 
ing  of  the  ganglia  and  ojjtic  nerves.  th(>  toxins  having  a  s|K'cial  .M-lectiv*-  aeti(»n  for 
them.  Such  selective  action  of  poi.sons  is  well  known-  for  example,  tetanus, 
strychnin.  This  theory  appeals  .strongly  to  the  atithor.  Pregnancy  .^^'t-ms  to  di.«<- 
pose  to  the  occurrence'  of  neuroretinitis.  with  a  tendency  to  hemorrhages  and  <'xu- 
dates.  Posey  and  Hirst  .believe  that  the  optic  netiritis  and  retinitis,  due  to  the 
toxemia  of  pregnancy,  mawmlicate  the  ba.-^al  trouble  lu'fore  changes  show  in  the  urine. 


506  THE    PATHOLOGY   OF   PREGXAXCY,    LABOR,    AND    THE    PUERPERIUM 

Acute  amblyopia  or  amaurosis  occurring  in  the  course  of  pregnancy  demands  im- 
mediate urinalysis,  and  if  all)umin  or  other  signs  of  renal  or  hepatic  insufficiency  are 
present,  the  induction  of  laljor.  Another  form  of  amljlyopia  and  amaurosis  may 
develop  in  the  course  of  renal  or  hepatic  disease  during  gestation — retinitis  albu- 
minurica.  This  is  easily  diagnosed  with  the  ophthalmoscope  by  the  hemorrhages 
and  the  white  spots  and  lines  which  show  the  degeneration  of  the  retinal  vessels. 
These  changes  may  long  j^recede  the  complaint  of  loss  of  vision.  Exophthalmos 
is  sometimes  associated  (Barker).  First  the  women  complain  of  specks  before  the 
eyes,  dimness  of  vision,  sometimes  hemeralopia,  colored  lights,  amblyopia,  and 
finally  of  complete  blindness.  Retinitis  albuminurica  may  occur  in  all  forms  of 
kidney  disease  during  pregnancy,  but  the  prognosis  is  somewhat  better  than  those 
cases  which  occur  outside  of  gestation.  It  is  more  frequent  in  the  chronic  forms  of 
disease,  and  it  always  indicates  the  immediate  emptying  of  the  uterus.  This  is  to 
save  the  sight  and  to  prevent  eclampsia  and  uremia.  Abruptio  retinae  may  com- 
plicate the  retinitis.  After  delivery  the  sight  returns,  but  usually  incompletely, 
though  a  few  cases  of  cure  are  on  record.  In  a  subsequent  pregnancy  the  condition 
usually  recurs,  but  even  though  it  may  not,  one  should  always  counsel  the  dis- 
continuance of  child-bearing.  Edema  of  the  lids,  of  the  bulbar  conjunctivae,  and 
even  of  the  retina  are  found  in  nephritis. 

During  labor  hemorrhages  in  the  conjunctivae  and  behind  the  bulb  have  been 
noted,  also  hysteric  amaurosis  and  xanthopsia. 

During  the  puerperium  all  the  conditions  mentioned  may  occur  or  be  carried 
over  from  pregnancy.  I  have  seen  one  case  of  hysteric  amaurosis  and  several  of 
blepharitis  marginalis,  of  hordeolum,  and  one  of  phlyctenular  conjunctivitis,  which 
three  are  generally  ascribed  to  the  influence  of  lactation.  Treatment  consists  of  the 
administration  of  lime,  phosphates,  and  general  roborants.  INIuscular  asthenopia 
has  been  noted,  and  I  have  seen  numerous  cases  of  headache  in  the  puerperium  from 
ej'e-strain.  The  women  look  down  at  the  baby  while  it  is  nursing,  and  the  eyes 
are  unaccustomed  to  such  prolonged  action.  Reading  in  bed  and  with  poor  light 
may  also  be  causative.  A  true  weakness  of  accommodation  occurs  also.  The  re- 
lation of  the  nasal  sinuses  to  the  eye  should  be  remembered. 

Optic  neuritis  may  be  associated  ^vith  ulnar  or  polyneuritis,  with  the  same  etiol- 
ogy. In  septic  cases  blindness  may  result  from  double  retinitis  septica,  from  pan- 
ophthalmitis, or  from  embolism  of  the  central  artery  of  the  retina. 

Severe  hemorrhage,  especially  if  associated  with,  other  diseases  which  weaken 
the  optic  nerve,  may  cause  temporary  or  permanent  blindness.  It  may  aggravate  a 
myopia  and  favors  optic  atrophy.  This  effect  may  come  on  at  once,  or  it  may  appear 
after  several  weeks.  It  is  due  to  anemia  of  the  retina  and  nerve  or  to  degenerative 
changes  in  them,  and  lasts  a  few  hours  in  the  first  instance,  and  may  be  more  or  less 
permanent  in  the  latter.  Choked  disc  with  l^lindness  has  been  observed  after  severe 
bleedings.  It  is  easily  seen  how  important  is  the  quick  restitution  of  the  blood  to  a 
normal  state,  and  Berger  and  Loewy  even  recommend  transfusion  ^^^.th  defibrinated 
blood,  in  addition  to  the  other  usual  remedies   (Runge,  Silex,  Shute). 

The  Ear. — Aurists  find  that  pregnancy  sometimes  unfavorably  affects  diseases 
of  the  ear.  ]\Iiddle-ear  infections  grow  worse,  chronic  thickenings  increase,  and 
deafness  becomes  more  marked,  all  of  which  is  especially  noticeable  in  repeated 
gestations.  Ringing  in  the  ears  may  be  a  symptom  of  toxemia,  and  even  deafness 
may  be  caused  by  an  auditory  neuritis  analogous  to  the  same  disease  of  the  optic 
nerve.  In  cases  of  rapidly  increasing  deafness  due  to  pregnancy,  the  induction 
of  premature  labor  is  to  be  debated  with  the  family  and  attending  aurist.  It 
is  possible  that  some  of  the  "fainting  spells"  to  which  pregnant  women  are  liable 
may  be  due  to  circulatory  disturbances  in  the  labyrinths  (Brickner,  Milligan). 

The  Nose.— A  general  hyperemia  of  the  nose  and  throat  has  been  noted  by 
rhinologists,  some  even  claiming  that  a  diagnosis  of  pregnancy  may  be  made  from 


TRAUMATISM  507 

the  nasal  findings.  Hofbauer  proved  clinically  and  microscopically  that  decided 
changes  exist.  The  intunu-scent  conditions  of  the  tiiri)inates  are  subject  to  aggrava- 
tion by  pregnancy.  Sinus  disease  is  not  ni(jre  conunon.  Its  treatment  is  the  same 
as  in  the  non-pregnant  conditi(jn— indeed,  all  sup|)urations  of  the  nose  and  thnjat 
must  l)e  curetl  before  labor,  i>ecau.se  the  focus  of  suppuration  may  lead  to  infection 
of  the  genitalia  or  the  breasts. 

Fliess  claims  that  the  anterior  ends  of  the  1o\v(t  and  middle  turbinates,  if 
disea.sed,  may  cause  dysmenorrhea,  and  if  cocainize(l  during  the  attack,  the  pain 
ceases,  and  that  cauterization  of  these  areas  will  cure.  My  e.xix'rience  with  this 
remedy  is  small  but  entirely  negative,  there  having  been  not  even  an  improvement 
which  might  have  been  a.scribed  to  suggestive  action.  He  als(j  claims  that  the  pains 
of  lal)(jr  and  hypcTemesis  gravidarum  may  be  favorably  influence<l  in  the  same  way. 
Epistaxis  has  l)een  noted  witii  some  fre(iuencv  in  pregnancy.  I'sually  an  ulcerated 
spot  is  not  found,  the  blood  coming  from  rupture  of  one  of  the  congested  capillaries. 
An  ulcer  may  be  cauterized,  even  though  Fliess  says  that  abortion  .sometimes  result.s 
from  such  action.     Vicarious  menstruation  through  the  nose  has  been  referred  to. 

Lingual  varicosities  are  sometimes  aggravated  l)y  pregnancy,  and  the  hyixTcmia 
may  leatl  to  some  hoarseness,  but  in  general  the  effects  of  gestation  are  not  promi- 
nent. Tuberculosis  of  the  larynx  is  most  unfavorably  influenced,  the  ulcerations 
becoming  deeper  and  spreading  rapidly,  and  freriuently  causing  edema  of  the  glottis. 
Pregnancy  seems  even  to  predispose  to  laryngeal  tulxTculosis.  Some  singers  claim 
that  it  injures  the  voice  to  sing  iluring  pregnancy,  and  there  seems  to  be  a  scientific 
reason  for  it.     It  is  denied  by  others. 

As  the  result  of  violent  labor  efforts  hemorrhages  may  take  place  in  the  mucous 
membrane  of  the  nose  and  throat,  as  well  as  the  ocular  conjunctiva',  while  after 
severe  blooil  loss  the  parts  are  very  anemic.  Women  who  shriek  continually  during 
prolonged  lal)or  may  show  on  examination  redness,  edema,  and  minute  blood  ex- 
travasations in  the  mucous  membrane  of  the  false  and  true  vocal  cortls  and  the 
posterior  wall  of  the  larynx.     After  delivery  the.se  changes  rapidly  clear  up. 


TRAUMATISM 

Pregnant  women  bear  the  effects  of  vioKnce  with  varying  resistance.  Wounds 
heal  with  their  usual  promptness,  and  the  old  notion  that  bones  unite  poorly  is  in- 
correct. Suggillations  are  ])erhai>s  a  little  more  extensive.  \'iolence  to  any  part 
of  the  l)ody,  l)Ut  particularly  to  the  genitals,  may  bring  on  abortion,  but  sometimes 
terril)le  shock  may  be  \\'ithout  effect  on  the  pregnancy,  as  in  Wahleyer's  case  of 
fracture  of  the  sacrum,  and  one  of  mine,  where  I  delivered  at  t(Tm  a  woman  on 
whom  an  inexperienced  surgeon  had  performed  curetage  at  three  months.  ( )p]>osed 
to  this  may  l)e  jilaced  the  well-authenticated  cases  of  a  slight  jar,  iis  from  misstej), 
causing  abortion.  OjxTations  are  to  i)e  ]MTfonned  on  any  part  of  the  Ixxly  if  the 
indication  is  real  and  urgent,  but  operations  of  convenience,  for  example,  simple 
hernia,  hemorrhoids,  etc.,  are  better  jiostponed.  Ovariotomy  has  often  l>een  done 
successfully  in  jiregnancy,  also  the  removal  of  fibroids  from  the  ut(TUs  itself.  The 
necessity  for  the  ovaries  seems  greatest  in  the  early  months.  Ix'cause  if  removeil 
later,  both  gestation  and  labor  may  be  natural.  Shock  and  sepsis  are  the  usual 
causes  of  the  abortion  when  such  occurs.  Oix'rations  on  the  labia  and  cervix  have 
been  done  without  disturbing  the  pregnancy,  and  even  exiiqiation  of  the  breast. 
Then,  again,  a  slight  oju'ration  on  some  distant  organ  or  extn-mity  will  bring  on  an 
abortion.  It  is,  tluTefore,  impossible  to  foretell  what  effect  a  given  interfcTence  will 
protluce.  It  seems  that  optTations  undertaken  at  the  time  the  woman  would  or- 
dinarily have  menstruated  are  more  likely  to  bring  on  pains.  \'esicovaginal  and 
rectovaginal  fistulas  have  been  cured  in  graviditate  and  the  local  changes  in  the 
tissues  seem  to  have  improveil,  rather  than  impaired,  the  process  of  wound  healing. 


508  THE   PATHOLOGY   OF    PREGNANCY,    LABOR,    AND    THE    PUERPERIUM 

Anesthetics  may  be  given  during  gestation,  but  there  is  clanger  of  asphyxiating  the 
infant.  Probably  death  of  the  child  causes  some  of  the  premature  labors  recorded 
after  operations.  Ether  is  the  safest,  and  the  administration  should  be  as  short  and 
as  light  as  possible.  A  dentist  informed  me  that  he  had  given  gas  to  pregnant  women 
hundreds  of  times  A\-ithout  injury,  but  in  one  of  my  cases  of  cesarean  section,  where 
gas-ether  narcosis  was  used,  the  child  was  mortally  asphyxiated.  Previously  it 
was  in  prime  condition,  and  the  actual  delivery  consumed  less  than  three  minutes. 
Operations  in  the  presence  of  pus,  especially  if  the  focus  of  infection  is  near  the  uterus, 
are  more  than  likely  to  l)e  followed  by  sepsis. 

Pregnant  and  puerperal  women  should  be  spared  mental  shocks,  if  at  all  pos- 
sible. Premature  labor  may  result,  even  fetal  death.  During  labor  a  shock  may 
suspend  uterine  action,  and  cases  are  recorded  where  collapse  and  death  resulted. 
A  shock  in  the  puerperium  has  been  ascribed  as  the  cause  of  diabetes,  acute  febrile 
reaction,  dementia,  convulsions,  hemorrhage,  and  death.  (See  "Sudden  Death.") 
A  shock,  too,  will  sometimes  alter  the  milk — either  dry  it  up  or  make  it  unfit,  even 
poisonous,  to  the  child.  How  these  changes  are  brought  about  is  still  a  subject  of 
conjecture.

CHAPTER  XLI 
LOCAL  DISEASES  ACCIDENTAL  TO  PREGNANCY 

DEFORMITIES  OF  THE  PARTURIENT  CANAL 

Embryologically,  the  uterus  and  vagina  are  formed  hy  the  fusion  of  the  two 
Miillerian  ducts,  tlio  union  takinp;  jjUice  from  hclow  upwtird.  Lack  of  fusion  at 
any  point  or  tiiroufj;iiout  tiie  lcnfi:th  of  the  two  canals  explains  almost  all  of  the  anom- 
alies that  are  observed,  and  rudimentary  development  of  one  duct  will  account  for 
the  l)alance.  All  degrees  of  lack  of  fusion  are  to  l>e  noted,  there  being  one  case  on 
record  where  two  complete,  but  single  and  distinct,  parturient  canals  with  tw(j  vulva* 
were  found, — uteruii  dulelphys, — antl  it  is  not  rare  to  find  the  fundus  uteri  indented 
in  the  middle, — the  "uterus  arcuatus,'' — which  is  just  the  indication  <jf  the  upix-r 
end  of  the  line  of  fusion  of  the  two  ducts.  In  some  animals  the  two  ducts  do  not 
fuse,  but  two  tul)ular  uteri  exist. 

Not  always  are  the  two  sides  of  the  uterus  and  vagina  equally  developed,  and 
we  observe  gradations  from  completeness  of  the  two  halves  to  almost  entire  absence 
of  one  Miillerian  duct.  The  rudimentary  side  lies  a.s  an  appendage  to  the  weil- 
develoi)ed  uterus,  but  since  its  canal,  four  times  out  of  five,  doe.s  not  communicate 
with  the  vagina,  trouble  frequently  ensues,  such  as  hematosalpinx,  hematometra, 
pregnancy  in  the  closed  horn,  etc.  (Ahlfeld.  Munde,  Santos). 

General  Considerations. — In  all  these  deformities  the  two  halves  are  usually 
not  synunctric:  one  or  the  other  horn  is  larger,  or  the  vaginas  are  unequal — some- 
times one  of  them  ends  blind  at  its  lower  end.  Coitus  is  rarely  interfered  with,  the 
larger  vagina  l)eing  used.  Menstruation  'comes  from  both  uteri  simultaneously, 
but  sometimes  only  from  one  at  a  time.  Pregnancy  may  occur  in  one  or  both  horns, 
twins  having  l^een  found  in  one  horn.  If  each  horn  contains  an  ovum,  the  two  chil- 
dren may  have  been  conceived  at  different  impregnations  and  ix'  delivered  at  in- 
tervals, thus  raising  the  suspicion  of  superfetation.  Pregnancy  is  ordinarily  un- 
disturbed, the  side  not  involved  growing  and  fonning  a  decidua  similarly  to  ectopic 
gestation.  The  decidua  of  the  emj^ty  side  may  be  cast  out,  while  the  i)regnancy 
continues  on  the  other  side.  The  course  of  the  ca.se  resembles  an  al)ortion,  and 
unless  the  duplicity  of  the  uterus  is  knoAMi,  the  accoucheur  may  attempt  to  curet, 
thus  unwittingly  destroying  a  living  ovum.  Usually  the  decitlua  comes  away  in 
the  jMieriM-rium  with  the  lochia.  Miiller  records  ca.ses  of  menstruation  from  the 
empty  horn  during  j)regnanc\'.  Abortion  may  occur,  and  it  may  l»e  diHicult  to  <'lean 
out  the  uterus,  especially  if  there  is  only  one  cervix.  It  is  doul)ly  important  to  in- 
sert the  finger  for  the  curetage.  In  septic  abortions  it  is  neces.sary  to  empty  both 
sides.  Labor  is  often  normal,  but  these  complications  have  lieen  observetl — weak 
pains  and  atony  in  the  third  stage,  with  posti)artum  lu'inorrhage;  the  non-preg- 
nant portion  of  the  uterus  may  prolaj)se  under  the  other,  and  act  like  a  tumor 
incarcerated  in  the  pelvis;  the  non-pregnant  cervix  may  1k'  forced  down  to  the 
vulva  with  the  head;  the  uterus  may  rupture,  Ix'cau.se  of  poor  nmsculature;  the 
septum  in  the  vagina  may  i)e  an  obstruction.  Septate  uteri  may  have  these 
complications:  breech  and  transverse  presentations:  weak  jiains:  atony  j>ost- 
partum;  rigidity  of  the  cervix;  placenta  on  the  septum  and  a«lherent:  and.  if  the 
st^ptum  is  in  the  cer\'ix,  obstruction  to  delivery.  In  one  of  my  ca.ses  the  child 
straddled  the  septum. 

Pregnancy  in  a  rudimentary  horn   resembles  ectopic  gestation  very  closely.

THE  PATHOLOGY  OF  PREGNANCY,  LABOR,  ANT)  THE  PUERPERIUM 


Mauriceau  and  Vassal,  in  16G9,  put  the  first  case  on  record,  and  now  over  100  have 
been  described.     If  the  accessory  horn  is  very  rudimentar}-,  it  may  be  closed  at

— One  finds  two  openings  into  two  separate 
vaginal  canals,  a  cervix  pointing  into  each,  and, 
if  the  OS  of  each  of  the  two  separate  uterine 
cavities  is  open,  a  finger  passed  into  them  will 
feel  a  septum  separating  the  two  ova.  In  my 
case,  from  which  the  diagram  is  drawn,  the 
woman  was  eight  months  pregnant,  with  a  child 
in  each  horn,  O.L.P.  and  O.D.T.,  and  a  deep 
furrow  could  be  felt  between  the  two  sides  of 
the  uterus.  One  horn  could  be  rotated  almost 
completely  around  the  other.  Fig.  439  shows 
the  appearance  of  the  vulva.  Another  prac- 
titioner conducted  the  labor.

both  ends,  making  pregnancy  impossible,  but  an  accumulation  of  menses  probable. 
Should  the  fertilized  ovum  be  inserted  in  the  small  horn,  there  is  no  hope  of  its 
finding  a  way  into  the  uterine  cavity  of  the  other,  because  the  connecting  bridge  of

tissue  is  usually  imperforate,  or  even  if  the  two  halves  are  l^roadly  apposed,  the 
two  cavities  usually  do  not  communicate,  or  the  opening  is  too  small.  Hyper- 
trophy of  the  muscle-wall  of  the  horn  may  occur  and  jjermit  the  ovum  to  grow  to

authors  ca.-^e  the  woman  was  pregnanf 
in  the  left  uterine  cavity  ami  alK»rte<i 
at  the  thin!  month.  If  the  fundus  al-o 
shows  si^ns  of  split  tint;,  it  is  calle<l  uterus

I'Urus  Suhst'ptufi  I'liicollis. — This  is

the  internal  os,  which  was  single.  The 
woman  had  ha«i  five  still-births,  brot-ch

pelvis.  In  the  sixth,  conducte*!  by  the 
author,  the  child  suffered  a  depres.setl

another  cjuse  the  l)reech  presented  in  each 
of  two  labors,  and  the  placenta  both  tinies 
was  adherent  to  the  septum.  This  form 
of  uterus  occurs  in  dogs,  camels,  sheep, 
etc.  If  there  are  indications  that  the

about  oct()i)ic  «r,.station  applies  to  this  subject.  Since  there  is  n(.  communication 
with  the  vagina,  the  spermatozoids  must  cross  over  from  the  oix-n  tul>e  to  the  dosed

side,  to  fertilize  the  ovum  from  the  ovary  on  the  side  of  the  pregnancy,  or  the  ovum 
from  the  open  side  wanders  over  to  the  closed  horn  before  or  after  fertilization. 

The  diagnosis  of  pregnancy  in  a  rudimentary  horn  is  occasionally  made,  but 
usually  the  a])domen  is  opened  for  rupture  of  a  supposed  extra-uterine  pregnancy. 


Septate  Vnginn. — Double  hymen  is  frequently  ob- 
served, but  gives  no  trouble,  either  in  diagnosis  or  treat- 
ment. A  septum  may  exist  at  any  point  of  the  vagina, 
or  even  throughout  its  whole  length.  In  these  cases 
the  lower  end  of  the  Miillerian  canal  failed  to  fuse,  but 
the  upper  portions  did,  forming  a  perfect  uterus. 
Occasionally  there  are  two  cervices.  The  septum  is 
usually  sagittal,  but  may  be  frontal  in  direction.

Uterus  Bicejrnis  Unolatere  Rudimentarius. — Of 
great  clinical  importance,  because  pregnancy  may  occiu* 
in  the  rudimentary  horn,  and  such  an  accident  is  worse 
than  ectopic  gestation,  with  which  it  is  usually  con- 
founded. 


Shows  the  accessory  horn  closed  at  both  ends,  and 
one  can  see  how  menstrual  blood  will  accumulate  in  it, 
causing  hematometra,  or,  if  the  vagina  is  also  partly 
formed,  hemelytrometra. 


Uterus  Unicornis. — Here  the  one  Miillerian  canal 
failed  to  develop.  It  is  normal  in  birds.  Such  a 
uterus  mav  bear  children  without  trouble.

514      THE  PATHOLOGY  OF  PREGNANCY,  LABOR,  AND  THE  PUERPERIUM 

tate  vagina  or  cervix  may  be  indicative  of  the  presence  of  some  anomaly,  and  pal- 
pation of  the  pedicle  (see  Fig.  451)  will  clinch  the  diagnosis.  If  the  fetus  dies, 
identical  changes  in  the  ovum  may  follow,  as  in  ectopic  ova,  and,  later,  owing  to 
adhesions,  shrinkage  of  the  sac,  etc.,  the  preoperative  diagnosis  is  usually  of  a 
fibroma  or  an  ovarian  cyst.  Contractions  occurring  in  the  sac  of  the  tumor  may 
give  the  clue  to  a  correct  diagnosis. 

Treatment  is  the  same  as  for  extra-uterine  pregnancy,  and  even  more  actively 
interfering  as  soon  as  the  diagnosis  is  made.  Rupture  of  the  sac  is  attended  with 
more  fatal  results^n  82  per  cent.,  according  to  Kehrer.  At  the  laparotomy  it  is 
best  to  remove  the  whole  sac,  if  possible;  if  not,  or  if  it  is  septic,  it  is  sewn  into  the 
abdominal  wall  and  drained  (Wells,  Engstrom), 

Diverticula  of  the  uterus  have  been  described,  and  in  one  case  the  placenta  was 
developed  in  an  accessory  uterine  cavity  connected  with  the  main  portion  by  a 
passage.  It  is  probable  that  these  are  cases  of  septate  uterus  with  incomplete  sep- 
tum. Incarceration  of  the  placenta  in  a  horn  of  the  uterus  is  not  rare,  and  some- 
times the  placenta  seems  to  occupy  a  compartment  of  its  own. 


THE  LOCAL  INFLAMMATIONS 

Vulvitis. — Owing  to  the  succulence  and  congestion  of  the  parts  and  to  the  pro- 
nounced pelvic  floor  projection  which  exposes  the  organ  more  to  injury,  vulvitis  is 
not  rare  in  gestation.  Lack  of  cleanliness,  obesity,  difficulty  in  keeping  the  parts 
clear  of  mucus  and  smegma,  which  accumulates,  purulent  discharges,  together  with 
the  openness  of  the  introitus,  invite  infection  and  eczema.  Mycotic  infection,  re- 
sembling thrush  of  the  mouth,  which  may  cover  the  whole  of  the  hyperemic  and 
moist  vulva,  and  pus  infections,  including  the  gonorrheal,  occur.  Vegetations  may 
be  seen  on  the  labia  minora  or  in  the  raphe,  and  they  may  occasionally  attain  enor- 
mous size.  They  are  sometimes  gonorrheal,  but  may  as  often  be  due  to  simple  un- 
cleanliness.  If  small,  the  usual  treatment  of  vaginitis  and  vulvitis  may  be  carried 
out.  If  large,  they  should  be  excised  and  the  base  touched  with  the  thermocautery 
to  stop  hemorrhage.  Even  if  the  signs  of  inflammation  fail,  the  pudendal  region 
becomes  the  habitat  of  the  Bacterium  coli,  the  staphylococcus  and  the  streptococcus, 
with  hosts  of  others.  For  mycosis  vulvae  painting  with  10  per  cent,  silver  nitrate 
or  tincture  of  iocUn  and  a  dusting-powder  of  boric  acid  will  be  curative;  the  other 
infections  are  treated  by  antiseptic  washes,  after  frequent  ablution  with  tincture  of 
green  soap. 

Bartholinitis  is  almost  always  due  to  the  gonococcus,  alone  or  in  association 
with  pus-germs.  Because  of  the  danger  of  puerperal  infection,  an  abscess  should 
be  cured  before  labor,  by  exsection,  if  possible.  Cysts  of  the  labia,  if  not  infected, 
are  best  left  until  after  the  puerperium  is  completed,  because  the  hemorrhage  from 
the  dilated  veins  is  troublesome. 

Vaginitis  is  not  so  common  as  vulvitis,  but  it  is  not  rare  to  find  a  reddened, 
granular,  thickened  mucosa  in  the  fornices — vaginitis  granulosa.  If  great  in  extent 
and  accompanied  by  profuse  purulent  discharge,  gonorrhea  is  to  be  searched  for. 
Winckel  described  a  rare  condition  known  as  colpohyperplasia  cystica  (Fig.  452), 
which  is  inflammatory,  perhaps  due  to  the  Bacillus  emphysematosus  vaginae  (Lin- 
denthal),  and  is  characterized  by  fine  vesicles  under  the  epithelium  of  the  mucosa, 
filled  with  fluid  or  gas — trimcthylamin  (Zweifel).  Vaginitis,  if  marked,  should  be 
treated  with  antiseptic  irrigations  during  pregnancy,  but  it  usually  disappears  only 
after  delivery.  The  reason  that  more  women  do  not  get  puerperal  infection  from 
the  septic  vagina  is  probably  because  the  local  immunities  are  developed.  Birth 
injuries,  however,  are  poorly  borne  in  these  cases  and  often  heal  unsatisfactorily. 

Gonorrhea. — Venereal  diseases  are  of  great  importance  in  obstetric  practice. 
Acute  gonorrhea  is  commoner  in  primiparaj,  being  conveyed  at  the  time  of  impregna-

tion.  Unlike  ordinary  ciiscs,  wlicrc  tlic  inHanunation  is  liiiiitcd  to  or  most  marked 
in  the  uretlira,  the  vulvar  glands,  and  the  cervix,  in  pregnancy,  favored  l>y  the 
succulence  of  the  tissues,  the  gonococcus  attacks  the  vaginal  and  vulvar  epithelium 
in  addition  to  those  mentioned.  Profuse  secretion  of  greenish-yellow  pus  results; 
the  vulva  is  red,  sometimes  covered  with  grayish  exudate,  sometimes  ulcerated,  or 
covered  with  gonorrheal,  pointed  condylomata;  the  vagina  is  thick  and  granular, 
like  a  nutmeg-grater,  and  bleeds  even  on  light  touch;  the  cervix  is  swollen,  vascular, 
eroded,  easily  vulnerable,  and  emits  a  foul  nmcopus  in  which  the  gonococci  are  most 
readily  found.  Chronic  infection  is  the  form  usually  met,  and  it  has  left  the  sur- 
faces, covered  by  s(|u:im()us  epithelium,  to  locali/c  in  the  urethra,  Skene's  tuliules, 
the  crypts  around  the  hymen,  the  Bartholiniau  ducts  and  glands,  and  the  cervix,

in  which  it  is  recognizable  by  the  usual  signs.  Acute  as  well  as  chronic  gonorrhea 
may  alYect  th(>  uterine  decidua  and  produce  abortion,  but,  as  a  rule,  the  gonorrheal 
endometritis  remains  latent  until  after  delivery.  Indeed,  many  women  having  a 
slight  mucopurulent  leukorrhea  are  delivered  without  the  accoucheur  i)eing  aware 
of  the  existence  of  an  infection  until  the  baby's  eyes  show  gonorrheal  ophthalmia. 
Through  the  traumatism  of  labor  the  gonococci  are  pressed  out  of  the  deep  cervical 
glantls,  and  by  virtue  of  the  open  ci-rvix  and  the  puerperal  process's,  unlimited  op- 
portunities are  afforded  them  for  further  virulent  develoiMuent.  As  a  n'sult,  gonor- 
rheal I'ndometritis,  salpingitis,  ovaritis,  and  pelvic  peritonitis  are  set  up.  refert^nce

associated  streptococci  and  staphylococci,  while  chronic  gonorrhea  causes  the  "late

fevers," — on  the  tenth  to  the  thirtieth  day, — an  ascending  inflammation  which  re- 
sults in  pus-tubes  or  adhesive  obhterating  peritonitis,  leaving  permanent  sterility 
and  gynecologic  invalidism.  Acute  gonorrhea  in  gestation  can  cause  rheumatism, 
with  disorganization  of  the  joints,  wrist,  knee,  hip,  etc.,  or  even  endocarditis  and 
general  septicemia  (q.  v.). 

Diagnosis. — In  maternities,  because  of  the  danger  of  carrying  infection  from 
one  patient  to  another,  it  is  highly  important  to  detect  the  first  case  of  gonorrhea, 
but,  unless  it  is  in  the  florid  stage,  this  is  almost  impossible.  Repeated  bacterio- 
logic  examination  of  the  secretions  is  often  required  for  the  detection  of  the 
gonococcus — one  negative  result  does  not  exclude  it.  The  history  is  valuable.  An 
obstinately  inflamed  single  joint  is  strongly  suggestive.  Ophthalmia  in  the  infant 
does  not  prove  the  existence  of  gonorrhea  in  the  mother  unless  the  gonococcus  be 
found  in  the  pus  and  other  sources  of  infection  of  the  child's  eyes  be  eliminated. 

Treatment  must  always  be  instituted  during  pregnane}",  but,  owing  to  the 
tendency  to  abortion,  gentle  means  are  adopted.  Vaginal  irrigation  morning  and 
evening  with  potassium  permanganate,  1 :  3000,  zinc  permanganate,  1 :  4000,  1  per 
cent,  ichthyol;  painting  the  vagina  with  5  per  cent,  silver  nitrate;  light  packing 
with  2  per  cent,  protargol  gauze,  removed  after  twenty-four  hours — will  usually 
quickly  reduce  the  disease  to  its  chronic  state.  Should  abortion  occur,  curetage 
is  not  to  be  undertaken  if  it  is  at  all  avoidable. 

During  labor  in  cases  of  known  gonorrhea  the  vagina  should  be  douched  every 
four  hours  with  a  weak  antiseptic  solution,  for  example,  1  per  cent,  lysol,  vaginal 
explorations  and  operations  limited  to  an  irreducible  minimum,  the  bag  of  waters 
saved,  if  possible,  until  the  child's  head  is  fully  born,  and  every  precaution  taken  to 
prevent  the  entrance  of  vaginal  mucus  into  the  conjunctival  sacs.  During  the 
puerperium  no  douches  may  be  given,  and  the  woman  should  be  kept  in  bed  fully 
eighteen  days — Bumm  says  five  to  six  weeks, — that  is,  until  the  involution  of  the 
uterus  is  complete, — this  to  prevent  the  ascension  of  the  infection  through  the 
uterus  to  the  tubes. 

Erosions  and  hypertrophy  of  the  cervix  are  not  infrequent,  and  since  the  soft- 
ened vascular  structure  bleeds  readily,  the  flowing  may  give  rise  to  the  suspicion  of 
abortion.  The  author  has  twice  seen  a  nodular  hypertrophy  of  the  cervix  with  ec- 
tropion and  cystic  degeneration  of  the  glands,  which  to  the  touch  resembled  can- 
cer, but  which  subsided  almost  entirely  after  delivery.  Erosions  during  pregnancy 
are  treated  by  irrigation  with  1  :  3000  potassium  permanganate  and  application 
of  10  per  cent,  silver  nitrate  to  the  patches  thrice  weekly.  Rest  in  bed  aids  the 
treatment  and  prevents  hemorrhage. 

Endometritis  Deciduae. — Acute  endometritis  frequently  accompanies  the  in- 
fectious diseases,  scarlet  fever,  typhoid,  cholera,  etc.  It  may  occur  as  the  result  of 
attempts  at  criminal  or  even  therapeutic  abortion.  In  one  of  my  cases  it  was  evi- 
dently due  to  external  infection  through  a  very  patulous  cervix,  perhaps  by  coitus. 
Gonorrhea  may  cause  it,  there  sometimes  being  tiny  abscesses  containing  gonococci 
in  the  decidua.  Abortion  is  probably  often  the  result  of  gonorrhea,  acute  and 
chronic.  Pus  may  accumulate  in  the  decidua  and  be  expelled  during  labor.  In 
two  of  my  cases  a  discharge  of  pus  from  the  uterus  followed  the  child,  no  complica- 
tion resulting. 

Chronic  endometritis  is  not  so  common  as  was  formerly  thought.  Hitschmann 
and  Adler  have  conclusively  shown  that  many  of  the  cases  of  so-called  glandular 
hjq^ertrophic  and  hyjoerplastic  endometritis  are  only  the  normal  menstrual  changes 
of  the  uterus.  Interstitial  endometritis  may  be  accompanied  by  a  hyperplasia  of 
the  glands,  but  unless  the  ''exudate  cells,"  especially  the  ''plasma"  cells,  arc  found, 
one  may  not  diagnose  endometritis.  Chronic  endometritis  is  most  often  the  result 
of  gonorrhea,  next  of  abortion,  then  of  displacements  and  lacerations  of  the  uterus. 
These  last  predispose  to  infection  of  the  uterine  mucosa,  and  Albert  proves  that 


LOCAL    DISEASES    ACCIDENTAL   TO    PREGNANCY 


517 


I'ol\  pfjid  hi'iuorrliugic  d<-ci(iuu 


there  is  a  latent  microbic  endometritis.  Irregular  li\inK,  congestions  during  men- 
struation, sexual  excess,  abnormal  sexual  practices,  traumatism  and  infection  at 
childbirtii,  retention  of  pieces  of  membrane,  but  especially  gonorrhea  and  aborticjn, 
cause  endometritis.  Tiie  chi.ssifieations  (jf  the  various  forms  arc  not  fully  satis- 
factory, even  to  the  gynecologists. 

During  pregnancy  the  pathologic  study  of  the  uterine  mucosa  is  doubly  difh- 
cult,  and  without  doubt  needs  reinvestigation  ^v^th  modern  methods.  Mo.st  authors 
distinguish  two  main  condition.s — endometritis  dccidua'  intcrstitialis  and  glandularis. 
The  intiannuation  is  usually-  present  before  conception,  but  n»ay  arise  during  preg- 
nancy, for  example,  from  a  syi)hilitic  ovum  or  from  gonorrhea.  Fig.  4')'.i  shows  a 
piece  of  decidua  vera  exjx'lled  in  an  abortion  at  ten  weeks.  It  is  thickened,  infil- 
trated with  round-cells,  degenerated  in  places,  strewn  with  minute  hemorrhages, 
and  shows  a  lumpy,  uneven, 
polypoid  surface.  \'irchow 
first  descriijed  it  as  endo- 
metritis deciduae  tuberosa 
or  polyposa,  or  both.  The 
glands  may  hyi)ertropliy 
also,  while  sometimes  atro- 
phic areas  are  found.  Syph- 
ilis may  occasionalh'  cause; 
such  changes. 

If  the  glands  are  af- 
fected, eitlier  by  hypertro- 
phy or  by  infianmiatory  hy- 
peremia, a  profuse  secretion 
results,  which  is  yellowish, 
serous,  slightly  mucous  or 
l)loody.  Sciiroder  called 
this  endometritis  decidual 
catarrhalis,  which  may 
give  the  clinical  course 
of  hytlrorrha>a  gravidarum. 
Should  the  mouths  of  the 
glands  be  occluded,  cysts 
containing  a  milky  fluid 
form  in  them — the  endo- 
metritis deciduiP  cystica  of 
Breus.  It  is  possible  that 
many  of  the  specimens 
called  by  the  older  writers 

decidua  with  "uterine  milk"  were  of  this  nature.  Endometritis  decidua' is  of  great 
clinical  importance.  It  causes  relative  sterility,  frecjuent  al)ortion,  and,  since  abor- 
tion often  leaves  endometritis,  a  vicious  circle  is  established — almormal  insertion  of 
the  ovum  (for  example,  jilacenta  prirvia),  abnormal  formation  as  to  shajx',  size, 
and  thickness  of  the  placenta,  infarcts,  retarded  developm«'nt  of  the  fetus.  al»ruptio 
placenta^,  and  thickening  and  retention  of  the  decidua.  During  pregnancy  one 
may  find  pain  in  the  uterus;  aggravation  of  the  sympathetic  disturbances,  esj^e- 
cially  hvperemesis ;  painful  uterine  contractions,  sometimes  called  "rheumati.sm 
of  the  uterus."  particularly  at  or  near  term:  local  temlerness.  and,  in  the  more 
acute  cases,  slight  fever,  malaise,  and  bloody  discharge,  which  arouses  a  suspicion  of 
abortion.  Much  dejiends  on  the  location  of  the  (liseas*>  and  the  extent  and  time  of 
its  occurrence.  If  the  decidua  serotina  is  involved,  early  death  of  the  fetus  and 
abortion  occur,  but  if  the  affection  is  mild.  i)n>gnancy  may  go  to  term,  and  one  will

518  THE    PATHOLOGY   OF    PREGNANCY,    LABOR,    AND    THE    PUERPERIUM 

note  only  anomalies  in  the  mechanism  of  placental  separation,  perhaps  placenta 
accreta.  The  earUer  the  disease  manifests  itself,  and  the  greater  its  extent,  the 
more  the  likelihood  of  abortion.  The  ovum  may  be  transformed  into  a  bloody  or 
fleshy  mole. 

Chronic  endometritis  affects  the  course  of  labor.  Since  usually  the  muscle  of 
the  uterus  is  involved,  weak  or  painful  pains  are  noted.  Premature  rupture  of  the 
membranes,  hemorrhages  into  the  decidua,  sometimes  at  the  placental  site,  with 
abruptio  placentae,  abnormalities  in  the  mechanism  of  the  third  stage,  atonia  uteri, 
from  myometritis,  retention  of  bits  of  placenta  or  membrane — all  these  may  require 
obstetric  interference.  Pieces  of  thick,  hard,  cheesy  decidua  may  remain  in  the 
uterus  after  the  placental  delivery  and  keep  up  a  prolonged,  even  dangerous,  oozing, 
requiring  manual  removal,  the  same  being  true  of  the  firm  blood-clots  which 
usually  surround  them.  If  these  foreign  matters  are  allowed  to  come  away  in  the 
puerperium,  they  cause  profuse,  prolonged,  bloody,  sometimes  fetid,  lochia,  occa- 
sionalh'  slight  fever,  and  always  delayed  involution. 

Evidences  of  endometritis  on  the  placenta  are :  Thickened  serotina,  which  may 
be  quite  opaque  and  ragged  in  places;  vascularization  of  the  margin  of  the  closing 
plate  of  Winkler,  which  may  extend  some  distance  under  the  membranes.  One 
may  see  arteries  and  veins  running  in  the  thick  decidua  vera  for  two  to  four  inches. 

The  maternal  surface  may  be  rough,  sometimes  hard,  and  there  are  numerous 
white  infarcts.  The  contour  of  the  placenta  may  be  irregular,  as  if  it  grew  easier  in 
one  direction  than  another;  there  is  a  tendency  to  the  formation  of  placenta  suc- 
centuriata,  and  placentula  succenturiata,  also  velamentous  insertion  of  the  cord. 
When  the  serotina,  through  chronic  inflammation,  or  because  of  lost  tissue  through 
previous  operations  or  disease,  cannot  react  with  sufficient  decidua,  the  villi  bore 
into  the  uterine  wall  and  the  placenta  is  adherent  to  the  musculature — placenta 
accreta.     (See  Postpartum  Hemorrhage.) 

Diagnosis. — The  diagnosis  may  be  suspected  during  pregnancy,  but  even  when 
the  symptoms,  as  given,  are  present,  a  certain  diagnosis  may  be  made  only  post- 
partum. If  the  condition  is  suspected,  appropriate  treatment  must  be  instituted 
for  the  prevention  of  the  evil  effects,  for  example,  placenta  prsevia,  premature  de- 
tachment of  placenta,  postpartum  hemorrhage,  premature  labor. 

Treatment. — Prophylactically,  much  can  be  done  to  prevent  endometritis  in  the 
early  cure  of  gonorrhea,  the  proper  care  of  abortion,  the  prevention  of  sepsis,  etc. 
Repeated  abortions  due  to  endometritis  maj^  sometimes  be  prevented  by  curetage, 
Bier's  suction  treatment,  etc.,  not  omitting  general  hygienic  measures.  During 
pregnancy  no  treatment  vnW  reach  the  diseased  part  unless  the  latter  be  syphilitic, 
and  here  the  appropriate  drugs  are  to  be  exhibited.  It  is  my  custom  to  give  all 
such  patients,  whether  syphilitic  or  not,  tonic  doses  of  mercury — ^-q  grain  of  corro- 
sive sublimate  in  tablet  three  times  daily.  If  pallor  and  general  asthenia  are 
present,  minute  doses  of  arsenic  and  iron  are  added.     Lomer  uses  potassium  iodid. 

Hydrorrhoea  Gravidarum. — A  periodic,  or  at  least  intermittent,  discharge  of 
clear,  yellowish,  or  sometimes  bloody  fluid  from  the  uterus  has  been  given  this 
name,  and  the  cause  is  almost  always  endometritis  deciduae  catarrhalis,  but  similar 
fluids  may  issue  from  the  uterus — first,  from  the  space  between  the  chorion  and 
amnion,  and,  second,  from  the  amniotic  cavity  itself,  that  is,  liquor  amnii  may 
escape.  In  typical  hydrorrhea  the  catarrhal  secretion  accunmlates  between  the 
vera  and  reflexa,  and  periodically  breaks  through  the  mucous  plug  which  fills  the 
cervix,  or  there  may  be  a  continuous  dribbling.  As  much  as  a  pint  maj^,  but  rarely, 
accumulate,  and  the  expulsion  of  such  an  amount  often  provokes  al)ortion  or  pre- 
mature labor.  The  disease  is  most  common  from  the  third  to  the  sixth  month,  but 
may  begin  or  continue  in  the  last  trimester.  The  pathology  is  not  fully  understood, 
except  that  an  endometritis  deciduae  is  usually  back  of  it.  It  occurs  in  anemic  and 
sickly  women,  especially  multiparae,  and  may,  if  slight,  be  overlooked. 


LOCAL   DISEASES    ACCIDENTAL   TO    PREGNAN'CY  519 

In  the  differential  diagnosis  rupture  of  the  hag  of  waters,  rupture  of  the  chorion, 
and  the  escape  of  subchorionic  fluid  and  hydrorrhea  are  to  be  considered.  The 
latter  two  cannot  be  distinguished  from  each  other,  but  Hquor  ainnii  can  often  be 
recognized  by  the  floccuH  of  vernix  cascosa,  if  kite  in  j)regnancy,  In-  the  lanugcj  liairs, 
and  sometimes  by  meconium.  Usually  it  is  impossible  t(^  make  the  diagnosis,  and 
in  all  cases  the  patient  is  treated  as  if  she  were  tlireatened  with  abortion. 

Formerly  it  was  held  that  if  the  ovular  sac  opened  and  the  liquor  amnii  drained 
away,  the  uterus  would  inevitably  empty  itself  within  a  short  period.  For  the 
vast  majority  of  ca.ses  this  is  true,  i)ut  sometimes  the  membranes,  after  rupture, 
shrink  up,  leaving  the  fetus  in  the  uterus,  l)ut  outside  of  the  ch<jrion.  Development 
of  the  child  is  nmch  hindered;  it  is  puny,  shrunken,  with  many  of  its  joints  anky- 
lotic,  and  showing  decubitus  over  bony  prominences.  In  adilition  to  this  form,  or 
graviditas  exochorialis,  another  variety  exists:  the  amnion  breaks,  but  th<*  chorion 
does  not,  and  the  shrunken  anmion  is  found  hanging  around  the  insertion  of  the  cord, 
but  the  chorion  is  intact — graviditas  examnialis. 

Endometritis  Syphilitica. — This  was  considered  under  Syphilis  (p.  483). 

Bacterial  Endometritis. — Gonorrheal  endometritis  has  already  been  mentioned, 
as  also  have  the  acute  processes  which  complicate  the  infectious  diseases.  Tul>er- 
cular  endometritis  may  occur  in  consumptives  and  in  miliary  tuberculosis.  In 
one  of  my  cases  a  tubercular  peritonitis  developed  acutely,  after  a  physician,  a 
sufferer  from  phthisis,  had  cureted  the  patient  without  sterilizing  his  instruments. 
Streptococci,  staphylococci,  and  Bacterium  coli  commune  (author)  have  Ix'en 
demonstrated  in  the  uterine  decitlua,  and,  in  addition,  (jther  unidentified  kinds. 
It  is  generally  held  that  while  the  vagina  may  harbor  pathogenic  bacteria,  they  live 
a  saprophytic  existence  there  and  do  not  wander  up  into  the  uterus.  A  few  authors 
believe  that,  under  favorable  circumstances,  such  a  transference  of  infection  may 
occur,  and  to  me  this  appears  very  probable.  Clinical  experience  points  to  it — 
for  example: 

Mrs.  W.,  aged  thirty-six,  quartipara,  four  months  prognant,  with  largo,  patulous  os,  sickons 
with  fever,  chills,  and  general  evidences  of  serious  disetise,  but  with  the  single  local  finding,  a  slight 
fetid  vaginal  discharge.  Attempts  at  criminal  abortion  abs<jlutely  excluded:  patient  desired  this 
child,  haWng  arranged  the  time  of  coitus.  Curetage  showeii  the  decidua  in  lower  portion  of  the 
uterus,  gray,  discolored,  and  soft .     After  operation,  chill  and  sharp  fever,  which  subside*!  gradually. 

^Irs.  C,  nmltipara  at  ti-rm.  On  complete  dilatation  of  the  cervix  the  niembrant-s  were 
ruptured  and  a  quart  of  unbearably  fetid,  thin,  meconium-stained,  gray-green  liquor  amnii  escaped. 
Deliverj'  normal;  puerperium  normal;  child  sur\'ived.  In  another  similar  case  the  child  suffered 
from  fever  and  severe  icterus  for  weeks. 

While  in  the  latter  instances  a  hematogenic  infection  of  the  liquor  amnii  may 
be  assumed,  in  the  first  one  the  bacteria  were  surely  introduced  from  the  cervix. 
It  is  certain  that  germs  can  permeate  the  membranes,  both  from  the  cerv-ix  and  from 
the  uterine  wall,  as  in  atlherent  ai)pentliceal  abscesses. 

Under  this  caption  should  l)e  briefly  mentioned  the /<rrr  of  pregnancy.  No  one 
believes  that  the  processes  of  pregnancy  are  ever  normally  attendetl  by  fever.  8eitz 
collected  numerous  cases  which  tend  to  show  that  a  bacterial  endometritis  can  cause 
fever  during  pregnancy,  subsiding  when  the  uterus  is  emptied.  Uterine  pain, 
tenderness,  even  local  peritonitic  symj)toms  were  present  in  a  few  of  the  cases; 
repeated  abortiim  with  bacteria  in  th»'  decidua;  eclampsia.  hy]XTemesis,  in  others. 
Coitus  carries  feces  and  other  contamination  into  the  vagina,  and  it  is  more  than 
probable  that  infection  of  the  ovum  frequently  thus  takes  place,  \>ith  consecutive 
abortion,  which  may  or  may  not  be  followed  by  g(Mieral  s<>psis.  If  Allx>rt  is  correct, 
that  a  microl)ic  endometritis  can  cause  eclampsia,  it  is  now  easy  to  explain  why 
eclamj^tics  are  so  prone  to  puerperal  infection  in  spit«'  of  most  rigorotis  asej>sis  and 
antisepsis.  Evidently,  here  is  a  fertile  and  unexi)lored  Held,  l)ut  this  much  is  to  l>e 
said — a  most  thorough  and  painstaking  general  examination  nmst  be  made,  and  a 


520      THE  PATHOLOGY  OF  PREGNANCY,  LABOR,  AND  THE  PUERPERIUM 

diagnosis  of  bacterial  endometritis  may  l)e  reached  onl}^  by  exclusion.  The  rela- 
tion of  such  infections  to  puerperal  fever  will  be  taken  up  later. 

Salpingitis  causes  sterility  because  it  is  almost  always  bilateral  and  occlusive. 
Chronic  tubal  inflammation  may  heal,  but  the  folds  of  the  mucosa  have  usually 
become  glued  together,  and  this  is  a  frequent  cause  of  ectopic  gestation.  Double 
pus-tubes,  of  course,  preclude  pregnancy,  but  sometimes  a  pus-tube  forms  after 
conception  has  occurred,  the  woman  having  been  infected  and  impregnated  at  the 
same  time.  In  rare  cases  a  tube  adherent  to  a  gangrenous  appendix  may  become 
infected.  Acute  salpingitis  is  a  very  serious  complication  of  gestation,  and  without 
doubt  is  the  hidden  cause  of  numerous  cases  of  sepsis  intrapartum  and  postpartum. 
During  gestation  the  diagnosis  is  almost  impossible;  a  peritonitis  will  be  assumed, 
and  if  the  symptoms  are  urgent,  laparotomy  will  have  to  be  performed.  During 
pregnancy  a  departure  should  be  made  from  the  method  of  treatment  of  pyosalpinx. 
Labor  will  almost  certainly  rupture  the  abscesses,  and  it  is,  therefore,  best  to  re- 
move the  sacs.  It  is  a  question  whether  it  is  advisable  to  wait  for  the  contents  to 
become  sterile.  If  at  operation  there  is  reason  to  believe  that  the  streptococcus  is 
associated  with  the  gonococcus,  it  may  be  wisest  to  extirpate  the  uterus  at  the  same 
time  that  the  tubes  are  removed,  l)ut  the  prognosis  is  bad  in  such  cases. 

Peritonitis  in  pregnancy  arises  from  appendicitis  or  salpingitis,  rupture  of  the 
infected  bladder  in  uterine  incarceration,  from  necrosing  fibroids,  infected  ectopic 
gestation-sacs,  twisted  ovarian  tumors,  and  after  attempts  at  criminal  abortion. 
In  many  autopsies  performed  by  the  coroners  catheters,  knitting-needles,  hat -pins, 
etc.,  have  been  found  in  the  belly,  usually  embedded  in  pus. 

Tuberculosis  of  the  peritoneum  practically  alwaj's  causes  sterility.  It  is  of 
special  interest  from  the  standpoint  of  differential  diagnosis  from  pregnancy,  many 
grievous  mistakes  having  been  made.  Montgomery  relates  the  sad  case  of  a  refined 
English  woman  who  fled  to  America  to  escape  the  gossip  of  her  former  friends  about 
her  growing  abdomen,  and  at  the  autops}^,  held  in  New  York,  the  finding  of  a 
tubercular  peritonitis  justified  her  oft-repeated  assertion  of  imiocence. 

Rupture  of  an  extra-uterine  pregnancy  may  simulate  an  acute  peritonitis,  and 
there  may  be  even  fever  of  102°  to  103°  F.  to  render  the  diagnosis  difficult.  In  all 
cases  of  acute  peritonitis  in  early  pregnancy  criminal  practices  are  first  to  be  thought 
of,  and  the  al)domen  is  to  be  opened  at  once. 

Chronic  peritonitic  adhesions  have  already  been  considered  in  connection  with 
distortions  and  displacements  of  the  uterus.  Pregnancy,  by  the  softening  and 
vascularization  of  such  bands,  may  be  actually  curative,  the  rising  uterus  stretching 
and  breaking  them.  This  process  may  be  attended  by  more  or  less  pain,  and  in  one 
such  case  the  author  had  to  prescribe  rest  in  bed  and  opiates.  Labor  in  such  pa- 
tients may  be  slow  and  tedious.  It  is  beheved  that  ''missed  labor"  occurs  more 
often  under  these  conditions.

PREGNANCY  COMPLICATED  BY  NEOPLASMS 

Tumors  in  and  near  the  uterus  may  cause  serious  (rouble  l)efore,  during,  and 
after  delivery,  though  of  late  years  the  eases  are  not  so  frecjuent  nor  so  fornu<lable 
as  formerly,  because  most  of  the  tumors  are  removed  when  found,  and,  further, 
owing  to  modern  asepsis,  infections  are  almost  always  avoided,  and  operations  dur- 
ing labor  more  successful. 

FIBROIDS 

The  effects  of  pregnancy  on  myomata  are  well  known  and  appreciated.  It  is 
not  believefl  that  the  changes  incident  to  gestation  directly  cause  myomatous  forma- 
tions, though  perhaps  the  infections  posti)artum  may  lay  the  foundation  for  their

and  rise  into  the  abdomen,  which  is  fortunate,  because  otherwise  they  would  block 
delivery.  This  retraction  of  the  tumor  above  the  brim  may  occur  even  during 
labor,  and  the  accoucheur  may  be  most  agreeably  surprised  to  find  what  promised 
to  be  a  formidable  case  become  a  simple  matter.  The  fibroid  may  be  flattened  by 
the  growing  ovum,  or,  if  there  are  several  tumors,  they  may  be  separated  from  each 
other.  Subserous  myomata  may  become  twisted  and  necrose,  or  they  may  pro- 
lapse into  the  pelvis;  interstitial  tumors  usually  become  more  superficial;  sub- 
mucous fibroids  are  likely  to  become  polypoid  and  may  then  be  extruded  through 
the  cer\'ix  durhig  the  puerperium.  During  labor  the  fibroids  may  be  crushed  by 
the  advancing  head,  bj^  attempts  at  delivery,  or  by  too  strong  "Crede"  expression. 
In  the  puerperium  myomata  usually  undergo  involution  with  the  rest  of  the  uterus. 


Fig.  456. — Mrs.  K.     Mitral  Cervical  Fibroids  at  Beginning  of  Labor. 

Many  authors  report  the  total  disappearance  of  the  tumors  asthe  result  of  involution, 
but  I  have  not  observed  it  in  the  few  cases  I  have  been  able  to  follow  up,  the  tumors 
all  having  been  found  as  large  as,  or  even  larger  than,  they  were  before  pregnancy, 
though  smaller  than  they  were  during  gestation.  Landau  says  the  same.  Necrosis 
and  infection  of  the  tumors  occur,  but  this  accident  is  unusual,  is  favored  by  immense 
size  of  the  growth,  by  bruising  during  delivery,  but  particularly  by  infection,  which 
is  invited  by  the  wounding  of  the  endometrium  over  the  tumor.  The  fil)roid  may 
be  converted  into  a  necrotic,  purulent  mass  which  breaks  into  the  ])la(lder  or  dis- 
charges per  vaginam,  a  cure  thus  being  effected.  Sometimes  the  uterine  contractions 
deliver  the  tumor  outside  the  cervix  or  vulva,  the  capsule  breaks,  and  the  myoma 
escapes  through  the  rent,  but  more  often  gangrene  sets  in,  requiring  operation. 
The  influence  of  pregnancy  on  the  symptoms  caused  by  myomata  is  also  one  of

aggravation.  Pain  was  niarkotl  in  all  my  ca.ses,  iK-inorrhago,  .simulating  threatened 
abortion,  in  one.  If  the  tumor  is  large,  the  symptoms  of  abdominal  overdi-stention 
result,  together  with  wasting  and  even  caehexia. 

The  effects  of  the  fibromata  on  the  pregnancy  are  very  variable.  Women  with 
such  tunK^rs  are  frequently  sterile,  and  though  Martin  says  this  is  not  true,  larger 
statistics  seem  to  prove  it.  Al>orti<Mi  is  more  aj)t  to  occur,  especially  with  the  sub- 
mucous varieties.  The  interstitial  have  less  influence,  and  the  subserous,  unless  large 
or  near  the  cervix,  hardly  any.  Placenta  pritvia  seems  to  be  favored  by  the  pres- 
ence of  uterine  tumors,  prol)ably  through  the  conccjmitant  endometritis  or  edema. 
Ketroflexio  uteri  gravidi,  with  incarceration,  has  been  noted.  In  labor  the  fibroids 
usually  do  not  give  troul)le  unless  imi)acted  or  adherent  in  the  pelvis,  or  unless  the

placenta  has  attached  itself  to  the  tumor.  A  subserous  impacted  myoma  causes 
the  worst  trouble,  because  it  is  less  likely  to  be  elevated  by  the  contracting  and  re- 
tracting uterus  (Figs.  450  and  457).  Interstitial  tumors  may  be  flattened  against 
the  wall  of  the  jielvis,  so  that  they  allow  the  child  to  i)a.ss;  they  may  l)e  retracted 
upward,  or,  if  low  in  the  cervix,  they  may  be  pushed  out  of  the  vulva,  even  delivered 
free,  thus  permitting  the  l)irth  of  the  child.  The  last  occurrence  is  more  likely  with 
fibroid  jmlyiM.  Fibromyomata  exert  an  influence  on  the  mechanism  of  labor.  The 
pains  are  usually  strong;  indeed,  when  delivery  is  l)locked  i)y  tiie  tumor.  rui>ture  of 
the  uterus  may  ensue;  on  the  other  hand,  weak  j^ains,  even  atony,  may  be  j^resent; 
abnormalities  of  position  and  presentation,  face,  forehead,  breech,  shoulder,  are 
prone  to  occur;  prolapse  of  the  cord,  interlocking  of  the  fetus  and  the  tumor,  and 
inversion  of  the  uterus  have  also  been  noted. 


524      THE  PATHOLOGY  OF  PREGNANCY,  LABOR,  AND  THE  PUERPERIUM 

In  the  third  stage  hemorrhage  is  very  common  because  the  distorted  uterus 
has  difficulty  in  closing  the  vessels  of  the  placental  site.  Anomalies  in  the  separa- 
tion of  the  placenta  are  especially  apt  to  occur  when  it  is  located  on  the  tumor, 
since  pathogenic  adherence  is  the  rule  in  such  cases.  If  the  uterine  canal  is  kinked, 
the  placenta  may  be  incarcerated,  and  even  the  best  operator  may  not  be  able  to 
remove  it. 

During  the  puerperium  fibroids  may  obstruct  the  lochial  flow  and  cause  lochio- 
metra;  they  always  delay  involution;  they  predispose  to  phlel^othrombosis,  and 
when  they  are  infected,  the  worst  forms  of  sepsis  may  result. 

Diagnosis. — Most  complicated  diagnostic  problems  are  here  presented  to  the 


Fio.  4.57. — .SuBSERDL  s  Myoma  in  Pelvis.     Removed  through  Posterior  Colpotomy. 

obstetrician,  and  mistakes  without  number  have  been  made.  If  a  woman  who  is 
known  to  have  myomata  becomes  pregnant,  the  diagnosis  is  not  difficult  and  will  rest 
on  .some  of  these  points:  Cessation  or  irregularity  of  the  menses;  the  sympathetic 
symptoms  and  breast  signs;  the  rapid  enlargement  of  the  uterine  tumor;  the  develop- 
ment on  it  of  a  soft  area;  the  contractions  of  the  uterine  tumor;  and,  in  the  second 
trimester,  the  fetal  heart-tones.  All  these  may  be  equivocal  except  the  last,  and  even 
the  fetal  heart  may  be  inaudible  because  covered  by  an  immense  tumor.  If  the  diag- 
nosis of  the  existing  pregnancy  is  made,  it  is  usually  easy  to  determine  that  there 
are  fibroids  in  addition,  but  here,  too,  mistakes  have  occurred,  a  twin,  an  ovarian 
tumor,  pyosalpinx,  abdominal  wall  fibromata,  fat,  etc.,  having  been  taken  for 
uterine  tumors.     During  delivery  the  myomatous  nodules  are  made  prominent  when 


PREGNANCY    COMPLICATED    HY    NEOPLASMS  525 

the  uterus  hardens,  and  unless  hidden  behind  tlie  uterus,  are  ahno.st  always  dis- 
coverable. They  may  be  mistaken  for  other  tumors  or  a  second  child.  Forceps 
have  been  ai)plied  to  a  myoma  which  imposed  its  a  fetal  head.  If  located  in  a  posi- 
tion which  causes  interference  with  the  mechanism  of  labor,  new  j^roblems  are  jjre- 
sented  for  diagnosis.  When  the  uterus  is  emptied,  its  large  size  and  the  presence 
of  nodules  will  easily  indicate  the  trouble,  tlujugh  on  one  such  occa.>ion  six  talented 
gynecologists,  from  external  examination,  diagnosed  a  second  twin.  In  the  puer- 
perium  the  fundus  remains  high,  involution  proceeding  very  shjwly.  Infection 
of  the  tumor  is  anncjunced  by  the  usual  signs  of  sepsis. 

The  differential  diagnosis  between  a  large  synuiietrie  interstitial  Hbroid  and 
pregnancy  is  sometimes  one  of  the  most  difficult  to  make.  Times  innumerable  the 
belly  has  been  opened  and  only  the  normal  pregnant  uterus  found,  and,  indeed,  it 
may  be  almost  impossible  to  distinguish  the  two,  even  after  the  tumor  is  out  (jf  the 
belly,  in  the  hands  of  the  operator. 

In  such  a  case  nuieli  weight  is  to  be  placed  on  careful  and  repeated  examinations 
made  before  operation:

9.  A'-ray  negative  unless  tumor  is  c:>lcareous.         9.  May  outline  skeleton  of  fetus. 

After  the  belly  is  opened,  the  differential  tliagnosis  is  made  by  the  darker  color 
of  the  pregnant  uterus,  the  congested,  thickened  tubes  and  ligaments,  the  presence 
of  a  large  corpus  luteum  in  one  ovary,  ballottement,  the  contractions  of  the  tmnor, 
which  molds  itself  on  the  promontory,  while  a  hljroid  is  usually  lighter  in  color, 
rocks  heavily  on  the  promontory,  is  asymmetric,  and  the  experienced  operator 
usually  can  determine  from  the  feel  whether  or  not  a  pregnancy  exists.  If  the  doul)t 
cannot  be  dispelleil,  it  is  justifiable  very  slowly  to  cut  into  the  tumor,  layer  by  layer, 
and,  should  an  (jvum  \)v  discovered,  imless  other  indications  exist,  the  wound  is  to 
be  immediately  sutured  and  the  belly  doseil.  Pregnancy  is  usually  n(jt  interrujJtetl 
by  the  exploratory  operation. 

Prognosis. — Without  doubt  the  dangers  of  myomata  complicating  pregnancy 
are  misre])rescnted  by  the  reports,  which  is  due  to  the  fact  that  only  the  bad  ca.ses 
are  considered  worthy  of  publication.  Wertheim,  in  ([Uoting.  gives  a  niortality  of 
50  per  cent,  for  the  mothers  ami  57  to  GO  per  cent,  for  the  children,  and,  in  atldition, 
30  per  cent,  of  abortions.  These  figures  are  decidedly  too  high.  Unless  the  tumor 
olxstruets  drjivery.  recovery  is  the  rule,  but  the  fetus  is  more  endangered. 

Treatment  in  Early  Pregnancy. — Since  the  majority  of  pregnant  women  with 
fibroids  go  to  and  through  labor  without  difficulty,  it  is  almo.-^t  never  necessary 
to  induce  abortion  on  their  account.  Indeeil,  the  interruption  of  pn>gnancy  is 
difficult  because  of  the  distortion  of  the  uterine  canal,  and  dangerous  Ix'cause 
of  the  hemorrhage  and  liability  of  infecting  the  tmnors.  Excessive  pain  and  re- 
peated and  profuse  hemorrhages  may  require  treatment,  and  if  ordinary  means 
do  not  suffice,  an  operation  may  be  necessiiry.  It  is  In'st.  wluTcver  at  all  {xx-^i- 
ble,  to  wait  until  term  or  near  it  before  operating.  It  may  even  Im^  wi.se  to  trj- 
the  test  of  labor,  because  nature  sometimes  accomplishes  wonders  in  getting  the 
tumors  out  of  the  wav  of  the  child's  deliverv.     In  the  absence,  therefore,  of  un-

bearable  pain,  of  severe  hemorrhage,  of  very  rapid  growtli  (the  "galloping  t^-pe" 
of  Pozzi),  of  great  distress  from  overdistention  of  the  belly,  and  of  signs  of  necro- 
sis of  the  tumor,  it  is  justifiable  to  wait  and  watch.  To  assist  nature  in  elevating 
the  tumors  out  of  the  pelvis  the  patient  assumes  the  knee-chest  position  frequently 
every  day,  IMyomectomy  has  l)een  frequently  done  during  pregnancy,  but  it  is  a 
very  bloody  operation,  and  is  followed  by  abortion  in  17  per  cent,  of  cases  (Win- 
ter). Hysterectomy  has  also  been  performed,  sometimes  when  only  enucleation 
of  the  tumors  was  intended,  but  made  necessary  because  of  technical  difficulties, 
hemorrhages,  etc. 

Near  Term  or  in  Labor. — (a)  Clean  Cases. — Should  the  woman  approach  the 
end  of  her  pregnancy,  a  careful  examination  is  made  to  determine  whether  the  tu- 
mors will  obstruct  labor,  and  it  must  be  borne  in  mind  that  a  degree  of  contraction  of 
the  parturient  passage  caused  by  a  fibroid  is  worse  than  the  same  caused  by  a  con- 
tracted pelvis,  because  of  the  possible  sloughing  of  the  tumor  resulting  from  crushing 
during  spontaneous,  but  especially  operative,  delivery.  Even  during  pregnancy 
gentle  attempts  at  reposition  are  allowable.  Should  a  subserous  or  mural  cervical 
myoma  be  so  large  or  so  firmly  fixed  in  the  pelvis  that  it  apparently  will  completely 
block  delivery,  cesarean  section  is  to  be  performed  as  soon  as  labor  has  declared  itself. 
When  the  patient  is  anesthetized,  it  is  justifiable  to  make  an  attempt  at  manual  re- 
position of  the  tumor.  If  it  succeeds,  labor  is  allowed  to  continue ;  if  not,  abdominal 
delivery  is  performed.  After  the  child  and  placenta  are  removed,  an  attempt  is  to  be 
made  to  raise  the^ tumor  out  of  the  pelvis  and  to  extirpate  it.  If  this  is  impossible  be- 
cause the  fibroid  is  too  densely  adherent,  or  because  it  has  grown  out  into  the  broad 
ligaments,  the  question  of  total  extirpation  comes  up.  Only  a  skilful  obstetric  sur- 
geon may  attempt  such  an  operation.  Hemorrhage  is  often  profuse.  It  may  be 
wiser  to  leave  the  tumor  for  future  removal.  Drainage  of  the  uterine  cavity  into 
the  vagina  with  gauze  is  to  be  provided. 

(6)  Suspect  Cases. — When  labor  has  been  in  progress  for  a  long  time;  when  the 
woman  is  presumably  infected;  or  where  unsuccessful  attempts  at  delivery  or  re- 
position of  the  tumor  have  been  made — the  condition  becomes  very  formidable. 
Here,  unless  manual  reposition  under  anesthesia  succeeds,  the  abdomen  must  be 
opened.  Now,  if  at  all  possible,  the  tumor  is  to  be  raised  out  of  the  pelvis,  and  de- 
livery from  below  executed  by  an  associate;  then  supravaginal  amputation  or  total 
extirpation  performed..  If  the  child  is  dead,  it  is  best  to  remove  the  uterus  en  bloc, 
without  opening  it  to  extract  the  child,  the  object  being  to  prevent  the  contact 
of  the  infectious  uterine  contents  with  the  peritoneum.  In  deciding  whether  or 
not  to  remove  the  uterus  it  may  be  necessary  to  consult  the  wishes  of  the  patient 
and  her  husband,  because  if  the  child  is  dead,  they  may  wish  progeny  later.  In 
presumably  infected  cases  the  danger  of  peritonitis  should  be  pointed  out,  and  the 
removal  of  the  uterus  advised  as  a  means  of  reducing  it.  In  clean  cases  the  enuclea- 
tion of  the  tumor  may  be  attempted,  or  even  the  whole  mass  left  for  removal  at  a 
future  labor  or  intermediate  operation. 

(c)  Smaller  tumors  may  be  left  for  the  test  of  labor,  and,  as  a  rule,  they  will  be 
retracted  or  softened  and  flattened  so  as  to  allow  the  passage  of  the  fetus.  If  they 
are  very  low  in  the  cervix  or  pedunculated,  they  may  be  enucleated  or  amputated 
through  the  vagina.  Labor  may  then  be  allowed  to  proceed  naturally,  or  if  the 
conditions  are  fulfilled,  delivery  is  effected.  Enucleation  is  not  to  be  attempted 
unless  the  tumor  is  quite  superficial  and  its  shelling-out  promises  to  be  very  simple, 
because  sometimes  hemorrhage  is  so  profuse  that  the  belly  has  to  be  hurriedly 
opened  to  control  it. 

In  conducting  a  lal^or  with  fibroids  abutting  on  the  parturient  canal  it  is  im- 
portant to  avoid  all  bruising  of  the  tumors,  because  necrosis  and  infection  are  so 
liable  to  set  in  afterward.     In  making  a  reposition  of  the  tumor  the  utmost  gentle-

ness  is  to  be  practised,  because  its  capsule  nmy  l»e  rui)turetl  or  its  pedicle  injured, 
resulting  in  intra-abdominal  hemorrhage  or  sloughing,  with  subsequent  peritonitis. 
In  trying  to  pull  a  fibnjid  out  of  the  pelvis  with  the  belly  opened  nmch  aid  is  afforded 
by  an  associate  pushing  the  tumor  upward  gently  from  below.  If,  now.  the 
delivery  can  be  accomj)lish('d  through  the  vagina  and  the  oiK'ration  completed 
without  establishing  connection  between  the  peritoneal  cavity  and  the  parturient 
canal,  a  distinct  advantage  is  gained. 

Operations  in  the  utcrin*'  cavity,  as  version  and  manual  removal  of  the  pla- 
centa, may  be  rendered  lal)orious  by  obstructing  fibroid  tumcjrs,  and  it  may  be 
necessary  to  push  up  or  even  extirpate  the  masses  before  the  hand  can  be  introduced. 
Removal  of  a  placenta  atlherent  to  a  submucous  fibroid  may  require  the  digging- 
out  of  the  two  at  once,  whereby  care  is  observed  not  to  puncture  the  uterus.  In 
such  an  event,  or  if  the  extraction  of  the  placenta  fails,  abdcjininal  section  would  be 
indicated.  If  not  in  position  to  perform  major  oj^erations,  and  finding  it  imjxjssible 
to  remove  the  placenta,  the  accoucheur  should  pack  the  uterovaginal  canal  firmly 
^^^th  gauze.  After  forty-eight  to  six-ty  hours  of  tamponade  the  placenta  will  usually 
be  found  loose  enough  for  easy  delivery. 

During  the  jnieriMTium,  unless  sym])toms  are  present,  the  myomata  are  not 
disturbed.  Ergot  is  best  omitted  unless  the  tumor  is  pedunculating  itself  ready  for 
extrusion  and  the  same  is  to  be  hastened.  Signs  of  gangrene,  fever,  fetid  lochia,  etc., 
repeated  hemorrhages,  and  e\'idences  of  spontaneous  exirusion  of  the  tumor  may 
refjuire  interference.  In  three  cases  I  was  able  to  eimcleate  the  sloughing  tumor 
per  vaginam,  but  in  another  abdominal  extirj^ation  was  necessary  in  the  sixth  week 
postpartum.  During  a  laparotomy'  for  sloughing  fibroids  the  peritoneum  is  to  be 
walled  off  as  carefully  as  at  all  possible,  and  the  cutting  across  of  the  pedicle,  after 
ligation  of  the  broad  ligaments,  done  with  the  Pacjuelin  cautery.  Drainage  through 
the  vagina  follows.     The  peritoneum  nmst  not  be  contaminated. 


CARCINOMA  CERVICIS 

Of  16,000  consecutive  ol)stetric  cases  at  the  Chicago  Lying-in  Hospital  and 
Dispensary,  (jnly  one  was  comjilicated  by  cancer  of  the  cervix,  and  since  the  service 
here  most  closely  resembles  private  practice,  as  opposed  to  an  exclusive  hosjiital 
ser\'ice,  this  may  be  taken  as  a  fair  intlex  of  the  frequency  of  the  condition,  though 
Sarwey,  comljining  many  statistics,  gives  the  ratio  as  1  to  2000  lalxjrs,  which  agrees 
with  Kerr's  figures.  To  the  fact  that  cancer  occurs  mostly  in  the  non-reprotluctive 
period,  we  can  ascril)e  its  rarity  as  a  complication  of  pregnancy.  It  occurs 
almost  exclusively  in  multipanc.  It  is  a  most  unfortunate  complication,  since  of 
reported  cases  43  p(T  cent,  of  the  mothers  and  00  per  cent,  of  the  children  died 
during  labor  (Wertiieim). 

The  effect  of  pregnancy  upon  the  cancer  is  unfavorable.  Rarely  the  gro^^•th 
begins  after  conception;  usually  the  pregnancy  superven<'S  after  the  cancer  has 
started.  Owing  to  the  vascularization  and  l>nnphatic  imbibition  of  the  cervix 
caused  by  pregnancy  the  tumor  grows  fast  and  invades  the  l>nnphatics  and  glands 
very  ([uickly.  Hemorrhage  and  necrosis,  with  j)Utrid,  sanious  leukorrhea,  are  very 
marked  in  all  cases  except  the  slow-growing  epithelioid  varieties.  Labor  may 
break  up  the  tumor,  the  more  or  less  deep  lacerations  causing  hemorrhage,  sej^sis, 
and  rapid  extension  of  the  neopla.sm.  In  tlie  puer]>erium  the  last-mentioned  changes 
become  evident,  l)ut  the  jirostration  and  (juick  cachexia  are  most  striking. 

Upon  pregnancy,  labor,  and  the  ])ueri)erium  cancer  of  the  cervix  exerts  a  bad 
influence.  In  the  first  place,  sterility  is  tlie  rul(>  in  cancer.  esjMrially  in  advanced 
cases,  for  olivious  reasons;  second,  abortion  is  frecjuent.  U'cause  of  the  endometritis 
usually  present,  the  infection  and  death  of  the  ovum,  the  hemorrhages,  and  the

restriction  of  the  gro\\'th  of  the  uterus  by  the  neoplasm.  Lal)or  is  olistructed,  not 
SO  much  because  of  the  size  of  the  mass,  as  because  of  the  rigidity  of  the  cervix  pro- 
duced by  the  carcinomatous  infiltration.  If  the  tumor  is  soft  and  takes  up  part  of 
the  cer\'ix,  the  rest  ma}'  cUlate  and  allow  the  child  to  pass.  If  the  whole  cervix  is 
involved  and  in  a  hard  mass,  obstruction  is  produced,  and  the  case  is  formidable. 
Placenta  prae\'ia  is  a  not  very  uncommon  complication,  and  because  of  the  fria- 
bihty  of  the  uterine  wall  near  the  tumor,  rupture  of  the  uterus  may  occur  if  the 
pains  do  not  quickly  succeed  in  overcoming  the  resistant  cervix.  Should  the  cer\nx 
give  Avay,  the  tear  ma}'  extend  up  into  the  parametrium,  gi\'ing  rise  to  terrific  hemor- 
rhages, which,  o^nng  to  the  friable  nature  of  the  parts,  cannot  be  stopped  by  suture. 
Missed  labor  has  been  observed,  also  premature  rupture  of  the  membranes,  and 
primary  and  secondary'  uterine  inertia.  Sepsis  is  common  in  the  puerperium,  and 
a  cancerous  puerpera  is  a  menace  to  other  puerperae  in  the  same  ward. 

Diagnosis. — Every  woman  who  has  irregular  hemorrhages  or  purulent  or 
putrid  leukorrhea  should  be  examined  for  cancer  of  the  uterus,  and  even  if  the  meno- 
pause has  taken  place,  pregnancy  should  be  suspected  when  the  uterus  is  found  en- 
larged. The  usual  criteria  of  cancer  are  available,  and  the  tumor,  hard  and  nodular, 
is  more  easily  differentiated,  since  the  cervix  is  softened.  I  have,  on  two  occasions, 
found  a  hard,  nodular,  but  not  ulcerative  condition  of  the  cervix  during  the  middle 
of  pregnancy,  attended  by  slight  bleedings  and  fetid  discharge,  but  which  were  not 
carcinomatous  and  w'hich  disappeared  after  delivery.  It  is  wise,  therefore,  in 
doubtful  cases  to  examine  a  piece  of  the  tumor  microscopically.  Pregnancy  will 
not  be  interrupted  by  exsecting  a  bit  of  the  cervix. 

Treatment. — If  an  operable  cancer  of  the  cervix  is  discovered  in  the  early 
months  of  pregnancy,  this  question  arises:  In  view  of  the  fact  that  recurrence  in 
such  cases  is  so  quick  after  delivery  and  the  woman,  therefore,  doomed  to  early 
death,  would  it  not  be  best,  in  the  interests  of  the  child,  to  wait  until  the  termination 
of  pregnancy?  Pinard,  Pozzi,  and  most  French  authors  say  yes,  but  the  German 
and  American  authorities  believe  in  the  immediate  radical  operation.  The  family 
must  decide,  it  being  explained  to  them  that,  by  waiting,  the  time  for  radical  cure, 
which  obtains  in  25  per  cent,  of  cases,  is  lost,  and  the  cancer  may  become  inoperable, 
the  death  of  the  woman  being  thus  hastened  by  at  least  two  years.  If  operation 
is  chosen,  the  abdominal  extirpation  offers  the  best  hope  of  cure,  but  the  vaginal 
route  still  has  mam^  adherents.  Spencer,  Glockner,  and  Beckman  found  50  and  82 
per  cent,  of  cases  of  cancer  in  pregnancy  operable. 

Should  the  carcinoma  be  discovered  when  the  child  is  near  viability,  it  may  be 
justifiable,  in  its  interest,  to  wait  a  few  w^eeks.  After  viability  there  is  no  question 
as  to  the  necessity  of  interference  in  operable  cases,  and  most  authors  agree  that 
the  vaginal  cesarean  section,  followed  at  once  by  extirpation  of  the  uterus,  is  the 
operation  of  choice.  Technically,  the  operation  is  rendered  difficult  by  the  rigidity 
of  the  parts,  and,  if  the  cancer  is  on  the  anterior  wall,  it  may  require  careful  dis- 
section to  free  the  bladder,  but  this  is  absolutely  necessary.  In  the  extirpation  of 
the  uterus  which  follows  the  delivery  of  the  placenta  it  may  be  helpful  to  split  the 
uterus  in  two.  Zweifel  recommended  cesarean  section  and  amputation  of  the 
uterus,  followed  by  extirpation  of  the  cervix  and  tumor  from  beloAV.  English 
operators  prefer  the  abdominal  panhysterectomy  after  delivery  of  the  child,  and 
proceed  in  the  same  fashion  as  in  non-pregnant  cases. 

When  pregnancy  supervenes  on  an  inoperable  carcinoma,  the  woman  is  allowed 
to  go  to  term,  and  local  treatment,  as  curetage,  cauterization,  and  tamponade, 
performed  only  if  hemorrhage  or  sepsis  demands  it.  Abortion  is  not  invariably 
produced  by  such  interference.  At  term,  pains  are  not  awaited,  but  cesarean  sec- 
tion is  performed,  the  uterus  amputated  as  low  as  possible,  the  peritoneum  closed 
over  the  stump,  and  a  drain  through  the  cervix  into  the  vagina  left.

OVARIAN  TUMOPS 

Much  rarer  tlian  fibroids  are  ovarian  tumors  < luring  pregnancy.  Since  cysts 
of  the  ovary  are  quite  common,  the  conclusion  is  justified  tliat  they  predispose 
to  steriHty.  In  802  cases  collected  by  McKerron,  simple  and  multilocular  cysts 
occurred  in  <)8  per  cent.;  dermoids,  in  2'.i  per  cent.;  fibnjmata  and  solid  adeno- 
mata, in  2  per  cent.,  and  malignant  neoplasms,  in  o  per  cent. 

The  influence  of  pregnancy  on  the  tumor  is  usually  not  bad,  most  women  going 
to  term  without  the  knowledge  of  its  existence,  and  the  growth  of  the  netjplasm  is 
not  accelerated,  as  in  the  case  of  fibroids.  While  dyspnea,  palpitation,  etc.,  due  to 
excessive  size  of  the  tumor,  are  exceedingly  rare,  t(jrsion  (^f  the  i)edicle,  hemorrhage 
into  the  cyst,  suppuration,  and  necrosis  have  occasionally  Ijeen  noted.  Labor 
exerts  no  influence  unless  the  tumor  lies  in  the  pelvis,  exposed  to  the  traumatism 
of  delivery.  In  this  case  it  may  be  crushed  or  burst,  or  its  pedicle  torn,  while  in 
some  instances  the  advancing  heatl  has  h^rccd  the  tumor  through  the  rectum  or  the 
vagina  outside  the  Ijody — a  spontaneous  ovariotomy.  The  jjuerperium  shows  no 
special  influence,  but  complications  are  likely  to  arise  as  the  result  of  the  bruising 
of  the  tumor.     Torsion  has  been  (observed  much  more  frec}uently  than  usual. 

Pregnancy  is  but  little  affected  In'  ovarian  cysts.  Abortion  is  commoner  only 
with  those  tumors  which  are  very  large  or  are  incarcerated  in  the  jx'lvis,  interfere 
with  the  growth  of  the  uterus,  or  become  twisted  or  infected.  Hydatid  mole  has 
been  frequently  observed,  sometimes  with  lutein  cysts.  Upon  labor,  ovarian  cysts 
exert  a  bad  action  only  when  they  are  incarcerated  in  the  pelvis  and  block  the  path 
of  the  child.  To  a  certain  extent,  but  not  so  nmch  as  with  fibroids,  nature  heljjs 
herself  b}'  drawing  the  tumor  out  of  the  way  by  means  of  the  pedicle,  and  a  small  or 
soft  tumor  may  still  allow  the  passage  of  the  child.  A  soft  tumor,  however,  when 
it  diminishes  the  available  pelvic  cavity,  is  far  worse  than  an  equal  amount  of 
contraction  caused  l)y  defcjrmed  jielvis.  The  puerperium  is  often  stormy,  since, 
because  of  the  bruising  of  the  tumor,  necrosis,  hemcjrrhages,  infection,  suppuration, 
sometimes  with  breaking  of  the  pus  into  the  neighl)oring  organs,  occur.  Tumors 
which  become  adherent  to  the  rectum  are  likely  to  be  infected  ^\'ith  colon  bacilli. 
Dermoids,  in  the  writer's  experience,  are  the  wonst  cases  in  all  respects. 

Diagnosis. — In  tiie  early  months  it  is  usually  very  easy  to  diflerentiate  the 
pregnant  uterus  fnjm  the  roundetl,  moval)le,  pedunculated  tumor  lying  at  its  side, 
but  sometimes  great  difficulties  are  encountered.  When  the  tumor  is  intraliga- 
mentous or  prolapsed  in  the  pelvis  behind  the  uterus,  a  careful  differentiation  from 
ectopic  gestation  and  retnjflexed  gravid  uterus  must  be  made.  Both  of  these  iiave 
already  been  c(Misidered  under  their  respective  headings  (cj.  /•.).  A  large  tumor  may 
conceal  the  uterus  and  pose  as  a  pregnancy,  and  since  the  signs  and  symptoms  of 
the  latter  are  present,  the  mistake  is  very  likely  to  be  made. 

In  the  later  mcMiths,  and  during  labor,  the  location  of  the  tumor  cau.ses  a  variety 
of  difficulties.  If  iiigii  in  tiie  abdomen,  it  may  sliji  under  the  liver  and  spleen.  If 
adherent  to  the  uterus,  the  .suspicion  of  twins,  of  fibroid,  or  double-horneil  uterus, 
arises.  If  attachetl  to  the  pelvis  low  tlown,  a  shoulder  presentation  may  be  thought 
of.  In  one  of  my  cases  a  dermoid  was  adherent  to  the  promontory  of  the  sacrum 
and  could  just  be  reached  by  the  examining  finger.  If  the  head  had  not  been  i)ushed 
far  forwartl  over  the  pubis  l)y  .something  behind  the  uterus,  it  is  more  than  probaiile 
that  the  tumor  would  have  been  overlooked.  Tumors  incarcerated  in  the  pi-lvis 
during  labor  are  very  easily  discoveretl,  but  their  nature  and  origin  are  not  so  quickly 
determined.  A  cyst  under  the  compression  of  laiior  becomes  as  liard  as  a  fibroid, 
and  if  it  is  adherent,  may  sinuilate  a  tumor  of  the  pelvic  periosteum,  as  occurred  in 
one  of  my  cases.  Rectal  examination  will  exclude  this  da.ss  of  neoplasms.  An 
ovarian  cyst  has  been  held  to  be  the  head  of  a  second  twin,  and  forceps  apjilied;  a 
fibroid — andenucleationattempted;  a  prolapsed  kidney;  a  full  rectum;  a  hematoma.

THE  PATHOLOGY  OF  PREGNANCY,  LABOR,  AND  THE  PUERPERIUM 


An  important  part  of  the  diagnosis  is  the  decision  as  to  whether  the  tumor  Avill 
block  the  dehvery,  and  in  estimating  this  one  must  never  forget  to  measure  the  bony 
pelvis  also. 

Prognosis. — Nowadays  few  women  die  from  this  complication  because  the 
tumors  are  usually  removed  as  soon  as  found,  and  because  operation  is  substituted 
for  the  brutal  obstetric  deliveries  of  the  olden  time.  ]\Iarshall,  in  the  latest  collec- 
tion, finds  a  maternal  mortality  of  only  3.3  per  cent,  in  cases  operated  on  during 
pregnancy,  and  o  per  cent,  after  lai)arotomy  at  term.  I  believe  this  is  too  favorable 
a  report,  since  many  bad  results  are  not  published.     Wertheim  quotes  two  statis-

Treatment. — During  Pregnancy. — Most  authors  are  strongly  in  favor  of  im- 
mediate removal  of  the  tumor  when  discovered,  Ijut  the  writer  agrees  with  Fehling 
and  Martin  that  here,  as  alwa^'s,  one  must  individualize.  Operation  is  the  rule, 
preferably  laparotomy,  though  Dtihrssen  urges  the  vaginal  route.  Abortion  follows 
the  operation  in  22.5  per  cent,  of  cases  (Orgler),  and  even  though  it  follows  in  17 
per  cent,  of  cases  treated  expectantly,  it  may  l^e  wiser  to  postpone  the  removal  of 
the  tumor  until  the  last  month  of  pregnancy  or  during  labor  or  the  puerperium. 


PREGNANCY    COMPLICATED    BY    NEOPLASMS  531 

Such  exceptions  to  the  rule  would  l)e:  (1)  Small,  freely  movable  tumors  high  in  the 
abdomen;  (2)  an  aj^ed  ])rimii)ara  in  whom  the  j)robability  of  further  prej^naneies  is 
slight;  (3)  doul)le  ovarian  tuiiujrs  win-re  the  woman  has  no  children  and  desires 
offspring.  In  these  cases,  if  operation  nmst  be  done,  a  part  of  the  ovarj'  should, 
where  possible,  be  left.  Should  the  patient,  after  the  situation  in  all  its  bearings 
has  been  explainetl  to  her,  tleeitle  to  wait,  she  nmst  be  in.structed  to  rejjort  at  once 
any  untoward  symptom,  and  as  the  time  of  her  confinement  approaches.  s<*ek  a  good 
maternity  hospital.  If  the  pelvis  is  not  obstructed,  labor  maN'  be  allowed  to  take 
place  as  usual,  and  the  tumor  extirpated  with  deliberation  a  few  days  aftenvard. 

Inilications  for  innnediate  operation  in  pregnancy  are:  Tcjrsion  of  the  pedicle; 
signs  of  infection  of  the  tumor;  incarceration  in  the  jx'lvis;  br(ja<l-ligament  develop- 
ment; overdistention  (^f  the  belly.  If  general  anesthesia  is  employed,  ether  should 
be  used;  the  i)regnant  uterus  nmst  be  hantlled  as  little  and  as  gently  as  po.ssible, 
and  morphin  is  to  be  given  for  several  tlays  afterward  in  an  attempt  to  restrain 
uterine  action. 

During  Labor. — A  sharp  distinction  is  to  be  made  between  ca.ses  in  the  h(jsj)ital 
under  the  hantls  of  the  ol)stetric  surgeon  and  those  at  home  in  the  care  of  the  family 
practitioner.  The  location  of  the  neoplasm;  the  state  of  the  parturient  canal  as 
regards  infection,  and  the  tumor  as  regards  prolonged  pressure,  bruising  from  at- 
tempts at  reposition,  delivery,  etc.,  are  also  to  be  thoughtfully  <-onsi(lere<l.  The 
following  lines  of  procedure  have  been  follow«'d:  (a)  Forceful  delivery  ahjngside  the 
tumor,  mentioned  first  to  l)e  uncjualifiedly  condenmed  and  thus  disposed  of;  (6) 
reposition  of  the  tumor,  followed  by  spontaneous  or  operative  delivery;  ic)  punc- 
ture or  incision  and  evacuation  of  the  cyst,  succeeded  by  delivery  from  below, 
then  removal  of  the  sac;  (d)  vaginal  ovariotomy;  ie)  abd(jminal  ovariotomy,  fol- 
lowed by  delivery  from  below;  (/)  cesarean  section,  followed  by  extiri)ati<jn  of  the 
tumor,  with  or  without  the  uterus. 

In  all  cases  the  first  procedure  is  an  attempt  to  dislodge  and  replace  the  tumor 
above  the  brim,  out  of  the  way  of  the  advancing  head.  This  is  to  be  matle  in  deep 
anesthesia,  the  i)atient  lying  in  the  Trentleienburg  or  the  «>xaggerated  Sims  position 
(Fig.  o57j;  the  fetal  head  is  to  be  pushed  upward,  and  then,  with  the  uttermost 
gentleness,  using  the  whole  hand,  the  tumor  is  tlisengaged  from  the  jx^lvis.  If  the 
mana'uver  is  successful,  the  child  is  delivered  by  version  and  extraction  or  forceps, 
or  the  case  left  t(j  nature,  dejiending  on  the  conditions  jiresent.  After  the  delivery 
of  the  child  innnediate  lai)arotomy  is  p(»rformed  and  the  tumor  extirpated.  It  is 
Ix'st  not  to  wait  to  remove  the  cyst,  because  the  latter  may  have  been  rujitured  or 
injured  by  the  manipulations  or  delivery,  and  delay  might  mean  fatal  ix^itonitis. 

If  the  ca.se  is  a  "clean"  one.  that  is.  not  infected,  and  without  previous  inter- 
ference or  prolonged  labor,  and  a  single  attempt  at  rejiosition  fails,  laparotomy  is 
to  l)e  performed,  the  tumor  removed,  and  then  delivery  accomplislu'd  from  below. 
A  long  abdominal  incision  is  necessary;  the  uterus  may  have  to  1k'  turned  out  of 
the  belly,  antl  an  a.ssistant  may  have  to  dislodge  the  tumor  from  Ik'Iow  Ijefore  the 
mass  becomes  accessible.  After  the  tumor  is  removed,  if  tlie  uterus  cannot  1)6 
replaced  in  the  belly  (rare),  it  may  be  covered  with  hot  towels,  delivery  etTected 
from  below,  and  then  it  will  be  ea."<y  to  rei)lace.  Extensive  adiiesions,  impaction 
of  the  tumor  under  the  promontory,  and  solid  and  malignant  neoplasms  may 
render  such  a  course  impossible,  as  in  one  of  my  cases,  and  the  uterus  may  have 
to  be  emptied  in  order  to  reach  the  p«'lvis.  In  all  cases  a  consistent  attempt  is  to 
be  made  to  remove  the  tumor  whole,  becaus**  the  cont«'nts.  esix'cially  if  dermoid,  are 
likely  to  l)e  infectious.  Slu)uld  such  an  infected  ma.'<s  burst  into  the  free  ix'ritoneal 
cavity,  the  uterus  is  to  be  also  extirpated  and  vaginal  drainage  established.  In 
determining  whether  a  cyst  is  infected  or  not.  in  addition  to  the  apfx^arance,  pus, 
ichor,  and  the  odt)r,  the  history  of  inflammatory  attacks  is  imixjrtant.     A  tumor 


532      THE  PATHOLOGY  OF  PREGNANCY,  LABOR,  AND  THE  PUERPERIUM 

firmly  attached  to  the  rectum  or  colon  is  frequently  infected,  and  unusual  care 
is  to  be  observed  in  removing  it. 

Suspicious  or  inl'ected  cases  are  best  attacked  through  the  vagina — indeed, 
Diihrssen,  Wertheim,  and  most  German  authorities  recommend  this  way  as  the 
rule  for  all  cases.  Spencer,  Kerr,  Hofmeier,  AMUiams,  and  most  English  and  Amer- 
ican authors  advise  the  abdominal  route. 

Vaginal  Ovariotomy. — A  long;,  preferably  longitudinal  incision  is  made  over  the  most  promi- 
nent part  of  the  tmnor,  the  cyst  grasped  with  vulsellum  forceps,  its  contents  evacuated  through  a 
broad  incision,  accessory  cavities  explored  and  emptied  with  the  finger,  and  the  sac  then  drawn  down 
and  its  pedicle  ligated.  Should  the  pedicle  be  inaccessible,  or  should  the  head  enter  the  pelvis 
upon  the  cyst  being  emptied,  the  sac  is  fixed  to  the  vaginal  opening  by  a  strong  suture,  or  the 
opening  lightly  packed  with  gauze  and  dehverj-  effected,  after  wliich  the  tumor  becomes  easih' 
managable  through  the  vaginal  incision  and  should  be  extirpated.  It  has  happened  that  laparot- 
omy became  necessary  during  the  vaginal  operation,  because  the  pedicle  could  not  be  hgated,  or 
the  tumor  was  so  brittle  that  it  could  not  be  pulled  down,  or  the  ligature  slipped,  or  the  tumor  was 
solid  or  too  densely  adherent. 

What  should  the  general  practitioner  do  in  the  home,  far  from  help?  In  the  presence  of  an 
urgent  indication  for  deli\'ery,  the  cj'st  is  to  be  punctured,  after  opening  Douglas'  pouch,  the  sac 
emptied,  anchored  to  the  vaginal  wall  by  a  suture  or  light  gauze  packing,  and  labor  completed. 
The  sac  is  to  be  extirpated  within  twenty-four  hours. 

In  the  puerperium  ovariotomy  is  to  be  performed  in  all  cases,  and  preferably  within  twenty- 
four  hours.  If  operation  is  postponed,  a  minute  watch  is  kept  for  the  first  symptoms  of  infection 
of  the  tumor  or  torsion  of  its  pedicle. 

Other  Tumors  Complicating  Pregnancy. — Reference,  onh',  may  be  made  to  those  rare  con- 
ditions which  the  obstetrician  may  meet.  They  are  all  treated  on  general  principles.  Enlarged 
and  prolapsed  kidneys,  usually  the  left  (Bland-Sutton)  (Cragin,  vaginal  nephrectomj') ;  extra- 
uterine pregnancy  combined  with  intra-uterine  (Zinke);  echinococcus  cysts  (Franta);  parametritic 
abscesses  and  infiltrates;  cancer  of  the  rectum  (Myhoff,  26  cases);  rectal  stricture;  tumors  of  the 
bladder;  vesical  calculi,  requiring  lithotomy;  bony  tumors  and  enchondromata,  to  be  considered 
later.

CHAPTER  XLIII 
MINOR  DISTURBANCES  OF  PREGNANCY 

The  accoucheur  is  often  consulted  uhout  iinnoving,  if  n(jt  dangerous,  symptoms 
durinj;  pregnancy,  and  it  is  wise  to  instruct  the  gravida  to  report  such  phenomena 
to  him,  since  he  may  detect  in  them  the  beginning  of  serious  iUness.  Slost  of  the 
troubles  have  been  considered  in  chapters  ai)i)r()priate  to  them;  here  \v\\\  l)e  men- 
tioned only  those  not  previously  treated. 

Insoninia  is  rare,  and  is  usually  due  to  digestive  disturbances  and  neurotic 
tendencies.  The  same  may  be  said  of  constant  dreaming.  If  r<'gulation  of  the 
diet  and  l>owels  does  not  suffice,  simple  remcMlies  often  will;  for  example,  one  or  two 
glasses  of  hot  malted  milk  just  before  bedtime;  a  hot-water  bag  at  the  feet ;  sleej)- 
ing  tdone,  with  a  suix-rabundance  of  fresh  air;  suggestion,  by  means  of  eleetricity, 
drugs,  warm  or  medicated  baths,  an  electric  vibrator  to  the  back  of  the  neck.  etc. 
Only  rarely  is  a  dose  of  sodium  bromid  necessary,  and  a  few  drams  of  elixir  of  chloral- 
amid  or  '>  grains  of  veronal  may  be  used  as  suceedanea — never  mor|)hin. 

Sleepiness  is  a  frecjuent  symjjtom  of  early  jiregnanc-y  and  re(juires  no  treat- 
ment. Late  in  gestation  it  is  always  to  be  regarded  with  suspicion,  iis  it  may  pres- 
age tiie  advent  of  eclampsia.     Mental  dulness  may  mean  the  same. 

Numbness  and  tingling  of  the  hands  and  feet,  usually  combinwl  with  slight 
pufhni'ss,  not  real  edema,  are  the  eviilenees  of  a  mild  neuritis,  perhaps  toxic  in 
origin.  Occasionally  local  anesthesia  and  tenderness  of  the  ccjrresponding  nerves 
are  discovered.  While  the  symptom  rarely  has  any  disturbing  sequels,  it  should 
be  watched.  Treatment  is  on  the  theory  that  it  is  due  to  to.xemia.  Neuralgias 
have  already  been  considered.  Symptoms  of  real  tetany  seldom  apix^ar,  though 
the  women  oftciitT  complain  of  cramps  and  sjiasms  in  the  arms  and  legs. 

Pain  in  the  abdomen  is  freiiuently  comiilained  of.  In  the  early  months  a 
careful  bimanual  examination  is  demanded  to  exclude  ectopic  gestation.  Pain  is  a 
symptom  of  many  conditions  which  have  already  been  considered — appendicitis, 
ureteritis,  cholelithiasis,  adhesions,  etc.  Intercostal  neuralgia  is  rare,  the  j)ain  in  the 
lower  ribs  from  which  so  many  women  suffer  being  most  often  due  to  tlraggingon 
the  thoracic  cage  by  the  recti  muscles,  which  carry  tiie  weight  of  the  large  uterus. 
An  abdominal  supporter  is  indicate<l.  Rheumatic  pains  also  occur,  and  relief 
may  b(>  (tl)taineil  from  the  use  of  a  liniment,  f<jr  example: 

i;.     Ol.  KHulthcri:!-. 

Ol.  caiiiphonit  .  aa  :iO  c.c. 

Lin.  ."^aponis  (j.  .s.  a<l  12(1  c.c. 

Most  often  the  pain  is  due  to  constipation,  with  intestinal  colic  and  Hatulence. 
Pain  associated  with  innnen.se  vulvar  varicosities  may  be  due  to  a  similar  condition 
of  the  broad  ligaments.  .\n  abdominal  binder  and  the  occa.'^ional  assumption  of 
the  knee-chest  pttsition  will  l)ring  relief.  Pain  over  the  pubis  and  in  tlu'  lower  back, 
attended  witii  ditficulty  of  locomotion,  is  often  due  to  soft<'ning  and  n'laxation  of 
the  pelvic  joints.  Stretching  of  the  skin  ami  the  f()rmation  of  stria'  gravidarum 
are  sometimes  painful.  Relief  may  l)e  obtaiii?'^'  from  lubricants,  such  as  solid 
albolene.  cocoa-i 'Utter,  or  rose-water  ointment. 

Fainting  spells,  dizziness,  and  attacks  of  weakness — if  a  thorough  examination 
excludes  organic  disease  of  the  heart,  lungs,  etc. — are  treated  symjitomatically. 
Sometimes  a  too  highlv  nitrogenous  diet  is  the  cause,  and  relief  is  obtained  through 

533 


534      THE  PATHOLOGY  OF  PREGNANCY,  LABOR,  AND  THE  PUERPERIUM 

dietary  measures.  An  iron  and  phosphorus  tonic  is  often  useful,  but  occasionally  a 
small  dose  of  digitalis  does  the  most  good.  Fresh  air  is  essential.  Palpitation  of 
the  heart  is  relieved  by  a  cold  drink,  but  if  frequently  repeated  and  not  due  to  or- 
ganic disease,  sodium  bromid,  10  grains  three  times  a  day,  may  be  given.  Dyspnea 
is  often  due  to  unhygienic  dress,  indigestion,  and  the  dragging  of  the  uterine  tumor 
on  the  chest.     It  may  be  toxemic,  hemic,  cardiac,  or  simply  neurotic  in  origin. 

Frequent  urination  is  usually  due,  in  the  early  months,  to  distraction  of  the 
base  of  the  bladder;  in  the  later  months,  to  the  restraint  of  the  distention  of  the 
viscus  by  the  large  uterus,  but  a  slight  catarrh  of  the  trigonum  is  not  rare.  The 
knee-chest  position,  a  binder,  and  a  week's  treatment  with  urotropin  and  methy- 
lene-blue  will  often  cure.  Cloudy  urine  should  not  be  present  during  normal  preg- 
nancy. When  it  does  occur,  it  is  sometimes  due  to  bacteriuria,  and  I  have  occasion- 
ally seen  it  precede  alliuminuria.  Regulation  of  the  diet,  free  drinking  of  butter- 
milk, and  urinary  antiseptics  are  indicated.  Lack  of  control  of  the  urine  on  making 
a  sudden  movement,  as  cough  or  a  jar,  is  usually  due  to  previous  injury  of  the  neck 
of  the  bladder,  with  cystocele  or  urethrocele.  The  knee-chest  posture  may  help  a 
little,  but  a  cure  cannot  be  effected  during  pregnancy.  When  a  pregnant  woman 
complains  of  urinary  troubles,  a  careful  bimanual  examination  and  urinalysis  are 
to  be  made  at  once. 

Skin  Eruptions. — Acne,  mostly  facial,  may  prove  rebellious  under  treatment. 
The  x-ray  should  not  be  used  because  the  eruption  disappears  after  labor.  Wash- 
ing the  parts  vnih  tincture  of  green  soap,  and  opening  the  pustules  with  a  fine  lancet 
comprise  the  treatment.  Urticaria  is  treated  in  the  usual  way.  The  author  has 
found  the  follo^\dng  recipe  very  useful  for  urticarial,  papular,  and  all  dry,  itchy 
eruptions : 

IJ.       Zinoi  oarbonatis  prsecip., 

Zinci  oxidi aa    30  gm, 

Mentholis, 

Ac.  carbolici aa      1  gm. 

Aqufe  calcis ad  250  c.c. 

M.  et  Sig. — External  use. 

For  the  eczema  intertrigo  in  the  genital  creases  and  under  the  breasts  of  fat 
women  frequent  ablution  with  tar-soap  and  water,  followed  by  verj^  careful  drying 
and  a  dusting-powder  of  zinc  stearate,  will  usually  suffice.  If  these  fail,  starch  and 
a  small  amount  of  salicylic  acid  may  be  added  to  the  powder.  Rarel}^,  a  salve  con- 
taining boric  acid,  2  per  cent.,  carbohc  acid,  3^  per  cent.,  zinc  oxid  and  rose-water 
ointments,  of  each  a  sufficient  quantity,  will  be  necessary.  If  leukorrhea  or  myco- 
sis is  present,  proper  treatment  is  needed.     (See  Vulvitis.) 

Pityriasis  versicolor,  occurring  principally  on  the  chest,  shoulders,  and  back, 
and  due  to  the  Microsporon  furfur,  is  easily  removed  by  frequent  scrubbing  with 
tar-soap  and  hot  water,  followed  by  washing  with  vinegar  or  1  :  1500  bichlorid. 

Edema  of  the  extremities  always  commands  attention,  because,  while  many 
instances  are  due  to  stasis,  the  swelling  disappearing  when  the  woman  lies  down, 
most  of  them  are  toxemic  or  nephritic  in  origin. 


CHAPTER  XLIV 
DISEASES  OF  THE  OVUM 

Under  this  hcadiiij:;  will  he  considered,  hrietiy,  tlie  discuses  of  the  fetus,  tera- 
tology, the  path()io<!;y  of  the  fetal  udnexa',  the  chorion,  the  lunnicjn,  and  the  uinhilical 
cord. 

The  Fetus. — To  .J.  W.  Ballantyne  is  due  the  cretlit  of  having  a.ssenii>l<-d  our 
knowledge  of  the  affections  of  the  unborn  child,  and  having  really  created  a  depart- 
ment of  ine(Hcine — antenatal  pathology. 

Most  of  the  acute  infectious  diseases  of  the  mother  have  been  demon.strated  in 
the  child,  as  has  already  been  shown.     Chronic  infectious  di.sea.ses,  tuberculosis, 
and  sj-philis,  the  former  rarely,  the  latter  usually,  pa.ss  over  also.     The  fetus  may 
become  diabetic  or  toxemic  from  its  mother,  though 
leukemia  has  not  yet  been  proved  to  affect  it.     Icterus 
of  the  motlier  sometimes  does  antl  sometimes  does  not 
discolor  the  child.     Icterus  from  toxemic  causes  is  very 
fatal  to  the  fetus.     Opium,  alcohol,  chloroform,  ether, 
the  iodids,  methylene-blue,  etc.,  jia-ss  over  and  affect  the 

child.  ^lethylene-blue  given  to  the  mother  in  the  last  ^'ZjT'  ""^  >  ■^■'7 
week  of  pregnancy  may  be  demonstrated  in  the  urine 
anil  feces  of  the  new-born  for  three  days  after  birth. 
Mo.st  antitoxins  go  to  the  child  through  the  placenta. 
Outside  of  these  transmitted  affections,  the  fetus  has  a 
l)athology  of  its  own.  It  will  be  imj)ossible  to  do  more 
than  mention  the  best  known  maladies. 

1.  General  fetal  dropsy;  general  cy.stic  elephanti- 
asis;  congenital  elephantiasis. 

2.  Congenital  microcephalus,  usually  with  idiocy; 
spastic  sjMnal  jiaralysis  (Little's  disea.se);  chorea,  Fried- 
reich's ataxia,  and  other  diseases  of  the  nerves. 

3.  Ichthyosis,  mild  and  severe;  hNpertrichosis; 
congenital  absence  of  |nitches  of  skin,  due  jirobably  to 
amniotic  adh(>sions.  Fio.  459.— Achondkoplisic Fetc- 

4.  Diseases  of  the  bones,  which  may  l)e  grouped  uu.hor-.  «p,^imen). 
under  the  general  term  "chonilroily-strojihia  fa'talis," 

but  are  otherwise   hardly  to  be  cla-ssified.     Some  ca.ses  resemble  rachitis;    some 
show  bone  aplasia.  h\'iioplasia,  or  irregular  hyperplasia. 

5.  Alxlominal  alYections:  peritonitis,  ascites  (which  may  Ix'  a  cause  of  serious 
dystocia),  congenital  stenosis  of  the  bile-ilucts,  hyjxTtrophic  stenosis  of  the  pylorus, 
and  neoplasms  of  the  liver. 

6.  Nephritis;  congenital  cystic  kidneys  (which  show  a  familial  tendency  and 
may  b(>  so  large  as  to  cause  obstruction  to  delivery) ;  dilatation  of  the  bladder,  with 
hypertrophy. 

7.  Circulatory  disea.ses:   endocarditis,  atheroma,  goiter. 

8.  Congenital  cataract,  iritis,  etc. 

9.  Congenital  uterine  prolap.st^  anil  injuries  to  the  child  from  without. 

A  minute  study  of  tiicse  conditions  would  ))e  well  repaid,  and  probably  would 
lead  to  the  discoverv  of  valuable  remedies  for  the  antenatal  treatment  of  the  diseases, 

635

THE  PATHOLOGY  OF  PREGNANCY,  LABOR,  AND  THE  PUERPERIUM 


or  at  least  a  recognition  of  sonic  of  the  causes  and  the  means  of  obviating  their 
action. 

The  Death  of  the  Mother.^Since  the  dying  mother  takes  oxygen  from  the 
fetus,  the  death  of  the  hitter  usually  occurs  first.  If  the  mother  dies  suddenly,  the 
child  may  live  for  a  variable  period.  Brotherton  reports  a  case  where  a  living  child 
was  extracted  twenty-three  minutes  after  the  death  of  the  mother,  and  Tarnier  one 
where  the  child  lived  twenty  minutes  after  the  death  of  its  mother,  who,  while  in 
the  Maternite,  was  killed  by  a  stray  bullet  tluring  the  Commune  (Polk). 

Rigor  mortis  may  occur  in  utero  (Fig.  460),  and  probably  is  common,  though 
rareU'  observed  and  still  more  rarely  published.     It  affects  fetuses  of  all  ages,  be-

Delivery  of  the 


gins  from  a  few  minutes  to  as  late  as  five  hours  after  fetal  death,  may  be  total  or 
partial,  and  may  cause  difficulty  in  delivery.  Its  pathology  is  identical  with  that 
of  rigor  mortis  of  the  adult  and  is  due  to  the  presence  of  lactic  acid  and  colloid  im- 
bibition of  the  muscular  fibers  (Meigs).  Curiously,  the  heart  may  beat  a  few  times 
even  after  rigidity  of  the  body  has  developed.  Rigor  mortis  is  found  more  fre- 
ciuently  in  cases  of  prolonged  labor,  eclampsia,  hemorrhage,  and  slow  asphyxia.  It 
i.-5  not  a  sign  that  the  child  was  delivered  alive — a  point  of  extreme  importance  in 
mechcolegal  cases.     (See  Paddock,  Wolff.)

CHAPTER  XLV 

TERATOLOGY 

For  details  of  this  subject  the  reader  is  referred  to  works  on  pathology.  Only 
the  barest  outlines  of  classification  and  a  few  principles  of  treatment  can  here  l>e 
given.     (See  Birnhaum,  Schwalbe.) 

Classification. — Congenital  deformities  are  not  rare.  A  child  born  with  a  de- 
formity so  marked  that  it  interferes  with  the  general  or  local  development  of  the 
body  is  called  a  monster.  Monsters  often  die  in  the  early  formative  stage,  which 
may  l)e  proved  l)y  an  inspection  of  al)orted  ova,  and,  if  deliveretl  alive,  they  usually 
succumb  within  a  few  hours  or  days,  being  incapable  of  extra-uterine  existence.  The 
frequency  of  monsters  in  aborted  ova  is  noteworthy. 

Of  monsters  there  are  two  cla.sses^single  and  double.  We  tlistinguish  three 
general  varii'ties  of  single  monsters  (Clurlt): 

1.  Monstra  jjer  defectum — where  all  or  part  of  an  organ  is  missing. 

2.  ]Monstra  per  fabricam  alienam — where  an  organ  is  wrongly  formed  or  dis- 
placed. 

3.  Monstra  i)er  excessum — where  an  organ  is  enlarged  or  duplicated. 

Causation. — Recent  experimental  work  has  done  much  to  clear  up  the  causa- 
tion of  monstrosities,  and  it  is  (juite  certain  that  external  agencies  have  much  to  do 
with  their  formation.  Heredity  has  indubitable  influence,  since  we  see  the  same 
peculiarity  in  several  generations  or  members  of  the  family.  Sometimes  a  genera- 
tion is  skipped,  and  the  ileformity  reai)pears  in  the  third — atavism.  We  do  not  yet 
understand  these  internal  causes,  and  for  want  of  a  better  term  they  are  called 
germinal,  since  they  are  inherent  in  the  ovum.  That  the  sperma  has  some  in- 
fluence in  the  production  of  monstrosities  is  rendered  plausible  by  the  experiments 
of  Bardeen,  who  saw  deformed  ova  result  from  fertilization  by  the  speniia  of  toads 
which  hatl  been  exposeil  to  the  x-ray. 

Of  external  causes  may  be  mentioned  injury  to  the  abdomen  or  uterus,  short 
of  the  actual  destruction  of  the  fetus  or  ovulum;  diseases  of  the  chorion  (Mall)  and 
of  the  amnion;  abnormal  implantation  of  the  ovum,  for  example,  in  the  tul)e  (Mall); 
arrest  of  develojiment,  and  changes  in  the  ovum  during  the  blastula  or  morula 
stages,  the  result  of  thermic,  chemical,  or  other  jihysical  action.  It  has  U'en  proved 
that  lithium,  sodium,  potassium,  and  magnesium  have  a  sjX'cial  selective  action  on 
the  various  cells  of  the  morula,  and  produce  characteristic  monsters,  some  of  the 
poisons  affecting  the  nervous  system  and  others  the  heart.  Stockard  and  Lewis 
protluced  .50  per  cent,  of  cyclojiean  monsters  from  the  eggs  of  the  common  miimow 
by  treating  them  with  solutions  of  magnesium  chlorid.  Hertwig  suggests  that 
perhaps  chemical  poisons  circulating  in  the  maternal  blood  may  affect  the  young 
embryo  and  cause  monsters,  a  theory  which  the  author  has  held  for  many  years. 
Nowadays  few  jiractitioners  and  none  of  the  scientists  believe  the  old  notion  that 
the  mental  state  of  the  mother  has  a  direct  influence  on  the  development  of  the 
child,  but  many  careful  oljservers  are  convinced  that  shock,  worry,  deprivation, 
etc.,  may  produce  vascular  and  nutritional  disturbances,  general  and  local,  in  the 
endometrium,  which  may  seriously  afTect  the  growth  of  the  ovum,  a  |X)sition  which 
the  author  has  long  held,  and  Ballantyne,  oneof  our  most  authoritative  teratol<)gi.>;ts, 
also  holds.

of  the  iiii'dullary  canal  to  early  hydrocephalus  or  liydrorachi.s,  or  to  a<lh<'!sion  of  the  dflic:in-, 
newly  formed  medullary  canal  to  ihe  amnion.  The  deformities  re-sulting  fnjm  thi.s  are  nr<jiiix*<l 
under  the  name  "craniora<hi.schi.sis."  The  .sjjlittinK  may  be  partial,  either  involving  only  the 
cerebral  vertebra-,  when  we  have  cranioschisi.s,  or  only  the  spin*.' — rachi.schi.si.s.  If  all  the  Htruc- 
tures  covering  the  medullary  canal  are  mi.s.sinn,  the  back  presents  a  snux^th,  shining  Kro<jve, 
with  or  without  traces  of  brain  or  spinal  cord  (Tins.  401  and  402).  If  (jnly  the  bony  arch  is 
mi.ssinjc,  we  have  a  meningocele,  or  hernia  cerebri,  hernia  si)inalis,  or  spina  bifida. 

When  there  is  a  mass  of  brain,  more  or  less  larne,  we  call  the  condition  acrnnia;  when  all  the 
brain  is  mi.ssing,  arienccp/ialus.  If  the  cranium  is  clo.sed  but  smaller  than  normal,  it  is  culled 
niicrocrphdhis. 

Irregularities  in  the  closing  of  the  branchial  clefts  produce  deformities  about  the  face  and 
neck,  the  simplest  of  which  are  harelip,  and  the  severest  may  show  absence  of  large  parts  of  the 
face. 

The  anomalies  resulting  from  deficiency  of  closure  of  the  lateral  plates  of  the  body  walls 
are  hernia  umbilicalis,  hernia  abdominalis,  ectopia  vesica*,  ectopia  cordis,  j'tc.  These  are  grouped 
under  the  name  "thoracogastro.schisis." 

The  splitting  may  go  .so  far  as  to  involve  the  intestine,  showing  that  the  two  layers  of  the 
celom  failetl  to  fuse.  Ab.sence  of  fusion  of  the  lateral  halves  of  the  genital  and  urinary  organs 
produces  deformities  here  of  utmost  variety.  Hypos|)adias  is  the  mildest  and  most  common, 
ectopia  vesica'  with  sjjlit  pelvis  more  marked,  ileformity. 

Agenesis  of  the  exfn'inities,  fusion  of  the  extremities  or  of  fingers  and  toes,  and  deformities 
due  to  amniotic  bands  occur,  but  are  rare.  If  the  anterior  cerebral  vesicle  does  not  divide,  we 
have  a  cvc1(jj)S  developed,  or  a  cijclocephaltts.  Cyclops  nujnsters  are  among  the  easiest  to  produce 
artificially  (I'ig.  404). 

2.  Mon.strn  per  fnhricam  nliennm  are  mainly  ca.ses  of  situs  inversus  vi.scerum,  abnormal 
position  of  the  kidneys,  testicle,  colon,  and  sometimes  of  the  joints,  and  congenital  lu.xations  and 
<leformitir'S.     The.se  latter  are  not  seldom  in  the  first  cla.ss. 

:i.  Moniilra  Per  PJxcessum. — Increase  in  the  number  of  a  part  or  organ  and  increa.se  in  the 
size  of  .same. 

Double  Monsters. — Monstra  duplica  come  from  one  ovum,  and  are  developed 
from  one  jicrminal  vesicle.  Two  germinal  spots,  two  primitive  streaks,  or  two 
medullary  grooves  may  he  formetl,  or,  later  in  gro\\'th,  a  duplication  of  one  or  the 
other  end  of  the  germinating  zone  takes  place.  E.xperiments  have  shown  that 
double  monsters  can  be  produced  in  the  blastula  stage  by  separating  the  blast omeres, 
which  is  accomplished  mechanicallj'  or  chemically.  If  two  embryonal  areas  appear, 
it  is  possible  that  two  complete  individuals  (homologous  twins),  or,  if  the  two  areas 
are  not  entirely  separated,  unitcMl  twins,  will  result.  If  the  two  areas  are  uneciual 
in  size,  one  of  the  individuals  is  stunted  and  attached  as  a  parasite  to  the  other,  or 
may  be  included  in  the  other.  The  etiology  of  such  monstrous  formations  is  un- 
knowTi.  Entrance  of  more  than  one  spermatozoid  into  the  ovum  is  not  the  cause, 
because  eggs  so  impregnated  usually  die.  Kohlbriigge  has  shown  that  in  some 
animals  the  accessory  sj)ermato/-oids  supjily  food  for  the  germinating  ovum. 
Whether  there  is  a  s|ilitting  of  one  primitive  streak  or  the  fusit)n  of  two  primarily 
developetl  is  unknown — prol)ably  fission  occurs.  Double  monsters  are  thus  dassihed 
(Foerster). 

Tcrata  Katfididi/ma. — In  these  beings  the  fission  or  <loubling  is  from  the  head 
downward,  in  the  most  fully  develoi)ed  siwcimens  there  being  one  pelvis  and  two 
legs,  the  trunks  being  separate  (Figs.  4()r>-409). 

Ternta  Anadidyma. — Here  the  splitting  is  from  l>elow  upward,  all  grades  being 
observed  to  the  last,  where  the  two  complete  botlies  are  attached  at  the  head  (Figs. 
470-473). 

Tcrata  kata-anndidynia,  the  fi.ssion  being  from  both  aluive  and  h«-low.  The 
bond  of  imion  may  be  very  broad,  extending  up  and  down  the  whole  venter  or 
dorsimi  of  the  two  children,  or  very  small,  the  ix)int  of  attachment  l)eing  at  the 
sternum,  the  abdomen,  or  the  sacrum.  Rotation  may  bring  the  two  Ixxlii^  into 
a  line,  as  in  the  John.son  twins  from  Wisconsin  (Figs.  474-47G). 

Homologous  twins  are  the  best  examples  of  the  last  class,  since  in  these  the

fission  of  the  two  streaks  was  complete.  If  the  development  of  the  two  individuals 
is  equal,  two  well-forincd  ehildrcn  result;  if  (jnc  is  stHjii^rr  than  th<'  (jther,  its  heart 
overcomes  that  of  the  otiicr.  which  later  shrinks  up  into  an  acanliacus.  De|)en<linK 
on  the  oritiinai  distribution  of  enihryonal  cells,  one  or  the  other  portion  of  a  fetus 
will  be  represented  in  tlie  acanliacus,  the  head,  the  trunk,  or  the  lower  extremities 
(Figs.  477  and  478).  Sometimes  all  or  a  part  of  a  primitive  streak  develops  inside 
the  other  embryonal  area,  and  thus  inclusicj  fcetalis  and  teratomata  result. 

Homoiojious  portions  of  the  two  individuals  are  almost  always  united,  and  we 
name  the  monster  after  the  location  of  the  union;  for  example,  when  it  is  at  the 
sternum,  slcrnopodus;  the  en.siform  appendix,  xiphopagus  (Siamese  twins);  at  the 
sacrum,  pijijopaquH  (the  Bohemian  sisters);    at  the  head,  craniopdgm,  etc. 

The  Clinical  Aspects  of  Monsters. — Since  single  monsters  are  more  common

than  (loul)le,  they  ])re.sent  greater  interest  to  the  accoucheur,  and.  further,  they 
produce  dystocia  more  frecjuently  because  they  more  often  tlevelop  to  maturity  and 
Ix'cause  enlargement  of  the  parts  is  so  often  met.  Hydroce|)halus,  anencephalus 
with  l)road  shoulders,  h<'rnia.s,  and  accunmlation  of  tiuid  in  the  body  cavities  are 
the  usual  conditions  found,  but  they  present  simple  i)roblems  of  treatment.  Double 
monsters,  curiously  enough,  are  frequently  ex|K'lled  spontaneously,  but  when  they 
do  give  rise  to  dy.stocia,  dangerous  and  most  complicateil  oiHTations  are  often 
needed  to  etVect  d(>Iivery. 

Diagnosis. — Even  before  labor  one  may  su-sjiect  theexi.stence  of  an  abnormally 
formed  child.  Hydrocephalus  could  be  diagnosed,  and  an  acephalous  mon.ster  too, 
if  the  examiner  were  on  the  alert.  .\  woman  who  had  delivered  one  of  the  latter 
was  nmch  relieved  when,  at  the  seventh  month  of  a  subse(|uent  pregnancy,  it  wa.s 
possil)le  to  assure  her  that  the  fetus  had  a  large,  well-form»'d  hea<l.  I'nder  the  same 
circumstances  the  absence  of  a  cranium  would  as  easilv  have  been  determinable. 


542  THE   PATHOLOGY   OF   PREGNANCY,    LABOR,    AND    THE    PUERPERIUM 

The  a:-ray  is  now  available.  Since  recurrence  of  monstrous  children  is  not  rare,  the 
history  is  of  service  in  the  diagnosis. 

During  labor  the  possibility  of  a  monstrous  formation  is  to  he  considered,  with 
other  things,  Avhen  the  internal  examination  reveals  atyjiical  findings.  Before 
attempting  cesarean  section  it  is  wise  to  consider  the  shape  of  the  child,  as  well  as 
its  size  and  viability,  for  it  might  be  humiliating  to  deliver  a  monster  b}"  this  serious 
operation.     It  has  happened  to  clever  accoucheurs. 

An  anencephalic  monster,  as  sho'yAii  in  Fig.  4G2,  presenting  by  the  head,  might 
easily  cause  confusion  with  i)la('enta  prtevia,  prolapse  of  the  cord,  simple  face  pre- 
sentation, or  lireech  presentation.  The  frequent  association  of  deformities  will 
help  in  diagnosis;  for  example,  when  in  a  breech  delivery  a  spina  bifida  is  found, 
hydrocephalus  may  be  expected,  or  if  the  delivered  head  shows  harelip  and  delay  in 
delivery  of  the  trunk  ensues,  one  should  think  of  a  monster,  single  or  double.  Poly- 
hydramnion  is  so  frequently  present  with  fetal  anomalies  that  one  should  always 
look  for  the  latter  when  it  exists. 

Double  monsters  have  never  been  diagnosed  before  labor;  at  most,  twins  have 
been  suspected.  Two  bags  of  waters  exclude  a  double  monster.  The  rule  has  Ijeen 
that  only  after  labor  stopped  was  the  obstruction  recognized  to  be  due  to  joined 
fetuses,  but  inspection  of  the  part  delivered  may  give  a  hint  as  to  the  cause  of  the 
delay,  for  example,  harelip  or  atresia  ani  (Lyell).  If  delay  in  delivery,  not  overcome 
by  the  usual  manipulations,  should  occur,  an  examination  with  the  half  hand  or,  if 
necessary,  ^vith  the  whole  hand,  is  to  be  made.  For  the  sake  of  deliberation  and 
thoroughness  an  anesthetic  had  best  be  given,  and  in  primiparse  a  deep  episiotomy 
is  advisable.  Such  an  exploration  must  decide  the  presence  of  enlargement  of  a 
part  of  the  fetus,  a  tumor  of  the  uterus  or  the  fetus,  a  double  monster,  and,  if  the 
last,  the  location  and  extent  of  the  area  of  fusion,  the  number  of  arms  and  legs,  and 
the  movability  of  one  child  on  the  other. 

Treatment. — Nature  helps  in  the  delivery  of  monsters  by  interrupting  the  pregnancy  while 
the  fetuses  are  still  small,  but  cases  are  on  record  of  united  twins  weighing  15  and  1732  pounds, 
causing  formidable  dystocia.  In  general,  breech  presentation  is  most  favorable  for  all  mon- 
strosities, and  if  duplicate,  it  is  best  if  all  three  or  four  legs  are  accessible.  Single  monsters  with 
enlargement  of  parts  are  to  be  reduced  in  size;  a  hydrocephalus  is  punctured  (never  forceps);  a 
full  abdomen  is  emptied,  etc.,  and  if  delivery  is  indicated,  version  and  extraction  are  preferable. 
No  consideration  is  to  be  shown  either  a  single  or  a  double  monster  when  the  mother's  life  is  in 
danger.  Since  the  necessary  mortality  in  labor  and  afterward  is  enormous,  all  our  efforts  should 
be  directed  to  saving  the  mother.  Experience  has  shown  that  it  is  best  to  deliver  the  children 
whole,  and  not  to  amputate  a  head  or  trunk  which  has  been  expelled.  It  may  be  necessary  to 
amputate  the  delivered  portion  in  order  to  gain  access  to  the  rest  or  to  render  the  balance  of  the 
mass  movable,  but  such  occasions  are  rare.  Extremities  should  not  be  removed,  because  they  do 
not  interfere  \\ith  our  manipulations;  further,  they  provide  a  grasp  on  the  locked-in  fetuses,  and, 
thirdl}%  their  removal  destroys  the  relations  of  one  twin  to  the  other  and  adds  complications  in  the 
diagnosis  and  treatment.  Cesarean  section  may  be  necessary  if  attempts  at  delivery  from 
below  fail,  but  it  has  very  rarely  been  done — indeed,  the  patients,  when  they  come  to  this  point, 
are  the  poorest  possible  subjects  for  abdominal  delivery.  Contracted  pelvis,  as  a  complication, 
would,  of  course,  indicate  it,  and,  too,  if  a  double  monster  were  recognized  at  a  time  when  an 
abdominal  operation  could  be  performed  under  ideal  conditions — an  occurrence  not  yet  on  record. 

For  clinical  purposes  the  various  double  monsters  may  be  divided  into  three  forms,  as 
follows  (Vcit): 

1.  Those  which  offer  obstacle  to  delivery  by  the  increase  of  the  size  of  the  body  at  one  or 
the  other  end;  for  example,  diprosopus,  cephalothoracopagus,  dipygus  parasiticus — such  as  an 
epignathus.  ]\Iost  of  these  monsters  belong  to  the  classes  terata  anadidyma  and  terata  katadi- 
dyma  (Figs.  46.5  to  473) . 

2.  Those  monsters  where  fusion  is  at  one  or  the  other  end,  the  two  having  a  tendency  to 
form  a  straight  trunk — ischiopagus,  pygopagus,  craniopagus. 

3.  Where  the  monsters  are  well  formed  and  have  freedom  of  motion  at  the  point  of  fusion, 
for  example,  thoracopagus,  xiphopagus,  or  where  there  are  two  or  three  heads,  well  developed, 
on  one  trunk. 

In  the  first  class,  if  the  two  heads  present  and  engage,  one  after  the  other  is  delivered  by 
forceps;  if  not  engaged,  version  is  performed,  then  exenteration  and  craniotomy  in  succession,  if 
necessary.  If  one  head  is  delivered  and  the  shoulders  do  not  ('om(>,  the  deliAcrcd  head  may  have 
to  be  amputated,  by  which  access  is  gained  to  the  double  trunk.  The  second  head  is  led  into  the 
pehas,  delivered,  and  then  the  double  trunk  reduced  in  size  by  cleidotomy  and  exenteration. 
If  the  duplicity  is  caudal,  all  four  extremities  are  to  be  delivered  at  one  time,  and  evisceration  of 


TERATOLOGY  543 

the  trunks  performed,  after  which  the  extraction  of  the  common  shoulders  and  head  is 
simple. 

The  second  chiss  of  monsters,  united  by  the  head  or  breech,  S4-ldotn  c-ausi-s  trouble,  the 
lonK,  sau.sajie-shafM'd  trunk  slii)i)inn  tliroujih  with  no  (lifhculty.  Hoot  and  Hartlctt,  of  Chicago, 
found  an  i.schiopanus,  bent  like  the  letter  U,  with  the  two  fused  breeches  preuenting.  The  junc- 
tion wtus  severed  and  delivery  quickly  i'lTecte<l,  (jne  fetus  at  a  time. 

Of  the  third  chtss  of  cases,  the  Siamese  twins  are  a  good  example.  One  of  these  was  deliv- 
ered by  the  liead,  the  other  by  the  bre<'ch.  The  connecting  band  may  be  tm  ehusticas  to  allow 
version  of  the  .second  twin  after  the  delivery  of  the  first.  It  is  fortunate  if  the  two  children  pre- 
8<'nt  by  the  breech,  and  the  posterior  one  should  be  delivered  first,  then  tin- anterior  child.  If  the 
bond  of  union  is  hrmer,  by  une()ual  traction  the  head  i)(  the  posterior  fetus  is  to  be  cjrawn  int<i  the 
neck  of  the  anterior  and  both  delivennl  together.  Exenteration  will  Ik-  done  or  the  l>ond  of  union 
severed  whenever  neces.sary.  If  one  child  presenting  by  the  head  is  deliv«'n'<l  to  the  trunk  and 
labor  stops,  the  other  may  be  turned  by  the  breech  and  the  two  then  deliveretl  sule  by  side.  If 
two  heads  present  and  neither  engages,  version  on  both  twins  is  jx-rfonnetl. 

As  a  rule,  the  oi)erator  is  not  re(iuired  to  hurry,  but  may  proceed  with  calmnes-s  and  delilx-r- 
ation.  He  should  study  carefully  the  kind  of  mon.ster  he  has  to  deal  with,  its  size,  the  shajK-  and 
size  of  the  i)elvis,  etc.,  and  have  the  projjo.sed  procedures  lompletely  W(jrke<l  out  b«'fore  operating.

CHAPTER  XL VI 
DISEASES  OF  THE  FETAL  ENVELOPS 

THE  CHORION 
Clinically,  m^-xoma  diffusum  and  fibrosum,  which  pathologists  describe,  are 
of  httle  importance,  but  vesicular  degeneration  of  the  chorion  is  not  uncommon, 
and  requires  the  earnest  attention  of  the  accoucheur.  Hydatidiform  or  vesicular 
degeneration  of  the  chorion,  vesicular  mole,  or  grape-mole,  is  due  to  a  proliferation 
and  degeneration,  with  edema,  of  the  stroma  of  the  chorionic  villi  and  increase  of 
the  S3Tic}i:ium.     (See  Caturani,  Turazza.) 

Kossman  showed  that   Hippocrates  knew  of  this  condition,  and  ascribed  it  to  a  mucoid 
degeneration  of  the  viUi,  a  theory  which  Virchow  propounded  and  which  was  generally  accepted 

until  the  minute  and  convincing 
work  of  Alarchand  and  Frankel 
was  published.  Aetius  of  Amida, 
in  the  sixth  century,  described  it, 
and  Vega,  in  1.^64,  and  Valleriola, 
in  Turin,  in  1573,  reported  typical 
cases.  The  latter  believed  the  dis- 
ease to  be  due  to  abnormal  devel- 
opment of  the,  at  that  time,  de- 
scribed "female  semen."  The 
vesicles  were  considered  "bladder 
worms,"  "pseudohelminths,"  or 
Acephalocystis  racemosa  (Clo- 
quet,  1822).  Velpeau  (1827)  called 
the  cysts  degenerated  villi,  as  we 
now  know  them  to  be;  Meckel 
(1847)  showed  the  hjqjerplasia  of 
the  connective  tissue  with  edema, 
and  Virchow  (1853)  called  it  a  mu- 
coid or  myxomatous  degeneration. 

A     hydatidiform     mole 

cannot  be  mistaken  (Fig. 
479).  It  resembles  a  bunch 
of  Catawba  grapes  of  most 
irregular  size,   varying  from 

Fig.  479. — Hydatidiform  Mole  (Author's  Specimen).  that  ot    a  piU-hcad  tO  that  01 

a  hen's  egg  (rare),  but  usu- 
ally the  size  of  a  pea  or  bean.  A  loose  mass  of  thick  decidua,  and  cheesy  cellular 
material  with  blood-clots  interspersed  with  these  bladder-like  bodies,  is  usually  de- 
livered, but  the  specimen  may  be  a  compact,  egg-shaped  cast  of  the  uterus,  fibrous, 
and  filled  with  vesicles.  In  these  cases  the  gro^^'th  had  ceased  some  time  prior  to 
expulsion.  The  vesicles  hang  to  parent  stems  and  to  each  other  (Fig.  480).  Ordin- 
arily, all  traces  of  fetus  and  amnion  have  disappeared,  but  cases  are  on  record  where 
both  have  been  preserved,  and  then  the  mass  may  be  expelled  entire  and  be  covered 
by  decidua.  All  the  chorion  may  be  changed,  which  is  the  usual  finding,  and  means 
that  the  degeneration  began  early  in  gestation,  but  either  the  chorion  frondosum  or 
the  chorion  Iseve  may  be.  alone  affected.  Even  parts  of  the  placenta  may  be  intact, 
and  a  living  child  may  be  born,  or  only  one  ovum  of  a  t^\^n  pregnancy  may  be  thus 
degenerated,  as  in  the  case  of  the  famous  anatomist,  Beclard,  whose  mother,  at  the 
fifth  month  of  gestation,  expelled  hydatids  (Parvin).  The  case  of  Depaul  was 
similar.     Ectopic  gestation  may  undergo  this  form  of  degeneration.     It  is  not

certain  whether  the  degenerati(m  precedes  the  death  of  the  child  or  follows  it — 
probably  both  occur.  The  author  has  frecjuently  found,  in  ab(jrt<-d  ova,  one  or 
more  villi  degenerated  and  fonning  vesicles. 

iMicroscopically,  the  stroma  of  the  villi  is  hyperplastic,  and  has  become  edema- 
tous ami  necrotic,  so  that  only  at  the  jMTiphery  of  the  vesicles  can  the  fibrillary 
structures  and  cells  be  distinguished  (Fig.  481).  Very  few  ves-sels  can  be  found, 
antl  these  are  empty.  Particularly  marked  is  the  proliferaticjn  of  Langhans'  layer, 
which  may  inva(h'  the  syncytium  and  grow  into  the  intervillcjus  sjjacc's.  Its  cells 
are  enlarged  and  degenerated,  staining  badly.  The  syncytium  also  hypertrophies 
and  undergoes  necrosis,  it,  as  well  as  Langhans'  layer,  showing  numerous  vacuoles. 
This  process  may  be  so  marked  that  the  syncytium  may  grow  through  the  decidua 
into  the  uterine  musculature.  Even  the  vesicles  may  burrow  into  the  veins  and 
between  the  muscle-fibers,  sometimes  as  far  as  into  the  peritfjneal  cavity,  causing 
peritonitis  and  i)eritoneal  hemorrhage.  If 
the  uterine  wall  is  honey-combed  by  the  ad- 
vancing growth  of  the  proliferating  villi,  it 
may  ru])ture  during  the  ])rocess  of  abortion, 
or  l)e  jjunctured  by  tlie  finger  or  instruments, 
or  the  woman  may  die  of  external  hemor- 
rhage because  the  disea.sed  uterus  cannot 
contract  properly.  These  forms  are  called 
destructive  moles,  and  clinically  are  nuidi 
feared. 

Special  mention  is  to  be  made  of  those 
destructive  hydatidiform  moles  which  even- 
tuate inchorio-epithelioma  or  malignant  syii- 
cytioma.  ^leckel.  Ix'fore  1795,  recorded  an 
instance  of  grape-mole  which  resulted  in  the 
woman's  death  by  metastases  of  a  tumor 
formed  in  the  uterus,  and  recently  it  has 
been  found  that  a  history  of  cystic  mole  is 
obt'.iined  in  over  half  of  the  cases  of  syncy- 
tioma  malignum  which  come  to  treatment. 

The  syncytioma  may  develop  in  the 
uterus,  in  the  cervix,  or  in  the  vagina  (local 
metastases),  or,  if  the  vesicl(>s  and  masses  of 
syncytium  are  carried  by  the  blood-stream 
to  distant  organs,  a  general  syncytiomatosis 
may  ensue,  but  usually  the  lungs  are  first  and 
most  involved.   Local  and  general  metastases 

may  t)ccur  while  the  grape-mole  is  still  in  the  uterus.  Since  so  many  ca-ses  t)f 
chorio-ejjithelioma  malignum  give  a  history  of  mole,  one  might  think  that 
the  hyilatiiliform  ilegeneration  of  the  chorion  was  very  freciuently  the  cause, 
but  it  must  be  rememberetl  that  grape-mole  is  not  verN-  infrecjuent,  and  that 
a  case  of  syncytioma  will  almo.st  always  l)e  published,  while  the  mole,  being 
so  much  more  conunon.  is  not.  For  example,  the  author  had  nine  ca.^^^  of 
vesicular  mole,  not  published,  and  none,  lus  far  as  known,  has  develoiH'd  metas- 
ta.ses.  Konig's  12,  (liglio's  13,  and  Kehrer's  oO,  followetl  up,  did  not  devt-lop 
chorio-epithelioma.  Unfortunately,  it  is  impossible  to  determine  when  a  given 
mole  will  b(>come  malignant. 

A  polycystic  degeneration  of  the  ovaries  has,  in  a  large  proiwrtion  of  cases.  l)e<'n 

found  coincident  with  this  condition,  an  obs(Tvation  made  by  de  Ciregorini  in  1795. 

Both  ovaries  may  l)e  changed  into  tumors  as  large  as  a  fist,  compo.sed  of  inunensely 

Droliferateil  and  sometimes  edematous  ovarian  stroma,  full  of  cysts  which  vary  in

size  from  a  few  millimeters  to  6  cm.,  and  which  are  lined  or  partl>'  filled  by  a  varie- 
gated layer  of  lutein  cells,  that  is,  the  ovaries  are  changed  into  lutein  cysts. 

While  the  two  conditions  are  often  associated,  we  cannot  draw  a  causal  con- 
nection between  them  nor  can  we  explain  their  frequent  coincidence. 

Etiology.— Muhiparse  are  oftener  affected  than  })rimiparff.  Such  moles  have 
been  found  in  women  fifty-two  and  fifty-three  years  of  age,  indeed,  the  frequency 
of  their  occurrence  after  thirty-five  is  remarkable  when  we  consider  the  smaller

number  of  births  at  this  period.  Molitor  records  the  birth  of  a  vesicular  mole  in  a 
girl  nine  years  old.  Syphilis,  heart  disease,  and  general  affections  have  no  direct 
l^earing,  but  the  association  with  nephritis  has  often  l^een  noted.  The  actual  ex- 
citing cause  of  the  degeneration  is  unknown,  and  probal)ly  several  exist.  It  is 
possible  that  the  ovum  is  primarily  diseased,  because  cases  are  on  record  of  one 
twin  Ix'ing  healthy,  the  other  changed  into  a  vesicular  mole,  and  secondly  aborted 
ova  often  show  a  mild  hydropic  disease  not  enough  to  cause  the  death  of  the  fetus, 


DISEASES    OF   THE    FETAL    ENVELOPS  547 

and  probably  secondary  to  the  latter.  The  ovarian  lutein  cysts  have  been  used  as 
an  argument  for  the  theory  of  the  (^vuhir  origin  of  the  mole.  Abnormal  secretion 
from  a  diseased  corpus  luteum  i)roduciiiK  a  diseased  (jvum  is  sufig^'^^ted  by  Fninkel, 
That  the  chan<rc  is  the  result  of  maternal  influences,  and  especially  an  endometritis, 
was  believeil  by  \'ircho\v  and  sui)ported  by  W'aldeyer,  \'eit,  and  Aiciiel.  The  latter 
exposed  the  uteri  of  pregnant  dogs,  injured  the  placental  site  by  pressure,  and  ol>- 
served  the  formation  of  hydatidiform  mole  in  7  of  13  exjx'riments. 

Diseased  decidua  is  usually  found  with  moles,  and  the  recurrence  of  the  alTee- 
tion  also  points  to  the  endometrium  as  the  cause.  One  woman  had  vesicular  moles 
in  11  pregnancies  and  another  in  4,  while  the  latter's  husband  had  a  healthy  child 
by  another  woman.  Probably  endometritis  will  explain  most  cases,  and  we  know 
that  the  nutritional  conditions  of  the  placental  site  are  vitally  important  to  the 
health  of  the  ovum.      (See  Marchand,  Iloerman.) 

Clinical  Course. — Enlargement  of  the  uterus  faster  than  is  consistent  with 
normal  pregnancy,  and  atypical,  irregular,  uterine  hemorrhages,  are  the  two  most 
I)romin<'nt  symptoms.  Serous  or  sanguineous  discharges  may  persist  in  the  interval, 
and  exceptionally  hemorriiage  may  not  occur  until  al)ortion  begins.  All  my  pa- 
tients were  ill,  complaining  of  pain  in  the  lower  abdomen,  general  weakness,  and, 
when  the  floodings  were  profuse,  showing  the  effects  of  anemia.  Two  women  were  al- 
buminuric and  edematous  up  to  the  hips,  and  one  had  hyperemesis  gravidarum.  In 
the  latter  case,  during  the  therapeutic  aborti<jn,  undertaken  for  the  cure  of  the  p<'r- 
nicious  vomiting,  the  vesicular  mole  was  discovered,  no  bleedings  having  precedetl. 
All  my  other  cases  except  one  terminated  in  abortion  before  the  sixth  month,  and 
in  the  one  the  mole  ceased  growing  and  was  expelled  at  term.  Depaul  and  Madden 
had  ca.ses  which  went  over  term. 

Exj)ulsion  of  the  vesicular  masses  is  usually  complete  when  once  started; 
rarely  does  only  one  vesicle  or  cluster  escape.  Hemorrhage  is  always  marked  during 
the  abortion  unless  growth  has  ceased  and  the  mass  has  become  shrunken  and  dry. 
Death  from  acute  anemia  is  not  rare.  In  my  experience  the  blood  has  been  of  a 
lighter  red  than  normally  and  showed  less  tendency  to  clot.  Uterine  action  is 
sluggish,  the  al)ortion  sometimes  dragging  on  for  days,  and  contraction  and  retract- 
tion  of  the  organ  unsatisfactory  after  it  is  once  emptied.  Destructive  moles,  where 
the  proliferating  syncytium  and  vesicles  burrow  into  the  uterine  wall,  or  even 
through  it  into  the  peritoneal  cavity,  causing  intraperitoneal  hemorrhage,  are  very 
rare,  but  the  possibility  of  a  weakened,  honey-<-ombed  nuisculature  giving  way  under 
the  finger  or  curet  is  always  to  be  borne  in  mind.  Sepsis  seems  to  be  favored  by 
hydatidiform  ukjIc.  Occasionally  purplish  tumors  are  fountl  on  the  cervix,  in  the 
vagina,  or  about  the  vulva,  which  on  section  show  syncytium,  blood,  and  degenerated 
villi.  These  usually  occur  after  the  uterus  is  emptied,  but  may  be  found  coinci- 
dent with  the  mole,  and  are  probably  local  syncjlioma  metastases.  They  are 
generally  benign  (ride  infra.). 

Diagnosis. — Rapid  growth  of  the  uterus,  atypical  uterine  hemorrhages,  al>- 
sence  of  fetal  movements  and  of  a  fetal  body  on  palpation,  a  soft. elastic,  not  doughy, 
feel  of  the  ut(>rus,  and  the  general  evidences  of  illness  allow  the  accoucheur  to  make 
astnmg  a.ssumi)tion  of  the  presence  of  a  vesicular  mole.  Rarely  d(K's  a  jiiece  of  it 
escape,  but  here  the  diagnosis  would  be  i)ositive.  and  the  same  may  be  said  if  the 
mole  is  felt  through  the  cervix.  -\  vaginal  metastasis  will  indicate  a  mole  in  the 
uterus.  In  the  differential  diagnosis  polyhydranmion  might  l)e  con.sidered  when 
the  distention  of  the  ut«'rus  is  acute  and  great,  and  graiM'-Iike  sarcoma  of  the  cervix 
if  part  of  the  tumor  should  hang  out  of  the  uterus.  In  two  of  my  cases  the  uterus 
got  smaller,  not  larger,  before  the  mole  was  ex|K'lletl. 

Prognosis. — In  ver>'  rare  instances  is  the  chiUi  vial)le.  which  means  that  only 
part  of  the  chorion  is  involved.  The  rule  is  that  the  fetus  dies  early  and  is  al>- 
sorlx^d.     Combining  the  statistics  of  Dorland  and  Gerson,  Hirtzman,  and  William- 


548  THE    PATHOLOGY   OF   PREGNANCY,    LABOR,    AND    THE    PUERPERIUM 

son.  Ave  find  a  maternal  mortality  of  19  per  cent.  One  of  my  9  cases  died  from  acute 
sepsis.  The  dangers  are  uncontrollable  hemorrhage,  perforation  of  the  uterus 
(spontaneous  and  instrumental),  infection,  which  is  quite  conunon,  and  the  develop- 
ment of  sj-ncytioma  malignum. 

Treatment. — As  soon  as  the  diagnosis  is  made  the  uterus  must  be  emptied. 
Dilatation  of  the  cervix  sufficient  to  admit  two  fingers  is  necessary,  and  should  be 
obtained  by  cervical  tamponade  with  gauze  or  a  small  colpeurynter.  (See  Chapter 
LXIX.)  A  firm  vaginal  pack  of  sterile  cotton  should  be  inserted  as  a  safeguard 
against  hemorrhage  while  the  os  is  being  dilated.  At  the  time  of  operation  all  prepara- 
tions should  have  been  made  for  hemorrhage  and  the  treatment  of  anemia.  Curets 
and  placenta  forceps  should  never  be  used  l^ecause  of  the  danger  of  perforating  the 
uterus  whose  walls  may  have  l)een  weakened  by  a  destructive  gro\Ni;h.  Even  the 
fingers  may  perforate  the  thinned  uterus,  all  of  which  should  warn  to  caution,  yet 
every  safe  effort  is  to  be  made  to  remove  all  the  masses,  thus  to  eliminate  the  danger 
of  the  development  of  a  neoplasm  and  of  sepsis.     As  in  placenta  prsevia,  blood  must 

be  spared  at  every  move 
and  the  uterus  firml}^  tam- 
poned if  it  shows  a  ten- 
dency to  relax  and  bleed. 
Findley  advises  curetment 
after  several  weeks  to  as- 
sure the  cure,  but  this  is 
seldom  feasible.  Certainly 
the  woman  is  to  be  kept 
under  close  observation 
for  two  j'Cars,  and  the 
uterus  removed  if  signs  of 
a  malignant  tumor  de- 
velop in  it.

and  he,  therefore,  called 
the  tumor  sarcoma  de- 
ciduocellulare.  Since  then  over  300  cases  have  been  reported,  and  a  mass  of  liter- 
ature on  the  subject  has  accumulated.  Only  recently  have  our  ideas  regarding  the 
nature  of  the  affection  crystallized,  and  the  confusion  which  existed  may  be  ap- 
preciated after  a  glance  at  the  names  which  have  been  suggested  for  it — sarcoma 
deciduocellulare,  carcinoma  syncytiale,  deciduoma  malignum,  blastomo-deciduo- 
chorion-cellulare,  sync}i;ioma  malignum,  invasive  placental  polyp,  chorion  epithe- 
lioma. ]Marchand's  views  of  the  nature  of  the  tumor  are  now  generally  accepted, 
and  the  name  Frankel  and  Pick  proposed,  chorio-epithelioma,  is  the  one  most 
employed.  Frankel  first  called  attention  to  the  chorio-cpithelial  nature  of  the 
growth.     (See  Vcit,  Frank,  Ewing.) 

Chorio-epithelioma  is  a  tumor  developed  from  the  fetal  ectoderm,  which  may 
begin  during  pregnancy  (normal  or  abnormal)  or  after  the  uterus  is  emptied,  and 
which  is  characterized  by  exuberant  growth,  early  and  extensive  local  and  general 
metastases,  and  rapid  cachexia,  often  combined  with  sepsis. 

Its  causation  is  unknown.     We  know  that  syncytium  has  invasive  power,  that 


DISEASES   OF   THE    FETAL    ENVELOPS  549 

the  villi  erode  their  way  into  the  uterine  wiill,  into  the  blood-vessels,  but  what  keeps 
this  power  in  normal  limits  and  what  permits  the  growth  of  the  cells  to  pass  all 
binmds  cannot  even  be  conjectured.  Hydatidiform  mcjle  preceded  the  develop- 
ment of  this  disease  in  over  half  (jf  the  cases,  which  shows  that  some  connection 
exists  between  the  two. 

Pathology. — The  growth  begins  at  the  placental  site  and  protrudes  into  the 
uterus  as  a  very  vascular,  soft,  purplish  mass,  usually  sharply  differentiated  from 
the  mucosa.  It  may  grow  througii  th«'  uterine  wall  and  make  tumors  which  pro- 
ject into  the  peritoneal  cavity  or  the  broad  ligaments.  More  often  the  veins  are 
invaded,  antl  thus  general  metastases  brought  about.     Vaginal  metastases — the

most   frequent — are  probably   local,   from  surface   imjilantation.     In   apix'arance 
such  a  nodule  resembles  a  hematoma. 

Microscoi)ically,  the  tumor  is  made  up  of  ma.^M-s  of  syncytium  and  proliferated 
Langhans'  cells,  which  often  form  blood-spaces,  anil  even  structures  which  res<'mble 
villi.  Round-cells  and  polynuclear  leukocytes  al>ound;  the  whole  tumor  is  ver\' 
bloody.  Ma.sses  of  syncytium  may  be  seen  atlvancing  in  the  veins,  and  if  hydatidi- 
form mole  wa.s  present,  hydropsically  degenerated  villi  may  l>e  found.  Marchand 
distinguished  an  atypical  and  a  typical  variety,  l>t»th  «'(|ually  pathogenic,  but  in  the 
latter  the  tumor  cells  resembled  exactly  the  chorionic  cells  of  early  pn'giumcy.  The

altered  Langhans'  cells  (Fig.  483).  Sometimes  one  kind  of  cells  predominate  and 
again  the  other.  Combined  forms  exist.  Lutcnn  cysts  of  the  ovaries  develop  in  a 
large  proportion  of  the  cases  of  sync}i;ioma,  as  in  vesicular  mole. 

Curiously  enough,  malignant  chorio-epithelioma  with  all  its  characteristics, 
even  with  structures  resembling  villi,  has  been  found  to  arise  from  teratomata  of 
the  testicle.  It  probably  originates  from  fetal  ectoderm,  included  in  the  congenital 
teratoma. 

Clinical  Course. — After  an  abortion,  especially  of  a  vesicular  mole,  or  after 
labor,  the  patient  complains  of  irregular  uterine  hemorrhages.  Usually  a  curetage 
is  performed,  but,  since  the  masses  thus  obtained  resemble  placental  tissue,  a  mi- 
croscopic examination  is  often  omitted.  In  half  of  the  cases  a  vulvar  or  vaginal 
nodule  first  drew  attention  to  the  condition,  and  in  my  case  the  uterus  enlarged 
enough  to  be  felt  by  the  patient.  The  growth  may  be  found  during  pregnancy, 
before  expulsion  of  the  mole,  as  early  as  a  week  after  delivery  (Williams'  case),  but 
usually  several  months  later,  and  in  three  cases,  two,  three  and  one-half,  and  four 
and  one-half  years  after  delivery  (Krosing),  at  a  time  when  the  causal  gestation  had 
been  almost  forgotten.  Repeated  hemorrhages  rapidly  exhaust  the  woman,  weak- 
ness and  the  symptoms  of  anemia  become  pronounced,  pallor,  subicterus,  albumin- 
uria, edema  of  the  feet,  and  puffiness  of  the  eyes,  that  is,  the  signs  of  cachexia,

supervene,  and  very  often,  since  the  tumor  masses  in  the  uterus  possess  such  a  ten- 
dency to  necrosis,  a  vaginal  discharge  with  gangrenous  odor  and  general  septicemia 
with  fever  occur.  Metastases  in  the  lungs  may  be  diagnosed  when  cough,  bloody 
expectoration,  and  pulmonary  findings  are  present.  Examination  of  the  sputum 
has  thus  far  been  negative.  Metastases  occur  in  the  lungs,  vagina,  liver,  spleen, 
and  brain.     Vaginal  tumors  may  eat  into  the  bladder,  like  cancer. 

Prognosis. — Later  writers  distinguish  a  less  malignant  type  of  chorio-epithe- 
lioma, one  that  disappears  spontaneously  or  after  the  removal  of  the  vaginal  metas- 
tases and  uterine  curetage.  As  a  rule,  however,  unless  early  operation  is  performed, 
these  patients  die  within  a  year  after  the  first  appearance  of  the  neoplasm.  This 
is  the  most  rapidly  destructive  growth  with  which  we  have  to  deal. 

Death  occurs  from  intractable  hemorrhage,  cachexia,  infection,  septicemia, 
and  occasionally  from  hemorrhage  into  the  peritoneal  cavity  or  peritonitis,  both 
the  result  of  perforation  of  the  uterus  by  the  invading  tumor. 

Diagnosis. — Repeated  hemorrhages  after  abortion  are  usually  due  to  a  pla- 
cental polyp.  Curetage  is  indicated,  and  the  scrapings  should  be  studied  by  a 
competent  pathologist.  Recurrence  of  a  uterine  growth  after  successful  curetage 
for  removal  of  the  products  of  gestation  is  often  due  to  chorio-epithelioma.  A 
vaginal  metastasis  will  usually,  but  not  always,  indicate  the  cause  of  the  symptoms. 
Removal  of  part  of  the  tumor  and  its  microscopic  study  are  essential  for  positive

diagnosis,  which  an  expert  pathoUjgist  can  readily  make.  At  some  point  in  the 
section  the  characteristic  syncytial  formations  will  he  found.  In  the  difTerential 
diagnosis  fibroids,  other  neoi)lasins,  and  jx-lvic  exudates  must  be  considered. 

Treatment.-^  In  view  of  the  treacherous  nature  lA  the  disease  and  its  enormous 
mortality,  ratlical  extirjjation  of  the  uterus,  adnexa,  and  acees.sible  meta.stas<'S  is 
indicatetl.  Since  it  is  propagated  along  the  veins,  it  is  well  to  ligate  the  vessels  as 
far  outward  as  possible. 

DISEASES  OF  THE  PLACENTA 

Variations  in  Shape. — \  :iri;iti()n.s  from  the  typical  roiiiul  shapo  of  tho  placenta  are 
common,  utnl  ucntrally  have  no  practical  Hinnilicant'c.  (.•^cc  p.  .">().  i  'I'lics*'  variationw  an-  due 
to  irregularities  in  the  nutritional  conditioiiH  of  the  uteru.s.  A  placenta  nc-sted  in  the  horn  of  t lie 
uterus  is  likely  to  Ix'  round  anil  show  a  luarniiial  rinn.  <  »ne  near  the  os  may  encircle  the  orifice 
in  a  horseshoe  form.  One  attached  at  the  side  of  the  uterus  may  spread  on  iKjth  anterior  and 
posterior  walls  and  he  hilohate,  etc.  Without  doul)t  the  placenta  may  l)e  hiwctetl  or  tri8«'cte<l  by 
white  infarct  formations,  and  I  believe  this  is  the  conunonest  caUB*'  of  inepular  shapes.

for  they  may  be  left  in  the  uterus  ami  n'lyc  rise  to  hemorrliane  and  Bej)8iB.  They  are  sur>- 
posed  to  be  due  to  -  (1)  The  development  of  some  of  tlie  villi  of  the  chorion  la-ve;  i'2)  to  cutting

enK  was  converted  into  thin,  membranous  pla<-ent.il  tissue.  Moderate  dej;rees.  that  is,  extensive 
thin  placenta-,  are  occasionally  observed,  but  are  usually  due  to  infarct  formation.  ThethicknosB 
of  the  placenta  is  in  inverse  proportion  to  its  .size. 

Heart  disease,  nephritis,  anemia,  diseases  of  the  uterus,  favor  abnonnal  development  of 
the  placenta,  and  also  make  patholoKic  changes  in  the  uterine  nmsculature,  .such  :us  hyaline 
degeneration,  which  in  turn  cau-ses  atonia  uteri,  even  rupture,  etc. 

Infarcts. — Nearly  every  placenta  will  show,  on  careful  inspection,  whitish, 
nodular,  hard  areas,  occupying  the  fetal  or  maternal  surface,  or  both,  and  varying

tion.  though  little  is  positively  known  on  this  ix)int.  The  tlilYerent  kinds  will  be 
considered  in  the  order  of  their  frequency.

THE  PATHOLOGY  OF  PREGNANCY,  LABOR,  AND  THE  PUERPERIUM 


1.  At  the  edge  of  the  placenta,  at  the  site  of  the  sulx'horial  dccidua,  a  more  or 
less  complete  white  ring  is  found,  which  varies  in  width  from  2  to  16  mm.,  and  in 
thickness  from  1  to  4  mm.  Sometimes  the  ring  is  raised  from  the  surface  and  the 
attached  meml)ranes  are  doubled  back  over  the  edge  of  the  placenta,  as  in  Fig.  485. 
This  is  called  placenta  circumvallata  or  nappiformis.  There  are  four  views  as  to 
the  manner  of  production  of  this  anomaly — (a)  The  placenta  is  located  in  a  tubal 
corner  of  the  uterus,  or  over  the  internal  os,  and  the  area  of  the  placental  site  grows 
more  rapidl}^  than  the  rest  of  the  uterus,  the  latter  constricting  the  former  at  their 
junction  (Fig.  485).  {b)  Owing  to  inflammatory  changes  in  the  decidua,  the  closing 
ring  of  Waldeyer  and  the  decidua  sulx-horialis,  whose  nutrition  is  precarious,  be- 
come necrotic,  and  temporarily  hinder  the  splitting  of  the  decidua  and  the  growth  of 


Fig.  4S6.  Fig.  487.

Shows  development  of  the  fold  in  membranes  (from  Bumm). 


the  placenta  in  this  direction,  (c)  Endometritis  causes  early  adhesion  of  the  reflexa 
to  the  vera,  and  changes  at  the  site  of  the  closing  ring  of  Waldeyer  prevent  the 
growth  of  the  placenta  in  the  marginal  reflexa,  the  placenta,  therefore,  splitting  the 
vera.  We  sometimes  find  that  the  cotyledons  extend  1  j^  inches  beyond  the  insertion 
of  the  membranes  (v.  Herff).  (d)  Hitschman  believes  that,  as  the  result  of  a  sudden 
diminution  of  the  liquor  amnii,  the  coverings  of  the  ovum  must  shrink,  and  natur- 
ally there  would  be  an  infolding  at  the  edge  of  the  placenta  (Figs.  486  and  487) 
(Funck,  Sfameni). 

Placentae  marginatse  and  circumvallatse  have  much  clinical  importance,  be- 
sides the  interest  which  attaches  to  the  endometritis  so  often  causative.  Early  in 
pregnancy  smaller  or  larger  hemorrhages  sometimes  occur,  and  abortion  is  not  in- 
frequent.    Tubal  corner  placentas  might  be  called  a  distinct  clinical  entity,  causing

pain,  blooding,  abortion,  prcniiiturr  labor,  puny  childron,  postpartum  hemorrhaKc, 
and  difficulties  in  diaf^nosis.  (Sec  Angular  Pregnancy,  p.  IV.H).)  In  placenta  niar- 
ginata  adhesicjn  of  the  membranes  is  very  c<jnuMon,  anil  the  placenta  may  Ije  de- 
livered naked  or  decrowned  of  its  membranes.  As  the  result  of  this  retention  hemor- 
rhage and  sapremic  fever  sometimes  ensue.  Abnormal  mechanism  in  the  third 
stage,  with  retention  or  adhesion  of  the  after-birth,  reipiin'S  the  introduction  of  the 
hand  in  the  uterus  oftener  tiian  with  normal  j)Iacentas. 

2.  On  the  fetal  surface  of  the  placenta  we  find  nodular  infarcts,  which  vary  in 
size  from  those  scarcely  visiljle  to  the  eye,  to  3  to  5  cm.  across  and  up  to  1  cm.  thick. 
The  smaller  ones  preponderate  and  may  be  bunched,  or  there  may  bea  thin,  nodu- 
lar layer  of  fil)rin  wliicii  covers  a  good  part  of  the  fetal  surface. 

3.  Some  infarcts  take  in  the  whole  thickness  of  a  cotyledon  and  may  involve 
one  or  more  of  them.  In  Kig.  4S8,  which  came  from  a  nephritic,  nearly  one-half  of 
the  placenta  was  involved  in  infarct  formations  in  various  stages  of  development.

Such  a  condition  may  comjiromise  the  nutrition  of  the  chiki,  which  is  bom  weak  and 
puny, or  if, as  often  happens  in  Hright's  disea.se, m(»re  than  half  of  the  area  is  involved, 
the  child  will  die.  Such  phicentas  are  likely  to  l>e  i)rematurely  detached  (abruptio), 
and  Fig.  402  shows  a  hemorrhage  causing  a  .separation.  This  last  form  of  infarct 
bears  the  most  resemblance  to  the  ("ohnheim  infarct;  the  other  two  can  hardly  Im' 
called  thus,  though  Ackerman  gave  them  the  title  "white  infarcts." 

In  general  there  are  three  views  as  to  their  cau.sation.  Ack«'rman  In-lieved  a 
peri-art«'ritisor  emlarteritis  exist etl  in  the  villi  and  produced  oblittTation  of  the  vessel 
lumen,  with  consecutive  necrosis  of  the  villus  stroma,  then  of  the  villus  wall,  and  con- 
se(pient  clotting  of  the  blood  in  the  adjoining  intervillous  spaces.  StetTeck,  von 
Franque,  and  many  investigators  JK'lieve  that  endometritis  and  decidual  overgrowth 
antl  con.se(|uent  necrosis  of  the  villi  with  fibrin  dt'position  are  the  cause.  Primar>' 
alterationortlf.s(|uamatioM  of  the  chorionic  epithelium,  which  is  lutt  abnonnal  in  the 
last  w»'eks,  causes  deposition  of  fibrin  and  infarct  formation,  according  to  Hitschman. 
It  is  probable  that  there  is  truth  in  all  these  theories,  and  that  the  first  explains  the 


554 


THE  PATHOLOGY  OF  PREGNANCY,  LABOR,  AND  THE  PUERPERIUM 


multiple  infarcts  on  the  fetal  surface;  the  second,  the  infarcts  on  the  maternal  side, 
and  placenta  marginata;  the  third,  the  microscopic  infarcts  made  up  of  necrotic 
ectodermal  cells  which  are  constantly  found  in  ripe  jjlacentas.  Perhaps  the  general 
vascular  changes  of  nephritis  are  also  present  in  the  newly  formed  placental  blood- 
vessels, and,  through  endarteritis,  obliterate  their  lumen,  causing  infarcts  and 
hemorrhages,  and  finally,  the  typical  albuminuric  placenta.  May  not  these  infarcts 
be  one  expression  of  a  toxemia? 

Microscopically,  we  find  circumscribed  areas  of  placental  tissue  which  have 
undergone  coagulation  necrosis  (Figs.  489  and  490).  In  the  advanced  stages  the 
whole  mass  is  changed  into  fibrin  with  only  traces  of  the  previously  existing  villi. 
Sometimes  there  are  evidences  of  obliterating  endarteritis  and  peri-arteritis,  and,

when  endometritis  existed,  large  numbers  of  decidual  cells  undergoing  necrosis  and 
even  small-cell  infiltration,  which  may  affect  the  villi,  will  be  found. 

Clinically,  infarcts  cannot  be  diagnosed,  but  their  existence  can  be  expected 
in  cases  of  nephritis,  heart  disease,  syphilis,  endometritis,  and  when  they  were  pres- 
ent in  previous  pregnancies.  Mention  has  been  made  of  the  fact  that  those  infarcts 
which  take  in  one  or  several  cotyledons,  may  reduce  the  oxygenating  area  of  the 
fetus,  and  also  the  nutritional  functions  of  the  placenta,  so  that  the  child  is  puny  or 
even  starved  to  death.  Cognizance  is  taken  of  this  fact  in  deciding  on  the  induc- 
tion of  premature  labor  in  nephritis.  Extensive  infarct  formation  is  often  asso- 
ciated with  adherent  membranes  and  the  retention  in  the  uterus  of  masses  of  thick 
decidua,  which  often  give  rise  to  annoying  oozing  after  the  third  stage  of  labor,  and 
even  severe  postpartum  hemorrhage. 

Hemorrhages. — No  structure  in  the  })ody  possesses  blood-vessels  as  friable  as 
those  of  tlic  decidua,  and  as  a  result  hemorrhages  are  not  rarely  found  in  it.     These 


DISEASES    OF   THE    FETAL    ENVELOPS 


555 


are  almost  always  in  the  serotina,  and  produce  a  varying  degree  of  separation  of  the 
pliiccnta.  Sometimes  they  lie  in  the  decidual  septa  Ix'tween  the  cotyledons.  (It  is 
n(jt  prol)able  tiuit  these  septa  are  of  fetal  origin. j  In  the  latter  instance  they  im- 
pose as  intraplacental  henujrrhages.  It  is  not  clear  to  the  author  how  bleeding  can 
take  place  into  the  intervillous  spaces.  They  are  hlood  sinuses  and  communicate 
freely  with  each  other,  so  that  a  sudden  increase  of  arterial  pressure  w(juld  Ix-  dis- 
tributed evenly  through  tlie  whole  placenta,  and  would  not,  asSeitz  believes,  cause 
the  blood  to  burst  into  the  surrounding  ti.ssues.  Another  form  (jf  placental  hemor- 
rhage comes  from  rupture  of  the  marginal  sinus,  already  referred  to. 

It  must  not  be  forgotten  that  a  hemorrhage  can  occur  in  a  red  or  white  infarct. 
Hemorrhages  have  also  l)een  observed  on  Ixjth  surfaces  (jf  the  placenta.  Organiza- 
tion of  the  clot  occurs,  and  it  is  j)ossible  to  trace  the  changes  through  the  stages  of —

periphery,  with  some  liquid  content,  to  i4)  through-and-through  hard  fibrous 
noduh'.      These  nodules  resemble  white  infarcts. 

The  cauises  of  these  hemorrhages  are  acute  and  chronic  c«)ngestion,  increased 
blootl-pressure,  stagnation  of  the  venous  blood-current,  di.si':ise  of  the  villi,  of  the 
decidual  blood-vessels  (endometritis),  and  the  l)lood  changes  incident  to  Bright's 
disease,  toxemia,  hemorrhagic  diathesis,  and  .-syphilis.  Physical  <»r  mental  shock 
and  local  injury  al.«^o  may  cause  them.  I  believe  there  is  some  relation  between  the 
toxemia  of  i)regnancv,  hemorrhages  in  the  (h'cidua,  even  abruptio  placental,  and  the 
hemophilic  conditions  which  ari.xe  during  gestation. 

Clinically,  placental  hemorrhages  are  of  great  importance.  If  they  occur  early 
in  pregnancy,  al)()rtion  may  result,  and,  perhaps,  fetal  monsters.  Later,  abruptio 
placenta*  may  ensue.     Smaller  clots  may  not  Ik*  found  until  after  delivery,  but  the

history  of  attacks  of  pain,  slight  external  bleeding,  and  uterine  contractions  which 
subsided  may  serve  to  show  the  accoucheur  that  some  disturbance  of  fetation  had 
occurred  at  some  time  during  pregnancy. 

Rarely  coagulation  of  the  blood  in  the  intervillous  spaces  takes  place.  Throm- 
bosis of  the  sinuses  of  the  placental  site  may  be  looked  upon,  in  the  later  weeks,  as 
a  normal  process,  and  preparatory  to  involution  of  the  uterus.  It  has  been  found 
as  early  as  the  second,  third,  and  fourth  month,  but  it  is  then  pathologic.  It  may 
overstep  the  bounds  of  the  normal  by  going  through  the  uterine  wall  into  the  veins 
of  the  broad  ligaments,  and,  especially  if  these  are  varicose,  may  lead  to  the  develop- 
ment of  phlegmasia  of  the  limbs,  both  before  and  after  delivery. 

Placentitis. — Older  wTiters  described  an  affection  of  the  placenta  which  we  now 
classify  under  infarcts,  but  there  does  seem  to  be  an  inflammation  of  the  chorionic 
villi  which  is  secondary  to  endometritis  {q.  v.). 

Edema. — An  edematous  placenta  may  resemble  a  syphilitic  one,  and  the  micro- 
scope may  have  to  decide.  The  villi  are  club-shaped  and  swollen,  with  irregular 
contour.     Usually  the  syphilitic  placenta  feels  fatty,  while  one  can  squeeze  water

from  the  edematous  placenta,  which  is  pale,  thick,  soft,  shagg}',  and  mushy,  with 
torn  serotina.  The  causes  are  maternal  and  fetal  heart  disease,  nephritis,  and 
general  anasarca  from  any  source,  polyhydramnion,  and  fetal  blood  diseases. 
Abortion  is  the  rule.  If  the  child  is  also  edematous,  formidable  dystocia  may 
result. 

Atelectasis. — Sometimes  a  placental  cotyledon  is  completely  infiltrated  with 
fibrous  material,  solid,  dark  red  in  color,  and  hard  to^the  touch.  It  occurs  occasionally 
in  placenta  prscvia,  the  piece  overlapping  the  internal  os  being  in  this  condition, 
and  it  may  make  the  diagnosis  difficult. 

The  fibrous  change  may  be  concrete,  or  may  be  somewhat  diffuse,  giving  the 
whole  placenta  a  fibrous  character.  It  may,  therefore,  interfere  with  the  nourish- 
ment of  the  fetus,  and  probably  has  a  pathology  analogous  to  that  of  white  infarct. 

Calcification. — Not  infrequently  the  serotinal  surface  of  the  placenta  is  strewn 
with  white,  sandy  deposits.  These  may  be  discrete  or,  rarely,  may  be  fused  to- 
gether into  little  plates  of  hard,  brittle  masses.  They  are  composed  of  calcium 
carbonate  and  phosphate  and  magnesium  phosphate,  lie  in  the  upper  layers  of  the 


DISEASES    OF   THE    FETAL    ENVELOPS  557 

decidua  serotina,  especially  around  the  "anchoring  villi,"  are  due  to  the  deposition 
of  the  salts  in  areas  which  had  undergone  fibrinous  degeneration,  and  are,  theref(»re, 
associated  with  white  infarcts;  they  have  no  clinical  significance,  arc  not  syi)hilitic, 
though  they  may  he  found  in  luetic  placentas,— usually  in  the  vessels'  wall,-  do 
n(»t  always  indicate  that  the  gestation  has  been  prolonged  (since  they  are  found  in 
abortions),  are  not  tubercular,  and  do  not  occur  with  especial  frequency  in  any 
particular  condition.  It  has  seemed  to  me  that  they  render  the  placenta  stiff, 
which  facilitates  its  separation  and  expulsion,  an<l  that  usually  no  piece  of  a  cal- 
careous placenta  is  retained. 

Cysts  of  the  Placenta. — Un  the  fetal  surface,  underneath  the  anuiion  and  just 
under  the  ehorial  membrane,  cysts  are  not  seldom  found.  They  vary  in  size  from 
the  mi<'roscopic  to  that  of  a  goose-<'gg,  and  are  oftenest  found  on  rifM'  {)lacenta«, 
but  have  been  noted  at  all  times  after  the  twenty-si'cond  week,  have  clear  yellowish 
or  cloudy  and  bloody  content,  contain  albumin,  mucin,  fat,  detritus,  and  various 
sotlium  and  chlorin  salts.  Often  a  white  infarct  is  found  underneath  the  cyst,  and, 
on  opening  the  latter,  the  lining  is  seen  to  be  of  soft,  whitish,  shaggy,  necrotic  ma- 
terial resembling  decidua.  This  is  generally  admitted  to  be  degenerated  Langhans' 
cells,  which  are  large,  hydropic,  with  a  big  nucleus  and  all  fatty  degeni'rated.  It 
is  believed  that  a  few  of  these  cysts  may  be  due  to  degenerated  decidua  or  the  end- 
products  of  large  white  infarctions  or  hemorrhages.  Clinically,  they  are  of  no  im- 
portance. If  a  large  marginal  cyst  ruptured,  one  might  think  the  bag  of  waters 
had  opened  (Seitz). 

Various  tumors  are  found  in  the  placenta — myxoma  fibrosum,  angiomata, 
hyperplasia  of  the  chorionic  villi,  but  es{X'cially  chorio-angiomata.  All  are  ex- 
ceetlingly  rare.  Clinically,  they  are  of  little  importance;  only  rarely  do  they  affect 
the  child  or  the  delivery.

CHAPTER  XLVII 
ANOMALIES  OF  THE  CORD  AND  OF  THE  AMNION 

ANOMALIES  OF  THE  CORD 

Knots. — Since  the  umbilical  vein  is  longer  than  the  arteries,  and  the  vessels 
longer  than  the  cord  itself,  twisting  of  the  vessels  occurs,  and  the  vein  is  twisted 
around  the  arteries.  The  veins  especially,  but  the  arteries  also,  form  loops,  and 
the  jelly  of  Wharton  is  thicker  at  such  places,  causing  nodes  on  the  cord  which  are 
called  false  knots.  These  have  no  clinical  significance.  True  knots  occur  in  the 
cord,  but  they  are  uncommon.  They  are  single  or  complicated,  and  may  even  cause 
the  death  of  the  fetus.  While  they  usually  form  during  labor  as  the  result  of  the 
child  passing  through  a  loop  and  have  no  clinical  importance,  if  they  form  early  in 
pregnancy  the  active  movements  of  the  fetus  may  draw  the  turns  so  tight  that  death 
of  the  child  results. 

Torsion  of  the  cord  is  often  found  in  aborted  fetuses,  but  one  can  seldom  assert 
that  the  torsion  caused  the  death  of  the  child.  As  many  as  380  turns  have  been 
counted  when  the  whole  cord  is  affected.  Occasionally  the  cord  is  twisted — almost 
off — right  at  the  navel,  or  at  any  one  point  of  its  length,  and  in  these  cases  stenosis 
of  the  vessels  with  fetal  death  may  follow.  In  a  given  case  it  may  be  impossible 
to  determine  whether  the  death  of  the  fetus  resulted  from  the  stricture  of  the  cord, 
or  whether  the  torsion  of  the  cord  was  produced  by  the  active  movements  of  the 
fetal  death  agony,  or  whether  the  twisting  occurred  after  the  child's  death.  Prob- 
ably all  three  occur.  In  medicolegal  cases  this  uncertainty  is  to  be  borne  in  mind. 
The  differential  diagnosis  between  torsion  of  the  cord  which  occurred  after  the  fetal 
death  from  that  occurring  before  may  be  made  certain  if  there  are  adhesions  be- 
tween the  coils  of  the  cord,  and  if,  when  the  cord  is  untwisted,  this  is  found  difficult 
and  the  shape  of  the  cord  seems  to  be  permanently  altered. 

Coiling  of  the  cord  around  parts  of  the  fetus  affects  the  child  only  when  it 
produces  an  abnormal  shortness,  or  when  the  coils  are  so  tight  that  the  circulation 
in  the  vessels  is  compromised.  It  is  said  that  such  coiling  around  the  neck  may 
cause  hydrocephalus,  atrophy,  and  cerebral  disease,  by  impeding  the  return  circula- 
tion, and  that  extremities  may  thus  be  amputated.  It  is  more  than  probable  that 
the  fetus  will  die  from  asphyxia,  the  result  of  the  compression  of  the  cord  before 
such  effects  would  be  produced.  Lesser  degrees  of  compression  make  circular 
depressions  in  the  limb  and  sometimes  peripheral  atrophy.  Fracture  of  the  ex- 
tremities may  result  during  labor  when  the  cord  entangles  them.  Twins  in  one 
amnion  usually  have  their  cords  intertwined.  Coiling  of  the  cord  around  the  neck 
is  found  in  fully  one-fifth  of  all  deliveries.  As  many  as  seven  loops  have  been  found, 
and  this  may  make  the  cord  relatively  too  short.  In  order  to  explain  the  coiling  of 
the  cord  around  the  neck  it  is  assumed  that  the  loops  lie  over  the  internal  os,  and 
in  delivery  the  child  passes  through  them.  It  is  more  probable  that,  in  its  active 
movements,  the  child  throws  the  cord  around  the  body  and  down  to  the  neck,  and 
that  the  condition  exists  for  weeks  before  delivery.  One  of  my  patients  was  terri- 
fied by  a  fire  in  an  adjoining  dwelling,  noted  excessive  fetal  movements,  and  then 
aborted.  The  left  thigh  of  the  five  months'  fetus  was  caught  in  a  tight  knot  of  the 
cord.  It  is  possible  that  the  mental  shock  caused  hemorrhages  into  the  placenta, 
and  the  dying  child  was  entangled  in  the  cord,  or  the  maternal  impressionists  might 
say  the  child  partook  of  the  mother's  fright  and  by  its  excited  motions  tied  itself

in  the  cord,  which  caused  its  death,  (oils  of  cord  around  the  neck  may  interfere 
with  the  mechanism  of  lahor,  causing  deflexion  altitudes,  delayed  rotation  of  the 
head  or  shoulders,  and  even  shoulder  presentation.  ( 'onjpressicjn  of  the  cord  Ijc- 
hind  the  pubis,  between  the  neck  and  the  bone,  may  cause  asphyxia  of  the  child, 
which  occurs  especially  in  jjrimipane,  and  is  another  reas<m  for  carefully  watching 
the  heart-tones  in  the  second  stage  of  labor. 

As  will  again  be  mentioned  in  tlie  di.scussion  of  forceps,  the  coiling  of  the 
cord  around  the  neck  and  the  presence  of  a  loop  hanging  down  ahjngside  the  head 
have  caused  very  many  fetal  deaths.  Compression  by  the  blades  of  the  instrument 
asphyxiates  the  child.

Diagnosis. — During  labor  it  is  sometimes  possible  to  feel  the  cord  in  the  nape 
of  the  neck  by  abdominal  palpation,  and  sometimi»s  the  funic  souffle  can  l>e  plainly 
and  constantly  heard  in  this  location.  During  the  forceps  ojx'ration  the  fingers 
should  be  j>assed  all  arountl  the  head  as  far  as  they  can  reach,  and  a  maneuver, 
which  is  more  successful  than  one  would  think  at  first,  is  to  pass  a  finger  l>ehind  the 
pubis  up  the  nape  of  the  neck  to  the  back.  It  is  ix)ssible  to  reach  up  ami  discover 
if  the  cord  has  come  within  the  danger  zone.     (For  the  treatment  see  Forceps.) 

M()st  authors  advise,  after  spontaneous  delivery  of  the  lu'ad,  to  feel  for  the 
cord  around  the  neck.  This  is  not  al)solutely  n«'cessary  unless  the  <'iiild  seems  to 
be  held  back  bysomething.  One  may  l>e  required  to  out  the  cord  l>efore  it  is  possible 
to  deliver  the  trunk,  and  this  is  always  advisable  when  it  seems  that  there  will  l)e 
traction  on  the  placenta — this  to  avoid  abnormalities  in  the  third  stage. 


560      THE  PATHOLOGY  OF  PREGNANCY,  LABOR,  AND  THE  PUERPERIUM 

Short  Cord. — Cases  are  recorded  where  there  was  no  cord  at  all,  the  fetus  being 
applied  to  the  placenta  through  an  umbilical  hernia.  Bayer  reported  a  cord  10.5 
cm.  and  Naegele  one  of  6.7  cm.  Clinically,  cords  are  either  absolutely  or  relatively 
short,  the  latter  being  those  where  one  or  more  turns  around  the  neck  or  extremities 
make  a  normal  cord  too  short  for  the  mechanism  of  labor. 

A  cord  must  be  long  enough  to  reach  from  the  placental  site  to  the  vulva,  and, 
if  the  placenta  is  located  in  the  fundus,  a  length  of  25  cm.  is  necessary,  not  35  cm., 
as  Kaltenbach  puts  it.  It  must  be  rememloered  that  the  uterus  follows  down  the 
child  as  it  expels  it.  Too  short  cord  may  lead  to — (a)  Delay  in  the  second  stage  of 
labor,  the  head  coming  down  with  difficulty  and  receding  quickly  as  if  it  were  drawn 
back  by  a  rubber  band;  (6)  rupture  of  the  cord  if  the  pains  are  strong,  with  death 
or  asphyxia  of  the  child;  (c)  tearing  of  the  cord  from  the  placenta;  (d)  tearing  of 
the  placenta  from  the  uterus,  causing  abruptio  placentse  or  pathologic  third  stage; 
(e)  inversion  of  the  uterus;  (/)  painful  uterine  contractions  and  secondary  inertia. 
A  diagnosis  of  too  short  cord  may  not  always  be  made.  In  one  of  my  cases  the 
patient  complained  of  a  dragging  sensation  about  the  navel  during  each  pain,  and  in 
Brickner's  case  there  was  a  desire  to  pass  urine  after  each  uterine  contraction.  In 
another  of  my  cases  a  small  amount  of  urine  was  squeezed  out  with  each  pain. 
Some  authors  have  mentioned  a  depression, — that  is,  partial  inversion  in  the  uterine 
wall, — but  most  often  the  excessive  and  quick  recession  of  the  head  after  the-pain 
has  led  to  the  diagnosis. 

Special  treatment  is  seldom  required  because  of  the  raritj'  of  the  affection.  If 
diagnosed,  one  should  watch  the  condition  of  the  child  narrowly  and  deliver  it  on 
the  first  sign  of  asphyxia.  As  soon  as  the  head  is  born  the  cord  is  to  be  cut  between 
two  clamps. 

Long  Cords. — The  longest  cord  found  in  a  service  of  over  15,000  deliveries 
was  120  cm.,  but  one  of  198  cm.  has  been  recorded.  The  average  is  60  cm. — about 
2-4  inches.  Aside  from  the  tendency  to  prolapse  and  to  coil  about  the  fetus,  they 
do  not  claim  our  interest. 

Rupture  of  the  cord  is  a  curious  accident,  for  it  may  occur  with  a  long  cord, 
and  when  we  can  find  no  reason  for  it.  Stowe,  after  reporting  a  case  of  spontaneous 
rupture  of  the  cord  which  occurred  in,  the  Chicago  Lying-in  Hospital  Dispensary 
service,  reports  the  results  of  his  tests  to  discover  the  tensile  strength  of  the  cords. 
They  carried  weights  varying  from  8  to  22  pounds.  In  a  case  of  mine  the  child  was 
delivered,  deeply  asphyxiated,  with  the  cord  broken  eight  inches  from  the  navel. 
The  broken  ends  were  not  jagged,  but  cut  as  if  with  dull  scissors,  and  the  thickness 
at  the  point  of  rupture  was  8  mm.  In  another  case  the  brittle  cord  was  caught  be- 
tween the  blade  of  the  forceps  and  the  head,  and  sharply  severed,  as  with  a  knife. 

Neoplasms  occur  exceedingly  rarely  in  the  cord.  Myxoma,  sarcoma,  and  der- 
moid have  been  reported.  Rupture  of  a  varix  of  the  cord,  with  hematoma,  espe- 
cially near  the  belly  of  the  child,  is  occasionally  observed.  Immense  increase  of  the 
jelly  of  Wharton  may  change  the  cord  to  a  heavy,  thick,  glassy  rope — in  one  of  my 
cases  it  was  thicker  than  a  large  thumb.  Cysts,  relics  of  the  ductus  omphalo- 
mesentericus  or  of  the  allantois,  may  rarely  be  found,  and  sometimes  a  cyst  seems 
to  result  from  liquefaction  of  the  Wharton  jelly. 

Syphilis  of  the  cord  has  already  been  mentioned.  The  thickening  of  the  tunica 
media  of  the  vessels  and  calcification,  with  obliteration  of  the  lumen,  found  here, 
have  also  been  found  in  other  conditions,  and,  therefore,  they  are  not  pathog- 
nomonic of  lues. 

Abnormal  Insertion  of  the  Cord.— Ordinarily,  the  cord  is  inserted  at  or  near 
the  center  of  the  placenta.  Eccentric  insertion,  even  attachment  at  the  margin,  is 
not  rare.  Battledore  placenta  has  no  clinical  importance.  When  the  cord  is  at- 
tached to  the  membranes  and  the  vessels  course  a  greater  or  less  distance  between 
the  amnion  and  the  chorion  to  the  body  of  the  placenta  we  speak  of  velamentous 


ANOMALIES  OF  THE  COKD  AND  OF  THE  AMNION

insertion — insert io  vchiincntosa  (Fig.  493).  KnihryoloRists  arc  still  at  variance 
as  to  mechanism  of  the  production  of  the  aberrant  insertion  of  the  cord.  Von 
Franque's  idea  that  the  exceptionally  good  nutritional  conditions  of  the  reflexa 
lead  to  the  insertion  of  the  abdominal  pedicle  here  seems  (juite  pluu.sible,  but  is 
unproved  (Peiser). 

Velamentous  insertion  is  often  found  with  other  an(jmiilies*(jf  tin-  j)lucenta,  as 
infarcts,  placenta  succenturiata,  bilobata,  and  previa.  It  is  common  with  twins 
and  the  rule  with  triplets.  To  the  child  this  abnormal  inserticm  of  the  cord  is 
dangerous  only  when  the  vessels  run  across  the  lower  uterine  segment;  then  its 
life  may  i)e  lost  througii  hemorriuige,  from  tearing  of  one  or  more  of  tin-  vess<'ls  when 
the  membranes  rupture,  or  asi)hyxia  from  ct^mpre.ssion  of  the  vessels  and  the  cord 
during  the  passage  of  the  head.  Both  twins  may  lileed  to  death  from  the  tearing  of 
one  vessel.     Occasionally  a  diagnosis  may  be  made  before  rupture  of  tlic  inem-

branes — the  pulsating  ves.<;els  may  be  felt  inside  the  cervix  coursing  over  the  jx)uting 
bag  of  waters.  These  vessels  are  not  in  the  forelying  cord,  because  light  pressure 
upward  would  displace  the  latter.  A  slight  but  continuous  hemorrhage  after  the 
rupture  of  the  membranes,  with  weakening  and  rapidity  of  the  fetal  heart-tones,  is 
diagnostic.  Placenta  pr;evia  and  other  maternal  causes  of  bleeding  are  easily  elimi- 
nated and  by  exclusion  the  trui'  conilition  recogni/etl. 

Treatment. — If  the  diagnosis  is  made  befoR>  rupture  of  the  membranes,  the 
latter  must  ho  delayed  until  dilatation  of  tlie  cervix  is  complete,  which  is  accom- 
plished by  i)lacing  a  soft  elastic  colp«'urynter  in  the  vagina  and  putting  the  woman  in 
the  elevated  Sims  i)osition.  \\'hen  the  os  is  fully  oi)enc(l.  the  membranes  are  to  l>e 
punctured  l)etween  the  ves.sels  and  delivery  elTected  as  rapidly  lus  is  consistent  with 
the  safety  of  the  mother. 

Hernias  into  the  conl  are  not  so  very  rare.  This  nmst  always  be  thought  of 
36

while  tying  the  cord.  Hernias,  if  operable,  should  be  closed  immediately,  to  avoid 
peritonitis.  Occasionally  the  skin  of  the  belly  runs  up  for  a  varying  distance  on 
the  cord,  called  "skin  navel,"  and  after  the  stump  has  fallen  off  the  retraction  of 
the  center  inverts  this  skin,  making  a  deep  retracted  navel.  Sarcomphalus  is 
likelv  to  result  in  such  instances. 


ANOMALIES  OF  THE  AMNION 

Beside  certain  minor  pathologic  findings  on  the  amnion,  as  caruncles,  epithe- 
lioid deposits  containing  lanugo  hairs,  cysts  near  the  insertion  of  the  cord,  scratch- 
marks  from  the  child's  nails,  and  adhesions  to  the  fetus,  the  amnion  presents  two 
important  conditions  for  study — polyhydramnion  and  oligohydramnion,  the  first 
meaning  an  excessive  quantity  and  the  latter  an  abnormally  small  amount  of  liquor 
amnii.  Normally,  the  amount  varies  within  wide  limits,  from  600  to  2000  gm. 
We  do  not  know  the  exact  source  of  the  liquor  amnii,  and,  therefore,  it  is  impossible 
to  give  a  scientific  etiology  of  the  anomalies  of  the  fluid. 

Polyhydramnion,  hydramnion,  or  hydramnios,  is  more  common  than  oligo- 
hydramnion, and  occurs  about  once  in  200  cases.  As  many  as  15  and  30  liters  of 
fluid  have  been  reported,  but  such  cases  are  exceedingly  rare.  In  one  of  my  cases 
we  measured  8  quarts,  and  much  more  escaped  into  the  bed  and  onto  the  floor. 
Ovular  and  maternal  causes  have  been  invoked.  Of  ovular,  the  fetus,  the  cord,  the 
amnion,  and  the  placenta  may  be  involved.  (1)  IMalformations  of  the  child,  es- 
pecially those  showing  absence  of  closure  of  fetal  cavities,  harelip,  anencephalus, 
ectopia  vesicae,  spina  bifida,  etc.  Internal  deformities  are  sometimes  associated 
with  the  polyhydramnion,  for  example,  occlusion  of  the  esophagus,  stenosis  of  the 
pylorus.  In  the  former  instance  the  liquid  is  supposed  to  be  due  to  transudation 
from  the  insufficiently  covered  l^lood-vessels  of  the  deformed  part.  (2)  Diseases  of 
the  child  involving  obstruction  of  its  venous  circulation,  and  causing  stasis,  edema, 
and  exudation,  for  example,  stenosis  of  the  cord,  stenosis  of  the  aorta,  of  the  ductus 
Botalli,  heart  disease,  cirrhosis  of  the  liver,  white  pneumonia  (syphilis),  placental 
disease,  obliteration  of  the  placental  blood-vessels,  chorio-angioma.  In  these  cases 
the  fetal  kidneys  increase  their  action,  and  there  is  perhaps  more  urine  in  the  liquor 
amnii.  (3)  Hydramnion  in  unioval  twins  is  not  uncommon,  and  one  or  both  of  the 
ova  may  be  affected  equally,  or  one  more  than  the  other,  or  there  may  even  be  oligo- 
hydramnion in  one  ovum.  In  homologous  twins,  when  one  child  is  stronger  than 
the  other,  its  heart  forces  blood  through  the  intermediate  or  "third"  circulation 
into  the  vascular  system  of  the  other,  causing  enlargement  of  the  latter's  heart, 
increased  kidney  action,  and  even  transudates  from  its  vessels.  (4)  Increase  of  the 
fetal  urine  may  cause  hydramnion,  but  we  know  no  cause  for  the  former.  Jaggard 
reported  a  fetus  with  deficient  kidneys  and  oligohydramnion  (Wilson). 

Older  writers  spoke  of  an  amnionitis,  and  later  investigators  have  found  in- 
flammatory and  degenerative  changes  in  the  amnial  epithelium.  Ahlfeld  believes 
that  an  early  amnionitis  produces  adhesions  to  the  fetus,  with  resulting  deformities, 
such  as  craniorachischisis,  gastroschisis,  amputation  of  the  extremities,  etc.  The 
anmion  offers  promise  of  great  results  from  scientific  investigation. 

Maternal  diseases  are  seldom  the  cause  of  polyhydramnion:  (1)  All  those 
affections  which  make  general  anasarca — cardiac,  lung,  liver,  and  kidney;  (2) 
syphilis,  leukemia,  chronic  anemia — in  such  cases  the  fetus  usually  has  hydrops 
universalis. 

Clinical  Course. — Two  varieties  are  distinguishal^le — the  acute — very  rare — and 
the  chronic,  the  commoner.  Acute  hydramnion  is  graver,  and  usually  leads  to 
abortion.  It  begins  during  the  fourth  or  fifth  month,  and  rapidly  expands  the 
uterus  to  colossal  size,  pressure  symptoms  being  early  and  pronounced.  There  are 
pain  in  the  abdomen,  back,  and  thighs,  feeling  of  great  distention,  dyspnea,  espe-

thighs,  and  even  the  ahdomcn,  witii  cncjrmous  distention  of  the  lattiT,  will  he  found. 
The  uterus  may  be  larger  than  at  term,  the  belly  so  tight  and  tender  tliat  palpation 
is  rendered  negative,  but  fluctuation  is  usually  obtainable.  Stria*  gravidarum 
cover  the  skin,  and  often  minute  hemorrhages  bestrew  it;  fetal  i)artsare  nitt  palpable, 
and  the  heart -tones  may  be  inaudible.  N'aginally,  the  (M-rvix  is  found  high  up, 
effaced,  ami  the  os  usually  opened.  As  a  rule,  acute  hydranmion  terminates  in 
abortion  before  the  sixth  month,  or  the  sj^mptoms  become  so  threatening  that  the 
attendant  must  interfere.  Twins  are  often  found  in  sucli  ca.ses,  and  a  spcjntaneous 
cure  may  follow  if  one  of  them  should  die. 

J)i(t(jn()sis. — If  a  diagnosis  of  pregnancy  had  aln-ady  been  made,  the  rapid  en- 
largement of  the  uterus  with  abdominal  .symptoms  will  be  easily  explained.  Hyda- 
tidiform  mole  causes  not  such  rapid  gro^^'th  of  the  uterine  tumor,  and,  further,  it  is 
almost  always  complicated  by  hemorrhages.  (lencTally,  the  first  duty  is  to  diag- 
nose ])regnancv,  which  is  usually  not  dilhcult  if  all  the  aids  are  called  upon,  ('(jii- 
tractions  occurring  in  the  abdominal  tumor  on  one  occa.^ion  enabled  me  to  diagno.se 
the  condition  when  all  other  fimlings  were  cciuivocal.  Ovarian  cyst  oftenest  nupiires 
differentiation,  but  in  this  condition  the  uterus  is  usually  found  below  the  large 
fluctuating  tumor,  the  cervix  is  closed  and  hard  (open  and  soft,  with  palpable  mem- 
branes in  hytlramnion),  and  the  symptoms  and  other  signs  of  pregnancy  are  absent. 
Ascites  shows  the  characteristic  area  of  tympany  arounil  the  navel,  which  changes 
with  position.  Encysted  (tubercular)  ascites  was  once  mistaken  for  polyhydram- 
nion.  In  critical  cases,  where  a  diagnosis  must  be  made,  it  is  ju.stifiable  to  use  the 
uterine  sound  because,  if  the  case  really  is  acute  hydranmion,  the  puncture  of  the 
meml)ranes  is  the  proper  treatment. 

Treatment  of  acute  hydranmion  is  abortion,  by  letting  off  the  waters,  which 
must  be  done  slowly  to  avoid  .shock,  the  case  being  then  left  to  nature,  and  other 
interference  being  made  only  on  special  indication. 

Chronic  Ilydnimnion. — This  dilTers  from  the  acute  in  that  the  course  is  much 
less  stormy — it  does  not  lead  so  often  to  abortion,  though  premature  labor  is  fre- 
quent. It  is  commoner  and  a  little  more  amenable  to  treatment.  It  may  occur  in 
ectopic  gestation,  which  renders  diagnosis  very  difficult.  C'au.sation  and  symptoms 
are  the  same  as  in  the  acute  form,  but  the  latter  are  less  marked  ami  of  longer  dura- 
tion. Enormous  distention  of  the  uterus  may  occur,  with  resulting  cardiac  distress 
and  kidney  insufficiency.  The  patient  may  l)e  annoyed  In'  false  labor  i)ains  for 
weeks  before  deliver^'.  The  diagnosis  lies  most  often  between  hydranmion  and 
twins,  but  it  must  l)e  remembered  that  they  are  often  a.s.sociated.  In  one  of  my 
ca.ses  the  bag  of  waters,  felt  over  the  internal  os,  was  relaxed,  while  the  uterus,  felt 
abdominally,  was  very  ten.se,  a  fact  which  Remy  and  .\hlfeld  noted,  and  whi<-h 
they  u.sed  for  the  tliagnosis  of  hydramnion  of  the  upjxT  twin.  Fluctuation  is 
demonstrable  only  in  the  hydramniotic  sac;  it  does  not  pass  through  the  septum 
between  the  twins. 

The  prognDsis  of  acute  hydranmion  is  good  for  the  mother,  U^'ause  abortion 
usually  terminates  the  case  early.  In  general  the  prognosis  is  not  bad,  but  one 
should  remember  the  dangers — kidney  lesions,  canliac  collapse,  resi)iratory  failure, 
hydroperitoneum,  and  hytlropleura.  Labor  may  bring  added  trt)ublt^ — for  ex- 
ample, a  tedious  first  stage,  sometimes  lasting  days,  prolap.se  of  the  cord  when  the 
nninbranes  rupture  and  the  sudden  rush  of  the  waters  takes  place;  abnonnal 
presentations  and  j)ositit)ns  of  the  child,  weak  labor  |)ains,  the  last  thre*'  reipiiring 
operative  interference;  att)nia  uteri  and  postpartum  hemorrhage,  which  t)ften  is 
hard  to  stop.  The  sudden  rush  of  the  waters,  besides  causing  the  mentiom'd  anoma- 
lies, may  leave  so  small  a  uterine  cavity  that  abruptio  placenta"  results,  or  the  heart 


564      THE  PATHOLOGY  OF  PREGNANCY,  LABOR,  AND  THE  PUERPERIUM 

cannot  stand  the  shock  of  the  sudden  cUminution  of  intra-a])donunal  tension.  Fi- 
nally, the  cause  of  the  polyhydramnion  may  have  a  bearing  on  the  prognosis,  for 
example,  syphilis,  anemia,  heart  and  kidney  lesions. 

For  the  child,  the  prognosis  is  bad  in  acute  hydramnion,  but  in  the  chronic 
forms  it  is  fairly  good.  An  expression  of  opinion  should  be  guarded,  because  of  the 
frequency  of  prematurity  and  of  fetal  deformities,  which  may  make  extra-uterine 
existence  impossible.  In  the  higher  degrees,  the  mother  being  very  cyanotic,  the 
child  or  children  may  die  of  asphj^xia  before  delivery,  and  many  succumb  during 
operative  procedures  necessitated  by  prolapse  of  the  cord,  etc. 

Treatment. — Sj^ihilis,  anemia,  renal  and  cardiac  disease,  of  course,  are  to  be 
appropriate!}^  treated,  though  much  success  is  not  attained.  When  the  symptoms 
become  marked,  the  patient  should  stay  in  bed,  on  an  antinephritic  diet,  and  should 
be  carefully  watched.  Should  the  heart  begin  to  suffer  or  the  kidneys  prove  de- 
fault, labor  is  to  be  induced,  the  best  method  being  to  let  off  the  excessive  waters 
through  a  small  trocar,  such  as  is  used  for  ovarian  cysts.  It  is  important  to  let  the 
waters  off  slowly  to  avoid  shock  from  sudden  decrease  of  intra-abdominal  tension, 
and  to  prevent  the  prolapse  of  the  cord  or  extremities.  Deliverj'  of  the  child  should 
also  be  slow,  to  enable  the  uterus  to  get  a  better  hold  on  itself  by  retraction  of  its 
fibers.  Preparations  for  postpartum  hemorrhage  are  to  be  made  l^eforehand,  and 
the  placenta  removed  on  the  first  indication,  after  which  the  uterovaginal  tract  is 
to  be  firmly  packed  "wdth  gauze. 

Oligohydramnion. — Decrease  of  the  amount  of  liquor  amnii  is  rare,  and  in  such 
cases  there  may  be  a  few  spoonfuls  of  thick,  viscid  or  cloudy,  yellowish-green  fluid, 
insufficient  to  fill  the  interstices  between  the  fetal  parts  and  the  uterus.  If  the  con- 
dition occurs  early  in  fetation,  it  results  in  more  or  less  adhesion  of  the  amnion  to 
the  fetus,  causing  deformities,  for  example,  hemicephalus,  cranioschisis,  gastro- 
schisis,  spina  bifida,  amputation  of  extremities,  curvatures,  ankylosis  of  joints,  and 
skin  defects.  If  the  lic}uor  amnii  is  lacking  in  the  later  months,  the  skin  of  the  child 
becomes  dry  and  leathery,  the  fetal  body  is  cramped  together,  club-foot,  drop-wrist, 
skin  defects  on  the  shoulders,  trochanters,  malleoli  (decubitus),  curvature  of  the 
spine,  shortening  of  the  nmscles,  such  as  wry-neck,  talipes  calcaneus,  etc.,  are  found 
— all  the  result  of  limitation  of  the  confines  of  the  child  and  of  pressure  of  the  uterine 
wall  on  its  body. 

These  same  conditions  are  found  in  extra-anmiotic  development  of  the  child  and 
in  extra-uterine  pregnancy. 

Nothing  is  definitely  known  of  the  causation  of  oligohydramnion.  Jaggard's 
case  of  absence  of  urethra  and  kidney  has  been  referred  to.  Oligohydramnion  can 
affect  one  twin,  there  being  an  excess  of  fluid  with  the  other. 

During  labor,  which  is  often  premature,  painful  uterine  contractions,  weak 
pains,  protracted  first  stage,  a  tendency  to  abruptio  placentte,  and  increase  in  the 
dangers  to  the  child  have  been  noted.

SECTION  VI 
THE  PATHOLOGY  OF  LABOR 


An  obstetric  case  is  a  surgical  case,  with  more  tiian  the  usual  surgical  aspects. 
DldiT  writers  used  to  speak  of  eutocia  and  dystocia,  the  former  meaning  normal,  the 
latter  abnormal,  lal)or.  No  two  authorities  are  agreed  as  to  where  eutocia  ends 
and  dystocia  ijegins.  Most  authors  believe  that  lal)or  in  the  human  female  borders 
very  closely  on  the  ])atii()l<)gic,  but  I  am  convinced  that,  today,  measured  by  our 
present  standards,  lal)()r  cannot  i)e  called  a  normal  function.  To  mention  only  one 
reason  for  so  considering  it,  the  almost  invariable  injury  to  the  pelvic  floor  may  be 
cited.  No  other  function  of  the  body,  normally  executed,  is  attended  by  perma- 
nent damage  to  structure.  Should  such  damage  occur,  we  call  the  process  patho- 
genic and  patiiologic.  I  believe  that  the  notion  that  lal)()r  is  ncjrmal  is  a  fallacy, 
and  tiiat  tliis  fallacy  is  fundamentally  responsil)le  for  the  still  high  mortality  and 
morbidity  which  attend  the  parturient  function.  Taking  for  granted  that  parturi- 
tion is  normal,  the  State  allows  ignorant  midwives  and  half-instructed  medical 
students  to  assume  the  heavy  resix)nsibilities  of  its  conduct.  Since  the  public  is 
taught  to  believe  that  labor  is  jihysiolofyc,  it  refu.ses  to  recognize  the  dignity  of  the 
science  and  the  high  degree  of  art,  of  oijstetrics,  and,  as  a  result,  the  field  of  its  prac- 
tice is  not  made  inviting  to  the  best  men  of  the  profession.  Such  a  state  of  affairs 
naturally  explains  why  20,000  women  die  every  year  in  our  country  from  the  eflfects 
of  ciiildbirth,  why  nearly  every  mother  carries  the  marks  of  injury  inflicted  iluring 
labor,  and  why  a  hundred  thousand  infants  are  annually  lost  during  delivery. 

It  is  best  to  regarel  every  labor  case  as  a  severe  operation.  Like  the  surgeon, 
the  obstetrician  should  consider  the  strength  of  the  patient  in  standing  the  shock, 
the  asepsis  and  antisepsis,  the  nature  and  technic  of  the  operation,  and,  finally,  all 
the  complications  which  are  likely  to  arise. 

So,  tluring  lal)or,  it  is  necessary  and  our  duty  to  have  a  clear  knowledge  of  the 
patient's  condition,  especially  of  the  heart,  lungs,  kidneys,  and  blood;  second,  we 
nmst  know  accurately  what  is  going  on  during  the  labor,  that  is,  we  must  be  thor- 
oughly accjuainted  with  the  mechanism  of  tiie  j)articular  labor,  the  strength  of  the 
powers,  tiie  greatness  of  the  resistances,  and  the  relation  betwe«'n  them;  thiril.  we 
must  be  aware  of  all  possible  complications  and  the  i)articular  ones  likely  to  arise 
in  this  jxirticular  case,  and  know  how  to  prevent  and  treat  them;  and,  finally,  we 
must  know  and  practise  the  strict  princijiles  of  asepsis  and  antisepsis,  that  the 
latest  .standards  demand.  To  meet  all  these  obligations  is  the  duty  of  the  obstetri- 
cian, and  a  conscientious  man  will  find  little  time  for  idling  at  a  lai>or  cas<'.  It  re- 
quires studious  regard  of  the  patient  during  her  pregnancy,  and  getting  her  into  the 
best  possible  condition  for  the  ordeal  of  i)arturition.  It  recjuires  a  prompt  response 
to  the  call  to  the  labor,  a  careful  and  painstaking  examination  on  arrival,  and  a 
proper  valuation  of  all  the  conditions  found.  It  recpiires  attentive  conduct  of  the 
case  from  the  beginning  to  the  end,  and  a  preparedness  for  doing  the  usual  work  of 
a  delivery,  plus  far-reaching  provision  and  al)ility  for  all  emergencies. 

In  general,  the  al>normalities  of  a  lalH)r  may  l)e  classed  under  three  heaiis: 
(1)  Anomalies  of  the  powers;  (2)  disproportion  U^twei^n  the  passage  and  the  pass- 
engers;   (3)  complications  on  the  part  either  of  the  mother  or  of  the  fetus.

566  THE    PATHOLOGY    OF    LABOR 

WTien,  in  the  course  of  his  study  of  a  labor  case,  the  accoucheur  notes  that  one 
or  the  other  of  the  three  irregularities  is  present  or  threatens,  he  decides  that  he 
must  do  something  to  save  the  mother  or  the  child  from  disaster — in  other  words, 
he  finds  an  indication  for  interference.  An  "indication,"  therefore,  is  a  reason  for 
interference  in  the  course  of  a  given  case.  However,  certain  circumstances,  char- 
acters, or  phases  of  the  case  may  cause  us  to  modify  the  indication;  in  other  words, 
the  accoucheur  must  consult  the  conditions  of  the  case  in  determining  the  course  of 
procedure.  A  "  condition,"  therefore,  is  a  prerequisite  or  requirement  which  governs 
the  indication.  For  example,  in  eclampsia  the  indication  is  for  immediate  d(4ivery. 
The  state  of  the  cervix  is  one  of  the  conditions  which  will  determine  what  mode  of 
dehverj'  will  be  selected.  The  study  of  the  case,  and  the  determination  that  this  or 
that  remedy  or  course  of  procedure  is  required,  we  call  "placing  the  indication." 
After  this  the  conditions  are  consulted.  If  they  are  all  fully  met,  the  line  of  procedure 
is  carried  out ;  if  not,  the  indication  is  to  be  revised  until  it  does  meet  and  satisfy 
all  the  conditions,  or,  if  the  indication  is  imperative,  the  conditions  are  forced  to 
meet  it.  It  is  here  that  the  judgment  of  the  accoucheur  comes  to  the  test,  and, 
speaking  generally  and  reflectively,  I  affirm  that  there  are  no  situations  in  all  medi- 
cine and  surgery  that  require  broader  knowledge,  finer  discernment,  more  logical 
reasoning,  and  more  courageous  purpose  for  their  control  than  do  the  problems  of 
obstetrics.

ANOMALIES  OF  THE  POWERS 

In  the  first  stage  of  luljor  tlu;  uterus  docs  all  the  work.  Regularly,  with  in- 
creasing fre(iuency  and  strengtli,  its  muscle  contracts,  slowly  reaching  an  acme 
and  then  relaxing.  In  this  way  the  lower  uterine  segment  is  developed,  the  hydro- 
static i)ag  of  waters  formed,  the  cervix  efTaced,  and  the  os  dilated.  In  the  second 
stage  the  larger  part  of  the  work  is  done  by  the  al)dominal  muscles.  The  uterus  by 
this  time  is  well  drawn  up  over  the  child  and  can  exert  i)ut  little  power.  While  in 
some  instances  the  uterus  expels  the  child  unaided,  its  main  action  in  this  stage  is 
forcing  the  presenting  part  against  the  pelvic  fioor,  which,  reflexly,  elicits  the  action 
of  the  abdominal  muscles — the  bearing-down  efforts.  In  discu.ssing  this  subject, 
therefore,  we  will  considcT,  first,  antjmalies  <jf  the  uterine  and  second  tho.se  of  the 
abdominal  action. 

Anomalies  of  the  Uterine  Action. — The  pains  may  be  too  weak  or  too  strong, 
too  seldom  or  too  frecjuent,  too  short  or  too  long,  and  they  may  be  irregular  in  time 
and  in  character,  too  j^ainful,  (jr,  rarely,  painh'ss.  Even  normally,  much  variation 
may  be  noted  as  regards  the  time,  rhythm,  and  strength  of  the  labor  pains  in  difTer- 
ent  women.  Knowledge  of  the  character  of  the  pains  in  preceding  labors  will 
enable  us  to  predict  the  kind  of  uterine  action  in  sul>sequent  deliveries,  since  they 
are  usually  much  alike,  i>ut  exceptions  are  not  rare. 

False  pains  are  tiie  contractions  of  pregnancy,  which,  toward  the  end  of  gesta- 
tion, become  perceptil)le,  even  painful,  to  the  gravida.  They  are  esj>ecially  marked 
at  the  time  of  lightening,  and  may  force  the  head  do^^Tl  into  the  pelvis.  According 
to  Schatz,  they  recur  with  a  certain  perioflicity,  the  intervals  being  less  by  one-half 
as  term  approaches.  All  the  usual  symptoms  of  an  actual  lal)or  pain  may  be  pres- 
ent, that  is,  pain,  hanh'uing  of  the  uterus,  regularity,  even  dilatation  of  the  cervix 
and  rupture  of  the  membranes.  Most  authors  regard  the  last  two  as  indicative  of 
the  beginning  of  actual  labor.  Indeed,  it  is  often  impo.ssible  to  say  when  pregnancy 
ends  and  labor  starts,  i)ut  th(\se  points  may  help  in  the  diagnosis:  false,  or  preg- 
nancy, pains  are  of  even  intensity,  while  true  pains  grow  stronger  apace;  they 
cease  after  a  day  or  so;  they  are  out  of  the  time  of  the  exix'cted  labor,  and  if  their 
type,  i.  e.,  whether  they  apj^ear  at  intervals  of  three,  four,  or  six  weeks,  is  known, 
they  will  recur  on  the  days  which  wouUl  correspond  to  the  end  of  one-half  of  the 
previous  interval;  while  the  cervix  may  oiwn,  it  is  not  shortened  nor  effaced,  the 
membrant's  rarely  rupture,  and  the  bloody  show  (Um's  not  appear.  Fals<'  pains  are 
not  strengthened  by  pituitrin  (Hofl>auer).  It  is  important  to  recognize  tlie  false 
pains  and  treat  them  jus  such,  l>ecause  if  the  woman  were  considered  to  be  in  lalK)r, 
when  actually  she  is  not,  much  unneces.sary  and  harmful  examination  and  inter- 
ference might  be  instituted.  Treatment  consists  of  rest  in  IkmI.  narcotics,  and  ex- 
pectancy. The  author  docs  not  agree  with  those  who  wouhl  allow  such  a  c:ise  to 
continue  far  beyond  the  n()rmal  t«'rm  of  jiregnancy.  See  Prolongetl  Pregnancy 
and  Induction  of  Labor  at  Term.) 

Weak  Pains. — Inertia  uteri,  atonia  uteri,  or  uterine  atony  may  show  itself  in, 
first.  infre(|uent  contractions,  weak  contractions,  and  t(K)  short  contractions;  usually 
the  three  are  combined.  Clinically,  we  must  descrilM>  the  condition  as  it  affects 
the  first  stage,  or  the  dilatation  of  tlu'  cer\"ix;  the  second  stage,  the  expulsion  of  the 
fetus;   and  the  third  stage,  or  the  jXTiod  of  the  after-birth.     In  tlie  first  stage  labor 

507 


568  THE    PATHOLOGY    OF   LABOR 

is  unduly  prolonged,  the  pains  are  weak,  at  long,  irregular  intervals,  and  last  only  a 
few  seconds.  Sometimes  they  intermit  for  a  few  hours  or  days,  reminding  one  of 
the  false  pains  just  considered.  After  a  rest,  uterine  action  is  resumed,  but  usually 
with  more  force.  Dilatation  of  the  cervix  may  require  several  days,  and  the  patient 
is  exposed  to  the  dangers  of  sepsis  and  exhaustion.  Should  fever  arise,  which  is 
especially  likely  if  the  bag  of  waters  is  ruptured,  the  pains  start  up  with  vigor  and 
terminate  the  labor,  if  this  is  possible.  Ordinarily,  the  child  is  in  no  danger  at  this 
time.  As  long  as  the  bag  of  waters  is  intact,  serious  trouble  is  unlikely.  Should 
it  rupture  early,  the  uterus  may  retract  firmly  on  the  fetus,  and  for  the  mother  there 
is  then  danger  of  infection  of  the  cavity  of  the  uterus.  Either  the  germs  wander  up- 
ward or  are  carried  up  by  the  too  frequent  examinations.  In  two  cases  of  the 
author  the  children  came  to  the  world  already  infected,  one  with  gonorrheal  oph- 
thalmia and  one  with  gastro-intestinal  sepsis. 

During  the  second  stage  weak  uterine  pains  are  responsible  for  weak  abdominal 
action,  because  the  presenting  part  is  not  forced  against  the  perineum  strongly 
enough  to  arouse  the  abdominal  muscles.  Expulsion  is  slow  or  stopped,  causing 
danger  to  the  mother  from  pressure  necrosis  of  the  pelvic  viscera,  which  may 
eventuate  in  fistulas.  The  child  in  utero  is  endangered  by  asphyxia.  In  the  third 
stage  weak,  infrequent,  or  short  pains  are  grave,  because  of  imperfect  separation  of 
the  placenta,  retention  of  membranes,  and  hemorrhage  from  insufficient  closure  of 
the  vessels  at  the  placental  site. 

Etiology. — Primarily  weak  pains  may  be  due  to  poor  general  health,  chronic 
wasting  disease,  tuberculosis,  or  anemia,  though  in  acute  affections  the  uterus 
generally  acts  well.  The  nervous  mechanism  may  be  disturbed,  the  muscle  being 
poorly  innervated,  or  the  nervous  balance  being  imperfect.  A  shock  may  frighten 
the  pains  away,  or  fear  of  an  operation  hasten  them.  In  hyperesthetic  women  the 
suffering  they  cause  may  be  inhibitory,  and,  contrary  to  what  would  be  expected, 
morphin  will  sometimes  strengthen  weak  pains.  Local  causes  are:  infantile  uterus, 
fibroids,  and  other  tumors  in  or  near  the  uterus;  peritoneal  adhesions,  w^hich  inter- 
fere with  the  muscle  action;  full  rectum  and  bladder,  which  act  like  the  last;  ab- 
normal position  of  the  uterus;  retroflexion  or  anteversion  (pendulous  abdomen); 
disease  of  the  uterine  wall;  scars  from  previous  operations;  chronic  metritis,  with 
increase  of  fibrous  and  decrease  of  muscular  tissue;  endometritis;  too  frequent 
child-bearing,  with  overstretching;  old  primiparity;  conditions  of  the  ovum  which 
overdistend  the  uterus,  for  example,  polyhydramnion,  twins;  physometra;  ab- 
normal positions  of  the  child — breech,  shoulder,  face,  occipitoposterior,  which  pre- 
vent it  from  pressing  on  the  great  cervical  ganglion;  generally  contracted  pelvis; 
adhesion  of  the  membranes  around  the  os,  which  act  in  the  same  way,  a  poorly 
shaped  bag  of  waters  being  formed.  Secondary  weak  pains  are  due  to  fatigue  from 
overwork  and  to  retraction  of  the  contractile  portion  of  the  uterus  al)ove  the  child. 
Sometimes  they  are  due  to  stricture  of  the  uterus  (vide  infra). 

The  diagnosis  of  atony  of  the  uterus  is  easy — the  organ  does  not  harden  firmly 
with  the  pain,  and  the  contraction,  timed  with  a  watch  and  feeling  the  fundus  with 
the  hand,  lasts  only  a  few  seconds.  There  is  no  progress  in  labor,  very  little  suffer- 
ing, and  the  pains  have  no  effect  on  the  fetal  heart-tones.  An  important  part  of 
the  diagnosis  is  the  determination  of  the  point  when  the  mother  and  child  begin  to 
be  endangered.  For  the  child,  this  is  usually  late  in  the  second  stage,  is  due  to 
asphyxia  from  the  reduction  in  size  of  the  placental  area,  and  is  discovered  by  aus- 
cultation. For  the  mother,  it  depends  largely  on  the  cause,  the  worst  cases  being 
those  of  weak  pains  in  the  presence  of  disproportion  between  the  head  and  the  pelvis. 
Here  the  parts  beneath  the  zone  of  compression  become  edematous,  sometimes 
bloody,  later  anemic,  necroses  begin,  and  in  all  cases  the  tissues  lose  their  bacteri- 
cidal power,  which  invites  infection.  Swelling,  transudation,  edema,  fetid  dis- 
charge, pain,  nausea  and  vomiting,  fever,  etc.,  indicate  tin!  time  for  interference.

Prognosis. — This  depends  on  the  cause.  The  greatest  dangers  are  sepsis  from 
too  long  waiting,  from  too  many  internal  examinations  and  manipulations,  and  the 
injuries  inflicted  by  too  early  and  unnecessary  oix-rating. 

Trcnttnenl  shf)uld  he  varied  with  the  cause,  and  is  medical  or  mechanical.  One 
of  the  best  remedies  is  to  put  tiie  patient  t(j  sleep,  and  m<jri)hin,  '  (•  grain  hypod<'r- 
mically,  or  20  grains  sodium  bromid,  may  be  used.  Morphin  is  safe  for  the  child 
only  early  in  the  first  stage  of  labor.  The  effect  is  better  if  the  parturient  is  given 
a  full  warm  bath  beforehand.  While  in  the  tub,  the  genitals  are  protected  against 
the  access  of  the  infected  bath-water  by  means  (^f  a  large  pad  of  c(jtton.  After  a 
good  sleep  the  patient  usually  has  regular,  vigorous  pains.  Krg<jt  is  never  used,  ;ind 
quinin  seldom.  Though  some  practitioners  report  success  with  the  latter  drug,  my 
own  experience  has  been  negative,  and  several  times  it  seemed  to  cause  the  pre- 
nuiture  discharge  of  meconium  and  annoying  post|)artum  (jozing.  Sugar  in  half- 
ounce  doses  has  (K-casionally  seemed  t(j  help.  Latterly,  jjituitrin,  introduced  by 
Ilofbauer,  L')  minims  hypodermically  every  three  hours  for  three  do.ses,  has  been 
usetl  with  success  in  pure  atonia  uteri.  In  my  exjx'rience  it  does  .strengthen  the 
pains,  i)ut  there  is  a  slight  danger  of  a.sphyxia  of  the  child  and  postpartum  hemor- 
rhage. On  this  account  I  start  with  5  minims  and  give  a  larger  dose  only  if  re- 
(juired.  If  a  stimulant  is  desjretl,  strychnin,  ^\y  grain  every  three  hours,  and  hot 
coffee  may  be  used.  Much  i)atience  is  to  be  exercised,  and  suggestion,  with  mental 
and  moral  support,  nmst  Ijc  given  the  parturient.  In  many  instances  a  large  dose  of 
castor  oil  will  prove  effectual. 

Mechanical  measures  are:  hot  sitz-l)ath;  hot-water  bag  to  the  fundus;  uterine 
mas.sage;  letting  the  i)atient  change  her  i)osition  or  walk  al)out;  electricity  to  the 
uterus  (useless  in  my  experience);  the  electric  vibrator  applied  evenly  over  the 
fundus;  a  hot  soapsuds  enema  (very  effective);  hot  vaginal  douches  (115°  F.), 
repeated  every  three  hours  (not  reconunended) ;  insertion  of  a  bougie  into  the  lower 
uterine  segment;  application  of  a  small  colpeurynter  above  the  cervix,  and  traction 
on  it  so  as  to  irritate  the  cervical  ganglion;  packing  the  cervix  or  vagina  or  both 
with  gauze;  separation  of  the  membranes  around  the  internal  os  ami  lower  uterine 
segment,  to  form  an  effective  hydrostatic  bag  of  waters;  and  puncture  of  the  mem- 
branes and  allowing  the  licjuor  anmii  to  escape,  which  permits  the  uterine  fibers  to 
shorten  and  obtain  a  Ix'tter  grasp  on  the  child. 

Occasionally,  in  a  primipara,  the  head  will  be  deej)ly  engaged,  but  the  cervix  is 
far  back  in  the  hollow  of  the  sacrum  and  \qt\  thin.  The  membranes  are  tightly 
stretched  over  the  head,  and  there  are  no  forewaters.  By  pulling  the  cervix  gently 
to  the  middle  of  the  i)elvis,  separating  the  membranes  around  the  lower  uterine 
segment  for  two  inches,  and  jjushing  up  the  head  a  little  to  allow  some  li(iuoramnii 
to  run  down  and  nuike  a  i)ouch,  the  mechiuiism  of  lal»or  is  started  right  and  the 
pains  improve  at  once.  The  practitioner,  after  carefully  studying  the  aspects  of 
the  individual  labor,  will  have  to  select  the  remedy  which  offers  the  best  hope  of 
stinudating  the  uterus.  Internal  manipulations  should  be  avoided  as  far  as  ix>s- 
sible,  and  expectanc\'  carried  to  the  point  of  threatened  danger. 

Anomalies  of  the  Abdominal  Powers.— Weakness  of  the  abdominal  powtrs 
may  be  primary  or  secondary.  Either  the  wonuui  has  poorly  developed  abdominal 
muscles,  the  result  of  tight  lacing  or  insufficient  exi-rcise.  or  the  muscles  are  pre- 
vented from  contracting  by — (1)  Intiammatory  conditions  in  the  In-Uy;  for  ex- 
ample, appendiceal  al)scess;  (2)  hernias;  (3)  cardiac  and  pulmonary  disease  with 
dyspnea;  (4)  tumors  in  the  abdomen — fibroids,  cysts;  full  bladiler;  tympany; 
fat.  Women  with  jx^ndulous  \^c\\\  have  insufficient  abdominal  action  because  the 
tliastatic  recti  cannot  get  a  purcha.se  on  the  uterus,  which  has  fallen  forward  be- 
tween them.  Comato.se  and  narcotized  women,  the  reflexes  being  alH)lished,  lio 
not  bear  cIoanti,  but  wlvupthe  coma  is  not  deep,  the  abdominal  muscles  act  reflexly

THE    PATHOLOGY    OF   LABOR 


and  sometimes  powerfully,  as  may  be  seen  in  eclampsia  and  obstetric  anesthesia. 
PIyi)ersensitive  Avomcn  sometimes  will  refuse  to  bear  dowTi  because  it  hurts  too 
nmch,  and  in  such  cases  anesthesia  to  the  obstetric  degree,  by  abolishing  the  pain, 
will  apparently  strengthen  the  abdominal  muscles.  Sometimes  the  parturient 
actually  docs  not  know  how  to  use  the  abdominal  muscles,  and  needs  to  be  taught 
how  to  bear  doAMi  effectively.  Again,  she  bears  doA\7i  strongly  enough,  but  the 
antagonistic  muscles  of  the  pelvic  floor  contract  spasmodically  and  hold  the  head 
back.  The  woman  must  be  sho^vn  how  to  relax  the  outlet  while  bearing  do^^Ti. 
Secondarj^  weak  abdominal  action  arises  either  from  exhaustion,  the  woman  having 
used  up  her  stock  of  strength  in  fruitless  bearing-down  efforts  in  the  first  stage, 
when  they  could  do  no  good  and  much  harm,  or  the  resistances  of  the  delivery  have 
proved  too  much  for  her.  She  may  have  had  too  little  reserve  power,  or  the  weak 
uterine  contractions  have  been  unable  to  evoke  sufficiently  powerful  response  in 


Fig.  494. — Physician  Instructing  Parturient  how  to  Use  her  Powers  to  Best  Advantage. 


the  abdominal  muscles.  Voluntary  bearing-down  efforts  are  never  so  strong  nor 
so  effectual  as  those  elicited  by  the  uterine  contractions.  Curiously,  sometimes  a 
weak  uterine  pain  will  produce  a  strong  bearing-down  effort.  A  prolonged  first 
stage  is  thus  sometimes  followed  by  a  quick  second  stage,  but  in  such  cases  atony 
of  the  uterus  in  the  placental  period  is  often  to  be  anticipated. 

Prolongation  of  the  second  stage  is  the  result  of  insufficient  abdominal  action, 
and  ordinarily  neither  patient  runs  much  risk  unless  the  delay /exceeds  five  hours. 
Most  text-books  exaggerate  the  dangers  of  simple  weakness  of  the  expulsive  powers. 
This  condition  must  l)e  sharply  differentiated  from  resistant  outlet  with  strong 
pains.  Owing  to  the  pressure  exerted  by  the  head  on  the  pelvic  viscera,  fistulas  may 
possibly  result,  though  they  usually  do  not,  the  vulva  becomes  edematous  and  fri- 
able, and  aid  ma}^  have  to  be  rendered  simply  because  of  the  delay  and  the  depressing

effect  on  the  woman's  nervous  system.  For  the  diild,  such  a  stoppage  in  tlie  hihor 
may  become  (hmKcrous  from  asphyxia,  the  placental  area  being  diminished  since 
the  uterus  has  retracted;  the  caput  succedaneum  Ix'comes  very  hirge,  which,  inci- 
(h-ntally,  iiuhcates  that  the  fetus  is  sulTerint:;  from  (■erel)ral  congestion,  and  tiie  cord, 
if  it  is  ill  I  lie  pelvis,  may  sufTer  injurious  jjressure. 

Treatment.^ — First  in  the  order  of  procedun-  is  a  careful  diagnosis  of  the  cause 
of  the  delay  in  labor,  which  includes  the  determination  of  the  location,  the  station, 
or  the  degree  of  engagement  of  the  head  or  presenting  part.  Weak  uterine  contrac- 
tions in  this  stage  re(iuire  the  same  treatment  as  in  the  first  stage  (7.  r.).  In  cas<'S 
of  inllammatury  conditions  in  the  belly,  and  in  cardiac  and  respiratory  diseases,

the  woman  should  not  lu*  allow(>d  to  bear  down  too  much,  but  extraction  is  to  lie 
performeil.  Pendulous  belly  is  treatt'd  with  a  l)inder.  (Seep.  4(K).)  If  the  patient 
is  tired  out,  a  short  respite  is  given  her  by  means  of  light  ether  anesthesia,  after 
which  she  may  work  to  better  advantage.  lOther  given  to  dull  the  pain  in  the 
stretching  perineum  may  reniove  the  inhibition  on  the  alMK)minal  nmscles.  A 
change  of  i)osition  from  side  to  back,  or  back  \o  side,  or  to  tlu'  sitting  pttsture,  or 
even  a  short  walk,  may  in*  useful.  A  nuiltipara.  however,  may  not  go  far  from  the 
bed.  Ergot  is  never  to  be  given  to  stimulate  the  ut<'rus.  A  valuable  help  is  the 
instruction  of  the  i^arturient  as  to  the  best  way  to  U^ir  down,  ami  the  physician,  in 
a  sterile  gown,  may  sit  on  the  edgt'  of  the  bed,  and.  grasping  the  woman's  hands, 
with  each  pain  show  her  how  to  get  the  most  out  of  her  efl'orts  (Kig.  494).  Another 
plan  which  has  been  of  inestimable  service  in  m>  practice  is  to  i)lace  the  woman  in 


572 


THE    PATHOLOGY    OF   LABOR 


the  exaggerated  lithotomy  posture  (Fig.  495).  The  thighs  support  the  abdominal 
muscles  and  thus  strengthen  them;  any  tendency  to  pendulous  belly  is  corrected; 
the  fetus  is  straightened  out,  the  levator  ani  tightened  (which  facilitates  anterior 
rotation  of  the  occiput),  and  the  outlet  of  the  bony  pelvis  is  enlarged. 

By  putting  the  patient  in  a  squatting  Indian  attitude  against  either  a  wall  or 
the  bed,  as  King  recommends  so  highly,  the  same  results  are  o])tainable,  but  it  is 
not  so  easy  nor  so  comfortable  (Fig.  355).  A  hot  enema  may  hasten  delivery  by  un- 
loading the  bowel  and  by  stimulating  the  forces.  If  the  head  is  well  down  on  the 
perineum,  Kristeller's  expression  may  be  employed  (Fig.  496).  Both  hands  are 
evenly  spread  over  the  fundus,  and  during  the  pains  gently  applied,  but  firm  pressure 
is  exerted  in  the  axis  of  the  inlet.  As  the  contraction  of  the  uterus  diminishes,  the 
force  applied  is  to  lessen.  It  is  impractical  to  keep  up  the  pressure  between  pains. 
Kristeller's  expression  is  not  A^-ithout  dangers — rupture  of  the  uterus,  abruptio 
placentae,  injury  to  the  abdominal  viscera,  and  for  this  reason  it  should  seldom  be

used  in  multiparae,  never  when  there  is  the  least  sign  of  thinning  of  the  lower  uterine 
segment,  and  always  with  only  moderate  force. 

If  the  head  is  so  low  that  the  forehead  has  passed  the  coccyx,  Ritgen's  man- 
ceuver  may  be  used,  that  is,  pressing  the  head  out  with  two  fingers  working  from 
the  rectum.  While  the  objection  on  the  score  of  infection  could  he  removed  by  the 
use  of  rubber  gloves,  there  is  still  danger  of  injury  to  the  rectum,  and  cracks,  fissures, 
infiltrates,  bruises,  mth  subsequent  stricture,  are  to  be  considered.  By  placing  the 
two  fingers  outside,  on  the  perineum,  one  on  each  side  of  the  coccyx,  with  the  flat- 
tened rectum  between  them,  sometimes  one  can  obtain  sufficient  purchase  on  the 
forehead  to  aid  materially  in  the  deliver}^  (Fig.  497).  This  operation  may  be 
advantageously  combined  with  episiotomy.  Incision  of  the  perineum  is  a  very 
useful  operation,  and,  if  all  that  is  needed  to  complete  the  labor  is  overcoming  the 
resistance  of  the  vulvar  outlet,  episiotomy  shows  brilliant  results.  Indeed,  the 
author  often  performs  it  to  save  the  pelvic  floor  from  excessive  stretching. 

If  encouragement  and  instruction  of  the  parturient  and  the  above  measures 
fail,  forceps  are  to  be  applied,  and  easily  75  per  cent,  of  the  forceps  operations  in 
America  are  done  for  indications  of  this  nature.

The  above  remarks  apply  to  the  treatment  of  weakness  of  the  abdominal 
muscles,  when  the  second  stage  is  well  on,  and  the  head  deeply  engaged  in  the 
pelvis — even  visible  in  the  vulva.  If  the  head  is  not  engagj-d,  but  still  above  the 
inlet,  the  case  is  much  more  formidable.  What  was  said  rcgiirding  the  treatment 
of  weak  pains  in  general  api)lies  here.  Unless  the  head  can  Iw  gott<'n  to  enter  the 
pelvis  by  the  usual  means,  a  high  forceps  oi)eration  or  version  and  extraction  will 
be  required,  both  of  which  are  dangerous,  under  such  circumstances,  because  of  the 
frecjuency  and  extent  of  the  neces.sarily  inflicted  lacerations,  and  the  usually  severe 
and  sometimes  intractable  atony  of  the  uterus  j)osti)artum.  Manual  removal  of 
the  i)lacenta  i<>  often  necessitated,  which  adds  to  the  danger  of  infection.  Hof- 
meier  reconnnended  pressing  the  head  into  the  pelvis  from  the  (iutside,  using  two 
hands,  and  under  favorable  special  conditions  this  may  succeed.  The  Walcher 
j)osture  has  been  used,  but  with  only  moderate  success.  (See  Treatment  of  Con- 
tracted Pelves.)  In  some  cases  the  s(juatting  posture  favors  the  i)a.ssage  <jf  the

delivery  be  imperatively  demaniled,  all  jin-parations  must  be  made  to  avoid  the 
above-named  dangers. 

Myoclonia  Uteri,  or  Cramp  Pains. — When  the  action  of  the  uterus  is  irregular, 
painful,  and  iiiedicjrnt,  even  thouiili  the  force  api)arently  exerted  is  normal  or  t'ven 
greater  than  normal,  we  speak  of  cramp  pains  or  myoclonia  uteri.  The  condition 
is  closely  allied  to  tetanus  or  spasmus  uteri,  al)out  to  In?  consideretl.  I^idmr  is  very 
painful  and  prolonged;  the  women  feel  that  the  pains  do  no  gcHxl.  and  iK'come 
nervous,  highly  exeit(>d.  and  sometimes  even  delirious.  The  constant  sufTering, 
with  inappreciable  progn\>vs  in  the  labor,  throws  the  parturient  into  a  sort  of  frenzy. 
In  the  second  stage  thes(>  pains  are  of  less  significanec,  but  if  the  first  stage  was  much 
prolonged,  atonia  uteri  may  have  resulted  and  artificial  delivery  may  Ik*  needed 
becau.so  labor  has  stopjM'd.  The  danger  of  cramp  pains.  Ix'sides  their  bad  eflfect  on 
the  morale  of  the  jxirturient.  lies  in  asphyxia  of  the  child,  and  in  the  jiossible  in- 
juries and  infections  from  the  oiK-rations  rend«'red  necessary  by  the  delay.  Cases 
of  real  myoclonia  uteri  are  rare:   most  of  them  are  in.stances  of  strictura  uteri. 

Tetanus  Uteri;    Strictura  Uteri. — When  the  utenis  passes  into  a  state  of  tonic

contraction,  we  speak  of  tetanus  uteri.  If  the  spasm  involves  only  one  zone  of  the 
organ,  the  term  strictura  uteri  is  applied.  Older  writers  believed  the  condition  was 
frequent,  and  called  it  hour-glass  contraction  of  the  uterus.  Jaggard  denied  its 
existence,  but  there  is  no  doubt  that  it  occurs,  and,  in  the  author's  experience,  not 
rarely.     A  spasm  of  the  external  os  is  also  described,  but  this  is  very  uncommon. 

The  causes  of  cramp  pains,  tetanus,  and  strictura  are  much  alike,  an  unstable 
nervous  system  being  the  most  frequent  predisposing  factor.  Locally,  any  irritant 
to  the  cervix  or  uterine  wall  will  evoke  tempestuous  action,  for  example,  too  fre- 
quent examinations,  especially  if  combined  with  attempts  to  dilate  the  cervix; 
chronic  metritis  and  cervicitis;  the  improper  use  and  application  of  hydrostatic 
bags;  premature  attempts  at  delivery  through  an  ill-dilated  cervix;  irritation  of 
the  uterine  wall  by  the  hand,  bougies,  douches;  and  rupture  of  the  membranes  and 
escape  of  the  liquor  amnii,  which  permit  the  uterine  wall  to  apply  itself  too  firmly 
on  the  irregular  and  knol^by  fetal  body.  It  will  be  noticed  that  the  remedies  recom- 
mended for  the  treatment  of  atony  of  the  uterus  may  send  the  organ  into  tempestu- 
ous action  or  cause  stricture.  Ol^structed  labor  produces  a  condition  analogous  to 
tetanus  uteri,  but  here  the  uterus  is  moderately  firm  all  the  time,  and  the  contrac- 
tions are  regular  and  powerful — sometimes  sufficiently  so  as  to  burst  it.  A  uterus  in 
tetanic  spasm  will  not  rupture,  but  operations  undertaken  during  the  contraction 
will  tear  it  if  too  much  force  is  used.     (See  Contracted  Pelvis.) 

Ergot,  in  the  olden  times,  was  frequently  responsible  for  tetanus  uteri,  but 
now,  since  it  has  been  discarded  as  the  result  of  alm-ost  universal  condemnation  by 
obstetric  authorities,  one  rarely  meets  such  a  case,  except  perhaps  in  the  practice 
of  midwives. 

Tetanus  uteri  completely  stops  labor;  the  woman  complains  of  continuous 
pain;  the  child  dies  as  the  result  of  asphyxia,  the  contracted  uterus  preventing  the 
oxj'genation  of  the  fetal  blood,  and  soon,  because  of  the  same  circulatory  disturb- 
ance, infection  of  the  uterus  and  contents  occurs.  When  sepsis  begins,  the  pulse 
and  temperature  mount  rapidly,  the  skin  becomes  dry,  the  face  cyanotic  or  reel,  and 
great  tenderness  in  and  around  the  uterus  is  noticeable.  The  liquor  amnii  takes  on 
a  bad  odor,  is  discolored, — a  cloudy  green  or  gray, — the  vulva  reddens  and  swells, 
while  any  abrasions  on  the  labia  become  covered  with  a  gray  exudate.  Gas  may 
accumulate  in  the  uterus,  paralyzing  it,  after  which  the  organ  balloons  out — that 
is,  tympania  uteri  develops.  In  such  cases  the  bacterium  coli  is  usually  found. 
Unless  relief  is  brought,  the  woman  dies  of  sepsis  or  exhaustion,  or  both. 

Strictura  Uteri. — A  spasm  of  a  zone  of  circular  fibers  of  the  uterus  maj'  imprison 
the  fetus.  Sometimes  the  constriction  is  around  the  child's  neck,  as  in  Fig.  498, 
and  sometimes  around  the  trunk  or  breech,  a  groove  around  the  arms  and  chest 
having  been  demonstrable  in  a  case  delivered  at  the  Chicago  Lying-in  Hospital. 
Ordinarily,  the  contraction  of  the  remainder  of  the  uterus  is  not  strong  enough 
to  rupture  the  lower  uterine  segment,  which  is  in  spasm,  nor,  indeed,  to  overcome  the 
resistance  of  the  constricting  ring.  Therefore  labor  comes  to  a  standstill,  and  we 
find  the  same  clinical  picture  as  in  tetanus  uteri  {q.  p.),  though  not  so  aggravated  nor 
so  quickly  fatal.  The  contractions  are  irregular  both  in  frequency  and  in  strength, 
are  very  painful,  and  the  woman  is  frenzied  by  the  delay  in  labor  in  spite  of  con- 
stant and  prolonged  suffering.  The  lower  part  of  the  uterus  is  hard,  the  fundus 
soft  (between  pains),  and  the  lower  abdomen  is  very  tender.  Attempts  at  version 
may  be  rendered  futile  by  the  stricture  if  they  do  not  rupture  the  uterus.  In  one 
of  my  cases  the  whole  fetus  was  locked  in  above  the  stricture,  which  was  so  narrow 
that  I  could  not  insert  more  than  three  fingers  (Fig.  499). 

Strictures  are  oftenest  found  in  primiparse  of  neurasthenic  type  and  in  women 
in  whom  the  bag  of  waters  ruptures  early  in  labor.  After  a  while  progress  ceases,

but  the  occiput  turns  (juickly  l);i(k,  as  on  a  pivot,  the  slioulders  l>eing  locked  in 
position  by  tiie  uterine  spasm. 

In  the  tiiird  stage,  strictura  uteri,  or  iKJur-glass  contraction,  is  of  great  sig- 
nificance, being  a  frequent  cause  of  postpartum  licmorrliage  with  incarceration 
of  the  phicenta,  and  even  producing  anomahes  of  uterine  contraction  after  the 
placenta  is  delivered. 

Diaono.sis. — Tetanus  uteri  is  easily  determined  from  the  board-like  consistence 
of  the  organ,  the  continuous  pain,  and  suspenderl  labor.  Spasm  of  Bandl's  ring 
is  suspected  in  all  cases  of  cramp  i)ains,  irregular  and  i)ainful  uterine  action,  ex-

can  be  positively  diagnosed  oidy  when  the  ring  is  palpabh*  internally  or  abdominally. 
Tetanus  uteri  nuist  l)e  dilYerentiated  from  the  simple  emptying  of  the  organ  of  the 
li(luor  anmii  and  the  i)assive  application  of  its  walls  to  the  child.  In  tetamis  the 
uterus  is  very  hard,  ovoid,  and  tlu'  fetal  i)arts  are  not  palpable,  while  the  haml  intro- 
duced from  below  can  only  with  the  greatest  difficulty,  ami  sometimes  only  with  the 
ri.sk  of  a  rupture  of  the  wall,  be  ])as.sed  up  to  the  fun«lus.  In  simple  retraction  the 
uterine  wall  is  firm  but  i)lial)l«\  the  uterus  has  the  shape  of  the  fetus,  and  varies  ac- 
cording to  the  attitude  of  the  latter;  fetal  parts  are  readily  felt,  and  the  hand  is

obstructed  labor,  the  child  being  delivered  largely  into  the  lower  uterine  segment, 
the  contracting  and  retracted  fundus  uteri  ma}^  be  thought  to  be  in  tetanus.  Here 
the  shape  of  the  tumor,  the  hard  fundus,  the  soft,  thUited  lower  uterine  segment, 
regularly  recurring  pains,  and  the  internal  exploration  will  clear  the  diagnosis. 

Treatment. — Irregular  and  cramp  pains  and  stricture  of  the  uterus  require 
sedatives,  first  among  which  is  the  influence  of  a  confident  and  capa])le  physician 
and  nurse.  Proper  encouragement  will  help  the  nervous,  excited  woman  to  become 
quieted.  A  prolonged  hot  bath,  followed  by  a  hot  drink  of  lemonade  containing  3 
drams  of  alcohol,  will  often  be  productive  of  gentle  perspiration,  sleep,  and  calm. 
Early  in  the  first  stage  a  small  dose  of  morphin  may  be  given.  Sodium  bromid  up 
to  60  grains  may  be  exhiliited,  but  chloral  at  all  times  and  morphin,  except  as  above 
stated,  are  dangerous,  the  first  because  of  its  cytolytic  influence  on  the  liver,  the 
latter  because  of  its  narcotic  effect  on  the  baby.     Green,  of  Boston,  recommends

scopolamin-morphin  for  the  nervous,  apprehensive  parturient.  Change  of  posi- 
tion from  back  to  side,  the  elevated  Sims,  or  the  knee-chest,  and  walking  about  may 
be  tried.  Prolonged  warm  salt  solution  douches  are  sometimes  useful.  The  vagina 
is  filled  with  the  solution,  the  labia  held  together  for  a  few  minutes,  and  then  the 
water  is  allowed  to  escape,  such  a  procedure  being  repeated  for  thirty  minutes  at  a 
time.  Vaginal  examinations  are  restricted,  and  all  attempts  to  chlate  the  cervix 
omitted. 

If  the  uterus  is  tetanically  contracted,  it  will  seldom  respond  to  the  above 
treatment  and  delivery  is  indicated.  A  prime  requisite  for  any  and  all  intra- 
uterine manipulations  in  tetanus  uteri  is  jirofound  anesthesia.  Ether  is  to  be 
preferred  because  the  patient  must  ])C  l)rought  close  to  the  danger-line  of  narcosis, 
and  the  operation  must  not  be  begun — not  even  the  hand  introduced  until  the  uterus 
has  relaxed.     In  very  rare  instances  a  prolonged,  deep  chloroform  narcosis  failed

to  quiet  the  uterus;    delivery  from  below  jjnjved  impcjssiljle,  and  cesarean  section 
had  U)  be  perforiiicd. 

Spasm  of  the  Cervix;  Strictura  Cervicis. — Many  authors  den\  lin-  .xistence 
of  si)asiM()(lic  rif^idity  of  the  cervix.  Fieux  j)r(>ved  that  there  are  practically  no 
muscular  fibers  in  the  cervix  around  the  external  os  near  term.  Nevertheless,  a 
few  cases  in  the  author's  experience  have  shown  that  occasionally  the  cervix  will 
contract,  either  in  front  of  the  presenting  part  or,  more  commonly,  around  the  neck 
after  the  head  is  through  it,  or  after  the  body  is  tlelivered  in  breech  presentation, 
and  thus  create  an  obstacle  to  delivery.  Most  of  the  cases  of  so-called  rigidity 
of  the  cervix  are  not  spasmodic,  but  anatomic,  due  to  mmw  alteration  of  structure. 
The  causes,  diagnosis,  and  treatment  are  on  the  same  lines  as  those  of  stric- 
tura uteri.  Stricture  of  the  cervix  around  the  after-coming  head  is  often  more 
apparent  than  real,  though  the  effect  is  serious,  just  the  same.  The  sh'nder  IwKly 
slips  through  the  unprepared  cervix,  but  the  head  is  arrested.  Such  a  cervix,  not 
dilating  with  gentle  elTorts,  ina\'  have  to  l)e  incise(l. 

Precipitate  Labors — Too  Strong  Pains. — Too  strong  uterine  action  and  too 
strong  abdominal  action  are  sometimes  observed,  and  they  lead  to  the  too  rapid 
delivery  of  the  child.  Since  the  abdominal  action  is  mostly  reflexly  excited  by  the 
uterine  pains,  when  the  latter  are  strong,  the  former  will  also  be  strong.  Then,  too, 
even  after  long  labor,  the  first  stage  having  been  very  slow,  characterized  by  either 
atonia  or  myoclonia  uteri,  when  the  heatl  finally  has  reached  the  perineum,  its 
presence  here  may  evoke  such  powerful  abdominal  action  that  labor  is  finished 
entirely  too  fjuickly. 

Precipitate  labor  is  the  forcible,  violent  expulsion  of  the  child  in  a  period  of  time 
disproportionate  to  that  normally  recjuiretl  for  the  safe  overcoming  of  the  resis- 
tances. Sometimes  the  woman  has  pains  for  several  hours,  but  does  not  recognize 
them  as  true  labor  pains,  and  sends  for  the  accoucheur  too  late.  These  labors 
should  not  be  called  i)recipitate.  Many  cjises  are  on  record  where  the  uterus, 
without  warning,  suddenly  became  violently  active  and  expres.sed  the  child  in  a 
few  minutes  to  an  hour.  The  woman  may  be  thus  overtaken  on  the  street  and  not 
have  time  to  run  to  shelter.  In  her  excitement  she  may  forget  to  lie  down,  and  the 
child  may  fall  to  the  ground,  the  cord  breaking.  In  a  case  in  the  dispen.sary  service 
of  the  ('liicago  Lying-in  Mosjiital  the  mother  was  lying  down  and  the  child  wa.s 
hurled  against  the  foot  of  the  bed,  the  cord  breaking,  l)Ut  the  child  wa.<  not  injured. 
In  another  from  the  same  service  the  child  fell  to  the  floor  and  died  from  a  fractured 
skull.  Very  important  are  these  cases  from  a  medicolegal  point  of  view,  since  the 
mother,  if  she  was  delivered  alone,  may  be  accused  of  having  killed  the  child.  The 
best  authorities  ( Freyer)  are  now  agreed  that  the  excitement  and  pain  inciilent  to 
such  an  event  can  protluce  a  state  of  mental  al)erration  which  may  persist  during  the 
last  few  minutes  of  labor,  and  for  a  variable  period  after  it,  certainly  long  enough 
for  the  child  to  drown  in  the  mass  of  blood,  feces,  urine,  liquor  amnii,  and  meco- 
nium, in  which,  mvhUt  such  circuinstanc  es,  it  is  likely  to  be  born.  The  actual  causes 
of  too  strong  pains  and  precipitate  labor  are  not  known.  Heredity,  habit,  neuras- 
thenia, multiparity,  large  pelvis,  small  child,  cervicitis,  and  old  cervical  and  perineal 
lacerations  have  been  cited  as  predisposing  factors.  Various  uteri  have  varying 
contractile  power^u.st  as  uwu  have  greater  or  less  musculature  and  better  or 
wprse  muscle,  and,  usually,  the  conduct  of  the  uterus  in  a  given  labor  may  Ik'  an- 
ticipated to  be  like  its  action  in  previous  deliveries. 

Dangers  of  Precipitak  Labor.—  Fortunately,  these  are  not  .so  great  as  one  would 
expect.  In  the  author's  experience  these  accidents  have  occurred:  complete  and 
incomplete  lacerations  of  the  perineum,  clitoris  tears,  laceration  of  the  cervix, 
postpartum  hemorrhag*-.  rupture  of  the  uterus  with  fatal  hemorrhage,  puerperal 
sepsis,  fracture  of  the  child's  skull,  intracranial  hemorrhag»'.  drt)wning  of  twins  in 
the  discharges,  and  rupture  of  the  cord.  It  must  be  sjiid  that  these  arc  very  rare,

with  the  exception  of  mikl  and  moderately  severe  perineal  tears,  and  represent 
isolated  instances  from  private  practice  and  the  large  service  of  several  hospitals. 
Other  authors  have  noticed  postpartum  hemorrhage,  but  not  fatal,  emphysema  of 
the  neck,  fracture  of  the  sternum,  hsematoma  vulva?.  Hirst  records  an  instance  of 
marvelous  endurance  on  the  part  of  the  infant.  A  woman  on  an  express  train 
going  40  miles  an  hour  dropped  the  infant  through  the  water-closet,  and  it  was  picked 
out  of  the  snow  an  hour  later,  alive  and  uninjured.  A\'inckel  records  20  children 
delivered  in  winter  and  exposed  for  hours  without  harm.  These  facts  are  excep- 
tional— many  children  have  died  from  cold  and  injury. 

Treatment. — If  the  pains  are  coming  on  tempestuously,  one  following  the  other 
in  rapid  succession,  the  woman's  face  becoming  turgid,  and  the  bearing-down  efforts 
prolonged  and  powerful,  the  accoucheur  must  do  something  to  prevent  the  too  rapid 
expulsion  of  the  child  and  the  injury  to  the  soft  parts.  The  patient  is  to  be  turned 
on  the  side,  and  ether  given  until  the  uterine  action  has  moderated.  Admonitions 
to  the  woman  to  not  bear  down  are  usually  useless,  because  she  cannot  help  it.  If 
the  head  is  coming  through  the  vulva  in  spite  of  mild  measures,  it  should  be  allowed 
to  come.  Under  no  circumstances  should  an  attempt  be  made  forcibly  to  hold  the 
head  back  with  a  view  to  saving  the  perineum.  The  danger  of  rupture  of  the  uterus 
thus  arises,  the  conditions  thus  artificially  produced  resembling  obstructed  labor. 
Episiotomy  is  to  be  performed  if  there  is  time.  Care  is  to  be  exerted  to  save  the 
rapidh^  emerging  child  from  injury.  After  precipitate  labors  it  may  be  necessary 
to  make  an  internal  examination  to  find  if  there  are  deep  injuries.  External  and 
internal  hemorrhage  and  the  general  aspects  of  the  case  will  decide  this  point.  In 
cleaning  up  a  case  where  the  child  has  been  delivered  without  the  usual  aseptic 
preparations,  the  open  vulva  is  to  be  treated  on  the  same  principles  as  a  compound 
fracture.  A  physician  called  in  emergency  to  a  partus  praecipitatus  should  not 
express  the  placenta  unless  there  be  hemorrhage,  but  should  institute  proper 
arrangements  for  the  conduct  of  the  third  stage,  or  provide  for  the  transportation 
of  the  patient  to  a  hospital  or  home.  Pending  the  arrival  of  the  woman's  own 
accoucheur,  he  should  do  only  that  which  is  absolutely  necessary  for  the  safety  of 
the  mother  and  child,  and  should  turn  the  case  over  to  him  upon  his  arrival.

ANOMALIES  OF  THE  PASSENGERS 

Classification. — Under  tliis  caption  are  to  be  considered  irregularities  of  the 
meciiani.siii  ol  laljor  due  to  the  child.  While  those  due  to  the  phicenta  might  belong 
here,  it  is  best  to  take  them  up  with  the  stuily  of  i)ostpartuni  ln'morrhage,  Antmm- 
lies  of  the  niechanism  of  lal)or  are  due  to  errors  of  attitude,  (jf  j)res<-ntation,  and  of 
position  of  the  child,  and  also  to  the  overgrowth  of  the  fetal  ixxly  as  a  whole  or  as 
a  part.  Before  taking  up  this  branch  of  the  subject  the  student  is  a<lvised  to  read 
what  was  said  a!x)ut  the  niechanism  of  normal  labor,  for  the  following  pages  will 
deal  mainly  with  descriptions  of  the  factors  of  labor  gone  wrong.  For  (juick  and 
clear  orientation  regarding  the  relations  of  the  fetus  to  the  mother,  and  tlie  various 
movements  executed  in  the  mechanism  of  lal)or,  a  pelvis  and  f<'tal  head  are  almost 
absolutely  necessary,  though  the  little  models  and  paper  manikins  on  the  market 
will  aid  very  much.  It  is  also  necessary'  to  have  clear  notions  regarding  the  terms 
usetl  in  describing  all  phases  of  the  subject. 

".\ttitude"  or  ])()sture  means  the  relation  of  the  jiartsof  the  fetus  to  eacii  other; 
"presentation"  is  the  part  of  the  fetus  which  lies  over  the  os,  or  is  bounded  by  the 
girdle  of  resistance,  and  "position"  means  the  relation  of  any  given  arbitrary  point 
in  the  jiresenting  jiart  to  the  four  ciuadrants  of  the  mother's  pelvis.  The  name  of 
this  arbitrary  point  is  the  "point  of  direction."  It  might  also  be  called  the  "de- 
nominator." To  a  certain  extent  attitude  determines  j)resentation;  f(^r  example, 
when  the  head  lies  over  the  inlet,  not  in  its  u.sual  condition  of  Hexion,  but  with  the 
chin  extended,  face  presentation  results.  If  the  head  is  less  deflexed,  brow  presenta- 
tion, and  if  only  jiardy  deflexed,  tho  vertex  being  felt  over  the  os,  median  vertex 
presentation  is  (hagnosed.  These  might  be  groui)eil  together  as  "deflexion  at- 
titudes." In  addition  to  these,  the  result  of  errors  of  attitude,  there  are  abnormal 
presentations  produced  l)y  errors  of  polarity  of  the  fetus,  such  as  breech  and  shoulder 
presentation.  Other  anomalies  of  attitude  are  prolapse  of  the  feet  in  breech  pres- 
entation, of  the  arm  in  head  presentation,  of  the  cord  in  all  presentations,  etc. 
Just  as  in  occipital  j^resentations,  each  of  the  abnormal  j)resentations  may  lie  in 
different  positions.  Following  Baudeloccjue  and  Hodge,  six  jx)siti()ns  were  dis- 
tinguished in  occipital  presentations— O.L.A.,  O.L.T.,  O.L.P.,  O.D.A.,  O.D.T., 
O.D.P. — and  six  may  be  tlescribed  for  most  of  the  abnormal  jjresentations,  though 
not  all  are  ol)scrve(l  in  practice;  for  exami)le,  Sac.L..\.,  S.L.T.,  S.L.P.,  S.D.A., 
S.n.T.,  and  S.D.F.  In  l)reech  presentation  S.L..\.  and  S.D.P.  an'  the  ones  almost 
exclusively  observetl. 

Finally,  errors  in  rotation  of  the  jiresenting  jiart  ticcur;  eitiier  rotation  ceases 
before  its  completion,  or  the  presenting  i)art  turns  i)ackward  into  the  sacrum.  cau!<- 
ing  severe  dystocia.  It  is  thus  evident  that  an  almost  infinite  variety  of  combina- 
tions of  presentations  and  errors  of  attitude  and  i)osition  niay  l)e  presented  to  the 
accoucheur  for  study,  and  when  it  is  considered  that,  in  addition,  a  contracted  jx'lvis, 
a  large  child,  twins,  or  monsters  may  coexist,  not  to  mention  all  suix^radded  com- 
plications incidental  and  accidental  to  parturition,  one  must  concede  that  truly 
formidal)lf  |)roM(ins  of  (jrcp  ((Hiipli'xit  y  are  offered  for  solution. 

Unusual  Mechanisms  of  Head  Labors. — In  order  will  Ih'  discu.s.><ed  errors  of 
rotation  in  occipital  presentations  and  the  deflexion  attitudes — metlian  vertex, 
forehead,  brow,  and  face  i>res(>ntation.

580  THE    PATHOLOGY    OF   LABOR 

Persistent  Occipitoposterior  Position. — Xormally,  when  labor  starts  with 
O.D.P.  or  O.L.P.,  anterior  rotation  occurs,  and  ,,the  delivery  terminates  as  in 
O.L.A.  and  O.D.A.  Sutugin,  of  Russia,  believes  that  in  the  majority  of  cases  the 
head  enters  the  pelvis  in  the  transverse  diameter,  which  agrees  with  my  experience. 
After  it  has  passed  the  inlet  the  occiput  turns  either  toward  the  front  or  the  back — 
almost  always  toward  the  pul)is.  Should  the  occiput  turn  toward  the  sacrum,  or 
should  the  head  enter  the  pelvis  in  an  oblique  with  the  occiput  behind,  an  occipito- 
posterior position  results.  In  rare  instances  the  head  may  enter  the  pelvis  with 
the  occiput  pointed  directly  behind,  or  the  occiput  may  rotate  into  the  hollow  of  the 
sacrum  after  engagement.  These  are  called  occipitosacral  positions,  and  will  be 
considered  later. 

In  still  rarer  instances  the  head  enters  and  passes  through  the  pelvis  with  the 
occiput  directly  anterior,  and  no  rotation  is  needed  in  the  mechanism  of  its  delivery. 
Prolapse  of  an  arm  was  the  cause  of  this  anomaly  in  the  one  instance  the  author 
observed. 

Since,  in  the  large  majority  of  cases  of  occipitoposterior  position,  anterior  ro- 
tation finally  occurs,  a  search  into  the  cause  of  its  persistence  is  necessary:  (a)  Flat 
pelvis  in  minor  degrees,  the  occiput  meeting  resistance  first  and  deflexion  occurring; 
(6)  primary  brachycephalia,  the  two  head  levers  being  of  the  same  length  antl  flexion 
not  occurring;  (c)  pendulous  abdomen,  the  convex  back  of  the  fetus  fitting  better 
to  the  posterior  arched  wall  of  the  uterus;  (c/)  large  pelvis,  small  child,  the  natural 
mechanism  of  labor  of  balanced  resistances  becoming  inoperative;  (e)  prolapse  of 
an  arm  in  front  of  the  occiput — if  it  lay  behind  the  occiput,  anterior  rotation  would 
be  facilitated;  (/)  anything  tliat  would  mechanically  prevent  anterior  rotation  of 
the  head,  or  that  would  hold  back  the  child's  trimk  and  thus  keep  the  ])ack  posterior, 
for  example,  the  placenta,  tumors  in  the  wall  of  the  uterus,  scars  in  the  uterus  which 
give  the  lower  uterine  segment  an  irregular  shape,  a  full  rectum  or  bladder,  etc.; 
(g)  exhaustion  of  the  powers  before  rotation  has  been  completed;  in  such  cases 
"arrest"  of  rotation  occurs  at  any  point  in  the  transit  of  the  occiput;  (h)  vices 
of  configuration  of  the  bony  pelvic  cavity,  for  example,  poorly  developed  spines  of 
the  ischia — fumiel  pelvis;  (^)  abnormal  pelvic  floor,  which  gives  a  wrong  bend  to 
the  parturient  canal  or  does  not  form  a  good  gutter.  Not  all  the  causes  are  known 
or  understood.  Given  a  cause,  the  child  soon  becomes  molded  to  the  abnormal 
position,  the  uterus  adapts  itself  to  the  child,  and  the  condition  is  less  easily  cor- 
rected as  labor  goes  on. 

Course. — Two  varieties  are  distinguishable:  first,  those  where  the  head  re- 
mains high  up  and  will  not  engage,  and  those  where  the  head  enters  the  pelvis  with 
the  occiput  behind.  In  the  first  class,  which,  fortunately,  are  rare,  labor  comes  to 
a  standstill,  and  occasionally  a  brow  presentation  develops,  a  little  deflexion  occur- 
ring. In  the  second  type  the  occiput  sinks  in  either  the  transverse  or  one  of  the 
obliques,  and  comes  to  the  second  parallel  plane  of  Hodge.  Now  four  terminations 
are  possible:  (1)  Under  strong  pains  the  occiput  sweeps  forward  through  the  135 
degrees  and  comes  to  lie  under  the  pubis  (commonest) ;  (2)  it  comes  forward  more  or 
less,  usually  to  the  transverse  diameter,  and  stops — "deep  transverse  arrest";  (3)  it 
may  come  down  in  the  transverse,  and  the  head  may  even  be  delivered  in  the  trans- 
verse, the  occiput  rolling  out  under  one  of  the  descending  rami  pubis;  (4)  it  may 
rotate  backward  to  the  hollow  of  the  sacrum,  becoming  an  occipitosacral  position. 
•  If  the  head  rotates  l^ackward  into  the  sacrum,  nature  manages  the  deliver}-  in  two 
ways:  First,  extreme  flexion  occurs,  and  the  pains  force  the  head  downward  and 
backward  against  the  perineum,  which  is  much  overstretched  and  nearly  always 
torn;  descent  is  continued  until  the  forehead  stems  behind  the  pubis  and  the  oc- 
ciput has  escaped  either  over  or  through  the  torn  perineum,  the  perineal  region 
coming  to  lie  on  the  nape  of  the  neck;  now  the  face  appears  from  behind  the  pubis, 
extension  occurring  (Fig.  500).     Secondly,  as  the  head  descends  deflexion  occurs,

and  now  the  occiput  appears  over  the  perineum,  which  is  more  endangered  than  in 
the  first  instance;  lastly,  the  face  comes  from  behind  the  jjubis  (Fig.  oOl ).  In  this 
form  it  is  almo.^t  impossible  clinically  to  ditTerentiate  the  mechanism  from   that

of  brow  presentation.     External  rotation  or  restitution  of  the  occiput  to  the  rear 
is  the  rule,  the  face  looking  upward,  but  when  the  shoulders  start  to  come,  they

usually  descend  in  an  oblique  or  even  in  the  sagittal  diameter,  and  then  the  face 
turns  slightly  toward  one  side. 

]\Iolding  of  the  head  with  the  first  mechanism  is  that  of  extreme  doliehoccphaly 
(Fig.  502),  the  occiput  being  more  than  usually  pointed,  while  with  the  second 
mechanism  the  shape  of  the  head  resembles  more  that  of  the  brow  presentation 
(Fig.  503).  In  multiparse  naturally  the  head  does  not  suffer  as  much  distortion  as 
in  primiparse.  The  caput  succedaneum  in  the  first  mechanism  is  found  over  the 
sagittal  suture,  anterior  to  the  small  fontanel;  in  the  second  mechanism  it  lies  over 
the  large  fontanel.     Lateral  asymmetry  of  the  head  is  usually  absent. 

Clinical  Course  and  Diagnosis. — In  occipitoposterior  positions  labor  is  generally 
slower  and  longer,  the  pains  being  weak  and  irregular  both  as  to  time  and  as  to 
strength.  Such  pains  may  serve  to  draw  the  accoucheur's  attention  to  the  condi- 
tion. Early  rupture  of  the  bag  of  waters  is  frequent,  and  in  general  things  do  not  go 
smoothly.     The  head  stays  high  up  longer  than  in  anterior  positions,  requires

stronger  pains  to  bring  it  well  down  in  the  pelvis,  and,  after  anterior  rotation  has 
started,  the  uterus  and  abdominal  pressure  may  prove  unequal  to  the  task  of  forcing 
the  head  all  the  way  round,  labor  coming  to  a  standstill  with  arrested  rotation. 
Dilatation  of  the  cervix  is  incomplete  because  the  head  does  not  fit  well  into  the 
pelvis,  and  it  does  not  press  equally  on  the  internal  os  all  around.  Spontaneous 
delivery  in  occipitoposterior  positions  requires  great  uterine  and  abdominal  effort, 
because — (1)  The  head  traverses  the  pelvic  floor  with  its  largest  cUameters.  Instead 
of  the  small  suboccipitobregmatic  and  suboccipitofrontal  planes,  the  occipitofrontal 
and  the  occipitomental  planes  pass  through  the  vulva.  (2)  When  the  chin  is  strongly 
flexed  on  the  sternum,  the  nape  of  the  neck  is  stretched  and  the  child  forms  a  solid, 
unbendable  cylinder,  which  cannot  accommodate  itself  to  the  angular  birth-canal. 
The  birth-canal,  therefore,  has  to  either  stretch  or  tear,  to  allow  the  cylinder  to  pass 
through.  (3)  The  back  and  the  head  have  to  pass  through  the  pelvis  together 
(Fig.  500).     Perineal  lacerations  are  the  rule  unless  the  child  is  small  or  the  woman

multiparous.  They  are  ilue  to  the  fact  that  tlie  liead  passes  through,  i)resenting 
larger  i)hines  than  usual,  and  also  to  the  fact  that  the  perineum  is  much  and  forcibly 
disloeatetl  downward — torn  olT,  in  fact,  from  its  hony  and  vaginal  attachments. 

Abdominally,  in  tliin  women,  the  diagnosis  may  s<jmetimes  Ik*  made  l)y  a 
glance — over  the  pubis  there  is  a  distinct  hollow.  Palpation  reveals  the  shoulder 
far  back  from  the  median  line,  and  the  forehead  can  usually  Ix"  felt  over  the  op- 
posite ramus  pubis.  The  heart-tones  are  deep  in  the  flank  and  distant  from  the  ear, 
although  if,  as  sometimes  occurs,  there  is  a  moderate  deHexion  of  the  head,  the  chest 
is  pushed  forward  against  the  abdominal  wall  and  the  heart-tones  are  very  loud  and 
distinct.  They  are  then  on  the  same  side  as  the  forehead,  opposite  to  that  on  which 
the  back  may  be  felt,  and  this  finding  may  give  rise  to  erroneous  diagnoses  of  face 
presentation  or  of  occiput  presentation,  the  accoucheur  believing  the  occiput  is  on 
the  side  other  than  the  one  truly  present.  Internally,  early  in  lal)or  the  head  is 
felt  high  up,  usually  partly  deHexed,  the  small  fontanel  being  higher,  or  on  a  level 
with  the  large,  which  is  nearer  the  center  of  the  pelvis.  Unless  the  ix'lvis  is  con- 
tracted or  the  belly  pendulous,  the  head  is  synclytic.  If  anterior  rotation  is  going 
to  occur,  flexion  takes  place  with  descent.     The  palpating  finger  will  discover  the

tendency  of  the  small  fontanel  to  turn  to  the  front  during  the  pains,  or  will  find  it 
easy  to  push  the  occiput  in  this  direction.  If  posterior  rotation  is  to  Ik*  the  mech- 
anism, the  heat!  descends  in  moderate  extension,  this  attitude  of  the  child  having 
been  called  "military,"  that  is,  the  head  is  set  squarely  on  the  shoulders.  As  the 
occiput  turns  into  the  hollow  of  the  sacrum,  the  finger  feels  the  small  f«»ntanel 
deeply  on  the  rectum,  and  the  large  one  behind  the  pubis,  the  sagittal  sutun-  running 
nearly  anterojiosteriorly  and  from  above  forward,  downward,  and  backward.  If 
the  first  mechanism  of  delivery,  that  of  extreme  flexion,  is  the  one  .selected  by  nature, 
the  large  fontanel  is  felt  just  under  the  pubis;  if  the  second,  that  of  extension,  the 
large  fontanel  lies  in  the  center  of  the  pelvis,  and  the  glalx'lla  will  Im'  felt  In'hind  the 
pubis  (Kigs.  o()4  and  oO'y).  Owing  to  the  usually  large  caput  succedaneum,  it  is 
not  always  easy  to  outline  the  sutures,  and  under  thes<*  difficulties  the  finger  is  to 
l>e  pa.'^.sed  to  the  side,  until  the  ear  is  found,  when  the  direction  of  the  tragus  will 
bring  clarity.  Not  seldom  the  accoucheur  is  surprised  by  the  head  U'lng  delivered 
with  the  occiput  over  the  i>erineum,  when  he  was  anticipating  a  normal  mechanism. 
Prognosis. — Mortality  and  morbidity  are  higher  for  both  mother  and  child  in 
occipitoposterior  positions.  For  the  mother,  exhaustion  and  sepsis  from  prolonged 
labor,  and  the  frequently  necessary  operations,  with  the  almost  inevital)le  lacera- 


584  THE    PATHOLOGY    OF   LABOR 

tions,  are  to  be  feared.  Postpartum  hemorrhage  from  secondary  inertia  uteri  is 
not  rare.  For  the  child,  asphyxia  and  the  operative  deUvery  ])ring  danger,  and 
without  doubt,  in  the  author's  opinion,  more  children  are  lost  from  this  complica- 
tion than  are  lost  from  the  effects  of  contracted  pelvis. 

Treatment. — When  the  head  is  high,  "floating"  above  the  pelvis,  "caput 
ballitabile,"  it  is  best  not  to  interfere.  A  complete  examination  is  to  ])e  made  to 
determine  the  existence  of  a  contracted  pelvis  or  other  anomaly  which  may  require 
treatment  for  its  OAvn  sake,  and  also,  if  possible,  the  cause  of  the  occipitoposterior 
position.  During  the  usually  prolonged  first  stage  the  woman  should  walk  around, 
and  when  lying  down,  should  recline  on  the  side  on  which  the  occiput  lies.  By  this 
means  the  breech  is  thrown  over  to  the  side,  the  spinal  column  is  straightened,  the 
occiput  is  forced  doA\ai,  flexion  increased,  and,  therefore,  rotation  favored.  Some- 
times a  change  to  the  side  position  will  strengthen  uterine  action.  Rupture  of  the 
bag  of  waters  retards,  rather  than  hastens,  labor  in  these  positions,  both  by  inter- 
fering with  the  mechanism  of  lal:>or  and  by  removing  the  hydrostatic  cervical  dilator, 
and  besides  loss  of  the  liquor  amnii  makes  version,  if  the  case  comes  to  it,  much 
more  difficult  or  even  impossible.  Watchful  expectancy  is  the  treatment  until  an 
indication  for  interference  arises.  If  the  labor  drags  on,  and  clanger  to  either 
mother  or  child,  while  not  imminent,  is  to  be  anticipated,  dilatation  of  the  cervix 
may  be  hastened  l^y  the  use  of  a  colpeurynter.  If  the  head  remains  high  long  after 
complete  dilatation,  it  may  be  advisable  to  anesthetize  the  woman,  change  the  posi- 
tion to  one  anterior,  impress  the  head  into  the  pelvis  by  combined  manipulation  or 
draw  it  down  "with  forceps,  and  then  leave  the  case  to  nature.  In  primiparse  this 
method  is  far  more  preferable  than  version,  which  almost  always  kills  the  babies  and 
always  lacerates  the  mother. 

After  the  head  has  engaged,  watchful  expectancy  is  still  practised,  because  the 
vast  majority  of  cases  terminate  in  anterior  rotation,  or  at  least  in  rotation  to  or 
beyond  the  transverse  diameter,  and  thus  become  easy  forceps  operations.  Change 
in  posture,  even  the  knee-chest,  may  be  tried,  but  most  of  the  time  the  woman 
should  lie  on  the  side  to  which  the  occiput  points.  Hodge's  manccuver  may  be 
helpful — upward  pressure  on  the  sinciput  during  pains.  This,  by  increasing  flexion, 
favors  rotation.  Tarnier  advised  direct  rotation  of  the  head  with  the  fingers  or 
half-hand,  operating  from  behind  the  ear,  at  the  same  time  pressing  the  forehead  to 
the  rear  from  the  outside.  Older  writers,  among  whom  Hodge  may  be  mentioned, 
recommended  the  vectis  for  these  cases.  Objections  to  all  these  manoeuvers  may 
be  urged  on  the  score  of  danger  of  infection  and  inefficiency.  In  multipara  they 
occasionally  succeed,  and  may  shorten  the  labor  somewhat.  At  all  events,  they 
should  not  be  persisted  in,  and  much  force  may  not  be  used,  but  if  an  indication 
arises  for  interference,  it  is  best  to  make  the  manual  correction  of  the  malposition 
under  anesthesia,  as  is  described  in  Chapter  LXX,  page  930.  Failing  the  last, 
recourse  is  to  be  had  to  forceps. 

Occipitosacral  positions  often  require  assistance.  If  the  head  is  descending  in 
flexion,  the  perineum  is  not  endangered  as  much  as  when  the  forehead  comes  do^\Ti. 
In  either  case  a  deep  episiotomy  is  indicated  unless  the  patient  is  a  multipara.  (See 
Chapter  on  Forceps.) 

Internal  Super-rotation. — In  roomy  pelves,  or  when  the  child  is  small,  anterior 
rotation  of  the  occi]iut  may  l)e  exaggerated,  the  small  fontanel  passing  beyond  the 
middle  line  to  the  opposite  side  of  the  pelvis.  An  O.L.A.  may,  in  the  course  of  labor, 
become  an  O.D.A.  The  accoucheur  will  be  surprised  to  find  the  l^ack  on  one  side 
and  the  occiput  on  the  other,  but  sometimes  the  back  rotates  too  and  the  attendant 
will  imagine  his  first  diagnosis  was  wrong.  Indeed,  occasionally  the  head  will  rotate 
through  the  hollow  of  the  sacrum  from  an  O.L.P.  to  an  O.D.P.,  and  the  back,  which 
at  first  was  on  the  left,  later  lies  on  the  right,  side.  In  internal  super-rotation  the 
head  in  the  course  of  delivery  may  turn  back  again,  or  may  escape  in  an  ol)lique

diameter  of  the  outlet,  the  back  pointing  to  the  side  opposite  that  of  the  occiput,  hut 
sometimes  the  trunk  follows  the  rotation  of  the  head,  and  may  escajH'  with  the  Ijack 
looking  directly  upward,  or  even  to  the  sitle  to  which  the  occiput  had  rotated.  A 
turl)inal  movement  is  thus  imparted  to  the  child. 

Again,  thcjugii  the  head  comes  out  in  the  normal  mechanism,  the  Bhoulders 
may  sup<'r-r(jtate,  the  hack  coming  out  on  the  side  opposite  that  t<j  which  the  occiput 
originally  jiointed.  A  knowledge  of  these  variations  of  the  mechanism  of  delivery 
is  necessary  for  the  proper  conduct  of  the  end  of  the  second  stage.  As  a  general 
rule  nature  needs  no  help.  \\'hen  the  delivery  of  the  trunk  is  too  slow,  the  woman 
should  he  asked  to  hear  d<nvn;  a  moderate  pressure  may  he  exerted  on  the  fundus, 
but  traction  on  the  child  is  made  only  when  absolutely  necessary.  In  doing  this 
the  accoucheur  should  aid  and  supplement  the  mechanism  evidently  intended  by 
nature.  For  example,  if,  after  delivery  of  the  head,  external  restitution  dot^  not 
occur,  but  the  siiouldcrsshow  a  tendency  to  turn  in  a  direction  ojiposite  to  that  which 
was  expected,  the  attendant  should  favor  the  movement,  because  if  he  sought  to 
impress  a  contrary  one,  the  child  would  stoj)  in  its  rotjition  ;unl  tin-  b;i<-k  would

come  out  transversely,  with  injury  to  the  perineum  or  fracture  of  the  child's  clavicle, 
or,  indeed,  the  delivery  of  the  body  would  be  arrest eil,  recjuiring  strong  traction  in 
order  to  free  it. 

Deflexion  Attitudes. — Often,  during  an  examination  early  in  lalK>r,  the  head  is 
found  lying  over  the  inlet  with  the  lai^c  fontanel  lower  than  the  small,  or  even  with 
the  root  of  the  nose  anil  the  eyes  palpable.  After  regular  uterine  at-tion  is  estal>- 
lished,  or  if  the  parturient  adopts  a  favorable  posture,  the  small  fontanel  will  sink 
and  labor  will  assume  a  normal  mechanism.  Should  the  cause  of  the  abnormal  atti- 
tude of  the  child  jiersist.  the  body  of  the  child  will  remain  in  the  wrong  posture,  the 
uterus  will  fix  the  trunk  and  a<lai)t  itself  ]M'rmanently  to  the  abnormal  conditions, 
a  pathologic  mechanism  resulting.  All  degret^s  of  deflexion  of  the  head  may  Ik* 
found,  but  it  would  be  useless  ami  confusing  to  descriU'  them  all.  Clinically,  four 
of  these  deflexion  attitudes  (leser\'e  mention  as  distinct  jiresentations,  having  a 
clearly  defined  course  and  mechanism.  Named  in  the  order  of  the  degree  of  de- 
flexion, they  are:  (1)  Minlian  vertex  presentation,  or  "military"  attitude;  (2)  fore- 
head presentation;  (3)  brow  presentation;  (4)  face  prest'ntation.  In  all  thes<'  the 
trunk  of  the  child  passes,  in  a  varying  degree,  from  its  natural  condition  of  flexion

or  C  shape  to  one  of  extension  or  S  shape,  face   presentation  representing  the 
greatest  change  (Figs.  506-509). 

Causation. — All  cases  of  deflexion  attitudes  cannot  be  explained  by  one  cause, 
anil  often  several  factors  combine  to  produce  the  abnormal  presentation.  In 
general,  primary  and  secondary  factore  may  be  distinguished,  i.  e.,  those  active 
during  pregnancy  and  those  showing  in  labor.  The  primary  factors  are  anything 
that  will  cause  a  straightening  of  the  child's  trunk,  as  tumors  of  the  fetus,  tumors  of 
the  uterus  pressing  in  the  fetal  back,  a  congenitally  long  uterus  which  cannot  adapt 
itself  well  to  a  curved  fetal  back,  obliquitj^  of  the  uterus,  tumors  of  the  neck  of  the

fetus,  as  goiter,  a  short,  deep-chested  child  which  does  not  allow  the  chin  to  flex 
fully,  and  the  spontaneous  nutatory  movements  of  the  child.  Should  the  pains 
come  on  when  the  infant  happens  to  have  his  head  extended,  the  lower  uterine 
segment  may  lock  the  child  in  this  position.  Baudelocque  called  attention  to  the 
wrong  direction  of  the  uterine  forces  when  the  uterus  was  oblique  to  the  inlet- — if 
the  back  falls  over  to  the  side  of  the  occiput,  the  chin  extends,  and  if,  now,  uterine 
action  commences,  the  fetal  axis  pressure  is  exerted  in  the  direction  of  the  chin, 
increasing  the  extension,  even  to  the  production  of  a  face  presentation.  Anen- 
cephali  usually  present  by  the  face — snout  labors  (Ahlfeld).  Congenital  dolicho- 
cephalus  (Hecker) — elongation  of  the  head — may  favor  face  presentation.     Poly-

hydramnion,  \iy  conferring  a  liij^li  ilcj^rce  of  inol)ility  on  the  fetus,  is  a  predisposing 
factor.  Secondary  causes  are:  (1)  Those  conditions  whicli  prevent  or  delay  en- 
gagement of  the  head,  as  contracted  jM-lvis,  large  head  (face  hahies  are  often  large), 
pendulous  belly,  tumors  occujjying  the  lower  uterine  segment,  as  the  placenta,  or 
narrowing  the  inlet — the  full  rectum,  full  bladder;  (2)  rupture  of  the  bag  of  waters 
when  the  head  happens  to  be  in  e.\t»'nsion;  (3)  occipitoposterior  positions;  (4)  a 
cause  of  deflexion  attitudes  not  generally  appreciated  is  weak  lal)or  pains.  With  a 
normal  pelvis  the  cervix  exerts  a  certain  influence  on  the  mechanism  of  labor.  Tlie 
head  presenting  to  it  with  the  broad  flat  vertex  will,  imder  strong  vis  a  tergo,  adapt 
itself  so  as  to  l)ring  the  longest  diameter  of  its  ovoid  into  a  position  parallel  with  the 
axis  of  the  poi^sage,  so  that  it  can  go  through  with  the  lea.st  fricticjn.  With  weak  i)ains 
the  head  will  not  apply  itself  to  the  cervix  and  thus  come  under  the  latter's  influence. 
Nearly  always  the  cause  of  deflexion  is  maternal,  and  operates  during  labor, 
but  the  author  would  emphasize  the  role  that  the  child  plays.  Xutatory  move- 
ments are  often  felt  during  vaginal  examination,  and  it  is  ea.sy  to  understand  that, 
should  lai)or  come  on  or  the  membranes  rupture  while  the  child  has  the  chin  ex-

tended  the  attitude  will  be  fi.xed,  antl  the  deflexion  may  become  exaggerated  as 
labor  progresses.  For  example,  in  occipitoposterior  presentation  a  slight  extension 
will  throw  the  forehead  over  the  inlet.  Should  the  patient  turn  on  the  side  to 
which  the  venter  of  the  fetus  points,  the  trunk  will  fall  over  to  that  si<le  and  the 
brow  will  sink  lower,  and  if  pains  come  on  strongly,  the  bregma  will  stem  on  the 
edge  of  the  inlet  and  a  full-face  presentation  result.  Often  early  in  lal)or  the  ex- 
amining finger  feels  the  brow  or  the  forehead  high  over  the  inlet,  but  by  profXTly 
placing  the  patient — that  side  to  which  the  occiput  jxtints — the  breech  will  fall 
into  the  flank,  the  occiput  will  sink,  and  flexion  result.  These  passing  deflexion 
attitudes  should  not  mislra<l  to  hasty  interference. 

Mechanism  of  Labor  in  Median  Vertex  Presentation. — Most  authors  do  not 
recognize  this  form  of  anomaly.  l)Ut  Hau(lcloc(iue,  \Clpeau,  and  Hodge  have  de- 
scribed it,  and  Hirst,  among  other  modern  writers,  mentions  it.  I  beli«'ve  it  is  a 
frequent  cause  of  dystocia.  When  the  deflexion  is  only  moderate,  the  child  pre- 
senting with  its  head  in  the  "military"  attitude,  labor  is  very  .similar  to  that  in 
occipitoposterior  posit icms.  As  the  point  of  din'ction,  or  denominator,  the  occiput 
is  still  employed,  although  sometimes  in  abnormal  mechanisms  the  forehead  de-

THE    PATHOLOGY    OF    LABOR 


scends  and  becomes  the  point  of  direction — a  fact  of  great  importance  in  the  forceps 
operation. 

Engagement  of  the  head  is  slow,  because  the  largest  plane,  the  occipitofrontal, 
is  presented  to  the  inlet.  Descent  continues  with  the  large  and  small  fontanels  on 
the  same  level, — that  is,  flexion  remains  absent, — and  with  the  sagittal  suture  in  the 
transverse,  until  the  median  vertex  reaches  the  pelvic  floor  (Fig.  511).  Now  four 
terminations  are  possible:  (1)  Flexion  occurs,  the  occiput  rotates  anteriorly  under 
the  pubis,  and  labor  terminates  normally;  (2)  delivery  takes  place  with  the  sagittal 
suture  in  the  transverse  diameter — requires  strong  pains,  large  pelvis,  small  child, 
the  perineum  being  much  endangered;  (3)  the  occiput  rotates  into  the  hollow  of 
the  sacrum,  the  forehead  turns  to  the  pubis,  and  the  mechanism  is  similar  to  occipito-

tion.  The  caput  succedaneum  is  on  one  parietal  bone,  close  to  the  posterior  third 
of  the  sagittal  suture  (Fig.  512). 

Clinical  Course. — Labor  is  longer  and  tedious.  The  pains  are  weak  and  in- 
frequent, because  the  presenting  part  does  not  press  firmly  against  the  cervix. 
Dilatation  is  slow,  and  the  cervix  must  be  opened  wider  to  allow  the  head,  presenting 
its  biggest  planes,  to  pass  through.  After  the  head  reaches  the  pelvic  floor  the  pains 
usually  become  augmented,  and  one  of  the  terminations  mentioned  occurs,  but  in 
all  cases  strong  pains  are  needed.  These  may  fail,  and  the  assistance  of  art  is  often 
required. 

Diagnosis. — Abdominally,  the  usual  points  for  determining  presentation  and 
position  are  to  be  sought,  and  the  examiner  will,  notice  that  the  trunk  of  the  child 
is  very  straight,  the  fundus  applied  to  the  ensiform,  the  heart-tones  near  the  median 
line,  and  heard  over  a  large  area— distant  in  O.L.T.,  louder  in  O.D.T.  The  shoulder 
is  in  the  median  line,  just  above  the  pubis.  Internally  (Fig.  513),  the  finger  dis- 
covers the  two  fontanels  on  the  same  level,  the  sagittal  suture  running  across  the 
pelvis.     Usually  the  head  is  synclitic,  but  anterior  asynclitism  has  been  observed,

especially  in  pendulous  abdomen  and  flat  pelves.  Naturally,  the  findings  change 
as  the  various  mechanisms  unfold. 

Trent  me  nl.^TWis  is  the  same  as  that  of  occipitoposterior  positions. 

Forehead  Presentations. — These  are  primary  or  secondary.  Primary  fore- 
head mechaiiisins  are  very  rare  because,  if  the  deflexion  has  proceech-d  thus  far,  the 
forces  of  labor  almost  always  complete  the  jjnjce.ss,  a  face  or  at  least  a  brow  presenta- 
tion resulting.  The  forehead  is  the  point  of  direction— it  takes  the  lead,  descent 
occurs,  usually  in  one  of  the  obliques,  until  the  presenting  part  roaches  the  pelvic 
floor.  Now  three  mechanisms  occur:  (1)  Under  strong  jxiins  and  late,  flexion  of 
the  head,  descent  of  the  occiput,  and  anterior  rotation  of  tlie  latter  under  the  pubis 
(rare);  (2)  anterior  rotation  of  the  forehead  under  the  pubis  while  the  occiput 
turns  behind,  the  glabella  stemming  under  the  arch,  the  occiput  coming  over  the 
perineum,  in  all  respects  similar  to  the  second  mechanism  of  occipitoposterior 
positions;    (3)  cessation  of  jirogress  with  the  forehead  on  tiie  perineum. 

Secondary  forehead  presentations  urr  th<'  result  of  deflexion  of  the  head  and 
descent  of  the  forehead  in  occipitoposterior  positions,  to  which  the  reader  is  re- 
ferred for  a  description  of  the  mechanism  and  for  diagnosis  and  treatment. 

Primary  forehead  presentations  closely  resemble  the  brow,  but  an  internal 
examination  will  show  the  large  fontanel 
in  the  line  of  direction  (Fig.  514).  The 
configuration  of  the  head  is  shown  in  Fig. 
503,  and  the  caput  succedaneum  over  the 
bregma  exaggerates  the  tower-like  raising 
of  the  vault  of  the  cranium  In  the  treat- 
ment of  primary  fon^head  presentations  it 
must  be  remembered  that  often,  in  the  be- 
ginning of  labor,  the  forehead  is  to  be  felt 
over  the  inlet,  but  when  the  head  enters, 
flexion  occurs  and  the  occiput  comes 
down,  rotating  anteriorly.  By  keeping 
the  patient  on  the  sitle  on  which  the  occi- 
put lies,  flexion  and  descent  of  the  head 
are  favored.  King  advi-ses  the  squatting 
posture,  claiming  that  the  i)ressure  of  the

affects  the  position  of  the  child.     If  it  is 

desired  to  exert  i)ressure  on  the  back  of  the  child,  the  woman  kneels  on  one  knee,  the 
other  foot  resting  flat,  and  the  corresponding  thigh  being  i>res.sed  firmly  against 
the  abdomen,  where  the  back  lies  (Fig.  654).  Should  the  foreheail  not  change  its 
location,  labor  does  not  progress,  and  the  case  is  to  be  treated  as  a  brow  presenta- 
tion, with  which,  indeed,  it  is  often  confused  in  practice. 

Brow  Presentation. — Transitory-  j)re.sentation  of  the  brow  in  the  beginning  of 
labor  is  occasionally  olwerveil,  and  as  the  head  engages  in  the  jx'lvis  descent  of 
the  occiput  occurs,  and  a  more  normal  mechanism  results.  More  frequently  the 
deflexion  is  completed,  and  a  face  presentation  is  protluced.  Brow  presentation  is 
distinctly  inithologic.  and  if  the  child  is  normal  or  above  normal  in  size.  l>ecomes 
very  formidal)le.  Small  or  macerated  fetuses  may  pa.ss  through  the  ix'lvis  sj)on- 
taneously,  tliough  labor  is  usually  difficult  and  much  i)rolonge«l. 

The  frequency  of  brow  jiresentation  is  variously  given— ix-rhajis  once  in  3000 
cases  is  as  near  accurate  as  is  possible  to  get.  In  the  Moscow  maternity  brow  pres- 
entation occurred  101  times  in  130.70S  labors.  Its  causes  come  under  the  general 
etiolog>'  of  deflexion  attitudes,  but  the  fre(iuency  of  contracted  |K'lvis  must  l>e 
emphasizeil  (in  4.")  per  cent,  of  the  abuve-mentione(l  ca.ses).  and  this  may  ex])lain.

shape  of  the  back  is  more  marked  than  in  forehead,  but  less  than  in  face  presen- 
tation, Avhich,  however,  it  closely  approaches.

arc  of  rotation.     Descent  of  the  head  is  slow,  and  starts  only  after  complete  dilata-

tion,  with  the  rupture  oi  the  membranes.  Since  the  preparation  of  the  cervix  is 
poor,  delay  in  the  first  stage  is  the  rule.  Unless  the  attitude  is  to  change  to  either 
a  face  or  an  occiput  presentation,  the  brow  descends  in  the  middle  of  the  jx^vis,  the 
head  holding  itself  midway  between  flexion  antl  extension.  During  the  descent 
the  frontal  suture  usually  takes  the  transverse  diameter  and  is  synclitic  (Fig.  516), 
unless  the  pelvis  is  flat.  When  the  i)elvic  Hoor  is  reached,  the  bnjw  njtates  to  the 
front,  and  the  occiput  to  the  hollow  of  the  sacrum.  The  factors  producing  this  ro- 
tati(in  are  the  same  as  those  operative  in  normal  cases — the  pelvic  floor,  the  guidance 
of  the  converging  rami  pubis,  and  the  acccMnuKjdation  of  the  fetal  cylinder,  which 
is  easily  flexible  only  in  certain  directions — to  the  bent  birth-canal  (Sellheim). 
In  the  brow  attitude  the  fetal  cylinder  can  bend  best  in  its  sagittal  diameter.  The 
sagittal  diameter,  therefore,  is  brought  to  correspond  with  the  sagittal  diameter  of 
the  pelvis.  The  brow,  therefore,  comes  down  and  turns  to  the  front  until  the  face 
rests  behind  the  pubis.  In  the  rima  vulva*  tlie  brow,  covered  by  a  large  caput  suc- 
cedaiieum,  first  ai)pears;  then,  under  very  strong  expulsive  pains,  by  a  movement 
of  flexion,  the  large  fontanel,  the  vertex, 
and  the  occiput  successively  pa.ss  over 
the  ])erineum,the  nape  of  the  neck  com- 
ing to  rest  upon  it,  after  which  the  eyes, 
nose,  mouth,  and  chin  come  from  be- 
hind the  pubis  with  one  movement. 
Sometimes  the  brow  is  delivered  up  to 
the  mouth  before  the  occiput  escapes,

and.  rarely,  the  head  may  escape  with  tlie  frontal  suture  in  the  transverse  diameter  of 
the  outlet;  that  is,  internal  anterior  rotation  has  not  occurred.  It  will  Ix'  seen  that 
the  accomplishment  of  such  a  mechanism  must  be  slower,  hartler.  and  more  dan- 
gerous to  mother  and  child  than  any  other.  The  perineum  is  almost  always  lacer- 
ated, and  often  tears  high  up  into  the  rectum,  becau.»<e  the  largei^t  diameters  are 
offered  to  the  outlet.  Clinically,  it  is  very  difficult,  at  this  stage,  to  tlistinguish  a 
brow  presentation  from  terminal  occij)itosacral  and  forehead  mechanisms  If  the 
chilli  is  large,  operation  is  almost  ahva>'s  necessarj-  to  eflfect  delivery. 

Diagnosis. — Abdominally,  the  findings  are  the  same  a.s  in  face  cases  (q.  v.). 
Internally  (Fig.517),the  l)regma  is  the  lowest  ixiint,occui>ies  the  center  of  the  jx^lvis, 
th(>  large  fontanel  being  paljiable  on  one  side,  the  r(M)t  of  the  nose  and  orbital  ridg(^ 
on  the  other.  The  no.se,  mouth,  and  chin  are  high  up.  oiit  t)f  reach  unless  the  pa- 
tient is  anesthetized,  to  allow  deep  insertion  of  the  four  fingers.  The  frontal  suture 
runs  in  the  transverse  diameter  or  a  little  obliquely,  and  the  amount  of  the  facial 


592  THE    PATHOLOGY    OF   LABOR 

line  which  is  palpable  determines  the  degree  of  deflexion.  In  true  Ijrow  presenta- 
tion the  nose  is  not  to  be  felt,  the  orbital  ridges  being  on  a  level  with  the  posterior 
border  of  the  large  fontanel,  the  two  demarcating  the  girdle  of  resistance. 

]\Iolding  is  characteristic  (Fig.  518),  the  head  having  acquired  a  three-cornered 
outline.  The  face  is  flattened  out,  the  distance  from  chin  to  top  of  forehead  very 
great,  and  this  is  exaggerated  temporarily  by  the  large  caput  succedaneum. 

The  treatment  of  brow  presentation  must  be  active  unless  it  seems  certain  that 
spontaneous  correction  will  occur.  To  favor  flexion  the  patient  is  put  on  the  side 
to  w'hich  the  occiput  points,  but  if  this  does  not  speedily  bring  about  the  desired 
result,  it  is  best  to  correct  the  presentation  under  ether  before  the  head  engages  and 
molding  commences.  Before  the  rupture  of  the  bag  of  waters,  nothing  but  the 
use  of  posture  need  be  done.  When  the  cerx-ix  is  fully  dilated,  the  membranes  may 
be  punctured,  the  head  flexed  and  led  into  the  pelvis  either  by  the  two  hands  or  the 
forceps,  after  w^hich  the  case  is  left  to  nature.  (See  Operative  Obstetrics.)  Should 
it  be  impossible  to  change  the  brow  into  an  occipital  presentation,  which  is  most 
desirable,  the  attempt  may  be  made  to  obtain  a  full  face  presentation,  and,  failing 
this,  version  is  to  be  performed. 

After  the  engagement  of  the  head  in  brow  presentation  all  manceuvers  are 
rendered  more  difficult  and  dangerous.  It  is  astonishing,  however,  what  may  be 
accomplished  under  deep  anesthesia.  When  the  abdomen  and  uterus  are  fully 
relaxed,  it  is  often  easy  to  push  the  head  out  of  the  pelvis,  flex  or  extend  it,  and 
draw  it  back  in  proper  attitude  and  position.  Version  at  this  stage  is  very  risky, 
because  the  lower  uterine  segment  is  usually  much  stretched  in  brow  cases,  and, 
further,  version  is  always  to  be  avoided  in  primiparse  if  possible.  Should  version 
be  out  of  the  question  and  manual  correction  fail,  the  attendant  has  two  alternatives 
— a  cutting  operation,  as  abdominal  delivery  or  hebosteotomy,  and  expectancy,  in 
the  hope  that  strong  pains  will  so  mold  the  head  to  the  pelvis  that  it  will  finally  go 
through  or  can  be  delivered  by  forceps.  If  the  child  is  large  or  the  pelvis  small,  the 
latter  process  is  not  to  be  expected,  and  if  the  mother  and  baby  are  in  perfect  condi- 
tion, the  accoucheur  should  seriously'  consider  the  other  procedures  as  primary 
operations. 

WTiat  has  been  said  acquires  greater  force  in  labors  with  the  brow  in  posterior 
position.  Here  spontaneous  delivery  is  impossible  unless  the  infant  is  very  small, 
which  is  also  true  of  face  presentation.  Symphj'siotomy  has  been  performed  by 
H.  F.  Le-\\ds  and  ^Montgomery  for  the  relief  of  dystocia  due  to  brow  presentation. 
Since  some  degree  of  pelvic  contraction  is  frequent  in  such  cases,  symphysiotomy 
or  even  cesarean  section  must  always  be  taken  into  consideration.  Should  nature's 
efforts  suffice  to  bring  the  head  well  down  onto  the  perineum,  the  additional  power 
required  for  delivery  may  be  applied  by  the  forceps.  (See  Operative  Obstetrics.) 
Forceps  operations  in  brow  cases  are  nearly  always  very  difficult,  and,  should  the 
hazard  be  too  great,  craniotomy  is  to  be  performed. 

Face  Presentation. — When  the  deflexion  is  carried  to  its  highest  degree,  the 
full  face  comes  to  lie  in  the  line  of  direction,  or  is  bounded  by  the  girdle  of  resistance 
and  is  felt  by  the  examining  finger.  This  is  face  presentation,  and  it  occurs,  in 
round  numbers,  about  once  in  200  cases.  In  face  presentation  the  chin  is  the  point 
of  direction  or  denominator,  and  the  six  positions  of  presentation  may,  in  individual 
cases,  be  distinguished.  Mentodextra  transversa  is  the  most  frequent,  mentolseva 
anterior  the  next,  mentodextra  posterior,  clextra  anterior,  l«va  transversa,  and  laeva 
posterior  in  order.  The  various  statistics  show  differing  frequencies  of  the  several 
positions,  but,  in  general,  face  positions  occur  in  the  order  of  the  frequency  of  the 
occipital  positions  from  which  they  were  developed;  for  example,  since  O.L.T.  is 
the  usual  position  which  the  head  takes  on  entering  the  pelvis,  the  deflexion  of  the 
chin  will  bring  the  face  down  in  INI.D.T. 

As  a  rule,  face  presentations  are  fully  developed  only  after  labor  has  been  in

ered early  in  the  firet  stage,  but  in  two  eases  I  distinctly  felt  the  full  face  lying  over 
the  inlet  in  the  last  month  of  pregnancy,  an  observati(m  which  was  alscj  made  by 
LaChapelle,  Naegele,  Fieux,  and  others. 

Mechanism. — Figs.  519  and  520  show  the  attitude  or  posture  of  the  fetus  in 
two  of  the  common  positions.  The  head  is  (•(jmpletely  extended  on  the  back,  the 
forehead  is  flattened,  and  the  occiput  long  drawn  out.  The  neck  is  stretched;  some- 
times there  are  cracks  in  the  skin  from  overstretching.  The  chest  is  protruded  and 
is  convex.     The  back  is  sharply  incurved  to  receive  the  occiput,  while  the  breech

is  turned  to  the  back.     The  fetus  is  lengthened,  while  its  axis  tak(^  the  shape  of  the 
letter  S. 

At  the  l)eginning  of  labor  the  head  lies  high,  with  nuKlerate  anterior  :isynclitism, 
the  anterior  malar  bone  anil  orbit  l)eing  nearer  the  middle  line  and  lower.  Iiustead 
of  flexion,  as  descent  begins,  we  observe  an  exaggeration  of  the  e,xtensi»)n.  the  chin 
becomes  more  accessil)le,  and  the  brow  recedes  a  little.  Descent  occurs,  with  the 
facial  line  usually  in  the  transvers<>  diameter  of  the  iK'lvis.  In  M.L.A.  the  chin 
points  to  the  obturator  foramen,  that  is,  lies  in  the  left  anterior  ({uadrant  of  the 
pelvis;  in  M.D.P.  the  chin  points  to  the  right  posterior  (iua«irant.  and  the  facial

THE    PATHOLOGY    OF    LABOR 


opposed  to  that  of  occipital  attitudes.  In  occipital  presentations  the  fetal  cylinder 
can  accommodate  itself  best  to  the  angular  birth-canal  by  breaking  at  the  fetal  neck 
and  the  occiput  bending  backward — that  is,  extension  occurring.  In  face  presenta- 
tions the  same  bending  occurs,  but  reversed,  and  the  chin  flexes.  In  order,  there- 
fore, for  the  fetal  cylinder  to  accommodate  itself  easiest  to  the  birth-canal,  it 
rotates  so  as  to  bring  the  chin  forward  under  the  puljis  (Fig.  521).  Anterior  rota- 
tion must  have  begun  before  the  face  reaches  the  second  parallel  plane  of  Hodge, 
because  the  head,  if  normal  in  size,  cannot  enter  the  pelvis  with  the  chin  behind. 
This  would  bring  the  occiput  and  the  upper  chest  and  shoulder  region  into  the  inlet 
at  the  same  time,  and,  under  normal  conditions,  progress  in  this  fashion  would  be 


Fig.  .520. — Face  Presentation.     ^LD.P. 


impossible.  Under  the  exceptional  combination  of  large  pelvis,  small  child,  and 
strong  pains,  labor  may  progress  and  terminate  spontaneously  with  the  chin  pos- 
terior. Usually  in  those  cases  of  spontaneous  labors  with  the  chin  behind,  the  head 
entered  the  pelvis  with  the  chin  transverse  or  anterior,  and,  after  engagement,  the 
chin  rotated  to  the  hollow  of  the  sacrum,  the  shoulders  entering  in  one  of  the 
obliques.  Further,  mentosacral  positions  terminating  happily  for  mother  and  child 
are  so  exceedingly  rare  that,  for  practical  purposes,  it  is  best  to  consider  them  as 
absolutely  pathologic  and  as  always  requiring  interference  from  art. 

Anterior  rotation  being  completed,  or  nearly  so,  the  chin  comes  to  lie  behind 
the  pubis  near  to  the  urethra,  the  forehead  is  behind  the  fourchet,  and  the  occiput 
occupies  the  hollow  of  the  sacrum.     The  fourth  movement  is  not  extension  as  in

Abnormal  mechanisms  can  occur  in  the  rotation.     (1)  Deep  arrest  of  rotation, 

the  face  coming  deeply  into  the  pelvis,  and 
even  pressing  firmly  on  the  perineum,  but 
not  turning  to  the  front,  the  facial  line 
resting  in  the  transverse  diameter.  Under 
favoralile  conditions — large  pelvis,  small 
child,  relaxed  pelvic  floor  (multipara),  and 
strong  pains — the  head  may  escape  in  this 
position,  the  flexion  of  the  chin  taking 
place  over  one  descending  ramus  pubis. 
Otherwise,  unless  aid  is  rendered,  labor 
ceases,  and  both  mother  and  child  will  die. 
(2)  The  second  anomaly  is  where  the  chin 
remains  at  the  sacro-iliac  joint,  or  even 
rotates  into  the  hollow  of  the  sacrum. 
These  are  called  persistent  chin  posterior 
positions,  and  are  very  formidable 
(Fig.  525).  It  has  already  been  shown 
that  the  head  cannot  enter  the  pelvis  with 
the  chin  liehind,  and  it  is  easy  to  see  how 
difficult  labor  will  be  should,  after  engage- 
ment, the  mentum  turn  back  toward  the 
sacrum.  Then  the  broad  occiput  and  the 
chest  must  pass  the  inlet  together,  which 
is  possible  only  under  most  favorable  conditions.  Rarely,  nature  terminates  these 
cases,  first,  by  anterior  rotation  even  as  late  as  this;  second,  by  delivering  the 
head  as  a  brow  presentation 
with  posterior  rotation,  the  oc- 
ciput coming  dow^i  from  behind 
the  pubis,  and,  third,  the  face  is 
forced  down  and  out  in  the  ab- 
normal position,  without  regard 
to  the  soft  parts,  which  are  torn 
most  extensively  in  all  direc- 
tions. Should  none  of  these  oc- 
cur and  art  be  absent,  the  baby 
dies  from  asphyxia  and  the 
mother  from  ruptured  uterus 
or  exhaustion. 

Clinical  Course.— Labor  in 
face  presentation  is  usually 
longer — by  three  or  four  hours 
in  primiparse  and  one  or  two 
hours  in  multiparse.  Since  the 
soft  face  does  not  press  so  hard 
nor  so  evenl}'  as  the  occiput  on 
the  cervix,  the  pains  are  weaker, 
especially  in  the  first  stage. 
Dilatation  of  the  cervix  is,  there- 
fore, delayed,  and  this  is  often 
enhanced  fby  the  early  rupture 
of  the  bag  of  waters,  which  is

vix,  allowing  the  full  force  of  the  general  intra-uterine  pressure  to  act  on  the  mem- 
branes. The  cause  of  the  face  presentation,  for  example,  contracted  p«'lvis,  tumors, 
placenta  pra?via,  may  also  be  responsible  for  other  anomalies.  Engagement  of  the 
head  is  slow,  but  anterior  rotation  comes  on  suddenly  and  is  usually  quickly  accom- 
plished, as  is  also  the  delivery.  Primipara?  less  often  have  face  presentations,  and 
naturally  in  them  the  mechanism  isshjwer  and  more  arduous.  (Jwing  to  the  extreme 
lengthening  of  the  fetal  ovoid  the  lower  uterine  segment  is  put  on  the  stretch,  which 
must  Ije  remembered  during  the  treatment. 

Diagnosis. — Abdominally,  the  ovoid  is  longitudinal  and  very  long,  the  flanks 
being  quite  flat.  The  shape  of  the  uterus  alone  may  sometinjes  sufhce  to  make  a 
diagnosis.  Over  the  inlet  the  head  is  felt,  and  in  the  fundus  the  breech  with  small 
parts,  the  latter  unusually  easily  outlined.     It  is  often  difficult  to  map  out  the

consistence^  and  not  showing  the  triangular  area  pictured  in  Fig.  802.  This  is  the 
chest  of  the  infant,  and  in  one  case  I  coukl  feel  the  child's  heart  beat,  which  has 
also  been  found  by  others.     The  back  may  occasionally  Ix*  felt  by  deep  pressure. 

Above  the  inlet,  to  one  side,  is  felt  a  hard,  round  prominence,  the  occiput,  and 
this  is  separated  from  the  back  by  a  deep  furrow.  On  the  other  side  the  inlet  is 
empty,  but  if  the  patient  is  docile  and  the  abdominal  wall  relaxed,  with  de<'p 
pressure  the  fingers  may  come  uiK)n  the  horseshoe-shajKHl  jaw.  Clreat  imjiortance 
is  to  be  attached  to  the  finding  of  the  feet,  the  heart-tones,  and  the  chest  all  on 
the  same  side.  If  on  the  other  side,  over  the  inlet,  a  large,  hard  jmmiinence  is 
felt  with  a  sharp  groove  above  it,  the  diagnosis  of  face,  or  at  least  l»n>w.  prt^entation 
is  assured.     The  heart-tones  are  unusually  loud.

the  anterior  orbit,  if  not  the  root  of  the  nose.  As  soon  as  the  bag  of  waters 
ruptures  there  is  usually  no  difficulty  in  recognizing  the  eyes,  nose,  mouth,  and  jaw. 
Only  late  in  labor,  when  the  caput  succedaneum  has  disfigured  the  parts,  does  the 
face  feel  like  the  breech.    An  irregular  surface,  one  with  prominences  and  depressions,

present.  The  facial  line  lies  in  the  transverse  or  the  ol)li(iue  diameter  (Figs.  52(3

If  the  chiltl  is  alive,  it  may  suck  the

tliagnosis  is  the  determination  of  the 
degree  of  engagement.  The  head  is 
engaged  only  when  the  hiparietal 
diameter  has  passed  the  inlet.  In 
occipital  presentations  the  parietal 
bf)sses  have  just  sunk  below  the 
plane  of  the  inlet  when  the  lowest 
part  of  the  head,  the  vertex,  comes 
to  lie  in  a  line  rlrawn  from  one  ischi- 
atic  spine  to  the  other.  Inface  pres- 
entation, however,  when  the  brow 
or  the  root  of  the  nose,  that  is.  tlie 
lowest  portion  of  the  presenting 
part,  comes  to  lie  in  this  line,  the 
parietal  bos.ses  are  still  several  centi- 
meters al>ove  the  plane  of  the  inlet 
(Figs,  o'2S  and  .Vi'.M.  Only  when 
the  face  is  deep  down  on  the  pelvic 
floor  may  we  say  that  the  head  is 
engaged.

may  thus  be  caused.     Similar  precautions  are  advisable  with  the  use  of  antiseptic 
solutions. 

Plastic  Changes.- — If  the  lalwr  has  been  prolonged  after  rupture  of  the  mem- 
branes, the  face  is  horribly  disfigured  (Figs.  530  and  531).  Over  the  anterior  cheek 
and  eye  the  caput  is  always  found,  and  the  whole  face  is  involved,  the  eyes  bulge  out, 
the  lids  are  swollen,  a  mucoserous  discharge  escaping  from  them;  the  mouth  is  held 
open  by  the  tumid  lips,  the  tongue  sometimes  protrudes,  and  the  child  may  not  be 
able  to  nurse  for  several  days.  Minute  hemorrhages  under  conjunctiva  and  skin, 
sometimes  with  bullae,  intense  venous  congestion,  the  tumefaction  of  the  thyroid, 

and  the  cracks  in  the  skin  of 
the  neck  already  mentioned, 
give  the  child  a  most  dis- 
couraging appearance.  The 
shape  of  the  head  is  extremely 
dolichocephalic,  the  occiput 
being  long  drawn  out,  and 
there  may  even  be  a  saddle- 
shaped  depression  near  the 
large  fontanel.  The  child  lies 
in  its  crib  on  the  side,  with 
the  head  extended,  the  back 
straight,  and  may  keep  this  at- 
titude for  at  least  two  weeks. 
The  mother  may  be  reassured 
that  the  child's  features  will 
soon  regain  their  proper  ap- 
pearance. 

Prognosis  of  Face  and 
Brow  Presentations. — Without 
question  both  face  and  brow 
presentations  must  be  con- 
sidered pathologic.  The  mor- 
tality is  higher  in  both  because 
of  the  longer  labor,  the  greater 
danger  of  infection,  the  fre- 
quently necessary  operative 
interventions,  and  also  those 
unnecessarily  undertaken. 
While  the  majority  of  face 
cases  will  terminate  spontan- 
eously or  with  a  little  help 
from  art,  brow  presentation  is 
always  dangerous. 

For  the  child  the  mor- 
tality is  also  higher,  which  is  due  to — (1)  Prolonged  labor  and  cerebral  compression; 
(2)  compression  of  the  neck  against  the  pubis,  interfering  with  the  return  circulation 
from  the  head;  (3)  compression  of  the  trachea  and  larynx  against  the  pubis,  with 
suffocation  or  even  fracture;  (4)  injury  from  forceps  or  other  operation,  done  to  effect 
delivery.  Fully  four  times  as  many  children  die  from  face  presentation  as  in  occi- 
pital, and  fully  ten  times  as  many  in  Ijrow.  It  would  l)e  interesting  to  follow  up 
these  children  to  sec  if  the  extreme  molding  which  the  brain  suffered  affects  their 
mentality  in  any  way  in  later  life. 

Treatment. — Not    all    face    presentations    require    special    treatment.     The 
majority  terminate  spontaneously  and  happily  for  the  mother  and  babe,  without

the  assistanco  of  art.  Moschion  (a.  d.  100)  rocommfndcHl  that  all  such  presenta- 
tions he  changed  to  oeeipital;  Maurieeau  (1003)  and  de  la  M(jtte  (1721)  taught  the 
same.  Paul  Portal  (10>^5j  and  Deleurye  (1770j  took  the  opposite  side,  and  left 
them  to  nature.  Baudelocque  (a.  d.  1810)  advised  immediate  interference,  a 
teaching  which  is  still  felt,  in  spite  of  the  efforts  of  modern  obstetricians  to  dispel 
it.  Perhaps  the  fact  that  Hodge,  and  more  recently  Schatz,  reconunen(le<l  it,  dcjes 
nuich  to  exj)lain  the  present  freciuency  of  ojM'rative  measures  in  face  cases.  In 
1789  Zeller,  from  40  ca.ses,  and  in  17*J1  Boer,  in  \'ienna,  from  an  exix'rience  of  80 
cases,  showed  that  these  presentations  may  safely  be  left  to  nature,  79  of  Bwr's  80 
ca.ses  having  terminated  sj)ontaneously  with  only  4  fetal  deaths.  .laggard,  of 
Chicago  (died,  189()),  declared  in  the  strongest  terms  that  watchful  e.\p<*ctancy 
should  be  the  treatment  of  face  presentation.  No  one  nowadays  claims  that  it  is 
good  i)ractice  to  correct  every  face  presentation,  but  when  the  ca.ses  are  carefully 
differentiated,  many  will  be  found  where  the  interests  of  mother  and  child  are  l^est 
served  by  early  interference. 

Before  EngmjcntetU. — If  discovered  during  pregnancy  or  early  in  labor,  it  may 
be  possible  to  alter  the  attitude  of  the  child  by  Schatz's  method  of  abdominal 
manipulation.  During  labor  all  measures  which  preserve  th(>  l)ag  of  waters  are 
to  be  employed,  for  example,  the  side  position,  abstention  from  bearing-tlown 
efforts  by  the  i)atient,  and  care  during  examinations  l)y  the  accoucheur.  It  may 
be  very  advisal)le  to  put  a  colpeurynter  in  the  vagina,  filling  it  moderately.  If  the 
head  is  found  in  transition  from  vertex  to  face,  the  woman  should  lie  on  the  side 
to  which  the  occiput  points;  if  the  face  presentation  is  fully  formed,  she  .'should 
lie  on  that  side  which  will  favor  descent  and  anterior  rotation  of  the  chin,  that  is, 
the  side  to  which  the  chin  points.  As  a  rule,  in  the  absence  of  sjx'cial  indications, 
watchful  expectancy  is  the  treatment  to  i)e  pursued,  and  the  general  practitioner 
will  do  best  for  his  patient  if  he  gives  her  plenty  of  time  to  force  the  head  well  down 
into  the  pelvis  and  onto  the  perineum.  Then  he  may  wait  as  long  as  six  hours  for 
internal  anterior  rotation,  and  almost  always  his  ])atience  will  be  rewardetl  by  either 
a  sjiontaneous  delivery  or  sufficient  descent  and  anterior  rotation  that  the  forceps 
may  be  easily  and  safely  applied. 

If  the  position  is  one  with  the  chin  in  the  transverse  diameter,  or,  better  still, 
in  the  anterior  quadrants  of  the  pelvis,  this  is  the  invariable  treatment,  in  the 
absence  of  other  indication,  but  if  the  chin  is  pt)sterior  to  the  transverse  diameter 
of  the  pelvis,  a  more  active  conduct  may  be  advisable,  in  the  interests  of  the  child 
and  in  the  hope  of  reducing  the  length  of  the  labor  and  its  attendant  distress  and 
dangers.  If  the  head  remains  high  with  the  chin  posterior,  in  spite  of  good  pains, 
the  malj)resentation  may  be  changed  manually  to  one  of  the  occiput,  or  potlalic 
version  may  be  j)erformed.  There  is  no  unanimity  of  oi)inion  among  the  authori- 
ties regarding  the  selection  of  the.se  procedures.  Baudeloctiue,  Schatz,  Thorn, 
and  Hodge  i)refer  the  manual  correction,  as  do  most  motlern  writers.  Bumm 
prefers  version.  The  writer  has  had  almost  uniform  success  with  the  conversion 
of  face  presentation  to  occipital,  the  only  ca.ses  m  which  his  efforts  failed  U'lng 
those  in  which  labor  had  j)rogres.sed  too  far, extreme  molding  of  the  heatl  had  taken 
place,  and  the  uterus  had  become  strictured  around  the  chiUl's  neck.  Chin  i)os- 
terior  positions  are  particularly  favorably  altered  by  conversion  into  occiput  pres- 
entations, because  an  anterior  occiput  is  obtained,  for  example,  M.D.P.  l)ocomes 
anO.L.A.,  and  M.L.P.  an  O.D.A.  (For  the  methods  of  manual  corn-ction  sec  Chap- 
ter LXX.)  Should  it  l)e  impossible  to  correct  the  j)resentati(»n.  pudalic  version  may 
be  done,  and,  failing  in  this,  craniotomy  wouKl  be  neces.sary. 

After  Engagement. — When  the  head  is  engaged  in  the  j^elvis  with  the  chin  in 
the  transverse  diameter  or  even  anterior  to  it,  given  a  strict  indication  for  deliver>', 
forcei)s  is  the  operati(»n  t)f  choice.  Before  applying  the  instrument  an  attemj)t  is 
to  be  made  to  complete  the  rotation  of  the  chin  to  the  front  by  manipulation  with 


602  THE    PATHOLOGY    OF    LABOR 

the  fingers  or  half  hand.  A  purchase  is  obtained  on  the  posterior  malar  and 
frontal  bones,  and,  during  the  pains,  the  fingers  make  gentle  traction  ui)\vard  and 
forward,  trying  to  bring  the  chin  under  the  pubis,  aiding  the  maneuver  by  pressure 
on  the  occiput  from  the  outside  over  Poupart's  hgament.  Occasionally  a  little 
pressure  on  the  chin  to  exaggerate  extension  and  slight  traction  forward  will  help 
rotation.  If  rotation  can  be  thus  completed,  nature  may  terminate  the  case,  or, 
at  least,  the  forceps  operation  becomes  at  once  easier,  simpler,  and  safer. 

Should  the  chin  lie  behind  the  transverse  diameter,  or  ha\e  even  turned  toward 
the  sacrum,  the  family  is  to  be  advised  that,  with  the  usual  methods  of  delivery,  a 
dead  child  is  almost  a  certainty,  and  if  the  mother  and  child  are  in  prime  condition, 
the  question  of  cesarean  section  is  to  be  considered.  When  the  conditions  are  not 
ideal  for  an  abdominal  delivery,  the  accoucheur  should  try  to  change  the  chin 
posterior  to  an  occiput  anterior,  even  though  the  head  is  engaged.  Under  deep 
anesthesia  so  much  relaxation  of  the  uterus  occurs  that  a  surprising  degree  of  mobil- 
it}^  is  conferred  on  the  fetus.  It  is  then  possible,  and  if  it  is  done  gently  it  is  safe, 
to  push  the  head  up  and  out  of  the  pelvis  sufficiently  far  to  enable  the  author's 
method  of  manual  conversion  to  be  practised.  Naturally,  the  operation  requires 
the  greatest  circumspection,  but  the  end  will  justify  the  risk,  and  the  latter  is  very 
little  in  competent  hands.  If  conversion  fails  or  appears  too  hazardous,  manual 
rotation  of  the  chin  through  an  arc  of  three-fourths  of  the  half-circle  is  to  be  at- 
tempted. Unless  the  chin  can  1  )e  brought  into  the  anterior  half  of  the  pelvis,  forceps 
are  a  most  dangerous  and  destructive  instrument,  being  at  the  same  time  inefficient. 
Craniotomy  is  a  more  humane  operation,  and  has  hardly  a  higher  fetal  mortality 
than  the  forceps  used  in  such  instances.  Hodge  lauds  the  use  of  the  vectis  in  these 
cases,  but  modern  accoucheurs  hardly  know^  the  instrument.  In  the  treatment  of 
face  presentation  the  forceps  are  to  be  employed  only  when  absolutely  unavoidable. 
Before  doing  a  craniotomy  on  a  living  child  with  the  chin  posterior  a  gentle  attempt 
with  the  forceps  is  justifiable,  but  it  must  stop  short  of  maternal  injury.  For  these 
impacted  cases  pubiotomy  has  been  recommended.  In  all  face  deliveries,  spon- 
taneous and  operative,  the  fact  must  be  remembered  that  the  diameters  and  circum- 
ferences presented  to  the  pelvic  floor  outlet  are  not  so  favorable  as  in  occipital  de- 
liveries, and  that  the  pelvic  floor  is  pushed  further  dowTiward  and  torn  from  its  bony 
attachments.  Deep  episiotomy,  sometimes  going  through  the  pillar  of  the  levator 
ani,  is  almost  always  needed,  and  is  to  be  strongly  recommended.  After  -^  he  conver- 
sion into  an  occipital  presentation,  unless  the*"^  is  an  urgent  indication  fur  delivery, 
the  case  should  be  left  to  nature.  A  spontar  ■  deliver}^  may  now  occur— at  all 
events  the  head  will  be  molded  by  a  few  hoi,  or  into  a  favorable  shape,  and 

brought  low  into  the  pelvis,  sometimes  even  om  .  perineum,  making  the  eventual 
forceps  delivery  easy  and  safe. 

Every  face  and  brow  case  demands  a  comprehensive  diagnosis  of  all  adjuvant 
conditions  which  may  govern  the  methods  of  treatment.  As  such  may  be  men- 
tioned contracted  pelvis,  placenta  prsevia,  tumors,  eclampsia,  etc. 

It  is  advisable  to  observe  the  children  carefully  for  several  days,  since  edema 
of  the  glottis  may  occur.  Fracture  of  the  larynx  has  resulted  from  too  forcible 
pressure  of  the  trachea  against  the  pubis,  a  point  worth  remembering  while  con- 
ducting the  delivery.  The  scratch-marks  on  the  face  require  antiseptic  treatment. 
The  tumefaction  of  the  eyelids  will  subside  quickly  under  a  warm  boric  solution 
dressing.

BREECH  PRESENTATION 

In  about  3  per  cent,  of  cases  the  child  presents  itself  for  delivery  with  the 
breech  as  the  advancing  portion  of  its  IxmIv.  Most  autiujrs  consider  hreech  pn-s-

and  the  maternal  morbidity,  from  lacerations  and  sepsis,  decidedly  greater,  the 
author  believes,  witii  l->den  and  others,  that  they  should  be  considered  dystocia.

large  fundus  uteri;  (6)  prematurity,  a  very  common  predisposing  cause;  (7)  twin 
pregnancy. 

Breech  i)resentation  is  very  frequent  about  the  seventh  month  of  pregnancy, 
but  it  usually  changes  to  a  head,  and  the  process  may  be  repeated  several  times, 
even  up  to  a  few  days  before  lab(jr. 

Mechanism  of  Labor. — There  are  several  varieties  of  breecli  presentation, 
dep<Miding  on  the  attitude  or  posture  of  the  child:  (\)  Conipiete  or  double  bre<'eh, 
where  the  infant  nuiintains  tiie  same  attitude  as  in  vertex,  but  with  revers<'d  polarity.

both  knees  have  thus  prolapsed;  and  (c)  where  the  legs  are  extended  against  the 
trunk  and  the  feet  lie  against  the  face,  sometimes  called  "single"  breech  presenta- 
tion (Fig.  534).  These  are  all  errors  of  attitude  and  increase  the  dangers  to  mother 
and  child. 

In  conformity  with  the  system  employed   in  the  other  presentations  it   is 
possible  here,  too,  to  distinguish  six  positions  of  the  presentation,  but  in  practice

two  are  mostly  observed, — S.L.A.  and  S.D.P., — though  in  the  latter  usually  the 
back  tends  somewhat  more  to  the  side  than  behind.  The  point  of  direction  is  the 
sacrum,  and  in  following  the  mechanism  of  labor  the  genital  crease  is  used  for  the 
purpose  of  orientation,  in  the  same  way  that  the  facial  line  and  the  sagittal  suture 
are  used  for  other  jiresentations. 

Mechanism  of  Breech  Pt'esentatiou. — With  very  little  variation  the  mechanism 
of  labor  is  the  same  whether  the  complete  breech  presents  or  there  is  an  error  of 
attitude,  as  footling  or  single  breech.  For  purposes  of  study  sacrolseva  anterior 
(S.L.A.)  vnll  be  selected.  The  movements  of  the  breech  and  lower  trunk,  of  the 
slioulders  and  of  the  head,  must  be  considered,  those  of  the  shoulders  and  head 
being  more  constant  and  important. 

Even  in  primiparse  the  breech  remains  high  up  until  labor  is  quite  well  advanced, 
often  until  dilatation  of  the  cervix  is  completed  and  the  bag  of  waters  ruptured. 
The  feet  accompany  the  buttocks,  but  at  a  slight  distance,  being  held  back  by  the 
cervix  or  pelvic  brim.     Descent  is  slow  in  primiparse  because  the  soft  breech  cannot

wedge  itself  into  the  vagina  so  firmly  as  does  the  head,  and,  further,  when  the  head 
presents,  the  upper  vagina  and  the  bases  of  the  broad  ligaments,  with  the  pelvic 
connective  tissues,  are  already  dilated  and  prepared  by  the  descent  of  the  broad 
cephalic  wedge  in  the  latter  weeks  of  pregnancy.  Flexion,  the  second  movement, 
takes  place  as  soon  as  the  breech  strikes  the  perineum;  the  posterior  buttock  is 
held  back;  the  anterior  one  stems  under  the  pubis  (Fig.  536).  This  movement  is 
always  associated  with  the  third — internal  anterior  rotation.  In  S.L.A.  the  breech 
descends  in  the  left  oblique,  that  is,  the  bisiliac  diameter  lies  in  the  left  oblique 
diameter  of  the  pelvis,  the  genital  crease  lying  in  the  right,  the  anterior  hip  pointing 
to  the  right  iliopubic  tubercle,  and  l)eing  a  little  lower  than  the  posterior.  This  is 
anterior  asynclitism,  and  is  analogous  to  the  obliquity  of  Naegele.  Anterior 
rotation  occurs  by  the  anterior  hip  rotating  to  the  front  from  the  right  anterior 
quadrant  of  the  pelvis,  the  sacrum  looking  directly  to  the  left  side,  the  other  buttock 
turning  })ehind,  the  genital  fissure  now  lying  in  the  transverse.  The  causes  of  this 
movement  are  the  same  as  in  the  other  presentations  (q.  v.).     The  fourth  move-

mont  is  continued  lateroflexion ;  the  anteri(jr  liij)  stems  under  the  pubis,  tlie  ]k>s- 
terior  hip  rolls  over  the  perineum,  the  whole  pelvis  rising  up  over  the  pubis,  a  tight 
pelvic  floor  increasing  this  elevation.  External  restitution,  the  fifth  movement,  is 
not  constant.  Usually  the  anterior  hip  turns  again  to  the  right  side,  and  the 
sacrum  comes  directly  anterior,  but  s(jmetimes  the  back  remains  in  the  transverse 
anil  the  shoulders  come  out  in  this  position.  Xnu  tin-  U-gs  drop  down  and  the  back 
again  lies  in  the  oblique  (Fig.  537). 

The  movements  of  the  shoulders  are  i)reci<<  ly  similar  to  those  of  the  breech. 
Descent  occurs  with  the  bisacromial  diameter  in  the  left  obli(|ue.  If  no  attenipt 
to  aid  delivery  by  traction  from  below  is  made,  the  arms  lie  folded  clo.sely  against 
the  chest.  Stronger  pains  and  more  abdominal  muscular  exertion  are  needed  for 
delivery  of  the  shoulder-girtlle.  The  anterior  shoulder  rotates  in  the  right  anterior 
fiuadrant  of  the  pelvis  toward  the  j)ubis  and  stems  behind  it,  while  by  a  process  of 
lateroflexion  the  |)osterior  shoulder  and  arm  are  delivered.  Then  comes  the  an- 
terior shoukler  from  behind  the  pul)is,  and  if  no  assistance  is  given,  the  IkkK'  drops 
down  with  the  neck  against  the  perineum,  the  nape  against  the  sui^pubic  ligament. 


Fia.  5.37. — DtLivtRv  of  BRKKrn  to  N'avel.     .S.D.P. 


If  the  head  is  arrested  high,  the  fifth  movement,  external  restitution,  now  takes  place, 
the  back  rotating  again  to  the  side.  If  the  head  follo\\-s  the  body  closely  and  sinks 
into  the  pelvis,  the  back  may  rotate  to  the  front. 

When  the  shoulders  are  pa.ssing  the  vulva,  under  normal  circumstances  the 
head  has  entered  the  inlet.  If  the  inlet  is  contracted,  the  head  is  lu'ld  back,  and 
the  stretching  of  the  neck  permits  the  escape  of  the  shoulder-girdle,  but  not  com- 
pletely, unless  the  soft  parts  are  pushed  back  a  little  arountl  the  fetal  neck  and  up 
into  the  bony  pelvis.  When  the  head  is  well  flexed  on  the  sternum,  the  .'jame 
diameters  are  opposed  to  the  girdle  of  resistance  as  in  O.L.A..  but  in  inverted  order. 
A  ililYerence  is  also  seen  in  the  shajM*  of  the  wedge — in  occipital  pres<'ntation  the 
blunt  occiput  advances;  in  head-last  deliveries  the  narrow  planes  from  the  neck  to 
the  biparietal  go  first,  a  fact  which  explains  in  part  why  the  head  goes  through  the 
pelvis  easier  and  C|uicker  when  it  comes  out  last.  Descent,  flexion,  anterior  nota- 
tion of  the  occii)Ut  to  the  front,  occur  in  order  (Fig.  /i^iS).  all  ex|)lained  by  the  usual 
mechanisms.  The  sagittal  suture  enters  in  the  right  obli(|ue,  just  as  it  den's  in 
O.L.A.  When  the  chin  has  rotatetl  to  the  hollow  of  the  siwnim,  flexion,  the  fourth 
movement,  occurs,  the  nape  of  the  neck  being  the  center,  and  the  chin,  face,  and

forehead  coming  successively  over  the  perineum,  after  which  the  occiput  escapes 
from  behind  the  pubis. 

In  back  posterior  positions  the  mechanism  is  nearly  the  same.  Here  the  an- 
terior buttock  must  rotate  three-fourths  of  the  half-circle  in  order  to  get  under  the 
pubis,  after  which  the  mechanism  is  as  above  descril)ed.  It  has  happened  in  such 
cases  that  the  back  rotated  in  front  of  the  sacrum  to  the  opposite  side,  and  before 
delivery  is  completed  has  traversed  three-quarters  of  the  circumference  of  the  pelvis. 
I  have  never  seen  this  occur  except  when  the  posterior  foot  and  leg  had  prolapsed 
and  had  guided  this  abnormal  rotation  {vide  infra). 

Uimsual  Mechanisms. — Occasionally,  after  the  breech  is  delivered,  the  back 
rotates  beyond  the  pubis  to  the  other  side  of  the  pelvis,  an  over-rotation,  which 
has  likewise  been  observed  in  the  mechanism  of  the  shoulders  in  head  cases.  The 
remainder  of  the  child  may  come  out  with  the  back  on  the  side  opposite  that  in 
which  it  started.  Even  excessive  internal  anterior  rotation  of  the  breech  has  been 
observed,  the  body  of  the  fetus  issuing  with  the  belly  to  the  pubis.     Subsequently 


Fig.  538. — Delivery  of  After-coming  Head  in  Flexion. 


the  shoulders  enter  in  an  oblique  diameter  and  the  proper  mechanism  is  resumed. 
It  is  not  usually  possible  to  discover  the  cause  of  these  irregular  mechanisms. 

Footling  presentation  has  the  normal  mechanism,  unless  by  chance  the  pos- 
terior foot  has  prolapsed.  In  all  labors  the  tendency  is  for  the  lowest  portion  of  the 
presenting  part  to  slip  under  the  pubic  arch.  The  construction  of  the  front  part 
of  the  pelvis  and  the  arrangement  of  the  sacrosciatic  ligaments  and  the  levator  ani, 
resemble  the  ways  of  a  ferry-boat,  and  any  movable  body  placed  on  these  inclined 
planes,  propelled  from  above,  would  tend  to  go  in  this  direction.  Thus  the  breech, 
when  the  anterior  leg  has  prolapsed,  glides  without  difficulty  along  the  ways.  It  is 
different,  however,  w'hen  the  posterior  leg  has  prolapsed.  Here  the  breech  is  held 
higher,  the  anterior  buttock  impinges  on  the  horizontal  ramus  of  the  pubis,  and  the 
posterior  leg  is  prevented  from  reaching  the  anterior  inclined  plane.  It  finds  an 
easier  way  on  the  other  side  of  the  pelvis,  and  often,  not  always,  as  some  authors 
claim,  the  back  rotates  in  front  of  the  sacrum,  the  posterior  limb  now  becoming  an- 
terior and  following  out  the  favorite  mechanism,  but  on  the  other  side  of  the  pelvis. 
This  mechanism  might  also  be  explained  on  the  theory  of  Sellheim.     The  anterior

limb  fixes  the  lower  trunk  so  tliat  it  caiiiKj!  Ik-iuI  easily  towartl  the  front,  but  does 
so  toward  tlie  sacrum.  Rotation  then  takes  place  in  the  direction  in  which  the 
fetal  cylinder  can  most  reatlily  bend.  After  the  Ijreech  is  on  the  other  side  of  the 
promontory,  lateroflexion  of  the  fetal  spine  is  most  favored  in  an  anterior  direction, 
antl,  therefore,  the  fetal  cylinder  rotates  anteriorly  to  accommodate  its<'lf  to  the 
birth-canal.  In  several  instances  I  have  olwcrvcd  the  usual  mcchani.sm,  anterior 
rotation,  even  though  the  postericjr  limb  had  been  brought  douTi. 

Abnormal  rotation  of  the  i)ack  is  infretjuently  observed,  unless  the  accoucheur 
is  hasty  and  makes  premature  traction  on  the  trunk,  or  i^norantly  interferes  with 
nature's  methods.  If  the  back  does  not  nutate  to  the  front,  but  to  the  sacrum,  the 
child  descends  with  the  belly  to  the  pubis  of  the  mother.  Usually  the  natural 
powers  are  insufficient  to  deliver  the  infant  in  this  position,  and  art  has  to  aid. 
(See  Chapter  LXXl.)  Nature  may  accomi)lisli  the  birth,  the  shoulders  beinfi  force<i 
out  in  the  truusvcrsjc,  the  elbowa  and  arms  falling  from  behind  the  pubis,  and  anterior

rotation  of  the  trunk  is  enCcted  late.  As  a  rule,  the  head  jjives  the  most  trouble. 
If  it  turns  with  the  occiput  in  the  hollow  of  the  sacrum,  the  chin  to  the  pubis,  lalnir 
may  stop,  and  unless  art  aids  the  infant  will  perish.  Nature  sometimes  terminates 
these  cases  in  one  of  three  ways:  (1)  If  the  head  comes  do^\^l  well  Hexed,  the  chin 
applied  to  the  sternum,  anterior  rotation  of  the  occiput  may  occur  very  late.  Usu- 
ally in  these  instances  the  occiput  did  not  lie  directly  JM-hind.  but  nu>n'  to  one  side. 
(2)  If  the  head  is  Hexed  (Fig.  Pt'M)),  deliv«'ry  with  the  occiput  iK)sterior  occurs,  the 
root  of  the  no.se  stems  behind  tin*  pubis,  the  najx^  of  tlu>  neck,  occiput,  and  vertex 
cominj;  over,  or  through,  the  iM-rineum,  the  face  then  falling  from  Ix^hind  the  pubis. 
This  mode  of  delivery  is  facilitated  by  liftinK  the  <hild  up.  (3)  If  the  head  is  ex- 
tended, the  chin  may  catch  on  one  i)ul)ic  rannjs  (Fin.  .'>4()).  .Vrtificial  aid  is  almost

come  over  the  perineum,  pulling  the  face  after  it,  which  can  seldom  be  accomplished 
quickly  enough  to  save  the  infant. 

Single  lireech  presentations  have  a  more  laborious  delivery,  because  the  legs, 
extended  against  the  body,  act  like  a  splint  and  rob  the  fetal  cylinder  of  its  flexibility. 
Descent  and  flexion  are,  therefore,  very  slow  and  difficult.  To  be  considered  also 
are  the  smallness  of  the  advancing  wedge,  wdiich  results  in  imperfect  prc^paration 
of  the  soft  parts,  and  delay  and  danger  in  the  passage  of  the  shoulders  and  head;  the 
frequencj'  of  the  early  rupture  of  the  })ag  of  waters,  and  the  usually  weak  labor 
pains,  because  no  firm  body  presses  on  the  cervical  ganglia. 

Labor  may  be  complicated  by  the  arms  leaving  the  chest  and  being  stretched 
up  over  the  head,  or  even  crossed  behind  the  occiput  in  the  nape  of  the  neck. 
Nature  cannot  terminate  these  cases  satisfactorily.  Art  must  step  in.  (See 
Chapter  LXXI.) 

Clinical  Course. — During  pregnancy  breech  presentations  sometimes  cause 
SAinptoms  Avhich  attract  attention.  Pain  and  distress  in  the  epigastrium  may  be 
complained  of,  and  if  the  fetus  changes  its  position,  these  wall  be  relieved.    Pendulous

abdomen  is  common.     Lightening  does  not  occur.     The   fetal  movements  are 
perceived  low  in  the  belly  in  the  iliac  regions. 

Since  so  many  small  and  premature  children  come  by  the  breech,  the  time  of 
labor  is  shorter  than  with  cephalic  presentations,  but,  counting  only  full-sized  in- 
fants, labor  is  actually  longer  in  breech  cases,  and  this  is  especially  true  of  primi- 
parge.  This  increase  of  the  length  of  labor  is  all  in  the  first  stage,  the  second  stage 
progressing  very  rapidly,  seldom  taking  more  than  eight  minutes,  and  usually  less 
than  four.  The  breech  remains  high  and  relatively  immobile  until  the  cervix  is 
completely  dilated;  then,  with  the  rush  of  the  waters,  it  comes  quickly  down  to  the 
perineum.  The  actual  delivery  is  shorter  and  less  painful  than  head  labors.  Pre- 
mature rupture  of  the  membranes  is  common,  and  this  renders  still  slower  the  dila- 
tation of  the  OS.  In  primipara^  lal)or  may  be  very  tedious,  and  the  second  stage, 
0"\ving  to  rigidity  of  the  vagina  and  perineum,  may  be  so  prolonged  that  the  life 
of  the  fetus  is  much  endangered.  In  cases  of  complete  breech  the  large  foregoing 
part  prepares  the  cervix  and  pelvic  floor  for  the  passage  of  the  head.  In  footling 
or  single  breeches  these  parts  are  poorly  dilated,  and  while  the  slender  trunk  slips 
through  easily,  the  head  is  almost  always  arrested,  the  child's  life  l)eing  lost,  or  the 
ti-ssues  being  torn  as  a  result.     JMeconium  may  escape  freely  during  breech  de-

THE    PATHOLOGY    OF    LABOR 


Plastic  Changes. — The  caput  succedaneum  is  found  on  the  anterior  hip,  but 
may  spread  all  over  the  buttocks.  In  boys  the  penis  and  scrotum  may  be  enor- 
mously edematous  and  black  and  blue  from  extravasated  l)lood.     In  girls  there  may 

be  a  moderate  vulvitis,  with  leukor- 
rhea,  for  a  few  days.  If  the  leg  has 
been  doA^ai  for  any  length  of  time, 
it  swells  and  show^s  minute  hemor- 
rhages besides  the  severe  congestion. 
All  this  disappears  within  a  week. 
Ordinarily,  the  child's  head  is  not 
molded,  but  presents  the  round 
shape  it  had  in  utero — this  in  mul- 
tiparas and  when  the  breech  pres- 
entation was  developed  just  before 
labor  began.  If  the  child  had  lain 
a  long  time  in  this  position,  especi- 
ally if  the  mother  was  primiparous, 
or  if  the  labor  had  lasted  a  long 
time  after  the  rupture  of  the  mem- 
branes, distinct  evidences  of  mold- 
ing will  be  discoverable  on  the  head. 
This  may  take  the  form  of  a  dolicho- 
cephalus,  which  Avas  especially 
brought  out  by  Fritsch,  the  head 
having  been  pressed  down  by  the 
fundus  uteri  or  one  or  the  other 
side  of  the  head  may  be  flattened. 
If  the  mother  had  a  pendulous  ab- 
domen, the  side  of  the  head  which 
lay  posterior  will  show  the  flattening,  as  in  this  case  the  head  will  be  inclined  toward 
the  anterior  shoulder.  If  the  abdominal  wall  held  the  head  up  firmly,  the  side  of 
the  head  which  lay  anteriorly  will  be  flattened,  the  lateral  inclination  then  being 
onto  the  posterior  shoulder.  The  sterno- 
cleidomastoid and  other  muscles  on  the 
side  opposite  that  showing  the  flattening 
may  be  shortened,  producing  a  wry-neck. 
In  cases  of  oligohydramnion  this  is  the 
rule.  Great  importance  must  be  attached 
to  this  congenital  shortening  of  the  neck 
muscles,  because  if,  during  delivery,  too 
much  traction  is  made  on  them,  they  will 
tear,  hematoma  or  myositis  resulting. 
Permanent  wry-neck,  while  seldom  due 
to  injury  of  a  normal  muscle,  and  sel- 
dom following  a  hematoma  of  the  mus- 
cle, is  often  the  result  of  this  congenital 
shortening,  either  with  or  Avithout  in- 
jury. 

Diagnosis. — Unless     labor     is     ad- 
vanced and  the  pains  are  very  strong  and 

frequent,  rendering  the  utf^'us  rigid,  the  external  (examination  will  l)e  sufflcient  for 
diagnosis.  The  ovoid  is  longitudinal,  ])ut  the  upper  ])()rtion  of  the  uterus  is  broader 
than  the  lower  and  runs  to  the  side  on  which  the  head  lies,  a  three-cornered  effect 
being  produced.     Over  the  inlet  no  hard,  round  body  is  to  be  found,  but,  instead,  a

are  always  above  the  level  of  the  navel,  an  important  diagnostic  point.  (Jften  the 
head  can  be  grasped  between  the  two  hands,  or  even  measured  with  a  cephalo- 
meter,  but  other  times  it  can  be  felt  only  by  tapi)inK-palpation — and  occasion- 
ally it  is  to  be  recognized  as  a  body  slunving  ballottement.  Viujiunlbi,  the  fingers 
have  tobedeejily  inserted  before  the  presenting  part  can  be  touched,  tln'pel\is  being 
empty.  A  convex  hard  tumor  in  the  vaginal  vault  is  not  felt ;  instead,  a  njundish, 
soft  mass  of  prominences  and  depressions,  in  which  the  exatniner  can  distinguish 
the  buttocks  with  a  crease  between  them,  and  at  one  end  a  pointed  bone — the 
sacrum.  Three  or  four  small  prominences  on  this  will  identify  the  bone  and  show 
the  directi(jn  of  the  pelvis,  but  for  additional  assurance  the  finger  may  follow  the 
genital  crease  to  the  child's  genitalia,  when  the  scrotum  or  vulva  will  be  distinguish- 
able. The  finger  at  the  anus  may  feel  the  tuberosities,  and,  if  inserteil,  may  l>e 
covered  with  meconium,  of  course,  after  the  membranes  are  broken.  Higher  up  and 
to  one  side  one  or  l)oth  feet  may  be  felt,  though  usually  (jnly  the  heels  are  within 
reach  of  the  finger.  Suspicion  having  been  aroused  by  the  empty  ju-lvis,  the  ac- 
coucheur ought  to  have  no  difficulty  in  recognizing  the  breech,  l)Ut  mistakes  are  very 
common,  the  breech  being  confused  with  the  shoulder,  the  face,  and  the  bag  of  waters. 
The  closed  axilla  and  the  costal  gridiron  will  identify  the  shoulder,  and  the  saddle  of 
the  nose  and  orbital  ridges,  the  nostrils,  and  the  gums,  will  prove  the  face.  The 
diagnosis  of  the  jiosition  of  the  breech  is  nuide  from  the  location  of  the  sacrum.  It 
is  atlvisable  not  to  introduce  the  finger  into  the  anus  or  into  the  vulva  of  the  fetus. 

In  single  breech,  when  the  feet  are  extendetl  up  to  near  the  face,  they  may  often 
be  felt  there  from  the  outside.  The  uterus  is  longer  anil  straighter  compared  with 
the  rounded  outline  when  the  child  is  normally  flexed.  \'aginally,  the  feet  cannot 
be  felt;  the  anus  is  nearer  the  middle  of  the  pelvis,  and  the  straightened  thighs 
disclose  the  direction  of  the  extremities. 

In  footling  the  accoucheur  should  follow  the  prolapsed  extremity  up  to  the 
pelvis  and  make  the  diagnosis  on  general  lines,  the  direction  of  the  big  t<K'  and  the 
flexure  of  the  knee  giving  added  informaticm.  One  should  not  hastily  conclude 
that  a  breech  presentation  exists  when  the  foot  is  discovered — it  may  have  prolapsed 
with  the  head. 

Prognosis. — Statistics  give  the  maternal  mortality  as  slightly  higher  than  in 
occipital  i)resentations.  the  reasons  being:  ( 1)  Labor  is  longer  and  internal  t'xamina- 
tions  are  more  freciuent,  both  incrca.sing  the  ilangt-rs  of  inl'ecti«)n;  y'2)  etTacement 
and  dilatation  of  the  cervix  are  not  so  perfect,  hence  lacerations  are  more  conunon; 
(3)  since  the  head  comes  rapidly  through  the  unprepared  jM'lvic  floor,  rupture  of 
the  perineum  is  freciuent,  extending  often  through  the  rectum,  and  these  are  not 
always  errors  of  art ;  (4)  disturbances  of  the  mechanism  of  labor  are  fn-cjuent.  ami 
since  they  demand  the  introduction  of  the  hand  or  other  operative  m«'a.sun*s.  the 
prognosis  for  the  mother  is  doubtful;  (."))  jiostpartum  hemorrhage  is  incn':iM'd. 
Most  of  these  dangers  may  be  eliminated,  and  all  may  be  minimized  by  the  api)lica- 
tion  of  the  rules  of  good  obstetrics. 

For  the  child,  breech  j^resentation  is  certainly  dangerous,  the  mortality  tables 
showing  from  0  to  1.')  jmt  c<'nt.  of  deaths.  With  proj^r  treatment,  not  over  .")  jxr 
cent,  of  children  should  ilie  in  uncomplicated  cases.  .Vsphyxia  causes  most  of  the 
deaths,  but  fracture  of  the  skull  and  injurii's  to  the  neck  and  spine  also  account  for 


614  THE    PATHOLOGY    OF   LABOR 

many  of  them.  The  asphyxia  is  caused  by  compression  of  the  cord  between  the 
body  and  the  cervix  after  the  breech  is  born,  or  by  its  being  stretched  upward  from 
between  tlio  child's  legs,  by  premature  detachment  of  the  placenta,  by  compression 
of  the  placenta  by  the  hard  head,  and  b}'  delay  in  delivery  due  to  rigid  soft  parts. 
In  vertex  presentations  the  soft  breech  lies  against  the  placenta  and  exerts  no  com- 
pression, and  if  the  placenta  loosens  before  the  delivery  of  the  trunk,  the  head  is 
already  out,  or  nearly  out,  so  that  the  child  may  breathe,  whereas  in  breech  presen- 
tation the  first  inspiration  sucks  in  liquor  amnii,  blood,  or  anything  which  lies  near 
the  mouth.  It  is  possible,  too,  that  the  cold  air  striking  the  body,  or  the  manipula- 
tions of  the  attendant,  excite  premature  respirations.  A  child  will  live  five  to  ten 
minutes  after  the  breech  is  delivered,  there  being  very  few  cases  on  record  where  a 
child  was  born  alive  fifteen  minutes  after  the  breech  passed  the  vulva.  It  is  ad- 
visable, therefore,  not  to  allow  the  progress  to  be  too  slow  after  the  breech  has 
passed  the  vulva;  on  the  other  hand,  undue  haste  must  be  avoided  because  of  the 
danger  of  injury  to  the  fetal  person.  Fracture  of  the  femur,  of  the  pelvis,  rupture  of 
the  filled  colon,  of  the  liver,  fracture  of  the  humerus,  of  the  clavicle  (common), 
overstretching  of  the  cervical  spine,  even  fracture  of  the  spine,  pulling  the  nerves 
out  of  the  spinal  cord  (Erb's  paralysis),  rupture  of  the  sternocleidomastoid,  disloca- 
tion of  the  atlas — all  these  and  more  have  been  observed.  In  old  primiparse  or  such 
parturients  as  have  rigid  soft  parts,  these  dangers  are  augmented  and  require  special 
treatment  for  their  prevention. 

Treatment. — If  breech  presentation  is  discovered  during  the  last  few  weeks  of 
pregnancy,  it  is  advisable  to  make  gentle  efforts  to  bring  the  cephalic  pole  over  the 
inlet.  The  patient  is  instructed  to  assume  the  knee-chest  posture  several  times 
daily,  and,  when  reposing,  to  lie  on  that  side  to  which  the  head  points;  for  example, 
in  S.L.A.  on  the  right  side.  The  accoucheur  may  also  try,  by  gentle  external  man- 
ipulation, to  bring  the  head  down,  though  his  efforts  are  not  always  rewarded  by  a 
permanent  change  of  the  presentation. 

Watchful  expectancy  is  the  treatmerit  during  labor.  Older  writers  usually  ad- 
vised version,  changing  the  breech  to  cephalic  presentation  by  internal  and  external 
manoeuvers,  and  especially  in  old  primiparse.  While  admitting  that  a  head  pres- 
entation is  highly  desirable,  and  particularly  in  aged  primiparse,  unfortunately  the 
operation  in  them  is  more  than  usually  difficult  and  unsuccessful.  Where  the  soft 
parts  appear  very  rigid,  and  when  the  child  is  large,  it  is  wise  to  prepare  the  former 
for  the  rapid  stretching  they  are  about  to  receive.  This  is  done  l)y  colpeurysis,  a 
Carl  Braun  colpeurynter  being  placed  in  the  vagina  and  filled  with  12  to  16  ounces 
of  weak  antiseptic  solution.  By  the  stretching  it  causes,  and  by  its  presence,  the 
pains  are  strengthened,  the  tissues  softened  and  dilated,  and  if  it  is  expelled  by  the 
powers,  the  pelvic  floor  outlet  is  enlarged  as  by  the  passage  of  the  first  twin.  An- 
other favorable  action  of  the  colpeurynter  is  the  preservation  of  the  bag  of  waters, 
which  is  so  highly  desirable  in  breech  cases. 

Otherwise  the  treatment  of  the  first  stage  is  not  at  variance  from  the  usual. 
When  the  second  stage  draws  near,  the  accoucheur  should  have  everything  ready 
for  all  the  emergencies  of  an  operative  delivery.  This  provision  consists  of  a  set 
of  instruments — forceps,  perineorrhaphy  instruments,  etc.,  hot  bath,  towels,  and 
tracheal  catheter  for  treating  the  asphyxiated  child,  a  table  on  which  to  place  the 
parturient  for  delivery,  and  sufficient  assistants.  (To  avoid  repetition,  the  reader 
is  referred  to  the  chapter  introducing  the  subject  of  Operative  Obstetrics.) 

When  the  breech  begins  to  distend  the  vulva,  the  woman  is  placed  on  the  table, 
her  limbs  supported  by  assistants,  and,  in  the  absence  of  trained  help,  ])y  courageous 
neighbors — not  the  husband,  as  he  is  likely  to  faint.  As  the  breech  emerges  the 
accoucheur  should  restrain  the  desire  to  aid  by  traction,  but  should  encourage  the 
woman  to  bear  down  strongly.  The  foot,  if  it  is  down,  or  the  breech  is  to  be  wrapped 
in  a  warm  towel  as  it  comes  out.     Nothing  more  is  done,  the  operator  sitting  by 


ANOMALIES   OF   THE    PASSENGERS  615 

■with  sterile  hands.  An  assistant  listens  to  the  heart-tones  every  two  minutes,  and 
any  weakening  or  irregularity  is  the  signal  for  rapid  delivery.  If  the  foot  is  out, 
the  baby's  pulse  may  be  felt  in  the  antericjr  tibial  artery.  Anesthesia  is  not  used 
unless  the  patient  is  very  unruly,  because  her  efforts  are  netnled  safely  to  <'xpel  the 
infant.  In  primipara*  with  rigid  jxlvie  floor,  or  with  a  big  baby,  it  is  my  own  prac- 
tice to  perform  a  deep  unilateral  episiotomy  even  l)efore  the  head  is  to  Ix'  lx>m.  I 
prefer  it  to  a  perineal  tear  for  reasons  that  have  l)een  mentioned.  It  saves  delay 
in  the  deliver}-  of  the  shoulders  and  the  h<-a<l,  and  surely  has  saved  many  babies' 
lives,  as  well  as  j)revented  com|)lete  lacerations  of  the  jxTineum. 

When  the  navel  appears,  the  rest  of  the  birth  nmst  l>e  rapidly,  but  not  pre- 
cipitately, completed.  The  woman  is  told  to  bear  down  with  all  her  power.  If  she 
is  anesthetizetl  or  eamiot,  the  a.ssistant,  spreading  his  hands  evenly  over  the  fundus, 
exerts  pressure  in  the  axis  of  the  inlet.  This  stn-ngthens  the  uterine  and  abdominal 
action,  and  keeps  the  arms  against  the  chest,  preventing  their  ascent  alongside  the 
head,  which  would  much  complicate  the  deliver>'.  If  both  fail,  manual  aid  is 
rendered.  Manual  aid  means  the  delivery  of  the  shoulders  anil  head,  after  nature 
has  accomplishetl  the  expulsion  to  the  navel.  It  nmst  l)e  very  sharjily  distinguished 
from  "l)reech  extraction,''  wiiich  means  l)ringing  tlown  the  breech  in  some  way  and 
delivery  of  the  whole  child  from  within  the  birth-canal.  (Kor  the  details  of  these 
manoeuvers  see  Chapter  LXXI.)  Should  the  natural  powers  avail  for  deliverj',  the 
accoucheur  receives  the  child  as  it  emerges,  and  when  the  mouth  is  visible  in  the 
vulva,  he  sjionges  the  nmcus  from  it  ami  restrains  the  head  from  making  a  Uh)  rapid 
exit  through  the  i)elvic  floor,  .\fter  delivery  of  the  chilil  the  accoucheur  should  be 
prepared  to  treat  postpartum  hemorrhage  and  all  kinds  of  lacerations. 


TRANSVERSE  PRESENTATIONS 

Another  error  of  polarity  of  the  fetus  is  transverse  presentation.  Here  the 
long  a.xis  of  the  child  cros.ses  the  long  axis  of  the  mother.  It  is  rare  that  they  cross 
at  a  right  angle:  almost  always  the  fetal  cylimler  is  oblicjue  to  the  motlu-r's  spine. 
Usually  the  head  is  the  lower  pole,  but  in  .some  ca.<es  the  breech  is  nearer  the  inlet. 
Often  earl}'  in  labor  the  head  is  found  deviated  from  the  inlet  anil  lying  in  one  iliac 
fossa.  The  breech  may  be  found  similarly  placed.  These  are  calleil  "oblique  pres- 
entations," or  "deviated  head,"  or  "deviated  breech"  ])re.sentations.  and  repre- 
sent a  stage  of  the  transition  from  l()ngitu<linal  to  a  transverse  pres(>ntation.  By 
external  maniinilation  and  proper  posture  of  the  woman  the  abnormal  mechanism 
may  be  corrected. 

Since  the  shoulder  is  the  jmrt  that  usually  enters  the  ix'lvis  first,  most  authors 
call  the  ca.ses  under  consideration  "shoulder  i)re.sentations,"  l)ut  the  back,  the  side, 
the  belly,  or  the  four  extremities  may  i)re.sent.  True,  all  the  last  four  are  exceed- 
ingly rare. 

Etiology.— Shoulder  pre.-^entations  occur  about  once  in  2(X)  cas«>s,  in  multipara* 
oftener  than  in  jirimipara?,  and  in  prenuiture  lalM)r  oftener  than  at  term. 

In  general,  anything  that  will  ]>revent  the  engagement  of  the  head  in  the  jH'lvis. 
also  any  condition  conferring  an  extraordinary  degree  of  mobility  on  the  fitus,  will 
cause  transverse  presentation.  The  causes  may  U'  primary,  and  lie  in  some  mal- 
formation of  the  maternal  parts  or  of  the  fetus,  or  s<H'ondar>-,  In-ing  proiln<  •  -1  '.v 
some  act  or  accident  during  lalM)r.     The  most  imjwrtant  are: 

1.  Contracted  p«'lvis.  Transverse  pre.-^'iitations  iH'cur  twice  as  often  m  con- 
tracted pelvis  as  in  normal  jwlves.  So  con.stant  is  this  that  when  called  to  a  case 
of  transverse  presentation,  the  first  thought  is  of  .-^ome  obstruction. 

2.  An^ihing  in  the  ix'lvis  jm'venting  the  engagement;  for  example,  ovarian 
tumor,  til)roid,  the  placenta,  full  bladder,  or  rectum.  It  sometimes  hapjiens  that 
after  emptying  a  full  biadder  the  fetus  turns  of  itself  into  a  normal  ixwition. 


616 


THE    PATHOLOGY    OF   LABOR 


3.  Twins  displacing  each  other. 

4.  Multiparity,  hydramnion,  premature  labor.  Here  the  child  is  free  to  move, 
and  the  factors  making  for  a  longitudinal  presentation  are  absent. 

5.  Uterus  bicornis,  uterus  arcuatus,  partly  septate  uterus.  A  cause  of  repeated 
shoulder  presentations. 

6.  Anomalies  of  the  fetus,  for  example,  double  monsters. 

Of  the  secondary  causes,  accident  plays  the  stronger  role.  The  fetus  happens 
to  be  in  an  unfavorable  position  when  the  bag  of  waters  ruptures;  the  shoulder 
is  forced  into  the  pelvis,  and  a  transverse  presentation  results.     The  dislocation 


Fig.  545. — Shoulder  Presentation.     Sc  L.A. 


of  a  second  twin  by  the  first  is  also  to  be  reckoned  here,  and  dislocation  of  the  child 
by  an  overfilled  or  badly  placed  colpeurjniter  also. 

Often  several  of  these  factors  will  combine  to  cause  the  malpresentation. 
In  some  cases  the  fetus  seems  to  keep  its  embryonal  position  in  utero,  or  the  uterus 
is  not  tense  enough  to  adapt  the  fetal  ovoid  to  itself. 

Mechanism  and  Clinical  Course. — Although  the  back  or  the  belly  may  lie 
across  the  inlet,  the  sliould(>r  is  the  part  which  most  often  enters  the  pelvis  first, 
so  that  usually  we  speak  of  shoulder  presentation.  On  the  shoulder  these  landmarks 
are  to  be  distinguished,  and  they  are  useful  for  diagnosis — the  scapula,  the  acromion 
process,  the  axilla,  and  the  clavicle.  The  scapula  is  selected  as  the  point  of  direc- 
tion.

to  deal  with.  The  relations  of  the  hack  and  of  the  head  to  the  inlet  are  most  im- 
portant in  the  study  of  the  meclianism  (jf  labor.

Attitude. — Early  in  labor  we  find  the  usual  posture  of  tlexion  conunon  to  r).L.A., 
the  chin  on  th(>  sternum,  arms  cros.sed  over  the  chest,  legs  crossed  over  the  l)olly, 
but  later  many  changes  are  observetl.  Commonest  is  the  prolap.s<^  of  the  lower 
arm,  rarely  the  two,  and  still  more  rarely  the  upjH'r  one  alone.  Prolap.<e  of  the 
cord  is  not  infrequent.  When  the  uterus  luis  worked  on  the  fetal  ovoid  for  any 
length  of  time,  the  hitter  is  compres.»*ed  from  side  to  side,  the  hea«l  nears  the  breech, 
and  the  ovoiil  is  ma<l.'  more  globular.  ()cca.«*ionally  the  fetal  body  is  t>\-isted  on 
its  long  axis,  so  that,  while  the  shoulder  lies  deep  in  the  pelvis,  the  belly,  instead  of

looking  to  the  sacrum,  looks  directly  upward,  and  the  legs  also  are  turned  forward. 
The  neck  may  also  be  twisted;  in  one  of  my  cases  the  child's  head  was  deflected, 
resembling  the  attitude  of  face  presentation.  Ahlfcld  noticed  this  in  a  case  of 
breech  presentation. 

Course. — Shoulder  presentations  are  always  pathologic.  True,  the}'  sometimes 
temiinate  spontaneously,  but  with  rare  exceptions  the  children  all  die,  and  often 
the  mother,  too,  so  that  they  are  cases  of  dystocia  and  demand  the  aid  of  art. 
Early  in  pregnane}^  transverse  presentation  is  the  rule.  Even  in  the  last  month, 
in  multiparae,  it  is  occasionally  found,  l)ut  rectifies  itself  before  labor  begins,  the 
process,  of  which  the  accoucheur  usually  has  no  knowledge,  being  called  spontatieous 
rectification.  This  means  that  the  contractions  of  pregnancy  have  changed  the 
polarity  of  the  fetal  ovoid,  and  the  process  may  be  aided  by  proper  position  of  the 
mother.  If  it  does  not  take  place  during  pregnancy,  a  longitudinal  presentation 
may  be  brought  about  spontaneously  during  the  first  stage  of  labor,  or  even  at  the 
beginning  of  the  second  stage  (very  rarely).     This  is  called  "spontaneous  version," 


Fig.  .547. — Labor  in  CoxorPLicATO  Corpore.     Roederer's  Method  (Zangemeister) . 

is  not  at  all  a  constant  occurrence,  and  in  practice  is  never  relied  on.  Both  of  these 
processes  are  more  likely  where  the  fetus  is  freely  moval^le,  as  in  polyhydramnion, 
and  where  the  presenting  part  cannot  easily  enter  the  inlet,  as  in  contracted  pelvis. 
As  a  rule,  when  a  change  of  presentation  is  brought  about,  the  head  comes  down, 
but  sometimes  the  breech  may  come  to  lie  over  the  inlet. 

In  order  to  study  the  mechanism  of  transverse  presentation  a  case  A\ill  be 
assumed  where  no  aid  is  rendered.  The  pains  are  likely  to  be  slow  and  weak,  since 
no  hard  part  presses  on  the  cervix,  but  the  bag  of  waters  often  ruptures  early,  be- 
cause the  membranes  are  exposed  to  the  full  force  of  the  uterine  contraction.  The 
lower  uterine  segment  is  not  cut  off  from  the  general  cavity  of  the  uterus,  so  after 
the  rupture  of  the  bag  of  waters  all  the  liquor  amnii  escapes,  since  there  is  nothing 
to  hinder.     This  is  a  bad  accident,  especially  if  the  cervix  be  undilated. 

When  the  uterus  has  no  more  liquor  amnii,  the  walls  apply  themselves  to  the 
fetus  very  closely.  Two  conditions  may  now  be  observed:  first,  there  may  be  no 
pains  at  all,  the  uterus  simply  lying  apposed  to  the  fetus  in  a  condition  which  was

C19 


called  1a-  Kiliuii  " passive  contraction."  The  walls  arc  distensible;  the  hand  can 
be  easily  introduced,  and  even  version  performed.  This  condition  carries  no  dan- 
ger to  the  fetus  or  the  mother,  may  last  a  few  hours  or  a  few  tiays,  but  generally 
passes  over  into  the  other  state,  either  spontaneously  or  a.s  the  result  of  brusk 
manipulations.  This  first  condition  has  nothing  to  do  with  the  so-called  tetanus 
uteri,  to  be  described  presently. 

Sooner  or  later,  u.sually  the  result  of  improper  treatment,  the  pains  begin,  and 
very  soon  accjuire  a  dangerous  violence.     They  force  the  .shoulder  into  the  jjelvis,

the  fetus  is  folded  together,  the  breech  nears  the  head,  the  ovoid  Incoming  more 
glol)ular.  If  the  fetus  is  small  or  macerated  and  the  pelvis  large  enough,  the  uterus, 
aided  by  powerful  elTorts  of  the  mother,  may  succeed  in  exi^'lling  it.  This  is  called 
"spontaneous  evolution,"  and  is  the  liu^t,  least  likely,  anti  most  dangerous  method 
nature  has  of  overcoming  th(»  malpresentation.  Sixintaneous  evolution  pursues 
tliree  methods,  nanu-d  res|)ectively,  after  the  men  who  first  accurately  descrilwd 
them,  Roeilerer's,  Douglas',  and  Denman's.  According  to  the  first,  which  usually 
occurs  without  prolapse  of  the  arm,  the  child  is  folded  like  the  letter  V,  the  shoulder 
and  back  advancing,  the  head  pr(\>^sed  deep  into  the  chest  and  abdomen  (Fig.  547).

THE    PATHOLOGY    OF    LABOR 


In  Douglas'  method,  which  oftener  occur.s  in  l)ack  anterior  positions  with  prolapse 
of  the  arm,  the  fetal  mass,  under  the  influence  of  strong  pains,  becomes  pointed, 
the  head  is  arrested  above  the  inlet  and  rotates  to  the  pubis,  the  neck  is  applied 
to  the  brim,  and  very  much  lengthened.  Now  the  chest,  abdomen,  and  breech 
roll  down  alongside  the  shoulder,  the  legs  drop  out,  then  the  other  arm,  and  finally 
the  h(^ad  appears  (Fig.  548).  In  the  rarest  of  all  three  mechanisms,  Denman's, 
which  is  usually  taken  by  back  ])osterior  ])ositions,  the  head  rotates  behind,  and,  as 
the  breech  descends,  the  shoulder  ascends  in  the  pelvis,  a  sort  of  version  taking 
place  in  the  pelvic  cavity,  the  breech  finally  coming  down  and  out  (Fig.  549).  All 
three  mechanisms  occur  at  the  end  of  the  second  stage ;  all  three  require  exception- 
ally favorable  conditions — that  is.  large  pelvis,  small,  soft,  molding  fetus,  strong 
pains,  and  great  integrity  of  uterine  muscle,  and  in  none  of  the  three  will  a  full-

term  child  be  delivered  alive.  Zangemeister  reports  the  heaviest  child  delivered 
alive — weight,  2700  gm.  Usually  the  fetuses  are  macerated  or  very  small.  Death 
is  due  to  compression  of  the  vital  organs  in  the  chest  and  head,  interruption  of  the 
placental  circulation  by  the  almost  constant  uterine  contractions  or  by  dislocation 
of  the  placenta  in  the  retracted  fundus  uteri.  Since  the  child  is  almost  invariably 
lost  and  the  mother  exposed  to  risks  of  imminent  death  during  these  processes, 
they  are  never  to  be  relied  on  in  practice. 

Daily  experience  shows  that  nature  is  generally  i)owerless  safely  to  accomplish 
delivery  in  full-term  cases,  and  labor  is  arrested  with  the  child  forced  together  in 
a  compact  mass,  solidly  blocking  the  pelvis.  If  the  arm  hangs  out,  it  swells  up, 
sometimes  to  the  size  of  a  man's  wrist,  shows  blisters  or  even  peeling  skin,  the 
child  dies,  and  the  vulva  becomes  edematous,  bluish  ])lack,  and  even  gangrenous. 

The  pains  become  irregular  and  tumultuous,  the  distinction  between  pain  and

pause  is  not  marked,  and  the  uterus  is  in  a  state  of  constant  contraction.  The 
patient  heconies  anxious,  and  complains  of  continual  pain  and  Kff'at  tenderness 
over  the  lower  part  of  the  uterus.  Pulse  and  ti-miwrature  hcKin  t<j  rise.  The 
uterus  draws  up  over  the  child;  the  mu.scle  becomes  thick  alM>ve  tin-  contraction-

This  condition  is  called  a  ''neglected  transverse  -presentation"  and  the  uterus 
is   in   a  state   of  threatened  rupture.     Where   the  fundus,  thick   and  contracting,

a  groove  or  depression  can  be  seen  and  felt  on  tlu*  abdomen,  rumiing  from  side  to 
side  about  th«'  level  of  the  navel.  This  is  the  ominous  retraction-ring,  sometimes 
called  contraction-ring  (Fig.  697).  .\i)ove  this  groove  the  parts  can  W  |>oorly  felt; 
below  this  groove  the  fetus  is  easily  felt.  I'nless  aid  is  given,  the  uterus  ruptures 
and  the  mother  dies  of  shock,  hemorrhage,  or  peritonitis.  The  uterus  may  rupture 
during  an  attcMupt  at  version.  Death  t)f  the  child  occurs  from  tlu^  interru|>tion  of 
the  placental  circulation  and  from  compres.>iion  before  rupture.  If  not.  it  ilies 
after  the  rupture,  and  may  be  in  ]>art  or  in  toto  extrudetl  through  the  rent  into  the

abdominal  cavitj'.  Or  the  woman  may  die  of  shock  and  exhaustion  before  the 
rupture  takes  place. 

If  the  uterus  should  not  rupture  soon, — and  the  tendency  varies  with  different 
women  (in  primiparae  there  is  not  so  much  tendency  as  in  multiparse), — the  pains 
grow  weaker  and  irregular,  the  cavity  of  the  uterus  becomes  infected — from  the 
vagina,  from  the  air,  from  the  exposed  arm,  or  from  the  examining  fingers;  the 
fetus  and  the  little  liquor  amnii  left  begin  to  decompose;  gas  is  developed  in  the 
uterus  and  distends  it.  The  condition  is  called  tympania  uteri  or  physometra. 
General  infection  is  soon  apparent,  temperature  and  pulse  mounting  rapidly,  the 
features  change,  a  subicteric  hue  develops,  and  the  poor  woman  dies  in  septic 
collapse.  If  successfully  delivered,  the  sepsis  may  continue,  but  recovery  is  un- 
likely when  much  damage  has  been  done  to  the  structure  of  the  parturient  canal. 

Another  condition  that  occurs,  as  well  with  cephalic  as  with  transverse  pres- 
entation, is  called  tetanus  uteri.  It  is  due  to  too  early,  brusk,  and  ^'unnecessary 
manipulations  on  the  uterus  or  cervix,  and  especially  to  the  administration  of  ergot. 
The  uterus  is  in  one  continual  spasm.  Occasionally  a  pain  will  increase  the  spasm. 
One  finds  the  uterus  hard  all  over,  very  tender,  and  the  woman  in  continual  pain; 
the  cervix  is  red,  dry,  and  hot;  the  vagina  also  is  dry  and  hot.  Labor  is  at  a  stand- 
still, since  in  this  condition  the  cervix  will  not  dilate,  and  it  is  generally  impossible 
to  turn  the  baby  so  as  to  extract  it.  There  is  no  danger  of  spontaneous  rupture, 
but  the  baby  dies,  due  to  the  interruption  of  the  placental  circulation,  and  unless 
something  is  done  the  mother  dies  of  sepsis. 

Fortunately  in  this  country,  and  also  in  Europe,  cases  of  "neglected  transverse 
presentation"  are  becoming  rare.  The  evil  results  of  neglect  must  emphasize  the 
importance  of  early  diagnosis  and  consistent  treatment. 

Diagnosis. — During  pregnancy  abdominal  palpation  gives  the  best  results,  while 
vaginally  nothing  but  the  empty  pelvis  is  felt.  During  labor  the  conditions  are 
reversed  because  the  contracting  uterus  covers  up  the  fetal  parts. 

Abdominally. — (1)  No  longitudinal  ovoid,  but  one  more  or  less  transverse,  and, 
in  contradistinction  to  uterus  arcuatus,  the  broad  portion  is  just  above  the  inlet, 
not  above  the  navel,  as  with  arcuate  uterus.  (2)  Over  the  inlet,  nothing — the 
space  is  empty  and  the  finger-tips  may  come  together  over  the  pelvis.  (3)  In  the 
fundus  likewise  nothing;  at  most,  some  small  parts  or  a  deep  furrow.  (4)  The 
back  is  in  neither  flank,  and  the  hand  must  search  elsewhere.  Three  of  the  four 
cardinal  principles  of  the  diagnosis  of  presentation  being  negative,  the  diagnosis 
must  rest  on  the  first,  plus  other,  special  findings.  In  scapulolseva  anterior  the 
head  will  be  found  on  the  left  side,  low  in  the  flank,  and  it  is  recognized  by  its  being 
large,  hard,  rounding,  sometimes  with  ballottement.  The  breech  is  high  up  to  the 
right  behind,  the  small  parts  in  the  fundus  to  the  right  of  the  median  line,  the  heart- 
tones  loudest  a  little  to  the  left  and  below  the  navel.  It  is  easy  to  outline  the  dorsal 
plane  in  front.  In  Sc.D.P.  the  head  is  deep  in  the  right  flank,  the  breech  under  the 
spleen,  no  back  can  be  outlined,  but,  instead,  the  region  of  the  navel  seems  filled 
with  small  parts,  and  the  heart-tones  are  to  the  right  of  the  navel,  about  on  a  level 
with  it. 

Vaginally. — An  empty  vaginal  vault  immediately  awakens  suspicion  of  some- 
thing abnormal.  Sometimes  the  bag  of  waters  hangs  down  like  a  stocking,  filling 
the  pelvis,  and  the  attempt  to  feel  something  through  it  may  rupture  the  membranes, 
which  would  be  very  unfortunate.  The  cervix  hangs  down  like  a  cuff,  and  collapses 
in  the  interval  between  pains.  After  labor  has  progressed  a  short  while  the  shoulder 
is  more  accessible,  and,  especially  if  the  membranes  are  ruptured,  all  the  landmarks 
may  be  discovered.  These  are  the  acromion  process,  the  scapula,  the  clavicle,  and 
the  axilla.  The  cUrection  in  which  the  axilla  is  closed,  that  is,  its  apex,  points  to 
the  fetal  head.  By  noting  whether  the  hard  edge  of  the  scapula  looks  to  the  pubis 
or  to  the  sacrum  we  are  enabled  to  say  that  the  back  lies  to  the  front  or  to  the  rear. 


ANOMALIES   OF   THE    PASSENGERS 


023 


In  Sc.L.A.  the  apox  of  the  axilla  points  to  tin-  left,  tin-  cclfr,.  ,,f  tho  scapula  lies  to  the 
front,  and  the  costal  gridiron  to  the  rear.  Pnjlapse  of  the  arm  or  ellx)W  will  aid 
in  diagnosis.  When  the  hand  is  down,  the  direction  of  the  thuinl)  and  the  l)end  of 
the  elbow  will  he  toward  the  child's  alxhjinen.  \W  trying  to  shake  hands  with 
the  child  it  is  jjossihle  to  decide  which  hand  is  prolapsed.  In  Sc.L.A.  the  right  ann — 
the  lower  one — almost  always  falls  d(jwn;  thcrefcjre  if  you  find  the  liead  <ni  the  left 
side  and  the  right  arm  down,  it  is  safe  to  diagno.se  this  position.  While  nmch  can 
be  learned  from  the  position  of  the  arm  in  living  fetu.ses,  preserving  the  tonus  of 
the  muscles,  it  is  safest  to  follow  up  the  mcmher  to  the  thorax  and  try  to  discover 
the  axilla,  the  rihs,  the  i)ip('-stem-like  clavicle,  and  the  scapula, — even  the  rosary- 
hke  s|)inal  column, — whicii  gives  absolute  information.  In  scapulodextra  po.sterior 
the  axilla  points  to  the  right  behind  (Fig.  552),  the  costal  gridiron  to  the  front,  the 
clavicle  also  to  the  pubis,  the  edge  of  the  scapula  is  behincl,  and  the  arm,  if  down,  is 
the  right  one.  Since  in  very  rare  in.stances  the  upper  arm  i)rolapses,  one  nmst  be 
careful  in  making  diagnoses  on  the  direction  of  the  hand. 

After  labor  has  been  in  progress  for  a  long  time  the  parts  become  so  swollen 
that  diagnosis  is  difficult,  and  if  the  back  or  belly  is  forced  down  into  the  pelvis, 
the  difficulties  encountered  may  be  very  great  and  should  warn  to  unusual  care,

because  even  very  skilful  accoucheurs  have  made  costly  errors.  In  the  difTerential 
diagnosis  breech,  face,  and  vertex  jjresentations.  with  prolapse  of  the  arm.  have  to 
be  considered,  and  confusion  will  be  avoidetl  by  carefully  searching  for  the  landmarks 
pecufiar  to  each. 

Of  great  importance  is  the  diagnosis  of  the  state  of  the  uterus  a.s  regards  the 
imminence  of  rui)ture  and  the  jjresence  of  tetanus,  ami  no  examination  is  complete 
without  thorough  study  of  the  size  of  the  fetus  and  of  the  cavity  of  the  jx-Ivis. 
In  neglected  shoulder  presentations  the  accoucheur  nm.st  discover  if  nature  intends 
to  terminate  the  case  unassisted,  and  if  .so,  which  of  the  three  modes  will  l)o  cho.sen. 
If  these  points  are  properly  evaluated,  the  accoucheur  will  be  able  to  lay  t)Ut  that 
coiu*se  of  ]ir()ce(lure  whicli  will  most  likely  lead  to  a  hap|)y  ending  of  the  ca.s«'. 

Prognosis. — Transverse  presentation  being  always  dystocic  and  retjuiring  the 
intervention  of  art,  the  prognosis  dejiends  on  the  ease  and  safety  with  which  such 
intervention  may  be  made.  If  an  early  diagnosis  is  made,  the  outlook  for  lx)th 
mother  and  babe  is  excellent.  In  neglected  ca.s«»s  the  existence  of  infection,  trauma- 
tism from  ill-directed  interferenc<>.  and  even  of  rupture  of  the  uterus,  indicate  a 
very  grave  situation,  and  to  all  these  must  be  added  the  dangers  of  tlie  inevitable 
operation.     In  a  recent  article  Schultze  shows  that  in  Clennany  alone  fully  400 


624  THE    PATHOLOGY   OF   LABOR 

mothers  and  4000  children  annually  lose  their  lives  in  consequence  of  transverse 
presentation.  For  the  child  the  outlook  is  always  bad  unless  its  precarious  position 
is  recognized  early.  In  neglected  cases  the  infant  almost  always  dies,  from  compres- 
sion of  the  chest,  abruption  of  the  placenta,  or  asphyxia  from  obstructed  placental 
circulation.  Added  to  this  is  the  mortality  attendant  on  the  operations  of  version 
and  extraction  or  even  decapitation  performed  in  the  interests  of  the  mother. 

Treatment, — \'ersion,  not  expectancy,  is  the  treatment  of  transverse  presen- 
tations. The  child  must  be  brought  into  a  longitudinal  presentation — it  must  be 
turned.  During  pregnancy  version  by  posture  is  tried,  and  the  woman  should, 
when  abed,  lie  on  the  side  to  which  the  head  points.  Sometimes  the  breech  will 
sag  over  to  this  side,  forcing  the  head  over  the  inlet.  Examination  at  the  end  of 
three  weeks  may  show  a  longituchnal  presentation,  when  a  binder,  with  pads  on 
each  side,  may  be  applied,  though  success  is  not  constant  The  French  recommend 
a  girdle,  or  "ceinture  eutocique,"  for  this  purpose,  and  the  Japanese  use  daily  massage 
and  kneachng  to  keep  the  fetus  straight.  During  pregnancy  cephalic  version  is 
preferred. 

During  early  labor  version  by  posture  may  be  tried,  but  it  is  better  to  aid 
gravity  by  external  manipulation.  By  gently  leading  the  head  over  the  inlet  and 
pulling  the  breech  up  into  the  fundus  much  may  be  accomplished.  Each  manipu- 
lation is  executed  between  pains,  and  when  the  uterus  contracts,  the  hands  hold 
what  has  been  gained.  An  anesthetic  may  be  advantageous  and  advisable.  Many 
cases  will  be  met  where  the  head  or  breech  has  only  slid  off  into  the  iliac  fossa,  and 
for  these,  external  manipulation  almost  always  suffices.  Wiegand's  method  of 
version  consists  in  placing  one  hand  over  the  breech,  the  other  over  the  head,  and, 
with  alternate  pushing  and  stroking  movements,  striving  to  bring  the  head  down 
over  the  inlet. 

Version  during  early  labor  means  cephalic  version,  but  there  are  three  condi- 
tions which  govern  the  operation:  (1)  There  may  exist  no  immediate  nor  prospec- 
tive indication  for  the  rapid  termination  of  labor;  (2)  the  fetus  must  possess  a  high 
degree  of  mobility,  the  pains  being  weak  and  few,  and  the  bag  of  waters  intact; 
(3)  there  may  not  be  too  great  a  degree  of  pelvic  contraction.  Version  by  external 
manipulation,  thus  governed,  should  be  persisted  in  until  the  second  stage  of  labor 
is  on,  when,  if  it  has  failed,  more  definitive  treatment  is  to  be  instituted. 

The  most  unwelcome  accident  in  shoulder  cases  is  the  rupture  of  the  membranes 
before  the  cervix  is  completely  dilated.  As  has  been  shown,  conditions  are  partic- 
ularly favorable  for  it.  The  accoucheur  seeks  to  avoid  or  delay  the  rupture  of 
the  bag  of  waters  by  keeping  the  patient  on  the  side, — that  one  on  which  the  head 
lay, — by  forbidding  her  to  bear  down  with  the  pains,  and,  best  of  all,  by  placing  a 
Braun  soft-rubber  colpeurynter  in  the  vagina  and  filling  it  nearly  full  of  solution. 
This  exerts  counterpressure  on  the  membranes,  and  also  prevents  the  shoulder  from 
wedging  into  the  pelvis.  After  complete  dilatation  of  the  cervix  has  been  achieved 
a  great  deal  has  been  accomplished,  and  the  question  now  arises,  which  shall  be 
done,  cephalic  or  podalic  version?  Without  doubt  the  child's  chances  are  best  in 
head-first  deliveries,  and  the  attendant  will  do  well  to  consider  the  advisability  of 
cephalic  version,  although  few  authors  recommend  it,  and  it  is  very  rarely  per- 
formed in  practice.  Generally,  the  foot  is  l>rought  down,  with  a  view  to,  with  one 
stroke,  both  correcting  the  malpresentation  and  ol)taining  a  good  purchase  on  the 
child,  so  that  its  delivery  can  be  effected  at  will.  In  the  cases  now  cited  Wright's 
method  of  cephalic  version  would  almost  certainly  lead  to  success,  and  it  is  to  be 
recommended  for  trial.  Should  it  fail  or  prove  too  hazardous,  or  should  the  cord 
prolapse,  as  occurred  once  to  me,  the  attempt  is  to  be  given  up,  and  without  with- 
drawing the  hand  a  foot  grasped  and  podalic  version  performed.  Should  the  first 
attempt  succeed,  the  head  is  to  be  led  into  the  pelvis  or  drawn  down  with  long  for- 
ceps, held  in  proper  position  for  a  few  uterine  contractions,  and  the  case  then  left  to

nature,  or  subject  to  a  new  indication  demanding  extraction.  The  procedure  just 
detailed  would  he  most  dcsirahle  in  primipane,  hut,  unfortunately,  it  is  this  claKs  of 
patients  wliicii  present  the  Ki"t"itest  resistances  to  intra-uterine  mana-uvers,  esix*- 
cially  those  whicii  would  chauf^e  the  location  of  the  fetus. 

Transverse  presentation  ca.ses  seldom  come  for  treatment  un<ler  the  fav<jrai)le 
conditions  thus  far  considered.  Usually  the  hag  of  waters  ha.s  ruptured,  the  os  is 
imperfectly  dilated,  the  shoulder  wedficd  more  or  less  deeply  into  the  pelvis,  and 
the  uterus  retracted  on  tiie  child.  Truly  neglected  ca.ses,  with  tetamis  uteri,  are 
nowatlays,  and  certainly  in  this  city,  exceedingly  rare.  Since  tiie  rupture  of  the 
membranes  lias  deprived  the  uterus  of  its  best  means  of  procuring  sufficient  dilata- 
tion of  the  OS,  nothing  is  more  rational  than  to  try  U)  substitute  the  hag  of  waters. 
This  is  very  successfully  accomplisiied  by  the  colpeuryntcr.  and  this  u'.eful  instru- 
ment shoukl  he  api)lied  in  all  cases  of  shoulder  presentation  where  tin  Inig  oi  waters 
has  ruptured  and  the  cervix  has  not  opened  sufficiently  for  the  introduction  of  the 
hand.  For  such  cases  Hraxtcm  Hicks'  method  of  bipolar  version  (combined  Hianii>- 
ulation  by  two  fingers  inserted  through  the  os,  a.ssisted  by  the  outside  iiand)  has 
been  reconunended.  In  the  autiior's  exjx'rience  the  operation  is  very  difficult  and 
often  impossible  when  the  uterus  has  lost  the  liquor  anmii,  while,  besides,  the  cord 
may  prolapse,  the  placenta  may  be  detached,  or  some  other  indication  arise  for 
immediate  delivery.  This  indication  could  not  be  met  because  the  cervix  is  not 
dilated.  It  is,  therefore,  better  to  ai)ply  a  c(jlpeurynter  inside  the  uterus,  resting 
against  the  cervix.  As  a  rule,  the  pains  now  improve,  becoming  luore  regular  and 
effective;  what  liquid  remained  in  the  uterus  is  prevented  from  escaping,  the 
shoulder  cannot  wedge  itself  further  in  the  pelvis,  and  the  cervix  is  dilated  by  a 
fluid  wedge  much  resembling  tlie  hag  of  waters.  If  10  ounces  of  .solution  are 
injected  into  the  metreurynter,  it  will  measure  about  9  cm.  across,  and  in  j)a.ssing 
through  the  cervix  will  be  compressed  to  about  8  cm.  But  this  sized  opening  is 
sufficiently  large  to  allow  the  hand  to  pass  through,  and  now  version  proper,  with 
the  whole  hand  in  the  uterus,  may  be  performed. 

It  is  dangerous  to  wait  in  these  cases  for  the  pains  to  dilate  the  cervix  f(»r  the 
introduction  of  the  hand,  because  the  labor  will  bt-come  a  "neglected"  one  under 
the  very  eyes  of  the  accoucheur.  If,  on  the  arrival  of  the  attendant,  the  cervix 
will  admit  the  hand,  version  is  inuuediately  performetl,  and,  usually,  by  the  breech. 
Cephalic  version  is  likely  to  be  unsuccessful  in  these  late  ca.ses,  and,  too,  often  an 
indication  for  delivery  coexists  with  that  for  version;  further,  a  slight  degree  of 
pelvic  contraction  may  determine  the  choice  of  method,  and  finally  the  oi)erator 
may  not  have  had  sufficient  experience  with  Wright's  operation.  A  point  of  im- 
mense practical  importance  is  that  after  version  has  been  perfcjrmeil  the  indication 
for  the  operation  has  been  satisfied,  and  the  accoucheur  should  study  the  case 
can^fuUy  to  see  if  anything  in  the  mother  or  the  child  creates  a  new  indication  for 
the  extraction  of  the  child.  In  other  words,  the  operations  of  version  an<l  extrac- 
tion must  be  separatetl,  unless,  at  the  same  time,  intlications  exist  for  l>oth.  Since 
the  operation  of  version,  by  .s(>parating  the  placenta  or  causing  entanglement  of 
the  cord,  may  create  an  indication  for  delivery,  it  is  advisable  to  begin  tlu'  version 
only  after  complete  dilatation  of  the  cervix  has  l)een  j)rocured. 

Neglected  shoulder  presentations,  especially  those  where  one  of  the  mmh-s  (»f 
spontaneous  expulsion  is  in  progress,  present  truly  intricate  .situations  for  the 
accoucheur  to  solve.  Th(>  tetanically  contracted  uterus  may  foil  every  attempt 
at  version,  even  in  ])rofound  anesthesia,  and  to  force  it  would  inevitably  <-au.«i<'  a 
rupture*  of  the  organ.  The  stretched  vagina,  tightly  hlled  with  the  large  bulk  of 
the  presenting  jmrt.may  not  permit  the  fingers  to  gain  access  to  the  uterine  cavity.

consideration  need  be  given  to  the  child  in  this  class  of  cases  because  it  almost 
invariably  has  long  succumbed.  Decapitation  and  exenteration  are  the  operations 
of  choice.  If  the  neck  is  ^^^thin  easy  reach,  decapitation  by  means  of  Carl  Braun's 
hook  may  be  done,  but  the  author  prefers  the  operation  of  exenteration.  Even  the 
most  skilful  accoucheur,  in  performing  a  decapitation,  will  twist  the  head  against 
the  thinned  lower  uterine  segment  and  precipitate  its  rupture,  while  bj^  exenterating 
the  fetus  it  can  be  delivered  ^nthout  sul^jecting  the  uterus  to  any  additional  strain. 
If  the  chest  of  the  child  is  wedged  deeply  into  the  pelvis,  the  accoucheur  ^^^ll  find 
the  neck  stretched  up  above  the  inlet  on  one  side,  and  the  spinal  column  on  the 
other,  but  almost  parallel  to  the  axis  of  the  pelvis,  and,  of  course,  not  placed  so  that 
a  hook  introduced  from  the  vagina  could  operate  at  a  right  angle  to  them.  Here 
exenteration  is  the  operation  of  necessity.  Should  the  accoucheur  observe  that 
nature  is  terminating  the  case  in  one  of  the  three  modes  described,  he  may,  though 
it  is  contrary  to  most  teachings,  exert  tentative  traction  on  that  part  of  the  fetus 
which  seems  to  advance  most,  or  at  least  seek  to  aid  that  mechanism  which  is 
occurring  under  his  eyes. 

Prolapse  of  the  arm  is  not  a  complication  of  shoulder  presentation.  It  does 
not  interfere  ^^'ith  any  treatment.  It  is  wise  to  put  a  sling  on  the  WTist,  and  lay 
the  end,  sterile,  over  one  groin.  The  arm  need  not  be  replaced  in  the  uterus,  nor 
should  it  be  amputated  under  any  circumstances.  A  physician  amputated  both 
arms  of  a  presumably  dead  child  and  delivered  it  later  alive! 

What  shall  be  done  in  neglected  transverse  presentations  when  version  is 
impossible  or  too  hazardous  and  the  child  still  alive?  From  the  nature  of  the  case, 
cesarean  section  is  contraindicated,  because  it  jeopardizes  the  mother  too  much, 
and  the  child,  though  living  at  the  time  of  delivery,  in  the  majority  of  cases  dies 
soon  after  from  the  effects  of  the  compression.  In  the  author's  opinion,  embryot- 
omy should  be  done.  While  it  sacrifices  what  little  life  the  child  has  and  is  a  pain- 
ful task  for  the  accoucheur,  it  offers  the  mother  the  greatest  safety. 

Preceding  all  operations  in  shoulder  deliveries  a  painstaking  examination  is 
to  be  made  to  discover  the  existence  of  a  complication  which  might  affect  the 
treatment,  as  contracted  pelvis,  placenta  praevia,  or  nephritis,  and,  after  delivery, 
the  uterus  and  vagina  must  be  explored  to  determine  the  integrity  of  the  parturient 
canal — advice  which  cannot  be  too  frequently  reiterated. 


PROLAPSE  OF  THE  CORD 

This  error  of  attitude  occurs  once  in  about  400  cases,  and  has  been  observed  as 
early  as  the  fourth  month  of  pregnancy.  During  labor  it  is  most  unwelcome, 
because  the  life  of  the  child  is  so  intimately  concerned.  Three  degrees  of  prolapse 
of  the  cord  ma}^  be  distinguished:  (1)  An  occult  form,  where  the  cord  is  at  or  near 
the  girdle  of  resistance,  but  not  within  reach  of  the  fingers  during  the  ordinarily 
careful  examination.  Here  the  condition  is  not  suspected,  and  the  child  may  die 
from  compression  of  the  cord  in  natural  delivery  or  by  the  blade  of  the  forceps 
(Fig.  553).  (2)  The  cord  may  be  forelying,  that  is,  palpal^le  through  the  os,  but  in 
the  intact  bag  of  waters  (Fig.  554) .  (3)  The  cord  may  be  prolapsed  into  the  vagina 
or  even  outside  of  the  vulva,  the  bag  of  waters  being  ruptured  (Fig.  555). 

Etiology. — Anything  which  causes  a  maladaptation  of  the  presenting  part  to 
the  lower  uterine  segment  or  prevents  engagement  of  the  head  ■\\ill  favor  prolapse 
of  the  cord.  In  normal  presentations  the  lower  uterine  segment  is  so  evenly 
applied  to  the  head  that  there  is  no  room  for  the  cord  to  slip  down.  jMechanical 
causes  are:  (1)  Contracted  pelvis,  the  head  being  arrested  high  and  free  spaces 
being  left  at  the  sides;  indeed,  the  discovery  of  the  cord  must  evoke  the  suspicion 
of  a  contracted  pelvis.  In  Hildebrand's  126  cases  of  prolapsed  cord  one-third 
had  contracted  pelvis;    (2)  malpositions  and  malpresentations;    occipitoposterior,

face  and  brow,  breech  and  shoulder  presentations;  (3)  low  attachment  of  the 
placenta,  with  marginal  insertion  of  the  cord;  (4)  pret.-niaturally  Ioiik  c<ml,  though 
a  short  one  may  alscj  prohipse;  (5)  displaeenient  of  t  lie  eon!  as  an  <'rrur  of  art  during 
obstetric  operations;  ((i)  prolapse  of  an  arm.  Other  causes  are  twins,  i>olyhy<lram- 
nion,  the  cord  being  rushed  out  witli  the  bursting  of  the  membranes,  and  esi"xMially 
since  the  head  is  usually  high  in  such  cases;  the  accidental  floating  out  of  the  c«ird 
when  the  waters  break  before  the  head  is  engaged,  as  occurs  in  multipara-  other- 
wise normal.  It  has  occurred  to  the  author  that  ix-rhaps  the  specific  gravity  of 
the  licjuor  aninii  may  have  .something  to  do  with  the  prolap-se. 

Course  and  Prognosis.— So  far  as  the  mother  ia  concerned,  i)rolapse  of  the 


Fig.  .">.j,3. — (><-cfi.T  PRoi_\pnr.  or  the  Cord.

cord  does  not  affect  the  course  of  labor,  except  inasmuch  as  the  cau.se  of  the  prolajise 
might  do  so,  and  she  is  not  (ndangered  except  by  these  caus<'s,  and  by  the  op«'ra- 
tions  which  might  be  undertaken  on  account  of  them,  and  to  save  the  life  of  the 
child. 

For  the  child  there  is  great  danger,  since  the  soft  bltHMl-vess<'ls  easily  suffer 
compression  and  asphyxia  results.  The  cord  is  most  easily  compress4tl  in  head 
presentations  when  it  lies  in  front,  behind  the  pubis.  When  it  has  slii)iK'd  down 
at  the  side,  near  the  sacro-iliac  joints,  it  hnds  some  little  protection  Ix-hintl  the 
jutting  promontory,  though  the  soft  parts  alone  can  exert  fatal  ctunpression. 
Compression  of  the  cord  affects  the  vein  first,  reducing  tin*  amount  of  bl«MKl  going 
to  the  fetal  heart,  and  causing  placental  congestion.     As  the  result  of  the  anemia 


628 


THE    PATHOLOGY    OF   LABOR 


and  the  asphyxia  the  fetal  heart  slows,  sometimes  to  50  or  60,  during  the  contraction 
of  the  uterus,  and,  when  the  compression  is  relieved,  tlie  heart  l)ounds  up  to  130 
to  160  a  minute.  But  this  does  not  mean  that  the  circulation  has  recovered,  because 
in  many  instances  minute  hemorrhages  in  the  lungs  and  even  heart-clot  have  been 
produced,  which  render  extra-uterine  existence  impossible.  If  the  cord  hangs  out 
of  the  vulva,  it  may  congeal  from  cold  or  the  mother  may  lie  on  it.  In  breech  and 
shoulder  presentation  the  danger  of  comjiression  is  not  so  acute,  though  still  serious, 
and  if  an  ex^tremity  has  also  prolapsed,  the  cord  may  find  protection  by  lying 
alongside  and  parallel  with  it.  An  additional  danger* to  the  child  will  arise  in  the 
operations  undertaken  for  its  rescue — all  of  which  explains  the  40  to  50  per  cent, 
mortality  in  operated  cases  and  the  80  per  cent,  in  those  left  to  nature.

This  cord  may  be  compressed. 


Diagnosis. — Occult  prolapse  of  the  cord  should  be  thought  of  when,  in  an  other- 
wise natural  labor,  the  fetal  heart-tones  are  irregular  or  arhythmic,  and  when,  as  in 
the  forceps  operation,  auscultation  reveals  cardiac  tumult  during  the  tractions.  A 
persistent  funic  souffle  with  irregularity  of  the  heart  is  very  significant.  Ausculta- 
tion of  the  fetal  heart  is  an  indispensable  routine  in  the  conduct  of  labor.  By  deep 
insertion  of  the  fingers  behind  the  pul)is  it  is  often  possible  to  discover  the  knuckle 
of  cord  as  it  lies — usually  above  one  ear — alongside  the  head.  (See  Forceps.) 
A  forelying  cord  in  the  intact  hag  of  waters  will  escape  only  the  careless  diagnosti- 
cian, and  it  will  also  be  easy  to  differentiate  it  from  velamentous  umbilical  vessels, 
from  pulsating  arteries  in  the  fornices,  and  from  polyps. 

After  rupture  of  the  bag  of  waters  no  difficulty  is  experienced — it  is  often

Treatment. — As  has  been  stated  on  similar  (x-casions  many  times,  all  treatment 
mu.st  be  preceded  by  a  careful  obstetric  examination,  including  jx'lvic  mensuratii)n, 
to  discover  tiie  cause  of  the  prolapse,  and  all  adjuvant  factors  which  may  alter 
and  direct  the  course  of  procedure  demanded  by  the  indications.  For  example,  a 
contracted  pelvis  may  indicate  cesarean  .s*'ction,  <tr  a  low-lying  placenta  Braxton

the  vagina.  All  preparations  are  made  for  quick  operative  delivery,  and  the  ac- 
coucheur stays  by  the  bedside.  When  complete  dilatation  of  the  cervix  has  been 
obtained,  nine-tenths  of  the  danger  has  been  obviated.

Note  concavity  above  pubis  caused  by  the  head  leaving  the  inlet. 

When  Prolapse  has  Occurred. — First,  if  the  cord  is  outside  the  vulva,  it  must 
be  sterilized  and  replaced  within  the  vagina.  Now  one  of  two  things  must  be  ac- 
complished: either  the  child  must  be  delivered  or  the  cord  must  be  put  in  a  place 
where  it  will  not  be  compressed.  Naturally,  if  conditions  are  right  for  immediate 
extraction,  this  is  the  most  advisable  procedure,  because  it  instantly  extricates  the

child  from  its  precarious  position.  For  rapid  extraction  the  cervix  nmst  be  effaced 
and  completely  dilated,  conditions  which  are  seldom  present.  Everything  depends 
on  the  cervix. 

(a)  If  the  cervix  is  not  open  enough  to  admit  the  hand,  the  accoucheur  must 
relieve  the  cord  from  the  danger  of  compression.  Braxton  Hicks'  version  has  been 
proposed,  but  the  operation  is  difficult;    often  the  cord  does  not  recede  with  the 


ANOMALIES    OF   THE    PASSENGERS 


631 


change  of  polarity  of  tlic  Ixjdy,  and,  further,  the  chances  of  the  child  are  not  much 
improved  by  the  operation,  since  extraction  may  not  he  done  at  once,  and  during  the 
long  wait  for  complete  dilatation  the  child  usually  dies. 

It  is  better  to  replace  the  cord  above  the  iiead  and  put  a  metreurynt<'r  in  the 
cervix,  to  prevent  its  falling  down  again.  II.  M.  Stow<'  advi.sed  to  fill  the  uterus 
with  .salt  solution  after  replacing  the  cord,  and  invented  a  metreurynter  for  this 
purpo.se.  Replacement  of  the  cord  may  be  accomplished  with  a  catheter  and  stilet, 
as  shown  in  Fig.  ooO,  (/  and  h,  the  catheter  being  left  in  placo  until  complete  dila- 
tation has  been  ()l)tained,  or  the  two  fingers  may  l)e  employed  to  push  the  cord  uj). 
All  these  nuuKcuvers  are  carried  out  with  the  woman  in  the  knee-chest  jjosture,  in 
order  to  get  the  benefit  of  gravity,  and,  before  the  hand  is  withdrawn,  a  metreur- 
ynter is  in.serted  in  the  lower  uterine  segment  and  filled  with  12  ounces  of  weak 
anti.septic  solution,  or  the  cervix  is  packed  with  gauz( — this  precaution  to  hinder 
the  cord  from  falling  out  again  and  to  keep  the  head  away  from  the  inlet.  After 
the  cervix  is  thus  thorouglily  plugged,  the  woman  may  be  placed  on  her  back  or 
side.  Neither  of  these  methods  is  uniformly  successful.  The  repositor  may  kink 
or  injure  the  cord  or  woimd  the  uterus,  and  the  fingers  may  not  be  able  to  push  the 
loops  above  the  globe  of  the  head,  and  in  both  instances  the  cord  is  likely  to  pro- 


FiG.  ojS. — KxEF.-riiKsT  Position. 


lapse  again  as  soon  as  the  woman  is  laid  on  the  back  or  when  the  colpeurynter  comes 
out.  Then,  too,  the  cord  may  not  be  relieved  of  compression  by  the  operation,  and 
even  the  bag  may  press  on  it.  In  one  case  where  the  cord  could  not  be  replaced  I 
jMilled  the  arm  down  alongside  the  head  and  tucked  the  cord  beside  it.  thus  pn*- 
tt'cting  it  from  injury.     A  thick  rectal  bougie  might  be  u.sed  for  this  purp«)se. 

(b)  If  the  cervix  will  atlmit  the  hand,  there  are  two  methods  to  choose — version 
and  reposition  of  the  cord.  Equally  good  results  are  obtained  from  both  oix-ra- 
tions;  the  choice,  therefore,  will  depend  on  individual  skill  and  preference,  plus 
the  conditions  pn^sented  by  each  case.  \'ersion  will  be  selected  when-  (1)  Other 
indications  for  version  are  present;  (2)  when  a  contracted  pelvis  of  minor  degree 
coexists;  (3)  in  face,  brow,  or  other  abnormal  presentation;  (4)  when  an  indication 
for  delivery  on  the  part  of  the  mother  or  child  arises  or  is  to  In*  anticipated;  (5) 
when  reposition  has  failed  or  the  cord  fallen  down  again. 

It  is  always  desirable  to  secure  coniplete  dilatation  before  turning,  because  it 
may  be  necessary  to  t\)llow  the  version  with  the  acces.'^ory  operation  of  extraction. 

Reposition  is  practised  as  follows:  If  the  woman  will  pi'rmit  the  oixTation 
without  an  anesthetic,  the  knee-chest  posture  is  employed;  if  not.  the  exaggt>ratod 
Trendelinburg  is  used.     Pa.-^sing  the  whole    hand    into    tiie    vagina,  the   corti    is

THE    PATHOLOGY    OF   LABOR 


allowed  to  coil  in  the  palm,  which  is  hollowed  out  for  its  reception,  the  fingers  making 
a  sort  of  cage  for  it  (Fig.  560).  Then,  pushing  the  head  up  and  to  one  side,  going 
in  the  direction  indicated  by  the  cord  itself,  the  loops  are  quickly  carried  to  the 
highest  point  attainable  in  the  uterus,  and,  if  possil)le,  the  cord  is  hung  over  one  leg. 
While  doing  this  the  other  hand  puslies  the  head  away  from  the  inlet.  After  the 
cord  is  replaced,  the  inside  hand,  acting  with  the  outside  hand,  brings  the  head  over 
the  inlet,  and  a  few  pains  are  awaited  to  force  it  down.  It  may  be  advisable  to  pull 
the  head  into  the  pelvis  with  forceps  and  then  leave  the  case  to  nature.  By  keep- 
ing the  woman  on  the  side  the  cord  is  prevented  from  coming  down  again. 

Reposition  is  not  likely  to  be  successful  nor  advisable  when  the  pelvis  is  con-

tracted,  and  it  is  usually  not  practised  in  the  presence  of  an  indication  for  innnediate 
extraction.  When  the  child  is  in  bad  condition,  both  reposition  and  version  are 
usually  powerless  to  save  it,  but  in  these  cases  the  author  prefers  reposition  for 
primiparifi  and  version  for  multiparae. 

In  all  cases,  after  Braxton  Hicks'  version,  after  version  and  after  replacement, 
the  heart-tones  of  the  fetus  must  be  continuously  observed,  in  order  to  detect  the  first 
signs  of  a  threatening  asphyxia.  Even  after  apparent  successful  replacement  the 
cord  may  be  compressed  at  a  point  not  suspected. 

When  the  head  is  engaged,  reposition  and  vei-sion  are  usually  impossible,  and 
the  safety  of  the  child  lies  in  its  quick  delivery.     If  the  cervix  is  fully  opened,  no

difficult  ics  arc  met ;  if  it  is  not,  manual  dilatalioii,  Diihrssen's  incisions,  even  vaginal 
cesarean  section,  may  he  emphAcd,  and  tlien  forceps  applied.  Which  method 
will  be  selected  depends  on  tiic  condition  of  the  cervix  as  regards  efTacement  and 
dilatation  and  the  acconii)lishments  of  the  accoucheur. 

If,  when  called  to  the  case,  the  cord  is  found  pulsating  feebly  or  not  at  all,  the 
accoucheur's  first  duty  is  to  determine,  so  far  as  possible,  the  actual  condition  of 
the  child  and  its  chances  for  ultimate  recovery  even  if  delivered  alive.  It  is  no  feat 
to  be  proud  of  to  deliver  a  child  at  the  expense  of  extensiv<'  maternal  injuries  when 
it  dies  after  a  few  minutes  or  hours  from  late  asphvxia  or  cerebral  hemorrhage. 
If  a  prolapse  of  the  cord  finds  the  accoucheur  unprepared  for  its  prf»per  treatment, 


Fio.  500. — Replacement  of  Prolapsed  Coku  with   Whole  H.\.\d.     Patie.nt  in   Knee-chest  Postcbe. 


the  heati  may  be  held  back  and  the  cord   jirotected  l>y  the  hand  inside  until  as- 
sistance can  be  procured. 

When  the  infant  is  dead,  the  case  is  to  be  left  to  nature,  but  if  an  indication  for 
delivery  on  the  ])art  of  the  mother  arises,  craniotomy  is  the  operation  of  choice. 
In  a  primipara  craniotomy  on  the  dead  child  should  l)e  recommended  to  save  the 
perineal  floor  from  the  overdistention.  Forceps  and  version  on  a  deatl  child  are 
contraindicatcd.  Of  course,  if  there  is  douijt  of  the  life  of  the  child,  it  should  have 
the  l)(>nefit  of  the  doubt.  What  to  do  when  t!ie  cord  is  pulsating  only  feebly  and 
there  is  reason  to  believe  the  death  of  the  child  is  not  far  distant  is  not  easy  to  decide. 
If  the  child  can  be  cpiicklN  brought  to  light  without  the  danger  of  serious  maternal

injury,  it  ought  to  get  this  chance  for  its  life,  Init  if  the  operative  delivery  promises 
to  be  hard — a  priniipara,  for  example — or  tedious,  it  is  more  than  likely  that  the 
child  will  perish  during  the  attempt  to  save  it,  or  shortly  afterward.  The  almost 
inevitable  cervical  and  perineal  lacerations  will  then  make  the  accoucheur  regret 
his  futile  and  perilous  effort.

presentations  carries  a  degree  of  danger  slightly  less  tlian  with  head  presentations. 
j\Iost  authors  say  that  the  cord  is  not  easily  compressed  ])y  the  soft  breech,  but  this 
is  not  my  experience.  It  is  best  to  replace  the  cord,  hanging  it  over  the  shoulder, 
and  then  put  in  a  metreurynter. 

With  transverse  presentation  prolapse  of  the  cord  requires  no  special  treat- 
ment. During  the  preparations  for  version  the  cord  is  to  be  kept  clean  and  warm 
by  putting  it  into  the  vagina  and  applying  a  vulvar  plug.  If  the  cervix  is  to  be 
dilated  by  a  metreur>Titer,  the  cord  is  first  pushed  up  into  the  uterus. 

Cesarean  section  has  been  proposed  for  the  treatment  of  prolapsed  cord.  At 
first  breath  it  would  seem  that  such  an  operation  would  never  come  up  for  con- 
sideration, since  it  is  done  almost  entirely  in  the  interests  of  the  child,  but  the  author 
can  think  of  several  conditions  in  which  the  abdominal  delivery  would  command 
serious  attention.  These  are:  (1)  An  aged  primipara,  very  desirous  of  a  child. 
Here,  if  the  parturient  canal  is  unprepared,  the  child  is  almost  invariably  lost; 
(2)  mild  degrees  of  pelvic  contraction,  insufficient  of  themselves  to  indicate  cesarean 
section;  (3)  wiiere  the  religious  scruples  of  the  family  demand  that  in  all  operations 
the  child  be  given  equal  chances  with  the  mother.  Couvelaire  and  Potocki  report 
successful  cases.  When  cesarean  section  is  considered  in  the  treatment  of  prolapsed 
cord,  two  conditions  must  be  insisted  upon:  the  child  must  be  in  perfect  condition 
and  the  mother  have  not  even  the  suspicion  of  infection. 


PROLAPSE  OF  THE  ARMS  AND  FEET  WITH  THE  HEAD 

In  general,  the  same  causes  which  produce  prolapse  of  the  cord  may  permit  the 
hands  or  feet  to  come  down  alongside  the  head.  Voluntary  motions  of  the  child 
may  also  be  mentioned.  On  several  occasions  the  author  has  felt  the  child  present 
a  hand  at  the  os  and  then  withdraw  it.  If  the  bag  of  waters  should  break  at  this 
moment,  the  extremity  would  be  floated  out.  Contracted  pelvis,  small  or  dead 
fetus  (lack  of  tonicity),  and  sudden  rush  of  liquor  amnii  are  the  usual  causes.  The 
complication  occurs  once  in  about  250  labors.  We  speak  of  the  presenting  or  fore- 
lying  hand  or  foot  when  the  extremity  is  felt  in  the  intact  sac  at  the  os,  and  of 
prolapse  when  the  membranes  are  broken  and  the  part  is  in  the  vagina. 

Prolapse  of  the  arm  may  influence  the  mechanism  of  labor.  In  the  first  place, 
it  may  stiffen  the  fetal  cylinder  and  confer  a  rigidity  which  is  harmful  to  normal 
rotation,  and,  secondly,  by  prolapsing  in  a  portion  of  the  pelvis  which  the  occiput 
should  traverse,  it  may  prevent  anterior  rotation  of  the  same.  For  example,  if  in 
O.L.A.  the  posterior  arm  prolapses  alongside  the  forehead,  it  will  aid  anterior  rota- 
tion; if  the  anterior  one  comes  down  behind  the  pubis,  it  will  delay  or  prevent  it. 
An  arm  lying  in  the  anterior  half  of  the  pelvis  will  obstruct  labor  more  than  if  in 
the  hollow  of  the  sacrum,  where  there  is  more  room.  The  anterior  arm  is  the  one 
usually  found,  and  prolapse  occurs  oftener  with  occipitoposterior  positions.  The 
diagnosis  is  simple,  but  the  accoucheur  should  always  remember  that  the  hand  may 
be  that  of  a  shoulder  presentation  or  of  a  second  twin,  and  that  sometimes  the  foot 
may  be  mistaken  for  the  hand. 

Treatment. — Before  rupture  of  the  bag  of  waters,  while  the  head  is  still  above 
the  inlet,  posture  will  usually  suffice.  Place  the  woman  on  the  side  on  which  the 
hand  tloes  not  lie.  As  labor  advances  the  head  pushes  by  the  arm.  After  the 
membranes  rupture,  as  a  rule,  the  head  enters  the  pelvis,  the  arm  being  held  back,

but  sometimes  the  arm  {jrcvcnts  the  ongap;ement  of  the  head.  Here  the  extremity 
must  he  replaced,  using  tiie  half  or  the  whole  hand,  under  anesthesia,  if  necessary, 
If  this  fails,  or  if  the  arm  falls  down  again,  version  is  perfcjrmed.  \'ersion  is  also 
done  when,  in  addition  to  the  arm,  the  cord  is  down  or  the  placenta  is  l(jw  in  the 
Uterus,  or  any  other  indication  for  changinu  tlie  polarity  of  the  fetus  exists. 

After  the  head  lias  engaged  with  the  arm  nothing  is  dcjne  hecau.se  there  is 
evidently  enough  room  in  the  pelvis  for  the  two.  Since  labor  is  longer  and  anom- 
alies of  rotation  commoner,  ftjrceps  are  more  often  needed.  In  ai)plying  the  for- 
ceps care  to  see  that  the  blades  do  not  grasp  the  arm  is  necessary.

a  distended  che.st  was  the 
cause  of  the  obstruction, 
that  the  real  reason  was 
discovered.  With  consider- 
able difficulty  the  arms  were 
gotten  into  projM>r  position 
and  then  the  instrumental 
tlelivery  was  easily  com- 
pleted. Unless  such  re- 
placement of  the  arms  is 
jjo.ssible,   the    case  will   be 

formidable.  Version  was  successful  in  Simpson's,  CIray's,  and  Lambert's  ca.<5es.

or  drawn  down. 

Prolapse  of  the  foot  alongside  the  head  is  very  rare,  and  only  four  such  cases 
occurred  in  the  author's  exi)erience.  \'ersion  in  each  instance  was  ea.*<y,  though 
most  authors  say  it  is  difficult  under  the  circum.stances.  Since  the  fetal  cylinder 
is  made  rigid,  slow  advance  and  delayecl  rotation  are  usual,  and.  therefore,  forceps 
oftener  needed.  If  the  foot  i)revents  engagement  of  tin'  head,  it  may  be  ])ushed 
away  and  the  head  led  into  the  pelvis  by  combined  numipulation;  if  this  dtH's  not 
succeed,  version  is  the  treatment.  If  the  foot  and  head  hav«'  engaged  in  tlu-  pelvis, 
watchful  expectancy  anil  forceps,  if  needed,  are  recommendeil.

CHAPTER  LI 

ANOMALIES  OF  THE  PASSENGERS  (Concluded) 

DYSTOCIA  DUE  TO  EXCESSIVELY  LARGE  FETUS 

Older  writers  report  the  birth  of  children  weighing  23  and  24  pounds  (Ortega, 
Rachel,  and  Xeumer,  quoted  by  Dubois  in  1897).  Beach  reported  a  giantess'  child 
weighing  10,773  gm.,  about  221^2  pounds,  and  being  76  cm.  long.  It  is  best  to  ac- 
cept the  stories  related  by  patients  as  to  the  immense  size  of  their  previous  children 
with  much  reserve,  because  they  are  usually  exaggerated  or  mere  guesses.  The 
largest  child  delivered  by  the  author  weighed  14  pounds  and  necessitated  cesarean 
section.  It  Avas  diseased  and  died  with  high  fever  in  sixteen  hours.  Another, 
weighing  123^  pounds,  was  delivered  by  forceps  and  survived.  In  the  service  of 
the  Chicago  Lying-in  Hospital  and  Dispensary,  in  over  15,000  cases,  only  3  children 
weighed  more  than  12  pounds,  and  in  2264  hospital  cases  only  2  weighed  over  11 
pounds,  5000  gm.     All  these  children  gave  rise  to  marked  dystocia. 

Given  a  normal  pelvis,  normal  powers,  and  a  normal  presentation,  position, 
and  attitude,  nature  is  usually  capable  of  accomplishing  the  delivery  of  children 
weighing  up  to  9  pounds  "without  very  great  difficulty. 

Etiology. — (1)  Partus  serotinus,  prolonged  pregnane}',  carrying  overterm,  has 
been  recognized  as  a  cause  of  overdevelopment  of  the  child,  and  was  recently 
statistically  proved  by  von  Winckel.  In  addition,  my  own  studies  show  that  the 
bones  become  harder,  less  malleable,  the  spine  stiffer,  the  fat  and  muscles  firmer,  and 
the  head  actually  larger  and  more  square  in  shape,  with  pointed  parietal  bosses. 
The  fontanels  are  smaller,  the  sutures  almost  closed  and  in  apposition.  Sometimes 
children  carried  overterm  are  lighter  in  weight  compared  to  their  increased  length, 
but  the  difficulties  of  delivery,  rather  than  being  diminished  by  the  long  narrow  fetal 
cylinder,  are  really  augmented,  because  of  the  lack  of  moldability.  (2)  Overeating 
in  pregnancy  is  not  a  common  cause  of  overdevelopment  of  the  fetus,  but  experience 
shows  that  women  of  the  better  situated  classes  and  those  of  indolent  habit  have 
larger  babies  than  those  that  have  to  work  hard  and  are  poorly-  fed  in  pregnancy. 
In  France  and  Germany  special  provision  is  made  for  these  women  with  a  view  to 
improving  the  offspring.  (3)  Multiparity — children  of  later  pregnancies  are  usu- 
ally larger  than  that  of  the  first,  but  an  exception  is  to  be  noted  in  old  primiparse 
with  male  children.  These  are  likely  to  be  large  and  a  frequent  cause  of  dystocia. 
(4)  Large  parents  usually  have  large  children,  which  is  fortunate  only  if  the  mother 
exceeds  the  normal  size,  because  then  her  pelvis  Avill  accommodate  the  child.  A 
large  father  may  procreate  children  which  the  mother  cannot  deliver.  In  one  of 
the  author's  consultations  the  third  wife  of  a  very  large  and  powerful  man  died,  as 
did  the  other  two,  from  obstructed  labor.  (5)  Finally,  no  particular  cause  being 
found,  it  is  supposed  that  some  factor  producing  a  large  ovum  may  be  the  reason 
for  the  overgroAvlh  of  the  fetus.  Since  the  children  in  placenta  prajvia,  placenta 
circumvallata,  and  other  placental  anomalies  are  usually  small,  exceptional  condi- 
tions of  nutrition  may  produce  very  large  children. 

Course. — During  ])regnancy,  overdistention  of  the  bell}^  may  cause  the  same 
disturbancesastwins  (whichareusually  suspected) ;  these  are,  a  feeling  of  great  weight, 
dyspnea,  edema,  albuminuria,  pendulous  belly,  etc.  If  labor  is  postponed,  inter- 
mittent false  pains  may  annoy  the  woman  for  several  weeks.  Labor  is  slow,  and 
usually  characterized  by  weak  pains  (from  overdistention),  with  early  rupture  of

tho  membranps,  Ix'cuusc  the  head  onKaK<'s  late  Cephalic  prosontations  an*  tho 
rule.  ( )(Tipit()p()st('ri(>r  positions  are  very  conunon.  In  gcnrral,  tlir  course  of 
labor  resembles  that  in  contracted  pelvis  of  the  justominor  tyiw.  If  the  head  is 
not  too  hard,  it  molds  into  the  pelvis  and  is  delivered  under  strong  l)earing-<lo\vn 
effort  or  by  the  aid  of  art.  The  broad  shoulders  then  cause  delay,  (iirls  have 
broader  shoulders  than  l)oys  when  compared  with  the  size  of  the  head.  Aft<'r  the 
head  is  out,  it  snaps  back  against  the  i)erineum,  pressing  this  upward  into  the  jM-lvis, 
due  to  the  ela.sticity  of  the  fetal  neck.  Unless  the  .shouhlers  can  be  brought  down, 
the  child  quickly  dies.  Anomahjus  mechanisms  are  very  common,  but  delay  in 
engagement  of  tiie  shoulder-girdle  is  the  usual  cau.se  of  the  tnjuble,  an<l  this  is  U'- 
cause  it  is  too  large  or  inc(impre.ssible.  Kupture  of  the  uterus  may  occur  in  the 
dystocia  due  to  the  delivery  of  voluminous  shoulders.  Even  the  breech  may  Ix'  so 
voluminous  that  its  delivery  is  slow. 

Po.stpartum  hemorrhage  and  anomalies  of  placental  separation  are  more  fre- 
c|Uent  than  usual,  because  the  large  uterus  needs  time  to  retract  on  itself  and  may 
not  do  so  i)erfectly.  Lacerations  must  al.so  be  expected,  especially  if  any  manipula- 
tions were  recjuircd. 

Diagnosis. — A  very  large,  i)rotul>erant  l)elly  will  excite  the  suspicion  of  an 
overgrown  child,  of  twins,  or  of  hydranmion.  Absence  of  fluctuation  will  exclude 
the  latti-r,  and  the  recognized  methods  will  usually  suffice  to  discover  two  fetu.ses. 
( 'cphalometry  iq.  v.)  is  giving  better  results  since  it  is  being  practised  more.  If 
the  accoucheur  will,  in  every  case,  endeavor  to  determine  accurately  the  size  of  the 
chikl  before  the  birth,  and  control  his  findings  by  later  measurements,  he  will  ac- 
(juire  a  degree  of  accuracy  in  estimating  the  size  of  the  fetus  which  he  would  not 
have  believed  possil)le.  The  size  of  the  fetus  is  just  as  inii)ortant  a  matter  for  the 
oijstetrician  to  know  as  the  size  of  the  pelvis.  Of  nearly  ecjual  moment  is  the  hard- 
ness of  the  fetal  head.  This  is  determinable  by  bimanual  palpation,  from  the  size 
of  the  fontanels,  and  by  noting  how  well  the  bones  of  the  head  overlaj)  as  the  latter 
enters  the  pelvis  under  the  intiuence  of  the  pains.  After  di-livery  of  the  head  a 
stoppage  of  labor  usually  results  from  the  big  trunk,  but  the  po.ssil)ility  of  anomalous 
mechanisms  of  the  shoulders  and  of  tumors  of  tlie  fetal  body,  or  ilorsal  displacement 
of  the  arms,  must  be  remembered.  In  a  breech  presentation  the  size  of  the  part 
will  give  a  good  indication,  and  especially  if  the  foot  is  down.  A  large  leg  and  foot 
usually  means  a  large  child. 

Prognosis.^For  the  mother,  it  depends  on  the  degree  of  tlisproportion  between 
the  child  and  tiie  pelvis,  and  if  this  is  very  great  antl  goes  unrecognized,  the  motlier 
may  die — of  ruptured  uterus,  sepsis,  exhaustion,  or  inHicted  injuries.  Ordinarily, 
however,  the  mother  may  be  successfully  delivered  if  the  child  weighs  not  over  o()(M) 
gm.  (11  pounds)  and  otiier  conditions  are  favorable.  The  delivery  of  an  i-nornmus 
diild  through  a  normal  pelvis  is  harder  than  the  delivery  of  a  normal  chiUl  through 
a  contracted  pelvis,  even  when  the  proj^ortions  are  the  same.  For  the  child,  the 
prognosis  is  not  so  good.  Many  more  die  in  lal)or,  from  asphyxia,  com|)ression  of 
tlie  brain,  and  from  the  injuries  inflicted  in  operative  delivery.  Intracranial  hemor- 
rhage, fissure-fractures  of  the  skull,  cephalhematomata,  spoon-shajMHl  depressions, 
Erb's  paralysis — all  are  more  frequent.  It  must  be  rememln'reil  that  sometijues 
these  large  children  are  diseased — for  example,  suffering  from  an:isiirca,  universal 
hydrops,  or  myxedema.  After  ilelivery  the  large  children  lo.se  more  in  weight, 
even  prnportionately. 

Treatment. — As  was  already  said,  the  author  considers  it  unwise  to  allow  women 
to  go  far  overterm,  and  when,  after  careful  consiileration  of  all  obtainable  infonna- 
tion,  subjective  and  olijective,  he  decides  that  the  usual  ihtIimI  of  gj'station  has 
l)een  completed,  he  induces  labor.  (See  Prolonged  Pregnancy.)  This  procedure 
is  still  more  necessary,  and  may  lie  doni*  several  weeks  liefore  term,  when  the  woman 
gives  a  history  of  large  children  and  dilficult  lal)ors.     Prochownik  instituted  a  special 


638  THE    PATHOLOGY    OF    LABOR 

dietary  for  such  cases,  hoping  thus  to  diminish  the  size  of  the  child,  but  in  my  cases 
it  was  not  successful,  which  failure  other  authors  also  admit  (Ballantync). 

During  labor  the  important  thing  is  to  discover  early  that  the  infant  is  large, 
because  a  cesarean  section  may  })e  the  easiest  and  safest  for  both  patients.  Hebos- 
teotomy  is  not  advisal)le  as  a  primary  selection,  because  of  the  dangers  to  the  soft 
parts.  If  the  disproportion  is  recognized  only  after  the  favorable  time  for  cesarean 
section  is  past,  a  high  degree  of  expectancy  is  to  be  employed.  Occipitoposterior 
positions  are  to  be  early  corrected,  and  then  labor  allowed  to  proceed  until  the  head 
is  firmly  engaged.  High  forceps  operations  are  bad  in  these  cases,  but  not  so  bad 
as  version,  which  should  be  avoided,  if  at  all  possible,  and  especially  in  primi- 
parae.  If  nature  fails,  and  the  accoucheur  with  his  forceps  cannot  bring  the  large 
and  often  stony-hard  head  into  the  pelvis,  extraperitoneal  cesarean  section,  pu- 
biotomy,  and  craniotomy  are  the  alternatives. 

Difficulty  in  the  delivery  of  the  shoulders  is  overcome  as  follows:  (1)  Have  the 
woman  bear  dowTi  forcibly  and  aid  same  by  Kristeller's  expression.  (2)  Try  to 
rotate  the  shoulders  into  a  favorable  diameter,  which  will  usually  be  an  oblique,  by 
pulling  on  the  shoulder  with  the  inside  finger  and  pushing  from  the  outside,  seeking 
to  tuck  the  shoulder  down  behind  the  pubis.  (See  Fig.  536.)  (3)  Try  to  insert 
the  finger  into  the  posterior  axilla  and  thus  pull  the  shoulder  do^^Ti;  failing 
the  posterior,  try  the  anterior;  sometimes  it  is  possible  to  bring  this  one  into  the 
pelvis  from  behind  the  pubis.  (4)  Bring  the  posterior  arm  dowm  and  out,  going 
up  into  the  uterus  with  the  whole  hand;  failing  this,  try  to  bring  the  anterior  arm 
down  from  behind  the  pubis.  At  first  be  very  gentle,  but  if  this  does  not  succeed, 
use  force,  well  applied,  of  course,  risking  a  fracture  of  the  extremity.  In  one  case 
I  deliberately  fractured  the  humerus  and  saved  the  child's  life.  After  one  arm  is 
down  the  extraction  is  usually  possible;  if  not,  get  the  other  arm  also.  Should  the 
child  have  died  during  these  prolonged  manipulations,  all  haste  should  be  at  once 
abandoned;  cleidotomy  and  evisceration  are  now  in  order.  A  deep  episiotomy  is 
almost  always  necessary  in  these  cases,  otherwise  the  perineal  fioor,  including  the 
sphincter  and  rectum,  will  be  injured,  often  extensively. 

Morcellation  of  a  giant  child  is  one  of  the  most  formidable  tasks  that  can  con- 
front the  accoucheur,  and  on  several  occasions  the  vaginal  operation  had  to  be 
abandoned  and  cesarean  section  resorted  to  finally.  Amputation  of  the  uterus 
should  be  done  in  such  cases  to  forestall  sepsis. 


RIGOR  MORTIS 

Should  the  child  die  before  delivery,  the  rigor  mortis  may  be  a  cause  of  dystocia. 
Few  such  cases  are  reported  because  it  seldom  happens  that  the  birth  occurs  during 
this  temporary  condition,  and  many  times  it  is  not  recognized;  finally  it  is  not 
constant.  The  child  figured  on  p.  536  gave  rise  to  real  difficulty  in  labor;  the 
forceps  operation  was  very  difficult;  it  was  necessary  to  insert  the  whole  hand  for 
the  purpose  of  pulling  down  the  shoulders,  and  even  the  trunk  came  hard.  Frac- 
tures of  the  extremities  have  occurred  in  such  deliveries. 


ENLARGEMENT  OF  PARTS  OF  THE  CHILD 

Hydrocephalus  may  give  rise  to  severe  dystocia.  Both  external  and  internal 
forms  are  observed,  and  the  skull  may  contain  several  quarts  of  fluid  and  have 
a  circumference  of  80  cm.  (Fig.  562).  Nothing  is  positively  known  of  the  causes, 
but  syphilis  seems  to  have  some  effect,  and  in  g(nieral  what  was  said  in  the  chapter 
on  Monsters  applies  here.  The  frequent  association  of  hydrocephalus  with  sj^ina 
bifida,  club-foot,  fetal  rickets,  ascites,  and  all  other  defects  of  growih  is  to  be 
emphasized. 


ANOMALIES   OF   THE    PASSENGERS 


639 


Course.— Pregnancy  may  Ix-  inlLrruptcd  hccausc  of  a  non-viable  hydrocephalic 
fetus.  Labor  is  usually  a  little  premature,  and  is  often  notable  liecause  of  weak 
pains,  ViUt,  owing  to  overdistention  and 
thinning  of  the  lower  uterine  segment 
and  the  mechanical  obstruction  to 
labor,  rupture  of  the  uterus  is  a  fre- 
(juent  complication.  For  example,  in 
Schuchard's  74  eases  14  hatl  uterine 
rupture.  Breech  presentation  is  much 
more  frecjuent  tlian  usual,  and  the  s(jft 
head  comes  through  easier  than  when 
it  leads  the  way.  A  small  hydroceph- 
alus may  be  delivered  easily,  or  with 
only  slight  help  from  art;  a  larger  one 
always  gives  trouble,  but,  curiously,  a

THE    PATHOLOGY    OF   LABOR 


high  a  long  time,  and  the  signs  of  thinning  of  the  knver  uterine  segment  are  early 
and  marked.  Sometimes  the  head  bursts  under  the  action  of  strong  pains  or  during 
extraction.  The  fluid  may  escape  outside  or  under  the  skin,  or  a  spina  l)ifida  luirsts 
and  lets  it  out. 

Postpartum  hemorrhage  from  atony  of  the  uterus  and  from  the  freciuent  lacera- 
tions is  observed.  The  mother,  therefore,  is  much  endangered  l)y  hydrocephalus 
unless  it  is  recognized  early,  in  which  event  the  only  mortality  and  morbidity  should 
be  those  of  normal  labor.  Since  the  disease  is  so  fatal  to  the  child,  our  operative 
measures  usually  do  not  consider  it,  but  many  cases  are  recorded  where  the  child

survived  either  spontaneous  or  instrumental  delivery.  Even  in  one  case  where  the 
head  was  perforated  to  facilitate  delivery  the  infant  lived  six  weeks.  Nearly  all 
the  children  die  within  a  few  years,  and  hardly  any  are  cured. 

Diagnosis. — From  the  accoucheur's  standpoint,  this  is  the  most  important, 
and  if  only  the  possibility  of  such  a  complication  be  kept  in  mind,  it  is  very  easy. 
Mistakes  are  due  more  to  carelessness  than  to  ignorance.  Abdominally,  the  large 
size  of  the  uterine  tumor,  the  tense  lower  uterine  segment,  the  rigidity  of  the  abdo- 
men, the  broad  head  (over  the  inlet  or  in  the  fundus),  the  lack  of  engagement,  the 
tendency  to  inertia  uteri,  call  attention  to  some  anomaly.  Vaginally,  the  broad 
sutures  and  large  fontanels,  the  large  flat  elastic  dome  that  seeks  to  enter  the  inlet, 


ANOMALIES    OF   THE    PASSENGEILS  641 

but  remains  high,  will  almost  clinch  the  diaRnosis.  If  the  hones  of  the  cranium  are 
thin,  the  cracklinfi;  craiiiotaljes  will  he  felt,  and  hy  bimanual  jjalpation,  the  use  of 
which  is  too  naich  neglected  in  obstetric  di:it;nosis,  the  immense  size  of  the  head  is 
easily  distinguishable.  In  the  differential  <liafi;nosis  a  sniall  hydrocephalus  must 
be  separated  from  a  lar^c  but  normal  head.  .\  thin-walled  hydrocephalus  may 
simulate  the  baj;  of  waters  or  the  urinary  idadder.  Macerated  and  edematous 
fetal  scalp,  cystic  tumors  on  the  head,  encephaloceles,  and  tou^h  membranes  have 
been  wronj;ly  diagnosed.  A  hydrocephalic  child  presenting  by  the  breech  is  usually 
not  discovered  until  the  head  is  arrested  at  the  inlet.  Occasionally  a  spina  bifida 
or  otlier  deformity  will  excite  suspicion  of  an  a.ss<jciated  hydrocephalus. 

Treatment. — Since  the  child  almost  invarial)ly  dies  and  is  doomed  to  early 
death  even  if  delivered  alive,  all  effort  is  directed  t(j  save  the  mother.  Perforation 
of  the  head  with  a  trocar  is  the  operation  reconunended  by  almost  all  writers.  A 
long  scijisors  will  do  if  a  trocar  is  not  at  hand,  and  the  hole  is  made  in  the  mo.st  ac- 
cessible part  of  the  head.  In  breech  cases  a  spot  beside  the  ear  is  usually  the  Ix'st, 
but  the  ojieration  has  been  performed  throufj;h  the  mouth  and  the  spinal  canal. 
Where  the  po.ssibility  exists  that  the  child  ma\'  survive  the  delivery,  the  spot  chos<'n 
for  the  puncture  should  be  away  from  the  cerebral  sinuses. 

After  the  fluid  is  evacuated  the  collapsed  cranium  offers  little  resistance  to  the 
soft  parts  and  is  usually  cjuickly  delivered.  Should  an  imlication  for  rapid  delivery 
arise  in  a  head  case,  traction  may  be  exerted  on  tlie  colla|)sed  sac,  and  if  this  tears, 
as  is  usual,  the  cranioclast  may  be  a|)plied  to  the  i)a.se  of  tlu'  skull  and  the  cervical 
spinal  column.  Version  may  also  be  done,  but  a  skilful  operator  will  seldom  need 
to  expose  the  uterus  to  th(>  additional  risk  of  rupture  thus  involved. 


DISTENTION  OF  THE  ABDOMEN 

Tliis  uvAV  result  from  ascites,  enlarged  li\'er,  neojjlasms  and  cysts  of  the  liver, 
congenital  cystic  kidneys,  dilated  bladder  or  ureters,  and  a  few  other  isolated  con- 
ditions. Ascites  accompanies  most  of  those  mentioned.  Syphilis  j)lays  an  im- 
portant role  in  the  causation  of  ascites,  fetal  peritonitis,  and  liver  diseases.  The 
diagnosis  of  excessive  abdominal  distention  of  the  fetus  is  seldom  made  until  delay 
in  the  exit  of  the  child  is  manifest.  (Ireat  abdominal  distention  of  the  mother  or 
jiolyhydranmion  will  only  direct  attention  to  the  ])ossil)ility  of  a  fetal  anomaly. 
In  head  cases,  after  the  shoulders  are  reaily  to  escajx'  from  the  vulva,  progress  is 
arrested,  and  in  spite  of  strong  traction  delivery  may  not  be  effected.  Examina- 
tion with  the  whole  hand  will  clear  the  diagnosis.  Fig.  565  shows  a  case  of  lal>or 
arrested  l)v  congenital  cystic  kidneys.  Since  the  breech  tliil  not  advance,  the  hand 
was  inserted  and  the  larg(>  l)elly  easily  circumscribed  with  the  fingers. 

Treatment. — In  head  presentation,  after  th«'  head  is  lx)rn  and  the  distended 
trunk  will  not  come,  several  ribs  and  the  sternum  are  to  be  cxsected  with  Siebold's 
scissors,  the  limgs  and  heart  removed,  the  diajihragm  punctured,  and  the  abdominal 
contents  thus  evacuated.  When  the  breech  i)resents.  simjile  i)uncture  of  the  belly 
suffices  in  ascites,  but  if  there  is  a  solid  tumor  also,  it  is  removed  by  morcellation. 


TOUGH  MEMBRANES 
The  membranes  are  sometimes  a  .source  of  obstruction  to  lal)or.  and  a  slightly 
increased  resistance  here  may  be  the  cause  of  great  delay.  They  may  be  either 
adherent  over  the  internal  os  and  lower  uterine  segment,  thus  preventing  the  ililu- 
tation  of  same,  or  they  may  be  so  tough  that  they  tlo  not  rupture  when  the  cervix 
is  dilated.  In  either  ca.se  labor  is  retarded:  in  the  one  at  the  beginning,  in  the  other 
at  the  end,  of  the  first  stage.  The  secoiul  is  easily  recognized — tlelay  after  complete 
dilatation.

THE    PATHOLOGY    OF   LABOR 


Lack  of  progress  in  the  first  stage  of  labor,  clue  to  adherent  membranes,  may  be 
suspected  when  the  os  dilates  very  slowly  in  sj^ite  of  good  contractions,  the  head 
being  well  do^\^l  in  the  pelvis,  the  completely  effaced  cervix  fitting  it  closely  like 
a  cap,  and  the  membranes  stretched  tightly  over  the  scalp,  Avith  no,  or  hardly  any, 
forewaters.  The  adherences  may  be  felt.  Labor  may  be  delayed  one  or  two  days 
by  such  a  condition. 

Treatment. — In  the  first  stage  it  is  advisable  to  push  up  the  head  a  little, 
loosen  the  membranes  all  around  the  margin  of  the  internal  os  to  the  extent  of  one 
inch,  and  allow  a  little  liquor  amnii  to  come  do^vn,  to  make  a  good  hydrostatic 
dilator.     After  several  hours,  if  delay  is  still  manifest,  it  is  justifiable  to  rupture

marked. 


the  membranes.  Indispensable  conditions  for  this  little  operation  are:  Occipital 
presentation  and  engagement  of  the  head,  effacement  of  the  cervix,  normal  pelvis,  and 
soft  parts. 

When  tough  membranes  do  not  rupture  after  complete  dilatation  of  the  cervix, 
but  delay  is  manifest  for  one  or  two  hours,  it  is  justifiable  to  rupture  them  Con- 
ditions are:  the  pelvis  may  not  be  contracted;  the  child  not  too  large;  the  head 
must  be  well  fixed  on  the  inlet;  the  presentation  and  position  must  be  normal. 
Special  additional  indications  are  required  in  those  cases  where  these  conditions 
are  not  fulfilled. 

After  fixing  the  head  in  the  inlet  from  without  so  as  to  prevent  the  prolapse 
of  the  cord  and  extremities,  the  membranes  are  pierced  with  a  i)ointed  instrument, —

This  is  to  permit  only  the  slow  escape  of  the  liquor  anniii,  which  guarantej-s  the 
safety  of  the  cord.  As  the  licjuid  slowly  trickles  away,  the  assistant  from  the  out- 
side forces  the  head  into  the  jx-lvis.  SlKMiid  the  waters  start  to  c<jme  with  a  rush, 
the  operator  iiolds  tiie  labia  together,  thus  closing  the  vulva.  Some  accoucheurs 
perform  the  oixTation  with  the  i)atient  on  the  side.  When  jxTformed  for  the  proper 
indication  and  under  lilled  conditions,  labor  usually  terminates  very  quickly. 


CHAPTER  LII 

ANOMALIES  OF  THE  PASSAGES 

Dystocia  due  to  anomalies  of  the  soft  parts  is  more  frequent  than  that  due 
to  the  bony  pelvis.  Both  give  the  accoucheur  many  intricate  prol^lems,  especially 
since  he  is  required  to  manage  labors  after  the  numerous  operations  performed  for 
the  relief  of  g-j^iecologic  complaints.  In  order  -will  be  considered:  (1)  Dj^stocia 
due  to  anomalies  of  the  parturient  canal;  (2)  that  due  to  diseases  of  the  bladder — (3) 
of  the  rectum. 

ANOMALIES  OF  THE  PARTURIENT  CANAL 

Most  of  these  have  already  been  studied  under  the  Pathology  of  Pregnancy. 
Reference  has  been  made  to  the  relation  of  tumors  to  pregnancy  and  labor,  to 
hematoma  of  the  pelvic  cellular  tissue,  to  varicosities,  hemorrhoids,  etc.,  and  the 
congenital  deformities  of  the  genitalia  have  also  been  described  under  the  heading 
of  Local  Diseases  Accidental  to  Pregnancy. 

Rigidity  of  the  Cervix. — Older  writers  distinguished  two  kinds:  the  spasmodic 
and  the  anatomic,  in  the  latter  there  being  an  organic  change  in  the  cervical  tissue. 
Spasmodic  rigidity  has  already  been  described  under  Anomalies  of  the  Uterine 
Action.  Rigidity  of  the  cervix  due  to  disease  is  rather  rare,  which  is  remarkable 
when  one  thinks  of  the  number  of  diseased  uteri  which  make  up  the  clientele  of  the 
gynecologist.  During  pregnancy  the  extreme  softening  of  the  tissues  provides 
for  the  great  dilatation  required  in  labor.  Causes  of  such  rigidity  are:  chronic 
cer\dcitis,  scars  from  cautery,  nitrate  of  silver  treatments,  Emmet's  operations,  or 
amputations;  scars  from  old  ulcerative  processes,  especially  those  following  infections 
postpartmn — carcinoma,  etc.;  syphilis,  senility  of  the  tissues  (old  primipara?);  ad- 
hesion of  the  membranes  around  the  internal  os,  conglutination  of  the  external  os. 

Conglutinatio  Orificli  Externi  (Fig.  566)  is  a  condition  where  the  few  circular 
fibers  around  the  external  os  refuse  to  dilate;  as  a  result,  the  cervix  is  not  opened, 
but  thinned  by  the  head,  and  may  be  delivered  externally,  still  covering  the  head. 
The  condition  is  not  a  true  conglutination,  and  a  better  name  should  be  selected 
for  it.  The  os  cannot  always  be  found  by  the  finger,  but  the  opening  can  be  seen 
in  the  speculum  as  a  tiny  hole  with  a  little  mucus,  and  surrounded  by  a  very  red 
ring.  By  pressure  with  the  finger  the  resistance  of  the  external  os  is  overcome,  and 
then  the  dilatation  usually  goes  on  rapidly. 

Old  primiparae  often  have  hard  cervices.  Dilatation  is  very  slow  and  sometimes 
incomplete.  The  cervix  contains  muscular  and  elastic  fibers,  the  muscular  strands 
drawing  the  cervical  walls  actively  apart.  If  the  filjrous  tissue  predominates,  tlicre 
is  no  autogenous  dilatation  of  the  cervix,  and  the  hydrostatic  effect  of  the  bag  of 
waters  is  not  enough.  Since  the  membranes  in  old  primiparae  often  rupture  early, 
the  mechanism  of  the  first  stage  is  deprived  also  of  this  help.  Further,  the  uterine 
pains  in  old  primiparae  often  leave  much  to  be  desired.  The  pelvic  joints  are  rigid 
and  do  not  allow  the  nutation  of  the  sacrum  which  facilitates  delivery,  l)ut  this 
causes  delay  in  the  second  stage  and  mention  of  it  does  not  belong  here. 

Adhesion  of  the  membranes  around  the  internal  os  is  a  not  infrequent  cause 
of  delayed  dilatation,  since  it  prevents  the  action  of  the  dilating  fibers.  ]\Iild 
forms  of  rigidity  or  apparent  rigidity  are  due  to  inefficient  pains.  Owing  to  the 
delayed  labor  and  occasionally  to  circulatory  disturbance,  the  cervix  gets  thicker,

mi 


harder,  inelastic,  and  sometimes  edematous.  Xo  pnjK^'ss  may  l)e  n(jte(l  for  hours, 
and,  unless  relieved,  the  ease  passes  into  the  dan^^erous  class  of  ohstructed  lahor. 

Syphihs  causes  a  very  serious  form  of  e<'rvieal  rigidity,  and  is,  fortunately,  rare; 
the  whole  cervix  is  changed  into  a  tough,  fibrous,  undilatahle  tulw.  Cesarean 
section  and  craniotomy  have  been  found  necessary.  Scars  from  ulceration  may 
close  up  the  cervix  so  that  the  finest  probe  may  not  discover  tin*  j)a.ssaKe.  and  if, 
as  .sometimes  happens,  the  cervix  has  slouglied  olT,  the  vault  of  the  vagina  may  Ix? 
one  arched,  smooth  scar,  in  which  the  opening  into  the  uterus  cannot  be  found. 
One  of  my  Porro  cesareans  was  for  this  condition,  complicat<'d  by  a  rectovaginal 
fistula — all  the  result  of  a  previous  puerperal  septic  process. 

Labor,  in  cases  of  cervical  disease,  shows  delay  in  the  first  stage,  and  a  great 


Fio.  5G6. — CoNoLiTiNATi>>  Okifkii  Extf.rm. 


deal  depends  on  the  site  and  extent  of  the  stricture.  If  it  is  in  the  supravaginal 
portion  of  the  cervix,  the  worst  forms  of  dystocia  arise;  if  in  the  vaginal  i^rtion, 
the  case  is  easily  iiandled.  and  there  are  intermediate  forms.  I'nder  the  action  of 
the  pains  the  cervix  dilates  up  to  the  jxiint  of  ol)struction.  If  the  pains  are  strong, 
the  uterus  healthy,  and  the  stricture  not  too  rigid,  nature  finally  succeeds  in  pro- 
curing a  passage  for  the  child.  If  not,  labor  stops,  the  child  dies,  tiie  cervix  may 
tear,  the  child  being  born  througii  the  rent,  or  the  uterus  may  ruptun-  and  the  chiUi 
escape  into  the  alxlominal  cavity,  or  (rarest)  the  cervix  may  tear  off  circularly  in 
part  or  in  toto.  M  the  Chicago  Lying-in  Hospital  a  olix-urynter.  put  in  the 
uterus  to  facilitate  delivery  through  a  scarn>d.  indurated  cervix,  was  exi>elle<l, 
bringing  the  cervix  torn  ofT  circularly  with  it.  Usually  the  i>osterior  cervix  is 
torn,  the  child  escaping  through  the  rent,  the  ring-like  piece  hanginc  nlonL^ide  it. 


646  THE    PATHOLOGY    OF   LABOR 

Severe  dystocia  due  to  pathologic  cervices  is  rare.  Slight  induration,  which 
lengthens  labor  but  allows  spontaneous  termination,  is  fairly  common.  A  large 
number  of  children  are  lost  through  delay  caused  by  rigidity  of  the  cervix  (Seitz). 

Diagnosis. — Not  every  hard  cervix  is  caused  by  anatomic  disease.  As  was  said, 
abnormal  uterine  action  can  produce  secondary  cervical  rigidity.  The  diagnosis 
must  comprise  the  cause,  the  nature,  the  location,  and  the  extent  of  the  stricture, 
also  the  relation  of  surrounding  organs;  for  example,  as  in  one  case  where  the  cervix 
in  toto  was  missing,  the  bladder  la}'  close  to  the  rectum,  and  a  rectovaginal  fistula 
coexisted.  "Relative  rigidity"  of  the  cervix  exists  when  an  indication  for  delivery 
arises,  but  the  cervix  is  closed,  though  normal. 

Treatment. — Cesarean  section  as  a  primary  operation  is  to  be  performed  where 
a  careful  examination  has  proved  that  obstruction  exists,  unamenable  to  the 
ordinary  methods.  If  the  stenosis  of  the  cervix  is  very  marked,  the  Porro  operation 
should  be  done,  because  the  passage  will  be  too  small  to  permit  the  escape  of  the 
lochia.  In  cases  where  the  stricture  does  not  appear  to  offer  an  insuperable  obstacle 
to  labor,  the  action  of  strong  pains  is  to  be  awaited.  When  it  is  evident  that 
nature  has  accomplished  as  much  as  she  is  able,  art  steps  in  to  aid  in  overcoming 
the  rigidity.  Five  methods  of  dilatation  of  the  cervix  are  practised:  (1)  By  means 
of  the  hands,  advocated  since  the  time  of  Celsus,  and  perfected  by  Bonnaire  and 
Harris;  (2)  the  use  of  rubber  balloons;  (3)  instrumental  dilators  of  the  glove- 
stretcher  design,  of  which  Bossi's  is  the  best  known;  (4)  the  incisions  of  Diihrssen — 
hysterostomotomy ;    (5)  the  vaginal  cesarean  section  of  Diihrssen. 

In  mild  cases,  where  the  cervix  is  effaced  and  the  os  more  or  less  dilated,  the 
fingers  usually  are  able  to  stretch  the  opening  sufficiently  to  permit  delivery. 
Almost  invariably  the  cer\dx  tears  more  or  less.  If  the  ring  is  too  tough  to  be 
stretched,  clean  incisions  radiating  to  the  fornices  may  be  made.  When  the 
cervix  is  not  effaced,  these  methods  are  dangerous  and  inefficient.  If  an  indication 
for  rapid  delivery  on  the  part  of  the  mother  or  child  does  not  exist,  a  metreurynter 
is  to  be  put  into  the  uterus  and  the  effect  of  the  hydrostatic  dilatation  tried.  Often 
the  cervix  will  soften  sufficiently.  If  it  does  not,  or  if  delivery  is  required,  the 
vaginal  cesarean  section  is  the  operation  of  choice.  Bossi's  dilator  is  not  to  be 
recommended.  (See  Chapter  LXIX.)  In  cases  of  amiular  rupture  of  the  cervix 
nothing  can  be  done  if  the  amputation  is  complete  except  to  whip  the  vaginal  edge 
over  the  raw  surface  as  much  as  possible.  If  incomplete,  the  detached  portion 
may  be  sutured  in  place  if  the  accoucheur  considers  its  nutrition  not  too  much 
compromised;  otherwise  it  should  be  removed,  always  cutting  off  as  little  as  pos- 
sible, to  avoid  stricture  of  the  cervix,  and  covering  the  raw  surface  with  the  vagina 
if  it  can  be  gotten  into  place. 

Stenosis  of  the  vagina  is  an  occasional  cause  of  dystocia. 

Etiology. — Congenital  deformities,  duplicity  (already  considered),  atresia 
(usually  causes  sterility),  vaginal  bridges  or  septa  (the  relics  of  congenital  duplicity), 
tumors  in  and  near  the  vagina,  hematoma  of  the  neighboring  cellular  tissue,  cica- 
trices from  previous  ulcerative  processes,  puerperal  sepsis  or  injury  following  labor, 
scarlet  fever,  diphtheria,  measles,  variola,  syphilis,  and  gonorrhea.  In  one  of  the 
author's  consultations  the  cervix  and  vagina  sloughed  out  in  toto  after  a  hard,  high, 
forceps  delivery,  leaving  a  narrow,  tortuous  passage,  hardly  sufficient  for  the  men- 
strual discharges.  In  another,  after  measles,  a  portion  of  the  vagina  became  saccu- 
lated and  contained  pus,  and  the  cavity  burst  during  (Unlivery.  (See  also  Brindeau.) 
Sometimes,  in  small  women,  the  vagina  is  too  narrow  for  safe  delivery.  In  women 
who  have  been  married  a  long  time  without  children,  and  in  prostitutes,  the  vagina 
may  be  constricted  and  tough,  so  that  it  will  not  dilate,  but  when  forced,  tears. 
Old  primiparse  also  are  likeh^  to  have  rigid  vaginas,  and  in  cases  of  frigiditas  sexu- 
alis  the  author  has  often  found  a  short,  dry,  indistensible  passage.  Finally,  the 
vagina  may  be  relatively  too  small;  that  is,  it  may  ])e  normal,  l)ut  in  the  presence 
of  some  indication  for  immediate  delivery  it  is  unprepared  for  rapid  dilatation. 


ANO.MAI.IKS    OF    THE    PASSAGES  647 

Lab(jr  in  cases  of  vaKiiuil  atresia  is  iKjt  (Idaycd  until  tlic  la-ad  n-achcs  the 
point  of  obstruction.  Congenital  septa  or  bridRes  are  usually  i)ushed  aside  or 
torn  throuKJi  by  the  i)resentiiiK  part;  rarely  is  discission  re(|uired.  Tunnjrs  may 
be  flattened  or  even  extruded  before  the  head,  as  occurn-d  in  one  <-ase  of  large 
vuKinal  cyst  in  the  author's  j)ractice.  \aninal  rigidity  is  usually  overcome  by  the 
IKjwers  of  nature,  the  vagina  softening  (jr  dilating,  tlujugh  sometimes  splitting  longi- 
tudinally— the  last  oftener  during  oj)erativ(!  interferenc<'.  Even  a  scar  may  some- 
times soften  and  dilate  under  the  influence  of  the  pains,  but  scars  often  give  rise 
to  obstinate  dystocia. 

Didiinosis. — This  is  easy,  the  finger  meeting  a  hard  ring  or  narrow  passage 
beyond  which  the  cervix  is  felt,  but  eare  is  recjuired  to  determine  how  nmch  the 
contiguous  organs  are  involved.  Soim-times  the  vagina  folds  up  Ix-fore  the  on- 
coming head  and  a  stricture  is  sinnilated  (Fig.  US).  Such  a  fold  is  soft  and  easily 
pushed  open.  Tiie  full  rectum  may  encroach  on  the  vagina  (Fig.  508;  and  simul.-ite 
a  i)elvic  tumor. 

Treatment. — Cesarean  section  is  performed  when  the  first  examination  shows 
an  insuperable  obstacle  to  delivery,  anil  if  the  pa.^sage  is  ai)i)arently  too  small  to 
allow  the  escape  of  the  lochia,  the  uterus  nuist  l>e  amputated.  A  cicatricial  .septum 
may  be  split  l)y  three  or  f(jur  radial  incision.s,  care  being  exerci.sed  to  avoid  opening 
the  rectum  or  l)ladder.  ( )ccasionally  a  stricture  may  be  dilated  with  a  coljx'urynter. 
A  rigid  or  small  vagina  may  be  better  prepared  for  the  dilatation  it  has  to 
undergo  by  means  of  the  coliK'urjTiter.  During  operative  delivery  a  narrow,  tight 
vagina  must  not  l)e  allowed  to  burst:  it  is  better  to  incise  it.  Since  the  tears  almost 
always  occur  in  the  lower  half,  a  deep  vaginoperineal  incision  will  usually  .suffice 
{vide  infra).  A  vaginal  tumor  may  be  enucleated,  or  at  least  enough  of  it  removed 
to  permit  extraction  of  the  fetus.  A  cyst  may  be  enucleated  or,  if  need  be, 
inmctured.  A  hematoma  may  be  punctured,  the  clot  evacuated,  and,  after  de- 
livery, the  cjuily  packed  with  gauze. 

Rigid  Pelvic  Floor. — Two  forms  of  rigidity  of  the  pelvic  floor  may  be  distin- 
guished, anatomic  and  spasmodic.  Disease  of  the  muscles  or  connective  ti.ssue  may 
compromise  the  dilatation  of  the  parts — for  example,  syphilis,  scars  from  injury 
or  from  jirevious  lal)()rs,  the  cicatrices  following  rei)air  operaticjns,  hematoma,  and 
hypertrophy  of  tlie  muscle,  liicycie-riding  hardens  the  perineum,  and  old  primi- 
pariu  will  often  present  such  a  comi)lication  in  addition  to  rigitl  vagina.  Spa.smodic 
rigidity  may  be  found  in  those  women  sui)ject  to  vaginismus;  it  is  a  spasm  of  the 
levator  ani  muscle,  and  in  one  of  Pinartl's  ca.ses  nec«'ssitated  the  use  of  forceps. 
Sometimes  a  nervous,  apprelu-nsive  jiarturient  will  contract  the  outlet  of  the  pelvis 
and  sto])  labor.     Here  a  narcotic,  by  relieving  the  pain,  aids  delivery. 

Lal)or  progresses  until  the  presenting  jiart  is  on  the  perineum,  and  then  delay 
is  manifest.  If  the  parturient  has  a  gooil  re.serve  .store  of  strength,  she  will  Ik«  able 
to  overcome  the  added  resistance.  If  not, — if  it  has  been  wasted  by  ])remature 
bearing-down  eflorts  or  if  the  woman  has  an  oversensiti/.ed  n«Tvous  system, — arrest 
of  the  head  now  occurs  and  exhaustion  begins,  the  life  of  the  fetus  also  coming 
into  jeopardy. 

Seitz  (lac.  cit.)  shows  the  impurtance  of  rigid  pelvic  floor  in  his  statistics  from 
the  Munich  Maternity,  l»y  i)r()ving  that  one-third  of  the  fetal  d<'at lis  in  head  pre.*;- 
entation  are  due  to  delay  in  labor  at  this  point.  Our  own  exiM'rience  c(»nfirms  this 
and  emphasizes  the  strong  necessity  to  listen  to  the  fetal  heart-tones  everj-  few 
minutes  towartl  the  end  of  the  .second  stage.  \\\  following  this  practice  a  very 
large  number  of  children  will  be  saved. 

Z)/o(//io.s-/'.s-.— Delay  at  tiie  end  of  tlu'  second  stage  demands  careful  examination. 
One  will  diagnose  a  rigid  jH'lvic  diaphragm  only  when  it  is  manifest  that  the  head 
presses  firmly  on  the  pelvic  floor  but  does  not  advance.  To  l)e  eliminated  as  cau-ses 
of  delay  are  contracted  bony  outlet  (funnel  or  ma.sculine  ix'lvis).  overgrowth  of  the 
child,  faulty   rotation    (deep  transverse  arrest — occipitoposterior),  enlargement  of 


648  THE    PATHOLOGY    OF    LABOR 

the  trunk  of  the  fetus,  and  primarily  weak  pains.  The  cUagnosis  of  an  asphyxia 
threatening  the  child  forms  part  of  the  accoucheur's  duties  at  the  same  time. 

Treatment. — When  the  j^arturient  has  shown  her  inability  to  overcome  the 
resistant  pelvic  floor,  or  when  the  child  begins  to  show  signs  of  asphyxia,  delivery 
must  be  accomplished.  One  should  not  wait  until  the  mother  is  exhausted  or 
until  her  nervous  system  is  tried  to  the  limit;  rather  one  should  determine  how 
much  nature  can  accomplish,  not  how  much  she  can  endure.  Resistance  at  the 
outlet  may  often  be  overcome  l)y  a  deep  episiotomy,  and  this  little  operation  Avill 
obviate  many  applications  of  the  forceps.  If  the  birth  does  not  now  occur,  forceps 
are  applied  and  nothing  has  been  lost,  because  in  all  probal^ility  episiotomy  would 
have  been  done  in  any  case  to  avoid  deep  rupture  of  the  perineum.  Tetanic  spasm 
of  the  levator  ani  is  treated  by  anesthesia,  failing  which  the  forceps  are  used. 

Stenosis  of  the  Vulva. — Congenital  closure  of  the  vulva  is  usually  complete,  and, 
w^ien  an  opening  exists,  it  leads  to  a  deformed  uterus  and  tubes,  so  that  conception 
is  almost  unknowTi.  As  a  unicum  may  be  mentioned  the  case  of  von  Meer,  of 
pregnancy  in  the  uterus  comiected  with  the  bladder,  coitus,  and  abortion  per 
urethram.  Acquired  closure  of  the  vulva  may  result  from  injury — burning  with 
fire  or  acids  (author's  case),  inflammation  with  ulceration  in  childhood.  A  pin- 
hole hjTnen  may  offer  a  distinct  resistance  to  the  exit  of  the  head.  In  one  of  the 
author's  cases,  when  cut,  the  hymen  was  one-fourth  inch  thick.  Hymenal  septa 
may  offer  a  slight  barrier  to  progress,  but  they  usually  break,  or  can  be  easily 
snipped  in  two.  Edema  of  the  vulva  resulting  from  prolonged  and  obstructed 
labor  may  sometimes  be  very  great,  and  the  labia  may  even  slough  off.  This  is 
usually  due  to  concomitant  infection.  Sometimes  the  edema  seems  to  aid  the 
dilatation  of  the  vulva;  again  it  seems  to  predispose  to  lacerations  of  the  tissues. 
Varicosities  do  not  delay  labor,  but  they  comport  the  dangers  of  hemorrhage  and 
hematoma. 

Treatment. — When  it  is  plain  that  the  vulvar  outlet  is  holding  the  presenting 
part  back,  the  resisting  ring  is  either  to  be  stretched  with  the  fingers  or  incised 
(episiotomy).  A  closed  hymen  is  incised  radially.  In  the  author's  case  of  sten- 
osis of  the  vulva  due  to  carbolic  acid  burn  the  child  was  delivered  outside  the  bony 
pelvis  under  a  tough,  glistening  scar,  w^hich,  with  the  skin,  dissected  itself  off  the 
perineum  and  thighs  to  the  extent  of  6  inches.  After  a  long  mecUan  incision  had 
released  the  dead  fetus  the  flaps  were  readjusted  and  sewn  in  place  so  as  to  form  a 
new  vulva  and  a  shallow  vagina. 

Infantile  Genitalia. — Infantilism  of  the  genitalia  is  not  very  rare,  and  often 
leads  to  absolute  or  "one-child"  sterilitj'.  Dysmenorrhea,  dyspareunia,  frigid- 
itas  sexualis,  nervous  weakness,  and  a  syndrome  which  resembles  Basedow's  dis- 
ease are  the  usual  symptoms,  and  a  tendency  to  firm  obesity  is  noticeable.  The 
vulva  is  small,  with  little  hair;  the  vagina  narrow,  short,  and  hard,  with  little 
secretion;  the  forniccs  flat,  the  uterus  being  either  normal  in  size,  but  infantile  in 
shape  (large  cervix  with  small  fundus),  or  very  small  and  undeveloped.  Not  seldom 
it  is  found  bent  or  curled  on  itself  in  sharp,  retroposed  anteflexion.  Bossi  called  the 
cervix  "tapir  nosed."  The  pelvis  is  either  generally  contracted,  of  infantile  tj-pe, 
or  it  is  large,  with  masculine  lines  and  a  funnel  outlet.  It  seems  to  me  that  perhaps 
the  thyroid  gland  is  concerned  in  this  hypoplasia.  ^Marasmus  of  enteric  origin  in 
early  life  and  prematurity  are  also  causative.  Should  pregnancy  ensue,  abortion 
in  the  early  months  is  frequent,  and  this  often  ends  the  reproductive  effort  of  the  in- 
dividual. Lalior  is  characterized  l)y  weak  pains  and  delay  in  the  second  stage. 
This  comes  from  both  the  rigid  vagina  and  perineinn  and  the  ])ony  outlet.  In- 
strumental delivery  is  often  required,  and  it  is  usually  attended  by  extensive  lac- 
erations. It  is  highly  important  to  preserve  the  fetus  in  these  cases,  because  the 
first  is  so  often  the  only  pregnancy.  Later  effects,  as  pointed  out  by  Pfannenstiel, 
are  retroflexio  uteri  from  overstretching  of  the  isthmus,  and  jirolapsus  from  in- 
jury and  overdistention  of  the  levator  ani  with  subsecjuent  atrophy.

oeeipitoposterior  jjosition,  heeause  the  hack  at  oiic<'  canje  to  the  front  after  the 
viseus  was  emi)ti('(l  hy  catheter.  It  causes  weak  pains  and  inti-rfercs  with  hearinR- 
down  efforts,  and  thus  increases  the  luunher  of  forceps  ojM'rations.  A  eysto<-ele 
may  delay  the  head,  and  itself  run  the  danger  of  severe  contusion  or  l)ursting. 
After  the  birth  of  the  child  the  full  bladder  may  obstruct  the  delivery  of  the  placenta 
or  weaken  the  uterine  contractions,  in  either  case  causing  p<jstpartum  hemorrhage 
or  retention  of  the  placenta. 

The  diagnosis  is  easily  made,  there  Ixing  a  soft,  fluctuating,  rounded  tumor

stretching  from  the  j)ui)is  toward  or  to  the  navel.  It  resembles  the  thimied-<>ut 
lower  uterine  segment,  but  catlieterization  will  settle  the  diagnosis  if  the  pres<'nee 
of  distinct  fluctuation  has  not  already  done  so.  The  treatment  is  catheterization 
with  a  soft-rubl)i'r  catheter,  pushing  up  the  head  if  nect-ssary. 

Tumors  of  the  bladder  have  seklom  been  known  .^riously  to  complicate 
delivery — two  cases  of  fibroma  are  on  record.  \  esical  calculi  may  eaus«'  serious 
trouble;  th(>  traumatism  t)f  labor  may  crush  them  or  crush  the  bladtler-wall. 
resulting  in  fistula.  It  is  best  to  remove  the  stone  per  vaginam  late  in  pregnancy. 
If  labor  has  started,  it  may  be  po.s.sible  to  push  the  stone  and  the  bladder  out  of  the 
pc>lvis  and  lead  the  head  into  it,  but  it  may  l)e  necessary  to  i>erfonn  lithotomy  during 
labor.  The  diagnosis  is  easy  if  all  the  i>ossibilities  are  considered.  A  stone  was 
once  mistaken  for  a  jielvic  exostosis. 

The  Rectum. — A  full  rectum  mav  act  very  much  like  the  full  bladder  in  pre-

venting  engagement  and  modifying  uterine  action.  One  danger  of  the  full  rectum 
which  is  not  sufficiently  emphasized  is  infection  from  feces  expelled  during  the 
birth  of  the  child.  In  spite  of  extraordinary  precautions  on  the  part  of  the  accou- 
cheur, particles  of  feces  may  be  carried  into  the  genitals  and  give  rise  to  fatal 
puerperal  infection.  When  the  head  is  held  above  the  pelvis  by  the  full  viscus, 
faulty  presentations,  positions,  and  attitudes  may  result.  Ofttimes  a  colonic 
flushing  will,  by  emptying  the  pelvis,  permit  engagement,  which  is  followed  by 
rapid  delivery  (Fig.  508). 

Tumors  of  the  rectum  may  cause  sufficient  dystocia  to  recjuire  cesarean  section. 


Fig.  568. — Full  Rectum  as  Obstruction. 

In  one  of  my  cases  a  large  gonorrheal  stricture  of  the  rectum,  with  its  surrounding 
cellular  tissue  infiltration,  caused  obstruction  and  prolonged  delaj^  in  delivery, 
during  which  the  child  became  asphyxiated.  Forceps  were  employed  to  overcome 
the  obstacle,  but  the  child  succumbed  in  eighteen  hours. 

Fissures  of  the  anus  are  a  common  secjuence  of  the  great  stretching  of  the 
anus  during  labor.  They  cause  painful  defecation  and  bloody  and  purulent  dis- 
charges in  the  late  pucrperium.  A  few  applications  of  10  per  cent,  nitrate  of  silver, 
with  perhaps  a  little  stretching  of  the  muscle,  usually  suffice  to  cure  them.

ANOMALIES  OF  THE  BONY  PELVIS 


As  much  variation  is  fouml  amouK  female  pelves  as  in  female  features.  A 
perfectly  symmetric  jx-lvis  is  the  «rreatest  rarity.  Tramoiid.  of  l^iris.  who  i)repan'(l 
many  thousamls  of  them,  found  hardly  one  in  .")0()(J  limt  was  nearly  jx-rfect.  The 
variations  are  intlividual,  racial,  pathologic.  Large  women  usually  have  large 
pelves,  w^omen  of  masculine  hahitus  have  masculine  jjelves.  small  women  usually 
have  small  pelves,  women  of  delicate.  elTeminate  constitution  have  slend<'r  hones, 
while  the  muscular  individual  develops  a  strong,  rigid  pelvis.  Racial  differences 
al.so  e.xist,  hut  have  not  i)een 
sufficiently  studietl.  In  general 
there  are  four  forms,  judging 
from  the  shape  of  the  inlet: 
The  transverse  ellijjse.  the 
heart  shajie,  the  round,  and 
the  anteroposterior  ellipse. 
European  women  have  the 
large  transverse  elli])tic,  with 
a  tendency  to  heart-shaped 
inlet.  The  Bush  women  of 
Australia,  the  African  negress, 
and  the  Indian  women  have 
a  round  pelvis,  hut  also  with 
a  tendency  to  lengthening  i)i 
the  anteroposterior  diameters. 
English,  Irish,  and  German 
women  have  large  cordate 
pelves,  the  French  a  large  pel- 
vic canal  with  tendency  to 
small  bones.  Jewish  wouKm 
have  small  pelves. 

Thestudy  of  the  adult  pel- 
vis is  much  facilitated  by  fol- 
lowing its  development  from 
the  fetal  stage,  and  the  study 
of  the  effects  of  disease  in  early 
childhood  ui)on  the  configura- 
tion of  the  l)ones  would  throw 
much  light  on  this  comi^licated 
subject.     Here  exists  a  fertile 

field  for  investigation.  The  pelvis  of  the  new-l)orn  child  (P'ig.  569)  is  long, 
narrow  from  side  to  side,  and  converges,  funnel  shaped,  toward  the  outlet. 
The  sacrum  is  long  and  straight;  the  botlies  of  the  vertebne  do  not  project 
from  between  the  wings,  which  are  small.  The  promontory  is  high  an<l  not 
prominent;  the  pelvic  inclination  is  marked.  Fehling  was  able  to  distinguish 
tlifferences  between  the  male  and  female  i>elvis  even  in  fetal  life,  but  the  great«'st 
changes  occur  during  the  years  of  most  activi'  sk«'h'tal  development.  Since  the 
time  of  Denman  the  factors  in  the  development  of  the  sha|H'  of  the  atlult  ix'lvis

THE    PATHOLOGY    OF    LABOR 


Fehling,  Bayer,  Balandin,  Freund,  Breus,  and  Kolisko  might  be  mentioned  as  a 
few  of  the  many  who  took  part  in  it.  We  cannot  go  into  the  details  of  the  dis- 
cussion, but  briefly  may  give  the  results,  which  are  now  quite  well  established. 
In  general  there  are  two  factors  which  form  the  adult  pelvis,  the  first  and  most 
important  being  the  inherent  property  of  gro^vth  of  the  bones;  the  second,  the 
mechanical  influences  exerted  on  the  growing  child.  That  the  inherent  growth- 
tendencies  of  the  liones  are  the  determining  factors  is  proved  bj' — (a)  The  pelvis 
of  the  new-born  girl  already  differs  slightly  from  that  of  the  boy;  and  (6)  though 
subjected  to  the  same  mechanical  influences,  assumes,  in  its  maturation,  a  much 
different  shape;  (c)  even  when  distorted  by  disease,  after  the  cause  is  removed, 
nature  tries  to  correct  the  deformity,  for  example,  in  rachitis;  (d)  when  other 
anomalies  of  gro^\'th  are  present  abnormality  of  the  jiclvis  often  coexists,  for  example, 
aplasia  of  the  genitals  with  infantile  pelvis. 

]\Iechanical  influences  after  birth  are  auxiliary  in  the  production  of  the  devel- 
oped pelvis.     Litzmann  (1861)  and  H.  von  Meyer  emphasized  the  action  of  the 
pressure  of  the  trunk,  and  considered  also  the  resistance  of  the  pelvic  bones  and  car- 
tilages and  the  dragging  force 
of  the  muscles  and  ligaments  of 
the  pelvis. 

The  three  bones  of  the  pel- 
vis are  put  together  so  that  the 
sacrum  does  not  act  like  a  key- 
stone or  wedge.  The  sacrum  is 
movable,  being  held  in  place  by 
the  ligaments,  aided  by  the  inter- 
locking of  the  roughnesses  of  the 
a])posed  articular  surfaces  of  the 
ilia. 

In  the  growing  child  the 
line  of  direction  falls  through  a 
point  somewhat  anterior  to  the 
sacrum.  This  causes  pressure  to 
be  exerted  on  the  first  sacral  ver- 
tebra when  the  child  is  erect  or 
sitting.  The  lower  end  of  the 
sacrum  is  prevented  from  going 
backward  by  the  strong  sacro- 
sciatic  ligaments.  A  bending  of 
the  sacrum,  therefore,  occurs  in 
the  sagittal  diameter,  which  is  most  marked  at  the  third  sacral  vertebra. 

A  tendency  of  the  sacrum  to  become  concave  from  side  to  side,  which  might 
result  from  the  same  factors,  is  counteracted  by  the  weight  of  the  body,  transmitted 
through  the  spinal  column  to  the  sacrum  (the  "  body  or  trunk  pressure  " ) ,  forcing  the 
bodies  of  the  sacral  vertebrae  dowTiward.  In  pelves  softened  by  disease  this  forcing 
dovra  and  forward  of  the  vertebral  bodies  is  very  pronounced.  Another  effect  of  this 
trunk  pressure  is  the  flattening  of  the  posterior  portions  of  the  bodies  of  the  vertebrae. 
The  body  pressure  also  forces  the  wdiole  sacrum,  and,  of  course,  the  promontor}', 
more  into  the  pelvis;  when  the  sacrum  goes  down,  it  puts  the  iliosacral  ligaments 
on  the  stretch,  and  this  gives  the  posterior  iliac  spines  the  tendency  to  approach 
each  other.  This  would  be  attended  with  a  separation  of  the  symphysis  were 
this  joint  loose  (Fig.  571).  Let  us  call  this  tendency  of  the  innominate  bones  to 
separate  at  the  pubis,  because  of  the  iliosacral  ligaments  tugging  at  the  posterior 
spines,  ''transverse  tension."  A  marked  tension  posteriorly  with  soft  bones,  but 
fast  symphysis,  would  result  in  the  approach  of  the  symphysis  to  the  promontory. 
But  this  is  counteracted  by  the  pressure  of  the  heads  of  the  femora  in  the  acetabula,

whicli  forces  the  hones  upward  and  inward.     Let    us   call   this   pressure  "lateral 
pressure"  (Figs.  571  and  572).

weights  during  the  formative  period.  All  these  mechanical  results  would  be  exag- 
gerated if  the  resistance  of  the  bones  and  cartilages  were  reduced,  as  in  rachitis 
and  osteomalacia,  or  removed,  as  in  split  pelvis. 

IMuscular  action  has  a  decided  influence  on  the  formation  of  the  pelvis;  for 
example,  the  outward  rolling  of  the  lower  edges  of  the  descending  rami  pubis  is 
probably  due  to  traction  by  the  adductores  femoris. 

A  harmonious  operation  of  all  the  above  factors  is  necessary  for  the  production 
of  the  normal  pelvis,  and,  in  the  study  of  the  pathologic,  we  shall  see  how  abnormal 
tendencies  of  gro\\'th,  abnormal  application  of  the  body  pressure,  reduced  resis- 
tances, disease  of  the  bones  and  joints,  etc.,  produce  distorted  pelves. 

Classification. — Scientifically,  the  best  way  to  classify  abnormal  pelves  would 
be  accorchng  to  their  etiologj'  or  patholog}^  Kolisko  presents  12  different  sj'stems, 
proposed  b}"  various  German,  English,  and  French  authors  since  1840,  but  admits 
that  all,  incluchng  his  own,  are  unsatisfactory.  This  is  because  the  genesis  and 
pathology  of  most  of  the  pelves  is  either  unknown  or  not  universally  agreed  upon, 
so  that  they  can  be  given  a  settled  place  in  any  classification,  and,  further,  a  sj'stem 
that  would  suit  the  anatomist  would  not  aid  the  obstetrician  in  his  daily  practice. 
The  latter  would  prefer  a  system  based  upon  the  dimensional  and  morphologic 
characters  of  pelves,  because  these  are  what  he  has  to  consider  at  the  bedside. 
Litzmann,  in  1861,  proposed  such  a  classification,  and  nearly  all  obstetric  writers 
since  have  adopted  it,  at  least  as  a  basis  for  their  presentment  of  the  subject.

(c)  Local  and  symmetric,  double  oblique  oval,  split  pelvis,  arrest  of  development  of 

sacrum,  etc. 
VI.  Atypical  deformities,  as  tumors,  fractures. 

It  must  be  remembered  that  several  causes  can  combine  to  produce  a  pelvis 
which  may  be  fitted  into  no  classification — for  example,  a  child  born  with  a  dis- 
location of  one  hip  becomes  rachitic,  or  a  rachitic  child  develops  a  tubercular  hip, 
etc.  If  the  deforming  disease  appears  late  in  life,  the  pelvis  is  altered  in  a  way- 
differing  from  that  resulting  from  early  changes;  variations  in  degree  of  deformity, 
also  of  location,  occur,  and  these,  with  many  other  factors,  sometimes  produce 
pelves  of  most  bizarre  shapes  and  irregular  sizes. 

Too  Large  Pelves. — Dystocia  may  arise  from  the  pelvis  being  too  large,  and 
usually  this  is  found  in  large  women,  but  as  these,  as  a  rule,  have  big  babies,  the 
proper  proportion  is  reestablished.  Often  enough  a  large,  apparently  well-built 
woman  will  have  a  difficult  delivery,  even  resulting  in  the  death  of  the  child,  and 
on  investigation  the  accoucheur  is  surprised  to  find  a  large  inlet,  but  with  a  small 
pelvic  outlet,  that  is,  a  large  funnel-shaped  pelvis.  If  the  pelvis  is  too  large,  all 
the  diameters  exceeding  the  normal  by  2  cm.  or  more,  the  mechanism  of  labor  may 
be  influenced.  During  pregnancy  the  head  sinks  low  down  and  causes  pressure 
syinptoms  in  the  bladder  and  rectum.  In  labor  the  soft  parts  are  exposed  to  the 
full  force  of  the  powers,  and  often  tear  or  stretch  too  much,  permitting  the  rapid 
exit  of  the  fetus.  Subsequent  relaxation  of  the  pelvic  floor  and  prolapse  of  the 
uterus  may  result.  Flexion  and  rotation  of  the  head  are  not  so  marked,  and  occi- 
pitoposterior  positions  are  common — all  of  which  may  cause  serious  dystocia  if  not 
promptly  recognized.  It  has  seemed  to  the  author  that  such  women  have  a  tendency 
to  postpartum  hemorrhage. 

Anomalies  of  pelvic  inclination  may  cause  dystocia  by  influencing  the  direction 
of  the  uterine  axis.  Engagement  of  tiie  head  may  be  delayed  by  too  great  incli- 
nation, and  the  pelvic  floor  is  endangered  by  the  direct  pressure  of  the  head 
when  the  outlet  lies  in  a  way  to  receive  the  full  force  of  the  uterine  action.  On  the 
living  it  is  very  difficult  to  measure  the  pelvic  inclination,  except  with  Neuman  and 
Ehrenfest's  complicated  cliseometer,  but  the  skilful  accoucheur  can  usually  discover 
the  abnormality  if  it  is  causing  dystocia,  and,  by  raising  or  lowering  the  parturient's 
trinik,  bring  the  axis  of  the  uterus  into  parallelism  with  that  of  the  i)elvic  canal.

Definition  and  Frequency.  Aiitli(»rs  ticmrally  state  tliat  a  pelvis  which  showH 
a  (liiiiiiiiit  ion  ol  1  '  J  to  2  cm.  in  an  important  diameter  should  he  calletl  contracti'd, 
hut  clinically  every  peKis  should  he  so  desif>;nated  when  it  is  certain  that  the  anomaly 
has  protluced  a  ilisturhing  iutlueuce  on  the  parturient  function.  It  is  also  a  general 
practice,  since  contraction  at  this  point  is  the  most  conunon,  to  u.se  tlje  conjugata 
vera  as  the  determininfi;  diameter,  and  to  say  that  a  pelvis  is  contracted  when  the 
conju«i;ata  vera  is  shortenecl,  and,  too,  the  dejin-e  of  the  contraction  is  measured  hy 
the  amoiuit  of  the  shorteninj^  of  the  conjufjata  vera.  Thus  Michai'lis.  who  really 
foundedthescientificol)stetricstudyofpelves,i)laced  the  heninninn  of  contracted  pel- 
vis at  a  10cm.C.\'.in  the  justominor  types, and  at  9.5  cm. in  tho.se  of  the  Hat  variety. 

Lit/.mann,  who  ])uhlished  Miciiaelis'  posthumous  hook,  propo.sed  four  jjrades, 
accordiuf^  to  the  lenjz;tli  of  the  conju{>;ata  vera,  thus:  If  the  conjunata  vera  was  less' 
than  5.5  cm.,  ahsolute  contraction;  a  .second  decree,  from  5.5  to  7M  cm.,  a  third 
degree,  from  7.4  to  8.3  cm.,  and  a  fourth,  8.4  cm.  to  normal.  Schroder  propo.sed 
a  simj)ler  dixision.  As  tlie  shortest  conjugata  vera  which  would  ix'rmit  the 
delivery  of  a  normal-sized  child  tlirough  the  natural  ])a.s.sages  0.5  cm.  was  .set.  and 
pelves  smaller  than  these  were  called  (ihsuhdrlij  contracted.  If  the  conjugata  v<'ra 
was  from  0.5  to  9  cm.  long,  the  ]X'lvis  was  called  nUilivehj  contracte<l,  lK»cau.se  a 
living  child  could  he  gotten  through  in  a  large  projjortion  of  ca.ses,  and  a  mutilateil 
fetus  always.  A  third  grade  took  in  tho.se  with  a  conjugata  vera  from  9  cm. 
to  the  normal,  ajid  lahor  in  these  ca.ses  was  comi)licate(l  more  oft<'n  hy  errors 
of  mechanism  than  hy  spacial  disj)roportion  hetweeii  head  and  pelvis.  'i'he.s«» 
measurements  applied  to  flat  pelves.  In  generally  contracted  pelves,  since  there  is 
diminution  of  all  the  diameters  and  the  area  of  all  the  i)lanes  is  smaller.  0.5  cm.  is 
to  he  added  to  the  upper  limit  of  each  division. 

A  moment's  tlunight  will  show  how  artificial  and  futile  such,  or  an\',  division 
of  pelves  is,  hut  for  purposes  of  description  and  discu.ssion  some  standard  must 
be  used,  and  this  one  is  the  hest  of  all  yet  proposed.  The  size  of  the  child,  the 
hardness  and  moldahility  of  its  head,  the  presentation,  position,  and  attituih',  all 
make  the  jK'lvis  snudler  or  larger  as  far  as  the  (|uestion  of  spacial  relations  is  con- 
cerned. Add  to  this  the  difliculty  of  measuring  the  i)el\is  and  the  iiuiccuracies 
always  present,  and  it  hecomes  apparent  why  authors  vary  .so  much  in  their  esti- 
mate of  the  frequency  of  contracted  pelves  anil  in  the  division  into  ih'grees  or  gradt's

658  THE    PATHOLOGY    OF   LABOR 

which,  of  eourso,  increases  the  percentage,  and  the  others  are  from  out-maternities, 
in  Avhich  only  those  cases  exhibiting  ilehiy  in  hilior  are  accurately  measured,  or, 
practising  among  the  poor,  disclose  a  iiigher  })r()portion  of  deformities  than  the  whole 
community  would  show.  In  America  it  is  impossible  to  obtain  accurate  information 
of  the  frequency  of  pelvic  contraction.  In  American-born  women  it  is  undoubtedly 
rare,  many  practitioners  in  such  communities  meeting  hardly  one  or  two  in  a  life- 
time's practice.  ]\Iilder  degrc^es,  insufficient  to  provoke  serious  dystocia,  are  per- 
haps unobserved,  the  delay  in  lal)or  l)eing  ascribed  to  malpositions,  etc.  Among 
our  foreign-born  and  colored  population  high  grades  of  contraction  are  not  infre- 
quently observed,  but  here  again  statistics  furnished  by  the  obstetric  specialist 
and  the  clinic  or  the  hospital  are  useless,  because  the  difficult  labors  are  referred  to 
these  institutions  and  swell  the  percentages. 

Still  greater  uncertainty  exists  regarding  the  frequency  of  the  various  forms 
of  contracted  pelves.  It  seems  to  the  author  that  the  abnormal  pelvis  most  com- 
monly met  with  in  general  practice  is  a  mild  degree  of  the  funnel,  infantile,  or 
masculine  type.  In  consultations  on  obstructed  labor  the  generally  contracted 
has  been  more  frequently  encountered  than  the  flat  type.  Williams  noted  the 
latter  in  one-third  of  the  cases  in  white,  and  two-thirds  in  colored,  women.  In 
Germany  the  simple  flat  and  rachitic  flat  pelves  predominate,  but  even  there  the 
authors  are  not  agreed.     Osteomalacia  is  exceedingly  rare  in  America. 

THE  GENERALLY  CONTRACTED  PELVIS 

Other  names  for  this  type  of  anomaly  are:  Pelvis  sequabiliter  justominor 
(Stein);  pelvis  nimis  parva  (Deventer,  who  first  described  it).  Several  varieties 
are  to  be  considered:  The  simple,  equally  contracted  pelvis,  the  infantile,  the 
masculine,  and  the  dwarf.  Fig.  580  shows  an  equally  contracted  pelvis.  It  has 
beautiful  lines,  and  is  a  normal  pelvis  in  miniature.  This  pelvis  is  found  in  women 
of  small  stature  and  gracile,  never  in  large  women,  and  is  in  proportion  to  the  rest 
of  the  skeleton.  All  its  diameters  are  shortened,  though  rarely  is  the  relation  of  the 
conjugata  vera  to  the  others  absolutely  correct — usually  a  slight  flattening  exists. 
This  seems  to  indicate  that  perhaps  rickets  had  something  to  do  with  the  produc- 
tion of  the  general  hypoplasia.  Fig.  582  shows  a  justominor  pelvis  of  the  infantile 
or  juvenile  type.  The  inlet  presents  an  anteroposterior  oval;  the  sacrum  is  high 
and  long;  the  pelvic  inclination  marked.  Compare  it  with  Fig.  570,  a  child's 
pelvis.  This  pelvis  is  deep,  and  the  tuberosities  are  close  together,  giving  the 
excavation  a  funnel  shape.  A  woman  bearing  this  pelvis  will  have  narrow  hips, 
the  female  escutcheon  (the  hairy  portion  of  the  mons  veneris)  will  be  long,  narrow, 
and  sparsely  covered,  the  posterior  superior  spines  of  the  ilia  close  together,  the 
rhomboid  of  Michaelis  short  and  narrow,  the  labia  majora  small  and  undeveloped, 
the  same  being  true  of  the  breasts,  and  altogether  the  person  will  show  a  child's 
habitus.  Frigiditas  sexualis,  sterility  or  pregnancy  late  in  marriage,  and  other 
general  evidences  indicate  that  the  individual  was  not  completely  developed. 

If  the  bones  are  very  heavy  and  thick,  the  cavity  of  the  pelvis  may  be  en- 
croached upon  and  the  pelvis  may  partake  of  the  characters  of  the  male.  The 
sacrum  is  long  and  narrow,  the  arch  of  the  pubis  high,  the  sides  of  the  pelvis  close 
together,  and  the  inlet  even  an  anteroposterior  oval.  This  masculine  type  of  con- 
tracted pelvis  will  \)e  again  mentioned  under  funnel  pelves. 

Minor  degrees  of  general  pelvic  contraction  are  very  common — those  with  a 
conjugata  vera  between  9  and  10  cm.  are  moderately  rare,  while  those  below  9  cm. 
are  almost  always  combined  with  rachitis,  the  dwarf  pelves  alone  showing  a  true 
conjugate  of  7  cm.  or  less. 

Dwarf  pelves  are  very  rare  in  this  country.  Breus  and  Kolisko  distinguish  five  varieties 
of  dwarfs: 

1.  The  chondrodystrophic  dwarf,  the  result  of  achondroplasia  fcetalis,  which  formerly  was 


CONTRACTED    I'KLVIS 


(m9 


called  congenital  rickets.  The  developinent  of  the  long  l)onoft  is  hindered  l>v  pathologic  change 
in  the  epiphyseal  cartilages  f  Kaufman),  hut  the  head  and  chest  may  he  well  forme<l.  A  tendency 
to  ohesity  is  the  rule.  In  the  author's  case  the  ovaries  were  as  largi-  :ls  hen's  eggs  and  thnnigh 
and  tluough  cystic.  Is  it  possiMe  that  the  changes  in  this  organ  had  .something  to  d<i  with  the 
production  of  the  hony  deformiti<'s  and  the  ol)esity,  hoth  of  which  hegan  in  the  tenth  y«tir? 

The  i)elvi.s  of  such  a  dwarf  is  usually  very  small  ami  flat,  hut  signs  of  rachitis  are  alwent. 
The  flattening  is  due  to  insufHcient  development  of  the  iliac  ixjrtions  of  the  o««a  innominata 
(Hg.  -jSt).

3.  Cretins  often  have  dwarf  p<'lves.  They  are  characterizi'*!  by  genend  lack  of  deveIoi> 
ment  of  the  hones  and  delay  or  absence  of  o.ssification  of  many  of  the  epiphy-s*-}",  the  latter  jioint 
ilifTerentiating  them  from  true  dwarfs,  where  all  the  epinhy.xes  fail  to  fus«>,  even  very  hite  in  life. 
.\  cretins  pelvis  is  often  fiat,  with  thin  bones,  but  thickemsl  junctions  of  the  ossification  arejis; 
the  foramina  are  large,  and  the  siicrum  is  short  and  well  eurvetl.*  Other  evidences  of  insufficient 
thyroid  secretion  are  always  present.

The  Flat  Pelvis  t^Pelvis  Plana)  (Fig.  586). — This  is  a  pelvis  contracted  in  the 
anteroposterior  diameters,  and  many  authors  distinguish  two  kinds — the  simple  flat 
and  the  rachitic  flat.  The  writer  is  inclined  to  the  opinion  expressed  by  Ahlfeld  and 
Sellheim,  Breus  and  Kolisko,  that  the  so-called  "simple  flat  "  liclvis  is  really  rachitic 
in  origin.  The  absence  of  the  characteristic  rachitic  landmarks  on  the  pelvis  induced 
Betschler,  who  first  described  it,  and  IMichaelis  to  separate  it  from  those  of  known 
rickety  origin.  It  was  believed  that  the  carrying  of  heavy  weights  in  early  childhood 
or  putting  the  child  too  early  on  its  feet  caused  the  simple  flattening  of  the  pelvis, 
but  in  allprobability  the  cause,  if  not  due  to  rickets,  will  be  found  in  the  abnormal

tendency  of  growth  of  the  bones.  In  all  respects  save  two  the  simple  flat  pelvis 
looks  like  a  normal  one — the  sacrum  has  sunk  downward  and  forward,  giving  the 
inlet  a  broad,  kidney-shaped  outline,  and  the  pelvic  cavity  also  is  slightly  flattened. 
Schroder  says  this  pelvis  never  is  highly  contracted,  and  that  it  is  very  frequent, 
in  Germany.  There  is  no  widening  of  the  outlet,  and  the  distance  between  the  an- 
terosuperior  spines  bears  the  usual  relation  to  that  l^etween  the  crests.  Among 
the  large  number  of  flat  pelves  of  the  Northwestern  University  Medical  School, 
not  one  could  be  found  that  did  not  at  the  same  time  show  positive  evidences  of 
rachitis.     Flat  rachitic  pelves  are  not  rare  in  any  obstetric  museum  (Fig.  588).

are  smaller  and  tliiimer.  Rarely  the  bones  are  heavier.  The  ilia  tiare  outward 
and  are  flattened  so  that  the  distance  between  the  anterosuperior  spines  is  equal 
to,  or  greater  than,  the  distance  between  the  crests.  The  pelvic  inclination  is 
increased,  the  pubic  arch  broad,  the  angle  which  the  pubis  makes  with  the  inlet 
obtuse,  the  tuberosities  widely  separated,  and  the  acetabula  look  more  anteriorly 
than  is  normal.  This  peculiar  insertion  of  the  femora  gives  the  patient  a  remarkable 
gait,  the  feet  being  thrown  outward.  The  most  characteristic  changes  are  shown 
by  the  sacrum.  This  bone  is  forced  do^^^lward  into  the  pelvic  cavity;  the  con- 
cavity of  its  anterior  face  is  changed  in  both  directions,  so  that  it  becomes  flat,

and  in  advanced  cases  convex  from  side  to  side,  and  straight  from  alx)ve  downward, 
the  bodies  of  the  sacrum  protruding  from  between  the  wings,  and  the  sacrum  being 
bent  on  itself.  A  second,  or  false,  promontory  is  sometimes  found  below  the  true 
one  (Fig.  589).  Important  alterations  result  in  the  shape  and  size  of  the  pelvic 
canal,  most  prominent  of  which  is  the  flattening  of  the  inlet  from  before  backward. 
The  inlet  may  have  the  shape  of  a  kidney,  and  the  highest  degree  of  contraction 
may  exist  in  the  conjugata  vera.  The  transverse  and  ()bliqu(>  diam(H(M-s  may  be 
normal  or  even  larger.  The  true  pelvis  is  shallow,  the  outlet  usually  nmcli  enlarged 
(Fig.  590),  and  this  gives  labor  a  character  different  from  that  in  generally  con- 
tracted pelves.     In  the  latter,  because  the  pelvis  is  usually  uniformly  contracted

THE    PATHOLOGY    OF   LABOR 


The  characteristic  of  rachitis  is  the  flattening  of  the  pelvis,  and  the  experienced 
accoucheur  may  feel  this  at  once  by  grasping  the  hips  in  both  hands.  The  distance 
between  the  spines  of  the  ilia  is  usually  equal  to,  or  even  more  than,  that  between 
the  crests,  a  fact  Avhich  also  can  be  determined  by  palpation;  the  iliac  bones  flare 
out  and  appear  smaller  than  usual.  Baudelocque's  diameter  is  short,  running 
from  19  down  to  153^2  cm.,  and  when  scoliosis  exists  too,  the  external  oblique  diam- 
eters are  very  unequal,  but  seldom  is  there  a  difference  of  more  than  3  cm. 

On  internal  examination  will  be  noted  the  shallowness  of  the  pelvic  cavity; 
the  startling  prominence  of  the  sacral  promontory;   the  projection  of  the  ischiatic 


Fig.  594. — Mrs.  S.     A'-rat  of  Obliquely  Contracted  Rachitic  Pelvis. 


spines,  with  the  tense  sacrosciatic  ligaments;  the  possibility  of  palpating  the  linea 
terminalis  all  the  way,  and,  near  the  sacrum,  its  sharp  bend  forward;  the  presence 
of  an  exostosis  on  the  posterior  wall  of  the  pubis;  the  low  and  broad  pubic  arch, 
with  distant  tuberosities  of  the  ischia;  the  flat  or  even  convex  sacrum  when  pal- 
pated from  side  to  side  and  from  above  downward  (l)ut  here  one  may  note  that  the 
lower  third  of  the  bone  is  sharply  incurvetl) ;  and  the  reduced  conjugata  diagonalis. 
It  is  the  rule  to  deduct  2  cm.  from  the  length  of  the  diagonal  conjugate  to  obtain 
the  true  conjugate,  but  this  is  not  always  reliable.  If  the  angle  which  the  symphysis 
makes  with  the  inlet  is  very  obtuse;    if  the  pubis  is  very  high;    if  there  is  a  high

It  is  of  more  scientific  interest  than  practical  use  Tlic  information  it  gives  waa 
more  easily  obtainable  by  palpation. 

Finally,  the  course  of  the  lalx^r  will  often  disclose  the  nature  of  the  pelvic  con- 
traction, but  this  will  aj!;ain  be  discussed. 


THE  GENERALLY  CONTRACTED  FLAT  PELVIS 

When  rachitis  is  very  severe  and  prolonRed.  the  bony  growth  is  so  stunted  that 
the  pelvis  does  not  attain  to  n(jrmal  size.  Added  to  this  insufficient  devi-lopment 
are  the  deformations  of  the  pelvic  Ixjnes,  the  sinking;  down  of  the  sacrum,  etc., 
all  of  which  combine  to  produce  the  generally  contrai-ted  and  Hat  pelvis.     We  fin<l

the  smallest  jielves  in  this  class,  and  the  inlet  may  be  so  narrowed  that  it  will  hardly 
let  a  si.\  months'  fetus  pass  throuj^h  (Fiji.  •")0r)).  Rachitic  dwarfs  have  such  ix'lves, 
and  in  the  chondrody-strojihic  ilwarf  jx'lvis  of  the  author's  collection  much  flattening 
exists. 

OBLIQUELY  CONTRACTED  PELVES 

A  perfectly  symmetric  p(jlvi.-5  is  a  j^reat  rarity-  as  rare  as  a  perfect  face  or 
head.  One  oblique  diameter  is  always  a  little  larger  than  the  other.  When  this 
dilTerence  in  size  of  the  two  halves  of  the  inlet  is  marked,  we  speak  of  an  ol)li(|uely 
distorted  pelvis.  Several  varieties  are  to  be  described,  but  the  g«'neral  effects  of 
such  pelves  on  pregnancy  and  lal)or  are  ai)out  the  same. 

The  most  common  of  the  obliquely  contracted  p»'lves  is  the  result  of  .scoliosis 
of  the  vertebral  column,  and,  of  the  various  fornus  of  scoliasis.  the  rachitic  caus<*s 
the  most  marked  alterations  in  the  pelvis.  Much  deiM-nds  on  the  location  of  the 
curvature,  l)ecau.se  if  it  is  high  up.  compensation  takes  place  In-low.  and  the  effect 
on  the  pelvis  is  hardly  noticeable.  The  rotation  of  the  spinal  column  and  the 
torsion  of  the  vert(>bra»  are  distinguishable  in  the  sacrum  when  the  ilefonnity  is 
located  low  down.  Another  point  is  that  the  pelvic  asymmetry  may  cause  the 
scoliosis.      Fig.  590  shows  a  pelvis  with  simple  scoliosis,  probably  due  to  muscular

weakness.     Only  the  slight  flattening  indicates  the  possible  rachitic  origin.     IMild 
cases  of  such  scoliosis  are  not  uncommon,  but  very  rarely  do  they  give  rise  to

dystocia.  Fig.  597  shows  a  pelvis  with  a  larRo  lumon,  but  distorted  as  the  result 
of  a  scoliosis  due  to  infantile  rifrjit  spinal  paralysis.  It  Ls  ea«y  to  see  that  the  Ixjnes 
of  that  side  are  smaller  than  the  healthy  side. 

Fig.  598  shows  a  pronouncedly  rachitic  pelvis,  the  flattening  of  the  inlet,  the 
sinking  and  frontal  rotation  of  the  sacrum,  the  development  of  the  spines,  the 
flaring  of  the  ilia,  all  being  well  in  evidence.  Common  to  all  these  jM-lves  are  these 
points:  (I)  The  inlet  is  smaller  on  that  side  to  which  the  convexitv  of  the  lumbar 
scoliosis  points,  this  being  due  to  the  fact  that  the  sacrum  is  pushcij  over  onto  that 
side,  and,  the  trunk  pressure  being  greater  here,  the  sacrum  sinks  lower;  (2)  since 
the  trunk  pressure  comes  to  bear  on  one  wing  of  the  sacrum  more  than  on  the  other.

the  part  of  the  iione  which  sulTers  the  pressure  is  le!«s  well  develoix»<l,  the  foramina 
are  smaller  and  closer  together,  even  the  iliac  portion  of  the  sacro-iliac  joint  some- 
times taking  part  in  this  atrophy;  (3)  the  pelvis  is  tilted  so  that  the  more  contracted 
side  is  higher  than  the  larger  side;  this  is  due  to  the  fact  that  the  line  of  direction 
of  the  body  falls,  not  through  the  middle  line  of  the  .sacrum,  but  to  the  side,  away 
from  the  greatest  convcwity  of  the  scoliosis;  this  throws  the  weight  »)f  the  trunk 
almost  entirely  on  one  leg,  and,  therefore,  this  femur  is  forced  upward,  inward, 
and  l)ackward;  (4)  the  sciatic  notch  is  narrowed;  (5)  the  arcus  pubis  points  to  the 
contracted  side;  (6)  the  conjugata  vera  runs  ol)liquely  backward:  (7)  the  t»l>stetric 
transverse  diameter  is  always  shortened:  (S)  the  obli(|ue  diameters  are  very  un- 
equal; (9)  one  ischial  tuberosity  is  higher  than  the  other. 


670  THE    TATHOLOGY    OF   LABOR 

The  Coxalgic  Pelvis. — Disease  of  the  hip-joint  in  infancy  almost  always  leaves 
marked  pelvic  deformity,  but  rarely  does  sufficient  encroachment  on  the  lumen 
result  to  cause  serious  dystocia.  Fig.  600  shows  a  coxalgic  pelvis.  Since  the 
diseased  side  of  the  pelvis  is  painful,  the  patient  throws  all  her  weighton  the  well 
side,  and,  as  a  result,  the  head  of  the  femur  flattens  this  half  of  the  pelvis  and  the 
whole  pelvic  girdle  is  distorted.  The  bones  of  the  diseased  side  are  smaller  because 
of  atrophy  from  disuse  of  the  muscles,  and,  owing  to  irregular  muscular  and  liga- 
ment traction,  the  diseased  half  of  the  pelvis  is  enlarged  and  pulled  outward.  Since 
the  patient  tries  to  spare  herself  pain  by  keeping  that  leg  off  the  ground,  she  pulls 
up  the  diseased  side  of  the  pelvis,  which,  therefore,  is  higher  than  the  well  side — 
an  action  which  is  aided  by  the  crutch  worn  under  the  corresponding  axilla.  The 
asymmetry  of  the  pelvis  obtains  throughout  the  whole  pelvic  canal,  the  tuberosity 
of  the  ischium  of  the  affected  side  being  usually  druw-a.  upward  and  outward. 

Similar  pelvic  changes,  but  less  pronounced,  occur  with  tuberculosis  of  the 
knee,  amputation  of  the  thigh,  or  other  disturbance  of  function  of  one  limb.

contracted — is  that  due  to  disease  of  the  sacro-iliac  joint  and  the  neighboring  por- 
tions of  the  ilium  and  the  sacrum.  F.  C.  Naegele,  in  1839,  first  described  it,  having 
collected  37  cases,  but  it  was  mentioned  by  various  obstetric  writers  long  before 
this,  and  Naegele  found  one  in  an  Egyptian  mummy. 

All  the  findings  of  oblique  contraction,  and  those  due  to  exaggerated  pressure 
of  one  thigh,  are  present  in  this  pelvis,  and  since  one  wing  of  the  sacrum  is  often 
atrophic,  aplastic,  or  even  missing,  in  addition  to  the  distortion  actual  reduction  in 
the  size  of  half  of  the  pelvis  is  present,  and,  what  is  important  from  a  clinical  point 
of  view,  the  narrowing  of  the  pelvic  lumen  extends  down  to  the  very  outlet.  The 
innominate  bone  of  the  aff(H'ted  side  is  dislocated  upward  and  backward,  while  the 
pubic  joint  is  pushed  to  the  healthy  side.  The  linea  terminalis  of  the  healthy  side  is 
given  an  exaggerated  curve,  being  straightened  on  the  diseased  side.  In  nearly 
all  cases  a  firm  synostosis  is  found  in  the  affected  sacro-iliac  joint,  and  a  sharp 
polemic  was  waged  among  the  students  of  this  pelvis  as  to  whether  this  was  primary 
or  secondary.  Naegele  believed  that,  most  likely,  a  primary  congenital  deformity 
of  the  joint  existed,  and  he  did  not  deny  that  the  entire  change  could  be  due  to

not  SO  easy  to  decide  on  the  actual  pathology  of  it,  nor  on  the  degree  of  spacial 
contraction.  Attention  may  be  called  to  the  deformity  by  an  uneven,  limping 
gait,  a  scoliosis,  or  by  the  unequal  length  of  the  legs.  Scars  from  old  sinuses  point 
to  disease  of  the  hip  or  sacro-iliac  joints,  and  the  history  will  usually  show  some 
infantile  disease  or  injury.  Spinal  paralysis,  rachitis,  habit  scoliosis,  coxitis, 
gonitis,  amputation  of  the  leg,  and  spina  bifida,  have  been  the  causes  of  the  asjTii- 
metry  in  the  cases  which  came  under  my  observation,  and  it  was  possible  to  decide  in 
all  of  them  how  the  deformity  was  produced.  Fig.  003  is  a  photograph  from  a 
marked  case  of  coxitis,  and  Fig.  (305,  one  of  a  simple  scoliotic  pelvis.     A  rachitic

kyphoscoliotic  dwarf  pelvis  is  shown  in  Fig.  606  by  an  a:-ray  picture.  In  addition 
to  the  scoliosis  and  the  apparent  shortening  of  the  leg,  one  will  notice  the  hip  of  one 
side  higher  and  retroposed,  the  pubic  region  displaced  to  one  side,  and  the  hair-line 
oblique.  The  rhomboid  of  Alichaelis  is  asymmetric  or  tilted,  and  the  gluteal  fold 
lower  on  one  side.  Palpation  of  the  bones  confirms  the  above  findings,  and,  in 
addition,  discovers  that  the  ischial  tuberosity  of  one  side  is  higher  and  the  ramus  of 
the  pubis  has  a  different  direction  on  that  side.  Examining  first  Avith  one  hand  and 
then  with  the  other,  it  is  usually  possible  to  distinguish  the  fiat  linea  terminalis 
of  one  side  and  the  bowed  arc  on  the  other,  and  the  fact  that  one-half  of  the  pelvis

is  less  roomy.  External  measurements  from  corresponding  points  may  show  a 
discrepancy  between  the  two  sides,  but  it  is  almost  impossible  to  diagjiose  the  kind 
of  a  pelvis  from  them.  By  excluding  all  the  other  varieties  we  may  make  a  diag- 
nosis of  a  Xaegele  pelvis,  and  this  may  be  confirmed  by  finding  the  corresponding 
half  of  the  rhomboid  of  ^lichaelis  reduced  in  size,  the  spine  of  the  last  lumbar  verte- 
bra lying  close  to  the  posterosuperior  spine  of  the  ilium.  On  internal  examination 
the  corresponding  half  of  the  pelvis  is  very  small  and  the  encroachment  of  the 
ischium  on  the  lumen  persists  even  to  the  outlet.     Ankylosis  of  the  sacro-iliac  joints

may  be  palpated  by  the  fingers  per  vaginam  or  rectum  if  exostoses  and  pericapsular 
thickening  exist. 

After  the  fact  of  pelvic  distortion  has  been  discovered,  the  degree  of  pelvic  con- 
traction must  be  determined. 

A  few  cases  of  dislocation  of  the  ilium  upon  the  sacrum  are  on  record.  It  is 
easily  diagnosed  if  its  existence  is  suspected.  It  causes  persistent  backache, 
difficulty  in  locomotion,  and,  if  it  occurs  in  labor,  occasional  dystocia. 


TRANSVERSELY  CONTRACTED  PELVES 

It  has  been  generally  taught  that  contraction  of  the  superior  strait  is  the  most 
common  of  the  pelvic  deformities,  and  of  these,  anteroposterior  shortening  is  the 
most  important.  From  the  pathologist's  standpoint  this  may  be  true,  but  clin- 
ically the  justominor  and  transversely  contracted  pelves  are  more  commonly  found 
as  the  cause  of  dystocia.  Pelves  much  contracted  transversely  at  the  inlet  are 
very  rare. 


676 


THE    PATHOLOGY    OF   LABOR 


]\Iild  degrees  of  contraction  are  found  in  the  k^'photic,  the  infantile,  and  some 
varieties  of  high  assimilation  pelves.  Contraction  of  the  pelvic  outlet  is  found  in 
the  funnel  pelvis  and  those  of  the  masculine  type.

The  Robert  Pelvis. — Only  10  or  more  of  these,  the  classic  transversely  con- 
tracted pelvis  named  after  Robert,  who  in  1842  first  described  it,  are  in  existence. 
This  deformity  is  due  to  the  same  cause  which  produces  the  Xaegele  pelvis,  that

is,  an  ostoo-artliritis,  hut  acting  <>n  hr)th  sacro-iliac  joints.  Bolli  sides  of  the  jjelvic 
cavity  are  coniproinised,  and  the  inlet  luswuines  the  f(jnn  of  a  narrow  wedge  (Fig. 
G08).  The  narrowing;  of  the  jx-lvis  usually  extends  to  the  very  outlet,  and  in  one 
case  described  ijy  Breus  and  Kolisko  the  thstance  l>etween  the  spines  of  the  ischium 
was  only  2  cm. 

The  Kyphotic  Pelvis. — Fig.  (100  shows  a  iH'lvis  contracte<l  in  the  transverse 
diameter,  ami  possessing  also  s<jnie  of  the  characteristics  of  the  funnel  tyjx*.  It  is 
from  a  young  girl,  ossification  still  being  incomplete.  If  tln-kyphosisissituatedinthe 
upper  i)art  of  the  spinal  colunm,  a  compen.satory  lordosis  lower  down  restores  the 
line  of  direction  of  gravity  to  its  normal  position  in  the  statics  of  the  fxTson,  and, 
therefore,  the  ix-lvis  sulTers  little,  if  any.  change.  If,  as  in  Fig.  (ilO.  the  knuckle 
or  "gibbus"  is  in  the  lumi)ar 
spine,  marked  alteration  of  the 
pelvis  occurs.  The  sacrum  is, 
as  it  were,  drawn  upward  and 
out  of  the  ])elvis;  at  the  same 
time  it  rotates  on  a  transverse 
axis  so  as  to  throw  the  promon- 
tory up  and  back,  the  coccy.x 
for^vard  and  inward.  As  a  re- 
sult of  the  rotation  of  the  sac- 
rum the  innominate  bones  are 
rolled  around  the  sacral  articu- 
lar surfaces,  so  as  to  bring  the 
ischia  together  and  exaggerate 
the  forward  dip  of  the  crests, 
that  is,  increasing  pelvic  in- 
clination. This  action  is  pro- 
duced by  the  patient  throwing 
her  head  and  slioulders  back  to 
counteract  the  tendency  of  the 
bo(.ly  to  fall  forward  when  the 
bodies  of  the  vertebrie  soften 
and  break  down  under  the 
tubercular  caries  (Fig.  012). 

The  extreme  pelvic  in- 
clination of  these  pelves  is 
easily  understood.  The  pa- 
tient throws  the  lower  abdo- 
men forward  and  holds  the 
chest  high  and  the  shoulders 
backward.  Pendulous  belly  is 
more  marked  in  the.se  women 
than  in  all  others. 

If  the  caries  of  tlu*  vertelme  is  in  the  lowest  lumbar  or  in  the  first  sacral  verte- 
bra, the  upper  arm  of  the  knuckle  comes  to  lie  over  the  inlet,  nnifing  it  over — sfKtn- 
dylnlizemn,  as  Ilerrgott  called  it.  or  pelvis  ohtcctn,  a  Ix^ter  term,  offered  by  Fehling. 
While  the  inlet  may  be  large,  the  spinal  colunm  roofs  it  over  so  that  the  head  cannt)t 
gain  entrance  to  tin-  pelvic  canal. 

The  Funnel  Pelvis. — When  th«'  lumen  (tf  the  pelvis  grows  smaller  from  the 
inlet  to  the  outlet,  we  speak  of  funnel  pelvis.  Most  jx'lves  of  the  generally  con- 
tracted type  lu'long  in  this  class,  as  do  al.so  several  of  the  other  varieties  already 
ccmsidered — the  kyi)hotic,  the  Xaegeli^.  the  Robert's,  and  some  of  the  rachitic.

be  determined.  Fig.  613  shows  a  pelvis  normal  in  every  other  particular,  but  the 
sacrum  and  the  ischial  portions  of  the  innominates  converge  toward  the  outlet. 
Women  of  masculine  habitus,  who  have  large,  leonine  features,  hirsuties,  a  tendency 
to  firm  obesity,  and  who  are  often  sterile,  fretiucntly  have  heavy  bony  funnel  pelves. 
Infantilism  of  the  genitaha  sometimes  is  associated  with  funnel  pelvis.  Williams 
emphasizes  the  frequency  of  high  assimilation  as  a  cause  of  funnel  pelvis,  and  my 
own  observation  tends  to  confirm  this  view. 

High  degrees  of  funnel  pelvis  are  exceedingly  rare,  but  moderate  contraction 
of  the  outlet  is,  in  the  author's  experience,  a  pelvic  deformity  very  commonly  met. 
True  this  is  not  usually  recognized,  the  dystocia  being  ascribed  to  some  anomaly 
of  the  soft  parts  or  of  the  presentation  and  position,  the  size  of  the  fetus,  or  weak- 
ness of  the  powers  of  labor.  Without  doubt  many  of  the  forceps  operations  per- 
formed for  delay  in  the  second  stage  are  necessitated  by  contraction  of  the  bony 
pehdc  outlet. 

Diagnosis.- — Funnel  pelvis  of  the  kyphotic  type  is  easily  recognized — the  gibbus 
low  down  in  the  back  will  point  to  it.     Not  so  easy  is  the  recognition  of  the  mascu- 


Fio.  G13. — Funnel  Pelvis  (author's  collection). 


line  pelvis,  and  the  attendant  is  usually  only  apprised  of  the  latter's  existence  when 
a  stop  in  the  labor  occurs  with  the  head  low  down  in  the  pelvic  canal.  If  in  the 
routine  pregnancy  examination  the  accoucheur  will  take  care  to  palpate  the  descend- 
ing rami  of  the  pubis  as  in  Fig.  275,  p.  245,  and  measure  the  distance  between  the 
tuberosities,  as  in  Fig.  273,  such  surprises  will  come  to  him  very  seldom.  During 
lal)or,  if  the  palpation  of  the  side  walls  of  the  parturient  canal  does  not  indicate 
narrowing,  the  pelvimeter  used  as  in  Fig.  269  will  give  positive  information.  A 
masculine  pelvis  may  be  looked  for  if  the  patient  is  large,  with  a  tendency  to  firm 
adiposity,  with  large  k^onine  features,  and  hirsuties  of  the  face.  Often  such  women 
arc  married  late,  are  sterile  for  many  years,  have  frigiditas  sexualis,  early  meno- 
pause, and  often  develop  fibroids.  If  they  do  become  pregnant,  it  is  often  the  only 
reproductive  effort  (single  child  sterility),  for  which  reason  special  care  should  be 
exerted  to  preserve  the  child. 

Schauta  found  funnel  pelves  in  a))out  6  per  cent.,  Stocker  in  about  26  per  cent., 
and  Klien  in  24  per  cent.,  of  the  cases  examined.

sixth  spinal  vertebra  at  first,  hut  soon  the  twenty-fifth  and  twenty-n-venth  are  in- 
volved. If  the  iliac  hones  are  united  with  vertel)ra'  higher  up  in  tlie  i^puiiA  colunm, 
for  example,  the  twenty-fourth,  twenty-fifth,  and  twenty-sixth,  we  will  hnd  the  sa- 
crum lonji;  and  narrow,  and  the  first  sacral  vertehra  present  ins  the  characteristics  of

^vith  the  .sacrum,  and  such  a  pelvis  is  called  "upper  a.ssimilation  p<'lvis"-  upper, 
because  the  union  of  the  ilia  with  the  spinal  colunm  is  hinher  up  than  normal. 

If  the  union  of  the  ilia  witii  the  spinal  colunm  occurs  with  the  twenty-sixth, 
twenty-seventh,  and  twenty-ei,irhth  vertehrie,  we  find  a  short,  usually  broad  sacrum, 
and  the  last  lumhar  vertehra  having  many  of  the  characteristics  of  the  first  sacral.

The  last  lumhar,  the  twenty-fourth,  seems  to  be  assimilated  with  the  sacrum,  and 
such  a  jielvis  is  called  a  "lower  assimilation  })elvis" — lower,  IxH'ause  the  union  of 
the  ilia  with  the  spinal  column  is  lower  than  normal. 

In  many  instances  the  insertion  of  the  ilium  is  normal  on  one  side  and  higher  or 
lower  on  the  other,  asymmetric  assimilation  jx-lvis  ri'sulting.  Only  half  of  the  last 
lumhar  vertebra  then  goes  to  helj)  make  up  the  sacro-iliac  joint.  Scoliosis  is  a 
frequent  result  of  this  deformity.  Unless  one  has  the  whole  spinal  column  for 
study,  it  may  he  difhcult  to  tletermine  where  the  a.'vsimilation  occurrtHl.  Indeed, 
in  many  cases  it  is  not  easy  to  recognize  the  tieformity. 

Sometimes  the  coccyx  is  a.ssimilated  wMh  the  last  sjicral  vcrtcbne.  This  is 
of  little  i)ractical  importance.  Perhaps  fracture  of  the  ctM-cyx  is  more  common, 
and,  too,  since  assimilation  sometimes  cau.ses  funnel  and  transversely  contracted 
pelvis,  the  delay  in  labor  at  the  outlet  may  he  prolonged  by  the  abnormal  bt.ny 
formation,  which  latter,  too,  predisposes  to  fracture.

Fig.  597  (p.  668)  shows  an  asymmetric  assimilation  pelvis  from  the  author's 
collection.  It  was  combined  with  scoliosis.  Since  the  pelvic  lumen  is  not  seriously 
encroached  upon  in  the  assimilation  pelves,  much  practical  importance  is  usually 
not  attributed  to  this  deformity  by  most  authors.  I  am  convinced,  however,  that 
many  of  the  lesser  irregularities  of  labor,  such  as  occipitoposterior,  occipitosacral 
positions,  arrest  of  rotation  in  the  midplane,  deep  transverse  arrest,  extensive 
pelvic  floor  lacerations,  etc.,  are  due  to  the  irregular  shape  of  the  pelvic  canal  pro- 
duced by  these  peculiarities.     Transverse  contraction  can  be  so  pronounced  as  to

cause  real  dystocia,  and  if  the  child  is  large,  it  may  die  in  delivery  or  even  craniotomy 
may  be  required. 

Diagnosis. — It  may  be  possible  to  feel  six  sacral  vertebrae  in  exceptionally 
favorable  cases,  but  usually  the  diagnosis  of  assimilation  pelvis  on  the  living  is 
only  a  surmise.  When  distinct  narrowing  of  the  outlet  exists  and  signs  of  infan- 
tilism are  absent,  one  may  suspect  that  such  deformity  exists.  A  very  high  or 
double  promontory  with  normal  measurements  is  suggestive,  and  a  scoliosis  which 
has  no  other  apparent  cause  may  also  lead  one  to  think  of  assimilation.  The 
a:-ray  might  discover  it  (Fig.  618). 

Spondylolisthetic  Pelvis.— Kilian,  in  1854,  first  named  this  pelvis,  the  term 
being  derived  from  the  Greek,  which  means  a  sliding  of  the  vertebra.  F.  L.  Xeuge- 
bauer  is  entitled  to  the  greatest  credit  for  his  thorough  investigations,  and  many 
monographs  have  placed  the  subject  in  a  very  clear  light. 

The  essential  feature  of  this  pelvis  is  a  sliding  of  the  body  of  the  last  lumbar 
vertebra  over  the  first  sacral  and  into  the  pelvis,  carrying,  of  course,  the  spinal

column  -u-ith  it.  The  articular  processes  of  the  vertebra  and  sacrum  are  not  dis- 
located, the  slipping  of  the  body  of  the  former  being  permitted  by  a  stretching  or 
fracture  of  the  interarticular  processes.  The  interarticular  portion,  instead  of 
running  vertically  and  being  one-fourth  inch  long,  runs  horizontally  and  may  be  an 
inch  or  more  long.  The  last  lumbar  vertebra  thus  comes  to  be  much  elongated  from 
before  backward,  and  may  even  be  bent  over  the  sacrum  like  a  clamp. 

The  apposed  portions  of  the  tAvo  bones  are  compressed  and  often  spiostotic, 
with  the  formation  of  an  exostosis.  Severe  injury  is  probably  seldom  the  cause 
of  this  peculiar  deformity — more  likely  Neugebaucr's  explanation  applies.  There 
is  a  congenital  lack  of  fusion  of  the  ossification  areas  of  the  anterior  and  posterior 
ossification  centers  of  the  lateral  portions  of  the  vertebra,  a  spondylolysis  inter- 
articularis,  which  finding  is  not  rare  in  skeletons.  This  weak  spot  is  made  up  of 
cartilage,  is  a  pseudarthrosis,  or  is  held  together  by  fibrous  bands,  and,  under 
exterior  agencies,  injury,  or  carrying  heavy  loads,  gradually  yields  to  the  pressure 
of  the  trunk,  allowing  the  anterior  portion  of  the  vertebra,  especially  the  body, 


684 


THE    PATHOLOGY    OF    LABOR 


to  warp  over  the  sacrum  into  the  pelvis.  The  deformity  has  been  observed  in 
coal-heavers,  but  probably  here,  too,  some  congenital  deformity  of  the  bone  pre- 
existed or  it  should  l)e  more  common. 

On  the  pelvis,  spondylolisthesis  has  a  very  cU^forming  action:  (1)  The  in- 
clination of  the  pelvis  is  obliterated,  in  marked  cases  the  inlet  being  almost  hori- 
zontal; this  is  due  to  the  attempt  of  the  woman  to  keep  her  balance  by  throwing 
the  trunk  back,  and  thus  overcome  the  tendency  to  fall  forward;  (2)  the  lower 
lumbar  spine  projects  over  and  into  the  inlet, — pelvis  obtecta, — in  a  way  similar 
to  that  of  lumbosacral  kyphosis,  and  the  promontory  becomes  the  fourth,  third,

or  even  the  second  lumbar  vertebra;  (3)  the  available  true  conjugate  of  the  inlet 
may  be  reduced  to  even  5  cm. ;  (4)  the  sacrum  is  rotated  on  a  transverse  axis  in  a 
manner  similar  to  that  of  the  kyphotic  pelvis,  and  the  lower  tip  tends  to  approach 
the  pubis,  forming  a  funnel-shaped  canal;  (5)  the  innominate  bones,  responding 
to  the  rotation  of  the  sacrum  and  the  tug  of  the  muscles  and  iliofemoral  ligaments, 
converge  toward  the  outlet,  exaggerating  the  outlet  contraction;  (0)  the  distance 
between  the  posterosuperior  iliac  spines  is  increased;  (7)  the  arcus  pui)is  is  nar- 
rowed;   (8)  the  pelvic  joints  are  sometimes  loose. 

Diagnosis. — To  the  123  cases  collected  ])y  Williams  I  can  add  one  (Figs.  G21

the  deformity. 

A  study  of  the  accompanying  photographs  will  disclose  the  main  points  on 
which  a  diagnosis  may  be  based,  and  internal  examination  will  almost  always  render 
the  same  positive.  This  patient  gave  a  history  of  a  severe  fall  in  childhood,  fol- 
lowed by  a  long  confinement  to  bed.  The  following  features  are  to  be  noted:  (1) 
Short  squat  stature,  but  the  arms,  legs,  and  chest  are  of  normal  size;  (2)  the  pelvis 
seems  rotated  upward  (indicated  by  the  course  of  the  lines  which  have  been  painted 
over  the  ihac  crests),  and  the  ribs  nearly  rest  on  the  iliac  bones;    (3)  the  vulva  is

turned  upward  and  looks  forward;  (4)  the  posterosuperior  spines  are  far  apart, 
the  rhomboid  of  jMichaelis  is  broad,  runs  vertically,  and  the  spines  are  prominent, 
particularly  the  last  Imnbar,  which  stands  out  sharply,  as  is  seen  in  Fig.  623.  The 
extreme  compensatory  lordosis  is  well  sho^^^l,  and  the  head  too  is  thrown  back. 
This  patient  was  allowed  to  walk  on  a  long  strip  of  paper,  her  feet  having  been 
painted  with  rubber-stamp  ink,  and  Fig.  625  reproduces  her  footprints.  They 
show  clearly  the  short  steps  and  the  narrow  tread  (tight-rope  walker's  gait),  cor- 
responding •\\'ith  Xeugel)auer's  ichnographic  tracings  very  closely.

vertebra,  the  sharp  angle  could  easily  be  felt,  and  there  was  nothing  at  either  side 
of  the  body  of  this  vertebra — the  bifurcation  of  the  common  iliac  artery  was  dis- 
tinctly palpal^le  on  the  left  side,  but  not  on  the  right.  Von  Winckel  proved  that 
this  last  finding  was  unreliable,  being  found  also  in  kyphotic  pelves. 

The  Osteomalacic  Pelvis. — Part  of  the  general  affection,  osteomalacia,  which 
has  already  been  considered,  is  the  deformity  of  the  pelvis,  and,  from  the  ob- 
stetrician's point  of  view,  the  most  important.  As  the  result  of  the  action  of  the 
trunk  pressure,  the  pressure  of  the  heads  of  the  femora,  the  traction  of  the  muscles 
and  ligaments  on  the  softened  bones,  the  pelvis  is  crowded  together  in  an  astonish- 
ing manner.  Figs.  626  and  627  show  these  deformations,  and  description  is  unnec- 
essary. The  sinking  do^^-nward  and  forward  of  the  sacrum,  the  beak-like  distortion 
of  the  horizontal  pubic  rami  (due  to  the  inward  pressure  of  the  femora),  the  ap- 
proach of  the  tuberosities  of  the  ischia,  the  rolling  inward  of  the  iliac  crests,  must 
be  emphasized.  On  the  pelvic  lumen  this  invasion  from  three  sides  and  above  pro- 
duces very  decided  effects — indeed,  the  cavity  may  be  ahnost  obliterated. 


Fig.  62S. — Osteomalacic  Pelvis.     Highest  Degree. 


Fig.  G29. — Left  View  of  Fig.  62S. 


Labor  is  rendered  impossible  if  the  process  is  at  all  advanced,  but  if  it  occurs 
when  the  osteomalacia  is  in  the  florid  stage,  the  soft  bones  may  give  way  to  the  head 
advancing  under  the  influence  of  strong  pains,  and  dilate  enough  to  allow  the  child 
to  pass  through.  This  dilatation  of  the  pehnc  canal  has  been  foimd  in  17  to  30 
per  cent,  of  the  cases,  but  in  practice  it  is  best  not  to  depend  on  it. 

Diagnosis. — From  the  history  of  the  patient  one  will  learn  that  the  body  has 
gradually  gro^vTi  shorter,  w^th  complaint  of  rheumatoid  pains  in  the  back  antl  the 
pelvis,  difficult  and  painful  locomotion  (duck-gait),  contraction  of  the  adductor 
thigh  muscles,  muscular  tremljling,  paresis,  asthenia,  and  progressive  invalidism. 
Previous  labors  have  gro^^^l  successively  more  difficult.  Tenderness  is  found  over 
most  of  the  bones,  and  the  incurvations  of  the  spine,  the  ribs,  and  the  extremities 
are  usually  present  in  sufficient  degree  to  be  found.  On  the  pelvis  the  most  decided 
changes  are  discoverable,  the  most  notable  being  the  beaked  pubis,  the  narrow  pubic 
arch,  which  in  the  author's  case  hardly  permitted  two  fingers  to  pass;  the  sharply 
curved  sacrum  and  low  promontory.    All  the  external  measurements  are  diminished. 


688 


THE    PATHOLOGY    OF    LABOR 


In  the  differential  diagnosis  the  pseudo-ostcomalacic  rachitic  pelvis  need  be  men- 
tioned, but  the  history,  the  disease  appearing  in  childhood,  will  at  once  eliminate 
this.     Spondylolisthesis  is  also  easily  determined. 


DOUBLE  DISLOCATION  OF  THE  HIPS 
Congenital  dislocation  of  the  hips  is  not  a  very  rare  deformity,  and  only  recently 
have  the  efforts  of  the  orthopedists  been  successful  in  correcting  it.     When  such

a  child  begins  to  walk,  the  trunk  pressure  forces  the  whole  pelvis  onto  the  iliofemoral 
and  capsular  ligaments,  the  line  of  gravity  is  anteposed,  the  spinal  column  is  thrown

back  to  preserve  the  balance,  the  result  of  all  this  being  a  forward  tilting  of  the 
pelvic  girdle  and  increase  of  pelvic  inclination.  Since  the  transverse  pressure 
exerted  by  the  heads  of  the  femora  fails,  distinct  flattening  of  the  pelvis  results 
(Fig.  630).     The  outlet  is  very  large. 

Diagnosis. — In  the  accompanying  photographs  the  characteristic  appearance 
of  such  a  woman  is  to  be  seen.  The  high  trochanters,  the  broad  hips,  the  lordosis 
with  increased  pelvic  inclination,  the  folding  of  the  skin  at  the  hips,  the  loose-

jointed  gait — all  strike  the  eye  at  once.  On  internal  examination  the  shortening, 
if  there  is  any,  of  the  conjugata  vera  is  easily  determinable.  Labor  has  the  char- 
acteristics of  that  in  flat  pelves. 

For  the  sake  of  completion  may  be  mentioned  the  pehns  split  at  the  pubis, 
an  accompaniment  of  ectopic  bladder, — gastroschisis, — and  the  case  of  absence  of 
the  sacrum,  both  scientific  curiosities.

CHAPTER  LV 
CLINICAL  ASPECTS  OF  CONTRACTED  PELVES 

During  Pregnancy. — Certain  varieties  of  contracted  pelvis  may  interfere  with 
coitus,  for  example,  the  double  coxalgic,  with  ankylosis.  Very  large  pelves  allow 
the  uterus  to  sag  do^Mi  onto  the  pelvic  diaphragm,  and  such  women  show  increased 
pelvic  floor  projection.  It  has  seemed  to  me  that  they  suffer  larger  tears  in  labor 
and  are  liable  to  develop  prolapsus  uteri.  Retroversion  of  the  uterus  may  be 
maintained  bj'  an  overhanging  promontory,  and  if  pregnancy  supervenes,  an 
operation  may  be  needed  to  restore  the  uterus  to  its  place. 

As  a  rule,  it  is  later  in  pregnancy  that  the  effects  of  pelvic  ol:)struction  become 
apparent.  Since  there  is  no  room  in  the  pelvis  for  the  growing  uterus,  it  forces 
itself  upward,  the  abdomen  is  overcUst ended,  the  anterior  wall  stretches,  or  the 
recti  part  and  the  fundus  uteri  falls  forward,  the  condition  being  known  as  pendu- 
lous abdomen  (Fig.  353,  p.  399). 

If  the  muscles  retain  their  integrity,  the  uterus  is  forced  upward  against  the 
ribs  and  forms  here  a  high  plateau.  Another  effect  of  contracted  pelvis  is  the  con- 
ferring of  a  great  degree  of  mobility  on  the  uterus.  The  organ,  since  its  pelvic 
attachments  are  overstretched  and  it  lacks  the  support  of  the  side  walls  of  the  pelvis, 
is  free  to  sag  from  side  to  side  A\dth  every  turn  of  the  patient.  Some  women  com- 
plain much  of  this,  and  require  the  support  of  a  firm  binder.  From  the  same  causes 
the  position  and  presentation  of  the  fetus  change  readily  and  frequently.  The 
cephalic  pole  does  not  remain  so  constantly  over  the  inlet,  hence  when  labor  begins 
quite  often  the  child  is  found  in  an  unfavorable  attitude  and  presentation,  which, 
becoming  confirmed  by  the  uterine  contractions,  causes  serious  dystocia.  Vari- 
cose veins  of  the  \ailva  and  limbs,  especially  if  one  or  more  severe  operative  de- 
liveries have  preceded,  are  often  particularly  marked. 

During  Labor. — General  Considerations. — Labor  is  likely  to  be  a  little  prema- 
ture in  contracted  pelves  of  the  fiat  variety,  and  to  be  prolonged  in  those  of  the 
generally  contracted,  funnel,  and  masculine  types.  Reasons  for  this  I  cannot 
advance,  but  such  has  been  my  experience.  When  labor  has  frankly  declared 
itself  in  a  woman  with  contracted  pelvis  and  at  term,  it  early  becomes  evident  that 
the  process  is  not  going  as  it  should,  and  the  observant  accoucheur  soon  perceives 
that  it  is  not  alone  the  spacial  disproportion  which  causes  d^'stocia,  ])ut  many  other 
factors — abnormal  presentations,  positions,  attitude,  the  size  and  hardness  of  the 
fetal  head,  irregular  uterine  action,  premature  rupture  of  the  bag  of  waters,  etc. 

Abnormal  presentations — breech,  face,  brow,  shoulder — are  four  times  as 
frequent  with  contracted  pelvis,  Litzmann  having  found  the  cephalic  pole  pre- 
senting normally  in  only  84  per  cent,  of  his  cases  (usually  in  90  per  cent.).  The 
reason  for  this  is  that  the  head,  finding  the  cnit ranee  into  the  superior  strait 
blocked,  glides  off  into  one  iliac  fossa,  producing  an  obliquity  of  the  fetal  axis  to 
that  of  the  inlet.  It  is  now  easy  for  a  partial  or  even  a  complete  rotation  of  the 
fetal  ovoid  to  occur,  and  the  pains  coming  on,  the  child  is  locked  in  its  unfavorable 
position.  Prolapse  of  the  arm,  foot,  and  cord  are  also  much  more  common  in  all 
forms  of  pelvic  contraction,  but  particularly  in  the  flat  varieties.  The  reason  for 
this  is  that  the  head  does  not  lie  firmly  in  apposition  on  the  lower  uterine  segment, 
but  is  held  away  by  the  jutting  promontory  of  the  sacrum,  which  leaves  unfilled 

690 


CLINICAL    ASPECTS    OF    CONTRACTED    PELVES  691 

spaces  at  the  sides,  through  which  the  small  parts  easily  slip.  All  these  accidents 
are  commoner  in  multiparae  with  their  flaccid  and  flabb}'  uteri. 

A  great  deal  depends  on  the  size  and  moldability  of  the  fetal  head  and  of  the 
trunk.  If  the  bones  are  soft,  they  easily  give  themselves  to  the  shape  of  the  inlet, 
and  apparently  great  disproportion  may  thus  be  overcome.  If  the  child  is  small, 
the  pehas,  relatively,  may  not  be  at  all  contracted,  while  if  the  infant  is  large,  the 
contraction  of  the  pelvis  must  be  rated  higher. 

Of  prime  sigTiificance  in  all  labors  with  contracted  pelvis  is  the  action  of  the 
uterus.  Speaking  broadly,  the  strength  of  the  uterus  is  proportionate  to  the  amount 
of  work  required  of  it.  In  some  cases  the  uterus  acts  regularly  and  with  increasing 
power  as  it  finds  that  the  child  does  not  progress  through  the  birth-canal.  Within 
well-defined  limits  this  augmented  action  of  the  uterus  is  healthy  and  very  desirable, 
because  by  this  means  nature  often  overcomes  spacial  disproportion  between  the 
head  and  the  pelvis  which  no  one  would  have  thought  possible.  The  recurring 
pains  adjust,  compress,  mold,  and  propel  the  head  through  the  narrowed  canal 
in  a  fashion  that  the  finest  art  absolutely  fails  to  imitate.  Further,  good  pains 
dilate  the  cervix  and  prepare  the  soft  parts  for  the  passage  of  the  fetus.  Weak 
pains  are  a  most  unwelcome  complication  of  labor  in  contracted  pelvis.  They  may 
be  primary  or  secondary.  Primarily  weak  pains  frequently  accompany  generally 
contracted  pelvis  and  are  another  expression  of  the  infantilism  which  caused  it. 
Again,  other  causes  of  weak  pains  may  exist.  Weak  pains  from  exhaustion, 
tetanus,  or  infection  of  the  uterus  are  much  more  significant  and  correspondingly 
serious.  To  weak  uterine  action  are  often  added  weak  abdominal  muscles,  so 
common  with  pendulous  belly,  a  frequent  complication  of  contracted  pelvis.  If 
the  passage  is  not  too  markedly  contracted  and  the  child  is  of  moderate  size;  if 
the  presentation  and  position  are  good  and  the  pains  strong,  the  large  majority  of 
labors  wall  terminate  spontaneously  and  happil}'  for  both  mother  and  child.  Even 
experienced  accoucheurs  will  often  be  surprised  to  see  what  nature  can  accomplish 
if  properly  supported  and  not  interfered  with.  On  the  other  hand,  the  contraction 
of  the  pelvis  may  be  negligible,  as  far  as  spacial  disproportion  is  concerned,  but  it 
has  caused  an  abnormal  presentation — for  example,  brow  or  shoulder,  which  results 
in  perhaps  fatal  dystocia. 

The  First  Stage. — At  the  beginning  of  labor  the  head  is  high  up,  not  engaged, 
as  so  often  happens  in  healthy  primiparge  and  in  multiparae  with  strong  abdominal 
walls.  It  does  not  even  project  into  the  pelvis  with  a  large  segment,  but  floats 
high,  almost  out  of  reach  of  the  finger.  It  does  not  fit  the  lower  uterine  segment 
accurately,  hence  the  membranes  over  the  os  are  exposed  to  the  full  force  of  the 
uterine  contraction.  If  they  are  delicate,  they  burst  and  the  liquor  amnii  drains 
away;  if  they  are  tough,  they  are  stripped  off  the  lower  uterine  segment  and  pouch 
down  into  the  vagina  or  even  to  the  vulva,  stocking  shaped,  and  are  of  little  service 
as  a  fluid  dilating  wedge.  The  evil  consequences  of  early  rupture  of  the  sac  are: 
Loss  of  the  hydrostatic  cervical  dilator;  (2)  increased  danger  of  pressure  necrosis 
of  soft  parts  lying  between  head  and  pelvis;  (3)  increased  possibilities  of  prolapse 
of  cord,  arm,  and  feet;  (4)  infection  may  gain  entrance  to  uterine  cavity  and  cause 
physometra,  fetal  death,  and  sepsis.  If  the  memljranes  rupture  before  complete 
dilatation  has  been  secured,  the  lower  uterine  segment  and  cervix  collapse,  and  it 
requires  prolonged  effort  on  the  part  of  the  uterus  to  open  the  passage  again,  ^'on 
Herff 's  experience  must  have  been  contrary  to  that  of  most  observers,  for  he  finds 
that  rupture  of  the  bag  of  waters  in  contracted  pelvis  is  not  an  event  to  be  feared; 
that  the  dilatation  progresses  just  as  satisfactorily  as  before,  or  often  better. 

True,  the  pains  may  be  stronger  after  the  waters  have  drainetl  away,  but  ex- 
perienced accoucheurs  will  find  it  hard  to  admit  that  the  head  makes  as  efficient 
and  as  safe  a  cervical  dilator  as  the  bag  of  waters,  or  that  the  mother  and  child  are 
not  in  more  danger  after  the  sac  has  been  opened,  and  they  will  be  loath  to  dispense

or  operative  deliver3\ 

IVIany  differences  are  observed  in  the  way  the  lower  uterine  segment  is  formed 
and  the  cervix  dilated  in  cases  of  obstructed  labor.  In  a  healthy  primipara  the 
usual  mechanism  occurs,  but  in  a  multipara,  especially  if  she  has  had  several 
difficult  labore,  the  contraction  ring  ascends  very  early,  the  lower  uterine  segment 
quickly  forms  under  the  influence  of  the  pains,  and  the  os  soon  dilates.  Now, 
unless  the  head  quickly  passes  into  and  through  the  pelvis,  the  expanded  parturient 
canal  will  give  way  and  allow  the  fetus  to  escape  into  the  peritoneal  cavity.  If  the 
cervix  is  tough,  it  may  long  resist  the  action  of  the  uterus  and  require  the  inter- 
vention of  art.  Sometimes  the  cervix  is  compressed  between  the  head  and  the  pelvis. 
The  part  below  the  area  of  compression  then  may  become  edematous  and  even 
slough  off.  Particularly  the  anterior  lip,  in  flat  pelves  with  pendulous  belly,  is 
liable  to  be  caught  between  the  head  and  the  pubis,  becoming  enormously  swollen 
(sometimes  to  the  size  of  one's  wrist),  suggillated,  even  necrotic,  leaving  cervico- 
vesical  fistula.  Previous  deep  lacerations  of  the  cervix  and  of  the  lower  uterine 
segment  predispose  to  fresh  rupture.  Dilatation  of  an  old,  much-lacerated  cervix 
is  usually  rapid  unless  the  scars  are  very  extensive. 

The  Second  Stage. — Up  to  this  point  labor  in  nearly  all  forms  of  contracted 
pelvis  is  the  same.  When  the  head  is  to  pass  through  the  inlet,  different  mechanisms 
are  developed,  and  these  will  be  considered  separately  later.  Certain  general 
features  are  common  to  all  obstructed  labors,  and  they  may  be  divided  into  two 
groups:  first,  the  absolutely  impossible  labor,  where  the  disproportion  is  so  great 
that  the  child  cannot  pass,  and,  second,  the  labors  where  the  child  can  pass,  but 
it  requires  prolonged  effort  on  the  part  of  nature,  without  or  with  the  help  of  art. 

If  the  head  is  arrested,  the  uterus  is  stimulated  to  redoubled  vigor,  the  pains 
become  stronger  and  stronger,  the  intervals  shorter,  but  no  advancement  is  per- 
ceptible. A  large  caput  succedaneum  replaces  the  bag  of  waters,  and  the  scalp 
may  be  visible  at  the  vulva  when  the  head  has  not  yet  passed  the  inlet.  The  vagina 
becomes  hot,  swollen,  blue,  and  dry,  the  vulva  dark  blue  and  edematous,  often 
with  small  suggillations,  and  in  much  neglected  cases  gangrenous.  The  child  dies 
because  the  violently  acting  uterus  cuts  off  its  oxygen  supply,  and  sometimes  also 
from  cerebral  injury  or  hemorrhage,  the  result  of  nature's  attempt  to  crowd  the 
head  through  a  passage  too  small  for  it.  If  aid  is  not  rendered,  the  woman  in- 
evitably dies  and  death  occurs  from  rupture  of  the  uterus,  with  intraperitoneal 
hemorrhage  or  shock,  from  sepsis,  or  exhaustion.  (For  the  symptoms  of  rupture 
of  the  uterus  the  reader  is  referred  to  Chapter  LIX.)  Infection  during  prolonged 
laljor  may  be  autogenous  or  exogenous.  In  the  vast  majority  of  cases  the  phy- 
sician introduces  the  infection  from  the  vulva,  or  from  without  entirely,  or  bj^  re- 
peated examinations  inoculates  the  patient  with  the  bacteria  normally  present  in 
the  vagina,  the  frequency  of  the  various  modes  being,  in  the  author's  opinion,  in 
the  order  given.  In  a  small  percentage  of  the  cases  the  bacteria  wander  upward 
from  the  vagina  through  the  opened  membranes  into  the  uterine  cavity.  In 
either  event  the  woman  develops  fever,  the  first  effect  of  which  is  to  stimulate  the 
pains,  but  soon  the  uterus  is  paralyzed,  with  or  without  the  formation  of  gas  in  its 
cavity  (physometra).  Women  in  labor  stand  infection  not  at  all  well,  and  the 
temperature  and  pulse  rapidly  mount  high,  while  delirium,  subicterus,  and  pros- 
tration quickly  follow.  There  is  a  foul  discharge  from  the  vagina,  and  the  vulva 
is  swollen,  reddened,  and  superficially  necrotic  in  places.  Acute  dilatation  of  the 
heart  is  a  not  rare  termination  of  too  prolonged  labor. 

Exhaustion  is  an  infrequent  cause  of  death,  but  without  doubt  it  will  explain 
many  cases  of  shock  and  of  gradual,  uncontrollable  asthenia  terminating  fatally 
after  operative  delivery.  The  operation  may  have  Ijeen  quick  and  skilful,  Avithout 
undue  hemorrhage,  and  with  little  anesthetic,  but  the  woman  does  not  rally,  the

pulse  mounts  higher  and  higher,  the  vital  powers  slowly  sink,  and  in  from  four  to 
twenty-four  hours  death  supervenes  in  quiet  coma.  In  the  differential  diagnosis 
internal  hemorrhage,  uremia,  and  shock  from  injury  are  to  be  considered. 

If  the  disproportion  is  not  absolute,  nature  often  accomplishes  the  deliverj% 
and  even  the  experienced  obstetrician  must  marvel  when  he  sees  all  his  precon- 
ceived notions  set  at  naught. 

At  first  the  head  is  high  up,  separated  from  the  bony  inlet  by  a  pad  of  thick 
cervix,  the  bases  of  the  broad  ligaments,  the  bladder,  and  the  pelvic  connective 
tissue  in  general.  After  the  uterus  has  been  in  action  for  a  while  all  these  structures 
except  the  base  of  the  bladder  are  dra\\'n  upward  with  the  retraction  of  the  lower 
uterine  segment  out  of  the  pelvis,  thus  allowing  the  head  to  apply  itself  to  the  inlet. 
If  one  examines  the  w^oman  now  during  a  pain,  peculiar  phenomena  are  observed. 
The  head  flexes  and  deflexes,  and  sometimes  rotates  on  its  transverse  axis,  or  even 
in  a  horizontal  plane,  and  one  feels  the  large  fontanel  advance,  recede,  turn  from 
behind  forward,  and  the  head  rolls  on  either  shoulder.     It  is  important  for  the 


Fig.  635. — Head  After  Four  Days'  L.vbor  ix  a  Generally  Contracted  and  Flat  Pelvis.

accoucheur  to  study  these  motions  with  great  care,  because  thej'  are  the  evidences 
of  the  intended  mechanisms  of  the  head,  that  is,  that  manner  in  which  the  head  is 
to  overcome  the  resistances  of  the  passage.  Nature  seems  to  be  fitting  the  head  to 
the  pelvis  as  a  key  is  fitted  to  the  wards  of  a  lock,  until  a  combination  is  secured 
which  will  best  allow  the  head  to  pass. 

Now  the  process  of  molding  or  configuration  begins,  and  the  general  intra- 
uterine pressure,  together  with  the  fetal  axis  pressure,  gradually  forces  the  head 
through  the  narrowed  superior  strait.  Owing  to  the  nature  of  things  the  head 
cannot  be  reduced  in  size  by  compression,  and  only  a  minute  quantity  of  cerebro- 
spinal fluid  can  escape  through  the  foramen  magnum  into  the  spinal  canal — not 
enough  appreciably  to  affect  the  size  of  the  head.  Now,  owing  to  the  softness  of 
the  cranial  bones  and  their  movability  on  each  other  at  the  sutures,  the  head  is 
capable  of  being  changed  in  form  so  that  it  accommodates  itself  to  the  shape  of 
the  superior  strait.  That  parietal  bone  which  first  meets  with  resistance  is  pressed 
under  the  other,  and  the  plate  of  the  occipital  bone  lies  under  the  two  parietals. 


694  THE    PATHOLOGY    OF   LABOR 

The  overlapping  may  l)e  so  marked  that  the  dura  mater  l^egins  to  strip  off,  and  a  row 
of  minute  hemorrhages  will  be  found  on  either  side  of  the  longitutlinal  sinus.  Fig. 
635  shows  the  head  of  a  child  spontaneously  delivered  after  four  days'  labor.  This 
length  of  time  is  very  seldom  required  for  the  process;  indeed,  nowadays  such  cases 
are  not  allowed  to  take  so  long,  but  interference  is  thought  necessary  after  giving 
the  natural  powers  reasonable  opportunity  to  show  how  much  thc^y  can  accomplish. 
From  four  to  ten  hours  of  good  strong  pains  will  almost  always  suffice  for  the  test, 
but  even  here  great  watchfulness  is  indicated  lest  mother  or  babe  suffers  harm  from 
the  experiment. 

As  soon  as  the  head  has  been  molded  so  that  it  is  ready  to  pass  through  the 
inlet  the  pains  assume  an  expulsive  character — the  parturient  bears  down,  the 
head  drops  into  the  excavation,  and  the  occiput  begins  to  rotate  to  the  front. 

Three  signs  indicate  that  the  head  is  descending:  (1)  The  patient  begins  to 
bear  down;  (2)  feces  are  discharged,  or  the  woman  expresses  a  desire  to  go  to  stool; 
(3)  cramps  of  the  muscles  of  the  legs  occur — usually  the  left  leg  in  left  occiput 
positions  and  vice  versa.  The  first  two  symptoms  are  due  to  the  pressure  of  the 
head  upon  the  rectmn;  the  last  one,  to  irritation  of  the  sacral  plexus  by  contact  of 
the  advancing  head.  In  flat  pelves,  in  which  the  resistance  is  met  only  at  the  inlet, 
this  part  of  the  labor  is  completed  with  surprising  quickness.  In  multiparse  one 
or  two  powerful  expulsive  pains  procure  anterior  rotation  and  the  Ijirth  of  the  head; 
in  primiparse  the  soft  parts  have  to  be  overcome,  and  this  requires  the  usual  time. 
The  head  may  be  given  a  shape  different  from  that  acquired  in  the  passage  of  the 
inlet  by  the  molding  caused  by  the  pelvic  floor.  If  the  pelvis  is  generally  contracted, 
the  resistance  continues  all  the  way  to  the  outlet,  and  labor  is  unduly  prolonged  and 
tedious.  In  addition  the  uterine  action  in  this  class  of  pelvis  is  often  weak,  the 
uterus  partaking  of  the  general  hypoplasia.  Women  with  funnel  and  masculine 
pelves  are  also  prone  to  uterine  inertia.  Occipitoposterior  positions,  imperfect 
dilatation  of  the  cervix,  and  strictura  uteri  (hour-glass  contraction)  are  also  more 
common  in  them. 

After  the  head  is  delivered  the  main  difficulty  is  overcome,  but  if  the  child  has 
broad  shoulders,  they  may  cause  much  trouble,  especially  in  the  generally  and 
transversely  contracted  pelves.  Many  an  infant  has  been  lost  during  the  pro- 
longed attempts  to  deliver  impacted  shoulders.  At  any  point  the  uterus  may  give 
out  and  labor  comes  to  a  standstill,  requiring  the  assistance  of  art.  It  is  as  often 
the  nervous  system  of  the  woman  or  the  condition  of  the  baby  which  demands  inter- 
ference as  the  uterus  proving  default. 

The  third  stage  does  not  present  any  conditions  which  are  peculiar.  Post- 
partum hemorrhage  is  rare  if  the  pains  have  been  good,  but  if  the  delivery  has  been 
operative,  lacerations  and  bleeding  must  be  expected. 


CHAPTER  LVI 

MECHANISM  OF  LABOR  IN  FLAT  PELVES 

An  experienced  accoucheur  can  diagnose  the  nature  of  the  pelvis  by  observing 
the  mechanism  with  which  the  head  passes  througli  it.  Many  of  its  motions  are 
characteristic  of  flat  and  of  generally  contracted  types.  In  flat  pelves  abnormalities 
of  position  and  presentation  are  very  common.  Owing  to  the  jutting  forward  of 
the  promontory,  the  head  may  not  enter  the  pelvis  and,  therefore,  slips  off  to  one 
side,  which  often  allows  the  cord  to  prolapse  in  the  free  space  thus  provided.     The

head  tries  to  enter  the  pelvis  flexed,  as  in  the  usual  mechanism  of  labor,  but  the 
biparietal  diameter  is  too  large  to  pass  through  the  conjugata  vera,  the  diameter 
of  greatest  contraction.  As  a  result  the  head  slides  off  to  the  side,  the  bitemporal, 
a  smaller  diameter,  comes  to  lie  in  the  conjugata  vera,  while  the  biparietal  lies 
in  the  larger  space  opposite  the  sacro-iliac  joint.  As  soon  as  the  head  sinks  the 
forehead  descends,  because  the  resistance  offered  the  occiput  is  greater— deflexion, 
instead  of  flexion,  the  first  movement,  occurs.  Owing  to  the  long  transverse  and 
short  sagittal  diameters  of  the  inlet  the  head  seeks  the  position  which  Avill  easiest

THE    PATHOLOGY   OF   LABOR 


allow  it  to  advance — that  is,  the  sagittal  diameter  of  the  head  will  lie  in  the  trans- 
verse of  the  pelvis. 

A  thirtl  and  most  important  abnormality  of  the  mechanism  is  the  almost 
constant  lateroflexion  of  the  head,  that  is,  the  parietal  bone  is  inclined  on  one  or  the 
other  shoulder,  or,  in  other  words,  the  head  enters  the  pelvis  in  exaggerated  asj'n- 
clitism.  This  is  called  parietal  bone  presentation.  Normally,  although  some 
authorities  deny  it,  the  head  often  enters  the  pelvis  with  slight  anterior  asynclitism, 
that  is,  obliquity  of  Naegele.  In  flat  contracted  pelves  this  is  exaggerated,  and 
sometimes  the  lateroflexion  is  so  great  that  the  anterior  ear  is  palpable  behind  the 
pubis — ear  presentation.  In  the  subsequent  course  of  labor  the  posterior  parietal 
bone  rolls  over  the  promontory  into  the  pelvis,  the  anterior  bone  forming  a  sort

of  sliding  fulcrum  on  the  posterior  wall  of  the  pubis.  The  amount  of  molding  of 
the  cranial  bones  needed  to  allow  the  descent  of  the  head  according  to  this  mechan- 
ism depends  on  the  size  and  hardness  of  the  head  and  the  roominess  of  the  inlet, 
and  the  time  required  depends  also  on  these  factors  plus  the  strength  of  the  uterine 
contractions.  The  process  may  be  completed  in  a  few  hours,  or  may  last  over  a 
day  (Figs.  636,  637,  and  638).  That  part  of  the  head  which  rubs  over  the  promon- 
tory often  shows  a  pressure  mark — a  red  streak.  In  right  positions  the  red  mark 
(in  bad  cases,  real  pressure  necrosis)  lies  over  the  right  parietal  bone,  parallel  with 
the  coronary  suture;  in  left  positions,  in  a  corresponding  location  over  the  left 
parietal  bone.  The  configuration  of  the  head  is  sometimes  remarkable.  In  one 
of  the  author's  cases  the  head,  viewed  from  above,  had  t;h<'  shape  of  a  kidney,  and 
was  almost  a  mold  of  the  pelvic  inlet.     If  the  head  remains  long  in  the  pelvis  after 


MECHANISM    OF    LABOR    IN    FLAT    PELVES 


697 


having  passed  the  superior  strait,  it  acquires  another  shape  from  the  secondary 
mokhng  produced  by  the  pelvic  floor. 

As  soon  as  the  greatest  periphery  of  the  head  has  passed  the  region  of  the  inlet, 
or  even  just  as  it  is  about  to  pass,  the  occiput  sinks,  the  large  fontanel  ascends, 
descent  of  the  head  takes  place,  and,  as  a  rule,  anterior  rotation  follows  at  once. 
The  head  undergoes  a  complicated  movement,  consisting  of  descent,  flexion  (the 
chin  on  the  sternum),  laterodcflexion,  that  is,  the  synclitic  movement  and  anterior 
rotation  of  the  occiput  all  simultaneously.  Now  the  mechanism  is  as  usual — 
flexion,  descent,  extension,  external  restitution.  Even  in  primiparae  a  few  pains 
often  accomplish  the  delivery;   in  multiparae  it  is  usually  done  wdth  one  or  two. 

Findings. — Abdominally,  one  may  determine  the  deflexion  of  the  head  by 
noting  the  straightening  of  the  fetal  spine.     The  lateroflexion  at  the  neck  may

Some  lateroflexion  of  head  persists  even  as  late  as  this. 


also  be  felt.  On  internal  examination  the  sagittal  suture  lies  in  the  transverse 
diameter,  but  very  close  to  the  sacrum;  the  small  is  on  the  same  level  as  the  large 
fontanel,  sometimes  even  higher,  so  that  the  brow  comes  doA\Ti;  the  sutures  are 
at  first  plainly  felt,  because  the  cranial  bones  overlap  so  strongly,  but  later  in  labor 
the  caput  succedaneum  obliterates  the  lines  (Fig.  639). 

Another  mechanism,  and  an  important  variation,  is  the  posterior  parietal 
bone  presentation  (Fig.  640).  Here  the  head  is  inclined  on  the  anterior  shoulder; 
the  posterior  parietal  bone  occupies  the  vault  of  the  pelvis, — posterior  asynclitism, 
— and  if  the  lateroflexion  is  very  decided,  the  posterior  ear  may  be  palpable  in 
front  of  the  promontory — "posterior  ear  presentation."  The  mechanism  here  is 
the  reverse  of  that  just  considered.  The  posterior  parietal  stems  on  the  promontor}' 
and  the  anterior  rolls  down  from  behind  the  pubis  into  the  pelvis.

which  the  shoulder  makes  with  tlie  head  just  above  the  pubis,  and  often  the  round

MECHANISM    OF   LABOR    IN    FLAT    PELVES 


699 


Internally,  the  sagittal  suture  runs  just  behind  the  pubis,  usually  transverse,  or 
the  least  bit  obliquely,  the  small  and  large  fontanels  on  a  level  or  the  small  one  up 
high,  out  of  reach,  and,  by  passing  the  fingers  well  up  above  the  promontory,  the 
ear  is  sometimes  to  be  felt.  As  the  head  descends  the  sagittal  suture  leaves  the 
pubis  and  comes  to  lie  nearer  the  sacrum,  but  then  descent  and  anterior  rotation  of 
the  occiput  luring  the  sagittal  suture  into  an  oblique.  Sometimes  the  lateroflexion 
is  kept  up  until  the  head  escapes,  and  then  the  occiput  is  likely  to  remain  in  the 
obUque  and  the  nape  of  the  neck  stems,  not  directly  behind  the  pubis,  but  behind 
one  ramus,  and  the  head  is  delivered  in  the  oblique.  Use  may  be  made  of  this  fact 
in  the  conduct  of  such  a  labor,  and  the  processes  of  nature  imitated  by  art. 

Why  the  head  enters  the  pelvis  in  one  or  the  other  of  these  attitudes  is  not 
known.  Probably  pendulous  abdomen  will  explain  the  anterior  parietal  variety, 
but  I  have  seen  the  posterior  parietal  present,  and  pendulous  belly  was  also  a 
complication.  A  high  sacrum  might  predispose  to  the  anterior  parietal,  especially 
if  there  is  a  double  promontory.  Litzmann  says  that  the  anterior  parietal  bone 
presentation  is  three  times  more  frequent  than  the  posterior.  In  general  the  more 
contracted  the  pelvis,  the  closer  the 
sagittal  suture  runs  to  either  promon- 
tory or  the  pubis. 

Labor  is  much  more  difficult  and 
more  often  impossible  in  posterior 
parietal  bone  presentation,  since  in 
the  latter  the  child  is  bent  almost  to 
a  right  angle  at  the  neck.  The  uterus 
acts  at  a  great  disadvantage  also,  and 
is  liable  to  excessive  thinning  on  the 
posterior  wall,  a  point  of  utmost  prac- 
tical importance,  since  here  sponta- 
neous rupture  may  occur,  and  the 
greatest  danger  from  traumatism  lies. 


MECHANISM    OF   LABOR    IN    GENER- 
ALLY CONTRACTED  PELVES 

Labor  in  this  class  of  pelves  also 
bears  marked  characteristics.  Since 
the  head  fits  the  inlet  well,  abnormal 
attitudes,  presentations,  and  positions 
are  not  so  frequent  as  in  flat  pelves. 
Prolapse  of  the  cord  is  rare  because  the 
head  fits  the  lower  uterine  segment  ac- 
curately. Early  in  labor  one  notes  that 
the  head  lies  in  flexion,  and  as  soon  as 


Fia.  041. — Head  About  to   Enter  a  Generally  Con- 
tracted Pelvis.     Partla.l  Flexion. 


descent  begins  this  flexion  becomes  ex- 
treme, the  small  fontanel  being  the  first  reached  by  the  finger,  and  the  sagittal  suture 
lying  in  an  oblique  diameter  of  the  pelvis  and  running  almost  perpendicularly.  After 
labor  has  been  in  progress  for  some  time  and  molding  is  advanced,  the  small  fontanel 
lies  almost  in  the  center  of  the  pelvis,  and  is  covered  by  the  caput  succedaneum.  The 
extreme  flexion  is  due  to  an  exaggeration  of  the  same  mechanism  which  produces 
flexion  in  normal  labor — the  sincipital  end  of  the  lever,  being  longer,  meets  with 
greater  resistance  and  rises  higher.  Nature  finds  this  the  easiest  way  to  force  a  head 
through  a  pelvis  contracted  in  all  diameters.  Generally  contracted  pelves,  unlike  flat 
ones,  have  the  narrowing  all  the  way  down,  and,  therefore,  progress  is  not  rapid 
after  the  inlet  has  been  passed,  but  the  head  has  to  bore  its  way  slowly  do's\Ti  (Figs. 
641,  642,  and  643).

THE    PATHOLOGY    OF    LABOR 


Fig.  642. — Head    Entering    a  Generally   Contracted 
Pelvis.     Flexion  Marked. 


Pressure  marks  are  unusual  be- 
cause the  resistances  met  are  Inroad,  not 
sharp,  as  in  flat  pelvis,  and  when  they 
are  present,  owing  to  the  flexion  of  the 
head,  are  found  on  the  frontal  bone, 
which  lay  against  the  promontory. 
Excessive  length  of  the  occipitofrontal 
diameter  characterizes  the  molding  in 
these  cases,  the  occiput  is  peaked,  the 
forehead  and  face  are  flattened,  the 
neck  is  almost  in  a  line  with  the  back 
of  the  head,  and  the  chin  is  buried  in 
the  chest.  Lateral  asymmetry  is  also 
marked.  Extreme  overlapping  of  the 
bones  and  minute  cracks  and  fissures 
of  the  parietals  or  frontals  are  very 
common. 

Labor  in  this  form  of  pelvis  is 
usually  very  slow  and  tedious.  The 
uterus,  partaking  of  the  general  hypo- 
plasia, acts  poorly,  and  often  gives  out 
before  the  head  has  passed  all  the  nar- 
row straits,  instrumental  interference 
being  required.  This  is  especially 
dangerous  to  both   mother  and  babe 

because  of  the  inevitable  injuries  to  the  soft  parts  and  the  great  compression 

of  the  child's  brain.     If  the  delivery  is  spontaneous,  laceration  of  the  perineum 

seldom  occurs,  because  the  head  is  so 

long  drawn  out. 

The  diagnosis  of  labor  with  gener- 
ally contracted  pelvis  is  usually  easy. 

Abdominally,  the  extreme  flexion  is  in- 
dicated  by  the  high  forehead,  easily 

palpable  over  one  ramus  pubis,  and 

the  deep  occiput,  usualh'  not  palpable, 

even  when  the  hand  is  pressed  deeply 

into  the  groin.     Vaginally,  the  small 

fontanel  lying  almost  in  the  axis  of  the 

pelvis  and  the  vertical  position  of  the 

sagittal   suture    disclose   the    extreme 

flexion  so  characteristic  of  this  form  of 

labor. 

Labor  in   pelves,   both  generally 

contracted  and  flat,  partakes  more  of 

the  nature  of  the   mechanism  of   flat 

pelvis.     Most  authors  say  that  labor 

partakes  of  the  characteristics  of  both 

forms — combined   in    degrees   varying 

with  the  preponderance  of  either  de- 
formity, but  in  my  experience  the  head 

never   could   get  into   the  pelvis  far 

enough    to    meet    the    resistance   all 

around  and  thus  exaggerate  the  flexion. 

High  transverse  arrest  is  the  condition

usually  found,  and,  even  in  moderate  degrees  of  contraction,  cesarean  section  or,  on 
the  dead  or  dying  child,  craniotomy  is  often  necessary.  Not  seldom  the  accoucheur, 
thinking  he  has  to  deal  with  a  flat  pelvis,  meets  unexpected  difficulty,  and  investi- 
gation will  show  that  moderate  lateral  contraction  exists  in  addition.  Since  such 
contraction  of  the  sides  of  the  inlet  leaves  no  place  for  the  head,  compressed  in  the 
conjugata  vera,  to  expand  in,  these  difficulties  are  easily  explained,  and  generally  con- 
tracted fiat  pelves  present  the  most  formidable  complications  unless  early  recog- 
nized. 

MECHANISM  OF  LABOR  IN  FUNNEL  PELVES 

At  the  pelvic  outlet  the  resistance  begins,  and  the  head  comes  to  a  stop  at  this 
point.  Now  extreme  flexion  occurs,  and  the  labor  resembles  that  of  generally  con- 
tracted pelves.  If  the  funnel  shape  of  the  pelvis  is  due  to  kyphosis,  as  an  additional 
complication  the  spinal  column  may  overlie  the  inlet  (pelvis  obtecta)  and  prevent 
the  entrance  of  the  head  into  the  superior  strait.  If  spondylolisthesis  exists,  the 
same  obstruction  may  present,  and  then  labor  is  usually  impossible  without  cesarean 
section.  Klien  emphasizes  the  frequency  of  occipitoposterior  positions  and  forehead 
presentations.  Such  malpositions  are  probably  due  to  the  pendulous  uterus,  the 
fetal  back  fitting  best  to  the  posterior  uterine  convexity  and  its  belly  being  bent 
over  the  pubis. 

Pelves  contracted  transversely  at  the  outlet  are  not  so  rare  as  was  formerly 
thought.  Klien  has  shoA\Ti  their  immense  clinical  importance.  Since  the  con- 
traction lies  between  the  descending  rami  of  the  pubis  and  the  tuberosities  of  the 
ischia,  the  broad  occiput  cannot  use  this  space  during  its  passage  under  the  sjin- 
physis,  but  is  forced  backward  onto  the  perineum  and  against  the  sacrum  and  cocc\tc 
(Figs.  644,  645,  and  646).  As  a  result  the  perineum  and  levator  ani  are  often  torn, 
the  coccyx  broken,  and  if  the  sacrum  curves  too  far  forward,  labor  becomes  im- 
possible. The  author  is  convinced  that  a  large  number  of  forceps  cases  with  deep 
pelvic  floor  injuries  and  tearing  of  the  vagina  over  the  spines  of  the  ischia,  often  to 
the  walls  of  the  pelvis,  come  in  this  class  but  are  mirecogiiized. 

The  diagnosis  of  labor  in  funnel  pelves  ^\'ill  vary  with  the  engagement  or  non- 
engagement  of  the  head.  When  the  head  reaches  the  pelvic  floor  it  is  arrested, 
impacted  between  the  ischia,  but  usually  anterior  rotation  of  the  occiput  has  been 
completed.  Strong  bearing-down  efforts  produce  no  advance,  the  -perineum  is  not 
put  on  the  stretch,  bulging  does  not  occur,  and  the  parturient,  soon  perceiving  that 
her  bearing-down  efforts  produce  no  real  effect,  gives  up  trying  and  calls  for  relief. 
Internal  examination  will  disclose  the  head  in  exaggerated  flexion,  lying  closely 
packed  between  the  spines  of  the  ischia  and  covered  with  a  large  caput  succedaneum. 
Rotation  is  usually  complete,  but  sometimes  the  sagittal  suture  lies  in  the  transverse 
diameter — that  is,  ''deep  transverse  arrest"  has  occurred.  If  the  measurements  of 
the  pelvis  have  been  taken  in  the  routine  pregnancy  examination,  such  a  course  of 
labor  will  bring  no  surprise.  In  determining  whether  the  head  will  or  vnll  not  pass 
the  outlet  the  accoucheur  must  know  two  distances — first,  that  between  the  tuberos- 
ities of  the  ischia,  and,  second,  that  from  the  center  of  this  diameter  to  the  tip  of  the 
sacrum — the  "posterior  sagittal"  of  Klien. 

Klien  says  a  normal  outlet  has  a  transverse  diameter  of  11  cm.,  an  anterior 
sagittal  of  6  cm.,  a  posterior  sagittal  of  9.95  cm.,  but  my  owti  measurements  are  a 
little  smaller,  in  which  Williams  agrees. 

The  determination  of  the  bi-ischiatic  diameter  is  made  as  showm  in  Fig.  273 
(p.  243),  and  is  more  easily  measured  in  labor  than  at  any  other  time.  By  holding 
a  short  rod  in  this  diameter  and  applying  one  end  of  the  pelvimeter  to  its  center 
and  the  other  over  the  end  of  the  sacrum,  the  posterior  sagittal  is  obtained.  One 
centimeter  must  be  deducted  for  the  thiclmess  of  the  bone  and  soft  parts. 

It  is  apparent  that,  even  if  the  narrow  pubic  arch  forces  the  head  back  against 


f02

the  perineum  and  sacrum,  if  the  latter  does  not  curve  forward  too  much,  there  will 
still  be  plenty  of  room  for  the  passage  of  the  hyperfiexed  head — only  the  soft  parts 
will  be  much  endangered.     If  the  bi-ischiatic  diameter  is  less  than  8  cm.,  it  is  the

rule  to  experience  trouble  with  the  delivery  and  forceps  are  often  needed.  If, 
in  addition,  the  posterior  sagittal  (Fig.  646)  is  less  than  9  cm.,  labor  is  very  difficult 
or  even  impossible,  and  craniotomy  is  usually  finally  resorted  to.     Williams  and 


MECHANISM    OF   LABOR    IN    FLAT    PELVES 


ro3 


Klien  seem  agreed  that  a  pelvis  with  a  diameter  of  less  than  8.5  cm.  between  the 
tuberosities  and  a  posterior  sagittal  less  than  9  cm.  offers  insuperable  obstruction 
to  labor  and  demands  cesarean  section,  pul^iotomy,  or  craniotomy. 

Breech  lal)ors  are  especially  bad  in  funnel  and  transversely  contracted  pelves, 
because  the  head  has  no  time  to  mold,  and  forceps  on  the  after-coming  head  are  very 
often  required.  Even  then  many  babies  are  lost.  If  the  patient  is  a  very  old 
primipara,  and  if  it  seems  likely  that  the  present  'svill  be  the  only  pregnancy,  the 
high  infantile  mortality  and  the  severe  pelvic  injuries  which  are  inevitable  with 
forceps  dehvery  should  be  given  great  weight  when  deciding  for  or  against  cesarean 
section.  Forced  operative  delivery  in  such  cases  often  results  in  deep  lacerations 
of  the  vagina,  pelvic  floor,  and  rectum,  even  rupture  of  the  pubis,  and  shows  a  pain- 
fully high  infant  mortality. 


LABOR  IN  OBLIQUELY  CONTRACTED  PELVIS 

Ever^i:hing  depends  on  the  amount  of  contraction  of  the  conjugata  vera,  and, 
of  course,  on  the  forward  protrusion  of  the  promontory.  If  the  promontory  pro- 
jects low  toward  one  iliopubic  tubercle,  it  will  eliminate  that  half  of  the  pelvis, 
as  far  as  using  it  for  the  passage  of  the  head  is  concerned  (Figs.  647  and  648).     This

is  equivalent  to  a  generally  contracted  pelvis  of  highest  degree.  A  very  sharp  clinical 
distinction  must  be  made  l:)etween  pelves  which  are  simply  distorted,  but  with  little 
or  no  reduction  in  the  area  of  the  inlet  and  those  which  are  actually  contracted  or 
are  so  much  distorted  that  actual  contraction  results.  Generally  it  is  best  for  the  oc- 
ciput to  come  down  in  the  large  half  of  thepeh-is  (Figs.  648  and  649),  but  sometimes 
it  is  best  for  it  to  enter  pointing  toward  the  contracted  half.     Then  the  biparietal 


704  THE    PATHOLOGY    OF   LABOR 

diameter  will  lie  in  promonto-iliopubic  diameter,  and  the  forehead  come  down  over 
the  opposite  sacro-iliac  joint.  In  Naegele  pelves  the  labor  is  further  complicated  by 
the  reduction  in  size  of  the  passage  all  the  way  to  the  outlet.  In  rachitic  pelves  this 
does  not  obtain,  and,  once  the  head  passes  the  inlet,  labor  is  quickly  ended. 

In  several  of  the  author's  cases  the  occiput  did  not  rotate  to  the  front,  but  re-

mained  in  the  oblique,  and  the  head  escaped  over  one  or  the  other  ramus  pubis, 
the  latter  acting  as  the  fulcrum  against  which  the  nape  of  the  neck  stemmed,  while 
forehead  and  face  appeared  from  behind  the  opposite  ischial  tuberosity.  Breech 
labors  are  unwelcome  in  obliquely  contracted  pelves,  and  it  is  most  desirable  for 
the  occiput  to  come  down  on  the  side  not  contracted.  Such  a  mechanism  should  be 
brought  about,  if  possible,  during  operative  delivery.

CHAPTER  LVII 
PROGNOSIS  OF  LABOR  IN  CONTRACTED  PELVES 

The  Mother. — Naturally,  it  is  impossible  to  present  figures  of  the  mortality 
of  labor  in  contracted  pelvis,  and  the  morbidity  will  always  remain  indeterminable. 
Mild  degrees  of  pelvic  contraction  may  not  have  much  effect  on  the  labor  except 
by  the  production  of  malpresentations,  etc.,  which  demand  interference,  and  opera- 
tive measures  all  carry  a  certain  mortality  and  morbidity.  In  general,  the  prog- 
nosis of  a  given  labor  depends  upon,  first,  the  degree  of  pelvic  contraction;  second, 
the  size  and  hardness  of  the  child,  especially  of  its  head;  third,  the  presentation, 
position,  and  attitude;  fourth,  the  strength  of  the  pains.  If  a  complication,  as 
eclampsia  or  placenta  prsevia,  is  superadded,  the  prognosis  is,  of  course,  altered, 
and,  finally,  much  depends  on  the  cleanliness  and  skill  of  the  attendants. 

The  mother  is  exposed  to  the  following  dangers :  (1)  Obstructed  and  impossible 
labor,  which  eventuates  in — (a)  Rupture  of  the  uterus;  (6)  septicemia;  (c)  ex- 
haustion and  shock,  with  or  without  operation;  (2)  pressure  necrosis  of  the  walls 
of  the  genital  tract;  (3)  injuries  of  the  genital  tract,  for  example,  spontaneous 
rupture  of  the  uterus,  cervix,  vagina,  symphysis  pubis,  and  traumatic  rupture  of 
the  same;  (4)  infection  in  labor,  with  physometra  (tympania  uteri)  or  general 
septicemia;  (5)  exhaustion  and  shock. 

If  the  labor  is  completely  obstructed,  the  head  wedges  itself  into  the  narrow 
canal  and  becomes  firmly  fixed  (paragomphosis),  the  vagina  and  vulva  become 
enormously  swollen,  suggillated,  and  almost  black,  sometimes  sloughing  out 
entirely.  In  the  less  severe  cases  the  constant  pressure  produces  areas  of  necrosis 
which  later  make  deforming  scars  or  slough  out,  leaving  fistulas, — rectovaginal, 
vesicovaginal,  uterovaginal,  etc., — depending  on  the  part  of  the  pelvic  viscera  wliich 
underwent  the  severest  compression  between  the  head  and  the  pelvis.  Flat  pelves 
cause  more  fistulas  than  generally  contracted,  because  in  the  latter  the  pressure 
is  more  evenly  distributed.  Pressure  necrosis  of  the  posterior  cervical  wall  may 
cause  adhesion  of  the  peritoneum  over  the  uterus  and  that  covering  the  promontory, 
retrofixation  of  the  uterus  resulting.  The  fistulas  are  often  not  apparent  for  a  few 
days,  that  is,  it  requires  this  time  for  the  slough  to  separate  and  establish  com- 
munication between  the  two  cavities. 

Injuries  usually  are  the  result  of  operative  delivery,  but  sometimes  the  uterus 
itself,  acting  with  terrific  force,  may  force  the  child  through  its  own  walls,  or  through 
the  unprepared  cervix  or  perineum,  or  may  even  burst  the  pubic  symphysis.  Rarely 
the  sacro-ihac  joints  are  separated.  Traumatic  injury  of  the  soft  parts  is  due  to  too 
early  and  too  forcible  attempts  at  delivery,  and  even  a  skilful  accoucheur  may  cause 
it  Avhen  the  tissues  are  softened  and  brittle  from  disease  or  long  labor.  The  scars 
from  these  injuries  may  distort  the  pelvic  viscera,  causing  malpositions  of  the  uterus, 
chronic  pelvic  congestion,  dislocation  of  the  bladder,  pulling  open  the  sphincter 
vesicae  causing  incontinence,  etc. 

Infection  in  labor  may  come  from  without, — the  usual  way, — the  phj'sician 
carrying  the  bacteria  either  on  undisinfected  hands  or  transferring  them  from  the 
vulva  and  vagina  into  sterile  regions,  and  it  may  occur  spontaneously,  the  result 
of  the  reduction  of  local  and  general  immunity.  Local  immunity  is  destroyed  in 
prolonged  labor  by  the  loss  of  the  epithelium,  its  weakening  by  imbibition,  by  the 
alteration  of  the  secretions  of  the  parturient  tract,  the  clear  mucus  being  replaced 
45  705 


706  THE   PATHOLOGY   OF   LABOR 

by  serum  and  blood,  and,  third,  the  local  traumatisms.  The  liquor  amnii  is  very- 
prone  to  decomposition,  and  once  the  interior  of  the  uterus  is  infected,  the  general- 
ization is  rapid.  Tjnnpania  uteri  is  sometimes  due  to  the  Bacillus  aerogenes  cap- 
sulatus,  but  more  often  to  the  Bacterium  coli  commune.  General  immunity  is 
weakened  by  the  exhaustion  and  shock  of  the  prolonged  labor,  anesthetics,  and 
operations.  Tetanus  uteri  is  of  grave  omen.  While  it  does  not  favor  rupture  of 
the  uterus,  labor  comes  to  an  absolute  stop,  and  unless  aid  is  rendered,  mother  and 
child  are  lost  from  exhaustion  and  sepsis. 

Exhaustion  and  shock  must  not  be  forgotten  as  complications  of  prolonged 
labor,  and  too  much  given  the  patient  to  overcome.  In  Avomen  of  gracile  type,  the 
highly  polished  output  of  our  finishing  schools,  with  one  or  several  generations  of 
overcivilized  ancestors,  the  shock  of  hard  labor  is  badly  borne,  and  the  nervous 
system  may  suffer  permanent  damage.  While  contracted  pelves  are  uncommon  in 
this  class  (perhaps  a  tendency  to  general  smallness  may  be  noted) ,  the  children  are 
usually  well  grown,  and  since  the  uterine  action  is  nearl}^  alwaj's  deficient,  operative 
interference  is  frequently  required.  It  is  important  to  watch  the  effect  of  labor  on 
the  nervous  system  and  interfere  before  serious  inroads  have  been  made  on  it. 

Breech  and  shoulder  presentations,  in  some  respects,  are  better  for  the  mother 
than  the  head,  because  they  do  not  cause  pressure  necrosis,  and  early  attention  is 
called  to  the  anomalous  pelvis.  The  passage  of  the  child  in  delivery-  is  rapid,  and 
experience  shows  that  intense  compression  of  short  duration  is  less  dangerous  to  the 
tissues  than  a  mild  pressure  kept  up  for  a  long  time. 

The  Child. — In  the  highest  degrees  of  pelvic  contraction  the  child  has  the  oest 
chances  for  its  life,  because  the  al)solute  disproportion  is  usually  early  recognized 
and  cesarean  section  performed.  In  the  very  slight  pelvic  contractions  the  infant 
mortality  is  not  much  higher  than  usual,  but  anomalies  of  the  mechanism  of  labor 
must  be  remembered.  Many  children  still  are  lost  in  the  cases  where  the  pelvis 
is  contracted  enough  to  show  in  the  course  of  lal^or,  and  this  is  because  the  ac- 
coucheur has  not  carefuUj'  studied  his  patient.  Too  many  women  are  blindly  al- 
lowed to  go  into  labor,  and  only  after  the  good  time  for  cesarean  section  or  pubiot- 
omy  has  gone  by  is  the  spacial  disproportion  discovered.  Often  it  is  found  only 
after  the  accoucheur  has  failed  to  deliver  with  forceps. 

Asphyxia  causes  the  largest  number  of  fetal  deaths,  and  it  is  brought  about  by 
— (1)  Interference  with  the  placental  circulation,  the  result  of  the  frequent  and 
powerful  uterine  contractions — the  blood  is  forced  out  of  the  uterus  by  the  pains; 
(2)  compression  of  the  brain  as  the  head  is  jammed  through  the  inlet — the  pressure 
irritates  the  pneumogastric,  slows  the  pulse,  and  compromises  still  further  the  oxy- 
genation of  the  fetal  blood;  (3)  as  the  effect  of  the  early  rupture  of  the  membranes 
and  the  escape  of  the  liquor  amnii  the  uterus  retracts,  theplacental  area  is  diminished, 
and  abruption  of  the  organ  is  favored;  (4)  prolapse  of  the  cord  is  common,  espe- 
cially in  flat  pelves,  and  this  is  always  a  very  serious  affair  for  the  child.  As  long 
as  the  bag  of  waters  is  intact  these  dangers  hardly  exist,  but  it  would  be  wrong  to 
say  they  never  threaten  the  child,  because  I  have  seen  deaths  of  the  fetus  occur  by 
the  above  mechanisms  with  an  intact  amniotic  sac. 

Injuries  of  the  brain,  of  the  cranium,  and  of  the  body  of  the  child  are  very  com- 
mon. iMany  children  die  from  cerebral  compression  without  external  injury,  and 
not  a  few  die  from  concussion  of  the  brain  from  forceps  or  breech  delivery.  More 
often  death  is  due  to  intracranial  hemorrhage  from  skull  fracture.  This  may  be  in 
the  form  of  fissures  radiating  from  the  center  of  ossification  of  the  flat  bones  toward 
the  sutures  of  the  skull.  Many  times  cephalhematoma  is  due  to  such  fissures,  the 
clot  in  these  instances  being  outside  the  skull,  under  the  periosteum.  Depressed 
skull  fractures  occur  with  forceps,  but  particularly  with  ])reech  deliveries,  and  they 
look  as  if  the  })one  had  been  pressed  in  with  a  spoon  (Fig.  G50).  They  are  sometimes 
attended  by  intracranial  hemorrhage,  and  are  then  usually  fatal.     They  are  most

often  located  between  the  parietal  bosses  and  the  coronary  sutures,  but  one  of  my 
cases  showed  the  depression  right  behind  and  above  the  left  ear. 

If  not  primarily  fatal,  the  child  may  recover  and  show  no  signs  of  permanent 
damage  to  the  brain,  the  deformity  becoming  less  with  time,  but  never  disappearing. 
Another  form  of  skull  depression,  not  always  a  fracture,  because  the  bone  is  soft 
and  flexible,  is  the  groove  (Fig.  Gol).  This  deformity  is  due  to  the  molding  of  the 
head  by  the  sharp  promontory,  and  disappears  almost  entirely  in  a  few  months. 
It  is  harmless  of  itself,  but  may  be  serious  if  large,  deep,  or  complicated  by  fracture 
.or  intracranial  hemorrhage.  These  flat  depressions  usually  parallel  the  coronary 
suture.  They  require  no  treatment.  Separation  of  the  flat  bones  at  the  basilar 
sutures  is  one  of  the  worst  of  the  birth  injuries,  because  the  large  cerebral  blood- 
sinuses  lie  in  the  neighborhood,  and  if  torn,  allow  fatal  intracranial  hemorrhage.

The  parietal  bone  may  tear  away  from  the  squamous  portion  of  the  temporal 
bone  at  the  anterior  lateral  fontanel — the  sutura  squamosa;  the  occipital  plate 
may  separate  from  the  condyles.  In  the  latter  instance  the  plate  then  may  be 
dislocated  directly  onto  the  medulla,  causing  immediate  death. 

The  morbidit}'  of  children  delivered  through  contracted  pelves  is  also  very 
large. 

Pressure  necrosis  of  the  scalp  has  been  already  mentioned.  This  may  be  in 
all  degrees  from  a  simple  desquamation  with  redness  to  actual  sloughing  of  the 
tissues,  with  laying  bare  of  the  bone  and  exfoliation  of  sequestra— in  a  few  instances 
followed  by  meningitis.  These  pressure  marks  are  made  by  the  promontory,  but 
sometimes  by  an  exostosis  on  the  posterior  surface  of  the  pubis,  and  are  the  external 
evidence  of  long  labor.     Fistulas  in  the  mother  usually  result  at  the  same  time. 


708  THE    PATHOLOGY    OF    LABOR 

Cephalhematoma  is  a  complication  of  fractures  of  the  skull.  The  clot  lies  under 
the  external  periosteum,  is  limited  always  by  the  sutures,  msiy  be  single  or  mul- 
tiple, external  and  internal  combined,  and  may  cover  a  depressed  fracture.  These 
hematomata  alone  are  not  fatal,  but  require  many  months  for  complete  resorption, 
and  leave  a  ridge  of  bone  at  the  edges  for  many  weeks  more. 

Caput  succedaneum  occurs  in  its  greatest  proportions  in  contracted  pelves. 
It  may  be  visible  at  the  vulva  while  the  head  has  not  yet  passed  the  inlet.  Since 
the  caput  succedaneum  is  due  to  the  fact  that  the  pressure  inside  the  uterus  is 
greater  than  that  in  the  vagina,  it  indicates  strong  uterine  action.  It  does  not  show 
that  the  head  fits  the  inlet  tightly,  and  it  does  not  do  much  to  aid  in  the  dilatation 
of  the  cer\'ix,  as  some  writers  state. 

In  generally  contracted  pelves  the  caput,  by  lengthening  the  head  wedge, 
may  assist  the  labor,  but  little  is  thus  accomplished.  Of  great  clinical  importance 
is  the  proper  estimation  of  the  caput,  because  if  the  scalp  is  visible  at  the  vulva, 
the  accoucheur  may  hastily  conclude  that  the  head  is  engaged  and  be  misled  into 
unfortunate  operating,  while  in  reality  the  head  may  be  above  the  inlet.  The  caput 
also  covers  up  the  landmarks  of  the  head  and  renders  the  diagnosis  of  position  very 
difficult. 

Fractures  of  the  clavicle,  the  humerus,  and  the  femur  and  disruption  of  the 
vertebral  column  are  almost  invariably  due  to  brute  force,  exhibited  during  oper- 
ative deliver}'.  The  same  may  be  said  of  tearing  of  the  nerves  of  the  cervical  plexus 
— Erb's  paralysis,  etc.  Fracture  of  the  long  bones  and  of  the  skull  may,  however, 
occur  during  spontaneous  labor. 

The  author  is  convinced  that  many  children  carry  the  effects  of  minor  injuries 
received  at  birth  all  their  lives.  It  stands  to  reason  that  the  innumerable  and 
thickly  sown  minute  hemorrhages  found  in  the  brain  after  forceps  and  other  hard 
deliveries  must  leave  at  least  a  fibrosis  behind.  These  thickenings  may  explain 
cases  of  epilepsy,  idiocy,  paralyses,  pareses,  chronic  headache,  tic  douloureux,  retinal 
lesions,  strabismus,  and  some  other  focal  nerve  diseases  in  later  life.  Even  abnor- 
mal moral  and  mental  conditions  might  be  explained  as  clue  to  injuries  sustained  at 
birth,  though  at  present  there  is  little  evidence  to  support  the  theory.  Such  a 
belief  would  increase  the  burden  of  responsibility,  already  too  heavily  laid,  on  the 
shoulders  of  the  accoucheur. 

The  outlook  for  the  child  depends,  of  course,  on  the  degree  of  pelvic  contrac- 
tion, the  severity  of  the  operative  delivery,  the  skill  of  the  accoucheur,  and  the 
nature  of  the  operation. 


CHAPTER  LVIII 
TREATMENT  OF  CONTRACTED  PELVIS 

No  subject  in  medicine  presents  greater  difficulties  in  all  its  aspects  than  this 
one,  and  none  demands  so  much  art  or  practical  skill.  Science  aids  little  here. 
Knowledge  of  the  passages,  of  the  powers,  of  the  passengers,  of  the  mechanism  of 
labor,  all  help  a  great  deal,  but  more  depends  on  experience  and  judgment.  Even 
large  experience  is  fallacious  and  judgment  is  difficult — the  words  of  Hippocrates, 
the  truth  of  which  is  often  proved  when  the  accoucheur  finds  that  a  fetus  he  said 
could  not  pass  through  a  certain  pelvis  is  delivered  before  he  can  reach  the  bedside, 
and  another  which  he  confidentl}'  predicted  would  he  born  easily  requires  a  grave 
operation.  Many  factors  besides  the  pelvic  contraction  enter  into  the  course  of  the 
labor,  and  success  in  treatment  depends  on  the  proper  valuation  of  each  and  the 
proper  placement  of  their  relations  to  each  other.  Some  of  these  factors  can  be 
accurately  evaluated  before  or  during  labor,  others  partlj^  and  a  few  not  at  all. 
These  factors  are  the  attitude,  presentation,  and  position  of  the  child,  the  size  and 
hardness  of  its  head,  the  shape  of  its  body,  whether  there  are  one  or  two  fetuses, 
the  shape  of  the  pelvis,  that  is,  the  distribution  of  the  available  space,  the  height 
of  the  promontory,  the  inclination  of  the  inlet,  the  movability  of  the  pelvic  syn- 
chondroses, the  state  of  the  soft  parts,  the  character  of  the  uterine  contractions 
(strong  pains  being  able  to  accomplish  wonderful  results),  the  presence  or  absence 
of  infection  in  the  parturient  canal,  the  nervous  temperament  of  the  parturient,  and 
her  general  health.  Outside  factors  must  also  often  be  considered:  (1)  The 
environment,  whether  the  parturient  is  in  a  squalid  tenement,  in  the  country,  in  a 
home  where  every  appliance  is  obtainable,  or  in  a  well-equipped  maternity;  (2) 
whether  in  the  hands  of  the  general  practitioner  or  a  trained  specialist;  (3)  if 
the  patient  is  a  Catholic,  all  medically  indicated  procedures  not  being  permitted; 
(4)  the  age  of  the  parturient  and  the  probability  of  her  having  more  children. 
Even  with  this  enumeration,  the  possible  factors  which  might  influence  a  labor  or 
our  decision  regarding  the  course  to  pursue  have  not  all  l^een  mentioned.  It  must 
alwaj'sbebornein  mind  that  nature  is  able  to  overcome  the  difficulties  of  contracted 
pelves  in  the  majority  of  cases.  Luclwig  and  Savor  found  that  75  per  cent,  of  such 
cases  terminate  spontaneously  when  the  conjugata  vera  is  not  less  than  9.5  cm.; 
that  58  per  cent,  with  a  conjugata  vera  of  9  cm.,  50  per  cent,  with  one  of  8.5  cm., 
and  25  per  cent,  with  one  of  8  cm.,  require  no  aid  from  art.  A  course  of  watchful 
expectancy  was  all  that  was  needed  in  these  labors. 

Diagnosis  of  Disproportion. — In  all  cases  the  first  thing  to  determine  is  the 
existence  and  degree  of  disproportion  between  the  child  and  the  pelvis;  in  other 
words,  the  question  must  be  answered,  will  the  child  go  through  the  pelvis?  The 
routine  measurement  of  the  pelvis  of  everj^  pregnant  woman  coming  under  his  care 
will  have  chrected  the  accoucheur's  attention  to  the  existence  of  obstruction  in  the 
birth-canal.  When  labor  begins,  another  examination  should  be  made  because 
it  is  much  easier  to  obtain  the  internal  measurements  at  this  time.  (See  p.  240.) 
The  history  of  previous  labors  is  of  great  value,  but  it  must  be  carefully  sifted.  A 
woman  may  have  had  severe  dystocia,  even  craniotomy  or  cesarean  section,  and 
yet  have  a  normal  pelvis  which  would  give  no  trouble  in  the  present  labor.  It  is 
possible,  with  moderate  experience  and  thorough  application  of  our  present  meth- 
ods, to  obtain  a  quite  accurate  knowledge  of  the  actual  size  of  the  pelvic  lumen.

THE    PATHOLOGY   OF   LABOR 


Not  SO  much  may  be  said  of  the  child.  It  is  harder  to  form  an  opinion  of  its  size, 
and  still  harder  to  estimate  the  ossification  and  configurability  of  its  head.  The 
intra-uterine  length  of  the  child  is  easily  measured  (p.  267).  With  the  cephalometer 
the  transverse  or  the  oblique  diameters  of  the  head  can  be  obtained,  and  by  de- 
ducting 23^  or  1^  cm.,  the  biparietal  diameter  is  approximately  estimated — at 
least,  one  gains  a  fairly  accurate  idea  of  the  size  of  the  head.  By  grasping  the  child 
from  the  outside  and  placing  the  fingers  against  the  head  per  vaginam,  one  may 
balance  its  body  between  the  two  hands  and  guess  its  weight  and  size.  If  the 
accoucheur  will  make  this  little  manoeuver  a  part  of  his  routine  in  every  labor, 
checking  up  his  guesses  by  weighing  the  children  after  delivery,  he  will  be  surprised 
to  find,  after  a  few  years,  how  accurately  he  can  estimate  their  weight.     One  de-

This  head  would  probably  not  enter  the  pelvis. 


termines  the  hardness  of  the  fetal  head  by  the  general  impression  of  firmness  of  the 
bones  conveyed  to  the  fingers,  the  sharpness  of  the  contour  of  the  parietal  bosses, 
the  size  of  the  fontanels  (if  almost  obliterated,  it  shows  hyperossification),  the 
extent  to  which  the  bones  overlap  during  the  pains,  and  the  breadth  of  the  dome  of 
the  cranium.  If  the  bones  are  soft,  the  dome  is  acute,  while  a  hard  calvarium  is 
more  flat.  Previous  children  may  have  been  large  or  small,  with  hard  or  soft 
heads,  and  the  length  of  the  present  pregnancy  must  also  be  taken  into  considera- 
tion.    Children  that  are  carried  overterm  usually  have  large  hard  heads. 

After  getting  as  good  a  general  idea  as  possible  of  the  size  and  consistence 
of  the  child,  the  accoucheur  tries  to  determine,  by  more  direct  means,  if  the  head 
is  likely  to  go  through  the  pelvis.  For  this  purpose  it  is  better  if  the  woman  has 
been  in  actual  labor  until  the  cervix  is  effaced  and  pulled  up  out  of  the  pelvis,  thus

allowing  the  fetal  head  to  apply  itself  more  eloselj-  to  the  inlet.  However,  such 
conditions  are  not  always  met,  and  one  has  to  form  his  judgment  by  allowing  duly 
for  disturbing  factors.  Fig.  652  shows  the  first  manoeuver.  The  head  is  forced 
down  onto  the  inlet,  the  fingers  inside  steadying  it,  and  it  is  then  easy  to  find  if  the 
anterior  parietal  boss  projects  in  front  of  the  posterior  surface  of  the  pubis  and  how 
much.  If  the  child  presents  with  the  occiput  posterior,  the  forehead  will  be  quite 
prominent  in  front,  and  this  point  must  not  be  forgotten.  A  full  rectum  will  also 
push  the  head  forward.  Miiller's  procedure  consists  in  having  an  assistant  force 
the  head  do'UTi  into  the  inlet 
while  the  inside  fingers  deter- 
mine how  far  it  enters  the  pel- 
vis. It  has  value  only  after 
the  cervix  is  out  of  the  waj^,  be- 
cause the  soft  parts  will  prevent 
the  head  from  engaging  under 
the  amount  of  dowmward  pres- 
sure it  is  possible  safely  to  exert 
by  the  two  hands.  The  most 
valuable  of  all  is  the  determina- 
tion of  the  degree  of  engage- 
ment. Reference  has  already 
been  made  to  the  criteria  of  en- 
gagement of  the  fetal  head.  If 
the  vault  of  the  pehds  is  empty, 
the  head  being  high  and  float- 
ing, in  the  absence  of  other 
causes  for  non-engagement  the 
pehds  is  probal^ly  much  con- 
tracted; if  the  head  enters  the 
region  of  the  inlet  with  a  large 
segment  projecting  into  the 
excavation  and  is  more  or  less 
fixed,  the  accoucheur  maj'  feel 
fairly  sure  that  the  pains  will  suc- 
ceed in  molding  it  sufi5ciently 
for  spontaneous  dehvery. 

Passing  the  fingers  around 
the  head  and  alternately  touch- 
ing the  walls  of  the  pelvis  it  is 
not  hard  to  form  a  quite  accur- 
ate conception  of  the  degree  of 
disproportion.  Combined  pal- 
pation of  the  head,  like  that 
used  in  estimating  the  size  of  the 
uterus,  gives  useful  information. 

If  the  lowest  portion  of  the  head  has  reached  the  interspinous  line  (Fig.  653),  engage- 
ment is  usually  certain.  In  flat  rachitic  pelves  the  side  walls  are  so  low  that  this 
sign  must  be  ciuahfied.  Here  the  lowest  portion  of  the  head  nmst  have  passed  this 
line  by  a  little.  The  other  signs — the  covering  of  the  sacrum  and  of  the  pubis — 
are  also  valuable,  particularly  the  former. 

Now  a  minute  diagnosis  of  presentation,  position,  and  attitude  must  be  made. 
If  the  child  presents  in  a  frank  O.L.A.,  the  probabilities  of  a  disturbing  degree  of 
pelvic  contraction  are  not  so  strong.  If  the  anterior  or  posterior  parietal  bone  pre- 
sents and  the  attitude  does  not  correct  itself  under  the  influence  of  the  pains,  usually

The  fingers  touch  the  left  ischial  spine,  then  swing  around  peh'is  to

712  THE    PATHOLOGY    OF    LABOR 

a  badly  contracted  pelvis  exists.  The  presence  of  anterior  or  posterior  parietal 
bone  presentation  generally  must  be  taken  as  an  indication  of  grave  dystocia,  though 
nature  often  terminates  such  cases  happily.  However,  in  deciding  Ijcforehand 
whether  a  given  head  will  pass  through  a  given  pelvis  these  abnormal  i)resentations 
are  very  significant,  because  if  they  are  very  marked,  the  likelihood  of  a  successful 
spontaneous  deliver}^  is  remote. 

A  careful  study  of  the  uterine  action  is  now  in  order.  Good  regular  pains  may 
overcome  great  resistances.  Weak,  infrequent,  irregular,  or  cramp-like  pains  may 
be  unable  to  terminate  a  labor  otherwise  normal.  The  nervous  constitution  of  the 
woman  will  also  require  some  attention.  A  nervous,  impatient,  unruly  disposi- 
tion, or  even  acute-nervous  prostration,  may  be  the  cause  for  interference  when  the 
mechanical  disproportion  is  not  great. 

Finally,  we  have  the  test  of  labor,  but  the  attendant's  decision  regarding  his 
conduct  of  the  case  must  be  made  before  he  trusts  the  case  to  nature. 

For  purposes  of  discussion  it  is  customary  to  divide  contracted  pelves  into  four 
classes.  It  must  be  emphasized,  at  the  very  start,  that  such  a  division  is  purely 
arbitrary-,  because  the  size  of  the  child  is  not  considered,  nor  are  any  of  the  above- 
mentioned  factors  allowed  for,  but  some  common  basis  for  discussion  must  be  had. 

I.  Pelves  with  a  conjugata  vera  less  than  5}^^  cm.  in  the  flat,  and  6  cm. 

in  the  generally  contracted,  variety.     These  are  absolutely  contracted. 

II.  Pelves  with  a  conjugata  vera  of  53^2  to  l]/2  cm.  in  flat,  and  6  to  8  cm. 

in  the  generally  contracted,  types.     These  are  relatively  contracted. 

III.  Pelves  with  a  conjugata  vera  of  73^2  to  9  cm.  in  flat,  and  8  to  93^  cm. 
in  the  generally  contracted.     These  are  moderatelj^  contracted. 

IV.  Pelves  with  a  conjugata  vera  over  9  and  93^  cm.  respectively,  and 
are  border-line  cases. 

I.  In  the  absolutely  contracted  pelvis  no  difficulty  is  met  in  deciding  on  treat- 
ment. A  full-sized  child  camiot  be  delivered  through  it,  and  for  this  reason  cesarean 
section  is  indicated  whether  or  not  the  child  is  living.  This  is  the  absolute  indication 
for  the  operation.  If  the  woman  is  seen  early  in  pregnancy,  therapeutic  abortion 
comes  up,  but  the  author  does  not  recommend  it,  prefering  cesarean  section  at 
term,  under  the  ideal  conditions  always  obtainable  when  the  pelvic  contraction 
is  so  timely  recognized.  If  the  accoucheur  is  called  late  in  labor,  when  infection  is 
probably  present,  Porro  cesarean  section  is  indicated. 

II.  In  the  relatively  contracted  pelvis  (conjugata  vera,  oYz  and  6  to  73^  and  8 
cm.)  decision  also  is  not  very  difficult.  If  the  child  is  dead,  craniotomy  is  indicated. 
A  full-sized  child  cannot  be  gotten  through  the  pelvis  alive,  and  the  question  to 
decide  is  shall  the  mother  be  subjected  to  the  risks  of  cesarean  section  in  order  to 
save  the  infant?  This  is  the  relative  indication  for  cesarean  section,  and  it  may  he 
allowed  only  under  certain  conditions.  If  the  woman  has  been  in  active  labor  a 
long  time;  if  the  membranes  have  been  ruptured  for  many  hours;  if  frequent  in- 
ternal examinations  have  been  made,  and  by  hands  whose  asepsis  cannot  be  assured ; 
if  operative  delivery  has  been  attempted;  if  infection  has  begun  or  is  suspected — 
certainly  if  the  woman  has  fever  or  fetid  tlischarge,  cesarean  section  from  the  relative 
indication  is  prohibited.  If  these  conditions  do  not  exist,  but  the  case  has  come  early 
into  the  hands  of  a  man  capable  of  his  task,  uninfected,  and  in  suitable  surround- 
ings, the  cesarean  section  is  the  operation  of  election.  In  the  first  instance  crani- 
otomy is  not  alone  justifiable,  but  demanded,  and  in  the  second  instance  the  ac- 
coucheur must  recommend  the  abdominal  delivery.  The  facts  are  to  be  laid  l)efore 
the  patient,  the  husband,  and  the  family,  and  they  must  decide.  Naturally,  the 
accoucheur  should  guide  them  in  the  decision,  and  if  they  do  not  agree  with  him, 
he  should  not  be  constrained  to  sacrifice  the  child  when  the  conditions  are  ideal  for 
cesarean  section.     Nor  should  he,  when  convinced  that  the  disproportion  is  too 


TREATMENT  OF  CONTRACTED  PELVIS  713 

great,  allow  the  woman  to  labor  until  the  right  time  for  the  abdominal  delivery  has 
gone  by.  He  is  at  liberty  to  retire  from  the  case  under  either  circumstance,  but 
must  first  provide,  or  see  that  the  family  provides,  other  medical  assistance.  Extra- 
peritoneal cesarean  section  has  not  yet  proved  its  superiority  over  the  classic 
method.     Its  consideration  will  be  reserved  for  a  separate  chapter. 

If  craniotomy  has  to  be  performed  because  of  pelvic  contraction,  the  woman, 
the  husband,  and  the  family  must  be  instructed  that  in  the  event  of  a  subsequent 
pregnancy  medical  aid  is  to  be  provided  early,  and  arrangements  made  for  the 
cesarean  section  under  ideal  conditions.  The  accoucheur  should  not  be  asked  to 
perform  craniotomy  a  second  time  on  the  same  woman.  Such  an  operation  to- 
day is  unjustifiable,  owing  to  the  perfection  of  obstetric  art. 

An  immense  mass  of  literature  has  been  accumulated  on  the  question  of  the  justifiability  of 
craniotomy  on  the  living  cliild.  In  a  paper  pubhshed  in  1901  (American  Journal  of  Obstetrics, 
vol.  xliv,  Xo.  4)  the  author  considered  the  subject  in  all  its  aspects,  and  has  changed  his  opinions 
but  httle  since. 

Kossmann,  ]\Iann,  Leopold,  Olshausen,  Schauta,  Chrobak,  and  Knapp  have  written 
cxhaustivel}^  on  it  and  reached  the  same  general  conclusions.  The  stand  taken  bj^  the  Catholic 
Church  is  well  known.  Under  no  circumstances  may  human  life  be  deliberately  taken  even  when 
it  is  done  to  save  another  life.  In  Catholic  families,  therefore,  the  accoucheur  is  in  duty  bound 
to  consider  this  aspect  of  the  case,  and  the  author  makes  it  an  invariable  rule  to  remind  the  patient 
and  family  of  this  view  of  the  Church,  and  to  ask  that  the  family  priest  be  summoned  to  aid  in 
their  deliberations. 

With  few  exceptions,  all  experienced  writers  are  agreed  that  the  sacrifice  of  the  living  child 
is  still  justifiable.  The  cases  in  which  this  is  necessary  are  very  scarce  and  becoming  scarcer 
each  year,  there  having  been  so  much  improvement  in  obstetric  teaching  and  practice  that 
severe  dystocia  is  more  often  recognized  early — in  time  for  life-saving  operations.  Neglected 
and  unrecognized  cases  do  still  occur,  mistaken  and  unsuccessful  operations  are  still  attempted, 
a.septic  care  of  parturients  is  still  not  universal,  and  infection  is  still  common,  so  that  when  the 
accoucheur  finally  has  to  complete  the  delivery,  he  is  usually  glad  to  be  able  to  save  one  life. 
Again,  a  woman  may  absolutely  refuse  to  endanger  her  own  life  for  her  child,  and  this  she  has  a 
perfect  right  to  do.  On  the  other  hand,  the  necessity  of  sacrificing  a  perfectly  healthy  child 
almost  never  arises.  When  the  patient  reaches  this  point  the  child  has  nearly  always  been  injured 
by  long  labor,  bj^  attempts  at  delivery,  by  being  infected  or  having  inspired  infected  hquor  amnii, 
and  it  very  often  dies  within  a  few  days,  even  if  deUvered  alive.  Furthermore,  30  per  cent,  of 
all  children  die  before  they  are  five  years  old.  In  comparing  the  life  values  of  mother  and  cliild, 
this  point  must  be  considered. 

Without  doubt,  in  former  years  too  many  children  were  sacrificed  and  infantile  life  was 
held  too  cheaply.  Nowadays  we  are  saving  a  great  many  by  means  of  cesarean  section  and  pubi- 
otomy,  but  there  is  a  tendency,  as  Chrobak  observes,  to  go  to  the  other  extreme,  and  expose  the 
mothers  to  greater  dangers  than  the  end  justifies.  As  Chrobak  says,  "it  almost  seems  we  must 
protect  the  mothers  against  the  children  and  that  we  forget  that  salus  matris  suprema  lex."  Since 
the  vast  majority  of  births  occurs,  not  in  the  large  cities,  where  maternities  and  specialists  are 
obtainable,  but  in  towns,  villages,  and  in  the  country,  it  'will  follow  that  many  children  will  have 
to  be  sacrificed  to  save  the  mothers,  and  the  accoucheur  will  deserve  congratulations  if,  under 
trying  circumstances  and  amid  unfavorable  conditions,  he  saves  the  mother.  Every  accoucheur, 
however,  breathes  one  prayer — speed  the  day  when  craniotomy  of  the  living  child  can  be  abolished! 

in.  In  the  moderately  contracted  pelves,  those  with  a  conjugata  vera  of  73^  to 
9  cm.,  and  8  to  932  cm-  (in  the  flat  and  generally  contracted  types  respect ivelj^), 
the  most  delicate  questions  and  the  greatest  difficulties  arise. 

Treatment  During  Pregnancy. — Induction  of  Premature  Labor. — Since  a  small 
infant  with  a  soft  small  head  can  usually  pass  through  a  moderately  contracted 
l^elvis  and  survive,  we  may  make  use  of  this  knowledge  and  induce  labor  at  a  period 
of  pregnancy  when  the  child  has  not  yet  attained  a  size  sufficient  to  block  the  pelvis. 

Louise  Bourgeois  (born  1563,  died  1636),  midwife  to  Marie  de  Medicis,  first  recommended 
and  practised  the  induction  of  premature  labor  to  save  the  life  of  the  mother,  and  gave  as  indication 
intractable  hemorrhage.  Roussel  de  Vauzelme,  in  1778,  recommended  the  operation  in  contracted 
peh-is,  saying  that  Petit  had  practised  it  many  years.  In  the  middle  of  the  nineteenth  century 
the  operation  had  a  good  vogue,  and  deserved  it,  because  the  mortahty  of  cesarean  section,  sym- 
physiotomy, and  craniotomy  was  so  high.  As  the  technic  and  results  of  these  operations  improved 
the  preference  went  to  them,  because  of  the  high  infant  mortality  and  dangers  and  troublesome 
complications  of  induced  labor,  but  even  today  the  majority  of  authorities  agree  that  the  induction 
of  labor  after  viability  of  the  child  is  a  valuable  operation. 

If  the  contraction  of  the  pelvis  is  known  early  in  pregnancy,  the  course  of 


714  THE    PATHOLOGY   OF    LABOR 

treatment  to  be  pursued  must  be  at  once  decided  upon.  Alany  women  consider  a 
previous  diifieult  labor  sufficient  indication  for  the  induction  of  abortion,  and  come 
to  the  physician  'U'ith  this  request.  In  the  first  place,  a  previous  difficult  labor 
may  have  been  due  to  entirely  different  causes  or  even  incompetent  medical  care, 
and  in  the  class  of  pelves  under  consideration  this  indication  will  never  arise,  be- 
cause, if  necessary,  labor  can  be  induced  after  fetal  viability,  with  no  more  danger 
than  abortion  and  with  over  60  per  cent,  chances  of  saving  the  infant.  The  facts 
are  to  be  laid  before  the  famih',  but  the  accoucheur's  decision  not  to  do  an  abortion 
should  be  final.  Primarily,  it  must  be  stated  that  a  large  number — perhaps  75 
per  cent. — of  labors  in  such  pelves  terminate  spontaneously  at  or  near  term;  second, 
that  cesarean  section  performed,  as  it  can  be,  when  the  need  for  it  is  knowTi  so  far 
beforehand,  has  a  very  low  mortality — less  than  2  per  cent.;  third,  that  should  the 
event  prove  that  labor  will  not  terminate  spontaneously,  in  pubiotomy  we  have  an 
operation  that  wall  still  save  the  child  and  not  seriously  endanger  the  mother; 
fourth,  that  should  all  our  plans  fail,  craniotomy  could  still  be  performed  as  a  last 
resort  after  the  test  of  labor  has  been  faithfully  tried. 

On  the  other  hand,  the  operation  of  induced  lal)or  is  not  absolutely  safe. 
Statistics  give  the  maternal  mortality  as  1  to  2  per  cent.,  but  nowadays,  in  the  hands 
of  a  capable  accoucheur,  there  should  be  no  mortality.  From  20  to  30  per  cent. 
of  the  children  are  lost  in  labor,  and  another  portion  dies  within  a  few  weeks,  in 
spite  of  the  incubator,  good  nursing,  etc.  Then,  too,  the  uterus  is  sometimes  very 
sluggish  and  torpid,  requiring  much  stimulation,  instrumentation,  frequent  ex- 
aminations, etc.,  lasting  several  days  to  even  a  week.  Although  our  calculations 
have  been  as  careful  as  is  humanly  possible,  and  our  decisions  logical,  mistakes  often 
creep  in;  for  example,  the  child  is  too  large  to  come  through,  or  it  is  too  small  to 
live  after  being  born.  Accidents  also  complicate  the  process;  for  example,  the  posi- 
tion and  presentation  are  unfavorable,  the  cord  prolapses,  the  nervous  condition 
of  the  patient  requires  interference  before  the  os  is  open,  fever  arises,  which  forces 
our  hand,  or,  indeed,  the  child,  while  large  enough,  is  atelectatic  or  deformed,  so 
it  cannot  live.  All  these  conditions  have  been  observed  by  the  author  and  have 
much  reduced  his  enthusiasm  for  the  induction  of  premature  labor  in  contracted 
pelves,  though  he  occasionally  still  performs  it. 

If  the  family  elects  the  induction  of  premature  labor  as  being  less  dangerous, — 
and  in  private  practice  they  usually  do  choose  it, — the  accoucheur  has  to  decide 
on  the  right  time  to  begin  it.  A  period  must  be  selected  when  the  child  is  not  too 
large  to  pass  through  the  pelvis  and  yet  developed  enough  for  extra-uterine  exist- 
ence. The  best  time  is  between  the  thirty-second  and  thirty-fourth  week.  After 
the  thirty-sixth  week  the  child  is  too  large;  before  the  thirtieth  week  its  chances  of 
survival  are  poor.  Added  to  the  difficulties  of  determining  the  exact  period  of 
pregnancy — and  errors  of  three  weeks  either  way  are  not  uncommon — is  the  fact 
that  some  children  develop  faster  than  others,  and  are  as  large  at  eight  months  as 
the  others  are  at  term.  My  practice,  in  cases  set  aside  for  premature  labor,  is  as 
follows:  The  date  of  conception  is  fixed  as  accurately  as  possible,  using  the  dates  of 
menstruation,  coitus,  and  quickening  as  a  basis.  At  the  sixth  month,  and  every 
two  weeks  thereafter,  the  child  is  carefully  palpated  and  measured  (p.  267).  If, 
as  the  thirty-third  week  approaches,  the  child  is  found  to  be  getting  too  large  to 
pass  through  the  pelvis,  labor  is  started.  If  possible,  the  day  is  selected  which 
would  correspond  to  the  time  of  the  menstrual  period,  because  at  such  periods  the 
uterus  is  more  sensitive  and  reacts  quicker  to  stimulation.  Miiller's  procedure — 
pressing  the  head  into  the  pelvis  to  see  if  it  can  enter — has  proved  valueless  in  my 
hands.  The  women  will  not  tolerate  the  small  amount  of  pain  thus  caused,  and, 
further,  the  soft  parts  may  prevent  the  engagement  of  a  head  which  a  few  labor 
pains  can  force  through  very  easily.  The  decision  as  to  the  right  time  to  begin  is 
one  of  experience,  and  everything  depends  on  the  judgment  of  the  accoucheur. 


TREATMENT  OF  CONTRACTED  PELVIS  715 

In  primiparse  laljor  is  seldom  induced,  since  I  prefer  to  see  what  the  woman  can 
accomplish  at  term;   in  multiparse,  the  early  operation  is  often  performed. 

OUiver,  about  1858,  recommended  symphysiotomy  in  pregnane}',  to  provide  the  enlarge- 
ment of  the  pelvis  for  delivery,  and  Frank  practised  it  shortly  before  term.     It  is  not  advisable. 

Prochownick's  Diet. — By  reducing  the  carbohydrates  and  fluids  ingested  during  the  last  two 
months  of  pregnancy  Prochownick  hoped  to  restrain  the  growth  of  the  child,  and  also  to  retard 
the  ossification  of  its  bones,  so  that  it  would  mold  through  the  pelvis  easier.  The  diet  he  pre- 
scribed is  presented  here,  but  my  few  experiences  with  it  have  been  absolutel}^  negative,  and, 
indeed,  daily  observation  in  other  cases,  for  example,  tuberculosis,  carcinoma,  hv'peremesis 
gra\'idarum,  show  that  the  nutrition  of  the  mother  has  little  effect  on  the  growth  of  the  child, 
which  is,  in  fact,  a  parasite. 

Breakfast. — Small  cup  of  coflfee.     One  ounce  of  toast. 

Dinner. — Small  piece  of  meat  or  fish,  or  an  egg,  a  little  sauce,  a  vegetable  prepared 

with  fat,  lettuce,  a  small  piece  of  cheese. 
Supper. — The  same  with  a  few  slices  of  bread  and  butter  and  a  little  milk. 
Water,  soup,  pastries,  potatoes,  sugar,  and  beer  are  forbidden.     About  one  pint  of  water 
daily  is  allowed. 

Patients  living  on  tliis  dietary  require  constant  medical  supervision.  Xephritics  may  not 
be  put  on  such  a  diet. 

Treatment  of  Moderately  Contracted  Pelves  During  Labor. — In  the  first  stage 
the  question  to  decide  is,  shall  we  interfere  at  once  or  shall  we  await  the  test  of 
labor? — interference  or  watchful  expectancy?  In  primiparse,  when  the  parturient 
is  not  quite  at  term,  in  cases  where  the  child  does  not  seem  very  large,  or  where  the 
pelvic  contraction  is  near  the  upper  limit,  wdth  the  conjugata  vera  9  to  93^  cm., 
and  where  the  probability  of  good  strong  pains  seems  good,  my  advice  is  to  wait 
and  see  what  nature  ^all  accomplish.  The  pains  slowlj^  mold  the  head  into  the 
inlet,  and  disproportion  that  seemed  insuperable  is  finally  overcome,  or  the  head 
forced  so  low  that  it  can  be  easily  extracted  by  the  forceps.  "We  can  hope  for  such 
a  termination  in  75  per  cent,  of  the  cases. 

When  the  conditions  are  the  opposite;  when  the  careful,  complete  examination 
shows  that  the  disproportion  between  the  child  and  the  pelvis  is  one  that  is  not 
likely  to  be  overcome  bj'  the  natural  forces;  if  the  presentation  and  position  are 
bad;  when  the  history  of  previous  labors  is  unfavorable  or  the  general  constitution 
of  the  w^oman  such  that  a  severe  parturition  cannot  be  borne — cesarean  section  is 
the  operation  of  choice. 

If  the  expectant  treatment  is  selected,  an  extraordinary  degree  of  watchfulness 
is  demanded.  The  rupture  of  the  membranes  is  to  be  prevented  by  keeping  the 
patient  on  her  side,  forbidding  bearing-down  efforts,  care  during  internal  examina- 
tions, and  by  the  insertion  of  a  soft  colpeurynter,  not  tightly  filled,  in  the  vagina. 
When  dilatation  of  the  cervix  is  complete,  the  membranes  may  be  allowed  to  rupture 
in  order  to  permit  the  head  to  apply  itself  snugly  to  the  inlet  and  complete  the 
molding  process.  ^Molding  may  begin  in  an  intact  sac.  Should  the  membranes 
rupture  before  the  cervix  is  completely  dilated,  the  colpeurynter — now  preferably  a 
Voorhees  bag  with  flat  top — is  placed  inside  the  cervix.  This  keeps  the  head  from 
exerting  injurious  pressure  on  the  bladder,  prevents  incarceration  of  the  anterior 
lip  of  the  cervix  between  the  head  and  symphysis,  preserves  the  liquor  amnii  left 
in  the  uterus,  strengthens  the  pains,  and  helps  to  dilate  the  cervix.  During  the 
first  stage  an  attempt  may  be  made  to  bring  the  head  into  a  good  position  over  the 
inlet.  For  example,  it  may  be  possible,  by  manually  correcting  a  posterior  or  an- 
terior parietal  bone  presentation,  to  place  the  head  in  a  way  to  enter  the  pelvis 
easily.  By  using  the  crouching  position,  with  one  knee  up,  a  head  which  has  slid 
off  the  inlet  into  one  iliac  fossa  may  be  led  back  over  the  inlet  (Fig.  654).  Hof- 
meier's  impression  of  the  head  from  the  outside  may  also  be  tried,  but  I  have 
never  thus  succeeded  in  accomplishing  any  real  results.  It  is  not  entirely  safe. 
The  hands  may  bruise  the  lower  uterine  segment  or  compress  the  cord  lying  around

THE    PATHOLOGY    OF    LABOR 


the  neck.  Xaturally,  in  such  prolonged  laI)ors,  and  with  so  frequent  vaginal 
manipulations,  the  dangers  of  infection  are  increased.  Special  attention  must 
be  paid  to  the  bowels,  since  a  full  rectum  may  prevent  engagement.  The  same  is 
to  be  said  of  the  l)ladder.  Bloody  urine  and  frequent  desire  to  urinate  indicate 
injurious  pressure  on  the  bladder,  which  perhaps  will  result  in  gangrene  and  fistula. 
At  the  end  of  the  first  stage,  and  in  the  beginning  of  the  second  stage,  the  par- 
turient may  be  placed  in  the  Walcher  position  (Fig.  655).  Walcher  discovered  that 
the  conjugata  vera  could  be  leng-thened  l)y  hyperextension  of  the  thighs  Avith  the 
pelvis  fixed.  The  softening  of  the  pelvic  joints  in  pregnancy  permits  the  sacrum  to 
become  movable,  and  by  dropping  the  legs,  for  example,  over  the  edge  of  the  table 
on  which  the  sacrum  is  fixed,  the  innominate  bones  rotate  downward,  enlarging  the 
inlet.     Owing  to  the  oblique  direction  of  the  articular  processes  of  the  sacrum,  this

motion  naturally  causes  the  lower  ends  of  the  innominates  to  approach  each  other 
and  narrow  the  outlet. 

Mercurio,  in  1589,  and  Melli,  in  1738,  used  this  position  to  facilitate  delivery. 
The  true  conjugate  may  be  lengthened  from  6  to  12  mm.,  especially  in  fiat  pelves. 
In  practice  the  woman's  legs  are  warmly  covered,  the  pelvis  brought  to  the  very 
edge  of  the  bed,  and  the  feet  dropped  out  straight  onto  a  soft  pillow.  In  a  few  cases 
I  have  gotten  the  head  to  enter  the  pelvis  by  this  procedure,  but  it  is  very  painful, 
and  few  women  can  he  compelled  to  keep  it  up  over  twenty  to  forty  minutes. 

My  results,  curiously,  have  been  better  })y  the  use  of  the  exaggerated  lithotomy 
position  (Fig.  495,  p.  571),  which  is  theoretically  contraindicated  because  it  contracts 
the  inlet.  The  thighs  force  the  uterus  up,  correcting  the  pendulous  belly  so  com- 
mon with  contracted  pelvis ;  the  uterus  and  child  are  st  raightened  out,  the  former 
being  thus  allowed  to  act  with  more  directness,  and  the  latter  being  brought  into 


TREATMENT  OF  CONTRACTED  PELVIS

better  position  over  the  inlet.  It  is  also  possil)le  that  an  occasional  parietal  bone 
or  ear  presentation  is  corrected.  The  exaggerated  lithotomy  position  may  be  kept 
up  for  several  hours  or  repeated  at  intervals.  When  the  head  projects  into  the 
pelvis  with  a  larg(>  segment,  the  patient  is  instructed  to  bear  down,  to  aid  in  the 
molding.  Three  dangers  must  now  be  watched  for — asphyxia  of  the  child,  ex- 
haustion of  the  mother,  and  rupture  of  the  uterus.  The  advance  signs  of  these 
dangers  will  be  described  in  appropriate  chapters.  How  long  the  parturient  may 
be  allowed  to  labor  depends  on  the  judgment  of  the  accoucheur.  Ever}^  two  or 
three  hours  an  examination  is  to  be  made  to  measure  the  progress,  and  if  there  is  a 
little,  with  none  of  the  three  dangers  impending,  it  is  safe  to  wait.  It  is  unwise  to 
allow  the  second  stage  to  continue  much  over  five  hours  if  the  pains  are  strong  and

the  head  wedged  into  the  inlet.  Fistulas  are  apt  to  result,  and  the  child's  brain 
may  suffer  injury. 

If  spontaneous  labor  does  not  occur,  there  are  four  operations  that  come  up  for 
consideration — version,  followed  by  extraction;  high  forceps;  hebosteotomy;  and 
craniotomy. 

Version  is  performed  only  when  the  head  is  freely  movable,  before  the  lower 
uterine  segment  has  thinned  out  enough  to  invite  the  danger  of  rupture  during  the 
manipulation  and  in  cases  of  abnormal  presentation,  position  and  attitude,  for  ex- 
ample, shoulder,  face,  brow,  anterior  and  ]:)osterior  parietal  ])one  presentation,  and 
prolapse  of  the  cord.  Prophylactic  version  means  version  by  the  breech  during  or 
at  the  end  of  the  first  stage  of  labor  in  contracted  pelves.  The  term  was  introduced 
by  Fritsch.  Simpson  showed  that  the  after-coming  head  passes  through  the  pelvis 
easier  than  when  the  blunt  vertex  precedes.     The  wedge  is  longer,  and  the  head 


718  THE    PATHOLOGY    OF   LABOR 

adapts  itself  better  to  the  inlet.  The  accoueheur  also  has  a  handle  to  pull  on. 
Whether  the  small  amount  of  cerebrospinal  fluid  which  escapes  under  pressure 
from  the  cranium  into  the  spinal  canal  reduces  to  any  extent  the  volume  of  the  head 
is  very  doubtful.  Experience  confirms  the  theory,  but  the  results  are  not  much 
better,  if  at  all,  than  leaving  the  head  to  mold  its  way  through  the  pelvis.  True, 
with  molding  there  are  the  dangers  of  prolonged  cerebral  compression,  fracture 
and  necrosis  of  the  skull,  and  vesicovaginal  and  other  fistulas,  and  peritonitis  in 
the  mother.  On  the  other  hand,  with  prophylactic  version  and  extraction  the  child 
sometimes  suffers  severe  injury  in  being  dragged  quickly  and  forcibly  through 
a  narrow  passage,  and  fracture  of  the  skull,  separation  of  the  occipital  plate  from 
the  condyles,  intracranial  hemorrhage,  disruption  of  the  cervical  vertebrae,  fracture 
of  the  clavicles  and  humeri — all  these  and  more  have  repeatedly  occurred. 

Pare,  in  1585,  recommended  version  in  contracted  pelvis,  but  this  was  before 
the  invention  of  the  forceps,  and  today,  while  used  occasionally,  it  is  giving  way  to 
expectancy  followed  ]:)y  pubiotomy,  or  high  forceps  and  craniotomy.  In  primiparte 
with  contracted  pelvis  version  is  contraindicated,  the  rigidity  of  the  soft  parts 
usually  defeating  all  attempts  to  save  the  baby,  and  deep  and  dangerous  lacerations 
almost  always  resulting. 

Version  may  be  useful  in  multipara  with  weak  pains,  or  those  who  will  not 
work,  or  when  an  indication  on  the  part  of  the  mother  or  child  arises  which  demands 
immediate  delivery.  If  version  is  attempted,  one  must  be  prepared  to  perform 
craniotomy  on  the  after-coming  head,  because  if  it  does  not  come  through,  this  is 
the  onl}'  alternative.  It  has  been  suggested  to  place  the  hebosteotomy  saw  around 
the  bone,  then  to  perform  the  version,  and,  if  in  the  extraction  the  head  is  arrested, 
to  cut  open  the  pelvis.  This  suggestion  has  obtained  little  recognition,  and  does 
not  appeal  to  me.  On  the  other  hand,  when  forceps  are  applied  and  fail,  we  have 
another  operation  which  may  save  the  child — hebosteotomy.  This  is  an  argument 
against  version  in  contracted  pelvis.  Version  and  the  forceps  are  not  competing 
operations.  When  the  conditions  for  forceps  exist,  version  is  contraindicated.  The 
results  for  the  mother  and  babe  are  about  the  same  in  the  two  operations,  and,  the  re- 
fore,  individual  preference  will  determine  the  selection. 

The  Forceps. — When  the  head  has  molded  so  that  it  seems  about  ready  to 
slip  down  into  the  pelvis  and  the  powers  give  out,  or  another  indication  arises  to 
terminate  labor,  the  forceps  may  be  employed.  The  instrument  is  brutal — it 
overcomes  resistance  with  force,  and  in  all  cases  either  the  mother  or  the  babe, 
or  both,  suffer.  Before  beginning  the  operation  the  family  must  be  advised,  first, 
that  the  instrument  is  applied  as  a  matter  of  trial,  an  experiment,  and,  second, 
that  if  it  fails  they  must  decide  whether  hebosteotomy  or  craniotomy  should  follow. 
Pinard,  in  Paris,  Schauta,  in  Vienna,  and  Kronig,  in  Freiburg,  insist  that  the  selec- 
tion of  the  operation  is  not  the  right  of  the  patient  or  her  family,  but  solely  of  the 
accoucheur.  In  most  countries,  to  perform  any  operation  on  another  person  with- 
out his  consent,  even  to  save  his  life,  is  a  tort.  Further,  the  right  of  a  mother  to  re- 
fuse to  endanger  herself  for  the  child  should  be  self-evident.  The  physician  can  and 
should,  in  favorable  cases,  throw  the  weight  of  his  influence  to  save  the  child,  and 
very  few  families  will  refuse  to  follow  his  advice.  Preparations  are  made  for  both 
operations.  When  the  patient  is  anesthetized,  a  complete  examination  will  deter- 
mine if  the  forceps  offer  any  hope  of  success.  If  they  do,  a  few  traction  efforts, 
certainly  not  over  three,  will  demonstrate  it.  Failing  the  forceps,  hebosteotomy 
should  follow  if  the  child  is  in  prime  condition,  and  craniotomy  if  it  is  not.  The 
operation  is  termed  high  forceps,  and  carries  with  it  a  fetal  mortality  ranging  from 
15  to  40  per  cent.,  and  a  maternal  mortality  of  2  to  4  per  cent.  Much  confusion 
exists  as  to  the  exact  definition  of  "  high  forceps."  Most  authors  apply  it  to  the  use 
of  forceps  when  the  largest  circumference  of  the  head  has  not  yet  passed,  but  is 
just  about  to  pass,  the  region  of  the  inlet,  and  this  seems  the  best  to  me.     Some

writers  wish  the  term  high  to  mean  the  head  fully  above  the  inlet;  some,  on  the 
other  hand,  call  the  operation  high  after  the  head  has  engaged,  but  has  not  yet 
reached  the  second  parallel  plane  of  Hodge.  The  difficulty  of  appraising  the  values 
of  statistics  offered  for  the  operation  is  thus  made  apparent,  because  the  dangers  of 
the  various  operations  are  vastly  different. 

In  flat  pelves,  after  the  head  has  passed  the  inlet,  delivery  is  usually  easily 
accomplished,  either  by  the  natural  powers  or  by  the  use  of  forceps,  and  the  dangers 
to  the  mother  and  babe  are  very  slight.  In  generally  contracted  and  in  funnel 
pelves  the  trouble  is  not  over  when  the  head  is  engaged— it  may  begin  at  this  point, 
and  if  spontaneous  delivery  does  not  occur,  the  worst  forms  of  dystocia  may  result. 
The  forceps  here  are  equal  almost  to  the  old-fashioned  cephalotribe;  the  child  often 
dies,  is  always  seriously  injured,  and  the  mother  never  escapes  without  extensive 
damage.  It  is  ail  the  more  important,  therefore,  for  the  accoucheur  to  determine 
the  nature  of  the  pelvis  with  which  he  has  to  deal,  and  avoid  forceps  and  version 
in  those  with  general  or  funnel  contraction.  Cesarean  section  and  hebosteotomy — 
the  latter  rarelv — come  more  to  the  front  in  these  conditions.

The  area  of  inlet  is  augmented  about  50  per  cent.     Note  how  the  head  may  utiUze  the  gap  between  the  severed  bones. 


Symphysiotomy  and  Hebosteotomy,  or  Pubiotomy. — By  cutting  the  pelvic 
girdle  it  is  possible  to  enlarge  the  pelvic  cavity  in  all  its  diameters.  If  the  pelvic 
joints  are  loosened  more  than  usual,  the  enlargement  is  very  marked.  Section  at 
or  near  the  pubis  allows  the  bones  to  separate  2  or  2}/^  cm.,  and  when  the  head  passes 
through,  they  part  even  6  or  7  cm., — the  latter,  however,  not  without  some  danger 
to  the  sacro-iliac  joints.  The  innominates  roll  cloAraward  and  outward,  but  the 
separation  of  the  lower  portions  is  less  than  in  the  upper,  hence  the  operation  is 
not  so  useful  in  contraction  of  the  outlet.  With  a  separation  of  6  cm.  the  conjugata 
vera  lengthens  1  to  13^  cm.,  the  transversa  2.5  to  3  cm.,  and  the  obliques  about  same. 
An  important  gain  in  space  is  obtained  by  the  anterior  parietal  bone  fitting  into  the 
gap  between  the  divided  ends  of  the  ramus  pubis.  In  flat  pelves  the  greatest  gain  is 
obtained  (Fig.  656).  Section  of  the  s^anphysis  pubis  (symphysiotomy)  has  been  re- 
placed almost  entirely  by  the  Stolz-Gigli  operation  of  pubiotomy,  or,  more  correctly, 
hebosteotomy,  the  salving  through  of  the  ramus  pubis  alongside  the  joint.  The  gain 
in  space  is  the  same  with  the  two  operations  (Cusmano).     SjTnphysiotomy  had  a

mortality  varying  from  3  to  12  per  cent,  for  the  mothers,  and  9  to  19  per  cent,  for  the 
children,  and,  taking  the  results  of  nine  of  the  best  operators  together,  6.78  per  cent, 
for  the  mother  and  10. G  per  cent,  for  the  children.  At  the  operation  severe  hemor- 
rhage from  the  wound,  particularly  when  there  were  varicose  veins,  extensive  injury 
of  the  anterior  vaginal  wall  and  the  perineum,  tearing  of  the  levator  ani  from  the  rami 
pubis,  the  lacerations  communicating  with  the  joint,  tearing  of  the  bladder  and 
urethra,  overstretching  of  the  sacro-iliac  joints,  with  rupture  of  their  anterior  liga- 
ments, hematoma  around  the  joint  (more  with  hebosteotomy),  were  reported  \^'ith 
great  frequenc}-.  In  a  few  cases  bony  union  of  the  pubis,  requiring  the  saw,  and  anky- 
losis of  the  sacro-iliac  joints,  necessitating  final  resort  to  craniotomy  and  cesarean 
section,  were  met.  Convalescence  was  frequently  interrupted  and  prolonged  by  in- 
fection of  the  wound  and  pyemia,  because  of  poor  drainage,  the  poor  healing  qualities 
of  the  cartilaginous  joint,  the  ])roximity  of  the  septic  vagina,  and  the  frequent  com- 
munications with  it.  Hematomata;  thrombosis  in  the  veins  and  embolism;  slow 
healing  of  the  joint,  with  prolonged  sickness  in  bed  and  difficulty  of  locomotion  later 
(in  two  of  the  author's  cases  locomotion  was  impaired  two  and  eight  months  respec-

tively);  loss  of  control  of  the  bladder;  descensus  and  prolapse  of  the  uterus;  dislo- 
cation and  distortion  of  the  base  of  the  bladder  and  deforming  scars  of  the  soft  parts; 
and  hernia  between  the  bones  were  other  accidents  and  sequclse.  The  union  of  the 
joint  was  never  bony,  but  after  several  months  a  sufficient  degree  of  firmness  was  at- 
tained. A  good  feature  of  this  fibrous  union  of  the  joint  became  evident  in  sul^se- 
quent  labors.  The  softening  and  relaxation  of  the  symphysis  were  so  great  that 
spontaneous  delivery  was  allowed.     This  occurred  in  two  of  my  cases. 

Hebosteotomy  aims  to  avoid  some  of  these  dangers,  and,  indeed,  the  mortality 
is  less  for  the  mother,  though  about  the  same  for  the  child,  and  the  morbidity  is 
less.  Since  the  cut  in  the  bony  ring  is  made  at  the  side  of  the  joint,  the  structures 
around  the  latter,  the  urethra,  the  bladder,  the  clitoris,  the  large  venous  plexuses, 
etc.,  are  a  little  less  liable  to  injury.  It  is  said  that  by  making  the  operation  prac- 
tically subcutaneous,  the  danger  of  infection  is  lessened;  tears  communicating 
with  the  vagina  are  rarer;  severe  hemorrhage  is  rare;  the  operation  requires  less 
skill  (?) ;    convalescence  is  quicker  and  simpler. 

Schlafli,  in  1908,  reported  700  hebosteotomies  with  a  maternal  mortality  of 
4.96  per  cent,  and  a  fetal  of  9.18  per  cent.,  but  individual  operators  (Williams, 
Stoeckel)  have  had  series  of  25  and  24  cases  without  a  maternal  death  (Roemer).

Operators  of  the  largest  experience  have  discarded  hebosteotoniy  in  primiparse, 
and  will  not  perform  it  in  cases  complicated  by  heart  and  kitlney  diseases,  infection 
of  the  parturient  canal,  extreme  obesity,  colossal  varicosities  of  the  genitals,  and 
extremely  large  child. 

On  the  Continent  the  enthusiasm,  which  reached  its  acme  at  the  Dresden 
Congress  of  German  Gynecologists,  .has  undergone  a  complete  reversal,  and  at  the 
Strasbourg  Congress  a  few  years  later  not  a  voice  was  raised  for  hebosteotomy. 

While  the  mortality  is  not  very  high,  the  bladder  and  urethral  injuries,  the 
hemorrhage  from  the  wound,  the  hematomata,  the  extensive  lacerations,  the 
frequency  of  fever  in  the  puerperium,  of  thrombosis  of  the  pelvic  and  crural  veins, 
the  delayed  convalescence,  and  the  troubles  of  locomotion  (more  frequent  than 
reports  show)  explain  the  loss  of  popularity  of  the  operation.  IVIy  o^\^l  experience 
with  both  operations  is  small,  and  while  none  of  the  mothers  or  babies  died,  the 
impressions  of  them  are  not  encouraging  for  further  experiment.  Lately  successful 
series  have  been  reported  I:)}"  Stockel,  Williams,  and  a  few  English  and  American 
accoucheurs,  and,  without  doubt,  the  operation  has  been  too  quickly  condemned. 
Performed  under  proper  restrictions,  for  the  correct  indication,  and  by  a  competent 
accoucheur,  it  will  hold  a  permanent  place  in  obstetric  surgery.  In  general,  its 
field  will  be  limited  to  pelves  having  a  true  conjugate  of  not  less  than  7.5  cm.  when 
the  conditions  for  cesarean  section  are  not  ideal. 

When,  in  a  multipara,  in  a  case  of  the  type  under  consideration, — of  moderate 
pelvic  contraction, — expectancy  has  shown  that  the  head  is  too  large  to  go  through 
spontaneously,  and  a  gentle  trial  with  the  forceps  has  proved  the  disproportion  to  be 
greater  than  was  expected,  heljosteotomy  is  the  operation  of  choice,  provided  both 
mother  and  child  are  in  good  condition.  The  best  time  for  cesarean  section  is  gone 
Ijy,  but  the  section  of  the  pubis  offers  excellent  chances  of  saving  the  two  patients. 
This  is  an  advantage  of  pubiotomy — it  enables  us  to  subject  the  woman  to  the  test 
of  lal)or. 

Extraperitoneal  Cesarean  Section. — This  is  an  operation  with  an  incision  just 
above  the  pubis,  by  which  access  is  gained  to  the  lower  uterine  segment  and  the 
child  delivered  without  entering  the  peritoneal  cavity.  (See  p.  1000  for  details.) 
The  reception  the  new  operation  got  in  1907,  1908,  and  1909  was  very  enthusiastic, 
because  the  hope  was  revived  that  at  last  it  would  be  possiljle  to  do  away  with 
craniotomy  on  the  living  child  when  the  conditions  were  not  good  for  the  classic 
cesarean  section.  Experience,  however,  has  shown  that  these  dangers  beset  the  new 
operation :  (1)  The  peritoneum  is  sometimes  opened  unintentionally ;  (2)  the  bladder 
is  sometimes  torn;  (3)  hemorrhage  from  the  veins  may  be  alarming;  (4)  the  im- 
mense space  in  the  connective  tissue  is  liable  to  hematoma  formation  or  infection, 
with  abscess,  which  ma}'  break  into  the  peritoneal  cavity;  (o)  throml)osis  of  the  im- 
mense veins  laid  bare  and  embolism;  (6)  infection  and  peritonitis,  the  thin  layer  of 
peritoneum  not  offering  an  efficient  barrier;  (7)  difficulty  of  tcchnic;  (8)  subsequent 
labors  bring  the  danger  of  rupture  of  the  uterus,  the  scar  being  in  the  thinnest 
portion,  and  that  which  is  distended  during  the  formation  of  the  parturient  canal; 
(9)  retroversio  uteri  is  common;  (10)  the  fetal  mortality  is  high.

722  THE    PATHOLOGY    OF    LABOR 

It  is  settled  that  the  operation  should  not  be  performed  on  infected  cases  (foul 
liquor  anniii,  fever,  rapid  pulse,  gray  exudate  on  vulvar  wounds),  and  the  procedure 
is  nearl}'  as  certainly  contraindicated  when  infection  is  suspected  (dirty  midwives, 
prolonged,  exhausting  labor,  attempts  at  delivery  by  questionable  hands).  Under 
these  circumstances  even  hebosteotomy  is  too  dangerous.  There  is  a  field  now 
claimed  by  hebosteotomy  where  labor  has  advanced  to  a  point  which  demonstrates 
that  the  head  will  not  enter  the  contracted  pelvis.  Dilatation  is  complete,  the 
lower  uterine  segment  drawTi  up,  and  the  case  clean.  Our  advice  is  trial  of  the  for- 
ceps, followed  by  hebosteotomj^  or  craniotomy,  if  exacted ;  but  several  recent  writers 
urge  the  extraperitoneal  or  the  suprasymphyseal  transperitoneal  cesarean  section. 
It  is  too  early  to  decide,  but  at  the- present  writing  l)oth  operations  are  losing  favor. 
Early  in  labor,  as  a  primary  operation,  the  classic  cesarean  section  is  still  the  oper- 
ation of  choice  as  against  its  modifications. 

Craniotomy. — When  the  child  is  dead,  craniotomy  should  be  performed  as 
soon  as  the  cervix  is  large  enough  to  permit  it.  If  the  child  is  djdng,  or  if,  in  the 
judgment  of  the  accoucheur,  its  life  has  been  compromised  bj^  prolonged  compres- 
sion in  labor,  or  it  has  been  damaged  by  attempts  with  forceps  or  version,  craniot- 
omj'  should  be  done.  The  accoucheur  may  not  plume  himself  on  the  success  of 
having  delivered  the  child  alive,  when  it  succumbs  in  a  few  hours  or  a  few  days 
to  the  results  of  labor.  The  mother  has  invariably  suffered  severe  injury,  and  has 
often  been  killed  by  the  forced  delivery,  and  these  accidents  must  be  charged  against 
the  attendant.     Craniotomy  is  much  safer,  and  the  end-result  for  the  baby  the  same. 

With  the  child  in  good  condition,  craniotomy  should  be  the  rarest  of  all  oper- 
ations, but — and  practically  all  authors  agree — a  few  conditions  arise  wdiere  it 
must  be  resorted  to  as  the  ultimate  refuge:  (1)  If  the  patient  absolutely  refuses 
to  incur  any  danger  to  herself  for  the  sake  of  the  infant.  The  operation  is,  however, 
not  to  be  repeated  in  a  subsequent  labor.  (2)  If  labor  has  been  prolonged  and 
infection  is  positively  or  possibly  present.  (3)  Where  expectancy  and  high  forceps 
have  failed  and  the  conditions  are  not  good  for  hebosteotomy — for  example,  an 
ankylotic  pelvis,  immense  varicosities  of  the  vulva,  extreme  obesity  of  the  patient. 

IV.  Treatment  of  Labor  in  Pelves  only  Slightly  Contracted. — Pelves  Contracted 
at  the  Inlet. — In  pelves  with  a  conjugata  vera  of  9^^  to  11  cm.  labor  almost  always 
terminates  spontaneously,  unless  the  child  is  very  large,  in  which  case  the  pelvis 
is  thrown  back  into  the  class  of  the  ''moderately"  contracted,  just  considered. 
Variations  in  the  mechanism  of  labor,  however,  are  very  common,  and  the  cause 
for  breech,  face,  brow,  and  shoulder  presentations,  for  occipitoposterior  and  other 
malpositions,  and  for  errors  of  attitude,  as  prolapse  of  the  cord,  the  hand,  etc.,  is 
often  to  be  found  in  a  slight  pelvic  contraction  Avhich  would  otherwise  pass  un- 
noticed. Operative  deliveries,  which  in  normal  pelves  would  be  simple,  easy,  and 
typical,  become,  when  slight  contraction  exists,  unexpectedly  and  unexplainedly 
difficult  and  complicated.  When  dystocia  arises  in  such  a  pelvis,  the  treatment  is 
the  same  as  that  just  described. 

Pelves  Contracted  at  the  Outlet. — As  a  rule,  the  obstruction  offered  by  the 
narrow  bony  outlet  is  not  recognized  until  the  head  has  been  arrested  at  this  point 
for  several  hours,  and  often  the  forceps  are  applied  in  ignorance  of  true  conditions. 
Engagement  of  the  head  is  the  rule,  unless,  in  addition  to  a  narrow  outlet,  the 
pelvis  is  roofed  over  by  a  projecting  spinal  column,— pelvis  obfecta, — as  in  the 
kyphotic,  and  the  spondylolisthetic  forms.  It  is  wise,  before  every  forceps  opera- 
tion, to  measure  the  distance  between  the  tuberosities  and  see  how  far  the  sacrum 
and  the  coccyx  encroach  on  the  anteroposterior  diameter  of  the  outlet. 

If  the  anomaly  is  discovered  in  pregnancy  or  early  in  labor,  what  was  said 
under  the  general  heading  applies  here  also.  If  it  is  found  only  after  dystocia  is 
manifest,  the  following  is  sugg(!sted:  (1)  The  exaggerated  lithotomy  position, 
recommended  by  the  author  more  than  twelve  years  ago  (Fig.  495,  p.  571).     This-

opens  the  bony  outlet  and  often  produces  enough  enlargement.  Experiments  on 
the  cadaver  show  a  gain  of  33^  to  5  mm.  in  the  transverse  diameter,  and  also,  accord- 
ing to  Williams,  decided  enlargement  of  the  anteroposterior.  (2)  Jonge's  position, 
the  same  but  with  the  legs  extended  (Fig.  658),  is  said  to  enlarge  the  outlet  still 
more — even  9  mm.  Krug  suggested  pulling  the  tul)erosities  apart  directly  with  the 
hands.  (3)  Prolonged  expectancy — but  during  the  period  of  molding  the  possibility 
of  pressure  necrosis  of  the  maternal  parts  and  injury  to  the  brain  of  the  fetus  must 
be  borne  in  mind.  (4)  The  forceps — in  mild  degrees  of  contraction  this  instrument 
will  usually  succeed,  but  a  large  number  of  babies  are  killed  by  the  operation,  and 
the  mother  almost  always  suffers  severe  lacerations,  which  may  extend  through  the

vaginal  walls  mto  the  ischiorectal  fossa  and  down  to  the  bone.  In  one  case  it  was 
possible  to  put  the  hand  into  a  wound  which  extended  up  into  the  false  pelvis, 
the  soft  parts  having  been  dragged  off  their  pelvic  attachments.  Rupture  of  the 
symphysis  pubis  has  been  frequently  reported,  and  occurs  oftener  than  published. 
If  the  child  is  in  good  condition  when  the  first  real  difficulties  of  the  operation  are 
experienced,  hebosteotomy  is  the  operation  of  choice;  if  it  is  not  in  good  condition, 
craniotomy  is  to  be  done.  Primiparae  suffer  the  worst  from  this  anomaly.  In 
multipane,  the  resistance  of  the  soft  parts  being  absent,  a  small  amount  of  outlet 
contraction  may  cause  little  trouble — indeed,  may  pass  unnoticed. 

Complicated  Labors  in  Contracted  Pelves. — Labors  complicated  by  abnormal 
presentations  and  attitudes  of  the  child  require  many  modifications  in  the  treat- 
ment.    In  breech,  shoulder,  brow,  and  face  presentations  it  is  impossible  to  await 


724  THE   PATHOLOGY    OF   LABOR 

the  test  of  labor  and  also  to  fit  the  head  to  the  pelvis  as  we  do  in  vertex  presentations. 
It  is,  therefore,  necessary  to  estimate  the  degree  of  spacial  disproportion  from  the 
pelvic  measurements  and  the  adjudged  size  of  the  child.  The  choice  of  the 
operation  will  lie  between  prophylactic  version,  cesarean  section,  and  hebosteot- 
omy.  \'on  Franque  suggested  applying  the  hcbostcotomy  saw  provisionally 
around  the  joint,  to  perform  extraction,  or  version  and  extraction  as  indicated,  and, 
if  the  after-coming  head  is  arrested  at  the  inlet,  the  bone  could  be  immediately 
sawn  through  and  delivery  thus  quicklj^  effected  in  time  to  save  the  infant.  This 
is  an  ingenious  suggestion,  but,  in  my  opinion,  impractical  and  dangerous.  If 
hebosteotoni}'  is  to  be  done  at  all,  it  should  be  the  primary  operation.  Version  is 
particularlj'  unfavorable  to  the  child,  because,  unless  the  narrowing  of  the  passage 
is  very  slight,  the  after-coming  head  will  be  stopped  at  the  inlet,  the  infant  will  die, 
and  craniotomy  will  have  to  be  performed.  Therefore,  in  breech,  shoulder,  and 
deflexion  presentations,  unless  the  accoucheur  is  convinced  that  the  child  will  go 
through  the  pelvis,  cesarean  section  should  be  performed  as  a  primary'  operation — 
given,  of  course,  good  conditions. 

Placenta  prsevia  complicating  contracted  pelvis  demands  cesarean  section  if 
the  child  is  alive,  and  craniotomy  if  it  is  dead.  It  is  doubly  dangerous  to  drag  a 
large  child  forcil^ly  through  the  thinned  lower  uterine  segment.  Aloruptio  placenta3 
demands  cesarean  section  if  the  cervix  is  closed.  Even  rigid  soft  parts  may  render 
the  abdominal  delivery  safest. 

Eclampsia  seems  to  be  a  little  more  frequent  in  contracted  pelvis.  It  also  makes 
cesarean  section  more  readily  chosen,  and  the  same  may  be  said,  speaking  broadly, 
of  all  other  complications  requiring  rapid  delivery. 

Hospital  versus  Home  Practice.— The  foregoing  presentment  of  the  subject 
gives  the  treatment  of  contracted  pelvis  in  the  author's  own  and  hospital  practice. 
Without  question  great  differences  in  treatment  must  exist  between  that  of  the 
specialist,  aided  by  maternity  facilities,  and  that  of  the  general  practitioner,  caring 
for  his  patient  in  a  flat,  or  a  farm-house,  or  even  a  ''lean-to,"  with  no  help  but  a 
nurse  or  the  neighbors.  In  cities  and  towns  the  parturient  can  and  should  be  trans- 
ported to  a  well-equipped  maternity,  but  under  the  conditions  surrounding  the 
birth  of  the  majority  of  children  this  is  seldom  practicable,  and,  unless  the  mater- 
nity facilities  can  be  closely  imitated  in  the  home,  the  accoucheur  will  have  to  adapt 
his  treatment  to  the  environment  he  finds.  This  is  particularly  unfortunate  for  the 
child,  because  cesarean  section  and  hebosteotomy  are  very  dangerous  performed 
under  such  conditions,  and,  therefore,  inadvisable. 

Prolonged  expectancy  is  the  best  treatment  for  all  but  the  absolutelj'  contracted 
pelves,  followed  by  a  trial  with  the  forceps,  failing  which  craniotomy  is  the  horrible 
ultimate.  If  the  head  is  movable,  or  if  the  presentation  and  attitude  are  abnormal, 
version  is  indicated.  A  high  infant  mortality  is  to  be  expected,  but  the  informa- 
tion gained  will  warn  the  attendant  to  provide  ideal  arrangements  for  subsequent 
labors,  and,  in  the  end,  a  larger  number  of  children  will  be  saved  than  if  the  attend- 
ant tries  to  force  the  conditions  in  a  bad  environment.  The  same  statement  should 
apply  to  prolonged  and  brutal  attempts  at  delivery  with  the  forceps.  A  short  trial 
will  convince  the  operator  that  they  are  powerless  to  effect  delivery,  and  if  the  trac- 
tions are  persisted  in,  they  can  result  only  in  irreparable  damage  to  the  mother,  and 
the  object  sought,  a  living  child,  is  almost  always  defeated  by  the  attempt  itself. 
Craniotomy  is  more  humane.  A  careful  study  of  his  pregnancy  cases  will  enable 
the  accoucheur  to  foresee  the  above  dangers,  and,  by  proper  provision,  avoid  them.

THE  ACCIDENTS  OF  LABOR 

Injuries  to  the  Parturient  Canal 
the  vulva 

All  primiparse  and  many  multiparsG  suffer  from  injuries  of  the  parturient 
canal.  These  are  generally  considered  normal,  but  why,  the  author  cannot  under- 
stand— no  other  function  of  the  body  is  always  attended  by  injury.  In  primiparse 
the  most  frequent  lesions  are  found  about  the  vulvar  orifice.  Fig.  659  shows  the 
most  common  vulvar  lacerations.  They  are  seldom  deep,  but  if  they  involve 
important  structures,  serious 
results  may  follow.  If  the  tear 
extends  through  a  crus  of  the 
clitoris,  or  even  through  the 
organ  itself,  severe  and  even 
fatal  hemorrhage  may  ensue. 
If  a  varicose  vein  is  opened, 
the  patient  may  die  from  loss 
of  blood.  If  the  duct  of  the 
gland  of  Bartholin  is  torn 
across,  a  cyst  may  form.  If 
the  urethra  is  involved,  a 
stricture  may  follow.  These 
wounds  often  become  the  seat 
of  puerperal  ulcers,  and  if  the 
infection  is  virulent  or  the 
woman's  resistance  low,  inva- 
sion of  the  connective  tissue, 
even  general  septicemia,  may 
be  the  outcome.  These  lesions 
are  often  associated  with  vag- 
inal tears.  Superficial  wounds 
— simply  si)litting  the  skin  and 
mucosa — require  suturing  but 
seldom,  since  their  edges  usu- 
ally lie  in  apposition  when 
the  legs  are  brought  together. 
Hemorrhage  from  clitoris  tears 
and  those  involving  varicose 
veins  is  easily  stopped  tempo- 
rarily by  pressure  between  the  finger  and  thumb,  or  by  a  gauze  .sponge,  and  perma- 
nently l)y  a  draw-string,  fine  catgut  suture  through  the  base  of  tiie  wound.  Often 
compression  is  enough.     Frenulum  tears  should  be  sutured. 

Rupture  of  the  urogenital  septum  is  an  inevitable  injury  in  labor,  and  it  can- 
not be  fully  repaired.  Some  relaxation  and  descensus  of  the  anterior  vaginal  and 
urethral  wall  is  an  invariable  sequence,  and  it  not  seldom  leads  to  a  slight  catarrh 
at  the  neck  of  the  bladder — the  so-called  "irritable  bladder"  of  the  older 
writers.     During  labor  attempts  to  push  the  protruding  urethra  back  out  of  the

way  of  the  advancing  head  always  fail,  and  the  urethra  is  wiped  off  its  pubic 
attaclnnents. 

THE  PERINEUM  AND  PELVIC  FLOOR 

If,  with  the  index-finger  in  the  rectum  and  the  thumb  in  the  fourchet,  the 
perineal  body  be  squeezed  together,  the  examiner  will  be  surprised  to  find  how  very 
little  tissue  there  is  in  it.  Indeed,  it  is  composed  only  of  a  little  fat  and  connective 
tissue, — the  centrum  tendineum,^ — ^vith  the  rudimentary  muscles,  the  constrictores 
cunni,  the  musculi  bulbi  cavernosi,  a  few  levator  ani  fibers,  and  the  transversus 
perinei.  The  fingers  will  easily  outline  the  sphincter  ani,  the  important  closing 
muscle  of  the  rectum.     Lacerations  of  the  perineal  body  occur  in  the  majority  of 


Pubococcygeus  portion.

primiparous  labors,  and  while  they  have  considerable  importance,  it  is  decidedly 
less  than  tears  of  the  pelvic  floor — of  the  levator  ani  and  the  fascia  in  which  it  is 
set.  When  the  perineal  body  is  torn,  the  urogenital  septum  is  destroyed,  the  ante- 
rior wall  of  the  vagina  sags,  the  posterior  vaginal  wall  begins  to  roll  out,  and  the 
vulva  is  permanently  open,  inviting  infection,  which  almost  always  results  in  a 
vaginal  and  cervical  catarrh.  Late  effects  are  descensus  uteri  and  chronic  metritis. 
If  the  tear  is  deeper,  it  may  involve  part  or  all  the  sphincter  ani,  or  even  run  up 
the  rectal  wall  more  or  less.  I  have  seen  the  rectum  torn  for  a  length  of  three  inches 
beyond  the  sphincter.  Complete  incontinence  of  feces  is  the  first  effect  of  such 
tears,  but  if  they  are  not  so  extensive  and  the  levator  ani  is  not  seriously  injured, 
the  latter  muscle  assumes  vicarious  control  of  the  bowel,  and  the  patient  may  be 
able  to  hold  the  hard  feces.  Soft  feces  and  gas,  however,  will  usually  pass  off  in 
spite  of  the  woman's  efforts. 

The  levator  ani  is  always  injured  in  labor.     Either  it  is  overstretched,  which

means  that  there  are  innumerable  microscopic  tears  of  the  muscular  fibers,  or 
some  of  the  muscular  bunfUes  are  torn,  or  there  is  a  deep  laceration  of  one  or  both 
sides  of  the  sling-like  structure.     The  last  kind  of  injury  may  be  discovered  after

labor,  but  the  other  two  usually  pass  unnoticed  because  they  are  unattended  by  a 
laceration  of  the  vagina.  The  latter  is  too  elastic  to  tear,  but  the  muscle  gives  way 
under  the  mucous  membrane.     Such  cases  come  to  the  accoucheur  later  with  the

history  of  no  tear  during  labor,  and  he  diagnoses  them  "relaxation  of  the  pelvic 
floor."  On  several  occasions  I  have  attempted  to  shorten  up  the  stretched  muscle 
after  labor  l)y  deep  sutures  tied  across  the  intact  vaginal  mucous  membrane.  Rare 
instances  of  submucous  laceration  of  the  sphincter  ani  are  on  record. 


728 


THE    PATHOLOGY    OK    LABOR 


Lacerations  of  the  tendinomuscular  jH'lvic  floor  may  be  unilateral  or  bilateral, 
and  the  puboret-tal  portion  of  the  muscle  is  usually  involved.  In  a  lar<ie  number  of 
cases,  I  am  convinced,  the  two  halves  of  the  muscle  separate  at  their  junction  behind 
the  rectum  in,  or  alongside,  the  raphe  which  leads  from  the  coccyx  to  the  anus. 
(See  Fig.  181,  p.  160.)  This  allows  the  anus  to  fall  back  toward  the  coccyx,  and 
leaves  the  two  halves  of  the  levator  as  pillars  on  each  side  of  the  gaping  vagina 
(Fig.  660).  Perfect  anatomic  repair  of  such  a  rupture  is  not  possible  with  our 
present  methods  of  operation.  It  will  be  necessary  to  gain  access  to  the  torn  ends 
of  the  muscle  from  behind  the  rectum. 

Sometimes  the  nuiscle  is  torn  directly  away  from  its  attachments  to  the  pos- 
terior surface  of  the  pul)is  (Fig.  661),  such  injuries  being  usually  the  result  of  forced 
forceps  deliveries,  attended  by  attempts  to  rotate  the  head  with  the  instrument.

Child  emerged  through  rent. 


When  a  tear  of  this  kind  is  extensive,  the  bladder  lies  naked  at  the  top  of  the  wound. 
In  the  lateral  tears  the  mucous  membrane  of  the  vagina  is  also  torn  in  the  sulci, 
and  if  both  sides  are  affected,  the  columna  rugarum  lies,  tongue-shaped,  at  the 
bottom  of  the  wound.  Fig.  662  shows  the  various  forms  of  the  perineal  and  pelvic 
floor  injuries  as  they  appear  after  laljor.     All  the  figures  were  drawn  from  life. 

Etiology. — Perineal  tears  occur  with  a  frequency  varying  from  9  to  34  per  cent., 
as  put  by  dilferent  authors.  Forceps  labors  show  54  to  85  per  cent,  of  tears.  In 
my  own  experience  an.  absolutely  anatomically  intact  perineum  is  a  great  rarity,  l)ut 
extensive  lacerations  are  uncommon,  l:)ecause  I  use  episiotomy  often. 

The  most  common  cause  of  p(>rineal  lacerations  is  disproportion  ])etween  the 
child  and  the  soft  parts — either  the  head  is  too  large  or  the  canal  too  small,  as  occurs 
with  infantile  genitalia,  or  the  head  presents  unfavorable  diameters  to  the  passage,

as  in  occipitoposterior  positions  and  brow  presentations.  Too  rapid  delivery,  either 
spontaneous  or  operative,  by  not  giving  the  parts  time  to  dihite,  causes  many  tears. 
Therefore  we  see  the  most  extensive  injuries  after  extraction  by  the  breech  or  by  for- 
ceps. Sometimes  the  forceps  directly  crush  the  perineum,  or  it  is  torn  by  introduc- 
ing the  hand  alongside  the  l)aby's  body  in  breech  deliveries,  but  these  are  errors  of 
art.  Disease  of  the  soft  parts  nuist  also  be  mentioned ;  edema  from  prolonged  labor; 
excessive  rigidity  from  advanced  age  (old  primipara^);  scars  from  previous  injury; 
sj^hilitic  infiltration;  gonorrhea,  with  or  Avithout  condylomata;  loss  of  elasticity 
from  general  illness  (for  example,  typhoid,  tuberculosis,  etc.),  and  sometimes,  from 
no  apparent  cause,  the  perineum  tears  like  wet  blotting-paper.     It  occurs  to  me 


Fig.  667. — Suturino  the  Rectal  Mucosa. 

With  a  fine  needle  and  No.  0  twenty-daj'  catgut 
the  rectal  mucosa  is  first  closed.  The  needle  enters  and 
issues  on  the  wounded  surface  of  the  rectum,  does  not 
pass  through  into  the  gut,  and  the  knots  are,  therefore, 
all  buried.  The  needle  is  putting  in  the  last  of  the  su- 
tures, which  are  about  0.5  cm.  apart  and  interrupted.  If 
the  tear  is  very  extensive,  a  second  row  is  inserted  to  re- 
inforce the  first.

that  such  a  state  of  the  perineum  may  be  clue  to  a  toxemia,  since  it  is  usually  asso- 
ciated with  hemorrhagic  tendencies  and  al])uminuria. 

An  important  cause  of  perineal  tears  not  generall}'  recognized  is  a  narrow  pubic 
arch.  Unless  the  head  can  occupy  the  space  directly  under  the  subpubic  ligament,  it 
is  forced,  by  the  narrowing  rami  pubis,  doAvnward  toward  the  coccyx,  of  course  thus 
overstretching  the  levator  ani  and  perineum.  We  find,  therefore,  the  most  extensive 
injuries  in  funnel  pelves  and  those  \x\t\\  a  narrow  pulnc  arch.  In  these  cases,  too, 
the  vagina,  around  its  outlet,  being  caught  between  the  head  and  the  ])ones,  is  forced 
or  dragged,  if  the  delivery  is  operative,  downward  and  outward,  and  if,  in  addition  to 
the  other  traumatisms,  rotation  movements  are  made  with  the  forceps,  the  vaginal 
walls  are  torn  completely  off  their  pelvic  attachnunits  and  are  split  in  several  direc- 
tions. 

The  deeper  lacerations,  involving  the  muscles  of  the  pelvic  floor,  take  place

from  within  outward,  first  the  muscle  tearing,  then  the  vagina,  which  is  first  visibly 
spanned  transversely,  and,  finally,  the  skin.  Sometimes  the  skin  is  a})Solutely 
intact,  but  all  the  deeper  structures  down  to  and  exposing  the  rectum  are  torn  apart,

To  insure  broad  apposition  of  the  torn  ends  of  the 
muiscle  the  needle  should  pass  well  to  the  side,  and  two, 
even  three,  sutures  may  be  placed,  one  of  which  should 
unite  the  fascia  surrounding  the  muscle.  This  is  the 
most  important  part  of  the  operation,  and  plenty  of  time 
should  be  spent  on  it.     Xo.  2  twenty-day  catgut  is  used. 


Fig.  671. — Reinforcing  Suture  above  Sphincter  Ani. 
A  finger-cot  or,  better  still,  an  extra  rubber  glove,  is 
drawn  on,  the  index-finger  inserted  into  the  rectum,  and  a 
suture  is  now  pa.ssed  above  the  sphincter  ani  from  the  skin 
surface,  using  silkworm-gut.  This  reinforces  the  catgut  su- 
ture and  brings  together  the  connective  tissue  of  the  centrum 
tendineum.  Sometimes  this  stitch  turns  the  anus  in  a  little, 
hence  the  edges  of  the  skin  where  it  joins  the  mucosa  are 
iinited  by  a  fine  catgut  suture.  The  rest  of  the  operation  is 
like  those  for  incomplete  tear. 


and  in  such  instances  the  superficial  observer  will  fail  to  discover  the  extent  of  the 
injury,  and  may  even  declare  that  no  lacerations  exist.  In  these  cases  I  have 
found  it  best  to  incise  the  thin  bridge  of  skin  medially  the  whole  length  of  the 
wound,  which  gives  better  access  to  the  deeper  structures  for  suturing.     The

vagina  tears  in  one  or  both  of  the  sulci,  and  the  wound  may  extend  up  ])eyond  the 
spine  of  the  ischium,  even  untler  the  l)road  Hgament.  Tiie  suix'rficial  lacerations — 
those  of  the  perineal  botly  alone — usually  occur  with  normal  labors,  or  forceps 
deliveries  after  the  head  has  nearly  dilated  the  vulva,  and  thej^  go  from  without 
inward.  Often  the  vulva  is  a  little  too  small.  First  the  skin  at  the  posterior  com- 
missure whitens  and  splits,  the  tear  running  down  the  raphe  as  the  head  emerges, 
or  the  skin  and  mucous  membrane  having  been  nicked,  the  posterior  shoulder 
plows  through  the  perineal  bod}'. 

Perineal  tears  are  divided  into  three  classes  or  degrees:  In  the  first  class  an^ 
those  w^here  the  frenulum  or  posterior  commissure  is  torn  to  an  extent  not  exceed- 
ing ^4  inch  toward  the  anus.     The  second  class  includes  all  other  tears  excepting

This  is  a  very  deep  and  extensive  tear,  involving  the  puborecta!  portions  of  the  levator  ani,  exposing  the  rectum 
and  the  sphincter  ani.  The  latter  can  be  seen  lying  at  the  lower  end  of  the  wound,  a  broad  ring  of  pink  muscle.  The 
levator  ends  lie  in  the  deep  recesses  at  the  sides  of  the  rectum.  Notice  how  the  anus  has  dropped  toward  the  coccyx. 
The  sutures  must  lift  it  up  toward  the  pubis.  The  transverse  perineal  muscles  have  pulled  the  walls  of  the  wound  to

those  in  which  the  anus  and  sphincter  ani  are  involved,  these  })eing  designated  as 
of  the  third  degree  or  complete  lacerations  (Fig.  662). 

Fig.  663  shows  a  rare  form  of  perineal  laceration,  and  is  sketched  from  a  case 
observed  by  the  author.  It  is  called  central  rupture  of  the  perineum,  and  is  due 
to  a  high  and  very  resistant  perineum,  narrow  pubic  arch,  or  a  vulva  placed  too  far 
forward.  The  child  is  delivered  through  the  rent,  which  may  be  at  the  side  of  the 
vulvar  orifice  and  anus,  as  in  the  figure,  or  between  anus  and  vulva,  or  the  child 
may  escape  through  the  anus,  tearing  it  in  several  chrections.  The  sphincter  ani 
and  part  of  the  rectovaginal  septum  may  tear  Avithout  extensive  involvement  of 
the  perineum.  In  one  case  the  head  appeared  at  the  vulva  while  an  arm  protruded 
from  the  anus;  in  another — a  breech — one  leg  appeared  through  the  anus.  In  all 
such  cases  it  is  best  to  perform  episiotomy  to  prevent  extensive  destruction  of  the 
tissues.

fascia  over  the  rectum  and  the  deeper  portions  of  the  levator  am 
are  united.  The  needle  passes  deeply  at  the  side  and  bottom  of 
the  wound,  and  verv  superficially  over  the  rectum.  « ith  the 
finger  in  the  bowel  the  retracted  tissues  are  lifted  up  and  per- 
forations avoided.  Too  much  tissue  should  not  be  included  in 
this  tier  of  sutures,  since  the  larcer  part  of  the  levator  am 
muscle  and  fascia  are  to  be  united  by  the  deep  external  stitche.s. 
In  verj'  deep  tears  only  is  this  buried  suture  necessary,  but  it  is 
one  of  the  best  safeguards  against  future  rectocele.

not  to  include  the  underlying  perineum.  Both  sides

THE    PATHOLOGY    OF   LABOR 


Treatment. — Preventive. — Protection  of  tlie  perineum,  according  to  the  rules 
laid  down  in  the  Conduct  of  Labor,  ^^•ill  prevent  a  large  number  of,  but  not  all, 
pelvic  floor  injuries.  Even  episiotomy  does  not  always  suffice  to  overcome  the 
disproportion  between  the  head  and  the  outlet.  (See  p.  305,  Episiotom3^)  Alost

but  a  few  condemn  ejiisiotomy,  asserting  that  a  tear  is  better.  I  believe  that  the 
operation  should  be  often  resorted  to — that  it  will  save  the  lives  of  many  children 
and  often  preserve  the  sphincter  ani  from  injury. 

Slow  delivery  is  the  secret  of  success  in  preventing  tears  in  operations.     The

Floor,  Including  Anterior  Bundles  of  Levator  Ani,  to

Silkworm-gut  or  silver  wire  is  used  for  the  external  sutures. 
By  pulling  out  the  side  walls  of  the  wound  the  needle  can  be  passed 
under  the  retracted  levator  ani  muscles,  and  they  may  thus  be 
brought  together.  The  needle — a  large  one — is  inserted  14  cm. 
from  the  skin-edge,  passes  out  toward  the  tuberosity  of  the  ischium 
under  the  muscle,  deeply  at  the  side,  then  superficially  across  in 
front  of  the  rectum,  and  in  a  reverse  direction  on  the  opposite  side. 
The  point  of  the  needle  describes  a  path  shaped  like  a  long  elUpse, 
not  like  a  circle.  If  a  finger  is  put  in  the  rectum  an  assistant  may 
pull  out  the  tissues.  In  Fig  677  the  suture  numbered  5  is  the 
crown  stitch.  It  is  put  in  last,  passes  through  the  skin  near  the 
fourchet,  then  under  the  tip  of  the  columna  rugarum,  but  not 
through  it,  and  out  on  the  opposite  side.  If  preferred,  a  row  of 
buried  catgut  sutures  may  be  placed,  as  in  this  figure,  to  bring 
the  levator  ani  pillars  together.  Then  the  skin  is  united  with  su- 
perficial sutures.

tendency  to  hurrj^  after  the  for- 
ceps are  applied  is  hard  to  resist, 
and  the  head  is  usuallj'  extracted 
by  forcibly  overcoming  the  resist- 
ance of  the  pelvic  floor.  If  con- 
tinuous auscultation  of  the  heart- 
tones  shows  that  the  fetus  is  in 
good  condition,  the  forceps   ex- 


traction may  be  extended  to  from 
twenty  to  fifty  minutes,  and  in  this  time  the  perineum  can  be  dilated  safely.  To 
counteract  this  desire  to  hurry  it  is  my  custom  to  place  a  clock  in  front  of  the  oper- 
ating table.  Should  threatening  fetal  or  maternal  danger  demand  haste,  a  deep 
episiotomy,  the  colpoperineotomy  of  Dlihrssen,  should  l)e  j^erformed.  Manual  dila- 
tation of  the  perineum  is  also  useful  as  an  operation  preparatory  to  forceps.  In 
several  cases  where  I  had  anticipated  the  necessity  for  rapid  delivery  I  have  used 
the  colpeurj'ntcr  to  dilate  the  vagina  and  levator  ani.  It  is  a  rather  painful  ex- 
pedient, but  the  results  are  good.  When  the  child  is  exceptionally  large,  or  when 
the  head  must  come  through  with  unfavorable  diameters,  or  very  rapidly  (asphyxia 
fcEtalis,  etc.),  deep  episiotomy  is  indicated  (Fig.  6G2).     If,  during  delivery,  spon-

Perineal  tears  seldom  bleed  profusely.  Occasionally  an  artery  recjuires  a

every  tear  of  the  perineum  recjuires  repair,  but  it  may  not  be  advisable  to  do  it 
immediately  after  labor.  If  the  woman  is  collapsed  after  delivery  or  too  exhausted 
for  further  operation;  if  there  is  beginning  infection;  if  the  parts  are  battered  and

Figs.  678  and  679  show  the  technic  of  t\-ing. 
The  middle  fingers  force  the  tissues  together  from 
the  sides,  at  the  same  time  pushing  them  up  toward 
the  pubic  arch  while  the  thread  is  being  drawn.  If 
clots  are  left  in  the  wound,  primarj-  union  may  be 
defeated,  hence  it  is  a  good  plan  to  tie  the  sutures 
while  a  bit  of  gauze  soaks  up  the  blood.  Just  how 
tightly  the  stitches  are  drawn  is  a  matter  of  experi- 
ence. They  should  not  be  pulled  so  tightly  tliat 
they  lie  in  deep  furrows,  because  the  swelling  which 
always  follows  will  cause  them  to  cut  through. 


best  to  postpone  the  operation.  ]My  own 
practice  in  septic  cases  and  those  in  which 
the  parts  are  too  much  torn  to  hope  for  a 
good  result  is  to  put  one  or  two  catgut  su- 
tures in  the  sphincter  ani  and  one  external 
silkgut  stitch  to  support  this  muscle,  and 
leave  the  rest  of  the  Avound  open  for  drainage  and  to  allow  for  eventual  sloughing. 
Several  accoucheurs  take  the  opportunity  of  labor  to  repair  old  lacerations, 
but  my  experience  has  caused  me  to  discontinue  the  practice.  The  dissection 
sometimes  required  is  quite  extensive;  the  levator  ani  is  relaxed,  soft,  and  hard  to 
find;  hemorrhage,  especially  a  general  oozing,  is  very  troublesome;  small  sul)cutane- 
ous  hematomata  from  injury  to  varicose  veins  are  not  uncommon — altogether  it  is 
not  possible  to  do  as  clean  and  tj^Dical  an  operation  as  eight  months  later,  which  I 
consider  the  best  time.  Clean  cases,  too  exhausted  for  immediate  operation,  are  al- 
lowed to  recover  and  are  repaired  A\ithin  twenty-four  hours,  never  later.  I  do  not 
approve  of  early  secondary  perineorrhaphy.     If  the  primary  operation  cannot  be

Hirst  performs  the  secondary  suture  on  the  fifth  or  eigiith  da>',  Ijut  my  experience 
has  been  unsatisfactory.  Capillary  oozing  is  always  troublesome;  the  tissues  are 
brittle  and  stiff;  it  is  almost  impossible  to  work  in  the  connective  tissue  and  to 
lay  bare  the  levator  ani  pillars, — the  crux  of  the  operation, — and  healing  is  not  so 
satisfactory  as  is  desirable. 

Lapthorn  Smith  has  revived  the  old  procedure  of  placing  the  sutures  in  the 
perineum  before  the  head  is  delivered.  Experience  with  this  operation  twenty 
years  ago  caused  me  to  give  it  up. 

It  is  not  advisable  to  place  the  sutures  before  the  placenta  has  been  delivered, 
because:  (1)  The  edges  of  the  wound  cannot  be  properly  coaptated;  (2)  during 
the  passage  of  the  placenta  V)lood  is  forced  into  the  wound;  (3)  the  stitches  may 
tear  out,  and,  further,  should  there  be  a  postpartmii  hemorrhage  requiring  intra-

After  all  the  suture.s  are  tied  the  strands  are  divided  into  bundles, — the  vaginal  in  one  or  two,  the  perineal  in 
one, — and  l^notted  together  smoothly  as  in  the  figure.  By  tying  the  knot  as  shown,  the  ends  will  not  catch  in  the  bed- 
linen  nor  drag  in  the  bed-pan,  and  by  cutting  close  to  the  knot  the  sharp  points  will  be  covered. 

Now  the  gauze  plug  is  removed  from  the  vagina,  the  parts  cleansed,  and  a  pad  applied.  As  the  last  precaution 
the  finger  is  inserted  into  the  rectum  to  make  sure  that  none  of  the  sutiires  has  passed  through  the  bowel.  If  one  has,  it 
must  be  at  once  removed.  After  operative  deliveries  it  is  my  practice  to  catheterize  the  bladder  to  satisfy  myself  that 
it  has  suffered  no  injury. 

uterine  manipulation,  it  may  be  necessary  to  remove  the  sutures  to  allow  the  hand 
to  be  inserted.  Then,  too,  it  takes  the  accoucheur's  attention  away  from  the 
observation  and  conduct  of  the  third  stage  of  labor,  which  may  not  be  done  with 
impunity.  The  parturient  needs  the  undivided  attention  of  the  accoucheur  during 
the  placental  stage. 

Perineorrhaphy. — Anesthesia  is  seldom  necessary,  since,  owing  to  the  stretch- 
ing and  bruising  of  the  parts,  the  tissues  are  not  very  sensitive.  Nervous  patients 
require  ether,  but  sometimes  one  can  operate  with  a  sort  of  half  sleep,  aided  by 
suggestion,  giving  just  enough  ether  to  produce  the  first  stage  of  anesthesia. 
The  patient  should  lie  across  the  bed,  or,  better,  and  to  be  obtained  wherever 
possible,  on  a  properly  prepared  ta])le,  with  th(>  buttocks  hanging  well  over  the 
edge  (Fig.  781).  The  same  instruments  are  needed  as  for  the  gynecologic  perineor- 
rhaphy— needle-holders,  needles,  artery  forceps,  specula,  tissue  forceps,  scissors,

cervix  forceps,  and  uterine  packing  forceps  (Fig.  664).  If  one  has  to  operate  with- 
out trained  assistance,  which  is  the  rule  in  general  practice,  everything — sterile 
sponges,  sterile  towels,  basins  with  antiseptic  solutions,  the  instruments,  etc., 
should  be  arranged  within  easy  reach  of  the  hand.  Abundant  light  is  essential  for 
good  work.  Where  the  laceration  is  complete,  the  accoucheur  should  insist  on 
ha\'ing  sufficient  help,  and  should,  if  necessary,  postpone  the  operation  until  he 
can  get  it.     The  suture  of  a  complete  laceration  of  the  perineum  requires  great

THE   PATHOLOGY    OF   LABOR 


Suturing  a  complete  laceration  will  })e  doscribed  liecause  it  comprises  all  minor  de- 
grees. (The  reader  may  stud>'  all  stej^s  of  the  ojieration  in  detail,  Fios.  666-683.) 
The  after-care  does  not  vary  from  that  usually  pursued  in  pucrperae.  The 
legs  need  not  be  bound  together  unless  the  woman  is  delirious.  When  the  lacer- 
ation has  been  complete,  special  instructions  are  to  be  given  the  nurse  regarding  the 
bowels.  I  do  not  give  opium  to  bind  up  the  bowels,  but  ordt^r  a  semisolid  diet, 
free  from  cellulose,  and  large  quantities  of  water.  On  the  third  day  a  dose  of  castor 
oil  is  given,  and  at  the  same  time  the  nurse  injects,  with  a  soft  rectal  tube,  8  ounces 
of  sterilized  warm  olive  oil  into  the  bowel,  to  be  retained.  The  patient  is  instructed 
not  to  strain  when  the  bowels  are  about  to  move.  If  the  nurse  observes  such  a 
desire  of  the  patient,  she  is  to  insert  the  sterile,  gloved,  and  oiled  finger  into  the

the  constriotor  cunni  and  of  the  urogenital  septum,  then  under  (not  through)  the  vaginal  wall,  and  through  correspond- 
ing structures  on  the  other  side  of  the  wound. 


rectum,  and  gently  break  up  the  fecal  mass  by  pressing  it  against  the  sacrum.  Then 
a  salt  solution  enema  is  given,  and  the  woman  is  instructed  to  hold  it  as  long  as 
possible.  After  the  first  movement  a  daily  laxative  may  be  administered  and  an 
oil  enema  given,  if  possible,  before  each  evacuation.  If  the  accoucheur  has  no 
trustworthy  nurse,  he  should  not  risk  the  success  of  his  operation  in  incompetent 
hands,  but  should  attend  to  the  above  matters  himself.  The  vulvar  pad  should 
be  laid  loosely  against  the  vulva,  so  that  feces  issuing  from  the  anus  may  not  dam 
back  against  the  line  of  sutures. 

The  sutures  are  inspected  daily.  A  small  amount  of  cutting  through  may  be 
neglected,  or  the  spots  touched  with  tincture  of  iodin.  Deeply  cutting  stitches 
had  best  be  removed.  Marked  swc^lling  of  the  vulva  usually  subsides  under  a  warm 
moist  application  of  weak  lead-water  or  acetate  of  aluminum  solution  (sterilized). 


THE    ACCIDENTS    OF   LABOR  739 

The  stitches  are  removed  on  the  tenth  to  the  fourteenth  day,  being  left  longer 
in  the  larger  lacerations.  If  infection  develops,  the  safest  course  is  to  remove 
the  stitches  and  open  up  the  wound  widely  for  drainage.  Occasionally  excessive 
growth  of  granulation  tissue  occurs  at  the  margins  of  the  wounds,  and  after  several 
weeks  the  patient  returns,  complaining  of  pain,  ])urning  in  urination,  and  constant 
irritating  discharge.  Sometimes,  especially  after  forceps  deliveries,  there  is  a 
periostitis  rami  pubis,  which  causes  difficulty  in  locomotion.  The  granulomata 
are  to  be  cauterized  away  with  a  nitrate  of  silver  stick.  Hot  applications  will  help 
heal  the  periostitis. 

LESIONS  OF  THE  VAGINA 

Rarely,  in  spontaneous  labor,  is  the  vagina  torn,  except  in  association  with 
perineal  lacerations,  already  considered. 

Causation. — If  the  vagina  is  congenitally  too  small  (infantile)  or  rigid  (old 
primiparse),  or  scarred  by  disease  (gonorrhea,  etc.)  or  previous  lacerations  or  oper- 
ations, it  may  tear  during  ordinary  labor,  and  certainly  will  give  way  during  arti- 
ficial delivery.  Precipitate  labors  occasionally,  but  forceps  and  rapid  breech 
extractions  particularly,  show  vaginal  tears.  Twisting  the  head  in  the  pelvis  by 
the  forceps — so-called  "rotation" — may  split  the  canal  the  whole  length  and  open 
up  the  perivaginal  spaces  down  to  the  bone.  Hemorrhage  in  such  cases  is  usually 
very  profuse,  may  tax  the  best  skill,  and  may  even  be  fatal.  Tears  of  the  posterior 
vaginal  wall  are  usually  due  to  perforation  by  the  tip  of  the  forceps  blade,  but  may 
be  spontaneous  and  may  even  go  through  into  the  rectum.  Perforating  tears  may 
be  produced  by  friction  of  the  vagina  between  the  head  and  prominent  bony  points, 
as  the  spines  of  the  ischia,  the  promontory  of  the  sacrum,  or  an  exostosis  on  the 
posterior  surface  of  the  pubis,  or  from  stone  in  the  bladder.  The  forceps  also  may 
be  pushed  through  the  vaginal  wall.  Anterior  tears  may  result  from  traumatism 
in  delivery,  from  the  operation  of  hebosteotomy,  when  the  vagina  may  communicate 
with  the  pubic  wound,  and  even  the  bladder  be  torn  open.  During  delivery  after 
craniotomy  sharp  spiculae  of  bone,  if  unprotected,  may  penetrate  the  vaginal  wall, 
or  even  open  up  the  bladder. 

Pressure  necrosis  of  the  vagina  may  occur,  as  was  described  under  Contracted 
Pelvis,  and  if  large  portions  of  the  mucous  membrane  slough  out,  lochiocolpos 
may  result  and  obstruction  from  stenosis  of  the  passage  in  a  subsequent  delivery. 

Description. — Usually  the  tears  are  longitudinal,  and  occupy  the  sulci  along- 
side the  anterior  or  posterior  columna.  In  the  former  case  the  bladder,  in  the 
latter  the  rectum,  is  exposed.  Anterior  lacerations  are  often  accompanied  by  a 
tearing  of  the  levator  ani  pillars  from  their  pubic  attachments.  The  edges  of  the 
tear  are  usually  straight,  except  when  necrosis  occurs,  and  the  connective  tissue  is 
often  widely  opened  up.  In  the  fornices  the  tears  are  generallj^  transverse,  unless 
they  communicate  with  cervix  tears.  Hemorrhage  is  free,  depending  on  the  loca- 
tion. Sometimes  the  tear  extends  more  or  less  circularly  around  the  vagina,  near 
the  cervix,  and  opens  up  the  peritoneal  cavity.  This  is  a  serious  accident,  is  called 
kolporrhexis,  is  closely  akin  to  rupture  of  the  uterus,  and  will  be  considered  together 
with  that  subject. 

Vaginal  tears  may  be  the  port  of  entry  for  infection,  with  paravaginal  abscess 
or  even  general  septicemia,  both  of  which  are  rare  unless  the  case  is  otherwise 
infected.  As  a  rule,  the  lacerations  of  the  upper  third  of  the  vagina  heal  without 
treatment.  Lacerations  of  the  lower  half  of  the  vagina  usuall}'  extend  into  the 
musculature  of  the  pelvic  floor,  and  should  be  treated  as  such,  because,  if  not, 
prolapsus  uteri  will  follow  sooner  or  later.

THE    PATHOLOGY    OF    LABOR 


LESIONS  OF  PELVIC  CONNECTIVE  TISSUE 

Overstretching  of  the  anterior  wall  of  the  vagina,  combined  with  tearing  of 
the  fascia  between  the  bladder  and  the  vagina,  is  responsible  for  the  majority  of 
cases  of  cystocele.  In  many  cases  the  urethra  and  base  of  the  bladder  are  pushed 
down  and  off  from  their  attachments  to  the  posterior  wall  of  the  pubis.  Over- 
stretching of  the  pelvic  connective  tissue,  downward  dislocation  of  the  vagina  and 
its  connective-tissue  supports,  are  causative  of  many  cases  of  procidentia  uteri. 
The  vagina  may  be  actually  torn  away  from  its  pelvic  attachments,  which  occurs 
invariably  when  forceps  are  applied,  or  breech  extraction  made  before  the  cervix 
is  completely  dilated,  and  before  it,  together  with  the  upper  fourth  of  the  vagina, 
is  drawn  up  out  of  the  pelvis.     If  the  accoucheur  wishes  to  verify  this  statement,

let  him  pull  the  head  down  into  the  pelvis  before  the  cervix  has  retracted  and  note 
what  a  large  pad  of  tissue  is  dragged  down  into  the  inlet  before  the  head.  Figs. 
684  and  685  show  the  differences  l)etween  such  a  condition  and  one  where  the  parts 
have  been  drawn  up  into  the  abdomen.  To  a  less  extent  the  same  conditions  are 
present  when  a  woman  bears  down  before  the  cervix  has  retracted  above  the  head. 
The  frequency  of  procidentia  after  forceps  deliveries  and  breech  extractions  before 
complete  dilatation  is  thus  explained.  After  such  destruction  of  the  connective 
tissue  the  fat  disappears  from  the  pelvis,  and  this  should  also  be  consicUn-ed  in  the 
study  of  the  causes  of  prolapse.  Women  who  have  their  first  children  late  in  life 
are  much  more  predisposed  to  procidentia  than  young  primiparse,  because  their 
connective  tissue  is  not  so  elastic,  tearing,  rather  than  stretching. 

Labor  in  elderly  primiparte  is  often,  not  always,  characterized  by  delay  due 
to  rigid  soft  parts.     While  the  dangers  are  exaggerated  in  the  public  mind  I  have

found  that  lacerations  are  more  frequent  and  extensive,  faults  of  mechanism  are 
commoner,  prolonging  labor,  the  infant  mortality  is  higher,  and  the  maternal 
morbidity  also  increased.     (See  Spain  for  literature.)

742  THE    PATHOLOGY    OF    LABOR 

Prognosis. — Perineal  and  vaginal  lacerations  are  not  serious  if  properly  treated. 
Infection  is  the  worst  danger.  Heniorrliage  may  be  fatal  if  large  veins  or  arteries 
are  involved.  In  placenta  pra^via  cervicovaginal  tears  are  often  fatal.  Scar  for- 
mation may  later  deform  and  displace  the  vagina  and  neighboring  hollow  organs. 
Incontinence  of  urine  maj^  be  thus  produced  from  scars  pulling  open  the  neck  of 
the  bladder,  also  strictura  recti.  The  uterus  may  be  dislocated  in  all  directions. 
In  one  case  I  saw  the  cervix  pulled  down  to  the  introitus.  Subsequent  labors  may

Fig.  687. — Repair  of  Laceration-  at  Base  and  Side  of  Bladder. 
A  broad,  short  speculum  retracts  the  perineum,  a  pad  holds  the  cervix  out  of  the  way  and  absorbs  the  excess 
blood,  a  narrow  speculum  lifts  up  the  bladder.  Thus  exposed,  the  wound  is  visible,  but  not  comfortably  accessible. 
The  needle  passes  through  the  posterior  lip  of  the  wound  first,  then  across  the  base  of  the  bladder,  avoiding  the  ureters, 
and  out  through  the  upper  Up  of  the  wound,  the  point  striking  the  speculum  and  sliding  over  it  into  the  bite  of  the 
assistant's  arterv  forceps.  If  it  is  possible  to  pick  up  the  torn  levator  ani  pillar  at  X  and  attach  it  to  the  periosteum 
or  obturator  fascia  at  F,  it  should  be  attempted.  There  are  large  veins  at  this  point.  Occasionally  it  may  be  easier 
to  engage  the  structures  in  the  needle  by  reversing  the  process  as  shown  in  the  drawing. 

or  those  which  are  to  be  exposed  to  injury  from  rapid  stretching,  many  tears  may 
be  avoided.  If  the  laceration  of  the  anterior  and  lateral  walls  of  the  vagina  is 
unavoidable  and  the  levator  ani  is  endangered,  it  is  better  to  make  a  deep  incision 
into  this  muscle  in  its  median  portion,  than  to  allow  it  to  be  pulled  off  the 
ramus  pubis.  Tears  in  the  upp(n-  third  of  the  vagina  recjuire  no  treatment  unless 
they  bleed.  A  few  stitches  usually  will  stop  the  heniorrliage,  but  sometimes  the 
flow  is  so  profuse  that  one  cannot  see  the  wound.  Here  uterovaginal  tamponade  is 
indicated  instead  of  the  suture.  Next  day  an  attempt  at  repair  may  be  made,  or  the 
operation  postponed  for  six  months.  If  free  bleeding  obstructs  the  view,  rendering 
the  operation  technically  difficult,  it  may  be  possible  to  tampon  that  part  of  the 


THE    ACCIDENTS    OF   LABOR  743 

wound  from  which  the  hemorrhage  comes  while  the  other  part  is  being  sutured,  or  the 
suture  may  be  passed  entirely  under  the  guidance  of  the  finger.  After  suturing,  it  is 
best  to  do  a  uterovaginal  tamponade  to  prevent  hematoma  formation  in  tlie  loose 
paravaginal  tissues.  Tears  around  the  base  of  the  bladder  require  accurate  repair 
— even  then  cystocele  may  not  always  be  prevented.  If  the  puborectal  portions  of 
the  levator  ani  are  torn  from  the  posterior  surface  of  the  pubis,  this  fact  may  be 
discovered  by  opening  up  the  rent  widely  to  view.  I  have  tried  to  reunite  the 
muscle  to  the  obturator  fascia,  having  failed  to  attach  it  to  the  bone,  and  with  fair 
success.  A  broad  speculum,  very  good  light,  sharply  curved  needles,  and  several 
assistants  are  needed  for  good  repair  work  in  the  vagina. 


HEMATOMA  VULV^  ET  VAGINA 

Blood-vessels,  particularly  the  veins,  in  the  pelvis  may  burst  during  pregnancy, 
labor,  or  postpartum,  and  a  blood  tumor  or  "thrombus  "  form  in  the  loose  connective 
tissue.  Hematomata  have  been  found  under  the  skin  of  the  vulva,  around  the 
vagina,  under  the  broad  ligaments,  in  the  broad  ligaments,  and  they  show  a  tendency 
to  enlarge,  following  the  lines  of  cleavage  of  the  connective-tissue  layers  or  fasciae. 
If  below  the  deep  pelvic  fascia,  they  distend  the  perineum  and  dislocate  the  rectum 
and  anus,  forming  tumors  sometimes  as  large  as  a  cocoanut.  If  around  the  vagina, 
they  may  fill  up  the  pelvis,  forcing  the  vagina  to  the  side  and  closing  it,  causing 
obstruction  to  delivery  or  to  the  flow  of  the  lochia.  They  may  be  pedunculated  in 
the  vagina,  and  may  occur  in  a  septum  vaginae.  If  at  the  base  of  the  broad  liga- 
ments, they  may  extend  up  into  the  false  pelvis  under  Poupart's  ligament,  or, 
behind,  they  may  dissect  up  to  the  kidney  back  of  the  peritoneum.  In  the  case 
from  which  Fig.  688  was  taken  the  blood  tumor  was  so  extensive  that  the  woman 
nearly  died  of  anemia — the  vagina  was  closed,  the  vulva  displaced  downward,  and 
the  cavity  formed  by  the  blood  extended  up  out  of  the  pelvis  to  a  level  with  the 
anterior  superior  spine  of  the  ilium.  While  the  hematoma  begins  to  form  at  once, 
it  requires  a  few  hours  for  its  presence  to  become  manifest,  and  usually  within  ten 
hours  the  blood  mass  is  fully  developed. 

Etiology. — The  bursting  of  the  vessel  may  be  caused  by  injury — the  trauma- 
tism of  spontaneous  labor— or  by  the  forceps,  etc.  Pressure  necrosis  explains  the 
cases  of  formation  of  hematoma  late  in  the  puerperium — on  the  third,  eleventh,  and 
twenty-first  days,  as  reported.     Varices  are  said  not  to  favor  hematomata. 

Rough  uterine  massage  in  the  treatment  of  postpartum  hemorrhage  ma}'  cause 
small  hematomata  in  the  subperitoneal  connective  tissue  and  in  the  broad  liga- 
ments, but  perhaps  in  the  fatal  cases,  where  such  findings  were  made,  the  woman 
died  of  a  hemophilic  diathesis  and  the  latter  caused  the  blood  extravasations.  In 
one  of  my  cases,  during  the  treatment  of  placenta  praevia,  a  tumor  developed  in  the 
perivaginal  connective  tissue,  extending  from  the  vulva  to  the  uterus,  which  was 
taken  to  be  a  hematoma,  but  upon  cutting  into  it  with  the  expectation  of  turning 
out  a  clot,  none  was  found,  the  tissues  being  simph'  infiltrated  with  blood.  Hema- 
tomata are  rare,  about  1  to  4000  labors,  but  statistics  vary.  In  an  experience 
comprising  the  pathologic  work  of  over  20,000  routine  cases,  only  five  cases  of  large 
hematomata  have  come  under  my  notice.  Small  hematomata  are  not  exceedingly 
rare,  and  their  formation  may  sometimes  be  observed  Avhen  a  vein  is  pricked  while 
repairing  the  torn  perineum. 

Symptoms. — Intense  pain  is  the  most  prominent  symptom,  and  the  intelligent 
patient  will  describe  the  tearing  open  of  the  tissues  and  the  intolerable  pressure  on  the 
rectum  and  bladder.  Sometimes  the  skin  or  the  vagina  covering  the  tumor  bursts, 
and  the  patient  may  bleed  to  death.  If  the  hematoma  burrows  a  great  distance, 
signs  of  anemia  from  internal  hemorrhage  appear.  Small  extravasations,  as  a  rule, 
are  quickly  absorbed.     Larger  ones  usually  become  infected,  with  abscess  forma- 


744 


THE    PATHOLOGY    OF    LABOR 


tion.  or  even  general  septicemia,  but  sometimes  they  open  spontaneously,  the  clots 
are  discharged,  and  the  cavity  closes  (rare).  Hematomata  which  complicate  rup- 
ture of  the  uterus  are  not  considered  here. 

Prognosis. — Nowadays  death  from  this  accident  is  rare,  but  formerly  the  mor- 
tality was  from  12  to  40  per  cent.  If  the  tumor  does  not  become  infected,  recovery 
is  the  rule.  If  it  extends  up  under  the  peritoneum  and  infection  of  the  immense 
blood-masses  takes  place,  peritonitis  is  the  usual  outcome.  It  is  wise  to  make  a 
guarded  prognosis  until  it  is  determined  how  far  the  hematoma  is  going  to  burrow, 
and  whether  or  not  infection  will  occur. 

Treatment. — If  the  hematoma  l^egins  to  form  during  labor,  its  course  must  at 
first  be.  carefully  watched,  and  if  its  growth  is  rapid,  it  is  to  be  incised  and  packed.

In  cases  where  delivery  of  the  child  may  be  accomplished  this  should  be  effected, 
and  then  the  whole  uterovaginal  canal  firmly  tamponed,  together  with  the  hematoma 
sac.  If  the  tumor  begins  to  form  before  the  placenta  is  delivered,  the  latter  is 
manually  removed,  and  then  the  tamponade  made,  as  in  the  last  instance.  If  the 
hematoma  is  found  after  labor,  at  first  expectancy  and  ice  applications  are  to  be 
practised,  but  if  the  hemorrhage  into  the  tissues  continues,  shown  by  increasing 
size  of  the  tumor  and  redoul^led  pain  cries  of  the  woman,  the  sac  must  be  broadly 
opened,  the  clots  and  fluid  blood  turned  out,  bleeding  vessels,  if  found,  ligated,  and 
every  crevice  of  the  cavity  firmly  packed  with  sterile  or  mildly  antiseptic  (not 
styptic)  gauze.  Then  the  uterovaginal  canal  is  packed  and  a  firm  abdominal  binder 
applied.     To  procure  a  bloodless  field  while  operating  the  Momburg  belt  or  an

aorta  compressor  may  be  used,  this  only  in  critical  cases.  If  it  is  possible  to  wait 
twenty-four  to  forty-eight  hours  before  performing  this  operation  to  allow  firm 
thrombosis  in  the  torn  vessels,  the  possibility  of  secondary  hemorrhage  at  the  opera- 
tion is  avoided.  Small  hematomata  may  be  left  to  be  absorbed,  but  all  are  to  be 
opened  at  the  first  sign  of  infection. 

LESIONS  OF  THE  CERVIX 

Every  labor  is  attended  by  more  or  less  injury  to  the  cervix,  since  even  a  normal 
uterus  cannot  stand  the  enormous  radial  dilatation  reciuired  for  the  passage  of  the 
child.  Large  tears  of  the  cervix  result  from — (1)  Too  rapid  or  too  forceful  dilata- 
tion by  the  powers  of  labor  (precipitate  births)  or  by  the  accoucheur,  with  his 
operative  deliveries  before  the  os  is  completely  dilated;  (2)  from  disease  of  the  cervix, 
anatomic  rigidity,  old  primiparity,  healed  ulcers  and  scars  from  former  deliveries 
or  operations,  cancer,  syphilitic  and  gonorrheal  induration,  etc.;  (3)  too  large  child 
or  congenital  smallness  of  the  cervix.  Most  of  the  tears  are  of  the  first  class  and 
are  due  to  violence.  Every  case  of  accouchement  force  and  every  manual  or  instru- 
mental dilatation  of  the  cervix  is  attended  by  more  or  less  numerous  and  deep  lacer- 
ations. If  the  operation  is  performed  before  the  cervix  is  completely  effaced,  serious 
or  even  fatal  injuries  may  result. 

The  lesion  may  be  a  small  nick  in  the  mucosa,  or  a  deep  rent  extending  through 
the  cervix,  the  vaginal  vault,  the  parametrium,  even  to  the  brim  of  the  pelvis, 
and  up  under  the  peritoneum  of  the  broad  ligaments,  or  even  into  the  peritoneal 
cavity- — with  all  grades  between.  The  large  rents  are  treated  under  the  subject  of 
Rupture  of  the  Uterus.  Lateral  or  bilateral  lacerations  are  most  commonly  found, 
but  radial  tears,  from  one  to  five  in  number,  may  be  observed,  and  they  occupy  any 
part  of  the  cervix.  Sometimes  a  portion  of  the  cervix  is  dragged  off  the  uterine 
body  at  the  vagino-uterine  junction,  or  the  whole  cervix  may  thus  be  amputated 
and  cast  off  as  a  ring  of  tissue.  The  circular  amputation  of  the  cervix  may  be  pro- 
duced by  trjdng  to  drag  a  colpeurynter  through  the  unprepared  cervix,  or  the 
uterus  may  force  the  head  down,  carrying  the  cervix  before  it.  The  resulting  scar 
nearly  always  closes  the  uterus.  The  anterior  lip  of  the  cervix  may  be  caught 
between  the  head  and  the  pubis  and  be  squeezed  off,  or  suffer  so  much  compression 
that  it  becomes  necrotic. 

Cervix  tears  are  usually  not  discovered  until  after  the  child  is  delivered,  when 
the  hemorrhage  begins.  Bleeding  is  not  constant.  Unless  a  large  branch  of  the 
uterine  artery  or  a  vein  is  torn  across,  there  is  none  of  any  moment.  In  placenta 
pra3via  cervix  tears  usually  bleed  furiously,  the  immensely  dilated  veins  being 
opened  l)y  even  a  superficial  lesion. 

Prognosis. — Small  tears  of  the  cervix,  unless  infected,  heal  without  trouble, 
but  larger  tears  always  leave  deforming  scars,  leading  to  ectropion,  catarrh,  and, 
some  say,  to  carcinoma.  Perforating  tears  are  often  fatal.  Chronic  metritis 
undoubtedly  follows  large  cervix  tears,  and,  since  they  are  always  associated  with 
injury  of  the  pelvic  connective  tissue,  descensus  uteri  often  results. 

Treatment. — In  spontaneous  deliveries  it  is  not  advisable  to  pass  the  finger 
into  the  uterus  in  search  of  injuries  unless  bleeding  or  other  indication  (for  example, 
collapse,  precipitate  birth)  demands  it.  IVIany  advocate  the  search  for  and  the 
immediate  repair  of  all  lesions  as  a  routine.  In  hospitals  with  good  technic  such  a 
course  might  be  followed,  but  in  the  home  it  is  generally  impracticable.  After 
forceps  and  other  operative  deliveries,  and  always  when  injury  is  suspected,  a 
complete  digital,  and,  if  need  be,  a  specular,  examination  is  to  be  made.  Whether 
or  not  to  sew  up  the  tear  in  such  cases  depends  on  circumstances.  Where  infection 
is  present  or  probable,  the  tear  is  not  sutured  unless  it  bleeds  and  packing  will  not 
stop  it.  If  the  operator  has  good  help,  the  lacerations  are  repaired  in  all  clean 
operative  cases,  whether  or  not  there  is  bleeding.     Under  unfavorable  operating-

room  conditions  the  woman  is  safer  with  the  eei-\ix  open  to  (h-ain,  and  repair  may- 
be made  later.  Hirst  and  a  few  others  recommend  secondary  suture  on  the  fifth 
or  sixth  day  of  the  puerperium,  but  tiie  author  does  not  advise  it,  for  reasons  already 
given  under  Perineorrhaphy. 

Fig.  689  shows  a  typical  cervical  laceration  extending  to  the  fornix  vaginae,

the  result  of  a  forceps  delivery  through  a  narrow  os.  It  was  bleeding  moderately 
and  was  easily  sewed,  as  shown.  By  means  of  the  vulsellum  forceps  or  the  cervix 
forceps  shown  in  Fig.  690  the  two  lips  of  the  uterus  are  drawn  down  to  the  vulva 
and  become  readily  accessible  for  suture.     (See  Postpartum  Hemorrhage.) 

When  bleeding  is  profuse,  it  is  not  so  easy  to  sew  the  cervix,  because  it  is 


THE    ACCIDENTS    OF   LABOR  747 

hidden  in  a  pool  of  ))lood.  A  bullet  forceps  may  be  clamped  on  the  base  of  the 
broad  ligament,  as  adviscxl  by  Henkel  for  tcmporar}'  hemostasis.  Another  plan  is 
to  pass  the  needle  from  the  inside  of  th(!  cervix  untler  the  guidance  of  the  finger, 
and  tie  the  suture  inside  the  uterus.  The  balance  of  the  stitches  are  put  in  from 
the  outside  of  the  cervix,  the  most  important  being  the  uppermost  one,  near  the 
fornix  vagina?,  since  it  is  intended  to  stop  the  hemorrhage  which  comes  from  the  large 
vessels  here.  Continued  suture  is  used  if  haste  is  demanded,  otherwise  interrupted 
No.  2  hardened  catgut.  Since  the  ureter  is  close  by,  the  needle  in  the  first  suture 
must  be  passed  in  a  direction  nearly  parallel  to  the  uterine  body.  The  others  are 
transverse  and  pass  to,  but  not  through,  the  mucosa.  They  may  be  draAvn  fairly 
tight,  because  the  cervix  rapidly  shrinks  postpartum.  The  ]\Iomburg  belt  has 
been  used  in  urgent  cases  to  stop  the  Ijleeding  until  the  wound  could  be  sutured. 
Should  infection  begin  in  the  puerperium,  the  stitches  are  to  be  at  once  removed 
and  drainage  provided,  because  otherwise  the  parametria  will  be  rapidly  involved, 
and  even  fatal  septicemia  result.     Douches  are  contraindicated. 


RUPTURA  UTERI 

This  fearful  accident  occurs  oftener  than  is  generally  ])elieved,  and  few  emer- 
gencies in  all  medicine  require  so  much  of  what  makes  a  great  surgeon  as  does  this 
one.  The  uterus  may  rupture  during  pregnancy  and  during  labor,  and  since  the 
latter  is  more  common,  it  will  be  first  considered. 

During  Labor. — Etiology. — Ruptures  of  the  uterus  are  divided  into  two  classes 
— spontaneous  and  violent  or  traumatic.  Spontaneous  ruptures  are  those  which 
occur  as  the  result  of  the  natural  forces  of  labor,  or  because  the  muscle  of  the  uterus 
is  pathologically  altered,  so  that  it  bursts  from  the  ordinary  processes  of  labor  or 
gestation.  Violent  or  traumatic  ruptures  are  those  which  result  from  injury,  either 
from  the  hand  or  instrument  of  the  attendant  or  by  external  agencies.  Often  the 
uterine  muscle  is  so  thinned  by  the  action  of  labor  that  it  l)ursts  wdth  only  a  little 
traumatism.  The  causes  of  actual  rupture  may  be  divided  into  predisposing  and 
exciting.  Predisposing  causes  are,  first,  those  conditions  which  produce  a  weaken- 
ing of  the  uterine  wall,  as  fatty  or  hyaline  degeneration  of  the  muscle;  pressure 
necrosis  during  prolonged  labor;  scars  from  previous  operations  (cesarean  section, 
salpingectomy  with  excision  of  uterine  cornu,  curetage) ;  scars  from  previous  rup- 
ture, from  puerperal  septic  processes,  and  old  inflammations;  thinned  spots  from 
the  removal  of  adherent  placenta  in  previous  labors;  fibroids  and  other  neoplasms; 
adherent  uterus;  overdistention  of  part  of  uterus;  congenitally  undeveloped  uterus; 
pregnancy  in  a  horn;  interstitial  pregnane}"  gro^vth  of  the  placenta  into  the 
uterine  musculature;  placenta  praevia;  edema  of  the  lower  uterine  segment  the 
result  of  prolonged  labor ;  polyhydramnion.  The  second  group  of  predisposing  causes 
comprises  all  the  mechanical  factors  which  stop  the  advance  of  the  child  through 
the  birth-canal,  as  contracted  pelvis  of  all  kinds;  overgrown  fetus;  deformities  of  the 
child  which  increase  its  size,  especially  hydrocephalus;  malpresentations  (shoulder, 
face,  and  brow,  anterior  and  posterior  parietal  bone);  malpositions,  as  occipito- 
posteriors;  delayed  rotation  of  the  head;  obstruction  of  the  soft  parts,  as  tumors 
blocking  the  pelvis,  atresia  cervicis  or  vaginie,  rigid  perineum;  and  incarceration 
of  the  cervix  between  the  presenting  part  and  the  pelvic  brim.  Pendulous  abdo- 
men, by  putting  the  posterior  uterovaginal  wall  on  the  stretch,  creates  a  condition 
favorable  to  rupture,  the  resulting  lesion  l)eing  called  kolpoporrhexis,  or  kolpor- 
rhexis.  Unless  the  natural  powers  can  overcome  these  obstructions  bj^  a  moderate 
amount  of  effort,  something  has  to  give  way,  and  the  weakest  point  or  the  most 
overstretched  point  is  the  site  of  rupture. 

Exciting  causes  of  the  rupture  are  the  contractions  of  the  uterus  and  mechanical 
insult  or  violence.     To  understand  the  mechanism  of  spontaneous  rupture  it  is 


748 


THE    PATHOLOGY   OF   LABOR 


necessary  to  refer  to  the  normal  mechanism  of  labor  and  the  formation  of  the  par- 
turient canal.  We  are  intlel)ted  to  ]\Iichaelis,  Bandl,  and  Freund  for  the  foundation 
of  our  knowledge  of  this  subject.  Throughout  labor  the  fundus  of  the  uterus  con- 
tracts, while  the  isthmus  and  cervix  are  dilated  from  above  do^^^lward,  the  muscle 
being  differentiated  into  an  upper  zone  of  contracting,  and  a  lower  of  dilating, 
fibers.  The  fibers  of  the  isthmus  uteri  and  cervix  are  drawn  upward  into  the  body 
of  the  uterus,  and,  at  the  junction  of  the  contractile  with  the  dilating  portions,  is  a 
well-defined  ring  of  muscle  which  Bandl  called  the  contraction  ring.  The  sacro- 
uterine ligaments  fix  the  cervix  in  the  pelvis  behind,  the  bases  of  the  broad  ligaments 
fix  it  at  the  sides,  and  the  connective  tissue  at  the  base  of  the  bladder  anchors  it  in

Arrows  indicate  direction  of  tension. 

front,  all  of  which  connective  tissue  and  partly  nmscular  support  prevent  too  great 
upward  retraction  of  the  cervix.  An  additional  and  important  factor  in  the  mechan- 
ism of  rupture  is  the  fixation  of  the  cervix  by  the  head,  squeezing  it  against  the  bony 
pelvis.  This  is  particularly  likely  to  happen  if  the  bag  of  waters  ruptures  before  the 
cervix  is  dilated  and  retracted  above  the  presenting  part.  The  fundus  uteri  is 
held  down  and  prevented  from  pulling  too  far  up  over  the  child,  and  away  from  the 
pelvis,  by  the  guy-rope-like  action  of  the  round  ligaments  (P^ig.  169)  and  the  pres- 
sure of  the  abdominal  wall.  It  is  easy  to  see  that  if  the  child  may  not  advance 
along  the  birth-canal,  the  continued  action  of  the  uterus  will  result  in  the  contractile 
portion  having  forced  nearly  the  whole  child  down  into  the  dilating  portions,  the 
lower  uterine  segment  and  cervix,  and  itself  having  retracted  above  the  child  as 


THE    ACCIDENTS    OF    LABOR

far  as  the  round  ligaments  and  the  alxlominal  wall  would  permit.  Its  wall  may- 
have  a  thickness  of  onl}^  a  few  millimeters,  while  the  fundus  is  4  cm.  thick.  Fig. 
691  shows  the  condition.  Sometimes  the  cervix  is  more  or  less  fixed  at  the  inlet 
and  cannot  wholly  retract  with  the  lower  uterine  segment,  and,  therefore,  the 
latter  is  drawTi  out  in  the  length  and  may  tear  transversely  (Fig.  692).  Since  the 
dilatation  of  the  lower  uterine  segment  is  never  symmetric,  owing  to  the  obliquity 
of  the  uterus,  the  irregularity  of  the  body  contained  therein,  pendulous  abdomen, 
etc.,  some  portion  of  it  is  stretched  more  than  the  rest,  and  here  the  rupture  occurs. 
As  a  rule,  first  the  muscle-fibers  separate  and  tear,  then  the  mucous  membrane 
gives  way,  and  finally  the  peritoneal  covering  of  the  uterus.  I  have  on  several 
occasions  felt  this  occurrence  under  my  hand.  If  the  cervix  has  alread}'  been 
dilated  and  fully  taken  up  to  form  part  of  the  parturient  canal,  it  cannot  be  fixed 
below,  but  retracts  upward,  with  the  lower  uterine  segment,  and  the  full  force  of 
this  retraction  is  distributed  along  the  wall  of  the  parturient  canal  from  the  contrac-

tion  ring  down  the  vagina  to  the  attachments  of  the  latter  onto  the  pelvic  floor. 
If  the  stretching  of  this  canal  is  too  great,  the  rupture  will  occur  at  its  weakest  spot, 
and  this  is  usually  the  posterior  fornix  of  the  vagina.  Indeed,  in  cases  of  shoulder 
presentation,  immense  hydrocephalus,  pendulous  abdomen,  where  the  presenting 
part  cannot  imprison  the  cervix  against  the  pelvis,  we  find  such  ruptures  of  the 
vagina  or  kolpoporrhexis  (Hugenberger)  (Fig.  693). 

Ruptures  in  the  lower  uterine  segment  are  usuallj'  longitudinal  or  oblique; 
those  in  the  fornix  vaginae,  usually  transverse  or  even  completely  circular. 

Violent  or  traumatic  ruptures  have  no  special  mechanism,  but,  as  a  rule,  the 
fundus  is  already  dra^^^l  up,  and  the  lower  segment  and  vagina  thinned  out  as 
above  described  at  the  time  the  causative  injury  is  inflicted,  and  on  this  account 
the  shape  and  location  of  the  tear  are  very  similar  to  the  spontaneous  ones.  The 
forceps  blade  or  the  cranioclast  may  be  pushed  through  the  wall,  or  grasp  a  portion 
of  the  musculature  and  crush  it.     Traction  with  the  forceps  pulls  the  cervix  down,

THE    PATHOLOGY    OF    LABOR 


and  a  transverse  split  occurs  in  the  lower  uterine  segment,  already  stretched  in  the 
length  to  the  point  of  bursting.  The  hand  introduced  alongside  the  child  contained 
in  the  ad  maxima  distended,  lower  segment  may  cause  tiie  tear;  or  the  attempt  to 
turn  the  child  by  bringing  the  trunk  down  into  the  pelvis  alongside  the  head  puts 
too  great  a  strain  on  this  portion  of  the  uterus;  or  the  hand  pushes  the  uterus  up 
away  from  the  vagina,  and  the  rupture  occurs  at  the  junction  of  the  latter  with  the 
cervix,  or  finally  too  rapid  delivery  through  an  unprepared  cervix  simply  l)ursts  the 
narrow  canal.  Instrumental  injuries  usually  are  found  in  the  neighborhood  of 
the  fornix  vaginae  and  the  cervix;  the  others  usually  in  the  overdist ended  lower 
uterine  segment,  and  it  is  evident  that  the  operator  only  completed  a  tear  that 
was  already  being  prepared  for  or  just  beginning. 

Frequency. — Freund,   from  the  collected   reports  of   17   authors,   found   one 
rupture  to  2114  cases,  but  the  individual  reports  varied  from  1  to  234  to  1  to  6100

cases.  These  statistics,  witli  few  exceptions,  came  from  hospitals,  and  since  the 
rupture  cases  go  to  the  hospitals,  the  figures  are  large. 

Multiparse  are  oftener  thus  injured  than  primiparse, — about  eight  times  as 
often, — and  the  danger  increases  with  the  number  of  children.  This  is  due  to  the 
structural  changes,  the  weakness  of  the  muscular  fil)ers,  the  scars  and  inflamma- 
tions, the  residues  from  previous  labors.  In  primiparse  the  perforating  cervix 
tears  are  commoner  than  the  true  uterine  ruptures.  The  years  of  greatest  fre- 
quency are  from  thirty  to  forty.  Women  wnth  loose  abdominal  walls  are  more 
endangered,  and  fat  women  seem  to  be  especially  predisposed. 

Pathology. — Ruptures  are  divided  into  two  classes — the  complete,  where  the 
peritoneal  cavit}-  is  opened,  and  the  incomplete,  where  the  nmscle  is  torn,  but  the 
peritoneum  remains  intact. 

Fig.  694  shows  an  incomplete  rupture  with  a  suliperitoneal  hematoma,  and

into  the  peritoneal  cavity  had  ensued.     Note  how  the  peritoneum  has  been  stripped

off  the  uterus.  In  violent  or  traumatic  ruptures  the  cervix  is  oftenest  split  in  the 
length,  or  at  least  the  rupture  is  usually  longitudinal;  in  spontaneous  ruptures  the 
tear  is  usually  more  or  less  oblique  and  often  transverse,  while  it  may  be  L  or  V 
shaped.  The  anterior  uterine  wall  is  oftenest  involved,  then  the  sides,  the  left 
more  commonly,  and  least  frequently  the  posterior  wall.  Double  tears,  one  on 
either  side  of  the  uterus,  are  on  record.  Rupture  of  the  vagina — kolpoporrhexis — 
is  rare,  and  oftenest  the  posterior  fornix  is  torn,  while  the  anterior  and  lateral  walls 
suffer  less.  According  to  Stschotkin,  there  were  36  posterior,  24  anterior,  8  lateral, 
and  8  completely  circular  tears  in  74  cases.  Involvement  of  the  bladder  is  a  very 
serious  complication,  with  87  per  cent,  mortality  (Klien),  but  is,  fortunately,  rare. 
The  edges  of  the  tear  arc  suggillated  and  ragged.  If  the  broad  ligaments  are 
opened  up,  the  veins  and  arteries  can  be  felt  traversing  the  connective-tissue  spaces, 
which  are  filled  with  blood,  and  sometimes  with  air  or  gases  of  decomposition 
(emphysema).  The  hemorrhage  comes  from  the  large  venous  plexuses,  from  the 
utenne  arteries  and  its  large  branches,  especially  the  uterovaginal.     The  hematoma

may  burrow  in  the  connective  tissue,  far  away  from  the  site  of  rupture,  even  to 
the  kidneys.  If  the  tear  is  behind  the  broad  ligaments,  the  bleeding  may  be  small, 
but  if  it  is  through  the  bases  of  the  broad  ligaments  or  involvesthe  siteof  the  placenta, 
the  woman  may  die  in  a  few  minutes  from  the  sudden  immense  loss  of  blood.  In 
my  cases  the  loss  of  blood  Avas  greatest  in  the  incomplete  ruptures,  while  the  shock 
was  most  evident  with  the  complete  ones.  Urine,  meconium,  lanugo,  vernix 
caseosa,  and  liquor  amnii  may  be  found  in  the  peritoneal  cavity. 

Usually,  at  the  height  of  a  pain,  the  thinned  portion  of  the  uterus  gives  way, 
but  sometimes  the  separation  of  the  fibers  is  gradual,  and  the  rupture  is  completed 
without  producing  alarming  symptoms  (latent  rupture).  Only  after  peritonitis 
sets  in  is  the  condition  recognized,  or,  indeed,  at  a  subsequent  labor,  when  the 
uterus  ruptures  again  at  the  site  of  the  previous  scar.  The  point  which  is  most 
subjected  to  the  strain  gives  way;  then  the  uterine  contractions  force  the  child 
through  the  weak  spot  thus  created.  After  the  child  is  expelled  through  this  new 
passage  the  uterus  contracts  down  beside  it  and  comes  to  rest.     Sometimes  the

rent  is  enlarged  by  the  operative  delivery.     Intestines  and  omentum  may  protrude 
through  the  opening  into  the  vagina. 

Incomplete  ruptures  occur  under  the  same  circumstances,  and  from  the  same 
causes,  as  the  perforating  ones,  and  the  tear  may  involve  one  or  two  of  the  layers 
of  the  uterus.  That  is,  the  peritoneum  only  ma}'  split,  and  may  give  rise  to  intra- 
peritoneal hemorrhage,  mild  or  fatal,  or  the  muscle  only  may  part,  the  mucous 
membrane  and  peritoneum  being  intact,  or  the  peritoneum  and  muscle  break, 
leaving  the  mucosa,  or  the  mucous  membrane  and  muscle  part,  leaving  the  serous 
membrane,  the  last  being  the  commonest  variety.  Hematoma  is  the  rule  in  such 
cases,  and  the  tear  is  always  located  at  a  spot  where  the  peritoneum  is  loosely 
attached  to  the  uterus,  the  sides,  and  near  the  bladder.  Cervix  tears,  if  extensive, 
are  usually  of  this  t}npe.  Bursting  of  a  varix  in  or  on  the  broad  ligament,  with  sub- 
peritoneal or  intraperitoneal  hemorrhage,  tearing  of  an  artery  in  the  broad  liga-

ment,  have  been  observed  as  rare  causes  of  death.  Possibl}'  some  such  accidents 
occur,  but  are  not  discovered. 

Symptoms. — If  the  accoucheur  is  on  the  alert,  he  will  almost  always  be  able 
to  detect  a  threatening  rupture  of  the  uterus,  and  diagnose  early  a  dangerous 
thinning  of  the  lower  uterine  segment.  In  contracted  pelves  and  all  cases  of 
mechanical  obstruction,  and  where  he  knows  that  the  uterine  wall  is  weakened,  the 
attendant  will  be  especially  watchful.  It  must  be  said,  however,  that  sometimes 
the  tear  will  occur  so  gradually  that  the  symptoms  will  hardly  attract  notice,  or  the 
tissues  wall  suddenly  give  way  without  any  apparent  cause  and  without  any  warn- 
ing. This  may  occur  in  the  beginning  of  laljor,  wdth  few  pains  and  intact  membranes, 
or  even  during  pregnancy,  but  it  is  very  exceptional. 

Fortunately,  symptoms  are  usually  present.  The  parturient  is  restless,  toss- 
ing and  rolling  about  the  bed;  she  is  anxious  about  tlie  labor,  because  there  is  no 
progress  in  spite  of  her  strong  pains;   slie  complains  of  constant  soreness  and  almost

continual  pain  over  the  hj-pogastrium,  and  unconsciously  her  hands  support  the 
lower  uterine  segment  with  every  uterine  contraction;  the  face  is  reddened,  but 
the  alae  nasi  are  gray;  the  mouth  and  tongue  are  drj'  and  red;  she  complains  of  a 
desire  to  urinate  frecjuently,  and  bears  do^^'n  with  the  pain  in  a  helpless  sort  of  way, 
and  begs  for  relief  incessantly;  the  temperature  is  slightly  raised;  the  respiration 
is  panting ;  the  pulse  is  fast  and  usually  of  high  tension.  If  the  woman  has  sjTicopal 
attacks,  one  can  infer  that  slight  tearing  of  the  uterus  has  begun. 

The  Rupture. — Suddenh',  during  the  acme  of  a  pain,  or  while  the  woman  is 
tossing  from  one  side  to  the  other,  she  complains  of  a  sharp,  tearing  pain  in  the 
lower  belly,  and  may  exclaim  that  something  has  burst  within  her.  Now  the 
picture  rapidly  changes  from  sthenic  to  asthenic.  As  a  result  of  the  shock  and 
internal  hemorrhage  the  face  pales,  the  lips  whiten  or  become  cyanotic,  the  features 
sink  in,  cold  sweat  appears  on  the  nose  and  forehead,  the  temperature  drops,  the 
pulse  becomes  small  and  running,  even  filiform,  and  the  respiration  sighing;    the

pains  cease  and  the  patient  is  ominously  quiet  for  a  short  while.  The  woman  com- 
plains of  shortness  of  breath,  of  precordial  oppression,  of  a  feeling  of  impending 
death,  and  soon  becomes  restless  again.  Vomiting  begins,  but  usually  is  not  a 
prominent  symptom  until  later.  The  pains  almost  always  cease,  but  if  the  child 
has  not  been  expelled  into  the  abdominal  cavity,  they  may  continue,  though  weaker, 
and  they  may,  though  rarely,  suffice  to  deliver  the  child.  Hemorrhage  from  the 
genitals  now  appears,  but  is  usually  not  profuse.  The  fetal  movements  for  the 
first  few  minutes  are  very  violent,  while  the  child  dies,  then  cease,  a  phenomenon 
which  may  be  observ^ed  with  special  distinctness  when  the  child  has  escaped  from  the 
rent  uterus  under  the  abdominal  wall.  If  the  child  is  delivered  and  the  rupture  un- 
treated, the  woman  may  die  from  primary  hemorrhage,  from  shock,  from  secondary 
hemorrhage  (a  hematoma  bursting),  from  peritonitis,  either  earty  or  beginning  as  late 
as  the  twentieth  day,  or  she  may  recover  unaided  if  the  damage  is  not  great.  The  peri- 
toneal edges  of  the  tear  adhere,  and,  in  the  absence  of  infection,  the  wound  granulates.

THE    PATHOLOGY    OF   LABOR 


A  few  cases  are  on  record  where  the  child,  expelled  through  the  rent  into  the 
peritoneal  cavity,  was  changed  into  a  lithopedion,  as  in  ectopic  gestation. 

Diagnosis.— (A)  Threatened  Rupture. — It  is  vitally  important  that  the  diagnosis 
of  dangerous  thinning  of  the  uterus  be  made  lief  ore  the  rupture  occurs,  because  if 
anything  can  be  done  to  save  the  woman,  it  must  be  done  at  once.  The  findings 
on  examination  are — (1)  A  restless,  excited,  anxious  patient,  high  pulse  (90  to  110), 
irregular  respiration,  temperature  99.6°  to  100.4°  F.,  and,  if  infection  is  beginning, 
101°  to  103°  F.;  (2)  strong  uterine  eontraetion.s  tvithout  proportionate  advance  of  the 
presenting  part;  (3)  the  uterus  hard  and  drawn  up  over  the  child,  which  lies  in  the 

dilated  lower  uterine  seg- 
ment (Fig.  697).  The  fun- 
dus is  thick  and  the  lower 
uterine  segment  soft;  it 
balloons  out  during  the 
pains,  allowing  the  fetal 
body  to  be  outlined  with 
startling  distinctness.  The 
latter  seems  to  lie  under 
the  skin.  This  finding  is 
possible  under  anesthesia 
— the  exquisite  tenderness 
prevents  it  otherwise;  (4) 
a  groove  is  visible  and  pal- 
pable, running  obliquely 
across  the  belly,  higher  on 
the  side  of  the  greatest 
stretching — the  contrac- 
tion ring  (Fig.  697).  It 
may  rise  as  high  as  the 
navel  or  higher,  and  the 
distance  from  the  pubis 
may  be  used  to  estimate 
the  degree  of  thinning  and 
stretching  of  the  lower 
uterine  segment;  (5)  the 
round  ligaments  are  in- 
serted high  on  the  uterus, 
are  hard  and  wiry,  and 
particularly  the  one  on  the 
side  which  is  going  to 
burst  may  be  tense  and 
taut,  like  a  violin  string 
(Fig.  697) ;  (6)  the  uterus 
is  oblique;  (7)  the  bladder 
is  drawn  up  high;  (8)  a 
general  abdominal  t(>nd(Tness  is  present,  but  the  lower  uterine  segment  is  so  sensi- 
tive that  the  woman  will  hardly  allow  it  to  be  touched;  (9)  internal  examination 
will  reveal  the  cervix,  either  imprisoned  in  the  pelvis  and  swollen,  black  and  blue, 
or  drawn  up  out  of  the  pelvis  with  the  vagina  on  the  stretch,  taut  around  the  pre- 
senting part,  and  hot,  reddened,  and  drj'. 

These  findings  on  the  direct  examination  will  (nia])le  every  accoucheur  to  dis- 
cover the  danger  which  threatens  the  woman  in  time  to  institute  proper  treatment. 
Unfortunately,  in  the  latent  ruptures  they  may  be  absent  or  veiled. 

(B)  Actual  Rupture. — The  symptoms  of  the  actual  tearing  of  the  uterus  and

of  the  shock  and  anemia  which  follow  will  almost  ahva3's  ])e  sufficient  to  make  the 
direct  diagnosis,  but  an  examination  of  the  patient  must  be  made  to  confirm  it. 
The  findings  in  cases  of  rupture  of  the  uterus  vary,  of  course,  with  the  time  in  labor 
when  it  occurs,  and  whether  or  not  the  child  is  in  the  uterus  or  in  the  belly  when  the 
examination  is  made.  They  are:  (1)  A  collapsed  patient  with  all  the  signs  of 
anemia  and  of  shock;  (2)  uterine  action  stopped  or  verj-  weak;  (3)  external  hemor- 
rhage, mild  or  severe,  rarely  absent;  (4)  abdominally,  the  child  can  be  felt  with  sur- 
prising distinctness,  lying  right  under  the  belly-wall,  while  the  empty  uterus  is 
pushed  to  one  side,  or  behind,  where  it  is  not  palpable.  If  the  child  has  partly 
escaped,  the  uterine  tumor  is  heart  shaped.  Dulness  in  the  flanks  from  free  blood 
is  very  rarely  determinable.  Tenderness  may  make  the  abdominal  examination 
nugatory;  (5)  externally  the  hematoma  may  be  felt,  or  emphysematous  crackling; 
(6)  internally,  the  ragged  rent  may  be  palpable,  and  intestines  or  omentum  may  fall 
into  the  hand ;  (7)  the  presenting  part  has  disappeared  from  the  inlet  or  has  become 
freely  movable. 

The  author  makes  it  a  rule,  after  every  operative  delivery,  no  matter  how  hard 
or  how  easy,  whether  or  not  symptoms  are  present,  to  examine  the  uterus  with  the 
whole  hand  and  determine,  beyond  the  suspicion  of  a  doubt,  the  extent  and  location 
of  any  injury.     This  practice  cannot  be  too  strongly  recommended. 

Differential  Diagnosis. — As  a  rule,  during  labor,  little  difficulty  is  experienced,  but  some- 
times one  has  to  consider  abruptio  placenta^,  placenta  prajvia,  and  extra-uterine  pregnancy  at  term. 
Tliesc  have  already  been  discussed  under  their  respective  headings.  Collapse  during  or  after  labor 
may  be  due  to  something  else,  but  rupture  of  the  uterus  is  first  to  be  thought  of. 

An  important  diagnosis  to  make  after  delivery  is  whether  the  rupture  is  complete  or  incom- 
plete, since  the  principles  of  the  treatment  depend  on  this.  Abdominally,  little  can  be  found; 
in  rare  instances  a  hematoma  may  be  outlined.  Emphysema  is  not  distinctive,  nor  are  signs  of 
p(>ritoncal  irritation.  Vaginally,  the  presence  of  intestines  or  omentum  is,  of  course,  conclusive, 
but  not  the  discharge  of  peritoneal  fluid,  which  may  be  simulated  by  the  serum  squeezed  out  from 
a  blootl-clot.  The  internal  examination  alone  can  be  relied  on  to  differentiate,  and  here  it  may  be 
necessary  to  use  the  hand  without  a  rubber  glove.  This  is  the  only  instance  where  I  have  had 
to  use  the  bare  hand.  The  fingers  gently  pass  through  the  uterine  portion  of  the  tear,  and  come 
into  a  space  filled  with  soft  clot.  Strands  of  fibrous  tissue,  nerves,  and  sometimes  vessels  span  the 
space,  and  great  care  must  be  exercised  to  prevent  breaking  them.  I  once  felt  the  uterine  artery 
between  my  fingers  pulsating  ominously.  If  the  tear  is  complete,  the  fingers  pass  directly  into 
the  peritoneal  cavity,  which  may  be  recognized  by — (1)  The  smooth,  slippery  surface  of  the  ad- 
jacent uterus  and  of  the  abdominal  wall;  (2)  the  presence  of  gut  and  omentum;  (3)  the  great  free- 
dom of  motion  for  the  fingers;  (4)  the  fingers  may  lift  up  the  abdominal  wall  from  the  inside;  (5) 
outlining  the  edges  of  the  wound.  To  recognize  the  thin,  veil-like  layer  of  peritoneum  over  an  in- 
complete rupture — (1)  Note  if  the  fingers  are  confined  to  a  ragged,  walled  cavity;  (2)  try  to  deter- 
mine the  upper  uterine  end  of  the  rupture,  and  find  if  the  peritoneum  has  been  stripped  off  the 
uterus  iiere;  (3)  bimanually,  determine  if  there  are  any  structures  between  the  hands;  (4)  try  to 
slide  the  (luestionable  layer  of  tissue  over  the  fingers,  or  depress  it  by  the  abdominal  hand  between 
the  two  i^arted  internal  fingers;  (5)  note  the  relation  of  the  gut  to  it.  In  the  last  instance  the 
peritoneum  may  be  so  thin  and  stripped  ofT  the  underlying  structures  so  extensively  that  the  gut 
appears  to  be  within  the  grasp  of  the  fingers,  uncovered.  Here  the  differential  diagnosis  is  not 
so  necessary,  because  in  such  cases  the  thin  veil  of  peritoneum  will  in  all  likelihood  slough  off,  so 
that  the  treatment  is  the  same  as  for  complete.tears. 

It  is  sometimes  necessary  to  decide  if  other  organs  beside  the  uterus — the  bladder,  the  rectum 
and  bowels,  the  omentum^are  involved.  If  there  is  the  least  suspicion  of  such  an  injury,  the 
case  is  to  be  treated  as  if  it  really  were  so.  The  bladder  may  be  examined  with  a  cystoscope.  I 
discovered  one  injury  in  this  way.  The  rectum  may  be  explored,  but  if  any  injury  higher  up  is 
suspected,  the  belly  should  be  opened. 

Prognosis. — This  is  grave  in  all  cases,  but,  fortunately,  the  improvement  of  the 
modern  obstetric  practice,  with  asepsis  and  early  recognition  and  operative  treat- 
ment of  the  accident,  has  effected  a  substantial  reduction  of  the  previous  high  mor- 
tality. Incomplete  ruptures  are  a  little  less  dangerous  than  complete  ones,  but  the 
prognosis  depends  on  so  many  conditions — the  site,  the  extent  and  method  of  in- 
fliction of  the  injury,  the  presence  of  infection,  the  environment  of  the  patient 
(hospital  or  home),  the  kind  of  treatment,  etc. — that  figures  are  practically  useless. 
Of  the  author's  10  cases  of  complete  ruptin'o,  8  died  of  shock  or  sepsis;  of  14  cases  of 
incomplete  tear,  3  died — 2  from  hemorrhage  and  1  from  peritonitis.  Cholmogarof,

ing  on  no  particular  line  of  treatment,  and  Kol)lanck  showed  73  per  cent,  and  78  per 
cent.,  Braun,  G3  per  cent.,  tliat  for  incomplete  tears  ])eing  25  per  cent.  For  the 
child,  the  outlook  is  still  worse.  Unless  the  deliver}'  can  ])e  completed  at  once,  the 
child  is  surely  lost.  When  the  rupture  occurs  at  the  end  of  the  second  stage,  the 
child  may  come  out  alive.  If  it  is  forced  out  into  the  belly,  it  usually  dies  in  a  few 
minutes,  but  three  cases  are  on  record  where  a  hasty  abdominal  section  rescued  it. 

If  the  mother  survives  the  hemorrhage  and  shock,  her  life  depends  on  the 
presence  or  absence  of  infection.  Peritonitis  is  the  rule  because  the  cases  are 
usually  in  the  hands  of  midwives  or  unclean  attendants.  Even  if  she  recovers  from 
this  labor  she  is  threatened  by  a  worse  recurrence  of  the  accident  in  her  next  one. 
Perfect  health  is  never  restored;  the  uterus  remains  large  (chronic  metritis),  the 
laceration  scars  distort  and  displace  it,  and  the  pelvis  is  permanently  the  seat  of 
venous  congestion. 

Treatment. — Prevention  of  rupture  of  the  uterus  is  one  of  the  regular  duties  of 
the  accoucheur,  and  forms  part  of  the  "watchful  expectancy"  so  often  spoken  of  in 
the  treatment  of  labor  cases.  If  a  diagnosis  of  ruptura  uteri  imminens  is  made,  the 
indication  is  to  empty  the  uterus  as  quickly  as  possible,  and,  further,  this  must  be 
done  with  the  least  possible  increase  of  the  intra-uterine  tension,  i.  e.,  with  no  further 
stretching  of  the  already  overstretched  lower  uterine  segment,  cervix,  and  vagina. 
If  the  cervix  is  imprisoned  in  the  pelvis,  it  must  first  ])e  pushed  up,  because  traction 
on  it  from  below  would  stretch  it  still  further  in  the  length  and  cause  the  transverse 
tear  which  was  impending.  If  all  the  conditions  for  forceps  are  fulfilled,  this  is  the 
operation  of  choice,  but  it  may  not  be  forced,  since  the  dragging  down  of  the  child 
may  pull  the  thinned  cervix  apart.  Cranioclasis,  followed  by  cleidotomy  and  evis- 
ceration, is  preferal^le  and  more  humane.  It  is  criminal  to  attempt  version  in  these 
cases.  In  breech  presentations  the  after-coming  head  must  be  carefully  led  through 
the  endangered  portion  of  the  parturient  canal.  In  shoulder  presentations  embry- 
otomy, i.  e.,  evisceration  and  rachiotomy,  is  the  method  of  election.  Since  the  child 
is  nearly  always  dead  or  dying,  the  accoucheur  should  have  no  compunctions  about 
this  operation,  especially  when  version  carries  so  terrible  a  risk  for  the  mother.  In 
cases  where  the  uterus  has  only  just  begun  to  show  evidences  of  thinning  out,  an 
expert  accoucheur  may,  exceptionally,  under  deep  anesthesia  and  in  ideal  surround- 
ings, make  a  gentle  trial  of  version  in  the  hope  of  saving  the  infant.  Under  other 
circumstances  the  mother  is  safest  with  embryotomy.  Cesarean  section  should 
always  be  considered  when  the  child  is  alive,  but  the  conditions  favorable  to  the 
mother,  too,  must  be  present.  Cesarean  section  must  always  be  clone  in  high  de- 
grees of  pelvic  contraction  or  obstruction  of  the  soft  parts.  Pubiotomy  rarely  comes 
into  the  discussion  of  these  cases.     Vaginal  hysterotomy  occasionally  does. 

To  prevent  a  rupture  while  preparing  for  these  operations  the  patient  should 
be  instructed  to  lie  quiet  and  not  to  bear  down.  The  uterus  may  be  supported 
by  a  binder,  but  the  best  remedy  is  a  deep  ether  narcosis  to  paralyze  the  uterus 
until  aid  is  at  hand.  Under  no  circumstances  may  a  woman  threatened  with  rupture 
of  the  uterus  be  transported  to  a  hospital.  I  have  known  the  tear  to  occur  on  the 
way  from  the  jolting  over  bad  roads. 

Treatment  after  Rupture. — If  the  woman  is  in  a  well-equipped  maternity  when 
the  rupture  occurs,  an  attempt  should  be  made  to  save  the  child,  either  bj^  a  quick 
delivery  from  below  or  by  abdominal  section.  Extreme  shock  and  collapse  may 
forbid  the  rapid  emptjdng  of  the  uterus  which  might  precipitate  the  fatal  end.  It 
is  not  advisable  to  transport  a  parturient  to  a  hospital  after  rupture,  but  this  may 
be  necessary,  if  the  child  has  escaped  into  the  peritoneal  cavity,  l)ecause  then  the 
proper  treatment  is  laparotomy,  which  cannot  always  be  done  at  home.  During 
the  transport  the  abdomen  is  to  be  supported  by  a  well-padded  binder  and  steadied 
by  the  hands  of  a  medical  attendant  if  the  jolting  of  the  ambulance  is  excessive. 
When  it  is  necessary  to  treat  the  case  at  home,  the  child  must  be  delivered  through 


THE    ACCIDENTS    OF    LABOR  757 

the  natural  passages,  even  though  there  is  real  danger  of  making  the  rent  larger  and 
of  rupturing  important  vessels. 

Much  difference  Avill  be  found  in  the  treatment  of  ruptured  uterus  between  that 
of  the  si)ecialist  in  his  well-equipi)ed  maternity  and  the  general  practitioner  without 
such  advantages.  The  following  methods  have  been  in  use:  (1)  Extract  the  fetus 
through  the  vagina;  replace  intestines;  morphin,  ergot,  ice-bag  on  abdomen; 
(2)  extract  the  fetus  through  the  vagina,  replace  intestines,  drain  (not  tight  packing) 
the  rent  and  the  peritoneal  cavity  with  gauze  or  rubber  tube;  ergot,  ice-bag,  mor- 
phin; (3)  the  same,  then  sew  up  the  rent  from  below  and  drain  part  of  the  tear  with 
gauze ;  ergot,  ice-bag,  etc. ;  (4)  deUvery  from  below,  followed  by  vaginal  extirpation 
of  the  uterus;  (5)  laparotomy,  remove  fetus  and  placenta,  sew  up  rent,  and  drain 
from  below;  (6)  the  same,  but  with  amputation  of  the  uterus  or  total  extirpation, 
with  vaginal  drainage. 

The  first  four  methods  are  applicable  when  the  child  may  be  delivered  per 
vaginam,  and  where  the  rupture  is  discovered  only  after  delivery.  If  it  is  not 
possil)le  or  safe  to  deliver  the  child  from  below,  laparotomy  must  be  done,  the 
child  and  the  placenta  removed,  and  the  uterus  and  hollow  organs  dealt  with  ac- 
cording to  conditions.  If  the  case  is  clean,  the  rent  in  the  uterus  maj'  be  repaired, 
and  drainage  through  the  vagina  with  gauze  secured;  if  it  is  septic  or  presumably  so, 
extirpation  or  amputation  of  the  uterus  is  to  be  performed,  with  drainage  of  the 
pelvis  from  below\  If  the  hemorrhage  is  profuse  and  not  easily  controlled  Ijy  clamps 
and  suture,  the  uterus  had  ])est  be  removed.  Whether  to  extirpate  or  only  to  ampu- 
tate depends  on  the  extent  and  location  of  the  injury  and  the  condition  of  the  par- 
turient, amputation  being  quicker  than  total  extirpation. 

After  delivery,  when  the  question  arises  w^hether  to  open  the  belly  or  treat 
the  case  per  vaginam,  these  things  must  be  considered:  (1)  The  statistics;  (2) 
the  environment  of  the  patient;  (3)  her  condition  as  regards  infection  and  bleed- 
ing; (4)  the  skill  of  the  operator.  Statistics,  as  usual,  are  unreliable  guides, 
KUen  finding  that  44  per  cent,  recovered  with  laparotomy,  while  only  39  per  cent, 
with  drainage,  and  Kolaczek  finding  that  only  25  per  cent,  recovered  after  lapa- 
rotomy, while  39  per  cent,  recovered  with  drainage.  In  poor  surroundings  drain- 
age is  better  than  celiotomy,  and  since  it  is  dangerous  to  transport  these  patients, 
the  argument  for  drainage  is  stronger.  In  cases  of  infection  it  is  hard  to  de- 
cide, but  the  majority  of  authorities  seem  to  be  on  the  side  of  extirpation  of  the 
uterus,  with  most  thorough  drainage  below.  Vaginal  extirpation  should  show 
the  best  results  here.  In  the  milder  cases  hemorrhage  may  be  controlled  by  light 
tamponing  of  the  rent,  but  if  severe,  the  bell}'  must  be  opened.  When  injur}-  to 
adjacent  viscera  is  suspected,  immediate  laparotomy  is  demanded.  In  the  hands  of 
the  general  practitioner  drainage  is  the  operation  of  choice,  while  in  the  equipped 
maternity  more  radical  measures  may  be  attempted.  Scipiades,  of  Budapest,  in 
1910,  l)asing  his  judgment  on  an  experience  of  97  cases,  says  drainage  is  l)est  even  in 
hospitals.  Aly  own  experience  in  hospital,  dispensary,  and  consultation  practice 
has  convinced  me  that  drainage  of  the  peritoneum  and  the  tear  is  the  best  general 
treatment,  and  that  laparotomy  is  to  be  done  to  meet  special  indications.  In 
clean  cases  part  of  the  rupture  should  be  united  Ijy  suture.  This  is  accomplished 
by  exposing  the  wound  with  very  broad  specula,  and  pulling  clown  its  edges  with  the 
cervix  forceps  (Figs.  689  and  690).  In  one  case,  in  1898,  in  order  to  bring  the  deepest 
portions  of  the  rent  within  reach,  I  detached  the  bladder  from  the  cervix  in  a  manner 
similar  to  that  of  the  vaginal  cesarean  section.  After  the  tear  is  nearly  all  sewed 
the  space  above  is  drained  with  a  few  strips  of  gauze  or  a  soft-rubber  tube,  as 
thick  as  the  finger. 

I  have  not  yet  had  an  oi^jjortunity  to  use  the  IMomburg  belt  in  a  case  of  rupture 
of  the  uterus,  but  can  appreciate  that  it  might  be  valuable  to  arrest  hemorrhage 
while  the  rent  is  being  examined  and  repaired. 


758  THE    PATHOLOGY    OF   LABOR 

Incom'plete  ruptures  are  best  treated  b}-  light  jiaeking.  If  the  rent  is  packed  too 
tightly,  the  thin  peritoneum  may  be  burst  through,  or  may  split  over  the  tampon 
during  the  trans]:)ort  from  table  to  bed,  or  during  the  restless  tossing  of  the  partu- 
rient. If  the  peritoneum  is  lifted  off  its  attachments  for  a  great  extent,  especially 
in  multii:>le  ruptures;  if  there  is  a  suspicion  of  infection;  if  the  hemorrhage  is  ob- 
stinate; if  the  wound  is  complicated — the  case  is  to  be  treated  like  a  complete 
rupture.  It  may  be  possible  to  reach  the  field  of  an  incomplete  rupture  by  an 
incision  similar  to  that  made  for  ligating  the  internal  iliac  artery. 

After-treatment. — Ergot  and  hydrastis  will  help  to  keep  the  uterus  contracted. 
A  j&rm  abdominal  binder  should  be  applied,  though  if  it  is  needed  for  counterpressure 
to  aid  a  tampon  in  stopping  hemorrhage  not  much  may  be  expected.  I  got  good 
results  in  one  case  bj'  sitting  by  the  woman's  side  and  holding  the  uterus  down 
against  the  tampon  for  two  hours.  The  gauze  is  removed  on  the  third  or  fourth 
day,  and  a  smaller  strip  inserted  or  a  tul)e  substituted.  It  is  wise  not  to  let  the 
wound  close  too  rapidly.  If  signs  of  infection  appear,  a  vaginal  examination  is 
required  to  determine  the  presence  of  an  exudate. 

Since  the  site  of  a  healed  rupture  of  the  uterus  is  not  strong,  the  muscular  fibers 
near  it  being  usually  atrophied  and  the  scar  frial:)le.  it  is  l:)est  to  instruct  the  patient 
that  in  a  subsequent  pregnancy  she  should  spend  the  last  four  weeks  in  a  maternity. 
As  soon  as  labor  declares  itself  cesarean  section  should  be  performed.  If  this  advice 
is  unheeded,  the  accoucheur  should,  when  called  during  labor,  terminate  the  case 
with  forceps  as  soon  as  the  conditions  are  present.  Induced  la]:)or  is  slightly  less 
dangerous  than  labor  at  term,  but  if  pelvic  obstruction  is  to  be  overcome,  it  is  not, 
and  the  abdominal  delivery  at  term  is  imperative.  The  induction  of  abortion  for 
this  indication  alone  is  not  allowable. 


RUPTURE  OF  THE  UTERUS  DURING  PREGNANCY 

This  is  one  of  the  rarest  accidents  of  pregnancy,  if  one  exchides  perforation  of  the  uterus  by 
criminal  abortionists.  Baisch,  in  1903,  collected  78  cases.  A  healthy  uterus  will  tear  only  under 
the  most  violent  indirect  injury;  but  if  the  muscle  is  diseased,  it  may  give  way  during  the  natural 
growth  of  pregnancy,  or  during  one  of  the  contractions  of  the  uterus,  or  from  tlie  shock  of  a  fall, 
a  cough,  etc.  Ruptures  of  the  uterus  during  pregnancy  are  to  be  di\'ided,  as  in  labor,  into  spon- 
taneous and  trainiiatic.  The  latter  group  must  be  further  divided  into  those  due  to  direct  injury 
applied  to  the  uterus,  and  those  occurring  indirectly,  as  from  a  fall  or  straining  of  any  kind.  Simple 
spontaneous  rupture  may  occur  from  yielding  of  the  scar  of  a  previous  cesarean  section,  or  from 
previous  rupture,  injury,  or  from  gynecologic  operations  (fibroid,  curetage,  etc.);  thinning  of  the 
uterine  wall  from  manual  removal  of  the  placenta,  especially  if  repeated;  hypoplastic  uteri;  mal- 
formed uteri,  as  single  or  double  horned;  interstitial  pregnancy;  actual  disease  of  the  w'all,  car- 
cinoma, hydatid  mole,  fatty  and  hyaline  degeneration,  previous  infection,  and  small-cell  infiltra- 
tion; growth  of  placental  villi  into  the  uterine  wall;  abruptio  placenta^  (the  uterus  may  burst 
over  the  retro  placental  hematoma);  displaced  and  adherent  uterus;  in  short,  the  same  factors 
which  predispose  to  rupture  during  labor. 

Examples  of  direct  traumatism  are:  Puncture  of  the  uterus  by  sounds,  curets,  or  other  imple- 
ments, used  in  operations  or  to  produce  abortion,  by  bullet,  the  horn  of  a  steer,  etc.  Indirect 
traumatism  is  often  the  cause,  but  often  a  disease  of  the  uterus  preexists,  because  the  normal  organ 
can  withstand  much  insult  without  injurj^,  as  witness  the  case  of  Hofmeier,  where  the  woman  fell 
from  a  fourth-story  window  without  rupture,  and  the  one  where  a  drunken  man  jumped  upon  the 
prostrate  woman's  abdomen  without  causing  abortion. 

Clinical  Course. — Baisch  found  .31  cases  of  rupture  during  the  first  five  months  of  gestation, 
and  in  these  the  uterine  wall  was  diseased.  In  the  later  ruptures  scar  tissue  was  usually  foimd. 
The  symptoms  resemble  those  of  ruptured  extra-uterine  pregnancy,  but  the  shock  is  usually  more 
marked,  especially  when  external  violence  is  the  causative  agent.  Pain  in  the  abdomen  is  the  rule, 
and  labor  pains  may  occur — this  when  rupture  is  incomplete.  These  contractions  complete  the 
tear  and  expel  the  child  out  of  the  uterus,  after  which  they  subside.  When  the  peritonitis  begins, 
pain  recommenc(!s,  but  usually  the  patient  complains  of  a  tender  body  in  the  abdomen  from  the 
start.  Vomiting,  hiccup,  and  other  signs  of  peritoneal  irritation  are  usually  i)resent,  tog(>ther  with 
signs  of  internal  hemorrhage. 

In  Leopold's  and  Henrotin's  cases  gestation  continued,  with  the  child  among  the  bowels,  the 
cord  issuing  from  the  hole  in  the  uterus,  but  these  are  exceptional,  the  rule  being  that  the  child 
die.s,  becomes  infected,  and  peritonitis  closes  the  scene.  It  is  pos.sible  that  a  lithopedion  may  re- 
sult. The  hemorrhage  may  be  internal,  external,  or  both;  sometimes  the  child  tampons  the  rent, 
and  there  is  no  hemorrhage  at  all^  so  that  a  diagnosis  cannot  be  made  until  the  belly  is  opened. 


THE   ACCIDENTS    OF   LABOR 


759 


Hematomata  are  rare,  because  the  tears  are  usually  fundal.  Kupture  may  sometimes  occur  in 
the  anterior  or  posterior  wall,  and  also,  but  rarely,  in  the  lower  part  of  the  uterus.  While  the 
labor  pains  are  foroinfi  tlic  child  out  through  the  tear,  a  bag  of  waters  may  form  over  the  os — the 
child  may  be  even  delivercfl  through  the  vagina  before  the  fundal  tear  is  completed. 

Instrumental  perforations,  if  done  aseptically  and  not  large,  bring  on  abortion  and  may  heal 
unnoticed;  if  done,  as  u.sual,  without  asepsis,  they  cause  decomposition  of  the  uterine  contents 
and  peritonitis.     (See  Septic  Abortion.) 

Diagnosis. — This  is  almost  always  very  difficult,  but  since  most  of  the  conditions  which

simulate  the  accident  require  laparotomy  anyway,  it  is  not  absolute!}-  essential.  To  be  considered 
here  are  torsion  of  a  tumor  near  the  uterus,  rupture  of  the  liver,  gall-bladder,  or  spleen,  ileus,  rup- 
tured ectopic  gestation,  abruptio  placentir,  and  placenta  previa. 

The  treatment  is  laparotomy  as  soon  as  the  diagnosis  is  made  or  becomes  even  only  probable. 


INVERSION  OF  THE  UTERUS 

Fig.  G99  shows  a  complete  inversion  or  turning  inside  out  of  the  uterus,  together  with  pro- 
lapse, i.  e.,  prolapsus  uteri  inversi.  Lesser  degrees  occur,  and  only  the  placental  site  may  be  de- 
pressed, as  in  Fig.  708,  p.  772 — the  so-called  atony  of  the  placental  site.  AH  grades  between 
these  two  extremes  are  observed,  and  are  called  incomplete  or  partial  inversions,  the  most  com- 
mon of  which  are  tho.sc  in  which  the  fundus  comes  to  lie  in  the  vagina  just  within  the  introitus, 
and  feels  like  a  soft,  large,  globular,  libroid  polyp.  The  placenta  may  still  be  attached,  or  only 
partially  adherent.  If  the  inversion  occurs  after  the  third  stage,  the  naked  uterus  lies  in  the 
vagina  or  may  be  expelled  outside,  in  which  case  the  open  sinuses  and  tubal  ostia  are  visible. 
In  the  "inversion  funnel"  from  the  abdominal  side  the  tubes,  ovaries,  the  round  and  broad 
ligaments,  sometimes  the  gut  and  omentum,  may  be  seen. 

Eliology. — In  one  of  the  author's  cases,  during  the  removal  of  the  placenta,  the  uterus  was 
felt  to  contract,  the  contraction  ring  opened  outward,  a  condition  shown  in  Fig.  700  appearing  for 
a  few  moments.  The  view  that  an  inversion  could  be  thus  produced  by  contraction  of  the  fundus, 
with  relaxation  of  the  lower  jjortions  of  the  uterus,  was  held  by  Kokitansky,  Duncan,  and  others, 
but  Schauta  strongly  a.^^serted  the  contrary — that  it  was  atony  of  the  uterus  which  caused  the 
accident.  While  atony  of  the  organ  may  cause  the  majority,!  am  convinced  that  the^new  of  Ro- 
kitansky  is  correct  in  some  cases.  An  atonic  uterus  may  become  inverted  by  a  sudden  action  of 
the  abdominal  muscles,  increasing  intra-abdominal  pressure,  such  as  bearing  down  to  express  the 
placenta,  turning  in  bed,  sitting  up,  coughing,  raising  the  hips  to  allow  a  clean  sheet  to  be  placed. 
Inversion  from  such  causes  is  called  spontaneous.  Viohnf  inversion  may  be  due  to  traction  on  the 
umbiUcal  cord  in  the  effort  to  remove  the  placenta  (24  of  47  cases  of  Vogel),  traction  on  part  of  the 
placenta  or  on  the  membranes,  and  too  powerful  Crede  expre.>*sion  of  the  placenta.  Spontaneous 
inversion  may  result  from  pulling  on  the  too  short  cord  by  the  child  during  natural  delivery.  While 
many  cases  are  reported  as  spontaneous,  probably  most  of  them  are  the  result  of  errors  of  art.

THE    PATHOLOGY    OF   LABOR 


Inversion  of  the  uterus  is  rare  ui  liospitals.  Braun.  in  250,000  labors,  ilid  not  sec  one,  and  in 
Dublin  only  one  was  observed  in  190.000  consecutive  labore.  Most  of  the  cases  occur  in  private 
practice  but  the  accident  is  exceedingly  rare.  It  uiav  occur  in  abortion  as  early  as  the  fourth 
month.  Holmes  having  had  a  case  at  the  fifth  month,  and  it  mav  appear  on  the  second,  sixth,  even 
the  fatteenth,  day  after  delivery. 

Symptoms.— As  a  rule,  the  inversion  is  gradual,  beginning  as  a  little  depression,  and  then 
suddenly  the  fundus  drops  into  the  vagina  (Fig.  701).  If  traction  on  the  cord  has  been  made 
the  niovement  is  more  abrupt.  The  patient  utters  a  sharp  crv  and  beai-s  down,  the  latter  having 
a  tendency  to  increase  the  prolapse.  Shock  is  almost  alwavs  present,  certainlv  if  the  uterus  turned 
inside  out  suddenly,  and  is  due  to  the  stretching  of  the  peritoneum  and  the  nerves  of  the  broad 
ligaments,  perhaps  also  from  the  reduction  in  intra-abdominal  tension  and  consequent  downward

displacement  of  the  diaphragm,  the  heart,  etc.  Profuse  hemorrhage  is  the  rule,  because  the  pla- 
centa has  almost  always  been  either  partly  or  completelv  detached,  but  it  mav  be  absent  if  the 
organ  is  still  adherent  to  the  invertetl  uterus.  Shock  is  disproportionate  to  blood  loss.  If  the 
uterus  contracts,  especially  if  the  cervi.x  snaps  together  aroimd  the  extruded  fundus,  the  bleeding 
niay  be  slight,  but  this  is  the  exception.  In  rare  instances  both  collapse  and  severe  bleeding  are 
absent,  and  the  condition  is  discoveretl  only  at  a  subsequent  examination.  If  the  woman  does  not 
die  froni  shook  or  hemorrhage,  the  inverted  fundus  may  slough  off,  resulting  in  tleath  or  recoverv; 
it  may  be  infected,  resulting  in  septicopyemia,  or  it  mav  undergo  involution  aiul  come  under  late 
treatment,  or  it  may.  spontaneously,  and  without  e-xplainable  cause,  be  reinverted.  Such  cures

chronic  cases  the  fundus  in  the  vagina  atrophies  and  becomes  covered  with  a  dry,  shghtly  hornified 
cpitheUum,  and  is  often  the  seat  of  erosions  and  ulcers.  Menorrhagia,  leukorrhca,  and  irregular 
bleeding  are  often  complained  of,  with  dragging  pains  in  the  back  and  a  feeling  of  bearing  down,  but, 
remarkably,  one  or  all  of  these  symptoms  may  be  wanting. 

Diagnosis. — If  only  the  attendant  would  bear  this  accident  in  mind,  there  need  be  no  diffi- 
culty in  making  the  diagnosis  on  the  direct  examination.  A  large,  roundish  tumor  in  the  vagina, 
with  absenc(>  of  th(>  fundus  uteri  from  its  proper  place,  in  the  presence  of  shock  and  hemorrhage, 
will  clear  up  the  situation  at  once.  It  may  be  possible  to  feel  the  inversion  funnel  from  the  abdo- 
men after  the  bladder  is  emptied.  In  the  differential  diagnosis  fibroid  polyp,  adherent  placenta, 
and  total  atony  of  the  uterus  are  to  be  considered, 
and  a  careful  bimanual  examination  will  easily  decide 
between  them.  The  inverted  fundus  has  been  torn 
off  under  the  notion  that  it  was  the  placenta  alone; 
it  has  b(>en  cut  off  as  a  tumor,  and  the  whole  uterus 
has  been  i)ulled  out  as  a  second  twin!  If  the  fundus 
is  prolapsed,  the  bright-red,  rough,  bleeding  endo- 
metrium, or  the  placenta,  cannot  fail  to  tell  what 
has  happened.  In  debating  the  causes  of  postpartum 
shock  inversio  ut(>ri  must  be  considered  with  rupture 
of  the  uterus,  hemorrhage,  etc. 

Prognosis. — This  is  better  now  than  formerly, 
by  grace  of  asepsis  and  better  obstetric  practice  in 
general.  Crosse,  in  18-43,  found  that  80  of  109  re- 
ported cases  died;  Vogel,  in  1900,  reported  only  22 
per  cent,  mortality.  Even  some  of  the  cases  where 
the  uterus  has  been  torn  off  recover  if  infection  is 
absent.  Reposition  improves  the  outlook.  It  may 
be  possible  even  after  twenty  years. 

Treatment. — Although  inversion  of  the  uterus 
is  rare,  the  accouchem-'s  routine  technic  in  handling 
labor  cases  should  comprise  means  for  its  prevention. 
Traction  on  the  cord  must  be  avoided,  and,  while 
drawing  the  membranes  off  the  uterine  wall,  the  out- 
side hand  must  lie  on  the  fundus  and  assure  its  contraction.  Atony  of  the  uterus  postpartimi  is 
to  be  rectified  as  soon  as  possible.  In  turning  the  newly  delivered  woman  from  side  to  side,  or 
when  she  raises  her  hips  for  the  removal  of  soiled  bed-clothes,  the  bed-pan,  the  rubber  pad,  etc., 
the  attendant  must  lay  a  hand  on  the  uterus  and  be  sure  that  it  is  firmly  conti-acted.  During  the 
manual  removal  of  the  placenta  the  first  indications  of  inversion  are  to  be  corrected. 

^^'hat  to  do  in  acute  cases  requires  deliberation,  because  if  the  attempt  is  made  to  put  the 
uterus  back  while  the  woman  is  in  deep  shock,  the  delicate  balance  will  be  turned  against  her. 
Here  it  is  better  to  replace  the  fundus  in  the  vagina,  pack  the  latter  firmly,  and  let  the  parturient 
rally.     If  bleeding  is  going  on,  however,  it  may  be  necessary  to  risk  the  added  shock  in  order  to

stop  it.  Ether  is  the  anesthetic  of  choice,  but  sometimes  only  a  little  encouragement  is  required 
to  enable  the  woman  to  stand  the  operation.  The  shoulders  should  be  raised  a  little  to  avoid  air 
embolism.  It  is  best  to  remove  the  placenta  cleanly,  before  n-jrosition  is  attempted,  but  if  the 
case  seems  favorable,  the  removal  of  the  jilacenta  may  be  done  after  the  uterus  is  returned.  If  the 
attendant  feels  that  the  surroundings  and  his  assistance  do  not  justify  his  interference,  the  external 
portion  of  the  mass  may  be  returned  to  the  vagina  and  the  latter  packed,  to  await  the  arrival  of 
help  or  during  transport  at  i(»i  of  th(>  patient  to  a  maternity.  Spontaneous  reinversion  may  thus 
occur.     It  may  be  wise  to  tSus  tampon  until  the  woman  has  recovered  from  the  shock.

THE    PATHOLOGY    OF   LABOR 


The  technic  of  the  operation  in  acute  cases  is  simple  (Fig.  702).  While  the  whole  mass  lies 
in  the  grasp  of  the  hand,  the  fingers  spread  out  the  constricting  portion  of  the  uterus,  and  the  pahn 
pushes  up  on  the  inverted  funckis — all  this  in  the  ilirection  of  the  axis  of  the  pelvis,  well  forward, 
to  avoid  the  sacrum.  The  mana'uver  maybe  aided  by  the  outside  hand  dilating  the  funnel.  It 
may  be  best  to  push  up  one  side  of  the  uterus  first, — a  sort  of  taxis, — replacing  first  the  ])art  which 
came  down  last.  Great  care  is  to  be  exercised  to  avoid  ])uncturing  the  soft  atonic  uterine  wall. 
It  occurs  surprisingly  easily.  Deep  anesthesia  nuist  l)e  induced  if  there  is  a  tendency  to  spasm  of 
the  constricting  portion,  and  the  operation  may  be  neither  prolongefl  nor  forced.  It  is  better  then 
to  pack  the  vagina  lightly  with  gauze,  surrounding  a  colpeurynter,  which  latter  is  then  filled  with 
sterile  water.  Treatment  with  the  colpeurynter  is  very  successful,  but  sometimes  several — as  high 
as  20 — applications  may  be  needed.  The  colpeurynter  is  left  from  twelve  to  thirty  hours,  and  the 
foot  of  the  bed  is  elevated.  Gentleness,  asepsis,  and  patience  are  the  watchwords.  After  reposi- 
tion it  is  wise  in  all  cases  to  tampon  the  uterovaginal  tract.  "While  the  colp(>urynter  is  most  suc- 
cessful in  the  early  cases,  it  should  always  be  tried  before  resorting  to  operative  measures,  even  for 
very  chronic  inversions.     In  the  last  class  it  may  be  necessary  to  employ  the  knife,  and  then  Kiist- 


FiG.  702. — Diagram  Showing  Method  of  Replacing  Inverted  Uterus. 
After  the  whole  hand,  grasping  the  uterine  body,  has  replaced  same  in  vagina,  the  constricting  cervical  ring  is 
spread  by  means  of  the  finger.s  and  thumb,  while  the  palm  of   the  hand  forces  up  the  fundus  in  the  directions  indicated 
by  arrows.     The  outside  hand  aids  to  dilate  the  funnel. 

ner's  operation  or  one  of  its  modifications  may  be  used.  Hirst  advises  splitting  the  cer\'ix  pos- 
teriorly, since  this  forms  the  constricting  ring  in  old  cases,  and  then  to  replace  the  uterus,  or  if  this 
is  impossible,  to  prolong  the  cut  onto  the  posterior  wall  of  the  uterus,  all  the  incisions  to  be  re- 
paired after  reposition.  If  the  incision  on  the  posterior  wall  of  the  uterus  is  long,  it  may  be  neces- 
sary to  pull  tlie  replaced  and  retroverted  uterus  down  through  an  opening  in  the  ciddesac  for 
suture.  Prilling  this  operation,  vaginal  extirpation  of  the  uterus  may  be  required.  In  acute  cases 
such  operations  are  almost  never  needed,  sepsis,  gangrene,  or  intractable  bleeding  giving  the  few 
rare  indications.  When  extirpation  is  done  it  is  best  to  split  the  fundus  to  avoid  injury  to  struc- 
tures which  may  have  fallen  into  the  funnel,  and  to  obtain  easier  access  to  the  broad  ligaments.

CHAPTER  LX 
INJURIES  TO  THE  BLADDER,  RECTUM,  ETC. 

THE  BLADDER 
During  laborthe  bladder  is  drawoi  up  with  the  unfolding  lower  uterine  segment, 
and,  when  overfilled,  forms  a  rounded  tumor  aljove  the  pubis,  extending  sometimes 
even  above  the  navel.  It  may  be  mistaken  for  the  dilated  lower  uterine  segment 
and  contraction  ring.  The  full  bladder  may  prevent  delivery  by  weakening  uterine 
action,  by  making  it  too  painful  or  impossible  for  the  woman  to  bear  do^\Ti,  and,  if 
it  is  filled  before  the  head  has  entered  the  pelvis,  by  preventing  engagement.  Cathe- 
terization will  make  the  diagnosis  and  cure.  Tumors  of  the  bladder  have  caused 
dystocia,  as  also  have  vesical  calculi.  The  head  may  crush  them  against  the  bone  and 
break  them,  or  the  vaginovesical  wall  may  be  rubbed  through,  causing  fistula.  Such 
obstructions  should  be  pushed  up  out  of  the  pelvis  with  the  patient  in  the  knee- 
chest  position,  and  if  this  is  not  possible,  removed  per  vaginam.  Varices  of  the 
bladder  may  rupture  during  pregnancy  and  labor.  A  kidney  may  be  displaced  and  be- 
come adherent  over  the  inlet,  causing  dystocia.  Horseshoe  kidney  has  thus  been  ob- 
served, but  it  need  not  give  trouble.  Cystocele  may  come  down  before  the  ad- 
vancing head  and  delay  delivery.  It  has  been  punctured  for  the  l)ag  of  waters,  and 
torn  off  as  a  tumor.  The  cystocele  is  not  so  much  to  be  feared  as  the  abruption  of 
the  base  of  the  bladder  from  its  pubic  attachments.  The  duplication  of  the  con- 
nective-tissue strands  which  radiate  from  the  neck  and  anterior  wall  of  the  bladder 
to  the  pubis  and  ligamentum  arcuatum — the  so-called  pubovesical  ligaments — are 
stretched,  separated,  and  torn,  allowing  a  descensus  of  the  bladder.  In  addition 
the  fibers  between  the  bladder  and  vagina  and  those  in  the  base  of  the  broad  liga- 
ments which  support  the  bladder  are  also  disrupted,  all  of  which  causes  cystocele 
and  prolapsus  vesicae.  Unfortunately,  little  can  be  done  during  labor  to  prevent 
this  do\\Tiward  dislocation  of  the  lower  half  of  the  bladder.  The  protruding  organ 
may  be  gently  pushed  ])ack  above  the  advancing  head,  and  in  a  few  cases  I  have  done 
episiotomy  to  deflect  the  head  from  the  posterior  surface  of  the  pul^is  and  thus  re- 
lieve the  crowding  here.  For  this  purpose  the  operation  has  not  been  often  enough 
performed. 

FISTULAS 

Fidulas  are  false  passages  between  adjacent  hollow  organs,  and  in  the  pelvis 
are  almost  always  due  to  labor,  but  cancer,  etc.,  may  ulcerate,  leaving  such  defects, 
while  foreign  bodies,  such  as  pessaries  or  olijects  introduced  for  purposes  of  mastur- 
bation, sometimes  do  the  same.  Fistulas  due  to  laljor  are  getting  rarer  every  year 
by  grace  of  the  better  practice  of  obstetrics.  In  my  student  days  such  operations 
were  not  uncommon — now  they  are  curiosities. 

Pressure  necrosis  of  the  Ijladder  results  from  prolonged  compression  between 
the  head  and  the  pelvis.  This  was  discussed  under  Contracted  Pelvis.  Usually 
the  vaginovesical  septum  is  caught  between  the  two  hard  objects,  and  as  the  result 
of  the  prolonged  arterial  anemia,  the  area  under  the  compression  necroses  and  is 
cast  off  as  a  slough  in  the  first  week  of  the  pucrperium,  causing  incontinence  of 
urine.  If  the  cervix  is  not  dilated,  but  caught  in  the  zone  of  compression,  the  re- 
sulting fistula  will  be  cervicovesical,  perhaps  utero vesical,  or  ureterocervicovesico- 
vaginal.     All  sorts  of  combinations  occur  (Fig.  703).     Without  doubt  bacteria 

763 


764 


THE    PATHOLOGY    OF   L.\BOR 


aid  in  causing  the  necrosis.  In  their  absence  the  tissues  tolerate  much  more  pres- 
sure. Fistulas  are  caused  also  by  direct  traumatism,  an  instrument  being  punched 
through  the  bladder  or  cutting  the  ureter,  or  from  a  wound  of  the  uterus  extending 
into  the  Ijladdci"  or  involving  the  ureter.  Forceps,  the  sharp  hook,  or  the  cranioclast 
has  thus  torn  great  gashes,  and  sharp  spicule  of  bone  in  the  operation  of  crani- 
otomy have  cut  deeply  into  the  soft  parts.  Posteriorly,  the  cervix  may  be  caught 
between  the  head  and  the  promontory,  or  the  rectum  may  be  compromised.  In  the 
former  case  adhesion  of  the  uterus  to  the  promontory  may  result,  or,  if  the  tissue 
necroses,  perforation  and  peritonitis,  in  the  latter  case,  rectovaginal  fistula,  which 
is  rare. 

The  prevention  of  fistulas  has  already  been  considered.     Knowing  the  causa- 
tion, and  by  observing  that  the  portions  of  the  parturient  canal  belo^  the  point  of

compression  are  becoming  swollen,  the  suspicion  of  danger  is  grounded.  Palpation 
of  the  thin  portion  and  bloody  urine  confirm  it. 

Immediate  delivery  as  soon  as  danger  is  recognized  is  the  treatment,  but  the 
delivery  itself  must  be  a  protective  one.  After  delivery  the  bladder  is  catheterized, 
and  the  fact  that  there  is  no  perforation  established;  then,  if  the  possibility  of  too 
long  compression  and  the  fear  of  a  fistula  by  necrosis  are  entertained,  the  woman 
must  be  instructed  to  urinate  regularly  every  four  hours,  or  the  bladder  must  be 
emptied  so  often,  with  a  view  to  avoid  further  danger  of  sloughing.  Hexamethy- 
lentetramin,  in  5-grain  doses,  is  administered  four  times  a  day  as  a  prophylactic. 

Infection  often  accompanies  such  injury,  which  is  unfortunate,  because  the 
scars  which  result  from  the  ulceration  radiate  to  the  sides  of  the  pelvis,  even  to  the 
bone,  and,  by  contracting,  pull  open  the  fistula  and  prevent  its  closing,  also  render-

ing  difficult  the  operations  for  cure.  If  sloughing  of  the  compressed  area  ensues, 
the  administration  of  urinary  antiseptics  should  l)e  kept  up,  ])ut  l)ladder  irrigations 
are  unnecessary,  since  tliere  is  free  drainage.  The  development  of  eczema  from  the 
continuous  dribbling  of  urine  is  prevented  by  proper  nursing.  A  thick  salve  con- 
taining carbonate  of  zinc,  zinc  oxid,  and  vaselin  is  useful.  Later  a  urinal  may  be 
worn.  Small  fistulas,  especially  of  the  traumatic  variety, — that  is,  those  perfora- 
tions not  attended  with  extensive  necrosis  and  radiating  scars, — often  heal  spon- 
taneously. Operation  is  not  to  be  performed  until  the  parts  are  thoroughly  healed 
and  devascularized,  that  is,  about  four  months  postpartum.  Suture  at  this  time, 
I  have  found,  gives  the  Ijcst  results.  Although  properly  belonging  here,  the  opera- 
tions for  the  repair  of  fistulas  may  not  ])e  discussed  because  of  the  lack  of  space. 

If  a  woman  whose  fistula  has  been  successfully  repaired  becomes  pregnant  again, 
abortion  may  not  be  induced,  but  the  atlvisability  of  cesarean  section  at  term  should 
be  debated  with  the  family.  The  healing  of  fistulas  is  so  precarious  that  this  opera- 
tion should  be  performed,  certainly  if  the  original  fistula  was  a  complicated  one. 
Only  too  often  the  trauma  of  the  labor  reopens  the  old  wound  and  a  new  operation 
may  not  be  at  once  successful.  "^ 

INJURIES  TO  THE  RECTUM 

Rectovaginal  fistulas  the  result  of  compression  necrosis  and  direct  injury  by 
instruments  or  spicules  of  bone  have  been  referred  to,  as  also  have  been  those  cases 
where  the  rectovaginal  septum  gives  way  over  the  advancing  presenting  part,  head, 
arm,  or  breech,  and  the  latter  appears  at  the  anus.  Splitting  of  the  mucous  mem- 
brane of  the  rectum  or  of  the  anus  is  not  rare,  and  results  in  fissures  which  may  cause 
painful  defecation,  bleeding,  even  local  infections.  Injury  to  the  rectum  may  be 
produced  by  Ritgen's  and  Olshausen's  manoeuvers  for  delivery  of  the  head.  With- 
out doubt  much  of  the  pain  of  delivery  is  due  to  stretching  and  dislocation  of  the 
rectum  and  of  the  fourth  sacral  nerve,  which  supplies  the  levator  ani.  The  rectum 
may  be  implicated  in  rupture  of  the  uterus. 

THE  PELVIC  JOINTS  AND  BONES 

Softening  and  relaxation  of  the  pelvic  joints  have  already  been  discussed,  and 
the  value  of  this  factor  in  the  mechanism  and  treatment  of  labor  pointed  out. 

Rupture  of  the  pelvic  joints  during  lal^or,  while  rare,  is  not  so  uncommon  as  is 
generally  believed.  I  have  treated  8  cases  and  have  learned  of  3  others.  In  1898 
I  published  2  cases;   in  1901,  2  more,  and  gave  the  literature  to  date  (Kayser). 

Rupture  of  the  symphysis  pubis  is  most  often  found,  but  sometimes  the  sacro- 
iUac  joints  are  involved,  either  alone  or  with  the  former.  Traumatism  causes  rup- 
ture of  the  joint,  but  since  it  requires  the  enormous  force  of  from  400  to  2600  pounds 
to  disrupt  the  pelvic  girdle,  some  inherent  weakness  of  the  joint  must  preexist. 
Softening  and  relaxation  of  the  capsules,  caries,  rachitis,  osteomalacia,  chronic 
rheumatism,  trauma  during  pregnancy,  congenital  weakness  of  the  ligaments,  have 
all  l)een  found  in  such  cases  when  even  the  distention  of  the  peh'is  during  sponta- 
neouslabor  may  cause  the  jointto  give  yvay.  Contracted  pelvis,  especially  the  justo- 
minor  and  funnel  varieties,  predispose,  because  the  expansile  force  acts  in  the 
narrow  transverse  diameter.  A  large  child  or  especiall}'  broad  shoulders  may  act 
in  the  same  way.  In  three-fourths  of  the  cases  the  joint  is  sjirung  during  operative 
delivery,  and  in  my  collection  the  forceps  caused  67  jier  cent.,  and  the  others,  the 
after-coming  head,  the  shoulders,  and  the  vectis  (Boddaert).  In  one  case  the 
rupture  occurred  postpartum  while  the  woman  got  out  of  bed,  but  probably  the 
separation  had  been  started  by  the  delivery  and  was  thus  completed.  Improperly 
directed  forceps  traction,  as  by  pulling  upward  too  soon  or  by  pulling  upward  with 
the  patient  on  a  low  bed,  in  both  cases  the  head  acting  as  a  wedge  between  the  rami. 


766  THE    PATHOLOGY    OF    LABOR 

or  using  too  great  force,  will  produce  the  ru])ture,  j^erhaps  even  in  the  absence  of 
pathologic  softening.     These  facts  are  important  from  a  medicolegal  point  of  view. 

Symptoms. — The  iiatient  may  have  complained  of  pains  in  the  pubis  and  sacro- 
iliac joints,  with  difficulty  of  locomotion  for  several  weeks.  During  spontaneous 
labor  the  rupture  may  be  discovered  at  the  moment  it  occurs,  being  heard  as  a  dull 
cracking,  or  the  Avoman  says  something  has  burst.  Usually  the  operator  feels  and 
hears  the  joint  open  during  the  operative  deliver}',  and  notes  that  the  obstruction  to 
the  progress  of  the  child  has  suddenly  disappeared.  Later  the  patient  complains 
of  intense  pain  over  the  affected  joint  and  radiating  down  the  thighs,  and  cannot 
move  the  legs,  which  lie  everted  and  abducted.  It  is  a  sort  of  pseudoparalysis,  and 
doubtless  has  often  been  mistaken  for  acute  paraplegia  due  to  injury  of  the  nerves  in 
the  pelvis  or  an  acute  infectious  myelitis.  Overstretching  of  the  joints  without 
actual  rupture  sometimes  occurs  in  difficult  forcej^s  cases,  and  makes  the  woman 
bedridden  for  months.  Bladder  and  rectal  symptoms  are  absent  unless  the  viscera 
are  injured  at  the  same  time,  which  is  not  rare. 

When  spontaneous  cure  results,  fibrous  union  takes  place  between  the  ends  of 
the  bones,  but  excessive  play  at  the  joint  may  render  the  patient  invalid  for  j-ears. 
In  general  the  results  correspond  with  those  after  symphysiotomy.  If  the  vagina 
communicates  with  the  wound,  supj^uration  is  the  rule.  Sometimes  infection  of 
the  joint  occurs  through  the  blood  or  by  contiguity,  especially  if  infection  of  the 
parturient  canal  exists.  In  pubic  arthritis  complicating  general  sepsis  it  is  hard  to 
decide  if  the  joint  was  primarily  or  secondarily  involved.  Chills  and  high  fever 
betoken  the  advent  of  infection  to  the  joint;  pus  forms  rapidly,  burrows  far,  and 
makes  a  big  abscess  unless  evacuated  early,  and  may  even  cause  fatal  pyemia. 

The  diagnosis  is  usually  easy  if  the  condition  is  at  all  considered.  The  history 
of  difficult  delivery,  the  position  of  the  patient  in  bed,  the  pain  and  tenderness  of  the 
pul)is,  the  palpation  of  a  groove  over  the  joint,  with  movability  of  the  pubes  on  each 
other,  enable  one  to  make  the  diagnosis  on  the  direct  examination.  In  the  differen- 
tial diagnosis  paraplegia  must  first  be  excluded,  which  is  done  by  finding  the  reflexes 
normal,  the  individual  muscle  groups  functionating,  and  normal  sensation. 

Later,  after  fever  has  developed,  in  their  order  must  be  considered  acute  sepsis, 
pelvic  inflammations  and  pressure  on  the  nerves  by  the  pelvic  exudates,  acute  toxic 
neuritis,  myelitis,  cystitis,  or  even  only  full  bladder  and  hysteria.  When  an  abscess 
has  formed  around  the  joint,  one  must  determine  if  the  suppuration  is  primary  or 
secondary — that  is,  part  of  a  general  infection,  the  latter  mainly  for  the  prognosis. 
Even  recognized  early,  this  accident  is  very  dangerous,  although  often  recovery  and 
later  restoration  of  function  occurs,  the  latter  requiring  from  three  to  eight  weeks, 
like  symphysiotomy.  Injuries  to  adjacent  viscera,  primary  hemorrhage,  shock,  and 
later  sepsis,  bring  the  mortahty  of  reported  cases  up  to  35  per  cent.  Infection  of 
the  joint  is  serious,  and  very  serious  if  more  than  one  is  involved,  because  the  ab- 
scesses burrow  far  and  wide.  Permanent  wide  separation  of  the  ends  of  the  pubis 
may  require  a  bone  operation,  wiring  or  nailing,  to  restore  function.  The  treatment 
is  the  same  as  after  symphysiotomy  (q.  v.). 

Loosening  of  the  sacrum  from  the  innominates  may  result  from  labor,  and, 
without  doubt,  explains  many  of  the  cases  of  backache  after  normal  as  well  as 
operative  delivery.  Pain  and  tenderness  over  the  joints,  abnormal  mobility,  the 
two  latter  determinable  best  l)y  intrapelvic  exploration,  the  pelvic  organs  being 
free  of  disease,  will  make  the  diagnosis.     The  treatment  is  along  orthopedic  lines. 

Injury  to  the  Coccjrx. — During  delivery  the  coccyx  is  forced  backward  an  inch 
or  more,  this  excursion  of  the  bone  being  permitted  by  a  healthy  sacrococcygeal 
joint.  If  the  joint  is  ankylotic,  the  bone  itself  may  be  fractured,  or  the  joint  may 
break  open,  a  chronic  arthritis  resulting.  Dislocations  of  the  bone  onto  the  an- 
terior or  posterior  surface  of  the  sacrum  occur,  and  also  a  pericoccygeal  cellulitis, 
which  is  chronic  and  very  painful.     Without  dou])t  many,  if  not  most,  of  the  cases 


INJURIES    TO    THE    BLADDER,    RECTUM,    ETC.

of  so-called  coccygodynia  are  referaljle  to  the  al)Ove  conditions.  After  injury  to 
the  bone  the  ends  may  unite  at  a  right  angle,  or  such  deforniit.y  may  occur  at  the 
joint,  though  oftener,  because  the  bone  is  moved  so  frequently  (walking,  defecation, 
sitting),  a  pseudarthrosis  is  formed. 

Even  while  the  woman  is  in  bed  there  are  sjTnptoms  referable  to  the  injur}',  as 
pain  in  defecation,  and  tenderness,  but  usually  the  first  sitting-up  attracts  the  at- 
tention of  the  accoucheur.  Inability  to  sit  with  comfort,  the  patient  often  resting 
her  body  on  either  trochanter,  pain  radiating  up  the  back  and  do\\Ti  the  thighs, 
difficulty  of  locomotion  because  of  pain,  painful  defecation,  and  intense  nervous- 
ness— often  a  real  neurasthenia — are  the  main  symptoms.  The  diagnosis  is  easy, 
since  the  history  will  draw  attention  to  the  location  of  the  trouble,  and  an  exami- 
nation with  the  finger  in  the  rectum  and  the  thumb  over  the  coccyx  will  show 
dislocation  of  the  bone,  fracture  (crepitus),  or  excessive  tenderness  in  or  around  the 
joints  (Fig.  704). 

Spontaneous  recover^'  is  the  rule,  but  sometimes  it  requires  many  months.

Treniment-  Local  applications  <iive  very  little  relief.  In  cases  of  cellulitis  a  gentle  massage, 
after  tlie  acuteness  has  subsidcnl,  will  help.  For  fracture  and  dislocations  a  period  of  at  least  six 
months  should  be  allowed  for  spontaneous  cure,  and  then,  in  the  absence  of  improvement,  the  bone 
is  to  Ik'  exci.sed.  For  three  days  before  the  operation  the  bowels  are  to  be  kept  free,  then  bound 
up  with  bismuth  and  a  few  doses  of  opium,  as  before  operations  for  fistulas.  Sim's  position  is  used. 
A  two-inch  vertical  incision  is  made  over  the  joint,  and  the  firm  fibrous  tissue  is  cut  down  to  the 
bone.  This  is  bared  and  lifted  up  with  a  bullet  forceps.  With  a  sharp  knife  it  is  detached  from 
the  coccygeus  on  each  side  and  the  lower  fibers  of  the  sacrosciatic  ligament,  taking  care  to  avoid 
tearing  the  fascia  on  its  anterior  surface.  The  joint  is  severed  last,  or,  if  the  fracture  had  not  united, 
the  distal  portion  of  the  bone  is  excised  and  the  proximal  portion  smoothed  with  the  bone  forceps. 
The  whole  coccyx  had  best  be  removed.  The  rectum  is  attached  to  the  end  of  the  sacrum  by  a 
few  firm  strands  of  connecti\-e  tissue;  care  is  required  to  prevent  tearing  this  organ.  Hemorrhage 
is  stopped  by  packing  with  hot  iodoform  gauze  for  a  few  minutes.  Then  the  two  edges  of  the 
coccygeus  muscle  are  united  in  the  median  line  by  interrupted  catgut  sutures;  next  the  fascia 
which  was  over  the  bone  and  three  or  four  deep  silkworm-gut  sutures  close  the  skin.  Accurate 
coaptation  of  the  edges  of  the  skin  should  be  obtained,  and  the  wound  jiainted  with  collodion. 
The  patient  should  keep  the  side  position  for  three  days.  On  the  fifth  day  castor  oil  is  given.  It 
is  highly  important  that  feces  and  urine  do  not  contaminate  the  wound,  and  the  patient  should  sit 
up  straiglit  or  bend  forward  when  the  bowels  move. 

Other  Injuries. — As  the  result  of  overpo\\ (>rf ul  bearing-down  efforts  the  woman  may  fracture 
her  sternum  or  dislocate  one  or  more  ribs  ujion  it.  The  severe  straining  may  rupture  the  vesicles 
of  the  lung  and  give  rise  to  emphj'sema  of  the  neck,  chest,  e\en  of  the  entire  body.  Kosmak,  in 
1907,  collected  77  cases  in  the  literature  since  1791.  Primipanr  are  usually  affected.  Tenderness 
and  dyspnea  are  prominent ;  the  prognosis  is  good,  the  swelling  disappearing  in  a  few  days  without 
treatment.

CHAPTER  LXI 
POSTPARTUM  HEMORRHAGE 

Strictly  speaking,  postpartum  hemorrhage  means  l^lceding  after  labor,  that 
is,  after  the  placenta  is  delivered,  but  for  purpose  of  study  it  is  best  to  consider  under 
this  heading  all  hemorrhages  occurring  from  the  time  the  child  is  delivered  until 
the  puerperium  is  completed.  Those  which  occur  after  the  first  twenty-four  hours 
are  called  late  hemorrhages,  and  will  be  considered  separately.  At  present  we  are 
concerned  only  with  those  attending  the  delivery  of  the  placenta  and  immediately 
thereafter. 

The  reproductive  function  is  the  only  one  normally  attended  by  hemorrhage, 
and  nature,  by  wise  provision,  fortifies  the  woman  against  the  inevitable  loss,  and 
even  overprovides,  so  that  she  may  survive  a  drain  that  would  prove  fatal  in  a  non- 
pregnant female  or  a  male.  During  pregnancy  the  total  quantity  of  blood  is  in- 
creased, and  the  fibrin  is  also  greater  in  amount,  these  changes  beginning  after  the 
fifth  month.  There  is  a  slight  leukocytosis  which  becomes  marked  (16,000)  during 
labor.  In  healthy  gravidae  these  are  the  changes,  while  in  a  sickly  or  anemic  woman, 
pregnancy  may  induce  a  condition  of  chloranemia.  The  point  has  a  strong  clinical 
bearing. 

In  health}^  gravidae  a  loss  of  blood  up  to  one  pint  (500  gm.)  is  usually  borne 
without  any  symptoms,  and  it  is  generally  believed  that  the  woman  has  gained  about 
this  amount  during  pregnancy.  The  average  loss  during  labor  is  about  300  gm. — 8 
to  10  ounces.  It  is  best  to  consider  a  loss  above  a  pint  as  pathologic.  Bloodless 
labors  are  very  rare,  and  are  usually  found  where  the  fetus  has  been  dead  a  long  time 
and  firm  thrombosis  has  occurred  in  the  placental  site.  Leukemics  also  are  said  to 
have  bloodless  labors,  which  is  fortunate,  if  generally  true,  because  leukemics 
stand  bleeding  badly.  Before  the  expulsion  of  the  placenta  the  oozing  should 
be  very  slight,  if  any,  and  after  it  the  puerpera  should  not  lose  over  3  ounces  of 
fresh  blood  in  the  first  two  hours.  Inclosed  in  the  placenta  will  be  found  the  bulk 
of  the  blood.  If  the  blood  gushes  from  the  genitals  or  oozes  steadily  in  larger 
amounts  than  here  indicated,  the  case  is  pathologic. 

ETIOLOGY 

During  the  separation  and  expulsion  of  the  placenta  hemorrhage  is  prevented 
by  the  retraction  and  contraction  of  the  uterine  muscle  and  by  thrombosis  of  the 
uterine  sinuses.  The  more  important  factor  in  securing  hemostasis  is  the  uterine 
action,  since  thrombosis  may  be  absent  and  no  hemorrhage  occur;  and,  conversely, 
thrombosis  alone,  unaided  by  the  contraction  and  retraction  of  the  uterus,  Avill  not 
check  a  hemorrhage. 

The  sinuses  in  the  uterine  wall  are  simply  blood-spaces,  lying  between  the  mus- 
cular lamellae  and  muscle-bundles,  and  lined  with  a  single  layer  of  endothelium. 
As  the  uterus  empties  the  muscular  lamellae  become  superimposed,  the  muscle- 
bundles  crowd  closer  together,  thesevcral  layerssliding  over  each  other.  As  a  result, 
the  blood  sinuses  are  bent  and  twisted  on  themselves,  the  mus(;le  effectually  choking 
off  the  current  of  blood  that  flowed  through  them.  There  is  even  some  influence  on 
the  larger  vessels  at  the  sides  of  the  uterus  after  they  enter  its  wall.  The  retraction 
of  the  uterine  muscle  does  the  actual  work  in  this  operation.  The  regularly  re- 
curring uterine  contractions  aid  and  support  the  permanent  retraction.

POSTPARTUM   HEMORRHAGE 


769 


Postpartum  liemorrhage,  therefore,  will  be  most  often  found  to  be  due  to  some 
anomaly  of  this  physiologic  mechanism,  and  such  anomalies  are  usually  due  to 
weakness  or  abnormal  contraction  and  retraction  of  the  uterus.  In  practice  we 
find  two  additional  factors — lacerations  of  the  parturient  canal  and  disease  of  the 
blood  or  blood-vessels. 

(A)  Lacerations  of  the  genital  tract  play  a  nuich  more  important  role  in  the 
production  of  hemorrhage  postpartum  than  is  generally  believed.  ]\Iany  hemor- 
rhages called  atonic  are  due  to  tears  in  the  genitalia. 

Lacerations  of  the  clitoris  and  of  the  bulbi  may  give  rise  to  even  fatal  hemor- 
rhage, as  may  also  a  ruptured  varix  of  the  vulva  or  vagina,  though  both  are  rare. 
Perineal  tears  seldom  bleed  enough  to  require  immediate  suture,  and  vaginal  tears

are  also  rarely  attended  l)y  much  hemorrhage.  They  may,  however,  recjuire  suture 
or  packing,  and  when  they  do,  packing  is  the  best  method,  because  the  field  is  so 
inundated  with  blood  that  it  is  impossible  to  see  where  to  place  the  sutures. 
High  vaginal  tears,  extending  into  the  fornices,  may  lay  open  the  bases  of  the 
broad  ligaments  and  may  bleed  furiously.  They  are  usually  combined  with 
cervix  tears. 

A  laceration  of  the  cervix  extending  into  the  broad  ligament  may  not  bleed  if 
the  tearing  is  gradual  and  not  forced,  Such  findings  are  occasionally  made  after 
spontaneous  labors  or  dilatation  with  one  of  the  crushing  dilators  (the  Bossi,  dc 
Seigneux)  or  the  hands  (Bonnaire,  Harris).  Usually,  however,  a  deep  cervical  tear 
gives  rise  to  serious  hemorrhage.  Deep  cervical  tears  are  most  likely  to  occur  if  a 
rapid  delivery  is  made  before  the  cervix  is  completely  effaced  or  shortened,  that  is,

drawn  up  into  tlio  ])o{ly  of  the  uterus.  Even  after  tlie  cervix  is  completely  dilated 
a  laceration  of  the  upper  fibcM-s  may  result  if  the  extraction  of  the  child  is  forced 
during  a  spasmodic  contraction  of  the  lower  uterus  and  ujijx'r  cervix.  Sometimes 
the  head  passes  through  tlie  cervix  and  the  contraction  ring  closes  down  around  the 
neck  of  the  child.  Forcing  the  deliver^'  in  such  a  case  may  cause  the  shoulders  to 
tear  the  edge  of  the  contraction  ring.  In  the  last  three  varieties  of  cervical  lacera- 
tion the  tear  is  more  likely  to  be  a  longitudinal  split  of  the  cervical  wall,  usually 
lateral,  extending  more  or  less  deeply  into  the  broad  ligament,  and  indicating  that 
if  it  went  much  further  it  would  have  to  be  called  a  rupture  of  the  uterus,  incomplete 
ot  complete,  depending  on  whether  or  not  the  peritoneal  cavity  was  opened.  With- 
out doubt  many  cases  of  so-called  postpartum  hemorrhage  are  in  reality  ruptures  of 
the  uterus,  as  likewise  are  many  cases  of  "shock"  after  lalior.  A  rupture  of  the 
uterus  occurring  during  an  operation  or  spontaneously  gives  rise  to  internal  and 
external  hemorrhage,  and  such  cases  are  not  to  be  considered  in  this  chapter. 

When  the  cervix  is  torn  after  complete  effacement,  but  before  complete  dilata- 
tion, few  large  blood-vessels  are  opened  unless  the  tear  extends  into  the  bases  of  the 
broad  ligament. 

Special  emphasis  must  be  placed  on  the  lacerations  of  the  cervix  and  lower 
uterine  segment  occurring  in  placenta  prsevia.  It  is  usually  thought  that  the  fre- 
quency of  postpartum  hemorrhage  in  placenta  prcevia  cases  is  due  to  uterine  atony, 
while  as  a  matter  of  fact  atony  is  rare,  there  being  often  too  strong  uterine  action. 
The  branches  of  the  uterine  artery  supplying  the  lower  uterine  segment  are  given 
off  above  the  contraction  ring,  and  therefore,  are  somewhat  compressed  by 
the  contracting  uterus  before  entering  the  relaxed  lower  uterine  segment. 
While  one  would  expect  a  placental  site,  located  out  of  the  active  contracting  zone, 
to  permit  free  oozing,  this  is,  to  a  large  extent,  prevented  by  the  peculiar  situation  of 
the  blood-supply.  Hemorrhage,  therefore,  is  due  to  some  other  cause,  and  this 
will  usually  be  found  to  be  a  laceration.  The  extreme  vascularization  of  the  lower 
uterine  segment  and  cervix,  due  to  the  placental  implantation,  permits  every  tear 
to  bleed  profusely.  Since  the  veins  and  sinuses  are  situated  close  to  the  surface,  a 
laceration  one-eighth  inch  deep  may  cause  uncontrollable  hemorrhage  and  may  be 
discovered  only  at  the  autopsy. 

(B)  Insufficient  retraction  and  contraction  of  the  uterus,  or  anomalies  of  the 
same,  cause  few  of  the  fatal  postpartum  hemorrhages.  Thej'  may  be  associated 
with  any  of  the  lacerations  previously  described,  and  when  the  tear  is  situated  in  the 
lower  uterine  segment,  the  absence  of  a  firm  restraining  action  of  the  uterus  is 
apparent. 

It  is  not  feasible  to  try  to  separate  anomalies  of  retraction  from  those  of  con- 
traction. Normally,  the  two  functions  cooperate,  and  in  practice  we  find  that  where 
the  uterus  does  not  contract  well,  it  does  not  retract  well.  We  will  call  a  uterus 
atonic  when  the  contraction  and  retraction  of  its  muscles  are  insufficient  or  irregular, 
though  etiologically  and  strictly  other  terms  should  be  used.  ''Uterine  atony" 
is  a  favorite  term  for  these  conditions,  but  it  does  not  always  apply  to  the  case. 

The  causes  of  atonic  hemorrhages  are  general  and  local.  Generally  weak 
women — those  of  excessive  (cultivation,  who  often  have  poorly  develoi)ed  genitalia 
and  generally  poor  innervation — have  slow  labors  and  a  greater  tendency  to  atony 
in  the  third  stage.  Exhaustion  from  prolonged  labor,  especially  if  the  parturient 
takes  no  food,  may  lead  to  atony.  In  some  families  a  tendency  to  postpartum 
hemorrhage  is  transmitted.  This  is  an  entirely  different  condition  from  hemophilia, 
Avhich  is  to  be  considered  later.  Some  women  liave  atony  of  the  uterus  in  successive 
labors.  This  may  l:>e  due  to  a  persistence  of  a  local  cause.  Blonds  and  red-haired 
women,  in  the  author's  experience,  are  likely  to  have  hemorrhage  postpartum,  but 
how  much  is  dependent  on  the  constitution  of  the  blood  it  is  impossible  xo  say.  Myo- 
carditis, valvular  disease,  and  pulmonary  affections  are  said  to  favor  atonia  uteri,

but  the  writer  has  had  Httlo  trouble  with  it  in  such  cases.     Chronic  nephritis  has 
been  given  as  a  cause  of  atony,  a  hyahne  degeneration  of  the  uterine  muscle  and 
disease    of    the    blood-vessels    being    directly 
active. 

The  use  of  chloroform  during  labor  un- 
doubtedly increases  the  tendency  to  hemor- 
rhage, though  this  action  is  not  constant. 

Of  local  causes  there  are  many:  Overdis- 
tention  of  the  uterus  by  twins — poh'hydram- 
nion;  a  large  or  diseased  fetus,  or  an  accumu- 
lation of  blood  (abrui)tio  placentie).  The  elon- 
gated muscle-fibers  need  time  to  accommodate 
themselves  to  the  rapidly  diminishing  uterine 
cavity,  so  that  sudden  emptying  of  such  a  dis- 
tended uterus  nearly  always  predisposes  to 
hemorrhage.  Abnormal  shape  of  the  uterus, 
bihorned  uteri,  uterus  arcuatus,  septus,  etc.; 
distortion  of  the  uterus  by  adhesions  (rarelj^ ; 
distortion  by  tumors,  as  fibroids  (conmionly); 
old  scars  in  the  uterus,  after  cesarean  section, 
or  ruptures — all  these  interfere  with  the  con- 
traction and  retraction  of  the  organ  and  alloAV 
the  sinuses  to  remain  open,  and  from  these 
more  or  less  i)rofuse  hemorrhage  occurs. 

Metritis  is  given  by  J.  \v\{  as  a  cause  of 
atony.     Lal)hardt  found  an  anatomic  basis  for 

such  hemorrhages  in  an  increase  of  the  uterine  fibrous  tissue  around  the  blood- 
vessels.    This  may  have    preexisted  or    have  developed  during  pregnane^',  and

explains  the  frequency  of  heniorrliage  in  old  multipara^,  in  cases  of  suI)inv()lution, 
and  after  puerperal  infection. 

Endometritis  is  a  cause,  since  retention  of  pieces  or  all  the  placenta  is  favored. 
A  piece  of  placenta,  a  placenta  succenturiata,  or  what  acts  the  same  way,  a  thick 
layer  of  decidua  with  clots  deposited  on  it,  prevents  proper  retraction  of  the  uterus 
and  the  latter  fills  with  blood.  Abnormal  adherence  of  the  jilacenta  to  the  uterine 
wall,  with  partial  separation, — "placenta  accreta"  (Fig.  706), — causes  the  worst 
hemorrhages.  In  such  cases  the  villi  burrow  into  the  uterine  muscle — there  is  no 
decidua  serotina.  Retained  membranes,  sometimes  mixed  with  a  clot,  or  a  large 
hard  clot  itself,  may  act  like  pieces  of  placenta.  They  cause  persistent  oozing  after 
labor,  which  may  l)e  enough  to  demand  interference.  If  the  primary  hemorrhage 
ceases,  the  foreign  body  may  dissolve  and  come  away  in  the  lochia,  wliich  are  profuse

and  fetid,  or  it  may  be  discharged  en  masse,  more  or  less  decomposed,  or  there  may 
be  repeated  hemorrhages  which  require  interference,  or  a  placental  polyp  forms. 
Tubal  corner  placenta3  (Fig.  707)  separate  poorly  because  of  the  bad  uterine  action. 
Atony  of  the  placental  site  (Fig.  708)  is  more  frequent  than  is  generally  thought.  It 
may  be  the  beginning  of  inversion. 

Irregular  acticm  of  the  uterus  itself,  the  formation  of  contraction  rings  (see  p. 
574,  Strictura  Uteri),  the  best  known  of  which  is  the  "hour-glass  contraction" 
(Fig.  709),  an  exhausted  uterus,  one  displaced  by  a  full  bladder  or  rectum — all  these 
maj'  be  attended  by  bleeding.     The  full  bladder  as  a  cause  must  be  emphasized. 

Improper  conduct  of  laljor,  too  rapid  delivery  of  the  child,  which  is  dragged  out 
of  the  uterus  without  allowing  time  for  the  latter  to  adapt  its  walls  to  its  diminishing 
contents;  too  much  massage  of  the  fundus  in  the  third  stage,  with  premature 
attempts  to  expel  the  placenta  by  Crede  expression,  traction  on  the  cord,  giving 


POSTPARTUM    HEMORRHAGE  773 

ergot  too  soon — all  these  disturb  the  normal  mechanism  of  the  third  stage  by  pro- 
ducing anomalous  uterine  action,  breaking  the  retroplacental  hematoma,  separat- 
ing the  placenta  partially,  bruising  the  uterus,  and  crushing  the  placenta,  which 
favors  retention  of  jiieces  of  it,  and  all  cause  bleeding. 

(C)  Abnormal  blood  .states  or  diseases  of  the  blood-vessels  may  cause  severe  and 
even  fatal  postpartum  hemorrhage.  Hemophilia  is  rare,  and  while  it  usually 
causes  severe  hemorrhage,  death  seldom  results.  Ahlfeld  reported  a  fatal  case; 
the  author  has  had  two  fatal,  and  two  other  severe,  hemophilic  bleedings;  Wells 
reports  one.  Scurvy,  Werlhoff's  disease,  syphilis,  certain  <'hronic  anemias  and 
to.xemias,  and  sepsis  maj^  all  lead  to  profuse  hemorrhages.  Without  doubt  such 
hemophilic  tendencies  may  develop  during  pregnancy.  They  may  be  of  a  toxemic 
nature.  Lack  of  thrombokinase  explains  the  actual  bleeding,  but  it  may  not  be 
possil)le  to  explain  the  absence  of  the  ferment. 

SYMPTOMS 

General. — The  symptoms  are  those  of  loss  of  blood,  and  vary  in  intensit}'  with 
the  rapicUty  of  the  flow,  the  amount,  the  condition  of  the  patient,  and  idiosyncrasy. 
A  sudden  large  loss  is  attended  by  shock,  which,  being  overcome,  the  patient  rapidly 
improves.  A  slow  but  long-continued  hemorrhage  is  more  often  fatal.  Previous 
repeated  hemorrhages,  as  from  placenta  prsevia,  exhaust  the  blood-making  organs, 
so  that  even  a  small  loss  in  labor  is  badly  borne.  Chloranemics,  leukemics,  sufferers 
from  malarial  and  certain  cachexias,  diabetics,  and  tj'phoids  are  bad  subjects. 

The  s\Tnptoms  of  hemorrhage  in  the  usual  order  of  their  appearance  are: 
Faintness,  dizziness,  air-hunger,  ya^ATiing,  nausea,  restlessness,  thirst,  precordial 
anxiety,  smothering  fear  of  impending  dissolution,  vomiting,  fainting,  collapse, 
convulsive  t^^'itchings,  and,  as  death  nears,  involuntary  bowel  movements  and 
coma.  These  sjinptoms  in  a  person  already  anemic  come  on  sooner  and  more 
pronouncedly.  Examination  will  show  the  face  pallid,  the  lips  bluish  white,  the 
nose  and  forehead  cold,  and  sometimes  covered  with  sweat,  the  eyes  sunken,  the 
conjunctivae  pearly,  respiration  rapid  and  shallow,  the  pulse  small  and  fast,  filiform, 
and  finally  gone  from  the  wrist.  Sometimes  the  pulse  holds  up  well  for  a  Avhile, 
then  suddenly  disappears.  These  cases  give  a  false  sense  of  security,  because  the 
pulse  is  slow.  By  determining  the  fullness  of  the  vessel  an  error  of  judgment  may 
be  avoided. 

It  is  astonishing  how  much  blood  a  woman  can  lose  and  surx-ive.  Ahlfeld  confined  several 
thousand  women  on  a  bed  with  a  hole  through  the  center,  underneath  which  was  placed  a  glass 
graduated  pail.  He  found  that  in  a  normal  labor  the  loss  of  blood  would  average  435  c.c;  that 
pathologic  labors  show  an  average  of  677  c.c,  the  average  blood-loss  of  all  labors  being  505  c.c. 
Ahlfeld,  therefore,  concludes  that  a  loss  up  to  800  c.c.  is  normal,  and  that  a  healthy  woman  of 
average  weight  may  safely  lose  a  liter,  which  is  a  little  more  than  a  quart.  Ahlfeld  found  that  the 
first  symptoms  following  loss  of  one  liter  were  pallor  and  rapid  pulse;  as  the  flow  continued  up  to 
1600  or  ISOO  c.c,  the  surface  of  the  patient  grew  cold,  sweat  appeared,  and  thirst,  dyspnea,  yawn- 
ing, dizziness,  and  faintness  were  to  be  noted.  Occasionally,  death  occurred  irilh  a  loss  of  less  than 
tu-o  liters.  In  6000  labors  there  were  14  hemorrhages  over  2.500  c.c.  (5  pints),  one  of  which  was 
over  .3000  c.c.  All  the  patients  recovered.  A  loss  of  3S00  to  4000  c.c.  (a  gallon)  is  considered 
absolutely  fatal.  No  doubt  the  danger  to  life  of  severe  blood-loss  postpartum  appears  greater 
than  it  really  is,  but  since  one  cannot  predict  the  woman's  ability  to  withstand  bleeding,  it  is 
prudent  to  take  alarm  at  small  hemorrhages  and  quickly  institute  means  to  check  them.  Ahlfeld's 
cases  were  hard}-  peasant  women.  Our  highly  bred  American  women  would  show  more  serious 
results  and  many  would  die  from  such  extreme  lo.s.ses  of  blood. 

Local. — The  bleeding  may  be  internal  or  external  or  both.  If  the  cer%'ix  is 
occluded  by  a  clot,  membranes,  or  the  placenta,  or  if  the  \'ulva  is  held  closed  bj'  ap- 
position of  the  thighs,  an  enormous  amount  of  blood  may  be  dammed  back,  cUstending 
the  vagina  and  the  uterus.  When  the  hand  is  borne  on  the  belly  or  the  uterus,  blood 
gushes  out.  Sometimes  there  is  a  terrific  rush  of  blood  following  the  child,  and  it 
may  be  fatal  in  a  few  minutes.  Only  a  man  who  has  seen  one  would  believe  such  a 
flooding  could  occur.     Usually  there  is  a  steady  oozing  or  more  copious  flow,  neces-

THE    PATHOLOGY    OF   LABOR 


sitating  frequent  changing  of  the  sheets.  A  wise  aecoucheur  will  make  note  of  the 
number  of  changes.  Sometimes  the  flow  is  interrupted,  the  uterus  filling  and  empty- 
ing several  times,  or  there  may  be  one  gush  and  that  be  all,  the  uterus  having  ob- 
tained a  firm  grasp  of  itself.  The  first  blood  is  thick  and  deep  red;  later  it  grows 
paler,  and  it  appears  to  mc  it  has  lost  its  clotting  power.  Sometimes  the  Ijlood  is 
dark,  like  port  wine,  and  the  clots  are  black,  or  it  seems  to  be  lake-colored — trans- 
lucent;  this  an  evidence  of  hemolysis. 

The  local  findings  vary  with  the  cause  of  the  hemorrhage.  If  from  laceration, 
the  uterus  is  usually  hard,  but  sometimes  it  fills  up  with  blood  and  becomes  atonic. 
In  real  atonia  uteri  it  is  difficult  to  locate  the  flabby  fundus;  the  whole  abdomen 
feels  boggy.  If  the  placenta  is  incarcerated,  the  uterus  is  firm  and  glol>ular,  but 
balloons  out  between  pains,  and  each  contraction  is  attended  by  a  gush  of  blood  from 
the  vagina  (Fig.  709). 

DIAGNOSIS 

Ideal  obstetrics  demands  that  no  woman  should  lose  enough  blood  to  give  rise 
to  symptoms  of  anemia.  If  such  are  present,  the  accoucheur  must  quickly  deter- 
mine their  cause,  and  shock,  rupture  of  the 
uterus,  inversion,  rupture  of  an  abdominal  vis- 
cus,  pulmonary  embolism,  and  uremic  collapse 
are  to  be  considered.  When  the  amount  of 
l)lood  known  to  have  been  lost  is  small  and  the 
uterus  is  well  contracted,  probably  some  other 
cause  is  acting,  but  the  idiosyncrasy  of  the 
patient  must  be  remembered.  Almost  always 
the  question  to  decide  is  the  source  of  the 
bleeding.  Broadly  speaking,  a  bleeding  with 
a  hard  uterus  comes  from  laceration,  and  when 
the  organ  is  large,  boggy,  or  even  too  soft  to 
outline,  atony  is  the  cause.  The  history  of  the 
labor  will  give  valuable  data;  if  the  uterine  ac- 
tion was  torpid  in  the  first  two  stages,  inertia 
may  be  expected  in  the  third.  (See  Etiology.) 
After  forceps  or  other  operations,  lacera- 
tions are  to  be  looked  for,  and  they  will  be  found 
in  the  operative  field.  Before  the  placenta  is 
out  it  may  be  impossible  to  decide  between 
atony  and  injury.  As  a  rule,  diagnosis  and 
treatment  go  together,  and  this  is  the  usual 
procedure :  A  brisk  massage  is  given  the  uterus, 
and  at  the  same  time  the  vulva  and  introitus 
are  sponged  free  of  blood  and  inspected  carefully  for  tears.  If  firm  contrac- 
tion of  the  uterus  ensues,  the  hemorrhage  ceasing,  atony  was  i)robably  the 
cause,  and  nothing  further  is  done.  If  not,  the  placenta  is  removed.  Now 
if  the  bleeding  continues  with  a  hard  uterus,  laceration  is  probably  the  cause. 
A  vaginal  examination  will  settle  the  doubt.  Venosity  of  the  blood  is  no  criter- 
ion of  atony.  Concealed  hemorrhage  may  be  due  to  a  tear  as  well  as  atony, 
and  the  blood  may  not  appear  for  from  five  to  fifteen  minutes  after  delivery.  It 
is  ofttimes  necessary  to  decide  whether  or  not  a  piece  of  placenta  or  a  clot  is  still 
in  the  uterus.  In  the  first  place,  a  careful  inspection  of  the  placenta  should  invari- 
ably be  made  imrnediately  after  its  delivery,  while  it  and  the  accoucheur's  hands 
are  still  aseptic,  because  it  may  be  necessary  to  at  once  enter  the  uterus.  If  the 
placenta  is  too  much  torn  to  guarantee  certainty  that  nothing  has  ])(>en  retained, 
and  bleeding  continues,  it  is  best  to  revise  the  uterus  with  the  hand.     A  large

elastic,  globular  uterus,  issuing  occasional  gushes  of  blood,  almost  always  has 
something  inside  it.  If  a  clot  is  seen  or  felt  in  the  vagina,  probably  another  lies 
in  the  uterine  cavity.  If  the  attendant  notes  the  discharge  of  ])lood-serum  from  the 
vagina,  he  may  be  sure  that  there  is  a  clot  in  the  parturient  canal. 

Incarceration  of  the  placenta  is  diagnosed  from — (1)  The  large  globular  uterus, 
whose  contractions  are  irregular  as  to  time,  strength,  and  location;  (2)  the  inter- 
mittent gushes  of  l)lood;  (3)  the  cord  advances  and  recedes  when  pressure  is  made  on 
the  functus;  (4)  the  vein  in  the  umbilical  cord  becomes  tense  when  the  uterus  is 
compressed;  (5)  internal  examination  discloses  the  tight  contraction  ring  with  the 
placenta  above  (Fig.  709). 

PROGNOSIS 

Nowadays  few  women  die  from  postpartum  hemorrhage.  In  over  15,000  con- 
secutive cases  in  the  Chicago  Lying-in  Hospital  Dispensary  service  not  one  woman 
died  from  it,  but  there  were  six  or  more  who  came  very  near  death.  Statistics  are 
hard  to  get.  In  the  United  States  about  750  deaths  from  puerperal  hemorrhage  are 
annually  recorded.  Diihrssen  said  that  in  Germany  a  woman  dies  every  day  from 
postpartum  hemorrhage.  In  general,  it  may  be  said  that  severe  hemorrhage  occurs 
in  about  2  per  cent,  of  labors,  but  that  a  death  in  experienced  hands  is  rare — prob- 
ably not  oftener  than  once  in  5000  deliveries.  Cases  of  true  atony  are  rare,  and 
often  fatal,  but  not  more  often  fatal  than  cervix  tears  in  placenta  previa.  Simple 
cervix  tears  offer  a  better  prognosis  than  atony,  especially  if  the  latter  is  due  to 
disease  of  the  uterine  structure.  Tears  of  the  clitoris  and  of  varices  in  the  vagina 
may  be  fatal  unless  recognized  early. 

In  individual  cases  the  expressed  prognosis  as  to  life  will  depend  on  the  phy- 
sician's examination  and  his  estimate  of  the  proportion  of  the  woman's  blood  that 
is  lost.  The  pulse,  while  a  good  one,  is  not  always  a  reliable  guide.  I  have  felt  a 
fairly  good  slow  pulse  with  a  serious  hemorrhage.  It  seems  as  if  the  arteries  can 
keep  their  grasp  on  the  circulation  up  to  a  certain  point,  which,  being  passed,  they 
lose  their  grip  and  collapse  occurs.  The  quality  of  the  pulse-beat  gives  more  infor- 
mation than  its  rapidity.  Hurried  respiration,  extreme  dyspnea,  and  air-hunger 
are  very  ominous,  but  not  necessarily  fatal,  sjmiptoms.  Extreme  restlessness  and 
repeated  vomiting  indicate  a  very  serious  condition. 

At  the  beginning  it  is  impossible  to  foretell  how  dangerous  a  certain  bleeding 
will  become.  Slight  oozing  may  baffle  the  accoucheur  entirely,  while  a  furious 
cascade  of  blood  may  suddenly  cease.  It  is  advisable  to  stop  all  hemorrhages  as 
soon  as  possible,  because  the  constitution  of  the  patient  is  an  unknown  quantity. 

There  are  remote  dangers  in  these  cases.  Thrombosis  and  eml^olism  are  com- 
moner after  severe  losses,  and  sepsis,  too,  the  latter  because  the  resisting  power  of 
the  woman  has  been  lowered,  and,  secondly,  because  the  accoucheur,  in  his  haste, 
has  forgotten  the  princi]:)les  of  asepsis.  Hemorrhage  into  the  retina  and  edema 
with  blindness,  chronic  diarrhea,  gastric  ulcer,  and  permanent  debilitation  of  the 
blood  and  neurasthenia  have  been  noted  as  sequels.  Even  in  cases  where  the 
blood-loss  did  not  exceed  800  gm.  the  patients  made  slower  recoveries,  lactation 
was  interfered  with,  suliinvolution  was  commoner — altogether  the  convalescence 
was  not  so  satisfactory  as  in  those  women  where  the  bleeding  was  strictly  limited. 


TREATMENT 
Prevention  should  begin  during  pregnancy,  and  the  patient's  family  and  per- 
sonal history  will  l)e  the  guide.  If  such  a  history,  which  should  be  a  part  of  the 
routine  examination  when  the  accoucheur's  services  are  engaged,  should  discover 
any  of  the  causes  of  postpartum  hemorrhage  mentioned  under  Etiology,  appropriate 
treatment  during  gestation  may  prevent  trouble,  at  least,  the  warning  will  have

been  sounded  in  time  to  have  everything  in  readiness  for  instant  use  if  necessary. 
Thus  valuable  time  is  saved.  Forewarned  is  forearmed.  During  labor  the  possi- 
bilit}'  of  postpartum  hemorrhage  must  be  borne  in  mind,  particularly  when  the  ac- 
tion of  the  uterus  is  sluggish,  and  in  cases  of  overdistention,  twins,  polyhydramnion, 
etc.     By  supporting  the  parturient  with  food,  rest,  and  help  at  the  proper  time

much  can  be  done.  Too  early  operative  interference  causes  lacerations  and  hemor- 
rhage. In  delivery  the  uterus  must  be  slowly  emptied,  and  especiallj-  must  the 
rules  of  the  conduct  of  the  third  stage  be  closely  observed. 

Preparations. — Every  obstetric  kit  should  contain  the  apparatus  for  coping 
with  this  complication:  (1)  Instruments  for  the  repair  of  lacerations  (Fig.  664); 
(2)  for  douching  the  uterus,  douche-can  or  bag,  with  tube  and  nozzle;    (3)  for  packing

for  the  treatment  of  anemia,  salt  solution  apparatus,  or  a  sterile  douche-bag  or  can

follows  the  delivery  of  the  child,  the  first  move  is  to  grasp  the  uterus  and  massage

the  same  time  the  attendant  insjiects  the  genitals  to  find  the  laceration  that  may  be 
bleeding.  If  the  uterus  contracts  and  the  hemorrhage  continues,  an  internal  ex- 
amination should  be  made  to  see  if  there  is  a  cervix  tear.     Should  the  bleeding  con-

tinue,  it  is  necessary  to  remove  tlie  placenta  whether  or  not  a  tear  is  found.  Mas- 
sage the  womb  vigorously,  antl  in  the  moment  of  contraction  perform  Crede  expres- 
sion. This  mano^uver  may  stop  the  flow;  if  not,  it  will  be  needful  to  remove  the 
placenta  manually.  Before  attempting  the  Crede  one  must  empty  the  bladder  by 
catheter  and  bring  the  uterus  to  the  median  line.  Squeeze  only  when  the  organ  is 
contracting  and  hard.     It  is  useless  and  very  dangerous  to  squeeze  a  soft  uterus.

Manual  Removal  of  Placenta. — Having  decided  that  it  is  necessary  to  remove  the  pla- 
centa manually,  the  patient  is  brought  across  the  bed,  with  the  buttocks  well  over  its  edge;  the 
assistant,  either  a  physician,  a  nurse,  or,  if  absolutely  necessary,  the  husband  or  a  covu'ageous 
neighbor,  holds  the  legs  in  the  lithotomy  position,  and  the  acicoucheur  sees  that  his  instruments, 
basins  with  antiseptic  solutions,  gauze  for  packing  the  uterus,  and  a  hot  douche  are  all  prepared  and 
within  easy  reach.  If  the  accoucheur  has  his  obstetric  technic  well  developed,  and  his  assistants 
and,  most  important  of  all,  his  clientele,  properly  train(>d,  it  is  jxjssible  to  be  so  prepared  for  labor 
cases  that  a  change  from  the  bed  to  the  kitchen-table  may  be  made  in  a  minute.  I'sually,  however, 
the  exigencies  of  the  case  will  force  the  j^hysician  to  operate  with  th(>  patient  across  the  bed,  but 
whenever  it  is  possible  one  should  do  these  things  on  a  table.  This  is  one  of  the  most  dangerous 
operations  in  obstetric  practice,  because  of  the  likelihood  of  infection  of  the  naked  placental  site.

Its  mortality  is  placed  by  Bumm  at  10  per  cent.     It  is,  therefore,  best  to  make  another  attempt  to 
remove  the  placenta  by  Credo  expression  after  the  woman  is  deeply  narcotized.

A  careful  disinfection  of  the  external  genitals  and  the  lower  vagina  should  now  be  made.  No 
hemorrhage  is  so  dangerous  that  such  preparations  may  be  neglected.  The  danger  of  sepsis  would 
thus  replace  t  hat  of  hemorrhage.  The  parts  have  already  been 
clipped  or  shaved,  and  they  have  been  well  washed  with  anti- 
septic solutions  during  the  delivery.  Before  inserting  the  hand 
the  externals  should  again  be  liberally  sponged  with  1  :  1500 
bichlorid  and  then  with  1  per  cent,  lysol  solution.  The  vagina 
should  be  well  flushed  out  with  1  per  cent,  lysol  solution,  using 
large  cotton  or  gauze  sponges.  The  use  of  rubber  gloves  can- 
not be  too  warml}^  recommended  for  obstetric  practice,  and, 
especiall}' for  this  dangerous  operation  of  invading  the  uterine 
cavity,  they  are  almost  indispensable.  The  gloves  should  be 
long,  should  fit  well,  and  they  should  be  drawn  on  dry,  over 
sterile  hands.  A  sterile  towel  is  laid  on  the  abdomen,  and  the 
hand  put  into  the  vagina,  avoiding  the  anus  and  perineum. 
The  left  hand  is  usually  found  to  be  most  adapted  for  internal 
work.  The  fingers  spread  out  in  the  cervix  so  that  the  mem- 
branes and  cord  fall  into  their  grasp,  then  the  tips  of  the  fin- 
gers are  brought  together  to  form  a  cone  for  passage  of  the 
contraction  ring  (Fig.  713).  It  is  seldom  necessary  to  use  force 
in  passing  this  point.  If  ergot  has  been  administered  or  if  the 
contraction  ring  has  closed  do^\Ti,  it  may  be  necessary  to  press 
the  fingers  firmly  through  the  constriction.  Profound  anes- 
thesia aids  much.  The  fingers  seek  the  edge  of  the  placenta, 
and  the  hand  on  the  belly  forces  the  uterus  down  over  the  inside 
fingers  (Fig.  714).  With  a  gentle  combined  movement  the  pla- 
centa is  separated  from  its  bed.  It  is  usually  very  easy  to 
separate  the  organ;  but  if  it  is  pathologically  adherent,  tough 
strands  will  have  to  be  sawn  through  by  the  fingers  supported 
by  the  outside  hand.  A  warning  not  to  bore  into  or  through 
the  uterus  must  be  given,  because  this  is  sometimes  surprisingly 
easy  (Fig.  71o).  After  the  placenta  h;is  been  cleanly  separated 
the  two  hands  give  the  uterus  a  brisk  massage,  and  a  contrac- 
tion will  expel  the  hand  containing  the  placenta.  It  is  better 
to  let  the  uterus  expel  the  hand  with  the  placenta  than  to  drag 
the  latter  out.  After  wa.shing  the  blood  off  the  hand,  and  again 
sponging  the  parts  with  antiseptic  solution,  the  hand  is  once 
more  inserted,  and  the  whole  interior  of  the  uterus  carefulh*  in- 
spected. One  must  be  absolutely  certain  that  the  uterus  is 
perfectly  empty.  Care  should  be  taken  to  remove  all  the 
membranes  antl  thickened  decidua.  The  rubber  gloves  are  so 
slipjx'rjMhat  shreds  of  decidua  cannot  be  grasped.  One  misses 
the  sharp  finger-nail  in  such  cases.  Tlie  :uitlior  uses  a  jiiece  of 
gauze  for  the  purpose  of  cleaning  off  the  decidua  and  mem- 
branes, as  in  Fig.  71G.  One  may  now  give  a  hot  0..5  per  cent, 
lysol  intra-uterine  douclie,  which  usually  causes  firm  contrac- 
tion and  retraction.     A  hypodermic  oi  ergone,  ergotole,  or 

aseptic  ergot  is  also  administered.         '  Fio.  716.— Hand  Armed  with  Gauze

adherent  on  tlie  uterine  wall,  a  firm  uterovaginal  tamponade  is  made  and  the  gauze  r(>moved  in 
forty-eight  hnur?;.     Missing  portions  often  come  awaj'  with  the  gauze. 

Treatment  after  the  Placenta  is  Out. — In  all  labor  cases,  as  soon  as  the  placenta 
has  been  delivered,  inspect  it  carefully  before  throwing  it  in  the  drainage-jar.  This 
is  done  at  once,  because  if  a  piece  of  it  is  missing,  one  may  adopt  appropriate  meas- 
ures, and  will  not  be  surprised  by  a  hemorrhage  after  the  patient  has  been  prepared

for  bed,  or,  indeed,  after  the  physician  is  reatly  to  leave  tlie  house.     If  convinced 
that  a  piece  of  the  placenta  has  been  retained,  it  must  ])e  removed. 

If  the  membranes  are  missing  or  incomplete,  shoukl  you  enter  the  uterus  for 
their  removal?  Opinions  of  authorities  differ.  In  maternity  hospital  practice, 
with  the  protection  of  sterile  rubber  gloves  and  an  aseptic  confinement  room,  the 
author  removes  such  retained  membranes.  If  only  a  third  or  a  half  of  the  mem- 
branes is  left,  providing  there  is  no  hemorrhage,  the  removal  of  tlu^  missing  portion 
may  be  trusted  to  nature.     In  private  practice,  under  usual  conditions,  it  is  safer

to  trust  the  expulsion  of  the  membranes  to  the  uterus.  Ergot  and  hydrastis  are 
given  for  two  weeks,  and  usually  the  uterus  gets  rid  of  the  membranes  in  the  first 
eight  days.     Sapremic  fever  is  not  rare,  but  usually  subsides  safely. 

Routine. — In  all  cases  of  i)()stpartum  hemorrhage  a  brisk  uterine  massage  is  the 
first  action.  Uterine  contraction  has  a  deterrent  effect  even  on  the  flowfrom  cervical 
laceration.  The  first  motions  should  be  slow  and  even,  but  unless  the  uterus  re- 
sponds promptly,  they  should  be  rapid,  and  spread  all  over  the  fundus  and  also  at 
the  sides,  near  the  tubes  and  ovaries.  Another  method,  recommended  by  Kumpf, 
is  compression  vibratory  massage.     The  uterus  is  grasped  In-  the  right  hand,  pressed

down  into  the  inlet;  the  arm  is  held  rigid,  and  then  a  rapid  vibratory  massage  is 
administered,  the  excursions  of  the  muscles  being  very  small.  If  the  other  hand 
happens  to  be  in  the  uterus,  a  combined  massage  may  be  thus  given.  If  a  meciianical 
vibrator  is  available,  it  may  be  used.  As  an  aid  to  uterine  massage  the  accoucheur 
mav  irritate  the  sympathetic  ganglia  around  the  bifurcation  of  the  aorta.  The 
hand  very  gently  rubs  over  this  region,  and  uterine  contractions  often  result. 
If  the  hemorrhage  is  very  profuse,  threatening  the  woman's  life,  the  same  hand 
compresses  the  aorta  firmly  against  the  spine  (Fig.  717),  as  recommended  by 
Baudelocque  in  179G.     This  will  check  the  flow  until  the  uterus  has  obtained  control

of  itself,  or  until  the  attendant  can  iiroparo  the  patient,  his  instruments,  gauze, 
etc.,  for  effective  hemostasis. 

Second,  ergot,  a  dram  of  the  fluidcxtract,  is  administered  by  mouth,  and  in 
urgent  cases  a  hypodermic  of  the  same  is  given.  The  best  place  to  inject  is  deeply 
into  the  outer  muscles  of  the  thigh,  and  an  aseptic  ergot,  coming  in  little  glass  ])ulbs, 
is  employed.  In  no  instance  should  the  accoucheur  wait  for  the  action  of  the  drug, 
which  may  be  absent,  or  at  least  delayed  fiNe  to  thirty  minutes,  during  which  time

the  woman  may  die.    Experience  has  proved  that  it  is  not  wi.se  to  give  ergot  until 
the  placenta  has  left  the  contracting  portion  of  the  uterus. 

The  next  procedure  (third)  is  the  hot  uterine  douche.  The  douche-bag  should 
be  prepared  in  every  labor,  and  should  be  hung  near  the  bed,  properly  protectetl 
against  contamination.  The  patient  is  brought  across  the  bed  with  the  hips  well 
over  the  edge;  the  parts  are  sterilized,  and  everything  is  arranged  as  for  manual  re- 
moval of  the  -placenta;  one  hand  is  inserted  into  the  uterus,  and,  aided  l)y  the  outside 
hand,  all  clots,  membranes,  and  shreds  gently  wiped  out,  after  which  the  douche 
nozzle  is  introduced  into  the  uterus  and  one  quart  of  hot  (120°  F.)  0.5  per  cent,  lysol

solution  allowed  to  flow  throusli.  AH  air  should  be  evacuated  from  the  douche-tube 
before  its  insertion.  The  danger  of  air-embolism  is  emphasized  by  most  authors. 
Experiments  on  horses  and  dogs  have  shown  that  immense  ciuantities  of  air  can  be 
injected  into  their  veins,  with  the  production  of  only  mild  and  transient  symptoms. 
In  th(^  human,  however,  clinical  experience  furnishes  many  examples  of  severe  col- 
lapse and  death  from  the  admission  of  air  to  the  veins. 

Some  authors  advise  cold  or  even  iced  water  instead  of  hot  for  the  douche. 
The  hot  water  is  better  because  it  is  easier  to  obtain  than  sterile  cold  water;  it 
floes  not  shock  an  already  weakened  woman,  and  it  is  just  as  efficient.  Sterile 
vinegar  and  lemon-juice  have  l)een  added  to  the  douche  or  used  alone.  In  the  great 
majority  of  cases  the  above  treatment  will  suffice  to  stop  the  hemorrhage  cora=

pletely.  If  it  does  not,  one  has  to  do  with  an  extensive  laceration  or  a  bad  case  of 
atony  of  the  uterus.  The  laceration,  of  course,  will  have  been  discovered  when  the 
hand  was  inserted  either  for  removal  of  the  placenta  or  preliminary  to  the  douche. 
Treatment  of  lacerations  naturally  occurs  at  this  point,  but  wo  will  leave  the  dis- 
cussion until  later.  Should  the  diagnosis  of  severe  inertia  be  made,  one  has  to 
adopt  other  measures.  Time  is  an  element  in  such  cases.  Cli^•e  the  uterus  a  little 
time  and  it  wiW  contract,  but  one  must  not  allow  the  bleeding  to  continue  all  the 
while.  To  stop  the  hemorrhage  and  to  give  the  uterus  this  ojiportunity  (fourth) 
cnmprefis  the  uterus  befurcn  the  two  hands,  as  in  Fig.  718.  The  cervix  is  grasped  by 
the  whole  hand  and  folded  together,  while  the  outside  hand  forces  the  uterus  down 
firmly  against  the  pubis  and  inside  hand.     One  may  feel  the  uterus  gradually  as-

suming  its  normal  shape  and  consistence,  and  when,  after  ten  or  fifteen  minutes, 
the  pressure  is  relaxed,  the  physician  finds  that  the  flow  has  ceased,  he  maj'  remove 
his  hands.  Should  the  flow  continue  in  spite  of  this  manoeuver,  or  should  it  recom- 
mence after  he  has  removed  his  hands,  no  further  time  and  l)lood  should  be  wasted, 
hut  the  uterovaginal  tract  should  he  packed  (fifth). 

Uterine  Tamponade. — One  may  tampon  the  uterus  with  gauze,  using  the  hands  alone,  or 
with  the  single  aid  of  the  uterine  packing  forceps,  or  by  sight,  having  drawn  the  uterus  down  with

the  vulsellum  forcop.s  and  spread  the  genitals  by  specula.  The  kind  of  gauze  is  very  important 
and  the  author  recommends  that  described  in  the  Appendix. 

Most  often  it  will  be  necessary  to  operate  with  insufficient  help,  and  then  th(>  second  method 
is  employed  (Fig.  720).  The  operator  puts  the  left  hand  into  the  vagina,  the  fingers  inside  the 
uterus  as  high  as  possible. 

With  long  uterine  packing  forceps  the  end  of  the  strip  is  carried  up  to  the  top  of  the  uterus, 
taking  care  that  the  tip  of  the  forceps  does  not  catch  on  the  contract  ion  ring  or  in  a  fold  of  the  re- 
laxed uterine  wall.  A  sterile  towel  is  laid  on  the  belly,  and  with  his  right  haml  the  ojierator  de- 
termines that  the  tip  of  the  forceps  carrying  the  gauze  is  really  in  the  highest  point  of  the  uterus. 
The  gauze  is  then  evenly  packed  into  the  uterine  cavity,  from  side  to  side,  and  from  above  down-

ward.  An  assistant  steadies  the  fundus,  or  tho  operator  from  time  to  time  assures  himself  that 
the  uterus  is  being  evenly  filled.  The  inside  hand  acts  as  a  grooved  channel  along  which  the  gauze 
and  forceps  find  easv  direction.  The  first  part  must  be  most  firmly  placed.  \A'hen  the  uterus  is 
full,  the  forceps  are\aid  temporarily  in  the  basin;  two  fingers  of  the  left  hand  are  placed  against 
the  tampon;  the  right  hand  grasjjs  the  uterus  through  the  sterile  towel,  and  the  fingers  force  the 
gauze  upward  more  firmly  into  the  fundus,  thus  leaving  room  in  the  cervix  for  more  gauze.  This 
manocuver  must  be  performed  carefully  and  gently,  and  one  must  leave  a  vent  for  the  escape  of  air, 
otherwise  there  is  danger  of  air-embolism.  It  is  well  to  have  the  trunk  a  little  higher  than  the 
pelvis.  The  nurse  holds  the  gauze  jar  near  the  vulva,  exactly  as  in  the  illustration  (Fig.  720).  In 
the  absence  of  a  nurse  or  other  person  to  hold  the  jar  of  gauze  it  may  be  held  between  the  accou- 
cheur's knees,  as  he  sits  before  the  patient,  with  his  heels  caught  on  a  rung  of  the  chair. 

The  writer,  in  several  cases  of  great  urgency,  applied  the  gauze  successfully  with  the  hands, 
the  left  hand  forcing  the  strip  up  into  the  uterus  as  it  was  fed  into  it  by  the  right  hand  (Fig.  719). 


Ftfi.  722. 


Utercs  Correctly  Plugged. 


If  the  operator  prefers  the  third  method,  a  table,  good  light,  and  several  assistants  are  re- 
quired. A  broad  speculum  retracts  the  perineum;  one  cervix  forcejjs  is  placed  on  the  anterior  lip 
01  the  cervix,  and,  if  necessary,  one  on  the  posterior  lip,  the  operator  holding  one,  the  assistant,  the 
other.  The  right  hand,  armed  with  the  long  forceps,  inserts  the  gauze,  while  the  hand  outside 
controls  the  fundus  uteri  and  guards  against  false  movements  (Fig.  721). 

In  all  cases,  after  the  uterus  is  jirniUj  plugged,  the  vagina  is  firmly  tamponed  with  the  re- 
maining portion  of  the  strip.  Diihrsscn  advised  tamponing  the  vagina  with  cotton,  which  is  better 
in  some  respects,  but  gives  more  pain  and  trouble  in  removal. 

In  all  but  a  very  few  cases  packing  will  stop  the  bleeding.  Chrobak,  Ahlfeld, 
Bumm,  von  Braun,  report  10  failures  in  120  cases,  but  an  exact  study  of  the  his- 
tories shows  that  too  nuich  was  expected  of  the  operation.  The  author  has  plugged 
the  uterus  over  a  hundred  times  for  conditions  not  due  to  lacerations.  Only  twice 
was  it  necessary'  to  rephice  the  pack  with  a  second  one.  In  two  cases  of  laceration 
of  the  cervix  ^vith  hemophilic  diathesis  the  women  died  of  hemorrhage.  In  two 
50

THE    PATHOLOGY    OF   LABOR 


cases  of  atony  of  the  uterus  with  homopliiHc  diathesis  it  was  necessary  to  repack 
with  gehitinized  gauze. 

Without  doubt  most  of  the  re])orted  failures  are  due  to  poor  technie :  the  gauze 
is  not  put  in  correctly.  Fig.  722  shows  the  parturient  canal  correctly  packed ;  Fig. 
723,  a  case  where  the  operator  has  failed  to  grasp  the  situation.  If  the  first  tampon 
is  unsuccessful,  it  should  be  removed  and  another  inserted  more  snugly.  If  ab- 
solutely sterile  and  non-toxic  gelatin  (]\Ierck)  is  at  hand,  the  gauze  should  be  well 
saturated  with  it  before  being  applied.  In  emergency,  2  ounces  of  French  gelatin 
are  melted  into  about  24  ounces  of  boiling  water  and  boiled  violently  over  a  hot  fire, 
with  constant  stirring,  for  twenty  to  thirty  minutes.  It  is  poured  over  the  gauze 
shortly  before  the  operation.     Another  resource  is  to  sew  the  cervix  together  over

the  uterine  plug.  (See  Fig.  725.)  In  o]:>stinate  cases  it  may  be  necessary  to  ex- 
tirpate the  uterus,  but  few  are  the  reported  recoveries.  After  the  tamponade  ergot 
is  given  as  usual,  and  the  hand  should  guard  the  uterus,  massaging  it  lightly,  or 
rubbing  the  aorta  gently,  if  there  be  any  tendency  to  further  atony,  for  several 
hours.  A  tight  abdominal  binder  is  recommended  l)y  some,  but  the  author  has  not 
seen  any  real  indication  for  it.  It  is  ))ctter  to  force  the  uterus  down  from  the  out- 
side, while  the  balled  fist  exerts  counterpressure  from  the  perineum. 

The  gauze  is  removed  in  twenty-four  to  thirty-six  hours,  and  must  be  with- 
drawn very  slowly,  twenty  to  thirty  minutes  being  consumed  in  the  operation.  One 
must  be  prepared  to  pack  again;  but  the  author  has  never  found  it  necessary  in 
cases  of  atony.     (For  further  details  and  history  of  uterovaginal  tamponade  the

reader  is  referred  to  my  article  in  tlie  American  Journal  of  Ojjstetrics,  1903,  vol. 
xlvii,  No.  4.) 

To  sum  up  l)riefly  the  treatment  of  atonic  postpartum  hemorrhage:  First,  if 
the  plac(>nta  is  in  the  uterus,  massage;  failing  this,  expression  of  the  placenta; 
failing  this,  manual  removal.  Second,  after  placenta  is  out,  massage,  ergot,  hot 
uterine  douche  with  cleansing  of  uterine  cavitj^  compression  of  the  uterus  in  ante- 
flexion;  failing  all  these,  uterine  tamponade. 

Many  other  methods  have  been  proposed,  and  occasionally  they  will  prove  u.seful.  Com- 
pression of  the  abdominal  aorta  may  be  omploj'cd  as  a  temporary  expedient  until  one  can  prepare 
for  more  pcnnanent  measures.  Packing  the  vagina  with  a  hall  of  gauze,  a  towel,  or  anything 
sterile  that  is  near  at  hand,  and  pressing  the  uterus  against  this  from  the  outside,  may  limit  the

flow  until  the  aceouoheur  ean  procure  a  hot  douche  or  gauze  for  packing.  Squeezing  a  sponge  with 
vinegar  or  lemon-juice  in  the  uterus  has  already  been  mentioned.     These  fluids  must  be  sterile. 

Fritsch  recommended  pulling  the  fundus  forward  over  the  pubis  and  fllling  up  the  space  be- 
tween it  and  the  promontory  with  towels,  after  which  one  was  to  put  on  a  very  tight  abdominal 
binder.  The  uterus  has  been  folded  together  from  the  side,  twisted  on  its  axis,  turned  inside  out, 
ligated,  etc.  Chlorid  of  iron  and  Monsell's  solution  have  been  injected,  and  even  packed  in  the 
uterus  on  gauze.  This  is  unciualifiedly  condemned,  because  harmful  and  unnecessary.  The  gauze 
useil  for  packing  might  be  saturated  with  sterile  and  non-toxic  gelatin,  or  with  sterile  blood  from 
the  husband  or  relative,  the  idea  being  to  su]iply  the  missing  thrombokinase.  Suprarenin  is 
powerless  to  cause  uterine  contractions  unless  injected  directly  into  the  uterine  muscle,  as  pro- 
posed by  Xeu.  At  the  operation  of  cesarean  section  I  have  seen  strong  contraction  of  the  uterus 
follow,  at  once,  the  intramuscular  injection  of  1  c.c.  1  :  10,000  adrenalin.  This  is  now  put  up  in 
sealed  bulbs.  Pituitrin,  10  drops  hypodennically,  repeated  if  reciuired,  has  been  found  efficacious 
in  atony  of  the  uterus  (Foges).     Cliven  by  douche  or  on  packing,  both  drugs  are  useless. 

Parscnow  recommended  ])ulling  the  cervix  down  to  the  \ulva  with  vulsellum  forceps,  thus

stretchirifi  and  kinking  tho  uterine  vessels,  and  Plenkel  advised  ])laring  a  bullet  forceps  temporarily 
on  the  uterine  vessels  at  the  sich's  of  the  uterus  throujih  tlie  hiteral  forniees.  Henkel's  inanciuver 
is  not  entirely  safe,  and  has  been  seldom  used,  but  rarsciio\v"s  is  safe  and  may  control  the  bleeding 
more  or  less  until  the  uterus  may  be  packed. 

Momburg  jjroposed  circular  constriction  of  the  waist  with  a  rubber  tube,  to  cut  off  the  circu- 
lation in  the  lower  half  of  the  body,  which  he  had  used  successfully  in  surgery.  Fig.  724  shows  the 
belt  ajiplied.  By  constricting  the  aorta  hemorrhage  is  stopped,  and  the  sudden  anemization  of 
the  uterus  stimufates  it  to  strong  contraction.  Sigwart  reports  24  successful  cases,  anfl  because  of 
its  apparent  safety  even  reconunends  the  procedure  for  midwives.  In  the  Revue  de  Chirurgie  for 
Ma}',  1910,  a  death  from  heart  paralysis  on  the  removal  of  the  belt  is  reported,  and  reference  made 
to  gangrene  of  the  thigh,  intestinal  and  jnilmonary  hemorrhage,  and  a  possible  death  noted  by 
deBovis.  Buck  reports  a  case  of  gangrene  of  the  intestine,  and  Pagenstecher  one  of  ischemic 
paralysis  of  the  distal  end  of  the  spinal  cord.  Latest  experience  with  the  belt  shows  that  it  may  not 
be  used  in  cases  of  disease  of  the  heart,  blood-vessels,  kidneys,  or  intestines,  nor  in  Basedow's. 


Fig.  72.5. — I'teru.s  Being  Closed  Over  a  Plug. 

The  fir.st  half  of  the  wound  on  both  sides  is  closed  with  continuous  catgut,  the  middle  part  with  silkworm-gut  sutures, 

which  are  removed  in  twenty-four  to  thirty-six  hours. 

In  severe  anemia  it  is  tlangerous  unless  the  limbs  are  tied  with  an  lilsmarch  before  application  of 
the  constriction.  The  constrictor  is  applied  with  the  body  slanting,  to  allow  the  intestines  to 
gravitate  toward  the  diaphragm.  As  soon  as  possible  after  the  bleeding  has  been  definitively 
stopped  it  is  removed.  Before  removing  the  belt  salt  solution  is  to  be  given  hypodermically. 
The  Esmarch  bandages  should  be  removed  one  at  a  time,  leaving  an  interval  of  ten  minutes,  and 
the  limbs  should  be  kept  elevated  until  the  volume  of  blood  is  such  that  the  heart  will  not  "pump 
empty."  To  substitute  the  belt,  Rissmann  invented  an  aortic  clamp  similar  to  the  tonsil  com- 
pressor. 


TREATMENT  OF  LACERATIONS 
When  a  tear  of  the  parturient  canal  ha.s  been  discovered,  the  treatment  of  the 
case  must  be  modified  somewhat.     If  yon  compress  a  cUtoris,  vtilvar  or  lower  vaginal 
tear  for  a  few  minutes,  very  often  the  bleeding  will  cease  and  the  regular  conduct  of 


POSTPARTUM   HEMORRHAGE  789 

the  third  stage  will  not  need  to  Ije  altered.  If  compression  does  not  suffice,  a  few- 
sutures  will  always  do  so. 

Higher  vaginal  tears  and  cervix  tears,  especially  in  placenta  previa,  may  cau.se 
most  serious  hemorrhage.  It  is  important  to  get  rid  of  the  placenta  at  once  and 
get  contraction  and  retraction  of  the  uterus.  This  part  of  the  treatment  is  the 
same  as  for  atony.  If  the  bleeding  continues,  two  courses  are  open — one,  utero- 
vaginal tamponade,  the  other,  suture  of  the  laceration.  One  may  combine  the  two 
procedures.  AVithout  doubt  the  best  way  to  stop  hemorrhage  from  a  laceration  is 
to  sew  up  the  tear,  but  it  may  be  impossible  to  do  this  because  of  lack  of  proper 
preparations,  of  assistants,  light,  or  skill.  Then,  too,  sometimes  the  bleeding  is  so 
profuse  that  you  cannot  see  where  to  place  the  stitches,  the  whole  field  being  a  lake 
of  blood.  It  may  also  be  inadvisable  to  sew  up  the  tear  ])ecause  of  sepsis,  or  be- 
cause the  facilities  are  not  at  hand  for  aseptic  work.  It  may  thus  be  safer  to  leave 
the  wound  open  for  drainage.  In  such  cases  the  tampon  will  be  indicated,  but  it  is 
not  so  certain  a  remedy  as  in  atony  of  the  uterus. 

When  plugging  a  uterus  and  tear,  the  operator  must  be  careful  not  to  enlarge 
the  latter  by  pushing  in  too  much  gauze,  and  the  whole  parturient  canal  must  always 
be  snugly  and  smoothly  filled,  never  the  vagina  alone. 

Lacerations  are  sewed  as  sho\\'n  in  Fig.  689,  and  Fig.  687,  p.  742.  Free,  perhaps 
torrential,  bleeding  may  render  such  operations  difficult,  and  I  have  found  the  follow- 
ing measures  useful,  to  enable  me  to  see  the  field.  Compression  of  the  aorta  (now, 
perhaps,  Momburg  tourniquet) ;  traction  on  the  lips  of  the  cervix  with  cervix  for- 
ceps; packing  one  side  of  the  cervix  tear  while  the  other  is  sutured;  compression  of 
the  bleeding  surface  with  a  large  wad  of  dry  cotton  or  the  hand  for  twenty  minutes ; 
Henkel's  method  of  clamping  the  bases  of  the  broad  ligament  with  bullet  forceps; 
filling  the  uterus  tight  full  of  gauze,  and  sewing  the  cervix  together  over  the  plug 
(Fig.  725).     Occasionally  a  spurting  vessel  may  be  clamped  and  ligated. 

After-treatment. — All  danger  is  not  past  when  the  hemorrhage  has  been  stopped. 
The  patient  may  die  from  the  loss  of  blood.  Unless  one  has  plenty  of  medical 
assistants,  this  part  of  the  treatment  will  have  to  be  left  until  the  accoucheur  has 
stopped  the  active  hemorrhage.  This  is  the  advantage  of  doing  obstetrics  in  a 
maternity — while  stopping  the  loss  of  blood  an  interne  may  be  filling  the  patient's 
blood-vessels  with  salt  solution  or  blood  transfusion  may  be  done. 

During  ol^stetric  operations  in  general,  and  the  treatment  of  hemorrhage  in 
particular,  the  patient  should  be  kept  covered  and  warm.  After  a  hemorrhage  has 
l)een  checked  the  patient  sliould  be  warmly  covered  in  bed  and  surrounded  ])y  hot- 
water  bottles.  If  she  is  in  much  shock,  the  foot  of  the  bed  should  be  elevated  at 
least  two  feet,  and  a  hypodermic  injection  of  camphorated  oil  given.  To  tide  the 
patient  over  a  fainting  spell  give  a  hypodermic  of  aromatic  spirits  of  ammonia,  and 
let  her  sniff  some  smelling  salts.  While  doing  these  things  saline  solution  for  sul)- 
cutaneous  administration  should  be  prepared.  Sterile  salt  in  2-dram  vials  should  be 
carried  in  the  obstetric  satchel.  A  douche-bag,  a  bath-thermometer,  and  salt  solu- 
tion needle  should  be  boiled.  Two  drams  of  sterile  salt  are  placed  in  the  bag;  the 
end  of  the  tube,  armed  with  the  needle,  is  also  put  in  the  bag;  then  one  quart  of 
boiling  water  is  pouretl  on  the  salt.  The  mouth  of  the  bag  is  stopped  with  a  large 
wad  of  sterile  cotton,  and  the  bag  is  held  under  the  cold-water  tap  or  in  a  dish-pan 
of  cold  water  until  the  thermometer  registers  115°  F.  (Fig.  726). 

The  skin  under  the  breasts  is  painted  with  tincture  of  iodin,  and  the  needle, 
with  the  solution  flowing,  is  put  in  below  the  manniiary  gland.  The  accoucheur 
seeks  to  direct  the  needle  into  the  connective  tissue  under  the  glandular  portion  of 
the  breast.  The  bag  is  now  raised  4  feet.  As  much  as  32  ounces  ma}'  run  under  the 
skin.  It  is  advisable  to  lower  the  bag  occasionally  to  prevent  overstretching  and 
too  rapid  opening  up  of  the  lymph-spaces.  If  the  case  is  critical,  the  other  side, 
as  well  as  the  two  flanks,  may  be  injected.     In  one  patient  I  injected  116  ounces  of 


790 


THE    PATHOLOGY    OF    LABOR 


saline  solution  in  one  sitting,  using  the  4  points  named.  The  patient  recovered. 
This  patient  also  absorbed  2  quarts  from  the  rectum.  Such  inunense  quantities  are 
rarely  needed.  Shall  you  inject  the  salt  solution  while  the  hemorrhage  is  still  going 
on?  Yes,  sul)cutaneously,  not  intravenously.  The  blood  lost  then  will  not  be  pure, 
but  mixed  with  salt  sohition,  and  it  is  not  so  precious.  By  the  time  a  quart  has 
been  absorbed  the  accoucheur  must  have  the  hemorrhage  in  his  control,  or  the 

patient  will  have  died.  Some  authors  ad- 
vise against  the  use  of  saline  solution  until 
after  the  flow  has  ceased.  I  think  their  ob- 
jections are  theoretic.  "Without  doubt  salt 
solution  has  saved  many  lives. 

The  writer  has  never  seen  fit  to  bandage 
the  limbs — so-called  autotransfusion.  The 
position  of  the  body,  with  the  foot  of  the  bed 
elevated,  aided  by  saline  solution,  is  suf- 
ficient. 

Per  rectum,  salt  solution,  with  perhaps 
three  ounces  of  coffee,  is  quickly  absorbed, 
and  a  quart  may  be  administered  every  three 
hours.  It  is  not  wise  to  administer  it  per 
rectum  until  the  hemorrhage  has  been  per- 
manently stopped,  because  if  any  local  treat- 
ment is  to  be  carried  out,  the  discharge  from 
the  bowel  may  infect  the  field,  the  hands,  in- 
struments, gauze,  etc.,  so  that  sepsis  may  be 
the  direct  result.  One  of  the  most  unwel- 
come incidents  in  any  obstetric  operation  is 
a  flow  of  liquid  feces  from  the  anus,  and  the 
writer  is  certain  that  this  has  caused  infection 
and  death  many  times. 

Lower  transfused  human  blood  in  1666, 
but  although  the  operation  has  been  attempted  many  times  since,  success  has  not 
been  obtained  until  recently,  when  the  technic  of  artery  to  vein  suture  has  been 
perfected.  Lespinasse  gives  the  literature  to  date.  From  my  experience  with 
transfusion  in  hemophilic  new-born  infants  I  would  say  that  in  desperate  cases  of 
postpartum  hemorrhage  the  woman's  empty  vessels  should  be  filled  with  blood 
from  her  husband  or  near  relative,  if  healthy,  of  course.

The  radial  artery  is  joined  to  tlie  median  basilic  vein  by  means  of  the  old  m(>thod  of  Payer  or

apparatus  which  is  more  practical  for  one  not  skilled  in  blood-\-essel  surgery  (Fig.  727). 

By  mouth,  the  patient  may  have  wine,  hot  coffee,  water,  or  a  hot  oyster-stew. 
If  the  patient  vomits,  she  usually  feels  relieved,  after  which  li(iuids  may  again  be 
given,  using  care  not  to  overload  the  stomach. 


POSTPARTUM   HEMORRHAGE  791 

During  the  first  week  nourislinient  must  be  given  freely.  The  bed  is  lowered  in 
two  or  three  days  or  sooner,  depending  on  the  condition  of  the  patient.  It  is 
lowered  a  few  inches  at  a  time  to  avoid  syncope.  Not  seldom,  after  severe  hemor- 
rhages, the  puerpera  will  have  a  rise  of  temperature  to  102°  F.  within  the  first 
twenty-four  hours.  This  is  reaction  fever,  and  will  go  down  without  treatment. 
But  occasionally  sepsis  follows  in  the  wake  of  a  severe  loss,  first,  because  the  resis- 
tance of  the  patient  is  so  much  lowered  that  infection  finds  easy  access,  and, 
second,  l^ecause,  in  the  excitement  and  unpreparedness  attending  most  of  such  cases, 
the  rules  of  asepsis  are  forgotten  or  are  impossible  of  being  carried  out  in  detail. 
Sepsis  under  these  conditions  is  likely  to  follow  a  severe  course. 

The  milk  secretion  is  diminished,  Ahlfeld's  statistics  to  the  contrary  notwith- 
standing. Ahlfeld  had  strong  peasant  women  to  deal  with.  The  high-strung 
American  mother  cannot  stand  the  drain  of  lactation  after  severe  loss  of  blood. 
My  experience  has  been  unequivocal  on  this  point,  and  I  notice  that  von  Braun 
warns  against  forcing  the  nursing  of  the  infant  on  neurasthenic  women.  One  may 
permit  a  partial  breast-feeding  until  the  woman  has  completely  recovered  from  the 
exhaustion  of  the  hemorrhage.  Some  women  recover  very  slowly  from  the  spanemia 
and  require  blood-tonics  for  long  periods.  The  best  treatment  the  writer  knows  for 
such  cases  of  severe  hemorrhage  is  living  at  the  seashore,  and  the  woman  should  be 
sent  there  as  soon  as  she  can  bear  the  journey. 


LATE  PUERPERAL  HEMORRHAGES 

Even  after  delivery  the  woman  is  not  safe  from  the  dangers  of  bleeding,  since 
such  may  occur  as  late  as  the  fifth  week  postpartum.  A  hemorrhage  which  begins 
after  the  first  day  after  labor  is  called  late,  though  some  authors  distinguish  between 
those  which  occur  in  the  early  puerperium  and  those  of  the  late  puerperium.  Some- 
times, without  apparent  cause,  the  puerpera  begins  to  flow,  and  the  amount  of 
blood  lost  may  be  so  great  that  a  serious  anemia  or  even  death  results. 

Etiology. — Among  the  commonest  causes  may  be  noted  retention  of  placental 
fragments,  of  thick  membranes,  of  thick  decidua  (especially  in  abortions),  and  some- 
times simply  a  hard  blood-clot.  A  large  piece  of  placenta  may  come  away,  more  or 
less,  or  not  at  all,  decomposed,  as  late  as  the  twelfth  day,  and  usually  there  is  not 
much  bleeding.  Cases  are  on  record  of  the  retention  of  pieces  of  placenta  for  as  long 
as  eleven  months,  and  Ries  found  placental  villi  in  the  uterine  vessels  eighteen  years 
after  the  last  delivery.  Ramsbotham  records  a  case  where  the  whole  placenta  was 
retained,  and,  as  far  as  the  woman  knew,  never  came  away.  Small  and  thin  pieces 
of  placenta  may  dissolve  in  the  lochia,  which  are  then  profuse,  prolonged,  bloody, 
and  perhaps  fetid.  The  same  may  be  said  of  membranes  and  decidua.  If  bits  of 
placenta  or  decidua  do  not  become  infected,  blood  is  deposited  on  them  in  successive 
layers,  and  a  fibrinous  or  placental  polypus  results.  These  keep  up  irregular  hemor- 
rhage until  they  are  removed,  or  they  become  infected,  break  do\\Ti,  and  are  dis- 
charged piecemeal,  with  fetid  discharge  and  fever,  sometimes  with  hemorrhages, 
or  a  pyemia  may  ensue. 

Subinvolution  stands  nexi,  in  frequency,  the  large  boggy  uterus  bleeding  on  the 
slightest  provocation.  Low  grades  of  infection  are  responsil^le  for  many  cases  of 
subinvolution.  Displacements  of  the  uterus  are  usually  part  of  the  same  process, 
and  in  retroflexion  of  the  puerperal  uterus  hemorrhages  are  not  infrequent  and  pro- 
longed, and  bloody  lochia — in  some  cases  for  six  or  eight  weeks — are  very  common. 
Favored  by  sul)involution  and  displaced  by  a  full  bladder  or  rectum,  the  uterus 
may  bleed,  and  a  disquieting  degree  of  anemia  may  result. 

Nervous  influences  unquestionably  play  a  role.  I  saw  a  very  serious  hemor- 
rhage result  from  relaxation  of  the  uterus  on  the  eleventh  day  when  the  puerpera 


792  THE    PATHOLOGY    OF   LABOR 

had  been  frightened  l)y  a  domestic  (luarrel.  A\'e  know  that  the  metises  may  cease, 
and  that  metrorrhagia  may  ensue,  upon  a  nervous  shock. 

Sudden  physical  strain  often  causes  a  reappearance  of  the  bloody  lochia,  as  is 
so  ohen  observed  when  the  ])uerpcra  gc^ts  up  for  the  first  time.  Severe  hemorrhages 
at  this  tune  are  rare,  but  do  occur  (sul)involution). 

As  occasional  causes  ma}'  be  mentioned  myomata,  especially  the  nmral  and 
submucous  varieties,  carcinomata,  cervical  erosions,  ulceration  of  a  cervical  vessel, 
rupture  of  a  small  uterine  or  cervical  hematoma,  inversion  of  the  uterus,  chorio- 
epithelioma,  secondary  hemorrhages  after  suture  of  a  cervix  tear,  as  occurs  some- 
times after  gynecologic  operations,  traumatism  from  coitus,  sometimes  with  rupture 
of  the  vagina,  and  puerperal  septicemia  with  softening  of  the  thrombi  of  the  pla- 
cental site.     The  last  form  of  hemorrhage  is  very  fatal. 

Diagnosis. — Three  points  must  be  settled — first,  is  there  anything  in  the  uterus? 
secontl,  is  it  simply  a  case  of  relaxation  or  subinvolution?  third,  is  there  a  neoplasm? 

Early  in  the  puerperium  a  vaginal  examination  is  forbidden  unless  urgently 
indicated,  but  a  rectal  exploration,  combined  with  the  external  hand,  gives  nearly 
as  much  information  and  is  quite  safe.  Later  in  the  puerperium,  after  the  four- 
teenth day,  a  vaginal  examination  may  be  made.  If  the  cervix  is  too  soft,  patulous, 
and  the  uterus  large  and  globular,  a  retained  cotyledon  of  the  placenta  may  be 
suspected.  Sometimes  it  may  be  felt  through  the  open  cervical  canal.  If  the 
uterus  is  evenly  enlarged,  of  a  soft,  doughy  consistence,  but  the  cervix  not  admitting 
the  finger,  subinvolution  is  probably  present,  and  by  massage  it  may  be  possible  to 
get  the  organ  to  contract.  Between  placental  polyp  and  partial  inversion  of  the 
uterus  the  combined  manipulation  must  decide,  and  it  is  usually  easy  if  the  latter 
condition  is  thought  of. 

Prognosis. — Even  though  severe,  the  hemorrhage  is  seldom  fatal,  and  it  re- 
sponds quickly  to  treatment.  The  most  dangerous  are  the  cases  of  placental 
polyp,  the  frequently  repeated  hemorrhages  depressing  the  puerpera  a  great  deal, 
and  especially  critical  are  the  infected  placental  fragments,  because  if  it  is  necessary 
to  remove  them,  the  unavoidable  manipulations  grind  the  infection  into  the  pla- 
cental site,  into  the  open  veins,  and  into  the  thrombi  here,  pyemia  easily  resulting. 

Treatment. — Early  in  the  puerperium  it  is  dangerous  to  submit  the  patient  to 
active  local  treatment,  especially  if  she  has  fever.  A  mild  infection  may  thus 
be  changed  to  a  fatal  one.  Therefore  external  remedies  are  at  first  to  be  tried. 
Ergot  and  hydrastis  internally,  massage  of  the  uterus,  and  the  ice-bag  or  a  hot 
vaginal  douche  may  be  ordered.  If  the  hemorrhage  persists,  the  uterovaginal 
tract  may  be  packed  with  slightly  antiseptic  gauze.  This  will  care  for  a  hemorrhage 
from  atony  as  well  as  one  from  the  retention  of  a  piece  of  placenta — indeed,  it  favors 
the  separation  and  expulsion  of  the  latter.  Manual  or  instrumental  curetage  is  not 
to  be  performed  in  the  early  puerperium.  It  is  best  to  temporize,  if  possible,  using 
frequent  tamponade,  rest,  medicine,  etc.,  until  the  fifth  or  sixth  week  of  the  puer- 
perium, by  which  time  involution  is  so  well  along  that  the  uterine  muscle  will  not  be 
easily  perforated,  and  the  blood-vessels  so  tightly  thrombosed  that  the  finger  or  the 
curet  will  not  be  able  to  carry  infection  into  them.  I  have  seen  two  fatal  infections 
result  from  neglect  of  this  advice.  Should  the  indication  to  remove  the  mass  be 
positive,  the  placental  forceps  and  the  finger  are  to  ])e  used,  not  the  curet;  an  anti- 
septic uterine  douche  precedes,  and  a  weakly  antiseptic  uterine  pack  completes,  the 
the  operation. 

A  retroverted  uterus  is  to  l)e  rei)laced  by  posture  or  the  colpeurynter,  not  by 
'the  fingers,  early  in  the  puerperium.  Later  a  pessary  may  be  api)Iied.  Myomata, 
cancer,  erosions,  etc.,  are  trcuited  on  gencn-al  principles.  Temporary  tamponade  of 
the  vagina  may  tide  the  patient  along  until  the  best  time  for  operating  arrives. 


POSTPARTUM    HEMORRHAGE  793 


SYNCOPE  AND  SUDDEN  DEATH  IN  LABOR 

A  gravida,  a  parturient,  or  a  puerpera  may  collapse  and  die  suddenly,  the  cause 
being  sometimes  determinable  only  at  the  autopsy.  Often,  however,  the  complica- 
tion may  be  expected,  knowing  previous  disease  to  exist.  Only  a  partial  enumera- 
tion of  the  causes  may  here  be  attempted,  otherwise  we  would  have  to  cover  the 
entire  field  of  medicine.  The  causes  may  be  divided  into- — (a)  Those  which  may  be 
properly  said  to  accompany  the  puerperal  state;  and  (h)  those  which  are  extra- 
genital, but  in  which  the  performance  of  the  reproductive  function  is  the  exciting 
factor.      (See  E.  P.  Davis.) 

A.  (1)  Sudden  collapse  and  death  may  be  due  to  hemorrhage  and  shock  from 
any  of  the  obstetric  accidents  already  discussed,  for  example,  ruptured  ectopic 
gestation,  placenta  previa,  abruptio  placentae,  rupture  of  the  uterus,  postpartum 
hemorrhage,  inversio  uteri,  rupture  of  the  pelvic  joints,  rupture  of  a  varix  in  the 
broad  ligament. 

(2)  The  acute  toxemias  which  go  with  the  pregnant  state,  the  prostration  and 
collapse  of  hyperemcsis  gravidarum,  the  toxemia  of  eclampsia,  of  pernicious  anemia, 
uremia  (Striimpell,  Bartels),  and  those  of  sepsis.  Almost  fatal  syncope  from  acute 
uremia  or  from  acute  pregnancy  toxemia,  with  characteristic  urinary  findings,  I 
have  observed  twice.  Zweifel  reported  such  a  case,  confirmed  at  autopsy,  and  Norris 
another.  Eclamptic  toxemia  may  cause  sudden  death  by  cerebral  hemorrhage,  and 
this  may  occur  when  the  convulsions  and  other  signs  of  the  disease  are  absent. 
Syncopal  attacks  in  severe  sepsis,  due  to  passing  cardiac  weakness,  are  common,  and 
the  end  in  such  cases  is  often  due  to  paralysis  of  the  heart,  which  ma}^  come  on 
suddenly. 

(3)  Pulmonary  embolism  is  an  often  mentioned  cause,  the  clot  usually  being 
found  plugging  one  or  more  of  the  pulmonary  arteries.  The  embolus  almost  always 
comes  from  the  thrombosed  veins  in  the  pelvis  or  thigh.  Slowing  of  the  circulation 
in  the  veins  allows  the  blood-platelets  to  accumulate  on  the  wall  and  build  a  white 
throml)us,  on  which  the  red  clot  will  always  be  found.  Alteration  of  the  blood  may 
predispose  to  thrombus  formation,  especially  if  the  vessel-wall  is  injured.  It  is 
possible  that  clots  may  form  in  the  large  veins  of  the  thigh  if  the  limbs  are  held  in  a 
cramped  position  for  a  long  time,  as  in  protracted  operations  with  the  patient  in  the 
exaggerated  lithotomy  or  Trendelenburg  positions.'  Puerperal  infection  acts  in 
two  ways,  first,  by  an  alteration  of  the  blood,  predisposing  to  thrombi  distant  from 
the  site  of  the  disease,  and  second  the  infection  may  spread  along  the  veins  or  to 
the  veins,  directly  causing  thrombosis.  Although  most  authors  emphasize  the 
mechanical  factors,  the  precipitation,  the  agglutination,  etc.,  I  have  never  seen  a 
thrombosis  where  infection,  either  endogenic  or  exogenic,  could  be  ruled  out. 
Thrombosis  may  follow  as  the  direct  result  of  an  intestinal  infection.  In  cases  of 
severe  anemia  or  profound  shock,  the  circulation  in  the  heart  being  almost  in 
abeyance,  a  clot  may  form,  and,  after  a  few  days  of  only  partial  recover}-,  sudden 
death  from  cardiac  paralysis  may  occur.  Pus  from  a  pelvic  abscess  may  break 
into  a  vein  and  reach  the  heart. 

Air-embolism  has  frequently  been  given  as  a  cause  of  sudden  death  in  preg- 
nancy and  labor.  A  colleague  of  the  author  told  of  a  woman,  pregnant  four 
months,  who,  while  taking  a  douche  with  a  bulb  s>Tinge,  died  suddenly  from  this 
cause.  Such  deaths  have  been  reported  from  attempts  to  produce  abortion  by  in- 
jecting air  into  the  uterus.  During  obstetric  operations,  especially  with  placenta 
previa,  the  accident  has  time  and  again  occurred.  Curiously  enough,  experiments 
on  animals  have  shown  that  enormous  quantities  of  air  can  be  injected  into  the  veins 
leading  directly  to  the  heart,  without  any,  or  quickly  passing,  bad  sj-mptoms  (Fitz- 
patrick).  'In  the  human,  however,  the  danger  of  the  admission  of  air  into  the  veins 
through  the  uterine  sinuses  is  a  well-established  fact.     During  the  operation  of 


794  THE    PATHOLOGY    OF   LABOR 

uterine  tamponade  in  placenta  pra^via  the  author  had  one  case  of  collapse  from  air- 
embolism  (recoverj').  In  personal  communications  Dr.  Skeel  and  Dr.  Bogardus 
report  two  others,  one  of  which  was  fatal.  Vavra  reports  a  fatal  one.  Gases  of  de- 
composition which  accumulate  in  the  uterus  may  gain  entrance  to  the  veins.  The 
Bacterium  aerog(Mics  capsulatus  has  been  found  in  these  cases,  and  the  presence  of 
such  gases  may  bring  tiie  diagnosis  into  question. 

(4)  The  nervous  shock  of  labor  may  cause  sjTicope  and  even  death,  and  a 
psychic  shock  at  the  time  of  labor  may  be  fatal.  In  the  First  Book  of  Samuel,  Ch. 
iv:19,  20,  it  is  said  that  Eli's  daughter,  learning  that  her  husband  and  father-in- 
law  were  killed  and  the  ark  of  God  taken,  went  into  \ahor  and  died.  Hirst  tells  of  a 
widow,  illegitimately  pregnant,  who,  on  being  shown  the  child,  went  into  delirium 
and  died.  Sue  (Histoire  des  Accouchements)  relates  that  a  pregnant  woman  was 
told  by  a  gJT^sy  that  she  would  die  in  labor.  She  made  her  will  and  expired.  Wil- 
liams had  a  similar  experience,  but,  by  giving  morphin,  he  put  the  woman  asleep, 
during  which  time  she  forgot  her  obsession.  That  profound  nervous  influences  can 
produce  postpartum  hemorrhage  I  am  convinced  from  actual  exjDerience.  Acute 
delirium  in  labor,  the  result  of  excessive  pain  in  a  nervously  disposed  individual,  may 
be  an  indication  for  the  termination  of  labor.  Loss  of  consciousness  may  occur 
during  the  second  stage,  the  result  of  intense  pain,  and  the  child  may  be  delivered 
without  the  knowledge  of  the  mother.  I  have  observed  this  myself,  and  agree  with 
Freyer  that  in  medicolegal  cases  cognizance  should  be  taken  of  it  as  a  fact — for  ex- 
ample, in  cases  where  a  mother,  bearing  alone,  is  accused  of  infanticide.  Syncope 
after  delivery,  in  the  absence  of  hemorrhage,  rupture  of  the  uterus,  etc.,  is  very 
rare,  and  may  be  due  to  nervous  or  physical  shock  in  susceptil)le  individuals.  I  have 
seen  s>mcope  follow  the  delivery  of  the  child  in  a  case  where  the  woman  had  been  en- 
forced to  breathe  very  rapidly  and  deeply  with  a  view  of  preventing  her  making  bear- 
ing-down efforts,  the  object  of  the  same  being  to  keep  the  child  back  until  the 
accoucheur  could  get  to  the  bedside.  This  phenomenon  is  probal^ly  an  acapnia. 
Traction  on  the  uterine  ligaments  b}'  forced  delivery  through  an  unprepared  par- 
turient canal  may  produce  peritoneal  shock.  I  have  seen  the  same  during  the 
removal  of  gauze  used  for  packing.  Sudden  loosening  of  a  Momburg  belt  may  be 
followed  by  syncope. 

Anderson  and  Roscnau  try  to  find  a  connection  between  the  admixture  of  fetal 
to  maternal  blood  and  eclampsia,  a  sort  of  anaphylaxis.  While  the  idea  is  not 
proved  for  eclampsia,  some  cases  of  collapse  and  sudden  death  postpartum  resemble 
certain  forms  of  anaphylaxis.  The  status  thymicus  has  not  been  studied  in  this 
connection. 

Acute  dilatation  of  even  a  normal  heart  may  occur  at  the  end  of  a  protracted 
second  stage,  with  exhaustive  bearing-down  efforts. 

Faintness  or  even  real  syncope  may  occur  when  a  puerpera  gets  out  of  Ijed  for 
the  first  time.  Formerly,  w^hen  puerperse  were  kept  in  the  horizontal  position  for 
many  days,  such  accidents  were  commoner  than  now,  when  more  activity  in  the 
lying-in  period  is  allowed. 

B.  Sudden  death  may  be  due  to  causes  which  have  indirect  comiection  with 
the  parturient  function — for  example,  heart  disease,  especially  mitral  stenosis  and 
myocarditis,  hydropericardium,  adhesive  pericarditis,  hydrothorax,  displacement  of 
the  heart  and  lungs  in  kyphoscoliosis,  struma  with  acute  strumitis,  etc.  The  strain- 
ing of  labor  may  rupture  the  heart,  the  spleen,  the  aorta,  the  splenic  or  mesenteric 
veins,  the  gut,  the  gall-bladder  (Rics),  peritoneal  adhesions,  or  a  Avalled-off  abscess 
(appendix  or  tube),  and  cause  collapse  and  speedy  death.  The  same  may  be  said  of 
rupture  of  a  blood-vessel  in  the  brain,  of  the  bronchioles  of  the  lung  with  emphysema 
(very  exceptional  as  a  cause  of  death  alone),  of  hemoptysis,  of  hemorrhage  into  the 
stomach  from  gastric  ulcer.     Brain  diseases,  tumor,  abscess,  thrombosis  of  the 


POSTPARTUM    HEMORRHAGE  795 

sinuses,  and,  finally,  poisoning  by  drugs  or  antiseptics,  chloroform,  morphin,  sco- 
polaniiii,  l)ichlorid,  iodoform,  carljolie  acid,  lysol — must  be  mentioned. 

Symptoms. — These  depend  on  whether  the  death  is  cerebral,  pulmonary,  or 
cardiac,  and  the  underlying  cause  will  determine  which  one  occurs.  Pulmonary 
embolism  with  cardiac  death  is  the  most  frequent  form.  The  patient  falls  as  if 
struck,  cries  once  with  pain  over  the  heart,  gasps  for  air,  becomes  cyanotic,  develops 
edema  of  the  lungs  with  blood}'  expectoration,  and  dies  in  a  few  minutes.  Some- 
times one  attack  passes  over,  or  the  woman  may  have  several  mild  ones,  but  usually 
the  second  or  third  is  fatal.  Between  attacks  cyanosis,  dyspnea,  fast  heart,  dilata- 
tion of  pupils,  nervous  excitation,  with  fear  of  impending  dissolution,  are  more  or 
less  marked.  If  the  embolus  is  small,  it  may  pass  on  into  the  lungs  and  the  patient 
may  recover.  ]Mild  symptoms  of  shock,  Avith  pain  on  the  affected  side,  bloody 
expectoration,  and,  locall}^,  perhaps,  a  friction-sound,  will  enable  one  to  make  the 
diagnosis.  The  embolus  may  pass  through  an  open  foramen  ovale  into  the  general 
circulation.  Fever  of  a  mild  tj^pe  almost  always  precedes  the  occurrence  of  the 
eml)olism,  and  experience  shows  that  women  with  varicosities,  with  myomata,  and 
those  on  whom  operations  near  the  veins  have  been  performed,  are  oftenest  stricken. 
Infection,  however,  is  accountable  for  the  majority  of  cases.  Mahler  believed  to  have 
proved  that  a  regularly  increasing  frequency  of  the  pulse  indicates  thrombosis  in  the 
veins.  I  cannot  confirm  it.  In  air  embolism,  on  the  occasion  of  local  interference,  the 
patient  goes  into  collapse,  breathing  becomes  difficult,  she  has  sharp  precordial  pain, 
and  in  three  to  ten  minutes  expires.  In  one  case  I  oliserved  a  severe  chill  with  the 
pulmonary  and  cardiac  symptoms,  followed  bj'  profuse  sweating.  Skeel,  in  his 
case,  heard  "tj^Dical  churning  noises"  over  the  heart,  and  J.  Y.  Simpson  refers  to 
a  reddish  sufTusion  of  the  cheeks.  At  autopsy  in  such  cases  the  heart  and  pul- 
monary vessels  arc  filled  with  frothy  blood,  and  death  is  due  to  heart  parah'sis — it 
cannot  pump  such  a  mixture.  Perhaps  the  coronary  vessels  are  sometimes  plugged 
with  an  air-embolus  which  acts  just  like  any  other,  the  clinical  picture  now  resem- 
bling angina  pectoris. 

Diagnosis. — AYhen  a  woman  faints  or  collapses  after  delivery,  the  accoucheur 
should  rapidly  review  the  course  of  the  labor  for  signs  of  any  of  the  following  condi- 
tions: Postpartum  hemorrhage,  rupture  of  the  uterus,  inversion  of  the  uterus,  intra- 
peritoneal hemorrhage,  excessive  operative  traumatism.  Next,  uremia  and  toxemia 
must  be  considered,  then  heart  and  lung  diseases.  Emboli  are  commoner  in  the 
puerperium.  True  syncope  and  shock  can  be  diagnosed  onh*  by  exclusion.  Post- 
anesthetic collapse  must  always  be  borne  in  mind.  Chloroform  is  the  most  danger- 
ous in  this  regard,  and  the  amount  administered  need  not  be  large,  especially  if  the 
woman  had  any  slight  latent  kidnej',  heart,  or  liver  disease.  Late  chloroform  death, 
due  to  fatt}'  degeneration  and  cytolj'sis  of  the  liver,  kidneys,  and  heart,  may  occur 
from  a  few  hours  to  twelve  days  after  delivery.  It  resembles  acute  yellow  atrophy 
of  the  liver,  with  delirium,  coma,  jamidice,  and  cardiac  paralysis.  It  may  be  very 
acute,  terminating  fatally  within  twelve  hours  (author's  case). 

Treatment  is  on  general  lines,  and  depends  on  the  diagnosis. 

Trendelenburg,  for  pulmonary  embolism,  advised  exposure  of  the  vena  pul- 
monalis  and  extraction  of  the  clot.  Four  cases  are  on  record,  all  fatal,  though 
Klein  states  two  might  possibly  have  been  saved. 

An  attempt  should  be  made  to  prevent  air-embolism  when  operating  or  moving 
the  patient.  In  packing  the  uterus  a  large  vent  should  be  left  alongside  the  hand. 
Sometimes  the  chance  must  be  taken. 


DELIVERY  OF  THE  FETUS  POSTMORTEM 

About  100  cases  of  spontaneous  delivery  of  the  child  after  death  of  its  mother  are 
on  record.     The  expulsion  of  the  fetus,  which  may  occur  within  six  or  more  hours> 


796  THE    PATHOLOGY    OF   LABOR 

or  after  days,  depending  on  the  cause,  is  usually  produced  by  the  gases  of  decomposi- 
tion in  the  intestines,  but  it  may  be  accomplished  by  gases  in  the  uterus  itself,  or 
even  bj^  contractions  of  the  uterus  postmortem.  In  such  cases  labor  had  begun  be- 
fore death,  and  the  parts  were  thus  prepared  for  delivery.  Outside  of  the  scientific 
interest  of  these  cases,  they  are  important  in  a  medicolegal  sense,  since  the  attending 
accoucheur  may  be  accused  of  criminal  neglect,  or  even  of  having  permitted  the 
burial  of  the  woman  alive.     (See  Reiman.) 


INFECTION  DURING   LABOR 

A  temperature  of  100°  to  100.6°  F.  may  frequently  be  found  toward  the  end  of 
the  second  stage  of  labor.  It  is  usually  ascribed  to  the  muscular  exertion,  to  absorp- 
tion of  fibrin  ferment,  excitement,  etc.,  but  the  author  believes  they  are  due  to  the 
absorption  of  toxins  from  the  parturient  canal.  Infection  during  labor  may  be  car- 
ried over  from  the  pregnancy,  from  coitus,  self-examinations,  etc.,  or  it  may  result 
from  instrumental  interference  (colpeurynters,  gauze,  etc.),  or  it  may  be  purely 
endogenic.  If  the  membranes  have  been  open  a  long  time,  bacteria  may  wander 
upward.  Warnekros  has  shown  that,  if  the  placental  circulation  is  in  action, 
bacteria  from  the  interior  of  the  uterus  easily  pass  into  the  blood. 

The  symptoms  of  infection  during  labor  are  the  same  as  those  at  any  other  time. 
The  child  is  endangered — it,  too,  may  become  diseased.  I  have  seen  a  pneumo- 
coccus  infection  thus  conveyed,  also  gonorrheal  ophthalmia.  The  liquor  amnii  is 
usually  discolored  and  odorous,  depending  on  the  kind  of  the  bacterium,  and  the 
Avounds  around  the  introitus  and  cervix  are  often  covered  with  grayish  exudates. 
Pus  may  issue  from  the  genitals.  When  fever  begins,  the  pains  are  usually  strength- 
ened, but  unless  delivery  is  soon  accomplished,  gas  develops  in  the  uterus  and  paraly- 
sis w^ith  distention  results. 

Treatment. — If  the  uterovaginal  canal  is  prepared  for  delivery,  this  may  be  per- 
formed at  once.  If  not,  the  accoucheur  may  well  hesitate  to  force  the  birth,  be- 
cause of  the  danger  of  making  extensive  injuries,  into  which  the  infection  will  be 
literally  ground.  The  greatest  danger  exists  in  the  presence  of  an  invasive  strepto- 
coccus. It  is  wdser  to  await  the  spontaneous  termination,  at  least  until  the  head 
comes  doAvn  onto  the  perineum,  interfering  only  when  absolutely  necessary.  Before 
such  operation  the  parts  are  to  be  carefully  douched  with  0.75  per  cent,  solution  of 
tincture  of  iodin.  It  is  my  practice  in  such  cases  not  to  suture  lacerations,  but  to 
leave  them  wide  open  for  drainage.  I  often  pack  the  whole  parturient  canal  lightly 
with  0.5  per  cent,  lysolized  gauze.  Some  authors  advise  not  to  put  the  hand  up  into 
the  uterus,  since  this  may  carry  the  infection  to  the  placental  site,  advice  which 
may  be  heeded  if  the  conditions  of  the  case  are  favorable.  A  chill  with  sharp  rise  of 
temperature  often  follows  operation,  but  the  fever  usually  subsides  in  twelve  hours 
unless  the  streptococcus  was  causative.

CHAPTER  LXII 
ACCIDENTS  TO  THE  CHILD 

Ideal  obstetrics  demands  that  every  child  not  congenitally  deformed  be  de- 
livered alive  and  absolutely  uninjured.  This  ideal  is  far  from  being  realized.  Sta- 
tistics show  that  over  4  per  cent,  of  the  children  die  during  birth.  Schultze,  in  1877, 
estimated  that  5  per  cent,  of  children  arc  still-born,  and  1.5  per  cent,  die  very  shortly 
after  birth,  the  result  of  the  trauma  of  labor.  A  large  percentage — how  large  it  is 
impossible  to  say — is  more  or  less  injured,  and  this,  too,  in  so-called  normal  delivery. 
Any  one  performing  autopsies  on  new-born  children  will  be  struck  by  the  frequency 
of  hemorrhages,  punctate  and  larger,  in  the  brain,  in  the  larger  ganglia,  along  the 
sinuses  and  the  sutures.  It  is  certain  that  such  extravasations  leave  scars,  per- 
haps minute,  in  the  cerebral  structures,  which  may  explain  some  cerebral  symptoms 
later  in  life. 

The  greatest  danger  which  besets  the  child  on  its  way  into  the  world  is  the  in- 
terruption of  its  respirator}^  function.  It  often  comes  in  a  condition  of  partial  or  com- 
plete anaerosis.  The  old  and  universally  used  term  toexpress  this  state  is  "asphyxia," 
but  this  is  etymologically  incorrect,  because  it  means  "without  pulse"  (from 
a-  o-0u^ts),  and  the  children  are  not  so  at  all — the  pulse  being  the  last  to  disap- 
pear. Numerous  terms  have  been  suggested  to  take  the  place  of  the  generally  and 
long-recognized  inappropriate  "asphyxia,"  such  as  dysapnea,  euapnea,  ecchysis 
pneumocardia,  anhematosis.  The  one  here  suggested  by  the  author,  anaerosis, 
from  a,  privative,  ai)p,  air,  and  -osis,  the  condition  of,  expresses  the  state  of  the  child 
and  covers  practically  all  the  causes.  In  the  succeeding  pages  the  two  terms, 
anaerosis  and  asphyxia,  and  their  derivatives,  will  be  used  synonymously,  or  as 
indicating  that  the  former  leads  to  the  latter. 


ASPHYXIA  NEONATORUM 

As  pregnancy  nears  the  end  the  fetus'  blood  ])ecomes  more  and  more  venous, 
which  is  due  to  the  gradual  narrowing  of  the  ductus  Botalli  and  ductus  Arantii. 
It  is  generally  said  that  the  fetus  cannot  stand  a  sudden  increase  of  this  venosity  as 
well  at  term  as  earlier  in  pregnancy,  but  my  own  experience  does  not  confirm  such  a 
statement.  From  Hippocrates'  time  a  popular  notion  has  prevailed  that  seventh 
month  l)abies  are  more  likely  to  live  than  those  of  the  eighth  month,  and  probably 
this  idea  is  founded  on  the  possible  greater  tolerance  of  asphyxia  by  fetuses  of  the 
earlier  months  of  pregnancy. 

The  child  exists  in  a  state  of  apnea,  that  is,  without  respiration,  because  it  has 
enough  oxygen  for  its  wants.  Observation  of  the  fetus  at  cesarean  sections,  and  of 
the  foot  or  arm  in  the  intact  ])ag  of  waters,  shows  a  slight  bluish  tint  of  the  skin, 
which  would  indicate  that  there  is  a  slight  increase  of  CO.,  over  that  of  the  delivered 
child.  The  fetus,  therefore,  is  not  in  a  state  of  acapnia.  During  labor  there  is  a 
gradually  increasing  anaerosis,  which  reaches  its  acme  just  as  the  head  is  expelled 
through  the  vulva.  With  each  pain  there  is  a  slight  retardation  of  the  maternal 
])lood-currcnt  through  the  placenta,  and  at  the  same  time  a  very  slight  increase  of 
pressure  on  the  fetal  head,  if  the  latter  has  already  entered  the  pelvis.  After  the 
bag  of  waters  has  ruptured  both  conditions  are  more  marked,  and  as  the  head  passes 
the  vulva  the  greatest  change  takes  place,  that  is,  the  head  suffers  the  greatest 

797 


798  THE    PATHOLOGY    OF   LABOR 

pressure,  the  uterus  contracts  the  hardest,  forchig  the  maternal  blood  out  of  its 
meshes,  and,  in  addition,  the  placental  site  undergoes  slight  reiluction  in  size  and 
there  maj'  be  some  detachment  of  the  placenta.  All  these  factors  have  a  positive, 
sometimes  marked,  influence  on  the  child.  In  the  first  stage  of  labor  they  usually 
cause  a  slight  slowing  of  the  fetal  pulse.  Seitz  finds  the  opposite — a  slight  increase 
of  rapidity.  In  the  second  stage  the  slowing  is  the  rule,  and  at  the  very  end 
it  is  invariable,  a  fact  easily  proved  by  palpating  the  chest  of  the  child  still  in 
the  vagina,  or  the  cord  directh'  after  birth.  When  born,  the  child  is  in  a  state  of 
slight  anaerosis,  or  if  the  second  stage  was  not  prolonged,  only  apneic.  As  a  result 
of  the  slight  pressure  which  the  head  undergoes  the  ])lood  is  forced  out  of  the  head, 
and  a  moderate  degree  of  anemia  of  the  base  of  the  l)rain,  the  medulla  included,  en- 
sues. The  slowing  of  the  maternal  Ijlood-strcam  and  the  changes  at  the  placental 
site  cause  a  mild  deoxidation  and  hj^jercarbonization  of  the  fetal  blood,  and  the 
anemia  of  the  medulla  accentuates  the  general  lack  of  oxygen.  Together  the  result 
is  that  the  cardiac  and  respiratory  centers  in  the  medulla  do  not  receive  good  blood. 
Since  the  respirator}^  center  is  naturally  torpid,  almost  inactive,  it  responds  very 
slowly  and  late  to  this  condition,  but  the  cardiac  center,  the  origin  of  the  vagus,  the 
pneumogastric,  is  very  sensitive,  and  the  deoxygenated  and  hypercarbonized  blood 
stimulates  it  to  action.  The  same  is  true  of  the  vasomotor  centers.  The  heart  is  de- 
pressed, the  pulse  is  slowed,  and  the  blood-pressure  slighth'  raised.  Whether  it  is 
the  lack  of  oxygen  or  the  excess  of  CO2  which  irritates  the  vagus  center  and  slows  the 
pulse  was  much  discussed.  Later  experiments  seem  to  prove  that  it  is  the  excess  of 
CO2.  If  the  anaerosis  is  acute,  the  stimulation  of  the  vagus  center  is  strong,  the 
heart  is  very  much  slowed,  and  the  asphj^xia  is  increased. 

Now  the  respiratory  center  awakens  and  elicits  spasmodic  contraction  of  the 
muscles  of  respiration.  The  fetus  gasps,  and  whatever  lies  near  its  mouth  is  sucked 
into  the  lungs — liquor  amnii,  vernix  caseosa,  meconium,  blood,  vaginal  mucus,  feces, 
etc.  This  inspiration  also  dilates  the  capillaries  of  the  lungs,  and  unless  there  is 
something  in  the  alveoli  (air)  to  exert  counterpressure,  some  of  the  capillaries  may 
burst.  As  a  fact,  smaller  and  larger  hemorrhages  in  the  lungs  and  pleurae  are  the 
rule  in  cases  of  asphyxiation.  If  the  loss  of  oxygen  and  increase  of  CO2  are  very 
slow,  the  respiratory  center  may  be  benumbed  and  the  fetus  may  die  without  having 
made  any  attempt  at  respiration.  These  cases  ofTer  a  bad  prognosis,  even  if  the 
child  is  delivered  with  the  heart  still  locating.  The  continued  stimulation  of  the 
vagus  center  results  finally  in  its  paralysis,  its  inhibitor}'  action  is  gone,  the  pulse 
jumps  to  180  to  200  or  more.  Sometimes  the  fetal  heart  becomes  irregular,  a  few 
powerful  beats  succeeding  a  run  of  weak,  almost  uncountable  pulsations.  In  other 
cases  of  threatened  intra-uterine  asphyxia  the  fetal  heart-tones  are  very  rapid  from 
the  start — 180  to  210.  It  is  possible  that  such  frequencies  are  preceded  by  slowing 
of  the  pulse,  though  in  several  cases  in  which  the  heart-tones  were  carefully  noted 
the  latter  was  not  observed.  It  is  hard  to  explain  the  primary  acceleration  of  the 
pulse,  though  perhaps  cerebral  compression  may  do  it  (Schroder).  Why  compres- 
sion of  the  l)rain  should  slow  the  heart  in  one  instance  and  hurry  it  in  another  is  not 
understood.  Direct  irritation  of  the  cortex  can  stimulate  the  cardiac  and  respira- 
tory centers,  and  peripheral  irritants  maj'  act  likewise.  It  is  possible  that  some  of 
the  irregular  phenomena  observed  during  labor  may  be  explained  in  this  way. 

Etiology. — Death  of  the  fetus  during  pregnancy  may  be  due  to  a  great  variety 
of  causes,  though  interference  with  the  function  of  respiration  is  found  in  the  last 
analysis  of  nearly  all  of  them.  All  the  acute  infectious  diseases,  especially  if  com- 
bined with  high  fever;  chronic  infections,  syphilis,  tuberculosis;  poisoning  by 
eclamptic,  uremic,  or  other  toxemic  poisons,  by  chemicals,  morphin,  phosphorus, 
etc.;  asphyxia  and  anemia  of  the  mother;  injuries  to  the  fetus  by  stab  or  blow; 
congenital  deformities;  diseases  of  the  fetus  itself,  as  leukemia,  sarcomatosis.  Buhl's 
disease,   heart  and  abdominal  affections;    all  these  and  more  like  them  ma}'  be 


ACCIDENTS   TO   THE    CHILD  799 

found.     Sudden  nervous  sliock  to  the  mother  may  kill  the  child  in  a  manner  not  yet 
explained. 

During  labor  the  causes  of  fetal  anaerosis  may  be  divided  into  two  classes: 
(1)  Those  which  directly  cut  off  the  supply  of  oxygen;  (2)  those  which  cause  com- 
pression of  the  brain. 

1.  Those  Cutting  Off  Oxygen  Supphj. — (a)  Prolonged  and  hard  labor  pains,  re- 
curring so  frequently  that  the  blood  in  the  placental  sinuses  cannot  be  renewed,  are 
the  most  common  factor.  This  is  observed  at  the  end  of  the  second  stage,  with 
rigid  pelvic  floor,  in  contracted  pelvis,  with  tetanus  uteri,  and,  but  rarely  nowadays, 
with  the  use  of  ergot.  The  general  mortality  of  the  children  in  protracted  labor 
increases  in  proportion  to  the  length  of  labor;  (6)  excessive  retraction  of  the  uterus 
away  from  the  child,  with  diminution  of  the  placental  area,  and  perhaps  with  some 
partial  separation  of  the  placenta,  for  example,  neglected  shoulder  presentation, 
threatened  ruptura  uteri;  (c)  compression  of  the  placentawhen  it  is  low  in  the  uterus, 
or  of  the  insertion  of  the  cord,  either  l)y  the  head  or  trunk,  or  sometimes  by  the  col- 
peurynter;  or  compression  of  the  placenta  by  the  head  when  the  child  presents  by  its 
breech;  (d)  compression  of  the  umbilical  cord,  either  with  prolapse  of  same  or  while 
it  still  lies  in  the  uterus;  coiling  of  cord  aroimd  the  neck  of  the  child  may  cause 
anaerosis,  and  here,  too,  it  is  especially  exposed  to  injurious  pressure  from  the  tip 
of  the  forceps  blade;  knots,  rupture,  hematoma  of  the  cord;  (e)  partial  and  com- 
plete abruption  of  the  placenta,  either  normally  or  abnormallj"  implanted,  in  either 
head  or  breech  presentations;  (/)  anemia  of  the  child  from  rupture  of  the  placental 
vessels  (placenta  praevia)  or  tearing  of  a  velamentous  vessel;  (g)  narcosis  (morphin), 
asphj'xia,  anemia  of  the  mother,  the  child  dying  first,  since  it  gives  back  oxj'gen  to 
its  mother. 

During  the  first  few  minutes  after  birth  the  child  ma}'  be  asph\'xiated  by  its 
air-passages  being  blocked.  A  tight  caul;  the  aspiration  of  vaginal  mucus,  blood, 
meconium,  or  the  mucus  which  often  lies  in  the  child's  o^mi  glottis  and  is  dra'^Ti  do\Mi 
by  the  first  breath;  edema  of  the  glottis  and  throat  consecutive  to  face  presentation; 
congenital  atelectasis  (sjiDhilis,  etc.);  heart  and  other  diseases;  gross  and  micro- 
scopic deformities — all  these  have  been  found  more  or  less  often. 

2.  Compression  of  the  brain  brings  about  asphyxia  in  several  ways,  depending 
partly  on  the  manner  of  compression,  whether  internal  or  external.  Internal  com- 
pression from  hemorrhage  or  fracture,  as  well  as  external  i^ressure  from  a  contracted 
pelvis,  may  slow  the  pulse  antl  cause  anaerosis,  because  the  blood  is  hindered  from 
reaching  the  placenta.  Internal  local  compression  of  the  cardiac  and  respiratory 
centers  may  cause  asphyxia  bj-  directly  paralyzing  the  vagus  or  stimulating  respira- 
tory action.  The  slowing  of  the  heart  from  cerebral  compression  can  be  easily 
demonstrated  during  forceps  operations  if  the  accoucheur  will  but  listen  while  he 
closes  the  blades  of  the  instrument.  In  some  cases  the  effect  is  not  immediate,  but 
it  is  always  present  if  the  pressure  is  kept  up  a  few  seconds  or  if  it  is  made  quite 
strong.  Sudden  and  marked  slowing  of  the  beat  is  proof  that  the  cord  has  been 
caught  in  the  grasp  of  the  blades.  It  is  probable  that  in  cases  of  cerebral  compres- 
sion without  hemorrhage  there  is  also  an  additional  external  cause  which  reduces  the 
amount  of  oxygen  in  the  fetal  blood  which  may  be  found  under  Class  1. 

Finally  may  be  mentioned  the  premature  respirations  made  bj'  the  child,  the 
result  of  external  stimuli,  version,  forceps,  pulling  on  the  leg  in  breech  extraction, 
and  the  presence  of  air  in  the  uterus.  Compression  of  the  vessels  in  the  neck  (face 
presentation,  coiling  of  the  cord)  produces  a  local  venous  congestion  of  the  brain. 

Pathology. — Postmortem  findings  vary,  of  course,  with  the  cause  and  the  rapid- 
it}'  of  the  asphyxia.  In  general  one  finds  the  effects  of  an  intense  venous  congestion 
combined  with  that  of  localized  spasm  of  the  arterioles.  The  auricles  of  the  heart, 
the  pulmonary  system,  the  liver,  and  the  spleen  are  engorged  with  blood.  The 
back  pressure  in  the  veins  of  the  lungs,  pleurae,  pericardium,  peritoneum,  brain, 
kidneys,  and  suprarenals  causes  extravasations  of  blood,  varying  in  size  from  a  pin- 


800  THE    PATHOLOGY    OF    LABOR 

head  to  one  inch,  and,  particularly  in  the  brain,  immense  hematomata  may  form. 
Minute  hemorrhages  in  the  retina,  the  ear,  and  in  the  ganglia  at  the  base  of  the 
brain  may  cause  serious  disturbance  of  function  if  the  child  withstands  the  primary 
asphyxia.  Serosanguineous  transudations  may  be  found  in  the  pericardium,  pleurae, 
peritoneum,  and  in  the  brain.  If  respiratory  movements  had  been  made,  liquor 
amnii,  meconium,  blood,  etc.,  may  be  found  in  the  lungs,  parts  of  which  are  ate- 
lectatic and  parts  full  of  air.  Seitz  emphasizes  the  importance  and  frequency  of 
edema  of  the  jircvesical  connective  tissue  around  the  hypogastric  arteries,  and  edema 
of  the  genitals,  particularly  of  the  scrotum.  Edema  of  the  vulva  and  scrotum  is 
not  rarel}^  observed  after  natural  labors,  and  Seitz  says  it  is  likewise  due  to  asphyxia. 
When  the  umbilical  cord  is  compressed,  the  back  pressure  is  felt  first  in  the  vein  and 
then  the  arteries  near  the  navel. 

Symptoms  and  Diagnosis. — Before  Delivery  of  the  Child. — 1.  The  most  im- 
portant, because  the  most  reliable,  external  evidence  of  danger  besetting  the  child 
in  utero  is  a  change  in  the  fetal  heart-sounds.  These  may  be  altered  as  to  fre- 
quency, regularity,  strength,  and  rhythm.  A  persistent  slowing  of  the  fetal  heart 
to  100  beats  a  minute  is  always  significant  of  clanger,  and  if,  during  the  uterine  con- 
traction, the  rate  goes  do^Mi  to  80  or  less,  there  is  no  dou])t  about  it,  and  delivery 
is  demanded  forthwith.  As  the  rate  sinks  from  the  usual  140-136  to  124-112,  then 
to  112-100,  the  two  rates  given  as  those  between  and  during  the  pains,  respectively, 
the  accoucheur  becomes  more  and  more  certain  that  there  is  some  factor  causing  a 
stimulation  of  the  vagus.  At  the  same  time  the  tone  becomes  stronger,  and  occa- 
sionally a  little  accentuation  of  the  second  sound  may  be  distinguished.  Prim- 
arily increased  rapidity  of  the  heart-tones  is  not  so  good  a  sign,  but  if  the  heart- 
tones  are  continuously  above  175  (Winckel  says  160),  without  fever  of  the  mother, 
danger  to  the  life  of  the  child  may  be  apprehended.  The  sudden  change  from 
slowed  heart-tones  to  excessive  rapidity  denotes  paralj^sis  of  the  vagus  center 
and  is  of  very  bad  omen.  As  a  rule,  at  this  time  the  respirator}^  center  awakens 
and  elicits  inspirations.  Irregularity  of  the  fetal  heart  is  also  significant.  A  few 
strong  beats  are  followed  by  a  run  of  light,  short  taps,  and  sometimes  the  heart 
may  run  and  stumble  along  in  a  most  erratic  manner.  This  irregularity  is  very 
ominous  if  it  follows  a  period  of  slowed  action.  Sometimes  the  rate  of  the  heart 
will  run  from  140  to  170  without  definable  cause  and  without  relation  to  the 
uterine  contractions.  It  is  wise  to  distrust  such  cases.  The  strength  of  the  tone 
gives  additional  information,  a  slow,  strong  sound  indicating  vagus  stimulation,  a 
rapid,  weak  one,  paralysis  or  general  fetal  weakness.  If  the  first  sound  of  the  heart 
is  booming,  a  healthy  muscle  may  be  diagnosed;  if  it  is  weak  and  valvular, 
gallop-rhythmus  being  present,  danger  exists.  In  general,  the  above  findings  are 
positive  of  threatening  danger,  but  in  rare  instances  most  of  them  maj^  be  present 
and  the  child  is  born  alive  and  well,  while  still  more  rarely  the  heart  may  show 
no  evidences  of  distress  and  yet  the  infant  is  still-born  or  asphyctic.  Cerebral 
hemorrhage  may  sometimes  do  this.  Other  signs  of  intra-uterine  anaerosis  will 
aid  the  accoucheur  here,  but  he  will  not  be  much  amiss  if  he  interferes  in  the  labor 
on  the  indication  given  by  a  study  of  the  fetal  heart-tones. 

(2)  The  passage  of  licjuor  anmii  stained  with  fresh  meconium  is  a  valuable  sign 
of  impending  intra-uterine  asphyxia.  It  was  the  only  one  the  ancients  had.  The 
sign  is  of  no  value  if  the  presentation  is  a  breech,  unless  the  latter  has  not  neared  the 
inlet.  The  passage  of  meconium  is  due  to  an  active  peristalsis  set  up  by  the  anacrotic 
blood,  and  finds  its  analogy  in  the  bowel  movements  of  drowned  or  otherwise 
asphyxiated  persons.  It  is  true  that  the  use  of  quinin  will  cause  the  discharge  of 
meconium,  and  that  in  a  certain  percentage  of  natural  deliveries  meconium  will 
come  away  in  the  liquor  amnii  and  the  child  will  show  no  evidences  of  distress  when 
born.  My  experience  and  Rossa's  agree,  that  the  character  of  the  labor  in  these 
cases  was  such  that  anaerosis  would  be  very  likely  to  occur.     While  I  am  willing  to 


ACCIDENTS   TO   THE    CHILD  801 

agree  that  the  sign  does  not  have  the  absolute  significance  that  some  writers  ascribe 
to  it  (Kiistnor),  I  am  inclined  to  give  it  more  value  than  does  Seitz  in  his  monograph. 

Liquor  aninii  stained  with  old  meconium  is  olive-green  in  color  and  the  mecon- 
ium is  thoroughly  mixed  with  it.  Fresh  meconium  is  dark  sea-green  and  is  lumpy. 
If  such  a  mixture  is  expelled,  the  accoucheur  should  study  the  fetal  heart-tones  and 
the  nature  of  the  labor,  and  if  any  cause  for  anaerosis  or  any  irregularity  of  the 
heart-tones  is  discovered,  the  sign  becomes  of  positive  value.  In  obstructed  labors 
the  passage  of  meconium  may  long  ])recede  the  slowing  of  the  heart. 

If  the  asphyxia  is  fairly  well  established,  the  cliild  makes  respiratory  movements 
and  these  may  be  seen,  felt,  or  heard  by  the  attendant.  (3j  During  breech  de- 
liveries one  may  see  and  feel  the  diaphragm  come  down;  during  forceps  operations 
it  is  often  possil)le  to  feel  and  see  the  gasps  of  the  child  as  jerks  of  the  forceps  or  as  a 
jarring  of  the  lower  abdomen.  It  may  be  impossiljle  to  distinguish  these  jerky 
gasps  from  fetal  hiccup.  The  fetal  heart-tones,  the  nature  of  the  labor,  and  the 
meconium  must  aid  in  the  differentiation.  Unless  the  child  can  be  extracted  within 
a  few  minutes  after  it  gasps  it  is  lost,  and  even  if  delivered  alive,  it  wdll  very  likely 
die  within  a  few  days  from  atelectasis  pulmonum  or  cerebral  hemorrhage. 

Vagitus  Uterinus. — This  term  has  been  applied  to  the  crying  of  the  child  in  utero — before 
it  is  born.  Many  authentic  cases  are  on  reconl.  It  is  said  that  Mahomet  and  St.  Bartholomew 
made  themselves  heard  while  in  the  uterus,  but  these  probably  are  fables.  If  air  is  introduced  into 
the  uterine  cavity  alongside  the  hand,  as  in  version,  or  with  instruments,  or  by  a  simple  examina- 
tion, or  if  gases  develop  there,  the  child  may  inspire,  and  on  expiration  may  produce  a  cr3^  Some- 
times this  may  occur  without  other  e\-idences  of  dyspnea,  and  the  child  may  be  delivered  in  good 
condition,  but  usually  the  condition  is  due  to  anaerosis,  and  unless  the  infant  is  at  once  delivered, 
it  will  suffocate.  In  Kristeller's  case  the  child  cried  8  different  times,  when  the  forceps  were  closed 
on  its  head.  From  a  medicolegal  point  of  view  the  cases  of  vagitus  uterinus  are  very  important, 
since  the  hmgs  may  be  partly  inflated  and  the  child  die  before  birth.  Finding  air  in  the  child's 
lungs  would  be  no  evidence  against  the  individual  accused  of  infanticide. 

Other  signs  of  threatening  intra-uterine  asphyxia  are:  (4)  Very  active  fetal 
movements,  felt  by  the  mother  or  by  the  attendant,  a  phenomenon  w^hich  occurs 
especially  if  the  anaerosis  is  sudden,  and  may  indicate  a  death-struggle  or  attempts 
to  respire;  (5)  the  persistence  of  a  loud  umbilical  souffle;  (6)  the  loss  of  tonus  of 
the  anus  in  breech  cases;  (7)  the  weakening  and  disappearance  of  the  pulse  in  a  foot 
or  hand  which  maj'  be  brought  down,  or  from  the  cord,  which  may  have  prolapsed. 
In  many  cases  I  have  passed  the  hand  into  the  uterus  to  feel  the  heart.  (8)  Pulsa- 
tion of  the  fontanel  is  not  discoverable,  but  in  one  case  I  could  feel  the  child's 
heart  through  the  thin  abdominal  wall. 

After  Delivery. — Cazeaux  defined  two  degrees  of  asphj'xia  in  the  new-born 
child — asphyxia  livida  and  asphyxia  pallida.  The  symptoms,  of  course,  depe^nd  on 
the  degree  of  the  anaerosis,  and  between  the  two  states  mentioned  there  are  many 
gradations. 

In  asphyxia  livida  the  child  is  dark  blue,  sometimes  purplish  and  mottled,  the 
face  swollen  and  congested,  the  eyes  somewdiat  prominent,  and  the  conjunctiviB 
injected;  the  skin  around  the  nose  and  mouth  may  be  slightly  pale,  but  the  lips  are 
deep  blue.  Tonus  of  the  muscles  is  not  lost;  the  arms  are  held  up;  the  bodj'  is 
fairly  rigid;  the  mouth  closes  on  the  finger;  the  throat  reacts.  If  the  face  is  blo'VN'n 
upon  or  wet  with  cold  water,  the  muscles  tA\'itch.  The  heart  and  cord  pulsate  slowly 
and  strongly;  there  is  an  occasional  gasp,  accompanied  by  a  gurgling  sound,  the 
mouth  and  bronchi  being  full  of  mucus.  These  are  the  mild  cases,  and  they  respond 
quickh'  to  treatment. 

In  asphyxia  pallida  an  entirely  different  aspect  is  presented.  The  child  is 
pale  and  waxy,  but  the  lips  alone  are  blue.  The  body  is  limp,  the  extremities  hang- 
ing down  without  any  tonus  at  all ;  the  jaw  drops  relaxed — the  throat  does  not  react. 
There  are  no  respiratory  movements,  or  a  rare  gasp  which  is  very  superficial  and 
may  be  simply  a  movement  of  the  jaw.  The  only  e\'idence  of  life  is  a  weak  and 
slow,  or  perhaps  very  rapid,  heart-beat.  This  may  not  be  palpable,  but  will  be 
51

THE    PATHOLOGY    OF    LABOR 


audible  with  the  stethoscope.  Tiie  cord  is  Hmp  and  collapsed ;  th(^  bahy  looks  like  a 
corpse.  The  criteria  of  this  severe  form  of  as))hyxia  are  the  absence  of  nuiscular 
tonus  and  the  loss  of  reflex  excitability.  This  condition  is  of  much  worse  prognosis, 
and  even  if  the  infant  is  revived,  it  may  die  later  of  secondary  asphyxia.  The  lung 
is  not  fully  inflated;  areas  of  atelectasis  exist  which  offer  great  resistance  to  the 
flow  of  lilood.  As  a  result  of  the  permanent  deoxidation  and  hypercarbonization  of 
the  blood  which  supplies  the  heart  muscle  this  organ  cannot  develoi)  sufficicuit  power. 
The  anaerosis  also  aliects  the  nerve-centers,  and  the  child  gradually  sinks  into  coma; 
the  respiration,  which  never  was  adequate  and  was  attended  by  a  grunt  or  whine, 
l^ecomes  more  and  more  superficial  and  rai:>itl,  finally  ceasing.  The  heart  continues 
to  act  for  a  while  through  its  own  automaticity,  but  soon  this  disappears.  At  the 
autopsy  hypostatic  edema  is  determined  in  addition  to  the  other  findings. 

Diagnosis. — Not  all  children  that  are  born  in  an  apparently  moribund  state 
are  asphyxiated.  Other  conditions  are  pressure  on  the  brain,  anemia,  apnea,  and 
morphin-poisoning.     Brain   compression  may  be  both  the  cause  and  the  result  of

asphyxia.  We  have  seen  how  it  can  cause  asphyxia.  In  cases  of  asphyxia  there  are 
great  cerebral  congestion  and  sometimes  spasm  of  the  arterioles.  The  thin-walled 
vessels  of  the  brain  may  burst,  causing  hemorrhage,  which  may  be  subdural,  sub- 
arachnoid, or  intraventricular.     This  in  turn  causes  anaerosis. 

The  diagnosis  of  cerebral  compression  is  not  easy,  and  the  character  of  the  labor 
must  be  the  guide,  e.  g.,  a,  hard  forceps  or  extraction,  in  which  it  is  known  that  in- 
juries to  the  skull  have  been  made.  Focal  symptoms  are  usually  absent  in  the  very 
early  stages.  In  some  cases  of  cerebral  hemorrhage  it  is  i)ossil)le  to  keep  the  heart 
going  for  manj^  hours  with  artificial  res]iiration,  l)ut  the  infant  cannot  l)e  made  to 
breathe.  The  treatment  must  be  like  that  of  asphyxia.  An  anemic  fetus  resembles 
one  with  pale  asphjrxia,  and  the  diagnosis  may  be  made  only  if  it  is  known  that  the 
infant  suffered  a  loss  of  blood,  as  from  tearing  of  the  placenta  when  it  is  ])rtrvia,  or 
rupture  of  a  velamentous  vessel. 

An  apneic  child  is  often  called  an  anacrotic  one,  and  frantic  (efforts  are  made 
to  get  it  to  breathe  when  only  a  few  minutes'  patient  waiting  is  all  that  is  required. 


ACCIDENTS   TO   THE    CHILD  803 

Such  an  occurrenco  is  frcqiuMit  at  cesarean  section.  In  apnea  the  child  looks  nat- 
vu-al,  the  lips  are  slightly  cyanotic,  the  features  are  not  distorted,  the  color  is  light 
grayish  blue,  the  heart-l)eat  is  strong  and  not  much  s1o\v(h1  at  first.  Gradually 
the  cyanosis  deepens,  the  pulse  slows,  the  child  becomes  anacrotic,  which  stimulates 
the  respiratory  center  or  prepares  the  center  for  the  reception  of  the  stimulus  from 
the  outside  air,  and  the  first  gasp  occurs,  or  a  sneeze  which  removes  the  mucus 
from  the  air-passages.  A  few  tiny  respirations  precede  the  gasp,  and  a  vigorous 
cry  follows  it. 

Morphin-poisoning  is  not  rare  under  the  use  of  scopolamin-morphin  anesthesia 
and  when  the  latter  drug  is  given  in  eclampsia.  The  child  is  very  quiet  and  limp, 
cyanotic,  the  pupils  contracted,  the  conjunctiva?  insensible,  but  the  heart-beat  is 
usually  strong,  regular,  and  not  v(ny  slow,  unless,  in  addition,  the  infant  is  asphyxi- 
ated. If  spanked,  the  child  opens  its  eyes  or  grimaces  with  pain,  but  does  not  cry 
nor  breathe.  Usually  there  is  no  mucus  in  the  air-passages.  Resuscitation  is  at 
first  successful:  the  child  may  be  brought  to  cry  or  even  to  open  its  eyes,  but  it 
soon  relaxes  into  somnolence  and  then  into  coma.  I  have  kept  such  an  infant  alive 
for  six  hours  until  finally  the  heart  gave  out. 

Prognosis. — It  is  naturally  impossible  to  form  a  true  estimate  of  the  frequency 
and  of  the  mortality  of  asphyxia  neonatorum,  since  there  is  no  standard  by  which 
the  severity  of  such  cases  may  be  measured.  In  general  it  may  be  said  that  the 
milder  and  shorter  the  asphyxia  is,  the  better  the  chances  of  immediate  and  per- 
manent recovery  are,  and  the  severer  and  more  prolonged  it  is,  the  more  dark  the 
prognosis.  It  has  been  found  that  many  children  die  from  the  effects  of  asphyxia  as 
late  as  the  fourteenth  day,  though  the  greatest  secondary  mortality  occurs  w^ithin 
forty-eight  hours.  Children  that  have  been  for  a  long  time  in  a  state  of  partial 
anaerosis  in  utero, — two  to  six  hours, — even  though  delivered  alive,  often  die  im- 
mediately or  shortly  after  birth.  This  fact  must  be  taken  into  consideration  when 
selecting  obstetric  operations.  Children  on  whom  efforts  of  resuscitation  had  to 
be  prolonged  to  bring  them  back  to  life  also  die  in  large  numbers  within  a  few  hours 
or  days,  simply  l^ecause  the  asphyxia  was  very  deep  and  fatally  damaged  vital 
structures.  Poppel,  in  18G5,  confirmed  these  daily  clinical  experiences  by  statistics. 
Asphyxiated  children  are  more  liable  to  infection,  to  bronchopneumonia,  in- 
testinal inflammation,  mela?na  neonatorum,  icterus,  hemorrhage  into  the  parathy- 
roids, with  spasmophilia  (Graham),  meningitis,  acute  and  chronic  atelectasis  pul- 
monum,  and  they  often  suff'er  from  the  effects  of  the  anaerosis — cerebral  and  other 
hemorrhages,  as  well  as  from  the  injuries  which  sometimes  are  inflicted  on  them 
with  too  violent  methods  of  resuscitation.  These  are  bruises,  burns,  fracture  of  the 
ribs  and  sternum,  blowing  foreign  matter  into  the  lungs,  rupture  of  viscera,  etc. 

Boys  die  from  asphyxia  in  a  greater  number  than  girls,  because  they  are  larger 
and  harder,  causing  dystocia  more  often.  Children  of  primiparse  suffer  from  it 
oftener  than  those  of  multipara.  Rigid  pelvic  floor  causes  a  high  infant  mortality. 
Asphyxia,  directly  due  to  operative  deliveries,  and  also  the  shock  to  the  fetus 
attending  the  same,  must  always  be  considered.  Of  great  interest  and  importance 
is  the  well-established  fact  that  children  that  w^ere  asphyxiated  or  brain-injured 
during  h'wth.  often  suffer  from  severe  psychic  and  nervous  diseases  later  in  life. 
Prolonged  lal)or  and  operative  deliveries  with  asphyxia,  com])ined  or  singly,  produce 
the  untoward  results — for  example,  spastic  cerebral  and  spinal  paralysis,  poren- 
cephalus  with  idiocy,  syringomyelia,  congenital  athetosis,  chorea,  epilepsy,  back- 
wardness, stuttering,  and,  the  author  would  like  to  add,  retinal  atrophy,  strabismus, 
and  nunital  aberration.  We  know  that  in  adults  concussion  of  the  brain  is  often 
followed  l)y  weakness  of  memory,  lack  of  concentration,  easy  fatigue,  emotionalism, 
susceptibility  to  alcohol,  traumatic  neuroses,  etc.,  and  it  is  not  illogical  to  assume 
that  the  tender  brain  of  the  new-born,  in  a  formative  state,  could  be  similarly 
affected  by  the  concussion  of  a  violent  delivery.     On  the  other  hand,  even  the

severest  cerebral  compression  and  prolongi^l  asjjhyxia  may  leave  no  traces  discover- 
able in  after-life.  Beach,  in  810  idiots,  found  a  history  of  hard  forceps  in  4  per  cent., 
and  in  26.6  per  cent,  spontaneous  but  difficult  labor.  Porter  states  that  17  per  cent, 
of  the  epilejitics  in  the  Indiana  School  for  Feeble-minded  had  a  history  of  difficult 
labors. 

Treatment  Before  Birth. — The  prevention  of  asphyxia  of  the  child  in  utero 
comprises  the  recognition  of  the  causes,  and  a  studied  avoidance  of  them,  which 
means,  in  short,  that  the  accoucheur  should  direct  the  course  of  labor  into  normal 
channels  and  interfere  only  when  really  necessary.  In  every  labor,  and  especially  if 
it  is  foreseen  that  the  child  may  be  anacrotic,  preparations  for  same  must  be  made. 
A  suitable  table  or  a  place  on  the  bed  is  arranged,  with  a  supply  of  warm  towels,  a 
hot-water  bag,  a  warm  bath  of  100°  to  110°  F.  (bath  thermometer !),  and  two  tracheal 
catheters  (Fig.  729).  These  are  No.  14  and  No.  15  (Fr.)  linen  catheters.  They 
may  not  be  boiled,  but  are  thoroughly  washed  inside  and  out  after  using,  then  im- 
mersed in  1 :  1000  bichlorid,  flushed  with  alcohol,  and  dried.     In  maternities  they 

may  be  sterilized  in  a  tall  jar  in  formal- 
dehyd  gas.  No  obstetric  satchel  is  com- 
plete without  tracheal  catheters.  The 
glass  bulb  sho^vn  in  the  illustration  is  a 
saliva  trap,  and  at  the  same  time  pre- 
vents mucus,  meconium,  etc.,  from  being 
drawn  into  the  operator's  mouth. 

At  an  interval  of  an  hour  or  oftener 
in  the  first  stage,  and  at  least  thirty  to 
fifteen  minutes  in  the  second  stage,  or 
even  every  five  minutes  if  the  delivery  is 
laborious,  the  fetal  heart-tones  should  be 
auscultated.  For  this  purpose  the  author 
uses  a  boiled  stethoscope,  or  has  an  assist- 
ant attend  to  it.  At  the  first  sign  of  fetal 
distress  redoubled  watchfulness  is  prac- 
tised, the  fetal  heart  listened  to  almost 
continuously,  and  preparations  for  oper- 
ative delivery  are  made. 

As  soon  as  the  fact  of  fetal  danger  is 
established  two  courses  of  treatment  are 
indicated — either  the  cause  of  the  anaero- 
sis  must  be  removed  or  the  child  be  gotten 
out  where  it  can  get  air.  If  the  pains  are 
too  strong  and  frequent,  preventing  the  change  of  blood  in  the  uterus,  ether  may 
be  given  to  quiet  them,  and  thus  allow  freer  circulation  in  the  placental  site;  a  pro- 
lapsed cord  may  be  replaced  or  otherwise  relieved  from  compression,  but  this  is 
about  all  we  can  do  to  aid  the  child  before  birth.  Kapid  delivery  offers  the  best 
hope,  but  it  may  not  always  be  possible,  and,  further,  often  the  operative  trauma 
itself  kills  the  infant.  Delicate  questions  are  here  involved,  and  the  principle  of 
-primum  nil  nocere  should  not  be  violated.  Broadly  speaking,  in  cases  of  threatened 
asphyxia  in  utero  the  child  should  be  delivered  as  soon  as  j)ossible,  having  due  re- 
gard— (1)  To  the  state  of  the  child  and  the  probability  of  its  being  gotten  out  alive 
and  of  living  afterward;  (2)  to  the  amount  of  injury  which  the  interference  will 
inflict  on  the  mother;  and  (3)  to  the  actual  danger  to  her  life  which  it  will  incur. 
Treatment  After  Delivery. — When  a  child  is  born  ai)parently  dead  it  is  of 
instant  importance  to  determine  if  the  asphyxia  is  mikl  or  severe,  because  in  the 
last  condition  no  time  may  be  wasted  on  inefficient  measures,  while  in  the  former 
the  simplest  remedies  are  usually  successful.     The  heart-beat,  the  presence  of  re-

sterilized  chemically  or  in  formaldehyd  vapor.

action  in  the  skin  and  throat,  and  the  degree  of  body  tone  will  enable  a  quick 
diagnosis.  Three  grand  principles  govern  the  treatment:  (1)  Clear  the  air-passages 
from  obstructions;  (2)  maintain  body  heat;  (3)  supply  oxygen  to  the  blood. 

The  importance  of  keeping  the  baby  warm  is  not  generally  appreciated.  The 
infant  is  wet;  exposure  is  often  prolonged;  evaporation  is  rapid;  the  body  temper- 
ature sinks  rapidly.  This  is  ver}'  depressing,  and  the  shock  of  delivery  is  thus  aug- 
mented— indeed,  it  has  occasionally  happened  that  the  infant,  wrapped  up  and 
put  away  as  dead,  has  recovered  through  the  influence  of  warmth  alone.  There- 
fore the  baby  should  be  received  in  warm  towels,  and  kept  covered  as  much 
as  possible  during  the 
subsequent  manipulations. 
Some  of  these  may  be  car- 
ried out  while  the  child  is 
in  a  warm  bath. 

The  first  duty  is  to 
clear  the  air-passages.  It  is 
dangerous  to  perform  arti- 
ficial respiration  when  the 
trachea,  bronchi,  and  some- 
times the  alveoli  are  full  of 
amniotic  fluid,  meconium, 
blood,  or  vaginal  secretions. 
These  must  be  removed  be- 
fore any  attempt  is  made  to 
l)ring  air  into  the  lungs, 
otherwise  the  foreign  sub- 
stances would  be  forced  still 
further  do^^^l  and  give  rise 
to  atelectasis,  pneumonia, 
and  sepsis. 

During  the  delivery,  as 
soon  as  the  child's  nose  and 
mouth  appear,  they  are 
wiped  with  pledgets  of  lin- 
tineor  soft  linen.  In  breech 
labors  one  of  the  fingers  in- 
troduced for  the  perform- 
ance of  the  Veit-Smellie 
manceuver  should  block  the 
glottis  to  prevent  the  gasp- 
ing infant  from  aspirating 
mucus,  blood,  etc.     In  head 

labors,  after  delivery  of  the  head,  while  clearing  the  phar\Tix,  two  fingers  gently 
strip  the  neck  toward  the  jaw  in  an  effort  thus  to  bring  inspired  matter  into  the 
throat.  It  is  important  to  dear  the  uppermost  air-passages  before  the  child  makes  the 
first  gasp.  In  the  mildest  cases  this  is  all  that  is  required,  because  the  irritation 
of  the  throat  excites  cough  and  respiration.  When  the  child  is  fully  delivered,  it 
is  held  up  by  the  ankles,  while  the  head  rests  on  the  knee  of  the  accoucheur,  and  in 
this  position  the  throat  is  cleared. 

In  the  more  severe  cases — real  asphyxia  livida — the  child  usually  has  gotten 
foreign  matter  deeply  into  the  lungs,  and  this  must  be  gotten  out — best,  in  my 
experience,  by  means  of  the  tracheal  catheter  (Fig.  730).  With  a  little  practice  the 
use  of  this  instrument  becomes  easy. 

When  the  air-passages  are  free,  it  is  time  for  external  stimulation.     As  a  rule, 


Introducing  the  Tracheal 
Catheter. 
The  index-finger  of  the  left  hand  pulls 
the  epiglottis  forward  and  comes  to  touch 
the  arytenoid  cartilages.  At  the  same  time 
the  catheter  is  passed  along  this  finger  until 
it  lies  over  the  rima,  just  behind  the  epiglot- 
tis. Now  the  inside  index-finger  pulls  the 
ver>'  tip  of  the  catheter  sharply  forward, 
while  the  right  hand  giving  the  tube  a  shght 
twisting  motion,  pushes  it  down  into  the 
trachea.  The  lips  are  applied  to  the  glass 
mouth-piece,  and  a  light  suck  draws  the 
contents  of  the  trachea  into  the  catheter, 
which  is  then  removed  and  its  contents  for- 
cibly blown  out  on  a  towel  for  inspection. 
Sometimes  the  sucking  on  the  catheter  is 
continued  as  it  is  withdrawn  to  clear  the 
whole  tract.  It  may  be  necessary  to  re- 
peat this  procedure  several  times.  It  is  wise 
also  to  compress  the  chest  between  the 
thumb  and  four  fingers  to  force  the  mater- 
ial out  of  the  smaller  bronchi,  to  gain  the 
advantages  claimed  for  Schultze's  swing- 
ings. By  pushing  the  catheter  deeply  into 
the  chest  and  turning  the  head  and  neck  of  the  child  sharply  to  either  side, 
the  right  and  then  the  left  bronchus  may  be  emptied. 


806 


THE    PATHOLOGY    OF    LABOR 


the  catheterization  of  the  trachea  has  stimulated  the  respiratory  center,  and  respir- 
ator}' movements,  in  the  form  of  gasps,  usually  folloAV  this  operation.  If  the  re- 
action is  too  slow,  the  buttocks  may  be  spanked,  the  back  rubbed  vigoroush^,  or 
gentle  traction  made  on  the  tongue  (Laborde,  1892).  CJrasping  the  tongue  be- 
tween the  thumb  and  index-finger,  it  is  gently  drawn  out  and  let  go  back  30  to  40 
times  a  minute. 

Among  the  host  of  external  irritants  employed  fur  tliis  purpose  may  be  mentioned  the  hot 
bath,  with  or  without  mustard,  wine,  etc.,  the  hot  and  cold  plunge,  cold  bath,  tickling  the  nares, 


Fig.  73L — Prochowxick's  Method  of  Resuscitation. 
The  child  is  suspended  by  the  feet,  the  forehead  resting  hghtly  on  the  table  so  as  to  deflex  the  ehin  and  straighten 
out  the  trachea.  The  body  is  gentl.v  shaken,  and  the  chest  compressed  between  the  thvinib  and  four  fingers  so  as  to 
squeeze  out  foreign  matter  from  the  bronchi.  Now  an  assistant  wipes  out  the  throat,  and  tlie  pressure  on  the  chest  is 
suddenly  relaxed.  Air  may  be  heard  rushing  in.  The  compression  and  sudden  release  may  be  repealed  10  to  20  times 
a  minute. 


snuff,  dilatation  of  the  sphincter  ani,  hj'podermic  injections,  electricity,  etc.  The  author  does  not 
use  the  hot  bath,  since  it  is  too  dcpres.sing.  Even  the  warm  bath  may  not  be  prolonged  over  five 
minutes.  A  better  method  is  to  wrap  the  infant  in  warm  towels  and  lay  it  on  a  warm-water  bag. 
The  alternating  cold  and  hot  plunges  are  distinctly  .shocking  to  the  tender  infant,  and  in  my 
opinion  dangerous,  as  well  as  unnecessary. 

Where  the  respiratory  center  is  still  responsive,  no  more  need  usually  be  done 
— indeed,  more  may  be  harmful.  The  accoucheur  simply  keeps  the  infant  covered. 
If  the  child  is  improving,  the  gasps  recur  with  increasing  frequency,  or  tiny  respir- 
atory motions  of  the  chest  become  visible  and  the  heart  impulse  grows  stronger 
and  regular.  Soon  the  gasps  become  double,  and  end  with  a  long  inspiration, 
expiration  being  attended  by  a  light  moan.     Now,  between  the  gasps,  the  tiny

respiratory  movements  of  the  chest  become  more  pronounced,  while  at  the  same 
time  the  cj'anosis  begins  to  lighten  and  give  way  to  redness,  soon  after  which  the 
child  gives  a  lusty  cry.  It  is  best  to  leave  the  infant  alone  as  long  as  it  improves, 
and  in  all  cases  precipitate  and  frantic  haste  with  trials  of  different  methods  in 
rapid  succession  is  to  be  condemned. 

If  improvement  is  not  immediate,  and  if,  from  the  start,  the  case  impresses 
one  as  one  of  asphyxia  pallida,  this  simple  treatment  does  not  suffice.  Time  maj' 
not  be  wasted  trying  the  various  skin  reflexes,  but  two  serious  purposes  must  be 
accomplished — first,  oxygen  is  to  be  gotten  into  the  fetus'  blood  by  artificial  res- 
piration; second,  the  circulation,  which  is  almost  in  a])eyance,  must  be  started 
again.  Of  the  numerous  methods  of  artificial  respiration,  only  three  are  really 
valuable — rhythmic  compression  of  the  child  in  inverted  suspension  (Fig.  731); 


Fig.  732. — MorTH-TO-Lrxc.  Ix.srFFL.vTiox  with  the  Trache.^l  Catheter  fSmellie). 
After  inserting  the  catheter  a.s  was  done  for  the  removal  of  mucus,  the  operator  fills  his  lungs  and  mouth  with  fresh 
air,  then  applies  his  lips  to  the  mouth-piece,  with  his  (/toltis  closed,  and  simply,  under  the  gentle  action  of  the  cheeks 
(like  a  gla.ss-hlower),  forces  pure  warm  air  into  the  child's  lungs.  Only  as  much  as  can  be  held  in  the  mouth  may  be 
forced  in.  Compression  of  the  chest  causes  the  air  to  escape,  and  this  procedure  may  be  repeated  fifteen  times  a  minute. 
Chaussier,  in  .June,  IsOti,  recommended  oxygen  for  this  purpose.  I  have  u.sed  it  instead  of  air,  and  in  a  few  desperate 
cases  it  has  seemed  to  me  to  be  better,  but  there  is  danger  of  giving  too  much  and  causing  acapnia. 


mouth-to-lung  insufflation  with  the  tracheal  catheter  (Fig.  732),  and  Schultze's 
swingings  (Fig.  733). 

Which  of  these  three  methods  will  be  chosen  depends  on  the  severity  of  the 
asphyxia  and  the  preference  of  the  operator.  Autliorities  are  divided  as  to  the 
relative  value  of  tracheal  insufflation  and  Schultze's  swingings.  The  former  is  said 
to  be  dangerous  because  of  the  possible  production  of  emphj'sema  from  rupture  of 
the  alveoli,  and  it  requires  considerable  skill  in  intubation,  while  it  does  not  produce 
the  stimulating  effect  on  the  heart  and  blood-vessels  which  the  swingings  do. 
Bichat  proved  that  it  is  possible  to  blow  air  into  the  vessels  of  the  heart  and 
general  circulation  if  too  much  force  is  u.sed.  Performed  as  here  described,  I  be- 
lieve there  are  none  of  these  clangers,  and  insufflation  has  most  of  the  advantages 
of  the  swingings. 

Schultze's  swingings  are  really  dangerous,  though  most  of  the  accitlents  re- 
ported are  due  to  errors  of  teclmic  or  to  the  injuries  suffered  in  operative  delivery. 


808 


THE    PATHOLOGY    OF    LABOR 


Rupture  of  the  liver  or  of  the  spleen,  hemorrhages  into  the  peritoneum,  the  pleura, 
the  suprarenals,  and  spinal  cord;  shock;  deep  aspiration  of  matters  from  the  upper 

air-passages,  even  fractures 
of  the  clavicles  and  ribs,  have 
been  charged  against  this 
method,  perhaps  unjusth'. 
Schultze's  method  is  contra- 
indicated  in  premature  chil- 
dren, and  with  fracture  of  any 
of  the  bones,  and  where  the 
accoucheur  suspects  a  cerebral 
hemorrhage. 

To  start  the  circulation 
again  all  the  above  methods 
of  artificial  respiration  help. 
Schultze's  swingings  are  a 
strong  cardiac  stimulant,  the 
warm  bath,  with  rubbings,  an- 
other. In  a  few  cases  I  have 
successfully  stimulated  the 
heart  by  rapid  vibratory  per- 
cussion, and  to  hasten  the  cir- 
culation through  it  have  com- 
pressed the  heart  against  the 
chest-wall  from  below,  through 
the  relaxed  abdominal  wall. 
If  the  child  is  anemic  from 
blood-loss,  salt  solution  may 
be  supplied. 

My  routine  practice  in 
cases  of  asphyxia  pallida  is  as 
follows:  As  soon  as  the  child 
is  delivered  it  is  laid  on  a  sterile 
platter,  which  lies  on  the  lap; 
the  air-passages  are  cleared 
by  the  catheter;  the  cord  is 
tied  and  cut;  Prochownick's 
method  (Fig.  731)  is  used  for 
thirty  seconds,  during  which 
time  the  cardiac  pulsations 
and  any  respiratory  action  are 
determined;  the  tracheal  cath- 
eter is  inserted,  and  the  lungs 
are  filled  with  air  sj'stemati- 
cally  for  two  or  three  minutes, 
the  -child  being  well  wrapped 
up;  if  there  is  no  improvement, 
which  is  the  rare  exception, 
one,  two,  or  three  Schultze's 
swingings  are  given,  and  the 
child  is  laid  in  a  warm  })ath  to 
observe  the  effects;  if  none, 
the  tracheal  catheter  is  again 
inserted,  the  operator  arranges 


Fig.  733. — Schultze's  Swingings.  Above,  Expiration;  Below,  Ln- 
spiration. 
Schultze's  swingings,  recommended  in  1866,  are  the  most  powerful 
and  dangerous  of  all  methods,  and  are  reserved  by  the  author  for  most 
desperate  cases.  The  child  is  grasped  with  the  thumbs  over  the  front 
of  the  chest,  the  index-fingers  in  each  axilla  to  prevent  it  from  flying 
out  of  the  operator's  grasp,  the  three  fingers  of  each  hand  distributed 
over  the  back.  The  head  is  held  steady  by  pressure  with  the  wrists. 
The  accoucheur  stands,  planting  the  feet  firmly  wide  apart.  The 
child  is  slowly  swung  up  over  the  head,  so  that  its  feet  fall  downward, 
and  thus  held  for  a  few  seconds.  This  is  expiration,  and  often  foreign 
bodies  are  emptied  from  the  air-passages.  An  assistant  removes  these 
with  the  little  finger  wrapped  in  gauze.  Now  the  child  is  swung  out, 
forward,  and  then  down  between  the  legs,  letting  the  motion  begin  and 
end  very  evenly  and  gently.  A.n  audible  inspiration  must  accompany 
this  movement.  The  cliild  is  then  put  in  a  warm  bath  or  wraj^ped  in  a 
warm  towel,  the  effects  being  watched.  The  heart  is  felt  to  beat  power- 
fully, and  a  gasp  usually  rewards  the  effort.  If  no  improvement  is  ob- 
served, the  process  may  be  repeated.  It  is  rare  that  more  than  10  swing- 
ings are  required,  but  Knapp  gave  one  infant  over  600,  and  while  it 
lived,  he  is  inclined  to  a.scribe  the  recovery  to  other  causes.  It  is  import- 
ant not  to  compress  the  chest  laterally,  to  hold  the  head  securely  by 
the  wrists,  not  to  throw  the  child  forward  with  a  jerk,  and  to  have  the 
flexion  of  the  .spinal  colunm  take  place  only  in  the  dorsolumbar  and  not 
in  the  thoracic  region.  Only  if  thus  performed  are  the  swingings  suc- 
cessful and  safe.

things  conveniently  and  keeps  up  the  artificial  breathing  until  the  child  recovers  or 
until  its  condition  shows  that  further  effort  is  useless.  Several  instruments  have 
been  devised  for  supplying  oxygen  through  the  catheter  automatically,  and  for 
artificial  respiration  (Engelman). 

How  long  to  keep  up  efforts  at  revi\-al  depends  on  the  case.  U.sually  an  hour 
suffices  to  show  if  there  is  any  hope  at  all  of  saving  the  infant,  and  the  remedial 
measures  should  be  kept  up  for  two  or  even  three  hours  if  the  heart  beats.  Cases 
are  on  record  of  recovery  after  two,  three,  and  even  four  hours'  effort.  With 
a  cerebral  hemorrhage  or  a  fracture  at  the  base,  the  heart  may  beat  as  long  as  the 
blood  is  kept  supplied  with  oxygen.  In  one  such  case  I  kept  up  mouth-to-lung  in- 
sufflation for  nine  hours  steadily,  the  heart  beating  strongly  and  the  child's  color 
being  good  until  I  stopped,  when  the  circulation  gradually  ceased,  there  not  having 
been  a  single  gasj)  to  reward  the  prolonged  effort. 

After-treatment. — Asphyxiated  and  premature  children  and  children  delivered 
by  severe  operative  procedures  should  always  be  watched  for  the  first  hours  and 
days  after  labor.  Not  seldom  they  develop,  in  a  few  minutes  to  a  few  hours,  a 
secondary  asphyxia.  This  is  due,  usually,  to  atelectasis  pulmonum,  but  the  author 
has  reason  to  believe  that  there  is  some  pulmonary  circulatory  trouble  in  addition. 
In  other  cases  a  small  hemorrhage  occurs  in  the  medulla.  The  child  may  be 
found  dead  in  its  crib,  or  it  may  turn  pale,  cyanotic,  with  a  reddish  line  at  the  skin 
margin  on  the  lips;  it  whines  or  grunts  at  each  expiration;  soon  it  becomes  uncon- 
scious, will  not  cry  on  being  hurt,  and  dies  under  a  slow  asphyxia.  These  chil- 
dren are  also  more  subject  to  icterus,  to  sepsis,  especially  the  bronchial  and  in- 
testinal forms,  and  if  they  grow  up,  are  not  likel}'  to  be  so  strong  as  other 
children — chronic  atelectasis.  Unless  they  can  have  mother's  milk,  thej'  often 
die  simply  from  exhaustion.  The  treatment  of  secondary  asphj-xia  with  atelec- 
tasis is  not  at  all  satisfying.  I  have  tried  all  lalo^^^l  methods  of  distending  the  lungs 
and  have  failed.  The  lung  is  solid  wath  exudate.  Often  cerebral  hemorrhage  is  the 
cause  of  the  secondary  asphyxia,  the  pathologic  basis  of  which  is  pulmonarj'  edema. 
The  incubator  connected  wdth  outside  air  helps  a  great  deal  in  the  treatment. 
Attacks  of  syncope  are  treated  with  the  warm  bath,  oxygen  insufflation,  and  artifi- 
cial respiration. 

INJURIES  TO  THE  CHILD  IN  BIRTH 

Manifestly,  it  is  impossible  to  consider  all  the  injuries  which  the  infant  may 
suffer  during  birth.  Only  a  few  of  the  most  common  and  most  important  will  be 
described,  and  as  mam-  of  the  others  as  possible  named.  A  glance  at  the  list  will 
show  the  reader  what  a  gantlet  of  perils  the  infant  runs  on  its  way  into  the  world. 
Since  a  great  many  of  them  are  preventable,  the  list  will  also  show  what  a  heavy 
responsibility  rests  on  the  shoulders  of  the  modern  accoucheur. 

The  Head. — Caput  succedaneum,  the  soft,  boggy  tumor  which  forms  on  the 
presenting  part  in  prolonged  labor,  was  discussed  on  p.  144.  It  must  be  dis- 
tinguished from  cephalhematoma,  which  is  a  hemorrhage  under  the  periosteum  of 
the  skull  (Fig.  734).  Cephalhematomata  are  always  due  to  injury,  which  may  be 
made  by  the  accoucheur  in  forceps  or  breech  extraction,  or  by  the  natural  forces, 
especially  in  cases  of  spacial  disproportion.  I  have  seen  two  cases  after  spon- 
taneous breech  deliveries.  Fissure  of  the  bones,  that  is,  linear  fractures,  often 
accompany  the  blood  extravasation.  They  may  be  single  or  multiple,  are  always 
limited  by  the  sutures  (unless  the  latter  are  ossified),  and  are  absorted  in  from  two 
weeks  to  three  months,  depending  on  their  size.  At  the  edge,  where  the  periosteum 
isliftedup,  a  ridge  of  bone  develops,  and  this  requires  still  longer  time  to  dis- 
appear. The  diagnosis  is  easy;  there  is  a  soft,  non-pulsating,  fluctuating,  elastic 
tumor  over  one  of  the  flat  cranial  bones.  In  the  differential  diagnosis  caput 
succedaneum,  hernia  cerebri,  and  neoplasm  are  to  be  considered.

ACCIDENTS   TO   THE    CHILD  811 

Direct  injuries  to  the  scalp;  cutting  by  forceps;  pressure  necrosis  from  con- 
tracted pelves  and  exostoses;  punctures  and  tears  with  instruments  under  the  mis- 
taken idea  that  the  scalp  was  the  membranes;  tearing  off  of  an  ear;  crushing  of  the 
nose  (later  deflected  septum  and  ethmoid  troubles) ;  subcutaneous  hematomata  in 
the  cheeks  and  neck  from  forceps;  fracture  and  dislocation  of  the  jaw  (breech  extrac- 
tions) ;  tearing  oft'  of  an  eyelid;  comi)lete  enucleation  of  the  eyeball;  conjunctival  hem- 
orrhages— all  these  I  have  seen  either  in  my  own  or  in  consultation  practice.  W'olft 
and  Paul  have  found  retinal  hemorrhages  and  detachment  in  a  large  percentage  of 
normal  labors,  and  almost  always  after  operative  delivery  with  more  or  less  as- 
phyxia. Fracture  of  the  orbital  i)lates;  hemorrhages  into  the  chambers  of  the  eye 
and  around  the  eye  (exophthalmos),  in  the  optic  nerve;  dislocation  of  the  lens; 
paralysis  of  the  eye  muscles  (from  intracranial  as  well  as  extracranial  trauma); 
congestion  of  the  optic  nerve  vessels  and  secondary  atrophj^  of  the  bulb — have  all 
been  reported,  and  should  lead  to  care  in  operations  (Wolff,  Lequeux).  Similar 
hemorrhages  occur  in  the  ears  and  may  cause  deafness.  It  would  be  interesting 
to  learn  how  many  deaf-mutes  had  difficult  births. 

Other  Injuries. — Fractures  of  the  skull  have  already  been  considered.  The 
spoon-shaped  and  grooved  depressions  of  the  bone  w^hich  need  not  always  be  com- 
plicated with  fracture  or  fissure  are  the  commonest,  but  fracture  at  the  base, 
disruption  of  the  occipital  plate  from  the  condyles  (with  breech  extraction);  tear- 
ing of  the  tentorium  cerebelli,  which  is  not  infrequent  (Beneke),  laceration  of  the 
capsular  ligament  between  axis  and  atlas,  and  rupture  of  the  sutures  have  been 
observed. 

Hemorrhage  into  or  on  the  brain  may  accompany  a  fracture,  a  fissure,  or  come 
from  rupture  of  a  cerebral  or  meningeal  vessel;  it  may  be  the  result  of  asphyxia — 
indeed,  from  no  apparent  cause,  as  in  one  of  my  cases  after  a  spontaneous  labor 
attended  with  no  compression  of  the  head  and  no  anaerosis.  Syphilitic  children  are 
predisposed  to  brain  hemorrhages  (Osier).  Bleeding  may  take  place  in  the  spinal 
canal   also,  and  be  limited  here. 

The  symptoms  come  on  within  three  or  four  days, — usually  the  second  day, — 
and  if  the  bleeding  is  a  slow  one,  maj'  last  a  week  or  more.  They  are  restlessness, 
crying,  refusal  of  food,  twitchings  of  groups  of  muscles,  of  one  whole  side,  or 
general  tremors,  especially  of  the  lower  jaw,  signs  of  local  irritation,  for  example, 
chewing  or  sucking  movements,  irregular  pupils,  nystagmus,  Bal)inski  sign,  sharp, 
high-pitched,  cramp-like  cry,  coma,  cyanosis  of  the  lips,  often  fever,  even  103°  F., 
pallor  of  tiie  skin  with  dermographism,  rapid  and  irregular  respiration,  sometimes 
Cheyne-Stokes',  rapid  pulse,  160  to  180,  prominent  tense  fontanels,  convulsions, 
rigidity  of  the  body,  then  paralysis  with  cyanosis,  cessation  of  respiration,  and 
finally  of  the  heart. 

The  prognosis  of  cerebral  hemorrhage  is  not  absolutely  bad.  A  few  of  the 
children  presenting  even  positive  signs  may  recover,  but  usually  the  later  history 
is  unfavoraljle — epilepsy,  idiocy,  spastic  paralyses,  etc. 

Mild  symptoms  of  "meningisme"  are  not  seldom  observed  after  o])erative 
deliveries.  They  are  probal)ly  due  to  acute  cerebral  congestion,  possibly  with  tiny 
hemorrhages,  and  subside  in  a  few  days.  The  treatment  of  cerebral  hemorrhage 
in  infants  is  symptomatic.  It  consists  of  the  administration  of  sodium  bromid 
and  chloral,  of  each  2  grains  per  rectum  every  six  hours;  mother's  milk,  and  quiet; 
ice-cap.  Lumbar  jiuncture  may  be  used  for  diagnosis;  as  a  therapeutic  measure 
it  offers  little  hope.  If  the  symptoms  point  to  cortical  pressure,  that  is,  if  they  are 
localized,  trephining  should  l:>e  considered.  ]\Iore  is  to  be  hoped  from  a  decom- 
pression operation  than  we  have  heretofore  expected  (Commandeur,  Gushing). 

Facial  pai-alysis  frequently  results  from  injury  to  the  nerve  as  it  leaves  the 
stylomastoid  foramen.  Forceps  are  usually  to  blame,  but  compression  from  a  con- 
tracted pelvis  or  alniormal  attitude  of  the  child,  for  example,  sharp  flexion  of  the 


812 


THE    PATHOLOGY    OF    LABOR 


neck  on  the  shoulder,  may  cause  it  (]\lace).  Central  lesions  of  the  nerve  are  due 
to  cerebral  trauma  and  hemorrhage.  Here  the  parah'sis  comes  on  after  the  first 
day,  and  in  the  perijjheral  forms  it  appears  right  after  delivery.  Usually  in  a  few 
hours  to  a  few  days  the  facial  deformity  is  gone,  but  it  may  last  three  months  or 
longer.  In  central  tyjjes,  and  if  there  is  a  fracture  of  the  temporal  bone,  it  may  be 
permanent.  The  paralysis  may  be  only  part  of  a  congenital  facial  hemiatrophy. 
The  differential  diagnosis  between  the  two  types  is  made  on  the  usual  lines;  periph- 
eral paralysis^  when  there  is  extensive  involvement  of  the  distribution  of  the 
nerve,  lagophthalmus,  absent  reflexes,  etc.,  and  central,  when  the  eye  is  not  in- 
volved, the  reflexes  present,  and  there  are  other  cerebral  sjTnptoms,  etc.  No  treat- 
ment is  required.  In  the  chronic  cases  muscular  atrophy  should  be  prevented  by 
massage  and  electricity. 

The  Trunk. — Fractures  of  the  spine,  disruption  of  the  vertebra^,  separation 
of  the  condyles  from  the  occipital  plate,  (hslocation  of  the  atlas  on  the  axis,  occur 
in  violent  breech  deliveries  and  cause  instant  or  rapid  death.  In  nearly  all  cases 
they  are  errors  of  art.  Palpation  of  the  spine  from  the  outside  or  through  the 
pharynx  ^^^ll  enable  the  diagnosis  to  be  made.  Complete  avulsion  of  the  trunk 
from  the  head  is  rare;  the  head  may  be  torn  off  the  l)ody,  or  the  body  from  the 
head,  leaving  the  latter  in  the  uterus,  two  cases  of  which  have  come  to  my  knowl- 
edge. Unless  the  tissues  are  pathologically  soft,  macerated,  or  actually  brittle, 
such  an  occurrence  is  the  result  of  delirium  operatoriwn,  an  acute  lapse  of 
operative  reason  which  may  affect  the  accoucheur  after  much  loss  of  sleep,  the 
nervous  wear  of  a  prolonged  labor,  the  exactions  of  the  family,  combined  with  the 
sudden  appearance  of  extraordinary  difficulties.  The  head  in  these  cases  is  usually 
easily  removed,  but  it  has  been  left,  to  come  away  finally  by  prolonged  suppur- 
ation, with  fistulas,  lasting  months  or  years,  or  the  woman  may  die  of  sepsis. 

Rupture  of  the  sternocleidomastoid  muscle  is  not  so  rare  an  accident  as  statistics 
would  show  it  to  be.  It  is  often  overlooked  or  intentionally  secreted  for  fear  of  the 
legal  responsibility,  which  older  authors  erroneously  attached  to  it.  Rupture  of 
a  healthy  sternomastoid  can  be  brought  about  only  bj^  very  violent  traction,  com- 
bined with  extreme  torsion  of  the  head.  I  have  often  demonstrated  the  possibility 
of  turning  the  head  of  a  new-born  infant  through  an  arc  of  200  degrees  or  more 
without  even  making  it  cry.  The  blade  of  the  forceps  may  directly  crush  the  muscle, 
and  this  uijury,  in  the  absence  of  antecedent  disease,  in  my  opinion  is  more  likely 
to  cause  permanent  caput  obstipum,  than  that  of  overstretching  in  breech  de- 
liveries, though  most  of  the  reported  injuries  (not  developed  wry-neck)  occurred 
■s\dth  breech  presentation.  Injury  to  other  cervical  muscles  may  increase  the  scar 
formation  and  consequent  distortion. 

Two  conditions  are  found — a  hematoma  in  the  muscle,  usually  in  the  upper 
third,  and  a  fusiform  enlargement,  attended  with  great  tenderness  and  often  febrile 
reaction.  Without  doubt — and  in  this  the  author  is  sustained  by  Pincus  and  Peter- 
sen— the  muscle  was  already  shortened  and  pathologically'  altered  while  the  child 
was  still  in  utero,  and  the  labor  was  only  the  acting  cause.  Caput  obstipum  may 
follow  normal  and  easy  labors,  with  and  without  injury  to  the  muscle  determin- 
al>le  at  birth,  all  of  which  is  important  from  a  medicolegal  point  of  view.  Indeed, 
the  frequent  concomitant  facial  hemiatrophy  points  to  a  central  origin  of  the 
disease.  Shortening  or  rigidity  of  the  muscles  will  be  found  not  infrequently  in 
new-born  children  which  have  lain  in  the  uterus  in  a  cramped  attitude  for  longer 
periods,  and  especially  if  the  liquor  amnii  is  scanty.  Indeed,  even  the  head  of  the 
child  may  be  flattened  or  twisted.  For  example,  in  breech  cases,  in  primipara^,  the 
posterior  sternomastoid  is  shortened  and  the  anterior  parietal  bone  flattened; 
in  multiparse,  owing  to  the  pendulous  belly,  the  posterior  parietal  is  flattened  and 
the  anterior  sternomastoid  shortened.     Sometimes  the  arms  or  the  legs  of  the  child 


ACCIDENTS   TO   THE    CHILD  813 

are  fixed  by  the  shortened  muscles  in  bizarre  attitudes,  and  it  requires  some  force 
to  straighten  them.     The  bones  may  be  bent  and  broken  by  the  forces  of  labor. 

If  the  healthy  muscle  is  crushed  or  torn,  whether  or  not  a  hematoma  forms, 
spontaneous  recovery  is  the  rule,  and  shortening  is  absent,  a  fact  which  experience 
in  general  surgery  will  confirm.  If  the  injured  muscle  becomes  infected,  by  way 
of  the  Ijlood,  from  the  bowel,  the  navel,  or  the  lungs  (Mikulicz),  a  myositis  may 
occur  and  shortening  will  follow.  Hematomata  are  usually  observed  shortly  after 
birth  as  a  hard  knot  in  the  muscle,  which  is  onl}'  slightly  tender.  Myositis  is  found 
later — fourth  to  twenty-first  day — as  a  hard,  fusiform  swelling  of  the  whole  muscle, 
exceedingly  tender,  together  with  febrile  symptoms.  Myositis  causes  the  child  to 
cry  much,  especially  when  handled;  indeed,  these  sjTnptoms  may  attract  atten- 
tion to  the  trouble.  The  early  diagnosis  is  easy, — one  finds  the  head  turned  to  the 
affected  side,  the  tenderness,  and  the  tumor.  In  paral3'sis  of  the  nervus  acces- 
sorius  the  head  is  turned  to  the  well  side.  This  latter  is  similar  in  cause  to  facial 
paralysis,  and  usually  heals  quickly.  In  later  life  dislocation  of  the  vertebrae  and 
facial  hemiatrophy'  come  up  for  consideration. 

Treatment  of  injury  to  the  sternomastoid  and  of  the  other  cer\'ical  muscles 
consists  of  prevention,  in  the  first  place,  and  rest  of  the  muscle  after  it  occurs. 
During  breech  deliveries  the  possibility'  of  injur}'  must  be  borne  in  mind,  but  dur- 
ing forceps  operations  it  is  usually  impossible  directly  to  protect  the  muscles,  except 
by  a  strict  observance  of  the  indications  and  proper  technic.  After  delivery  the 
child  is  to  be  handled  as  little  and  as  carefully  .as  possible,  the  nurse  being  prop- 
erly instructed.  In  several  cases  I  had  the  infant  strapped  to  a  well-padded  board 
like  a  papoose  for  a  week,  and  bathing  omitted  (Couvelaire,  Behm). 

Injuries  to  every  one  of  the  viscera  of  the  chest  and  abdomen  have  been  re- 
ported, rupture  with  hemorrhage  being  the  usual  finding.  Fractures  of  the  ribs  and 
sternum  in  version  and  breech  extraction  have  occurred.  In  one  case  I  found  that 
the  attending  accoucheur  had  dilated  and  ruptured  the  anus,  thinking  it  was  the 
tightly  closed  cervix,  and  in  another  the  child's  perineum  and  rectovaginal  septum 
had  been  torn  through  under  the  same  erroneous  impression.  The  swollen  scrotum 
has  been  held  for  the  membranes  and  punctured.  Spontaneous  rupture  of  the  um- 
bilical cord  occurred  in  two  cases  in  the  service  of  the  Chicago  L}dng-in  Hospital 
Dispensary,  in  one  of  which  the  child  died.  The  cord  in  one  case  was  very  brittle. 
During  a  forceps  operation  I  inadvertently  cut  the  cord  clean  across  with  the  very 
tip  of  the  blade.  Tearing  of  the  cord  off  the  placenta,  off  the  belly,  once  with  strip- 
ping up  of  the  abdominal  wall,  rupture  of  the  veins,  rupture  of  a  large  varicosity, 
have  all  been  observed,  either  with  or  without  the  action  of  external  trauma 
(important  medicolegally).  A  too  brittle  cord,  coiling,  or  a  knot  is  usually  respon- 
sible for  the  spontaneous  injuries. 

Paralysis  of  the  muscles  of  the  extremities  is  not  an  infrequent  result  of 
severe  operative  deliveries.  Central  cerebral  or  spinal-cord  lesions  result  usually  in 
extensive  paralysis,  often  with  rigidity  and  athetosis,  for  example,  cerebral  spastic 
paralysis  (Little),  diplegia,  hemiplegia,  paraplegia.  Of  the  local  paralysis,  Duchenne- 
Erb's  is  clinically  the  most  important,  though  isolated  paralyses  and  pareses 
occur — for  example,  one  whole  arr^i,  the  forearm  and  elbow,  from  brachial  nerve 
injury  or  callus.  Erb's  parah'sis  is  due  to  injury  of  the  fifth  and  sixth  motor  roots 
of  the  brachial  plexus,  such  injury  being  due  to  direct  pressure  on  these  nerves  as 
they  issue  from  between  the  scaleni  muscles,  or  to  compression  between  the  clavicle 
and  the  first  rib,  to  tearing  of  the  nerves  by  direct  trauma,  as  from  a  broken  clavicle, 
or  overstretching  from  excessive  pulling  on  the  neck,  or  from  tearing  of  the  roots  of 
the  nerves  out  of  the  spinal  cord.  The  paralysis  is  usually  a  traction  lesion  and  may 
be  unilateral  or  bilateral.  Compression  by  the  blade  of  the  forceps  and  by  callus- 
formation  is  also  to  be  mentioned,  and  in  these  cases  the  paralysis  is  a  little  more 
likely  to  disappear.     The  muscles  involved  are  the  deltoid,  the  supraspinatus  and 


814 


THE    PATHOLOGY    OF    LABOR 


infraspinatus,  the  coracobracliialis,  hrat'liialis  internus,  the  l^icops,  and  in  some 
cases  the  supinatores  longus  and  brevis.  A  characteristic  position  is  assumed  by 
the  arm.  It  hangs  flaccid  at  the  side  of  the  chest,  with  the  hand  rotated  inward, 
the  thumb  pointing  back.  Flexion  of  the  forearm  on  the  arm  and  supination  are 
impossi])le.  SensibiUty  remains  intact,  l^ut  muscular  atrophy  is  rapid.  The  prog- 
nosis is  bad.  A  few  cases  in  which  the  signs  are  mild,  and  perhaps  due  to  bruis- 
ing, with  exudate  around  the  nerve-roots,  may  recover,  but  if  the  paralysis  lasts 
over  a  week,  or  if  neuritis  exists  the  outlook  is  gloomy  (Taylor  and  Clark). 

The  greatest  field  lies  in  prevention.  In  ordinary  labor,  during  the  delivery  of 
the  shoulders,  care  nuist  be  taken  not  to  lift  the  head  up  nor  to  pull  it  down  from 
behind  the  pubis  too  sharply,  and  in  breech  cases  the  neck  may  not  be  stretched

This  is  the  so-called  Erb's  point.      Sketches  below  show  usual   mechanisms  of  injury.      In  one  the  nerve-roots  may  be

too  much,  nor  the  fingers  allowed  to  draw  directly  upon  the  cervical  muscles 
and  nerves.  When  the  clavicles  are  fractured,  Schultze's  swingings  may  not  be 
practised.  In  one  case  I  was  convinced  that  the  end  of  the  bone  ground  into  the 
cervical  plexus  during  this  operation.  An  x-ray  should  be  taken  to  determine  if 
a  broken  bone  is  the  cause,  or  a  subluxation  of  the  head  of  the  humerus.  In  the 
differential  diagnosis  central  lesions,  syphilis,  etc.,  are  to  be  considered.  Treatment 
is  on  general  neurologic  lines.  Lately,  nerve  transplantation  operations  are  being 
done  on  such  cases. 

Fracture  of  the  hones  of  the  extremities,  especially  of  the  clavicle,  is  quite  common. 
A  critical  examination  of  new-born  children,  as  Riether  has  done,  will  show  that  this 
occurs  much  oftener  than  is  expected.     It  may  be  the  hard  lump  on  the  bone

(the  callus)  wliich  first  draws  attention.  (  lavicle  fractures  occur  from  direct  trauma, 
as  by  pulling  on  the  bone  in  breech  presentation,  or  indirectly  l)y  ])ulling  on  the  arm 
or  the  head,  the  bone  being  caught  between  the  source  of  the  power  and  the  pelvis. 
Bringing  down  the  arms  in  either  head  or  breech  presentations,  pulling  up  or  down 
on  the  head  to  deliver  the  trunk,  pulling  with  the  finger  in  the  axilla,  and  even 
the  power  of  natural  labor  when  the  shoulder  stems  against  the  pelvis,  may  break 
the  l)one.  I  observed  one  fracture  of  the  clavicle  in  a  spontaneous  labor  with  very 
strong  expulsive  pains  and  heard  the  bone  crack.  If,  after  every  operative  delivery, 
the  child  be  carefully  inspected  for  injuries,  such  a  fracture  will  not  escape  notice, 
mobility,  crepitus,  and  deformity  being  present.  Greenstick  fracture  may  occur. 
The  favorite  site  is  the  outer  third,  but  the  middle  may  break  under  direct  pres- 
sure, and  the  bone  may  break  at,  or  be  torn  from,  its  attachment  to  the  sternum

in  the  axilla,  the  arm  bandaged  to  the  side,  and  the  bandage  well  sewed  in  place. 

Fracture  of  the  humerus  results  from  direct  trauma  in  delivering  the  arms.  I 
have  twice  deliberately  broken  this  Ijone  to  save  the  child  and  succeeded.  Separa- 
tion of  the  diaphj'^is  from  the  epiphysis  is  much  more  common  and  more  serious 
because  it  may  easih'  be  overlooked.  The  epiphysis  is  rolled  out,  the  arm  rolled  in 
(like  an  Erb's  paralysis),  and  if  healing  is  thus  allowed,  permanent  disability  and 
shortening  result.  To  prevent  such  injuries  the  proper  technic  should  be  practised 
in  an  arm  and  shoulder  delivery.  Dislocation  of  the  humerus  is  very  rare — usually 
a  fracture  is  mistaken  for  it. 

Fracture  of  the  femur  is  almost  always  an  error  of  art,  too  much  force,  or  force 
applied  in  a  wrong  direction,  being  the  cause.  Bringing  down  the  leg  with  bad  tech- 
nic. grasping  it  improperly,  and  pulling  out  of  the  axis  of  the  pelvis  are  usually  re- 
sponsible.    Nowadays  few  accoucheurs  put  the  forceps  on  the  breech  or  use  the  blunt 


816  THE    PATHOLOGY    OF   LABOR 

hook  or  slings.  Even  the  finger  in  the  groin  may  break  the  bone.  Dislocation  of  the 
femur  is  rarer  than  fracture,  but  separation  of  the  epiphysis  is  commoner.  It  may 
be  impossible  to  distinguish  ])etween  congenital  and  acquired  dislocation  of  the 
femur- — indeed,  a  traumatic  dislocation  can  hardly  occur,  fracture  of  the  epiphysis 
usually  being  the  result  of  force  exerted  on  the  joint. 

Spontaneous  fracture  of  any  of  the  long  bones  may  occur  in  labor.  In  one 
of  my  cases  two  children  of  one  mother  had  broken  clavicles  because  of  fragility 
of  the  bones.  Besides  fractures,  the  extremities  may  be  torn  or  bruised  or  infected 
by  the  attendant,  or  the}'  may  suffer  pressure  and  gangrene  by  being  imprisoned 
between  the  head  and  the  pelvis.  If  the  a;-ray  is  to  be  used  to  aid  the  diagnosis 
of  fractures,  etc.,  the  exposure  must  be  very  short,  since  young  infants  are  sus- 
ceptible (O'Dormell). 

A  ver}'  important  consideration  is  the  medicolegal  aspect  of  all  these  injuries, 
since  too  often  the  physician  has  to  defend  himself  against  damage  suits  because 
of  them.  While  it  is  true  that  most  of  these  traumatisms  can  be  prevented  by 
proper  application  of  our  art,  it  is  equally  true  that,  with  few  manifest  exceptions, 
they  can  be  brought  about  by  the  forces  of  natural  labor  alone.  Since  this  is  a  fact,  in 
any  given  medicolegal  case  it  will  be  necessary  to  prove  that  the  particular  injury  was 
plainly  due  to  carelessness,  ignorance,  or  lack  of  skill  on  the  part  of  the  accou- 
cheur. In  passing  judgment,  also,  these  things  must  be  borne  in  mind :  Our  medical 
schools  do  not  as  yet  furnish  enough  material  so  that  the  general  practitioner  can 
get  the  proper  training  to  meet  all  the  emergencies  that  may  arise;  the  surround- 
ings of  the  labor  case  in  a  home;  a  low  bed  and  none  or  inefficient  assistance;  the  loss 
of  sleep;  the  nervous  wear  and  tear  of  a  confinement  case,  and  the  state  of  mental 
fatigue  in  which  the  accoucheur  often  has  to  undertake  the  most  dangerous  and 
delicate  operations,  involving  two  lives;  and,  finally,  many  of  the  accidents  named, 
have  occurred  in  the  hands  of  the  best  obstetricians  the  world  has  known.

SECTION  VII 
PATHOLOGY  OF  THE  PUERPERIUM 


Nowadays  the  puerperium,  aside  from  after-pains  and  minor  disturbances 
of  urination  and  of  lactation,  is  usually  an  uneventful  convalescence.  When  the 
soreness  is  gone  from  the  muscles  and  joints  and  the  body  functions  are  ordered, 
which  requires  about  seventy-two  hours,  the  puerpera  should  feel  as  well  as,  if  not 
better  than,  she  ever  did.  Two  dangers,  however,  beset  her:  infection  of  the 
genitalia  and  infection  of  the  breasts.  Naturally,  a  Avoman  at  this  time  may  be 
seized  with  any  general  or  local  disease,  as  typhoid,  pneumonia,  the  exanthemata, 
erysipelas,  etc.,  and  such  affections  are  usually  aggravated  by  the  puerperal  state. 
In  importance,  however,  puerperal  infection  overshadows  everything  else. 


CHAPTER  LXIII 

PUERPERAL  INFECTION 

Puerperal  fever  is  a  term  introduced  by  Richard  IVIorton  in  1692  to  apply 
to  an  acute  febrile  disease  which  seized  lying-in  women  and  exhibited  a  high  degree 
of  fatality. 

History. — In  the  primitive  practices  of  savages  untouched  by  civiUzation  are  found  many 
evidences  that  puerperal  fever  existed  among  them,  and  that  means  of  prevention  were  adopted 
— for  example,  the  isolation  of  the  parturient  and  puerperal  members  of  the  tribe,  the  cleansing 
bath  in  a  stream  after  labor,  the  fumigations  of  the  vulva  with  aromatic  herbs,  fumigation  of  the 
apartment  after  the  puerpera  left  it,  washing  the  belly  with  banana  wine,  etc.  In  the  Ayur  Veda 
of  Susruta,  a  thousand  years  before  Christ,  it  is  mentioned.  Hippocrates  (400  B.  c.)  describes  cases 
of  it  so  accurately  that  the  words  could  well  be  read  in  a  modern  class-room.  He  mentions  epi- 
demics of  the  fever.  Celsus  and  Galen  describe  it,  and  historic  references  to  it  throughout  the 
middle  ages  are  numerous.  The  first  authentic  report  of  an  epidemic  of  the  disease  is  given  by 
Hervieux,  and  is  said  to  have  occurred  in  Leipzig  in  1652  to  1665.  The  first  lying-in  ward  was 
established  in  Paris  at  the  Hotel-Dieu,  and  here  the  great  obstetricians,  Mauriceau,  de  la  Motte, 
Portal,  and  Peu,  obtained  their  experience.  Mauriceau  states  that,  in  1660,  an  epidemic  of 
puerp(^ral  fever  broke  out  in  the  citj-  of  Paris  and  in  the  Hotel-Dieu,  and  here  two-thirds  of  the 
women  delivered  died  of  it !  Even  in  1831  the  mortality  still  was  9  per  cent,  in  the  Paris  Matcrnite. 
In  17.50  and  1761  epidemics  occurred  in  London;  in  1772,  in  Edinburgh;  in  Berlin  in  177S — -to 
mention  only  a  very  few  of  those  reported.  Since  the  maternities  were  opened  to  students  at  the 
same  time  the  states  placed  dead  bodies  at  the  disposal  of  the  universities  for  study  and  instruction, 
it  is  easy — for  us — to  see  why  the  scourge  increased.  In  Vienna,  where  the  postmortems  of  the 
great  Rokitansky  were  so  assiduously  visited  bj-  the  students,  the  disease  raged  fearfully.  In 
1842  the  mortality  of  the  women  varied,  with  the  months,  from  18  to  31  per  cent.  Every  day  there 
were  two  or  three  autopsies  on  such  cases,  and  the  students  went  directly  from  the  morgue  to  the 
lying-in  room.  In  England  the  disease  was  very  well  known,  and  it  was  there  considered  con- 
tagious, like  smallpox.     (For  History  see  Fasbender,  Mauriceau,  Semmelwcis,  Holmes.) 

Definition. — Puerperal  fever,  or  puerperal  infection,  is  a  general  term  embrac- 
ing all  the  conditions,  usually  of  a  febrile  nature,  but  sometimes  non-febrile,  origi- 
nating from  infection  of  the  genital  tract  at  any  point  of  its  extent. 

It  matters  not  whether  the  symptoms  be  mild,  lasting  but  a  few  hours  or  many 
days,  whether  there  be  a  vulvitis,  an  endometritis,  or  a  septicemia,  whether  one 
52  817 


818  PATHOLOGY    OF   THE    PUERPERIUM 

of  the  milder  forms  of  saprophytic  bacteria  or  the  most  virulent  streptococcus  be 
causative,  whether  the  patient  has  fever  or  rapid  pulse — if  the  complexus  of  symp- 
toms points  to  a  genital  infection,  the  woman  suffers  from  puerperal  fever.  This 
definition  shuts  out  the  so-called  miasmatic  fevers,  the  essential  infectious  fevers, 
for  example,  typhoid,  diphtheria  of  the  throat,  erysipelas  of  all  other  portions  of  the 
body  but  the  genitals,  etc.,  and  since  it  includes  many  and  widely  differing  clinical 
forms  of  disease,  makes  a  careful  classification  of  these  forms  necessary.  This  is 
not  easy.  The  exact  nature  of  puerperal  infection  has  been  discovered  through  the 
science  of  bacteriolog3^ 

Up  to  the  seventeenth  century  the  theory  of  Hippocrates  was  the  generally  accepted  one. 
He  ascribed  the  disease  to  suppression  of  the  lochia,  taking  the  effect  for  the  cause.  Celsus  and 
Galen,  Avicenna,  Mauriceau,  Sydenham,  and  Alichaelis  accepted  this  theory.  If,  as  the  pre- 
sumable result  of  fright,  of  taking  cokl,  etc.,  the  lochia  ceased,  they  were  absorbed  into  the  blood 
and  caused  puerperal  fever.  Mercurialis,  and  especially  Puzos,  of  Paris,  taught  the  milk  theory. 
During  pregnancy  the  milk  secretion  begins,  but  it  is  all  determined  to  the  uterus,  where  the  fetus 
uses  it  for  nourishment.  After  labor  it  is  excreted  by  the  breasts.  If  by  catching  a  cold,  etc., 
the  secretion  should  be  checked,  so-called  milk  metastases  occur  and  cause  fever — again  mixing 
cause  and  effect.  Then  the  milk  appears  in  the  lochia  (the  purulent  lochia  of  sepsis),  in  the  peri- 
toneal ca\'ity  (the  pus  of  puerperal  peritonitis),  in  the  pleural  cavities  (pus  from  pleuritis),  or  in 
the  joints  (pyemic  arthritis).  Chemists  even  claimed  to  have  made  butter  from  the  exudate  in  the 
peritoneal  cavity,  one  saying  he  had  found  sour  milk  and  butter  under  the  skin  of  a  woman  dead 
of  puerperal  fever. 

There  was  no  lack  of  other  notions.  Plater,  in  1602,  said  it  was  a  metritis;  Hunter,  in  1780, 
a  peritonitis;  Tonnele,  in  1830,  a  lymphangitis,  etc.  Mauriceau  called  it  malignant  fever,  others 
a  gastric  or  bilious  fever,  puerperal  erysipelas,  typhus,  omentitis,  putrid  fever,  etc. 

Cruveilhier  said  it  was  somewhat  like  typhoid,  while  the  "essentialistes,"  as  they  were  called 
in  France,  among  whom  are  the  names  of  Dubois,  Depaul,  Litzman,  and  Michaelis,  said  it  was  due 
to  a  miasm  and  was  a  specific  contagious  process,  propagable  through  the  air,  and  governed  by 
telluric,  cosmic,  and  atmospheric  influences,  etc.,  a  view  later  held  by  Fordyce  Barker  in  America. 

Ideas  of  the  infectious  nature  of  the  disease  had  long  been  held.  Levret  (Paris,  1770),  in 
speaking  of  Smellie's  leather-covered  forceps,  asks  if  contagion  could  not  be  carried  in  the  blood 
which  decomposes  in  the  meshes  of  the  leather.  In  England,  Charles  White,  in  1772,  said  that 
other  persons  could  be  infected  by  the  discharges  of  a  septic  puerpera;  in  1795  Gordon  referred 
to  the  contagiousness  of  the  disease,  and  Denman,  in  1768,  declared  it  was  carried  by  physicians 
and  midwives  from  one  puerpera  to  another.  One  quotation,  whose  origin  I  cannot  find,  states 
that  the  disease  may  be  carried  on  sponges  used  on  several  puerpera.  Dr.  Blackman,  in  Edin- 
burgh, in  1845,  said  that  puerperal  fever  was  conveyed  by  the  dirt  under  the  finger-nails.  Ab- 
stention from  obstetric  practice  was  enforced  on  physicians  who  had  a  succession  of  puerperal  fever 
cases,  and  even  the  use  of  chlorid  of  lime  for  the  hands  as  a  disinfectant  was  recommended. 

In  1842  our  own  Oliver  Wendell  Holmes  heard  a  report  of  the  case  of  a  physician  who, 
inoculated  at  a  postmortem,  died  of  septicemia,  but  before  this  had  attended  several  women  in 
labor  who  also  died  of  the  same  disease.  Struck  with  this  association  of  fatalities,  he  investigated 
the  subject,  and  in  1843  published  his  results  in  a  paper  entitled  "The  Contagiousness  of  Puerperal 
Fever."  He  proved,  by  an  array  of  clinical  reports,  that  it  was  carried  from  one  patient  to  another 
as  a  contagium,  and  that,  also,  it  was  caused  by  inoculation  of  the  puerpera,  and  that  the  sources 
of  infection  could  be  erysipelatous  processes  as  well  as  cadaveric  poisons.  He  suggested  these 
rules  of  prophylaxis: 

"1.  A  physician  holding  himself  in  readiness  to  attend  cases  of  midwifery 
should  never  take  any  active  part  in  the  postmortem  examination  of 
puerperal  fever  cases. 

"2.  A  physician  present  at  such  postmortems  should  use  thorough  ablu- 
tion, change  every  article  of  dress,  and  allow  twenty-four  hours  or 
more  to  elapse  before  attending  a  case  of  midwifery. 

"3.  Similar  precautions  should  be  taken  after  the  autopsy  or  surgical 
treatment  of  cases  of  erysipelas  if  the  doctor  is  obliged  to  unite  such 
duties  with  his  obstetrical  work,  which  is  in  the  highest  degree  inex- 
pedient." 

Holmes'  views  met  violent  and  bitter  opposition  from  tlie  two  foremost  obstetricians  of  the 
time,  Hodge  and  Meigs,  and  made  very  little  impress  on  the  profession.  In  1855  he  again  took 
up  the  subject,  but,  unfortunately,  for  the  last  time. 

In  1847  Semmelweis,  a  j'oung  assistant  in  the  clinic  in  Vienna,  which  was  later  occupied  by 
Carl  Braun,  announced  that  puerperal  fever  is  caused  by  the  absorption  into  the  blood,  from  the 
genitals,  of  decomposed  animal  matter  from  any  source;  that  the  hands,  or  any  articl(>  brought  into 
the  genitals,  may  be  the  carriers  of  same.  He  did  not  come  upon  this  by  accident,  but  it  was  the 
result  of  years  of  hard  work  and  study.  He  noticed  that  the  division  of  the  clinic  which  was  used 
for  the  instruction  of  midwives  had  a  2.7  per  cent,  mortality  from  puerperal  fever,  while  that  for 
doctors  had  11.4  per  cent.,  and  that  the  children  were  affected  with  sepsis  proportionately  also. 
The  discrepancy  between  the  two  clinics  was  public  knowledge — it  was  the  subject  of  municipal

students  were  not  tau<iht  showed  the  best  rcsuUs  (except  the  Paris  Maternite,  where  the  midwives 
made  autopsies);  that  overcrowdinfi  of  the  hospital  had  no  influence;  tliat  fright  and  nervous 
influences  had  no  efi'eet ;  that  the  disease  aff"ected  the  married  as  well  as  the  single;  that  the  new- 
born children  died  of  the  same  disease  as  their  mothers;  that  no  alteration  of  the  diet,  of  the  venti- 
lation, of  the  methods  of  treatment,  produced  a  change  for  the  better — and  all  the  time  the  differ- 
ence in  the  conditions  of  his  clinic  from  that  of  the  midwives  mystified  and  oppressed  him.  He 
said:  "Everything  was  in  question;  everj-thing  was  unexplained;  everything  was  doubtful — 
only  the  large  number  of  deaths  was  a  positive  fact."  Finally,  the  (l(>ath  of  his  friend,  Professor 
Kolletschka.  gave  him  the  inspiration.  A  student  had  pricked  Kolletschka's  finger  at  an  autopsy, 
and  the  professor  died  of  septicemia.  The  postmortem  of  Kolletschka  struck  8emmelweis  by  its 
similarity  with  those  he  had  made  on  puerperal  fever  cases.  The  explanation  of  jiuerperal  fever 
was  tlien  clear.  The  hands  carried  particles  of  cadaveric  decomposition  into  the  puerperal  wounds, 
and  these  caused  puerperal  fever. 

With  the  cause  he  sought  the  remedy.  He  instituted  washing  of  the  hands,  cleaning  of  the 
finger-nails  ( !),  and  the  use  of  chlorin  water;  later,  chlorid  of  lime  solution.  The  result  was  dazzling. 
The  mortality  sank  to  1.27  per  cent,  in  184S,  even  lower  than  it  was  in  the  midwives'  clinic. 
Later  an  incident — rather,  an  accident — showed  him  that  any  decomposing  animal  matter  can  be 
causative.  Thirteen  women  lying  in  adjacent  beds  were  examined  in  succession  by  the  assistant 
and  staff.  The  first  was  a  case  of  gangrenous  carcinoma  of  the  cervix  of  the  uterus;  the  rest  were 
normal  cases — 11  of  the  12  women  died  of  puerperal  fever.  Later  a  woman  with  caries  of  the 
left  knee  became  the  origin  of  a  run  of  19  fatal  cases  of  infection.  Experimentally,  he  proved 
that  the  introduction  of  pus  and  ichor  from  these  women  was  fatal  to  puerperal  animals. 

At  the  same  time  that  the  mothers'  mortality  improved  the  infections  of  the  new-born  were 
substantially  reduced. 

Semmelweis'  theory,  then,  reads  that  puerperal  fever  is  a  resorption  fever,  brought 
about  by  the  introduction  of  decomposed  animal  matter  into  the  genitals.  He  said  that  this  matter 
could  come  from  cadavers,  from  infected  wounds  of  all  kinds,  and  was  carried  into  the  genital 
wounds,  the  uterus,  the  cervix,  and  the  perineum  by  the  finger  of  the  accoucheur,  the  instruments, 
the  douche-nozle,  the  sponges,  infected  air,  the  bed-linen,  the  bed-pans — indeed,  everything  which 
could  transport  the  decomposed  animal  matter  from  its  source  to  the  parturient  canal.  He  said 
that  the  disease  was  only  one  form  of  pyemia,  that  it  also  occurred  in  surgical  cases,  and  he  recom- 
mended his  methods  of  prevention  to  the  surgeons!  If  the  word  "bacteria"  is  substituted  for 
the  words  "decomposed  animal  matter,"  the  definition  of  puerperal  infection  is  perfect  as  we  be- 
lieve it  todaj'.  Semmelweis'  theor}%  like  most  great  truths,  was  not  accepted;  he  struggled  wth 
his  opponents  for  fifteen  years,  when  signs  of  dementia  appeared.  He  died  without  the  recognition 
he  deserved,  in  an  insane  asj'lum,  and,  curiouslj-,  of  pyemia. 

With  Bretonneau,  Pasteur,  and  Koch,  the  germ  theory  of  disease  was  born,  and  when  Lister 
came  in  the  seventies,  the  true  worth  of  Semmelweis'  work  was  appreciated.  To  an  obstetrician, 
then,  is  due  the  credit  of  pointing  the  correct  way  to  modern  antisepsis  and  asepsis. 

While  Holmes  proved  that  the  propagation  of  puerperal  fever  took  place  by  contagion  or 
inoculation  in  a  general  way,  to  Semmelweis  the  credit  must  be  given  for  having,  with  unerring 
aim,  struck  the  e.xact  cause  of  the  disease,  for  having  shown  unequivocally  that  it  is  an  infection 
of  the  genital  wounds,  and  for  having  indicated  the  correct  manner  of  prevention.  Holmes 
dropped  the  subject  after  a  few  efforts;  Semmelweis  fought  for  his  theorj'  and  the  lives  of  myriads 
of  women  with  all  his  powers,  and  quit  the  struggle,  as  Sinclair  says,  only  to  descend  into  the 
tomb. 

Since  1870  the  history  of  puerperal  fever  has  been  that  of  listerism.  Whereas  at  first  the 
women  were  delivered  under  a  carbolic-acid  spraj',  and  the  air,  which  Lister  believed  was  the 
dangerous  element,  excluded, — one  Russian  author  even  wishing  the  women  delivered  in  an 
antiseptic  bath, — later  the  hands  and  instruments  were  recognized  as  the  materia  peccans,  and 
rigid  antisepsis,  both  objective  and  subjective,  practised.  In  the  eighties  and  earlj'  nineties  the 
women  were  given  carbolic  and  bichlorid  douches  before,  during,  and  after  labor.  This  was  found 
harmful,  and  now  a  more  aseptic  technic  is  practised,  identical  in  principles  with  that  suggested 
by  Semmelweis  in  1847. 

Etiology. — Puerperal  fever  is  nothing  more  nor  less  than  an  infectious  wound 
disease.  Cruveilhier,  in  1831,  said  that  the  puerpera  was  a  wounded  person,  and 
Mauriceau,  in  1668,  called  the  lochia  a  wound  secretion,  likening  it  to  that  of  an 
amputation. 

Since  puerperal  infection  is  a  surgical  wound  infection,  it  follows  that  the  germs 
which  attack  surgical  wounds  will  also  be  found  attacking  the  puerpera.  This 
is  true.  The  pathology  of  puerperal  infection  is  the  same  as  that  of  surgical  infec- 
tions, but,  because  of  the  anatomic  structure  of  the  parts,  the  pliysiologic  changes 
of  pregnancy,  of  labor,  and  the  puerpcrium,  with  the  peculiar  chemisms  of  these 
functions,  manj'  variations  exist  which  demand  special  consideration. 

The  following  bacteria  have  been  found  as  positive  and  probal)le  causes  of 
puerperal  infection.  In  collecting  these  the  author  has  made  use  of  the  exhaustive 
articles  of  Walthard,  Schottmiiller,  and  Wegelius: 


PUERPERAL    INFECTION

Streptococcus  pyogenes. 
Diplcstreptoroc'cus  puerpcrali?;. 
Streptococcus  putridus. 
Diplococcus  lanceolatus  pneumoniae. 
Stapliyloooccus  aureu.s  and  albus. 
Bacillus  coli  coinnuine. 
Gonococcus  of  Xeis.ser. 
Bacillus  pneumonia?  of  Friedlander. 
Bacillus  pyocyaneus. 


Bacillus  proteus. 
Bacillus  aerogencs  capsulatus. 
Bacillus  fusiformis  and  spirilla  (hos- 
pital Kangrene). 
Bacillus  tj'phosus. 
Bacillus  tetani. 
Bacillus  anthracis. 
Bacillus  diphtheria?. 
Bacillus  influenza?. 


A  host  of  bacteria  of  putrefaction  and  decomposition  exi.st,  a  few  of  which  may 
be  mentioned:  Micrococcus  fcctidus,  Bacillus  funduliformis,  Bacillus  racemosus, 
Bacillus  radiiformis,  Bacillus  pseudotetani,  Bacillus  nebulosus,  Bacillus  caducus, 
Staphylococcus  parvulus,  anaerobic  streptococci,  and  many  more  named  and 
unnamed.  It  is  impossible,  with  our  present  cultural  methods,  to  grow  many  of 
the  bacteria  which  appear  in  smear  preparations. 

It  is  rare  to  find  one  of  this  numljer  the  sole  cause  of  the  disease.  Usually  two 
or  more,  even  to  the  number  of  15,  have  been  found.  The  streptococcus  combines 
with  the  staphylococcus,  or  the  Bacterium  coli  or  pyocj'aneus,  the  latter  increasing 
the  virulence  of  the  former.  Symbiosis  seems  to  aggravate  virulence.  The  proteus 
and  the  Bacterium  coli,  or  the  proteus  with  the  staphylococcus  group,  may  cause 
l)ad  infections,  as  do  the  combinations  of  coli  and  Bacillus  aerogenes  capsulatus. 

Sources  of  the  Infection. — These  bacteria  are  to  be  found  in  decomposing 
animal  and  vegetaljle  matter,  cadavers,  in  diseased  animals  and  human  beings,  their 
excreta,  in  the  air,  and  in  dust.  The  most  important  ultimate  sources,  so  far  as 
our  subject  is  concerned,  is  the  diseased  human  being.  The  poisons  are  carried 
from  suppurations,  gangrene,  ulceration,  infections  which  are  excreted,  as  diph- 
theria, scarlet  fever,  pneumonia,  nasal  catarrhs,  etc.,  erysipelas,  necrotic  cancers, 
lochia  (even  of  normal  puerperie),  the  menstrual  blood,  and,  very  commonly,  from 
postmortems. 

Modes  of  Transmission  to  the  Genital  Tract. — Semmelweis  distinguished  two 
modes  ot"  incjculation — one,  from  without,  exogenous  infection;  and  one  from  within, 
endogenous  infection. 

Autoinfedion.— As  our  knowledge  of  the  subject  grew  and  our  preventive 
measures  became  more  and  more  successful,  there  appeared  those  who  declared 
that  all  cases  of  puerperal  infection  were  exogenous  in  origin  (for  example,  Jaggard), 
and  that,  therefore,  when  a  woman  took  sick  with  a  puerperal  process,  some  one 
was  to  blame  for  it.  The  results  of  this  teaching  are  still  wide-spread  and  still  cause 
a  great  deal  of  injustice,  because  it  is  not  true.  Ahlfeld,  since  1885,  and  a  few 
others — Winckel,  Koch,  Tarnier,  Doleris — had  always  maintained  that,  in  addition 
to  the  inoculation  from  without  (hetero-infection),  the  woman  occasionalh'  became 
infected  from  bacteria  which  she  carried  in  her  own  person — autoinfection.  Leo- 
pold, Doderlein,  Kronig,  Fochier,  Pcstalozza,  and  Williams  denied  the  possibilitj'. 
Some  of  these  authors  have  changed  their  minds.  Ahlfeld  distinguished  three 
kinds  of  autoinfection — first,  that  from  bacteria  in  the  genital  tract,  including  the 
vulva  (e.  g.,  gonorrhea),  whether  they  entered  the  tissues  themselves  or  were  intro- 
duced by  absolutely  sterile  fingers  or  instruments;  second,  that  transported  to  the 
genital  canal  via  the  blood  from  a  distant  site  of  suppuration,  such  as  the  tonsil, 
the  lungs,  a  mastitis;  and,  third,  the  infection  of  the  genital  canal  from  contiguous 
disease,  for  example,  apjicndicular  abscesses,  pyosalpinx,  pyelo-ureteritis.  To  this 
might  be  added  a  fourth,  the  inoculation  of  the  patient  by  herself  with  bacteria, 
either  present  on  her  hands,  or  carried  by  her  from  a  focus  of  suppuration,  for 
example,  ulcus  cruris,  tonsillitis,  a  sinus  disease,  otitis,  abscess  of  the  breast,  an 
intertrigo,  etc.  It  is  hard  to  differentiate  this  form  from  Ahlfeld's  second  fomi. 
With  Wegelius  and  Walthard  I  would  prefer  to  limit  the  term  autoinfection  to  those 
cases  where  the  bacteria  of  the  genital  tract,  including  the  vulva,  tlevelop  virulence 
and  invade  the  tissues,  or  produce  poisons  which  are  absorbed,  without  anj-  possible

external  agency.  It  is  better  to  exclude  from  this  definition  all  reference  to  the 
transference  of  infection  from  other  foci  in  the  l^ody,  as  well  as  the  admission  that 
the  even  aseptic  hand  may  introduce  the  bacteria  which  were  present  in  the  vagina 
into  the  puerperal  wounds. 

On  the  ground  of  clinical  experience  I  am  forced  to  admit  thefrequentoccurrence 
of  autoinfection,  in  the  broad  sense  that  Ahlfeld  holds,  and  in  the  narrow  definition 
just  proposed  it  also  occurs,  but  the  cases  are  very  few  in  number.  The  question 
has  held  the  attention  of  the  best  obstetricians  and  bacteriologists  of  our  time, 
and  innumerable  and  laborious  investigations  have  been  made,  but  the  results  were 
so  conflicting  that  its  solution,  until  within  a  few  years,  seemed  impossible.  Whether 
a  woman  may  or  may  not  be  infected  from  within  during  labor  depends  on  whether 
or  not  the  vagina  may,  under  the  usual  conditions  of  life,  the  woman  being  in  appar- 
ent health,  contain  pathogenic  bacteria.  Mention  of  only  a  few  who  took  part  in 
the  polemic  need  be  made — Doderlein,  Kaltenbach,  Ahlfeld,  Kronig,  ]\Ienge, 
Bensis,  Steffeck,  Vahle,  Walthard,  Winter,  Stroganoff,  and,  prominently  in  America, 
Williams,  of  Johns  Hopkins.  Kronig,  ]\Ienge,  and  Williams  believed  that  the 
vagina  of  apparently  healthy  women  contained  no  pj'ogenic  bacteria.  Walthard, 
Kaltenbach,  Ahlfeld,  Bumm,  Sigwart,  and  others  believed  that  it,  in  a  large  per- 
centage of  cases,  contained  many,  even  the  streptococcus.  Some  believe  that, 
given  favorable  conditions,  these  bacteria  could  become  very  virulent. 

The  latest  studies  by  Bumm,  Xatvig,  Wegelius,  Kronig  and  Pankow  (1909), 
and  Winter  (October,  1911),  employing  very  favorable  culture-media  (grape-sugar 
bouillon  and  blood-agar),  seem  to  prove  that  the  vaginas  of  apparently  healthy 
women  in  the  last  weeks  of  pregnane}^  contain  streptococci  and  staphylococci  in 
from  40  to  75  per  cent,  of  the  cases  examined,  and  that  these  bacteria,  while  usually 
living  a  saprophytic  existence,  may  wander  from  the  vulva,  the  vestibule,  the 
vagina,  up  into  the  uterus  or  into  the  wounds  during  the  puerperium  and  cause 
puerperal  fever.  From  general  practice  we  have  analogies  of  autoinfection  to  draw 
upon,  to  mention  only  two  examples,  the  acute  pelvic  peritonitis  of  virgins,  the  result 
of  "catching  cold"  or  refrigeration  during  the  menses  and  osteomj-elitis  in  children 
after  severe  exposure.  It  must  also  be  remembered  that  cats  and  domestic  animals 
have  puerperal  fever. 

On  the  vulva,  as  was  to  be  expected,  streptococci,  staphylococci,  Bacterium 
coli,  Bacillus  pseudodiphtheria?,  and  many  saprophytes  are  to  be  found,  and  espe- 
ciall}'  if  there  are  pustular  or  eczematous  eruptions  near  by.  In  the  urethra  the 
same  germs  vegetate.  In  cystitic  urine  the  same  and  the  Proteus  vulgaris,  wath 
others  still.  Ascending  ureteropyelitis  has  already  been  discussed,  and  germs  here 
present  may  be  dangerous  to  the  parturient  canal.  Even  in  apparently  normal 
women  bacteriuria  occurs,  and  the  streptococcus  (author),  the  colon  bacillus,  and 
typhoid  bacilli  have  been  demonstrated. 

In  the  vagina,  under  apparentl}^  normal  conditions,  the  following  l^acteria  have 
been  demonstrated  (Walthard,  Bar,  and  Wegelius) : 

(1)  Facultative  anaerobic  streptococci  of  the  type  of  the  Streptococcus  pyo- 
genes puerperalis.  (2)  Facultative  anaerobic  streptococci  of  the  type  of  the  Diplo- 
streptococcus  puerperalis.  (3)  Obligate  anaerobic  streptococci  of  the  type  of  the 
Streptococcus  anaerobius.  (4)  Staphylococci  of  the  type  of  the  Staphylococcus 
pyogenes  liquefaciens,  albus,  aureus,  and  citreus.  (5)  Bacterium  coli.  (6)  Gono- 
coccus.  (7)  Bacillus  funduliformis.  (8)  Pseudotetanus  bacillus.  (9)  Bacillus 
aerogenes  capsulatus  (Welchii),  (10)  Bacillus  vaginalis  (Doderlein).  (11)  Bacte- 
rium pseudodiphtherise.  (12)  Gram-positive  cocci,  diplococci,  bacilli,  and  diplo- 
bacilli.  (13)  Micrococcus  tetragenus.  (14)  Saccharomyces.  (15)  Bacillus  of 
Weeks.  (16)  Bacillus  bifidus  communis.  (17)  Various  other  anaerobic  and  aero- 
philic  cocci  and  bacilli  and  streptobacilli. 

Doderlein   distinguishes  two   forms   of  vaginal   secretion — normal,  which   is 


PUERPERAL   INFECTION  823 

white,  like  curdled  milk,  acid,  contains  no  mucus,  and  is  small  in  amount;  and 
pathologic,  which  is  thick,  yellowish  or  greenish  mucus,  sometimes  foamy,  usually 
alkaline,  but  not  necessarily  so,  and  contains  numerous  pathogenic  and  non-patho- 
genic microorganisms,  whereas  the  normal  vaginal  secretion  contains  only  the 
Bacillus  vaginse,  a  harmless  organism.  It  is  certain  that  the  pathologic  discharges 
contain  more  of  the  mentioned  organisms  than  do  the  normal,  but  it  is  not  easy 
to  divide  the  cases  sharply  into  two  classes  either  clinically  or  bacteriologically. 

The  closed  cervix  is  infected  in  its  lower  third,  the  mucous  plug  here  being 
cloudy  yellow,  showing  the  presence  of  pus  and  bacteria.  It  is  white  in  the  next 
zone  and  clear  in  the  upper  part,  being  here  aseptic.  Under  normal  conditions,  ac- 
cording to  the  recent  researches  of  Winter,  Menge,  and  Walthard,  the  uterine  ca\'ity 
is  sterile,  but  it  may  harbor  bacteria,  and  they  then  live  in  the  decidua  and  fetal 
membranes.  Usually  they  do  not  go  through  the  villi  to  the  fetus,  but  pass  through 
the  membranes  into  the  liquor  amnii,  thence  to  the  blood  of  the  fetus  through  the 
stomach,  and  thus  to  the  capillaries  in  the  villi.  Bacteria  may  also  get  to  the  fetus 
through  the  villi,  having  reached  the  interxnllous  spaces  via  the  maternal  blood — for 
example,  the  pneumococcus  and  the  typhoid  bacillus  in  corresponding  infections. 

Since  the  bacteria  mentioned  exist  in  the  genital  tract  of  the  gra\dda,  and  are 
there  even  during  labor,  why  does  not  every  woman  become  infected?  First,  they 
live  as  saprophytes,  requiring  special  conditions  to  develop  invasive  qualities  or 
virulence.  We  have  several  analogies.  In  the  mouth  and  nose  the  streptococcus, 
the  pneumococcus,  the  diphtheria  bacillus,  and  the  staphylococcus  may  live  harm- 
lessly, and  only  mider  extraneous  influence  cause  sickness,  but  they  may  be  infec- 
tious for  others.  In  the  intestinal  canal  the  Bacillus  coli  and  other  bacteria  exist 
under  the  same  conditions.  In  the  horse  the  tetanus  bacillus,  very  fatal  if  inocu- 
lated into  a  Avound,  lives  as  a  harmless  parasite.  Second,  the  vagina  has  some  power 
of  purification,  at  least  it  has  f|ualities  which  ordinarily  keep  the  actiA^ties  of  its 
flora  within  safe  bounds — in  a  way  similar  to  that  of  the  mouth.  Doderlein  ascribed 
this  power  to  the  lactic  acid  produced  by  the  Bacillus  vaginse,  which  makes  the 
vaginal  secretion  unsuitable  for  the  growi:h  of  other  bacteria.  Menge  believed  that 
phagoc}i;osis  going  on  in  the  cervix  and  vagina  had  something  to  do  A^nth  it.  Per- 
haps other  immunizing  forces  are  at  work  to  produce  local  cell  immunity,  and  the 
process  will  be  explained  when  the  biochemical  studies  in  immunity  of  IMetchnikoff, 
v.  Behring,  Ehrlich,  and  others  are  carried  to  completion.  Third, during  labor  there 
are  the  mechanical  scouring-out  of  the  bacteria,  the  flow  of  the  liquor  amnii,  and  the 
outpouring  of  mucus  and  blood,  and  the  passage  of  the  child  and  placenta,  which 
remove  large  numbers  of  bacteria.  Fourth,  newly  let  blood  has  antitoxic  properties 
for  a  short  time.  Investigations  of  the  lochia  (vide  infra)  in  the  first  forty-eight  hours 
have  showTi  very  few  bacteria,  while  on  the  third  day  the  increase  is  marked,  but  by 
this  time  the  wounds  have  closed,  a  bank  of  granulations  has  been  throwTi  up, 
through  Avhich  the  bacteria  may  not  easily  break,  excepting  the  virulent  strepto- 
coccus and  the  gonococcus,  and  the  cervix  has  closed,  shutting  off  the  uterine  cavity 
more  or  less.  Fifth,  the  downward  and  outward  current  of  the  lochia  and  the  mucus 
covering  the  surface  must  also  be  considered.  It  is  important  for  the  accoucheur 
to  bear  these  things  in  mind,  so  that  he  does  not  interfere  with  nature's  methods  of 
protecting  the  puerperal  woman,  and,  as  we  know,  these  methods  are  very  suc- 
cessful. 

Natvig  and  Wegelius  have  sho^Ti  that  the  flora  of  the  vagina  in  the  puerperium 
is  the  same  as,  or  at  least  very  similar  to,  that  of  the  vulva,  vestibule,  and  vagina 
before  labor,  and  many  of  the  bacteria  mentioned  on  p.  821  have  been  demonstrated 
in  the  lochia  of  fever-free  puerpera^.  Thereforethe  bacteria  havethepowerto  wander 
into  and  up  the  genital  tract.  In  three-fourths  of  the  cases  examined  the  bacteria 
were  found  in  the  uterus  itself  on  the  fourth  daj-.  They  were  few  in  number,  and 
almost  always  all  obligate  anaerobes,  the  facultatives  being  lightly  represented. 


824  PATHOLOGY    OF    THE    PIERPEKIIM 

On  till*  ninth  ilay  90  per  rent,  of  the  cases  showed  bacteria  in  considera])le  number, 
but  tliey  were  ahnost  entirc^ly  obhgate  anaerol)es,  only  once  in  ten  cases  a  faculta- 
tive anaerobic  streptococcus  being  met.  In  spite  of  all  this,  if  the  woman  is  not 
molested  by  meddling  accoucheurs,  she  will  almost  always  recover  from  her  labor 
by  grace  of  the  immunities  provided  by  nature,  and  while  mild  cases  of  autoinfection 
may  occur  occasionally,  fatal  cases  are  exceedingly  rare.  The  practical  lesson  to 
be  learned  from  these  investigations  is  that  the  accoucheur  should  studiously  and 
consistently  avoid  those  conditions  which  render  these  bacteria  virulent  and  in- 
vasive, and  which  carry  them  to  regions  of  the  parturient  canal  where  they  may  un- 
fold their  latent  powers.  Conditions  favoring  autoinfection  are  excessive  bruising 
of  the  parts  from  prolonged  labor,  great  delay  in  delivery  after  rupture  of  the  mem- 
branes, the  retention  of  pieces  of  placenta  in  the  uterus,  or  membranes  which  hang 
down  into  the  vagina  and  form  a  bridge  on  which  the  bacteria  may  mount  into  the 
uterus,  or  blood-clots  in  the  vagina,  lochiometra,  and  lochiocolpos. 

Hetero-infection.— Infection  from  without — exogenous  infection — is  by  far  the 
most  common,  and  is  always  first  to  be  thought  of  when  a  puerpera  develops  fever. 
Infection  may  be  brought  to  the  genital  tract  from  the  outside  in  many  ways: 

(1)  The  most  common  carrier  is  the  physician  or  midwife,  rarely  the  nurse.  The 
finger,  or  an  instrument  insufficiently  sterilized,  introduced  into  thegenitalia,  deposits 
virulent  germs  in  the  tissues.  These  germs  have  been  brought  from  a  case  of  puer- 
peral sepsis,  from  the  dressing  of  an  ulcer,  or  any  suppurating  or  infected  wound, 
from  a  postmortem,  an  erysipelas  case,  a  cancer,  pneumonia,  tyjahoid,  scarlet  fever, 
diphtheria,  from  a  baby  with  infected  umbilicus  or  enteritis,  etc.,  from  the  lochia  of 
even  normal  puerperse,  or  even  the  ordinary  filth  under  the  finger-nails.  The  bacteria 
attain  great  virulence  by  ''passage"  through  a  human  being.  The  attendant  may 
have  the  focus  of  infection  on  his  own  person — a  felon  on  the  finger,  furunculosis, 
a  wet  eczema  (they  often  contain  streptococci),  tuberculosis,  ozena  (as  the  famous 
case  of  Dr.  Rutter,  of  Philadelphia,  in  the  forties),  an  acute  rhinitis,  or  a  pharyngitis. 
A  small  epidemic  in  the  dispensary  service  of  the  Chicago  Lying-in  Hospital  orig- 
inated from  the  throat  of  an  intern.  In  the  discharges  from  the  nose  a  hemolytic 
aerobic  streptococcus  was  found  in  almost  pure  culture.  Some  years  ago  a  local 
hospital  suffered  an  epidemic  of  fatal  post-operative  peritonitis,  and  a  virulent 
streptococcus  was  isolated  from  the  throats  of  many  of  the  nurses  and  interns,  as 
well  as  from  the  dust  in  the  wards  and  operating-rooms.  Schatz  ol^served  two 
puerperal  fever  epidemics  of  similar  origin.  In  these  cases  the  bacteria  get  onto 
the  hands,  instruments,  or  sponges,  and  are  thus  carried  into  the  genitals,  or  they 
are  expectorated  directly  onto  and  into  the  vulva  and  puerperal  wounds,  or  they 
settle  on  them  from  their  suspension  in  the  air  as  droplets  or  as  dust  (vide  infra). 

(2)  The  environment  has  much  to  do  with  the  causation  of  puerperal  infection, 
and  the  author  must  here  express  a  change  of  opinion  from  that  held  in  1898.  In 
my  mind  there  is  now  no  doubt  but  that  many  cases  of  puerperal  fever  are  due  to 
the  infected  dust  and  air  of  hospitals  and  other  places  where  the  birth  occurs. 
Bacteria  from  puerperal  cases,  from  the  dried  pus  of  suppurations,  from  the  autopsy 
room,  the  pathologic  laboratory,  and  from  the  innumerable  sources  of  infection  of  a 
general  hospital,  get  into  the  air  and  the  dust,  and  are  carried  by  air-currents  or 
persons  to  all  parts  of  the  institution,  including  the  delivery-room  and  the  lying-in 
chambers.  The  infection-laden  dust  settles  on  the  sterilized  tables,  the  towels,  the 
hand  solutions,  and  on  the  vulva.  From  here  the  bacteria  are  carried  into  the  va- 
gina by  sterilized  and  gloved  fingers,  the  instruments,  gauzes,  etc.  Or  they  settle 
on  the  bed-clothing  of  the  puerpera  and  thus  come  in  direct  contact  with  the  patu- 
lous vulva,  whence  they  wander  up  into  the  uterus.  The  staphylococcus  is  almost 
always  found  in  the  air  of  closed  rooms  where  people  congregate,  but  in  hospitals 
other  bacteria  also  are  found. 


PUERPERAL   INFECTION  825 

The  author  does  obstetric  work  in  four  ficncral  hospitals  having  more  or  less  isolated  mater- 
nity wards,  in  the  Chicago  Lying-in  Hospital,  which  accejjts  only  maternity  cases,  and  in  the 
homes  of  the  patients.  Gloves,  sterilized  by  himself,  are  used  in  all  these  cases,  and  thetechnic 
employed  at  all  the  places  is  practically  identical.  Over  twice  as  many  fever  cases  are  observed 
in  the  general  hospitals  as  are  found  in  cases  treated  at  the  Chicago  Lying-in  Hospital  and  in  the 
homes.  In  one  case  an  almost  fatal  staphylococcous  ])uerperal  infection  occurred  in  a  patient 
occupying  a  room  just  vacated  by  a  man  suffering  with  a  suppurating  knee.  The  children  al.so 
show  the  etTect  of  the  general  prevalence  of  infectious  material.  In  the  general  hospitals  marked 
rises  of  temperature  on  the  third  to  si.xth  day  are  obs(!rved  in  a  proportion  reaching  at  times  30 
per  cent,  of  the  infants,  while  in  the  other  places  a  temperature  in  the  child  is  a  great  rarity.  In 
one  of  the  general  hospitals  two  epidemics  of  sepsis  carried  away  lo  children;  in  another  2  died 
from  sepsis,  probably  pharyngeal  in  origin.     Intestinal  infections  are  very  common. 

In  discussing  the  mortality  and  morbidity  of  obstetric  institutions  the  condition  of  the 
children  should  be  giv(>n  more  consideration — the  new-born  child,  so  to  speak,  is  a  sterile  medium, 
and  much  more  sensitive  to  infection  than  gelatin  and  agar. 

Werth,  and  Schroder  in  Kiel,  noticed  an  increase  in  fever  cases  of  women  tiol  examined 
in  labor  during  the  prevalence  of  a  puerperal  fever  epidemic  in  the  institution.  Winter 
regards  as  dangerous  even  an  apparently  healthy  gravida  who  has  hemolytic  streptococci  in  the 
vaginal  secretions,  and  isolates  her  as  a  "carrier."  Semmelweis  recognized  the  danger  of  air- 
borne infection,  and  describes  an  incidi-nt  where  six  of  the  women  in  a  ward  containing  a  puerpera 
wnth  an  ichorous  tubercular  knee  died  of  child-bed  fever.  Another  epidemic  was  maintained  by 
imperfectly  washed  bed-sheets.  Zweifel  reported  in  1911  a  series  of  deaths  due  to  the  opening  of 
a  stinking  abscess  in  his  operating-room.  Bumm  (1912)  reports  a  long  endemic  originating  from 
a  septic  parturient.  Hektoen  and  Kirschsteiner  have  shown  that  the  streptococcus  and  staphylo- 
coccus will  live,  dried  in  the  air,  exposed  to  diffu.sed  daylight,  from  eighteen  hours  to  ten  days,  and 
in  dark  cellars  over  a  month.  This  in  itself  is  sufficient  proof  that  open  wounds,  such  as  puer- 
peral present,  are  likely  to  become  infected  by  germs  carried  bj'  air-currents,  in  ventilating  flues, 
or  in  swirling  dust  from  one  part  of  the  hospital  to  another.  Schauta,  Chrobak,  Leopold,  Bumm, 
Tarnier,  Pinard,  Florence  Nightingale,  Walthard,  Zweifel,  and  others,  believing  these  things,  de- 
mantl  separate  confinement  rooms  ancl  lying-in  rooms  for  septic  cases.  Mackenrodt  in  1912  held 
that  air  infection  is  possible.  Space  does  not  permit  apresentmentof  themany  furtherproofs,  from 
my  own  experience,  of  the  dangers  of  air,  dust,  and  indirect  contact  infection  in  general  hospitals. 

(3)  The  preparatory  bath  before  deUvery  may  be  a  source  of  danger.  In  a 
general  way  the  water  is  not  infectious.  In  Philadelphia,  some  years  ago,  an  epidemic 
of  tetanus  was  probably  due  to  the  use  of  unboiled  Schuylkill  water.  Chicago  water 
contains  all  kinds  of  bacteria,  but  Gehrman  says  he  has  never  found  the  strepto- 
coccus in  it. 

Stroganoff  proved  that  the  bath- water  obtained  access  to  the  vagina  when,  as 
in  multiparse,  the  vulva  gapes  more  or  less,  and  other  laborious  investigations  have 
been  made.  The  question  can  be  very  simplj'  decided  by  asking  muciparous  women 
whether  the  bath-water  enters  the  vagina.  ^lost  of  them  answer  in  the  affirma- 
tive; therefore  the  scales  of  epithelium  and  soil  from  the  whole  body,  mixed  with 
the  water,  and  some  of  the  bacteria,  must  gain  entrance  to  the  vagina.  If  a  woman 
has  an  ulcer  or  other  suppuration  on  her  body,  the  danger  is  greatest.  In  such  cases 
the  general  bath  should  be  forbidden.  Bumm,  when  in  Halle,  reported  two  cases 
of  .severe  vulvar  streptococcus  infection  occurring  from  baths  in  a  tub  in  which  old 
culture  tubes  of  the  streptococcus  had  been  washed.  That  puerperal  infection  can 
be  carried  from  one  patient  to  another  on  the  bed-pan,  douche-points,  etc.,  is  a 
fact  known  since  before  Semmelweis, 

(4)  The  husband  as  a  source  of  infection  has  not  been  sufficiently  recognized. 
Among  the  lowest  classes  coitus  in  the  latter  weeks  of  gestation  is  by  no  means  rare, 
and  it  has  been  performed  even  during  labor,  Kisch  refers  to  the  practice  of  cer- 
tain midwives  who  ask  the  husband  to  have  intercourse  with  the  parturient  to 
stimulate  the  labor  pains.  In  one  of  the  fatal  cases  of  sepsis  in  the  dispensary 
service  of  the  Chicago  Lying-in  Hospital  the  Ixig  of  waters  was  ruptured  l)y  the  act, 
and  the  child  was  l)orn  before  the  arrival  of  the  physician.  In  another  coitus  was 
performed  thrice  during  the  night,  pains  beginning  at  3  a.  m.  and  deliver}-  being 
completed  at  11  a.  m.  Lustgarten,  Wassermann,  and  others  have  showTi  that  the 
streptococcus  vegetates  in  the  urethra  of  healthy  men,  Asacura  finding  it  in  12.5  per 
cent,  of  112  cases,  and,  further,  the  staphylococcous  group  and  pseudodiphtheria 
bacilli  are  often  found.  In  the  diseased  urethra  streptococci,  pyococci,  diplococci 
(Gram-negative),  gonococci.  Bacterium  coli,  and  cocci  which  resemble  the  Diplo- 


826  PATHOLOGY  OF  THE  PUERPERIUM 

streptococcus  puerperalis  have  been  found.  Entirely  apart  from  the  finding  of 
bacteria  in  the  urethra,  it  is  certain  that  the  penis  is  never  sterile,  and,  if  it  were,  it 
would  carry  in  bacteria  from  the  vulva. 

(5)  The  patient  herself  may  carry  infection  to  the  genitalia  on  her  fingers.  I 
have  seen  severe  and  even  fatal  puerperal  disease  result  from  a  carbuncle  on  the  neck 
(a  precipitate  labor),  a  running  ear  (a  streptococcous  infection  following  influenza), 
ulcus  cruris,  a  paronychia,  and  there  are  on  record  authentic  instances  of  the  trans- 
portation, by  the  patient,  of  virulent  organisms  from  other  distant  parts  of  the  body 
to  the  genitals,  for  example,  from  the  purulent  cavity  of  an  artificial  eye,  from  a 
weeping  eczema,  a  mastitis,  an  intertrigo.  How  often  in  such  cases  the  germs  are 
carried  by  the  blood-stream  to  the  puerperal  wounds,  instead  of  by  the  hands,  can- 
not be  determined.  It  seems  probable,  in  several  reported  cases  of  tonsillar 
abscess,  in  influenza,  erysipelas,  scarlatina,  and  pneumonia,  that  the  infection  was 
thus  transmitted. 

A  suppurating  or  inflammatory  focus  in  or  near  the  genital  tract  is  often  a  source 
of  danger.  In  my  own  experience  a  vaginal  abscess  which  ruptured  during  delivery 
caused  an  extensive  bilateral  parametritis;  an  appendix  adherent  to  the  tube  caused 
a  fatal  endometritis  and  bacteremia;  a  gonorrheal  vaginitis,  late  infection  and  pyo- 
salpinx;  a  non-gonorrheal  vaginitis,  an  endometritis  saprophytica  with  toxinemia; 
a  recto-uterine  fistula,  fatal  peritonitis;  a  gangrenous  myoma,  a  severe  toxinemia; 
infected  urine  (streptococcus),  septicemia  and  double  phlegmasia  alba  dolens. 
Cases  are  reported  of  puerperal  fever  from  ruptured  appendiceal  abscesses,  from 
cystitis,  from  bartholinitis  (gonococcus  and  streptococcus),  from  cancer  of  the 
uterus,  from  eczema  and  intertrigo  pudendi,  from  enterocolitis  (streptococcus  and 
Bacterium  coli).  It  must  be  added  that  many  women  affected  with  the  diseases 
mentioned  above  go  through  labor  without  the  development  of  infection,  it  being 
the  case  that  the  woman's  local  and  general  immunities  have  been  sufficiently  devel- 
oped to  repel  the  invading  microorganisms. 

Predisposing  Causes. — (1)  Pregnancy  itself  favors  the  attack  of  bacteria, 
which  is  perhaps  explained  by  the  changes  in  the  liver,  in  the  kidneys,  and  the 
demineralization  of  the  tissues.  Animals  are  more  sensitive  to  infection  at  this 
time.  (2)  The  shock  of  labor,  which  is  really  a  surgical  operation,  comprising  the 
making  of  wounds,  many  of  which  are  contused,  and  the  bruising  of  the  peri- 
toneum, lowers  the  vital  resistance.  (3)  All  conditions  which  reduce  the  vitality, 
as  profuse  hemorrhages,  eclamptic  toxemia,  coincident  affections,  as  typhoid, 
pneumonia,  grip,  syphilis,  cardiopathies,  alcoholism,  overwork,  hunger,  mal- 
nutrition, etc.  (4)  Lack  of  thyroid  or  action  of  other  blood-forming  glands 
may  be  operative.  (5)  Prolonged  labor,  especially  after  the  rupture  of  the  bag  of 
waters,  because' of  the  frequent  vaginal  explorations,  and  the  greater  time  and 
opportunity  for  bacteria  to  wander  upward,  increases  both  the  frequency  and  the 
severity  of  the  infections.  Demelin,  in  513  cases,  has  shomi  that,  as  the  time  elaps- 
ing increased  from  twelve  hours  to  five  days,  the  percentage  of  infections  increased 
from  0.8  to  11.26  per  cent.  The  bad  influence  of  exhaustion  deserves  repetition 
here.  (6)  Operative  interference,  because  of  the  wounds,  contusions,  and  the  bacteria 
introduced  from  without,  increases  both  morbidity  and  mortality.  Too  early  rup- 
ture of  the  bag  of  waters  acts  in  this  way;  the  hard  head  tears  the  cervix  instead  of 
dilating  it  softly,  and,  besides,  dry  labors  often  have  to  be  terminated  instru- 
mentally.  (7)  Retention  of  pieces  of  placenta,  of  membranes,  and  of  blood-clots 
favors  infection,  the  most  dangerous  being  the  placental  remnants.  The  glycogen 
and  peptones  of  the  involuting  uterus  produce  favoring  cultural  conditions.  Lochial 
retention  causes  fever,  but  is  seldom  continued  long  (niough  to  cause  real  sickness. 

The  author  has  gone  rather  fully  into  the  etiology  of  puerperal  fevers,  mainly 
with  the  view  to  pointing  out  a  rational  prophylaxis. 

Reaction  of  the  Organism  Against  Injection. — Very  properly  the  whole  parturient 


PUERPERAL    INFECTION  827 

canal  is  regarded  as  a  wounded  surface  after  delivery,  and  healing  takes  place  in  the 
manner  of  ordinary  surgical  wounds.  The  endometrium  is  more  or  less  covered  by 
a  layer  of  necrosing  dccidua,  but  the  ends  of  the  septa  between  the  glands  are 
partly  exposed,  and  when  the  decidua  falls,  they  are  fully  exposed,  but,  fortunately, 
at  this  time  they  are  protected  by  the  bank  of  leukocytes  beneath  the  surface. 
Under  the  necrosing  decidua  an  active  leukocytosis  occurs,  the  connective-tissue 
cells  increase  in  numbers,  plasma  cells  are  thrown  out,  all  of  which  prevents  the 
invasion  of  all  but  the  most  virulent  bacteria,  and,  at  the  same  time,  aids  in  the 
casting  off  of  the  dead  decidua.  By  the  sixth  day,  in  normal  cases,  epithelization  is 
usually  complete,  except  at  the  placental  site.  Here  the  thrombi  in  the  open  vessels 
require  more  time  and  different  methods.  The  placental  site  is  rough  and  raised; 
often  is  covered  with  irregular  masses  of  thick  decidua,  tough  fibrin,  and  sometimes 
even  shreds  of  placenta  or  bits  of  villi.  Organization  occurs  in  the  thrombotic 
sinuses;  the  bank  of  granulations  thickens  and  causes  the  exfoliation  of  the  super- 
imposed foreign  masses.     This  may  require  two  weeks. 

The  effect  of  bacteria  on  these  healing  processes  varies  with  the  nature  of  the 
microorganism  and  the  manner  in  which  it  is  introduced. 

If  the  germs  are  saprophytic, — that  is,  without  invasive  qualities, — they  may 
not  disturb  the  healing  process  at  all;  at  most,  if  they  produce  caustic  toxins,  super- 
ficial necrosis  results.  Blood-clots,  decomposing  bits  of  membrane  and  of  placenta, 
and  dead  or  injured  tissues  harbor  saprophytic  bacteria.  Without  doubt  the  toxins 
they  develop  can  produce  cloudy  swelling,  even  necrosis  of  the  uppermost  layers  of 
cells,  and  these  toxins  may  be  absorbed  into  the  blood,  the  vagina  and  the  uterus 
postpartum  being  actively  resorptive.  Since  some  bacteria  produce  ptomains  and 
alkaloids,  for  example,  sepsin  and  putrescin,  these  may  likewise  be  absorbed.  Under 
the  necrotic  layer  a  bank  of  leukocytes  limits  the  further  advance  of  bacteria.  All 
this  is  very  superficial,  and  even  sutured  wounds  heal  in  the  depths — ^just  the  edges, 
being  exposed  to  the  noxa,  may  be  slightly  affected.  More  or  less  pus  is  formed  on 
the  surface,  and  its  discharge  continues  until  all  the  dead  tissue  is  removed.  Symp- 
toms, if  there  are  any,  are  due  to  the  toxins — and  few  bacteria — absorbed,  and  the 
condition  is  called  toxinemia.     Duncan  named  it  sapremia. 

If  the  bacteria  are  pyogenic,  but  without  marked  invasive  qualities,  they  go  a 
little  deeper  into  the  tissues  and  the  wound  reaction  is  greater.  Owing  to  the  favor- 
ing conditions  of  the  puerperal  tissues,  the  succulence,  the  bruising,  with  lowered 
vitalit}',  and  the  presence  of  peptone  and  glycogen  from  the  involuting  uterus,  the 
bacteria  rapidly  multiply.  Their  presence  and  their  toxins  cause  a  dilatation  of  the 
local  blood-vessels,  and  by  a  positive  chemotaxis  phagocytes  and  leukoc^^tes  are 
crowded  into  the  neighborhood  of  the  invaders,  and  exudations  rich  in  poljaiior- 
phonuclears  and  eosinophiles,  plasma  cells,  and  lymphocytes  are  thrown  out. 
Gradually  the  fixed  connective-tissue  cells  and  the  leukocytes  form  a  firm  bank  or 
granulation  wall,  which  resists  the  further  advance  of  the  bacteria  and  prevents  the 
absorption  of  their  poisons.  This  granulation  wall  is  composed  of  polynuclear  and 
mononuclear  leukocytes,  eosinophiles,  fibroblasts,  and  polyblasts.  Absence  or 
paucity  of  the  multinuclear  neutrophiles  and  the  eosinophiles,  with  increase  of  the 
mononuclears,  indicates  poor  tissue  reaction  (Adami). 

Bacteria  produce  poisons  which  may  be  soluble,  leaving  the  body  of  the  cell, 
or  fixed  in  the  body  of  the  cell,  lieing  liberated  when  the  germ  dies  or  is  broken  up. 
The  former  are  called  exotoxins;  the  latter,  endotoxins.  Toxins  may  be  met  and 
neutralized  by  antitoxins  already  existent  in  the  body  or  produced  for  the  occasion. 
Endotoxins  are  not  thus  gotten  rid  of.  It  is  believed  that  the  bacteria,  laden  with 
poisons, — e.  g.,  aggressins, — are  met  by  certain  substances  in  the  blood-serum  which 
cause  the  dissolution  of  the  bacteria  (lysins),  or  agglutinate  them  (agglutinins),  or 
so  weaken  them  that  they  maybe  successfully  attacked  by  the  phagocytes  (opsonins). 
It  must  be  remembered  that,  in  addition  to  the  poisons  made  by  the  bacteria,  the 


828  PATHOLOGY  OF  THE  PUERPERIUM 

by-products  of  the  decomposition  of  the  protein  of  the  cells,  ptomains  and  leuko- 
mains,  may  be  absorbed.  All  these  cellular,  biochemic  processes  may  be  limited  to 
the  region  around  the  site  of  entrance  of  the  infective  organisms.  The  outpouring  of 
lymph  may  be  large,  the  leukocytosis  marked,  and  the  swelling,  therefore,  be  great, 
and  all  the  classic  signs  of  intiammation  may  b(>  present.  Here  it  may  be  best  to 
emphasize  the  chfference  between  infection  and  inflannnation.  Inflammation  is  the 
reaction  of  the  tissues  against  the  invasion  of  the  noxious  elements,  and  is  nature's 
attempt  at  defense  and  repair.  If  the  tissues  and  leukocytes  are  much  injured  by  the 
to.xins  of  the  bacteria,  or  if  their  nutrition  is  cut  off  by  the  plugging  of  the  capillaries, 
local  necrosis — pus-formation — occurs.  If  not,  the  poisons  are  neutralized,  the 
exudates  are  reabsorbed,  the  bacteria  dissolved  or  removed  by  the  leukocytes,  which 
also  help  remove  the  phagocytes  killed  in  battle,  and  the  fixed  connective-tissue 
cells  organize  into  more  or  less  permanent  fibrous  tissue,  leaving  scars.  During  all 
this  process  toxins — and  a  few  l^acteria — get  into  the  blood,  producing  general  symp- 
toms— fever,  rapid  heart,  prostration,  etc.  The  process  is,  however,  quite  local, 
and  the  condition  is  still  called  toxinemia. 

If  the  invasive  power  of  the  bacteria  is  very  great,  a  quality  of  certain  strains 
of  streptococcus,  even  the  intact  vagina  may  not  be  able  to  withstand  the  attack. 
The  streptococcus'  aggressins  drive  away  the  leukocytes,  and  itself  quickly  invades 
the  lymph-vessels,  into  the  subcutaneous  and  submucous  tissues,  multiplying  rapidly. 
Within  an  hour  after  inoculation  (some  say  a  few^  minutes)  it  is  beyond  the  reach 
of  the  most  powerful  antiseptic,  and  the  result  to  the  patient  depends  on  her  power 
of  resistance.  The  battle  between  the  streptococcus  and  its  toxins — streptocolysin, 
leukocidin,  etc.,  with  the  patient's  leukocytes,  and  immune  bodies,  alexins,  etc. — 
is  soon  transferred  to  the  blood  itself,  and  a  real  bacteremia  occurs.  (It  is  pos- 
sible, in  a  text-book  of  this  nature,  only  to  indicate  the  processes  involved.  For 
full  information  the  reader  is  referred  to  works  on  immunity  and  general  pathology, 
such  as  those  of  Ricketts  and  Adami.) 

The  Streptococcus  pyogenes,  cUscovered  by  Mayerhofer  in  1865,  cultivated  by 
Pasteur  in  1879  from  the  blood  of  women  dying  from  puerperal  fever,  and  isolated 
in  pure  culture  by  Ogsten,  in  1883,  is  the  cause  of  the  majority  of  the  cases  of  infec- 
tion'after  childbirth.  It  gains  entrance  at  any  point  of  the  parturient  canal,  passes 
at  once  into  the  lymph-spaces  and  along  the  capillaries  into  the  blood-stream,  with- 
out producing  much  local  reaction.  Serous  and  scropurulent  exudate  may  be  slight 
or  much,  depending  on  the  virulence  of  the  invader.  The  streptococcus,  unless 
of  minimal  virulence,  does  not  produce  solul^le  toxins,  but  its  body  contains  hemo- 
lysin and  leukocidin,  although  the  actual  toxic  agent  is  unknown.  Various  forms 
of  streptococci — the  Streptococcus  longus,  S.  brevis,  S.  erysipelatis,  S.  capsulatus — 
are  the  result  of  different  cultural  conditions  within  and  without  the  body.  Hemo- 
lysis is  not  a  constant  characteristic,  and  does  not  indicate  excessive  virulence,  nor 
does  the  length  of  the  chains,  although  usually  the  long  chains  are  the  most  danger- 
ous. As  was  already  stated,  the  streptococcus  may  be  found  in  the  vagina  of  many 
apparently  healthy  women.  It  exists  in  a  state  of  very  low  virulence  as  a  sapro- 
phyte. By  proper  cultural  treatment  it  may  be  made  very  active  and  extremely 
pathogenic  for  animals.  We  have  an  analogon  in  the  case  of  the  human,  when  strep- 
tococci, made  virulent  ])y  "passage"  through  one  puerpera,  are  introduced  into  the 
genitals  of  another,  there  causing  a  violent  infection,  or  when  they  are  carried  from 
the  inflamed  nose  or  throat  of  an  attendant  to  the  puerperal  wounds.  All  forms  of 
puerperal  infection,  from  a  simple  toxinemia  from  retained  lochia  to  the  bacter- 
emias which  may  be  fatal  in  a  few  hours,  may  be  produced  by  the  streptococcus. 
Wliich  it  shall  be  depends  on  the  natural  strength  of  the  inoculated  coccus,  the 
natural  resistance  of  the  patient,  the  number  of  the  bacteria  introduced,  the  con- 
comitant injury  of  the  tissues,  the  location  of  the  point  of  entrance,  and  the  time  of 
the  infection.     Severe  disease  will  result  if  only  a  few  chains  of  a  highly  invasive 


PUERPERAL    INFECTION  829 

organism  arc  introclucod,  or  if  the  woman's  resistance  happens  to  be  very  low  at  the 
time,  as  by  hemorrhage,  shock,  renal  or  hepatic  disease,  etc.  If  the  tissues  are 
much  bruised  by  labor,  they  are  not  in  condition  to  resist  invasion  by  even  a  mild 
streptococcus.  If  the  germs  are  deposited  near  the  peritoneal  cavity,  for  example, 
in  a  deep  cervix  tear,  or  on  the  thrombi  of  the  placental  site,  dangerous  infections, 
peritonitis,  and  metrophlebitis  are  more  apt  to  follow  than  if  they  were  inoculated 
into  a  perineal  laceration.  If  the  inoculation  occurs  late  in  the  puerperium,  the 
lymph-vessels  are  quite  closed,  the  blood-vessels  sealed,  the  local  immunities  well 
developed,  and  the  surface  well  protected  by  a  grarmlation  wall — all  of  which  pre- 
serves the  patient  from  invasion.  The  severest  fevers  result  from  direct  inoculation 
of  the  endometrium  and  placental  site  during  laljor  itself. 

The  staphylococcus  was  separated  from  the  streptococcus  by  Ogsten  in  1883  in 
purulent  affections.  Doleris  found  it  in  1880,  and  Brieger,  in  1888,  demonstrated 
the  Staphylococcus  aureus  in  five  fatal  cases  of  puerperal  infection.  All  the  staphy- 
lococcus group — Staphylococcus  aureus,  albus,  fiavus,  and  citreus — have  been  found 
in  these  cases,  and  occasionally  one  or  the  other  is  associated  with  the  streptococcus 
(Bar,  Tissier,  the  author).  ]\leml)ers  of  the  staphylococcus  group,  called  briefly 
pyococci,  are  less  invasive  than  the  streptococcus.  They  elicit  marked  leukocytosis, 
but,  possessing  leukocidin  and  proteolytic  ferment,  they  kill  the  leukocytes  and 
liquefy  the  tissues,  producing  pus.  Thej^  produce  soluble  toxins,  hemolysin  and 
leukocidin,  and  true  exotoxins,  which  elicit  the  antitoxins  of  the  lilood,  but  the  viru- 
lence of  the  germ  depends  not  on  these,  and  since  an  endotoxin  has  not  been  de- 
monstrated, again  we  are  at  a  loss  to  explain  their  toxicity.  Local  and  general 
leukocytosis  characterizes  infections  with  this  bacterium,  and,  contrary  to  a  general 
belief,  severe  and  fatal  puerperal  fever  can  be  caused  by  it,  as  one  of  my  cases  proved, 
although  this  is  unusual. 

Pyococci  are  found  on  every  vulva  and  in  most  vaginas  before  and  during  the 
puerperium,  but  they  live  as  harmless  parasites,  unless  their  virulence  is  exalted 
by  accidental  conditions.  They  may  cause  suppuration  in  perineorrhaphies,  non- 
union of  cervix  tears,  and  are  responsible  for  many  cases  of  parametric  abscesses 
and  of  slow  pyemia,  but,  as  was  said,  they  may  cause  any  of  and  all  the  forms  of 
puerperal  fever  which  the  streptococcus  can  produce.  The  organism  reacts  against 
invasion  of  the  pyococcus  by  phagocytosis,  and  by  means  of  antibacterial  products 
present  in  the  serum,  and  thro^\^l  ofT  by  the  leukocytes,  w^hich  are  perhaps  of  the 
nature  of  opsonins. 

The  Bacterium  coli  comtmine,  or  the  colon  bacillus,  is  the  exponent  of  a  grouj)  of 
organisms  inhabiting  the  intestinal  tract,  and  has  been  repeatedly  found  in  fatal 
cases  of  puerperal  infection.  In  one  case  it  was  introduced  by  the  gauze  used  for 
the  packing  of  the  uterus,  the  patient  having  a  diarrheal  evacuation  at  the  time,  un- 
observed by  the  operator.  Gebhard  demonstrated  the  Bacterium  coli  in  a  case  of 
tympania  uteri  which  I  liad  the  privilege  of  observing,  and  Widal,  Bar,  Durante, 
and  von  Franque  have  proved  it  causative  of  puerperal  infections.  Bar  called  at- 
tention to  the  "  colibacillose  gravidique,"  which  manifests  itself  as  appendicitis, 
cholecystitis,  or  uteropyelonephritis.  It  may  cause  general  septicemia,  with  or 
without  metastases,  endocarditis  (Rendu),  meningitis,  otitis,  peritonitis  (but  the 
local  symptoms  are  minimal),  and  phlegmasia  all)a  dolens  (Jeannin).  Usually  the 
infection  is  local,  causing  decomposition  and  suppuration,  vnth.  fetid  lochia  and 
toxinemia.  It  is  often  associated  with  the  streptococcus,  and  the  symbiosis  exalts 
the  virulence  of  the  latter  decidedly  (Bar  and  Tissier). 

The  gonococcus  was  proved  b}'  Kronig,  in  1894,  to  be  responsible  for  many  cases 
of  puerperal  infection.  It  acts  in  two  ways — first,  by  preparing  the  tissues  for  the 
invasion  of  other  organisms,  and  by  symbiosis  exalting  their  virulence,  as  well  as  its 
owTi,  or  it  takes  a  leading  role  itself.  In  a  fatal  puerperal  infection  I  demonstrated 
the  gonococcus  and  the  streptococcus  in  the  peritoneal  exudate.     Halle  and  Rendu, 


830  PATHOLOGY  OF  THE  PUERPERIUM 

Harris  and  Dabney,  have  shown  that  it  can  cause  general  septicemia  with  endocar- 
ditis. ]\Ietastases  may  occur  in  the  joints,  resembhng  those  of  pyococcal  and  strep- 
tococcal infections,  and  in  the  ej-e,  brain,  skin,  bones,  pleurae,  etc.,  but  usually  the 
processes  are  local,  that  is,  acute  urethritis,  endometritis,  salpingitis,  pelveoperi- 
tonitis,  parametritis,  and  ovarian  abscess.  A  latent,  apparently  cured  gonorrhea, 
may,  as  the  result  of  the  traumatism  of  labor  and  the  favorable  cultural  conditions 
of  the  puerperium,  become  acute  and  progredient.  The  gonococcus  produces  no 
exotoxin,  but  contains  endotoxin,  which  is  leukotactic,  yet  the  bacteria  seem  to 
harm  the  leukocytes  but  little.  Infections  with  the  gonococcus  develop  pus  and 
purulent  exudates,  the  general  toxinemia  being  mild  and  the  course  of  the  disease 
usually  favorable,  though  protracted.  Owing  to  the  slow  growth  of  the  organism, 
the  morbid  manifestations  usually  appear  late  in  the  puerperium. 

Many  other  well-knowm  bacteria  have  been  found  as  the  agent  of  more  or  less 
severe  puerperal  infections.  The  Bacillus  pj^ocyaneus,  a  dangerous  organism  for 
children,  rarely  causes  trouble  with  the  mother,  but  when  it  does,  the  reaction  is 
usually  severe,  with  high  fever,  much  prostration,  hemorrhagic  diathesis  (pyo- 
cyaneus  hematoxin),  and  splenic  tumor.  Symbiosis  exalts  the  mutual  virulency. 
In  one  case  of  severe  puerperal  infection  I  found  the  pneumococcus.  It  is  impossible 
clinically  to  distinguish  this  infection  from  those  due  to  other  pus  cocci. 

Bacillus  Typhosus. — In  1898  I  found,  in  the  uterine  lochia  of  a  puerpera  who 
was  ill,  apparently  with  typhoid,  a  culture  of  the  Bacillus  typhosus.  The  Griin- 
baum-Widal  reaction  was  very  marked  in  her  blood.  An  internist,  on  the  general 
S3^mptoms,  would  not  make  a  positive  diagnosis  of  ew^ero-typhoid,  while  the  local 
findings — large,  tender  uterus — pointed  to  an  infection.  The  disease  terminated  by 
lysis,  and  I  believe  this  case  is  similar  to  one  observed  by  Williams  in  the  same  year. 

The  hacillus  of  tetanus  has  repeatedly  been  demonstrated  in  puerperal  tetanus 
(vide  infra),  and  the  Klebs-Loffier  bacillus  of  diphtheria  has  been  found  in  true 
diphtheric  exudates  on  the  puerperal  wounds.  Over  40  cases  of  true  diphtheric 
infection  in  the  puerperium  arc  on  record  (Bourret).  The  streptococcus  and  the 
staphylococcus,  especially  in  association  with  bacilli  of  the  colon  group,  may  pro- 
duce grayish,  greenish,  or  yellowish  pellicles  on  the  vulva  and  vagina,  but  these 
are  not  so  thick  as  those  due  to  true  diphtheria,  and  they  are  more  adherent  to 
their  base.     Bacteriologically,  they  are  easily  differentiated. 

Bacteria  of  decomposition  and  putrefaction,  of  which  there  is  an  immense  host, 
may,  if  given  proper  conditions, — large  amount  of  dead  material  to  feed  on, — pro- 
duce serious,  even  fatal,  toxinemias.  They  produce  toxins  (sepsin),  and  these,  with 
the  by-products  of  their  action  on  albumin  (ptomains,  leukomains,  etc.),  being 
absorbed,  cause  chills,  fever,  vomiting,  stinking  diarrhea,  prostration,  delirium,  etc. 
Duncan  gave  the  name  "sapremia"  to  this  condition,  and  if  thus  restricted,  it  is  a 
term  which  ought  to  be  retained.  Many  authors  use  the  term  as  synonymous  with 
toxinemia  from  all  local  causes.  These  putrefactive  bacteria  are  legion,  anaerobic 
and  aerophile.  Von  Herff  says  that  there  are  nine  forms  of  streptococci  among  the 
aerobic  saprophytes,  together  with  the  Bacillus  coli,  the  Bacillus  aerogenes  cap- 
sulatus,  the  Micrococcus  foetidus.  Staphylococcus  parvulus.  Bacillus  radiiformis, 
Bacillus  nebulosus,  Bacillus  racemosus  (habitual  in  gangrenous  processes),  Bacillus 
caducus,  and  others.  As  a  rule,  these  bacteria  possess  no  invasive  power,  but  some, 
the  Bacillus  coli  and  the  Bacillus  aerogem^s  capsulatus,  the  Streptococcus  putridus, 
may  break  through  the  leukocyte  wall  into  the  lymphatics  and  the  blood.  If  there 
is  much  dead  or  deeply  injured  tissue  about,  these  bacteria  maj'  produce  putrid 
gangrene,  as  in  putrid  endometritis,  and  the  absorbed  toxins  may  be  fatal.  Some- 
times living  tissue  will  succumb  to  the  gangrene-producing  bacteria  and  slough  off 
— metritis  desiccans.  It  is  almost  invaral)le  that  the  streptococcus  and  staphy- 
lococcus— indeed,  any  germ  which  takes  the  leading  role  in  a  given  infection — 
will  have,  in  symbiosis,  one  or  many  of  the  putrefactive  bacteria. 


PUERPERAL    INFECTION  831 

Gas-forming  organisms  are  often  found  in  cases  of  fetid  and  frothy  lochia. 
Dangerous  gas  builders  are  the  Bacterium  coli,  the  Bacillus  aerogenes  capsulatus, 
Bacillus  ocdematis  malignus,  and  the  pseudobacillus  of  malignant  edema.  Of  these, 
the  best  knowTi,  througli  the  labors  of  Welch  and  Williams,  is  the  Bacillus  aerogenes 
capsulatus,  which  is  perhaps  identical  with  the  "vibrion  septique"  of  Pasteur  and 
Doleris.  If  it  invades  the  tissues,  these  become  emphysematous  and  gangrenous; 
if  the  blood,  the  vessels  are  full  of  frothy  blood,  and  the  liver  and  the  spleen  become 
spongy  with  gas.  The  body  swells  up  ^\dth  general  emphysema,  and  there  are 
hemorrhages  and  icterus.  Some  cases  of  so-called  air  embolism  are  really  infections 
of  this  sort.  It  is  rare  to  find  this  organism  alone — usually'  the  pyocyaneus,  the 
proteus,  the  Micrococcus  foetidus,  other  gas-forming  bacilli,  and  especially  the 
Streptococcus  pyogenes,  are  found  in  association.  The  symbiosis  makes  the  germs 
mutually  highly  virulent  and  the  clinical  pictures  intensely  complicated.  If  these 
gas-builders  once  get  beyond  the  confines  of  the  surface  of  the  genital  tract,  they 
usually  evince  terribly  invasive  qualities,  leukoc>i:osis  is  scant,  and  toxinemia  rapid 
and  prostrating.  The  heart  is  quickly  depressed,  hemolysis  occurs,  wdth  jaundice 
and  bleeding  into  vital  organs,  the  serous  surfaces,  and  the  skin. 

Finalh',  in  many  cases  of  puerperal  fever  bacteria  have  been  found  which  cannot 
be  placed  in  our  present  nosolog}',  and  many  occur  which  carniot  be  groA\'n  on  our 
kno^^^l  media. 

Classification  of  the  Forms  of  Puerperal  Infection. — Puerperal  fever  is  a  protean 
disease.  As  may  be  seen  from  the  above,  many  bacteria,  single  and  in  combination, 
may  be  operative,  and  these  ma}-  produce  local  and  general  infections,  both  mild 
and  severe.  Women  react  chfferently  to  these  various  agents — some  possess  im- 
munity, other  a  weakness  against  particular  bacteria.  Some  possess  idiosjnicracies 
for  the  toxins  produced  by  certain  bacteria.  Diseases  of  the  vital  organs  alter  the 
general  reactions  of  the  system  against  invasion,  and  there  are  many  other  conditions 
which  make  the  clinical  pictures  exceedingly  complex,  so  that  a  perfect  anatomic  and 
pathologic  diagnosis  may  rarely  be  made.  For  the  same  reasons  no  classification  of 
them  so  far  offered  is  entirely  satisfactory.  We  may  now  appreciate  the  achieve- 
ment of  Semmelweis,  since  he  saw,  through  the  maze  of  apparently  divergent 
pathologic  processes,  that  they  all  were  due  to  one  underlying  cause — wound  infec- 
tion and  resorption. 

A  classification  founded  on  the  bacteriology,  a  botanic  or  biologic  classification, 
would  be  the  most  scientific,  but,  clinically,  this  is  impractical  because — (1)  Several 
(from  1  to  15)  different  organisms  may  combine  in  producing  the  sjTnptoms;  (2) 
one  organism  can  produce  several  different  forms  of  puerperal  disease  and  differing 
degrees  of  severity;  (3)  the  organism  which  may  be  isolated  from  the  lochia  or  the 
blood,  though  it  often  is,  may  not  be,  the  cause  of  the  morbid  process;  (4)  it  may 
not  be  possible  to  identify  the  germ  which  is  causing  the  worst  sjTnptoms,  or  even 
to  discover  it  at  all. 

Another  classification  is  that  based  on  anatomic  pathologic  findings,  and  which 
divides  the  cases  strictly  according  to  the  parts  involved.  Thus  there  are  vulvitis, 
vaginitis,  endometritis,  parametritis,  perimetritis,  metrophlebitis,  etc.  Clinicalh^ 
this  is  better,  but  not  all  the  forms  of  puerperal  fever  are  localized  to  the  sites  at 
which  the  infection  enters — a  general  sepsis  may  occur  from  a  frenulmn  tear,  and 
any  of  the  germs  mentioned  may  gain  entrance  at  any  place  in  the  genitals  and  pro- 
duce various  and  complicated  sjanptom-complexes,  and,  further,  the  simple  knowl- 
edge of  the  site  of  the  disease  is  not  a  sufficient  guide  to  a  rational  treatment.  To 
say,  for  example,  that  a  woman  has  endometritis  is  by  no  means  enough. 

Crede  divided  the  cases  into  local  and  general  infections,  a  plan  which  01s- 
hausen  and  Bumm,  to  a  certain  extent,  have  followed.  Bumm  first  describes  the 
cases  of  "wound  intoxication,"  or  toxinemia,  which  is  similar  to  the  sapremia  pre- 
viously defined,  and  then  mentions  "wound  infection,"  which  he  divides  into — (1) 


832  PATHOLOGY    OF   THE    PUERPERIUM 

The  local  processes  in  the  pcrincuiu.  the  cervix,  and  the  endometrium;  (2)  the 
spreading  of  the  infection  beyond  the  wound— (o)  tlirough  the  l)lood-vessels,  caus- 
ing septicemia.  thronibophlei)itis,  pyemia;  {h)  through  the  lymph-vessels,  causing 
perimetritis,  parametritis,  metritis  desiccans,  etc. 

The  division  of  the  cases  into  three  forms — sapremia,  septicemia,  and  pyemia — 
is  an  old  one.  and  inaiijiropriate.  Sapremia  has  already  l)een  defined.  It  had  better 
be  replaced  by  the  term  toxinemia.  or  "septic  intoxication."  Septicemia  or  sepsis 
means  the  absorption  into  the  blood  of  living  ferments— bacteria,  which,  multiply- 
ing there  and  in  the  fine  capillaries,  produce  intense  morbid  changes,  either  by  the 
toxins  or  by  capillary  embolism  and  thrombosis.  A  better  term  is  bacteremia, 
septicemia  being  etymologically  incorrect.  Pyemia  literally  means  pus  in  the  blood, 
and  in  some  cases  it  may  l)e  appr()i)riate,  and  if  it  is  understood  to  apply  only  to 
those  cases  where  suppurating  emboli  break  loose  from  an  infected  thrombus  in  a 
vein,  producing  distant  purulent  metastases,  it  may  be  retained.  It  w^ere  better, 
however,  to  replace  it  with  the  term  metastatic  bacteremia,  because  this  describes 
those  cases  where  the  bacteria  themselves  are  transported  from  the  infected  throm- 
bus. These  three  clinical  forms  almost  never  exist  alone,  but  are  combined.  It 
camiot  be  doubted  that  in  all  local  infectious  processes  many  bacteria  get  into  and 
are  killed  in  the  blood-stream.  The  culture  of  the  germs  from  the  blood,  therefore, 
is  not  positive  evidence  of  progressive  bacteremia.  In  all  bacteremias  there  is  also 
toxinemia,  from  toxins  both  developed  in  the  blood  and  al^sorbed  from  the  site  of 
entrance  of  the  germ — the  wound  infection.  As  was  sho^\ii  above,  the  streptococ- 
cus, the  pyococcus,  the  colon  bacillus,  the  capsulated  gas  bacillus,  and  many  others 
may  play  the  role  of  a  saprophyte,  or,  as  the  most  invasive  infectious  agent,  causing 
a  mild  toxinemia,  a  deadly  bacteremia,  or  a  metastatic  bacteremia.  It  is  evident 
now  that  a  generally  applicable  single  classification  is  impossible,  and  for  the  pur- 
poses of  nosology  in  practice  it  will  be  necessary  to  state — (1)  The  site  of  the  en- 
trance of  the  infection  and  its  course;  (2)  the  extent  of  the  infection,  whether  mainly 
local  or  already  generalized;  (3)  the  kind  and  degree  of  virulence  of  the  germ  w^iich 
is  causative.  It  may  not  always  be  possible  to  get  all  this  information.  Our  diag- 
noses will  read  like  the  following  examples:  Toxinemia  due  to  vulvitis — Staphjlo- 
coccus  aureus;  toxinemia  due  to  placental  fragments  and  saprophytic  organisms; 
toxinemia — and  perhaps  slight  bacteremia — from  parametritis — streptococcus; 
bacteremia  from  endometritis — streptococcus,  virulent;  metastatic  bacteremia 
from  metrophlebitis — Staphylococcus  aureus,  mild;    and  so  on.

CHAPTER  LXIV 
CLINICAL  TYPES  OF  PUERPERAL  INFECTION 

EvEX  though  it  is  usually  impossible  clearly  to  distinguish  jietween  a  retention 
toxinemia  and  an  infection  or  bacteremia,  and  even  though  in  practice  the  various 
forms  of  puerperal  infection  to  be  mentioned  may  merge  into  each  other,  still  they 
often  present  clinical  pictures  which  are  fairly  characteristic  and  t^Tiical,  and  suffi- 
ciently sharp  for  diagnosis,  prognosis,  and  treatment.  The  following  are  the  forms 
of  puerperal  infection  most  commonly-  met,  being  placed  about  in  the  order  of  their 
frequency:  \iilvitis  and  colpitis;  endometritis,  mild  and  malignant;  retention  in- 
toxication (the  sapremia  of  Duncan,  or  toxinemia,  from  material  pent  up  in  the 
genitalia);  parametritis;  peritonitis,  pelvic  or  general;  true  bacteremia  or  septi- 
cemia; metastatic  bacteremia  or  septicopyemia;  phlegmasia  alba  dolens;  endo- 
carditis;   tetanus  genitalise;    diphtheria  genitaliae. 

Vulvitis. — Causes  are  traumatism  during  labor  plus  infection.  Previous  dis- 
ease predisposes — for  example,  bartholinitis,  abscess,  fistulas,  etc.  As  a  rule,  after 
operative  deliveries  there  are  more  or  less  contusion  of  the  parts  and  many  little 
wounds  and  abrasions.  If  a  perineorrhaphy  has  been  done,  the  possibility  of  wound 
infection  is  greater.  The  alkaline  blood  and  serum  permit  the  saprophj-tic  strepto- 
cocci and  other  bacteria  to  regain  some  of  their  virulence,  and  it  is  not  unusual  to 
find  these  wounds  covered  with  grayish  or  greenish  exudates,  and  even  superficial 
ulceration  may  occur.  These  are  called  '"puerperal  ulcers,"  and  are  often  accom- 
panied b}'  pronounced  swelling  of  the  whole  vulva.  In  from  six  to  eight  days  the 
swelling  subsides,  the  superficial  sloughs  are  cast  off,  pink  granulations  pushing  up 
to  the  surface,  and  epithelization  rapidly  takes  place,  scar  formation  being  slight. 
If  the  perineorrhaphy  wound  becomes  infected,  the  parts  are  swollen,  with  a  brawny 
exudate;  the  edges  of  the  wound  are  red,  their  line  of  apposition  not  united,  but 
separated  by  pus  and  sloughing  tissue,  serum  and  pus  oozing  out  of  the  stitch-holes. 

Symptoms. — If  the  drainage  is  free,  there  are  no  marked  sj-mptoms.  The 
patient  complains  of  burning  on  urination,  more  or  less  inability  to  urinate,  pain 
and  discomfort  from  the  swelling,  with  a  sense  of  local  heat.  The  temperature  is 
seldom  raised  above  101°  F.,  the  pulse  above  100.  If  suturing  prevents  the  exit  of 
the  infected  exudations,  or  if  the  infective  agent  was  an  alien  streptococcus,  a  sharp 
chill  and  fever,  even  of  104°  F.,  may  usher  in  the  disease;  the  pulse  may  go 
above  120,  and  this  may  be  the  starting-point  of  a  general  bacteremia. 

Vaginitis. — The  causes  arc  the  same — too  much  traumatism  during  labor  plus 
infection.  Too  prolonged  labor,  too  frequent  examinations,  the  use  of  very  hot 
douches  or  of  too  caustic  antiseptics,  prolonged  application  of  the  colpeurynter,  of 
gauze  packing,  bruising  from  brutal  operating,  cutting  by  the  forceps,  by  spiculae  of 
bone  in  craniotomy,  the  retention  in  the  vagina  of  blood-clots,  membranes,  gauze 
sponges,  etc. — all  these  favor  infection  by  producing  conditions  which  develop  the 
virulence  of  the  germs  normally  present  in  the  vagina  (for  example,  the  streptococ- 
cus and  the  staphylococcus).  If,  in  addition,  alien  bacteria  are  introduced,  the 
woman  seldom  escapes  a  dangerous  malady,  because  they  find  ideal  conditions  for 
their  growth  in  the  contused  tissues  bathed  in  an  alkaline  ]:)lood-mixture  containing 
nmch  dead  material,  that  is,  the  lochia.  Astonishing  are  the  recuperative  powers  of 
the  vagina  in  the  absence  of  hetero-infection. 
53  833 


834  PATHOLOGY    OF   THE    PUERPERIUM 

If  the  vagina  were  opened  to  view  by  specula  (which  is  contraindicated),theiisual 
signs  of  inflammation  would  come  into  view,  with  many  puerperal  ulcers  discharg- 
ing purulent  secretions.  If  many  injuries  had  been  laid,  the  wounds  will  be  seen, 
their  edges  covered  ^\^th  sloughs,  and  an  infiltration  extencUng  around  the  vagina, 
even  to  the  walls  of  the  pelvis,  and  a  lymphangitis  may  also  be  found.  These 
wounds  heal  by  granulation,  with  the  free  discharge  of  sometimes  foul-smelling  pus, 
and  leave  cicatrices  which  may  extend  to  the  base  of  the  broad  ligaments,  to  the 
periosteum,  or  under  the  base  of  the  bladder,  causing  fixation  and  distortion  of  the 
pelvic  viscera.  Alien  bacteria,  especially  the  streptococcus,  may  cause  pericolpitis, 
peritonitis,  and  even  bacteremia.  The  sj'mptoms  are  severer  than  those  of  vulvitis, 
especialh'  if  the  causative  bacteria  are  invasive  or  produce  much  toxin.  If  drainage 
is  free,  the  general  reaction  is  usually  mild;  if  the  discharges  are  retained  (a  con- 
dition called  lochiocol'pos) ,  severe  toxinemic  manifestations  arise  {vide  infra). 

The  diagnosis  of  vulvitis  is  easily  made  by  inspection  of  the  vulva.  This  is  a 
good  place  to  call  attention  to  the  value  of  the  signs  present  on  the  vulva  indicating 
infection  higher  up.  Early  in  the  disease  the  presence  of  puerperal  ulcers  may  be 
very  significant  of  grave  infections  involving  the  uterus.  The  infectious  lochia 
washing  over  the  "\ailvar  wounds  almost  always  cause  superficial  necrosis.  As  the 
disease  heals  the  local  signs  disappear,  ^'aginitis  is  never  present  without  some  in- 
flammation of  the  vulva. 

Treatment.- — Douches,  internal  examinations  by  the  finger  or  with  specula,  are 
contraindicated.  If  the  retention  of  a  gauze  sponge  is  suspected,  a  rectal  examina- 
tion vnW  disclose  it.  If  there  are  sutures  in  the  perineum,  they  are  to  be  removed 
on  the  first  suspicion  of  an  infection.  To  leave  them  in  the  hope  of  getting  a  union 
in  spite  of  the  infection  is  to  trifle  with  an  unknoviTi  foe,  and  usually  be  defeated 
in  the  end.  If  the  confined  infective  exudates  do  not  cause  paracolpitis,  para- 
metritis, or  even  general  infection,  the  tissues  break  down  into  pus  which  escapes 
into  the  vagina,  and  the  skin  only  uniting,  prolapsus  vaginae  and  descensus  uteri 
follow,  nevertheless.  After  removal  of  the  sutures  and  opening  up  the  recesses  of 
the  wound  widely  the  latter  may  be  flushed  with  tincture  of  iodin,  and  a  thin  strip 
of  gauze  laid  between  its  edges  to  keep  up  drainage.  External  flushings  with  a  weak 
antiseptic  are  frequently  practised,  but  no  vaginal  douches,  since  these  may  carry 
the  infection  higher.  Ergot  and  hydrastis,  15  minims  of  the  fluidextract  of  each, 
are  given  four  times  daily,  the  bowels  are  kept  free,  and  hexamethylentetramin,  5 
grains  four  times  a  day,  exhibited,  if  there  is  the  least  indication  on  the  part  of  the 
bladder.  I  often  use  the  latter  as  a  preventive.  For  the  relief  of  local  pain  and 
discomfort  a  warm  wet  boric  or  lead-water  dressing  may  be  used. 

Endometritis. — Very  few  puerperal  infections  occur  without  involvement  of  the 
endometrium.  Indeed,  the  cervix  and  endometrium  are  the  ports  of  entry  to  the 
parametrium,  the  perimetrium,  the  tubes,  and  the  shortest  way  to  the  blood  itself. 
The  reasons  for  the  frequent  involvement  of  the  endometrium  are:  (1)  The  cervix 
and  the  lower  uterine  segment  are  particularly  exposed  to  the  traumatisms  of  lal^or 
and  of  operative  delivery;  (2)  the  mucous  membrane  is  verj"  delicate  in  structure 
as  compared  with  that  of  the  vagina,  and  it  is  covered  wdth  a  layer  of  dying  decidua, 
favorable  to  the  growth  of  bacteria;  (3)  blood-clots,  membrane,  even  placental 
fragments,  may  be  retained;  (4)  the  infection  may  have  been  present  in  the  endo- 
metrium during  pregnancy  (see  IMicrobic  Endometritis),  or  brought  there  directly 
by  colpeurA-nter,  bougie,  or  decomposed  liquor  amnii;  (5)  shreds  of  membrane 
hanging  dowTi  in  the  vagina  act  as  a  bridge  on  which  the  bacteria  mount  into  the 
uterus;  (6)  the  open  vessels  of  the  placental  site  are  particularly  favorable  to  the 
nidation  of  germs;  (7)  if  the  uterus  is  flabby  and  relaxed,  stasis  of  the  lochia  may 
occur,  a  condition  particularly  favorable  to  bacterial  growth. 

It  must  not  be  supposed  that  the  presence  of  decidua  or  even  a  piece  of  pla- 
centa in  utero  means  that  it  will  cause  an  endometritis.     The  infection  must  also 


CLINICAL   TYPES   OF   PUERPERAL   INFECTION 


835 


be  present.     Pieces  of  placenta  can  remain  in  the  uterus  for  weeks  without  decom- 
posing, until,  after  a  careless  examination,  the  infection  begins. 

The  importance  of  a  well-contracted  uterus  was  recognized  even  in  the  olden 
time.  A  uterus  that  is  relaxed  absorbs  very  actively  toxins  produced  in  its  interior, 
and  again  it  allows  them  to  accumulate  here.  A  well-contracted  uterus  expels  de- 
composing clots,  secretions,  etc.,  and,  in  addition,  has  less  absorptive  power,  since 
both  blood-vessels  and  lymphatics  are  held  closed.  If  the  uterus  becomes  bent  on 
itself  at  the  cervix,  especially  after  the  sixth  day,  when  the  uterus,  being  strongly 
anteverted,  may  catch  behind  the  symphj'sis,  or  if  retroflexed,  untler  the  promon- 
tory, the  lochia  may  be  pent  up,  and  a  condition  analogous  to  lochiocolpos  results.

It  is  more  common  than  this,  and  is  called  lochiometra.  It  usually  causes  a  severe 
chill  and  rise  in  temperature,  which  go  down  just  as  quickly  if  the  cause  is  removed. 
Pathology. — To  avoid  repetition,  the  reader  is  referred  to  p.  208  for  a  description 
of  the  changes  in  the  normal  uterus.  In  endometritis  the  mucous  membrane  is 
swollen,  rough,  covered  with  thickened  decidua  in  a  state  of  necrosis,  and  the  surface 
is  moist,  with  a  mucopurulent,  sometimes  hemorrhagic,  smeary  material.  The 
cervix  is  almost  always  involved  in  the  same  way;  it  is  swollen  and  eroded,  and,  in 
addition,  the  wounds  are  covered  with  puerperal  ulcers.  Involution  becomes 
slower,  and  the  uterus  becomes  edematous  and  relaxed,  giving  the  germs  ready  ac- 
cess to  the  blood.  Bumm  distinguished  two  forms  of  endometritis — first,  that  due 
to  putrid  or  bacillary  infection,  in  which  the  bacteria  were  limited  to  the  surface  and 
to  the  necrotic  material  there  by  a  protecting  bank  of  white  cells  and  granulations, 


836 


PATHOLOGY  OF  THE  PUERPERIUM 


and,  second,  a  coccal  or  septic  infective  form,  where  the  liacteria,  usually  strepto- 
cocci and  pyococci,  invade  the  lymphatics  and  blood-vessels  after  overcominp;  the 
bank  of  leukocytes  and  o;ranulations.     After  examining  many  specimens  I  was  able

to  find  onl}'  one  where  the  bacteria  were  limited  to  the  surface  (Figs.  739  and  740). 
In  the  putrid  endometritis  the  surface  of  the  endometrium  is  covered  mth  a  thick, 
fetid  material,  often  containing  gas-bu})bles,  and  of  a  grayish  or  yellowish-greenish 
color — even  l^lack  from  decomposed  blood.     It  is  impossible  to  wipe  the  surface

smooth,  as  in  the  normal  uterus.  If  the  bacteria  are  more  virulent,  they  cause  ac- 
tual sloughing  of  the  endometrium,  with  many  superficially  ulcerated  areas,  covered 
with  a  diphtheroid  (not  diphtheric)  exudate,  and  the  whole  interior  of  the  uterus 
has  a  putrescent  appearance  and  odor — putrescentia  uteri.     Usuallj'  the  pus  cocci

and  the  bacteria  of  decomposition  are  here  associated.  If  the  gangrene  goes  deeper 
into  the  waU  of  the  uterus,  an  evidence  of  still  greater  virulence  of  the  bacteria 
(streptococci  and  anaerobes),  larger  or  smaller  portions  of  the  lining  of  the  uterus, 
or  even  of  the  muscle  itself,  may  slough  off — thf  metritis  desiccans  of  CJarrigues.

Schottmiiller  showed  that  the  majority  of  cases  of  endometritis  putrida  were  due 
to  an  obligate  anaerobic  streptococcus.  He  demonstrated  this  coccus  in  parame- 
tritis and  perimetritis,  in  pyosalpinx,  and  in  the  blood  of  cases  which  formerly 
were  called  toxinemia. 

Infections  due  to  Streptococcus  pyogenes  and  the  pyococci  alone  do  not  give

rise  to  fetor,  and  the  surface  of  the  uterus  is  usuahy  smooth  and  not  deeply  necrotic. 
In  rare  instances  the  infection  is  Hniited  to  the  placental  site,  being  usuall}^  mild,  due 
to  a  pyococcus  of  attenuated  virulence,  and  producing  little  local  inflammation,  ])ut 
often  protracted  forms  of  metastatic  bacteremia.     (See  Pyemia.) 

As  a  general  rule,  the  bank  of  granulations  suffices  to  limit  the  infection  to  the 
uterus,  unless  nature's  beneficent  processes  are  disturl^ed  by  the  meddling  accou- 
cheur; but  sometimes  the  bacteria,  especially  the  streptococcus,  pass  on  into  the 
lymphatics,  causing  parametritis  and  perimetritis,  even  general  peritonitis,  or 
bacteremia,  or,  through  the  veins  via  the  thrombi,  causing  metastatic  bacteremia 
of  an  acute  type.     To  these  forms  reference  again  will  be  made. 

Symptoms. — For  the  first  two  or  three  daj's  the  puerpera  is  fairl}-  well,  but  an

acute  observer  will  find  that  there  arc  vague  indications  of  brewing  trouble.  Slight 
malaise,  unrest  at  night,  pain  in  the  uterus,  prolonged  after-pains,  or  their  recur- 
rence after  having  subsided,  will  attract  the  accoucheur's  attention.  On  the  third, 
fourth,  or  fifth  day  there  is  a  slight  chill  or  chilly  s(>nsation,  with  rise  of  temperature, 
and  all  the  usual  febrile  symptoms — feeling  of  heat,  anorexia,  insomnia  (except  in 
the  very  mild  cases),  headache.  Objectively,  the  accoucheur  will  find  the  pulse  100 
to  140,  and  the  temperature  101°  to  104°  F.,  depending  on  the  severity  of  the  infec- 
tion. The  abdomen  is  perhaps  a  trifle  distended,  but  there  is  no  tenderness;  the 
uterus  is  usually  larger  than  it  should  be  on  the  day  in  question  (Fig.  744),  and  softer 
than  normal — that  is,  in  a  state  of  retarded  involution.  Rarely  is  tenderness  absent, 
and  the  sides  are  often  sensitive  to  even  light  palpation.  The  lochia  at  the  very 
first  are  unaltered,  but  within  forty-eight  hours  have  lost  their  characteristic  quali- 


CLINICAL   TYPES    OF   PUERPERAL    INFECTION  839 

ties  and  become  serous,  flesh-water  colored,  or  seropurulent.  Unless  saprophytes 
have  developed  in  large  numbers,  the  lochia  are  not  foul,  but  they  have  an  in- 
sipid or  purulent  odor.  The  lochia  have  caustic  and  infective  qualities,  and  soon 
the  wounds  about  the  vulva  are  covered  with  a  diphtheroid  exudate,  forming  the 
puerperal  ulcers  already  mentioned. 

Unless  the  infection  is  verj'  virulent,  the  symptoms  and  objective  signs  are  no 
more  threatening  than  described;  the  temperature,  after  pursuing  a  remittent 
(1°  to  2°  F.)  course  for  four  or  five  days  (Fig.  745),  subsides  by  lysis,  the  pulse  slows, 
and  in  six  to  ten  days  recovery  is  established.  If  the  infecting  bacteria  are  strong 
enough  to  overcome  the  protecting  wall  of  leukocj'tes,  the  blood  is  involved  and  the 
general  symptoms  are  marked,  the  case  ha\ang  become  a  bacteremia  (see  below). 

Diagnosis. — Endometritis  has  no  characteristic  sj-mptoms.  With  the  usual 
manifestations  of  infection  one  finds  a  large,  sensitive  uterus,  e\adences  of  slight 
peritoneal  irritation,  and  altered  lochia.  The  vulvar  wounds  have  an  unhealthy 
aspect,  except  when  the  endometritis  is  due  to  non-virulent  saproph}i;es,  in  which 
case  these  wounds  may  heal  under  healthy  granulations.  If  a  specular  examination 
is  made,  the  condition  of  the  cervix  will  be  a  criterion  of  the  condition  of  the  endo- 
metrium. The  lochia  in  the  putrid  infections  are  profuse,  thick,  and  foul,  while  in 
the  streptococcic  kinds  they  are  diminished,  thin,  sanious,  with  an  acrid  odor. 
The  absence  of  signs  of  peritonitis  and  of  tumor  eliminates  localization  outside  the 
uterus.     Prognosis  and  treatment  will  be  discussed  later. 

Sapremia,  Retention  Fever,  Toxinemia. — Clinically,  a  not  small  group  of  cases 
exists  with  fever  and  often  very  threatening  s^^nptoms,  due  to  the  absorption  of 
toxins  from  decomposing  material  in  the  genital  tract.  Lochiocolpos  and  lochio- 
metra  have  already  been  referred  to.  If  the  toxins  were  always  the  result  of  the 
action  of  saproph^'tic  bacteria,  the  organisms  of  putrefaction,  the  term  sapremia, 
proposed  by  Duncan,  Avould  apply.  But  the  streptococcus  and  other  cocci  and 
bacteria  may  grow  in  the  dead  tissue  and  produce  toxins,  which  are  absorbed,  and, 
further,  the  author  would  rather  agree  -u-ith  Schottmliller,  Latzko,  and  Zangemeis- 
ter,  as  opposed  to  Doderlein,  Bumm,  and  others,  that  in  all  these  cases  many  bacteria 
get  into  and  are  killed  in  the  blood.  The  distinction,  therefore,  between  toxinemia 
and  bacteremia  is  mainly  one  of  degree,  and  the  term  sapremia  must  be  limited  to 
those  infections  where  only  putrefactive  organisms  are  present.  We  use  the  terms 
septicemia  and  sepsis  in  a  very  loose  way  to  mean  a  bacteremia  hx  the  pus-cocci, 
when  the  Greek  original  means  putridity.  We  might  also  thus  use  the  term 
sapremia,  but  it  would  be  better  to  discard  all  three,  which,  however,  at  present  is 
impractical. 

When  a  puerpera  develops  fever,  which  by  exclusion  is  found  to  come  from  the 
genitals,  the  first  question  that  arises  is,  Is  there  anj-thing  in  the  uterus?  If  there 
is  a  piece  of  placenta,  a  clot,  or  a  mass  of  membranes  in  the  uterus,  the  same  may  not 
become  infected  if  the  uterus  is  firmly  contracted  and  if  no  alien  bacteria  are  carried 
in  from  the  outside.  Should  it  become  infected,  the  symptoms  are  those  of  endo- 
metritis, and  there  is  always  more  or  less  reaction  in  the  endometrium. 

Another  danger  of  these  infected,  necrosing  bodies  lies  in  their  providing  a 
favorable  nidus  for  the  virulent  streptococcus,  in  developing  the  virulence  of  weak- 
ened cocci,  or  native  bacteria,  or  in  altering  the  subjacent  mucosa,  so  that  it  offers 
less  resi.stance  to  the  microorganisms  normally  present  in  the  vagina,  cervix,  and 
uterus.  Bacteremia  has  often  followed,  but  in  most  cases  the  disease  remains  local, 
and  there  is  no  marked  invasion  of  the  hTiiph-  and  blood-streams. 

Symptoms. — It  is  impossible  to  distinguish  this  condition  from  an  endometritis, 
since  the  s^miptoms  are  nearly  identical.  Lochiometra  and  lochiocolpos  are  char- 
acterized by  absence  of  the  lochia.  If  a  piece  of  membrane  or  placenta  has  been 
retained,  the  after-pains  often  continue  until  it  is  expelled,  after  which  also  the  fever 
and  rapid  pulse  subside.     Profuse  and  very  bloody  lochia  are  the  rule  if  portions  of 


840 


PATHOLOGY    OF   THE    PUERPERIUM 


the  placenta  are  retained,  and  repeated  hemorrhages  or  the  passage  of  clots  are  al- 
most pathognomonic.  The  uterus  is  large  and  soft  in  such  cases.  As  an  aid  to  the 
diagnosis  the  history  of  the  labor  is  useful,  since  the  placenta  ma>'  have  shoA\Ti  de- 
fects, or  the  prolonged  oozing  postpartum  may  have  led  the  accoucheur  to  believe 
that  there  was  a  clot  in  the  uterus.  Since  uterovaginal  examinations  are  not  per- 
mitted, the  state  of  the  uterine  cavity  can  only  be  guessed  at.  A  rectal  exploration 
might  reveal  a  mass  in  the  vagina,  or  a  retroflexed  or  antefiexed  uterus,  causing 
lochiostasis,  and  the  protrusion  from  the  vulva  of  a  shred  of  membrane  or  a  bit  of 
placenta  might  indicate  that  there  may  be  more  higher  up.  Treatment  will  he 
considered  later.

pelvic  connective  tissue,  and  Velpeau  associated  them  with  tlie  genital  organs, 
which  Doherty  proved  in  1843.  Virchow  applied  the  term  parametritis  to  these 
pelvic  phlegmons,  but  pelvic  ceUulitis  is  a  better  one,  because  the  disease  is  very 
seldom  limited  to  the  neighborhood  of  the  uterus,  but  may  involve  the  connective 
tissue  from  the  vulva  to  the  kidney,  and,  further,  it  does  not  alwaj^s  begin  around 
the  uterus.  Through  the  researches  of  ]\Iatthews  Duncan,  W.  A.  Freund,  and  A. 
von  Rosthorn,  our  knowledge  of  pelvic  cellulitis  has  been  placed  on  firm  foundation. 
Causation. — As  in  the  other  puerperal  infections,  pelvic  cellulitis  is  caused  l)y 
bacteria,  and  these  gain  entrance  to  the  coimective  tissue  in  various  ways  (Fig. 
747).  In  most  cases  the  atrium  of  infection  is  a  wound  of  the  cervix  or  lower  uterine 
segment,  but  the  injury  may  have  been  in  the  vagina  or  even  the  perineum.  Bac- 
teria may  break  through  the  granulation  bank  in  the  endometrium,  antl,  passing

through  the  uterine  wall  l)y  way  of  either  the  lymphatics  or  the  blood-vessels,  reach 
the  parametrium,  and,  finally,  they  may  wander  into  the  subjacent  tissues  from  the 
peritoneum  or  the  tubes,  which  may  be  infected. 

Nearly  always  it  is  the  Streptococcus  pyogenes  which  is  the  causative  organism, 
but  the  staphylococcus  has  Ijeen  found, 
also  the  colon  bacillus,  though  usually 
as  a  concomitant  infection,  and  even 
the  gonococcus  (jMenge  and  Doderlein). 
]\Iany  factors  favor  infection  of  the 
connective  tissue  in  the  pelvis  after 
labor.  Besides  the  general  softening, 
the  edematous  imbibition  of  the  tissues, 
the  enlargement  of  the  connective-tis- 
sue spaces,  and  the  increased  vascu- 
larity due  to  pregnancy,  there  is  the 
direct  bruising  of  the  parts,  with  the 
bloody  and  serofibrinous  extravasa- 
tions. To  these  must  be  added  the 
immediate  introduction  of  alien  and 
native  bacteria  through  lacerations  in- 
to the  opened  spaces,  by  means  of  the 
hands,  instruments,  gauze,  etc. 

Pathology. — Cellulitis  in  the  pelvis 
differs  very  little  from  cellulitis  under  the  skin  or  elsewhere.     The  bacteria,  by  their 
presence  and  the  toxins  they  produce,  irritate  the  tissues,  a  protective  serum  is 
thrown  out  (inflammatory  edemaj,  leukocytes  hurry  to  the  scene,  the  binding  cells 

proliferate  and  form  fibrin,  all 

of  which  compose  an  exudate 

♦^    i-,       .A  -^        in  the  infected  area.     The  bac- 

teria  pass  along  the  lines  of 
least  resistance,  and  these  are 
the  natural  planes  of  cleavage 
of  the  pelvic  connective  tissue, 
and  are  limited  by  firm  laj^ers 
of  fascia  and  by  the  organs  in 
the  pelvis.  The  inflammatory 
exudates,  therefore,  following 
the  infection  vdW  extend  in  cer- 
tain tlirections,  passing  along 
the  planes  of  fascia,  and  sur- 
rouncUng  and  embedcUng  the 
hollow  pelvic  organs.  Since 
the  inflammatory  reaction  is 
sometimes  excessive,  the 
amount  of  serum  and  fibrin 
and  cellular  infiltration  may 
overfill  the  tissue-spaces,  and 
the  exudate  itself  may  wander. 
On  the  other  hand,  the  bacteria 
may  select  an  unanatomic 
course,  for  example,  through  a  fascia  or  muscle,  and  then  the  inflammatory 
exudate  will  be  found  where  it  was  not  expected.  Von  Rosthorn's  classification 
of  pelvic  exudates  is  the  most  practical:  (1)  Lateral  horizontal  exudates  located 
in  the  bases  of  the  broad  ligaments,  with  a  tendency  to  spread  to  the  side  walls  of

the  pch'is  and  around  the  cervix;  these  usually  come  from  cer\-ix  tears;  (2)  high 
intraligamentous  infiltrations  beginning  near  the  cornua  uteri,  forming  tumors, 
rounded  above,  with  a  tendency  to  unfold  the  broad  ligaments  and  climl)  up  into  the 
iliac  fossa);  these  usually  come  from  endometritis;  (3)  exudates  in  the  n^trocervical 
connective  tissue,  with  a  tendencj^  to  spread  either  posteriorly  along  the  uterosacral 
ligaments  or  sink  in  the  rectovaginal  septum;  (4)  exudates  in  the  precervical  tissues, 
and  spreading  toward  the  sides,  around  the  ureters;  (5)  exudates  anterior  to  the 
bladder,  behind  the  pubis,  with  the  tendency  to  rise  behind  the  recti  muscles,  even 
to  the  navel — ''plastron  abdominal"  of  the  French.  Several  of  these  forms  may 
be  combined.  The  most  common  is  the  lateral,  extending  from  the  side  of  the  uterus 
to  the  bony  pelvic  wall,  then  anteriorly  around  the  ureter,  raising  the  peritoneum 
up  and  appearing  above  Poupart's  ligament.  Rarer  distributions  are :  Posteriori}^, 
to  the  sacrum  and  up  to  the  kidney,  or  even  to  the  diaphragm  and  through  it; 
laterally,  out  through  the  sciatic  foramen  into  the  thigh;  or  inside  the  infundibulo- 
pelvic  ligament  along  the  psoas,  involving  the  tissues  around  the  luml^ar  plexus  of 
nerves. 

The  exudation  varies  in  extent  and  consistence,  depending  on  the  virulence

of  the  germ  and  the  resistance  of  the  patient.  In  mild  cases  there  is  only  a  simple 
inflammatory  edema,  and  in  the  severest  cases  also  the  process  is  limited  to  a 
serous  and  poorly  cellular  infiltration,  the  bacteria  passing  quickly  through  the 
lymphatics  into  the  blood.  Most  often  there  is  adequate  reaction,  with  the  forma- 
tion of  large  exudates.  If  a  section  is  made  through  the  inflamed  tissues  at  the 
side  of  the  uterus,  the  lymph-vessels  will  be  found  thickened,  tortuous,  and  beaded, 
and  a  yellowish  or  whitish  pus  exudes  from  numerous  fine  openings.  Around  them 
the  exudate  lies,  and  it  gives  the  surface  a  glistening,  glassy,  moist  appearance. 
Later,  white-cell  infiltration  and  fil)rin  exudation  solidify  the  tissue  and  make  it 
opaque.  The  veins  are  oft(^n  thrombotic,  and  if  they  were  primarily  infected,  or 
even  if  they  become  so  secondarily,  the  thrombi  may  undergo  puriform  degenera- 
tion, the  debris  breaking  up  and  often  getting  into  the  circulating  blood  as  infected 
emboli.  The  arteries  are  usually  not  affected.  Later,  whc^n  shrinking  of  the  scars 
occurs,  the  arteries  may  be  kinked,  the  same  being  true  of  the  veins,  and  varicosities 
may  develop,  or  chronic  venous  congestion,  with  its  noxious  results.  Impli(!ation 
of  the  ganglia  and  the  nerves  in  the  pelvis  results  in  their  partial  destruction,  but 
more  often  in  neuritis  and  perineuritis,  with  recovery  or  compromise  of  function. 


CLINICAL   TYPES    OF    PUERPERAL    INFECTION  843 

The  peritoneum  of  the  pelvis  alwaj's  takes  part  in  the  inflammation;  the  tubes  and 
ovaries  are  matted  to  the  broad  hgaments  or  the  uterus,  and  the  intestines  are  ad- 
herent to  the  pelvic  masses  of  exudate.  It  may  be  difficult  to  saj'  whether  the  para- 
metritis or  the  perimetritis  is  of  greater  moment. 

Nature  cures  these  cases  in  two  waj's:  Either  the  exudates  are  reabsorlied  or 
they  suppurate.  In  the  latter  instance  the  pus  is  discharged  externally  or  encap- 
sulated, or  complete  resorption  occurs.  If  resolution  takes  place,  the  ex-uded 
fluids  are  absorbed,  phagocytes  attack  the  fibrin  and  detritus  (the  dead  leukocytes 
and  dead  bacteria),  and  digest  them  or  carry  them  off.  The  new-formed  connec- 
tive-tissue cells  make  the  scar  tissue,  and  fibrous  bands,  and  cicatricial  thickenings 
which  mark  the  site  of  the  inflammation.  These  cicatrices  distort  the  pelvic  or- 
gans, as  regards  position,  shape,  and  function.  The  uterus  is  sometimes  found 
drawn  over  to  one  side  of  the  pelvis,  and  moored  here  immovably;  or  it  may  l)e 
drawn  up  toward  the  sacrum  by  the  shortening  of  the  uterosacral  ligaments — 
Schultze's  anteflexion, — or  it  may  be  twisted  on  itself.  Sometimes  the  neck  of  the 
bladder  is  pulled  open  by  the  retracting  scars,  causing  incontinence  or  "irritable 
bladder."  Stricture  of  the  rectum  may  result.  Thickenings  in  the  fornices,  in 
the  uterine  ligaments,  with  displacements  of  the  uterus,  are  very  conmion  in  daily 
practice  and  indicate  the  frecjuency  of  mild  forms  of  pelvic  cellulitis  (Emmett). 

If  the  process  ends  by  suppuration,  necrotic  areas  appear  in  various  parts  of 
the  exudate,  wliich  become  converted  into  pus.  The  whole  exudate  may  become 
one  abscess  or  several,  separated  by  septa.  Thus  the  entire  pelvis  may  be  riddled 
with  aliscesses.  DepencUng  on  the  location  of  the  exudate  and  its  proximity  to  one 
of  the  hollow  organs  of  the  pelvis,  pointing  will  occur,  and  unless  there  is  operative 
interference,  in  the  course  of  from  twenty  to  seventy  days  the  abscess  will  break 
into  the  rectum,  vagina,  bladder,  ureter,  skin,  or  general  peritoneal  cavity.  Then, 
if  there  is  no  other  focus  of  suppuration,  the  cavity  closes  rapidly.  If  there  are 
other  foci,  these  may  undergo  the  same  process,  and  thus  the  patient  may  be  ill 
with  suppurating  cavities  for  months  and  even  j'ears. 

These  latter  cases  and  the  immense  exudates  extending  to  the  navel  or  kidney 
are  very  rare  nowadays-,  but  in  the  preantiseptic  time  they  were  common.  Some- 
times the  abscess  does  not  open,  and  nature  cures  by  encapsulating  the  pus.  The 
wall  of  the  abscess  thickens  and  gets  firm  with  fibrous  tissue;  the  more  fluid  part 
of  the  pus  is  absorbed,  and  such  a  tumor  may  persist  in  the  pelvis  for  years,  grad- 
ually shrinking  in  size.  I  watched  one  such  case  eight  years,  and  the  condition  had 
existed  for  six  j-ears  before.  A  chnically  important  fact  is  that  the  germs  do  not 
always  lose  their  virulence,  but  may,  on  the  occasion  of  traumatism,  exposure,  ill 
health,  etc.,  break  out  with  renewed  hiry  and  establish  a  general  bacteremia  (jMartin 
and  Busse,  loc.  cit.,  p.  119).  Even  in  the  scars  from  exudates  which  supposedly 
had  been  reabsorbed  tiny  pus  cavities  containing  virulent  bacteria  may  later  be 
found,  a  point  of  immense  clinical  and  medicolegal  im]oortance. 

Symptoms. — In  the  mildest  forms,  traces  of  which  are  found  during  a  g3^leco- 
logic  examination  as  a  thickening  in  one  of  the  fornices,  or  a  displaced  uterus,  the 
symptoms  during  the  puerperium  are  hardly  noticeable.  A  slight  rise  of  tempera- 
ture, a  little  local  tenderness,  and  mild  febrile  symptoms,  which  are  usually  referred 
to  something  else  or  to  "7mlk  fever,"  may  not  even  call  the  attention  of  the  accou- 
cheur to  the  pelvis  at  the  time. 

With  the  severer  grades,  however,  there  are  marked  signs  of  disease.  The 
symptoms  usually  begin  on  the  third  or  fourth  day.  If  the  fifth  day  has  passed 
without  symptoms,  according  to  Olshausen,  there  is  little  danger.  Still,  I  have  seen 
parametritis  begin  on  the  eighth  and  ninth  day.  These  cases  are  called  late  fever, 
and  are  sometimes  due  to  too  early  getting  up,  which  starts  up  anew  an  unnoticed 
parametritis,  or  the  movements  tear  open  some  small  wound  in  the  cervix,  or,  after 


844  PATHOLOGY  OF  THE  PUERPERIUM 

some  local  treatment  or  examination,  these  wounds  are  reopened  and  infection 
enters. 

Nearly  always  the  symptoms  of  an  endometritis  precede  those  of  parametritis, 
and  an  acute  observer  may  be  able  to  determine  the  time  when  the  infection  passes 
the  bounds  of  the  uterus  and  strikes  into  the  broad  ligaments.  A  chill  c)r  chilli- 
ness, fever  of  103°  or  104°  F.,  pulse-rate  100  to  110,  and  marked  local  pain  are 
constant,  together  with  the  general  manifestations  of  the  febrile  state — headache, 
anorexia,  restlessness,  sleeplessness,  soreness  of  the  body.  All  movements,  cough- 
ing, sneezing,  etc.,  are  painful.  Xausea  and  vomiting  are  unusual,  but  do  occur, 
and  generally  indicate  that  the  peritoneum  is  involved  to  some  extent.  They  do 
not  persist  as  in  peritonitis.  The  general  impression  the  attendant  gets  is  that  the 
patient  is  not  seriously  ill.  Sometimes  the  parametritis  is  hidden  under  the  sjaiip- 
toms  of  a  general  sepsis.  The  fever  is  at  first  quite  continuous,  but  soon  becomes 
remittent,  and  later,  when  pus  has  formed,  it  may  be  intermittent.  Now,  repeated 
chills  occur,  and  sweats  accompany  the  defervescence.  Unless  the  pus  cavities  are 
freely  evacuated,  the  patient  may  pass  into  a  condition  called  by  the  older  writers 
"hectic,"  and  maj^  die  of  exhaustion,  having  wasted  to  a  skeleton.  Rapid  dis- 
appearance of  the  symptoms  follows  on  proper  drainage  of  the  abscesses. 

If  absorption  of  the  exudate  takes  place,  the  temperature  graduall}'  subsides, 
the  local  symptoms  disappear  for  the  time,  but  later  symptoms  referable  to  some 
pelvic  displacement  make  themselves  apparent,  and  often  the  patient  becomes  an 
invalid  for  life. 

Resolution  may  require  only  ten  days,  while  sometimes  it  may  be  sixty  days 
before  the  patient  can  safely  get  up.  The  severity  of  the  local  process  can  usually 
be  determined  by  the  general  symptoms,  e.  g.,  temperature  and  pulse,  but  not  al- 
Avays,  as  sometimes  a  moderate  amount  of  exudation  causes  severe  symptoms,  while 
again  a  large  exudate  will  exist  with  onh'  mild  manifestations  of  disease. 

Locally  in  the  early  period  will  be  found  the  large,  soft,  tender  uterus  of  infec- 
tion, subinvolution,  and  at  either  side  of  the  uterus,  deep  in  the  flanks,  marked 
tenderness  on  pressure,  but,  relatively  to  peritonitis,  little  rigidity.  It  is  not  best 
to  make  a  vaginal  examination.  "When  I  have  done  so  at  this  time  I  found  the 
whole  pelvis  hot  and  soft,  with  one  spot,  usually  the  lateral  fornix,  very  sensitive, 
and  an  ill-defined  thickening  present  in  this  region.  The  lochia  may  have  the 
appearance  of  the  lochia  from  endometritis.  If  the  infection  entered  at  the  site  of 
a  cervical  tear,  the  puerperal  discharges  vasLy  not  be  much  altered.  Later  the  exu- 
date may  be  palpated  as  a  firm,  sometimes  almost  wood-like,  tumor,  at  the  side  of 
the  uterus  or  filling  the  pelvis  more  or  less,  embedding  the  pelvic  organs  as  one 
might  do  Avith  paraffin.  If  suppuration  occurs  in  the  mass,  the  numerous  tiny 
abscesses  fuse  together  into  a  large  one,  palpable  to  the  finger,  and  pointing  occurs. 
\'aginally,  the  soft  abscess  may  be  felt  bulging  down  one  of  the  fornices,  or  it  may 
better  be  felt  per  rectum.  Abdominally,  the  tumor  causes  a  prominence  above  one 
or  the  other  Poupart's  ligament,  the  skin  becomes  slightly  edematous,  reddens,  and, 
unless  the  accoucheur  anticipates  it,  the  tissues  break  down  over  the  abscess  and 
the  pus  escapes  externally.  Spontaneous  rupture  of  the  pus-sac  into  the  rectum, 
the  bladder,  or  the  vagina  seldom  occurs  before  the  third  week,  and,  through  the 
abdominal  wall,  still  later.  If  resorption  occurs,  the  tumor  hardens  and  shrinks, 
at  first  rapidly,  later  slowly,  recjuiring  three  to  twelve  weeks,  and  rarely  several 
years,  to  disappear. 

Pressure  of  the  exudate  on  the  various  hollow  visc(>ra  in  the  pelvis,  and  com- 
munication of  the  infection  to  them,  are  accompanied  by  symptoms  appropriate  to 
each  organ.  Cystitis,  ureteropyelitis,  even  hydronephrosis  from  ureteral  obstruc- 
tion, with  uremia  and  death,  have  been  noted.  GEdema  bullosum  precedes  the 
opening  of  the  abscess  into  the  bladder.  Proctitis,  with  mucous  and  blood}'  diar- 
rhea, often  precedes  the  discharge  of  the  pus  per  rectum.     Involvement  of  the 


CLINICAL    TYPES    OF    PUERPERAL    INFECTION 


845 


nerves  in  the  pelvis  causes  neuralgias,  and  even  paralyses  of  the  muscles  in  the  legs. 
If  the  infection  takes  the  path  along  the  blood-vessels  to  the  thigh,  one  of  the  forms 
of  piilegmasia  alba  dolens  ma}'  result  {q.  v.). 

Diagnosis. — At  first  it  may  not  be  easy  to  differentiate  this  infiammation  from 
others  in  the  pelvis,  though  the  history  of  cervical  injury,  the  pain  and  tenderness 
at  the  sides  of  the  uterus,  with  absence  of  peritonitic  symptoms  and  signs,  will 
render  such  a  suspicion  well  grounded.  AVhen  the  tumor  develops,  the  diagnosis  is 
usually  eas}'  and  its  discussion  will  be  taken  up  later. 

The  prognosis  is  usually  good.  With  proper  treatment  the  patient  has  a  mild 
course  of  fever,  and  aljsorption  of  the  exudate  takes  place.  Even  after  the  forma- 
tion of  abscesses  the  prognosis  as  to  life  is  good,  as  they  either  })reak  or  are  incised 
and  then  lieal.  In  the  larger  abscesses  the  prognosis  is  to  be  guarded,  as  they  some- 
times suppurate  for  months,  the  pelvis  becoming  riddled  with  sinuses,  and  the  pa- 
tient finally  dying  of  hectic  fever  and  exhaustion.

Made  of  thin  sheet-iron  and  covered  with  asbestos.     A  bag  of  calcium  chlorid  is  hung  inside  while  in  use,  to   absorb 

moisture,  but  must  not  be  near  the  bulbs  (see  Gellhorn). 


The  prognosis  as  to  health  is  not  so  good,  because  only  too  often  the  women 
have  ]3ermanent  backache,  leukorrhea,  or  disturbed  pelvic  circulation — dysmenor- 
rhea— and  symptoms  of  uterine  displacements.  The  scars  may  contract  and  cause 
pressure  on  the  nerves  (neuralgias  and  paralysis)  or  on  the  ureters,  producing 
hydronephrosis, — which  the  exudate  may  also  do, — or  traction  on  the  bladder, 
and  cause  tenesmus  and  incontinence,  or  on  the  rectum,  making  a  stricture.  The 
uterus  is  sometimes  drawn  to  different  parts  of  the  pelvis  and  fixed,  or  it  is  walled 
up  in  thick  connective  tissue  and  atrophies. 

Treatment  of  Pelvic  Cellulitis. — Besides  the  treatment  applicable  to  all  puerperal  infected 
cases,  attention  is  to  be  directed  to  the  prevention  of  the  spread  of  the  infection  and  to  the  evacu- 
ation of  pelvic  abscess,  or  to  means  to  hasten  the  absorption  of  large  exudates.  .Since  sitting  up 
and  getting  out  of  bed  are  known  to  cause  extension  of  the  disease,  manifested  by  chill,  increased 
pain,  and  fever,  the  patient  must  lie  C}uietly  on  her  back  during  the  acute  stages.  Vaginal  and 
intra-uterine  manipulations  are  unwise  and  harmful.  An  ice-bag,  a  hot-water  bag,  or  warm, 
moist  lieat  may  be  applied.  Cathartics  are  sparingly  used,  and  if  enemata  are  required,  they  may 
not  exceed  six  ounces  in  amount.  Operation  is  contraindicated  in  the  acute  stages,  even  if  the 
exudates  are  immense — reaching  above  the  navel.  If  the  symptoms — irregular  fever,  chills,  emaci- 
ation— point  to  suppuration  in  the  ma.ss,  or  if  fluctuation  Ls  demonstrated,  the  abscess  is  to  be 
opened.     As  a  rule,  there  need  be  no  precipitation  in  this  matter,  experience  having  shov\Ti  that 


846  PATHOLOGY  OF  THE  PUERPERIUM 

it  is  best  to  wait  until  tho  attark  on  tho  pus  cavity  has  become  easy  and  simple.  If  the  mass 
points  above  Poupart's  lijiament,  one  may  wait  until  the  ailhesion  of  the  dome  of  the  abscess  to 
the  abdominal  wall  is  firm  and  extensive,  thus  making  certain  that  the  general  peritoneal  cavity 
will  not  be  opened.  By  careful  ilissection,  layer  by  layer,  the  tissues  are  reflected  until  the  infil- 
trated wall  of  the  abscess  is  reached.  A  small  o})eninfr  is  made  here,  part  of  the  pus  evacuated, 
and  the  finger  inserted.  A  gentle  exploration  is  made  to  determine  the  extent  of  the  cavity,  and 
also  whether  it  will  be  better  to  drain  per  vaginam  also.  If  the  lowest  part  of  the  abscess  lies 
beneath  the  level  of  the  cervix,  the  vagina  may  also  be  opened  from  below,  guided  by  the  finger 
in  the  pus-pocket.  It  is  well  to  avoid  manipulation  at  the  sides  of  the  uterus  at  the  bases  of  the 
broad  ligaments,  because  of  the  large  vessels  here,  and  in  general  to  move  the  fingers  about  as 
little  as  possible  to  preserve  the  peritoneum.  Tubular  drainage  through  one  or  both  open- 
ings is  employed.  Healing  is  remarkably  ([uick,  unless  the  operation  was  done  too  early,  when 
time  may  be  required  for  an  undiscovered  pus-pocket  to  break  into  the  operative  sinus.  If  the 
abscess  bulges  in  the  posterior  culdesac,  it  is  attacked  here.  If  th(>  abscess  bulges  down  one  of 
the  lateral  fornices,  it  should  be  attacked  behind,  as  near  in  the  middle  line  as  possible,  to  avoid 
injuring  the  ureter  or  uterine  vessels  (vide  infra).  Since  most  cases  of  pelvic  cellulitis  heal  by 
absorption,  prolonged  expectancy  is  required.  When  amelioration  of  the  general  symptoms 
indicates  that  the  acuteness  of  the  local  process  has  subsided,  the  attendant  may  try  to  hasten  the 
absorption  of  the  exudates.  Hot  prolonged  vaginal  douches,  repeated  thrice  daily,  are  useful, 
also  the  hot-air  bath  of  the  pelvic  region,  recommended  by  Bier  and  Polano.  Such  an  apparatus 
is  easily  improvised  bj^  mounting  8  to  10  electric  lights  on  the  inside  of  a  cradle  lined  with  asbestos 
paper.  Gellhorn  describes  the  details  of  the  treatment,  which  can  be  heartily  recommended. 
The  patient  maj'  not  leave  her  bed  until  the  masses  have  almost  disappeared.  General  muscular 
tone  is  to  be  maintained  by  massage,  but  no  massage  is  given  the  pelvic  structures  for  several 
months  after  the  patient  is  up  and  about.  Then  massage,  gentle  at  first,  watching  the  effect, 
maj'  be  used  to  mobilize  the  uterus  and  tubes. 

Perimetritis. — Pelvic  peritonitis  accompanies  many  forms  of  local  puerperal 
infection,  as  parametritis,  endometritis,  uterine  abscess,  salpingitis.  Since  the 
inflammation  is  limited  to  the  pelvic  peritoneum,  we  may  conclude  that  the  infect- 
ing bacteria  are  of  low  virulence,  and,  as  a  rule,  the  staphylococcus,  the  gonococcus, 
and  saprophytes  are  usually  found.  Diplostreptococci  and  pneumococci  have  been 
present,  and  the  Bacterium  coli  also,  either  alone  or  in  symbiosis  with  the  others. 
Less  often  have  the  Bacillus  aerogenes  capsulatus,  the  pyocyaneus,  and  anaerobes 
been  detected.  They  cause  fetid  exudate  and  sometimes  gas.  Streptococci  of  low 
virulence  may  cause  a  mild  peritonitis.  If  of  high  virulence,  they  quickly  invade 
the  whole  peritoneum,  and  may  be  more  quickly  fatal  than  even  a  bacteremia.  The 
immense  surface  of  the  peritoneum  absorbs  the  toxins  of  the  streptococci  so  rapidly 
that  the  heart  and  nervous  system  are  overcome  within  a  few  days  or  even  a  few 
hours  after  inoculation. 

Causatio?!. — (1)  Traumatism,  as  where  the  uterus  is  much  squeezed  or  torn, 
may  have  a  mild  plastic  peritonitis  as  a  sequel,  and  the  most  dangerous  infections 
are  likely  to  follow  the  introduction  of  even  weak  bacteria  under  such  circumstances. 
In  cases  of  pressure  necrosis  of  the  soft  parts  between  the  head  and  the  l^ony  pelvis 
a  reactive  inflammation  usually  prevents  the  spread  of  the  inevitable  infection.  If 
a  careless  examiner  should  tear  the  surfaces  asunder,  or  if  alien  bacteria  are  intro- 
duced, a  rapidly  fatal  process  may  ensue.  (2)  Endometritis,  uterine  lymphangitis, 
pelvic  peritonitis,  a  secjuence  demonstrated  by  Tonnele,  explain  most  of  the  cases, 
and  sometimes  the  bacteria  (streptococci)  may  be  demonstrated  on  their  way  in  the 
lymph-spaces  through  the  uterus  (Fig.  741);  (3)  a  parametritis  may  develop  from 
a  torn  cervix  or  vagina,  and  the  bacteria,  without  meeting  a  reactive  inflammation 
in  the  broad  ligaments,  may  reach  the  peritoneum;  (4)  gonorrhea  may  cause,  in 
succession,  by  surface  extension,  endometritis,  salpingitis,  ovaritis,  pelvic  peri- 
tonitis, or  a  gonorrheal  pus-tube  may  burst  during  or  after  labor;  unless  the  strepto- 
coccus is  also  present,  such  infections  are  usually  mild,  with  a  strong  tendency  to 
localize;  (5)  rupture  of  an  appendiceal  abscess,  extension  of  a  perityphlitis  to  the 
pelvis,  or  the  bursting  of  a  collection  of  pus  anywhere  near  the  pelvis,  may  cause  a 
peritonitis  localized  to  this  region,  or  even  spreading  over  tho  whole  serous  surface; 
(6)  the  bacteria  may  reach  the  peritoneum  from  the  veins  in  the  broad  ligaments  in 
cases  of  streptococcous  thrombophlebitis.  It  is  clear,  therefore,  that  infection  may 
spread  to  the  pelvic  peritoneal  cavity  in  several  ways — via  the  lymph-vessels, — the

most  common, — l^y  surface  extension  along  the  tubes,  and  via  the  blood,  in  addition 
to  the  inoculation  of  the  serous  sac  by  direct  means,  the  introduction  of  the  bacteria 
by  the  hand  or  instruments,  or  the  rupture  of  infected  pus-sacs. 

Pathology. — The  pathologic  findings  are  the  same  as  are  usual  in  surgical  peri- 
tonitis. The  peritoneum 
is  reddened,  the  surface 
lusterless,  the  bowels  dis- 
tended, adherent  to  each 
other,  with  deep-red 
streaks  on  them  w^here  the 
surfaces  do  not  lie  directly 
apposed,  and  covered  with 
long  strings  of  fil^rinopus 
and  serous  exudate.  Be- 
tween the  matted  intes- 
tines a  seropus  is  found  in 
w'hich  float  whitish-yellow 
flakes  of  fibrin,  or  the  ex- 
udate may  be  all  fibrin  and 
pus. 

In  streptococcic  infec- 
tions the  serous  membrane 
may   be    only    reddened,      fig- 
there  being  little  exudate 
and   only   few   shreds    of 

fibrin.  The  tendency  to  localize  is  not  marked.  Subperitoneal  cellulitis  also  marks 
the  streptococcic  infections,  and  since  it  is  impossible  to  drain  these  spaces,  opening 
the  peritoneal  cavity  offers  little  hope  of  cure.     Blood  may  tinge  the  exudate,  which 

may  have  an  acrid,ipenetrating  odor, 
stinging  the  hand  immersed  in  it .  If 
the  infection  is  mild,  the  reaction  of 
the  serosa  may  limit  its  progress, 
which  nature  accomplishes  by 
throwing  out  a  coating  of  lymph 
which  binds  the  viscera  together. 
The  tubal  ostia  are  closed,  the  fim- 
briae being  matted  together.  The 
exudates  are  thus  confined  in 
pockets  bounded  by  adhesions,  and 
take  on  the  character  of  pus.  They 
may  break  into  neighboring  or- 
gans,— the  bladder,  vagina,  or  rec- 
tum,— and  they  may  creep  up  out 
of  the  pelvis,  usuallj'  on  its  pos- 
terior surface,  toward  the  dia- 
phragm, the  way  being  laid  out 
b}'  an  advancing  line  of  fresh  ad- 
hesions Avhich  prevent  the  spread 
of  the  infection  over  the  whole 
peritoneum.  Great  care  must  be 
exercised  in  palpating  such  cases, 
because  rough  pressure  may  rupture  the  adhesions,  flooding  the  peritoneal  cavity 
with  pus,  and  causing  death. 

The  usual  locations  for  these  collections  of  pus  are  in  Douglas'  culdesac,  and

high  up  at  each  side  of  the  uterus,  in  the  fold  between  the  infundibulopelvic  and 
broad  ligaments.  As  thej^  form  when  the  uterus  is  in  the  abdomen,  and  become  ad- 
herent at  the  level  at  which  they  form,  they  do  not  sink  with  the  uterus,  and,  there- 
fore, are  found  high  up.  This  distinguishes  them  from  parametritic  exudates, 
which  are  low,  nearer  the  vagina.  The  course  of  these  exudates  is  the  same  as  in 
parametritis — resolution,  absorption,  suppuration,  and  abscess.  The  latter  is  more 
common  than  in  parametritis.  The  former  takes  longer  than  in  parametritis,  and 
the  organs  are  left  more  deformed,  bound  down,  and  matted  together.  Frequently 
the  women  are  left  gynecologic  invalids,  and  are  almost  always  incural)ly  sterile, 
from  closure  of  the  tubes. 

If  the  infection  is  virulent,  the  streptococcus,  alone  or  in  symbiosis,  being  the

cause,  its  spread  is  very  rapid,  involving  the  whole  Iow(>r  abdomen  within  a  few  days 
or  even  onlj^  a  few  hours.  Seldom  is  there  time  for  the  peritonitis  to  become  uni- 
versal, because  the  patient  dies  from  the  inundation  of  the  system  by  toxins  rapidly 
formed,  and  absorbed  so  readily  from  the  immense  area  of  surface  of  the  peritoneum. 
The  exudate  in  cases  of  general  peritonitis  may  be  small  or  measure  several  quarts 
in  amount. 

If  the  infection  reached  the  peritoneum  from  the  endometrium,  it  may  be 
possible,  microscopically,  to  trace  the  bacteria  along  the  lymph-spaces.  At  the 
sides  of  the  uterus,  in  the  larger  lymph-vessels,  droplets  of  pus  may  be  found  on 
section,  and  the  peritoneum  over  the  uterus  shows  the  intensest  inflammation, 
redness,  and  fibrinopurulent  exudate. 

If  the  peritoneum  was  infected  by  way  of  the  tulies,  these  are  usually  dilated, 


CLINICAL   TYPES    OF   PUERPERAL    INFECTION  849 

forming  pus-sacs;  often  the  ovary  is  involved,  an  ovarian  abscess  resulting,  and 
nearly  always  the  process  is  mild,  being  limited  to  the  pelvis,  unless  improper  treat- 
ment transports  the  inft^ction  higher  u]). 

Symptoms. — Both  local  and  general  symptoms  and  signs  depend  on  the  mode 
in  which  the  infection  reaches  the  peritoneum.  The  bursting  of  a  pus-sac  is  almost 
always  attended  by  stormy  symptoms,  which  resemble  those  of  ruptured  ectopic 
pregnancy:  sharp,  severe  pain  at  the  site  of  the  abscess,  with  tenderness,  both 
rapidly  spreading  over  the  abdomen,  collapse,  followed  by  febrile  reaction  and  the 
evidences  of  peritonitis  mentioned  below.  If  the  peritonitis  follows  a  rupture  of  the 
uterus,  it  resembles  in  all  respects  that  following  a  severe  operation.  Usuallj'  the 
mode  of  entry  is  via  the  lymphatics  from  the  endometrium,  and,  therefore,  the 
symptoms  and  signs  of  endometritis  precede  those  of  peritonitis.  (See  Endometri- 
tis.) As  soon  as  the  peritoneum  becomes  involved  pain  becomes  a  prominent  symp- 
tom, localized  at  first  in  the  uterus  and  lower  abdomen,  spreading,  in  the  bad  cases, 
all  over  the  belly.  Vomiting  is  almost  a  constant  occurrence,  preceded  and  ac- 
companied by  continuous  nausea  and  sometimes  by  singultus.  The  vomit  is  at 
first  watery,  then  bilious,  and  at  last  stercoral  in  character,  and  the  action  is  sudden 
and  expulsive,  so  that  sometimes  the  bed  may  be  soiled  before  the  nurse  can  hand 
the  basin.  It  brings  no  relief  from  the  intense  nausea.  Constipation  is  the  rule  at 
first,  and  flatus  is  not  passed,  peristalsis  being  paralyzed.  This  paralytic  ileus  leads 
to  immense  abdominal  distention.  The  decomposition  of  the  intestinal  contents 
(by  the  Bacillus  coli,  the  perfringens,  pseudotetanus,  and  others)  leads  to  an  auto- 
intoxication, which  contributes  much  to  the  fatal  ending.  Later  in  the  disease  the 
bowels  sometimes  loosen,  and  exhausting,  foul  diarrheas  are  observed.  Thirst  is 
excessive,  restlessness  is  distressing,  but  usually  the  mind  is  clear  until  near  the  end, 
when  either  delirium  or  coma  supervenes,  or — and  this  is  most  ominous — a  state  of 
well-being — euphoria — begins. 

Examination  shows  the  patient  on  her  back,  with  the  knees  drawn  up,  both 
to  relax  the  muscles  and  to  take  the  weight  of  the  bed-clothes  off  the  bell}-.  Her 
expression  is  anxious,  her  color  at  first  reddened,  later  pale  and  gray  or  subicteric. 
The  face  at  first  presents  a  febrile  aspect,  but  later  this  is  replaced  by  one  of  col- 
lapse— sunken  eyes,  cold,  pointed  nose,  cool  forehead  bedewed  with  clammy  sweat 
— in  short,  the  typical  "facies  Hippocratica."  0^^^ng  to  the  constant  loss  of  body 
fluids  and  the  inability  to  replace  them,  the  tongue  soon  becomes  dry  and  brown, 
with  fetor  ex  ore  and  fuliginous  gums;  the  urine  is  reduced  in  amount  and  con- 
tains albumin,  casts,  indican,  and  often  the  l^acterium  causing  the  peritonitis. 
This  finding  shows  that  most  fatal  cases  are  really  septicemias.  The  temperature 
during  and  after  the  usual  initial  chill  is  raised, — often  as  high  as  105°  F., — the 
pulse  becomes  very  rapid,  and,  at  the  same  time,  of  a  peculiar  snappj-  character, 
and  later,  when  the  toxins  paralyze  the  vagus  and  heart  muscle,  uncountable  or 
filiform.  Respiration  is  quickened  and  costal,  first  l^ecause  of  the  toxinemia,  and, 
second,  because  of  the  immense  tympany  which  anchors  the  diaphragm  liigh,  and, 
third,  because  of  the  pain  in  the  belly.  Dilatation  of  the  veins  in  the  splanchnic 
area  causes  symptoms  of  shock. 

Rales  are  usually  heard  over  the  lower  part  of  the  lungs,  and  friction-sounds, 
if  the  patient  lives  long  enough  to  develop  a  pleuritis  also.  The  first  sound  of  the 
heart  early  loses  its  booming  quality,  the  toxins  affecting  the  muscle.  Friction  may 
be  heard  over  the  liver,  but  hardly  ever  over  the  lower  abdomen.  Gurgling  is  ab- 
sent (aperistalsis),  but  metallic  tinkling  may  be  found.  The  belly  is  tympanitic 
over  its  lower  part  at  first,  and,  as  the  infection  spreads,  it  may  be  immensely 
distended.  The  walls  are  usually  very  rigid  (defense  musculaire)  and  markedly 
tender.  Deep  pressure  may  sometimes  be  borne  Adthout  complaint,  but  sudden 
lifting  of  the  hand  causes  pain.  Remarkably,  but  true,  some  cases  of  peritonitis — 
and  these  are  usually  due  to  pure  streptococcous  infection — show  very  little  tender- 
54 


850  PATHOLOGY    OF   THE    PUERPERIUM 

ness,  hardly  any  rigidity,  and  are  attentled  by  little  i)ain.  It  seems  that  the  toxins 
produced  are  so  caustic  that  they  benumb  the  nerve-endings,  or  they  quickly  bring 
about  general  toxinemia  and  bacteremia,  with  insignificant  local  reaction.  In  such 
cases  of  latent  peritonitis  a  diagnosis  of  peritonitis  may  not  l)e  possible  during  life. 

If  the  inf(H'tion  is  virulent,  the  symptoms  grow  worse  rapidly,  the  tem]i(n-ature 
keeps  high  until  shortly  before  death,  when  it  drops,  the  pulse  mounting  in  fre- 
quency, the  two  curves  crossing  on  the  chart — the  ''cross  of  death";  collapse 
follows,  and  edema  of  the  lungs  or  exhaustion  closes  the  scene. 

If  the  patient  is  able  to  withstand  the  onslaught  of  the  infection,  the  symptoms 
and  signs  are  all  mikler  from  the  very  first  and  are  limited  to  the  pelvis.  Very  soon 
signs  of  localization  become  apparent — the  pain  logins  to  subside,  the  vomiting 
ceases,  the  bowels  begin  to  act,  the  movements  having  natural  color  and  odor,  the 
general  findings  improve — the  pulse  particularly,  by  slowing,  indicating  the  turn  for 
the  better.  It  is  not  safe  to  examine  these  cases  bimanually  for  several  weeks,  that 
is,  until  the  exudates  are  bound  off  by  firm  adhesions  and  resolution  in  them  is 
begun.  It  may  now  be  possible  to  find  a  fluctuating  tumor  in  the  culdesac  or  high 
up,  at  either  or  both  sides  of  the  uterus.  Great  care  must  be  exercised  in  palpating 
these  peritonitic  collections.  I  have  seen  two  deaths  result  directly  from  the  l)urst- 
ing  of  such  abscesses  into  the  hitherto  protected  general  peritoneal  cavity.  Should 
such  an  accident  occur,  the  belly  must  at  once  be  opened  and  drainage  above  and 
below  established. 

If  the  patient  recovers,  the  pelvic  organs  and  intestines  are  matted  together, 
the  uterus  distorted  and  displaced,  the  tubes  kinked  or  occluded,  the  ovaries  are 
involved  in  a  mesh  of  adhesions  and  develop  a  tendency  to  become  cystic,  and  the 
pelvic  circulation,  as  in  parametritis,  is  disturbed.  If  a  pyosalpinx  or  ovarian  ab- 
scess is  the  residuum,  the  recovery  is  never  complete.  As  a  result  of  all  these  changes 
the  woman  usually  dates  life-long  invalidism  from  her  confinement,  her  symptoms 
being  pain  in  the  pelvis  and  back,  bearing  down,  inability  to  do  her  duties, 
neurasthenia,  sterility,  dyspareunia,  dysmenorrhea,  menorrhagia,  leukorrhea,  and 
the  signs  of  pelvic  congestion.  Mild  cases  of  perimetritis — so  mild  as  to  escape 
the  notice  of  all  but  the  acute  observer — may  leave  such  traces,  and  a  goodly  pro- 
portion of  the  gynecologist's  clientele  is  of  this  class. 

Diagnosis. — It  is  not  always  possible  to  differentiate  between  a  parametritis 
and  a  perimetritis  in  the  early  stages — indeed,  they  often  occur  together.  Chill  and 
high  fever  are  common  to  both,  but  the  chill  is  usually  more  pronounced  in  the 
cellulitis,  but  the  general  impression  is  of  a  less  severe  illness.  Nausea,  singultus, 
and  vomiting,  with  prostration,  rapid  pulse,  excessive  local  pain  and  tenderness,  with 
increasing  and  spreading  abdominal  rigidity,  point  to  peritonitis.  The  exudate  in 
parametritis  is  usually  low  down  and  unilateral ;  that  of  peritonitis  is  higher  up  and 
more  often  posteriorly  than  at  the  side;  the  cellulitis  shows  a  brawny,  hard  infil- 
trate, which  softens  late;  the  perimetritic  exudation  is  soft  from,  the  start.  The 
shape  of  the  pelvic  tumor  gives  useful  indications.  In  cellulitis  the  infiltrations 
follow  the  layers  of  fascia  and  the  ligaments;  in  peritonitis,  the  peritoneal  pockets 
are  first  filled  with  the  exudates,  Douglas'  culdesac,  and  the  regions  of  the  ovaries. 
Pyosalpinx  and  ovarian  abscess  usually  cannot  be  palpated  out  of  the  pelvic  in- 
flammatory masses  in  the  early  stages.  After  a  few  weeks  the  parametritic  infil- 
trates are  absorbed,  and  then  one  may  be  able  to  outline  the  structures.  The 
aspirating  needle  may  be  used  to  discover  the  natun;  of  fluid  in  the  i)erit()neal 
cavity. 

Frogyiosis. — This  should  always  be  withheld  in  ihc  early  part  of  the  illness,  be- 
cause we  are  usually  in  ignorance  of  the  nature  of  th(^  infecting  bacterium  and  of  the 
road  it  takes  to  the  peritoneum.  Streptococcic  infections  are  particularly  fatal: 
they  seldom  localize,  and  the  absorption  of  the  toxins  is  so  rapid  that  the  heart 
muscle  and  nervous  system  are  quickly  overcome.     Staphylococcic,  gonococcic, 


CLINICAL   TYPES    OF   PUERPERAL   INFECTION 


851 


and  colon  infections  are  much  more  favorable.  All  depends  on  the  ability  of  the 
peritoneum  to  wall  off  the  advancing  bacteria  by  the  layer  of  leukocytes,  the  throw- 
ing out  of  lymph,  and  matting  of  the  pelvic  viscera  together.  Symptoms  and 
signs  which  indicate  such  a  process  justify  us  in  giving  a  favorable  prognosis.  The 
pulse  gives  us  the  most  reliable  information  of  what  is  going  on  in  the  peritoneum; 
next,  the  general  condition  of  the  patient.  Low  blood-pressure  is  of  bad  omen. 
Slowing  of  the  pulse  is  a  good  sign. 

Treatment  of  Peritonitis. — At  the  beginning  it  may  not  be  possible  to  differentiate  a  peritoni- 
tis from  a  cellulitis,  and  the  treatment,  th(>refore,  will  bo  tlie  same  for  })oth.  If  the  ease  starts 
out  as  a  violent,  acute  puerperal  peritonitis,  very  little  can  be  expected  from  any  treatment. 
Simply  openinji;  the  al)domen  in  the  midline  above  the  pubis,  or  posterior  colpotomy,  will  not  do 
much  harm.  If  such  an  incision  reveals  a  ruptured  uterus  or  a  burst  pus-sac  (pus-tube,  appendi- 
citis, etc.),  appropriate  treatment  is  made;  otherwise  several  soft-rubber  drainage-tubes  are  placed 


Fig.  755. — Opening  Abscess  in  Culdesac. 


radially  in  the  abdomen,  one  rcachins  to  tlie  culdesac,  and  a  large  moist  dressing  is  applied.  Some 
operators  irrigate  the  peritoneal  cavity  with  normal  salt  solution,  but  most  men  are  opposed  to 
this,  as  well  as  to  eventration,  because  it  shocks  the  patient  too  much.  Lately  the  injection  of 
100  to  300  c.c.  of  a  1  per  cent,  solution  of  camphor  in  oil  has  been  recommended.  If  the  course 
of  the  disease  is  milder, — more  chronic, — more  may  be  expected  of  operation,  and  it  is  these  cases 
which  give  the  better  statistics — for  example,  Bumm,  .^0  i)er  cent.;  Leopold,  2.'>  per  cent.;  Jcan- 
nin,  oO  per  cent,  mortality.  The  gonococcus,  the  staphylococcus,  or  a  mild  streptococcus  are 
usually  found  here.  My  own  experience  with  operation  in  acute  ditTusing  puerperal  peritonitis 
shows  only  one  recovery  in  10  women  drained.  \Mien  there  is  a  tendency  to  locaUzation,  it  is 
safer  to  wait  until  the  abscess  has  formed  and  then  drain  it,  usuall\'  from  below. 

The  vagina  is  exposed  by  short,  broad  specula,  the  cervix  steadied,  but  not  pulled  down, 
and  with  a  vulsellum  forceps  the  posterior  fornix  is  incised  cleanlj'  with  a  sharp  scissors  or  scal- 
pel, the  tissue  to  be  cut  being  held  by  long  tissue  forceps,  and  the  opening  enlarged  by  stretching 
with  an  S-inch  artery  clamp.  The  sac  may  not  he  punched  into — -every  effort  must  be  taken  to 
avoid  increasing  its  tension,  because  a  delicate  adhesion  in  its  roof  may  give  way  and  pus  will  es- 
cape above  into  the  general  peritoneum,  an  accident  which  even  the  inunediate  laparotomy  may 
not  prevent  being  fatal.  After  the  pus  is  evacuated  one  or  two  fingers  may  be  passed  into  the 
cavity,  and  gentle  palpation  of  the  walls  made,  but  it  is  unwise  to  try  to  isolate  a  pus-tube  unless 
it  is  within  easy  reach,  when  it  may  be  drained  through  the  same  opening.     An  ovarian  abscess 


852 


PATHOLOGY  OF  THE  PUERPERIUM 


is  treated  similarly.  It  is  hazardous  to  remove  the  pus-sacs  in  the  acute  stages.  It  is  better  to 
reheve  the  dauber  by  vaginal  tlrainage,  if  necessary,  and  jjost  j)()ne  the  radical  operation  for  several 
montlis  until  the  pus  has  become  sterile.  If  ceUotomy  is  imperative,  the  sac  may  be  fixed  to  the 
abdominal  wall  and  opened  three  days  later  with  the  Paquelin  cautery.  The  ilrainage-tube 
shoukl  be  left  in  place  for  a  day  after  it  has  ceased  to  drain,  and  the  opening  kept  open  a  few  days 
longer  with  a  bit  of  gauze.  Irrigations  are  unncn-essary  and  harmful.  The  patient  is  kept  in  the 
Fowler  position  for  a  few  days.  In  the  very  chronic  pelvic  sinuses  vaccine  therapy  may  be  useful. 
Vaginal  douches  to  hasten  the  absorption  of  exudates  and  the  hot-air  bath  may  be  used  in 
chronic  cases,  but  are  not  so  successful  as  in  parametritis.  Massage  may  be  employed  in  the 
latest  stages. 

Bacteremia  is  an  acute  infectious  disease,  clue  to  the  entrance  into  the  blood  of 
microbes,  usually  the  Streptococcus  pyogenes,  but  sometimes  of  other  cocci  and

bacteria,  and  their  toxins,  which  produce  a  dissolution  of  the  blood,  degenerative 
changes  in  the  organs,  and  the  .symptoms  of  a  rapitl  intoxication.  The  terms  "septi- 
cemia" and  "sepsis,"  from  the  Greek  aiixpLs,  meaning  decay,  have  gained  such 
general  usage  as  applied  to  all  forms  of  severe  infection  that  they  will  probablj^  be 
retained.  Septicemia  is  synonymous  with  bacteremia,  which  term  should  replace 
it.  The  essential  quality  of  these  infections  is  the  invasion  of  the  ])lood-stream  by 
the  bacteria.  Most  often  the  strej^tococcus  is  causative,  but  the  pneumococcus, 
the  staphylococcus,  the  Bacillus  pyocyaneus,  the  gonococcus,  the  liacillus  aerogenes 
capsulatus,  and  others  have  been  found.     Entrance  to  the  blood  is  gained  in  two

ways — via  the  lymphatics,  the  most  usual,  and  via  the  blood-vessels,  particularly 
the  veins,  and  sometimes  in  both  ways  at  the  same  time.  Differing  clinical  pictures 
are  produced,  depending  on  the  mode  of  invasion,  and  it  is  often  possible  to  desig- 
nate the  symptoms  appertaining  to  each  form.  Just  as  often  the  pictures  are  in- 
distinct, partaking  of  the  characters  of  the  two  affections.  The  lymphatic  form  of 
bacteremia  usually  develops  from  an  endometritis,  the  bacteria  passing  along  the 
lymph-spaces  of  the  uterus  and  broad  ligaments  into  the  blood,  or  out  onto  the  sur- 
face of  the  peritoneum,  causing  peritonitis,  pleuritis,  etc.  The  vascular  form  of 
bacteremia  begins  as  a  metrophlebitis,  usually  at  the  placental  site,  with  thromboses 
in  the  veins.  Fromjthe^e  infected  thrombi  the  bacteria  get  into  and  multiply  in 
tiie.bkiiKM^ca±ingJrL-distant  or^ns, — the  eye,  the  brain,  the  cord,  the  joints,  the 
valves  of  the  heart,  etc., — in  short,  a  true  bacteremia  develops.  In  such  cases  the 
local  symptoms  may  be  insignificant.  A  slower  form  of  general  infection  occurs  in 
the  metrophlebitic  cases.  The  thrombi  suppurate, — a  condition  not  common  with 
the  streptococcus, — and  Ijits  of  infected  fibrin  or  microscopic  droplets  of  pus,  or

even  larger  pieces  of  thrombus,  may  break  off  and  be  swirled  away  by  the  blood- 
stream to  the  lungs,  the  kidneys,  the  brain,  etc.,  where  they  set  up  new  foci  of  sup- 
puration. This  last  disease  has  been  named  pyemia,  but  there  is  almost  never  any 
''pus  in  the  blood."  Yon  Herff  has  suggested  the  term  "metastatic  bacteremia" 
for  this  affection.  Often  it  begins  as  a  septicemia,  developing  the  characters  of  a 
pyemia  later. 

Pathology  of  Septicemia. — A  bacteremia  may  follow  an  insignificant  lesion  lo- 
cated at  any  part  of  the  genital  tract.  Even  a  frenulum  tear  may  allow  the  virulent 
streptococcus  rapid  access  to  the  blood.  Again,  the  resistance  of  the  patient  may 
be  broken  down  only  after  a  long  fight  or  after  ill-advised  local  treatment— that  is, 
a  process  that  was  limited  to  the  surface  is  allowed  to  become  invasive.  An  ex- 
ample of  this  is  the  severe  bacteremia  which  usually  follows  curetage  in  cases  of 
streptococcic  endometritis. 

In  the  lymphatic  varieties  of  septicemia  the  findings  at  autopsy  are  quite 
typical:    (1)  Endometritis  gangrenosa,  or  metritis  desiccans,  often  the  whole  tract 


854 


PATHOLOGY  OF  THE  PUERPERIUM 


being  covered  by  a  grayish,  sloughing,  diphtheroid  exudate.  (2)  Parametritis  and 
lymphangitis,  the  lymph-vessels  at  the  sides  of  the  uterus  being  filled  -with  jnirulent 
fluid  which  exudes  from  the  cut  surface;  the  connective  tissue  may  l)e  infiltrated 
and  edematous,  and  this  cellulitis  may  spread  so  fast  and  far  as  to  justify  the  name 
Virchow  gave  it — erysipelas  puerperalis  malignum  internum.  The  changes  in  the 
parametria  may  be  simply  a  serous  infectious  edema,  or  necrosis  may  occur — a  real 
phlegmon.  (3)  Pelvic  peritonitis,  then  general  peritonitis.  (4)  If  the  patient  lasts 
long  enough,  pleuritis  and  pericarditis.  (5)  Gastritis  submucosa — gastritis,  enter- 
itis, and  colitis.  (6)  General  pathology  of  acute  in- 
fectious disease — swollen  spleen,  fatty  degeneration 
and  cloudy  swelling  of  muscles,  and  especially  of  the 
heart,  liver,  and  kidneys.  Bacteria  in  immense 
numbers  are  found  in  the  minute  capillaries  and 
lymphatics  of  these  organs.  (7)  The  findings  of 
the  metastases  in  the  lungs,  heart,  brain,  joints, 
connective  tissue,  and  so  on. 

In  the  vascular  forms  of  bacteremia  the  lym- 
phatics are  not  involved  at  all,  or  to  a' decidedly 
less  extent.  The  veins  of  the  placental  site  are 
filled  with  large  thrombi,  which  are  swarming  with 
bacteria.  The  bacteria  erode  the  endothelium  of 
the  vessel;  fibrin  is  deposited  on  the  surfaces;  the 
lumen  is  occluded,  and  the  process  advances  through 
the  venous  plexuses  of  the  broad  ligament  into  the 
spermatic  and  iliac  veins,  even  to  the  cava.  From 
the  surface  of  these  thrombi  bacteria  are  liberated 
in  the  blood-stream,  and  if  they  are  strong  enough 
to  multiply  in  it,  a  fatal  bacteremia  will  result.  If 
the  bacteria  are  less  virulent  or  of  a  more  pyogenic 
character,  the  process  is  more  chronic,  the  thrombi 
undergo  puriform  softening,  and  solid  bits  or  drop- 
lets of  pus  break  loose,  and,  floated  by  the  blood- 
stream, lodge  in  distant  portions  of  the  body,  set- 
ting up  new  foci  of  suppuration.  This  condition 
has  been  called  pyemia,  and  will  be  considered 
directly. 

Symptoms.- — A  period  of  incubation  of  from  one 
to  three  days  usually  precedes  the  outbreak  of  the 
severe  symptoms.  In  rare  cases  threatening  ]iro- 
dromes  appear  within  a  few  hours  after  the  inocula- 
tion, and  the  woman  gets  very  sick  and  may  die  be- 
fore thirty-six  hours  have  passed  (Fig.  759) .  Ordin- 
arily, the  prodromal  stage  is  manifested  by  the  signs 
and  symptoms  of  the  local  process  from  the  site  of 
which  the  bacteria  gained  access  to  the  blood.  The 
reader  is  referred  to  the  chapters  on  Endometritis,  Parametritis,  etc.,  for  these 
symptoms.  It  is  often — indeed,  usually  — impossible  to  determine  when  and  how 
the  germs  get  into  the  blood.  Schottmiiller,  using  anaerobic  methods,  has  been 
able  to  cultivate  the  streptococcus  from  the  l)lood  in  many  cases  where  the  diag- 
nosis of  a  purely  local  process  had  been  made.  That  a  serious  bacteremia  exists 
will  be  apparent  from  the  following  syndrome,  though  it  must  be  admitted  that 
the  absorption  of  toxins  in  large  amounts  will  produce  the  same  conditions. 

A  severe  chill,  lasting  from  five  to  thirty  minutes,  ushers  in  the  affection;    the 
temperature  rises  rapidly  to  103°  or  104°  F.,  and  tlu;  pulse  jumps  at  once  above

120,  soon  attaining  a  frequency  between  this  and  160.  At  first  bounding,  it  soon 
becomes  soft  and  compressible,  the  toxins  weak(>ning  the  heart  muscle.  Owing  to 
the  destruction  of  the  red  blood-corpuscles  the  oxygen-carrying  power  of  the  blood 
is  diminished,  the  patient  exhibits  a  marked  pallor,  and  the  respirations  are  hurried. 
In  some  respects  the  disease  resembles  acute  leukemia.  Tympany  and  peritonitis 
still  further  compromise  the  breathing.  Very  early  in  the  attack  malaLse  Ls  decided 
— the  woman  appears  as  if  stricken  down,  is  apprehensive  of  a  dangerous  illness, 
even  of  impending  death,  the  change  being  sudden  and  significant.  Headache  and 
sleeplessness  are  constantly  complained  of — the  latter,  in  the  absence  of  sufficient 
cause,  being  particularly  ominous.  While  the  mind  may  remain  clear  until  near  the 
end,  this  is  unusual — mild  delirium,  tlelirium  in  somnolence,  and  often  maniacal 
outbursts  characterize  the  last  days.  Acute  endocarditis  is  almost  always  marked 
b}'  delirium. 

Symptoms  of  peritonitis — nausea,  vomiting,  pain,  etc. — very  soon  begin,  and 
the  facies  Hippocratica  shows  that  the  fatal  termination  is  not  distant.  The  lochia 
are  usually  profuse  and  putrid,  the  result  of  a  gangrenous  endometritis,  though 
sometimes  the  lochia  are  scant.  The  odor  is  not  marked,  being  pungent  to  the 
nostril.  The  puerperal  wounds  become  necrotic.  Signs  of  peritonitis — tenderness, 
tympany,  spreading  rigidity,  ileus,  etc. — begin,  and  if  the  patient  lives,  become 
marked,  and  the  picture  becomes  one  of  virulent  peritonitis.  While  the  tempera- 
ture goes  down,  the  pulse  rises  higher,  and  the  tongue  becomes  drj' and  fuliginous. 
A  peculiar  fruity  odor — sweet,  sickening — may  be  noticed  about  the  patient.  After 
three  or  four  days  the  patient  feels  easier,  but  the  objective  signs  are  worse.  Her 
body  is  cold,  sometimes  even  the  trunk,  and  bedewed  with  a  cold  sweat ;  she  is  of  a 
yello\\ash  color,  while  the  translucent  parts,  for  example,  nose  and  ears,  are  a  leaden 
gray.  Consciousness  is  sometimes  retained  until  a  few  hours  before  death,  which 
usually  occurs  in  coma,  preceded  by  edema  of  the  lungs.  Oftener,  the  course  is 
marked  by  delirium,  and  in  cases  where  the  liver  is  much  involved,  the  s^-mptoms 
may  resemble  those  of  acute  yellow  atrophy  of  the  liver  (q.  v.).  If  the  patient  lives 
long  enough,  a  pleuritis  develops. 

The  disease  lasts  for  from  two  to  ten  days.  It  is  especially  virulent  if  it  be- 
gins during  labor,  when  the  course  is  usually  short  and  violent — "foudroyante,"  as 
the  French  say.  Eruptions  on  the  skin  resembling  scarlatina  occasionally  occur. 
This  has  nothing  in  common  ^^ith  true  scarlatina,  though  the  puerjiera,  hke  every 
one,  may  contract  this  disease.  It  may  be  difficult  to  make  the  differential  diag- 
nosis. Pustular  and  vesicular  eruptions  (containing  the  infecting  organism)  are 
ver>'  rare,  as  also  are  petechise  and  hemorrhages  in  the  skin,  all  of  which  denote  a 
very  dangerous  form  of  the  malady.  A  marliling  of  the  skin  which  shows  the 
course  of  the  superficial  veins  is  of  bad  omen — it  indicates  general  hemoh'sis.  An 
erysipelatous  inflammation  may  begin  at  the  vulva  and  invade  a  large  part  of  the 
trunk  and  legs.  Albuminuria  is  the  rule,  with  casts,  kidney  epithelium,  and  the 
causative  bacterium.  Sometimes  severe  diarrheas,  fetid  and  acrid,  still  further 
reduce  the  strength  of  the  patient.  ThjToiditis  is  not  a  rare  complication.  Ex- 
amination of  the  blood  reveals  the  streptococcus  or  other  organism  in  the  majority 
of  the  cases,  especially  if  the  bacteremia  is  of  vascular  origin.  In  the  l^^nphatic 
forms  the  toxins  from  the  parametrium  and  peritoneum  may  kill  the  patient,  with 
little  invasion  of  bacteria  in  the  blood.  Leukocytosis  is  usually  present,  but  its 
absence  does  not  signify  nnich  (ride  infra).  There  is  a  hemoglobinemia  and  an 
increase  of  the  i^olynuclears  and  mononuclears,  with  a  decrease  of  the  eosinophiles 
and  of  the  reds. 

If  the  patient  is  able  to  overcome  the  attack  of  the  bacteria,  it  is  evidenced  by 
a  degree  of  mildness  of  the  sjanptoms  and  a  protracted  course  of  the  disease.  The 
initial  chill  is  occasionally  repeated,  but  rarely  more  than  once;  the  temperature 
shows  greater  remissions,  the  pulse  keeps  a  lower  level,  the  patient  feels  some  im- 


856  PATHOLOGY   OF   THE    PUERPERIUM 

proveinent  in  her  condition,  sleeps  more,  her  skin  becomes  covered  with  a  warm 
perspiration,  the  peritoneal  symptoms  subside  or  do  not  even  appear,  the  kidneys 
act  more  freely,  the  bowel  movements  become  normal,  and  the  disease  terminates, 
usually  rapidly,  by  lysis. 

If  embolic  processes  are  lit  up,  the  symptoms  and  signs  are  those  peculiar  to  the 
organ  and  location  of  the  new  inflammations.  One  way  that  acute  bacteremias 
terminate — and  this  is  true  of  the  vascular  variety — is  by  passing  over  into  a  sub- 
acute or  chronic  state  of  pyemia.  Some  authors  call  these  conditions  septicopyemia. 
The  diagnosis,  prognosis,  and  treatment  will  be  discussed  later. 

Septic  Endocarditis. — This  usually  complicates  the  severer  bacteremias,  or 
septicopyemia,  but  may  occur  after  a  mild  local  affection,  or,  rarely,  without  dem- 
onstrable local  lesions.  The  bacteria  settle  on  the  valves,  oftenest  of  the  left 
heart,  causing  ulceration  of  same.  The  disea,se  is  marked  by  the  presence  of  miliary 
embolic  abscesses  in  the  brain,  liver,  kidneys,  etc.  An  endocardium  that  is  already 
diseased  is  more  prone  to  infection,  and  chlorosis  seems  to  favor  it,  too. 

Symptoms. — Severe  rigor,  high  and  continuous  fever,  very  rapid  pulse,  cerebral 
sj'mptoms,  muttering  delirium,  stupor,  or  even  acute  delirious  mania,  and,  later, 
symptoms  of  meningitis;  retinal  hemorrhages  in  80  per  cent.  (Litten);  diarrhea; 
hemorrhages  under  the  skin;  scarlatiniform  eruptions  or  blisters.  The  disease 
lasts  from  two  to  twenty-eight  days,  and  often  simulates  typhoid,  presenting  roseola, 
enlarged  spleen,  and  typhoid  tongue.  The  heart-findings  are  usually  equivocal. 
Sometimes  sudden  death  occurs. 

The  diagnosis  is  not  easy  in  the  absence  of  a  local  cause  for  the  high  fever  and 
the  rapid  pulse.  Severe  sickness,  marked  nervous  symptoms,  retinal  hemorrhages, 
repeated  chills  without  determinable  emboli,  indicate  a  severe  bacteremia. 

The  jyrognosis  is  bad.     The  treatment  is  symptomatic. 

Pyemia,  septicopyemia,  metastatic  bacteremia,  are  all  names  for  a  chronic  form 
of  sepsis  characterized  by  repeated  chills,  high  fever  with  deep  remissions  and  inter- 
missions, and  marked  tendency  to  metastatic  pus-formation.  The  essential  path- 
ology of  this  form  of  infection  is  a  metrophlebitis  with  extension  along  the  veins  of 
the  broad  ligaments  into  the  spermatic,  the  hypogastric,  and  the  iliac  veins,  even 
to  the  vena  cava,  attended  by  the  formation  of  thrombi,  from  which  bacteria,  bits 
of  fibrin,  and  droplets  of  pus  are  released  and  carried  away  in  the  blood-stream,  to 
find  lodgment  in  distant  organs,  there  setting  up  purulent  processes.  The  thrombi 
in  these  infections  are  large,  and  undergo  puriform  degeneration,  while  in  the  acute 
bacteriemia  they  are  not  so  extensive  and  do  not  l)reak  down,  but  supply  myriads  of 
germs  to  the  blood.  These  thrombi  are  found  mainly  in  the  spermatic  vessels  if  the 
infection,  as  is  usual,  gained  entrance  at  the  placental  site  in  the  fundus.  If  the 
main  infection  is  in  the  lower  part  of  the  uterus,  or  if  the  placental  site  was  low 
(placenta  praevia),  the  uterine  veins  first,  and  then  the  hypogastric  and  internal 
iliac  or  the  femoral  are  involved,  causing  one  form  of  phlegmasia  all)a  dolens  (Fig. 
756).  There  is  sometimes  a  periphlebitis  around  the  veins  in  the  broad  ligaments, 
and  from  this  a  peritonitis  or  a  parametritis  may  develop,  which  extends  upward  or 
down  the  thigh,  the  latter  causing  another  form  of  phlegmasia  alba  dolens  (g.  v.). 
The  uterus  will  show  the  changes  resulting  from  the  attack  of  the  bacteria, — either 
an  endometritis  or  a  phlebitis, — and  involution  will  be  retarded.  Sometimes  in- 
volution is  normal,  the  disease  being  located  only  at  the  placental  site,  which  shows 
large  and  infected  thrombi.  The  bacteria  involved  are  again  frequently  strepto- 
cocci of  a  low  gi-ade  of  virulence  or  the  pyococci,  but  the  others  mentioni^d  above 
may  also  be  causative. 

Symptoms. — Often  the  symptoms  of  a  local  infection,  especially  that  of  endo- 
metritis, precede  the  development  of  pyemia,  and  this  process  may  have  subsided 
and  the  patient  already  have  been  called  convalescent  when  the  first  chill  announces 
a  new  complication.     Again  the  pueqiera  may  have  had  an  apparently  normal

occur  within  a  few  hours  or  the  next  day,  and  these  are  repeated  daily  for  a  varia- 
ble lenjith  of  time.  One  of  my  cases  had  more  than  100  chills.  The  severest  forms 
of  infection  have  the  fewest  numlier  of  chills,  and  the  number  of  rigors  cannot  be 
foretold.  It  is  believed  that  each  one  indicates  that  a  bit  of  thrombus  has  broken 
off,  or  at  least  that  the  blood  has  gained  a  new  supply  of  bacteria  or  toxins.  The 
bacteria  are  usually  most  easily  found  in  the  blood  during  the  chill  (Warnekros). 
It  is  impossible  to  locate  the  embolism  of  every  chill.  The  temperature  is 
very  irregular;  the  pulse-curve  follows  that  of  the  fever,  unless  an  emlwlism  occurs 
in  a  vital  organ  (Fig.  760).  Leukocytosis  is  the  rule.  The  course  of  the  disease 
is  very  chronic,  lasting  from  three  weeks  to  three  months,  or  even  as  long  as  a 
year.  At  first  the  general  condition  is  little  affected,  but  sooner  or  later  the  blood 
suffers,  the  strength  wanes,  and  a  hectic  condition  and  inanition  develop.  The 
skin  becomes  waxy-gray,  the  pulse  weak  and  rapid,  bed-sores  develop,  and  the 
patient  may  die  of  exhaustion  in  four  to  twelve  weeks  without  metastases  devel- 
oping. IVIetastases  are  the  rule,  however,  and  they  may  protract  the  course  of  the 
disease  as  long  as  eight  months.     The  most  common  metastases  are: 

(a)  Lungs. — Emboli  here  are  indicated  by  pain  in  the  chest,  cough,  bloody, 
sometimes  purulent,  expectoration,  dyspnea,  and  the  signs  and  symptoms  of  pleur- 
isy, abscess,  or  pneumonia.  Later,  gangrene  of  the  lung  may  occur.  If  the  em- 
bolus is  large,  it  may  plug  one  of  the  larger  pulmonary  vessels  and  cause  sudden 
death.  If  the  embolus  is  exceedingly  small,  it  may  pass  through  the  large  pul- 
monary capillaries  and  lodge  in  the  brain,  kidneys,  etc.  If  the  foramen  ovale  is 
patent,  the  emboli  may  pass  directly  into  the  greater  circulation. 

(6)  Joints. — When  the  joints  are  affected,  the  usual  signs  of  arthritis  are  present. 
Suppuration  and  complete  disorganization  do  not  always  follow;  sometimes  a 
serous  effusion  is  the  only  finding,  and  it  is  reabsorbed,  but  may  leave  adhesions, 
contractures,  and  partial  disability.  The  knee  is  most  often  affected,  and  the  large 
joints  usually,  but  not  one  is  exempt. 

(c)  Subcutaneous  tissue  anywhere  may  be  the  seat  of  an  abscess,  which  is  shown 
by  the  usual  signs.  Fochier  noticed  that  these  abscesses  seemed  to  have  a  curative 
effect,  and  he  induced  them  artificially  as  a  therapeutic  measure. 

(d)  Kidneys. — Albuminuria  is  constant  in  the  bad  cases.  Emboli  here  are 
shown  by  pain,  bloody  urine,  and  the  usual  course  of  a  pyonephrosis. 

(e)  Eyes. — Two  forms  occur.  Retinal  hemorrhages,  common  with  acute  endo- 
carditis, and  panophthalmitis,  with  complete  disintegration  of  the  eyeball. 

(/)  Thyroiditis,  Parotitis. — Metastases  of  the  kidney,  eye,  and  thyroid  are 
of  very  evil  omen,  but  are  not  absolutely  fatal.     Meningitis  is  always  fatal. 

If  the  veins  of  the  pelvis  are  much  involved,  edema  of  the  legs  is  noticed,  and 
the  abdominal  wall  veins  enlarge  for  the  collateral  circulation.  Ascites  may  be  pres- 
ent. On  the  other  hand,  all  three  may  be  absent,  with  very  extensive  throml)osis. 
Gangrene  of  the  flesh  of  the  calves  and  posterior  aspects  of  the  thighs,  leaving  deep 
and  eroding  l)ed-sores,  occurs  in  very  chronic  cases,  and  the  puerpera  will  be  made  a 
bed-  or  chair-ridden  invalid  for  life. 

The  diagnosis  at  first  may  be  in  doubt,  liut  soon  the  repeated  chills,  the  zigzag 
temperature-chart,  and  the  local  findings  will  clear  the  situation.  \'aginally,  the 
uterus  may  be  normal,  but  usually  it  is  enlarged  and  slightly  tender.  At  one  or 
both  sides  the  fornices  may  be  found  swollen  and  sensitive ;  indeed,  the  thrombosed 
veins  may  sometimes  be  felt  as  solid,  worm-shaped  cords.  Deep  pressure  at  the 
sides  of  the  uterus  from  the  belly  always  elicits  tenderness,  and  the  same  may  be 
present  undc^r  Poupurt's  ligaments.  Prognosis  antl  treatment  will  be  considered 
later. 

Phlegmasia  Alba  Dolens. — This  is  a  term  rather  loosely  applied  to  several 
different  pathologic  conditions.  Literally  it  means  a  painful  white  inflammation, 
and  is  applied  to  such  occurring  in  the  legs  and  thighs,  although  equally  applicable 


CLINICAL   TYPES    OF   PUERPERAL   INFECTION  859 

to  the  same  condition  occurring  in  the  arms.     The  following  forms  are  observed  in 
practice : 

(1)  Simple  thrombosis  of  the  saphenous  and  femoral  veins  or  of  the  iliac,  with 
edema  of  the  extremity  beginning  at  the  foot  and  extending  to  the  trunk,  but  not 
onto  it,  attended  by  very  slight  fever,  little  pain,  and,  in  general,  very  mild  symptoms. 
The  skin  is  cool,  translucent,  and  mottled,  or  marbled  with  distended  veins.  Punc- 
ture would  show  a  thin  serum.  These  cases  have  been  called  mechanical  thrombo- 
ses, and  have  been  explained  b}'  the  stasis  of  the  blood  in  the  pelvic  and  crural  veins 
during  ])regnancy  and  the  puerperium,  the  long  rest  in  the  recumbent  posture,  the 
anemia,  the  hyperinosis  of  pregnancy,  marasmus,  etc.,  but  the  author  believes  that 
they  are  always  due  to  a  mild  infection,  and  that  it  is  a  rapidly  advancing  endo- 
phlebitis.  The  origin  of  this  infection  may  be  remote  from  the  site  of  the  throm- 
bosis, and  may  have  healed,  examples  of  which,  from  my  own  observation,  are  ulcer 
of  the  ankle  and  infected  perineum.  At  an  autopsy  in  Menna  on  a  woman  who  died 
of  pulmonary  embolism  after  a  simple  perineorrhaphy  the  pelvic  and  femoral  veins 
were  found  filled  with  clots,  and  their  origin  could  be  traced  to  the  infected  wound  in 
the  perineum.  Many  cases  of  sudden  death  from  embolism  are  preceded  by  mild 
febrile  symptoms,  rapid  pulse,  or  local  symptoms  which  indicate  that  disease  of  some 
kind  exists  in  the  pelvis.  Excepting  these  accidents,  the  course  of  the  thrombosis  is 
not  alarming;  the  fever  keeps  a  low  level,  the  general  health  is  good,  appetite  and 
sleep  are  but  little  disturbed,  and  recovery  takes  place  in  from  two  to  six  weeks. 
The  disease  usuallj^  begins  after  the  eighth  day  of  the  puerperium,  and  is  caused  by 
an  organism  of  low  virulence — either  an  attenuated  streptococcus  or  the  staphjdo- 
coccus,  even  sometimes  by  the  bacteria  which  normally  grow  as  saprophytes  in  the 
genitals.     This  form  of  phlegmasia  occurs  not  seldom  after  myoma  operations. 

(2)  Thrombophlebitis  of  the  pelvic  and  crural  veins  may  be  the  outward  exten- 
sion of  the  infected  uterine  veins,  being  only  a  part  of  a  pyemic  process,  to  which  ref- 
erence has  already  been  made,  and  it  may  also  occur  apparently  alone.  In  the  former 
case  the  symptoms  and  signs  of  endometritis  or  pelvic  inflammation  precede  the  pain 
and  swelling  of  the  leg;  in  the  latter  case  the  initial  chill  is  followed  at  once  by  the 
localization  in  the  extremity.  Often  the  intrapelvic  symptoms  of  the  early  puer- 
perium are  overlooked.  Usually  after  the  eighth  day,  and  perhaps  as  late  as  the 
twentieth,  the  puerpera  experiences  pain  in  the  groin,  aiid  at  the  same  time  in  the 
calf  of  the  leg.  The  pain  is  so  great  that  the  leg  is  immovable.  The  swelling  is 
noticed  first  in  Scarpa's  triangle  and  in  the  labium  vulvae  of  the  affected  side.  The 
groin  is  the  site  of  the  greatest  pain,  and  sometimes  it  is  possible  to  feel  the  throm- 
bosed veins  under  Poupart's  ligament.  The  upper  thigh  is  sometimes  swollen  to 
twice  its  natural  size,  has  a  white,  opalescent,  or  somewhat  yellowish  tint,  feels  hot 
to  the  touch,  is  exceedingly  sensitive,  and  pits  with  difficulty  on  pressure.  AVithin 
a  few  hours  or  days  the  whole  limb  is  involved,  but  sometimes  the  lower  leg  and  foot 
seem  rather  to  be  edematous,  and  not  infiltrated  with  haiiph.  W.  A.  Freund  has 
differentiated  In'  puncture  the  lymph  of  the  upper  thigh  from  the  serum  of  the  lower 
leg.  The  milk-white  appearance  of  the  limb  gave  the  disease  the  popular  appella- 
tion, "milk-leg" — indeed,  the  ancients  believed  it  was,  in  reality,  a  milk  metastasis. 

At  the  beginning  a  chill  may  or  may  not  occur,  but  fever  is  always  present,  to- 
gether Anth  the  symptoms  of  severe  illness — i.  e.,  of  infection,  of  a  pyemic  process. 
Both  limbs  may  be  involved  at  once  or  one  after  the  other.  The  fever  pursues  an  ir- 
regular course,  with  marked  remissions;  the  pulse  is  usually  high,  and  the  course  of 
the  disease  is  ver}' protracted,  especially  if  one  limb  is  involved  after  the  other.  Weeks 
or  months  may  elapse  before  the  signs  of  inflammation  and  obstruction  of  the  veins 
disappear,  and  the  general  health  may  suffer  very  much.  Bed-sores  are  prone  to 
form  over  the  sacrum  and  the  heels.  E^'en  long  after  the  recovery  edema  of  the 
foot  will  appear  when  the  patient  is  much  on  her  feet.  In  bad  cases  the  inflamma- 
tion passes  over  to  the  arteries;   thrombosis  occurs  here  too,  and  gangrene  of  the 


860  PATHOLOGY    OF    THE    PUERPERIUM 

extremity  results.  If  many  of  tlie  veins  of  the  leg  become  occluded,  the  circulation 
may  l)e  stopjx^il,  with  the  same  result.  Arterial  thrombosis  may  also  result  from 
emboli  from  the  valves — endocarditis.  Immediate^  am}:)utation  is  demanded  when 
the  diagnosis  of  gangrene  is  made;  delay  means  death,  and  even  amputation  may 
not  save.  Portions  of  the  calves  and  thighs  may  slough  off  from  pressure  and  poor 
circulation.     Treatment  is  based  on  surgical  principles. 

Pathologically,  in  these  cases  one  finds  the  pelvic  veins  full  of  firm  throml)i, 
and  the  inflammation  has  crept  out  through  the  i^ampiniform  plexus  to  the  obturator 
vein,  or  even  through  the  hj'pogastric,  to  the  common  iliac,  and  then  backward  to 
the  femoral.  In  addition  to  the  endophlebitis  and  phlebitis,  there  is  a  marked  peri- 
phlel^itis.  The  connective  tissue  around  the  veins  is  infiltrated  with  a  gelatinous, 
mucoid  material  ("phlegma"),  and  the  lymphatics  which  accompany  the  veins  are 
filled  and  occluded  by  the  same  material.  Whether  or  not  there  is  a  lymphangitis 
or  simply  a  lymphatic  stasis  with  coagulation  of  the  lymph  has  not  been  settled — 
probably  both  exist.  This  Ijonphatic  process  accompanies  the  inflammation  of  the 
veins  as  the  latter  spreads  out  of  the  pelvis  and  down  the  leg.  Incision  into  such 
a  leg  shows  the  cellular  tissue  solid  with  coagulated  l^'mph — the  same  in  the  lym- 
phatics. The  large  veins  are  filled  with  thrombi,  partly  solid,  partly  puriform  de- 
generated. The  phlebitis  may  be  primary,  or  secondarj^  to  a  pelvic  cellulitis,  and 
the  process  may  be  reversed;  a  phlebitis  may  lead  to  a  cellulitis,  and,  owing  to  the 
proximity  of  the  peritoneum,  to  a  local  peritonitis.  The  clinical  picture  maj^  then 
be  indistinct,  combining  symptoms  and  signs  of  the  three  conditions. 

(3)  Pelveocrural  Cellulitis. — In  this  form  of  phlegmasia  the  condition  is  one  of 
extension  of  a  cellulitis  from  the  pelvis.  This  cellulitis  differs  from  the  form  de- 
scribed under  Parametritis  in  the  rapidity  of  its  spread,  its  tendency  to  attack  the 
subcutaneous  cellular  tissue,  the  lateness  of  suppuration,  if  at  all,  and  the  severity  of 
its  effect  on  the  general  sj^stem.  It  resembles  the  malignant  infections  of  the  arm, 
and  is,  like  them,  almost  always  caused  by  a  virulent  strain  of  streptococci.  The 
infection  may  leave  the  pelvis  either  above  or  below,  and  the  resulting  inflammation 
of  the  upper  thigh  will  appear  first  over  Poupart's  ligament  or  in  the  nates.  Swell- 
ing, pain,  heat,  and  redness  characterize  this  form  of  phlegmasia,  and  it  often  is  but 
part  of  a  general  septicemia.  Very  often,  in  addition,  thrombosis  occurs  in  the 
crural  veins,  and  then  the  lower  part  of  the  affected  extremity  swells  up  with  edema, 
and  the  picture  resembles  the  ordinary  phlegmasia  alba  dolens  more.  It  may  at 
first  be  difficult  to  distinguish  between  the  two  forms,  but  the  fact  that  the  inflamma- 
tion with  the  swelling  began  in  the  upper  part  of  the  thigh  first  and  the  edema  of  the 
foot  came  a  considerable  time  later, — an  observation  clearly  made  by  Levret  in 
1766, — and  the  demonstration  of  a  pelvic  cellulitis,  will  aid  a  good  deal  in  the  differ- 
entiation. Blisters  and  pustules  occur  with  l)oth  forms.  Necrosis  and  abscess  are 
rare  with  the  purely  phlebitic  phlegmasia,  and  commoner  with  the  cellulitis.  The 
course  of  this  kind  of  phlegmasia  is  rapid  and  usually  fatal,  the  inflammation 
involving  both  limbs,  and  the  bacteremia  being  pronounced.  If  healing  is  to 
take  place,  the  infection  ceases  to  spread  and  the  general  symptoms  ameliorate. 
Abscess  formation  is  a  favorable  sign  unless  the  whole  limb  l)ecomes  studded  with 
areas  of  necrosis.  Such  cases  are  protracted  and  serious.  The  diagnosis  is  easy, 
as  a  rule.  Sometimes  it  may  be  necessary  to  shut  out  neuritis  or  parametritis, 
when  the  thrombosis  is  deep  seated  and  edema  not  yet  Ix-gun. 

Treatment. — Prevention.  Extreme  asepsis  in  the  conduct  of  all  ()l)stetric  cases 
will  effectually  prevent  the  vast  majority  of  all  the  forms  of  phlegmasia  ali)a  dolens. 
The  milder  thromljoses,  phlegmasia  of  the  t^'pe  first  described,  may  now  and  again 
occur  with  faultless  technic,  but  these  are  also  ascribable  to  infection,  probably 
endogenous  in  origin,  though  many  authors  believe  they  are  due  to  stasis  of  the 
blood  in  the  veins,  prolonged  rest  in  the  horizontal  position,  and  alteration  of  the 
blood.     To   forestall   such   thromboses  many   authors,    especially   the    (iermans, 


CLINICAL   TYPES    OF    PUERPERAL   INFECTION  861 

recommend  that  the  puerpera  l)e  gotten  out  of  bed  as  soon  as  possible  after  labor — 
on  the  second  or  third  day.  This  is  said  to  improve  the  circulation  and  prevent 
thrombi  from  forming.  I  am  not  strongly  in  sympathy  with  such  a  practice,  but 
give  the  puerpera  much  more  freedom  in  bed  than  formerly.  (See  Time  of  Getting 
Up,  p.  326.) 

Aside  from  the  general  rules  applical)le  to  all  forms  of  puerperal  infection,  which 
will  be  discussed  later,  the  treatment  of  phlebitis  and  thrombosis  requires  special 
precautions.  The  dangers  are  embolism  and  bed-sores.  Good  nursing  is  of  prime 
importance.  Moving  the  patient  and  the  affected  limb  is  restricted  to  a  minimum, 
and  is  done  slowly  and  with  the  greatest  care.  In  addition  to  the  cradle  sho"s\'n  in 
Fig.  761,  a  symphysiotomy  bed  (Fig.  815)  may  lx»  employed.  The  limb  is  to  be 
elevated  slightly  to  aid  the  return  circulation,  which  may  be  done  as  in  Fig.  761, 
or  by  means  of  a  few  pillows.  For  a  few  hours  each  day  the  leg  should  lie  flat,  the 
change  being  made  guardedly.  The  pad  to  protect  the  heel  is  to  be  placed  under 
the  tendo  Achillis,  and  the  bed-clothes  are  to  be  supported  by  a  cradle  of  hoops  or 
by  the  top  of  the  box  shown  in  the  illustration.     Drop-foot  may  be  prevented 


Fig.  761. — Phlegm.\si.\  Cradle. 
Adhesive  strap  is  to  support  the  ball  of  the  foot     The  board  is  well  padded. 

by  an  adhesive  strap  running  from  the  sole  or  the  big  toe  to  the  side  of  the 
box.  The  padding  in  the  box  is  best  made  of  eiderdown,  and  is  to  be  fre- 
quently aired,  and  changed  whenever  soiled.  After  from  four  to  eight  weeks  the 
clot  may  be  considered  firm  enough,  and  the  patient  given  a  little  more  freedom, 
but  it  is  best  to  keep  her  in  bed  for  at  least  two  weeks  after  the  temperature  has  be- 
come normal.  Massage  of  the  limb  is  not  permitted  for  several  months  after  the 
patient  is  about.  I  never  use  ointments,  bandaging,  or  aiijilications  of  wet  dressings 
to  the  liml) — the}'  disturb  the  parts  too  much.  At  most,  when  there  is  great  pain 
in  the  groin,  a  light  ice-bag  or  a  warm-water  bag  is  applied.  Care  is  required  to 
avoid  freezing  and  burning,  both  of  which  are  more  likely  to  occur  when  the  circu- 
lation is  poor.  Mori)hin  may  he  used  for  pain.  It  is  important  to  keep  up  the 
nourishment.  Later,  when  the  patient  gets  up,  the  foot  may  become  edematous. 
A  rubber  stocking  may  sometimes  be  worn  Anth  comfort.  In  a  subsequent  puer- 
perium  the  thrombosis  may  recur.  In  the  event  of  pulmonary  embolism  the  at- 
tendant is  powerless.  Trendelenburg  and  others  have  opened  the  pulmonary  artery 
and  removed  the  clots,  but  all  the  patients  have  died.  One  died  five  days  later  from 
infection  of  the  wound,  and  thus,  perhaps,  might  have  been  saved. 


862  PATHOLOGY  OF  THE  PUERPERIUM 

Intramural  Uterine  Abscess. — ]\Iorc  commonly  than  is  reported,  a  uterine 
lymphangitis  or  phlel)itis  results  in  an  abscess  within  the  muscular  wall.  Such 
abscesses  may  be  single  or  multii:)le,  seem  to  prefer  the  cornua  as  sites,  and  may  be 
the  only  local  cause  for  the  general  symptoms,  or  may  be  only  a  part  of  an  extensive 
local  infectious  process,  as  pelvic  peritonitis,  cellulitis,  pyosalpinx,  phle])itis.  These 
abscesses  may  break  into  neighboring  organs — the  bladder,  the  peritoneum,  the 
parametrium,  the  sigmoid,  or  the  rectum;  they  may  break  into  the  cavity  of  the 
uterus,  giving  rise  to  a  sudden  discharge  of  pus  per  vaginam,  which  simulates  that 
of  a  pyosalpinx,  or  they  may  be  absorbed  or  inspissated.  The  course  of  the  uterine 
abscess  is  chronic.  The  symptoms  of  the  acute  stage  of  the  infection  subside,  and 
the  accoucheur's  attention  is  drawn  to  this  condition  by  the  persistence  of  the  fever, 
etc.  Examination  shows  the  uterus  enlarged,  and,  at  some  point,  a  soft,  fluctuating 
tumor  is  palpable.  In  my  own  case  the  abscess  was  felt  in  the  right  uterine  cornu 
posteriorly,  through  an  incision  made  to  evacuate  pus  in  the  culdesac.  The  patient 
recovered,  the  abscess  either  draining  spontaneously  or  having  become  quiescent, 
and  she  has  been  sterile  since.  A  soft  or  suppurating  fibroid  will  give  all  the  symp- 
toms and  signs  of  uterine  abscess.  An  exploratory  laparotomy  may  be  necessary  to 
confirm  the  diagnosis.  Treatment  is  surgical.  If  the  symptoms  persist,  the  abscess 
is  attacked  by  laparotomy,  but  drained  if  possiljle  from  below,  otherAvise  from  above, 
walling  off  the  general  peritoneal  cavity  with  gauze  and  by  fixing  the  omentum  to 
the  uterus.  A  drainage-tube  may  be  inserted  into  the  abscess  and  led  out  of  the 
belly,  l)eing  fastened  in  place  with  sutures  (Barrows).  If  the  uterus  is  riddled  with 
abscesses,  hysterectomy  and  free  vaginal  drainage  are  indicated. 

Specific  Infections. — Gonorrhea. — A  large  number — easily  15  per  cent. — of  the 
patients  of  our  public  maternities  enter  with  a  latent  gonorrhea.  In  private  prac- 
tice the  number  will  perhaps  not  exceed  10  per  cent.  Since,  with  modern  aseptic 
methods,  fever  is  becoming  so  rare,  we  conclude  that  the  gonococcus  does  not  play 
a  very  important  role  in  puerperal  infection.  Acute  gonorrhea  is  much  more  likely 
to  spread  than  the  chronic  and  to  become  serious,  both  as  regards  the  mother  and 
also  the  baby,  its  eyes,  navel,  etc.  When  the  disease  is  latent,  the  surfaces  are 
usually  free  from  the  organisms,  the  gonococci  resting  in  the  crypts  of  the  vulva,  the 
urethra,  Skene's  tubules,  the  ducts  of  Bartholin's  glands,  and  sometimes  the  cervical 
glands.  If  the  tubes  are  already  infected,  temporary  or  permanent  sterility  results. 
Causes  which  we  do  not  understand  effect  an  increase  of  virulence  of  these  cocci; 
then  they  spread  all  over  the  surface  of  the  parts,  even  to  the  uterine  cavity,  up 
through  and  out  of  the  tubes  onto  the  pelvic  peritoneum  and  ovaries,  causing  pyo- 
salpinx, ovarian  abscess,  and  pelvic  peritonitis.  This  extension  on  the  surface  is 
the  rule  with  gonorrhea,  but  in  exceptional  cases  the  bacteria  burrow  into  the 
cellular  tissue,  causing  cellulitis,  with  or  without  abscess,  or  into  the  veins,  causing 
phlebitis,  phlegmasia,  metastases,  gonitis,  endocarditis,  even  general  bacteremia — 
gonococcemia.  It  is  usual  to  find  a  mixed  infection  in  these  conditions,  but  there 
is  no  doubt  but  that  the  gonococcus  alone  can  cause  them. 

Symptoms. — There  is  nothing  characteristic  about  gonorrheal  infections.  Usu- 
ally the  fever  begins  later  in  the  puerperium  than  the  other  infections,  because  it 
requires  some  time  for  the  cocci  to  attain  full  virulence  and  to  pass  up  through  the 
uterus  to  the  tubes  and  peritoneum.  Pelvic  peritonitis  l:)eginning  after  the  seventh 
day  is  almost  always  gonorrheal.  Involvement  of  a  single  joint,— the  knee  or  the 
wrist, — of  a  very  chronic  nature,  is  often  gonorrheal;  indeed,  pregnancy  and  the 
puerperium  are  the  most  potent  predisposing  causes  of  gonorrheal  "rheumatism." 
With  the  rare  exceptions  mentioned  the  symptoms  are  mild,  and  apply  to  the  part 
of  the  pelvic  anatomy  which  is  affected.  The  course  of  the  cases  is  usually  pro- 
tracted, which  is  especially  true  of  pyosalpinges  and  ovarian  abscesses.  A  collec- 
tion of  pus  in  the  culdesac  may  be  opened  when  it  bulges  toward  the  vagina  or  the 
rectum,  and  healing  is  then  rapid.     Deforming  scars  and  adhesions  always  follow 


CLINICAL   TYPES    OF   PUERPERAL   INFECTION  863 

gonococcal  infections,  and  sterility  is  the  usual  result.  The  diagnosis  may  seldom 
be  made  from  the  clinical  course.  The  finding  of  the  gonococcus  in  large  numbers 
(rarely  in  pure  culture)  in  the  lochia  will  indicate  the  cause  of  the  symptoms,  but 
not  positively,  because  the  streptococcus,  the  pyococcus,  or  the  Bacterium  coli  in 
symbiosis  may  be  at  the  root  of  the  real  illness.  The  prognosis  as  to  life  is  good,  as 
to  health,  dubious.  The  women  almost  never  fully  recover  if  the  infection  passes 
beyond  the  uterus.  After  many  years  the  tubes  may  become  patulous,  and  even 
pregnancy  supervene,  but,  as  a  rule,  the  women  remain  their  life  long  gynecologic 
invalids  and  often  require  capital  operations  to  restore  even  partial  health. 

Treatment  is  based  on  general  principles.  Local  treatment  is  absolutely  con- 
traindicated  in  the  acute  stage.  Prolonged  rest  in  bed  is  imperative.  Only  after 
the  fever  has  been  absent  a  week  may  the  puerpera  get  up.  If  an  internal  examina- 
tion is  to  be  made,  it  is  done  very  gentl3^  If  an  abscess  is  felt  in  the  culdesac,  it  is 
to  be  opened,  but  not  before  the  surrounding  adhesions  are  very  firm.  The  tubular 
drain  may  be  removed  when  the  discharge  has  nearly  ceased — usually  at  the  end  of 
ten  days;  then  a  l^it  of  gauze  is  kept  in  the  vaginal  opening  for  a  few  days.  Irriga- 
tions of  the  pus-sac  are  never  made.  Pyosalpinges  should  not  be  removed,  either 
vaginally  or  abdominally,  for  a  year  at  least,  and  even  then  only  for  specially  in- 
sistent indications.  If  the  pyosalpinx  is  due  to  a  streptococcous  infection,  several 
years  may  elapse  before  its  removal  is  positively  safe. 

Tetanus. — Nowadays  tetanus  is  the  rarest  of  all  infections  in  the  puerperium,  but  when 
it  does  occur,  it  is  of  a  most  virulent  type.  Pathology,  symptoms,  diagnosis,  and  treatment  do 
not  differ  from  those  of  surgical  tetanus.  Prophylaxis  in  maternities  recjuires  special  severity,  be- 
cause, to  judge  from  the  experience  of  one  European  hospital,  when  the  disease  is  once  introduced, 
all  ordinary  means  of  eradicating  it  may  fail.  If,  therefore,  one  case  should  occur  in  a  lying-in 
hospital,  the  patient  had  better  be  removed  at  once  from  this  institution,  and  all  the  rooms  she 
occupied  be  disinfected  in  the  most  thorough  manner  and  left  exposed  to  the  elements  for  at  least 
a  week.  All  instruments  and  utensils  that  came  in  contact  with  the  patient  should  be  doubly 
sterilized,  and  all  the  women  exposed  to  the  infection  given  an  immunizing  dose  of  antitoxin. 

Diphtheria. — This  is  rare  in  the  puerperium,  and  the  disease  differs  in  no  way,  except  local- 
ization, from  that  observed  in  the  throat.  The  membrane,  unlike  that  of  the  streptococcus,  shows 
a  marked  tendency  to  spread  all  over  the  parturient  canal,  and  usually  leaves  no  scars.  General 
symptoms  of  toxinemia  are  in  evidence,  and  if  the  streptococcus  is  associated,  a  severe  septi- 
cemia may  ensue.  Over  40  cases  of  puerperal  diphtheria  are  on  record.  I  had  one.  Siricars  and 
cultures  should  be  taken  from  every  puerperal  fever  case  in  order  to  discover  diphtheria.  Treat- 
ment with  antitoxin  in  maximal  doses  is  indicated,  but  no  local  treatment  at  all.

CHAPTER  LXV 
DIAGNOSIS  OF  PUERPERAL  INFECTION 

Most  cases  of  fever  in  child-bed  are  cases  of  child-bed  fever,  ])ut  this  fact  must 
not  lead  the  accoucheur  into  carelessness  in  his  treatment  of  feverish  puerperae. 
Several  times  I  have  found  the  attendant  giving  intra-uterine  douches  when  the 
patient  was  suffering  from  tonsillitis.  In  my  owti  experience  the  following  diseases 
have  been  mistaken  for  puerperal  infection:  typhoid  fever,  acute  miliary  tubercu- 
losis, meningitis,  acute  j^ellow  atrophy  of  the  liver,  tonsillitis,  pneumonia,  la  grippe, 
tubercular  peritonitis,  appendicitis,  cholecystitis,  ureteropyelitis,  and  mastitis.  In 
practice,  therefore,  while  puerperal  infection  is  the  first  to  be  thought  of  when  the 
puerpera  sickens,  the  patient  should  be  subjected  to  a  complete  and  careful  physical 
examination,  and,  b}'  a  process  of  exclusion,  the  diagnosis  reached  that  the  disease  has 
taken  its  origin  in  the  genitals.  It  is  wise  to  repeat  the  general  examination  at  in- 
tervals of  three  or  four  days  to  avoid  surprises,  and  early  to  recognize  complications. 

After  it  is  certain  that  the  case  is  one  of  infection,  these  questions  are  to  be 
answered,  all  being  essential  to  prognosis  and  treatment:  (1)  What  is  the  anatomic 
location  of  the  infection?  (2)  In  what  direction  is  it  spreading  and  how  far?  (3) 
Is  the  infection  more  general  than  local,  or  more  local  than  general?  (4)  What 
bacterium  is  causative?     (5)  Is  there  an\i;hing  in  the  uterus? 

Ad  1 :  A  study  of  the  history  of  the  labor  may  indicate  at  once  the  site  of  the 
infection,  for  example,  if  the  delivery  was  instrumental,  with  extensive  injury  to  the 
cervix,  the  usual  result  of  infection  is  a  cervicitis  followed  by  parametritis  or  peri- 
tonitis. Perineorrhaphies  may  suppurate.  jManual  removal  of  the  placenta  is 
often  followed  by  endometritis  and  bacteremia,  curetage  postpartum  by  bacteremia 
via  the  lymphatics,  with  or  without  peritonitis,  and  so  on.  In  addition  to  the 
history  the  site  of  pain  and  other  local  symptoms  may  point  to  the  anatomic  struc- 
ture involved.  Early  in  the  puerperium  it  is  dangerous  to  make  an  internal  ex- 
amination, and,  further,  the  information  gained  is  slight.  Specular  examinations 
are  not  recommended.  All  these  manipulations  tear  open  the  puerperal  wounds, 
reinoculate  the  tissues,  and  carry  the  infection  to  parts  higher  in  the  parturient  canal. 
Inspection  of  the  vulva,  aided  by  separating  the  labia  to  get  a  good  view  of  the 
introitus,  will  give  useful  information,  the  condition  of  the  puerperal  wounds  being 
a  good  index  of  what  is  going  on  higher  up.  (See  Endometritis.)  Parametritis 
and  pelvic  peritonitis  are  usually  easily  distinguishable^ — if  not  at  first,  then  later 
in  their  course. 

Ad  2:  Ordinarily  the  spread  of  the  infection  can  be  traced  from  day  to  day  by 
the  clinical  course  of  the  disease.  jNIetastases  in  various  parts  of  the  body  give 
symptoms  characteristic  to  the  part  affected. 

Ad  3 :  The  determination  whether  the  infection  is  limited  to  the  uterus  or  has 
already  invaded  the  blood  is  not  easy — indeed,  as  was  already  stated,  Schottmiiller 
has  proved  that  in  many  cases,  formerly  considerc^d  local  diseases,  that  is,  toxinemic 
only,  a  hemolytic  anaerobic  streptococcus  may  Ix'  cultivated  from  the  blood.  For- 
merly sterility  of  the  blood  was  considered  evidence  that  the  infectious  process  was 
entirely  local.  Now,  unless  anaerobic,  as  well  as  aerobic,  methods  and  the  utmost 
variety  of  culture-media  are  used,  sterility  of  the  blood  may  not  be  regarded  as 
evidence  that  the  bacteria  are  restricted  to  the  genitals.  In  many  cases  the  strep- 
tococcus has  been  found  culturally  in  the  blood,  the  staphylococcus  also,  as  well  as 

864

865 


other  bacteria  previously  inontioned,  and  when  they  are  found  easily,  by  the  or- 
dinary methods  or  in  large  numbers,  one  may  conclude  that  a  bacteremia  exists. 
For  the  technic  of  the  bacteriologic  study  of  the  blood  the  reader  is  referred  to  ap- 
propriate text-books.  Clinically,  the  accoucheur  may  not  ])e  able  positivelj'  to 
decide  from  the  symptoms  whether  he  has  a  purely  local  infection  with  toxinemia,  or 
whether  the  blood  is  also  being  disorganized  by  the  bacteria,  but  in  general  the 
severity  of  the  illness  is  a  fair  guide.  Continuous  high  temperature,  very  rapid 
pulse,  severe  prostration,  etc.,  point  to  bacteremia. 

Ad  4:  It  is  usually  possible  to  determine  what  germ  is  causative — at  least  the 
one  taking  the  leading  role.  Investigation  has  shown  that  the  streptococcus  pyo- 
genes is  the  commonest,  and  since  some  of  its  strains  are  very  virulent  and  others 
less  so,  it  is  needful  to  discover  which  one  is  active  in  the  particular  case.  Un- 
fortunately, we  are  not  able  to  do  this.  Tests  of  the  virulence  of  cultures  of  strepto- 
cocci on  the  lower  animals  are  unreliable  because  the  latter  do  not  react  as  do  the 
humans.  Long  chains  of  streptococci  do  not  indicate  high  virulence,  l)ut  onh'  that 
the  culture-medium  is  favorable  to  such  groAA-th.  Hemolysis  in  cultures  (on  blood- 
agar,  for  example)  has  been  proved  to  occur  with  many  kinds  of  streptococci,  though 
it  almost  always  betokens  a  virulent  strain,  and,  on  the  other  hand,  anhemolytic

streptococci  may  be  very  virulent  (Zangemeister) .  Fromme's  lecithin-bouillon 
test  also  has  proved  fallacious,  and  thus  the  work  of  Schottmiiller,  ]\Iau,  and  Zange- 
meister has  borne  httle  fruit.  In  order  to  find  out  the  causative  bacteria  it  is 
necessary  to  make  exhaustive  studies  of  the  blood,  as  well  as  of  the  lochia.  A  small 
quantity  of  the  lochia  is  obtained  from  the  deeper  portion  of  the  vagina  by  means  of 
a  simple  pipet,  and  cultures  made  in  all  the  Ioioaati  bacteriologic  media,  both  anae- 
robic as  well  as  aerobic  (Fig.  762).  Smears  are  also  examined.  The  best  stain  is 
Loffler's  methylene-blue. 

Just  because  one  identifies  certain  bacteria  in  the  lochia  does  not  permit  the 
deduction  that  the  infection  results  from  that  particular  organism.  If  it  is  found  in 
large  numl)ers,  in  pure  culture,  or  overshadowing  all  the  others,  the  conclusion  that 
it  is  causative  may  be  hazartled,  and  if,  in  addition,  the  same  organism  is  fountl  in 
the  blood,  the  diagnosis  becomes  positive.  Regarding  the  streptococcus,  Krcinig 
believes  that  this  simple  test  will  enable  one  to  be  positive.  If  a  small  amount  of 
lochia,  inoculated  on  blood-agar,  gives  rise  to  very  numerous  hemol^-tic  colonies, 
the  puerpera  is  suffering  from  puerperal  infection.  If  a  finer  reagent  is  used,  such 
as  grape-sugar  bouillon,  streptococci  will  grow  in  80  per  cent,  of  even  normal  puer- 
perae,  and  the  test  is  less  valuable. 
55 


866 


PATHOLOGY    OF   THE   PUERPERIUM 


The  gonoc'occus  is  easy  to  recognize  in  the  lochia,  and  when  present  in  large 
nunilx^rs  or  ]:>ure  culture,  may  be  held  responsible  for  the  clinical  picture.  Still,  the 
accoucheur  must  bear  in  mind  that  the  gonococcus  is  frequently  associated  with  the 
streptococcus  and  the  stai)hyl()coccus,  and  that  all,  or  at  least  a  goodly  part  of,  the 
disease  may  be  due  to  the  latter.  Further,  gonococci  may  appear  in  the  lochia  of  an 
apparently  healthy  puerpera,  and  their  presence  may  be  proved  by  clinical  experi- 
ence— i.  €.,  gonorrheal  ophthalmia  neonatorum,  the  mother  remaining  well.  The 
discovery  of  true  tetanus  bacilli  has  not  yet  been  made  except  in  tetanus.  In  one 
case  seen  by  the  writer  in  consultation  diphtheria  Imcilli  were  ol)tained  by  a  com- 
petent bacteriologist  when  neither  the  appearance  of  the  genitals  nor  the  clinical 
course  suggested  diphtheria.  In  the  differential  diagnosis  of  puerperal  infections 
from  other  diseases  accompanied  by  fever  the  bacteriologic  investigation  of  the

cells

Streptococcus  Infection. 


lochia  gives  only  conditional  information.  For  example,  if  the  diagnosis  lies  be- 
tween miliary  tuberculosis  and  sepsis,  the  finding  of  streptococci  in  the  lochia  would 
not  be  enough  to  fix  the  diagnosis  of  sepsis.  Much  more  information  would  be 
gotten  from  the  V:)loo(l  examination.  Here  the  streptococcus,  the  finding  of  the 
tubercle  bacillus,  the  typhoid  bacillus,  and  the  pneumococcus  give  us  dependable 
information. 

Having  pursued  the  investigation  of  the  case  along  the  four  lines  indicated,  the 
accoucheur  may  usually  make  a  satisfactory  diagnosis.  In  actual  practice  other 
questions  arise.  One  of  the  most  conmion  is — (5)  "  Is  there  anything  in  the  uterus?" 
This  has  been  discussed  on  p.  839.  If  the  answer  cannot  be  positively  made,  the 
case  is  treated  as  if  there  were  nothing  in  the  uterus — contrary  to  older  teachings. 
Another  duty  of  the  attendant  is  the  diagnosis  of  the  condition  of  the  vital  organs  of 


DIAGNOSIS   OF   PUERPERAL   INFECTION 


867 


the  bod}^,  the  state  of  the  liver,  of  the  kidneys,  of  the  lungs,  of  the  heart,  of  the 
blood — these  must  all  be  watched  to  discover  how  they  are  withstanding  the  attack 
of  the  toxins  and  bacteria. 

If  the  case  becomes  chronic,  an  internal  examination  is  to  be  made  to  find  any- 
localized  suppuration,  as  pelveocellulitic  abscess,  perimetritic  exudates,  pyosalpinx, 
ovarian  abscess,  intramural  uterine  abscess,  infected  myoma,  etc. 

A  word  of  caution  may  be  permitted  here.  In  all  infected  cases  the  utmost 
gentleness  is  to  be  practised  in  palpating  the  pelvic  structures.  Only  too  easily  is 
the  infectious  process  carried  into  regions  hitherto  protected,  and  also  a  collection  of 
pus  may  be  broken  into  the  general  peritoneal  cavity,  which  usually  results  fatally, 
in  spite  of  immediate  laparotomy  and  free  drainage  above  and  Ix'low. 

The  differential  diagnosis  should  consider — (1)  All  the  pelvic  infiammations, 


Fio.  764. — Lochia — Saprophytic  Infection. 


one  from  the  other,  and  from  inflamed  tumors  (myomata,  cysts,  etc.) ;  (2)  the  separa- 
tion of  pelvic  infections  from  those  of  the  urinary  system,  especially  ureteropyelitis; 
(3)  the  differentiation  from  inflammations  of  other  organs  in  the  belly,  e.  g.,  the 
gall-bladder,  the  appendix;  and  (4)  from  all  general  diseases — typhoid,  malaria, 
tuberculosis,  etc.  Obviously,  in  a  treatise  of  this  size  a  presentment  of  all  these 
subjects  is  impossible.     Apjiroi^riate  text-books  must  be  consulted. 

In  considering  pyrexia  during  the  puerperium,  mention  must  be  made  of 
"nervous"  temperature.  Many  accoucheurs  and  nearly  all  nurses  believe  that  a 
puerpera  may  develop  fever  from  nervous  shock  or  excitement,  but  such  an  oc- 
currence has  never  come  under  my  personal  observation.  In  the  dispensary  ser\'ice 
of  the  Chicago  L>ing-in  Hospital  a  woman  on  the  fifth  day  after  delivery,  as  the 
result  of  anger  against  her  husband  who  drank  up  their  small  store  of  money,  and 


868 


PATHOLOGY    OF   THE    PUERPERIUM 


anxiety  for  lier  children,  who  were  without  food,  became  intensely  wrought  up  and 
developed  a  teni])crature  of  10")°  F.  The  nurse  ])rought  food  for  her  and  her  chil- 
dren, and  the  fever  sul)sided  within  six  hours.  No  other  cause  was  demonstrable. 
Granting  this  possibility,  it  must,  however,  be  emphasized  that  pyrexia  from  ner- 
vousness is  of  greatest  rarity.     Infection  is  almost  always  the  actual  cause. 

Prognosis  of  Puerperal  Infection. — Statistics,  usually  deceptive,  are  particularly 
fallacious  in  puerperal  infection.  The  disease  is  so  protean  in  its  manifestations 
that  it  is  next  to  impossible  to  group  cases  similar  enough  to  make  general  deduc- 
tions from — to  say  nothing  of  reducing  them  to  figures.  Experience,  however,  will 
permit  the  attendant  to  give  a  good  or  a  bad  prognosis,  and  if  he  has  made  a  com- 
plete diagnosis,  as  outlined  in  the  previous  section,  much  difficulty  will  l)e  overcome. 

Infection  varies  in  gravity  with  the  anatomic  part  involved,  the  direction  of  its 


Fig.  705. — Lochia — Gonorrheal  Infection. 


spread,  the  degree  of  invasion  of  the  blood,  and  the  nature  of  the  infecting  organism. 
Vulvitis  and  vaginitis  are  usually  not  serious — only  rarely  does  the  infection  break 
through  the  natural  barriers  and  get  into  the  blood  or  travel  up  to  the  peritoneum, 
and  this,  with  the  Streptococcus  pyogenes.  Endometritis  is  more  dangerous, 
but  here,  too,  the  larg(^  majority  of  cases  recover,  although  the  strepto(;occus 
may  be  causative,  unless  improper  treatment  is  instituted.  Putrid  endometritis, 
even  when  there  is  consideraljle  decaying  material,  heals  rapidly  if  drainage  is  good. 
Lochiometra,  responsible  for  many  "one-day  fevers,"  is  easily  relieved  by  treat- 
ment and  almost  invarial)ly  has  a  good  prognosis.  Parametritis,  with  the  exception 
of  the  form  called  erysipelas  internum  puerperale,  which  is  really  Init  a  part  of  a 
septicemia,  has  a  good  prognosis.  Even  if  the  whole  connective-tissue  framework 
of  the  pelvis  is  involved,  the  prognosis  is  good  as  to  life,  because  if  an  abscess  does 


DIAGNOSIS    OF    PUERPERAL    INFECTION  869 

not  form,  nature  usually  absorbs  the  exudates,  and,  further,  the  bacteria  involved 
are  rarely  of  a  virulent  type.  Perimetritis  is  more  serious,  because  at  the  start  one 
cannot  say  if  the  disease  will  remain  limited  to  the  pelvis.  If  the  clinical  evidence 
early  in  the  disease  seems  to  indicate  such  limitatic^n,  the  prognosis  is  good  and  re- 
covery is  the  rule,  since  the  bacteria  are  not  likely  to  be  virulent  (often  the  gono- 
coccus)  and  the  resistance  of  the  woman  is  shown  to  be  strong.  General  periton- 
itis is  almost  always  fatal.  Very  few  cases  of  streptococcus  infection  recover,  but 
even  here  hope  should  be  by  no  means  abandoned.  Bacteremia  or  general  septicemia 
is,  in  three-quarters  of  the  cases,  fatal.  Septicopyemia  or  metastatic  bacteremia 
isliot  so  dangerous.  Bumm  complains  of  a  high  mortality,- — 80  per  cent.,- — but  my 
own  experience  has  been  more  favorable — almost  30  per  cent.  These  forms  of  inflam- 
mation show  that  nature  is  more  or  less  successful  in  localizing  the  infection.  Indeed, 
in  all  cases  where  the  accoucheur  detects  a  tendency  at  limitation  a  good  prognosis 
may  be  given.  Spreading  infections  and  invasion  of  the  blood-stream  and  of  the 
peritoneal  cavity  are  always  serious.  Phlegmasia  alba  dolens  is  usually  a  favorable 
outcome  of  a  puerperal  infection.  The  large  majority  of  cases  recover,  unless  it  be 
the  form  of  crural  cellulitis,  which  is  often  fatal. 

Much  depends  on  the  causative  organism.  Tetanus  is  the  most  fatal  of  all, 
hardly  any  of  the  women  recovering  from  it.  Gonorrhea  is  the  least  dangerous  of 
the  pus  cocci.  Saprophytic  infections  are  so  varied  that  we  cannot  generalize — 
indeed,  some  of  the  bacteria  formerly  held  to  be  saprophytic  have  recently  been 
found  to  possess  invasive  qualities,  for  example,  the  Streptococcus  putridus. 
Others  have  long  been  known  to  possess  them — for  example,  the  Bacterium  coli, 
the  gas  bacillus,  etc.  Since  the  Streptococcus  pyogenes  causes  most  of  the  serious 
infections,  its  demonstration  in  pure  culture,  or  as  the  dominant  organism  in  the 
lochia,  carries  considerable  prognostic  importance.  Unfortunately,  it  is  not  easy 
to  determine,  as  was  already  shown,  whether  the  streptococcus  is  of  the  virulent 
type,  and,  further,  unless  the  bacteriologic  examination  is  made  early  in  the  puer- 
perium,  the  organisms  may  have  disappeared  from  the  vagina.  Syml)iosis  usually 
clouds  the  prognosis. 

In  judging  the  severity  of  any  jiarticular  case  the  above  information  is  first 
considered;  next,  the  apparent  severity  of  the  clinical  manifestations.  If  the  in- 
fection occurs  early  in  labor,  develops  before  it  is  finished,  and  does  not  subside  im- 
mediately, the  uterus  is  emptied — the  disease  is  serious.  If  the  fever  begins  within 
thirty-six  or  forty-eight  hours  after  delivery,  the  same  is  true.  A  single  chill  at  the 
beginning  of  the  disease  is  of  only  moderate  significance,  but  a  second  chill,  or  a 
chill  occm-ring  after  a  preliminary  run  of  fever,  indicat(^s  graver  disease,  since  these 
symptoms  betoken  advancing  infection.  Repeated  chills  in  pyemia  are  not  a  fatal 
symptom,  though  very  distressing  and  somewhat  ominous.  One  of  my  cases  had 
over  100  chills  and  recovered.  Continuous  high  fever  from  the  start  is  an  unfavor- 
able symptom,  as  is  extreme  prostration,  both  usually  indicating  a  bacteremia. 
Remittent  fever  is  less  serious.  Rapid  pulse  is  also  bad — a  sign  of  grave  toxinemia; 
indeed,  the  pulse  is  a  better  indicator  of  the  gravity  of  the  case  than  the  temperature. 
If  the  pulse  remains  around  100,  the  woman  will  rarely  die.  If  it  goes  above  140, 
the  prognosis  becomes  dubious.  A  good  pulse  with  volume  and  force  usually  means 
recovery,  but  if  it  rapidly  increases  in  rate  while  diminishing  in  power,  one  may  de- 
cide that  the  heart  muscle  is  degenerating  under  the  poisoning.  A  sinking  tem- 
perature with  a  running  pulse  almost  always  presages  death,  and  since,  on  the 
graphic  charts,  their  lines  cross,  it  has  been  called  the  cross  of  death.  Restful  sleep, 
a  warm,  moist  skin,  and  appetite  are  good  symptoms.  The  advent  of  septic  endo- 
carditis or  of  septic  jmeumonia  or  pleuritis  immediately  darkens  the  outlook.  De- 
lirium and  even  the  tyi^hoid  state  are  not  necessarily  bad.  ))ut  ominous.  The  gen- 
eral impression  on  the  accoucheur  of  the  severity  of  the  illness,  and  the  feeling  of  the 
patient  herself,  help  a  great  deal  in  making  the  decision,  but  in  regard  to  the  latter 


870  PATHOLOGY   OF   THE    PUERPERIUM 

I  must  say  that  sometimes  very  severe  and  even  fatal  cases  show  remarkable  eu- 
phoria. This  is  most  common  in  peritonitis  toward  the  end:  the  woman  f(>els  well, 
wishes  food,  and  desires  to  get  up,  but  the  Hippocratic  facies,  the  collapse,  the 
thready  pulse  in  a  clammy,  icy  wrist,  show  that  death  is  not  far  distant. 

Unfortunately,  the  laborious  researches  of  von  Rosthorn,  Arnetli,  Burkhard, 
von  Herff,  and  others  on  the  morphology'  of  the  Ijlood  have  produced  no  really  use- 
ful results  so  far  as  prognosis  is  concerned.  Destruction  of  the  red  blood-cori3uscles 
is  the  rule,  which  accounts  for  the  pallor  of  the  women  and  also  for  the  icterus  of 
some  cases  of  infection.  In  severe  toxinemias  or  bacteremias  the  reds  may  sink  to 
less  than  2,000,000.  Poikilocytosis  and  nucleated  reds  appear  in  the  worst  infec- 
tions. Leukocytosis  is  the  rule,  but  is  of  no  prognostic  significance.  There  is  a 
physiologic  leukocytosis  in  the  puerperium  which  may  reach  29,000.  Absence  of 
leukocytosis  shows  lessened  reaction  of  the  puerpera  to  the  attack  of  the  bacteria, 
but  I  have  seen  recovery  take  place  from  severe  infection  with  a  leukocytosis  that  did 
not  exceed  8000.  It  was  hoped  that  the  differential  count  would  give  useful  data. 
In  health,  according  to  Tiirck,  the  relations  of  the  wliites  are  about  as  follows:  Poly- 
morphonuclears, 65  to  75  per  cent. ;  lymphocytes,  20  to  25  per  cent. ;  mononuclears, 
3  to  5  per  cent. ;  eosinophiles,  2  to  3  per  cent.  According  to  Ameth,  increase  of  the 
pol>Tnorphonuclears  indicates  an  effective  reaction  against  the  invaders,  because 
these  leukocytes,  being  older,  have  strongest  phagocytic  power.  Decrease  in  the 
polynuclears  and  increase  in  the  mononuclears  and  neutrophiles,  with  two  or  three 
nuclei,  show  that  the  bacteria  are  using  up  the  former,  while  the  blood-making 
organs  are  filling  the  ranks  with  young  leukocytes.  The  eosinophiles  disappear 
early  in  the  disease.  Reappearance  of  the  eosinophiles  and  increase  of  the  poly- 
morphonuclears may  be  regarded  as  a  sign  of  improvement.  How  far  these  state- 
ments apply  in  practice  is  yet  to  be  determined. 

When  bacteria  are  demonstrated  in  the  blood,  the  prognosis  is  bad,  but  not 
necessarily  fatal.  Lenhartz  reports  17  per  cent,  of  recoveries,  and  Canon  25  per 
cent,  where  such  were  found.  If  they  are  numerous  and  easily  discovered  by  our 
ordinary  cultural  methods,  and  if  they  are  found  in  all  the  examinations,  the  prog- 
nosis is  worse  than  if  they  are  few  in  number  and  discovered  only  once  in  numerous 
tests.  The  hemolytic  aerobic  St>reptococcus  pyogenes  is  very  fatal,  also  the  staphy- 
lococcus (which  seems  to  be  exceptionally  virulent  when  it  invades  the  blood),  the 
Bacterium  coli,  and  the  Bacillus  aerogenes  capsulatus. 

Finally,  in  making  the  prognosis,  the  state  of  the  woman's  previous  constitu- 
tion must  be  debated.  Much  depends  on  the  general  health  of  the  woman — heart, 
lung,  and  renal  and  hepatic  affections  often  seriously  duninishmg  her  chances  of 
recovery. 

Albuminuria  appearing  and  increasing  is  of  bad  omen,  also  the  presence  of 
granular  and  epithelial  casts.  Women  exhausted  by  profuse  hemorrhage,  by  the 
toxemias  of  pregnancy,  by  the  shock  of  severe  and  contusing  operations,  debilitated 
by  alcohol,  syphilis,  tuberculosis,  and  the  acute  diseases — all  are  poor  subjects  for 
an  added  infection. 

Mortality  of  Puerperal  Infection. — In  1909,  in  the  registered  area  of  the  United  States, 
which  comprised  only  .5.5.3  per  cent,  of  the  total  population,  7791  women  died  in  childbirth,  and 
of  these,  3540  died  of  "puerperal  septicemia."  In  1910,  in  the  registered  area,  which  comprised 
58.3  per  cent,  of  the  total  population,  8455  died  in  childbirth,  and  of  these,  4122  died  from  infection. 
These  figun>s  are  taken  from  the  mortality  statistics  of  the  United  States  Bureau  of  the  Census. 
If  the  same  proportion  of  deaths  exists  in  the  non-registered  area,  it  is  safe  to  say  that  every  year 
there  are  lost,  in  the  United  States,  over  GOOO  mothers  from  child-bed  fever.  In  reality  the  num- 
bers are  much  larger.  There  is  no  doubt  that  women  have  died  from  sepsis,  and  the  death  reported 
as  due  to  other  causes,  either  through  mistaken  diagnosis  or  deliberate  concealment.  I  do  not  fear 
to  hazard  the  statement  that  SOOO  women  die  annually  in  the  United  States  from  child-bed  infec- 
tions. When  one  considers  that  the  majority  of  cases  of  puerperal  infection  get  well,  the  conclusion 
is  inevitable  that  the  disease  is  still — in  these  modern  aseptic  and  antiseptic  times — very  prevalent. 

In  England  and  Wal(;s,  exclusive  of  Ireland  and  Scotland,  between  1500  and  2000  women 
die  annually  from  puerperal  sepsis,  and  2200  to  2900  from  the  accidents  of  labor,  but  Sir  William 


DIAGNOSIS    OF    PUERPERAL    INFECTION  871 

J.  Sinclair  asserts  that  the  septic  niortahty  prohahly  varies  between  3000  and  5000  per  year. 
Routh  believes  that  the  last  few  years  show  siifiht  improvement.  In  Ireland  0.327  per  cent. of  puer- 
pera'  die  from  infection  (Hoxall,  1903).  In  Germany  about  oOOO  women  are  lost  each  year  from 
infection,  and  fully  as  many  more  from  accidents  of  childbirth.  Wm  HerfT  recently  called  atten- 
tion to  a  slifjht  but  persistent — and  deplorable — rising  of  tlie  mortality  from  sepsis,  whicli  he 
ascribes  to  the  lack  of  a.septic  practice  hij  the  physicians  and  increa.se  of  obstetric  operating. 

Without  doubt — and  to  our  discredit  must  it  be  said — to<lay  one  woman  in  400  giving  birth 
to  a  child  dies  from  puerperal  infection,  a  humanly  preventable  disease.  In  the  maternities  fatal 
sepsis  has  been  reduced  almost  to  the  vanishing-})oint.  A  sharp  distinction  must  be  made  between 
the  eases  delivered  in  the  hospital  and  treated  exclusively  by  its  officers,  anfl  those  cared  for  out- 
side, before  admi.ssion  to  the  institution,  \\ith  this  separation  of  the  figures  some  maternities 
show  the  ab.sence  of  fatality  in  successive  thousands  of  cases. 

Von  HerlT,  in  I'.KXi,  reported  that  in  liascl,  up  to  that  date,  (5000  cases  had  been  delivered 
without  a  single  death,  due  to  infection  having  been  acquired  in  the  hospital.  Lea  rjuotes  Ahlfeld, 
of  Marburg,  as  having  had  8000  cases  with  one  death,  the  infection  having  been  acfjuired  in  the 
hospital,  but  the  patient  had  examined  herself.  In  the  Rotunda  Maternity,  Dublin,  2()()0  women 
were  delivered  without  mortality  from  infection  caused  in  the  hospital,  and  Dr.  Boxall  gives  the 
record  of  the  York  Road  Lying-in  Hospital,  with  <S373  deliveries  without  death  from  infection, 
ascribable  to  the  hospital  care.  This  is  by  far  the  best  work  yet  reported,  and  is  a  glorious  ac- 
complishment. All  these  institutions  report  deaths  from  infection,  but  after  careful  analy.sis  of 
the  circumstanc^es  cleclare  that  the  cause  of  the  disease  lay  beyond  their  power  of  pre\-ention. 
The  Chicago  Lying-in  Hospital  has  had  2193  cases  without  fatality  from  infection  ac(iuire(l  in 
the  hospital.  One  woman  died  from  peritonitis  caused  by  the  rupture  of  a  gonorrheal  pyosalpinx 
during  normal  labor,  and  another  from  the  rupture  of  a  recto-uterine  abscess  during  operative 
delivery.  These  figures  speak  with  stunning  force  against  the  theory  of  autoinfection  in  its 
strictest  sense.  It  is  a  sad  statement  to  have  to  make  that  the  mortality  in  private  practice 
is  comparatively  much  higher  than  that  of  the  maternities. 

What  can  be  done  by  the  use  of  an  aseptic  technic  is  shown  by  the  results  of  the  obstetric 
dispensaries — institutions  that  care  for  the  poor  of  our  large  cities  in  tlieir  own  homes.  Less 
favorable  conditions  could  hardly  be  imagined  than  those  in  which  such  obstetric  cases  are 
treated,  yet  the  results  challenge  our  admiration.  Lea  .says  that  in  the  out-clinic  of  (^ueen 
Charlotte's  Lying-in  Hospital,  London,  in  1907-OS,  41()o  women  were  delivered  without  a  death 
from  infection.  In  the  first  7000  ca.se.s  of  the  Chicago  Lying-in  Hospital — t he  dispen.sary  service 
— one  woman  died  from  infection,  and  there  was  a  series  of  3990  cases  without  death  from  any 
cause — that  is,  of  casts  handled  exclusively  l)y  the  dispensary  staff.  In  the  total  of  1(3,000  cases 
treated  (exclusively)  to  date,  seven  women  lia\e  died  from  infection.  In  three  cases  the  dis- 
pensary staff  was  probal)ly  to  blame,  though  possibly  on(>  of  the  deaths  could  have  been  avoided 
had  the  patient  not  fallen  into  other  hands  later;  two  of  the  women  had  had  sexual  intercourse 
a  few  hours  before  labor,  in  one  case  the  act  having  ruptured  the  bag  of  waters,  one  was  an 
eclamptic  and  one  woman  had  fever  of  102°  F.  when  the  physicians  arrived  at  her  bed-side.  It 
was  103°  F.  on  the  completion  of  labor,  and  did  not  improve  before  removal  to  a  hospital,  in 
which  she  died.  Another  woman  died  of  acute  peritonitis,  the  cause  being  indeterminable. 
Thus  here  are  16,000  cases,  with  an  institutional  mortality  of  1  in  4000. 

Morbidity  of  Puerperal  Infection. — It  is  safe  to  say  that  for  every  woman  who  dies  from 
puerperal  infection  fi\e  others  suffer  from  it,  but  it  is  impossible  to  prove  the  statement.  The 
morbidity  as  regards  infection  is  the  best  available  test  of  the  efficiency  of  a  maternity's  technic. 
Statistics  from  a  large  number  of  maternities  collected  by  von  Hcrff  and  Lea  show  that  6  to  30 
per  cent,  of  puerpera-  have  fever  postpartinn,  but  it  is  unwise  antl  unjust  to  make  comparisons 
between  these  institutions,  because — (1)  There  is  no  generally  accepted  standard  of  what  consti- 
tutes "fever";  (2)  some  hospitals  take  the  temperature  in  the  axilla,  some  in  the  mouth,  and  a 
few  in  the  rectum;  (3)  some  hospitals  have  trained,  intelligent  nurses,  some  midwives,  more  or 
less  intelligent  and  conscientious;  (4)  some  hospitals  have  four-hour  temperature  readings,  others 
only  A.  M.  and  p.  M.;  (5)  many  thermometers  are  inaccurate  (I  myself  have  noted  inaccuracies  of 
over  1°  F.);  ((>)  .some  authors  omit  the  connnon  initial  elevation  of  temperature  to  10(J°  or  even 
101°  F.  that  follows  delivery  and  sub.sides  within  twenty-four  hours,  while  others  include  it;  (7) 
it  is  impossible  always  to  separate  the  cases  due  to  infection  from  those  due  to  other  non-puerperal 
causes — the  statistics,  therefore,  will  always  have  a  subjective  or  p<'rsonal  bias;  (S)  some  mater- 
nities get  good  material,  others  the  most  unfavorable — for  example,  women  debilitateti  by  priva- 
tion or  constitutional  disease,  heart,  pulmonary,  or  other  visceral  lesions,  gonorrhea,  etc. 

It  is  highly  desirable  that  obstetric  authorities  come  to  agreement  on  a  standard  of  puerperal 
morbidity.  Important  information  could  then  be  ol)tained  as  to  the  relati\e  values  of  various 
methods  of  treatment,  of  the  u.se  and  the  non-u.^^e  of  rul)ber  gloves,  of  the  vaginal  anti.septic  douche, 
of  external  disinfection,  etc.  Not  until  such  a  standard  is  adopted  may  reliable  conclusions  be 
drawn  from  present  statistical  information,  and  for  this  reason  the  statistics  are  here  omitted. 
The  British  Medical  Association  recommended  as  standard — "The  puerperal  morbi(Uty  should 
include  all  fatal  cases  and  also  all  cases  in  which  temperature  exceeds  100°  F.  on  any  two  of  the 
bidaily  readings  from  the  end  of  the  first  to  the  eighth  day  after  delivery."  German  authorities 
adopt  38°  C,  or  100°  F.,  as  the  normal  limit.  In  my  own  practice  every  temperature  above  99.5° 
F.  taken  with  a  certificated  thermometer,  in  the  mouth,  is  regarded  as  morbiil;  indeed,  any  rise 
above  99°  F.  is  viewed  with  suspicion,  and  the  rise  which  so  often  follows  lai)or  is  also  ascribeil  to  an 
infection  and  is  not  held  to  be  a  "fibrin  ferment  fever."  In  my  opinion  this  postpartum  fever  is  due 
to  the  inoculation  of  the  puerperal  wounds  with  the  iiacteria  ever  present  in  the  parturient  canal. 

From  my  own  experience  in  private  practice,  in  practice  in  the  maternity  wards  of  general 
hospitals,  in  a  special  maternity  hospital,  and  in  consultation;   from  my  knowledge  of  the  results 


872  PATHOLOGY    OF   THE    PUERPERIUM 

of  my  colleagues  who  treat  cases  parallel  to  mine  in  the  same  institutions,  and  from  my  observation 
of  the  work  done  in  maternities  at  home  and  aliroad;  from  my  stucUes  of  the  statistical  tables  of 
several  countries  and  of  a  large  number  of  institutions,  details  of  which  it  is  naturall}-  impossible 
to  present  here,  I  liave  come  to  tlie  following  conclusions:  Pueiperal  infection  is  still  very  preva- 
lent—indeed, it  is  perpetually  endemic;  it  kills  1  in  400  women  delivered  of  full-term  children; 
it  leaves  as  incurable  invalids  at  least  ten  times  this  number;  it  is  more  fre(iuent  in  private  prac- 
tice than  in  maternity  practice;  it  is  more  fretjucnt  in  maternities  that  form  an  integral  part  of  a 
general  hospital  thanit  is  in  private  practice;  it  is  least  fref}ucnt  in  the  special  maternity  hospital, 
even  when  the  latter  accepts  infected  cases  (the  danger  of  inf(>ction  is  so  well  recognized  that 
transmission  of  the  disease  to  others  is  prevented);  it  is  more  freciuent  in  maternities  used  for  the 
teaching  of  students  than  in  those  not  so  used,  or  where  only  midwives  or  nurses  are  taught;  it 
is  more  frequent  in  January,  February,  and  March,  the  time  when  the  general  liealth  of  the  people 
is  below  par,  when  fresh  air  and  sunshine  are  at  the  minimum;  it  is  more  frequent  during  the 
prevalence  of  la  grippe,  colds  in  the  head,  pneumonia,  scarlet  fever,  erysipelas,  bacteremia  from 
other  causes  (a  fact  proved  by  CJaIal)in  for  England  and  ^^■ales);  it  is  more  common  among  the 
delicately  brecl  well-to-do  than  among  the  poor,  who,  through  ages  of  squalor  and  filth,  have 
developed  immunities,  which  the  other,  in  their  protected  lives,  do  not  possess.  Medical  practices 
which  are  without  bad  result  among  the  poor  would,  if  applied  to  the  finely  bred  woman,  produce 
effects  horrible  to  contemplate;  it  is  more  frequent  in  the  country  than  in  the  city,  perhaps  because 
so  many  births  occur  in  the  maternities;  it  is  still  carried  about  on  the  person  of  the  accoucheur, 
as  a  rhinitis  or  pharyngitis,  for  example,  and,  in  those  times  when  it  seems  that  an  epidemic  influence 
is  at  work,  the  cause  may  be  sought  in  the  inefficiency  of  the  means  ordinarily  practised  for  its 
prevention  in  the  presence  of  numerous  alien  bacteria.  For  example,  a  certain  practitioner,  fairly 
careful  and  thorough  in  his  aseptic  technic,  may  for  years  have  no  infections.  Suddenly,  when 
there  is  a  prevalence  of  streptococcal  infections,  rhinitis,  sinusitis,  mastoids,  etc.,  he  has  a  succession 
of  septic  cases.  This  means  that  his  ordinary  methods  of  prevention  are  not  efficient  enough  in 
the  presence  of  extra  danger. 

It  is  impossible  to  learn  the  number  of  deaths  that  occur  long  after  parturition,  but  indirectly 
from  its  action,  from  operations  done  to  relieve  the  effects  of  puerperal  infection,  or  from  disease 
of  the  heart,  lungs,  liver,  and  kidneys,  which  took  its  origin  in  a  puerperal  process.  Counting 
such  deaths  would  swell  the  mortality  figures  decidedly.  Likewise  it  is  impossible  to  measure 
the  invalidism  suffered  by  these  unfortunate  women.

CHAPTER  LXVI 
TREATMENT  OF  PUERPERAL  INFECTION 

Prophylaxis  plays  the  transcendently  important  role  in  this  disease.  So  much 
can  be  clone  by  prevention  and  so  little  by  treatment  that  our  efforts  should  be 
concentrated  on  asepsis  and  on  a  physiologic  conduct  of  labor. 

Much,  in  a  preventive  line,  can  be  done  during  pregnancy  to  get  the  woman 
into  perfect  condition  for  the  trial  of  labor.  Local  diseases,  vulvitis,  intertrigo, 
vaginitis,  bartholinitis,  cervicitis,  etc.,  are  to  be  cured  as  long  as  possible  before 
labor  supervenes.  Appendicitis  cases  are  to  be  operated  on  early.  If  not  operated 
on,  care  is  to  be  taken  during  labor  not  to  rupture  a  possible  pus-sac.  The  same 
may  be  said  of  salpingitis,  but  the  diagnosis  of  the  latter  is  harder  to  make.  Sup- 
puration of  the  ear  or  of  the  head  sinuses,  etc.,  should  all  receive  appropriate  treat- 
ment. The  patient  is  to  be  instructed  in  the  principles  of  local  cleanliness,  and 
coitus  and  self-examination  in  the  latter  months  should  be  expressly  forbidden. 
The  gravida  should  not  visit  sick  puerperse  and  should  not  expose  herself  to  contagi- 
ous diseases.  In  the  unavoidable  presence  of  one  of  the  above  conditions,  and  dur- 
ing the  prevalence  of  colds  in  the  head,  grippal,  streptococcal,  and  other  infections, 
the  precautions  to  be  followed  during  labor  are  to  be  redoubled.  For  the  sake  of 
completion  may  be  mentioned  the  prophylactic  use  of  antistreptococcus  serum  in 
cases  where  postpartum  infection  is  feared.  Polano,  in  60  cases,  and  Zangemeister, 
in  his  experiments,  could  find  no  good  in  this  measure  of  immunization.  In  the 
prevention  of  tetanus  prophylactic  injection  of  antitetanic  serum  is  useful,  as  was 
shown  by  the  epidemic  in  Prague. 

The  reader  is  referred  to  the  chapter  devoted  to  the  Conduct  of  Labor  for  the 
details  of  the  methods  of  prevention.  Here  only  the  governing  principles  enun- 
ciated by  Crede  may  be  reiterated:  (1)  Limit,  as  far  as  possible,  the  puerperal 
wounds.  (2)  Prevent  the  infection  of  the  necessary  puerperal  wounds.  Every  puerpera 
is  a  wounded  woman.  It  is  good  surgery  to  limit  the  operative  wound  and  to 
avoid  injuring  the  tissues,  and  the  same  is  true  of  obstetrics.  A  few  concise 
directions  will  indicate  how  this  may  be  done. 

Ad  1:  Limit  the  number  of  internal  examinations  to  an  irreducible  minimum, 
and  make  them  very  gently,  so  as  not  to  tear  the  softened  mucous  membrane.  Con- 
duct the  labor,  so  far  as  possible,  by  external  examination.  The  state  of  the  cervix 
and  the  possible  prolapse  of  the  cord  are  the  only  points  in  labor  indeterminable  by 
external  examination.  The  author  conducts  the  majority  of  normal  labors  with 
one  internal  examination,  often  without  any  at  all,  and  rarely  with  two  or  three. 

Do  not  rupture  the  bag  of  waters  until  there  is  strict  indication  for  it,  and  let 
one  condition  be  a  completely  dilated  os.  The  membranes  dilate  the  cervix  with 
the  least  trauma,  and  also  mechanically  prevent  the  access  of  germs  to  the  uterus. 

Avoid  all  measures  to  shorten  the  time  of  normal  labor,  as  manual  dilatation 
of  the  cervix,  of  the  perineum,  or  having  the  woman  bear  down  before  the  head  has 
slipped  through  the  cervix.  Do  not  give  ergot  until  the  placenta  has  been  delivered. 
Outside  of  its  noxious  action  on  the  child,  it  increases  the  frequency  of  operative 
interference.  Do  not  apply  forceps  mitil  there  is  an  honest,  scientific  indication 
for  their  use.  Do  not  use  douches,  especially  hot  ones  or  antiseptic  ones,  in  normal 
labors.  These  rob  the  vagina  and  cervix  of  their  epithelium  and  their  natural 
protecting  secretions.     Prevent  perineal  and  vaginal  tears,  as  far  as  possible,  which 

S73 


874  PATHOLOGY  OF  THE  PUERPERIUM 

means  a  patient  conduct  of  the  second  stage,  but  do  not  allow  the  other  extreme  of 
practice,  and  permit  the  head  to  pound  for  hours  on  a  rigid  perineum  until  the 
vitalit}'  of  the  tissues  is  lost  and  they  are  bruised  and  infiltrated  with  blood.  Early 
episiotomy  and  forceps  are  more  scientific  procedures. 

The  third  stage  should  be  conducted  as  physiologically  as  possible.  Interfer- 
ence should  be  instituted  only  on  strict  indication — above  all,  manual  removal  of 
the  placenta  should  l)e  attempted  only  when  hemorrhage  occurs  or  the  organ  is 
pathologically  adherent.  Great  care  is  to  be  exerted  to  obtain  the  placenta  and 
the  membranes  complete,  as  retained  portions  of  either  furnish  pabulum  for  the 
organisms  naturally  in  the  vagina,  and  they  retard  involution,  wliich,  when  nor- 
mally progressing,  offers  a  barrier  to  infection.  The  uterus  should  not  be  bruised 
by  too  early,  too  frequent,  and  too  strong  attempts  at  Crede  expression  of  the  pla- 
centa, or  too  much  and  too  forcible  massage. 

The  placenta  and  membranes  should  be  carefully  inspected,  to  determine  if 
pieces  of  the  former  or  shreds  of  the  latter  are  missing.  Such  an  examination  con- 
sumes fully  five  minutes,  and  should  never  l)e  neglected.  It  is  the  keystone  of 
the  treatment  of  the  patient  should  fever  arise  subsequently.  The  cases  in  which 
it  is  impossible  to  determine  this  point  are  rare.  If  a  piece  of  placenta  is  missing, 
it  must  be  removed  at  the  time  of  labor.  If  a  piece  of  membrane  less  than  one-half 
of  the  whole  remains  in  the  uterus,  I  usually  do  not  go  in  after  it.  If  the  uterus 
balloons  out  with  blood,  or  if  there  is  external  hemorrhage,  the  cause  is  frequently 
found  to  be  such  a  piece  of  membrane  ^vrapping  up  a  blood-clot.  Removal  is  then 
indicated.  See  that  the  uterus  is  free  from  blood-clots,  hard,  and  firmly  contracted 
before  you  leave  the  house. 

After  every  operative  delivery,  and  after  every  breech  delivery,  and  in  all  cases 
where  there  has  been  a  very  rapid  dilatation  of  the  cervix,  examine  the  whole 
uterovaginal  tract  for  lacerations.  You  must  know,  without  the  least  suspicion  of 
a  doubt,  w^hether  or  not  there  is  a  perforating  injury  of  the  parturient  canal;  j'ou 
must  determine  exactly  the  number  and  extent  of  the  puerperal  wounds.  This 
advice  is  not  given  for  normal  labors,  but  for  operative  and  abnormal  ones. 

Repair  all  lacerations  of  the  perineum  that  are  deeper  than  one-half  inch. 
A  large  number  of  cases  of  infection  originate  in  the  perineal  wound.  It  is  pref- 
erable to  do  this  after  the  delivery  of  the  placenta,  as  the  parts  are  not  obstructed 
by  flowing  blood,  the  tissues  are  not  so  swollen  and  stretched,  and  one  can  so 
ai range  the  patient  that  better  work  may  be  done.  Then,  too,  if  one  sews  the 
laceration  before  the  placenta  is  delivered,  the  proper  conduct  of  the  third  stage  is 
neglected,  and  also  the  placenta  will,  as  it  passes  over  the  wound,  force  blood 
between  the  stitches,  which  will  prevent  proper  healing.  The  one  consideration 
of  saving  the  accoucheur's  time  should  not  weigh  against  the  above  disadvantages. 

Before  introducing  the  hand  into  the  uterus,  in  any  manipulation,  I  wash 
out  the  introitus  and  the  vagina  with  bichlorid  and  lysol  solutions  on  cotton 
pledgets.  This  is  done  to  avoid  carrying  higher,  or  into  the  uterus,  particles  of 
feces,  etc.,  which  may  have  reached  the  vagina  through  the  various  manipulations 
connected  with  an  operative  delivery. 

When  a  purulent  vaginitis  complicates  labor,  1  per  cent,  lysol  douches  may  be 
given  with  a  view  to  limiting  the  amount  of  pus  ground  into  the  puerperal  wounds 
by  natural  and  operative  processes  and  of  preventing  ophthalmia  neonatorum. 

After  the  puerpera  has  been  cared  for  on  the  lines  just  indicated,  the  parturi- 
ent canal  is  to  be  left  severely  alone.  Make  no  internal  examinations,  give  no 
douches — practise  only  external,  vulvar,  antisepsis.  Only  after  the  puerperal 
wounds  are  w^ell  healed  may  an  internal  or  specular  examination  be  safely  made. 
The  single  indication  for  douches,  in  my  opinion,  is  hemorrhage. 

Ad  2:  Prevention  of  the  infection  of  the  unavoidable  puerperal  wounds  com- 
prises the  principles  and  practice  of  asepsis  and  antisepsis,  and  here,  after  referring 


TREATMENT   OF   PUERPERAL    INFECTION  875 

to  Chapter  XX,  p.  273,  nothing  more  need  be  said  on  this  subject.     Such  a  technic 

shouUl  be  part  of  the  very  body  and  soul  of  the  accoucheur. 

Curative  Treatment. — Few  subjects  in  medicine  present  such  diversity  of 
opinion  as  this  one,  and,  too,  owing  to  the  latest  discoveries  in  bacteriology,  in  the 
action  of  bacteria  and  in  inmmnology,  our  ideas  of  treatment  have  undergone 
radical  changes.  In  general,  it  may  be  said  that  the  polypragmasia  of  former 
times  has  given  way  to  a  more  physiologic  treatment;  that  we  now  rely  more  on 
aiding  and  stimulating  nature's  own  methods  of  combating  the  disease.  The 
discussion  of  this  subject  may  be  divided  into  four  parts, — local,  general,  specific, 
and  surgical  measures, — but  before  considering  these,  the  author  wishes  to  describe 
the  routine  treatment  he  carries  out  in  such  cases. 

When  the  careful  general  medical  examination  has  excluded  all  other  causes 
for  the  illness  and  a  diagnosis  of  puerperal  infection  is  made,  the  woman  is  isolated 
in  the  lightest,  airiest  room  available,  and  put  at  complete  physical  and  mental  rest, 
which  means  that  a  good  obstetric  nurse  is  put  in  charge  of  her.  If  too  poor  to 
obtain  proper  care  at  home,  she  is  sent  to  the  best  hospital  within  her  means.  A 
brisk  cathartic  is  administered  (calomel,  followed  by  a  saline  or  castor  oil) ;  provi- 
sion is  made  for  a  generous  semisolid  diet,  with  much  fluid;  an  ice-bag,  or,  if  the 
patient  prefers  it,  a  warm-water  bag,  is  laid  over  the  uterus;  and  ergot  and  hydras- 
tis  (15  minims  of  the  fluidextract  of  each)  given  by  mouth  thrice  daily.  A  little  of 
the  lochia  is  sent  to  a  laboratory  for  bacteriologic  analysis.  Sutures  in  the  peri- 
neum and  cervix  are  removed  at  once,  to  provide  free  drainage,  and  the  gaping 
wounds  swabbed  with  pure  tincture  of  iodin,  but  this  is  the  extent  of  the  local 
treatment.  Developments  are  then  awaited.  Even  if  it  is  certain  that  there  is 
something  in  the  uterine  cavity,  the  uterus  is  not  invaded.  The  patient  may  be 
propped  up  a  little  to  favor  drainage,  but  curetage,  ecouvillonage  (brushing  out  the 
uterus),  douches,  packing,  etc.,  are  not  employed.  The  sole  indication  for  such 
treatment  is  hemorrhage  from  the  uterus.  If  the  woman  does  not  show  immediate  im- 
provement, the  various  specific  remedies  are  considered  {vide  infra).  When  the  course 
of  the  disease  becomes  chronic,  the  patient  is  carefully  watched  for  signs  of  localiza- 
tion of  the  infection,  and  in  a  very  few  cases  this  point  is  attacked  by  operation. 

This  policy  of  non-interference — this  nihilism  with  respect  to  active  local  and 
general  measures — is  the  result  of  my  experience  in  the  Dispensary  Service  of  the 
Chicago  Lying-in  Hospital.  In  the  last  seventeen  years  15,784  women  were  deliv- 
ered at  term.  Of  these,  about  10  per  cent,  had  fever  over  100°  F.  In  only  one  case 
was  the  uterine  cavity  invaded  and  a  douche  given;  in  the  others  we  followed  the 
plan  above  outlined,  and  only  7  women  died  of  infection,  but  2  of  these  died  under 
questionable  treatment  in  other  hands.  In  none  of  the  5  cases  did  the  subsequent 
course  show  that  the  event  might  have  been  different  had  a  more  active  policy  been 
followed.  With  the  thoughtful  clinician  the  article  of  jMermann  (Arch.  f.  Gyn., 
1907,  vol.  iv)  carries  great  weight.  Mcrmann,  in  330  cases  of  fever  of  all  grades  of 
severity,  and  treated  purely  expectantly,  lost  only  7  women.  In  30  of  the  cases  the 
disease  was  critical,  and,  even  using  these  only  for  comparison,  the  results  compare 
favorably  with  all  other  methods  of  treatment.  On  the  other  hand,  I  can  recall  nu- 
merous cases  where,  before  adopting  the  above  methods,  I  caused  severe  illness  by 
active  local  treatment,  and  I  am  not  sure  but  what  some  of  the  women  died  because 
of  the  curetage,  pelvic  drainage,  etc.,  intended  for  their  relief.  This  has  been  the 
experience  of  my  colleagues,  working  in  the  same  hospitals  with  me,  and  whose  re- 
sults I  have  been  able  to  follow. 

Local  Treatment. — The  local  treatment  of  infection  is  the  attempt  to  remove 
the  offending  bacteria  and  their  toxins,  to  take  away  their  pabulum, — clots,  mem- 
branes, placental  fragments,  decidua, — and  to  destroy  those  bacteria  and  neutralize 
those  toxins  which  remain  in  the  genital  canal  after  the  mechanical  cleansing.  The 
idea  is  excellent — if  it  were  only  safer  to  carry  it  out. 


876  PATHOLOGY    OF   THE    PrERPERIUM 

111  the  hope  of  accomplishing  these  purposes  the  followinp;  methods  are  prac- 
tised : 

(1)  Intra-uterine  douches  of  normal  saU  solution  or  of  antiseptic  solutions, 
such  as  bichlorid  of  mercury,  lysol,  carbolic  acid,  alcohol,  iodin,  etc.,  if  the  attendant 
believes  that  such  remedies  have  real  bactericidal  action  on  germs  already  mside 
the  living  tissues.  Harvej^  knew  about  douches,  but  Ruleau,  in  1704,  first  used 
them  for  fetid  lochia.  They  enjoyed  the  greatest  vogue  in  the  years  1881  to  1900, 
often  being  given  in  normal  puerpera  as  a  routine,  but  lately  have  lost,  in  large 
part,  the  confidence  of  the  accoucheurs.  The  objections  to  the  uterine  douche  are 
— (a)  It  is  inefficient,  the  bacteria  being  beyond  reach  within  fifteen  minutes  after 
they  are  inoculated;  (b)  it  is  painful,  sometimes  violent  uterine  action  being  set 
up,  and  if  (c),  as  sometimes  happens,  part  of  the  liquid  escapes  through  the  tubes 
into  the  peritoneal  cavity,  syncope,  vomiting,  and  peritonitis  may  result;  (d)  the 
nervous  shock  sometimes  causes  syncope,  even  convulsions  and  coma  (Bar) ;  (e) 
the  antiseptic  employed  may  be  directly  poisonous,  over  50  cases  of  bichlorid  and 
as  many  more  from  carbolic-acid  poisoning  being  on  record,  the  chemical  being  ab- 
sor])ed  by  the  uterus,  or  gaining  entrance  to  the  blood  through  the  sinuses  (I  know  of 
two  which  have  not  been  recorded) ;  (/)  air-embolism;  (g)  perforation  of  the  uterus; 
(h)  profuse  hemorrhage;  (i)  chill  and  fever — the  infection  having  been  reinocu- 
lated  by  the  douche;  (j)  sudden  death,  which  is  usually  from  air-embolism,  but  may 
be  due  to  cardiac  paralysis;  (k)  the  infection  may  be  carried  up  higher  in  the  par- 
turient canal,  heretofore  unaffected. 

Continuous  irrigation  of  the  uterus  was  recommeii.Ied  in  1877  by  Schiicking. 
It  had  some  vogue,  and  until  very  recently  was  occasionally  practised,  but  is  now 
abandoned. 

(2)  Swabbing  out  the  uterus  with  gauze  wound  around  a  long  dressing  forceps, 
with  or  without  antiseptic  or  caustic  solutions.  Alcohol,  carbolic  acid,  iochn,  and 
combinations  of  these  have  been  used.  Pincus  steams  out  the  uterine  cavity  with 
live  steam,  but  has  had  hardly  any  imitators,  and  these  not  a  second  time.  If  it 
were  possible  to  isolate  the  causative  bacteria  of  the  infection,  theoretically  it  might 
be  a  promising  procedure  to  pack  the  uterine  cavity  with  gauze  soaked  in  a  l^acterin 
or  immune  body. 

(3)  Brushing  the  surface  of  the  endometrium  with  a  round  brush,  similar  to 
those  which  are  used  for  cleansing  bottles  (ecouvillonage).  Introduced  by  Doleris, 
it  was  quite  popular  with  French  accoucheurs,  and  is  recommended  by  Lea  as  safe 
and  efficient.  The  Germans  do  not  use  the  Ijrush,  nor  do  American  obstetricians. 
I  regard  it  as  dangerous,  but  perhaps  not  so  much  so  as  the  curet. 

(4)  Curage,  or  digital  removal  of  the  contents  of  the  uterus,  is  reconnnended 
by  a  large  number  of  authorities  hete  and  abroad,  among  whom  a  few  may  be 
mentioned:  Whittridge  Williams,  Hirst,  Clalabin,  Jellett,  Sinclair,  Bumm,  Chrobak, 
Ahlfeld,  Schauta,  Bar,  Pinard,  and  Pestalozza.  Some  recommend  aseptic  or  anti- 
septic douches  before  and  after  operation,  or  packing  the  uterus  with  sterile  or 
antiseptic  gauze. 

(5)  Curetage. — This  operation,  introduced  in  1850  l)y  Recamier,  who  invented 
the  curet  for  the  purpose,  has  obtained  a  very  generalized  employment.  Some 
operators  use  a  blunt,  others  the  sharp,  curet ;  some  use  the  instrument  as  a  routine 
practice  as  soon  as  febrile  symptoms  appear;  others  use  it  only  if  the  finger  fails  to 
remove  firmly  adherent  masses;  some  repeat  the  operation  once  or  oftener;  some 
pack  the  uterus  with  antiseptic  gauze  at  the  completion  of  the  operation;  others 
do  this  only  in  the  event  of  severe  hemorrhage,  etc.  The  operation  has  always  had 
opponents,  prominently  among  the  earliest  of  whom  may  be  mentioned  Karl 
Schroder,  and  lately  many  authorities  are  arrayed  against  the  practice — Whittridge 
Williams,  Noble,  Cragin,  Edgar,  Watkins,  Pies,.  Bumm,  Leopold,  Fehling,  Kronig, 
Veit,  Olshausen,  and  others,  some  of  wliom  formerly  advised  the  procedure.     The 


TREATMENT    OF    PUERPERAL    INFECTION  877 

dangers  of  curetage — and  tlicsc  arc  present  with  hotli  blunt  and  sharp  instruments — 
and  with  eurage  with  the  finger  are:  (a)  The  dehcate  l)ank  of  leukoeytes,  the  wall 
nature  throws  up  to  limit  the  spread  of  the  bacteria,  is  broken  through  at  innumer- 
able places,  and  the  bacteria  literally  ground  into  the  lymph-spaces  and  the  ven- 
ous lumina — it  is  a  thorough  vaccination  or  inoculation  of  the  uterine  tissues,  and 
resembles  raking  the  soil  after  strewing  it  with  seed;  (6)  curetage,  no  matter  how 
expertly  done,  cannot  remove  all  the  diseased  tissues.  The  bacteria,  within  fifteen 
minutes  after  inoculation,  are  already  out  of  its  reach,  and,  further,  at  autopsy  in 
cases  where  the  curet  had  been  used  invariably  parts  of  the  endometrium  c(;uld  be 
proved  never  to  have  been  touched  by  the  instrument;  indeetl,  even  the  whole 
placenta  has  been  found;  (c)  perforation  of  the  uterus  is  a  common  occurrence,  and 
almost  always  fatal  from  peritonitis;  even  the  greatest  gentleness  may  not  prevent 
such  an  accident,  because  in  some  cases  the  muscle  is  as  soft  as  butter;  (d)  hemor- 
rhage from  the  reopened  placental  sinuses,  even  air-embolism,  has  l)een  reported; 
(f)  the  freshly  united  wounds  are  torn  open  and  new  ones  created,  into  all  of  which 
infection  is  ground;  (/)  a  pyosalpinx  or  other  pus-sac  may  be  ruptured  l^y  the  man- 
ipulations. It  seems  about  as  reasonable  to  curet  the  nose  and  throat  in  cases  of 
diphtheria  as  to  curet  the  uterus  for  sepsis. 

(6)  Emptying  the  uterus  with  polypus  forceps  is  a  very  dangerous  procedure, 
because  parts  of  the  uterine  nmscle,  even  the  intestine  and  omentum,  have  l)een 
pulled  out  under  the  impression  that  ovular  remnants  were  being  removed.  The 
forceps  may  be  used  only  to  remove  pieces  of  tissue  floating  freely  in  the  uterine 
cavity. 

(7)  Drainage  of  the  uterus  with  rubber  or  glass  tubes  is  the  ]iractice  of  some 
French,  Italian,  and  American  accoucheurs. 

(8)  Packing  the  uterus  with  gauze,  or  draining  it  with  the  same,  may  be 
employed  to  stop  hemorrhage  after  the  operations  just  considered,  and  they  are 
employed  by  some  as  directly  antiseptic  measures.  The  technic  of  these  operations 
does  not  differ  from  those  jierformed  in  the  treatment  of  a])ortion,  to  which  the 
reader  is  referred  for  details. 

For  the  last  five  years  I  have  practically  dispensed  with  local  treatment  in 
puerperal  infection,  being  convinced  that  it  does  much  more  harm  than  good. 
Only  if  the  woman  is  having  uterine  hemorrhages  do  I  interfere,  and  then,  by  pack- 
ing the  uterus  with  2  per  cent,  iodoform  gauze  to  stop  the  flow  and  aid  the  expulsion 
of  the  retained  masses  causing  it.  This  packing  is  repeated,  if  needed,  daily  for 
several  days.  Often  the  foreign  matter  comes  away  when  the  gauze  is  removed, 
and  usually  the  temperature  comes  doAvn,  the  patient's  general  condition  improving. 
Only  after  the  local  barriers  are  considered  strong  enough  and  involution  of  the 
uterus  well  advanced  is  the  removal  of  the  retained  material  attempted.  This  is  safe 
only  after  the  temperature  has  been  normal  two  or  more  weeks.  One  waits  as  long 
as  possible.  Nature  often  does  wonders.  Most  authorities  do  not  take  this  radical 
position.  Bumm,  Williams,  Hirst,  the  French,  and  many  advise  a  primary  palpa- 
tion of  the  uterine  cavity  with  the  finger  and  the  immediate  removal  of  its  contents, 
but  they  all  emphasize  the  danger  of  the  procedure  when  the  infection  is  strepto- 
coccal, urging  that  it  then  be  omitted.  It  has  already  l)een  proved  that  it  is  impos- 
sible to  say — certainly,  at  the  first  examination — whether  a  given  infection  is,  oris 
not,  streptococcal,  and,  further,  l^efore  the  streptococcus  can  be  demonstrated  the 
infection  is  through  the  ut(>rine  wall  and  beyond.  On  the  other  hand,  if  the  infec- 
tion is  saprophytic,  Init  little  danger  need  be  api^rehended  from  it,  and  it  is  safe  to 
wait  a  few  days  to  see  what  course  the  disease  will  take.  A\inter,  of  Kcinigsberg, 
Mermann  (loc.  cit.),  Saft,  and  Baumm,  of  Breslau,  Watkins,  and  Ries,  of  Chicago, 
are  opposed  to  local  treatment,  and  Crede,  of  Leipsic,  shortly  before  his  death, 
strongly  emphasized  its  dangers,  advising  its  total  discontinuance.  It  is  gratifying 
to  note  that  one  voice  after  another  is  being  raised  against  douches,  curetage, 


878  PATHOLOGY    OF   THE    PUERPERIUM 

curage,  and  other  local  interferences  with  the  processes  of  healing  adopted  by  nature, 
and  the  author  hopes  that  the  curet  will  soon  be  recognized  as  a  criminal  instru- 
ment in  simple  puerperal  infection,  and  that  the  other  operations  will  be  reduced 
to  the  one  indication — to  stop  hemorrhage.  (For  the  treatment  of  pus  collections 
see  Pelvic  Peritonitis.) 

General  Treatment. — Everything  that  will  improve  the  woman's  general  health 
will  help  her  throw  off  the  disease,  and  the  attendant  should  count  no  effort  lost 
that  will  increase  her  resisting  powers.  Fresh  air  is  important,  anil  I  have  emploj'ed 
the  outdoor  treatment  with  good  results,  though  not  so  good  as  expected.  Sleep 
is  a  prime  necessity,  and  if  procuring  mental  and  physical  quiet  do  not  bring  it, 
morphin  may  be  used.  ]Morphin  is  also  given  for  pain.  Pain  is  depressing  and 
fatiguing.  In  a  maternity  the  sick  woman  should  be  isolated — first,  because  of  the 
danger,  recognized  by  practicalh'  all  authorities,  of  her  being  the  beginning  of  an 
epidemic  of  puerperal  infection,  and,  second,  to  insure  her  quiet,  ^^isitors  are 
excluded,  and  every  one  about  the  house  should  bear  a  cheerful  mien.  Nursing 
the  child  is  stopped,  first,  because  the  mother  needs  all  her  reserve  force  to  combat 
the  infection;  second,  the  acts  of  nursing  are  disturbing  and  tiring,  and,  tliird,  the 
child  may  be  infected.  In  those  cases  where,  contrary  to  orders,  nursing  has  been 
continued,  the  child  does  not  always  suffer  from  the  poor  quality  of  the  milk, 
though  it  often  does. 

For  the  fever,  as  a  rule,  nothing  need  be  done.  If  continuously  high,  cool 
sponging,  cool  packs,  or  the  cool  bath  may  be  used — rarely  the  bath,  because  it 
involves  too  much  exertion  for  the  patient,  and  a  weak  heart  may  go  default; 
further,  in  parametritis  and  perimetritis  the  patient  may  not  be  moved  much. 
Antipyretics  are  contraindicated.  Medicines  are  very  sparingly  used.  Of  tonics, 
quinin  is  the  best,  in  two-  or  three-grain  doses.  Hexamethylenamin  is  given  if 
there  are  signs  or  fears  that  the  urinary  tract  may  be  involved  in  the  mfection. 
Drugging  is  avoided,  so  far  as  possible,  first,  because  it  does  little  good,  and,  second, 
because  it  spoils  the  stomach,  the  most  important  ally  of  defense.  Alcohol, 
formerly  considered  almost  specific  in  all  kinds  of  infections,  has  lost  favor.  At 
most  the  system  can  utilize  Y2  ounce  a  day,  and  there  is  no  objection  to  giving  this 
amount  in  the  form  of  eggnog  or  a  wine  to  stimulate  a  flagging  appetite. 

The  Bowels. — In  prolonged  cases  an  occasional  laxative  is  ordered,  and,  as  was 
said,  a  brisk  cathartic  forms  part  of  the  routine  treatment  at  the  beginning  of  the 
disease.  Diarrhea  may  be  one  of  nature's  methods  of  ridding  the  system  of  toxins, 
and  is  not  interfered  with  unless  pronounced,  and  when  it  Ijegins  to  exhaust  the 
patient.  When  the  diarrhea  is  too  marked,  charcoal  and  salol  may  be  tried,  but 
magnesia  usta,  in  dram  doses  every  three  hours,  may  do  better.  Opium  and  starch 
enemata  may  be  necessary.  Vomiting  is  always  a  bad  symptom,  and  if  bilious, 
almost  always  means  a  fatal  ending.  Food  by  the  mouth  is  withheld  for  a  while 
and  rectal  feeding  instituted — saline  solution  with  3  drams  of  grape-sugar  added  to 
each  quart,  by  the  drop  method.  If  the  vomiting  persists,  the  stomach  may  be 
washed  out.  It  is  surprising  how  much  greenish-black  fluid  is  removed,  and  the 
patient  usually  feels  much  relief  for  several  hours.  Later,  against  peritonitic 
vomiting,  we  stand  powerless  and  dismayed.  When  food  cannot  be  administered 
by  the  stomach  and  the  rectum  proves  too  irritable,  it  has  been  recommended  to 
sew  the  intestine  to  a  tiny  opening  in  the  upper  linea  alba  and  inject  predigested 
foods  through  the  fistula  into  the  bowel.  Success  rarely  follows  such  operations, 
because  the  women  do  not  die  from  starvation,  but  from  toxinemia. 

Meteorisin  in  peritonitis  is  a  troublesome  condition.  Overfeeding  and  cathartics 
are  to  be  avoided  and  enemata  given.  Milk  and  molasses,  of  each  one  pint,  form 
a  very  efficient  enema  in  causing  flatus  to  pass.  Physostigmin  salicylate,  -^ 
grain,  may  be  given  every  four  hours  for  four  doses,  but  in  my  experience  it  has 
failed  to  relieve  the  distention.  The  rectal  tube  gives  some  relief.  If  the  stomach 
is  dilated,  the  patient  is  to  lie  on  the  abdomen  and  the  foot  of  the  bed  is  raised,  or 


TREATMENT    OF    PVERPER.\L    INFECTION  879 

the  stomach  is  washed  out — a  sovereign  remedy.  In  the  rarest  cases  the  lx)wel  may 
be  punctured  and  the  gas  removed  through  a  fine  needle,  a  procedure  I  have  never 
had  occasion  to  practise.  The  small  intestine  may  be  opened  through  a  tiny  incision 
near  the  navel  and  drained.  In  one  case  it  seemed  to  me  that  the  electric  \Tbrator, 
allowed  to  play  on  the  belly,  stimulated  peristalsis. 

For  the  chills,  the  patient  is  covered  warmly  and  given  a  hot  drink.  If  the 
chill  is  prolonged,  ^  grain  morphin  is  given  hN-podermically. 

Attention  is  given  the  heart,  and  all  exertion  of  the  patient  is  forbidden  in 
order  to  spare  its  strength.  Cardiac  stimulants  are  withheld  until  al>solutely 
needed.  My  experience  with  digitalis,  etc..  and  strychnin  has  been  disappointing. 
For  the  syncopal  attacks  common  in  severe  bacteremias  an  abundance  of  fresh  air 
and  pure  oxygen  are  useful. 

Special  attention  is  directed  to  the  diet,  and  an  abundance  of  sugar  and  pro- 
teins is  pro%'ided — less  of  fat.  Milk,  buttermilk,  matzoon,  kumiss,  eggs,  jellies, 
cereals,  sugar,  ice-cream,  and  gelatin  in  all  forms  are  permissible. 

Finally,  the  mental  titate  of  the  patient  should  be  treated.  She  should  be 
buoyed  up  with  the  hope  and  assurance  that  she  will  recover — indeed,  speaking 
from  experience,  I  can  say  that  even  the  apparently  hopeless  cases  sometimes  get 
well,  and  I  am  convinced  that  the  mind  of  the  patient  has  considerable  to  do  with 
her  struggle  with  the  infection. 

Specific  Treatment. — Since  the  bacteria  are  beyond  the  reach  of  the  antiseptic 
douche  and  the  curet.  we  try  to  get  at  them  and  to  neutralize  or  remove  their 
poisons  by  way  of  the  blood.  We  try  to  do  this  in  two  ways — first,  by  direct  anti- 
septic or  bactericidal  action;  second,  by  stimulating  the  antibacterial  and  antitoxic 
power  of  the  blood,  as  well  as  we  know  these  forces.  Some  of  the  remedies  to  be 
mentioned  partake  of  both  these  qualities.  In  the  first  class  may  be  listed  iron, 
mercury,  quinin,  alcohol,  iodin,  silver,  and  a  host  of  others.  Mercury  in  the  form 
of  inunctions  was  recommended  by  Fehling  thirty  years  ago.  and  as  intravenous 
injection,  by  Kesmarsky,  in  1S94  (BarsonyV  One-fourth  grain  of  bichlorid 
dissolved  in  three  ounces  of  water  is  given  in  the  median  basilic  vein  daily.  Neph- 
ritis is  a  contraindication.  My  associate.  Dr.  St  owe,  at  my  suggestion,  employed 
it  in  34  cases,  but  without  decided  benefit,  though  with  no  resulting  harm.  It 
increases  leukoc^'tosis  and  raises  the  opsonic  index  i^Polizzotti),  and  perhaps  com- 
bines with  some  of  the  toxins.  Silver,  in  the  form  of  a  colloidal  salt. — collargol, — 
was  introduced  by  Crede  in  1895.  As  an  ointment,  miguentum  Crede  I  have  used 
it  freely  without  observing  the  least  effect.  Given  per  rectum  it  has  also  failed. 
Given  intravenously  (10  c.c.  of  a  1  to  2  per  cent,  solution  daily)  it  produced  an 
effect,  but  this  is  not  always  good.  I  have  given  in  all  20  injections.  In  one  case 
I  felt  that  the  patient  was  benefited,  and  I  considered  the  remedy  harmless  imtil  one 
woman  nearly  died  in  collapse  immediately  following  the  injection,  after  which  the 
temperature  went  to  106  F.  She  was  sick  with  pyemia  for  two  months  but 
ultimately  recovered.  It  is  certam  that  the  injections  cause  leukocytosis,  which 
may  have  had  something  to  do  with  the  reported  cures.  In  doses  which  it  is  safe 
to  put  into  the  blootl  it  has  no  bactericidal  action.  Driessen.  van  de  Velde, 
Ribins,  Treub,  Boimaire,  Bar,  and  Albrecht  have  reported  some  good  results,  but 
by  no  means  invariable  improvement.  Kronig.  von  Rosthorn,  Chrobak.  Fehling, 
Harrison,  Polak.  Jones,  and  others  report  more  failures  than  successes.  Injections 
of  other  antiseptics  into  the  blood  have  hardly  historic  interest,  though  the  results 
of  salvarsan  tri'atinent  iiulicate  a  fertile  field  for  experiment. 

Salt  Solution. — This  is  a  remetly  which  has  been  much  laudetl  in  the  last  few- 
years  in  the  treatment  of  all  forms  of  infection,  and.  in  fact,  it  is  very  valuable,  but 
it  is  not  a  panacea.  The  best  method  of  administration  is  by  slow  infusion  in  the 
rectum — the  drop  method.  The  solution  is  kept  hot  in  a  vacuum  bottle  hung  near 
the  bed.  and  the  fiow  is  so  regulated  by  an  artery  forceps  clamping  the  tube  leailing 
into  the  rectum  that  from  30  to  40  drops  flow  in  each  minute.    If  the  rectum  becomes 


880  PATHOLOGY   OF   THE    PUERPERIUM 

intolerant,  the  injection  may  l)e  made  intermittently,  or  the  hypodermic  or  intra- 
venous method  emi)loyed,  hut  eitlun-  is  much  more  distressing  to  the  patient,  and 
there  is  the  danger  of  overloading  the  circulatory  system,  causing  crdema  pulmonum. 
The  action  of  the  salt  solution  is  unknown.  It  prol)ably  does  not  wash  the  toxins 
from  the  blood,  because  these  are  usually  so  bound  onto  the  cells  that  only  bio- 
chemic  action  can  loosen  them.  Leukocytosis  is  stimulated,  but  probably  the  good 
effects  of  the  salt  solution  lie  in  the  stimulation  of  the  heart,  kidneys,  skin,  and 
intestine,  keeping  up  the  tonus  of  the  vessels,  in  relieving  thirst  and  fatigue — thus 
improving  the  general  resistance  of  the  patient.  The  stinmlation  of  the  pelvic 
circulation  should  also  be  thought  of. 

Nuclein,  in  the  form  of  sodium  nucleinate,  produces  leukocytosis,  but  its 
employment  in  sepsis  has  not  improved  the  results.  In  many  cases  where  proto- 
nuclein  has  been  given  I  could  never  observe  any  benefit,  but  Hofbauer,  Schauta, 
and  others  have  reported  some  successes  with  nuclein. 

Serum  Treatment. — After  sixteen  years  of  trial,  in  which  time  all  kinds  of 
sera  have  been  tried,  we  are  forced  to  the  reluctant  conclusion  that  antistrepto- 
coccic serum  does  not  cure  streptococcic  puerperal  infection.  This  was  the  con- 
clusion reached  by  Williams,  Pryor,  and  Fry  in  1899,  and  further  experience  only 
confirms  their  findings.  Sera  prepared  from  the  horse,  inoculated  with  single 
or  many  human  strains  of  streptococci,  and  from  convalescents  from  such  infection, 
all  are  of  doubtful  utility,  though  they  are  rarely  injurious.  Since  we  know  that 
the  streptococcus  produces  no  exotoxin,  it  is  not  possible  to  produce  in  any  animal 
an  antitoxin — as  in  diphtheria.  That  means  that  we  cannot  produce  "passive 
immunity"  in  the  human  by  the  use  of  such  foreign  serum;  therefore  a  serum,  to 
be  efficient,  must  be  either  bactericidal  or  must  be  able  to  supply  substances — 
immune  bodies — which,  when  united  with  the  complement  of  the  individual,  pro- 
duces the  antibacterial  agent,  or  it  must  have  some  power  of  causing  the  blood  of 
the  patient  to  form  opsonins  or  other  antibacterial  substances,  or  at  least  a  protective 
leukocytosis.  In  other  words,  it  must  be  able  to  develop  "active  immunity." 
Recently,  Weaver  and  Tunnicliff  claim  that  antistreptococcus  serum  augments 
phagocytosis.  If  we  had  a  serum  which  was  bactericidal,  it  might  be  dangerous  to 
exhibit  it  in  streptococcal  infections,  because  the  endotoxins  thus  liberated,  added 
to  the  previously  existing  toxinemia,  might  increase  the  dose  to  a  fatal  one. 
This  may  explain  some  of  the  bad  results  in  cases  where  the  serum  has  been  admin- 
istered late  in  the  disease.  Large  numbers  of  cases  have  been  treated  by  Bumm, 
Chrobak,  Gordon,  and  others,  including  myself,  and  a  study  of  the  reports  is  not 
encouraging.  In  three  cases  of  my  owti  I  was  convinced  that  the  serum  at  least 
contributed  something  to  recovery.  Erythema  at  the  site  of  injection,  and  gener- 
alized urticaria,  swelling  of  the  joints  (simulating  pyemic  joints),  and  moderate 
increase  of  the  fever  I  have  observed,  but  never  any  indications  of  anaphylaxis, 
though  the  serum  was  repeated  daily  for  a  week.  Anaphylaxis  has  occurred  when 
a  longer  interval  than  seven  days  elapsed  between  two  injections.  To  get  any  good 
effect  the  serum  must  be  given  in  large  doses  (60  to  100  c.c.  in  twenty-four  hours) 
very  early  in  the  disease,  and  general  experience  has  shown  that  it  is  useless 
in  pyemia,  thrombophlebitis,  cellulitis,  and  peritonitis.  In  early  cases  of  acute 
streptococcic  bacteremia,  especially  if  complicated  by  erysipelas,  one  may  hope  for 
some  effect,  but,  to  repeat,  the  result  is  often  disappointing.  As  a  prophylactic, 
the  antistreptococcic  serum  is  useless,  1)ut  the  tetanus  serum  useful. 

Vaccine  Therapy. — LTp  to  the  present  the  clinical  results  of  the  vaccine  treat- 
ment of  acute  puerperal  infections  have  been  negative,  a  conclusion  reached  by 
a  committee  composed  of  Williams,  Cragin,  and  Newel  in  1910.  Polak,  however, 
recommends  a  mixed  stock  vaccine  in  doses  large  enough  materially  to  increase 
leukocytosis. 

Phagocytosis  is  one  of  the  means  of  defense  of  the  liody  against  infection,  and,  though  it  has 
long  Ijeen  believed,  Wright  has  proved,  that  certain  bodies  are  prothiced  by  the  blood-serum — at 


TREATMENT    OF   PUERPERAL    INFECTION  881 

least  are  produced  somewhere — wliicli  prepare  the  bacteria  for  the  devouring  leukocytes.  Wright 
called  these  bodies  uiMoniits.  By  comparing  the  number  of  bacterid  which  the  leukocytes  of  a 
patient  will  ingest  with  the  number  which  the  leukocytes  of  a  normal  individual  will  ingest  under 
identical  cultural  conditions,  the  j)ower  of  tli(>  patient's  serum  to  jjroduco  an  opsonin  sjiecific  for 
the  particular  infection  will  be  determined.  Tiiis  is  the  opsonic  index  of  the  patient,  and  it  varies 
as  the  patient  is  conquering  or  not  conquering  the  infecting  organism.  Wright  found  that  injec- 
tion into  the  cellular  tissue  of  sterilized  cultures  of  bacteria  containing,  of  course,  the  endotoxins 
as  well  as  the  bodies  of  the  deail  baciteria,  causes  an  increase  of  the  opsonins  of  the  blooii,  that  is, 
of  those  opsonins  which  facilitate  phagocytosis  of  the  particular  organism,  and  this  fact  is  discov- 
erable by  the  elevation  of  the  opsonic  index. 

It  would  seem,  therefore,  that  if  a  patient  were  exposed  to  a  certain  infection  and  we  injected 
the  dead  bacteria  and  their  endotoxins,  that  the  blood  of  the  patient  would  be  so  ffirtified  that 
when  the  invading  bacteria  arrive,  they  would  be  met  l)y  such  a  resisting,  (;psonizing  l)lood  that 
they  would  be  rapidly  engulfed  bj'  the  phagocytes.  And  clinical  experience  tends  to  bear  this  out, 
because  in  cholera,  plague,  typhoid,  and  dysentery  such  immunizing  vaccinations  have  proved 
of  decided  value. 

It  would  also  seem  rational  to  believe  that  if  the  patient  suffered  from  a  local  infection  in 
which  the  general  reaction  was  not  enough  to  produce  c>fficient  local  phagocj'tosis,  the  injection 
of  a  vaccine  would  aid  the  wall  of  leukocytes  in  its  fight  with  the  bacteria,  and  experience  bears 
this  out  in  many  cases.  It  has  oft(>n  been  observed  that  if,  for  example,  a  breast  abscess  with 
many  sinuses  develops  a  pocket  of  pus,  cutting  this  open  is  followed  by  rai)id  improvement  of 
the  whole  breast.  This  is  a  sort  of  autovaccination,  and  the  whole  body  is  called  upon  to  furnish 
antibodies  for  the  fight  going  on  in  the  breast. 

When  the  blood  is  infected  or  full  of  bacteria  and  toxins,  it  would  seem  irrational  to  inject 
more  endotoxins,  and  experience  confirms  this  statement. 

It  is  generally  admitted  that  in  acute  puerperal  infections  vaccine  therapy  is 
useless  and  sometimes  harmful.  It  is  not  always  possible  to  isolate  the  causative 
bacterimn  or  bacteria.  In  chronic  local  infections,  suppurating  cellulitis,  peri- 
metritis, pyosalpinx,  thrombophlebitis,  the  use  of  vaccines  promises  more  success. 
The  best  results  have  been  obtained  in  chronic,  local,  staphylococcal  infections,  in 
tubercular,  Bacterium  coli,  and  gonococcal  processes,  while  with  the  streptococcus 
less  headway  has  been  made.  Stock  vaccines  are  useful  in  some  cases,  but  it  is 
probably  best  to  use  autogenous  vaccines,  that  is,  those  cultivated  from  the  patient 
herself.  Prophylactic  vaccinal  immunization  has  thus  far  proved  futile.  With 
what  bacterium  should  we  work?  The  subject  is  still  in  the  experimental  stage, 
and  the  treatment  is  not  yet  sufficiently  tried  out  to  be  recommended  for  general 
practice. 

The  Abscess  of  Fixation. — It  has  been  known  for  a  long  time  that  if  a  case  of  sepsis  has  a 
focus  of  free  suppuration,  recovery  is  very  probable,  and  Fochier,  in  1892,  advised  the  injection  of 
turpentine  into  the  thigh,  with  the  object  of  making  an  abscess  and  thus  inducing  leukocytosis. 
Voiturier,  in  1909,  reported  120  cases  and  reviewed  the  hterature.  The  results  have  not  gained  any 
general  recognition  for  the  procedure. 

Surgical  Treatment. — Reference  has  already"  been  made  to  the  treatment  of 
pelvic  inflammations  by  operation,  and  no  real  difference  of  opinion  exists  regarding 
the  procedures  advocated  for  the  treatment  of  localized  suppurations.  Two  radical 
operations,  however,  have  been  employed  in  the  treatment  of  severe  infections, 
about  which  there  is  still  much  to  be  learned.  One  is  extirpation  of  the  uterus,  the 
other,  ligation  of  the  pelvic  veins,  with  a  view  to  stopping  the  progress  of  a  thrombo- 
phlebitis. 

Hysterectomy. — Schultze  removed  a  uterus  containing  an  infected  placenta  in 
1886,  and  the  patient  recovered,  and  since  then  the  operation — total  hysterectomy — 
has  been  done  several  hundred  times,  but  with  not  enough  success  to  give  it  a  firm 
place  in  our  therapy.  At  the  Congress  in  Rome  in  1902  the  subject  was  one  of 
the  main  themes,  and  again  in  IMadrid  in  1903.  Fehling  reported  in  Rome  a  mor- 
tality of  55.7  per  cent.,  and  Cortiguera,  in  ^Madrid,  51.8  per  cent.;  Doleris,  95  per 
cent.;  ]\Iouchotte  (all  abortion  cases),  43.3  per  cent.  The  main  difficulty  lies  in 
placing  the  indication.  It  is  generally  admitted  that  in  the  following  conditions — 
in  all  of  which  the  local  lesion  is  the  predominant  factor — hysterectomy  is  justifi- 
able: (1)  Rupture  of  the  uterus  or  vagina  with  infection,  perforation  of  the  uterus 
with  beginning  peritonitis,  or  ])erforation  of  the  uterus  during  the  local  treatment 
of  an  infection  within  it;  (2)  mfection  of  a  fibroid,  or  when  a  fibroid  has  been  much 
56

PATHOLOGY  OF  THE  PUERPERIUM 


bruised  by  an  operative  delivery  and  infection  is  feared  (a  fibroid  pohpus  is  often 
removable  from  below);  (3)  cancer  of  the  uterus;  (4)  infection,  with  a  molar 
pregnancy;  {o)  abnormal  adherence  of  the  placenta  and  infection;  (G)  incarceration 
of  aJl  or  of  a  part  of  the  ovum,  for  example,  missed  abortion  or  labor  with  infection 
(in  the  latter  three  instances  the  difficulty  of  removal  of  the  masses  in  the  usual 
manner  must  be  also  considered);  (7)  uterine  abscess;  (8)  gangrene  of  the  uterus. 
It  has  also  been  suggested  to  remove  the  uterus  in  cases  of  peritonitis,  extensive 
involvement  of  the  tubes  and  ovaries,  and  in  uterine  emphysema  (Denielin),  but 
the  shock  of  such  operations  is  very  badh'  borne  by  these  intensely  septic  patients. 
The  greatest  danger  is  from  peritonitis,  if  such  is  not  already  present,  and  it  is 
impossible,  with  our  present  technic,  to  avoid  soiling  the  peritoneum  to  some 
extent  when  the  whole  uterus  is  removed.  If  supravaginal  amputation  ^\-ith  extra- 
peritoneal treatment  of  the  stump  is  practised,  soiling  the  peritoneum  may  be 
avoided  (v.  Herff). 

;Much  more  uncertainty  exists  as  to  the  propriety  of  removing  the  uterus  in

cases  of  bacteremia,  or  at  least  in  cases  of  severe  endometritis  and  uterine  Ij'mph- 
angitis  and  phlebitis,  when  the  infection,  presumably,  is  still  more  or  less  limited 
to  the  uterus.  There  is  the  point.  If  w^e  could  tell  when  the  infection  is  likely  to 
pass  the  line  of  safety,  we  would  know  when  to  remove  the  uterus,  and  experience 
has  shown  that  uteri  are  usually  removed  too  late  to  do  any  good,  and  in  those 
cases,  where  the  courageous  operator  has  done  hysterectomy  early,  he  could  never  be 
sure  that  the  mutilation  of  the  patient  was  demanded.  The  operation  may  have 
killed  her,  or  if  she  got  well,  may  not  have  contributed  to  her  recover}^  but  has 
rendered  her  sterile.  My  oA\'n  experience  with  the  operation  is  nil — I  have  never 
seen  a  case  where  I  thought  it  could  possibly  save  life,  and  in  many  critical  cases 
recovery  ensued  without  it.  If  a  general  bacteremia  exists,  no  one  would  expect 
any  good  from  the  operation.  Williams,  I^a,  and  Edgar  take  the  same  position. 
Septic  patients  are  the  very  poorest  subjects  for  operations  and  anesthetics,  espe- 
cially chloroform  (L.  Guthrie),  and  there  is  no  doubt  in  my  mind  but  that  many 
puerpera;  annually  lose  their  lives  because  of  them.

CHAPTER  LXVII 
DISEASES  OF  THE  BREASTS 

FUNCTIONAL  DISTURBANCES 

The  most  common  disorder  affecting  the  breasts  is  simple  engorgement.  The 
general  notion  is  that  ^\^th  engorgement  the  breasts  are  overfilled  with  milk. 
This  is  true  only  in  part.  While  a  small  amomit  of  milk  forms  spontaneously 
in  the  breasts,  the  symptoms  are  due  to  lymphatic  and  venous  stasis.  One  can 
see  this  in  some  cases,  even  the  skin  being  edematous.  The  engorgement  occurs  on 
the  second,  third,  or  fourth  day,  when  the  "milk  comes  in,"  and  it  may  occur  at 
the  time  of  suddenly  weaniilg  the  child,  when  the  usual  relief  produced  by  nursing 
is  absent. 

Symptoms. — The  breasts  are  very  heavy,  painful,  and  hot;    they  feel  warm, 


Fig.  7GS. — Massage  of  Rreast.     Even  Compression'  of  Entire  Breast.     First  Motion. 


but  there  is  no  rise  of  body  temperature.  There  is  no  such  thing  as  "milk-fever" — 
a  fever  the  ancients  ascribed  to  the  engorgement  of  the  breasts  on  the  third  or  fourth 
day.  Fever  at  such  time  is  usually  thie  to  infection.  Examination  of  the  breasts 
shows  them  to  be  much  enlarged,  tend(>r,  hard,  sometimes  edematous,  and  of  a 
bluish,  mottled  appearance.  The  nipple  is  flattened  so  that  the  child  cannot  grasp 
it,  and  the  secretion  of  milk  may  be  suspended — the  breasts  are  choked  up  with 
swelling.  The  part  of  the  gland  running  up  into  the  axilla  enlarges  too,  and  the 
patient  cannot  bring  her  arm  to  the  side. 

If  let  alone,  the  engorgement  gradually  disappears,  the  gland  becomes  soft,

and  the  milk  flows  readily  when  the  child  nurses.     If  irritated  by  too  nmcli  or  too 
rough  massage,  by  breast-pumps,  and  by  too  frequent  nursing,  the  engorgement  is 
slower  in  going  do^^'n,  but  it 
will  gradually  disappear. 

Treatment. — Since  the 
determination  of  lymph  and 
of  blood  to  the  breast  is 
due  to  hyperactivity,  seda- 
tive remedies,  not  stimula- 
tion, are  needed.  A  saline 
cathartic  may  be  given  to 
deplete  the  system ;  Hquids 
by  mouth  are  restricted,  and 
the  breast  is  put  at  rest  as 
far  as  possible,  which  means 
that  the  periods  between 
nursings  are  to  be  length- 
ened. A  tight  breast- 
binder  is  applied,  supple- 
mented by  ice-bags  if  the 
pain  is  marked.  Some 
patients  prefer  warmth — 
when  a  warm  wet  boric 
dressing  may  be  ordered. 
Soranus,  of  Ephesus,  a.  d. 
100,  said  not  to  pump  the 
breasts,  because  it  increased 
their  activity.     jNIassage  of 

the  breasts  is  employed  in  rare  cases,  and  is  practised  as  follows.  Alassage  and 
the  iLse  of  the  breast-pump  are  contraindicated  if  there  is  the  least  suspicion  of 
inflammation. 

The  operator  sterilizes  his  hands  and  anoints  the  breasts  with  sterile  albolene  or  oil.  The 
first  motion  (Fig.  768)  is  one  of  even  compression  of  the  whole  breast.  Both  hands  are  spread 
out  as  evenly  and  smoothly  as  possible  over  the  breast,  and  firm  compression  is  exerted  against  the 
chest.     The  blood  and  lyinph  are  thus  pressed  out  and  away  from  the  gland.     On  removing  the 

fingers  one  ma^'  see  depressions  in  the  surface.  This  pres- 
sure is  not  painful,  but  the  contrary.  After  this  even  pres- 
sure has  been  practised  a  few  minutes  and  all  the  gland  cov- 
ered, gentle  circular  strokings  are  made  from  the  nipple  to- 
warcl  the  periphery  (Fig.  769).  The  four  fingers  make  circles 
around  the  nipples,  pressing  harder  as  they  go  away  from 
the  nipple.  (See  diagram,  Fig.  770.)  The  breast  is  steadied 
by  the  other  hand. 

After  circling  the  breast  twice  the  third  motion  is  in- 
stituted (Fig.  771 ).  One  hand  steadies  the  brea.st,  while  four 
fingers  of  the  other  hand  wipe  the  milk  toward  the  nipple. 
.\ny  milk  formed  is  thus  squeezed  out  of  the  nipple.  This 
is  the  leiust  important  of  the  three  motions.  The  la.st  motion 
is  a  repetition  of  the  first  motion,  and  nearly  alwaj's  the 
patient  will  feel  much  relieved  by  the  procedure,  even  though 
no  milk  has  been  expressed.  The  breasts  are  now  bandaged 
smoothly  and  tightly. 

FiG.770.-DiAGRAMOFOrT^vARD.'=THOK-  Polygalactia  is  the  abnormal  increase  of  milk 

secretion.  It  occurs  mainly  in  women  of  sthenic 
habit,  and  usually  subsides  in  a  few  days  without  treatment  or  with  the  measures 
just  considered. 

Hyperlactation  is  a  voluntary  condition.  It  means  that  nursing  is  prolonged 
beyond  the  customary  eight  or  nine  months.  One  case  came  to  my  notice  where 
a  wet-nurse  suckled  three  successive  children  in  the  same  familv  without  harm  to 


886 


PATHOLOGY   OF   THE    PUERPERIUM 


herself  and  with  benefit  to  the  nursHngs.  Ploss  says  that  such  a  practice  is  common 
in  Spain,  and  that  the  Japanese  women,  the  Chinese,  Armenian,  and  more  or  less 
civilized  tribes  nurse  their  children  for  sevei'al  years — some  even  up  to  fifteen. 
There  is  a  popular  fallacy  among  the  poor  that  nursing  prevents  conception. 
Hyperlactation  is  usually  bad  in  its  effects  on  the  general  health  of  the  woman, 
causing  emaciation,  asthenia,  oligemia,  backache,  pain  in  the  breasts,  drawing  into 
the  shoulders  while  nursing,  anorexia,  and  general  neurasthenic  symptoms.  Head- 
ache, cramps  in  the  shoulder  muscles,  amaurosis,  and  lactation  psj'choses  have 
been  observed.  More  important  is  the  usual  hyperinvolution  of  the  uterus, — 
the  so-called  lactation  atrophy, — which,  if  the  cause  is  not  early  removed,  may 
lead  to  permanent  changes  in  the  organ.  The  uterus  is  so  small  sometimes  that 
it  can  hardly  be  found.  A  tul)erculous  lesion  may  become  active  in  these  conditions. 
The  treatment  begins  with  weaning  the  child;  then  tonics,  the  compound  syrup  of 
h^-pophosphites,  forced  feeding,  and  outdoor  living  are  prescribed.

Galactorrhea. — Continuous  flowing  of  a  milk-like  secretion  from  the  breasts, 
irrespective  of  nursing,  and  persisting  after  weaning,  is  called  galactorrhea.  It  is 
very  rare  and  rather  intractable.  The  cause  is  unknown,  but  the  disease  is  more 
frequent  in  neurotic  women,  and  in  some  cases  abnormal  practices  on  the  breasts 
may  be  suspected  if  simulation  and  exaggeration  are  eliminated.  It  may  be  uni^ 
lateral  or  bilateral,  intermitting  for  a  few  days  or  weeks,  to  recur  again;  may  follow 
abortions  or  full-term  labors,  may  be  slight  in  amount  or  profuse,  as  much  as 
several  cjuarts  being  lost  dail3\  My  case  continued  for  four  years,  but  was  free 
from  the  flow  during  two  intervening  pregnancies,  and  her  milk  disagreed  with  the 
children,  so  that  they  had  to  be  wet-nursed.  Recovery  occurred  when  a  small 
abscess  near  the  nipple  was  opened.  Perhaps  a  chronic  galactophoritis  may  explain 
some  of  the  cases  of  galactorrhea.  Cases  are  on  record  of  the  flow  lasting  from 
eleven  to  thirty  years.  The  health  usually  suffers  more  or  less, — a  condition  called 
"tabes  lactea," — but  it  may  not  be  affected  at  all. 


DISEASES    OF   THE    BREASTS  887 

Treatment. — Compression  of  the  lireast  b\'  binder  is  first  practised.  lodid  of 
potash,  generally  recommended,  failed  in  my  oami  case.  A  chronic  galactophoritis 
should  be  looked  for,  and,  if  found,  the  inflamed  portion  of  the  breast  excised. 
Chloral,  belladorma,  antip^Tin,  bromids,  and  ergot  have  all  been  tried,  with  varj'ing 
failure.  Return  of  the  menstruation  is  usually  accompanied  by  stopping  of  the 
flow,  and  therefore,  perhaps,  efforts  to  favor  the  return  of  the  menses  may  be  useful. 
Attention  to  the  general  health  is  advisable,  and  a  little  wholesome  neglect  of  the 
local  condition  to  distract  the  patient's  mind  from  it  may  also  be  useful. 

Abnormal  Milk. — Remarkable  as  it  may  seem,  the  milk  of  the  mother,  although 
plentiful,  ma\'  not  agree  with  the  child.  The  author  has  seen  cases  where  it  seemed 
to  act  like  an  irritant  intestinal  poison,  and  fatalities  have  even  been  reported. 
These  have  all  been  neurotic  mothers,  and  most  of  them  in  the  higher  classes. 
Chemic  and  microscopic  examinations  have  not  given  satisfactory'  explanations. 
The  condition  may  or  may  not  recur  in  subsequent  pregnancies. 

The  child  will  refuse  the  breast,  in  which  case  the  milk  may  have  a  foreign 
taste,  or  it  will  vomit  the  ingested  milk  or  have  a  diarrhea  from  it,  sometimes  with 
fever.  The  milk  may  appear  yellower  and  thicker  in  these  cases,  showing  either  a 
persistence  of  the  colostrum  or  an  increase  in  fat  and  proteids — that  is,  it  is  too  rich. 
Curiously,  sometimes  a  child  will  refuse  one  breast  and  accept  the  other;  in  a  case 
of  this  kind  the  milk  of  one  breast  was  said  to  be  salty. 

If  the  milk  is  believed  to  disagree  with  the  child,  causing  green,  acrid  stools, 
the  nursing  should  be  discontinued  for  forty-eight  hours,  the  breasts  being  regularly 
emptied  in  the  mean  time  by  the  breast-pump.  The  child  is  fed  on  a  substitute 
milk,  and  at  the  end  of  this  period  another  trial  is  made  of  the  mother's  milk. 
If  it  again  causes  intestinal  disturbance,  the  wisest  course  to  pursue  is  to  obtain  a 
wet-nurse  for  the  child. 

If  the  mother's  milk  is  deficient  in  one  or  the  other  ingredient,  the  physician 
■mil  instruct  the  nurse  to  give  an  adcUtional  feeding  of  this  or  that  preparation  of 
sugar,  cream,  barley-water,  etc.,  after  each  nursing.  Not  much  may  be  expected 
from  dieting  the  mother.  Illness  of  the  mother  affects  the  quality  of  the  milk, 
rendering  it  indigestible,  and  also  diminishing  the  amount.  Bacteria  circulating 
in  the  maternal  blood  are  excreted  in  the  milk,  which  is  true  of  tuberculosis, 
streptococcemia,  pyococcemia,  and  perhaps  for  malaria.  The  infant  may  be  in- 
fected from  the  germs  thus  swallowed,  or  from  the  germs  contained  in  pus  which 
comes  from  a  mammary  abscess.  Exceptions  to  this  statement  are  not  rare.  I 
have  seen  septic  women,  even  pneumonia  cases,  nurse  their  babies  with  impunity. 
A  woman  with  diphtheria,  given  antitoxin,  may  nurse.  That  drugs  administered 
to  the  mother  pass  over  to  the  fetus  is  well  knowTi. 

Strong  emotions  certainly  affect  the  milk,  causing  indigestion,  diarrhea,  green 
corrosive  stools,  even  convulsions  and  death  of  the  infant,  many  authentic  cases 
of  which  are  on  record. 

Agalactia. — One  of  the  commonest  complaints  of  nursing  mothers  is  scarcity 
or  lack  of  milk.  Total  absence  of  milk  is  found  onlj-  when  the  breasts  are  absent, 
a  rare  anomaly.  The  causes  of  deficient  milk  secretion  are  general  weakness  or 
ill  health;  malformations  or  diseases  of  the  nipples,  which  render  nursing  impossible 
or  too  painful;  occlusion  of  the  milk-ducts,  or  destruction  of  gland  tissue  from 
mastitis;  insufficient  stimulation  of  the  breast  by  a  puny  child ;  inadequate  amount 
of  gland  tissue  as  a  congenital  anomaly,  which  might  be  hereditary,  successive 
generations  of  women  not  having  nursed  their  children;  disuse  of  the  breast  in 
successive  pregnancies;  old  primiparity — women  with  the  first  child  after  thirty- 
five  seldom  being  able  to  nourish  the  infant;  starvation,  the  wasting  diseases,  and 
the  effects  of  febrile  affections;  emotional  states,  a  quiet,  placid  disposition  con- 
tributing to  a  good  supply,  worry,  fright,  pain  and  anger,  reducing  or  temporarily 
stopping  the  flow;  lack  of  love  for  the  child  may  reduce  the  amount;  menstruation 


PATHOLOGY  OF  THE  PUERPERIUM 


rarely  reduces  it;  obesity — but  not  invariu])ly;  hemorrhage  during  hil)or;  inter- 
ruption of  lactation  for  any  cause.  The  milk  usually  is  not  so  abundant  when 
nursing  is  resumed.  I  have  seen  the  milk  return  five  weeks  after  the  child  had  been 
removed  from  the  breast,  and  cases  are  on  record  of  its  return  months  afterward. 
Several  reports  of  nursing  of  the  child  bj'  its  own  grandmother  are  authenticated, 
and  in  certain  tribes  of  savages  such  a  custom  is  common. 

Symptoms. — A  large  breast  does  not  mean  a  good  supply  of  milk,  since  it  may 
be  made  up  mainly  of  fat,  with  little  gland  tissue.  Small  breasts  with  thin  skin  and 
blue  veins  coursing  under  the  surface  usually  give  plenty  of  milk. 

The  symptoms  of  deficient  milk-supply  are,  first,  the  distress  of  the  child — its 
loss  in  weight;  second,  pain  in  the  breasts  and  the  absence  of  secretion.  The 
child  is  unsatisfied  with  the  nipple;  he  may  suck  for  a  short  while,  but,  finding 
nothing  there,  will  refuse  it  and  cry.     After  supplemental  feeding  he  goes  to  sleep. 


Fig.   772. — SxiMt'LATivc;   .Massage. 


When  there  is  plenty  of  milk  the  mother  can  feel  it  leave  the  breast  and  see  the 
infant  swallow.  There  are  also  some  drops  of  "white  nourishment"  around  the 
mouth.  These  are  all  absent  in  agalactia.  Weighing  the  child  before  and  after 
nursing  proves  the  lack  of  milk.  If  the  mother  persists  in  nursing  after  the  supply 
has  diminished,  the  act  (!omes  to  be  attended  with  pain  in  the  breasts,  radiating 
around  to  the  back,  first  only  during  the  nursing,  later  in  the  intervals  also.  Unless 
nursing  is  interrupted,  serious  inroads  on  the  woman's  health  may  result. 

Treatment. — If  there  is  not  enough  milk  in  the  breasts,  an  attempt  may  be  made 
to  stunulate  the  secretion  by  diet,  cool  baths,  and  massage  of  the  breasts,  but  only 
a  few  cases  are  amenable  to  treatment.  Medicines  have  very  uncertain,  if  any, 
action.  Malt  extract,  somatose,  or  other  preparations  vaunted  to  stimulate  the 
secretion  may  be  prescribed.  The  author's  experience  with  malt  preparations  is 
that  they  often  fatten  the  patient  and  dry  up  the  milk. 

By  increasing  the  licjuids  in  the  diet  the  total  quantity  of  milk  may  sometimes, 


DISEASES    OF   THE    BREASTS 


889 


but  not  always,  be  increased.  Wlwn  the  milk  supply  is  not  augmented,  the  pa- 
tients put  on  fat.  Milk  may  be  given  in  largo  quantities,  also  water,  very  weak  tea, 
chocolate,  oatmeal  and  barley  gruels,  and  oyster-stews,  in  addition  to  the  regular 
diet.  The  effect  is  not  permanent,  and  too  much  water  thins  the  blood.  Alcoholic 
drinks  should  be  restricted,  or,  better,  avoided,  and  certainly  l)y  a  mercenary  wet- 
nurse.     Alcoholics  are  not  good  for  the  infant. 

Cool  full  baths  stimulate  the  skin  and  the  l)reast  also.  They  may  be  taken 
daily  at  about  80°  to  84°  F.  The  whole  body  should  be  Ijriskly  rubbed  with  a 
coarse  towel,  avoiding  the  mammae.  Bier's  method  of  producing  artificial  engorge- 
ment has  been  applied  to  the  breast  to  stimulate  the  flow  of  milk.  The  results 
thus  far  have  been  fair. 

Massage  of  the  breasts  stimulates  the  formation  of  milk.     When  massaging 


the  breast  for  this  purpose,  the  rules  given  on  p.  885  do  not  apply.  One  wishes 
here  to  irritate  the  gland.  This  is  done  by  raising  the  whole  breast  from  the 
chest-wall  (Fig.  772)  and  working  it  gently  between  the  fingers.  Care  should  be 
used  not  to  bruise  the  delicate  organ,  as  an  abscess  may  result.  The  gland  is  then 
held  against  one  hand,  while  the  tips  of  the  outspread  fingers  of  the  other  hand  make 
circular  movements  all  around  its  periphery  (Fig.  773). 

Electricity  has  been  tried,  with  indifferent  success.  The  best  stimulant  for 
the  milk  secretion  is  a  vigorous  infant. 

One  should  not  be  discouraged  too  soon,  as  the  establishment  of  the  milk 
secretion  is  sometimes  slow.  In  one  case  sufficient  milk  did  not  come  until  the 
fifth  month.  Often,  after  the  patient  is  up  and  gets  outdoors,  the  milk  comes  in 
larger  quantities.  One  may  be  misled  to  believe  that  this  is  the  action  of  some 
special  drug  or  of  feeding.     If,  however,  the  measures  instituted  have  no  effect,  it 


890  PATHOLOGY    OF   THE    PUERPERIUM 

is  wiser  to  discontinue  them  as  soon  as  this  fact  is  apparent.  Too  great  zeal  in 
forcing  the  breasts  to  act  may  result  in  mastitis. 

Dr3dng  up  the  Milk. — Of  all  the  measures  recommended  for  this  purpose,  the 
author  has  found  the  following  the  simplest  and  quickest.  Liquids  in  the  diet  are 
reduced,  a  saline  cathartic  given  on  two  successive  days,  a  firm  breast-binder  is 
applied,  and  the  breasts  then  left  absolutely  alone.  Pumping  and  massage  only 
stimulate  the  gland  to  further  action.  Drugs  are  dangerous  or  useless.  If  the 
engorgement  following  the  weaning  is  very  marked  and  painful,  the  treatment 
described  on  p.  885  may  be  employed. 

"Caked  Breast." — So-called  "caked  breast"  is  a  local  engorgement  affecting 
one  or  more  lobules  or  lobes.  It  is  sometimes  due  to  occlusion  of  one  or  more  of 
the  lactiferous  ducts,  but  may  be  a  simple  congestion,  due  to  injury,  which  may  have 
antedated  the  gestation.  A  lump  made  up  of  hard,  convoluted  masses  of  gland 
tissue  is  found  occupjdng  one  or  more  quadrants  of  the  organ,  which  is  tender  to 
the  touch,  but  presents  no  signs  of  real  inflammation,  nor  is  there  any  general  reac- 
tion. "Caked  breast"  does  not  usually  lead  to  mastitis,  though  it  is  easy  to  under- 
stand that  the  bacteria  normally  present  in  the  tubuli  lactiferi  could  thus  more 
easily  attain  invasive  qualities.  If  such  a  breast  is  roughh"  handled,  as  by  ill- 
directed  massage,  infection  is  prone  to  develop. 

Treatment. — Outside  of  instructing  the  nurse  and  the  patient  to  leave  the 
breasts  alone,  to  protect  them  from  injurj^,  not  to  attempt  to  massage  the  lumps 
away,  nothing  is  done.  If  the  breasts  are  very  painful,  an  ice-bag  or  a  wet  warm 
dressing  may  be  applied. 

DISEASES  OF  THE  NIPPLES 

Sore  nipples  are  a  frequent  complication  of  the  first  weeks  of  nursing.  They 
are  worthy  the  attention  of  the  accoucheur,  because  thej^  are  exceedingly  painful,

may  prevent  lactation  entirely,  thus  harming  the  child,  and  may  lead  to  infection 
of  the  breasts,  which  may  result  in  abscess  or  even  in  death  of  the  puerpera.  Over 
half  of  nursing  mothers  suffer  from  sore  nipples;  primipara  more  than  multiparae; 
blonds,  particularly  red-haired  women,  more  than  brunets,  who  usually  have  a

thicker  skin;   old  primipara?  more  tlian  young  ones,  and  they  are  especially  common 
if  the  nipple  is  retracted  or  deformed  (Fig.  774).     If  the  nipple  is  flat  oreven  inverted, 
the  child  will  be  unable  to  get  hold  of  it,  and  if  efforts  at  nursing  are  too  long  per- 
sisted in,  engorgement,  cracks,  and  fissures  occur, 
and,  infection  being  thus  introduced,  causes  abscess. 
The  conditions  causing  sore  nipples  are  erosions,  blis- 
ters, cracks  or  fissures,  and  ulcerations.     Erosions  are 
caused  by  the  maceration  of  the  thin  epithelium  and 
the  sucking  of  the  infant,  which  thus  exposes  the  rete. 
Sometimes  the  epithelium  is  raised  up  as  a  blister  b}' 
the  intense  suction,  and  the  blister,  bursting,  leaves 
the  eroded  rete.     If  infection  is  added,  the  process 
may  become  ulcerative.     If  the  skin  cracks,  which 
is  especially  likely  to  occur   at  the  bottom   of   a 

crevice  in  the  nipple,  a  little  blood  is  poured  out ;  it  hardens  to  a  scab  under  which 
a  droplet  of  pus  sometimes  is  found.  Nursing  breaks  off  the  crust,  and  if  the  part 
is  not  treated,  a  deep  ulcer  may  form.  Cracks  are  either  circular  or  vertical.  The 
cracks  which  run  circularly  are  usually  at  the  base  of  the  nipple,  at  its  junction

with  the  areola,  and  if  the  ulceration  is  deep,  the  nipple  may  be  partly  or  wholly 
amputated.  Vertical  cracks  may  split  the  nipple  into  two.  Bacteria  are  always 
present  on  and  in  sore  nipples,  and  may  cause  sickness  in  the  baby.  If  the  cracks 
bleed,  the  child  may  swallow  blood,  which  reappears  in  the  stools  or  vomit — melaena

spuria.     Occasionally  slight  rises  of  temperature  in  the  mother  are  due  to  infected 
nipples. 

The  treatment  of  sore  nipples  begins  during  pregnancy.  (See  p.  230.)  If  the 
■svoman  complains  of  pain  when  the  child  niu'ses,  an  inspection  of  the  nipples  is 
to  be  made — ^with  a  magnifying-glass,  if  necessary.  Some  neurotic  women  have 
pain  while  nursing,  even  in  the  absence  of  disease  of  the  nipples — sometimes  so 
much  that  nursing  is  impossible  in  spite  of  sedatives  and  soothing  local  applications. 

A  l)lister  is  to  be  opened  by  a  fine  sterile  needle  and  the  child  withheld  from  the 
nipple  for  thirty-six  hours.  Cracks  and  ulcerations  are  first  cleansed  with  hydrogen 
dioxid,  then  one  of  the  following  measures  employed:  Leaden  nipple-shields 
(Fig.  775)  are  worn  between  nursings;  the  crack  or  ulcer  is  touched  with  2  per  cent, 
nitrate  of  silver  solution  morning  and  night,  and  this  is  allowed  to  dry  in  in  the 
sunlight;  the  whole  nipple  may  be  painted  with  the  same;  a  50  per  cent,  alcohol 
compress  is  laid  on  the  nipple  for  an  hour  thrice  daily;  glycerol  of  tannin,  glycerin 
and  boric-acid  applications,  a  salve  of  equal  parts  of  castor  oil  and  bismuth,  may 
be  applied;  compound  tincture  of  benzoin,  allowed  to  dry  in;  collodion.  Only  the 
first  four  are  used  by  the  author,  and  in  the  order  given.  A  glass  nipple-shield  is 
ordered  for  the  nursing.  Sometimes  a  teterelle,  used  for  nursing,  as  in  Fig.  776, 
wall  aid  in  the  cure.  The  attendant  is  warned  to  be  scrupulously  aseptic  in  the 
care  of  the  breasts  and  nipples,  because  of-  the  great  danger  of  infection.  The 
breast  is  not  to  be  touched  by  the  nurse,  the  nipple  being  washed  with  sterile  boric 
solution  by  means  of  sterilized  cotton  wound  on  tooth-picks — the  so-called  appli- 
cators. It  may  be  necessary  to  stop  nursing  from  the  breast  until  the  crack  has 
healed,  and  if  the  sore  positively  refuses  to  cicatrize,  it  may  be  wisest  to  suspend 
lactation  entirely  to  prevent  a  breast  abscess.  This  is  especially  true  of  the  inverted 
and  deformed  nipples,  and  particularly  if  the  milk  is  scarce.  Such  a  combination 
almost  inevitably  leads  to  mastitis,  which  the  woman  ought  to  be  spared. 

MASTITIS 

Inflammation  of  the  breast  occurs  almost  exclusively  in  nursing  women.  Cases 
have  been  found  during  pregnancy,  even  in  the  non-pregnant,  and  exceedingly 
rarely  in  men.  The  predisposing  causes  are  cracks,  fissures,  and  ulcers,  which  in 
turn  are  caused  by  deformities  of  the  nipple  and  occur  in  primiparse  oftener.  While 
bacteria  are  the  direct  cause  of  mastitis,  and  while  they  may  often  be  found  in 
apparently  healthy  breasts,  an  exciting  agent  is  often  necessary.  Such  are  bruising 
of  the  breast  by  injury,  which  may  have  been  remote,  by  massage,  too  much  pump- 
ing of  the  breast,  squeezing  it,  or  efforts  to  make  it  secrete  milk  when  it  is  physically 
unable  to  do  so.  Simple  milk  stasis  or  local  or  general  engorgement  seldom  leads 
to  abscess,  if  it  ever  does,  alone. 

The  germs  which  have  been  found  in  mastitis  cases  are  the  Staphylococcus 
albus  and  aureus,  the  Streptococcus  pyogenes,  the  Bacillus  coli,  the  pneumococcus, 
certain  anaerobes,  the  Oidium  albicans,  and  blast omycetes  (van  de  Velde). 
Symbiosis  may  be  present.  These  microorganisms  are  brought  to  the  breasts  by 
the  hands  of  the  attendants,  the  linen,  etc.,  or  by  the  patient  herself,  the  usual 
source  being  the  lochia.  In  general  hospitals  unusual  and  severe  infections  may  be 
brought  to  the  breasts.  The  child  may  be  the  source  of  the  infection,  having 
thrush  or  Bednar's  aphtha)  (the  lesions  of  which  usually  contain  both  the  strepto- 
coccus and  staphylococcus),  pharyngitis,  ophthalmia,  coryza,  or  pemphigoid  or 
pustular  eruptions  on  the  face,  etc.  Without  doubt  some  of  the  cases  are  caused 
by  the  attainment  of  invasive  qualities  of  the  bacteria  normally  inhabiting  the  outer 
milk-ducts  in  the  nipple.  In  1893  I  proved  that  the  staphylococcus  existed  in  the 
milk  of  apparently  healthy  women.  When  the  breast  is  overstimulated  or  hurt, 
the  Vjacteria  invade  it.  Finally,  it  is  possible  for  the  germs  to  get  to  the  breasts 
via  the  blood,  as  is  sometimes  observed  in  septicopyemia,  but  this  is  very  rare. 


DISEASES    OF   THE    BREASTS 


893 


Forms  of  Mastitis  (Fig.  777). — The  infection  may  be  limited  to  the  areola 
outside  the  lamina  cribrosa,  forming  an  abscess  running  around  the  nipple,  or  in 
one  of  the  tubercles  of  Montgomery,  or  in  the  milk-glands  attached  to  them; 
second,  the  infection  creeps  along  the  tubuli  lactiferi  into  the  parenchyma  of  the 
gland;  this  is  called  parenchymatous  or  glandular  mastitis  or  galactophoritis; 
third,  the  bacteria,  gaining  admission  to  the  connective  tissue  through  a  crack  or 
deep  fissure,  burrow  into  the  fat  around  the  lobes  and  lobules,  causing  interstitial 
or  phlegmonous  mastitis  or  lymphangitis;  this  cellulitis  may  be  superficial  or  deep; 
occasionallj^  the  latter  two  forms  are  combined;  fourth,  the  infection  passes  directly 
through  the  gland  to  the  areolar  tissue  under  it  on  the  chest-wall,  producing  here 
a  submammary  abscess. 

Symptoms. — The  parenchymatous  form  of  inflammation  is  the  most  common,

and  begins  seldom  before  the  seventh  day  of  the  pucrperium— most  often  from  the 
tenth  to  the  twentieth  day.  Frequently  there  is  a  little  pain  in  one  portion  of  the 
breast,  marked  while  nursing,  and  occasionally  slight  fever— 99°  F.— for  a  day  or 
two  preceding  the  outbreak.  This  is  manifested  by  a  more  or  less  severe  chill  and 
fever.  The  temperature  may  reach  106°  F.  and  l)e  accompanied  by  delirium,  Ijut 
usually  does  not  go  over  103°  F.,  and  the  febrile  symptoms  are  moderate.  Pain  in 
the  breast  is  the  rule,  and  over  the  lol)e  affected  redness  and  tenderness  are  found, 
and  usually  the  nipple  will  show  a  fissure,  the  site  of  entrance  of  the  infection. 
Any  quadrant  of  the  organ  may  be  inflamed,  though  usually  the  outer  half, 
and  here  one  or  more  large  lumps  may  be  palpated.  In  one  case  the  spot  of 
redness  and  tenderness  was  not  larger  than  a  nickel,  yet  the  woman's  temperature 
was  105°  F.  Under  ajipropriate  treatment  the  temperature  and  pain  ^sAibside 
within  thirty-six  hours  unless  the  other  breast  is  also  affected,  as  in  Fig.  779.     If 


894  PATHOLOGY  OF  THE  PUERPERIUM 

the  fever  continues  for  more  than  forty-eight  hours,  suppuration  rarely  fails  to 
appear.  Then  the  temperature  becomes  remittent,  chills  occur,  the  portion  of  the 
breast  affected  swells  up,  containing  a  large,  hard  mass.  At  one  spot  it  softens,  and 
redness  of  the  skin,  with  a  bluish  tinge,  indicates  where  the  pus  is  coming  to  the 
surface.  Unless  promptly  operated,  successive  lobes  are  involved  until  the  whole 
breast  is  riddled  with  abscesses.  These  must  all  be  opened  and  drained,  healing 
often  requiring  weeks  or  even  many  months.  Naturally,  in  these  cases  the  cellular 
tissue  is  also  involved.  Sometimes  the  acute  symptoms  subside  and  the  accoucheur 
believes  the  process  is  at  an  end,  but  a  few  weeks  later  fever  begins  again  and  the 
breast  suppurates,  or  pus  is  evacuated  through  the  nipple. 

In  the  cellulitic  or  phlegmonous  variety  the  infection  travels  into  the  gland  from

a  fissure  and  along  the  connective-tissue  septa,  and  redness,  fan-shaped,  spreading 
from  the  crack,  may  be  seen  around  the  nipple.  If  the  deeper  lymphatics  are 
involved,  the  case  resembles  one  of  deep  cellulitis  anywhere,  wdth  bra^^^ly  swelling  of 
the  skin.  Usually  the  streptococcus  is  here  concerned, — at  least  some  heterogeneous 
bacterium, — and  such  cases  are  more  frequent  in  general  hospital  practice.  The 
fever,  though  at  first  less  intense,  keeps  up  longer,  and  the  pulse  more  quickly  feels 
the  effect  of  the  toxemia.  Erysipelas  has  been  observed,  and  even  a  pan-mastitis. 
Suppuration  is  much  more  common  in  this  form  of  mastitis,  but  often,  too,  the 
breast  shows  only  a  firm  infiltrate,  which  may  be  absorbed  in  from  six  to  twelve 
days.  After  three  or  four  days  it  is  possible  to  foresee  which  termination  is  to  oc- 
cur.    The  axillary  lymphatic  glands  may  be  enlarged. 

In  the  submammary  abscesses,  which  Billroth  believed  were  due  to  sui)pura-

tion  of  deep-seated  mammary  gland  tissue,  the  pus  collects  behind  the  gland,  which 
then  seems  to  float  on  a  cushion,  and  edema  appears  at  the  periphery.  The  general 
symptoms  are  most  threatening  in  this  form  of  infection — indeed,  miless  promptly 
evacuated,  the  pus  may  ])urrow  far  and  the  patient  die  of  bacteremia. 

Treatment.— At  the  beginning  it  is  not  always  possible  to  determine  whether  the  infection 
IS  of  the  parenchymatous  or  the  celluUtic  variety,  but  the  treatment  is  the  same  for  both.  The 
following  practice  has  been  found  very  successful  l)y  the  author:  (1)  Hemove  the  infant  from  the 
breast,  and  from  both  breasts  if  the  symptoms  are  not  very  mild;  massage  and  pumping  the  breast 
are  forbidden;  (2)  administer  a  brisk  saline  cathartic;  (3)  apply  a  tight  brea.st-binder;  (4j  put 
two  or  three  ice-bags  on  each  breast.  The  nipple  is  surrounded  by  a  ring  of  cotton;  a  layer  of 
the  same  is  laid  between  the  two  breasts;  a  rolled  towel  is  placed  to  support  the  organ  from  the 
axillary  side,  and  the  breasts,  lifted  up,  are  tightly  bandaged.  The  ice-bags  mast  keep  the 
breasts  cool,  but  the  nurse  is  instructed  to  watch  the  skin  for  signs  of  freezing,  which,  by  the  way, 
I  have  never  seen  with  this  treatment.    After  the  temperature  has  been  normal  for  twelve  hours|

the  bags  are  removed  one  by  one,  and  in  twenty-four  hours  the  child  may  be  put  back  to  the 
breast.     This  treatment  is  more  succe.s.-<ful  in  the  parenchymatous  forms  than  the  cellulitic. 

If  an  abscess  forms,  it  must  be  incised  as  soon  as  diagnosed.  If  the  attendant  is  certain  that 
suppuration  ha.s  begun,  the  ice  is  replaced  with  a  hot  wet  boric  dressing.  In  opening  lireast 
absce-sses  the  operator  should  make  a  long  incision  in  a  hne  radiating  from  the  nipple,  and  with 
the  finger  he  searches  out  all  the  pockets  of  the  particular  lobe  involved.  If  more  than  one  lobe 
is  suppurating,  an  incision  is  made  into  each  one  and  pus  pockets  cleared,  the  septa  between  them 
broken  down,  and  adequate  drainage  provided  by  tubes  and  gauze.  This  procedure  is  a  for- 
midable operation,  and  is  often  followed  by  cliill,  fever,  and  aggravation  of  the  symptoms,  some- 
times with  septic  eruptions,  but  these  subside  within  thirty-six  hours,  and  the  patient  goes  on  to 
recovery.  Occasionally  new  portions  of  the  breast  break  down,  forming  secondarj-  abscesses 
which  may  riddle  the  breasts,  and  these  maj-  protract  the  heahng  for  montiis.  I  have  noticed 
that  if  such  pockets  are  not  immediately  opened,  but  left  for  a  few  days  and  then  incised  l)roadl}- 
and  the  cavity  rubbed  briskly  with  the  finger  (gloved),  a  sort  of  auto-inoculation  or  vaccination 
is  made,  which  has  a  good  influence  on  the  whole  gland.  The  sinuses  drain  better  under  a  wet 
dres.sing,  which  is  at  first  rencwetl  thrice  daily;  later,  less  often.  Attention  must  be  given  to 
building  up  the  general  health,  which  is  likely  to  suffer  from  the  profuse  suppuration  and  pro- 
longed illness.     The  patient  is  to  be  gotten  out  of  bed  and  out-of-<loors  as  soon  as  po.>^sible. 

When  the  sinuses  are  very  persistent  and  new  foci  of  .suppuration  constantly  appear,  vaccine 
treatment  is  to  be  tried.  It  is  best  to  get  the  bacterium,  usually  the  Staphylococcus  albus.  from 
the  patient  and  make  an  autogenous  vaccine,  giving  first  5,000,000,  then  in  a  few  daj-s  25,000,000 
or  50,000,000,  if  necessary. 

The  author  has  used  the  Bier  treatment  oa  several  cases  of  mastitis,  and  does  not  find  that 


896  PATHOLOGY  OF  THE  PUERPERIUM 

it  materially  shortens  the  length  of  the  suppuration,  nor  does  it  enable  one  to  dispense  with  large 
incisions. 

In  the  cellulitic  variety  of  mastitis,  if  diagnosed  early,  a  hot,  wet  boric  dressing  covering  a 
large  part  of  the  chest  would  be  better  than  the  ice.  Incision  is  to  be  delayed  until  definite  sup- 
puration is  discovered.  Surgeons  are  divided  as  to  the  propriety  of  incising  colluhtic  infiltrates 
early.  Judging  from  my  experience  in  treating  cellulitis  in  the  pelvis,  I  would  wait  for  actual 
pus-formation.  Submammary  abscess  is  to  be  opened  at  once  by  broad  incisions  at  the  periphery 
of  the  gland. 

SUNDRY  COMPLICATIONS  OF  THE  PUERPERIUM 

Naturally,  a  puerpera  may  suffer  from  anj'  of  the  diseases  she  would  contract  under  other 
conditions,  without  any  bearing  on  the  puerperal  state.     A  few  of  these  deserve  special  mention. 

Fever  from  Emotional  Influences. — See  p.  867. 

Fever  from  Constipation. — ^^'ithout  doubt,  overloading  of  the  bowels  may  cause  fever 
during  the  puerperiimi,  but  such  cases  mvist  be  extremely  rare.  Almost  invariably  a  temperature 
that  at  first  was  ascribed  to  stercorrhemia  is  found  later  to  be  due  to  an  infection  in  the  pelvis  or 
the  breasts.  The  cUagnosis  must  be  made  by  exclusion,  which  is  admittedly  a  precarious  method. 
The  therapeutic  test — subsidence  of  the  fever  following  brisk  catharsis — is  ab.solutelj'  unreliable, 
because— (1)  Energetic  action  of  the  bowels  may  affect  the  uterus  and  stimulate  it  to  contraction, 
expelling  from  its  cavity  clots,  locliia,  and  detritus;  (2)  the  peh-ic  circulation  is  hastened  by  the 
cathartic,  an  action  most  exliibited  by  aloes,  and  the  relief  of  an  overloaded  rectum  improves 
the  currents  of  the  blood  and  h'mph  in  the  pelvis;  (3)  some  cathartics  produce  leukocytosis, 
which  aids  in  repelhng  infections;  (4)  a  full  rectum  may  cause  lochiometra  or  stasis  of  locliia  in 
the  vagina — its  emptying  and  the  bearing-down  efforts  of  defecation  relieve  the  stasis.  There- 
fore, if  the  fever  subsides  after  the  bowels  are  emptied,  the  case  may  have  been  one  of  infection, 
and  not  of  absorption  of  toxins  from  the  intestinal  tract,  as  supposed. 

Budin,  in  1892,  called  attention  to  febrile  stercorrhemia,  and  Kiistner,  Oui,  Lavergne,  and 
others  have  reported  typical  cases.  Fever,  headache,  anorexia,  sometimes  nausea  and  abdominal 
pain,  are  the  sj'mptoms.  The  tongue  is  heavilj^  coated,  the  breath  fetid,  the  skin  muddy  or  pasty, 
the  belly  distended  with  gas  or  doughy  to  the  touch  over  the  large  bowel,  and  often  tender.  The 
lochia,  usually  normal,  may  have  a  fecal  odor  (colon  bacillus),  but  the  uterus  and  adnexa  are 
normal.  Brisk  catharsis  and  enemata  produce  copious  fetid  evacuations,  after  which  the  symptoms 
subside.  When  the  rectum  is  packed  with  hardened  feces,  it  may  be  necessary  to  inject  a  soft- 
ening enema  (1  di'am  inspissated  ox-gall  triturated  in  1  ounce  of  glycerin,  to  which  are  added  2 
pints  of  water).  After  this  has  acted  for  an  hour  the  softened  mass  may  be  removed  by  the  gloved 
fingers,  aided  by  rectal  hrigation  of  saline  solution. 

Tape-worms  have  often  been  expelled  during  the  puerperium.  Fever  has  occasionally  been 
ascribed  to  them,  but  in  two  of  my  cases  they  existed  without  causing  temperature.  The  treat- 
ment is  the  usual  one,  but  the  child  is  to  be  kept  away  from  the  breast  for  the  two  days  required 
for  the  action  of  anthelminthic  remedies. 

Tympany  and  Ileus. — Tympam^  occurring  after  delivery  seldom  becomes  obstinate  or  very 
marked,  and  gives  no  concern  if  the  bowels  are  moving  and  the  general  condition  is  not  affected. 
If  the  distention  does  not  cjuickh'  subside  under  the  usual  treatment  (a  cathartic,  carminative 
enemata,  a  o-grain  asafetida  pill  three  times  dady),  the  possibility  of  a  serious  affection  should 
be  entertained,  and  a  careful  search  made  for  a  cause. 

Obstruction  of  the  bowels  may  be  due  to  kinking  from  adhesions,  the  sequelse  of  former 
operations  or  inflammations,  and  requires  the  usual  treatment.  In  one  case  I  found  that  a  retro- 
verted  puerperal  uterus  compressed  the  rectum.  After  raising  this  up  with  one  finger  in  the 
bowel  the  obstruction  was  relieved. 

Ileus  after  cesarean  section  is  the  same  as  that  met  so  often  by  sm-geons,  but  it  may  follow^ 
operative  deUveries  from  below — hebosteotomy,  even  natural  deliveries.  Sometimes  an  acute 
dilatation  of  the  stomach  is  at  fault,  and  again  paralysis  of  the  small  intestine  or  occlusion  of  the 
large  bowel.  Bruising  the  bowel  when  the  uterus  is  massaged,  kinking  from  adhesions,  compres- 
sion of  the  bowel  by  the  retroverted  uterus  in  the  pelvis,  thrombosis  of  one  of  the  celiac  or  mesen- 
teric arteries,  an  unrecognized  rupture  of  the  uterus,  rupture  of  a  pus-sac,  with  beginning  peritonitis 
— all  these  may  cause  excessive  tympany  and  ileus  postpartum.  Infection  of  the  peritoneum 
from  some  cause  must  always  fu-st  be  thought  of  in  these  cases.  The  diagnosis  is  the  most  impor- 
tant part  of  the  treatment.  If  it  is  decided  not  to  open  the  abdomen,  the  following  measures  may 
be  tried:  repeated  enemata,  of  which  the  milk  and  molasses  combination,  1  pint  of  each,  is  the 
best;  this  may  be  given  with  the  patient  inverted;  turning  the  patient  on  her  stomach;  elevation 
of  the  head  and  shoulders;  ."j-grain  asafetida  pills  tlirice  daily;  washing  out  of  tlie  stomach  (very 
useful);  eserin,  ^V  grain  liypodermically  evin-y  four  hours  for  four  doses;  hormonal  hypoder- 
mically;  puncture  of  the  gut  with  a  fine  needle — while  said  to  be  safe,  to  be  used  only  as  a  last 
resort.     The  same  is  said  of  making  an  intestinal  fistida. 

Fissures  in  ano  are  a  not  infreciuent  complication  of  the  late  puerperiimi.  Inspection 
readily  reveals  them,  and  stretching  of  the  sphincter  witli  a  speculum  and  a  few  a])plications  of 
10  per  cent,  silver  nitrate  solution  to  the  cracks  as  readily  cure  them.  Oil  enemata  and  free 
action  of  the  bowels  strengtlien  the  cure. 

Difficulty  of  Urination. — This  subject  has  already  been  touched  upon  (p.  322).  and  here  need 
be  mentioned  only  the  ovcrfilHng  of  the  l)ladder,  with  dril)l)hng  (incontinentia  paradoxa);  over- 
filling with  only  partial  emptying  of  the  bladder  (evidenced  bj'  pain  in  the  belly,  a  displaced  uterus, 
a  soft  tumor  above  the  pubis,  sometimes  tympany,  and  lochiostasis  and  fever);  and  the  dribbling 
of  urine  which  comes  through  a  vesical  fistula  or  paralysis  of  the  sphincter  vesica;. 

Exhaustion  psychoses  may  oc-cur  after  prolonged  and  arduous  labors  in  weakened  individuals. 


PART  III 
OPERATIVE  OBSTETRICS 


CHAPTER  LXVIII 
GENERAL  CONSIDERATIONS 

During  pregnancy  and  labor  the  accoucheur's  duty  to  his  patient  is  both 
prophylactic  and  remedial.  After  providing  for  the  gravida  as  described  in  the 
Hj'giene  of  Pregnane}',  p.  225,  his  course  is  one  of  watchful  expectancy. 
He  simply  studies  the  processes  of  nature  and  determines  when,  where,  and 
how  he  may  be  of  assistance,  but  he  must  always  bear  this  in  mind,  that  he 
never  can  be  of  ''assistance"  unless  something  in  the  course  of  pregnancy, 
labor,  or  the  puerperium  goes  wTong.  Under  such  circumstances  he  makes  up 
his  mind  that  he  must  interfere.  This  is  the  first ;  second,  he  studies  what 
he  must  do,  and  third,  when  he  should  do  it.  That  something  in  the  course  of 
pregnancy,  labor,  or  the  puerperium  which  commands  interference,  or  any  mode  of 
treatment,  is  called  an  '^  indication."  The  many  features  of  each  obstetric  case 
are  the  factors  which  determine  or  specify  the  nature  of  the  procedure  to  be  insti- 
tuted. We  call  them  ^"conditions."  A  condition,  therefore,  is  a  prerequisite  which 
must  be  fulfilled  before  the  procedure  demanded  by  the  indication  maj'  be  carried 
out.  The  study  of  the  case,  and  the  determination  that  there  is  a  reason  for  the 
adoption  of  a  particular  line  of  treatment,  we  call  "placing  the  indication,"  and 
this  requires  very  delicate  balancing  of  all  the  conditions.  Speaking  broadly,  all 
indications  for  interference  lie  in  the  presence  of  immediate  or  prospective  danger 
to  mother  or  child.  The  conditions  will  be  found  in  the  state  of  the  mother  at  the 
time  of  the  intended  treatment.  Only  when  the  conditions  necessary  for  carrying 
out  the  procedure  are  present  may  we  act,  but  the  indication  may  be  so  strong  that 
we  have  to  "force  the  condition."  For  example,  a  woman  has  eclampsia.  The 
indication  is  to  empty  the  uterus,  but  the  cervix  is  tightly  closed.  A  condition  for 
rapid  delivery  is  an  open  cervix;  therefore  we  must  first  open  the  cervix,  or  choose 
an  operation  which  has  not  this  binding  condition.  A  condition  which  absolutely 
prohibits  a  given  line  of  treatment  we  call  a  "contraindication." 

Selection  of  Operation. — This  will  depend  on  the  indications  and  conditions, 
but  often  there  are  other  considerations,  as  the  skill  of  the  operator,  the  environ- 
ment of  the  patient,  the  religion  of  the  family,  the  desires  of  tlie  parents.  An 
unskilful  practitioner,  miless  he  can  obtain  competent  counsel,  should  always  do 
that  operation  which  promises  the  greatest  safety  to  the  mother.  If  the  patient 
is  amid  bad  surroundings,  it  may  ])e  necessary-  to  sacrifice  the  child,  while  if  she  were 
in  a  good  maternity,  cesarean  section  would  save  both.  A  Catholic  family  does  not 
permit  craniotomy  on  the  living  chikl,  and  a  husband  may  absolutely  demand  that 
his  ^nfe  be  sul)jected  to  no  added  risks  for  the  sake  of  the  child.  These  points  will 
again  be  considered. 

Diagnosis. — Before  every  obstetric  procedure  the  accoucheur  must  have  made 
a  careful  general  examination.  He  must  know  the  exact  condition  of  the  kidneys, 
heart,  lungs,  thyroid,  blood,  etc.  Just  before  an  operative  delivery,  with  the  pa- 
57  ^  897

tient  onatablc  and  perhaps  anesthetized,  the  examination  of  the  local  conditions — 
presentation,  position,  attitude  of  the  child,  the  state  of  the  cervix,  etc.,  must  be 
repeated,  because  things  may  have  changed  in  the  time  intervening,  or  the  first 
diagnosis  may  have  been  wrong.  If  the  local  findings  are  different  from  what  was 
expected,  the  original  plan  of  procedure  must  be  dropped  or  altered.  Any  other 
course  which  might  be  taken  to  save  the  accoucheur  trouble  and  mortification 
usually  results  in  more  of  each  for  him,  and  endangers  the  patient.  It  may  be 
wisest  to  put  the  woman.  Ijack  in  bed  and  select  an  entirely  different  line  of  treat- 
ment. 

After  the  diagnosis  is  made  and  proved,  the  operator  may  well  rehearse  the  steps 
of  the  operation  in  his  mind  beforehand,  and  take  cognizance  of  the  various  com- 
plications which  are  likely  to  arise.  If  he  will  construct  a  mental  picture  of  the 
conditions  before  him  and  then  do  the  operation,  as  it  were,  "in  the  air,"  before 
the  patient,  he  will  be  surprised  how  much  the  correct  procedure  is  facilitated. 

Assistants. — For  good  surgical  operating  at  least  three  assistants  are  required — 
an  anesthetist,  a  first  assistant,  and  a  nurse  to  hand  instruments.  Most  surgeons 
demand  more  help  than  this,  but  most  accoucheurs  are  satisfied  with  even  less. 
Why  an  accoucheur  should,  voluntarily,  deny  himself,  the  patient,  and  the  baby 
the  benefits  of  sufficient  help  is  incomprehensible.  In  private  practice  it  is  often 
impossible  to  obtain  more  than  one  assistant  to  give  the  anesthetic,  and  the  nurse 
must  do  all  the  rest  of  the  work.  Sometimes  there  is  no  nurse  even,  and  the 
accoucheur  has  himself  to  give  the  anesthetic  while  operating.  If  the  general 
practitioner  would  equal  the  work  done  in  the  maternity  hospitals,  he  must  educate 
the  public  to  allow  him  sufficient  help,  and  it  can  be  done  easier  than  he  thinks. 
Circumstances  are  very  unusual  where  another  physician,  one  or  two  medical 
students,  or  one  or  two  extra  nurses  are  not  obtainable.  It  is  unsafe  to  trust  the 
husband  to  help  or  to  hold  a  light.     He  may  collapse;    further,  it  is  cruel. 

Examination  of  the  Patient  after  Delivery.— I  have  made  it  an  invariable  rule 
to  examine  the  parturient  canal  from  the  fundus  to  the  vulva  and  the  adjacent 
viscera  and  pelvis  after  every  operative  delivery.  The  hand  is  inserted  into  the 
uterus,  palpates  the  placental  site,  removing  adherent  placental  fragments,  decidual 
debris,  membranes,  and  blood-clots,  then  encircles  the  lower  uterine  segment  three 
times,  going  from  right  to  left,  and  three  times  from  left  to  right, — this  in  order  to 
discover  a  slit-like  injury, — then  the  vagina  likewise,  and  then  the  vulva.  Tears 
of  all  degrees  are  carefully  searched  out.  The  pubic  joint  is  palpated,  the  bladder 
catheterized,  and  finally,  after  all  repairs  have  been  made  and  just  before  applying 
the  vulvar  dressing,  the  finger  is  passed  into  the  rectum  to  find  out  if  any  stitches 
have  been  put  through  it  or  if  it  is  otherwise  injured.  The  accoucheur  must  know 
and  record  the  location  and  extent  of  all  the  puerperal  wounds.  Only  by  such 
routine,  thorough,  painstaking  examination  may  a  rupture  of  the  uterus  and  other 
injuries  be  discovered,  and  I  cannot  insist  too  strongly  on  the  adoption  of  this  recom- 
mendation. Under  the  protection  of  sterile  rubber  gloves  and  thorough  antisepsis 
of  the  vulva  and  vagina  the  procedure  is  safe. 

After  operative  deliveries  the  child,  too,  requires  a  careful  gentle  examination 
of  the  head  and  all  its  members.  It  may  not  be  so  easy  to  discover  a  skull  fracture 
or  a  broken  clavicle  as  we  would  like  it  to  be. 

Reflection. — A  most  profitable  procedure  after  it  is  over  is  for  the  accoucheur 
to  review  all  the  details  of  his  case  and  what  he  has  done,  considering  the  result, 
and  examine  himself  to  see  if  his  judgment  has  been  good  and  his  technic  perfect; 
then  to  decide  what  he  would  do  in  a  similar  case  or  if  the  same  woman  became 
pregnant  again.  All  these  im])ressions  should  be  written  on  the  history  card. 
They  will  be  invaluable  for  future  reference  and  also  for  individual  improvement. 

Anesthetic. — The  reader  is  referred  to  the  chapter  on  Anesthesia  in  Normal 
Labor.     For  many  operations  an  anesthetic  is  not  necessary,  though  occasionally 


GENERAL   CONSIDERATIONS  899 

it  is  demanded  by  a  very  apprehensive  patient.  Such  are  packing  the  cervix  to 
induce  aljortion  or  premature  labor,  the  appHcation  of  the  metreurynter,  rupture 
of  the  mem})ranes,  insertion  of  bougies,  vaginal,  even  uterine,  tamponade.  I 
seldom  use  anesthesia  for  ordinary  perineorrhaphies,  but  if  the  tear  is  extensive  or 
the  patient  too  nervous,  it  is  neces.sary.  Curetage  in  abortions  with  the  finger 
or  the  curet,  and  manual  removal  of  the  placenta,  in  about  half  of  the  cases  may  be 
done  without  narcosis,  and  I  have  several  times  applied  the  forceps  without  it, 
thus  getting  the  assistance  of  the  labor  pains  in  the  delivery.  Occasionally,  for  a 
short  operation,  the  patient  can  be  put  in  a  semi-conscious  condition  and  kept 
there  by  an  expert  anesthetist;  this  is  the  first  stage  of  anesthesia,  and  precedes 
the  one  of 'excitement,  and  I  have  often  suggested  analgesia  to  the  patient,  either 
by  words  or  by  giving  whiffs  of  ether.  Increasing  experience  teaches  me  to  avoid 
anesthetics  wherever  possible.  Two  fatal  cases  of  hepatic  cytolysis  and  three 
cases  of  icterus  after  chloroform,  four  serious  ether  pneumonias,  and  several  bad 
bronchitis  cases  have  warned  to  care,  not  to  mention  prolonged  nausea  and  vomiting 
and  the  pain  caused  by  them.  These  three  discomforts  often  are  worse  than  the 
pain  relieved  by  the  drug.  Narcotic  drugs  also  have  a  bad  influence  on  the  child, 
and  I  am  convinced  that  many  of  the  deaths  ascribed  to  asphyxia  are  in  reality 
anesthetic  deaths. 

Ether  by  the  open  or  drop  method  is  my  choice  of  anesthetic  when  one  must  be 
used,  and  many  surgeons  are  coming  to  believe  that  it  is,  after  all,  the  safest.  For 
versions  and  extractions  the  narcosis  must  be  deep  enough  to  abolish  reflexes  and 
quiet  all  muscular  action,  thus  to  allow  the  operator  to  do  his  work  deliberately. 
After  the  child  is  born  the  mask  is  to  be  removed,  and  often  the  operation  may  be 
completed  without  giving  any  more  of  the  drug,  or  it  may  be  resumed  for  the 
cleaning  out  of  the  uterus  or  the  perineorrhaphy. 

In  cases  of  marked  anemia,  in  eclampsia,  in  other  toxicoses,  \\dth  goiter,  in 
Basedow's  disease,  and  in  heart,  lung,  and  kidney  diseases,  in  women  with  marked 
kyphoscoliosis  or  great  abdominal  distention,  all  anesthetics  are  dangerous,  and 
may  be  used  only  with  the  greatest  circumspection.  I  employ  a  specialist  on  anes- 
thesia wherever  possible.  The  practice  of  some  accoucheurs,  unavoidable  in  some 
instances,  of  giving  the  anesthetic  and  performing  the  operation  at  the  same  time 
is  to  be  condemned.  It  is  unfair  alike  to  the  patient,  the  babj',  the  doctor,  and  the 
art  of  obstetrics. 

Nitrous  oxid  and  oxygen  anesthesia  may  be  used  for  brief  operations  not 
concerned  with  delivery,  such  as  curetage  in  abortions,  perineorrhaphies,  and 
manual  removal  of  the  placenta.  IVIy  experience  has  been  that  these  operations 
are  rendered  unusually  bloody  by  the  gas.  For  operative  deliveries  I  do  not  recom- 
mend these  gases  because  of  the  initial  anaerosis  and  asphyxia  which  affect  the  child 
unfavorably. 

Local  anesthetics  are  rarely  usable  in  obstetric  practice,  and  medullary  anes- 
thesia, I  believe,  should  be  discarded  entirely.  Several  cases  of  cesarean  section 
under  local  anesthesia  have  been  reported.  Injection  of  novocain  solution  into  the 
regions  of  the  pudic  nerves,  through  the  vagina,  is  recommended  by  ]\Iuller. 

Preparations. — The  manner  of  preparation  for  operative  deliv'ery  in  a  private  home  will  be 
described  ;us  briefly  as  possible.  In  nuitornities  the  technic  is  identical  \\-ith  that  of  major  opera- 
tions, plus  preparation  for  the  complicities  presented  by  the  sudden  accidents  of  delivery  and  the 
attention  retiuired  by  the  baby.  The  principles  of  the  practice  of  asepsis  and  antisepsis  are  the 
same  as  in  the  practice  of  surgery,  and  have  already  been  considered.  Fig.  780  shows  the  oper- 
ator's ch-ess.  If  there  is  no  one  pVesent  capable  of  resuscitating  the  child,  the  head-piece  must  be 
arranged  to  allow  the  operator  to  use  his  mouth  for  insufflation  of  air  per  catheter  to  the  baby. 
Fig.  330  on  p.  318  shows  the  dress  of  the  patient  during  delivery.  When  the  woman  is  put  ou 
the  operating-table,  the  exposed  area  of  mons,  vulva,  perineum,  to  the  edges  of  the  leggings,  is 
again  disinfected  with  lysol  solution,  and  1:1.")00  bichlorid,  a  pair  of  sterile  leggings  put  on,  and  a 
sterile  towel  laid  over  the  belly.  This  towel  is  frequently  clianged  during  the  operation,  and  the 
skin  and  vulva  are  fretiuently  drenched  with  an  antiseptic  solution.  Even  though  once  sterilized, 
the  leggings  are  not  touched  by  the  operator.     If  he  does  so  inadvertently,  he  washes  his  hands

in  ihe  solutions.     The  assistants  liolding  the  legs  wear  gloves.     It'  ealled  upon  to  hold  instruments, 
etc.,  they  too  wash  in  the  antiseptic  solutions. 

In  private  home  practice,  although  all  the.  sheets,  towels,  leggings,  etc.,  are  sterilized  when 
they  have  l)een  put  on  the  patient,  the  accoucheur  should  touch  them  as  little  as  possible.  Only 
the  area  immediately  around  the  ridva,  which  has  been  disinfected  and  is  frcqueidly  drenched  with 
antiseptic  solxdions,  and  the  towel  over  the  abdomen,  arc  to  be  cotisidered  .sterile,  and  may  be  touched 
by  the  accoucheur.  If  he  will  practise  this  principle  as  a  habit,  he  will  be  abl(>  to  carry  out  the 
most  complicated  obstetric  proc(>dures  amid  the  most  discouraging  surroundings,  with  greatest 
safety.  Our  operating-rooms  err  in  this  regard.  The  sterile  field  of  openition  is  made  too  large. 
The  absolute  sterility  of  the  inunediate  site  of  the  operation  and  of  the  instruments,  sponges,  etc., 
which  come  into  it  is  the  bacteriologic  laboratory  idea  of  asepsis,  and,  to  my  mind,  the  correct 
one — certainly  for  private  practice.     If  everything  else  is  considered  infected,  it  is  not  so  hard  for 

the  operator  and  his  assistants  to  preserve  the  asepsis  of  the 
/^^*^  actual  field  of  operation. 

f^^^jL  During  the  coiu-sc  of  the  operation,  esj)ecially  if  pro- 

c^^^Bh  longed,  the  vulva  and  thighs  are  freciuently  swabbed  with 

V^^^S  antiseptic  solutions — 1:1500  l)ichlorid  and  1  per  cent,  lysol 

B       jV  solution.     If  feces  escape  from  the  anus,  they  are  received 

r       ai  with  the  greatest  care  in  pledgets  soaked  in  bichlorid  solution. 

If  the  rectvnn  is  very  full,  it  may  be  advisable  to  wash  it 
clean  with  sterilized  saline  solution.  To  try  to  keep  fecal 
matter  away  from  the  field  by  holding  a  towel  or  swab  over 
the  anus  is  fatuous — the  feces  are  simply  smeared  all  over 
the  perineum  by  such  procedures.  It  is  best  to  see  what 
becomes  of  the  evacuations,  and  disinfect  the  anus  contin- 
uously, taking  extra  care  during  all  manipvdations  not  to 
pass  the  hands,  instruments,  or  gauze  near  the  source  of 
infection.  After  delivery,  if  much  use  has  i)een  made  of 
strong  antiseptics,  it  is  a  good  plan  to  wash  the  parts  with 
sterile  water,  to  prevent  an  eczema. 

Aseptic  technic  is  not  the  final  word  in  the  prevention 
of  infection.  Good  operative  technic,  the  preservation  of 
the  woman's  immunities,  the  prevention  of  shock  and  hemor- 
rhage, pi'oper  selection  of  operation,  etc.,  contribute  as  much 
to  success. 

Preparation  of  Patient  for  Operative  Delivery. 

— If  the  woman  has  not  been  prepared  as  already 
described  on  p.  275,  she  is  gotten  ready  for  operation 
just  before  the  anesthetic  is  started.  The  operator 
first  sterilizes  his  hands.  The  vulva  is  shaved, 
scru])bed  with  soap  and  water,  the  smegma  under 
the  hood  of  the  clitoris  removed  with  oil  or  vaselin, 
and  the  parts  thoroughly  washed  with  both  lysol 
and  l;)ichlorid  solutions.  The  vagina,  too,  is  mopped 
out  with  lysol  solution,  care  being  taken  to  rub 
lightly  and  not  destroy  the  epithelium  too  much. 
In  order  to  prevent  hairs  and  wash-water  dripping 
into  the  vagina  dtiring  the  shaving  and  washing,  a 
large  swab  soaked  in  antiseptic  solution  is  packed 
into  the  introitus.  After  everything  else  is  disin- 
fected, the  swab  is  removed  and  this  part  and  the 
vagina  are  attended  to.  If  the  patient  had  already 
Ijeen  prepared  for  normal  labor,  all  that  is  needful 
is  a  thorough  washing  with  Ihe  antiseptic  solutions. 

Painting  the  parts  with  tincture  of  iodin  is  practised  by  some  operators.     In  all 

cases  the  accoucheur  must  be  sure  that  the  bladder  is  empty. 

Arrangement  of  the  Room. — Fig.  781  is  a  diagram  of  a  room  in  a  ]irivalc  home, 

and  Fig.  782  shows  the  arrangement  of  tables,  etc. — a  plan  which  is  in  daily  use 

by  the  author. 

Provision  for  good  light  is  essential.     An  acetylene  ])icycle  lamp  or  ihe  lamps 

from  an  automobile  I  have  many  times  found  useful. 

The  kitchen  or  library  table  makes  an  excellent  operating-table,  and  shoukl 

always  be  used.     It  is  unfair  to  the  woman,  the  baby,  and  the  doctor  to  operate

to  reason  that  better  work  can  be  done  on  the  table,  and,  further,  the  dignity  of  the 
specialty  of  obstetrics  is  concerned.  Even  the  specially  constructed  obstetric  beds 
do  not  possess  the  advantages  of  a  table.

Posture  of  Patient.— In  America  and  in  Continental  countries  the  parturient 
is  always  placed  on  the  back  for  operative  delivery  or  other  obstetric  operation. 


GENERAL   CONSIDERATIONS 


903 


England  alone  uses  the  side  position,  but  less  now  than  formerly.  Kerr  uses  it 
only  for  low  forceps  operations.  Fig.  783  shows  the  most  convenient  posture. 
In  cases  of  shoulder  presentation,  or  in  breech,  when  it  is  desired  to  get  the  present- 
ing part  away  from  the  inlet,  the  head  of  the  table  may  be  lowered,  as  described  by 


Fig.  785. — Author's  Oper.vtion  Telescope. 


Richardson,  a  comljination  of  lithotomy  and  Trendelenburg  positions.  In  some 
cases  it  is  necessary  to  turn  the  woman  on  her  side  for  a  few  minutes- — for  example, 
to  grasp  the  anterior  foot  in  back-posterior  shoulder  presentations.  The  woman's 
leg  then  is  simply  lifted  over  the  head  of  the  operator,  and  replaced  after  he  has

grasped  the  foot.  A  few  operations — replacement  of  cord,  disentanglement  of 
locked  twins — are  performed  with  the  patient  in  the  knee-chest  position,  and  I 
have  operated  on  several  women,  pulseless  from  hemorrhage,  with  the  body  sus- 
pended head  down  from  the  shoulders  of  two  assistants.  The  ease  with  which 
version  can  be  done  in  this  posture  is  surprising.     Walcher's  position  (Fig.  655)  is

used  to  aid  the  passage  of  the  head  through  the  inlet,  and  the  exaggerated  Hthotomy 
when  it  is  passing  the  bony  outlet  (Fig.  495,  p.  571). 

Instrumentarium. — In  city  and  town  practice  it  is  not  reciuired  to  take  to  the 
labor  case  a  couii)li'le  obstetric  outfit.  Tlie  satchel  shown  on  p.  270  meets  all  the 
demands  of  the  usual  labor  and  the  operations  most  commonly  performed.  If  a 
high  forceps  or  a  version,  or  the  care  of  placenta  praevia,  eclampsia,  etc.,  is  to  be 
attempted,  or  if  the  woman  lives  far  from  the  operator's  base  of  supplies,  a  complete 
o])stetric  armamentarium  must  he  at  hand,  and  such  an  outfit,  if  the  accoucheur 
wishes  to  be  abreast  of  the  times  and  give  his  patient  the  benefit  of  his  art,  must  ])e 
an  extensive  one.  Fig.  785  shows  the  author's  obstetric  bag  for  operative  cases, 
and  Fig.  786,  the  portable  sterilizer.     The  instruments  are  packed  in  the  pan  of  the

sterilizer;  the  other  articles  are  arranged,  without  any  especial  order,  in  the  upper 
compartment  of  the  telescope.  I  have  found  it  impracticable  to  have  special  cases 
and  compartments  made  for  each  article — the  satchel  is  complicated  enough  without 
them.  The  instruments  may  l^e  divided  into  sets  for  perineorrhaphy,  for  forceps, 
for  craniotomy,  and  wrapped  in  separate  towels.

for  same,  1  long  curved  needle,  1  raspatorium,  and  1  flat  director. 

Pre\nous  to  operation  the  instruments  recjuired  are  boiled  for  ten  minutes  in 
a  1  per  cent,  soda  or  borax  solution  in  a  covered  vessel.  This  absolutely  sterilizes 
them,  and  the  operator  serves  himself  with  them  from  the  open  trays  on  the  table 
beside  him. 

Provision  for  Complications. — It  is  wise  at  all  times  to  make  preparations  to 
combat  postpartum  liemorrhage  and  asphA-xia  of  the  child.  For  the  former,  the 
nurse  will  have  the  douche-bag  sterilized,  filled,  and  covered,  ready  for  instant  use, 
and  the  accoucheur  will  have  a  supply  of  sterile  gauze  and  instruments  for  lacera- 
tions and  for  packing.  For  the  child,  an  appropriate  place  is  pro\'ided  to  lay  it, 
with  the  tracheal  catheters,  warm-water  bags,  towels,  and  a  hot  bath  close  at  hand. 

Just  before  the  operation  the  accoucheur  surv^eys  the  room  to  see  if  everything 
is  in  readiness — as  a  general  surveys  the  field  of  battle. 

Care  of  Feces  Issuing  from  the  Anus. — This  is  a  very  unwelcome  complication 
of  any  obstetric  operation,  because  it  requires  the  most  constant  watchfulness  and 
the  greatest  dexterity  to  avoid  transporting  the  infectious  material  into  the  geni- 
tals. Sometimes  the  feces  contain  only  saprophj-tic  and  harmless  organisms — a 
fact  which  is  proved  by  the  rarity  of  serious  infections,  when  we  know  how  often 


906 


OPERATIVE    OBSTETRICS 


fecal  matter  is  brought  into  the  vagina,  hut  occasionally  the  Streptococcus  pyogenes 
and  the  gas  bacillus  in  virulent  condition  exist,  and  fatalities  in  considerable  number 
are  on  record.  IMeasures  should  have  been  instituted  beforehand  to  provide  for 
such  a  contingency,  that  is,  a  cathartic  administered  early  in  labor,  and  an  enema 
given  to  wash  the  lower  bowel  clean.  If  labor  lasts  several  days,  these  are  repeated 
— taking  Care  that  it  be  not  too  shortly  before  delivery. 

If  the  bowels  move  as  the  operation  is  begun,  the  rectum  should  be  emptied 
by  squeezing  out  its  contents  from  the  vagina,  using  two  fingers.  I  prefer  not  to 
irrigate  the  rectum  with  sterile  water  unless  the  head  is  well  do'OTi  in  the  pelvis  and 
blocks  the  further  do^^'npour  of  fecal  matter.  Hard  feces  are  easier  to  manage  than 
spattering  liquids.     After  the  rectum  is  emptied  a  pack  of  sterile  gauze  may  be

inserted  temporarily,  but  only  until  the  presenting  part  comes  down  onto  the  per- 
ineum. Then  it  is  to  be  removed,  otherwise  the  bowel  will  be  injured  during 
delivery.  For  the  same  reason  a  suture  around  the  anus  is  hazardous.  The  anal 
region  must  be  constantly  inspected  during  the  delivery,  and,  as  feces  exudes,  it  is 
carefully  received  in  wet  antiseptic  gauze  or  cotton,  the  parts  then  being  liberally 
drenched  with  1 :  1500  bichlorid  and  1  per  cent,  lysol  solutions.  Whenever  the 
hand  is  inserted  into  the  vagina,  it  is  passed  from  above  under  the  pubic  arch, 
the  possibility  of  contamination  being  always  kept  in  mind  (Fig.  788).  To  try 
to  preserve  asepsis  by  fastening  a  towel  or  pad  over  the  anus  is  illusory — the  feces 
being  thus  simply  plastered  all  over  the  perineal  region  from  the  inside  of  the 
cloth,  even  damming  back  up  into  the  vulva. 


CHAPTER  LXIX 
PREPARATORY  OBSTETRIC  OPERATIONS 

Opening  the  Cervix. — The  state  of  the  cervix  is  a  condition  which  governs  the 
indications  of  most  obstetric  operations.  In  eclampsia,  placenta  preevia,  and  all 
diseases  demanding  immediate  emptying  of  the  uterus  the  state  of  the  cervix  has 
a  guiding  influence  in  the  choice  of  procedure.     We  have  many  methods  of  gaining

access  to  the  uterus— some  slow,  some  rapid.  The  slow  ones  are  those  which  call 
the  uterus  into  action  to  aid  in  the  dilatation,  and  the  process  resembles  natural 
labor  more  closely.  Packing  the  cervix  and  metreurysis  are  slow  operations,  but 
in  some  of  the  more  rapid  ones  uterine  action  also  aids  the  process  in  a  marked 
degree,  as  in  manual  dilatation  and  the  employment  of  the  Bossi  dilator.  The 
following  operations  are  done  to  open  the  cervix:  Packing  the  cervix  and  lower 
uterine  segment -^-ith  gauze;  manual  or  digital  dilatation;  metreurysis;  mechanical

The  tube  has  a  lumen  |  inch  across.     Gauze  3  inches  wide  or  a  knit  bandage  is  used  for  packing.     It  is  sterilized

the  case  and  the  nature  of  the  complication  demanding  the  interference;    (3)  on 
the  skill  of  the  operator;    (4)  on  the  environment  of  the  patient. 

It  is  of  greatest  importance  to  distinguish  between  a  cervix  that  is  already

Catching  the  end  of  the  gauze  strip  from  the  bottle,  which  is  held  near  the  vulva,  by  means  of  the  trident  plunger, 
the  gauze  is  pushed  the  whole  length  of  the  tube.  Now,  under  the  guidance  of  the  two  fingers,  placed  in  or  against  the 
cervix,  the  tube  is  in.serted  into  the  lower  part  of  the  uterus.  With  short  in-and-out  strokes  of  the  plunger  the  gauze 
is  deposited  above  and  in  the  cervical  canal,  taking  care  to  distribute  it  evenly  and  not  to  rupture  the  membranes. 
This  is  easily  accomplished  by  moving  the  end  of  the  tube  in  circles  and  retracting  it  as  the  cavity  fills  up.  From  three 
to  five  yards  may  be  inserted.     In  most  cases  the  vagina  need  not  be  plugged.     It  is  occasionally  needed  in  abortions. 


effaced  or  obliterated  and  one  that  has  not  been  at  all  taken  up,  and  also  to  know 
how  far  the  process  has  advanced.  During  the  effacement  and  dilatation  of  the  cer- 
vix the  pelvic  connective  tissue  is  drawii  up  out  of  the  pelvis;  the  bladder  is  drawn 
up,  and  its  attachment  to  the  cervix  loosened  and  displaced  upward,  the  ureters  going

with  it;  the  peritoneum  is  elevated;  the  broad  hgamcnts  unfolded;  and  the  large 
vessels  at  the  sides  of  the  uterus  raised  up  and  retracted,  sometimes  even  above  the 
brim.  This  means  that  these  important  structures  are  removed  from  the  pelvis, 
where  they  are  subject  to  injury  from  below  (Figs.  789  and  790).  In  primipara? 
this  unfolding  of  the  cervix  may  occur  to  some  extent  in  the  last  weeks  of  pregnancy, 
and  is  sometimes  accompanied  by  fugitive  labor  pains,  and  this  is  also  true  of  multi- 
para, in  whom  there  is  an  additional  softness  of  the  tissues.  Artificial  opening  of 
the  cervical  canal  is  easiest  in  the  last  weeks  of  pregnancy,  but  even  then  there  is

danger  of  deep  lacerations,  and  the  more  nature  has  opened  the  cervix,  the  less  the 
accoucheur  has  to  do. 

Packing  the  cervix  is  shown  in  Fig.  792.  It  may  be  employed  to  start  labor 
(Hofmeier,  1888),  to  induce  abortion  (Wyder,  1888),  to  soften  and  dilate  the 
cervix  preparatory  to  the  insertion  of  a  colpeur\iiter,  and  to  stimulate  flagging 
labor-pains  in  the  first  stage.  Ordinarily,  if  not  already  present,  pains  come  on 
within  eight  hours,  but  sometimes  not  for  twenty-four,  when  the  first  packing  is 
removed  and  another  inserted,  if  needed,  or  other  methods  adopted.     This  simple 


910 


OPERATIVE    OBSTETRICS 


operation  may  be  done  when  the  cervix  is  closed.  Anesthesia  is  rarely  required. 
I  have  never  found  it  necessary  to  use  a  metal  dilator  after  the  sixth  month  to  procure 
enough  dilatation  to  pass  the  tube,  of  which  there  are  several  sizes,  with  gauze  to 
fit.  It  may  be  done  safely  at  home.  It  is  not  useful  in  urgent  cases  nor  in  placenta 
prsevia.  The  dangers  are  infection  (which  can  be  avoided),  rupture  of  the  mem- 
branes, which  may  allow  prolapse  of  the  cord,  separation  of  the  edge  of  the  placenta 
if  situated  near  the  internal  os,  and  air-embolism.  The  latter  may  be  avoided  by 
holding  the  labia  spread  apart  by  the  fingers  and  the  instrument,  by  packing  slowly, 
and  having  the  shoulders  of  the  patient  raised.  Separation  of  the  edge  of  a  lowly 
inserted  placenta  occurred  once  in  the  very  many  cases  in  which  I  have  thus  packed. 
It  was  evidenced  by  a  slight  flow  of  pure  blood.  I  put  no  more  gauze  into  the 
uterus,  but  packed  the  cervix  tightly,  and  the  result  was  good.  Rupture  of  the 
membranes  occurred  several  times  without  bad  results — indeed,  labor  seemed  has- 
tened.    Vaginal  tamponade  was  described  under  Abortion  {q.  v.). 

Manual  Dilatation  of  the  Cervix. — This  is  the  oldest  method  of  enlarging  the

canal,  and  is  spoken  of  in  Hippocrates'  writings.  It  is  the  method  most  naturally 
adopted,  but  the  ancients  also  possessed  pronged  instruments  operated  by  screws. 
Pare,  in  the  forced  operative  delivery,  which  he  so  much  practised,  and  to  which 
his  pupil,  Cruillemeau,  gave  the  name  "accouchement  force,"  began  with  digital 
dilatation  of  the  cervix.  First  one  and  then  two  fingers  are  insinuated  through  the  os. 
The  two  fingers  may  be  then  spread  by  one  or  two  fingers  of  the  other  hand  forced 
between  them  like  a  wedge  (Fig.  793).  After  the  tips  of  four  fingers  are  introduced 
they  are  placed  back  to  back,  the  knuckles  acting  like  a  double  fulcrum,  and  the 
cervical  ring  is  thus  expanded.  This  is  similar  to  the  methods  devised  by  Bonnaire 
and  Edgar.  P.  Harris  inserts  the  whole  hand  into  the  vagina,  and  the  cervix  is 
dilated  by  the  insinuation  into  it  of,  successively,  one  finger,  the  thumb  and  one 
finger,  then  two,  then  three  and  four,  and  finally  the  hand,  the  thumb  being  given 
a  motion  of  extension,  the  fingers  one  of  flexion.  The  only  advantage  this  method 
has  over  the  others  is  that  the  hand,  being  in  the  vagina,  is  not  so  easily  contami- 
nated by  feces  issuing  from  the  anus,  but,  by  raising  the  hands  toward  the  pubis 
in  the  performance  of  the  operation  illustrated  above,  this  danger  may  be  avoided. 


PREPARATORY   OBSTETRIC    OPERATIONS

It  is  essential  to  procure  complete  opening  of  the  canal,  otherwise  the  delivery 
of  the  child  which  follows  may  be  difficult  or  impossible,  and  during  the  fruitless 
attempts  at  extraction  the  undilated  uterus  may  rupture  or  the  child  die  or  be  se- 
verely injured.  The  conditions  for  manual  dilatation  of  the  cervix  are:  The  cervix 
must  be  effaced,  or  very  nearly  so;  the  pelvis  normal;  the  child  normal  in  size, 
and  the  presentation  and  position  favorable  or  corrigible.  The  placenta  may  not 
be  prsevia.  The  vagina,  too,  must  be  dilatable,  or  is  to  be  enlarged  by  episiotomy. 
Unless  performed  under  these  conditions,  the  operation  is  dangerous  and  may  fail 
of  its  purpose.  It  requires  from  one  to  three  hours,  and  is  often  painfully  tiring  to 
the  fingers  and  hands.  It  is  invariably  attended  by  lacerations  of  the  cervix,  and 
these  tears  are  often  deep,  sometimes  even  of  the  importance  of  a  rupture  of  the

uterus,  opening  the  peritoneal  cavity,  causing  death  from  hemorrhage  or  from 
infection.  In  multiparse  the  lacerations  are  usually  somewhat  less  extensive. 
In  all  cases  the  cervix  is  bruised  and  battered,  and  infection,  even  in  the  hands  of 
the  cleanest  obstetrician,  is  sometimes  unavoidable.  In  truly  exceptional  cases 
the  cervix  is  so  soft  that  it  may,  within  fifteen  to  thirty  minutes,  be  dilated  large 
enough  for  safe  delivery. 

Metreurysis. — Historic. — In  1851  Carl  Braun  invented  the  oolpeuryntor,  a  ru])hor  balloon  to

decomposed  In  1862  Tarnier  invented  the  "  dilatateur  intrauterin,"  a  soft-rubber  bag  or  condom 
on  the  end  of  a  male  catheter.  Barnes,  in  1862,  introduced  the  soft-rubber  fiddle-shaped  bags, 
which  are  not  used  any  more.  In  1888  Champetier  de  Ribes  recommended  a  large,  cone-shaped, 
inelastic  bag,  and  since  then,  among  the  numerous  modifications  that  have  been  proposed,  the 
use  of  cloth  bags,  rendered  impermeable  bv  rubber,  has  already  superseded  the  old  colpeurynter 
of  Braun.     Schauta,  in  1SS3,  published  the  use  of  the  bag  in  the  uterus,  as  practised  in  Spaeth  s

olinio.  Miiurer,  in  1SS7,  introduced  constant  traction  on  the  l)ag  as  a  means  to  liastcn  its  action. 
In  1907  Stowe  invented  a  bag  shaped  Uke  the  Voorhees  bag,  but  with  a  tube  h-acUng  through  its 
center,  through  which  sterile  sah  sohition  can  be  injected  into  the  uterus  to  replace  lost  liquor 
amnii,  an  idea  suggested  several  years  before  by  Bauer  to  the  Berlin  Medical  Society.  Of  all  the 
bags  on  the  market.  1  have  found  tho.^e  of  Voorhees,  in  four  sizes,  and  the  large  ones  of  the  same 
shape  sold  in  Europe  under  the  name  of  Miiller,  the  best,  l^ut  on  some  occasions  I  still  us(>  the 
Carl  Braun  colpeurynter.  Since  the  bag  is  usually  placetl  in  the  uterus,  the  name  hystreurynter 
or  metreurynter  is  better.  The  bags  are  filled  with  water  and  boiled  in  plain  water  for  thirty 
minutes,  then  laid  in  1  per  cent,  lysol  solution,  with  which  they  are  to  be  filled  for  application. 

The  method  of  appHcation  of  the  hydrostatic  bag  has  been  minutely  described 
on  p.  455,  in  the  Treatment  of  Phicenta  Prsevia  (q.  v.).  Some  operators  prefer 
to  pass  the  bag  by  sight  (Fig.  796),  beheving  that  thus  it  is  easier  to  avoid  carrying 
infection  from  the  vagina  into  the  uterus.  The  perineum  is  retracted  by  a  speculum, 
the  cervix  is  steadied  by  a  ring  forceps,  and  the  folded  bag  is  gently  insinuated  into 


Fig.  700. — Passing  CoLPErRVNTEH  nr  Sight. 


and  through  the  canal,  in  the  direction  of  one  of  the  sacro-iliac  joints,  taking  due 
notice  of  the  curves  of  the  canal.  Force  may  not  be  used,  and  it  is  best,  in  the 
absence  of  special  indication,  to  preserve  the  membranes.  Such  special  indications 
are  eclampsia,  in  which  it  has  been  noticed  that  the  convulsions  often  cease  after 
the  liquor  amnii  has  been  let  off,  polyhydramnion,  twins,  and  other  conditions  of 
overfilling  of  the  uterus,  and  placenta  prsevia,  in  order  to  place  the  bag  on  top  of 
the  placenta. 

If  time  is  no  object,  traction  is  not  api)lied,  but  if  the  pains  are  slow  in  coming, 
a  weight  of  one  or  two  pounds  may  be  attached  to  the  tube.  After  the  first  bag  is 
expelled  a  larger  one  may  be  applied,  the  membranes  punctured,  or  the  labor  left 
to  nature,  depending  on  the  exigencies  of  the  case. 

The  action  of  the  metreurynter  is  three-fold:  First,  it  mechanically  dilates  the 
cervix  from  aljove  downward  like  a  fluitl  wedge,  in  which  resp(H't  it  closely  reseml:)les 
the  bag  of  waters;  second,  by  its  presence  and  by  the  dilatation  of  the  uterus  which 
its  increased  volume  causes,  but  particularly  by  pressure  on  the  retrocervical 


PREPARATORY   OBSTETRIC    OPERATIONS  913 

ganglion,  the  uterus  is  stimulated  to  action,  and  strong  pains  are  usually  soon 
inaugurated.  Third,  it  may  be  used  as  a  tampon,  as  in  cases  of  placenta  pra?via, 
etc.  The  selection  of  the  bag  will  depend  on  the  object  sought,  and  if  rapid  action 
is  desired,  the  inelastic  bag  with  traction  \vi\\  more  quickly  evoke  pains  and  dilate 
the  uterus  than  the  soft-rubber  colpeur^-nter,  which,  under  traction,  is  likely  to 
pull  out  into  a  sausage  shape  and  slip  through  the  poorly  dilated  cervix.  If  it  is 
simply  desired  to  evoke  pains,  as  in  the  induction  of  labor,  either  bag  may  be  used 
without  traction,  or  with  a  minimum  amount  of  it.  As  a  tampon  in  the  vagina,  the 
soft  colpeur\Titer  is  preferred;  in  the  treatment  of  placenta  prsevia,  the  Yoorhees' 
conic  inelastic  bag.  Early  in  pregnancy,  and  in  the  late  months,  just  to  inaugu- 
rate uterine  action,  a  small-sized  bag  is  employed. 

Indications. — Metreurysis  is  very  useful  for  the  induction  of  premature  labor 
W'here  great  urgency  is  not  present,  though  sometimes,  if  traction  is  put  on  the  tube 
andtheparts  are  not  too  rigid, thepainsstartup, and  they,  together  withthe  mechani- 
cal dilatation,  open  the  uterus  in  a  few  hours.  Whenever  there  is  an  indication  to 
hasten  delivery  in  the  interests  of  the  mother  or  child,  the  bag  may  be  used,  and  to 
prepare  the  cervix  or  the  vagina  for  rapid  delivery,  as  in  breech,  shoulder,  or  face 
presentation,  or  in  the  presence  of  threatening  complications,  they  are  often  inval- 
uable. In  stenosis  of  the  cervix  the  bags  may  be  useful,  but  they  require  the  aid 
of  the  pains  to  soften  the  parts.  A  sluggish  uterus  may  be  stimulated  by  the  met- 
reurynter, but  it  is  \tise  to  find  out  the  cause  of  the  weak  pains — rigidity  of  the  cervix, 
abnormal  adherence  of  the  membranes,  overdistention  of  the  uterus,  pendulous 
belly,  low  placenta — all  these  may  require  other  treatment.  In  cases  of  dry  labor 
the  bags  deserve  more  general  application,  since  they  replace  the  bag  of  waters  to  a 
considerable  extent.  In  shoulder  presentation,  to  preserve  what  is  left  of  the  liquor 
amnii  and  to  keep  the  presenting  part  from  impaction  in  the  pelvis,  the  met- 
reurynter should  be  applied  and  complete  dilatation  awaited.  In  contracted  pelvis, 
where  spontaneous  delivery  is  to  be  expected,  a  bag  is  to  be  applied  if  the  membranes 
rupture  prematurely.  Generally  speaking,  metreurysis  is  useful  when  the  bag  of 
waters  ruptures  before  complete  dilatation  has  been  effected.  In  prolapse  of  the 
cord  the  hj'streurynter  is  of  great  value.  Perhaps  the  most  valuable  function  of 
the  metreurynter  is  as  a  plug  in  cases  of  placenta  praevia.  While  properly  not 
belonging  here,  it  may  be  mentioned  that  the  colpeurynter  is  useful, — placed  in  the 
vagina,  to  prepare  the  vagina  and  pelvic  floor  for  rapid  delivery,  as  in  breech  pres- 
entation, forceps,  version,  and  extraction;  to  overcome  rigidity  of  the  soft  parts; 
to  stimulate  pains;  and,  during  pregnancy,  to  lift  up  a  retroflexed  uterus,  to  raise  a 
uterus  that  may  be  causing  hj-peremesis,  and  in  the  treatment  of  pyelo-ureteritis. 

Conditions. — The  cervix  must  be  open  enough  to  insert  the  size  of  bag  desired. 
Rarely  is  it  necessary  to  use  metal  dilators  first.  Packing  the  cervix  with  gauze 
for  twelve  hours  usually  suffices  to  render  it  soft  and  chlatable.  Cervical  carcinoma 
and  threatened  uterine  rupture  contraindicate  the  operation.  In  the  presence  of 
vaginal  infection  some  other  plan  should  be  selected,  if  possible,  such  as  puncture 
of  meml)ranes,  vaginal  cesarean  section,  even  the  Porro  operation. 

Dangers  and  Disadvantages. — In  a  few  cases  the  uterus  does  not  respond,  the 
bag  is  not  expelled,  and  traction,  within  the  limits  of  safety,  does  not  open  the  cervix. 
Sometimes  traction  brings  one  bag  after  another  through,  but  the  uterine  action 
does  not  come  into  play  and  the  cervix  closes  up  again.  Several  cases  are  recorded 
Avhere  pregnancy  continued.  Oftener  the  repeated  manipulations,  which  in  some 
cases  may  extend  over  a  period  of  five  or  more  days,  causes  fever  (infection),  and 
then,  unless  the  pains  come  on  strongly,  a  formidable  condition  is  presented  for 
treatment.     Such  torpor  of  the  uterus  is  rare. 

The  metreurynter  may  displace  the  presenting  part,  but  this  usually  is  not 
undesirable,  since  often  version  is  in  contemplation.  Prolapse  of  the  cord  is  a  real 
danger.     In  spite  of  close  watching  and  care  this  happened  in  two  of  my  cases,  and 


914 


OPERATIVE    OBSTETRICS 


in  one  I  lost  the  infant  because  of  it.  The  danger  of  inflection  is  nil — with  proper 
precautions.  Three  cases,  one  fatal,  of  air  embolism  from  bursting  of  the  bag  are 
reported.  A  liquid  should  have  been  used  for  filling.  Rupture  of  the  uterus  has 
l)een  reported  in  11  instances,  but  in  several  of  them  the  extraction  of  the  child 
through  an  insufficiently  dilated  passage  was  probably  the  real  cause.  In  the 
others  excessive  softness  of  the  cervix  was  a  factor — placenta  prsevia,  nephritis. 
In  my  case,  a  primipara  aged  thirty-eight  with  placenta  prsevia,  the  bag  evoked 
such  tumultuous  pains  that  it  ruptured  the  uterus,  the  woman  dying  of  internal 
hemorrhage.  If  too  much  traction  is  put  on  the  bag,  the  uterus 
acts  too  violently,  and  such  danger  is  real.  If  too  much  fluid  is 
injected  into  the  bag,  the  uterus  is  overdistended,  as  in  polyhy- 
dramnion,  and  the  uterine  action  is  usually  weak,  but  sometimes 
the  opposite  is  true.  A  large  experience  with  the  bags,  however, 
together  with  study  of  the  voluminous  literature  on  the  subject, 
convinces  me  that  most  of  the  disadvantages  may  be  overcome  by 
proper  technic  and  by  watching  the  effects,  not  leaving  the  patient 
to  ignorant  attendants.  They  are,  indeed,  a  very  valuable,  indis- 
pensable addition  to  our  obstetric  resources.  Since  the  rubber 
deteriorates  with  time,  the  bags  are  to  be  kept  dry  in  an  ordinary 
paste-board  box,  and  thus  preserved,  will  last  one  or  two  years. 

Machine  Dilatation. — Tertullian,  in  the  second  century  after  Christ, 
mentions  pronged  uterine  dilators,  and  they  played  a  more  or  less  prominent 
part  in  gynecologj'  and  obstetrics  since.  Levret  (1760)  opposed  tlieir  general 
use.  Goodell's  dilator  is  the  type  of  the  instrument  used  by  gyniatrists  and 
in  the  treatment  of  early  abortions.  In  18S8  Bossi  invented  a  branched 
dilator  for  the  partiu-ient  cervix,  which  had  great  vogue  in  the  years  1902 
to  1906,  but  now  is  almost  generally  discarded  (Fig.  797).  The  principle 
of  the  instrument  is  irrational.  Constant  elastic  distraction  of  the  cerA'ix 
was  invented  by  Tarnier  in  his  three-branched,  glove-stretcher-like,  "ecar- 
teur  uterin,"  forced  apart  by  elastic  bands  around  the  handles.  Bossi  re- 
placed the  i^ands  with  a  powerful  screw  and  added  a  scale  to  show  the 
amount  of  separation  of  the  blades. 

In  all  the  cases  in  which  I  have  used  the  instrument,  ten  in  number, 
lacerations  of  greater  or  less  degree  resulted,  and  Bossi's  directions  were  care- 
fully followed.  I  use  it  only  on  women  at  or  near  term,  when  the  cervix 
is  completely  effaced  and  is  very  soft  and  dilatable,  conditions  where  tlie 
hands  would  render  equally  good  service.  American  authorities  do  not 
recommend  such  instruments.  Literature  and  history  of  all  dilating 
methods  are  to  be  found  in  the  articles  of  Hartz  and  Lewis  and  DeLee. 

Incisions  in  the  Cervix. — Hysterostornoto7)iy . — The  first 
records  of  cervix  incisions  to  aid  delivery  are  from  the  eigh- 
teenth century,  but  probably  they  were  made  earlier. 
Baudelocque,  about  1790,  condemned  them;  Simp- 
son used  them  in  cases  of  carcinoma;  Godemer  (1841), 
in  eclampsia;  Skutsch,  in  1887,  to  save  the  baby; 
l)ut  Diihrssen,  in  1890,  show^ed  their  value  so  con- 
clusively that  they  are  often  termed  "Dtihrssen's 
incisions."  The  field  of  usefulness  of  this  operation 
is  very  limited,  because  the  incisions  are  safe  only  after  complete  effacement  of  the 
cervix.  Reference  to  Figs.  789  and  790  will  show  that  a  cut  made  before  the  Ijlood- 
vessels  are  retracted  exposes  them  to  great  danger — indeed,  several  deaths  have 
occurred  from  hemorrhage,  and  if  the  tissues  are  incised  before  obliteration  of  the 
cervix  is  complete,  the  wounds  are  likely  to  tear  further  during  the  extraction  and 
open  up  the  broad  ligaments,  even  the  peritoneal  cavity.  The  ancients  made 
multiple  small  cuts  in  stellate  fashion,  but  Diihrssen  made  deep  lateral  cuts,  and  if 
these  were  not  sufficient,  posterior  and  anterior  incisions  also.  Other  operators 
make  the  cuts  in  the  oblique  diameters,  two  or  four  as  needed,  which  method  is 
preferable.     It  is  essential  that  the  greatest  deliberation  l)e  practised  in  the  sub- 


FiG.    797.-

Dilator.

915 


sequent  extraction  of  the  child  to  prevent  the  lacerations  from  extending — an 
accident  which  has  happened  in  the  hands  of  the  world's  best  accoucheurs.  The 
preparations  for  the  operation  are  the  same  as  for  any  major  ol)stetric  procedure, 
because  sometimes  a  severe  hemorrhage  must  l)e  faced,  and  afterward  the  wounds 
are  to  be  repaired.  The  indications  are  found  in  those  complications  bringing 
danger  to  mother  or  child,  when  the  cervix  is  obliterated,  only  the  thin  partition 
between  the  dilated  lower  uterine  segment  and  the  vagina  ))eing  left  to  overcome. 
It  is  a  common  operation  before  the  application  of  forceps  in  occipitoposterior 
positions  in  primipara?,  or  in  other  operative  deliveries  when  the  cervix  is  not  open 
enough.  Rigid  cervix  scars,  conglutination,  etc.,  are  occasional  indications.  The 
condition  which  must  be  insisted  on  is  complete  effacement  of  the  cervix.     Placenta

Under  wide  exposure  of  the  field  by  broad  specula  the  cervix  is  grjjsped  and  cut  between  two  eight-inch  forceps,  which

prsevia  is  a  contraindication.  Most  so-called  manual  and  instrumental  dilatations 
of  the  cervix  are  in  reality  bilateral  incisions  or  tears,  but  made  with  lilunt  instru- 
ments. 

Accouchement  Force. — This  operation  was  introduced  by  Pare,  given  the  name 
by  Guillemeau,  his  pupil,  but,  owing  to  its  great  maternal  (sepsis  and  hemorrhage) 
and  fetal  (asphyxia)  mortality,  was  employed  only  in  the  gravest  emergencies. 
Under  the  protection  of  asepsis  and  antisepsis  it  was  revived,  but  is  now  rapidly 
falling  into  disuse  because  of  the  almost  invarialile  severe  injuries  inflicted  on  the 
mother,  the  frequent  hemorrhage  and  deaths  caused,  and  the  paucity  of  fetal  lives 
saved.  The  original  conception  of  the  operation  was  rapid  dilatation  of  the  cervix 
by  the  hands,  version,  and  forced  extraction  of  the  child.  Recently  the  term  has 
been  used  to  apply  to  any  one  of  several  methods  of  rapid  delivery  from  below. 


916 


OPERATIVE    OBSTETRICS 


While  admitting  that  a  few  cases  occur  where  it  is  not  extra-hazardous  to  dilate  the 
cervix  and  extract,  according  to  the  original  formula,  these  are  so  few  and  the  dan- 
gers of  the  others  so  great  that  the  author  would  advise  dropping  l)oth  the  term  and 
the  operation  altogether  from  our  ol)stetric  surgery,  a  condition  which,  to  judge 
from  present  obstetric  literature,  will  soon  be  present.  As  a  substitute  for  this 
brutal  and  unsurgical  operation  the  metreurjTiter,  in  cases  of  not  great  urgency,  and 
vaginal  or  abdominal  cesarean  section  in  the  others,  are  suggested. 

Mention  may  be  made,  for  the  sake  of  c(mdemning  the  procedure,  of  the  oper- 
ation of  using  the  body  of  the  child  as  a  dilator  of  the  parturient  canal.  Unless 
the  infant  is  dead,  and  excepting  a  few  cases  of  placenta  prsevia,  such  a  method  is 
inadvisable. 

Vaginal  cesarean  section,  or  colpohysterotomy,  is  an  operation  devised  by 
A.  Diihrssen,  of  Berlin,  April  1,  1895.     Acconci,  of  Italy,  devised  a  similar  operation, 


-Instruments  for  Vaginal  Cesarean  Section. 
Short  broad  specula,  3  sizes,  also  1  long  narrow;  scalpel,  3  scissors,  1  of  which  is  long;  8  G-inch,  and  6  S-inch 
artery  clamps;  2  ring,  2  double  vulsellum,  and  2  bullet  forceps;  3  dissecting  forceps;  long  and  short  needle-holders;  6 
needles;  silkworm  gut  and  catgut;  uterine  packing  forceps;  silver  female  catheter;  gauze  for  packing;  obstetric 
forceps;  tracheal  catheters;  if  vaginal  hysterectomy  is  to  follow,  add  2  Deschamps  needles  and  double  the  number  of 
long  artery  clamps. 


but  Diihrssen  ("Der  vaginale  Kaiserschnitt,"  Berlin,  1904)  conclusively  proves  his 
priority.  The  term  vaginal  cesarean  section,  used  in  the  eighteenth  century  for 
cervical  incisions,  was  considered  Ijy  Baudelocciue  unsuitable.  Although  Diihrssen's 
operation  is  a  formidable  one,  deserving  the  name  he  chose  for  it,  the  terms  vaginal 
hysterotomy  or  colpohysterotomy  might  supplant  it. 

Preparations. — These  are  the  same  as  for  any  major  obstetric  operation.  An  anesthetist, 
two  assistants,  and  a  nurse  are  needed  if  fiootl  work  is  to  l)e  done. 

A  table,  the  hthotomy  position,  and  good  horizontal  light  are  essential.  The  operation 
has  been  succes.sfulh'  done  imder  the  exigencies  of  practice  in  a  home,  but  with  increased  technical 
difficulties. 

The  Operation. — If  the  parturient  is  clo.se  to  the  end  of  pregnancy  and  primijiai'ous,  it  is 
be.st  to  make  a  deep  unilateral  episiotomy — on  that  side  to  which  the  occiput  i)()ints  if  forceps  are 
to  be  used;  on  the  opposite  si<le,  if  version  is  to  be  performed.  This  will  prevent  laceration  of  the 
perineum  during  the  subsctiuent  delivery.  If  the  episiotomy  wound  l)l('eds  too  freely,  it  may  be 
sewn  up  temporarily,  the  line  of  suture  being  at  a  right  angle  to  th(>  line  of  incision.  Diihrssen 
insisted  on  the  necessity,  in  case  the  child  is  at  full  term,  of  making  both  anterior  and  posterior 
cervical  incisions.  Bumm  finds  the  anterior  incision,  if  extended,  gives  sufficient  space.  My  ex- 
perience accords  with  Diihrssen's.     The  cer\ix  nnist  be  in  the  nuHlian  line.     It  is  often  twisted  by

After  the  vagina  has  been  reflected  off  the  base  of  the  bladder,  the  latter  is  pushed  upward,  off 
the  anterior  cervical  wall  (Fig.  SOlj,  using  the  finger  covered  with  gauze.     At  the  same  time

the  cervix  is  partly  freed  from  the  bases  of  the  broad  ligaments  at  the  sides,  but  care  is  required 
here,  as  large  veins  may  be  encountered.  Now  the  cervix  is  grasped  by  two  vulsellum  forceps 
and  split  medially  (Fig.  802)  up  to  the  internal  os.  Fig.  803  shows  this  section  matle  aiul  the  bag

Now  the  medial  uterine  incision  is  continued  upward  (Fig.  804),  the  vulsellum  forceps  being  placed 
on  successively  higher  portions  of  the  cervix  and  lower  uterine  segment,  and  pulling  them  down  into 
the  bite  of  the  scis.sors.  Care  is  to  be  exercised  to  keep  in  the  median  line  and  to  avoid  injuring 
the  peritoneum.  This  is  pushed  off  the  lower  uterine  segment  before  the  advancing  scissors  by 
means  of  the  finger.

For  a  child  weighing  about  3  or  3^2  pounds,  an  anterior  incision  10  cm.  in  length  usually 
suffices.  One  may  test  the  size  of  the  opening  by  passing  through  it  the  fist,  made  about  the 
size  of  the  baby's  head,  by  holding  in  it  a  large  ballof  cotton.     If  more  space  is  needed,  the  ante-

Grasping  the  cervix  with  bullet  forceps,  it  is  split  to  the  vaginal  reflection,  then  the  perito-

uterine  segment  is  divided  as  high  as  needful.     Delivery  is  now  accomplished  by  forceps  or  by

version  and  extraction,  according  to  preference — I  prefer  forceps.  If  lal)or  pains  are  present, 
hemorrhage  is  not  usurJly  profuse,  but  if  it  is,  manual  removal  of  tlu;  placenta  and  uterine 
tamponade  are  rapidly  performed,  and  ergot  given  hypodermically,  or  adrenalin  (1:10,000) 
injected  into  the  cut  edges  of  the  uterine  muscle.  A  careful  examination  of  the  parturient  tract  is 
made  to  determine  the  extent  of  the  wounds.     Now  the  wounds  are  sutured  (Fig.  806).     By  trac-

tion  on  the  silk  loop.s  or  vulsella,  placed  on  the  uterine  edges,  the  uppermost  angle  of  the 
wound  is  readily  drawn  into  view,  which  may  be  aided  by  a  narrow  speculum  placed  so  as  to 
retract  the  bladder.  A  continuous  suture  of  No.  2  plain  catgut,  taking  in  the  mucosa  and 
part  of  the  muscle,  is  rapidly  put  in,  care  being  observed  not  to  include  the  uterine  packing, 
and  over  this  a  second  layer  is  placed,  after  which  the  vagina  is  closed  with  a  running  suture 
of  chromic  gut.  A  strip  of  gauze  may  be  left  to  drain  the  large  subperitoneal  wound  for  twenty- 
four  hours.  If  the  posterior  wall  lias  been  divided,  this  is  sutured  first,  with  a  running  through- 
and-through  catgut  suture,  tied  on  the  interior  of  the  cervix.  Finally,  the  perineum  is  repaired. 
The  operation  requires  from  eight  to  twenty  minutes  for  the  delivery  of  the  child,  and  from  twenty 
to  forty  minutes  to  repair  the  incisions.  If,  as  with  cancer,  the  uterus  is  to  be  extirpated,  the 
anterior  and  posterior  incisions  are  prolonged  until  the  uterus  is  bisected,  and  the  broad  ligaments 
are  clamped  and  tied,  each  half  being  removed  after  the  methofl  of  P.  Miiller. 

Dangers. — Injury  of  the  bladder  and  ureters  may  be  avoided  by  proper  technic,  by  going 
slowly  without  attempts  at  spectacular  operating.  In  pushing  the  bladder  off  the  cervix  it  must 
be  borne  in  mind  that,  a^  labor  progresses,  the  bladder  is  drawn  up,  and  usually  to  the  right  side.

In  breech  and  shoulder  presentations  the  bladder  is  more  central.  One  of  my  cases  whose  oper- 
ation was  entirely  uncomphcated  returned  after  six  years  with  a  displaced  and  kinked  left  ureter 
which  causes  intermittent  hvdronephrosis.  Hemorrhage  is  usually  not  marked  if  the  uterus  is 
di\-ided  cleanly  in  the  middle  line,  if  the  tissues  at  the  side  are  spared,  and  the  cuts  do  not  tear 
further,  which  thev  will  not  do  if  properly  placed  at  first.  In  one  case  the  tissues  were  so  friable 
that  the  traction  ligatures  and  vulsella  pulled  out,  and  hemorrhage  was  so  profuse  that  the 
va<^inal  route  had  to  be  abandoned.  After  the  delivery,  packing  the  uterus  will  stop  hemorrhage. 
Pulling  down  the  uterus  stronglv  also  has  a  good  influence.  There  is  no  reason  why  Momburg  s 
constrictor  may  not  be  applied  if  needed  at  this  stage.  In  one  case  the  broad  ligaments  and  pelvic 
connective  ti*«ue  were  so  edematoas  that  the  cer\-ix  could  not  be  drawn  down  for  incision,  and  ab- 
dominal cesarean  section  was  indicated.  To  gain  access  to  the  cervix  when  it  is  high  up  Duhrssen 
advised  a  deep  paravaginal  perineal  incision,  or  deep  episiotomy,  and  also  lately,  what  seems  to 
be  a  real  improvement  in  this  operation,  the  metreurynter,  by  means  of  which  the  cervix  is  pulled 
down  and  on  which  it  is  incised.  When  the  fully  distended  colpeurynter  can  come  through  the 
incision  the  child  can  be  easily  delivered.  Should  the  bladder  be  opened,  it  is  to  be  sutured  after 
dehverv  and  a  permanent  catheter  inserted.     If  the  peritoneum  is  torn,  it  is  sutured  at  once. 


920  OPERATIVE    OBSTETRICS 

In  l)oth  instances  drainage  from  below  is  indieated.     Hiipturo  of  the  vagina  occurred  in  two  of 
my  causes,  threatening  hemorrhage  from  the  liases  of  the  broad  ligaments  in  three. 

Subsequent  pregnancies  anil  lai)or  in  three  of  my  cases  wer(>  entirely  uneventful,  and  many 
such  are  reported,  so  that  there  need  be  but  little  fear  that  the  uterus  will  rupture,  but  in  several 
instances  the  wound  did  not  heal  perfectly,  leaving  an  everted  (>roded  cervix. 

Indicotions. — "\^'^len  the  cervix  is  closed  and  an  indication  arises  for  rai)id 
delivery,  and,  second,  when  the  cervix  is  diseased  and  nature  is  unable  to  overcome 
the  obstruction,  vaginal  cesarean  section  may  be  done.  Under  the  first  caption 
may  be  placed  eclampsia,  abruptio  placentae,  hyperemesis  gravidarum,  uncompen- 
sated heart  disease,  hmg  disease,  a?dema  pulmonum,  asphyxia  in  utero — in  short, 
all  acute  complications  on  the  part  of  the  mother  or  infant.  Under  the  head  of 
obstructions  cancer,  stenosis,  antefixatio  uteri,  scars  from  old  operations,  may  he 
mentioned  . 

Conditions. — Delivery  from  below  must  be  possible,  that  is,  the  pelvis  must  be 
large  enough  and  presentation  and  position  of  the  cliikl  favorable.  Although  some 
authors  recommend  the  operation  in  placenta  pravia,  I  would  consider  this  a  contra- 
indication, and  Bumm  recently  retracted  his  recommendation.  The  child  must  be 
living,  unless  the  indication  for  haste  on  the  part  of  the  mother  is  imperative. 
The  operation  simply  overcomes  the  resistance  of  the  cervix,  and  it  is  highly  impor- 
tant to  determine  beforehand  if  there  is  an  edema  of  the  connective  tissue  or  exces- 
sive friability  of  the  tissues.  In  30  operations  performed  by  the  author  many 
technical  difficulties  were  encountered.  It  is,  therefore,  not  to  l)e  undertaken' 
except  by  one  skilled  in  pelvic  surgery. 

Operations  Preparing  the  Vagina  and  Pelvic  Floor  for  Delivery. — Episiotomy 
and  the  deep  paravaginal  incisions  have  already  been  described,  and  it  has  also 
been  said  that  the  colpeurynter  may  be  placed  in  the  vagina  to  prepare  it  for  the 
subsequent  delivery.  This  procedure  is  especially  useful  in  breech  and  shoulder 
presentations  in  primiparae.  Some  authors  advise  manual  dilatation  of  the  pelvic 
floor  and  vulva  preparatory  to  forceps  operation  or  other  rapid  operative  delivery, 
and  before  hebosteotomy.  My  o\a\  experience  proves  to  me  that  in  such  cases  we 
do  not  really  stretch  the  muscle  and  leave  its  structure  perfect  afterward,  but  we 
cause  innumerable,  minute  or  larger,  submucous  tears,  and  afterward  the  women 
return,  not  with  torn  pelvic  floors,  but  with  relaxed  pelvic  floors,  the  functional 
result,  however,  being  the  same  or  worse.  I  prefer  a  clean  cut  to  these  unsurgical 
methods,  and  am  convinced  that  the  after-effects  are  much  more  favorable.  Unfor- 
tunately, this  ideal  practice  comes  into  conflict  with  the  desire  to  avoid  the  necessity 
of  "putting  in  stitches,"  which  carries  a  certain  opprobrium  among  the  women. 
I  know  that  many  children  have  been  lost  and  much  invalidism  has  resulted  from 
this  ill-advised  and  objectional^le  sentiment.

CHAPTER  LXX 

PREPARATORY  OPERATIONS  (CONTINUED).— PREPARATION  OF  THE 

BONY  PELVIS 

Enlarging  the  Pelvic  Canal. — Reference  has  already  Ijeen  made  to  the  idea  of 
the  ancients  that  the  bones  of  the  pelvis  soften  and  separate  during  delivery. 
We  make  use  of  the  softening  of  the  joints  and  the  movabilit}'  of  the  bones  on  each 
other  to  produce,  l)y  posture,  actual  enlargement  of  the  diameters  of  the  canal. 
Thus  it  is  certain  tliat  the  Walcher  position  enlarges  the  conjugata  vera,  and  the 
exaggerated  lithotomy,  the  bony  outlet,  particularly  in  its  transverse  dianieter. 
The  idea  of  cutting  the  bony  pelvic  ring  is  not  recent. 

Symphysiotomy  and  Hebosteotomy. — Pinseus,  in  1570,  refers  to  section  of  the  pelvic  bones; 
de  la  Cour\ee,  in  1(355,  delivered  a  child  by  .section  of  the  symphysis  pubis  after  the  mother  aied 
in  labor;  Sigault,  in  1768,  invented  the  operation  of  symphysiotomy,  but  could  not  perform  it 
until  1777.  The  woman,  Alme.  Souchot,  and  her  child,  survived,  but  she  hail  a  permanent  vesico- 
vaginal fistula  and  difficulty  of  locomotion.  Sigault  was  given  a  silver  medal.  In  1775  Aitken 
recommended  section  of  the  bones  on  both  sides  of  the  joint  by  means  of  an  articulated  saw,  but 
never  did  it  on  a  live  woman;  in  1821  Champion  de  Bar  le  Due  pointed  out  the  advantages  of 
cutting  the  l)one  instead  of  the  sj'mphysis,  and  in  1S30  Stoltz,  of  Strassburg,  perfected  the  opera- 
tion of  pubiotomy,  using  a  chain-saw,  very  much  as  it  is  done  today,  but  he  also  operated  onlj-  on 
cadavers.  In  1832  Galbiati  tried  Aitken's  recommendation,  but  the  mother  and  babe  died  from 
the  operation  itself,  and  pubiotomy  all  but  disappeared  until  Gigli,  of  Florence,  in  1894,  drew 
general  attention  to  the  operation  and  published  his  saw, — a  roughened  steel  wire, — which  he 
had  invented  for  the  express  purpose  of  cutting  the  pelvic  girdle.  Bonardi,  in  1897,  performed  the 
first  operation  with  the  saw,  Gigli  operating  in  1902  the  first  time  on  the  living.  Symphysiotomy 
had  a  checkered  career.  In  France  an  acrid  polemic  was  waged  about  it,  and  Baudelocque,  Caseaux, 
DuBois,  and  La  Chapelle  finally  caused  its  abandonment.  In  Germany  and  England  the  oper- 
ation never  obtained  a  foothold,  but  in  Italy,  in  spite  of  its  high  mortality  and  morbidity,  it 
enjoyed  a  sporadic  existence  by  grace  of  Galbiati  and  iSIorisani.  ^^'ith  the  improvement  in  asepsis 
and  instrumentarium  of  the  late  eighties  and  the  proper  selection  of  cases  naturally  the  results 
improved.  In  1891  SpineUi,  a  pupil  of  Morisani,  went  to  Paris,  interested  Pinard  in  the  rc^^ved 
operation,  and  the  latter,  within  a  year,  performed  it  17  times.  In  1892  and  1893  it  was  being 
done  in  all  countries  wdth  the  overenthusiasm  begotten  by  every  new  remedy,  and  for  a  time 
symphysiotomy  threatened  the  firm  po.sition  held  by  cesarean  section.  Toward  the  end  of  the 
last  century,  however,  it  lost  ground  almost  entirely.  Zweifel,  in  Leipsic,  Kerr,  of  Glasgow,  and 
Pinard,  in  Paris,  are  among  its  few  fast  friends  even  today. 

In  1904,  as  the  result  of  the  publications  of  Gigli,  Van  de  Velde,  and  Doderlein,  pubiotomy 
took  the  center  of  the  stage,  and  in  the  subsequent  five  years  hundreds  of  op(>rations  were  per- 
formed the  world  over.  Now  the  enthusiasm  is  waning,  because  it  has  been  found  that  the  op- 
eration has  an  unavoidable  maternal  and  fetal  mortality  and  a  considerable  morbidity.  The 
advantages  of  pubiotomy  over  symphysiotomy  have  already  been  considered  (p.  719),  as  also 
have  the  indications  and  the  time  of  performance  (q.  v.). 

Anatomy. — Figs.  80S  and  809  show  the  anatomy  of  the  field  of  operation.  The  large  venous 
plexuses  are  the  source  of  the  profuse  hemorrhage.  It  is  easily  seen  how  the  triangular  ligament, — 
the  urogenital  septum, — robbed  of  its  anterior  support,  is  always  torn,  exposing  the  urethra,  the 
anguli  vaginae,  and  the  vestibular  structures  to  serious  injury. 

Symphysiotomy. — There  are  several  methods  of  opening  the  pubic  joint,  some 
exposing  the  field,  others  subcutaneous.  Italian  operators  make  a  small  incision 
above  the  pubis,  and,  under  the  guidance  of  the  finger,  pass  a  curved,  ball-pointed 
knife  around  the  joint,  severing  the  cartilage  from  below  upward.  Farabeuf  makes 
a  long  incision  over  the  joint,  cuts  the  ligamentum  suspensorium  clitoridis.  reflects 
the  latter  downward,  passes  a  grooved  director  aromid  the  joint,  and  cuts  down  on 
it  from  before  backward.  In  my  cases  I  made  a  two-inch  incision  over  the  upper 
half  of  the  pubis,  then,  In'  strong  traction,  pulled  the  opening  down  over  the  whole 
joint,  which  was  thus  exjjosed;  then  the  bone  was  divided  from  above  downward 
to  the  ligamentum  arcuatum,  which  was  severed  only  if  necessary.  In  this  way  the 
wound  was  high  up,  away  from  the  flow  of  the  lochia.     After  delivery  the  bones  are

pressed  together,  and  three  catgut  sutures  passed  through  the  deep  structures  over 
them ;  then  the  skin  is  closed  with  interrupted  silkworm-gut  stitches.  Ayres,  of  New 
York,  did  the  operation  entirely  subcutaneously,  with  a  blunt-pointed  bistoury,  and 
Zweifel,  of  Leipsic,  does  it  with  a  Gigli  saw,  in  a  fashion  similar  to  hebosteotomy.

PREPARATORY  OPERATIONS — PREPARATION  OF  THE  BONY  PELVIS 


923 


Hebosteotomy. — Gigli's  original  operation  was  an  open  dissection,  and  the  results 
were  no  better  than  with  symphysiotomy.  Walcher  devised  a  method  of  operating 
entirely  subcutaneously,  which  Bumm  has  simplified.  Doderlein,  before  Walcher, 
had  modified  the  operation  of  Gigli,  and  his  is  the  one  usually  recommended. 

Ddderlein's  Operntion. — Preparations  are  made  for  a  serious  operation,  although  it  is  usually 
not  one.  In  rare  oases  hemorrhage  and  lacerations  occur  which  tax  the  skill  of  tlie  most  expert. 
Fig.  810  shows  the  instruments  needed.  Two  trays  are  to  be  used— one  for  instruments  for  the 
work  on  the  joint  and  the  other  for  the  vaginal  work.  If  it  is  necessary  to  return  to  the  wound 
in  the  joint  after  the  hands  have  had  to  do  with  the  parturient  canal,  the  operator  should  draw  on 
anotlier  pair  of  sterile  gloves. 

The  patient  is  put  in  the  posture  for  delivery  shown  in  Fig.  783,  but  the  legs  are  lield  bv  the

Lower  tier  is  for  the  operative  wound,  and  the  instruments  are  kept  separate  from  the  others,  which  arc  used  for 
the  dehvery. 

Pubic  Tray:  2  scalpels;  4  artery  forceps;  4  8-inch  clamps:  .3  Gigli  saws;  1  pair  handles:  1  needle:  4  small  needles; 
2  tissue  forceps;    2  retractors;    2  scissors:    fiat  spatula;    1  raspatorium;   silkworm-gut,  etc. 

Vaginal  Tray:  Obstetric  forceps:  3  scissors:  6  artery  forceps;  2  ring  forceps;  2  vulsellum  forceps;  3  tissue  forceps;

two  assistants  nearly  horizontally.  A  transverse  or  longitudinal  incision,  one  inch  long,  is  made 
over  the  left  pubic  tubercle,  down  to  the  rectus  fascia  and  through  it,  but  the  latter  cut  is  always 
made  longitudinally,  and  only  large  enough  to  permit  the  finger  to  pass  behind  the  pul>i.s.  This 
finger  gently  separates  the  bladder  and  fat  from  the  bone,  initil  the  ligamentum  arcuatum  is  felt. 
Now  the  needle  (Fig.  811),  armed  with  a  .silk  ligature,  is  guided  by  the  finger  around  the  bone,  the 
point  of  the  needle  adhering  as  closely  to  the  bone  as  possible.  When  the  point  ha.'^  rounded  the 
ligamentum  arcuatum,  it  is  bent  sharply  forward,  while  an  assistant  pulls  the  labiiun  toward  the 
right  .side — this  to  bring  the  opening  in  the  skin  far  from  the  flow  of  the  lochia,  and,  by  the  sliding 
of  the  tis.sues,  to  close  the  passage  of  the  needle.  A  nick  with  the  knife  allows  the  tip  of  the  dull 
needle  to  emerge;  the  thread  is  grasped  and  the  neerile  withdrawn.  The  saw  is  pulleil  through 
by  means  of  this  thread,  and  tlie  saw  handles  attached.  By  to-and-fro  motions  of  the  saw,  the 
action  resembling  cutting  a  bar  of  soap  wath  a  string,  and  making  short  strokes,  the  bone  is  severed. 
In  this  motion  the  saw  may  not  be  sharply  bent.  Mayer  advises  to  place  the  patient  in  the  Wal- 
cher position  while  sawing  the  bone,  and  raise  the  limbs  gradualh-,  to  prevent  too  sudden  separa-

and  Kerr  uses  the  Waleher  for  the  delivery. 

Hemorrhage  is  usually  free  from  both  wounds,  during  and  just  after  the  bone  is  sawn  through. 
Quickly  the  upper  wound  is  packed  with  hot  iodoform  gauze,  a  stitch  of  silkworm-gut  closes  the

lower  puncture,  and  an  assistant  makes  counteriJicssure  from  the  vaginal  sin-face  by  means  of  a 
large  gauze  swab.  In  a  few  minutes  the  hemorrhage  has  usually  ceasefl,  the  gauze  may  be  remo\-ed, 
and  the  pubic  wound  sewed  up  with  three  de(>p  silkworm-gut  sutures.  The  bones  separate  with 
a  dull,  crunchiing  sound,  which  is  very  unpleasant,  at  first  about  2  cm.,  and  during  extraction  up 
to  b  cm.     More  separation  than  this  endangers  the  sacro-iliac  joints.

Some  operators  leave  the  delivery  to  nature  or  wait  for  later  indication,  especially  in  primi- 
parae,  but  by  the  majority  immediate  delivery  is  practised.  In  primipara)  I  prefer  to  leave  the 
delivery  to  nature,  as  does  Stoeckel  also.

It  IS  highly  important  that  the  mechanism  of  labor  be  favorable— a  posterior  occiput  or  a  brow

the  placenta  very  soon  and  pack  the  uterovaginal  tract  witli  gauze  ;us  a  routine.  Now  ail  vaginal 
injuries  are  repaired,  a  clean  pair  of  gloves  put  on,  and  the  piil)ic  wound  inspected  and  treateil, 
if  necessary.     Catheterization  of  the  bladiler  now  determines  if  tiiis  organ  is  injured. 

Subctdancous  Operation. — Bumm  uses  a  sharp,  full-curved  needle  and  passes  it  from  below 
upward  under  the  guidance  of  a  finger  in  the  vagina  (Fig.  S14).  It  is  threaded  with  the  saw,  then 
withdrawn,  and  the  operation  completed  as  al)Ove. 

Complications. — Hemorrhage  is  easiest  to  control  in  the  open  symphysiotomy  when  clamps 
may  be  placed  on  the  crura  clitoridis  and  l)leeding  veins,  but  in  one  case  I  had  to  pack  the  ^•agina 
tightly  and  place  a  sand-bag  on  the  pul)is  to  exert  counterpre.ssure.  In  subcutaneous  operations

rough  handling  of  the  patient  in  transporting  her.  If  they  are  large  and  growing,  tliey  must  be 
incised  and  packed — an  unlovely  operation.  If  suppuration  sets  in,  which  is  not  vnmsual,  early 
drainage  is  indicated. 

Laceralions. — Although  waiting  for  spontaneous  delivery  seems  to  he  the  ideal  treatment 
after  opening  the  pelvis,  the  majority  of  accoucheurs  ar(>  not  in  favor  of  it,  even  aftei-  i)i()i)er 
trial.  It  is  to  be  reserved  for  ])rimipara>,  and  where  no  indication  for  the  immediate  termination 
of  labor  exists.  If  a  vaginal  tear  communicates  with  the  bone,  the  immense  wounfl  Ls  closed  a.s 
far  as  possible,  and  a  gauze  drain  placed  in  the  prevesical  space  and  led  out  through  the  vagina. 
Injuries  to  the  bladder  are  usually  on  its  anterior  wall,  and  cannot  be  repaired  at  this  time.  A 
permanent  catheter  is  placed  in  the  bladder  and  5  grains  of  hexamethylenamin  given  four  times 
daily.  The  catheter  is  to  be  removed  every  six  hours  and  a  new  one  inserted,  and  the  nurse 
must  be  instructed  to  report  inunediately  if  "the  urine  ceases  to  flow — this  to  avoifl  urinary  infil- 
tration. Lacerations  occur  from  too  great  or  too  sudden  separation  of  the  bones,  from  direct 
injury  with  the  needle,  or  the  soft  parts  are  cut  between  the  head  and  the  sharp  edges  of  the  l)ones. 

After-treatment. — After  the  wound  is  dressed  a  broad  adhesive  strip  is  passed  around  the 
pelvis  over  the  trochanters,  and  the  knees  bound  together  with  a  towel.  For  tiie  first  week  great 
care  is  required  in  handling  the  patient,  because  the  bones  are  tender  and  a  hematoma  may  be 
started.  A  bed  arranged  with  a  frame  on  which  the  patient  may  be  raisefl  for  catheterization, 
irrigations,  urination,  etc.,  while  not  absolutely  necessary,  much  facilitates  the  treatment  and

increases  the  puerpera's  comfort.  For  four  days  the  woman  should  lie  on  her  back;  after  this 
she  may  move  about  in  bed,  and  may  get  out  of  it  at  the  end  of  thre(>  weeks,  and  may  walk  as 
soon  as  she  feels  able  to  do  so,  which  is  usually  in  the  fourth  week.  Sj-mphysiotomy  cases  were 
much  more  troublesome  postpartum  than  are  the  hebosteotomies. 

Indications. — Ahnost  the  sole  indication  for  hebosteotomy  is  mechanical 
disproportion  between  the  head  and  the  pelvis.  With  a  normal-sized  fetus,  the 
operation  is  indicated  in  flat  pelves  with  a  conjugata  vera  of  more  than  7  cm.  and 
more  than  l}/2  cm.  in  a  generally  contracted  pelvis.  If  the  child  is  ovcrgrowTi,  of 
course,  the  pelvic  diameters  nmst  be  larger,  but  with  very. large  children  the 
excessive  danger  to  the  soft  parts  must  be  considered  as  contraindicating  this  opera- 
tion. The  indication  for  hebosteotomy  really  depends  on  the  time  the  patient  is  first 
seen.  During  pregnancy,  if  the  pelvic  contraction  is  discovered,  the  induction  of 
premature  labor  may  be  preferretl,  or  the  patient  may  be  allowed  to  go  to  term  and 
a  conservative  cesarean  section  be  performed  at  the  very  beginning  of  labor.  The 
latter  is  my  choice.  Early  in  labor,  and  if  the  woman  is  surely  not  infected,  abdom- 
inal delivery  may  be  done,  or  the  "test  of  labor"  be  awaited.     If  the  labor  test 


928 


OPERATIVE    OBSTETRICS 


shows  that  the  head  will  not  go  through,  hebosteotoniy  is  the  operation  of  choice, 
but  before  this  a  proper  trial  of  the  forceps  should  be  made.  If  the  woman  is  already 
infected,  or  presumably  so;  if  prolonged  attempts  with  forceps  have  been  made  and 
the  maternal  parts  much  bruised;  if  the  child  is  injured  or  not  in  good  condition — 
hebosteotoniy  liecomes  a  dangerous  and  unsatisfactory  operation  and  craniotomy 
must  be  substituted.  With  a  dead  or  dying  child  em])ryotomy  is  the  only  operation. 
It  will  be  seen  that  hebosteotomy  is  useful  only  in  border-line  cases,  where  the  at- 
tendant, believing  the  child  would  be  delivered,  has  waited  until  labor  has  advanced 
so  far  that  cesarean  section  would  be  too  dangerous,  or  has  even  attempted  delivery 
with  the  usual  methods.  The  selection  of  the  operation  now  is  one  of  judgment  of 
the  condition  of  the  mother  and  babe  and  of  the  probable  outlook  for  both.     It  is,

therefore,  largely  subjective.  In  shoulder  and  breech  presentations,  where,  of 
course,  we  cannot  await  the  test  of  labor,  placing  the  indication  becomes  still  more 
su))jective  and  will  be  aided  by  knowledge  of  previous  deliveries,  pelvic  and  fetal 
mensuration,  the  state  of  the  soft  parts,  etc.  I  feel  that  pubiotomy  should  be 
restricted  in  favor  of  abdominal  delivery  in  good  cases,  and  the  older  methods 
should  be  preferred  in  unfavora])le  ones.  In  persistent  occipitoposterior,  and  in 
face  presentation  with  the  chin  immoval)ly  posterior,  an  occasional  indication  for 
section  of  the  pelvis  may  arise.  Lewis  and  Montgomery  did  symphysiotomy  for 
such  conditions,  but  there  are  only  5  others  reported  (Morse). 

Conditions. — (1)  The  pelvis  may  not  be  too  small,  that  is,  less  than  7  cm.  in 
the  flat,  and  73^  cm.  in  generally  contracted,  with  a  child  of  7  pounds.     It  may

not  be  ankylosed,  as  by  tubercular  disease,  advanced  age,  etc.  (2)  The  child 
may  not  be  too  large;  (3)  the  child  must  be  in  good  condition  and  not  deformed,  for 
example,  hydrocephalus,  anencephalus;  (4)  the  maternal  soft  parts  may  not  be 
infantile  nor  rigid,  hence  hebosteotomy  should  seldom  be  attempted  in  primiparae, 
especially  if  very  young  or  old;  (5)  the  mother  must  be  in  good  condition  and  not 
infected,  that  is,  no  fever,  slow  pulse,  clean  conduct  of  labor;  (6)  the  cervix  must  be 
effaced  and  dilated;  (7)  the  woman  must  be  in  a  well-equipped  obstetric  operating- 
room,  with  plenty  of  assistants,  since  the  operation  is  not  one  to  be  done  in  the  home. 
Prognosis. — The  reader  is  referred  to  p.  721.  Recently  reports  by  Williams 
and  Stoeckel  show  series  of  25  and  24  cases  respectively  without  maternal  death, 


Fig.  818. — Leading  Head  into  Pelvis  by  Combined  Pressfre  and  Traction. 

and  with  8  and  4  per  cent,  fetal  deaths,  the  late  results  Ijeing  good.  Locomotion 
was  not  compromised,  though  tenderness  and  pain  were  noted  several  times. 
After  symphysiotomy  there  is  often  a  slight  permanent  enlargement  of  the  pelvis, 
so  that"  subsequent  deliveries  may  be  spontaneous,  but  after  hebosteotomy  this  is 
not  so  marked.  Union  of  the  bones  by  a  strong  fibrous  callus  is  the  rule.  l)ut  in 
many  cases,  especially  after  eight  months,  it  is  bony.  Plastic  operations  on  the 
pubic  bones  have  been  suggested  for  the  permanent  enlargement  of  the  pelvis  by 
Frank,  Fiith,  Crede,  Groves,  and  others,  but  they  are  irrational  and  impractical.

OPERATIVE    OBSTETRICS 


Subsequent  labors  maj'  not  be  treated  by  a  second  symphysiotomy  because  of  the 
immense  scar  which  involves  the  bones,  the  bladder,  the  urethra,  etc.,  but  pubiotomy 
has  on  several  occasions  been  performed  t'\\nce.  I  have  performed  cesarean  section 
in  these  cases  on  principle,  and  in  oni>  case  because  of  the  enormous  varicosities  of 
the  vulva  and  pelvis  which  followed  the  previous  (infected)  pubiotomy.

Improving  the  Position  of  the  Fetus. — Occipitoposterior  positions  occasionally 
require  correction,  and  the  indications  will  be  found  on  p.  580.  The  simple  ma- 
noeuver  of  Hodge,  pressing  up  on  the  sinciput  during  the  pains,  may  increase  flexion 
and  thus  assist  rotation.  By  combined  manipulation  (P'ig.  816)  it  may  be  possible 
to  turn  a  head,  engaged  in  the  pelvis,  far  enough  to  the  front  to  be  able  to  apply 
the  forceps.     Two  or  four  fingers  of  one  hand  obtain  a  purchase  on  the  skull  behind

the  baby's  ear,  and  seek  to  pull  the  occiput  clo^\Tlwarcl  and  forward,  while  the  other 
hand,  outside,  pushes  the  forehead  toward  the  back  part  of  the  pelvis.  When  the 
head  is  in  proper  position,  an  assistant  holds  the  forehead  at  the  point  to  which  the 
operator  pushed  it,  while  the  latter  uses  his  free  hand  to  insert  one  blade  of  the 
forceps.  The  other  hand,  which  has  been  kept  inside  to  prevent  the  occiput  from 
rolling  backward  again,  guides  the  forceps  blade  into  place.  If  the  head  is  not 
engaged,  a  more  complicated  operation  is  required.  Eden  and  Kerr  record  very 
successful  manipulations.  The  following  procedure  has  been  practised  by  the 
author  for  many  years  (Fig.  817,  p.  928).  Under  deep  anesthesia  the  whole 
hand  is  passed  into  the  uterus,  pushing  the  head  up  and  out  of  tiie  pelvis  if  nec- 
essary.    That  hand  is  selected  which  will  have  its  palm  directed  toward  the  face

of  the  infant.  The  posterior  shoulder  of  the  child  is  sought,  and  with  the  tips  of 
the  fingers  is  swung  around  to  the  front,  past  the  promontory  of  the  sacrum.  The 
head  fitting  into  the  palm  of  the  hand  goes  with  the  trunk.  The  hand  outside  aids 
this  motion  by  pulling  the  shoulder  toward  the  front.  When  the  inside  hand  is 
leading  the  head  into  the  pelvis  in  its  new  po.sition,  the  outside  hand  forces  the  head 
down  by  pressure  on  the  occiput,  which  is  now  over  the  pubic  ranms  (Fig.  818,  p. 
929).  It  may  be  advisable  to  draw  the  head  down  deep  into  the  pelvis  with  for- 
ceps, await  four  to  six  labor-pains,  remove  the  forceps,  and  leave  the  case  to  nature, 
or  to  follow  a  later  indication.  The  latter  plan  is  especially  successful  in  primi- 
parse,  because  the  molding  of  the  head  and  the  softening  of  the  tissues  produced  by 
a  few  hours'  labor  and  the  progress  of  the  head  toward  the  outlet  immensely  facili- 
tate the  subsequent  delivery  (see  page  979). 


932 


OPERATIVE    OBSTETRICS 


The  conditions  for  this  operation  arc :  (1 )  The  pelvis  may  not  be  too  contracted 
for  the  subsequent  dehvery;  (2)  the  child  must  be  living;  (3)  the  cervix  must  be 
dilated  to  admit  the  hand;  (4)  the  bag  of  waters  ruptured;  (5)  the  uterus  may  not 
be  in  tetanic  contraction  or  on  the  point  of  rupturing;  (6)  placenta  praevia  and 
prolapse  of  the  cord  may  not  exist.  In  rare  instances  the  manipulation  fails,  or 
must  be  given  up  because  the  force  required  is  too  much  to  be  safely  applied.  Now 
the  forceps  alone  will  be  able  to  effect  delivery,  but  the  operator  must  be  aware 
that  they  are  very  difficult  to  apply  under  such  conditions  and  invarial)ly  cause

superficial  and  deep  injuries  to  the  maternal  parts.  If  the  operation  is  forced,  a 
still-l)irtli  fr('(|uently  results. 

Improving  the  Attitude  of  the  Child.— Faulty  attitudes,  face,  brow,  and  other 
malpresentations,  prolapse  of  extremities  and  of  the  cord,  with  indications  for 
treatment,  have  already  been  considered  (p.  585).  It  remains  to  show  how  face 
and  brow  presentations  may  be  corrected. 

Baudelocque  recommended  to  push  up  the  chin  and  face,  and  then  slide  the 
fingers  over  the  occiput  and  pull  this  down  into  the  pelvis — all  being  done  by  the 
inside  hand.  Schatz  (1872)  sought  to  alter  the  posture  of  the  head  ])y  changing 
the  extension  of  the  trunk  to  flexion.     In  face  presentation  the  usual  C'  shai)e  of 


PREPARATORY    OPERATIONS PREPARATION    OF    THE    BONY    PELVIS

the  child's  spinal  column  is  changed  to  resemble  the  letter  S,  and  Schatz,  operating 
from  the  outside,  by  pulling  the  shoulder  in  one  direction  while  he  pushed  the  breech 
over  in  the  opposite,  in  favorable  cases  could  alter  the  attitude  of  the  trunk  so  that 
the  head  went  over  from  a  condition  of  extension  into  one  of  flexion.  Thorn  ( 1893) 
combined  both  methods,  and  was  more  successful  than  Schatz  in  breaking  the  curves 
of  the  fetal  l^ody  and  producing  the  C  shape  (Fig.  819,  p.  930). 

My  own  method,  which  has  failed  only  once  in  nine  cases  of  face  presentati<to, 


Fig.  822. — ("hanging  Face  to  Occipitai..     Fotrth  Movement. 


and  once  in  three  cases  of  brow  presentation  where  it  was  attempted,  is  similar  to 
Thorn's,  but  more  is  done  by  the  inside  hand. 

Author's  Method. — .\  good  table,  the  obstetric  position,  with  the  nates  well  over  the  edge 
to  allow  the  operator  to  sink  his  elbow,  and  deep  anesthesia  are  indispensable.  The  operation 
consists  of  four  acts — first,  raising  and  releasing  the  head  and  shoulder  from  the  grasp  of  the  uterus, 
so  that  the  baby  floats  free  above  the  inlet;  second,  flexion  of  the  chin  and  forcing  down  the 
occiput;  third,  pushing  in  the  prominent  convexity  of  the  chest  to  a  concavity;  fourth,  leading 
the  now  flexeil  head  into  the  pelvis. 

1.  The  hand,  whose  palm  will  he  against  the  child's  face  (for  example,  in  M.D.P.,  the  left), 


934  OPERATIVE    OBSTETRICS 

is  introduced  into  the  lower  uterine  segment,  and  with  the  fingers  widely  apart  the  head  is  grasped, 
and  with  a  circular  motion  is  loosened  from  its  fixed  position  in  the  inlet.  It  may  l;)c  necessary 
to  raise  the  whole  head  above  the  inlet  into  the  false  pehds.  The  fingers  then  slide  by  the  head 
and  disengage  the  shoulders  from  the  uterine  walls.  The  child  is  thus  rendered  movable,  being 
freed  from  the  grasp  of  the  lower  uterine  segment.  Information  is  also  gained  of  the  condition  of 
the  uterus  as  to  rigidity,  thinning,  etc. 

2.  With  the  same  hantl  the  cliin  and  then  the  face  are  pushed  up,  the  tips  of  the  fingers 
being  applied  in  the  nasal  fossi3e  (Fig.  S20),  while  the  outside  hand  presses  the  occiput  down. 

3.  The  same  internal  hand  now  continues  farther  past  the  face,  either  in  front  of  the  prom- 
ontory or  behind  the  pubis,  until  the  finger-tips  reach  the  chest  and  shoulder  of  the  child. 
Obtaining  purchase  on  the  shoulder,  the  fingers  are  flexed,  which  throws  the  chest  first  into  a 
straight  line  and  then  into  a  concavity,  and  at  the  same  time  the  thinnb  makes  downward  trac- 
tion on  the  occiput,  bringing  the  latter  into  the  palm  of  the  hand  (Fig.  821,  p.  932).  The  out- 
side hand  meanwhile  pushes  the  breech  to  the  side  on  which  the  chin  lay. 

4.  The  inside  hand,  holding  the  head  in  the  now  flexed  attitude,  with  the  fingers  over  the 
face  and  the  thumb  liooked  into  the  suboccipital  region,  gently  leads  the  head  into  the  pelvis, 
the  outside  hand  forcing  the  child  into  extreme  flexion  and  down  toward  the  inlet  (Fig.  822,  p. 
933).  An  assistant  now  places  his  one  hand  on  the  breech,  the  finger-tips  of  the  other  being  over 
the  occiput,  while  the  operator  uses  his  free  hand  to  insert  the  blades  of  the  forceps.  A  few  slight 
tractions  bring  the  head  down  into  the  pelvis,  and  engagement  having  been  obtained,  recurrence  of 
the  face  presentation  is  impossible.  Sometimes  the  first  attempt  at  correction  fails,  or  the  head, 
having  been  flexed,  extends  again  as  soon  as  the  pressure  of  the  hand  is  removed.  To  avoid 
this  the  above  advice  is  given.  In  addition,  the  assistant,  from  the  outside,  sliould  maintain  the 
flexion  of  the  trunk  by  firm  pressure  on  the  breech,  and  the  operator,  by  holding  the  child  in  its 
new  posture  for  five  minutes,  perhaps  aided  by  a  few  pains,  may  make  the  conversion  permanent. 
Though  I  have  never  found  it  necessary,  it  occurred  to  me  to  hold  the  head  in  its  new  attitude 
by  means  of  a  vulsellum  grasping  the  scalp.  The  injury  would  be  no  more  than  is  often  in- 
flicted -with  the  forceps.  It  is  best  not  to  deliver  at  once,  but,  if  possible,  to  leave  the  case  to 
nature,  awaiting  further  indications. 

Indications. — The  sole  indication  for  this  operation  is  mentoposterior  position, 
where,  from  close  observation  of  the  course  of  labor,  the  accoucheur  is  convinced 
that  the  case  is  not  likely  to  terminate  with  anterior  rotation  of  the  chin.  It  is 
not  the  routine  treatment  of  face  presentation. 

Conditions. — (1)  The  cervix  must  l^e  fully  dilated  because  the  hand  must  be 
introduced,  and  it  may  be  necessary  to  deliver  at  once;  (2)  the  bag  of  waters  is  to 
be  ruptured;  (3)  the  child  may  not  be  too  large  nor  the  pelvis  too  small  (very 
important) ;  (4)  the  uterus  must  not  be  too  much  thinned  or  on  the  point  of  ruptur- 
ing; (5)  the  head  may  not  be  deeply  engaged  in  the  pelvis;  (6)  placenta  praevia 
may  not  be  present;    (7)  the  child  must  be  living  and  viable. 

If  an  indication  for  immediate  delivery  on  the  part  of  the  mother  or  child 
exists,  it  may  be  better  to  perform  version  and  extraction,  and  the  same  may  be 
said  of  minor  degrees  of  pelvic  contraction.  In  placenta  pra3via  and  prolapse  of 
the  cord  version  is  the  operation  of  choice. 

Version 

Version,  or  "turning,"  is  an  operation  which  changes  the  polarity  of  the  fetus 
with  reference  to  the  mother,  the  object  being  to  change  an  abnormal,  or  relatively 
abnormal,  relation  into  a  normal,  or  relatively  normal,  one.  Thus  version  may 
change  a  transverse  presentation  to  a  longitudinal  one,  or  a  head  presentation  to 
one  of  breech. 

Version  is  also  very  useful  as  a  preparatory  operation  before  rapid  delivery, 
when  the  latter  is  indicated  by  the  condition  of  the  mother  or  child.  Version  is 
only  a  preparatory  operation.  When  it  is  completed,  the  indication  for  it  is  satis- 
fied. A  new  indication  must  be  present  for  the  extraction,  which  may  not  follow 
without  such  indication. 

Version  bringhig  down  the  head  is  called  "cephalic,"  and  when  the  breech  is 
brought  down,  "podalic."  Version  may  be  done  by  purely  external,  l)y  internal, 
and  by  combined  manipulation — sometimes  called  "  bipolar."  Nowadays  the  purely 
internal  version  is  not  done,  but  always  the  external  hand  is  used  to  aid  the  internal 
one. 

Internal  cephalic  version  was  done  even  before  Hippocrates'  time,  and  was  generally  pre- 
ferred to  podalic  because  of  the  belief  that  the  cliild  could  best  be  born  if  it  came  head  first.     Oelsus,

about  the  time  of  Christ,  Soranus,  one  lum(h-ed  years  after,  and  Aetius  (sixth  century  a.d.) 
performed  podahc  version,  but  this  knowledge  was  lost  in  the  dark  ages,  until  Ambroise  Pare, 
in  1550,  described  and  very  successfully  performed  the  operation.  Wiegand,  in  1807,  introduced 
external  version,  but  the  procedure  had  been  previously  used  in  Japan  and  Alexico  as  an  empiric 
measure  during  pregnancy  to  favor  labor,  and  by  Pechey  in  England  as  early  as  1698.  Hohl, 
in  1845,  Wright,  of  Cincinnati,  in  1854,  and  Braxton  Ilicks,  in  1860,  perfected  the  combined 
methods  of  version. 

Version  in  Transverse  Presentation. — If  recognized  during  pregnancy,  the 
transverse  position  of  tiie  child  may  be  clianged  by  the  woman  assuming,  when  in 
bed,  a  posture  which  favors  descent  of  the  head — that  is,  she  should  lie  on  that  side 
on  which  the  head  lies.  The  breech  then  falls  over  to  the  side,  the  head  sliding  over 
the  inlet.  In  spite  of  a  snugly  fitting  binder  the  child  may  not  remain  in  the  new 
relation.  Even  during  the  first  stage  of  labor  postural  treatment  is  to  be  tried, 
but  here  external  cephalic  version  is  the  operation  of  choice  if  operation  is  needed. 


Fig.  823. — Wiegand's  External  Version. 


Unquestionably,  cephalic  presentation  is  the  most  favorable  for  mother  and  child, 
and  we  should  try  to  bring  the  head  into  the  inlet  by  external  cephalic  version, 
governed,  however,  by  the  following  conditions:  (1)  There  should  be  no  contrac- 
tion of  the  pelvis  unless  pubiotomy  is  in  anticipation,  and  the  child  msiy  not  be  too 
large;  (2)  there  should  be  no  immediate  or  prospective  indication  for  the  rapid 
termination  of  labor,  because  if,  under  such  circmnstances,  the  head  did  not  at 
once  engage,  another  operation — podalic  version — would  of  necessity  have  to 
follow;  (3)  the  fetus  must  be  very  movable,  which  means  that  the  bag  of  waters 
must  be  intact  and  the  pains  absent  or  weak.  Placenta  prsevia,  prolapse  of  the 
cord,  and  monstrosities  are  contraindications,  and  a  fat  or  tender  abdomen  may 
make  the  manceuver  impossible. 

Cephalic  version  has  very  limited  application,  but  I  am  convinced  it  is  used 
less  often  than  it  should  be.  ]Most  accoucheurs  prefer  to  wait  for  complete  dilata- 
tion and  then  do  podalic  version  and  extraction. 

Wiegand's  Method. — Anesthesia  is  rarely  needed,  but  the  patient  must  learn  to  relax  the 
belly-wall.     By  using  a  partial  Trendelenburg  posture  the  child  falls  away  from  the  inlet  and 


936  OPERATIVE    OBSTETRICS 

becomes  more  movable.  One  liand  is  placet!  over  the  breech,  the  other  over  the  head,  and  by 
alternate  stroking  and  pushing  movements  the  head  is  lirought  over  the  inlet.  Operating  between 
pains  one  holds,  during  the  time  the  uterus  is  contracting,  what  has  been  gained.  Time  is  no 
object,  and  force  may  not  be  used.  Now  tlie  foot  of  the  table  is  lowered,  and  the  head  forced 
down  into  the  inlet,  wliere  it  is  held  for  five  minutes  or  until  the  pains  fix  it  there.  If  the  cerNnx 
is  completely  dilated,  and  if  the  cord  or  the  extremities  have  not  prolapsed,  the  bag  of  waters 
may  be  ruptured,  still  holding  the  head  firmly  in  the  inlet.  If  the  cervix  is  not  dilated,  or  if  the 
cori  Ues  over  the  os,  the  membranes  may  not  be  ruptured.  Combined  internal  and  external 
version  to  bring  the  head  over  the  inlet  is  almost  never  practised  nowadays,  though  it  should  be. 

Podalic  Version. — "When  version  or  turning  is  mentioned,  it  is  usually  the 
podalic  one  that  is  meant,  and  it  is  preferred,  because — (1)  As  a  rule,  cephalic 
version  is  too  difficult  or  impossible ;  (2)  there  is  an  immediate  or  prospective  indi- 
cation, either  on  the  part  of  the  mother  or  the  child,  for  rapid  delivery;  and  (3) 
there  is  often  slight  pelvic  contraction.  Lately  the  latter  indication  is  being  much 
restricted  in  favor  of  pubiotomy  and  cesarean  section.  If  a  case  of  transverse 
presentation  occurs  in  a  contracted  pelvis,  the  pelvis  and  not  the  presentation  of 
the  child  decides  the  course  to  pursue. 

Very  few  operators  try  to  turn  by  the  breech  with  external  manipulations 
alone,  but  I  have  several  times  succeeded  in  doing  so,  and  it  is  almost  always  pos- 
sible if  the  case  is  simply  one  of  deflected  breech  presentation.  There  are  two 
methods  of  combined  or  bipolar  version  which  are  employed,  according  as  the 
cervix  is  open  enough  to  admit  the  hand  or  only  enough  for  one  or  two  fingers. 
The  name  of  Braxton  Hicks  is  most  often  associated  with  the  last  method,  because 
he  did  so  much  to  popularize  it.  The  other  method  might,  with  propriety,  be 
called  "bimanual"  version. 

^^Tlich  of  these  methods  is  used  depends  on  the  condition  of  the  cervix  and  the 
mobility  of  the  fetus.  If  the  cervix  is  completely  dilated,  bimanual  version,  rup- 
turing the  bag  of  waters,  is  performed.  If  the  cervix  is  not  dilated  and  the  bag  of 
waters  is  intact,  it  is  best  to  wait.  One  may  not  go  away,  but  should  stay  by  the 
patient  so  as  to  interfere  when  needed.  If  the  cervix  will  admit  only  two  fingers, 
but  the  bag  of  waters  is  ruptured,  Braxton  Hicks'  version  is  indicated.  It  is  dan- 
gerous to  wait  after  the  bag  of  waters  is  ruptured  for  the  cervix  to  dilate  to  a  size 
sufficient  to  allow  the  hand  to  pass  through.  Braxton  Hicks'  version  should  be  con- 
sidered, and  if  not  thought  feasible,  a  metreurJ^lte^  should  be  put  into  the  lower  uter- 
ine segment  to  preserve  the  balance  of  the  liquor  amnii,  to  keep  the  shoulder  away 
from  the  inlet,  and  to  prevent  prolapse  of  the  cord  and  extremities.  When  the 
cervix  is  well  dilated,  the  time  is  ripe  for  the  bimanual  version.  Should  an  indica- 
tion on  the  part  of  the  child  for  rapid  delivery  arise  before  full  dilatation  is  accom- 
plished, the  various  methods  of  opening  the  cervix  must  be  taken  up  as  additional 
preparatory  measures.  Version,  followed  by  extraction  through  an  only  partly 
opened  cervix,  is  a  dangerous  and  often  fruitless  operation. 

Bimanual  Version  in  Transverse  Presentation. — Few  operations  are  so  satis- 
factory as  version,  but  none  is  more  dangerous  if  performed  without  due  consider- 
ation of  the  conditions. 

Conditions. — (1)  The  cervix  must  be  dilated  enough  to  allow  the  hand  to  pass, 
and  if  the  version  is  done  in  the  presence  of  an  indication  for  extraction  also, 
it  must  be  fully  dilated;  (2)  the  pelvis  may  not  be  too  much  contracted — this 
in  view  of  the  extraction  to  follow;  (3)  the  uterus  may  not  be  in  tetanus  or 
retracted  over  the  fetus — that  is,  the  case  may  not  be  one  of  neglected  transverse 
presentation  with  the  uterus  on  the  point  of  rupture ;  (4)  the  child  must  be  mobile, 
that  is,  not  engaged,  or  in  the  process  of  spontaneous  evolution;  (5)  unless  the 
version  promises  to  be  exceptionally  easy,  the  child  must  be  living. 

The  third  and  fourth  conditions  require  most  careful  thought;  indeed,  it  is 
at  this  point  that  the  art  of  the  accoucheur  comes  into  play.  To  know  when  it  is 
safe  to  turn  and  when  the  risks  of  rupture  of  the  uterus  are  too  great  requires  much 
experience  and  delicate  judgment.     Only  too  easy  is  it  to  rupture  a  thinned  lower

uterine  segment,  and  the  inexperienced  accoucheur  would  do  better  to  err  on  the 
side  of  safety  to  the  mother.  It  is  impossible  to  lay  dowTi  a  set  rule  as  to  how  long 
after  the  rupture  of  the  meml)ranes  a  version  is  still  permissible.  All  depends  on 
the  degree  of  retraction  and  contraction  of  the  uterus.  The  longer  the  time,  the 
more  difficult  and  dangerous  the  operation.  I  have  done  a  turning  three  days  after 
the  membranes  ruptured,  and  again  have  found  it  impossible  two  hours  afterward. 
The  preparations  are  the  same  as  for  all  obstetric  operations.  The  instruments 
required  are  those  for  the  operation  chosen  for  the  delivery  of  the  child — as  forceps

In  passing  the  hand  through  the  vulva  the  labia  are  to  be  widely  parted;  the  direction  is  at  first  downward 
toward  the  sacral  hollow,  then  upward  in  the  axis  of  the  inlet,  .sinking  the  elbow  downward,  and  the  motion  should  be 
spiral,  from  left  to  right.  The  hand  is  well  lubricated  with  lysol  solution.  While  the  outside  hand  steadies  the 
uterus,  the  inner  one  gently  pushes  up  the  shoulder,  and,  by  stroking  the  uterine  wall,  frees  it  from  its  grasp  on  the 
child,  at  the  same  time  noting  its  thinness,  or  perhaps  any  present  break  in  its  surface. 


or  breech  extraction.  For  the  version,  several  slings  are  to  be  provided,  smooth 
tape  a  j-ard  or  more  long  and  Yi  inch  wide,  and  some  sort  of  sling-carrier.  Profound 
narcosis  is  needed  for  the  actual  turning,  but  later  a  lighter  sleep  is  preferable. 
]\Iost  often  the  dorsal  posture  is  sufficient,  but  in  back-posterior  positions  and 
pendulous  belly  the  lateral  (the  one  on  which  the  child's  feet  are)  may  be  required. 
A  modified  Trendelenburg  may  be  used  instead.  One  is  here  governed  l)y  surround- 
ing conditions. 

AATiich  hand  shall  be  introduced?     That  hand  whose  palm  will  lie  against  the 
breech  when  in  the  uterus — when  the  breech  is  to  the  left,  the  right,  when  to  the

OPERATIVE    OBSTETRICS 


right,  the  left,  hand.  The  bag  of  waters  is  usually  ruptured;  it  not,  the  membranes 
are  to  be  opened  just  as  the  hand  passes  the  cervix;  the  forearm  then  will  fill  the 
vulva  and  prevent  the  escape  of  all  the  liquor  amnii. 

"Which  foot  is  to  be  seized?  All  authorities  recommend  to  In-ingckn^ai  the  lower 
foot  in  back-anterior  presentations,  and  Simpson  and  Hohl  urged  to  get  the  upper 
one  in  back-posteriors.  They  claimed  that  then  the  back  of  the  baby  would  rotate 
so  as  to  come  anteriorly,  which  would  be  more  favorable  in  the  subsequent  extrac- 
tion.    This  is  my  practice,  but  in  cases  where  it  is  at  all  difficult  to  reach  the  feet, 


Fig.  825. — Version.  Second  Motion.  Hand  Seizing  Foot. 
Passing  the  hand  directly  along  the  belly  or  .side  of  the  fetus,  taking  care  to  avoid  the  cord,  the  fingers  touch, 
successively,  thigh,  knee,  and  ankle.  Aided  by  the  outside  hand,  the  upper  foot  is  pressed  into  the  grasp  of  the 
thumb  and  the  two  first  fingers,  which  seize  it,  without  making  the  hand  into  a  knobby  fist.  This  is  avoided  because 
the  uterus  might  tear  over  the  sharp  knuckles,  and,  further,  the  fist  and  the  body  of  the  child  make  too  wide  a  mass 
for  the  safety  of  the  lower  uterine  segment. 


I  usually  take  that  one  which  I  first  identify  as  such.  The  version  is  to  be  made 
on  one  foot,  if  possible.  This  leaves  the  other  leg  and  thigh  to  add  volume  to  the 
breech  end  of  the  fetal  pole,  and  thus  produce  greater  dilatation  of  the  cervix, 
which  renders  the  passage  of  the  head  easier. 

What  to  do  with  a  prolapsed  arm?  It  is  best  to  put  a  sling  on  it,  then  lay  the 
end  of  the  tape  in  one  groin.  Later,  during  the  extraction,  an  assistant  keeps  up 
light  traction  on  it  to  hold  the  arm  alongside  the  trunk.  This  is  good  practice,  as 
it  dilates  the  cervix  more  and  renders  nmch  easier  the  delivery  of  the  arms  and

shoulder-girdle.  I  often  bring  down  the  arm  purposelj'  to  put  a  sling  on  it.  Should 
the  arm  prolapse  before  the  cervix  is  prepared  for  delivery,  it  may  be  replaced  in 
the  uterus  and  a  bag  inserted  to  procure  complete  dilatation. 

After  the  version  is  complete,  the  operator  has  fulfilled  the  indication  for  which 
the  operation  was  done.  He  assures  himself  that  the  child  is  in  good  condition 
(fetal  heart-tones),  and  that  the  placenta  has  not  been  abrupted  by  the  manipula- 


FiG.  826. — Version.     Thikd  Motion. 

Gently  the  foot  is  drawn  into  the  pelvis,  sliding  it  down  the  wall  of  the  uterus  behind  the  pubis.  In  back-anterior 
presentations  the  foot  is  led  down  posteriorly  near  the  sacro-iliac  joint,  where  there  is  more  room.  The  outside  hand 
aids  the  turning  by  pressing  the  head  toward  the  midline  and  upward.  During  the  uterine  contraction  no  motion  may 
he  made:  the  hands  are  to  lie  absolutely  quiet.  Between  pains  the  operation  is  renewed.  At  all  stages  the  back  of  the 
internal  hand  should  feel  the  wall  of  the  uterus  and  discover  a  separation  of  its  fibers,  or  a  beginning  abruptio  placenta. 
When  the  knee  has  passed  the  vulva,  the  version  is  complete;    the  head  will  now  be  found  in  the  fundus 

If  there  is  difficulty  iu  performing  this  act — the  actual  turning — see  that  the  narcosis  is  deep  enough  to  paralyze 
the  uterus;  pass  the  hand  around  the  child  to  find  if  the  shoulder  is  caught  on  the  pelvic  brim;  then,  if  necessarj-, 
bring  down  both  legs. 

If,  during  the  operation,  the  hand  instead  of  the  foot  be  brought  down,  no  harm  is  done — a  sling  is  put  on  it.  It 
is  rare  not  to  be  able  to  reach  the  feet — then  the  knee  may  be  pulled  down.  If  the  cord  prolapses,  the  version  must  be 
hurried.  Such  an  accident  is  to  be  avoided,  if  possible,  and  shows  the  wisdom  of  procuring  complete  dilatation  before 
turning.  Should,  during  the  operation,  a  beginning  rupture  of  the  uterus  be  discovered,  further  attempts  to  turn  are 
too  dangerous — cesarean  section  is  considered,  and,  if  this  is  contraindicated,  embryotomy  is  required. 


tions  (external  hemorrhage  and  bad  heart-tones) ;  further,  he  has  nothing  to  do. 
Often  during  the  version  the  child  suffers  and  the  heart-beat  may  be  very  slow 
after  the  turning  is  completed.  It  is  wise  to  watch  a  while  before  extracting,  be- 
cause usually  the  child  recovers  quickly.  A  hasty  delivery  would  hurt  the  child 
more — its  chances  would  be  improved  by  a  short  respite.  It  is  best  to  leave  the 
delivery  to  nature,  but  the  accoucheur  may  not  leave  the  woman.  She  is  to  remain 
on  the  table,  or  temporarily  put  in  a  bed  near  by.     If  an  indication  on  the  part  of 


940 


OPERATIVE    OBSTETRICS 


the  mother  or  child  arises,  extraction  may  be  performed  in  the  classic  manner. 
Expediency — for  example,  the  accoucheur  not  having  time  to  await  the  natural 
expulsion  of  the  child — is  a  i)oor  indication  for  extraction. 

Podalic  Version  in  Head  Presentation. — Indications. — (1)  Abnormal  attitude 
of  the  child — face  and  brow,  anterior  and  posterior  parietal  bone  presentation.  In 
face  and  brow  cases  version  is  preferred  by  many  to  attempts  to  convert  the  pres- 
entation to  'dn  occipital.  If  the  face  or  brow  case  is  complicated  by  a  prolapsed 
cord  or  placenta  praevia,  etc.,  version  is  the  operation  of  choice,  when  vaginal  deliv- 
ery is  to  be  attempted.  Anterior  and  posterior  parietal  bone  presentation  usually 
are  caused  by  contracted  pelvis,  and  this,  not  the  abnormal  presentation,  should 
give  the  indication ;  (2)  prolapse  of  the  cord  and  of  extremities ;  (3)  placenta  previa; 
(4)  any  complication  on  the  part  of  the  mother  or  child  which  demands  the  rapid 


Fig.  827. — Version  in  Sc.L.P.,  with  Patient  on  Side. 
For  back-posterior  positions,  the  lateral  posture  or  a  modified  Trendelenburg  is  best.  The  hand  is  to  be  passed 
behind  the  piiliis  anteriorly,  but  enters  the  vagina  and  rounds  the  inlet,  as  in  Sc.L..\.,  the  elbow  being  well  depressed. 
Preferably,  the  upper  foot  is  grasped,  but  not  if  there  is  too  much  trouble  to  get  it.  This  turns  the  child's  back  to 
the  front,  but  if  the  lower  foot  needs  be  taken,  it  is  easy,  in  the  following  extraction,  to  favor  rotation  of  the  trunk, 
so  as  to  bring  the  back  anteriorly. 


termination  of  labor,  when  the  conditions  for  forceps  are  not  fulfilled,  for  exanii)le, 
non-engagement  of  the  head;    (5)  contracted  pelvis  of  mild  degree. 

The  last  indication  is  the  most  discussed  one,  and  is  not  yet  settled.  The 
operation  of  version  for  contracted  pelvis  is  called  "prophylactic  version" 
(Fritsch),  and  comes  into  competition  with  prolonged  expectancy,  and  later,  if  the 
head  does  not  engage,  with  the  high  forceps.  Pare,  in  1550,  recommended  this 
operation,  and  it  has  been  done  ever  since.  The  question  is,  does  the  head  pass 
through  a  slightly  contracted  pelvis  easier  coming  last  than  going  first?  Ex- 
perience and  experiment  on  the  cadaver  prove  that  it  does,  but  it  has  to  come 
through  quicker,  and  as  a  result  many  babies  die.  Wolff  and  Leopold  showed 
that  the  results  were  about  the  same.  The  amount  of  damage  done  the  children 
and  the  mother  is  about  equal ;  it  remains,  therefore,  a  matter  of  personal  choice. 
British  accoucheurs,  prominently  Kerr,  have  given  up  prophylactic  version  in  favor 
of  prolonged  expectancy  and  forceps,  which  is  the  position  I  take  in  the  matter. 


PREPARATORY  OPERATIONS — PREPARATION  OF  THE  BONY  PELVIS

Conditions.— (1)  The  cervix  must  be  dilated  enough  for  the  method  of  version 
chosen,  and  if  the  operation  is  done  to  save  the  child,  it  must  always  be  fully  effaced 
and  dilated;  (2)  the  head  must  be  movable,  not  engaged,  but  under  profound 
anesthesia  an  apparently  fixed  head  may  often  be  easily  pushed  up  into  the  false 
pelvis;  (3)  the  pelvis  must  be  roomy  enough  for  the  extraction  to  follow;  (4)  the 
soft  parts  may  not  be  too  rigid — in  primiparaj  version  is  to  be  restricted  to  the 
minimum  possible;  with  some  accoucheurs  primiparity  contraindicates  version; 
(5)  the  uterus  may  not  be  in  tetanus  or  on  the  point  of  rupturing. 

Methods. — Of  these  there  are  three:  Wiegand's  external  version,  the  bimanual, 
or  combined  internal  and  external,  using  the  whole  hand  in  the  uterus,  and  Braxton

Inserting  the  hand  past  the  head  into  the  lower  portion  of  the  uterus,  the  operator  quickly  perceives  if  there  i.s  any 
dangerous  thinning  of  the  wall  or  if  the  contraction  ring  is  tetanically  contracted  about  the  child'.s  neck.     Aided  by 
the  outside  hand  forcibly  pressing  the  breech  down,  the  anterior  foot  is  seized  by  the  inner  hand  without  flexion  of 
the  fingers.     Deep   narcosis  is  required. 


Hicks',  inserting  onlj-  one  or  two  fingers  through  the  cervix.  What  was  said  about 
version  in  shoulder  presentation  regarding  preparations,  posture,  hand  to  choose, 
bag  of  waters,  prolapse  of  the  cord,  and  rupture  of  the  uterus  applies  here.  The 
anterior  foot  is  the  one  to  seize,  because  it  brings  the  back  to  the  pubis.  In  face 
cases  it  is  necessary  to  pass  the  hand  far  up  into  the  fundus,  but  it  is  also  \nse  first 
to  bend  in  the  child's  chest  curve  antl  force  the  breech  down  onto  tiie  internal  hand, 
making  the  child  more  of  a  ball  than  of  long  cylinder  shape.  The  "double  manual, "' 
a  procedure  invented  by  Justine  Sigmundine,  consisting  of  pulling  on  a  sling  at- 
tached to  the  leg  while  pushing  the  head  up  with  the  hand  from  the  inside,  and  the 
manoeuver  illustrated  in  Fig.  831,  are  often  needed. 


942 


OPERATIVE    OBSTETRICS 


Braxton  Hicks'  version  has  a  limited  application  because,  in  cases  where 
version  is  indicated,  it  is  almost  always  desirable  to  be  in  a  position  to  extract  the 
child  when  the  turning  is  complete,  and,  too,  as  we  have  seen,  often  an  accident 
happens  during  the  operation  which  demands  immediate  extraction.  Therefore 
the  author  recommends,  in  all  cases  where  possible,  to  procure  complete  chlatation 
of  the  cervix  before  attempting  to  turn  the  child. 


Fig.  829. — Podalic  Version  in  Occipit.^l  Presentation. 
While  drawing  the  foot  down  in  the  axis  of  the  inlet,  the  outside  hand 
pushes  the  head  of  the  child  directly  inward  toward  its  belly,  thus  making  a 
ball  of  its  body,  which  thus  rotates  better  in  the  uterus.     When  the  knee 
is  at  the  vulva,  the  pressure  on  the  head  by  the  outside  hand  is  upward. 

The  main  indication  for  Braxton  Hicks'  version  ^s  placenta  pra>via.  It  is 
sometimes  done  for  prolapse  of  the  cord,  occasionally  in  shoulder  presentations,  and 
very  exceptionally  to  turn  the  head  down  in  breech  presentation.  The  conditions 
are  the  same  as  for  the  operation  last  descril)ed,  but  the  mobility  of  the  fetus  must 
be  absolutely  free. 

Cephalic  Version  in  Breech  Presentation.— ^yhilc  this  is  the  very  oldest  kmd

During  pregnancy,  if  breech  presentation  is  discovered,  an  attempt  to  change  it  by 
external  manipulation  is  justifiable,  though  it  does  not  always  succeed.  The  knee- 
chest  posture  assumed  three  or  four  times  daily  may  facilitate  the  rotation  of  the 
fetus.     During  labor  in  a  primipara  with  breech  presentation,  with  or  without  a

these  cases,  also,  it  is  wise  to  procure  full  enlargement  of  the  cervical  canal  before 
operating,  so  as  to  l)e  able  to  care  for  all  possible  accidents — for  example,  prolapse 
of  the  cord  or  abruptio  placentae — by  immediate  delivery. 

The  prognosis  of  version  may  never  be  lightly  estimated.  It  depends  largely 
on  the  skill  of  the  operator.  The  operation  may  be  directly  fatal  to  the  mother 
from  rupture  of  the  uterus,  of  the  cervix,  or  from  abruptio  placentse.  The  danger 
of  rupture  of  the  uterus  during  version  cannot  be  too  strongly  emphasized.  For 
the  child,  the  conditions  requiring  the  interference  usually  determine  the  outlook. 
The  turning  itself,  unless  unduly  prolonged  by  complications,  by  abruptio  placentae, 
or  by  prolapse  of  the  cord,  affects  the  infant  but  little.

CHAPTER  LXXI 

OPERATIONS  OF  DELIVERY 

Under  this  heading  will  be  considered  those  operations  which  remove  the 
child  from  the  parturient  canal — breech  delivery,  forceps,  craniotomy,  and  cesarean 
section.  The  technical  term  "extraction"  would  apply  to  all  such  manoeuvers, 
but  usage  has  limited  it  to  the  removal  of  the  unmutilated  child  through  the  natural 
passages. 

EXTRACTION 

General  Indications. — Why  should  we  desire  to  deliver  the  woman?  Why 
must  we  extract  the  child?  Here  is  the  broad  indication  in  a  few  words.  We 
deliver  the  child  because  the  mother  is  unable  to  do  so.  The  indication  for  extrac- 
tion, therefore,  is  insufficiency  of  the  powers  of  labor,  and,  as  Schauta  did,  this 
general  indication  may  be  subdivided  into,  first,  absolute  weakness  of  the  powers; 
second,  relative  insufficiency;  third,  insufficiency  of  the  powers  in  relation  to  the 
necessary  rapid  termination  of  labor.  Under  the  first  head,  actual  weakness  of 
the  forces  of  labor,  may  be  mentioned  weak  pains  from  maldevelopment  of  the 
uterus,  fibroids,  overdistention,  poor  imiervation,  tetanus  uteri,  hour-glass  con- 
traction, infantilism,  rupture  of  the  uterus,  generally  poor  muscular  development, 
diastasis  recti,  inflammatory  conditions  in  the  abdominal  cavity  which  weaken 
the  abdominal  muscles,  etc. 

Relative  insufficiency  of  the  powers  may  be  due  to  increase  of  the  resistances 
offered — (a)  on  the  part  of  the  mother,  such  as  rigidity  of  the  cervix,  vagina, 
perineum;  contracted  pelvis;  tumors  of  the  passage;  and  (6)  on  the  part  of  the  child, 
such  as  overgro'v\i:h,  hydrocephalus,  malpresentations,  malpositions,  etc.  The 
pains  may  be  strong  or  even  stronger  than  usual,  yet  unable  to  complete  delivery. 

Insufficiency  of  the  powers  in  relation  to  the  desired  rapidity  of  the  delivery  is 
a  very  common  indication  for  extraction.  The  powers  may  be  sufficient  and  effi- 
cient, the  resistances  may  be  normal  or  even  less  than  normal,  and  the  woman  could 
complete  the  labor  unaided,  but  a  complication  has  arisen  demanding  immediate 
delivery.  A  few  may  be  cited— on  the  part  of  the  mother,  eclampsia,  acute  and 
chronic  pulmonary  and  heart  diseases,  hernia,  appendicitis,  hemorrhage  from  the 
genitals  or  from  the  lungs,  etc.,  and,  on  the  part  of  the  child,  asphyxia  threatening 
from  any  cause,  or  severe  compression  of  the  brain,  etc. 

General  Conditions. — (1)  The  pelvis  may  not  be  too  severely  contracted. 
A  flat  pelvis  with  a  ccjnjugata  vera  of  less  than  8  cm.  will  very  rarely  permit  a  nor- 
mal-sized child  to  pass,  and  if  the  pelvis  is  a  justominor  one,  a  conjugata  vera  of 
nearly  9  cm.  is  necessary.  If  the  child  is  estimated  to  weigh  over  8  pomids,  the 
conjugata  vera  must  be  over  9  cm.  In  short,  an  absolute  prerequisite  for  extraction 
is  that  there  be  no  insuperable  disproportion  between  the  babe  and  the  pelvis. 
If  pubiotomy  or  emljryotomy  is  in  reserve,  the  degree  of  contraction  may  not  go 
below  l}/i  cm.  and  63^  cm.  respectively. 

(2)  The  cervix  must  be  effaced  and  the  os  dilated.  This  condition  is  impor- 
tant in  relation  to  the  ease  of  the  extraction,  the  integrity  of  the  maternal  tissues, 
and  the  life  and  safety  of  the  child.  If  it  is  necessary,  in  the  interests  of  the  infant 
or  the  mother,  to  deliver  before  this  prerequisite  is  fulfilled,  the  cervix  must  be 
opened  by  one  of  the  preparatory  operations — metreurysis,  incisions,  etc.     The 

946

947 


evils  of  extraction  l^efore  dilatation  is  complete  have  been  referred  to,  and  will  bear 
reiteration. 

(3)  Before  delivery  the  bag  of  waters  must  be  ruptured. 

(4)  With  few  exceptions  one  must  insist  that  the  child  be  living. 

If  the  child  is  dead,  embryotomy  is,  as  a  rule,  a  preferable  operation.     If  in 
doubt,  the  child  gets  the  benefit,  within  a  reasonable  limit. 

(5)  In  cephalic  presentations  the  head  must  be  engaged  in  the  pelvis,  or  so

An  assistant  makes  continuous  even  pressure  over  the  whole  uterus  with  both  hands.     The  accoucheur  takes

spines,  the  others  evenly  distributed  over  the  pelvis  and  thighs.     Gentle,  even  traction  is  made  downward  in  the  di-

the  treatment  of  breech  presentation. 

Manual  Aid. — Even  though  the  majority  of  breech  labors  ends  A\dthout  the 
necessity  of  aid  by  the  accoucheur,  it  is  wase  to  have  the  woman  on  a  proper  table 
and  to  have  all  the  instruments  for  forceps  delivery  and  for  the  repair  of  lacerations 
ready,  with  the  room  cleared  for  operation.  When  the  breech  has  been  delivered, 
the  woman  is  urged  to  bear  down,  faihng  which  an  assistant  exerts  strong  pressure 
on  the  child  from  the  abdomen,  and  if  this  does  not  make  rapid  progress,  the  indi- 


948 


OPERATIVE    OBSTETRICS 


cation  for  ''manual  aid"  is  present.  In  multipanr  manual  aid  is  seldom  required. 
An  anesthetic  is  used  only  if  the  woman  is  unruly  or  if  the  soft  parts  are  very  rigid. 
In  primipane  I  make  a  deep  unilat(Tal  einsiotomy — on  the  side  on  which  tlie  occiput 
will  come  dc^ii — as  a  routine  measure.  It  facilitates  all  the  manipulations  of  the 
delivery,  preserves  the  child  from  injury  due  to  the  application  of  force,  saves  time, 
which  lessens  the  danger  of  asphyxia,  and  safeguards  the  sphincter  ani  from  lacer- 
ation. If  the  child  is  astride  the  cord,  the  latter  is  gently  loosened  and  stripped 
over  one  thigh,  failing  which  it  is  cut  between  two  ligatures  and  the  delivery  rapidly 
ended.  The  bladder  is  to  be  empty.  Feces  issuing  from  the  anus  must  be  carefully 
removed,  and  this  part  watched  with  great  solicitation,  because  in  the  hurry  of  the

Thn  posterior  shouldor  and  arm  are  to  be  disengaged  first,  using  the  hand,  whose  palm  will  apply  flat  to  the  child's 
back.  The  other  hand  seizes  the  two  feet  of  the  infant  and  swings  the  body  through  an  arc  toward  the  mother's  groin, 
which  motion  draws  the  shoulder  down  into  the  hollow  of  the  sacrum,  bends  the  child  around  the  ramus  pubis,  and  gives 
more  room  for  the  insertion  of  the  hand.  Leaving  the  thumb  outside,  two  fingers  are  passed  over  the  back,  over  the 
shoulder,  down  the  arm,  to  the  elbow,  and  wipe  the  arm  over  the  face  and  chest,  down  and  out  of  the  vulva. 


successive  manceuvers  it  is  only  too  easy  to  soil  the  operating  hand  and  carry 
infection  into  the  uterus.     (See  p.  906.) 

Complete  Extraction. — When  in  breech  cases  an  indication  arises  for  delivery, 
preparations  are  identical  with  those  for  version.  The  operation  itself  is  divided 
into  four  acts:  First,  bringing  out  the  breech  and  legs;  second,  delivery  to  the 
shoulders;  third,  disengaging  shoulder-girdle;  and  fourth,  the  birth  of  the  head. 
Complete  extraction  is  manual  aid  preceded  by  one  act,  7.  e.,  bringing  do\ATi  the 
foot  or  feet. 

First  Act. — How^  to  deliver  the  })reech  will  depend  on  its  station  or  location  and 
upon  the  attitude  of  the  child.  If  the  breech  is  deeply  engaged  in  the  pelvis,  a 
little  traction  with  the  finger  in  one  groin  may  suffice;  if  one  or  both  feet  are  down, 
traction  is  made  on  the  extremity.  The  following  methods  have  been  employed  to 
deliver  the  breech:  (a)  Bringing  down  one  leg;  (h)  the  finger  in  the  groin;  (c)  the 
use  of  a  fillet  or  sling  placed  over  the  groin;    ((/)  a  l)lunt  hook,  or  two  hooks,  one  in

949 


each  groin,  or  specially  constructed  forceps,  shaped  like  hooks;    (e)  use  of  the 
obstetric  forceps  on  the  breech. 

Of  all  these  methods,  extraction  on  one  or  both  legs  is  by  far  the  best,  and  I 
have  not  yet  met  a  case  where  it  was  impossible  to  get  a  foot  down.  Deep  anes- 
thesia and  the  Trendelenburg  posture  have  always  enabled  me  to  reach  the  extrem- 
ity, no  matter  how  firmly  the  breech  seemed  wedged  into  the  pelvis  at  the  start. 
In  cases  of  contracted  pelvis,  unless  cephalic  version  is  to  be  performed,  it  is  advis-

on  the  anterior  scapula,  and  the  other  fingers  being  evenly  distributed  over  the  thorax.  Then,  with  gentle  rotation  the 
anterior  arm  is  turned  to  the  back,  following  the  direction  of  the  child'a  belly,  and  the  now-posterior  second  arm'and

able  to  bring  down  the  foot,  and  in  pendulous  abdomen  it  is  also  desirable,  the  leg 
straightening  out  the  child  in  the  axis  of  the  inlet,  which  permits  the  uterus  to 
work  to  good  advantage.  In  single  breech  presentations  the  manct^uver  is  the 
hardest  to  carry  out;  in  double  jjreech,  two  fingers  may  be  al:)le  to  grasp  the  ankle, 
which  lies  near  the  internal  os.  The  anterior  limb  is  to  be  selected  whenever  pos- 
sible, because  this  brings  the  back  to  the  pubis,  but  if  too  much  trouble  is  experi- 
enced, the  posterior  one  is  seized,  and  in  the  subsequent  extraction  due  notice  is 
taken  of  the  mechanism  intended  by  nature. 


950 


OPERATIVE    OBSTETRICS 


Delivery  by  the  finger  in  the  groin  is  the  least  harmful  of  all  the  other  methods 
mentioned,  which  possess  real  dangers  of  injuring  tlu^  skin,  vessels,  and  nerves  in 
the  groin  and  of  fracturing  the  neck  of  the  femur.  The  blunt  hook,  the  fillet,  the 
breech  forceps,  and  the  head  forceps,  in  my  opinion,  should  be  used  only  on  a  dead 
fetus.  But  very  few  authorities  recommend  them,  and  in  my  practice  so  far 
they  have  been  entirely  dispensable.  Barnes,  in  his  immense  experience,  never 
failed  to  bring  do^ATi  a  leg. 

The  second,  third,  and  fourth  acts  of  extraction  have  been  fully  described  under 
IManual  Aid  (q.  v.,  p.  947). 

It  remains  to  discuss  the  chfficulties  that  are  likely  to  arise  during  the  extraction. 


Fig.  837. — Wiegaxd-Martin  ISIethod  of  Delivering  the  After-coming  Head. 
Remembering  the  mechanism  of  breech  labor,  the  accoucheur  will  know  on  which  side  of  the  pelvis  the  mouth  will 
be.  The  hand  whose  palm  applies  to  the  belly  searches  for  tlie  child's  mouth,  and  two  fingers  are  passed  into  it  until 
they  come  to  rest  at  tlie  posterior  angles  of  the  jaw,  the  child  lying  on  the  forearm.  Standing  to  the  patient's  side, 
the  accoucheur  places  the  other  hand  on  the  head  from  the  outside  (having  carefully  pushed  the  intestines  out  of  the 
way),  and,  by  combined  pressure  from  above,  with  very  light  traction  from  below,  the  head  is  brought  down  into  the 
pelvis,  rotated,  and  delivered,  following  the  mechanism  usually  adopted  by  nature.  The  chin  is  kept  well  flexed,  and 
when  the  nape  of  the  neck  stems  behind  the  pubis,  the  chin,  face,  forehead,  and  vertex  are  brought  slowly  over  the 
perineum.     In  primiparse  episiotomy  is  usually  performed. 


Two  facts  require  emphasis  at  the  very  start.  One  is  that  the  mechanism  of  breech 
labor  may  be  pathologic  throughout  its  whole  course,  or  may  rectify  itself  at  any 
point,  and  a  normal  mechanism  may  become  pathologic  at  any  point.  The  other 
is  that  when  an  extraction  is  done  to  save  the  child,  the  conditions  for  delivery 
must  be  insisted  upon,  especially  the  one  relating  to  the  complete  dilatation  of  the 
cervix.  To  force  the  delivery  through  an  ill-prejiared  cervix  is  to  expose  the  mother 
to  the  greatest  danger  of  rupture  of  the  uterus,  and  for  so  much  hazard,  in  all 


OPERATIONS    OF    DELIVERY

probability,  lose  the  child.  The  rigid  cervix  delays  the  extraction  so  long  that  the 
child  succumbs,  unless  the  accoucheur  is  prepared  to  make  deep  incisions  into  the 
constnctmg  structures.

babies  it  is  wise  to  deliver  the  arms  before  the  shoulders  have  become  wedged  into 
the  pelvis,  therefore,  not  to  draw  the  trunk  down  until  the  scapula  is  palpable  under 
the  pubis,  but  to  begin  the  third  act  sooner. 

During  the  Third  Act. — Normally,  the  arms  lie  crossed  over  the  chest,  and  if 
nothing  interferes,  are  delivered  in  this  position.  If  traction  is  made  on  the  body 
too  soon;  if  the  pelvis  is  small;  if  the  cervix  is  not  sufficiently  dilated^ — the  arms 
may  be  arrested  and  stripped  up  above  the  child's  head  (Fig.  842).  In  such  cases 
it  is  necessary  to  pass  the  four  fingers  high  into  the  pelvic  inlet,  leaving  the  thumb 
outside,  and,  as  usual,  gliding  over  back,  shoulder,  humerus,  elbow,  to  the  forearm;

and  out.  The  posterior  arm  is  first  delivered.  Episiotomy  is  the  rule  in  primiparae, 
because  the  thickness  of  the  hand  added  to  that  of  the  chest  is  usually  too  much  for 
the  perineum.  It  may  be  well  to  push  the  child  back  a  little  to  loosen  the  arms 
from  the  wedge-like  action  of  the  head.     If  it  is  too  hard  to  get  the  posterior  arm, 


Fig.  841.— Delivery  of  Breech  with  Finger  in  Groin.  Other  Hand  Supports  Wrist. 
In  extracting  the  breech  with  one  finger  in  the  anterior  groin  the  whole  hand  is  placed  in  the  vagina,  the  finger 
passes  from  in  front,  while  the  thumb  seeks  to  aid  a  better  grasp  on  tlie  pelvis.  Traction  is  to  be  made  downward, 
but  the  pull  must  be  toward  the  belly  of  the  child,  to  avoid  injury  to  the  structures  in  the  inguinal  region  and 
fracture  of  the  femur.  This  operation  is  very  tiring,  hence  the  hands  may  be  changed  and  the  wrist  supported  as 
shown.  Episiotomv  and  patience  are  required.  As  soon  as  the  posterior  groin  is  accessible,  the  index-fanger  of  the 
other  hand  is  placed  in  it,  and  delivery  of  the  breech  accomplished  easier. 

the  child  may  be  rotated  ventrally  so  as  to  bring  the  anterior  arm  to  the  hollow 
of  the  sacrum,  and  this  arm  is  hberated  first,  then  the  trunk  is  rotated  back  for  the 
first  arm.  If  the  operator's  fingers  are  short,  or  if  the  arm  is  very  high  up,  the  whole 
hand  should  be  passed  in  to  get  the  arms.  Then  the  thumb  should  lie  parallel  to, 
never  opposed  to,  the  fingers,  and  it  may  not  be  used  to  grasp  the  arm.     During 


954  OPERATIVE    OBSTETRICS 

these  manipulations  the  assistant  should  not  exert  pressure  on  the  fundus  uteri, 
since  this  renders  internal  manipulation  difficult. 

A  second  and  a  bad  complication  occurs  in  the  third  act,  when  the  arms  are 
thrown  back  into  the  nape  of  the  neck  and  cross  the  pelvis  under  the  head.  This 
is  usually  caused  by  anomalous  rotation  of  the  child's  trunk,  and  is  commoner  after 
version  and  improper  efforts  at  extraction  (Fig.  843).  This  condition  is  recognized 
only  when  the  fingers  are  passed  in  to  liberate  the  posterior  arm.  Without  delay 
the  body  of  the  child  is  pushed  back,  or  stuffed  in  a  few  inches,  to  release  the  arms 
from  their  imprisonment  by  the  head,  and  the  half  hand  inserted  directly  up  the 
child's  back  to  the  forearm.  This,  then,  is  pushed  up,  the  fingers  wiping  the  baby's 
elbow  and  forearm  over  its  face,  past  the  sacral  promontory  to  the  other  half  of 
the  pelvis,  do^\Ti  and  out.  If  this  does  not  succeed  the  first  time,  the  child  should 
be  pushed  back  a  little  further  and  the  manceuver  tried  once  more,  failing  which  the 
anterior  arm  should  be  liberated.     Grasping  the  chest  as  indicated  in  Fig.  836,  p. 


Fig.  S42. — Arms  Stripped  Up.     Whole  Hand  Required  to  Bring  Them  Down. 
The  thumb  may  not  be  used  to  grasp  the  arm. 

949,  the  child  is  rotated  ventrally  so  as  to  bring  the  anterior  arm  behind;  then, 
with  four  fingers  deeply  inserted,  or  even  the  whole  hand,  the  just  mentioned  motion 
with  the  child's  forearm  is  carried  out.  Rotation  of  the  trunk  much  facilitates 
the  release  of  the  arm. 

It  is  not  allowable  to  pull  down  on  the  shoulder  to  make  the  arm  and  elbow 
more  accessible.  Fracture  of  the  clavicle  is  the  certain  result.  Nor  may  the  arm 
be  brought  down  over  the  back,  obviously,  for  the  same  reason.  If  the  accoucheur 
will  go  at  his  work  deliberately,  it  will  not  be  needful  to  exert  brute  force  and  break 
the  clavicle  or  humerus.  To  try  to  deliver  the  head  without  pr(^vious  liberation 
of  the  arms  (Deventer)  is  not  good  practice. 

Kiistner  recommended,  where  difficulty  is  apprehended,  to  bring  down  one 
arm  immediately  after  the  navel  appears,  and  Guffey  advises  this  for  all  breech 
cases.  In  version  cases  it  is  good  practice  to  put  a  sling  on  one  arm  prophylac- 
tically. 


OPERATIONS    OF   DELIVERY 


955 


During  the  Fourth  Act. — Arrest  of  the  head  may  occur  at  the  pelvic  inlet,  and 
after  it  is  in  tlie  excavation  or  at  the  outlet.  If  the  child  is  large  or  the  pelvis  small, 
the  head  wedges  into  the  inlet  with  the  sagittal  suture  in  the  transverse  diameter. 
Extension  occurs  and  the  mouth  is  throA\'n  up  high — sometimes  above  the  brim. 
Treatment:  Wiegand-]\Iartin's  method,  remembering  that  the  chin  is  high  up  and 
to  the  side,  that  the  head  must  be  brought  through  the  inlet  in  the  transverse 
diameter,  that  it  should  not  l^e  stronglj-  flexed,  and  that  it  may  not  be  rotated  to 
bring  the  occiput  forward  until  it  is  deep  in  the  excavation.  The  pull  must  be 
downward  in  the  axis  of  the  inlet,  hence  the  patient  is  best  on  a  high  table,  but 
most  of  the  work  is  to  be  done  by  pressure  with  the  outside  hand.     Where  this

method  fails,  the  Mauriceau-Smellie-Veit  method  is  tried  (Fig.  844).  One  hand 
searches  the  mouth,  and  two  fingers  are  placed,  as  before,  on  the  lower  insertions  of 
the  pterygomaxillary  ligaments.  The  other  hand  is  placed  fork-like  over  the 
shoulders,  with  the  finger-tips  resting  on  the  sternum,  not  on  the  sides  of  the  neck. 
The  knuckles  rest  against  the  mastoid  processes.  While  an  assistant  presses  the 
head  forcibly  downward  from  without,  the  operator  pulls  gently,  but  firmly,  down- 
ward from  within,  observing  the  mechanism  just  described.  In  particularly  diffi- 
cult cases  the  Walcher  position  may  be  used,  and  the  operator,  by  pushing  the  head 
to  one  or  the  other  side  of  the  promontory,  may  gain  more  room  for  the  large  bipa-

If  the  head  will  not  come  into  the  pelvis  under  the  exhibition  of  moderate  torce 
applied  above  and  below,  it  is  best  to  desist,  because  the  end  sought,  a  living  child, 
will  be  defeated  bv  the  attempt  itself,  and  the  mother  will  suffer  irreparable  injury. 
Now  there  is  no  occasion  for  hurry.     Craniotomy  should  be  performed.     In  prac-

tice  there  is  usually  no  compunction  about  such  a  course,  since  the  child  has  almost 

always  died  by  this  time.  i  .    ,  •  ,  •     .u 

Forceps,  useful  later,  are  hardly  applicable  when  the  head  is  high  up  m  the 
inlet      Thev  are  then  dangerous  to  the  mother  and  barren  of  results. 

When  the  head  is  arrested  in  the  excavation,  a  quick  examination  determines 
if  the  delav  is  caused  by  the  cervix  or  by  the  bony  pelvis.  A  tight  cervix  must  be 
stripped  back  or  cut,  which  is  not  always  a  simple  matter.  If  the  methocls  ot 
deliverv  just  mentioned  do  not  show  immediate  results,  the  forceps  should  be 
applieci  to  the  after-coming  head.     My  practice  for  years  has  been  to  apply  forceps 


958 


OPERATIVE    OBSTETRICS 


to  the  after-coming  head  if  it  docs  not  quickly  follow  moderate  traction,  and  Kerr 
recommends  it  very  highly,  quoting  also  Smellie,  Barnes,  and  Hermann  in  its  favor. 
"Williams  opposes  the  practice,  as  do  some  of  the  German  authorities,  though  several 
— Nagel,  Klien,  Kehrer,  Cretle,  and  others,  and  French  operators.  Bar  and  Tarnicr — 
employ  the  instrument  in  some  cases.  I  am  convinced  that  many  children  will  be 
saved,  that  fracture  of  the  clavicle,  hematoma  of  the  sternomastoid,  dislocation  of 
the  vertebrae,  Erb's  paralysis,  and  many  lesser  injuries  could  be  avoided  if  the 
application  of  the  forceps  to  the  after-coming  head  Avere  taught  in  the  schools  and 
more  generally  practised.  It  is  a  more  humane  way  of  delivering  the  head  in  cases 
of  moderate  difficulty  than  the  Mauriceau-Smellie-Veit  method.  At  least,  in  all 
breech  cases  the  forceps  should  be  ready  for  use. 

A  very  valuable  manceuver,  practised  for  many  centuries,  is  the  retraction  of  the

perineum  by  the  hands  or  by  broad  specula,  wiping  the  vagina  dry  and  allowing 
the  child  to  breathe  with  its  head  still  in  the  pelvis  (Fig.  846).  A  stiff  rubber  tube 
may  also  be  inserted  into  the  child's  pharynx.  Stowe,  in  one  case,  did  tracheotomy 
and  saved  the  infant. 


Abnormal  Rotation  in  Breech  Cases. — Thus  far  we  have  considered  the  operation  of  delivery 
when  the  nieciianism  of  laljor  has  lx>en  the  usual  one — that  is,  with  the  back  anterior.  Just  as 
in  vertex  presentations,  we  liave  errors  in  the  mechanism  due  to  abnormal  rotation.  In  some 
breech  dehveries  the  child's  back  turns  to  the  mother's  back,  and  the  l)elly  lies  forward,  behind 
the  pubis.  This  complication  occurs  oftener  in  footling  presentations  when  the  posterior  leg 
has  come  down,  after  version  when  the  operator  has  seized  the  posterior  leg,  and,  rarely,  during 
an  otherwise  natural  breech  labor  when  improper  attempts  at  rotation  had  been  made.  As  was 
said  in  discussing  breech  presentation,  nature  almost  always  rectifies  the  abnormal  start  of  the 
mechanism  by  turning  the  back  three-fourths  of  a  circle,  making  it  rotate  the  "long  route," 
past  the  promontory,  through  the  other  half  of  the  pelvis  to  the  front.  The  l)ack  rotates  in  the 
direction  opposite  from  that  which  one  would  expect.  An  acute  observer  will  notice  this  tendency 
of  the  breech  to  swing  around  in  front  of  the  sacrum,  liy  not  appreciating  this  point  and  resist- 
ing the  mechanism  sought  by  nature,  the  accoucheur  may  cause  the  back  to  remain  directed 
behind.  During  the  first  and  second  acts  this  is  of  little  moment.  Watching  the  rotation  intended 
by  nature,  the  operator  seeks  to  aid  it  by  pulling  harder  on  that  groin  which  tends  to  turn  forward. 


OPERATIONS    OF    DELIVERY 


959 


In  a  few  cases,  even  when  the  posterior  limb  is  down,  the  back  takes  the  "short  route,"  through 
one-fourth  of  a  circle,  to  the  pubis. 

Abnormal  Rotation  During  the  Third  Act. — The  arms  may  lie  folded  across  the  chest,  may  be 
stripped  up  alongside  the  head,  or  may  be  crossed  in  the  nape  of  the  neck.  In  the  first  case  the 
matter  is  very  simple.  The  child  is  supported  a  little  above  the  horizontal  with  one  hand,  while 
two  fingers  of  the  other  go  in  over  the  back,  over  the  shoulder,  down  the  arm  to  the  elbow,  and 
wipe  the  forearm  over  the  chest,  out  from  behind  the  pubis,  the  usual  mana'uvcr  being  reversed. 
It  may  also  be  possible,  sinking  the  trunk  toward  the  floor,  to  go  directly  to  the  forearm  from 
behind  the  pubis,  and,  indeed,  this  may  be  the  only  way  if  the  child  is  large  or  the  pelvis  small — 


Fig.  848. — Rotating  Head  by  Conjoined  Manipulation. 


there  may  be  no  room  behind.  When  the  arms  are  stripped  up  above  the  head,  great  difficulties 
are  usually  met,  and  if  they  are  in  the  nucha,  it  may  be  impossible  to  liberate  them  without 
fracture.  Under  no  conditions  may  the  arms  be  brought  down  over  the  child's  back.  In  the 
first  place,  if  the  accoucheur  sees  that  the  cliild's  back  remains  persistently  posterior,  he  will 
bring  the  arms  down  as  early  as  possible.  It  is  sometimes  necessary  to  pass  the  whole  hand  into 
the  parturient  canal  in  order  to  reach  the  arms — especially  if  the  accoucheur  has  short  fingers. 
This  overdistends  the  vagina  and  perineal  floor,  hence  a  deep  episiotomy  is  made,  as  a  rule.  Some 
authors  recommend  that  the  arms  be  brought  down  after  sinking  the  child's  trunk  and  entering 
and  operating  beliind  the  pubis.  I  prefer,  with  Fritsch  and  the  majority,  to  raise  the  body  of  the 
child  somewhat  (one  cannot  pull  it  up  so  far  as  when  the  back  is  anterior),  and  pass  the  four 


960 


OPERATIVE    OBSTETRICS 


fingers  from  behind  up  to  the  head  and  push  the  forearm  forward  and  to  the  opposite  anterior 
quadrant  of  the  pelvis,  then  down  over  the  ehest,  as  in  Fig.  847.  If  the  first  attempt  does  not 
succeed,  the  trunk  of  the  cliild  is  rotated,  at  the  same  time  stuffing  it  back  somewhat  to  free  tiie 
arms  above  the  inlet,  and  the  anterior  arm  is  delivered  first.  The  child  is  now  turned  back  for 
the  other  arm  to  come  behind.  Pulling  on  the  shoulder  to  make  the  arm  more  accessible  fractures 
the  clavicle.  In  a  few  cases  I  was  able  to  aid  the  internal  hand  by  letting  an  assistant  support 
the  body  of  the  child,  while  I  pushed  the  arms  into  proper  position  from  the  outside.  External 
manipulation  is  not  used  enough  in  our  obstetric  operations.  In  only  one  case  from  a  very  large 
number  was  I  constrained  delilierately  to  br(>ak  the  arm  in  order  to  pres(!rve  the  life  of  the  child, 
which  was  jeopardized  by  the  delays  in  the  d(>livery.  It  is  wise  to  announc(>  this  necessity  before- 
hand. A.  Miiller's  pi'ocedure,  delivery  of  the  shoulder-girdle  without  previous  liberation  of  the 
arms,  is  not  to  be  recommended  since  fractures  of  the  extremities  and  rupture  of  the  spinal 
column  are  very  common.     The  operation  is  not  artistic,  but  brutal. 

During  the  Fourth  Act. — Referring  to  the  chapter  on  Abnormal  Mechanisms  with  Breech, 
it  will  be  found  that  the  head  may  be  arrested  at  the  inlet  with  the  chin  caught  over  the  ramus 
pubis,  or  the  head  may  engage  in  the  pelvis  with  the  chin  to  the  front,  and  that  nature  may  ter- 
minate these  cases  in  two  ways — one  is  by  flexion:  the  body  depends,  the  chin  remains  applied 
to  the  sternum,  and  the  face,  forehead,  and  vertex  roll  out  from  beliind  the  pubis,  the  nape  of  the

neck  resting  on  the  perineum;  the  other  is  by  extension:  the  chin  leaves  the  sternum,  and  if  the 
child  is  lifted  up  to  the  belly  of  the  mother,  the  occiput,  vertex,  and  face  come  over  the  perineum, 
the  neck  resting  behind  the  pubis,  and  the  face  issuing  the  very  last. 

In  the  first  (lase  the  accoucheur  may  attempt  to  turn  the  head  so  as  to  bring  the  occiput  to 
the  front,  the  chin  to  the  rear  or  to  the  side,  if  the  pelvis  is  a  flat  (iontrac^ted  one.  LaChapelle 
passed  the  hand  in  on  the  side  opposite  that  on  which  the  chin  lay  and  tried  to  pull  the  face  around. 
Zwcnfel  recomnuMided  pressure;  with  four  fingers  on  the  upi)er  jaw.  In  four  cases  the  following 
mano-uver  succeeded  (juickly:  Two  fingers  behind  the  pubis  ol)tain('d  a  i)urchase  on  the  malar 
bone,  and,  while  i)ushing  this  to  the  reai',  the  outside  hand  pulled  the  occiput  to  tlu;  front  (Fig.  848). 
Now  the  mouth  was  readily  accessible,  and  the  usual  me(!hanism  could  l)e  carried  out.  In  another 
case  I  pushed  the  chin  to  the  side  with  the  outside  hand,  while  the  inside  hand  pulled  the  occiput 
to  the  front. 

If  rotation  of  the  head  does  not  fiuickly  take  place,  it  may  be  b(;tter,  since  seconds  are  very 
valuable,  to  try  to  deliver  the  head  without  turning  the  chin  behind.  Van  lloorn's  method  is 
used  if  the  occiput  has  not  engaged  in  tlu;  pelvis,  combined  with  pn^ssurt;  on  the  forehead  from  the 
outside  (Fig.  849).  This  pressure  should  do  most  of  the  work.  The  child  is  lifted  up  over  the 
pubis,  to  which  its  chest  applies,  and  thus  the  occiput  rolls  past  the  promontory  into  the  hollow 
of  the  sacrum.  Too  much  force  exerted  now  will  break  tlie  child's  neck.  When  the  occiput  comes 
into  the  hollow  of  the  sacrum,  the  accoucheur  quickly  determines  if  the  mouth  of  the  infant  ia 


OPERATIONS    OF    DELIVERY  961 

accessible  behind  the  pubis— that  is,  if  extension  or  flexion  is  present.  If  the  finger  can  be  inserted 
into  the  mouth,  the  Mauriceau-SmelUe-Veit  method  upside  down  is  performed;  if  extension  has 
occurred,  the  chin  lying  above  the  pubis,  a  mo(hfied  Van  Hoorn's  method  is  practised.  I  believe 
the  forceps  would  l)e  preferaljle  to  either  of  these  manoeuvers.  Ind(>ed,  the  necessity  for  them  is 
of  the  greatest  rarity,  since  it  is  almost  always  possible  to  bring  the  head  down  in  proper  rotation. 

A  complete  extraction  by  the  breech,  if  properly  executed,  is  one  of  the  most 
brilliant  operations,  and,  if  the  complications  are  successfully  mastered  without 
injury  to  the  mother  or  child,  it  takes  rank  with  the  technically  most  difficult  of  all 
surgery.  Every  motion  is  the  result  of  centuries  of  study  and  practice  by  the 
world's  best  accoucheurs,  and  the  movements  must  follow  each  other  with  deliber- 
ation, exactness,  and  speed.  Four  minutes  are  allowed  for  the  arms  and  four  for 
the  head.  More  time  consumed  endangers  the  child.  It  is  a  good  plan  for  an 
assistant  to  count  aloud  the  minutes.  While  a  child  may  live  five  minutes  after 
its  placental  circulation  is  cut  off,  it  is  greatly  endangered,  and  may  die  later  of 
atelectasis,  pneumonia,  sepsis,  or  the  results  of  profound  asphyxia. 

Finally,  attention  should  be  drawn  to  complications  offered  Ijy  the  soft  parts. 
If  extraction  is  undertaken  before  the  cervix  is  fully  dilated,  dangers  of  no  mean 
order  are  incurred  for  both  mother  and  child.  For  the  mother  there  is  risk  of  tears 
of  the  lower  uterine  segment  and  cervix,  which  in  placenta  prsevia  are  particularly 
fatal  from  hemorrhage.  Sepsis  is  a  later  result.  For  the  child  the  risk  lies  in  the 
delay  incident  to  the  stripping  up  of  the  arms  by  the  tight  ring  of  the  cervix,  and,  too, 
even  after  liberation  of  the  arms  the  cervix  may  close  down  around  the  neck  and 
face,  at  the  root  of  the  nose,  buttonholing  the  head  in  the  uterus.  Traction  in 
such  cases  brings  the  constricting  cervix  into  view  as  a  thick,  purplish  and  white 
band.  This  ring  may  be  carefully  stripped  back,  or  if  too  tight,  may  be  incised. 
It  may  be  possible  to  admit  air  to  the  child's  mouth  by  means  of  specula  and  wait 
for  the  head  to  come  through  (Fig.  846,  p.  957). 

Deep  lacerations  of  the  perineum,  even  to  the  third  degree,  are  very  common  in 
breech  deliveries.  They  occur  when  the  hand  is  inserted  alongside  the  trunk  or 
during  the  rapid  delivery  of  the  head.  I  make  an  extensive  episiotomy  in  most 
breech  cases,  not  alone  to  preserve  the  sphincter  ani,  but  also  to  facilitate  all  the  re- 
quired manipulations,  which  save  the  child  from  asphyxia  and  from  injury. 

Lack  of  space  prevents  reference  to  the  many  accoucheurs  who  perfected  each 
of  the  various  manoeuvers  above  detailed.  The  history  of  the  operation  of  breech 
extraction  may  be  found  in  the  Edgar- Winckel  Text-book  of  Obstetrics. 


FORCEPS 

Definition. — The  forceps  of  obstetrics  is  an  instrument  designed  to  extract 
the  fetus  by  the  head  from  the  maternal  passages,  without  injury  to  it  or  to  the 
mother.  As  soon  as  the  right  of  either  is  encroached  upon,  the  instrument  ceases 
to  be  the  forceps  of  obstetrics,  but  becomes  simply  an  instrument  of  extraction, 
similar  to  the  craniotomy  forceps,  and  not  so  good. 

History. — Hippocrates  advised  pulling  on  the  head  with  the  hands,  but  probably  used  the 
manoeuver  only  for  small  heads;  the  Arabians  used  a  three-  or  four-bladed  hooked  tractor  for 
dead  fetuses;  in  1554  Rueff,  of  Ziirich,  published  a  jointed  forceps  similar  to  that  used  in  lithot- 
omy; in  1561  Pierre  Franco  advised  a  three-bladed  duckbill  speculum,  obviously  impractical; 
the  Japanese  for  centuries  used  whalel:)one  loops  and  silk  nets  brought  over  the  head  by  means 
of  strips  of  whalebone;  Smellie  tried  to  draw  fillets  over  the  occiput  and  chin.  It  is  remarkable 
that  the  idea  of  the  obstetric  forceps  was  so  long  in  coming  As  Schroder  says,  this  was  probably 
because  men  were  not  allowed  at  the  confinement-bed  except  in  the  most  difficult  cases  And 
here,  for  lack  of  experience  in  normal  cases,  they  knew  little  except  to  mutilate  the  child  and  extract 
it,  and  often  tlie  viscera  of  the  mother,  with  sharp  liooks.  Unless  the  cliild  presented  by  the  breech 
or  shoulder,  so  that  the  accoucheur  could  grasp  a  leg  on  which  to  pull,  he  was  powerless,  except  as 
stated.  Small  wonder  the  women  took  alarm  when  a  "man-midwife"  had  to  be  called,  because 
they  had  observed,  says  Smellie,  that  "either  the  mother  or  the  child  or  both  were  lost." 

In  1720  Palfyn,  of  Ghent,  laid  before  the  Academy  of  Medicine  in  Paris  his  forceps  (Fig. 
850)  for  the  extraction  of  the  child  without  mutilation.  This  rough,  clumsy  instrument  was

modified  by  others.     Dusse  crossed  the  blades  and  lengthened  them,  and  Levret,  1746   added 
the  pelvic  curve,  also  the  French  lock,  still  used,  though  modified.  ' 

The  first  forceps  were  invented  probably  in  loSO'bv  Peter  Chamberlen,  the  elder,  the  son  of 
a  Huguenot,  Wilham  Chamberlen,  who  fled  from  Paris  in  1569  and  settled  in  Southampton. 
In  1670  Hugh,  one  of  the  large  family,  went  to  Paris  and  tried  to  sell  the  instrument  for  .?750o! 
IMauriceau,  to  test  the  value  of  Chamberlen's  pretenses,  suggested  that  the  latter  attempt  the 
delivery  of  a  woman  with  extreme  contraction  of  the  pelvis,  upon  whom  he  had  decided  to  perform

room  set  about  the  task  After  three  hours  of  vain  effort  he  was  obligeil  to  acknowledge  his

he  lied  to  Holland,  where  he  sold  the  secret  to  a  Roonhuysen,  in  Amsterdam,  who  sold  it  in  turn 
to  any  doctor  having  the  necessary  large  amount  of  money,  but  sold  onlv  half  the  forceps,— 
the  vecti.s,— adding  fraud  to  infamy.  "

through  Palfyn,  Drinkwater,  and  others,  the  forceps  had  become  common  property.  Palfyn  died 
poor  and  neglected,  but  in  1784  his  resting-place  in  Ghent  was  marked  by  a  statue  of  a  weeping 
woman.  The  original  forceps  of  the  Chamberlens  were  found  in  1815  in  a  hidden  attic  of  a  house 
in  E.ssex,  England,  occupied  by  several  generations  of  the  family  (Ingraham) .  Numberless  altera- 
tions and  modifications  have  been  made  on  the  forceps.  Fig.  850  shows  a  few  of  them,  the 
only  radical  changes  from  the  original  Chamberlen  and  Dusse  models  being  the  addition  of  axis- 
traction  by  Tarnier  in  1877. 

Description. — The  forceps  consists  of  two  blades,  which  are  named  right  and 
left,  according  to  the  side  of  the  mother's  pelvis  in  which  they  he  when  applied. 
Each  blade  has  a  handle  and  a  hook-like  projection,  added  by  Busch.  Gregoire 
(1740)  put  the  fenestrmn  in  the  blade,  but  the  Chamberlen  forceps  also  had  it. 
Some  of  the  latest  forceps  are  unfenestrated,  for  example,  the  McLane-Tucker. 
The  blades  are  curved  on  the  flat  to  fit  the  head, — the  "cephalic  curve," — and  on 
the  edge  to  fit  the  conca^^t3'  of  the  sacrum — the  "pelvic  curve."  The  two  blades 
are  fitted  together  by  a  lock,  which  in  the  English  forceps  consists  of  opposing 
shoulders  with  a  flange;  in  the  French  forceps,  a  screw  or  pin;  and  in  the  German 
instrument,  a  sort  of  combination  of  both  principles.  Smellie  and  the  English  used 
a  very  short  forceps,  because  the  operation  was  practised  only  after  the  head  was 
well  down  in  the  pelvis.  The  French  used  long  forceps,  since  they  often  extracted 
the  head  before  engagement  had  occurred.     The  German  forceps  is  rather  long,

and  resemble  the  French  in  having  a  small  cephalic  curve  and  a  marked  pelvic 
curve. 

I  have  found  that  the  best  forceps  for  general  use  is  the  one  of  Simpson,  as 
adopted  by  the  Viemia  School,  often  called  the  Viemia  School  forceps  (Fig.  851). 
I  made  the  hooks  larger  and  flatter,  so  as  not  to  hurt  the  hand,  and  modified  the 
handles  a  little  to  secure  lightness  and  ease  of  cleansing,  but  the  essentials  of  the  in- 
strument are  unchanged. 

The  function  of  the  forceps  is  simply  one  of  traction,  as  Levret  pointed  out  in 
1746.  Some  irritation  of  the  uterus  ensues  after  the  blades  are  in  place  and  may 
evoke  pains.  This  is  the  so-called  "djmamic  action."  An  attempt  to  strengthen 
this  very  uncertain  action  by  the  aid  of  the  faradic  current  was  made,  but  failed. 

The  forceps  is  not  a  rotator,  in  the  strict  sense  of  the  term — that  is,  the  instru- 
ment may  not  be  used  to  t\\ist  the  head  from  one  position  to  another,  for  example, 
from  an  occipitoposterior  to  occipito-anterior.  Such  motions  tear  the  vagina  off  its 
pelvic  attachments  or  even  open  the  bladder.  A  certain  amount  of  rotation  may 
sometimes  be  given  the  head,  together  with  horizontal  traction,  the  movement 
being  thus  a  turbinal  or  spiral  one.  This  distinction  is  highly  important.  Even 
the  turbinal  movement  endangers  the  soft  parts  to  an  extent. 

As  a  lever,  the  forceps  may  also  not  be  used,  that  is,  pendulum  motions  are  not 
permissible.  The  maternal  soft  parts  are  then  the  fulcrum,  and  will  be  bruised  and 
torn.     Levering  and  twisting  are  not  observed  in  nature. 

Compression  of  the  head  is  inevitable,  but  we  seek  to  reduce  it  to  the  minimum. 


964 


OPERATIVE    OBSTETRICS 


Experiments  have  proved  what  a  Httle  reflection  would  show,  that  we  can  reduce 
the  volume  of  the  fetal  head  but  a  few  cubic  millimeters  by  means  of  outsule  force, 
and  even  this  is  attended  by  great  danger  to  the  child.  If  one  applies  forceps  to  the 
head  of  a  still-born  child  in  mannikin  practice,  it  will  be  observed  that  closmg  the 
blades  causes  the  head  to  bulge  out  in  the  diameter  at  right  angles  to  the  direction 
of  compression,  Init  onlv  slightly.  What  is  more  noticealile  is  the  lengthening  of 
the  head  in  its  long  diameter,  a  point  which  Levret,  Baudeloc(iue,  Budin,  and  :\Iilne- 


Fig.  852. — Experiment  to  Show  Compression  Effect  of  Traction. 

Murray  refer  to.  Much  depends  on  the  softness  of  the  head  and  the  shape  of  the 
canal  through  which  it  is  to  pass.  Reference  to  Fig.  852  will  show  how  the  head 
suffers  compression  in  three  ways.  By  squeezing  the  handles  of  the  forceps  to- 
gether at  P",  the  action  is  that  of  a  lever  of  the  first  class,  the  lock  being  the  ful- 
crum, F,  the  resistance  being  the  head,  R.  Traction  downward  at  P'  acts  in  the 
same'way,  but  since  the  pull  is  on  the  short  arm  of  the  lever,  the  pressure  at  R  would 
be  less,  were  it  not  that  in  practice  we  put  on  more  tractive  force  at  P'  than  we 
do  compressive  force  at  P".     The  sum  of  the  two  compressions,  however,  must  be 


OPERATIONS    OF   DELIVERY  965 

considerable.  The  compression  at  P"  we  can  regulate  ourselves,  but  the  amount 
exerted  at  P'  depends  entirely  on  the  amount  of  pull  exerted  to  deliver  the  head. 
A  third  source  of  compression  is  the  resultant  of  the  pull  of  the  forceps  against  the 
bony  pelvis  or  the  soft  parts,  that  is,  any  resistance.  Here  again  power  is  applied 
at  P',  or,  as  is  advised  in  practice,  at  F,  but  the  fulcrum  is  at  X,  and  the  power  is 
applied  to  the  long  arm  of  the  lever,  obviously  the  most  dangerous  circumstance 
for  the  fetal  head.  This  item  of  compression  increases  with  the  resistance  met. 
Taking  these  facts  into  consideration,  I  must  disagree  with  Barnes,  believing  that 
the  compression  is  not  one-half  of  the  power  of  the  traction,  but  probably  greater 
than  the  traction.  Compression  of  the  head  has  very  noxious  influences  on  the 
brain.  If  suddenly  applied,  the  child  suffers  from  concussion.  If  slower  in  action, 
the  circulation  is  hindered,  the  pneumogastric  is  stimulated,  the  pulse  being  slowed, 
and  asphj'xia  resulting,  or  smaller  or  larger  hemorrhages  occur — all  these  outside  of 
direct  injury  to  structure  or  fracture  of  the  bones.  Children  vary  very  much  in 
their  ability  to  stand  compression.     Some  seem  to  have  charmed  lives. 

Traction,^simple  traction, — then,  is  the  dominant  function  of  the  forceps. 
It  supplies  from  below  the  force  which  is  lacking  from  above,  and  our  art  enaljlcs 
us  to  apply  this  traction  to  the  best  advantage.  How  much  traction  may  safely 
be  applied  is  hard  to  say.  Attempts  to  measure  it  with  dynamometers  have  failed. 
It  is  rarely  necessary  to  pull  with  more  than  the  strength  of  the  biceps,  as  in  Fig. 
860.  To  brace  the  feet  against  the  table  and  pull  with  all  the  strength  of  the  back 
and  shoulders  is  brutal,  unscientific,  and  murderous.  Craniotomj'  is  more  humane. 
The  accoucheur  should  always  remember,  when  working  \\ath  the  forceps,  that  he 
has  a  child's  brain  in  the  grasp  of  a  powerful  vise,  and  that  only  the  greatest  care 
and  gentleness  will  save  its  wonderfully  delicate  structure  from  injury. 

Indications  for  Forceps. — These  are  the  same  as  for  extraction  in  general,  com- 
prising those  conditions  which  threaten  the  hfe  of  the  mother  or  child.  Some 
accoucheurs  apph'  the  forceps  as  soon  as  the  head  reaches  the  perineum,  wdth  the 
sole  object  of  saving  the  woman  the  pain  of  the  second  stage.  This  practice  is  to 
be  deprecated,  but  at  the  same  time  it  is  cruel  to  allow  the  woman  to  remain  many 
hours  in  the  second  stage,  waiting  for  signs  of  actual  danger  to  the  mother  or  child, 
when  the  accoucheur  is  convinced  that  she  wall  not  be  able  to  deliver  herself.  As 
Barnes  said,  we  should  wait  to  see  what  the  woman  is  able  to  accomplish,  not  what 
she  can  endure.  Then,  too,  when  the  signs  of  danger  to  the  mother  or  the  child 
are  present,  often  real  damage  has  been  done-^it  were  "uiser  if  the  accoucheur  had 
anticipated  the  dangers.  In  America,  75  per  cent,  of  the  forceps  operations  are 
done  because  of  insufficiency  of  the  powers  of  labor  when  the  head  has  come  onto 
the  perineum  or  even  is  visible  during  a  pain.  Either  the  head  is  a  little  too  large, 
or  the  perineum  a  little  too  resistant,  or  the  woman's  nerves  have  given  out.  In 
either  case  labor  has  come  to  a  standstill,  the  pains  weaken,  the  woman  bears  do^^•n 
less  and  less  strongly-,  and,  if  not  relieved,  may  get  into  a  highly  nervous,  even 
delirious  condition,  which  is  not  without  after-effects  on  her  constitution.  The 
child  suffers  too,  the  heart-tones  are  slowed,  then  grow  faster  and  irregular,  and  a 
caput  succedaneum  forms  and  soon  attains  large  dimensions  and  hardness. 

It  is  not  easy  to  select  just  the  right  time  to  interfere  in  these  cases.  Needless 
to  say,  the  conditions  must  all  be  fulfilled.  In  general,  it  is  wise  to  operate  long 
before  the  exhaustion  is  marked,  before  the  signs  and  sjonptoms  of  threatened  rup- 
ture of  the  uterus  are  present,  and  before  the  child  presents  evidences  of  asph^-xia. 
It  is  impossible  to  assign  an  arbitrary  limit,  but  in  my  o^^^l  practice,  when  the 
head  lias  come  well  down  onto  the  perineum  and  makes  no  progress  for  two  and 
one-half  to  three  hours,  I  usually  interfere.  If  the  perineum  seems  to  be  too  resist- 
ant, a  deep  episiotomy  may  allow  the  head  to  go  through — a  procedure  which  is 
much  preferable  to  forceps.  If  episiotomy  does  not  give  exit  to  the  head,  noth- 
ing has  been  lost,  because  the  perineum  would  probably  have  been  incised  for  the 


966  OPERATIVE    OBSTETRICS 

succeeding  delivery  anyway.  I  believe  that  the  forceps  operation,  conil)in('(l  with 
deep  episiotomy,  will  spare  the  child  the  dangers  of  prolonged  cerebral  compres- 
sion, and  thus  prevent  subsequent  cerebral  diseases. 

Arrest  of  the  rotation  of  the  head  is  another  frequent  indication  for  forceps. 
Occipitoposterior  positions  are  most  often  here  concerned,  the  occiput  not  turning 
completely  to  the  front,  but  stopping,  usually  in  the  transverse  diameter  of  the 
pelvis — the  so-called  deep  transverse  arrest.  It  is  not  uncommon  to  find  the  child 
in  the  "military  attitude,"  that  is,  one  of  slight  deflexion,  with  the  head  set  squarely 
on  the  shoulders.  The  sagittal  suture  runs  across  the  pelvis,  the  two  fontanels 
being  about  on  one  level. 

Third  in  frequency  may  be  grouped  a  large  number  of  complications  which 
affect  the  mother,  but  secondarily,  the  child  also,  a  few  of  which  may  be  mentioned. 
Eclampsia,  fever,  or  infection  during  labor,  with  or  without  tympania  uteri ;  acute 
diseases,  as  pneumonia,  typhoid;  chronic  diseases,  tuberculosis,  heart  disease, 
with  the  possibility  of  hemoptysis,  heart  failure,  or  edema  of  the  lungs;  hernia, 
appendicitis,  and  other  intra-abdominal  conditions;  placenta  prsevia,  al^ruptio 
placentae,  prolapse  of  the  cord,  etc. 

Face  and  brow  presentations  per  se  do  not  indicate  forceps  or  any  interference, 
but  the  accoucheur  is  oftener  called  upon  to  intervene. 

Contracted  pelvis  of  itself  is  really  a  contraindication  for  forceps.  Schroder 
says  they  fit  the  contracted  pelvis  like  the  fist  on  one's  eye.  After  the  head  is 
molded  so  that  it  is  almost  ready  to  come  down  into  the  excavation,  and  in  cases  of 
generally  contracted  pelvis,  where  the  powers  give  out  after  the  head  has  engaged, 
it  is  justifiable  to  use  the  forceps  as  an  instrument  of  trial,  but  the  accoucheur  must 
be  constantly  aware  of  their  murderous  possibilities. 

Finally  may  be  mentioned  the  use  of  forceps  on  the  after-coming  head,  a  prac- 
tice which  should,  in  my  opinion,  supersede  many  of  the  difficult  Smellie-Veit 
extractions. 

Conditions  for  Forceps. — These  are  the  same  as  for  extraction  in  general.  (1) 
The  pelvis  must  be  large  enough  to  permit  delivery  of  the  unmutilated  child.  If 
this  point  cannot  be  settled  beforehand,  the  forceps,  if  used,  is  only  an  instrument  of 
trial — of  diagnosis.  Forceps  may  not  be  used  on  a  hydrocephalus,  since  the  blades 
will  usually  slip  off.  If  the  child  is  very  small,  a  diminutive  pair  of  forceps  is  to 
be  employed.  (2)  The  cervix  must  be  effaced  and  dilated,  or  sufficient  enlargement 
must  be  easily  procurable.  Dilatation  of  the  cervix  by  means  of  the  head  pulled 
down  by  forceps  is  a  dangerous — really  unjustifiable — procedure.  (3)  The  mem- 
branes must  be  ruptured  and  out  of  the  way,  because  of  the  danger  of  disloca- 
tion of  the  placenta.  (4)  The  head  must  be  engaged,  or  so  nearly  so  that  a  cautious 
trial  of  the  forceps  may  be  permissible.  (5)  The  child  must  be  living.  If  the  fetus 
is  dead,  craniotomy  should  be  performed;  if  in  doubt,  the  forceps. 

Technic. — We  speak  of  "high,"  "low,"  and  "medium"  forceps,  but  there  is 
no  uniformity  of  teaching  as  to  what  these  terms  mean.  It  would  be  better  to 
designate  the  operation  l)y  the  name  of  the  plane  in  which  the  biparietal  diameter 
is  found,  for  example,  outlet  (for  low),  midplane  (for  medium  or  mid),  when  the 
parietal  bones  lie  in  the  bispinous  line,  and  inlet  forceps  (for  the  term  high),  when  the 
head  lies  in  the  plane  of  the  inlet,  but  has  not  yet  completely  engaged.  To  apply 
the  forceps  on  the  floating  head  is  usuallj'  a  lapsus  art  is. 

A  few  commonly  used  expressions  require  explanation.  The  "front"  of  the 
forceps  is  the  side  of  the  concavity,  the  side  on  which  the  lock  opens,  and  to  which 
the  tips  of  the  blades  point.  The  forceps  may  lie  in  the  pelvis  in  any  of  its  diameters. 
The  forceps  is  said  "to  lie  in  this  or  that  diameter"  when  a  line  drawn  through  the 
centers  of  the  fenestra  lies  in  the  diameter  specified.  The  front  of  the  forceps, 
therefore,  would  look  in  the  diameter  at  right  angles  to  the  one  the  forceps  lies  in. 
The  best  diameter  for  the  forceps  to  take  is  the  transverse,  because  then  their  pelvic 


OPERATIONS    OF   DELIVERY 


967 


curve  corresponds  to  the  mother's  pelvic  curve.  The  child's  head  is  said  "to  lie 
in  this  or  that  diameter"  of  the  pelvis  when  the  sagittal  suture  lies  in  that  diameter. 
"When  the  head  lies  in  the  anteroposterior  diameter  and  the  forceps  lies  in  the  trans- 
verse, the  head  will  l)e  grasped  in  the  most  favorable  manner,  and  the  delivery  of 


Fig.  853. — The  Forceps  Lying  ix  their  Most  Favorable  Position. 
The  head  is  on  the  perineum  and  rotation  is  complete.

the  child  will  be  attended  with  the  least  difficulty  (Fig.  853).  When  the  head  lies 
in  an  oblique  diameter  of  the  pelvis,  the  forceps  should  be  applied  in  the  opposite 
diameter,  the  front  of  the  forceps  pointing  in  the  direction  in  which  the  point  of 
direction  lies  (Fig.  854).     Some  operators  still  place  the  blades  in  the  sides  of  the 


968 


OPERATIVE    OBSTETRICS 


pelvis,  that  is,  in  the  transverse  diameter,  letting  tliem  grasp  the  head  whichever 
way  they  will.  Other  operators  applj'  the  blades  to  the  sides  of  the  head.  When 
the  child's  head  lies  with  its  long  diameter  transversely  in  the  pelvis,  the  only  way 
the  forceps  can  get  a  good  hold  on  it  is  when  they  lie  in  the  anteroposterior  diam- 
eter, but  then  one  blade  Avould  rest  on  the  promontory  while  the  anterior  one  would 
cut  into  the  bladder,  the  curves  of  the  forceps  and  of  pelvis  antagonizing  each  other. 
In  such  cases  a  compromise  must  be  made,  and  the  blades  are  laid  in  one  oblique 
of  the  pelvis  and  grasp  the  child's  head  over  one  malar  bone  and  the  opposite  parietal

There  is  a  strong  tendency  to  slip.     This  application  to  be  avoided  if  possible. 


(Fig.  856).  This  is  Ijettcr  than  to  place  the  blades  one  over  the  face  and  the  other 
over  the  occiput,  the  instrument  lying  in  the  transverse  as  in  Fig.  855.  If  the  head 
is  excessively  flexed,  this  last  is  not  so  objectionable.  The  application  of  the  for- 
ceps to  the  head,  not  to  the  pelvis,  is  the  original  method  taught  by  Levret  and 
Smellie,  and  is  more  scientific,  yet  not  invariably  feasible. 

A  rule  of  the  forceps  operation  to  which  there  are  no  exceptions  is  that  the  front 
of  the  forceps  should  point  in  the  direction  of  the  point  of  direction.  If  the  occiput 
lies  on  the  right  side  of  the  pelvis,  the  front  of  the  forceps  points  to  the  right,  and  as 
the  occiput  rotates  to  the  front,  the  front  of  the  forceps  looks  more  and  more  forward.

tation or  locking;  extraction  of  the  head;  removal  of  the  instrument.  The  prep- 
arations for  the  operation  have  already  been  discussed.  Fig.  857  shows  the  in- 
struments needed.

OPERATIVE    OBSTETRICS 


First  Act — Application  of  Blades  to  Head. — Having  reassured  himself  that  his 
diagnosis  is  correct  by  a  careful  examination  after  the  patient  is  asleep  and  quiet, 
the  accoucheur  seats  himself  on  a  chair  of  convenient  height  and  rehearses  the  in- 
tended operation  in  the  air  before  the  patient.  Two  fingers  of  the  right  hand  are 
passed  into  the  vulva,  vagina,  and,  if  the  cervix  can  he  reached,  inside  the  cervix 
and  within  the  membranes.  Nothing  may  lie  between  the  forceps  antl  the  head, 
and,  to  be  certain  of  this,  the  fingers  must  feel  the  head  all  the  way  and  be  passed 
up  as  high  as  possible,  guarding  the  tip  of  the  forceps  until  it  goes  beyond  reach. 
In  higher  forceps  operations  the  half  hand  should  l^e  inserted.  Now  the  left  blade 
of  the  forceps  is  taken  in  the  left  hand,  poised  vertically  in  the  introitus  vaginae,

being  held  Uke  a  pen  (Fig.  858),  and  passed  with  the  delicacy  of  a  urethral  sound. 
As  the  blade  glides  along  the  fingers  in  the  vagina  the  tip  is  held  closely  to  the  head, 
so  as  to  get  under  the  cord  or  the  membranes  if  they  should  fall  in  the  way.  The 
thumb  of  the  left  hand  is  used  to  guide  and  press  the  blade  into  place.  As  the  fenes- 
trum  disappears  inside  the  vulva,  the  time  is  come  to  sink  the  handle,  and  when  the 
lock  rests  near  the  perineum,  the  first  half  of  this  act  is  completed.  In  most  forceps 
operations,  if  properly  applied,  the  ])lades  will  fall  into  the  right  position  of  their 
OA\Ti  weight.  As  the  handle  sinks  down,  the  operating  hand  glides  over  the  top  and 
now  grasps  it  like  a  scalpel  (Fig.  859).  It  is  not  good  to  hold  the  forceps  like  a 
cathn  in  the  whole  fist. 


OPERATIONS    OF    DELIVERY

The  right  blade  is  passed  in  Hke  manner,  the  two  fingers  of  the  left  hand  being 
inserted  and  acting  as  guide  and  protectors  of  the  maternal  tissues.  The  lock  being 
on  the  top  of  the  left  blade,  this  one  must  be  passed  first,  otherwise  the  handles 
would  have  to  be  recrossed  outside  the  vulva,  after  the  application,  which  would 
subject  the  maternal  tissues  and  the  child  to  injury  by  the  tips  of  the  instrument. 

Second  Act— Adaptation  or  Locking. — The  technic  of  this  movement  will  de- 
pend on  the  presentation  and  position  of  the  head,  since  the  blades  must  be  applied 
so  as  to  fit  it  in  the  best  way. 

In  the  usual  operation  of  forceps  the  head  is  low  down,  and  the  small  fontanel 
has  rotated  all  the  way  or  nearly  all  the  way  to  the  front,  and  the  blades,  after  being 
inserted,  fit  naturally  to  the  sides  of  the  head.  Often,  however,  they  need  a  little 
adjusting  before  it  is  possible  to  fit  the  lock  neatly.  The  simplest  method  to  bring 
the  blades  into  position  is  to  press  the  handles  gently  downward  onto  the  perineum. 
If  this  is  not  successful,  they  are  depressed,  and  at  the  same  time  twisted  lightly 
by  means  of  the  hooks  on  the  handles,  and  if  this  does  not  do,  a  triplex  motion  is 
given  the  instrument.  The  handles  are  pressed  downward,  pushed  upward  into 
the  pelvis,  and  twisted  slightly,  all  in  one  movement,  but  without  the  exhibition  of 
much  force.  If  it  does  not  succeed  easily,  the  forceps  must  be  removed  and  re- 
applied, because  there  is  some  obstacle  to  locking,  which  must  be  recognized  and 
relieved.     To  force  the  locking  is  bad  practice,  and  always  results  in  fetal  or  ma- 


FiG.  859 — Grasping  Forceps  Blade  Like  a  Scalpel.     Second  Motion  of  Insertion. 


ternal  injury.  Usually  the  accoucheur  will  find  he  has  made  an  error  in  diagnosis 
or  that  the  child  has  a  hydrocephalus. 

After  locking,  the  heart-tones  should  be  auscultated.  First  listen  and  note 
their  frequency  and  strength,  then  close  the  blades  and  listen  again.  If  the  tones 
at  once  become  faint  or  slow,  the  cord  is  in  the  grasp  of  the  forceps;  if  the  slowing 
occurs  only  when  the  handles  are  kept  tightly  closed,  it  is  due  to  cerebral  com- 
pression. By  pushing  one  or  two  fingers  up  along  the  back  of  the  child's  neck, 
behind  the  pubis,  it  is  possible  to  feel  the  cord  if  it  encircles  the  neck.  Should  there 
be  a  suspicion  that  the  tip  of  the  forceps  squeezes  the  cord,  the  instrument  must 
be  removed  and  reapplied.  If  compression  of  the  cord  is  unavoidable,  the  delivery 
must  be  quickly  effectedo  An  internal  examination  is  also  made  to  find  if  the  cord 
or  cervix  or  an  arm  is  caught  in  the  grasp  of  the  instrument. 

Third  Act — Extraction. — After  locking  the  forceps  one  gentle  pull  is  made  on 
them  to  see  if  the  blades  lie  properly  and  fit  well,  also  to  give  the  accoucheur  an  idea 
of  the  amount  of  resistance  likely  to  be  met.  This  is  called  the  trial  traction,  and 
after  it  is  made  the  heart-tones  should  again  be  listened  to.  Four  points  must  be 
borne  in  mind  with  each  traction :  (1)  Each  traction  is  made  Avith  the  uterine  pains, 
and  if  these  are  absent,  the  pain  is  imitated,  that  is,  the  pull  is  gradual  at  first,  slowly 
reaches  an  acme,  is  held  for  a  moment,  and  then  slowly  relaxed;  (2)  as  little  power 
is  exhibited  as  possible,  regulating  the  amount  by  the  advance  of  the  head.     With 


972 


OPERATIVE    OBSTETRICS 


the  elbows  at  the  side  and  the  arms  flexed  the  strength  of  the  biceps  alone  should 
suffice,  and  more  than  GO  pounds  will  almost  never  be  required — usually  nmch 
less.  Time  should  be  disregarded,  but  the  fetal  heart-tones  carefully  watched; 
(3)  with  the  single  exception  soon  to  be  considered  the  traction  should  be  simple, 
not  comliined  with  i')cndulum,  corkscrew,  nor  twisting  motions;  (4)  tlie  line  of 
traction  should  correspond  to  the  axis  of  the  parturient  canal. 

After  the  trial  traction  the  forceps  are  grasped,  as  shoA\Ti  in  Fig.  860,  the  right 
hand  over  the  lock,  A\ith  the  little  finger  between  the  shoulders  of  the  shanks  of  the 
l)lades,  the  left  hand  on  the  handles,  both  thumbs  underneath.  One  slow,  even  pull 
is  made,  at  first  in  the  horizontal  plane  or  downward,  or  somewhat  upward,  de- 
pending on  the  station  of  the  head  and  the  curve  of  the  parturient  canal  at  that 
particular  point.     Carefully  note  the  amount  of  progress  of  the  head,  and  allow  the 


FiQ.  800. — Showing  Posture  of  Operator  for  Tkactiox. 


head  to  recede  very  slowly;  then  listen  to  the  heart -tones,  loosening  the  forceps 
after  each  traction.  xVfter  one  or  two  full  minutes  by  a  clock  placed  directly  in 
front  of  the  operator,  another  traction  is  made — if  necessary,  a  little  stronger  than 
the  first.  The  descent  and  rotation  of  the  head  are  determined  by  frequent  ex- 
aminations, the  fingers  searching  for  the  location  of  the  small  fontanel.  As  the 
head  bulges  the  perineum  traction  is  more  upward,  and  the  usual  precautions  to 
save  the  pelvic  floor  are  to  be  observed,  such  as  slow  delivery,  bringing  the  head 
through  with  its  most  favorable  diameters,  and  episiotomy.  In  my  own  practice 
I  seldom  deliver  a  primipara  with  forceps  without  first  doing  an  episiotomy.  This 
saves  the  child's  head  from  prolonged  compression,  shortens  the  time  of  operation, 
forestalls  fetal  a.sphyxia,  and  prevents  a  ragged  laceration,  which  is  almost  in- 
evitable.    If  the  perineum  is  elastic,  it  may  sometimes  be  sufficiently  dilated  with

the  hands.  When  the  head  is  well  engaged  in  the  vulvar  outlet,  the  forceps  may, 
if  preferred,  ])e  removed,  and  tlie  delivery  completed  by  pressurf?  on  the  head  from 
behind  the  anus — Ritgen's  manoeuver.  If  the  operator  is  rigiit  handed,  he  stands 
off  at  the  left  side  of  the  patient,  and  if  he  uses  his  left  hand,  to  her  right  (Fig. 
860).  He  grasps  the  forceps  at  the  lock  with  the  right  (or  left)  hand,  with  the  little 
finger  between  the  shanks,  and  gently,  slowly,  advancing  line  by  line,  he  turns  the 
head  out,  the  handles  of  the  forceps  pointing  toward  the  abdomen.  At  the  same 
time  the  head  is  pulled  up  vertically  somewhat,  to  keep  the  nucha  applied  snugly 
to  the  subpubic  ligament.  From  fifteen  to  thirty  minutes  are  required  for  an  ordi- 
nary forceps  delivery,  most  of  which  time  is  spent  in  bringing  the  head  to  the  peri- 
neum. If  the  operator  wishes  to  deliver  without  episiotomy  and  tries  to  "save  the 
perineum,"  he  must  bring  the  head  through  the  pelvic  floor  very  slowly,  taking  as 
much  time  as  a  natural  delivery  w^ould  take.     INIy  experience  with  this  method  was

not  encouraging,  and  Kerr  found  the  same, — the  children  became  asphyxiated, — 
and  now  I  perform  episiotomy. 

Fourth  Act — Removal. — Some  operators  prefer  to  remove  the  instrument  only 
after  the  head  is  born,  claiming  the  forceps  allows  them  to  prevent  too  rapid  exit 
of  the  head.  Others  remove  them  when  the  head  is  held  tightly  by  the  vulvar  ring, 
claiming  that  the  thickness  of  the  blades  increases  the  tendency  to  perineal  rupture. 
Neither  clami  appeals  to  me,  but  I  usually  deliver  the  head  with  the  forceps.  If 
they  are  removed  sooner,  the  action  is  the  reverse  of  that  of  the  application,  taking 
care  not  to  tear  the  scalp,  the  ear,  or  the  soft  parts  of  the  mother. 

Low  or  Outlet  Forceps. — Here  rotation  is  complete  or  nearly  so,  the  head  is 
most  easily  seized  by  the  instrument,  and  the  blades  lie  on  the  sides  of  the  head, 
over  the  ear.  Applying  the  blades  to  the  sides  of  the  pelvis  allows  them  to  grasp  the 
head  properly.  This  is  the  commonest  forceps  operation,  also  the  least  dangerous. 
The  general  description  just  given  is  all  that  need  be  said  about  it.

FORCEPS  m  THE  UNUSUAL  MECHANISMS  OF  OCCIPITAL  PRESENTATION 

Deep  Transverse  Arrest.-  In  some  cases  where  a  delaj'  in  labor  has  been 
manifest  for  some  time  an  examination  reveals  the  head  well  down  in  the  pelvis, 
the  sagittal  suture  in  the  transverse  diameter,  the  small  fontanel  to  one  side, 
generall}^  the  right,  the  large  fontanel  to  the  other  side,  ancl  both  on  the  same  level. 
This  condition  is  called  "deep  transverse  arrest" — sometimes  "impaction,"  the 
head  being  wedged  in  between  the  ischial  tuberosities.  (See  Deflexion  Attitudes, 
p.  585.)     ^^llen  an  indication  for  the  termination  of  labor  arises  at  a  time  when

rotation  of  the  occiput  is  not  yet  complete,  two  objects  are  to  be  accomplished: 
first,  rotation  must  be  completed;  second,  extraction  is  to  be  made.  Some  Ameri- 
can and  French  operators  turn  the  head  around  in  the  pelvis  with  the  forceps,  and 
twist  the  head  through  an  arc  of  over  135  degrees.  The  author  does  not  recommend 
this  practice.  The  lacerations  of  the  vagina  and  the  avulsion  of  the  bladder  and 
the  vagina  from  their  lK)ny  atta(;hments  are  too  great.  It  is  allowable  to  give  the 
head  the  same  turbinal  or  spiral  movement  it  takes  in  nature,  but  the  accoucheur 
must  be  aware  that  we  are  but  poor  imitators  of  nature,  and  even  with  the  greatest 
care  deep  injuries  are  often  inflicted.     Fig.  862  shows  the  effect  of  twisting  the  for-

rotation  of  the  handles  of  the  forceps  must  be  combined  with  the  pull,  or  traction, 
and  the  two  motions  are  to  be  absolutely  synchronous — never  rotation  without 
progressing  traction. 


976 


OPERATIVE    OBSTETRICS 


It  is  olnious  that  in  transverse  arrest  if  the  forceps  were  applied  to  the  sides  of 
the  head,  the  blades  would  have  to  lie  in  the  conjugate  diameter  of  the  pelvis, 
which  is  mechanically  a  bad  principle,  the  pelvic  curve  of  the  forceps  being  then 
directly  opposed  to  the  curve  of  the  pelvis.  A  straight  forceps  might  thus  be  ap- 
plied were  there  not  other  objections,  for  example,  injury  to  the  bladder  by  the 
anterior  blade.  If  the  instrument  were  laid  transversely,  it  would  seize  the  head 
over  the  face  and  occiput  (Fig.  855),  injuring  the  eyes,  deflexing  the  head,  and  in- 
viting a  tendency  to  slipping.     It  is  best  to  grasp  the  head  obliquely  (Fig.  864),

one  blade  lying  on  the  parietal  bone,  the  other,  on  the  malar.  The  forceps,  there- 
fore, will  lie  in  an  oblique  diameter  of  the  pelvis.  In  O.D.Transverse,  the  forceps 
will  lie  in  the  right  obliciue,  in  O.L.Transverse,  in  the  left. 

Operation  in  Transverse  Arrest  in  O.D.P.— Since  the  front  of  the  forceps 
must  point  in  the  direction  of  the  point  of  direction,  in  this  case  the  occiput,  the 
blades  must  be  brought  to  lie  in  the  right  oblique  diameter  of  the  pelvis,  one  an- 
teriorly behind  the  iliopubic  tubercle,  lying  over  the  anterior  malar  bone,  the  other 
posteriorly,  opposite   the   right  sacro-iliac  joint,  lying   on   the    posterior  parietal 


OPERATIONS    OF   DELIVERY 


977 


bone.  The  left  blade,  therefore,  has  to  be  guided  around  the  side  of  the  pelvis 
over  the  child's  face,  to  come  into  position,  (Figs.  866  and  867),  while  the  right  blade 
does  not  have  to  "wander"  at  all,  but  may  be  laid  directly  opposite  the  sacro-iliac 
joint.  While  the  hlade  is  being  pushed  in  b}^  the  outside  hand,  the  fingers  inside 
pull  it  around  the  pelvis.  Locking  is  not  easy  in  these  cases,  ])ut  is  done  as  before 
described,  and  the  operator,  knowing  that  the  head  is  grasped  in  one  of  its  long 
diameters,  will  not  bring  the  handles  too  close  together.  A  good  way  for  the 
accoucheur  to  assure  himself  that  the  child's  head  does  not  suffer  injurious  pressure 
is  for  him  to  put  the  index-finger  of  his  left  hand  between  the  handles  while  making 
traction.  Extraction  is  accompanied  by  slight  and  gentle  rotation,  the  two  move- 
ments being  absolutely  s.ynchronous,  producing  a  turbinal  or  spiral  rotation  (Fig. 
868).  The  front  of  the  forceps  points  to  the  right,  and  the  turbinal  movement 
imparted  to  the  instrument  is  from  right  to  left  and  from  above  downward,  opposite 


Fig.  867. — Showing  how  to  Turn  Forceps  Blade. 


that  shown  in  Fig,  868,  which  is  for  O.L.T.  At  the  same  time  the  force  applied  is 
so  directed  that  the  tractive  impulse  is  first  felt  on  the  parietal  bone  l3'ing  pos- 
teriorly. It  is  difficult  to  describe  this  delicate  operation,  because  this  is  the  art 
of  the  accoucheur,  and  is  attainable  only  by  practice.  The  first  traction  should  be 
simply  downward,  to  see  if  rotation  will  not  take  place  inside  the  forceps,  which 
not  seldom  occurs.  If  there  is  no  tendency  for  this,  the  second  traction  is  combined 
with  rotation,  from  right  to  left,  so  as  to  bring  the  occiput  around  to  the  front. 
After  a  little  rotation  has  taken  place,  which  is  discovered  by  frequent  examinations, 
the  small  fontanel  l^eing  the  landmark,  the  blades  are  opened  and  allowed  to  rest 
at  the  sides  of  the  head.  A  few  pains  may  complete  the  process.  As  rotation 
occurs  the  blades  are  readapted  so  as  to  lie  more  and  more  on  the  sides  of  the  head, 
and  as  the  instrument  grasps  the  head  in  more  favorable  diameters,  the  handles 
come  closer  and  closer  together.  If  the  fetal  heart-tones  are  good,  time  may  be

disregarded.  After  rotation  is  complete  the  forceps  may  ])e  removed  and  the  case 
left  to  nature.  This  is  often  desirable  in  primiparse  with  rigid  parts  and  large  babies. 
If  the  pains  are  strong,  the  head  is  properly  molded  within  a  few  hours,  and  the 
subsequent  low  forceps  operation,  if  it  Ijecomes  necessary,  is  much  easier.  Many 
object  to  this  "two-stage"  forceps  operation,  as  subjecting  the  parturient  to  two 
anesthesias,  and  because,  when  she  awakens,  she  is  disappointed  not  to  have  been 
delivered,  also  on  the  score  of  the  consumption  of  time  and  the  increase  of  trouble

This  is  as  applied  to  a  head  in  O.L.T. 


on  the  part  of  the  accoucheur  and  nurses,  but  extensive  experience  has  convinced 
me  that  the  benefits  resulting — absence  of  lacerations,  avoidance  of  fetal  injury  and 
asphj^xia,  and  ease  of  subsequent  operation — often  offset  the  disadvantages.  Nat- 
urally, one  may  wait  only  when  there  is  no  indication  for  the  immediate  termination 
of  labor. 

If  the  delivery  must  be  completed  at  once  after  the  small  fontanel  comes  to 
the  front,  the  rest  of  the  operation  is  the  same  as  was  described  under  Low  Forceps.

Forceps  in  Occipitoposterior  Positions. — The  reader  is  referred  to  p.  584  for 
details  of  treatment  of  occipitoposterior  positions.  Since  the  forceps  operation 
may  be  considered  at  all,  it  means  that  the  head  has  engaged,  and  that,  in  spite  of 
strong  pains,  or  eventually  in  spite  of  the  procedm-es  of  rectification  before  men- 
tioned, the  occiput  remains  persistently  posterior.  I  have  very  seldom  found  it 
necessary  to  apply  the  forceps  to  an  occipitoposterior  as  such,  and  these  cases  were 
almost  always  those  where  the  head  was  fast  on  the  pelvic  floor,  the  small  fontanel 
pointing  to  the  sacrum,  and  the  time  for  manual  correction  past.  Under  such 
circumstances  the  occiput  must  be  delivered  over  the  perineum,  and,  as  will  be 
seen  if  reference  is  made  to  the  chapter  devoted  to  the  Mechanism  of  Occipito- 
posteriors,  it  is  best  to  deliver  the  head  in  extreme  flexion.  Some  operators  use 
for  this  purpose  straight  forceps  without  pelvic  curve,  since  they  allow  a  better 
grasp  over  the  parietal  bosses,  but  mj'  experience  shows  that  the  advantage  is  not 
great  enough  to  induce  one  to  have  a  pair. 

The  application  of  the  blades  is  made  as  usual,  but  the  front  of  the  forceps 
looks  toward  the  forehead,  which,  from  now  on,  becomes  the  point  of  direction 
(Fig.  869).     Locking  the  blades  is  the  same  as  usual,  but  after  they  are  locked  the 


Fig.  869. — Forceps  is  Occiput  Posterior  Position  on  Pelvic  Floor. 


handles  are  raised  a  little  toward  the  pubis — this  to  increase  flexion.  Traction  is 
made  on  the  parietal  bosses,  a  little  upward  from  the  horizontal  plane.  This  in- 
creases flexion,  and  it  has  happened,  though  I  have  never  observed  it,  that  even 
as  late  as  this  anterior  rotation  has  occurred.  The  occiput  is  first  delivered  over 
the  perineum,  the  forehead  resting  behind  the  pubis;  then  the  brow  and  face  come 
from  under  the  pubis.  Much  power  is  often  necessary,  and  it  is  advisable  to  per- 
form episiotomy  in  primiparse,  as  a  rule,  and  almost  always  in  multiparse.  to  avoid 
extensive  lacerations  of  the  pelvic  floor  and  sphincter. 

When  it  becomes  necessary-  to  appl}'  forceps  with  the  occiput  in  a  position 
between  the  transverse  diameter  and  the  hollow  of  the  sacrum,  great  difficulties  are 
met,  and  the  operation  should  not  be  lightly  undertaken.  I  am  convinced  that  ten 
times  the  number  of  babies  are  lost  from  this  complication  in  the  United  States 
than  from  contracted  pelvis.  It  is  often  possible,  by  combined  manipulation,  to 
rotate  the  head  into  the  anterior  quadrant  of  the  pelvis,  or  at  least  into  the  trans- 
verse, and  hold  it  there  until  the  forceps  can  be  applied,  which  very  much  simpHfies 
the  operation.  If  this  is  impossible,  the  forceps  are  applied  in  the  transverse  di- 
ameter of  the  pelvis,  and  traction  made  in  the  horizontal  plane,  no  attempt  at  rota- 
tion being  practised,  the  object  being  to  observe  and  discover  the  mechanism  in-

tended  by  nature.  If  the  occiput  comes  down,  flexion  is  increased  and  some  anterior 
rotation  occurs.  If  it  is  noticed  that  nature  intends  this  mechanism,  the  forceps 
are  opened  and  reapphed  in  a  manner  to  favor  the  indicated  mechanism,  the  process 
being  repeated  at  intervals  as  the  small  fontanel  turns  toward  the  pubis.  If,  on 
the  contrary',  the  occiput  should  show  a  tendency  to  rotate  posteriorly,  no  attempt 
should  be  made  to  hinder  this.  To  force  the  rotation  into  an  anterior  position 
would  seldom  succeed,  and  there  is  great  danger  of  tearing  the  soft  parts.  The 
accoucheur  should  be  guided  b}'  what  he  finds  nature  is  intending  to  do,  and  should 
aid  that  mechanism.  It  may  be  necessary  to  remove  and  reapply  the  forceps  three 
or  four  times  to  accommodate  the  dilTerent  positions  which  the  head  takes  in  pas- 
sage. Some  accoucheurs  prefer  the  axis-traction  forceps  for  these  cases  on  this 
account,  but  for  the  man  who  knows  the  mechanism  of  labor  and  is  willing  to  be 
guided  by  the  action  of  the  natural  powers  they  are  unnecessary,  and  in  the  hands 
of  a  man  ignorant  of  the  principles  of  the  science  of  obstetrics  the  instrument  is 
too  dangerous.

forceps  delivery,  but  in  a  not  small  experience  I  have  used  it  only  twice,  and  then 
merely  to  try  it.  It  is  entirely  dispensable,  and,  in  my  opinion,  is  fraught  with  too 
great  dangers  to  the  maternal  soft  parts  to  be  practised  by  any  but  experts.  The 
forceps  are  applied  with  the  front  looking  toward  the  forehead.  By  rotating  the 
instrument  the  forehead  is  brought  to  the  rear,  which,  of  course,  inverts  the  forceps. 
They  are  removed  and  reapplied,  with  the  front  toward  the  occiput,  which  has  come 
to  the  pubis,  and  the  operation  is  completed  as  usual  after  rotation  has  occurred. 
Jaggard  taught  that  it  is  too  dangerous  to  rotate  the  head  through  an  arc  exceeding 
one-fourth  of  a  circle,  and  my  experience  convinces  me  that  he  was  right. 

Forceps  in  Face  Presentations. — Per  se  face  presentation  is  no  indication  for 
forcejis,  but  labor  is  often  delayed  and  help  often  required  with  all  the  deflexion 
attitudes.  In  face  presentation,  to  the  conditions  demanded  for  forceps  in  general 
one  new  one  must  be  added — the  chin  may  not  be  behind  the  transverse  diameter 
of  the  pelvis — that  is,  anterior  rotation  of  the  chin,  at  least  to  tlie  transverse  di- 
ameter, must  have  occurred.  The  forceps  operation  otherwise  is  usually  equiva- 
lent to  a  craniotomy. 


OPERATIONS    OF    DELIVERY 


981 


Application  of  the  blades  after  the  chin  has  rotated  is  very  easy,  although  care  is 
required  not  to  injure  the  baby's  eyes.  Adaptation  or  locking  is  different.  In- 
stead of  depressing  the  handles,  it  is  best  to  raise  them  well.  This  sinks  the  blades 
toward  the  hollow  of  the  sacrum,  and  thus  they  obtain  a  firmer  hold  over  the  parietal 
bosses.  Straight  forceps  should  be  useful  here.  If  the  blades  are  placed  and  locked 
in  the  usual  manner,  they  will  slip  off  the  narrow  brow  and  face — they  are,  there- 
fore, locked  with  the  handles  raised,  and  then  the  latter  are  lowered,  which  man- 
oeuver  increases  extension  (Fig.  870).  Traction  is  first  dowTiward,  to  increase 
deflexion,  then  in  the  horizontal  plane,  until  the  chin  is  well  out  from  under  the 
pubis,  then  upward,  but  not  so  acutely  as  with  the  occiput,  because  the  delicate 
larj-nx  is  between  the  spine  of  the  child  and  the  bone.  Episiotomy  is  the  rule  in 
primiparae.

The  largest  circumference  of  the  head  is  about  to  pass  the  inlet.     The  lowest  part  of  the  head  lies  in  the  interspinous 

line.     Owing  to  the  perspective,  it  seems  as  if  it  were  below  this  line. 


chin  is  directed  toward  the  hollow  of  the  sacrum  is  possible  only  when  the  child  is 
small,  and  then  onlj'  at  the  expense  of  extensive  lacerations.  •  To  try  to  rotate  the 
chin  anteriorly  by  means  of  forceps  from  a  posterior  quadrant  of  the  pelvis  is 
equivalent  to  a  craniotomy,  and  much  more  damaging  to  the  mother's  tissues.  It 
is,  however,  possible  safely  to  deliver  a  face  presentation  arrested  in  rotation  after 
the  chin  has  reached  or  passed  the  transverse  diameter,  but  the  operation  is  very 
delicate,  very  difficult,  usually  causes  deep  tears,  and  often  costs  the  child's  life. 
The  reason  for  the  last  is  obvious.  One  blade  compresses  the  neck  and  always 
injures  the  structures  exposed  by  the  extreme  extension  of  the  cervical  spine.  The 
forceps  lie  in  an  oblique,  the  front  pointing  in  the  direction  of  the  point  of  direction. 
In  M.D.T.  the  forceps  lie  in  the  right,  in  ^I.L.T.  in  the  left,  oblique.  Extraction 
must  be  most  carefully  done,  loosening  the  forceps  frequenth'  and  readapting  them

at  the  earliest  possible  moment  to  the  sides  of  the  head.  Rotation  is  effected  by 
giving  the  forceps  a  slight  turbinal  movement,  but  much  may  also  be  accomplished 
by  manipulation  with  the  fingers.

Forceps  in  Brow  Presentation. — What  was  said  under  Face  Presentation  ap- 
plies here.  The  brow,  instead  of  the  chin,  must  come  to  the  pubis  and  appear  in  the 
vulva,  the  face  resting  behind  the  symphysis  until  the  occiput  can  be  l)rought  over 


OPERATIONS    OF    DELIVERY

the  perineum,  after  which  the  face  comes  down  from  behind  the  pubis.     Episiotomy 
is  the  rule  in  primiparse  and  in  multiparae,  too,  if  the  child  is  large. 

Inlet  Forceps  Operations — "High  Forceps." — In  most  of  the  cases  of  forceps 
just  descril)ecl  the  head  occupies  the  excavation  of  the  pelvis,  and  we  might  speak 
of  "midplane  forceps,"  as  was  already  mentioned.  The  term  "high  forceps"  is 
best  limited  to  those  cases  where  the  biparietal  diameter  is  in  the  region  of  the  su- 
perior strait,  but  has  not  yet  passed  lower,  or  has  not  even  as  yet  entered  the  inlet, 
but  is  arrested  just  above  it.  Some  operators  permit  the  use  of  forceps  on  the 
"floating  head."     I  have  not  found  this  necessary,  having  been  able  to  do  a  version,

or  at  least  to  force  the  head  down  into  the  pelvis,  by  means  of  outside  pressure,  so 
that  it  could  be  easily  grasped.  In  some  cases  (Fig.  871)  the  head  is  so  well  fixed 
that  it  may  be  impossible  to  move  it  away  to  do  version,  and  yet  it  is  not  quite 
engaged  so  as  to  fulfil  the  condition  for  forceps.  Under  these  circumstances  the 
forceps  is  an  instrument  of  trial,  or,  as  Carl  Braun  said,  "an  instrument  of  diag- 
nosis." We  want  to  see  if  the  head  will  come  into  the  pelvis.  If,  after  suitable 
trial,  the  head  will  not  come  in,  we  must  do  a  craniotomy,  even  if  the  child  be  alive, 
or,  if  both  patients  are  in  prime  condition,  perform  hebosteotomy. 

For  deliveries  begun  when  the  head  is  above  the  level  of  the  spines  of  the  ischia 
many  authors  recommend  a  special  instrument,— the  axis-traction  forceps,— that 


984 


OPERATIVE    OBSTETRICS 


is,  an  instrument  ^vhieh  will  enal)le  us  to  apply  force  to  the  head  parallel  to  the  axis 
of  the  pelvis. 

The  head,  when  high  up,  has  a  curve  to  traverse.  Owing  to  the  forward  pro- 
jection of  the  sacrum  and  iierineum,  traction  cannot  be  applied  in  the  axis  of  the 
inlet.  If  applied  in  any  other  line,  the  problem  is  like  trying  to  jouU  an  object 
around  a  corner — both  the  corner  and  the  object  suffer. 

Fig.  872  shows  the  effect  of  the  ordinary  forceps  when  applied  on  the  liigli  liead;  if  traction 
is  made  in  the  usual  wa^^,  a  hirge  part,  estimated  by  Tarnier  as  almost  half,  of  tlie  force  will  be 
exerted  against  the  symphysis.  The  older  obstetricians  appreciated  tlie  fact  that  the  head  would 
thus  impinge  on  the  anterior  pelvic  wall,  and  Saxtorph  (1780)  recommended  that  tapes  be  put 
through  the  fenestra  of  the  forceps,  and,  while  pulling  in  the  usual  manner,  also  to  pull  downward 
on  the  tapes,  thus  making  the  head  follow  the  curve  of  the  parturient  canal.     Osiander  (1800) 


Fig.  870. — Tarnier  Axisttr.^ction  Forceps.     Last  Model. 


advised  to  pull  downward  toward  the  floor  with  one  hand  over  the  lock,  while  the  other  pulled 
the  forceps  straight  out — a  manoeuver  which  is  generally  known  as  Pajot's  (Fig.  874).  In  1844 
Hermann,  of  Berne,  instead  of  the  tapes,  attached  a  straight  hook  to  the  blade  near  the  head,  and 
the  Huberts,  in  1860,  bent  the  handles  down  so  that  when  traction  was  made  on  the  lowest  parts 
the  force  was  transmitted  through  the  bent  lever  to  the  head  in  the  axis  of  the  inlet.  Finally,  in 
1877,  Tarnier  invented  a  forceps  which  he  believed  possessed  these  advantages — (1)  It  allowed 
traction  to  l)e  made  in  the  axis  of  the  inlet;  (2)  while  the  head  was  fixed  in  the  forceps  proper  the 
traction  apparatus  was  so  joint(>d  that  the  head  was  given  fr(>e  mobility  and  could  follow  the 
impulses  of  the  mechanism  of  laI)or;  (3)  the  handlers  of  the  forceps  could  be  used  as  indicators 
of  the  lines  the  head  was  following.  Tarnier  constructed  over  100  models  before  he  considered 
the  instrument  perfect  (Fig.  876).  Simpson,  Murray,  Lusk,  Breus,  Felsenreich,  and  many 
others  sought  to  improve  on  Tarnier's  instrument,  but  of  all  axis-traction  instruments,  in  my 
opinion  those  of  Tarnier  and  Simpson  are  the  best. 

Axis-traction  forceps  are  not  universally  recommended  by  obstetric  aut  horit  ies.  In  England, 
Kerr,  Milne-Murray,  Eden,  and  others  recommend  them;  in  Germany,  opinion  is  nearly  evenly 
divided,  the  balance  l)eing  slightly  in  their  favor;  in  France,  Pajol,  Dcpaul,  and  others  oppos(>d 
Tarnier,  but  the  large  majority  was  with  him;  in  America,  nearly  all  writers  are  in  favor  of  them. 
Vienna  is  lukewarm,  and  Bossi,  in  Genoa,  says  they  are  entirely  dispensable.  For  my  part  I 
cannot  share  the  enthusiasm  of  Williams,  Kerr,  Murray,  and  others.  By  means  of  the  Osiander 
manoeuver  I  can  give  the  head  a  direction  which  a  knowledge^bf  the  mechanism  of  labor  will 


OPERATIONS    OF    DELIVERY 


985 


indicate;  by  careful  observance  of  the  tendencies  of  movement  which  the  forces  of  nature  give  the 
head  I  can  determine  in  wliich  way  to  apply  traction,  and  I  can  aid  one  or  the  other,  as  required. 
With  the  axis-traction  device  there  are  so  many  joints  between  the  operating  hand  and  the  head 
that  it  is  impossible  to  impress  on  the  latter  any  specific  motion.  All  the  knowledge  one  ha.s 
accumulated  regarding  normal  and  abnormal  labor  mechanisms  goes  for  naught,  and  all  one 
can  do  is  to  pull  hlindlj'  on  the  cross-bar.  In  this  respect  the  axis-traction  forceps  are  not  artistic. 
In  actual  practice,  where  I  have  applied  both  instruments  on  the  same  case,  I  have  been  better 
satisfied  with  the  simple  Simpson  forceps  and  seldom  use  any  other.  Deep  injuries  to  the  maternal 
tissues  are  just  as  frecjuent  with  the  new  forceps,  a  fact  w'hich  \\.  A.  Frcund  proved.  The  Tarnier 
instrument  has  a  murderous  cephalic  curve,  cognizance  of  which  should  be  taken  when  screwing 
together  the  handles,  otherwise  a  large  number  of  tlead  and  injured  children  will  be  the  result. 
In  all  a.xis-traction  instrvunents  there  is  the  possibility  of  the  curved  arms  or  the  joints  bending 
or  breaking  under  the  powerful  force  applied,  having  witnessed  three  such  accidents  myself. 


Fig.  877. — Axis-traction  Forceps  Applied  at  the  Inlet. 


Indications  for  High  Forceps. — These  are  the  same  as  usual — danger  to  the 
mother  or  child,  occurring  at  a  time  when  the  head  has  not  yet  passed  through  the 
inlet.  Let  it  be  well  emphasized  that  the  indication  for  forceps  here  must  be 
unusually  strict. 

Conditions.— These  also  are  as  usual,  and  to  be  strictly  insisted  on.  Engage- 
ment of  the  head  must  be  so  nearly  accomplished  that  the  accoucheur  feels  certain 
that  a  little  pull  from  below  will  help  the  head  into  the  pelvis.  He  must  remember 
the  alternative  if  he  fails — craniotomy  or  hebosteotomy.  The  pelvis  may  not  be 
too  contracted— not  less,  than  8}^  cm.  in  flat  and  9  cm.  in  the  justominor  tj-pes. 
Dilatation  of  the  cervix  and  retraction  of  the  pelvic  organs  above  the  inlet  must 
be  positively  complete. 


986  OPERATIVE    OBSTETRICS 

The  operation  itself  is  quite  a  little  more  complicated  than  the  low  or  midplane 
forceps,  but  the  principles  are  identical.  In  applying  the  blades  the  half  or  even 
the  whole  hand  should  be  inserted  as  a  guide.  Adaptation  of  the  blades  must  be 
to  the  sides  of  the  pelvis,  because  the  instrument,  being  pushed  in  so  far,  must  have 
its  pelvic  curve  correspond  to  that  of  the  pelvis.  The  head,  therefore,  will  be 
grasped  in  the  sagittal  diameter,  especially  in  flat  pelves,  where  the  head  enters  in 
the  transverse  diameter,  and  one  blade  will  lie  over  the  occiput,  the  other  over  the 
face  (Fig.  877).  To  prevent  serious  injury  of  the  child  the  handles  may  not  be 
tightly  screwed  together.  In  using  the  ordinary  forceps  a  finger  is  laid  between  the 
handles.  Locking  is  more  difficult  and  is  done  as  usual.  No  force  may  be  employed, 
and  the  hand  outside  may  help  adjust  the  forceps,  the  tops  of  whose  blades  may  thus 
be  manipulated  above  the  pubis.  Before  articulating  the  blades  it  may  be  necessary 
to  adjust  the  head  to  the  pelvis  by  combined  manipulation.  In  extracting,  it  is 
to  be  remembered  that  the  high  forceps  is  an  operation  of  trial — of  diagnosis. 
Traction  should  be  made,  accortUng  to  Tarnier,  in  the  direction  indicated  by  the 
handles,  the  traction  rods  lying  1  cm.  away  from  the  shanks  (Fig.  877).  If  six,  or 
at  most  eight,  powerful,  well-directed  tractions  make  no  impression, — do  not  bring 
the  head  lower, — the  instrument  must  be  removed.  Two  or  three  of  the  tractions 
should  be  made  with  the  patient  in  the  Walcher  position.  Craniotomy  now  must 
be  done,  or  if  the  mother  and  babe  are  in  prime  condition  and  the  environment  is 
favorable,  hebosteotomy.  If  the  head  does  move  a  little  with  each  traction,  the 
operation  should  be  gently  completed,  taking  plenty  of  time.  After  the  head  has 
entered  the  pelvis  it  may  rotate  within  the  forceps,  which  should  be  opened  to  per- 
mit this,  or  it  may  be  turned  by  combined  manipulation,  the  case  now  being  simply 
one  of  arrest  at  the  midplane.  It  may  be  desirable  to  remove  the  axis-traction 
apparatus  and  deliver  as  in  ordinary  forceps,  or  it  may  be  best  to  leave  the  delivery 
to  nature,  or  to  follow  a  subsequent  indication. 

Prognosis  of  the  Forceps  Operation. — For  the  mother,  the  dangers  are  injury, 
hemorrhage,  and  infection.  Some  tearing  of  the  pelvic  organs  is  inevitable,  and  the 
number  and  severity  increase  the  higher  up  the  forceps  operation  is  done.  High 
forceps  show  the  most  and  the  worst  injuries,  which  may  be  atrocious  if  the  condi- 
tion relating  to  the  dilatation  had  not  been  fulfilled.  If  rotary  motions  with  the 
forceps  are  made,  the  vagina  may  be  twisted  from  its  connective-tissue  attach- 
ments, or  the  cervix  may  be  caught  in  the  grasp  of  the  forceps  and  be  bruised  or 
torn  off  bodily;  or  the  operator,  thinking  the  blade  is  inside  the  cervix,  may  use 
force,  and  as  the  tip  of  the  instrument  is  in  the  fornix,  he  may  punch  through  this 
up,  under,  or  through  the  peritoneum. 

The  vagina  itself  may  be  torn  or  cut  by  the  blades  of  the  forceps  and  the  vulva 
also,  especially  when  the  blades  are  l^ent  upward  in  the  delivery  of  the  head.  The 
edges  may  cut  the  crura  of  the  clitoris  and  cause  severe  hemorrhage,  or  pressure 
necrosis  which  may  go  to  the  bone.  In  severe  forceps  operations  the  symphysis 
pubis  has  been  ruptured,  also  the  sacro-iliac  articulations,  and  the  woman  will 
have  a  pain  in  the  lower  spine  and  back,  with  more  or  less  invalidism  all  the  rest 
of  her  life.  Injury  to  the  sacro-iliac  joints  is  a  frequently  overlooked  cause  of  back- 
ache, leukorrhea,  and  many  gynecologic  conditions.  The  bladder  may  be  torn 
into,  or  may  be  pulled  off  its  pelvic  attachments  and  be  permanently  prolapsed. 
Scars  in  the  vaginal  wall  may  distort  the  bladder  sphincter,  causing  incontinence 
and  cystitis.  Injury  to  the  levator  ani  and  pelvic  floor  is  a  constant  sequel  to  forceps 
delivery.  At  autopsy  one  is  astonished  at  the  extent  and  number  of  the  tears  and 
bruises.  Postpartum  hemorrhage  results  from  the  tears  and  from  atonia  uteri. 
Infection  is  common  from  lapses  of  asepsis  and  from  the  ease  with  which  contused 
wounds  are  successfully  attacked  ])y  the  bacteria. 

Most  dangerous  to  both  mother  and  child  is  the  slipping  of  the  forceps.  This 
happens  in  two  ways,  according  to  Mme.  La  Chapelle:   in  the  vertical  sense,  that 


OPERATIONS    OF   DELIVERY 


987 


is,  the  forceps  slide  off  in  the  direction  of  the  hne  of  traction;  and  in  the  horizontal 
sense,  that  is,  the  forceps  slip  off"  in  a  line  perpendicular  to  the  line  of  traction, 
the  patient  being  imagined  erect  (Figs.  878  and  879).  I  believe  the  terms  "axial" 
and  "exaxial"  slipping  would  more  clearly  express  the  conditions. 

The  causes  of  slipping  of  the  forceps  are:  Grasping  the  head  too  low,  the  forceps 
not  being  inserted  high  enough,  under  a  mistaken  idea  of  the  degree  of  engagement ; 
the  blades  feather  too  much — a  poor  instrument;  the  head  may  be  too  small  or 
too  large — hydrocephalus;  the  head  is  not  grasped  right;  the  handles  are  bent  up 
too  soon  as  the  head  nears  the  outlet. 

The  sensation  of  slipping  of  the  forceps  is  unmistakable.  The  handles  tend 
to  separate,  and  if  the  direction  is  to  the  front  or  back  of  the  pelvis,  the  blades  seem 
to  jump  off  the  head  with  a  snapping  noise,  and  they  are  usually  disarticulated. 
If  the  forceps  slip  off  in  the  line  of  traction,  i.  e.,  axially,  one  can  feel  the  instrument 


Fig.  878. — Slipping  of  Forceps.     Horizontal  Sense.     Exaxial. 


advance  while  the  head  seems  not  to  follow.  Slipping  of  the  forceps  is  commonest 
at  the  inlet,  because  here  the  walls  of  the  pelvis  do  not  hold  the  blades  to  the  sides 
of  the  head.  It  is  highly  essential  to  discover  the  tendency  to  slip  early,  because  the 
lacerations  caused  by  it  are  frightful.  Removal  of  the  blades  and  reapplication 
are  the  treatment.  If  the  head  is  small,  a  small  forceps  must  be  secured.  If  there 
is  a  hydrocephalus,  puncture  is  required.

asphyxia.  (2)  Fracture  of  the  skull,  with  or  without  subdural  hemorrhage.  (3) 
Hemorrhage  from  rupture  of  the  sinuses  at  the  base  or  from  rupture  of  the  tentorium 
cerebelli.  (4)  Concussion  of  the  brain.  (5)  Crushing  of  the  orbital  plates,  with 
retrobulbar  hematoma  and  injury  to  nerves  and  muscles,  causing  squint,  ptosis, 
etc.  (6)  Injury  to  the  eyes,  traumatic  cataract,  abruption  of  the  choroid,  corneal 
opacity,  retinal  hemorrhage,  enucleation  of  the  eye.     (7)  Facial  paralysis,  from  com-

pression  of  the  nerve  as  it  comes  out  in  front  of  the  mastoid.  Usually  good  prognosis. 
(8)  Pressure  necrosis  of  the  scalp,  perhaps  to  the  bone.  (9)  It  is  said  that  idiocy 
is  more  frequent  after  forceps.  (10)  Cephalhematoma — usually  good  prognosis. 
(11)  Compression  or  cutting  of  the  umbilical  cord,  with  asphj-xia.  (12)  It  is 
possible  that  deafness  may  be  due  to  injury  or  hemorrhage  into  the  organs  of  hear- 
ing, etc.  (13)  Indeed,  nearly  every  imaginable  injury  has  been  observed  and  in 
general,  forceps  babies  are  more  liable  to  infection,  pneumonia,  atelectasis,  menin- 
gitis, hemophilia,  etc. 

Dystocia  Due  to  the  Shoulders. — If,  after  delivery  of  the  head,  the  shoulders 
do  not  immediately  follow  gentle  traction,  applied  as  indicated  under  the  conduct 
of  normal  labor,  the  accoucheur  should  make  an  examination  with  four  fingers  to 
determine  the  cause  of  delay.  One  or  the  other  of  the  following  conditions  will  be 
found:    (1)   The  shoulders  are  broad  and  firm;    (2)  they  have  followed  an  unfavor-

able  mechanism,  the  anterior  shoulder  being  caught  on  the  ramus  pubis,  or  having 
over-rotated,  and,  the  accoucheur  not  observing  this,  he  tries  to  bring  the  shoulder- 
girdle  down  in  the  wrong  diameter;  (3)  the  cord  is  too  short;  (4)  the  chest  of  the 
child  is  too  large  (anasarca) ;   (5)  locked  twins  or  a  monster  exists. 

The  head  springs  backward  against  the  perineum,  pressing  this  well  up  into 
the  pelvis,  and  traction  serves  only  to  stretch  the  neck.  Not  a  few  children  have 
been  lost  at  this  stage  of  delivery. 

Treatment. — If  the  woman  is  conscious,  she  should  be  exhorted  to  bear  down 
strongly,  failing  which  the  assistant  makes  a  strong  Kristeller  expression.  Now, 
by  means  of  the  fingers  inside  and  the  hand  outside,  the  shoulder-girdle  is  rotated 
into  the  most  favorable  pelvic  diameter — one  of  the  obliques.  Next,  the  accoucheur 
inserts  four  fingers  of  the  left  hand  into  the  vagina  in  search  of  the  posterior  axilla, 
into  which  he  puts  his  index,  and,  pulling  gently,  he  tries  to  bring  the  posterior 
shoulder  down  into  the  hollow  of  the  sacrum.     This  may  be  aided  by  crowding  the

terior shou  der  has  been  brought  to  the  perineum  the  han.l  is  withdrawn  and  the 
child  s  head  allowed  to  drop-<.ven  a  little  gentle  traction  may  be  made  downward 
to  bring  the  anterior  shoul.ler  under  the  pubic  arch.  If  this  fails,  which  is  rare  a 
trial  IS  made  to  bring  the  anterior  shoulder  under  the  pubis  bv  downward  traction 
on  the  head,  combined  with  pressure  from  above  the  pubis.  E.xce.ssivc  caution  is 
here  required  because  only  too  easily  is  the  clavicle  fractured  or  the  cervical  plexus 
torn  or  pulled  out  of  the  spinal  cord.

Failing  these  plans,  next  to  do  is  to  deliver  the  posterior  arm,  it  being  necessary 
to  insert  the  whole  hand  in  order  to  reach  it,  and  it  is  wiped  down  ovi-r  the  face — 
not  over  the  back.  Now  extraction  is  always  possible  unless  there  is  some  mon- 
strosity. This  will  at  once  be  discovered  by  the  hand,  which  has  l>een  introduced, 
and,  of  course,  the  treatment  will  V)e  guided  by  what  is  found.  Exenteration,

CHAPTER  LXXII 

CESAREAN  SECTION 

Cesarean  section  is  the  removal  of  the  child  from  the  uterus  through  an  in-' 
cision  made  in  the  abdominal  wall.     The  term  may  not  be  applied  to  the  removal  of 
the  child  from  the  belly  after  rupture  of  the  uterus,  nor  to  operations  for  ectopic 
pregnancy. 

The  term  probably  is  derived  from  the  Latin,  partus  ccsnreus,  from  cedere,  to  cut.  The 
term  cesarean  section,  therefore,  is  really  a  redundancy.  There  is  no  evidence  to  show  that 
Julius  Caesar  was  thus  delivered.  Cesones  (children  delivered  by  section  from  their  dead  mothers) 
were  known  long  before  Caesar's  time,  and  the  operation  was  not  performed  on  the  living.  Caesar's 
mother  was  alive  at  the  time  of  his  wars,  as  is  proved  by  liis  letters  to  her. 

Cesarean  section  on  the  dead  woman  has  been  done  for  ages,  possibly  even  by  the  early 
Egyptians,  and  the  operation  is  referred  to  in  the  myths  and  folklore  of  European  races.  Dionysus 
was  cut  from  the  dead  Semele.  The  Lex  Regia  of  Numa  Pompilius,  715  B.  c,  expressly  commands 
the  removal  of  the  child  before  the  burial  of  its  mother. 

Cesarean  section  on  the  living  is  of  more  recent  date,  though  it  is  more  than  possible  that  it 
was  performed  by  earlier  peoples.  "Jotze  Dofan"  was  the  name  the  ancient  Jews  applied  to 
children  delivered  through  the  flanks  of  their  mothers.  In  the  heart  of  Uganda  in  1879  Felkin 
witnessed  a  cesarean  section  performed  by  a  native.  The  operator — a  specialist — washed  his 
hands  and  the  operative  field  with  banana  wine  (antisepsis!),  the  patient  being  drunk  with  the 
same  (anesthesia!).  A  quick  incision  opened  the  uterus.  After  cutting  the  cord  and  removing 
the  placenta  the  cervix  was  dilated  from  above,  the  uterus  massaged  and  compressed,  the  peritoneal 
cavity  cleansed  by  raising  the  woman  up,  then  the  abdomen  closed  by  pin  and  figure-of-8 
sutures,  the  wound  being  dressed  with  a  paste  of  crushed  herbs.  The  temperature  remained  below 
101°  and  the  wound  healed  in  eleven  days.  For  how  many  centuries  must  these  savages  have  been 
doing  this  operation  to  have  developed  so  good  a  technic? 

The  first  generally  accepted  cesarean  section  was  made  by  J.  Trautman,  of  Wittenberg,  in 
1610,  on  a  case  of  hernia  uteri  gravidi.  About  1500  J.  Nufer,  a  swinegelder  in  Switzerland,  had 
successfully  delivered  his  own  wife  after  a  dozen  midwives  and  several  barbers  had  failed,  and  in 
1581  F.  Rousset  had  published  15  cases,  which  probably  were  not  all  extra-uterine  pregnancies, 
as  has  been  suggested.  Rousset's  monograph  established  the  operation,  and  in  spite  of  its  own 
frightful  mortality  and  the  resultant  opposition  by  many  of  Europe's  best  accoucheurs,  it  very 
slowly  became  an  acceptable  resource  in  those  forlorn  cases  where  the  parturient  almost  to  a 
certainty  would  have  died  without  it  The  Catholic  Church  had  much  to  do  with  the  habilitation 
of  the  operation,  since  it  enabled  the  rite  of  baptism  to  be  given  to  the  child.  Sigault's  symphj'si- 
otomy  for  a  few  years  only  was  a  competitor  of  cesarean  section. 

Kayser  (Copenhagen,  184-1)  found  a  mortality  of  62  per  cent,  for  the  previous  eighty  years, 
but  Tarnicr  said  that  up  to  his  time  there  had  not  l)een  a  successful  case  in  Paris  during  the  nine- 
teenth century,  and  Spaeth  said  the  same  thing  of  Vienna  in  1877.  Harris  collected  80  cases  in  the 
United  States,  with  a  mortality  of  52  per  cent.  The  causes  of  death  were  hemorrhage  and  infection. 
In  cesarean  sections  sutures  were  not  put  in  the  uterine  wound  because  the  ends  could  not  be  left 
long  for  the  subsequent  removal,  as  was  the  custom  in  olden  days.  As  a  result  the  women  often  died 
of  hemorrhage  into  the  peritoneal  cavity.  For  the  same  reason  lochia  escaped  into  the  belly  and  usu- 
ally set  up  peritonitis.  Further,  aseptic  te(;hnic  was  unknown,  and  all  laparotomies  were  fearfully 
dangerous.  In  176!)  Lebas  put  tiu'ee  stitclies  in  the  uterine  wound  and  left  tlie  ends  long,  by  which 
they  weresul^sequently  removed,  with  success,  but  a  true  efficient  uterine  suture  was  not  made  until 
Sanger  recommended  it  in  1882.  In  1877  Porro,  of  Pavia,  to  avoid  the  dangers  of  hemorrhage  and 
of  infection  from  the  leaking  of  the  lochia,  advised  the  supravaginal  amputation  of  the  uterus  after 
the  child  was  delivered,  and  for  a  short  time  this  operation  bid  fair  to  replace  the  old  conservative 
cesarean  section.  Sanger's  operation  in  1882  showcnl  such  good  results  that  Porro's  was  soon 
relegated  to  its  proper  place — as  an  operation  where  there  is  .some  special  indication  for  sacri- 
ficing the  uterus.  The  essentials  of  Sanger's  operation  are:  median  al)d()niinal  incision;  median 
uterine  incision,  with  or  without  eventration  of  the  uterus;  use  of  rubber  ligature  around  cervix 
to  stop  hemorrhage;  rese(;tion  of  a  strip  of  uterine  muscle  under  the  peritoneum;  interrupted 
silver-wire  seromuscular  sutures,  avoiding  tlie  decidua — 8  or  10;  interrupted  fine  silk  seroserous 
(Lembert)  suture,  20  to  25;   extreme  antisepsis. 

Previous  to  Sanger  the  abdominal  incdsion  had  been  made  in  all  possible  locations,  th(>  uterus 
opened  in  many  different  places  and  ways,  drainage  of  the  uterus,  of  the  abdominal  cavity,  above 
and  below,  and  many  other  devices  had  been  practised.  The  objec^t  was  to  avoid  hemorrhage, 
seepage  of  lochia,  adhesions  of  the  uterus  to  the  abdominal  wall,  to  the  omentum,  with  the  danger 
of  rupture  of  the  scar  in  sui)sequent  ijregnancies.  \\'itli  the  general  imi)r()veiiieiit  of  our  aseptic; 
technic  the  results  of  Sanger's  operation  got  better,  and  it  was  found  possiljle  to  dispense  with 

990 


CESAREAN    SECTION  991 

many  things  he  considered  necessary.  Many  varieties  of  suture  have  been  recommended,— 
through-and-through  interrupted  or  continuous,  buried  muscular,  seromuscular,  decidual,  three 
layers,  four  layers,  silkworm-gut,  wire,  silk,  catgut,  etc.  We  cannot  describe  them  all,  but 
will  give  the  technic  as  practised  today. 

Indications  for  Conservative  Cesarean  Section. — These  are  absolute  and  rela- 
tive. The  absolute  indication  for  cesarean  section  exists  when  the  parturient  canal 
is  narrowed  so  much  that  the  child,  even  reduced  by  mutilating  operations,  cannot 
be  gotten  through  with  safety  to  the  mother.  Contracted  pelvis  with  a  conjugata 
vera  of  6  or  63^2  cm.  or  an  immense  child  will  give  the  absolute  indication,  but  the 
narrowing  of  the  passage  may  be  produced  by  exostoses,  irremovable  tumors, 
stenosis  of  the  cervix,  vagina,  and  neoplasms  of  the  uterus  and  adnexa,  prolapsed 
before  the  child.  If  these  conditions  are  discovered  early  in  pregnancy,  many  may 
be  removed  before  labor,  or  at  least  abortion  may  be  done.  In  labor  there  is  no 
choice. 

The  relative  indication,  speaking  broadly,  will  exist  when  the  accoucheur  de- 
cides that  the  abdominal  delivery  offers  better  chances  for  both  mother  and  child 
than  delivery  from  below.     It  is  largely  subjective. 

In  contracted  pelvis,  excepting  the  abfsolutel}^  contracted,  cesarean  section  is 
considered  only  with  a  view  to  saving  the  life  of  the  child,  because  we  can,  by  means 
of  embryotomy,  very  safely  deliver  from  below.  The  field  claimed  for  cesarean 
section  from  the  relative  indication  is  in  pelves  with  a  conjugata  vera  of  from  6}4  to 
9  cm.,  depending  on  the  size  of  the  child.  This  is  also  the  field  claimed  by  pubiot- 
omy,  prophylactic  version,  forceps,  and  expectancy.  This  brings  us  again  to  the 
treatment  of  contracted  pelvis.  (See  pp.  709-715.)  "When  the  woman  is  in 
prime  condition,  which  means  that  she  is  not  infected  and  not  exhausted  by  long 
labor,  and  when,  also,  the  child  is  in  good  condition,  my  preference  is  for  cesarean 
section.  If  the  woman  has  been  examined  by  questionable  hands;  if  she  has  been 
in  labor  many  hours;  if  the  bag  of  waters  has  been  open  a  long  time;  if  attempts 
at  delivery  have  been  made — cesarean  section,  while  not  always  positively  contra- 
indicated,  is  a  risky  operation,  and  I  do  not  perform  it  under  such  circumstances. 
Pubiotomy,  high  forceps,  and  craniotomy  should  be  considered.  If  the  woman  is 
infected,  as  shown  by  fever,  fetid  liquor  amnii,  tympania  uteri,  necrotic  areas  on  the 
vulva,  cesarean  section  from  the  relative  indication  is  absolutely  forbidden.  For- 
tunately, under  these  circumstances  the  child  has  nearly  always  already  succumbed, 
so  that  one  may  devote  all  his  efforts  to  save  the  mother. 

Placenta  prsevia  as  an  indication  for  abdominal  delivery  has  latterly  been  much 
discussed,  and,  as  was  already  said,  my  opinion  is  in  favor  of  it  when  the  patient 
is  at  or  near  term,  in  good  condition, the  child  alive,  and  the  placentacentralorlargely 
covering  the  os.  Eclampsia,  at  or  near  term,  with  the  os  tightly  closed,  proposed 
by  Halbertsma  as  an  indication,  has  received  few  supporters,  ^'aginal  cesarean 
section  is  usually  preferable,  but  if  the  woman  is  at  term  or  near  it,  if  the  cervix 
is  long  and  hard,  if  the  parametria  are  edematous,  or  if  the  hemorrhage  while  operat- 
ing below  is  too  great, — as  happened  with  one  of  my  cases, — the  abdominal  route  is 
better. 

Abruptio  placentae  is  a  proper,  though  rare,  indication  for  cesarean  section  when 
the  birth-passages  are  totally  unprepared,  if  the  woman  is  in  a  maternity  or  can  l)e 
gotten  there  in  time.  Prolapse  of  the  cord,  in  the  absence  of  contraction  of  the 
pelvis  or  other  contributing  indication,  will  hardly  be  admissible  as  a  reason  for 
the  abdominal  delivery,  though  one  can  imagine  cases  where  it  would  be  justifiable. 

Nowadays,  cesarean  section  is  so  safe  that  it  is  freely  performed,  where  formerly 
it  would  not  have  been  even  thought  of.  In  49  cases  of  my  own  the  following  were 
the  indications:  Contracted  pelvis,  32;  placenta  prsevia,  3;  eclampsia,  2;  stenosis 
of  cervix,  1;  vaginofixation  of  uterus,  1;  slightly  contracted  pelvis,  scars  in  cervix, 
and  placenta  prsevia,  1;  vaginal  scars  with  pelvic  abscess,  1;  healed  vesico-uretero- 
vaginal  fistula,  1;    contracted  pelvis  and  mammoth  child,  1;    manmioth  child,  2; 


992  OPERATIVE    OBSTETRICS 

ovarian  cyst  in  small  pelvis,  1;  fibroids  and  infection,  1;  fibroids  and  contracted 
]:)elvis,  1;   habitual  death  of  fetus  in  labor,  1. 

Reynolds  and  Newell  in  Boston  believe  that  the  abdominal  delivery  is  pref- 
erable to  a  hard,  or  possibly  instrumental,  labor  through  the  natural  passages  in 
cases  where  the  woman  is  unfit,  as  regards  her  nervous  constitution  and  general 
makeup,  to  stand  the  strain  of  labor.  While  at  the  first  impression  this  seems  ex- 
treme, it  is  certain  that  every  accoucheur  of  experience  will  recall  cases  where  the 
profound  prostration  and  nervous  shock  of  even  spontaneous  deliveries  have  left 
permanent  traces  in  the  woman's  life.  In  my  opinion  the  psychic  influence  of 
labor  should  be  given  a  prominent  place  in  our  deliberations  when  selecting  a  mode 
of  delivery. 

Conditions. — For  the  absolute  indication  there  are  no  governing  conditions — 
the  child  must  be  removed  abdominally  whether  or  not  it  is  alive,  and  regardless  of 
the  condition  of  the  patient.  If  she  is  infected,  extirpation  of  the  uterus  should 
follow. 

For  the  relative  indication  to  hold,  the  mother  and  babe  should  be  in  prime 
condition.  It  is  very  important  to  make  sure  that  the  child  is  not  a  monstrosity, 
as  an  acephalus,  which  is  not  easy.  One  may  now  get  an  a:-ray  picture  of  the 
child.  In  the  presence  of  kidney,  lung,  heart,  or  general  diseases  the  questions 
of  risk  of  anesthetic,  of  shock,  and  of  infection  must  receive  careful  consideration 
with  a  medical  consultant.  In  the  presence  of  infection  the  relative  cesarean  sec- 
tion is  contraindicated.     Gonorrhea  comes  in  this  class. 

The  cervix  must  be  patulous  for  the  escape  of  the  lochia;  if  there  is  cicatricial 
stenosis,  the  uterus  must  be  removed.  It  is  best  to  operate  when  the  woman  has 
had  regular  labor  pains  for  an  hour  or  more.  Barnes  (1876)  advised  to  operate 
just  before  labor  began,  in  order  to  avoid  the  disadvantages  of  emergency,  a  plan 
also  recommended  by  Bar.  The  objections  to  this  are:  Hemorrhage  from  the 
uterus  is  greater,  a  few  deaths  having  occurred  in  former  days;  the  uterus  in  prema- 
ture labor  does  not  contract  well;  the  cervix  is  closed,  and  drainage  is  poor;  it  is 
difficult  to  determine  the  exact  date  of  term,  and  a  premature  infant  or  premature 
twins  may  be  delivered.  The  advantages  of  operating  before  labor  has  begun  are : 
Everything  can  be  gotten  ready  without  hurry,  as  for  ordinary  laparotoni}-,  which 
means  much  for  the  assistants  and  nurses;  operation  by  daylight;  the  accoucheur 
can  usually  have  had  some  rest;  the  bag  of  waters  is  still  intact;  the  cord  or  ex- 
tremities will  not  have  prolapsed;  accidents  and  delay's  in  transportation,  etc.,  are 
avoided. 

By  the  prophylactic  administration  of  ergot,  the  injection  of  epinephrin  and 
perhaps  pituitrin,  by  packing  the  uterus  with  wet  hot  pads,  brisk  kneading,  and 
compression  of  the  aorta  the  hemorrhage  is  controllable;  by  dilating  the  cervix 
drainage  of  the  uterus  may  be  provided,  and  by  careful  study  of  the  cases  the  proper 
time  for  the  operation  may  be  determined.  I  often  operate  before  labor  begins. 
When  a  Porro  is  to  be  performed,  the  element  of  danger  from  hemorrhage  and  lochial 
seepage  is  eliminated,  and,  therefore,  the  operation  may  be  undertaken  at  any  time. 

Technic. — It  is  important  to  get  the  patient  into  the  best  possible  general  health  beforehand. 
Regulated  outdoor  exercise,  care  of  the  bowels,  and  much  sleep  are  provided.  The  skin  of  the 
belly  sliould  be  cured  of  eczematous  and  other  eruptions.  As  a  routine  may  be  recommended  daily 
washing  of  the  belly  with  tincture  of  green  soap.  Douches,  without  special  indication,  are  for- 
l)idden,  and  the  patient  is  impressed  with  the  importance  of  local  cleanliness  and  the  abstinence 
from  intercourse  or  self-examination.  If  possible,  she  should  be  in  the  maternity  a  week  or  more 
in  advance  of  the  date  set.  General  diseases — for  example,  nepliritis,  hemophilia — are  treated 
as  thoroughly  as  we  know  how.  Gentle  laxatives  are  used  a  few  days  before,  and  an  enema  the 
day  of,  the  operation. 

The  Operation. — Fig.  881  shows  the  instruments  required. 

Preparations  for  reviving  the  child  should  never  be  forgotten.  Four  assistants  are  needed — 
one  for  the  anesthetic,  one,  specially  trained,  to  resuscitate  the  child,  one  to  help  on  the  other  side, 
and  one  to  hand  instruments,  thread  needles,  supply  sponges — duties  which  in  most  modern 
hospitals  fall  to  the  nurse.  Another  sterile  assistant  may  be  needed  if  the  case  is  complicated  or 
requires  extirpation  of  the  uterus. 


CESAREAN    SECTION

Straight  ether  is  the  best  anesthetic.  In  two  cases  operated  under  the  gas-oxj'gen  method 
the  experience  was  not  satisfactory,  the  venous  oozing,  rigidity  of  the  abdominal  walls,  and  strain- 
ing of  the  patient  being  very  troublesome.  If  this  method  is  employed,  the  gas  may  not  be  started 
until  the  operator  is  ready  to  make  the  incision,  and  delivery  must  be  very  rapid  or  the  child  will 
be  asph3^xiated.     Several  cesarean  sections  have  been  done  under  local  anesthesia. 

For  the  preparation  of  the  abdomen  I  still  adhere  to  the  old  method — shaving,  washing 
thoroughly  with  tincture  of  green  soap  and  hot  water,  with  bichlorid  1:10()0,  with  95  per  cent, 
alcohol,  and  leaving  a  towel  soaked  in  1:1000  bichlorid  on  the  belly  until  the  laparotomy  sheet  is 
put  on,  then  wiping  tlie  field  again  with  95  per  cent,  alcohol.  The  iodin  method  shows  favorably 
in  the  reports,  but  I  have  feared  that  the  free  iodin  would  get  into  the  belly  in  the  subsequent 
manipulations  and  cause  peritoneal  adhesions  and  ileus. 

Just  before  starting  the  anesthetic  a  hypodermic  of  aseptic  ergot  is  given  and  the  patient 
catheterized.  The  inci-sion  is  made  in  the  Hnea  alba,  should  be  about  o^  o  inches  long,  with  its 
middle  about  at  the  navel  and  a  little  to  the  left  of  the  latter.  In  the  New  York  Ljing-in  Hospital 
the  opening  is  made  high  above  the  navel.  As  the  belly-wall  is  sometimes  very  thin,  one  may  not 
cut  too  deeply.     It  is  best  to  make  a  small  opening  and  cut  the  balance  with  scissors  on  two  fingers

inserted  into  the  peritoneal  cavity.  Xow  the  uterus  is  brought  to  the  middle  line  and  steadied 
by  the  assistant.  With  another  knife  a  longitudinal  incision,  5  inches  long,  corresponding  to  the 
abdominal  one,  is  made  half  through  the  thickness  of  the  uterine  wall,  and  with  lessening  strokes 
the  cavity  of  the  egg  is  opened;  then,  cutting  between  two  fingers  with  scissors,  the  opening  is 
enlarged  both  ways  to  the  size  of  the  first  uterine  cut.  Liquor  amnii  gushes  out  while  the  operator 
searches  for  one  foot,  on  which  he  makes  the  breech  extraction,  following  minutely  the  classic 
operation  with  Smellie-^'eit  on  the  after-coming  head.  The  assistant  presses  the  sides  of  the  belly 
against  the  retracting  uterus  to  keep  liquor  amnii  and  blood  out  of  the  peritoneal  cavity.  Clamp- 
ing the  cord  in  two  places  and  cutting  between  requires  only  an  instant,  the  operator  handing  the 
child  to  an  a.ssistant  who  stands  at  his  elbow  bearing  a  large  tray  covered  with  an  aseptic  blanket. 
Xow  the  uterus  is  dehvered  through  the  wound,  and  a  large  wet  towel  or  laparotomy  pad  placed 
beneath  it  to  catch  the  blood  and  to  prevent  the  exit  of  the  intestines  and  omentum,  or,  if  the 
patient  is  straining,  the  wall  may  be  temporarily  united  by  three  bullet  forceps.  The  placenta 
usually  falls  free  into  the  hollow  of  the  uterus,  but  the  membranes  must  be  pulled  off,  genth'  and 
slowly  to  get  them  all.  The  most  important  part  of  the  operation  is  the  uterine  suture.  After 
the  secundines  are  out,  with  a  gauze  pad  the  interior  of  the  uterus  is  thoroughly  wiped  smooth,

OPERATIVE    OBSTETRICS 


all  shreds  of  placenta  and  membranes  being  removed,  and  a  clean  pad  is  stuffed  into  the  gaping 
cavity,  which  rapidlj^  closes  as  the  organ  retracts  and  contracts.  This  is  aided  by  brisk  kneading 
and  firm  compression.  The  first  row  of  sutures  takes  in  the  muscle  near  the  endometrium,  it 
being  better  not  to  puncture  the  decidua,  although  in  clean  cases  there  is  little  objection  to  so 
doing.  The  stitches  are  placed  one-half  incli  apart  and  are  continuous — No.  2  twenty-day  catgut. 
The  hemorrhage  is  much  less  when  this  layer  of  sutures  is  in  place,  and  the  wall  of  the  uterus  is 
much  thicker  l\v  this  time.  It  is  usually  possible  to  determine  three  layeis  of  muscle — one,  the 
thickest,  internal,  next  to  the  decidua,  and  darker  in  color,  prol)al)ly  because  the  fibers  are  cut 
across;  another,  a  little  thinner — the  middle  coat;  and  a  third,  very  thin,  to  which  is  attached  the 
peritoneum.  The  second  row  of  sutures  should  take  in  the  middle  coat  and  is  entirely  buried. 
It  is  of  Xo.  2  twenty-day  catgut,  continuous,  the  stitches  being  about  1  cm.  apart.  The  knots 
should  be  particularlj'  well  tied,  and  not  too  much  constriction  of  the  tissues  made,  or  else  necrosis 
of  the  tissues  will  result.  The  third  or  peritoneal  suture  is  made  with  a  smooth  needle,  using  No. 
1  catgut,  and  takes  in  the  peritoneum  and  a  little  of  the  muscular  tissue.  It  is  also  continuous. 
It  may  be  mad(>  subperitoneal,  similar  to  (he  subcuticular  suture.  Each  row  of  sutures  is  begun 
at  the  end  of  the  wound  opposite  that  of  the  last.  If  the  wall  is  very  thick,  four  layers  of  stitches 
may  be  applied.     Time  taken  to  apply  an  accurate  uterine  suture  is  well  spent. 

Now  the  uterus  is  replaced,  the  peritoneal  toilet  is  made,  the  small  intestines  pulled  up  out

of  the  pelvis,  the  omentum  dra\\Ti  dowm  behind  the  uterus,  and  the  abdominal  wall  closed  -nnth  three 
or  four  layers  of  sutures.  I  usually  use  No.  2  chromicized  catgut,  double  thread,  for  the  fascia, 
and  continuous  silkworm-gut  for  the  skin.  Catgut  is  not  an  entirely  satisfactory  suture  for  the 
abdominal  wall,  and  it  is  a  good  plan  to  insert  2  or  3  tension  suture.^  through  the  skin  and  fascia. 

While  cesarean  section  is  a  simple  operation,  to  attain  success  requires  a  subtle  technic  and 
close  attention  to  every  dcjtail. 

Complications. — Ail/i(:\ions  are  seldom  met  in  primary  operations,  but,  nevertheless,  it  is 
w4.se  not  to  cut  too  boldly  into  the  belly.  After  previous  .sections  adhesions  are  the  rule.  The 
most  common  are  of  the  omentum,  or  of  the  uterus  to  the  abdominal  wall,  or  the  omentum  to  the 
uterus.  Rarely  a  coil  of  gut  is  attached  to  the  uterus  under  the  line  of  the  incision,  and  still  more 
rarely  the  cecum,  appendix,  or  sigmoid  may  be  adherent  behind  and  tear  when  the  uterus  is  even- 
trated.  Where  adhesions  are  known  or  susp('cted,  tli(>  belly  should  be  opened  at  a  spot  free  from 
them,  and  two  fingers  inserted  to  determine  their  location  and  extent.  A  clear  space  on  the  uterus 
should  be  quickly  made,  and  the  child  and  i)lacenta  delivered,  after  which  the  adiiesions  are  dealt 
■with  according  to  general  surgical  principles.  It  is  best  not  to  deliver  the  uterus  if  there  are  ad- 
hesions. Adherent  gut  must  l)e  very  tenderly  handl(>(l.  If  the  omentum  can  be  tied  off  the  uterus 
or  abdominal  wall  without  denuding  it  much,  this  sliould  be  done — large  rough  areas,  however, 
only  invite  new  adhesions.  If  the  uterus  is  intimately  bound  to  the  abdominal  fa.seia,  it  may  be 
best  not  to  attempt  its  separation  unless  extirpation  of  the  organ  is  to  be  performed  or  the  tubes 


CESAREAN    SECTION  995 

exsected.  In  the  latter  instance  a  segment  of  the  uterus,  together  with  the  abdominal  scar,  may  be 
excised.  In  a  second  cesarean  section  the  uterine  incision  should  be  parallel  to  and  close  to  the 
scar  of  the  first  one,  or  in  another  part  entirely — for  example,  the  fundus,  after  Fritsch. 

If  a  hernia  of  the  old  scar  is  present,  the  sac  is  to  be  exsected  and  the  edges  of  the  fascia 
brought  together  anew. 

The  Placenta. — In  27  of  40  cases  where  the  site  of  the  placenta  was  noted  the  organ  was 
situated  on  the  anterior  wall  and  had  to  be  cut  to  gain  access  to  the  infant.  It  is  not  po.ssible  to 
be  sure  of  the  location  of  the  placenta  beforehand.  The  course  of  the  round  ligaments  (converging 
anteriorlj')  and  the  prominence  of  the  veins  in  the  \'iolaceous  surface  of  the  uterus  give  some  indi- 
cation of  it.  If  the  first  cut  into  the  muscle  causes  profuse  hemorrhage,  anterior  insertion  may  be 
suspected,  but  the  operation  docs  not  differ  from  the  usual  one,  except  that  the  movements  must 
be  hastened.     I  u.sually  cut  right  through  the  placenta. 

Hcniurrhar/f-. — Where  the  placenta  is  cut  or  torn,  bleeding  is  usually  profuse,  both  during  the 
delivery  and  afterward.  A  prophylactic  hj-podermic  injection  of  20  minims  of  aseptic  ergot  is  a 
routine  before  the  anesthetic  is  started ;  as  soon  as  the  child  is  delivered  the  placenta  is  to  be  removed, 
taking  care  to  get  all  the  membranes;  then  the  uterus  is  kneaded  briskly  between  the  two  hands, 
while  it  is  covered  with  pads  wrung  out  of  very  hot  salt  solution.  The  inner  surface  is  wiped  smooth 
with  a  pad  wrung  out  of  hot  salt  solution,  and  the  uterus  held  tightly  in  the  grasp  for  a  minute. 
The  quickest  way  to  stop  the  bleeding  is  by  closing  the  uterine  wound,  which  should  be  done  with 
the  utmost  despatch.  Then  the  massage  is  repeated.  If  this  does  not  suffice,  four  drops  of 
epinephrin  1 :  10,000  are  injected  directly  into  the  muscle  in  two  or  three  places,  making  about  ten 
drops  in  all.  ^^'hile  these  manoeuvers  are  being  carried  out,  an  a.ssistant  compresses  the  aorta, 
as  shown  in  Fig.  717.  If  these  measures  do  not  quickly  cause  uterine  contraction  and  cessation  of 
the  bleeding,  extirpation  of  the  uterus  must  be  considered.  The  operator  must  not  forget  that 
the  blood  maj'  escape  per  vaginam  also  and  in  large  quantities.  If  it  is  desirable  to  preserve  the 
uterus  and  the  hemorrhage  persists,  uterine  tamponade  may  be  resorted  to.  Since  the  wound  has 
been  closed,  packing  is  inserted  from  below  in  the  usual  manner.  On  two  occasions  I  deemed  it 
best  to  tampon.     Recovery. 

Infection. — If  the  case  is  known  to  be  infected,  the  conservative  cesarean  section  is  contra- 
indicated,  and  if  delivery  must  be  made  abdominally,  either  the  Porro  operation  or  complete 
extirpation  must  be  practised.  In  cases  of  gonorrhea  conservative  section  is  very  dangerous,  a 
point  Leopold  emphasizes,  and  it  is  best  to  consider  these,  too,  infected.  There  is  no  way  of  de- 
termining beforehand  that  the  parturient  canal  is  aseptic.  Fever,  fetid  discharge,  tj-mpania  uteri, 
and  unhealthy  wounds  at  the  introitus  are  evidences  of  infection  of  the  uteru.s — at  least,  are 
danger-signals.  In  border-line  cases  the  technic  must  be  modified.  Here  the  incision  is  made 
longer,  the  uterus  delivered  out  of  the  belly,  and  the  latter  closed  temporarily  behind  it  by  three 
bullet  forceps  over  which  several  large  pads  or  towels  are  placed.  A  scjuare  yard  of  dentists' 
rubber  dam  with  a  three-inch  slit,  sterilized  beforehand,  is  now  placed  around  the  uterus  in  the 
same  way  as  the  dentist  dams  off  a  tooth.  Under  these  precautions  the  uterus  is  opened  and  closed. 
Before  returning  it  to  the  belly  it  is  washed  with  salt  solution;  the  operator  and  assistants  change 
their  gloves,  and  a  clean  lap-sheet  is  spread  over  the  field.  If,  during  an  ordinary  cesarean  section, 
a  septic  focus  is  unexpectetlly  opened,  for  example,  an  infected  dermoid,  the  intestine,  an  appendi- 
ceal abscess,  it  is  best  to  remove  the  uterus  and  provide  free  pelvic  drainage. 

Uterine  Drainage. — While  rubbing  the  interior  of  the  uterus  smooth,  it  is  a  good  plan  to 
pass  the  finger  do\\Ti  into  the  cervix,  but  not  through  it  into  the  vagina,  to  see  if  it  is  patulous,  unless 
examination  beforehand  has  sho\\'n  that  the  os  is  open.  If  the  cervix  is  closed  by  scars  so  that  a 
crow's  ciuill  cannot  pass,  the  uterus  is  to  be  amputated.  A  normal  cervix  will  open  spontaneously 
under  the  influence  of  the  after-pains.  If  the  accoucheur  fears  that  there  is  not  enough  drainage, 
he  may  pass  gauze  or  a  tube  through  the  cervix  into  the  vagina.  It  is  highly  important  not  to 
catch  the  gauze  in  the  uterine  stitches.     One  fatality  from  this  cause  is  on  record. 

After-treatment. — This  does  not  differ  from  -that  after  the  usual  laparotomy.  I  give  10 
minims  of  ergot  four  times  a  day  for  a  week.  Cathartics  are  usuallj'  not  administered  until  the 
fifth  to  the  eighth  day,  and  then  not  unless  required,  the  bowels  being  unloaded  by  enemata.  Milk 
and  molasses,  1  pint  of  each,  make  a  very  efficient  clj-ster,  which  may  be  repeated.  Sometimes 
camomile  tea  produces  a  free  evacuation  of  feces  and  flatus.  The  baby  is  put  to  the  breast  at 
the  end  of  twelve  to  twentj'-four  hours. 

Of  the  various  postoperative  complications,  peritonitis,  ileus,  and  uterine  abscess  only  will 
be  mentioned.  If  a  beginning  peritonitis  is  diagnosed,  the  patient  must  be  constantlj^  watched, 
that  is,  hourly  observations  must  be  made,  and  if  the  pulse  grows  steadily  faster,  the  nausea  in- 
creases to  emesis,  the  temperature  rises  higher,  the  abdominal  rigidity  increasing,  with  or  without 
leukocytosis — in  short,  if  the  observer  is  convinced — and  the  time  required  to  know  seldom  need 
exceed  eight  hours — that  the  infection  is  progressing,  the  belly  is  to  be  reopened  and  drained.  Ileus 
and  acute  dilatation  of  the  stomach  occur,  it  seems  to  me,  oftener  after  cesarean  section  than  after 
other  celiotomies.  For  ileus  the  usual  methods  of  treatment  are  practised.  One  that  is  service- 
able after  cesarean  section  is  to  hang  the  woman,  inverted,  from  the  shoulders  of  assistants,  and 
with  the  finger  in  the  rectum  push  the  heavy  uterus  up  out  of  the  pelvis,  and  gi\e  a  high  colonic 
flushing  of  milk  and  molasses,  -n-ith  the  patient  depending.  In  one  case  an  electric  vibrator  apphed 
to  the  distended  bowel  seemed  to  help.  Eserin  had  failed.  The.se  measures  have  been  successful 
in  my  practice  in  the  treatment  of  gastric  dilatation;  having  the  woman  lie  on  the  stomach,  the 
foot  of  the  bed  being  elevated  IS  to  24  inches;  gastric  lavage,  repeated  every  four  to  six  hours; 
massage  of  the  stomach;  rectal  feeding.  Both  ileus  and  dilatation  may  be  caused  by  a  too  tight 
abdominal  binder,  a  point  that  I  would  emphasize  strongly.  In  all  probability  a  mild  peritoneal 
infection  is  responsible  for  most  of  the  cases,  and  bursting  of  the  fascial  suture  for  a  few  others. 
Uterine  abscess  is  a  not  infrequent  complication,  and  is  to  be  suspected  if  there  is  a  mild  fever, 


996  OPERATIVE    OBSTETRICS 

with  signs  of  local  peritonitis  or  partial  ileus.  Usually  the  abscess  breaks  on  the  surface,  the  wound 
opening.  With  good  drainage  the  patient  quickl}'  recovers,  but  the  uterus  is  permanently  ventro- 
fixed  and  the  scar  may  give  way  in  a  subsequent  pregnancy. 

Prognosis. — Bj-  rigid  examination  of  the  cases  and  the  exclusion  of  all  that  present  even  a 
suspicion  of  infection,  the  mortality  of  the  conservative  cesarean  deliver}-  can  be  reduced  to  almost 
nothing.  Series  of  20  to  39  cases  without  death  have  been  reported.  Routh,  in  1910,  collected 
•nith  great  labor  the  statistics  of  Great  Britain,  comprising  12S2  cases,  and  these  may  be  taken  as 
a  type  for  all  civilized  countries.  He  shows  that  there  has  been  a  steadj^  decrease  in  mortality 
until  now,  in  favorable  cases,  it  is  from  2  to  4  per  cent.  In  cases  where  labor  had  been  prolonged 
or  even  attempts  made  yrith  the  forceps,  the  death-rate  was  34  per  cent,  and  over.  After  labor 
had  been  in  progress  some  time  with  the  membranes  ruptured  he  found  10.8  per  cent,  mortality, 
the  best  showing  being  made  in  those  cases  where  labor  had  just  begun,  the  bag  of  waters  being 
intact — 2.2  per  cent.  It  is  generally  admitted  that  the  dangers  of  cesarean  section  increase  with 
every  hour  the  woman  labors,  especially  if  the  membranes  are  opened.  The  exhaustion  of  active 
labor  diminishes  the  woman's  vital  resistance  to  infection.  Routh  gives  the  general  mortality 
of  cesarean  section  for  all  indications  as  ll.G  per  cent.,  and  if  one  takes  only  the  last  five  years, 
it  is  S.l  per  cent.  In  spite  of  most  rigorous  asepsis  and  a  perfect  technic,  the  operation  has  a  high 
morbidit3\  Infected  suture  matei-ial  has  caused  the  most  troul)le  in  my  cases,  and  the  secondary 
union  has  been  followed  by  four  hernias  that  I  know  of.  Ten  of  the  49  cases  had  severe  febrile 
reactions,  1,  marked  peritonitis  (relaparotomy,  recovery),  3,  postoperative  pneumonia,  4,  uterine 
abscess,  and  there  were  2  cases  of  temporary  ileus,  2  of  dilatation  of  the  stomach  (all  4  with  alarm- 
ing sj-mptoms).  Two  women  died,  one  from  peritonitis  and  one  had  nephritis,  the  operation  being 
done  for  eclampsia.  There  were  49  cases,  including  Porro  cesareans.  Taken  all  in  all,  it  is  not  an 
operation  to  be  lightly  advised.  The  mortality  of  the  children  should  be  zero  if  the  infant  was  well 
at  the  start.     One  baby  of  the  49  died  from  asphyxia — a  lapsus  artis. 

Repeated  cesarean  sections  have  been  done  in  large  numbers,  Nancrcde  in  1S75  having  done 
the  sixth  operation  on  the  same  woman.  In  such  cases  the  uterus  is  so  broadly  adherent  to  the 
belly-wall  that  it  may  be  opened  without  entering  the  general  peritoneal  cavity.  I  do  not  recom- 
mend to  try  this  because  intestines  maj'  be  adherent  to  the  scar.  Seven  of  my  cases  were  second 
operations.  Polak,  in  1909,  collected  150  cases  of  repeated  section,  which  showed  a  mortalitj^  of 
less  than  5  per  cent.,  which  is  as  good  as,  if  not  better  than,  the  primary  cesareans.  In  the  olden 
times,  before  the  uterus  was  sutured,  rupture  of  the  scar  in  subsequent  pregnancies  was  not  uncom- 
mon, but  lately,  as  was  showTi  by  Brodhead,  the  accident  has  become  quite  rare,  and  this  is  because 
the  uterus  is  sewed  up  better  and  because  in  many  cases  the  patient  is  sterilized.  It  is  important, 
however,  to  have  the  woman  in  a  maternity  in  the  last  few  weeks  of  her  subsequent  pregnancies, 
and  also  to  operate  a  few  days  before  the  expected  onset  of  labor  pains.     (See  Davis.) 

Sterilization  with  Section. — Should  the  woman  be  sterilized  to  prevent  future  pregnancies? 
Authorities  differ  between  wide  extremes,  and  in  deciding  one  must  consider  the  dangers  of  sub- 
sequent pregnancies  and  labors  and  the  necessity  for  consecutive  cesarean  sections. 

If  the  woman  has  tuberculosis,  chronic  nephritis,  osteomalacia,  or  any  disease  which  in  itself 
is  a  contraindication  to  pregnancy,  she  should  be  sterilized.  Any  one  who  admits  the  propriety 
of  inducing  abortion  for  such  conditions  must  admit  the  above  postulate.  Contracted  pelvis  is 
not  allowed  in  this  category. 

The  danger  of  rupture  of  the  uterine  cicatrix  is  no  indication,  because  we  can  avoid  this  by 
properly  sewing  the  uterus,  by  placing  the  patient  in  a  good  maternity  several  weeks  before  labor, 
and  operating  before  pains  set  in. 

If  the  first  section  is  done  for  eclampsia,  placenta  prsevia,  abruptio  placentae,  prolapse  of  the 
cord,  faulty  mechanism  of  labor,  pelvic  tumors,  in  the  absence  of  other  indications  the  woman 
should  not  be  sterilized.  If  the  woman  has  a  large  family,  the  question  is  discussable,  but  if  there 
is  only  one  child,  and  that  one  weak  or  deformed,  it  is  better  not  to  sterilize  her. 

If  the  cesarean  operation  is  done  for  contracted  pelvis,  I  earnestly  dissuade  the  patient  from 
such  a  procedure  at  the  first  section,  pointing  out  the  fact  of  the  safety  of  subsecjuent  operations, 
the  possibility  of  the  death  of  the  only  child,  and  the  unhappiness  of  a  one-child  family.  At  the 
second  cesarean  I  willingly  sterilize,  if  requested,  although  lately,  since  the  mortality  has  been 
so  much  reduced,  I  often  suggest  a  third  operation. 

For  many  years  the  ethics  of  sterilization  have  been  debated.  Green  created  an  extensive 
discussion  of  it  at  the  1903  meeting  of  the  American  Gynecologic  Association,  taking  an  extreme 
negative  position.  Most  American,  English,  and  Continental  authors  concede  the  right  of  de- 
cision to  the  mother  and  her  family,  after  they  have  been  given  a  fair  presentation  of  all  the  facts, 
a  position  which  I  also  take.  By  following  the  Golden  Rule  I  have  had  no  difficulty  in  arranging 
a  satisfactory  course  in  these  matters. 

Methods. — Ligation,  simple  section  or  exsection  of  a  portion  of  the  tube,  as  recommended  by 
Blundell  in  1819,  have  proved  insufficient,  pregnancy  having  occurretl  in  spite  of  tliem.  In  osteo- 
malacia ovariotomy  is  done.  Ablation  of  the  tuljcs  is  safe,  as  is  also  removal  of  wedge-shaped 
pieces  of  the  uterine  horn  containing  the  tubes.  Ihe  method  I  use  is  e.xsection  of  an  inch  of  the 
tube  near  the  uterus  and  burjing  both  ends  securely  under  the  peritoneum  of  the  broad  ligament. 
The  peritoneum  may  be  slit  open,  an  inch  of  the  tube  itself  removed,  the  gap  being  filled  up  ljy  the 
connective  tissue.  It  would  be  po.ssible,  should  pregnancy  be  later  desired,  to  reopen  the  belly  by 
anterior  colpotomy  and  anastomose  the  cut  ends  again.  Extirpation  of  the  uterus  as  a  means  of 
simple  sterihzation  is  hardly  to  be  recommended,  certainly  not  in  young  women.  The  desire  to 
have  all  the  functions  of  a  woman  is  strong,  and  seldom  do  the  patients  not  regret  the  lo.ss  of  the 
menses.  I  agree  with  Williams  that  the  operation  can  be  done  in  the  same  time  as  removal  of 
the  tubes,  and  that  the  postoperative  recovery  is  prompter  and  more  satisfactory  than  in  the  con-

servative  cesarean  section,  but  the  technical  difficuUies  are  greater  with  amputation  of  the  uterus, 
and  premature  menopause  is  not  rare,  even  if  one  or  both  ovaries  are  preserved. 

The  Porro  Cesarean  Section.— In  1876  Porro,  of  Pavia,  to  avoid  the  dangers 
of  hemorrhage  and  of  infection  from  the  large  uterus,  which  was  poorly  sewn  up, 
advised  the  amputation  of  the  body  of  the  uterus  and  the  adnexa  above  an  elastic 
ligature  placed  about  the  cervix,  and  the  anchoring  of  the  stump  in  the  lower  angle 
of  the  abdominal  wound— an  operation  similar  to  supravaginal  hysterectomy  for 
fibroid,  with  extraperitoneal  treatment  of  the  stump.  The  operation  had  been 
suggested  by  Blundell  in  1830.  Later,  when  Schroder  dropped  the  sutured  hyster- 
ectomy stump  back  into  the  pelvis,  Isaac  E.  Taylor  did  the  same  for  the  stump  after

^on.  broad  ligaments  are  clamped,  taking  in  the  round  ligaments  if  there  are  varicosities,  which  is  usual. 

Porro's  operation.  Porro's  radical  operation  did  reduce  the  mortality  of  cesarean 
section  and  gained  some  vogue,  but  was  soon  replaced  by  the  improved  conservative 
operation  of  Sanger.     This  was  called  -  conservative  "  because  the  uterus  was  not

present,  especially  if  large  or  if  they  block  the  pelvis.  Myomectomy  may  be  per- 
formed in  favorable  cases  if  the  woman  desires  more  children.  I  did  it  once  ^ath

Uncontrollable  hemorrhage  at  the  time  of  the  cesarean  may  nece&sit ate  amputation 
of  the  fundus.  In  cases  of  ruptured  uterus,  or  one  torn  by  previous  efforts  at  de- 
liverv  and  when  infection  is  present,  it  is  best  to  remove  the  organ.     In  carcinoma 


998 


OPERATIVE    OBSTETRICS 


cervicis  total  extirpation  may  be  practised.  As  a  means  of  simple  sterilization  of 
the  patient  amputation  of  tiie  uterus  is  hardly  recommendable,  though  in  most 
cases,  where  performed,  it  has  been  justifiable. 

There  are  no  conditions.     The  best  time  to  operate  is  before  labor  begins. 

The  technic  is  but  little  different  from  supravaginal  hysterectomy.  If  the  plan  of  operation 
is  known  beforehand,  the  abdominal  incision  should  be  nearer  the  pubis.  After  the  child  is  de- 
livered, two  clamps  are  put  on  each  broad  ligament  close  to  tlie  uterus.     Unless  diseased,  botn

After  cutting  ono  side,  two  clamps  are  placed,  reaching  to  about  the  level  of  the  uterine  artery. 


tubes  and  ovaries  are  left.  Both  round  ligaments  are  also  clamped  separately,  or,  if  they  are  near 
the  tubes,  or  if  the  broad  ligaments  are  full  of  varicose  veins,  they  are  included  in  the  first  clamp. 
After  cutting  to  the  tip  of  the  clamps,  two  more  are  put  on  the  broad  ligaments,  reaching  below  the 
level  of  tlie  uterine  arteries,  keeping  close  to  the  uterus  to  avoid  the  ureters,  and  the  tissue  is  cut 
between.  Now  a  semilunar  incision  is  made  through  tlie  peritoneum  across  the  face  of  tlie  uterus, 
just  above  the  bladder,  extending  from  the  cut  edge  of  the  peritoneum  around  one  round  ligament 
to  the  other,  and  the  bladder  is  pushed  down  by  the  finger  co\ercd  with  a  piece  of  gauze.  Owing 
to  the  usual  immense  development  of  the  veins  of  the  broad  hgament,  the  varicosities  making  it 
sometimes  as  large  as  one's  wrist,  it  is  impractical  always  to  open  up  the  connective  tissue  to  isolate 
the  uterine  arteries,  as  is  done  in  gynecologic  hysterectomies.  After  both  broad  ligaments  are 
clamped  and  the  uterus  freed,  the  latter  is  pulled  sharply  forward  over  the  pubis  and  cut  off,  be- 
ginning from  behind,  just  above  the  vaginal  insertion,  the  point  being  determined  by  palpation.     It 


CESAREAN    SECTION

is  wise  to  out  carefully  because  of  the  softness  of  the  uterine  tissue  and  its  thinness  near  the  bladder. 
I  usually  cut  from  the  right  behind,  to  the  left  in  front,  then  strip  the  uterus  from  the  bladder,  if 
need  be,  forming  a  new  pedicle  of  the  base  of  the  right  broad  ligament,  which  is  clamped  and 
severed  last.  The  ligaments  are  tied  off  under  the  clamps,  using  Xo.  2  hardened  catgut.  Then 
the  large  vessels  are  secured  by  separate  indi\idual  ligatures.  Before  removing  the  clamps  it  is 
wise  to  secure  perfect  hemostasis,  because  oozing  from  the  veins  in  the  soft  tissues  may  Ix'  exceed- 
ingly trouble.some.  A  few  through-and-th rough  sutures  in  the  stump  may  be  required,  but  I 
usually  appl^'  them  in  such  a  manner  as  to  turn  the  cut  edges  of  the  cervix  against  each  other, 


Fig.  887. — Porro  Cesarean  Section. 
A  clamp  is  put  on  the  uterine  artery,  taking  care  that  it  grasps  the  tissue  at  the  side  of  the  uterus,  not  toward  the 

pelvis,  to  avoid  the  ureter. 


leaving  the  cervical  canal  open  for  drainage.  Now  the  peritoneum  is  sewed  together  after  turning 
the  ligated  stumps  in  underneath  it  and  uniting  them  to  the  cervical  stump  with  a  few  sutures. 

]Michaelis,  in  1S09,  recommended  the  removal  of  the  whole  uterus,  and  Bischoff,  in  ISSO,  first 
practised  it — a  case  of  cancer.  The  operation  is  much  more  formidable  than  the  amputation  of  the 
fundus.  The  hemorrhage  from  the  cut  vagina  and  bases  of  the  broad  ligaments  is  less  easily 
controlled. 

Cesarean  section,  \\ith  amputation  of  the  uterus  in  clean  cases,  and  with  an  expert  operator, 
has  the  same  mortality  as  the  conservative  operation,  and  the  morbidity  is  decidedly  less.  In  the 
5  cases  of  my  ovm  recovery  was  prompter,  less  painful,  and  less  complicated  than  after  the  ordinary 
cesarean  operation.     The  reason  for  this  is  the  elimination  of  the  large,  involuting,  really  necros-

ing  uterus,  the  clearing-out  of  the  pelvis  (less  ahsorption),  and  the  covering  in  of  all  raw  surfaces 
by  peritoneum.  In  septic  cases  the  mortality  is  still  high — probably  near  20  percent.  It  is  a 
question  if  total  hysterectomy  would  impro\e  the  results.  If,  during  cesarean  section  in  septic 
cases,  the  abdomen  could  be  closed  tightly  around  the  wjiopcned  uterus  and  the  latter  emptied  and 
amputated  without  soiling  the  peritoneal  cavity,  probably  many  cases  of  peritonitis  could  be 
prevented.     With  a  studied  technic  such  a  result  is  not  unattainable. 

Extraperitoneal  Cesarean  Section. — In  the  olden  time,  wlien  the  dangers  of 
opening  the  belly  were  almost  prohibitive,  the  accoucheur  sought  to  avoid  the 
necessity  of  destroying  the  living  child  by  delivering  it  from  above  the  pelvis,  but 


Fig.  888. — Porro  Ces.\rean  Section. 
After  the  process  has  been  repeated  on  the  right  side,  the  peritoneum  is  severed  one-half  inch  above  its  reflection 
onto  the  bladder.     The  ureter  does  not  come  into  view,  and  lies  a  short  distance  farther  away  from  the  forceps  than 
is  indicated  in  the  drawing. 


without  opening  the  peritoneum.  Joerg  suggested  it  in  1809,  Ritgen  did  it  in  1821, 
as  also  did  Physick,  of  Philadelphia,  in  1824.  In  1870  T.  Gaillard  Thomas  revived 
the  operation,  named  by  Baudclocque,  in  1823,  gastro-elytrotomy.  It  consisted  of 
making  an  incision  above  and  parallel  to  Poupart's  ligament,  blunt  dissection  under 
the  peritoneum  to  the  cervix  and  vagina,  followed  by  a  flank  delivery.  In  1906 
Frank  recommended  a  suprapubic  delivery  after  shutting  off  the  peritoneal  cavity 
by  uniting  the  supravesical  peritoneum  to  the  parietal  peritoneum.  Scllheim  tried 
to  push  the  peritoneum  upward  from  off  the  bladder,  as  was  done  by  Physick,  and 
other  operators,  mostly  German,  modified  the  operation  in  many  ways.  Up  to 
July,  1912,  over  450  operations  had  been  performed,  and  the  method  most  often 
used  was  Latzko's.

by  version  and  extraction,  the  jilacenta  removed  as  usual,  and  the  wounds  carefully 
closed,  with  or  without  alxlominal  or  vaginal  drainage. 

The  dangers  and  inconveniences  of  the  operation  have  already  been  referred

Inc]icatio)}s. — These  are  about  the  same  as  for  conservative  cesarean  section. 
The  hope  that  it  could  l^e  performed  in  septic  and  sus]5icious  cases,  thus  obviating 
the  painful  necessity  of  destroying  the  child  in  contracted  pelvis  with  neglected 
labor,  has  proved  illusory.  Peritonitis  and  ileus  set  in  just  the  same  as  if  the  peri- 
toneum had  been  invaded,  and  if  not  peritonitis,  a  severe  form  of  connective-tissue 
infection,  which  is  as  dangerous.     Enthusiasm  for  the  operation  is  waning  abroad.

Aftpr  raising  the  stump  with  a  vulsellum  forccp.s,  ligatures  replace  the  artery  clamps.     The  uterines  are  secured 
by  special  ligatures.     It  is  wise  to  guard  carefully  against  a  ligature  slipping  while  being  applied.     Most  troublesome 
oozing  would  result. 


My  results  with  present  methods  of  delivery  have  been  so  satisfactory  that  I  have 
felt  no  desire  even  to  try  this  operation,  which,  a  priori,  does  not  appeal  to  me  as  a 
highly  surgical  procedure.  Bumm,  who  uses  it  freely,  admits  that  it  may  not  be 
used  in  suspected  cases,  that  injury  to  the  bladder  may  occur,  that  the  peritoneum  is 
often  opened,  unless  labor  has  been  long  in  progress  and  the  plica  is  retracted;  that 
infection  of  the  connective  tissue  must  be  feared,  and  that  a  large  percentage  of  the 
children  are  lost  in  delivery.  American  operators  have  not  accepted  the  operation, 
and  in  Great  Britain  it  has  been  ix-rformed  only  seven  times.

of  the  mother's  death,  the  child  Hving  longer  if  she  dies  of  apoplexy,  accident, 
hemorrhage,  eclampsia,  or  very  acute  affection  than  if  the  agony  is  prolonged,  as 
in  tuberculosis,  heart  disease,  etc.,  though  in  som'e  of  the  latter  cases  the  vitality 
of  the  child  is  remarkable.     Since  the  mother  uses  up  the  child's  oxygen,  the  latter

A  row  of  sutures,  not  taking  in  the  mucosa,  close.s  the  stump.      In  suspected  septic  cases  this  may  be  omitted  to  favor 

drainage,  just  the  peritoneum  being  closed.

usually  dies  first.  Even  before  Numa  Pompilius,  attempts  to  save  the  child  by 
cesarean  section  after  the  death  of  its  mother  were  made,  but  the  results  were  so 
poor  that  most  men  discountenanced  the  procedure.  In  recent  times  the  operation 
has  often  been  done,  and  the  results  are  more  encouraging.  If  the  pregnancy  has 
advanced  beyond  the  twenty-sixth  week,  no  delay  is  to  be  allowed  after  life  is 
positively  extinct,  but  the  belly  opened  at  once.  It  is  not  even  necessary  legally 
to  obtain  the  consent  of  the  husband  or  the  family,  though  for  his  own  protection 
the  accoucheur  should  get  it  if  possible.  Bacon,  of  Chicago,  in  1911,  proved  this. 
Nor  should  precious  minutes  be  lost  trying  to  hear  the  heart -tones,  because  several 
children  have  been  saved  when  they  were  inaudible.    (See  Rcmy  and  Wyder.) 

The  Talmudists  and  the  Catholic  law  demand  that  cesarean  section  be  per- 
formed on  the  dying  woman  to  save  the  child,  but  this  operation,  painful  to  all 
concerned,  has  rarely  been  done.  If  the  woman's  death  is  only  a  matter  of  a  few 
hours,  this  being  the  opinion  of  a  consultation  of  physicians,  and  the  child  is  living 
and  viable,  the  operation  is  indicated,  but  here,  legally,  it  is  needful  to  get  the  con- 
sent of  the  husband  or  the  next  of  kin.  In  practice  it  may  be  required  to  prepare 
for  the  operation,  and,  awaiting  the  woman's  death,  to  watch  the  heart-tones, 
operating  before  death  only  if  the  child  shows  signs  of  distress.  Naturally,  if  con- 
chtions  are  right  for  a  quick  delivery  from  below,  this  is  preferable.  In  Strassburg, 
a  woman  with  mitral  disease  was  operated  on,  supposedly  in  agony,  but  it  was  only 
catalepsy,  and  she  recovered.

CHAPTER  LXXIII 
MUTILATING  OPERATIONS  ON  THE  CHILD 

Under  this  caption  will  be  considered  the  operations  which  reduce  the  bulk 
of  the  child.  Lessened  in  size,  it  can  be  easier  gotten  through  the  parturient  canal. 
Embryotomy  would  be  a  good  general  term  for  all  the  procedures,  but  it  has  been 
given  a  particular  significance. 

Craniotomy  is  an  operation  which  consists  in  opening  the  fetal  head,  the  evacua- 
tion of  the  brain,  and  extraction  by  means  of  a  large  bone  forceps  or  a  sharp  hook. 

Perforation  is  the  first  step  in  craniotomy,  but  is  sometimes  applied  to  the  whole 
operation. 

Craniodasis  is  the  third  step  in  the  operation,  and  is  also  sometimes  applied 
to  the  whole  operation.  The  instrument,  which  is  nothing  more  nor  less  than  a 
large,  strong,  especially  constructed  bone  forceps,  is  called  a  cranioclast. 

CepJialotrypsis  is  an  operation  in  which  the  head  is  crushed  by  means  of  a 
powerful  forceps  supplied  with  a  compression  screw,  no  perforation  of  the  head  being 
made.  The  instrument  is  called  a  cephalotryptor,  and  was  invented  by  Baude- 
locque,  the  nephew.     It  is  an  obsolete  operation. 

Decapitation  means  what  it  says, — section  of  the  neck, — and  is  accomplished 
either  by  means  of  a  blunt  hook  or  a  sickle-knife,  the  ecraseur,  or  scissors. 

Embryotomy  is  applied  to  decapitation,  to  the  section  of  the  fetal  trunk,  or  to 
the  opening  of  the  body  cavities. 

Exenteration  means  disemboweling  the  fetus  to  diminish  the  size  of  the  trunk. 
It  is  the  same  as  evisceration. 

Brachiotomy  means  section  of  an  arm. 

Cleidotomy  is  an  operation  introduced  bj'  Phenomenoff  in  1895.  It  consists 
of  section  of  the  clavicles,  and  is  used  when  the  shoulders  are  too  broad  to  pass,  the 
head  being  delivered  and  the  cliild  dead. 

Spondylotomy  is  section  of  the  spinal  column. 

Before  forceps  and  version  were  known,  remo^'al  of  the  child  piecemeal  was  the  only  means 
the  ancients  had  of  accomplishing  dehvery  in  cases  of  mechanical  obstruction.  Fig.  893  shows 
some  of  their  crude  instruments.  I'ntil  1830  the  sharp  hook  was  mostly  u-sed  for  extraction,  and 
it  tore  through  the  bladder  and  rectum  as  often  as  it  safely  deUvered  the  head. 

Craniotomy. — Indications — (A)  On  the  Dead  Child. — Xo  accoucheur  should 
have  any  compimctions  about  mutilating  a  dead  child,  yet  I  have  seen  the  most 
atrocious  operations  carried  out  by  physicians  in  order  to  avoid  the  necessity  of 
perforating  a  piece  of  lifeless  clay.  Either  they  fear  opprobrium,  or  they  overrate 
the  dangers  of  craniotomy.  Craniotomy  is  chosen,  the  fetus  being  dead,  when  an 
indication  arises  for  the  immediate  termination  of  labor.  Craniotomy  is  less  danger- 
ous than  the  forceps,  especially  if  the  child  is  large,  the  pelvis  small,  or  the  soft 
parts  unprepared.  It  is  the  rule  for  hydrocephalus.  Sentimental  reasons  advanced 
by  the  family  should  not  stand  in  the  way  of  the  accoucheur's  doing  the  best  for 
the  mother. 

When  the  child  is  surely  dead,  even  if  there  is  no  indication  for  the  immediate 
termination  of  labor,  perforation  of  the  cranium  and  reduction  of  its  size  may  be 
desirable.  This  is  true  of  primiparse — we  wish  to  save  the  levator  ani  and  pelvic 
outlet  from  overstretching,  and,  further,  it  is  thus  possible  to  shorten  the  time  of 
labor.     It  would  perhaps  be  Ijest  in  such  cases  to  perforate  the  cranium,  evacuate

a  large  part  of  the  lirain,  and  leave  the  expulsion  to  nature.  In  private  practice, 
unless  the  family  is  intelligent,  objections  will  be  raised  to  the  disfigurement  of  the 
child,  or  even  its  death  may  be  ascribed  to  the  attendant.  In  delivery  of  the  after- 
coming  head,  the  fetus  having  dietl,  hurry  should  cease,  and  the  head  be  perforated. 
It  is  not  wise  to  delay  too  long,  since  much  blood  may  accumulate  l^ehind  the  head. 
(B)    When  the  child  is  living,  the  indication  for  craniotomy  is  dreadfully  hard

to  place.  Nowhere  in  all  medicine  does  so  heavy  a  responsibility  rest  on  the  medical 
attendant.  He  is  judge,  jury,  and,  perhaps,  executioner  of  an  innocent  baby,  and 
he  can  hardly  be  blamed  if  he  shrinks  from  the  painful  task.  However,  if  he  has 
not  the  moral  courage  to  do  that  which  his  judgment  tells  him  is  the  best  for  the 
mother,  her  family,  and  the  State,  he  should  give  way  to  a  better  man.  It  is 
imperative  to  have  consultation  whenever  the  question  of  craniotomy  on  the  living 


MUTILATING    OPEEATIONS    OX    THE    CHILD  1007 

fetus  arises.     The  decision  will  rest  not  alone  on  scientific  grounds,  as  we  shall  show 
directly. 

In  practice,  craniotomy  will  come  up  for  consideration  in  cases  of  moderately 
contracted  pelves,  in  incorrigible  occipitoposterior  positions,  face  and  brow  pres- 
entations, and  tumors  blocking  the  passage.  Regarding  the  course  of  conduct  of 
contracted  pelves,  the  reader  is  referred  to  the  appropriate  chapter.  The  conditions 
almost  always  met  are  these:  The  woman  has  been  in  labor  many  hours  or  even 
days,  unclean  hands  have  frequently  examined  her,  attempts  at  delivery  with  the 
forceps  have  failed,  the  vulva  is  torn  and  bruised,  the  cervix  hangs  in  shreds,  the 
urine  is  bloody,  the  child  is  injured  or  perhaps  dying.  Here  there  is  only  one  course 
— craniotomy.  The  responsibility  for  the  death  of  the  child  rests  on  those  who  con- 
ducted the  labor  up  to  this  point.  On  the  other  hand,  if  the  woman  is  not  injured, 
not  infected,  and  the  child  is  in  perfect  condition,  one  is  not  justified,  at  least  from 
a  scientific  point  of  view,  in  doing  craniotomy. 

Pinard  and  a  few  Catholic  authors  demand  the  abohtion  of  craniotomy  on  the  lixing  child, 
but  the  overwhelming  majority  of  obstetric  authorities  declares  this  extreme  position  untenable. 
All,  however,  agree  that  the  necessity  for  destrojdng  the  child  is  less  and  less  frequent  as  the 
diagnosis  of  spacial  disproportion  is  earlier  discovered,  giving  a  chance  for  cesarean  section  and 
pubiotomy.  It  follows,  therefore,  that  craniotomy  will  be  more  frequentlj'  performed  in  home 
practice.  In  a  good  maternity  the  necessity  for  sacrificing  the  babe  will  be  of  the  rarest  occur- 
rence. For  centuries  craniotomj-  was  the  opprobrium  of  oljstetric  art.  It  is  tliis  no  longer  in  the 
art,  but  remains  such  in  obstetric  practice. 

Legally,  the  mother  has  a  right  to  demand  that  she  be  exposed  to  no  unusual  danger  for  the 
sake  of  her  child,  and  she  may  refuse  to  do  so  even  at  the  request  of  her  husband.  Also,  she  has  the 
right,  even  if  opposed  by  her  husband,  to  run  added  risk  for  its  sake  if  she  -n-ishes.  The  legal  status 
of  the  unborn  cliild  is  still  unsettled  (Kiernan).  At  present  it  is  part  of  its  mother,  and  has  no 
legal  existence  until  the  cord  is  cut.  The  mother  may  recover  damages  for  its  loss  by  wilful  or 
negUgent  means,  though  itself  it  has  no  redress  if  it  survives  the  injury.  The  moral  and  ethical 
aspects  of  the  question  are  too  broad  to  be  more  than  mentioned  here.  The  stand  of  the  Catholic 
Church  has  been  alluded  to, — "Xon  Decides!" — and  in  such  families  the  attendant  is  guided  bj'  the 
word  of  the  priest,  who  is  always  to  be  summoned.  If  the  accoucheur  is  convinced  that  the  cesa- 
rean section  demanded  would  kill  the  mother,  he  may  retire  from  the  case.  On  the  other  hand,  if 
the  family  insists  on  the  sacrifice  of  the  child,  when  the  accoucheur  feels  that  there  are  good  chances 
for  a  successful  cesarean  section,  he  should  hkewise  decline,  but,  legally,  he  must  stay  by  the  pa- 
tient until  another  ciualified  practitioner  has  assumed  charge. 

Is  consent  of  the  patient  or  next  of  kin  necessarj^?  Legallj',  yes — indeed,  the  attendant 
could  be  held  for  malpractice  if  the  mother  suffered  injury  from  an  operation  less  safe  than  a 
craniotomy,  performed  without  her  consent.  The  facts  of  the  particular  case  are  to  be  laid,  un- 
varnished, before  the  family  for  decision,  which  is  their  right.  Here  much  depends  on  the  abil- 
ity of  the  accoucheur  in  prognosis,  for  he  has  to  evaluate  the  condition  of  the  mother  and  of  the 
babe  and  to  foretell  their  probable  chances  of  life  and  health,  admittedly  a  very  difficult  and  deli- 
cate task.  After  all,  the  family  will  usually  rely  on  the  accoucheur's  judgment,  and  he  will  be 
.immensely  aided  and  comforted  by  adherence  to  the  Golden  Rule. 

In  posterior  occiput  positions  not  amenable  to  the  usual  treatment,  and  where 
the  forceps  fail,  craniotomy  may  be  necessary.  Forced  forceps  deliveries  here,  as 
well  as  in  face  and  brow  presentations  with  the  chin  posterior,  are  equivalent  to 
craniotomies  as  far  as  the  child  is  concerned,  but  have  not  the  saving  grace  of  the 
latter  in  sparing  the  woman  from  serious,  often  fatal,  nmtilations.  Let  no  man  pride 
himself  on  having  accomplished  a  hard  operative  delivery  with  a  whole  but  dead 
child.     Let  him  ask  himself  if  craniotomy  had  not  been  more  humane. 

Craniotomy  is  not  a  good  operation  when  a  tumor  is  impacted  in  the  pelvis. 
Necrosis  of  the  tumor  often  ensues. 

Conditions. — The  pelvis  maj'  not  be  too  contracted.  Barnes  believed  it  pos- 
sible to  deliver  a  mutilated  fetus  through  a  conjugata  vera  of  less  than  two  inches, 
but  most  authors  place  the  limit  at  6.2  cm.  for  flat  and  6.5  cm.  for  generally  con- 
tracted pelves.  Naturally,  these  figures  must  be  raised  if  the  child  is  of  unusual 
size  or  hardness.  The  cervix  must  be  well  dilated  or  easih^  dilatable — the  more  the 
better. 

Technic. — In  addition  to  the  special  instruments  for  craniotomy-,  all  those  used  in  a  forceps 
operation  should  be  boiled.  Naegele's  perforator  (Fig.  S94)  is  one  of  the  best,  but  the  trephine 
makes  a  larger  opening  in  the  skull,  and  the  vagina  is  less  likely  to  be  injured  by  spicute  of  bone,

which  is  also  true  of  the  rubber  ploves  of  tlie  accouclieur  (Fig.  S95).  For  crushing  the  perforated 
head  the  best  instrument  is  Auvarfl's  cranioclast  (Fig.  896).  It  has  three  blades,  and  while  more 
difficult  to  apply  than  the  generally  recommended  Carl  Braun  instrument,  it  does  better  work. 

The  preparations  for  the  operation  are  as  complete  as  usual. 

The  head  is  steadied  by  an  assistant  from  the  outside,  or  seized  I)}'  means  of  a

strong  vulsellum  forceps  sunk  into  the  scalp.  In  some  cases  I  hold  it  with  the 
obstetric  forceps.  Under  cover  of  the  whole  hand  the  perforator  is  introduced  and 
applied  to  the  most  accessible  portion  of  the  head,  care  being  taken  that  it  does  not 
glance  off,  which  advice  is  to  be  specially  heeded  when  the  cutting  perforator  is

used  (Fig.  898).  It  is  also  possible  to  expose  the  head  by  specula  and  do  the  opera- 
tion by  sight.  After  the  opening  is  made,  one  finger  is  hooked  into  it,  then  the  brain 
matter  is  thoroughly  broken  up  by  means  of  a  long  forceps,  taking  special  care  to 
tear  the  tentorium  and  destroy  the  medulla,  this  to  avoid  the  painful  experience  of

seeing  the  child  gasp  after  delivery.  Two  cases  are  recorded  where  the  child  lived 
a  while  in  spite  of  the  mutilation.  Now  the  cranium  is  washed  out  with  a  stream 
of  sterilized  water.  The  third  step  of  the  operation  is  crushing  th(>  emptj^  skull. 
Under  the  same  rules  as  those  of  forceps  one  outer  blade  of  the  cranioclast  is  laid 
over  the  face  of  the  child,  and  while  this  is  held  by  an  assistant,  the  solid  blade  is

pushed  into  the  skull  to  the  base.  By  means  of  the  compression  screw  the  two  are 
brought  slowly  together,  hut  after  they  are  locked  and  before  they  are  tightened  the 
accoucheur  should  assure  himself  that  nothing  is  caught  in  the  grasp  of  the  jaws.  When 
the  handles  are  in  contact,  the  two  are  locked  with  the  hasp,  then  the  third  blade 
applied  and  also  screwed  down  tight.  The  fourth  act — extraction — is  done  with 
the  same  care  and  gentleness  as  the  forceps  operation,  and  the  proper  mechanism 
of  labor  should  be  followed.  There  is  no  occasion  for  hurry.  Frequent  examina- 
tions are  made  to  determine  if  the  head  is  following,  to  preserve  the  parts  from  injury 
by  spiculse  of  bone,  which  may  be  sharp  and  piercing,  and  to  aid  in  stripping  the 
cervix  back  over  the  head.  If  the  instrument  is  well  applied,  it  will  not  slip  off; 
if  it  does,  it  is  to  be  reapplied,  and  higher  up,  grasping  the  face.  Spiculse  or  sharp 
edges  of  bone  are  removed  by  means  of  the  ^Nlesnard-Stein  l)one  forceps  (Fig.  899).

The  same  instruments  as  for  forceps,  plus  the  destructive  instruments. 


The  perineum  is  to  be  preserved  b}'  slow  delivery — at  least,  the  woman  should  be 
spared  injury  of  this  structure. 

In  many  cases,  after  the  head  is  delivered,  the  shoulders  are  arrested.  It  is 
not  prudent  to  use  force.  The  size  of  the  shoulder-girdle  is  reduced  by  the  operation 
of  cleidotomy.  One  hand  searches  for  the  more  accessible  of  the  two  clavicles,  and 
under  the  guidance  of  this  hand  the  tip  of  the  decapitation  scissors  is  passed  to  a 
point  on  the  neck  of  the  child  adjacent  to  it.  With  tiny  snipping  motions  the  points 
of  the  scissors  are  pushed  under  the  skin  of  the  neck,  and,  guided  by  the  fingers,  a 
clavicle  is  reached  and  cut.  The  other  is  treated  the  same  way.  It  is  now  possible 
to  deliver  the  trunk  of  the  child.  In  very  exceptional  cases  the  sternum  must  be 
bisected  and  the  chest  emptied — this  in  cases  of  monsters  or  anasarca.  If  delivery 
of  the  trunk  still  causes  difficultv,  one  arm  may  be  brought  dowTi  and  traction  made

on  it,  or,  better,  the  blunt  hook  is  passed  into  the  axilla  and  combined  traction  made 
on  it  and  the  head. 

If  the  craniotomy  is  performed  in  face  presentation,  the  perforation  is  made

ble side  of  the  head.     Naegclc's  perforator  is  the  best  here,  and  a  large  opening  is

to  be  obtained.     Thorough  evacuation  of  the  brain  by  irrigation  is  essential,  and  it 
usually  is  not  necessary  to  crush  the  skull,  slow  traction  causing  it  to  collapse. 

It  is  not  wise  to  cut  the  body  off  the  head  under  the  notion  that  thus  the  latter

will  be  more  accessible.  One  loses  a  good  handle  on  the  head.  If  this  accident  has 
happened,  the  floating  head  may  be  steadied  with  a  strong  vulsellum  forceps,  then 
firmly  seized  with  a  pair  of  obstetric  forceps,  perforated  with  a  trephine,  crushed 
with  a  cranioclast,  and  extracted.     If  the  pains  are  strong  and  the  accoucheur  is

certain  that  blood  is  not  accumulating  in  the  uterus,  the  delivery  of  the  head  may 
be  left  to  nature.     I  usually  do  not  wait. 

In  all  cases  as  soon  as  the  mouth  of  the  child  is  accessible  the  throat  is  to  be 
stuffed  full  of  wet  cotton,  because  sometimes  the  elasticity  of  the  chest  causes  the

evidence  of  life.  After  craniotomy,  a  hot  uterovaginal  douche  of  sterile  water  is 
given  and  it  is  my  custom  to  tampon  the  uterus  lightly. 

Decapitation. — Hippocrates  did  decapitations,  using  a  curved  knife.     It  is

MUTILATING    OPERATIONS    ON   THE    CHILD  1013 

the  rarest  of  all  operations,  nowadays,  owing  to  the  general  improvement  of  olistetric 
practice.  Neglected  transverse  presentation  is  the  usual  indication,  but  sometimes 
it  is  needed  to  decapitate  the  first  of  interlocked  twins,  and,  still  more  rarely,  in 
the  treatment  of  double  monsters.  The  conditions  for  the  operation  are  the  same 
as  for  craniotomy,  and  the  same  question  will  arise  as  to  the  propriety  of  performing 
it  when  the  child  lives.  In  neglected  transverse  presentations,  however,  it  is  most 
exceptional  for  the  child  to  be  found  alive.  Of  prime  importance  in  these  cases 
is  an  accurate  knowledge  of  the  state  of  the  uterus.  If  the  lower  uterine  segment  is 
excessively  thinned,  indeed,  on  the  point  of  rupturing,  decapitation  should  be 
superseded  by  evisceration,  because  this  operation  will  not  increase  the  distention — 
rather  the  opposite.  If  the  shoulder  is  wedged  deeply  into  the  excavation,  the  neck 
being  stretched  almost  parallel  with  the  long  axis  of  the  fetal  body,  evisceration  is  a 
better  operation.  If  the  neck  is  readily  accessible  and  the  uterus  not  dangerously 
thinned,  decapitation  is  a  very  satisfactory  operation.  Fig.  900  shows  some  of  the 
instruments  used  for  severing  the  neck.  Carl  Braun's  hook  has  been  modified  by 
Jardine  by  making  the  inside  somewhat  sharp — an  improvement.  I  have  usually 
performed  the  operation  as  here  described,  all  under  the  guidance  of  the  hand,  but 
I  can  see  advantages  in  doing  it  with  the  aid  of  sight,  the  field  being  exposed  by 
broad  specula  and  the  neck  being  pulled  down  with  the  hook  or  powerful  vulsella. 

First  Act. — To  make  the  neck  more  readily  reached,  traction  i.s  put  on  the  arm.  Passing 
the  whole  hand  into  the  vagina,  the  neck  is  encircled  by  two  fingers  and  the  thumb.  Guided  by 
the  latter,  the  hook  is  passed  over  the  neck,  where  it  is  firmly  pulled  into  the  soft  parts.  No 
attempt  to  tu-ist  should  be  made  until  the  hook  is  well  placed  and  the  fingers  are  apposed  to  the 
thumb,  thus  encirchng  the  neck  and  guarding  the  mother's  tissues  from  injury.  Now  the  handle 
is  twisted,  slowly  pulling  at  the  same  time,  turning  the  knob  in  the  direction  of  the  head.  The 
first  half-turn  breaks  the  cervical  spine,  after  which  the  hook  takes  a  deeper  hold  on  the  muscles, 
and  a  full  turn  severs  these.  The  skin  now  remains,  and  this  is  packed  into  the  hook  by  means  of 
the  fingers,  and  a  few  complete  turns  cut  it  with  the  cleanness  of  a  knife.  Sometimes  a  few  tough 
shreds  must  be  severed  with  the  scissors  (Fig.  901). 

Second  Act. — Extraction  of  the  trunk  is  made  on  the  prolapsed  arm;  only  rarely  is  it  neces- 
sary to  open  the  chest  or  apply  the  hook  to  the  trunk.  The  neck  must  be  covered  by  the  fingers 
during  delivery  to  protect  the  vagina  from  being  pierced  by  spicula?  of  bone. 

Third  Act. — Delivery  of  the  head  is  accompHshed  by  expression  from  above,  traction  on  the 
jaw  from  below,  or,  if  need  be,  by  forceps  or  even  craniotomy.  In  the  latter  instance  the  head 
must  be  firmly  fixed  either  by  the  forceps  or  by  strong  vulsella.  Sharp  projections  of  bone  may 
do  much  damage  if  unobserved. 

Evisceration. — In  cases  of  arrested  delivery  of  the  child,  in  complicatio  corpore 
(see  p.  618),  the  neck  is  inaccessible  to  the  hook  or  the  scissors.  Exenteration  is 
the  best  operation.  A  large  hole  is  made  in  the  chest  with  the  scissors,  several 
ribs  being  resected.  With  the  fingers  the  entrails  are  pulled  out — first  out  of  the 
chest,  then,  after  boring  through  the  diaphragm,  out  of  the  abdomen.  Usually 
the  body  collapses,  and  the  child  can  be  easily  extracted,  but  if  there  is  the  least 
resistance,  the  spinal  column  should  be  cut  through  with  the  scissors  (spondylotomy), 
a  perfectly  safe  procedure,  since  the  instrument  operates  inside  the  body  of  the  child, 
the  maternal  soft  parts  being  protected.  Now  the  extraction  may  be  made  by 
pulling  on  the  arm  or  pulling  do^^^l  the  feet  of  the  child,  or  by  hooking  the  blunt 
hook  over  the  spinal  column.

CHAPTER  LXXIV 
INDUCTION  OF  PREMATURE  LABOR 

This  means  the  artificial  interruption  of  pregnancy,  after  the  child  has  become 
viable,  but  before  term.  Louise  Bourgoise,  midwife  to  Mary  of  Medici,  in  1608 
introduced  the  operation  of  inducing  labor  prematurely  as  a  therapeutic  measure. 
In  1756  Denman  reported  20  cases  of  induced  premature  labor  for  contracted  pelvis. 
In  all  probability,  according  to  Kleinwilchter,  the  ancient  Greeks  performed  abor- 
tion for  the  same  reason.     Soranus  of  Ephesus,  in  the  second  century,  mentions  it. 

Indications. — There  is  hardly  any  condition  affecting  the  pregnant  woman  that 
may  not  give  the  indication  for  emptying  the  uterus.  The  most  common  are — ■ 
first,  contracted  pelvis,  the  idea  being  that  a  small  fetus  will  pass  through  easily; 
and,  second,  diseases  which  affect  the  health  of  the  woman  so  deeply  that  it  is  feared 
she  will  not  survive  until  term,  or  that  the  inroads  on  her  constitution  will  be  such 
as  materially  to  shorten  her  life.  The  indications  may  be  grouped  under  five 
headings:  1.  Contracted  pelvis.  2.  Diseases  which  are  incidental  to  pregnancy. 
3.  Diseases  accidental  to  pregnancy.  4.  Habitual  death  of  the  fetus  after  viability, 
but  before  term.     5.    Prolonged  pregnancy  and  overgrowth  of  the  child. 

For  contracted  pelvis  see  p.  713.  Under  diseases  incidental  to  pregnancy  see  the 
chapters  on  Eclampsia,  Toxemia,  Chorea,  Pernicious  Vomiting,  Pernicious  Anemia, 
Placenta  Praevia,  Abruptio  Placentae,  Psychoses,  Multiple  Neuritis,  Impetigo 
Herpetiformis,  Polyhydramnion,  Hydatidiform  Mole,  etc.  The  keynote  of  the 
treatment  is  to  stop  the  gestation  at  a  point  before  either  mother  or  child,  or  both, 
are  in  danger,  either  to  life  or  to  health. 

Under  diseases  accidental  to  pregnancy  see  the  chapters  on  Bright's  Disease, 
Tuberculosis,  especially  of  larynx.  Heart  Disease,  Diabetes,  Retinitis,  Psychoses. 

A  very  interesting  condition  is  the  habitual  death  of  the  child  after  viability, 
but  before  term.  In  apparently  healthy  women  successive  children  die,  either 
just  before  labor  or  directly  after.  The  causes  are  mostly  unknown.  Syphilis  is 
the  most  common,  and  my  practice  is,  even  if  no  history  of  the  same  is  forthcoming, 
and  even  if  the  seroreaction  of  both  parents  is  negative,  to  submit  both  to  a  mild 
mercurial  treatment.  An  occasional  success  has  encouraged  me  to  continue  this 
plan.  Bright'sdisease  in  a  latent  form  explains  a  few  cases,  anemiaand  constitutional 
disorders,  diabetes,  adiposity,  and  hypothyroidism  a  few  more.  Often  enough  no 
cause  can  be  found.  Without  doubt  the  husband  is  sometimes  to  blame,  and  I 
am  convinced  that  some  men  cannot  produce  a  spermatozoid  capable  of  giving  the 
normal  ovum  sufficient  life  impetus  to  carry  it  through  a  full  gestation.  This  has 
been  observed  in  alcoholism,  lead-poisoning,  in  tobacco-workers,  x-ray  operators, 
and  even  without  apparent  reason.  The  treatment  of  such  cases  is  causal,  and  in 
addition  to  this  good  results  have  been  observed  in  a  complete  reversal  of  the  usual 
mode  of  life.  For  example,  a  man  overloaded  with  business  cares  may  be  sent,  with 
his  wife,  to  spend  six  months  in  camp  on  the  plains  or  in  the  mountains. 

If  the  exact  time  when  the  children  usually  die  is  known,  labor  may  1)0  brought 
on  a  few  weeks  before  this.  In  some  of  these  cases  ev(Ty  alternate  child  dies,  or 
the  habit  is  broken  up  from  some  cause  or  other.  It  will  be  noticed  that  this  indica- 
tion is  precarious,  but  most  authors  allow  it. 

Prolonged  Pregnancy  and  Overgrowth  of  the  Child. — Some  women  habitually 
go  over  the  usual  period  of  pregnancy,  and  not  seldom  the  child  dies  or  suffers  so 

1014 


INDUCTION    OF    PREMATURE    LABOR  1015 

much  during  delivery  that  it  succumbs  shortly  after.  In  these  cases  the  cranium 
is  usually  hard  and  angular,  the  bones  stiff  and  unmoldable,  the  flesh  firm  and  un- 
pliable,  and  the  body-length  increased.  In  some  instances  the  child  as  a  whole  is 
of  greater  size  than  ordinarily,  and  the  mechanical  labor  difficulties  are  pronounced. 
I  have  already  (p.  636)  discussed  this  subject,  and  stated  that  my  practice  is  not  to 
allow  the  women  to  go  too  far  beyond  term.  Some  women  come  to  the  accoucheur 
giving  a  history  of  difficult  labors  with  immense  children.  It  is  wise  to  accept  the 
story  with  much  reservation,  because  often,  for  various  reasons,  the  previous 
attendant  will  exaggerate  the  size  of  the  child,  and  again  the  patient  herself  will  do 
the  same,  sometimes  forgetting.  Nevertheless,  such  a  pregnancy  requires  watching, 
and  if  the  child  actually  does  grow  too  large,  it  is  best  to  interrupt  it. 

Conditions. — The  child  must  be  living  and  viable  in  all  cases  where  the  preg- 
nancy is  terminated  in  its  interests.  It  may  not  be  deformed.  A  child  delivered 
before  the  thirtieth  week  of  gestation  has  but  little  chance  of  survival.  Speaking 
broadly,  with  every  week  of  gestation  after  this  period  the  child's  chances  improve 
10  per  cent.  In  determining  the  size  of  the  child  by  palpation  the  possibility  of 
twins  is  to  be  borne  in  mind. 

The  pelvis  may  not  be  too  markedly  contracted,  it  being  generally  conceded 
that  in  pelves  below  7  and  l}/2  cm.  the  outlook  for  an  infant,  even  at  the  thirty- 
second  week,  is  dubious. 

The  condition  of  the  mother  must  be  such  that  she  will  probably  live  through 
the  operation.  Although  several  cases  are  on  record  of  the  operation  being  done 
on  a  moribund  woman,  actual  practice  seldom  justifies  it.  The  consent  of  the 
mother  or  next  of  kin  must  be  obtained,  and  in  all  cases  a  consultation  is  essential, 
first,  because  human  judgment  is  fallible,  and,  second,  to  avoid  legal  entanglements 
later.     A  written  statement  is  desirable. 

The  Prognosis. — In  a  collection  of  2200  cases  Sarwey  found  a  maternal  mor- 
tality of  1.4  per  cent. — 0.6  per  cent,  due  to  infection,  but  part  of  this  may  have  been 
due  to  causes  not  inherent  in  the  operation  itself.  Nowadays,  Avith  our  perfected 
technic,  the  induction  of  labor  should  be  without  mortality  ascribable  to  infection 
carried  in  by  the  accoucheur,  but  it  is  not  possible  always  to  avoid  infecting  the 
woman  with  virulent  bacteria  already  present  in  the  genitalia,  for  example,  in 
gonorrhea,  in  the  urine  from  a  ureteropyelitis,  even  those  of  the  ordinary  vaginal 
flora.  If,  as  not  seldom  happens,  the  operation  requires  repeated  internal  manipu- 
lations extending  over  several  days,  the  streptococci  in  the  vagina,  given  blood, 
bruised  tissue,  and  a  depressed  woman,  acc^uire  invasive  virulence;  therefore  it  is 
not  uncommon  in  prolonged  cases,  in  spite  of  the  most  painstaking  aseptic  technic, 
for  the  patient  to  have  fever,  and  in  a  few  cases  fatal  sepsis  may  arise. 

The  morbidity  is  not  small.  Dilatation  of  the  cervix  is  usually  imperfect 
and  lacerations  are  common,  which  is  also  true  of  the  pelvic  floor  to  a  less  degree. 
Operative  termination  of  the  labor  is  oftener  required,  which  carries  "wdth  it  the 
dangers  so  often  referred  to.  If  the  uterus  is  very  sluggish,  the  various  operations 
have  to  be  repeated  day  after  day.  Such  cases  act  badly  on  the  nervous  system  of 
the  patient.  In  a  few  cases  on  record  the  attempt  to  get  the  uterus  to  act  had  to 
be  abandoned,  and  the  pregnancy  went  to  term.  Some  of  the  methods  employed 
are  not  without  danger — the  insertion  of  a  bougie,  for  instance,  may  detach  the 
placenta. 

For  the  child,  the  general  mortality  is  from  30  to  60  per  cent.,  depending  on  the 
period  of  pregnancy  and  the  indication  which  demanded  the  interference.  The 
child  of  a  sickly  mother  will  have  less  chance  of  survival  than  one  from  a  healthy 
parent.  The  dangers  besetting  the  child  in  passing  a  narrowed  pelvis  are  to  be 
carefully  weighed.  Nowadays,  specialized  obstetric  nursing  and  the  scientific 
incubator  have  done  much  for  the  premature  infant.  The  presentation  of  the  child 
has  much  to  do  with  the  prognosis,  that  of  the  breech  being  particularly  unfavorable. 


1016  OPERATIVE    OBSTETRICS 

It  is  best  to  secure  cephalic  presentation  l)c'fore  operating — at  least,  perfect  dilata- 
tion of  the  parturient  canal — to  make  the  exit  of  the  tender  child  the  easiest  possible. 

Technic. — Of  the  20  or  more  methods  that  liave  been  recommended,  only  a  few 
are  practised,  and  the  selection  will  depend  on  the  urgency  of  the  case,  the  rapidity 
with  which  it  is  necessary  to  empty  the  uterus,  and  individual  preference. 

Puncture  of  the  Bag  of  Waters.— Thh  is  the  oldest  method,  mentioned  by 
Demnan  in  1756,  as  the  generally  known,  probably  only,  one.  Anj^  long-pointed 
instrument  may  be  used,  as  a  scissors,  but  where  obtainable,  a  thin  trocar  is  better. 
By  forcmg  the  head  down  into  the  cervix,  by  allowing  the  water  to  trickle  away, 
not  to  rush  out  in  a  stream,  perhaps  using  the  Sims'  position,  prolapse  of  the  cord 
may  be  prevented.  If  the  head  is  movable  and  prolapse  of  the  cord  likely,  it  is 
better  to  substitute  another  method.  In  primiparae,  with  a  closed  cervix,  the  dis- 
advantages of  a  dry  labor  are  to  be  borne  in  mind.  Puncture  of  the  membranes  is 
the  most  certain  of  all  methods,  and  may  be  used  when  older,  milder  means  fail. 

Bougies. — Krause,  in  1855,  introduced  one  or  two  elastic  solid  bougies  into 
the  uterus  between  the  membranes  and  the  wall.  Though  the  method  is  quite 
popular,  I  hardly  ever  use  it,  finding  it  inefficient  (the  pains  seldom  come  on  within 
forty-eight  hours)  and  somewhat  dangerous.  In  two  cases  of  my  owti  the  placenta 
was  encroached  on,  with  severe  but  controllable  hemorrhage.  The  bag  of  waters 
may  be  punctured,  and  I  think  the  danger  of  infection  is  higher  than  with  other 
methods.  In  a  case  seen  in  Berlin  necrosis  of  the  track  of  the  bougies  was  found 
postmortem. 

By  the  light  of  broad  specula  the  cervix  is  exposed,  and  two  No.  24  French  size, 
soft -rubber  bougies  passed  into  the  uterus,  going  to  either  side,  behind,  in  the  direc- 
tion of  the  least  resistance.  If  the  least  blood  appears,  both  are  to  be  removed  and 
the  vagina  packed.  Next  day  another  method  of  induction,  usually  puncture  of 
the  membranes,  is  to  be  practised. 

Dilatation  of  the  Cervix.- — Hydrostatic  dilatation  of  the  cervix  is  often  used  to 
hasten  labor  and  in  the  treatment  of  placenta  prsevia.  A  bag  in  the  cervix  both 
dilates  it  and  stimulates  the  pains.  The  technics  have  already  been  described. 
When  the  bags  are  used  simply  to  start  labor  pains,  the  small-sized  ones  are  selected. 
Pains  usually  come  on  within  six  hours,  but  often  subside  immediately  the  bag  is 
expelled,  requiring  the  insertion  of  another.  Sometimes  the  pains  do  not  come  on 
for  several  days,  even  if  larger  and  larger  bags  are  put  in  ever}^  twenty-four  hours. 
It  cannot  be  denied  that  sometimes  the  bag  displaces  the  head  and  allows  mal- 
presentations  and  prolapse  of  the  cord  to  occur. 

Packing  the  cervix  and  low^er  uterine  segment  with  gauze  is  a  favorite  method 
of  the  author.  It  is  illustrated  in  Fig.  792.  Under  the  guidance  of  the  fingers, 
or  in  the  view  provided  by  broad  specula,  and  with  the  cervix  drawn  down  by 
vulsellum  forceps,  a  strip  of  gauze  three  to  five  yards  long  and  three  inches  wide  is 
snugly  and  evenly  placed  in  the  lower  part  of  the  uterus  and  the  cervical  canal. 

Sometimes  the  separation  of  the  membranes,  by  swinging  the  finger  around  the 
lower  pole  of  the  uterus,  is  enough  to  bring  on  contractions  (Hamilton).  I  have 
used  this  method  at  term  with  labor  imminent. 

Only  exceptionally  are  we  required  to  use  great  haste,  as  in  eclampsia,  threaten- 
ing edema  of  the  lungs  from  heart  or  lung  disease,  and  in  such  instances  vaginal 
cesarean  section  is  the  method  of  choice,  though  occasionally  the  aljdominal  route 
is  to  be  selected. 

In  cases  of  sufficient  urgency,  but  less  than  the  last,  puncture  of  the  membranes 
and  the  insertion  of  a  balloon  dilator  will  be  the  methods  of  choice,  followed  later 
by  manual  dilatation  of  the  cervix  and  delivery. 

Where  there  is  no  great  hurry,  my  practice  is  as  follows:  The  patient  is  pre- 
pared as  for  any  major  obstetric  operation.  Under  the  strictest  aseptic  jirecautions 
the  cervix  is  dilated  with  the  finger-tip  and  straightened,  then  the  region  just  above 


INDUCTION    OF    PREMATURE    LABOR  1017 

the  internal  os  is  loosely,  and  the  cervical  canal  tightly,  packed  with  gauze,  as 
described  on  p.  908,  leaving  no  ends  hanging  out  the  vulva.  I  usually  do  this 
about  5  P.M.  The  patient  is  allowed  a  light  supper,  and  one  hour  after  this  a  single 
dose  of  castor  oil  is  administered.  Pains  usually  come  on  by  3  or  5  o'clock  the 
next  morning,  and  as  soon  as  they  are  well  estal)lished,  the  gauze  may  be  removed. 
If  pains  do  not  come  on  by  5  p.m.  the  next  evening,  the  same  procedure  is  re- 
peated, or  a  medium-sized  Voorhees  bag  is  inserted.  While  the  uterus  may  not 
have  gotten  into  regular  action,  some  pains  always  have  occurred,  and  they  have 
softened  the  cervix  and  produced  some  effacement.  If,  next  morning,  regular  pains 
have  not  set  in,  the  membranes  are  ruptured,  and  now,  with  very  few  exceptions, 
the  labor  goes  on  quickly.  I  am  using  pituitrin  in  5  and  10  minim  doses  to  aid  the 
uterine  action,  with  fair  success. 

Irregular  uterii  j  action,  abnormal  contraction  rings,  malpresentations  and  mal- 
positions of  the  fetus,  insufficient  dilatation  of  the  cervix,  nervous  exhaustion,  sleep- 
lessness, prolonged  anxiety  of  the  patient,  fever,  prolapse  of  the  cord,  lacerations 
of  the  soft  parts,  operative  interference,  postpartum  hemorrhage,  and  many  other 
grave  and  less  grave  complications  must  be  expected  when  you  induce  labor. 

Premature  children  suffer  severely  from  the  traumatism  of  labor.  Breech  de- 
liveries are  especially  fatal  to  them,  therefore  version,  as  a  rule,  is  contraindicated. 
They  are  especially  prone  to  fracture  of  the  bones,  cerebral  hemorrhage,  and  ate- 
lectasis pulmonum. 

If  delivery  is  effected  l)y  forceps,  episiotomy  is  desirable  to  spare  the  head  the 
perineal  pressure.  After  delivery  it  is  essential  that  the  lungs  be  well  inflated,  that 
the  infant  be  kept  warm,  and  that  it  be  placed  in  a  properly  ventilated  and  disin- 
fected incubator.  ^Mother's  milk  and  good  nursing,  however,  are  more  important 
than  the  incubator.     The  best  results  are  obtained  by  combining  the  three. 

For  the  sake  of  completion  a  few  obsolete  and  dangerous  methods  may  be 
named:  Puncture  of  the  membranes  high  up  in  the  uterus  with  a  trocar;  intra- 
uterine injection  of  water,  hot  and  cold,  of  gh'cerin,  milk,  etc.;  the  Kiwisch  douche 
— a  stream  of  hot  water  against  the  cervix;  carbon  dioxid  w-ater  irrigations  of  the 
vagina;  vaginal  tamponade;  colpeurj-sis;  electricity;  the  a:-ray;  irritation  of  the 
nipples;  medicines,  as  quinin,  cimicifuga,  ergot,  cathartics,  etc.  (Literature  in 
Williamson,  Jour.  Obst.  and  Clyn.,  Brit.  Empire,  August,  1905,  p.  254.) 

Following  a  suggestion  of  Heide,  Rong}^  injects  fetal  blood-serum  for  the  in- 
duction of  labor  with  good  results  (Amer.  Jour.  Obstet.,  July,  1912). 

Induction  of  Abortion. — This  operation  has  been  done  since  remotest  anti- 
quity, and  in  savage  as  well  as  civilized  lands.  By  some  it  was  done  to  prevent 
overpopulation,  and  was  a  recognized  procedure;  b}'  others  to  avoid  the  discomforts 
and  dangers  of  the  function  of  reproduction,  or  even  the  disfigurement  of  the  person 
wrought  by  gestation,  as  in  decadent  Rome,  The  child  was  considered  to  be  with- 
out a  soul — only  a  gro"wi;h  on  its  mother.  As  a  therapeutic  measure,  abortion  was 
done  long  before  Christ;  indeed,  the  production  of  abortion  by  a  physician  for 
other  reasons  was  considered  unethical,  as  witness  the  oath  of  Hippocrates.  The 
ancient  Jews  considered  abortion  a  great  sin,  but  admitted  it  as  a  means  of  cure  of  dis- 
ease affecting  the  mother.  The  promulgation  of  Christian  principles  did  much  to 
stop  the  practice,  at  least  openly,  and  soon  the  law  made  it  a  punishable  offense. 
(See  Lecky,  Historj-  of  European  Morals.) 

One  of  the  saddest  commentaries  on  our  modern  ''civilization,"  in  a  so- 
called  religious  and  ethical  era,  is  the  prevalence  of  criminal  abortion.  A  young 
physician  is  not  long  in  practice  before  he  is  approached,  in  a  hundred  ways,  open 
or  concealed,  to  perform  a  criminal  abortion.  Xot  alone  the  single  woman,  but 
the  married,  will  come.  All  arguments  will  be  brought  to  bear — that  of  friend- 
ship for  a  stricken  family',  the  disgrace  of  a  child  under  untoward  circumstances, 
the  impossibility  of  caring  for  a  large  number  of  children,  ill  health,  even  gold  will  be 


1018  OPERATIVE    OBSTETRICS 

offered.  The  physician  should  ahow  none  of  these  things  to  influence  him  to  do  an 
abortion,  because,  first,  it  is  murder,  and  conscience  will  make  his  later  days  mis- 
erable; second,  it  is  a  criminal  offense,  and,  performed  in  the  way  most  of  such 
operations  have  to  be  done,  infection  will  likely  follow,  and  perhaps  death  of  the 
patient,  with  a  prison  term  for  the  perpetrator,  in  the  perspective;  third,  acci- 
dents, like  perforation  of  the  uterus  and  anesthetic  deaths,  are  not  uncom- 
mon; fourth,  if  he  does  it  once  he  is  a  lost  man;  the  woman,  no  matter  how 
firmly  she  has  been  bound  to  secrecy,  will  tell  her  friends,  and  soon  his  reputation 
as  an  abortionist  will  be  established.  There  are  other  reasons,  but  the  conscientious 
physician  will  not  need  any  at  all.  A  word  of  warning:  Let  the  inexperienced 
physician  beware  of  simulated  disease.  A  woman  will  read  up  on  some  disease 
which  she  knows  sometimes  gives  the  indication  for  abortion,  and  will  try  to  impress 
the  doctor  that  she  is  deathly  ill. 

Therapeutic  abortion  is  rarely  indicated,  and  lately  our  general  therapy  has 
improved  so  much  that  few  affections  justify  its  performance.  (1)  Contracted 
pelvis  with  a  conjugata  vera  below  6  cm.,  mentioned  by  Soranus  of  Ephesus  in  the 
second  century  a.d.,  and  by  Cooper  in  1772,  to  avoid  the  terrific  mortality  of 
cesarean  section.  Nowadays,  with  the  safety  of  cesarean  section,  the  accoucheur 
should  refuse  to  perform  abortion  for  this  indication  unless  there  are  other,  scienti- 
fic reasons,  e.  g.,  heart,  lung,  or  kidney  disease.  (2)  Hyperemesis  gravidarum 
and  other  forms  of  toxemia.  Without  doubt,  here  is  a  real  indication  for  abortion, 
but  a  restricted  one.  In  cases  of  toxemic  vomiting,  with  the  evidences  of  real  in- 
volvement of  the  structure  of  the  liver  and  kidneys,  one  should  not  wait  too  long 
before  emptying  the  uterus.  (See  Hyperemesis.)  (3)  Incarceration  of  the  retro- 
flexed  gravid  uterus  is  usually  better  treated  by  laparotomy.  (4)  Advancing 
tuberculosis,  as  shown  by  loss  of  weight,  evening  fever,  hemoptysis,  etc.  Most 
authorities  believe  that  the  progress,  while  not  always  stayed,  is  rendered  less 
fulminant  by  interrupting  pregnancy.  A  combination  of  hyperemesis  gravidarum 
and  tuberculosis  is  a  positive  indication  for  abortion,  as  also  is  tubercular  laryngitis. 
(5)  Heart  disease  is  only  an  indication  when  the  muscle  is  badly  inefficient,  as  ad- 
vanced myocarditis  and  discompensation.  (6)  Diabetes  and  other  constitutional 
diseases,  as  under  induced  labor.  (7)  Diseases  of  the  kidneys,  especially  if  com- 
plicated by  retinitis.  (8)  Other  diseases  which  seriously  jeopardize  the  mother,  as 
Basedow's  disease,  leukemia,  pernicious  anemia,  chorea,  etc.  (9)  Diseases  of  the 
ovum — polyhydramnion,  hydatidiform  mole,  death.  In  the  last-mentioned,  hemor- 
rhage from  the  uterus  usually  indicates  interference,  and  then  the  procedure  cannot 
be  called  true  abortion;  rather  we  are  simply  completing  a  process  nature  has 
begun.  Hemorrhage  during  the  early  months  of  pregnancy  may  come  from  pla- 
centa prsevia,  placenta  marginata,  cornual  placenta,  and  chronic  abortion,  and 
may  require  interference.  Repeated  bleedings  are  almost  always  followed  by 
complete  abortion.  Sometimes  the  pregnancy  continues  to  term,  and  trouble 
arises  in  the  placental  stage  from  placenta  accreta  and  postpartum  hemorrhage. 
Again,  a  placenta  prsevia  will  show  itself  in  the  seventh  or  eighth  month.  While 
a  few  of  my  cases  have  gone  to  term — as  a  rule,  I  regard  frequent  hemorrhages  in  the 
early  months  sufficient  indication  for  therapeutic  abortion. 

In  one  case,  a  neurotic,  highly  bred,  "overcivilized"  (Reynolds)  woman,  the 
psychic  shock  of  the  pregnancy  was  so  great  that  the  question  of  therapeutic  abor- 
tion was  seriously  considered.  I  refused  to  do  it,  advising  mental  treatment,  and 
the  woman  disappeared,  but  had  she  not,  in  my  hands,  quickly  recovered  from  the 
continuous  nervous  excitement,  the  sleeplessness,  the  almost  maniacal  fear  of  preg- 
nancy, which  reminded  me  very  much  of  the  overwhelming  terror  some  peoj^le  have 
of  thunder-storms,  I  am  sure  that  abortion  would  have  been  justified. 

The  conditions  for  the  operation  are  about  the  same  as  for  induced  labor.  Al- 
ways insist  on  a  consultation,  draw  up  a  written  statement  of  the  facts  in  the  case, 


INDUCTION    OF    PREMATURE    LABOR  1019 

and  have  it  signed  b}-  the  woman,  her  next  of  kin,  and  all  the  physicians  in  charge. 
Every  appearance  of  mystery  and  secrecy  must  be  sedulously  avoided.  It  is  best 
to  perform  the  operation  in  a  hospital. 

Technic. — The  operations  may  be  divided  into  those  done  during  the  first  eight  weeks,  those 
done  from  the  eighth  to  the  sixteenth  week,  and  those  from  this  time  until  the  cliild  is  \-iable. 

In  the  first  eight  weeks  the  uterus  usually  can  be  emptied  all  at  one  sitting.  An  anesthetic 
is  not  always  required,  but  the  accoucheur  must  be  able  to  do  everything  with  the  greatest  delibera- 
tion and  comfort.  A  careful  bimanual  examination  is  made  to  discover  an  ectopic  pregnancy  or 
a  retroflexion.  The  cervix  is  dilated  with  Goodell  dilators  of  increasing  sizes,  this  part  requiring 
from  fifteen  to  twentj^-five  minutes.  Then  the  contents  of  the  uterus  are  removed  with  the  curet 
and  polj^pus  forceps,  after  which  the  cavity  is  lightly  filled  with  a  strip  of  gauze.  This  stops  the 
bleeding,  and  when,  next  day,  it  is  removed,  it  brings  with  it  shreds  of  decidua  which  may  have 
been  overlooked.  In  rare  cases  the  cervix  is  so  hard  that  it  is  impossible  or  unsafe  forcibly  to  dilate 
it.  Here  the  cervix  may  be  packed  witli  iodoform  gauze  for  twentj'-four  hours,  when  it  will  be 
found  softened  and  dilatable.  Perhaps  a  tent  may  be  put  in,  but  I  have  never  used  one,  since  I 
consider  them  dangerous.     When  haste  is  not  demanded,  the  two-stage  method  maj^  be  chosen. 

During  the  third  and  fourth  month  the  abortion  is  done  in  two  stages.  On  the  first  day  the 
OS  is  opened  a  httle  with  a  Goodell  dilator,  then  with  a  curet  the  ovimi  is  broken  up,  making  cer- 
tain that  the  amnion  has  been  punctured;  then  the  cavity  of  the  uterus  is  lighth',  and  the  cer\'ix 
tightly,  packed  ^Ith  gauze  by  means  of  the  tubular  packer  shown  on  p.  908.  Pains  almost  always 
start  up  within  twelve  hours,  and  if  the  packing  is  not  expelled,  at  least  the  cervix  is  opened  enough 
to  put  in  one  finger.  If  it  is  not,  the  packing  may  be  repeated — this  time  I  usually  use  a  piece 
of  weak  iodin  gauze.  At  the  end  of  another  twenty-four  hours  the  uterus  may  be  emptied,  as 
described  under  Abortion. 

During  tlie  fifth  and  sixth  months  the  process  resembles  the  induction  of  premature  labor  more. 
The  bag  of  waters  should  be  ruptured,  and  a  small-sized  Voorhees  bag  inserted.  In  cases  of  great 
urgency  vaginal  cesarean  section  should  be  performed.  Let  me  warn  the  accoucheur  against  the 
removal  of  a  small  fetus  piecemeal  through  a  long,  narrow  cervical  canal.  It  \s-ill  tax  his  skill  to 
the  utmost,  especially  if,  as  so  frequently  happens,  the  bodj'  is  torn  off  the  head,  which  bobs  around 
in  the  blood  in  the  uterine  cavity.  If  he  attempts  this  operation,  everj'  bit  of  the  bod^'  of  the  fetus 
should  be  laid  out  on  a  clean  towel,  and  he  maj'  not  call  the  work  complete  until  all  the  parts  of 
the  fetus  are  accounted  for.  After  the  placenta  is  removed,  the  whole  interior  of  the  uterus  is 
hghtly  cureted,  and  finalh'  the  cavity  is  filled  with  gauze,  which  is  removed  the  ne.xt  day.  Where- 
ever  possible,  the  fingers  are  to  he  used  instead  of  the  curet  or  ovuin  forceps. 

There  is  no  medicine  which  will  safely  bring  on  abortion,  though  many  are  vaimted  for  the 
purpose.     Other  methods  of  inducing  abortion  have  been  named  under  Induced  Labor. 

After-treatment. — Ergot  and  hj'drastis,  of  each  10  minims,  are  administered  thrice  daily  for  a 
week.  Douches  are  not  used — only  external  washings  vc\i\v  a  weak  antiseptic  solution.  The 
woman  should  lie  abed  for  one  week  and  only  gradually  assume  her  duties. 

Prognosis. — The  induction  of  abortion  is  attended  by  a  certain,  though  in 
proper  hands  small,  mortality.  The  dangers  are  infection,  which  is  not  always 
avoidable,  since  the  woman  may  have  it  within  her,  and  perforation  of  the  uterus. 
I  consider  the  operation  of  induced  abortion  one  of  the  most  dangerous  in  obstetrics. 
The  most  painstaking  asepsis  does  not  always  guarantee  an  afebrile  convalescence. 
Perforation  of  the  uterus  by  the  curet  is  sometimes  very  easy.  It  has  happened  to 
every  accoucheur  of  experience — either  the  cervix  tears  into  the  broad  ligaments 
or  peritoneal  cavity,  or  the  curet,  even  the  finger,  goes  through  the  wall  of  the  uterus. 
In  one  recorded  case  the  uterine  muscle  was  so  soft  that  the  weight  of  the  curet  held 
vertically  on  the  extirpated  uterus  sufficed  to  make  it  go  through  to  the  table 
underneath.  I  confess  I  use  the  curet  only  \\ath  the  greatest  distrust,  and  dispense 
with  it  entirely  if  the  finger  can  gain  access  to  the  uterus.  The  ovum  forceps,  too, 
are  dangerous,  and  many  cases  are  reported  annually  of  the  drawing  out  of  coils 
of  gut  and  omentum  through  perforations  in  the  uterus.  Spiculse  of  bone  from  a 
dismembered  fetus  may  also  puncture  the  uterine  wall,  and  the  lower  uterine  seg- 
ment may  be  torn  during  forced  attempts  to  draw  the  fetus  through  it.  In  view  of 
all  this  the  operation  is  not  to  be  lightly  undertaken,  and  is  to  be  performed  with  the 
greatest  gentleness  and  circumspection.

Sterilizing  Rubber  Gloves. — Author's  Method. — P'irst,  even  new  gloves  are  tested  for  imper- 
fections l)y  filling  them  up  with  very  hot  water  and  drying  the  outside.  The  minutest  perforation 
will  thus  be  discovered.  All  imperfect  gloves  are  discarded.  The  gloves  are  now  thoroughly 
washed  inside  and  out  with  soap  and  water,  dried,  and  generously  powdered  witli  plain  pure  talcum. 
They  are  then  suspended  in  a  tall,  low-pressure  sterilizer  by  means  of  clips.  Thirty  pairs  are  done 
at  one  time,  and  ^^^th  them  are  sterilized  enough  paper  for  wrappers  (60  sheets),  30  little  bottles  of 
corn-starch,  and  3  towels.  Hanging  thus,  the  gloves  are  exposed  to  flowing  steam  for  forty-five 
minutes.  While  still  warm,  they  are  removed  from  the  sterilizer  ^ith  sterile  hands,  laid  on  the 
towels,  then  each  pair  is  wrapped  up  in  the  paper  wrappers,  using  two  sheets,  together  with  a 
bottle  of  starch.     The  packages  are  labeled  and  then  put  back  in  the  sterilizer  for  another  forty-

five  minutes' steaming.  They  are  laid  on  the  steam  radiator  i'orsix  hours,  to  lie  thoroughly  dried 
out,  and  stored  in  a  co\'ered  box. 

Before  using  the  gloves  the  hands  are  disinfected,  dried,  and  jjowdercil  with  the  corn-starch, 
and  the  gloves  are  drawn  on.  Corn-starch  is  used  on  the  hands  before  drawing  on  the  gloves,  and 
it  is  preferred,  because  it  does  not  parch  tlie  skin  as  much  as  talcum.  Talcum  must  be  used  diu-ing 
the  sterihzation — corn-starch  glues  the  gloves  together.  By  means  of  a  little  pure  Ij'sol  all  the 
talcum  is  dissolved  off  the  outside  of  the  gloves,  then  they  arc  thoroughly  rinsed  in  sterile  water 
to  remove  all  traces  of  lysol.  The  object  of  this  lysol  bath  is  twofold — first,  it  removes  the  tal- 
cum, which  even  though  sterile  may  cause  aseptic  suppuration  if  it  gets  into  tlie  wound;  second, 
the  lysol  kills  any  germ  that  might  possibly  have  gotten  on  the  gloves  from  the  time  they  were 
sterilized  until  they  enter  the  wound. 

Most  hospitals  sterilize  gloves  in  high-pressure  apparatus.  Unless  they  are  exposed  to  the 
superheated  steam  full  thirty  minutes'  absolute  sterihzation  is  not  sure,  but  such  a  method  spoils

the  rubber.  Gloves  so  treated  do  not  last  long,  and  their  elasticitj^  suffers  even  from  the  first. 
Gloves  may  be  sterilized  by  boiUng  in  plain  water  for  thirty  minutes.  They  should  be  wrapped  in 
a  thick  cloth  to  avoid  scorching. 

Gloves  may  not  be  put  in  a  sterilizer  near  a  flame  or  near  the  entry  of  superheated  air — they 
scorch  very  readily  antl  become  l)rittle. 

Lysol  Gauze  for  Tamponade. — Two  widths  of  gauze  are  required  for  packing  the  uterus, 
depending  on  the  time  of  pregnancy.  For  use  in  the  early  months  a  strip  aI)Out  three  inches 
wide  is  best,  the  gauze  being  cut  into  five-yard  lengths  and  loose  threads  carefully  removed  from 
the  edges.  A  woven  bandage  ma.y  be  bought  from  surgical  supply  houses,  and  I  use  it  instead 
of  cut  mushn.     For  packing  the  uterus  at  or  near  full  term  these  narrow  strips  would  be  useless. 

For  uterine  packing  the  gauze  is  cut  one-half  yard  wide,  into  lengths  of  12  yards.  The 
selvedge  and  cut  edge  are  folded  iu,  and  each  length  is  made  into  a  bundle,     The  bundles  are  then

thoroughly  rinsed  in  running  water,  wrung  dry  by  hand,  and  boiled  for  twenty  minutes  in  0.25  per 
cent,  lysol  solution.  A  pair  of  rubber  gloves,  two  sheets,  and  a  metal  clothes-wringer  are  now 
sterihzed  by  steam  or  boiling.  Wearing  the  gloves,  the  bundles  are  run  through  the  wringer, 
using  considerable  pressure.  Then  the  strips  are  packed  into  sterilized  Mason  jars  or  others  that 
are  large  enough,  packing  smoothly  in  circles  from  below  upward.  Thus  the  tamponade  can  be 
made  directly  from  the  jar.  The  gauze  may  not  be  rolled  and  then  placed  in  a  jar.  The  mouth 
of  the  jar  is  filled  with  a  layer  of  cotton,  the  lid  is  screwed  down  tight,  and  the  jars  are  put  in  the 
sterilizer.  They  are  sterilized  on  two  successive  days,  two  hours  each  time.  The  jars  are  then 
wrapped  in  three  layers  of  paper,  sterilized  again,  and  put  away  in  a  clean  place.  Thus  prepared, 
gauze  will  keep  sterile  for  years. 

Plain  sterilized  gauze  is  prepared  by  cutting  the  gauze,  as  it  comes  from  the  surgical  supply 
houses,  into  the  requisite  lengths,  as  just  given,  packing  into  the  jars  as  described,  and  sterilizing 
in  the  steam  chamber  every  day  for  three  days,  two  hours  each  time.
